However, when the structure is such that a cooling unit is provided inside the storage chamber as in the cooling storage described in Patent Document 1, there is a portion that becomes a blind spot of the injection portion, and the injection is performed. There is a risk that the washed water will not flow sufficiently and the cleaning of the storage chamber will be insufficient.

The present invention has been made in view of such circumstances, and an object of the present invention is to enhance the cleaning power of a cleaning device in a cooling storage facility provided with a cooling unit in a storage chamber.

In order to solve the above problems, the cooling storage of the present invention is used.
A box-shaped storage body having a storage chamber, a cooling unit provided in the storage chamber and including at least a cooler to cool the storage chamber, and a cooling unit provided in the storage chamber to inject water. A cooling storage including a cleaning device for cleaning the storage chamber.
The cleaning device

A plurality of discharge nozzles provided on the cooler facing extension portion at intervals in the extension direction and injecting cleaning water toward the cooler at least in a range extending in the extension direction.
It is characterized by being equipped with.

Conventionally, for cleaning the cooler (evaporator), the water pipes are arranged in a serpentine or parallel manner facing the side surface of the cooler, and the water is washed from the injection holes formed in the water pipes. A configuration was adopted in which the water was sprayed and washed. However, in such a configuration, the range to be cleaned by the cleaning water injected from each injection hole is narrow, and there is a risk that the cleaning of the cooler will be insufficient. On the other hand, according to the cooling storage having this configuration, the upper end of the side surface of the cooler can be sprayed with cleaning water without gaps by a plurality of discharge nozzles capable of injecting a wide range in the direction along the upper end thereof. By flowing the washing water downward, the cooler can be sufficiently washed to the lower side. The discharge nozzles are supposed to inject cleaning water in a fan shape (wide-angle), for example, and by making the injection ranges of adjacent discharge nozzles partially overlap, cleaning is performed without a gap at the upper end of the side surface of the cooler. Can be sprayed with water. By the way, the cooling storage of this configuration may be configured to include a discharge nozzle that injects cleaning water toward at least the upper end of the side surface of the cooler, and also injects cleaning water below the upper end of the cooler. The configuration may be provided with an injection hole and a discharge nozzle. However, a sufficient cleaning effect can be obtained only by injecting cleaning water from a plurality of discharge nozzles provided in the extension portion facing the cooler.

In the above configuration, the cooling unit includes a circulation fan provided horizontally side by side with respect to the cooler to circulate air in the storage chamber.
The water pipe is arranged between the cooler and the circulation fan, is provided at intervals in the vertical direction from each other, and has a plurality of extending portions, each of which is extended in the horizontal direction.
In the plurality of extending portions, a plurality of injection holes for opening to the circulation fan side and injecting water toward the circulation fan are formed.
The discharge nozzle is provided only in the uppermost extension portion among the plurality of extension portions, and the uppermost extension portion functions as the cooler facing extension portion. It is possible to configure the extension portion other than the upper extension portion so that the washing water is not sprayed toward the cooler.

In the cooling storage of this configuration, the water pipe is supposed to clean both the cooler and the circulation fan. And, as described above, the cleaning of the cooler according to the above configuration can obtain a sufficient cleaning effect only by spraying the cleaning water on the upper end of the side surface of the cooler. No discharge nozzle is provided other than the uppermost extension part (cooler facing extension part), and the cooler can be efficiently cleaned with the minimum necessary discharge nozzles. There is. In other words, it is possible to suppress the increase in cost and the increase in manufacturing tasks due to the increase in the number of discharge nozzles.

Further, in the above configuration, the cooling unit includes at least a housing for accommodating the cooler, and the cleaning device is provided on the ceiling surface of the storage chamber and has cleaning water on the inner surface of the storage chamber and the outer surface of the housing. The housing may have a ceiling-side injection portion for injecting water, and the housing may be configured to have an upright portion erected along a part of the outer peripheral edge of the upper surface.

The housing of the cooling unit has a surface on which the cleaning water jetted from the ceiling-side injection portion does not easily flow due to the positional relationship with the ceiling-side injection portion. In the cooling storage having this configuration, the washing water collected on the upper surface of the housing can be allowed to flow down from the portion where the standing portion is not formed, and the washing water flowing to the surface where the washing water is difficult to flow can be increased. That is, according to the cooling storage having this configuration, it is possible to increase the amount of cleaning water flowing to the surface of the ceiling-side injection portion in the housing of the cooling unit, which is a blind spot, and it is possible to increase the cleaning power of the cooling unit.

Further, in the above configuration, the housing has a cooler case having an opening formed on its upper surface for accommodating the cooler and inserting a refrigerant pipe connected to the cooler, and the cooler in the refrigerant pipe. It is configured to include a refrigerant pipe cover that covers a portion extending to the upper side of the case from above, and the standing portion may be configured to be formed on the upper surface of the refrigerant pipe cover.

The cooling storage of this configuration is limited in the configuration of the cooling unit and the configuration of the housing for accommodating the cooling unit. In the cooling storage of this configuration, it is desirable that the refrigerant pipe cover has a part of the outer edge on the upper surface thereof located above the upper surface of the cooler case, in other words, overlaps in the vertical direction. .. With such a configuration, the cleaning water can flow down from a part of the refrigerant pipe cover to the upper surface of the cooler case, so that the cleaning water can flow from the upper surface of the cooler case toward the outer surface. , The cleaning power of the outer surface of the cooler case can be enhanced.

Further, in the above configuration, the cooler case may have an opening edge erecting portion formed along the opening edge of the opening.

In the cooling storage having this configuration, the opening edge erection portion can prevent the washing water on the cooler case from flowing down from the opening into the inside of the cooler case. That is, the wash water on the cooler case can flow down along the outer surface of the cooler case. As described above, since the cleaning of the cooler is sufficiently performed by the above configuration, the cleaning water collected on the cooler case is allowed to flow to the outer surface of the cooler case, and the cleaning flows to the outer surface of the cooler case. By increasing the amount of water, the cleaning power of the outer surface of the cooler case can be enhanced.

Further, in the above configuration, the cleaning device is fixed to a detergent tray having a box-shaped opening on one side and capable of containing detergent, and a vertical wall portion having a vertical wall-like wall surface in the storage chamber, and the detergent tray. It is configured to include a tray holder that rotatably holds the detergent, and is provided with a detergent charging mechanism for charging detergent at the time of cleaning by the cleaning device.
The detergent tray has an extension formed so as to extend from its opening edge to the one side.
In the standing wall portion, a standing wall portion injection hole for injecting cleaning water by the cleaning device is formed.
The detergent injection mechanism is
Before cleaning, the detergent tray is held in a state of being opened upward, and in that state, the vertical wall injection hole is closed by the extending portion.
When cleaning is started by the cleaning device, the cleaning water sprayed from the vertical wall injection hole hits the extending portion, the detergent tray rotates, and the detergent is poured so as to drop the detergent from the detergent tray. It is configured to be
The detergent tray is rotated by the washing water sprayed from the vertical wall injection hole, and then the extending portion abuts on the tray holder and is stopped in an inclined state. The extension portion may be configured to have an insertion portion through which the washing water jetted from the vertical wall portion injection hole is inserted.

In the cooling storage having this configuration, if the detergent is put in the detergent tray, the detergent can be put in by utilizing the injection of the washing water at the time of washing. Since the extension portion of the detergent tray comes into contact with the tray holder in the cooling storage having this configuration, it is easy to return to the original state after cleaning. Therefore, conventionally, during cleaning, the extension portion of the detergent tray may hit the cleaning water sprayed from the injection hole of the vertical wall portion and diffuse, but the cooling storage having this configuration is provided in the extension portion. Since the insertion portion is formed, it is possible to avoid the situation where the cleaning water hits the extending portion of the detergent tray and diffuses as described above, and efficiently cleans the cleaning water sprayed from the vertical wall injection hole. Can be used for.

According to the present invention, in a cooling storage provided with a cooling unit in the storage chamber, the cleaning power of the cleaning device can be enhanced.

It is also possible to make it possible to inject water in a range that is flat in the direction.

Further, as shown in FIG. 12, a plurality of injection holes 62 capable of injecting water toward the internal fan 36 are formed on the generally right side of the pipe 60. More specifically, the injection hole 62 is provided not only in the plurality of extending portions 60A1, 60A2, 60A3, 60A4, but also in the connecting portion 60B extending in the vertical direction and connecting between the extending portions 60A1, 60A2, 60A3, 60A4. , Is formed. On the other hand, as shown in FIG. 13, on the left side of the pipe 60, neither a nozzle for injecting water nor an injection hole is provided in addition to the above-mentioned four discharge nozzles 61. That is, the rapid cooling chamber 10 has a configuration in which the cooler 35 can be efficiently cleaned with only the minimum necessary discharge nozzle 61. In other words, the rapid cooling chamber 10 suppresses an increase in cost and an increase in manufacturing tasks due to an increase in the number of discharge nozzles 61.

Further, as shown in FIGS. 14 and 16, the extending portion 60A4 at the lowermost stage of the pipe 60 is provided with a nozzle 63 extending toward the right side. The nozzle 63 also constitutes a detergent charging mechanism 42. The detergent charging mechanism 42 will be described in detail below with reference to FIGS. 17 to 20.

The detergent charging mechanism 42 is provided on the right side wall surface 37B1 of the case cover 37B as a vertical wall portion in the storage chamber 15. As described above, the detergent charging mechanism 42 is mainly composed of the detergent tray 70 and the tray holder 71. The tray holder 71 is a generally frame-shaped member that opens in the vertical direction, and holds the detergent tray 70 inside itself. More specifically, the detergent tray 70 is provided with a shaft portion 72 on each of the front wall surface portion and the rear side wall surface portion in the storage chamber 15. On the other hand, the tray holder 71 rotatably holds the shaft portion 72 of the detergent tray 70 in the through holes 71A formed in each of the front wall surface portion and the rear wall surface portion, thereby causing the detergent tray 70 to rotate. The shaft portion 72 is rotatably held around the center of rotation. That is, the tray holder 71 rotatably holds the detergent tray 70 around an axis extending in the front-rear direction parallel to the right side wall surface 37B1 of the case cover 37B.

The detergent tray 70 is supposed to have an extension portion 73 whose left wall surface portion extends upward. The extending portion 73 includes a facing wall portion 73A facing the right side wall surface 37B1 of the case cover 37B, and a flange portion 73B protruding from a part (front side portion) of the upper end of the facing wall portion 73A toward the right side wall surface 37B1. Consists of. As shown in FIGS. 17 and 18, the detergent tray 70 is usually provided with an facing wall portion 73A erected, and a flange portion 73B is a wall surface portion on the left side of the tray holder 71 (on the right side wall surface 37B1 side of the case cover 37B). By being in a state of leaning against a certain left wall surface portion 71B, it is possible to open upward and put detergent in it.

Further, a through hole 37C is formed in the right side wall surface 37B1 of the case cover 37B, and the nozzle 63 of the above-mentioned cooling unit side injection unit 46 provided in the case 37 is arranged to face the through hole 37C in the through hole 37C. ing. In the above-mentioned normal state, the detergent tray 70 has a facing wall portion 73A standing in front of the through hole 37C (right side, cart arrangement space 15A side), that is, a through hole 37C which is a standing wall portion injection hole. Is in a closed state.

Then, when water is sprayed from the nozzle 63 during cleaning of the inside of the storage chamber 15, the sprayed water (arrow line L1) hits the facing wall portion 73A of the detergent tray 70, as shown in FIG. 19, and the detergent tray The 70 rotates about the shaft portion 72. That is, the detergent charging mechanism 42 rotates the detergent tray 70 by utilizing the injection of the washing water so that the detergent contained in the detergent tray 70 is dropped onto the bottom wall portion 15F, and the detergent is charged. It is configured to do. As described above, the detergent that has fallen on the bottom wall portion 15F mixes with the water on the bottom wall portion 15F (water jetted from the ceiling side injection unit 45 or the cooling unit side injection unit 46). It collects in the tank 41 through the drain port 15G. As a result, by operating the pump 43, the water mixed with the detergent can be circulated between the tank 41 and the ceiling side injection unit 45 (or the cooling unit side injection unit 46).

Further, when the detergent tray 70 is rotated by the jetted water, the extending portion 73 comes into contact with the upper end of the right wall surface portion 71C, which is the right wall surface portion of the tray holder 71, and the rotation is stopped. It can be stopped in a tilted state (a state rotated by almost 90 degrees). Therefore, it is easy to return the detergent tray 70 to its original position after cleaning. However, when the detergent tray 70 is in contact with the right wall surface portion 71C of the tray holder 71, the flange portion 73B is erected as shown in FIGS. 19 and 20. The flange portion 73B overlaps with the water jetted from the nozzle 63 in the height direction, but in the present embodiment, the flange portion 73B is formed only on the front side portion at the upper end of the facing wall portion 73A. It does not overlap in the front-back direction. That is, in the present embodiment, the portion (rear side portion) where the flange portion 73B is not formed at the upper end of the facing wall portion 73A is the insertion portion 73C through which the water jetted from the nozzle 63 is inserted. ..

Due to such a configuration, in the rapid cooling chamber 10, the water ejected from the nozzle 63 does not hit the detergent tray 70 (specifically, the extension portion 73) and diffuse, and the water is ejected from the nozzle 63. The water can be sprayed onto the side wall on the right side of the storage chamber 15, and can be efficiently used for cleaning.

Next, cleaning of the outer surface of the cooling unit 16 will be described in detail with reference to FIGS. 21 to 24. First, as shown in FIG. 21, in detail, the case 37 has an opening 80 formed on the front side of the upper surface of the case body 37A, and the opening 80 is connected to two coolers 35. The refrigerant pipe 38 is inserted. The opening 80 is provided with a guide 81 as an opening edge erection portion that stands along the opening edge.

The refrigerant pipe 38 extending from the case 37 is bent above the opening 80 and extends rearward. As shown in FIGS. 12, 22, and 23, the portion of the refrigerant pipe 38 extending above the case 37 is covered from above by the refrigerant pipe cover 82. However, in the refrigerant pipe cover 82, the right wall surface portion 82A located on the right side of the refrigerant pipe 38 is provided with a gap between the right wall surface portion 82A and the upper surface of the case 37, and is injected from the ceiling side injection portion 45 through the gap. It is configured so that water also enters the upper surface side of the case 37. On the other hand, the left wall surface portion of the refrigerant pipe cover 82 is connected to the upper end of the guide 83 (see FIG. 21) erected along the left outer edge on the upper surface of the case 37, and enters the upper surface side of the case 37. The washing water is not allowed to flow down to the left side of the case 37. Further, as shown in FIG. 21, a return portion 84 projecting upward from the case body 37A is provided on the upper surface of the case cover 37B, and the water collected on the upper side of the case body 37A is collected from the case cover 37B. It is also difficult to flow to the side.

Further, as shown in FIGS. 22 and 23, the refrigerant pipe cover 82 is provided with a guide 85 that stands along the outer edge on the left side of the upper surface portion 82B. That is, the water injected from the ceiling-side injection portion 45 and collected on the upper surface portion 82B of the refrigerant pipe cover 82 is prevented from flowing down to the left wall surface portion by the guide 85. The rapid cooling cabinet 10 includes a case 37 as a cooler case for accommodating the cooler 35 and the internal fan 36, and a housing 90 for accommodating the cooling unit 16 including a refrigerant pipe cover 82. The guide 85 provided on the upper surface of the refrigerant pipe cover 82 functions as an upright portion that stands along a part of the outer peripheral edge on the upper surface of the housing 90.

Further, as shown in FIG. 24, in the refrigerant pipe cover 82, the front surface portion 82C located on the front side of the refrigerant pipe 38 is located in front of the front surface 37A1 of the case body 37A, and the front surface portion 82C of the refrigerant pipe cover 82. The lower side of the space between the case body 37A and the front surface 37A1 of the case body 37A is not blocked except for the mounting portion 82D for mounting the refrigerant pipe cover 82 to the case body 37A, and the refrigerant pipe cover 82 is opened downward. There is.

From the above configuration, in the rapid cooling chamber 10, when the cleaning water is injected from the ceiling side injection unit 45 during cleaning, the cleaning water is collected on the upper side of the refrigerant pipe cover 82 and the upper side of the case 37. By the way, since the nozzle pipes 45B and 45C of the ceiling side injection unit 45 rotate from the rear to the front on the cooling unit 16 side, the washing water on the refrigerant pipe cover 82 flows from the rear to the front. Cheap. Then, as shown in FIGS. 22 and 23, the washing water collected on the refrigerant pipe cover 82 does not flow down to the left side of the refrigerant pipe cover 82 due to the presence of the guide 85, and is on the front side of the refrigerant pipe cover 82. Or it will flow down from the right side. The left-right dimension of the refrigerant pipe cover 82 is smaller than the left-right dimension of the case body 37A, and the right wall surface portion 82A is located above the upper surface of the case body 37A. More specifically, it is located on the left side of the edge of the return portion 84. As a result, the washing water flowing down from the right side of the refrigerant pipe cover 82 falls on the upper surface of the case body 37A.

The cleaning water that has flowed down from the refrigerant pipe cover 82 or the cleaning water that has directly entered the upper side of the case body 37A from below the right wall surface portion 82A of the refrigerant pipe cover 82 does not flow to the left side by the guide 83, and the return portion. The 84 makes it difficult for the washing water to flow to the right, and a large amount of washing water flows forward and flows down the front surface 37A1 of the case body 37A from the gap with the front surface portion 82C of the refrigerant pipe cover 82. .. Furthermore, since the guide 81 makes it difficult for the washing water to flow down from the opening 80, more washing water can flow down to the front surface 37A1 of the case body 37A. That is, the rapid cooling chamber 10 increases the amount of washing water flowing to the front surface of the housing 90 (particularly, the front surface 37A1 of the case body 37A), which is a blind spot of the ceiling-side injection unit 45 that rotates from the rear to the front. The cleaning power of the outer surface (housing 90) of the cooling unit 16 is high.

<Modification example>

In the detergent tray 70, as shown by solid lines in FIGS. 27 and 28, the facing wall portion 110A is erected, and the flange portion 110B leans against the back wall portion 111 which is the wall surface portion on the rear side of the tray holder 103. By being in the hung state, it becomes possible to open upward and put detergent in it.

On the other hand, a through hole 120 is formed in the front surface (standing wall portion) 37B2 of the case cover 37B, and the nozzle 121 of the cooling unit side injection portion provided in the case 37 is arranged to face the through hole 120. ing. In the above-mentioned normal state, the detergent tray 102 is in a state in which the facing wall portion 110A stands in front of the through hole 120, that is, in a state in which the through hole 120, which is the vertical wall portion injection hole, is closed. When water is sprayed from the nozzle 12 during cleaning of the storage chamber 15, the sprayed water hits the facing wall portion 110A of the detergent tray 102, and the detergent tray 102 rotates about the shaft portion 122. It is configured to drop the detergent.

However, in the above embodiment, the tray holder 71 also opens downward, but in this modification, the tray holder 103 has a bottom surface portion 130. More specifically, as shown in FIGS. 28 and 29, the bottom surface 130 of the tray holder 103 has an inclined surface shape that descends toward the rear (front surface 37B2 of the case cover 37B which is a vertical wall portion). A notch 130A that opens downward is formed at the rear end of the bottom surface portion 130. Therefore, the detergent charging mechanism 101 drops the detergent from the detergent tray 102 onto the tray holder 103, lowers it along the bottom surface 130 of the tray holder 103, and drops it from the notch 130A onto the bottom wall portion 15F. Therefore, it is configured to add detergent.

If the detergent charging mechanism 101 provides the detergent charging mechanism 42 of the above embodiment on the front surface 37B2 of the case cover 37B, the detergent will fall in the vicinity of the doors 12 and 17A. As shown in FIG. 26, the detergent charging mechanism 101 allows the detergent to be dropped from the vicinity of the front surface 37B2 of the case cover 37B and put into the recess of the bottom wall portion 15F.
