  However, in the above-mentioned publication, warm side dishes such as boiled foods, cold side dishes such as salads, and cold drinks such as tea are displayed in different showcases.

  In addition to buying hot dishes, cold dishes and cold drinks together, you will need to look at each case, and if you forget to buy, you will need to return to the showcase. Since it is not displayed on the display shelf together, it is not possible to stimulate the buyer's willingness to sell, and therefore the improvement in sales is low, so improvement is desired.

  The present invention has been made in order to solve the above-described problems. A warm storage room and a cold storage room are provided in a showcase, and a hot dish, a cold dish, and a cold beverage can be purchased at a time in one showcase. The purpose is to provide such a showcase.

The showcase of the present invention is a showcase having a refrigerator compartment, a refrigerator compartment, and a cooling unit for cooling the refrigerator compartment in the heat insulating wall. A partition shelf for partitioning the refrigerator compartment and the warm compartment is provided, and a discharge gas pipe from a lamp heater and a compressor built in a showcase is provided in the partition shelf.

The showcase of the invention of claim 2 is characterized in that, in the above invention, a drawer is provided below the lamp heater and the discharge gas pipe in the partition shelf.

  The showcase of the invention of claim 3 is characterized in that, in claim 1, the lamp heater is energized when the compressor is stopped.

The showcase of the invention of claim 4 is characterized in that, in the invention of claim 1, a slide door is provided in front of the warming room.

  According to the showcase of claim 1 of the present invention, in a showcase comprising a refrigerator compartment, a refrigerator compartment, and a cooling unit for cooling the refrigerator compartment in the heat insulating wall, the refrigerator below the showcase, Is provided with a partition shelf for partitioning the refrigerator compartment from the refrigerator compartment, and a discharge gas pipe from a lamp heater and a compressor built in a showcase is provided in the partition shelf. Can be cooled and the warming room can be warmed.

  As a result, it has become possible to display items that have been sold in separate showcases, such as hot and cold prepared foods and cold beverages, in a single showcase. It is effective.

  In addition, by providing a drawer below the lamp heater and discharge gas pipe in the partition shelf, the inside of the drawer is not heated and cooled. Since packs and trays for storing hash, tongs, and side dishes can be stored, it is possible to select a product immediately when it is desired to purchase.

  Further, when the compressor is stopped, the lamp heater is energized, and even if the compressor is stopped, the lamp heater provided on the partition shelf is energized, so that the warming room can be heated and kept warm. .

  Furthermore, by providing a sliding door in front of the warming room, it is possible to suppress the release of heat from the warming room to the outside, and to prevent the entry of dust and dirt from the outside. Out.

It is a longitudinal cross-sectional view of the showcase according to the Example. It is a front view of the showcase according to the Example. It is a refrigerant circuit figure which flows the discharge refrigerant to a warm room. It is an enlarged view of the warming room according to the Example. It is the electrical wiring diagram according to the Example.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a longitudinal sectional view of a showcase 1 as an embodiment to which the present invention is applied. 2 is a front view of a showcase 1 as an embodiment to which the present invention is applied, and FIG. 4 is an enlarged vertical sectional view of the warming room 7.

  The showcase 1 according to the embodiment is a vertical showcase 1, and a heat insulating wall 3 having a U-shaped cross section, and a partition plate 4 is disposed inside the heat insulating wall 3.

  In addition, a warm room 7 is arranged in the upper part of the showcase, and a cold room 8 is arranged in the lower part.

  In the warm room 7 and the cold room 8, display shelves 9a and 9b are provided. Further, a deck pan 10 is attached to the bottom of the refrigerator compartment, and a bottom duct 11 communicating with the duct 2 on the back surface is disposed below the deck pan. A cooler 16 is provided vertically at the lower portion of the duct 2.

  The warm room 7 and the cold room 8 are partitioned by a partition shelf 5, and a sliding drawer 22 is provided at the lower part of the partition shelf 5.

  A bat 20 can be placed on the display shelf 9a and the partition shelf 5 in the warm room 7 so as to be able to display warm prepared food. In addition, inside the slide-type drawer 22, it is possible to store hashes and tongs for purchasing side dishes displayed in the warm room and the cold room, and packs and trays for storing side dishes. It is possible to select a product immediately when you want to.

  In addition, a slide door 21 is provided on the front surface of the warming chamber 7 so that heat in the warming chamber 7 can be prevented from being released to the outside. Intrusion can be suppressed.

  A suction port 24 connected to the bottom duct 11 is arranged at the lower front portion of the refrigerator compartment 8, and air passes through the bottom duct 11, the cooler blower 12, and the cooler 16 from the suction inlet, and is blown out from the cool air outlet 25 into the refrigerator compartment. By passing through the cooler 16, the refrigerator compartment 8 is cooled by the cooled cold air.

  In addition, a lamp heater 18 is provided in the partition shelf 5, and the warming chamber 7 can be heated and kept warm.

FIG. 3 is a refrigerant circuit diagram of the present invention, and FIG. 5 is an electrical wiring diagram of the present invention.

The refrigerant compressed by the compressor 13 is supplied to a discharge gas pipe 19 provided in the partition shelf 5, warms the partition shelf 5, condenses in a part of the condenser 14, and returns to the compressor 13. And compressed again. The recompressed refrigerant condenses in the condenser 14 other than a part of the condenser, passes through the dry core and the solenoid valve capillary tube, cools in the cooler 16, passes through the check valve and the accumulator. And returned to the compressor 13.

  Further, the machine room 6 is provided with a condenser 14 and a condenser blower 15, and the condenser 14 and the compressor are sucked by the condenser blower 15 from the intake port 17 provided on the front surface of the machine room 6. 13 is cooled.

  Moreover, the high temperature refrigerant | coolant which heats the partition shelf 5 is about 40 degreeC-about 90 degree | times, and can fully warm or keep warm in a storage chamber.

With the above refrigerant circuit, cold prepared foods, cold drinks, and the like displayed in the refrigerator compartment 8 are cooled, and warm prepared dishes etc. displayed in the refrigerator compartment 5 are heated or kept warm.

  The compressor 13 is operated to cool the refrigerating chamber 8, and the thermostat 42 is turned on and off by the temperature sensor in the refrigerating chamber 8 and the coil of the magnet switch 43 operates to operate. ing. Even when the compressor 13 is stopped, the warming chamber 7 can be heated or kept warm by energizing the lamp heater 50.

  Moreover, since the bimetal thermo 41 is installed in the electrical wiring through which the high-temperature refrigerant from the compressor 13 passes in order to prevent the partition shelf 5 from overheating, the partition shelf 5 is not heated more than necessary. Moreover, the side dishes etc. displayed in the warm room 7 are not affected.

Further, the drawer 22 is provided below the lamp heater 18 and the discharge gas pipe 19 in the partition 5, and the inside of the drawer 22 is at room temperature without being heated and cooled.
