[Industrial applications]

 The present invention relates to a drainage basin for a refrigerator for collecting wastewater from a refrigerator adjacent to a work room such as a supermarket and flowing the wastewater into sewers or the like.

[0002]

[Prior art]

 In general, a floor of a supermarket work room or a refrigerator is provided with a meeting place (drainage basin) for collecting wastewater and flowing it to sewers.

FIG. 10 shows an example of an arrangement structure of a work room A, a refrigerator B and a freezer C provided adjacent to a product display room of a supermarket and an arrangement structure of a hall (drainage basin) used therein. Then, a plurality of halls 101 are provided at appropriate intervals in a refrigerator or a work room, and adjacent halls are connected by drainage channels 102a and 102b such as drains or pipes, so that the drainage flowing on the floor 103 The waste water that has flowed to an appropriate meeting place is guided to sewers (not shown) after removing fats and the like from a predetermined drainage channel 102b with a grease trap 104.

By the way, the conventional meeting room 101 provided in the working room A, the refrigerator B, etc. has a downward slope with the bottom of the meeting room 101 toward the central part, as shown in, for example, Japanese Utility Model Publication No. 63-32203. The drainage channels 102a and 102b are connected to the center of the bottom of the meeting place.

[0005] In such a hall, various measures have been taken in order to remove dust in the drainage flowing down from the floor surface 103 and to prevent odor leakage from the sewage side. For example, in Japanese Utility Model Publication No. 63-32203, as shown in detail in FIG. 11, a step is formed on the inner surface of the hall 101 formed by the concrete pit 105 and the bottom inclined surface 101a of the hall, which are installed in advance. An upper lid 107 having a water passage hole 107a is formed on the stepped portion 106, and the stepped portion 106 is supported on the outer periphery of the upper part of the drainage basin 108 arranged inside the hall 101. A structure is provided in which a flange 108a is provided, and a drainage basket 109 having a water drain hole 109a is detachably provided inside the drainage basin 108.

Then, a water storage portion 108b is formed along the lower inner peripheral surface of the drainage basin 108, and the inner lid is provided above the drainage port 110 provided inside the inner peripheral wall 108c of the water storage portion with a required space. 111 is provided, a peripheral wall 111a supported by the bottom of the water storage portion 108b is provided on the outer periphery of the inner lid 111, and a water passage hole 111b is formed in the lower portion of the peripheral wall 111a.

The drainage flowing from the water passage hole 111b through the drainage port 110 is guided to the drainage channels 102a and 102b at the center of the bottom of the mortar-finished hall through the inclined surface 101a at the bottom of the hall. And so on.

[0008]

[Problems to be solved by the device]

 However, such a conventional type requires complicated installation of concrete pits in the hall and mortar finishing with a sloping floor at the bottom of the hall. It is also troublesome, and due to the sloped surface at the bottom of the hall, it is inevitable that the outflow level of the drainage must be deep, and it is necessary to dig deeper for that. It takes time.

[0009] In particular, the hall must be gradually downgraded from the upstream side to the downstream side, but if the drainage level of the hall on the upstream side becomes deeper as before, the further it goes downstream There was a problem that it could not be used during a short period of work, such as a refurbished store, because it took time to dig.

Therefore, the present invention eliminates the above-mentioned problems in the conventional hall, eliminates the need to install a concrete pit in the hall in advance, or eliminate the need for mortar finishing with a sloping floor at the bottom of the hall. In addition to being easy to do, the floor level can be easily set, and the level of drainage is shallow to minimize the work of digging, and it can be installed sufficiently even in a short construction period such as a renovated store. The purpose is to provide a possible drainage basin for refrigerators.

In addition, the present invention provides a refrigerator drainage basin that ensures cold air leaks and odor leaks by the trap structure provided in the drainage basin body, and that can easily clean the garbage basket and the water storage part. The purpose is to do.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the refrigerator drainage basin of the present invention is a drainage basin having a drainage port extending from the peripheral wall of the drainage basin body so that the level of drainage can be kept shallow. It is a thing. That is, a water storage part is formed in the lower part of the drainage basin body, and a drainage port communicating with the drainage pipe on the downstream side is formed in the peripheral wall of the water storage part. In addition, a wall that keeps the drainage of the water storage part at a constant height near the drainage port is erected from the bottom of the drainage container main body, and a trap plate whose bottom edge is immersed in the drainage maintained at a certain height It is provided inside the body to form a trap structure. Further, a bracket is fixedly provided on the outer periphery of the drainage basin body, and a level adjusting bolt for adjusting the level height of the drainage basin is attached to the bracket.

As a material for the drainage basin, an alloy having corrosion resistance and strength, such as stainless steel, is preferable. By directly attaching a drainage pipe to the drainage port, it is not necessary to install a concrete pit in the hall in advance, or to finish the bottom of the hall with mortar with an inclined surface, and to reduce the level of drainage. Therefore, there is little digging work, and in the case of short-term renovation work, the chiseling work can be simplified and the construction can be simplified. In addition, the level height of the drainage basin can be easily set by adjusting the level adjustment bolts provided on the bracket.

It is preferable that the drainage port is formed by welding a stainless steel screw-in pipe joint because the pipe can be easily connected.

[0015]

[Work]

 According to the above-mentioned refrigerator drainage basin, when the drainage flowing down the floor flows from the water hole in the top lid, this drainage flows from the upper opening of the drainage basin body into the inside of the garbage removal basket and forms in the basket. It passes through the drain hole and flows to the bottom of the drainage basin body. For this reason, the dust contained in the wastewater is removed by the dust-removal basket, and the wastewater that has passed through the basket flows down to the water storage section and accumulates.

When the water level in the reservoir increases and the water level reaches the upper edge of the wall portion standing from the bottom of the reservoir, the upper edge overflows and the drain outlet on the outer circumference of the body passes through the downstream drain pipe. Discharged into the sewer.

As described above, since the drainage of the water storage portion overflows the wall and flows downstream, a certain amount of drainage water is stored in the water storage portion, and the drainage water of the water storage portion is near the drainage port. Since a lid-shaped trap body with the lower edge of the peripheral wall submerged and a trap plate with the lower edge submerged are provided, the odor generated downstream can be prevented from flowing above the drainage basin due to the water sealing action of the stored water. At the same time, cold air in the refrigerator can be prevented from escaping to the outside through the drainage basin.

In this drainage basin, a bracket is fixedly installed on the outer periphery of the main body of the drainage basin, and a level adjusting bolt for adjusting the level height of the drainage basin is attached to the bracket. By changing the height, you can easily set the floor level.

Further, since the drainage pipe is directly attached to the bottom drainage port of the water storage section or the drainage port is formed laterally on the outer peripheral wall of the water storage section, the drainage level can be kept shallow.

The refrigerator drainage basin 10 is a drainage basin of a type provided with a horizontal drainage port, and includes a drainage basin main body 6 having an upper opening and a detachable lock at the opening end of the main body. It comprises a trash removing basket 7 to be housed and an upper lid 8 with a water passage hole which covers the opening of the drainage basin body 6.

The drainage basin body 6 is integrally formed with a wide level cover 61 on the outer periphery of the open upper portion, a water storage portion 62 is formed on the inner lower portion, and a stainless steel screw-in pipe joint is provided at one location of the outer peripheral wall 64. A drainage port 63 formed by welding is provided. The drain port 63 is connected to the drain pipe 52 on the downstream side.

On the outside of the outer peripheral wall of the drainage basin body 6, brackets 65 projecting horizontally are fixedly provided on three surfaces excluding the attachment surface of the drainage port 63, and the bracket 65 has a high level of the drainage basin. A level adjusting bolt 66 for adjusting the height is attached. The level adjusting bolt 66 is screwed from below to a nut 67 fixed to the bracket 65, supports the drainage basin body 6, and the rotation allows the level height of the drainage basin body 6 to be easily adjusted.

A trap portion T is formed in the water storage portion 62 formed in the lower inside of the drainage basin body 6 in the vicinity of a drainage port 63 communicating with the drainage pipe 52 on the downstream side. The trap portion T prevents leakage of odor from the downstream side, and conversely prevents escape of cold air from the refrigerator B. A plate body having a predetermined height is erected from the bottom portion 6a of the drainage basin body 6 to store water. It is formed by a wall portion 68 that keeps the drainage of the portion 62 at a constant height, and a trap plate 69 that is provided so that its lower edge is immersed in the drainage that is kept at a constant height by the wall portion 68. .

The trap plate 69 is formed by bending a single flat plate from approximately the center to form an L-shaped cross section, and a horizontal piece 69a serving as an upper cover of the trap portion T closes an opening above the wall portion. In this way, it is removably attached to the drainage basin body 6 with screws or the like, and both side edges of the vertical piece 69b are brought into close contact with the inner peripheral wall of the main body, and the lower edges are immersed in the drainage as described above. There is. Therefore, the odor from the downstream side does not leak to the drain basin opening side due to the trap plate 69 and the stored drainage, while the cool air from the refrigerator side does not escape to the outside (drain pipe) through the drain basin. Has been done. Since the trap plate 69 is attached to the drainage tank main body 6 with a screw or the like so as to be attachable and detachable, the inside of the trap portion T can be easily cleaned by removing the screw or the like.

A plurality of locking pieces 70 are fixed to the opening end surrounded by the wall portion 68 of the drainage basin body 6 and the vertical piece 69 b of the trap plate 69. The upper edge 72 of the dust collecting car 7 formed in a wide manner is locked, and the dust collecting car 7 is detachably accommodated in the main body 6.

The dust-removing basket 7 housed in the drainage basin body 6 is open at the upper side, and a large number of drainage holes 71 are formed in the bottom plate and the peripheral wall. Therefore, the dust in the wastewater that has entered from above is removed by the waste-removing basket 7, and the wastewater containing no dust is stored in the water storage section 62. By removing the dust-removing basket, the water storage section 62 can be easily cleaned. A handle 73 made of a bar is laid across the upper opening of the dust-removing basket 7 to facilitate the removal and attachment of the basket 7.

The upper lid 8 that covers the upper opening of the drainage basin body 6 is formed by forming a large number of water passage holes 81 on a single flat plate. By making the flat plate shape, it is possible to reduce the weight and facilitate daily cleaning. I have to. Then, the drainage that has followed the floor surface is introduced into the drainage basin body 6 through the large number of water passage holes 81. In addition, the outer peripheral edge 82 of the upper lid 8 is bent in order to increase the strength.

Then, the drainage basin 10 configured as described above is installed on the floor surface of the refrigerator B adjacent to the work room or the like, as shown in detail in FIG.

That is, the drainage basin body 6 is placed on the earth concrete 51, and the level of the drainage basin body 6 is adjusted and positioned by the level adjusting bolt 66. Then, after the drainage port 63 that is laid out sideways is connected to the drainage pipe 52, the heat insulating foaming agent 53 is filled into the outer periphery of the main body 6 to such an extent that the level adjusting bolt 66 is buried therein. Thereafter, the mortar 54 is used for finishing, and the drainage basin body 6 is installed in the refrigerator B.

Since the present invention can be constructed by such a procedure, the labor of floor construction can be greatly reduced and the floor level can be easily set by mounting a plurality of level adjusting bolts.

In the drainage basin 10 of the present embodiment thus installed, the drainage in the refrigerator is discharged to the sewage side along the following route.

The drainage that has flowed down from the water passage hole 81 of the upper lid 8 along the floor surface, flows from the upper opening of the drainage basin body 6 into the inside of the dust removing basket 7, and passes through the drainage hole 71 formed in the basket. And then flows to the bottom of the drainage basin body 6. Therefore, the dust contained in the wastewater is removed by the waste-removal basket 7, and the wastewater passing through the basket 7 flows down to the water storage section 62 and is collected.

When the water level in the water storage section 62 increases and reaches the upper edge of the wall section 68 standing upright from the bottom of the water storage section 62, the drainage overflows the upper edge and drains downstream from the drain port 63. It flows into the pipe 52.

As described above, since the drainage of the water storage section 62 overflows the wall 68 and flows downstream, a certain amount of drainage is stored in the water storage section 62, and the trap plate allows the drainage basin body to be stored. Since it is cut off from the upper opening side of 6, the odor generated on the downstream side can be prevented from flowing above the drainage basin 10 by the water sealing action of the stored water. On the other hand, the cold air in the refrigerator B does not leak from the drainage container 10 to the outside through the drainage pipe 52 and the like.

Further, since the drainage port 63 communicating with the drainage pipe 52 is formed on the outer peripheral wall 64 of the water storage portion 62 to be laterally exposed, the drainage level can be kept shallow. Therefore, the drainage basin 10 of the present embodiment requires less digging work, speeds up the installation work, and simplifies the chiseling work even in the case of a short-term renovation work. it can.

Further, by mounting the level adjusting bolt, the floor level can be easily set, and the floor construction can be performed easily.

[Effect of the invention]

 As explained above, the refrigerator drainage basin of the present invention has a drainage basin body having an upper opening, and a drainage hole detachably retained at the opening end of the body and accommodated in the body. This is a drainage basin that is composed of a garbage collection basket and an upper lid that has a water passage hole that covers the opening of the drainage basin body, has a trap structure inside, and connects a drainage pipe directly to the outer peripheral wall. Since there is no need to install a concrete pit in the hall or to finish the mortar with an inclined surface at the bottom of the hall, and because the drainage level can be made shallower, there is less digging work, and the installation work is done. In addition to being able to quickly perform the repair work, even in the case of renovation work in a short period of time, the chiseling work has been simplified and it is now possible to respond sufficiently. In particular, horizontal drainage pipes can make the drainage level extremely shallow. In addition, the trap structure can prevent odor leakage and cold air escape.

Furthermore, since the bracket is fixed to the outer side of the outer peripheral wall of the drainage basin body, and the level adjusting bolt for adjusting the level height of the drainage basin is attached to the bracket, the floor level can be easily set. It is now possible to do floor work easily.
