[0002]

2. Description of the Related Art Conventionally, as one of the general structures of this type of cleaning machine, there is, for example, the structure of an instrument cleaning machine described in Japanese Patent Laid-Open No. 62-282683.

That is, in this equipment cleaning machine, a cleaning nozzle (injection device) for injecting cleaning water into the equipment is arranged in a cleaning tank for accommodating the equipment such as a flask and a test tube, and surrounds the cleaning tank. A cleaning pump (water supply pump) for supplying water to the cleaning nozzle is arranged in the housing and below the cleaning tank. In addition, a detergent containing a detergent, a finishing agent, a disinfectant, a neutralizing agent, etc. in the middle of a supply path for supplying hot water or water serving as cleaning water or rinsing water into the cleaning tank such as a water supply pipe or a hot water supply pipe. A storage box is provided.

Conventionally, there has been a case where a detergent storage box (treatment agent storage chamber) as described above is provided on one side wall of a cleaning tank, and the configuration thereof is shown in FIG.

The detergent storage box 55 is fixed to the inner wall of the cleaning tank 56, and the entire box is in a state of being projected into the cleaning tank 56. Further, the detergent storage box 55 is opened from the front surface to the front side surface of the cleaning tank 56, and forms a charging port 57 for inserting a detergent container containing a detergent or the like into the detergent storage box 55. The input port 57 is covered with an input port cover 58. The input port cover 58 is rotatably supported by a hinge 59 at the side end located on the back side of the cleaning tank 56, and is opened laterally.

A water supply hose 61 is connected to the connection port 60 a of the water supply nozzle 60, and a water supply port 62 is formed on the lower surface of the tip portion 60 b of the water supply nozzle 60 protruding into the detergent storage box 55. Then, the detergent container 63 described above is stored under the water supply port 62.

Thus, in the process in which a treatment agent such as detergent is required, water is supplied from the water supply nozzle 60 and the detergent container 63 is supplied.
The detergent inside is poured out into the washing tank 56 together with water.

[0008]

However, in the above-described instrument washer, since the whole detergent storage box is overhanging in the washing tank, it may interfere when storing the instrument. Therefore, there is a problem that the device cannot be stored sufficiently by this amount.

Further, since the water supply nozzle is attached to the rear surface of the detergent storage box and the water flow must be changed from the lateral direction to the downward direction at the tip of the water supply nozzle,
Since the flow is disturbed in this part, the flow rate of the water supply is inevitably reduced, and the water supply time becomes long.

Further, when the loading port cover is closed, no force acts on the closing side of the loading port, so that the cover cannot be brought into close contact with the loading port reliably. For this reason,
A gap is likely to open between the inlet cover and the inlet, and during cleaning or rinsing, cleaning water or rinsing water may enter, and the detergent in the detergent storage box may undesirably flow out. It was To prevent this, a structure in which a spring or the like is used to urge the closing port to the closing side is required, but there is a problem in that the structure becomes complicated accordingly.

The present invention relates to a washer such as a dish washer and an instrument washer, and solves such a problem.

According to a third aspect of the present invention, in the configuration of the second aspect, the lower end of the input port cover is extended below the bottom surface of the processing agent storage chamber.

[0015]

In the structure according to the first aspect, the rear side of the processing agent storage chamber is projected to the outside of the cleaning tank, so that the processing agent storage chamber is prevented from protruding into the cleaning tank.

In addition, since the supply pipe is connected to the ceiling surface protruding outside the cleaning tank of the treatment agent storage chamber, it is stored below the water supply port without changing the flow of water in the vicinity of the water supply port. Water can be supplied to the detergent.

In the structure according to the second aspect of the invention, the loading port cover naturally rotates up to the vertical direction by its own weight with the upper end portion as a fulcrum. Here, the opening surface of the charging port is an upwardly inclined surface so that the charging port cover contacts the peripheral edge of the charging port before it becomes vertical. Causes a force to act in the direction of closing the input port. Therefore, the input port cover surely adheres to the input port.

According to the third aspect of the present invention, the lower end of the input port cover extends below the bottom surface of the processing agent storage chamber, so that the water that hits the front surface of the processing agent storage chamber at the time of cleaning and rinsing will not enter the input port. Unless it goes around to the back side of the cover, it cannot enter between the inlet cover and the processing agent storage chamber.

The hot water supply detergent input box 24 and the water supply detergent input box 25 function as the treating agent storage chamber of the present invention. Hereinafter, these detergent input boxes 24, 25 will be described.
The detailed structure of the above will be described with reference to FIGS. Since the detergent input boxes 24 and 25 have the same structure, the water supply detergent input box 25 will be described here as a representative.

The detergent supply box 25 for supplying water (hereinafter referred to as a supply box) is a rectangular parallelepiped box made of stainless steel, and the front surface of the box is open, and a detergent container containing a treating agent such as a detergent (described later). An input port 44 is provided for inserting the input into the input box 25.

The charging box 25 is fitted into a charging hole 45 formed in the side wall of the cleaning tank 2 in the shape of the charging box 25, and about three-fourths of the rear side is the outside of the cleaning tank 2. It is fixed to the side wall of the cleaning tank 2 in a state of overhanging. Here, so-called burring processing is performed in which the edge 45a of the filling hole 45 is set up toward the outside of the cleaning tank 2, and welding is performed between the tip of this edge 45a and the outer peripheral surface of the charging box 25. By doing so (A in FIG. 3), the charging box 25 is fixed to the side wall of the cleaning tank 2.

A charging box 2 that projects to the outside of the cleaning tank 2.
A connection hole 46 to which the tip of the second water supply hose 34 guided from the electromagnetic water supply valve device 32 is connected is formed in the top surface 25 a of the No. 5. And the second water supply hose 34
Is inserted from above into the connection hole 46, and the peripheral edge of the connection hole 46 is fitted into the fitted groove 47a of the fitted portion 47 provided at the front end of the insertion box 25. 25a. At the tip of the second water supply hose 34,
A water supply port 48 is formed, and water that has passed through the hose is discharged downward from the water supply port 48.

Reference numeral 49 denotes a stainless-steel input port cover that covers the input port 44 on the front surface of the input box 25. An upper end portion 49a of the input port cover 49 is provided at the upper edge of the input port 44. It is rotatably supported by a support shaft 50. This inlet cover 49 is used for cleaning and rinsing.
This is to prevent the wash water and rinse water sprayed from the upper nozzle 8 and the lower nozzle 11 from entering the input box 25.

The input port cover 49 normally rotates naturally up to the vertical direction by its own weight, thereby closing the input port 44. Here, the bottom side of the input port 44 is arranged to come out slightly ahead of the top side. That is, the input port 4
The opening surface of No. 4 is inclined several degrees (3 degrees in this embodiment) from the vertical direction so that it does not face the horizontal direction but faces slightly upward. Therefore, the input port cover 49 comes into contact with the peripheral edge of the input port 44 and closes the input port 44 before it is rotated fully by its own weight in the vertical direction. Therefore, when the input port cover 49 is closing the input port 44, a force always acts in the direction of closing the input port 44 due to the weight of the input port cover 49.

Side guard pieces 51, 51 are provided at both ends of the charging port cover 49 to cover the front portion of the side surface of the charging box 25 when the charging port 44 is closed. Further, the lower end 49b of the input port cover 49 is also the same as the input port 4
It is extended so as to come to a position below the bottom surface 25b of the charging box 25 when the 4 is closed.

Numeral 52 designates the charging box 25 so that it is arranged just below the water supply port 48 at the tip of the second water supply hose 34.
It is a detergent container stored inside. The detergent container 52 is a container having an open top surface, and is used to store a processing agent such as detergent stored in the input box 25. This cleaning container 52
A handle 53 for holding the container is provided on the side surface of the. The handle 53 is sized so that when the detergent container 52 is stored at a position where it can receive water from the water supply port 48, that is, at a position just below the water supply port 48, the detergent container 52 is completely contained in the throw-in box 25. For this reason, if the detergent container 52 is not firmly stored to the back and has not reached the position almost directly below the water supply port 48, the handle 53 will be in a state of being out. Therefore, in this case, By closing the input port cover 49 and pushing the handle 53 with the cover 49 to put it in the input box 25, the detergent container 52 can be reliably arranged at a position almost directly below the water supply port 48. Therefore, water can be surely supplied into the detergent container 52, and the detergent can be surely poured out together with the water supply.

Now, in the above configuration, when a treatment agent, for example, a detergent is stored in the detergent feed box 25 for water supply,
First, the detergent is put in the detergent container 52. Then, the input port cover 49 is opened, the detergent container 52 containing the detergent is stored in the input box 25 through the input port 44, and the input port cover 49 is closed (when the hand is released, the input port cover 49 is closed by its own weight). with this,
The storage of the detergent in the input box 25 is completed.

Next, when the washing process is started, first, the water supply solenoid valve device 32 is operated to supply water into the input box 25 from the water supply port 48 of the second water supply hose 34. As a result, water is poured into the detergent container directly below the water supply port 48,
Eventually, the detergent in the container overflows with the water overflowing from the detergent container 52. Water mixed with detergent should be put in the inlet cover 4
9 is pushed open, and it flows into the cleaning tank 2 through the opened gap.
Thus, the detergent is supplied into the cleaning tank 2 together with the water. In some cases, hot water may be supplied during the washing process. In this case, the detergent is put in the hot water supply detergent feeding box 24.

As described above, in the instrument washer of the embodiment of the present invention,
Since the rear side of the water supply detergent input box 25 (hot water supply detergent input box 24) is projected to the outside of the cleaning tank 2, the input box 2
It is possible to suppress the protrusion of No. 5 into the cleaning tank 2. Therefore, when the lower rack 7 containing test tubes, flasks, etc. is stored in the cleaning tank 2, the input box 25 is less likely to interfere with the equipment, and the equipment can be stored sufficiently. .

In addition, since the water supply hose 34 is connected to the top surface 25a of the input box 25 which extends outside the cleaning tank 2, unlike the case where the hose 34 is connected to the rear surface or the side surface of the input box 25. The water can be supplied from the water supply port 48 toward the detergent stored below without changing the flow of water in the vicinity of the water supply port 48 of the hose 34, the water supply flow rate does not decrease, and the water supply time does not extend.

Further, the opening surface of the input port 44 of the input box 25 is an inclined surface facing upward, and when the input port cover 49 is closing the input port 44, a force acts in the direction of closing the input port 44 by its own weight. Since this is done, the input port cover 49 surely adheres to the input port 44. Therefore, a gap is unlikely to be opened between the charging port 44 and the charging port cover 49, and during cleaning and rinsing, cleaning water and rinsing water sprayed from the upper nozzle 8 and the lower nozzle 11 are less likely to enter the charging box 25. It is possible to prevent the treating agent such as a detergent from flowing out of the charging box 25 at an undesired time, such as during the preliminary washing step before the washing step.

Further, when the lower end 49b of the charging port cover 49 is flush with the bottom surface 25b of the charging box 25, during cleaning and rinsing, the lower nozzle 11 sprays upward (obliquely upward due to centrifugal force) and charges from below. There is a possibility that cleaning water or rinse water that hits the front surface of the box 25 may enter between the input port cover 49 and the input box 25. However, here, the lower end 49b of the input port cover 49 is extended below the bottom surface 25b of the input box 25, and the water hitting the front surface of the input box 49 must flow to the back side of the input port cover 49. Cover 49
Cannot enter between the input box 25 and the input box 25. Therefore, it is possible to prevent the wash water and the rinse water from entering between the input port cover 49 and the input box 25 into the input box 25, and prevent the processing agent such as a detergent from undesirably flowing out of the input box 25. .

In the embodiment of the present invention, the instrument washer is used, but the washer of the present invention is not limited to this and may be a dishwasher.

[0054]

According to the first aspect of the cleaning machine of the present invention, the rear side of the processing agent accommodating chamber provided on one side wall of the cleaning tank is projected to the outside of the cleaning tank. It is possible to prevent the agent storage chamber from protruding into the cleaning tank. Therefore, when storing a rack containing test items such as test tubes and flasks in the cleaning tank, the treatment agent storage chamber is less likely to interfere with the item to be cleaned, and the item to be cleaned should be stored sufficiently. Will be able to.

In addition, since the supply pipe is connected to the top surface of the cleaning bath of the processing agent storage chamber, which is extended to the outside, unlike the case where the supply pipe is connected to the rear surface or the side surface of the processing agent storage chamber, Without changing the flow of water near the water supply port of the supply pipe, water can be supplied from this water supply port toward the detergent stored below, the water supply flow rate does not decrease, and the water supply time does not extend.

According to the configuration of claim 2 of the washing machine of the present invention, the opening surface of the input port of the processing agent storage chamber is an upwardly inclined surface, and when the input port cover closes the input port, the self-weight is applied. Since the force is applied in the direction to close the charging port, the charging port cover surely adheres to the charging port. Therefore, it is difficult to open a gap between the charging port and the charging port cover,
During cleaning and rinsing, the cleaning water and rinsing water sprayed from the spraying device are less likely to enter the processing agent storage chamber, and the processing agent such as detergent can be prevented from flowing out of the processing agent storage chamber when it is not desired. .

According to the third aspect of the cleaning machine of the present invention, if the lower end of the inlet cover is flush with the bottom surface of the processing agent storage chamber or is short, the cleaning is performed from below by the spraying device during cleaning and rinsing. The cleaning water and rinse water that hit the front of the agent storage chamber may enter between the inlet cover and the treatment agent storage chamber.Here, the lower end of the inlet cover is lower than the bottom of the treatment agent storage chamber. The water that extends downward and hits the front surface of the processing agent storage chamber cannot enter between the input port cover and the processing agent storage chamber unless it goes around to the back side of the input port cover. Therefore, it is possible to prevent the wash water and the rinse water from entering between the input port cover and the treatment agent storage chamber, and prevent the treatment agent such as detergent from undesirably flowing out from the treatment agent storage chamber.
