Description

[Detailed description of the invention] (b) Industrial t) J field The present invention relates to a low temperature showcase equipped with a humidifier.

(b) Prior art Publication No. 50-40365 (JPC, 70B42)
At 4 o'clock, water is poured into the cooler and
The configuration for solving ■ is shown. This configuration has the following drawbacks.

■ The water collection pipe that discharges water to the cooler is placed on the air outlet side of the cooler, so that the remaining water droplets in the water collection pipe generated during defrosting can reach the low temperature immediately after heat exchange in the cooler during cooling. It is cooled by cold air and freezes, and it takes time until the next time to remove one stone.

■ The water discharged into the cooler is drained outside through the drain and cannot be reused.

(C) Object of the Invention The present invention aims to solve the drawbacks of the prior art and to use the water used for removing the cooler to humidify the storage room during cooling.

2) Composition of the Invention A water supply device which is placed under pressure at the air inlet of the cooler to which high-temperature cold air returns after passing through the storage chamber, and which opens a solenoid valve when unregistered and sprinkles water on the cooler to soothe the cooler. and a humidifier, which is disposed on the air outlet side of the cooler and stores water that has passed through the cooler during removal, and evaporates the stored water using a heater during cooling to humidify the storage room. .

(e) Examples of the invention The present invention will be described in detail below based on the drawings.

(1) is a low-temperature showcase for cooling and storing fresh sweets, etc. that require thick humidification, and the Ur heating box (
2), a transparent window (3) placed on the north side of the box (1) and 11, and a two-piece silk transparent door (3) that slides from side to side, placed above the 7th plane of the box. 4) and two transparent walls (5) placed on both the left and right sides of the box.
) (6) and a heat insulating ceiling wall (7) placed between the two side walls and covering the upper edges of the transparent window and the transparent door.
19, and at the same time, on these joint walls, the product +ii at the bottom of ゛C
A storage cabinet (9) with a storage board (8) installed is constructed by one cedar.
l) - A cooling chamber that is shaped by arranging shutter-like rectifying plates (marks) that are spaced apart from each other and that also serves as a partition plate. A water supply device (14) is placed above the air inlet side of the cooler, and a humidifier (14) is placed below the air outlet side of the cooler. As shown by the arrow, the flow is guided from the lower part of the rectifier plate (11) to the storage chamber (9) and flows forward along the surface of the product placement plate (8).
After being folded back C, so-called natural convection is performed from the upper part of the baffle plate (11) and returned to the cooler u21K, and the storage chamber (9) is cooled by this natural convection. In addition, the water supply device includes a water supply pipe (national) that leads water from a water source such as a water supply pipe, and a solenoid valve (1
6), and a nozzle (1η (17)) that is formed at the tip of the water supply pipe and sprays water onto the cooler (12).The humidifier also includes a water supply device (13) during defrosting. ) a container for collecting water sprinkled from the cooler (12) to the cooler (12);
It consists of a heater such as an electric heater that heats and evaporates water stored in this container during cooling.

The steam evaporated by this humidifier is included in the cold air that naturally convects, and humidifies the storage room (9). (4) is a machine room formed below the insulation box (2), which includes a refrigerant compressor (2I) and a condenser (2I), which together with the cooler constitute a refrigeration cycle.
22) etc. are installed.

Figure 5 shows the electric circuit of the low-temperature shiso case (1).
The floor has an AC power supply, (24)04)&ma main switch, (
29 is a timer, (26) is a first thermostat that controls the temperature of the storage room (9), and 29 is a second thermostat that controls the heat generation temperature of the heater (11). A timer motor book, a contact piece i2!l that opens 17M due to the drive of this timer motor, a fixed contact +30) that fixes this contact piece, a cooling contact C31) that the contact piece contacts during cooling, and a The contact for removal from the register that the contact piece touches (
321. The cooling contact includes:
The first thermostat N2B! , a series circuit consisting of a compressor (2I) and a second thermostat) (2n, heater +
A series circuit consisting of 11 is connected in parallel, and a solenoid valve (16) is connected to the discharge contact.

2 When the timer motor (28) is driven and the contact piece is in contact with the cooling contact (31), the cooling operation is started, the compressor 2D makes 7 sounds, and the refrigeration cycle is configured. As a result, the storage chamber (9) is cooled, and the water in the container (18) evaporates due to the heat generated by the heater, thereby humidifying the storage chamber (9). When a predetermined period of time has passed from the start of the cooling operation and the contact wire switches to the defrosting contact 6 hot water, the load-relieving operation begins, and the compressor (zl) and heater (1 and 1 are both de-energized, while the solenoid valve (16) is energized and opened. With this opening, water is sprinkled from the water supply pipe (I5) to the cooler ([hot water), the silk in the cooler Oz gradually melts, and the container U
The water stored in the mark is replaced with a portion of the water that has passed through the cooler (12).

According to the configuration, the water from the water supply device (13) in times of crisis is used to divide the cooler (1z) by 1, thereby reducing the cost of removal from the register, and also humidifying the water used for removing the cooler from the cooler 02. Since the water can be stored in device 04) and used to humidify the storage room (9) during cooling, there is no need to install a new water supply device for the humidifier (I4), and the humidifier Q is used each time H is removed.
Since it is possible to clean the humidifier 04), replace the water in the humidifier, and store new water, it is possible to remove dirt from the humidifier 04) generated during cooling and to maintain a sanitary humidifier 04).
Humidifying device (14) for the next cooling
can prevent water shortages. In addition, since the water supply device (13) is placed at the air inlet of the cooler (121) and is constantly exposed to high-temperature (0°C or higher) return cold air, there is no risk of freezing during cooling, that is, the nozzle ( 17) Even if you switch from unloading operation to cooling operation while water droplets have landed on (17), the water droplets will not freeze and block the nozzle zero force aη, and the next time you defrost, the water will be removed immediately. water can be sprinkled on the cooler Oz.

(F) Effects of the Invention Since the present invention is configured as described above, the effects listed in Th are produced.

■ The humidifier can be kept sanitary by washing the humidifier when defrosting the cooler, and the water used for humidifying the storage room can be stored during cooling, making effective use of water. can be achieved.

■ With Q, the water supply system is placed on the air inlet side of the cooler and is exposed to high-temperature return air. When defrosting, water spraying can be performed at speed 7.
