Thereby, the cooling unit 20 is attached to a fixed position.

  In the storage chamber 15 on the right side of the cabinet, the trays T can be stored in a plurality of stages (up to 5 stages) that are taken in and out from the front. Examples of the tray T include a baking top plate Ta (see FIG. 15) and a hotel pan Tb (see FIG. 16). Therefore, a pair of tray receivers 80 are attached to the front plate 35A of the fan case 35 and the right side wall 15B of the storage chamber 15 so as to face each other on the left and right sides of the storage chamber 15. .

The tray receiver 80 is formed in the shape shown in FIGS. 13 and 14 using a wire material such as a stainless steel wire as a raw material.
Specifically, a pair of left and right vertical bars 81 arranged at a predetermined interval are provided, and attachment rings 82 each having a slightly long hexagonal shape are formed at the upper and lower ends of each vertical bar 81. Between the two vertical bars 81, mounting bars 83 are passed over five stages at a constant pitch.
Each mounting rod 83 basically has a U-shape that is bent at both ends at right angles in the same direction, and a mounting portion 85 is bent upward or downward from the tip of the bent portion 84. More specifically, the two ends of the wire rod formed into a rectangular frame shape are bent at right angles so that two sets of two mounting rods 83 are integrally provided, and both ends of the wire rod are simply bent. One thing is provided. In any case, each mounting bar 83 is passed between the vertical bars 81, and the attachment portions 85 at both ends are brought into contact with the outer surface of the vertical bar 81 and fixed by welding.
Here, as shown in FIG. 14, the upper mounting ring 82 is in a position protruding above the uppermost mounting rod 83, while the lower mounting ring 82 is the lowermost mounting rod 83. In other words, the tray receiver 80 is asymmetric in the vertical direction.

On the other hand, fixtures 87 are attached to the front plate 35 </ b> A of the fan case 35 and the right side wall 15 </ b> B of the storage chamber 15 in the cooling unit 20 at four corresponding locations, respectively. Each tray receiver 80 is detachably attached in a form facing the left and right side surfaces of the storage chamber 15 by hooking the attachment rings 82 at the four corners to the corresponding attachments 87.
As described above, the tray receiver 80 is formed asymmetrically up and down, and is selectively used by being inverted upside down when applying the baking top plate Ta as the tray T and when applying the hotel pan Tb. .

  That is, when using the bakery top plate Ta, the tray receiver 80 is mounted in the orientation shown in FIG. In that case, as shown in FIG. 15, the space between the mounting bar 83 located at the uppermost stage in the tray receiver 80 and the ceiling wall 15 </ b> C of the storage chamber 15 is made large. The bakery top plate Ta is loaded and unloaded from the front while the left and right side edges of the bottom surface are placed on the mounting bars 83 facing each other at the same step, and a large space is provided on the ceiling side as described above. Therefore, it is useful when the baking top plate Ta is stored in all five stages.

On the other hand, when the hotel pan Tb is used, the tray receiver 80 is mounted in an upside down direction with respect to FIG. In that case, as shown in FIG. 16, the space between the mounting rod 83 located at the lowest stage in the tray receiver 80 and the bottom wall 15 </ b> D of the storage chamber 15 is large. The hotel pan Tb is put in and out from the front in the same manner while the left and right flanges are placed on the mounting rod 83 facing each other in the same step. The large space on the bottom wall 15D side as described above is useful when the hotel pan Tb is stored in all five stages.
It is also possible to mount the tray receiver 80 in any direction up and down and store the bakery top plate Ta and the hotel pan Tb in a mixed form.

  Finally, the structure of the machine room 90 will be briefly described. A front panel 91 is detachably attached to the front surface of the machine room 90. As shown in FIG. 1, an intake port 92 is formed in a substantially 3/4 region on the left side of the front panel 91. A refrigeration unit 93 is installed inside the machine room 90. A condenser 94 (a chain line in FIG. 2) equipped with a condenser fan 94A is provided immediately after the intake port 92, and a compressor 95 is provided behind the condenser 94. Is placed on a mounting table 96 that can be pulled out. The refrigeration apparatus 93 and the cooler 21 provided in the cooling unit 20 are circulated and connected by a refrigerant pipe 97 to constitute a refrigeration circuit. Exhaust ports 98 for exhaust heat and the like are formed on the back surface and the left and right side surfaces of the machine room 90.

Then, the effect | action of this embodiment is demonstrated. The rapid cooling box is used for cooling food after cooking in a short time.
The cooked food is placed in the tray T, and the tray T is received in the storage chamber 15 over a maximum of five levels while being received by the mounting bars 83 at the same level of the left and right tray receivers 80. When the storage of the tray T is completed, the heat insulating door 13 is closed. When the cooling operation is performed in this state, that is, when the refrigeration apparatus 93 (compressor 95) and the cooling fan 22 are operated, the air in the storage chamber 15 is sucked into the suction port of the fan case 35 as shown by the arrow in FIG. Cold air is drawn into the cooling unit 20 through 36A and passes through the cooler 21, and the cold air blown out to the back side of the cooling unit 20 hits the left side wall 16B in the refrigerator and is divided into the front and back. Then, after circulating around the front side and the back side of the cooling unit 20, a circulation flow is generated such that the cooling unit 20 is sent into the storage chamber 15, whereby the food in the tray T is rapidly cooled.

During this time, the condenser fan 94A disposed on the rear surface of the condenser 94 is driven together so that outside air is sucked from the air inlet 92 of the front panel 91 of the machine room 90 and passes through the condenser 94. The condenser 94 is cooled, and the exhaust heat after cooling is exhausted to the outside through an exhaust port 98 provided on the rear surface or side surface of the machine room 90.
When the predetermined time has elapsed, the cooling operation is stopped, and after the heat insulating door 13 is opened, the tray T is taken out of the cabinet.

  When cleaning the inside of the main body 10, tap water is applied to the wall surface in the warehouse with a hose or the like. At this time, when the inside of the cooling unit 20 is washed with water, both tray receivers 80 are removed and taken out of the cabinet, then the locking device 39 of the cooling unit 20 is removed, and as shown in FIG. Is opened toward the back wall 15A. If it does so, since it will be in the state by which the cooler 21 and the cooling fan 22 in the cooler cover 25 were open | released in the store | warehouse | chamber, it can wash | clean by pouring water directly.

  Here, the cooler 21 has a structure in which the front edge and the rear edge on the front side are covered with the bent plate 26A of the front cover plate 26 and the auxiliary plate 28 of the back cover plate 27, respectively, so that it is difficult to splash water. It has become. However, the front cover plate 26 has a plurality of through holes 40 aligned and opened over almost the entire surface, while the base portion of the front end portion facing the front of the auxiliary plate 28 provided on the back cover plate 27. Since the slit 42 is opened over almost the entire height, if water is poured toward the front cover plate 26, the water is also hung on the near end of the cooler 21 through the through hole 40. In addition, if water is poured from the storage chamber 15 toward the auxiliary plate 28, it is also hung on the back end of the cooler 21 through the slit 42.

  In addition, when washing with water in the chamber as described above, there is a possibility that a part of the drainage after the washing will fall on the spacer plate 50. After passing through the water draining groove 60 opened in the spacer plate 50 and falling to the left flange 72, it is dropped directly on the left edge in the drain pan 70 and received. What is necessary is just to discard the waste_water | drain collected in the drain pan 70 out of the store | warehouse | chamber with the defrost water collected at the time of a defrost operation.

As described above, in the present embodiment, in the cooler cover 25 mounted so as to cover the cooler 21, the front cover plate 26 has a plurality of through holes 40 aligned and opened over substantially the entire surface. On the other hand, a slit 42 is opened over almost the entire height at the base portion of the tip portion 28A facing the front side of the auxiliary plate 28 provided on the back cover plate 27.
Therefore, if water is poured from the front side toward the front cover plate 26, the water is also hung on the front side end portion of the cooler 21 through the through hole 40, and the storage chamber 15 is directed toward the auxiliary plate 28. If water is poured from the side, it passes through the slit 42 and is also hung on the back end of the cooler 21. As a result, both the front side and back side end portions of the cooler 21 can be sufficiently washed with water.
