[Detailed description of the device]

[0001]

[Industrial applications]

 The idea is to produce a block of ice cubes (hereinafter referred to as "block ice") with an ice making mechanism in the upper part, and to stack the obtained block ice in a lower ice storage chamber to store the block ice from the ice storage chamber. The present invention relates to a door structure that prevents the block ice from being discharged and dropped outside the room when taking out, and can be taken out easily even if the stacking level changes.

[0002]

[Prior art]

 At coffee shops, restaurants and other eating and drinking establishments, square ice cubes (ice cubes) produced by automatic ice makers are floated in beverages or used as cooling beds for various foodstuffs. However, since the ice blocks are of a fixed shape, they give a visually unpleasant impression when used for the aforementioned purposes. Therefore, a block ice of the required size is pierced with an ice pick to obtain an irregularly shaped ice block, which gives visual peculiarity to give the customer a sense of luxury and enhances the product value. ..

This block ice is generally produced in a factory by a large-scale can ice making device. For example, an ice can is immersed in brine filled in an ice making tank, and this ice can is filled with ice making water. Then, when the brine is cooled by a cooler, water freezes in the ice can, and by removing it from the can, a block-shaped ice mass is obtained. Since this ice block is generally too large, it is cut into the required blocks and supplied to users.

[0004] Thus, in the past, in order to manufacture block ice, large-scale factory equipment was required, but in order to manufacture this easily, an automatic ice machine for block ice for consumers was proposed. There is. This automatic ice maker has a basic structure in which a single block ice is produced by an ice making mechanism provided inside the casing and the obtained ice is discharged and stored in an ice storage chamber defined below the inside of the casing. ing.

The size and weight of the block ice produced by this automatic ice making machine are, for example, about 800 g in a size of 50 mm × 80 mm × 200 mm. Compared to conventional ice cubes, which are as small as about 36 mm3 and are lightweight, block ice has a much heavier weight. Therefore, in the case of the ice cube, even if the ice cube is discharged and dropped as it is into the ice storage chamber, problems such as impact noise and ice cracking do not occur. However, since block ice has a considerable weight and bulk size as described above, if it is released from the ice making mechanism to the ice storage chamber, the ice will be stored in the ice storage chamber depending on the release head. There is a problem that it breaks when it collides with the bottom of the chamber.

Further, it is pointed out that a large impact sound generated when the block ice collides with the bottom of the ice storage chamber becomes an environmental noise and the ice storage chamber may be damaged by frequent falling of heavy objects. It In addition, in order to store the block ices in the ice storage chamber maximally and efficiently, it is effective to stack the ices in a line. However, the random release of bulky block ice into the ice storage compartment has the drawback of reducing the effective stock amount.

Therefore, one proposal for dealing with the above-mentioned various problems has been filed by the applicant of the present invention as the invention “automatic ice maker for block ice”. In the automatic ice making machine according to the previous application, a lifter device having a transfer body capable of reciprocating up and down between an ice making mechanism and an ice storage chamber is disposed on the inner rear surface side of the housing. According to the automatic ice maker having this configuration, the block ice produced by the ice making mechanism is transferred to the ice block release position of the ice storage chamber via the transfer body and is released, so that the block ice is dropped from a high position. Never. Therefore, it is possible to effectively prevent the block ice from breaking and making a loud impact noise. Further, the block ice transferred by the transfer body can be discharged so as to be sequentially stacked from below the ice storage chamber, so that the block ice can be efficiently stored in the ice storage chamber.

[0008]

[Problems to be solved by the device]

 In the automatic ice making machine, in order to smoothly release the block ice from the lifter device to the ice storage chamber, the inner bottom surface of the ice storage chamber is set to be inclined downward toward the front side. That is, the block ice released from the lifter device is stacked and stored at a position where the bottom end of the ice storage chamber slides down and the tip of the block ice comes into contact with the front wall of the ice storage chamber while being inclined downward toward the front side. In this case, on the front side of the ice storage chamber, an opening that functions as a block ice take-out port and a door that opens and closes the opening are provided, so that the block ice stacked up to the level of the opening is Stacking is done with the tip abutting the inner surface of the door and preventing slipping.

Therefore, when the block ice is taken out from the ice storage chamber, if the door is opened, there is a risk that the block ice, which has come into contact with the inner surface of the door and is prevented from sliding down, may be discharged and dropped outside the room. As mentioned above, since the block ice has a considerable weight, there is a risk that the block ice collides with the floor surface and is broken, or the worker is hit and injured.

Therefore, it is conceivable to set the opening position of the opening at a position higher than the uppermost layer level of the blow ice in the full state. However, it is pointed out that if the stacking level decreases due to the consumption of block ice, the height difference between the opening and the stacking level of block ice increases, and the extraction of block ice becomes a very complicated work. In other words, how to prevent the block ice from being released and dropped to the outside when the door is opened, and to facilitate the removal when the stacking level changes due to the consumption of the block ice. Or is a new problem to be solved.

[0011]

[The purpose of the device]

 In view of the above-mentioned problems, the present invention has been proposed in order to solve the problems appropriately, and prevents the block ice from being released and dropped from the ice storage chamber when the door is opened, and at the same time, the stacking level is improved. It is an object of the present invention to provide a door structure that allows the block ice to be easily taken out even if the temperature drops.

[0012]

[Means for Solving the Problems]

 In order to overcome the above-mentioned problems and preferably achieve the intended purpose, the present invention is provided with an ice making mechanism on the upper part of a housing, and a block-shaped ice block manufactured by the ice making mechanism is provided below the ice making mechanism. In an automatic ice making machine for block ice configured to stack and store in a defined ice storage chamber, the block ice is arranged in a plurality of stages in a vertical direction corresponding to the opening opened on the front side of the ice storage chamber, and the openings are partially formed. A plurality of inner doors that can be opened and closed, a locking unit that locks the inner doors in a closed state, the opening provided in the front side of the housing and in a state where all the inner doors are closed. Is characterized by being configured with an outer door that can be completely closed from the outside of the inner door.

A refrigeration mechanism 16 including a compressor 14 and a condenser is disposed below the ice storage chamber 13, and a refrigerant is supplied from the refrigeration mechanism 16 to an evaporator 17 (described later) of the ice making mechanism 12. There is. Further, a lifter device 20 is disposed on the inner back surface side of the housing 10 so as to be capable of reciprocating up and down between the ice making mechanism 12 and the ice storage chamber 13. As will be described later, the lifter device 20 functions to transfer the block ice 11 produced by the ice making mechanism 12 to the vicinity of the bottom of the ice storage chamber 13 and gently release the block ice 11 to the ice storage chamber 13.

(Regarding Ice Making Mechanism) As shown in FIG. 2, the inside of the casing 10 is divided into a front side storage space 22 and a rear side storage space 23 by a partition plate 21 and communicates with the ice storage chamber 13. In the back side storage space 23, a rectangular cylindrical ice making chamber 24 made of a metal having a good thermal conductivity is vertically arranged and fixed. Inside the ice making chamber 24, a plurality of small ice making chambers (none of which are shown) are defined in parallel by partition plates so that a plurality of block ices 11 can be produced at one time. An evaporator 17 led out from the freezing / freezing mechanism 16 is closely fixed in a meandering manner on the opposite outer surfaces of the ice making chamber 24, and the operation of the freezing mechanism 16 promotes heat exchange of the vaporized refrigerant in the evaporator 17. The ice making chamber 24 is cooled to below freezing. It is to be noted that hot gas is supplied to the evaporator 17 by switching the valve of the refrigeration system during the deicing operation, so as to accelerate the melting of the freezing of the ice cube inner wall and the block ice 11.

As shown in FIG. 2, an ice making water tank 26 is arranged below the front side storage space 22, and an ice making water supply pipe 28 led out from this tank 26 via a circulation pump (not shown).

It is sprinkled and supplied to the outside of 24 and flows down to accelerate the melting of the freezing between the inner wall surface of each ice making chamber and the block ice 11. The deiced water that has flowed down the outside of the ice making chamber 24 is collected in the ice making water tank 26 via a water collecting plate 34 described later and used as ice making water.

(Blower Fan) In the rear side storage space 23, as shown in FIG. 2, a blower fan 59 that sucks the air in the ice storage chamber 13 and blows it toward the ice making chamber 24 is disposed. .. The blower fan 59 is operated during the ice making operation and is controlled so as to be stopped when the ice making operation is switched to the deicing operation. That is, the ice storage chamber 13 and the evaporator 17 that are cooled during the ice making operation are circulated to the ice storage chamber 13 by circulating cold air that has been subjected to heat exchange to cool the ice storage chamber 13. Since the blower fan 59 is stopped during the deicing operation, warmed air is not circulated to the ice storage chamber 13 to raise the room temperature, and the ice storage chamber 13 can always be kept at a low temperature. it can .

(Regarding Water Collecting Plate) As shown in FIG. 2, a water collecting plate 34 rotatably supported by a fixed portion 44 inside the housing faces directly below the ice making chamber 24 in the ice making mechanism 12. There is. The water collecting plate 34 is biased by an elastic member (not shown) so as to incline downward toward the ice making water tank 26 which always faces the lower right (in FIG. 2). Then, the ice making water which has not reached the freezing in the ice making chamber 24 during the ice making operation is collected in the ice making water tank 26 through the water collecting plate 34. Further, the deicing water that has flowed down the outside of the ice making chamber 24 during the deicing operation is also collected in the ice making water tank 26 via the water collecting plate 34, like the ice making water. The block ice 11 dropped from the ice making chamber 24 by the deicing operation slides the bottom surface of the water collecting plate 34 while tilting the water collecting plate 34 in the counterclockwise direction, and the transfer body 47 of the lifter device 20 ( It will be accommodated smoothly (see below).

(Regarding the Lifter Device) On the inner rear surface side of the casing 10, as shown in FIG. 2, the block ice 11 produced by the ice making mechanism 12 is defined in the inside of the casing 10 in an ice storage chamber. A lifter device 20 for transferring and releasing the ice block to the ice block 13 release position is provided. The lifter device 20 is slidably disposed on vertically extending guide rods 49, 49 in concave grooves 48, 48 (only one is shown) formed on both left and right sides of the housing 10. In addition, a transfer body 47 capable of receiving a plurality of block ices 11 sliding down the water collecting plate 34 in parallel and in an upright state is provided. Wires 52, 52 are connected to the transfer body 47. The wires 52 are wound and unwound by forward and reverse biasing of a motor 46 with a brake disposed in the front side storage space 22. Then, by energizing the motor 46 in the forward and reverse directions, the transfer body 47 moves between the standby position for receiving the block ice 11 dropped from the ice making chamber 24 and the release position for releasing the block ice 11 to the ice storage chamber 13. It is set to move up and down along the guide rods 49, 49.

The transfer body 47 supports the block ice 11 in an upright state when the transfer body 47 faces the standby position, and when the transfer body 47 descends and reaches the ice block discharge position. An ice block discharging mechanism 51 for discharging the block ice 11 received inside toward the ice storage chamber 13 is provided. That is, when the transfer body 47 descends, the ice block discharging mechanism 51 operates when the descending of the discharging mechanism 51 is blocked by the bottom portion 13a of the ice storage chamber 13 or the block ice 11 that has already been stored, and the transfer is performed. It is configured to release the block ice 11 received by the body 47. Thereby, as shown in FIG. 4, the block ices 11 can be sequentially stacked in the ice storage chamber 13.

(Regarding Ice Storage Chamber) As shown in FIG. 2, the ice storage chamber 13 defined below the ice making mechanism 12 moves the block ice 11 discharged from the transfer body 47 of the lifter device 20 in the front-back direction. The size is set so that two rows can be stored. The bottom portion 13a of the ice storage chamber 13 is set so as to incline downward toward the front side, and a drainage drainboard 62 is arranged on the bottom portion 13a. That is, the block ice 11 discharged from the transfer body 47 slides down on the slanting slats 62 and is stored in order from the front side of the ice storage chamber 13. Further, a drain pipe 61 that extends to the outside of the room is provided at the lower inclined end of the bottom portion 13 a, and melted water generated when the block ice 11 stacked and stored in the ice storage chamber 13 is melted is discharged via the drain pipe 61 to the outside of the machine. Is configured to be discharged to.

As shown in FIG. 1, an opening 10 a having a required size is opened on the wall surface of the housing located on the front side of the ice storage chamber 13, and the opening 10 a is completely opened and closed by an outer door 18. It is supposed to be done. A plurality of inner doors 19 are vertically arranged in the opening 10a in a plurality of steps, and each inner door 19 is attached to one inner edge of the opening 10a via a hinge 63 so as to be openable and closable. The inner door 19 is configured so that the opening 10a can be partially opened while the outer door 18 is open. That is, according to the stacking level of the block ice 11 stored in the ice storage chamber 13 in a stacked manner, as shown in FIGS. Is always easy to take out. Even when the block ice 11 is stacked above the lower edge of the opening 10a (a state in which the tip of the block ice 11 is in contact with the inner surface of the inner door 19), it is possible to use the inner door 19 properly and It is possible to effectively prevent the ice 11 from being discharged and dropped outside the room.

As shown in FIG. 3, a supporting member 65 that constitutes the locking means 64 is arranged near the end of the inner door 19 opposite to the end where the hinge 63 is arranged. An engaging member 66, one end of which can project from the end of the inner door 19, is slidably arranged. A knob 67 is projectingly provided on a portion of the engaging member 66 facing the front side of the inner door 19, and by operating the knob 67, the engaging member 66 is positioned and moved between a lock position and a release position. It has become.

At the inner edge of the opening 10a facing the end portion where the engaging member 66 of the inner door 19 is disposed, a pair of protruding strips 68a, 68b protruding inward of the opening 10a are formed. A stopper 68 having a U-shaped flat cross section is arranged over the vertical region where the three inner doors 19 face. The outer protruding piece 68a of the stopper 68 allows opening and closing with the engagement member 66 of the inner door 19 positioned at the release position, but opens with the engagement member 66 positioned at the lock position. Are set to prevent. That is, when the inner door 19 is opened and the engaging member 66 faces between the two protruding strips 68a and 68b, the engaging member 66 is moved from the released position to the locked position, so that the engaging member 66 is engaged. The member 66 abuts on the outer protruding piece 68a, and the inner door 19 is locked in the closed position. Thus, when the block ice 11 released from the transfer body 47 slides down on the already stacked block ice 11 and collides with the inner surface of the inner door 19, the inner door 19 is easily opened. Can be prevented.

The inner protruding piece 68b of the stopper 66 is set to have a size with which the engaging member 66 positioned at the release position abuts, and when the inner door 19 closes the opening 10a, the inner door 19b is closed. Is configured to prevent inward pivoting beyond the opening edge.

A machine room 69 is defined below the ice storage room 13 in the housing 10, and a refrigeration mechanism 16 including a compressor 14 and a condenser is arranged in the machine room 69. As described above, the evaporator 17 led out from the refrigerator 16 is closely fixed to the outer surface of the ice making chamber 24 of the ice making mechanism 12, and the ice making chamber 24 is circulated by the refrigerant and hot gas circulated and supplied to the evaporator 17. Are cooled and heated. By arranging the cooling / freezing mechanism 16 below the housing 10 as described above, the ice storage chamber 13 and the opening 10a are located above the installation surface by a required height without increasing the height of the housing 10. It can be provided in. As a result, when the block ice 11 is taken out from the vicinity of the bottom of the ice storage chamber 13, the worker does not have to bend over, and the taking out can be performed in a comfortable posture. Further, the heavy refrigeration mechanism 16 is arranged below the housing 10, which has the advantage of stabilizing the ice making machine itself.

As shown in FIG. 2, the ice storage chamber 13 is provided with an ice storage completion detection switch SW for detecting that the block ice 11 stacked and stored in the ice storage chamber 13 has reached a certain amount (full state). Has been done. The detection switch SW functions to stop the ice making / de-icing operation via a control means (not shown) when detecting that the storage level of the block ice 11 has reached a certain amount by repeating the ice making operation.

[0029]

[Operation of the embodiment]

 Next, the operation of the door structure of the block ice automatic ice maker according to the embodiment will be described.

When the ice making operation of the automatic ice making machine is started, the cooling medium is circulated and supplied to the evaporator 17 provided in the ice making chamber 24 to cool the ice making chamber 24. Further, the blower fan 59 shown in FIG. 2 starts to operate, and the cold air that has undergone heat exchange between the ice making chamber 24 and the evaporator 17 is circulated and supplied to the ice storing chamber 13 so that the ice storing chamber 13 is cooled. Cooling is done.

The ice making water in the ice making water tank 26 is pumped to the ice making water sprinkler 29 through the ice making water supply pipe 28 by the drive of the circulation pump, and is sprayed from the water sprinkler 29 to the inner surface of each ice making chamber. To be done. The supplied ice making water flows down while contacting the inner wall surface of each ice making chamber while being cooled, returned to the ice making water tank 26 through the water collecting plate 34, and provided for recirculation. Then, while the circulation of the ice making water is repeated, the ice making water freezes on the inner wall surface of each ice making chamber to form an ice layer. Then, when the ice-making operation progresses and it is detected by the appropriate detecting means that the complete block ice 11 has grown in the ice-making small chamber, the circulation supply of the ice-making water is stopped and the ice-making operation is completed.

Next, hot gas is supplied to the evaporator 17 by switching the valve of the refrigeration system to heat the ice making chamber 24, and at the same time, to the deicing water sprinkler 31 via the deicing water supply pipe 32. Is supplied. This deicing water flows down on the outer surface of the ice making chamber 24, and promotes melting of the ice-making surface between the inner wall surface of each ice making small chamber and the block ice 11. The deiced water flowing down the outside of the ice making chamber 24 is dropped and stored in the ice making water tank 26 through the water collecting plate 34. Further, when switching to the deicing operation, the blower fan 59 is controlled to stop, so that the air heated by the deicing operation is prevented from being supplied to the ice storage chamber 13 and the ice storage chamber 13 is kept at a low temperature. Is becoming

When the deicing operation progresses and the icing surface between the inner wall surface of each ice making chamber and the block ice 11 melts, the block ice 11 is separated from the ice making chamber by its own weight and passes through the water collecting plate 34. And is received by the transfer body 47 of the lifter device 20 in an upright state. When this is detected by an appropriate detection means, the motor with brake 46 is urged in the forward rotation direction, and the transfer body 47 receiving the block ice 11 starts to descend.

When the transfer body 47 arrives at the ice block discharging position of the ice storage chamber 13 (the position where the downward movement of the ice block discharging mechanism 51 is prevented), the ice block discharging mechanism 51 provided in the transfer body 47 is activated to operate the block ice. 11 is discharged toward the ice storage chamber 13. The block ice 11 slides down on the drainboard 62 and is stored at a position where it comes into contact with the front wall of the ice storage chamber 13 (see FIG. 2). The transfer body 47 that has released the block ice 11 is moved up to the standby position and stopped by the reverse rotation of the brake motor 46, whereby the work of releasing the block ice 11 is completed.

When the block ice 11 is stacked and stored above the lower end edge of the opening 10a, the block ice 11 discharged from the transfer body 47 is the top block ice already stacked. It is released onto the block ice 11, slides down on the block ice 11, and is stored at the position where the tip of the block ice 11 contacts the inner surface of the inner door 19 (see FIG. 4). At this time, since the inner door 19 is locked by the locking means 64 so that it cannot be opened in the closed state, it cannot be accidentally opened by the impact of the block ice 11 abutting on it.

When a predetermined amount of block ice 11 is stored in the ice storage chamber 13 by repeating the above-described ice making operation and deicing operation, the ice storage completion detection switch SW detects this and the ice making operation is stopped. To be done.

Next, when the block ice 11 is taken out from the ice storage chamber 13, as shown in FIG. 1, with the outer door 18 open, the inside of the appropriate position is selected according to the stacking level of the block ice 11. This is done by opening the door 19. That is, for example, when the block ice 11 is stacked and stored up to the position where the inner door 19 of the middle stage is disposed as shown in FIG. 4, the uppermost block ice 11 is opened by opening the inner door 19 of the upper stage. Take out. At this time, even if the inner door 19 is opened, the block ice 11 stored in the ice storage chamber 13 is not discharged and dropped to the outside from the opening 10a. Further, since the height difference between the opening level of the upper inner door 19 and the uppermost block ice 11 is small, the operator can easily take out the block ice 11.

Further, as shown in FIG. 5, when the stacking level is lowered to the position where the lower inner door 19 is disposed due to the consumption of the block ice 11, it is possible to open the block ice 11 only by opening the upper inner door 19. Since it is inconvenient to take 11 out, the inner door 19 in the middle stage is also opened. As a result, the height difference between the opening level of the opening 10a and the uppermost block ice 11 becomes small, and the block ice 11 can be taken out very easily.

[0039]
