Description

[Detailed Description of the Invention] The present invention relates to a large-sized showcase for freezing and refrigerating stored items, and particularly relates to an improvement in a drain processing structure.

Oven showcases equipped with refrigeration cycle equipment and used to freeze and refrigerate stored items are often used.

Conventionally, a large showcase of this kind has a pair of machine rooms e, e equipped with a condensing part b, a blower C, a compressor d, etc. at the bottom of the main body a, as shown in Figure 1, and these machine rooms. e
, e, for example, a drain pan g equipped with a heating pipe f that utilizes condensation heat is interposed.

A storage chamber (not shown) is provided above the machine rooms e, e and the drain tray g.

An evaporator, which is a cooler, is installed in the storage room, and drains such as defrosting water are led to the drainage tray g.

In order to fill the drainage tray g with the drain in a very short time, the heating pipe f heats the drain to evaporate it.

By the way, the blowers c and c are arranged in series with the condenser b and the compressor d, and the air blowing direction is parallel to the drain pan g.

Therefore, almost no air from the blower C passes through the drain pan g.

Although wind deflectors are installed, they are not very effective and drain evaporation efficiency is poor.

Furthermore, since the device is placed close to the wall i, the air from the blower C collides with the wall i in a vertical direction and enters the device again.

Since this wind contains waste heat from the refrigeration cycle, the load increases and power consumption increases.

The present invention was developed based on the above circumstances, and its purpose is to have a relatively simple structure, but to
To provide a showcase that efficiently evaporates drain collected in a drain tray and prevents exhaust air from entering the device, thereby avoiding adverse effects on the refrigeration cycle.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 1 denotes a large open showcase main body, which is installed close to a wall 2 of the installation location.

The upper part of the main body 1 is provided with an evaporator 3 which is a cooler, a storage chamber 5 is provided with a drain port body 4a protruding from the bottom, and a storage chamber 5 whose periphery is covered with a heat insulating material 4.

In the lower part of the storage chamber 5, a drainage section 6 is provided in the center, and a pair of machine chambers 7, 7 are provided on both sides of the drainage section 6.

As shown in FIG. 3, in the drainage section 6, a tank 8 is arranged at the lowest stage, and above it there are two upper and lower stages of drainage pans 9a,
9b is placed.

The tank 8 is provided with a receiver opening 10 and a handle 11, and is detachable from the main body 1.

Each drain pan 9a, 9b is provided with an overflow pipe 12a, 12b, respectively, and the lower drain pan 9
The overflow pipe 12b of b is connected to the port 10 of the tank 8.
It is located opposite to.

Furthermore, each drain tray 9a, 9b accommodates a heating pipe 14.14 which is a heating body that is an extension of a part of a condenser 13.13 disposed in the machine room 7, which will be described later.

These heating pipes 14.14 are connected to the overflow chamber 12.
a.

It is housed in a lower part than the overflow position by 12b.

Also, between the storage chamber 5 and the upper drain tray 9a and each drain tray 9
A wind direction plate 15 is erected between a and 9b.

The wind direction plate 15 has a flat plate shape as shown in FIG.
The drainage plates 9a and 9b extend approximately halfway from the back side to the front side.

On the other hand, the machine room 7 is provided with a condenser 13, a blower 16, and a compressor 17.

The condenser 13, the compressor 17, the evaporator 3, and the heating pipe 14 communicate with each other via a refrigerant pipe (not shown) to form a refrigeration cycle.

The compressor 17 is arranged in the center of the back side passage of the machine room 7, but the condenser 13 and the blower 15 are arranged inward at an angle of approximately 45°.

Therefore, the blower 16 guides outside air from the condenser 13 side and blows it out toward the wind direction plate 15 on the oblique rear side.

In addition, an auxiliary wind direction plate 18 is installed near the compressor 17,
Together with the wind direction plate 15, it guides the wind from the blower 16.

By performing the refrigeration cycle operation, the evaporator 2 can cool the storage chamber 5 and freeze and refrigerate the stored items.

At the same time, the blower 16 is driven to guide outside air to the condenser 13 for heat exchange.

The outside air absorbs the heat of condensation, rises in temperature, and is blown out diagonally to the rear side.

Some of the wind impinges on the compressor 17 to cool it, but the rest of the wind hits the auxiliary wind direction plate 18 and the drain pans 9a, 9b.
The wind collides with the wind direction plate 15 via the wind direction plate 15.

Drain generated by defrosting the evaporator 2 is transferred from the storage chamber 5 through the outlet body 4a to the upper drain tray 9a.
Drip into.

When a large amount of drain accumulates in this upper stage, it drips into the lower drain tray 9b via the overflow pipe 12a.

Furthermore, it will collect in the tank 8 from this overflow pipe 12b.

When a predetermined amount or more of drain is collected in the tank 8, a full display is displayed, so it is necessary to take out the tank 8 from the main body 1 and drain the drain.

The heating pipe 14.14 also heats the condensate to evaporate it and reduce the amount introduced into the tank.

Furthermore, by guiding the wind from the blower 16,
Condensate evaporation efficiency increases.

In particular, since the temperature of the drain collected in the lower drain tray 9b is higher than that of the drain in the upper drain tray 9a, the blower 1
Combined with the fact that the wind of 6 is guided, extremely effective evaporation is achieved.

Since the wind direction plate 15 is provided at a location where the winds of both blowers 16 and 16 intersect, the winds of each blower do not interfere with each other.

The wind direction plate 15 guides the wind colliding with it toward the wall 2.

Since this wind impinges on the wall 2 in an oblique direction, the reflection is also in an oblique direction.

In other words, the wind is reflected diagonally to both sides of the main body 1 and does not enter the machine rooms 7, 7.

Therefore, the refrigeration cycle operation is not adversely affected.

In the above embodiment, the heating pipe 14 forming a part of the refrigeration cycle is provided as a heating body, but instead of this, for example, an electric heater may be used.

Further, although two stages of drainage dishes 9 a and 9 b are provided, the number is not limited to this.

As explained above, according to the present invention, the main body, whose back side is disposed close to the wall, has a storage chamber, a pair of machine rooms, and a drain tray between these machine rooms and a widthwise center portion on the drain tray. Equipped with a wind direction board that stands up from the back side to approximately the center,
The air blowers for cooling the condensers installed in each of the above machine rooms are slanted so that the drain pan and wind direction plate are located in the direction of the air blowing, so that the air is guided to the drain that collects in the drain pan and is efficiently used. It can be evaporated, reducing the effort required to discharge it to the outside.

Furthermore, even if the main body is placed close to the wall of the installation location, the wind from the blower, that is, the exhaust heat of the refrigeration cycle, will not flow back into the machine room again, and the load on the refrigeration cycle can be reduced.

In particular, a built-in showcase in which a storage room and a machine room are integrally formed is advantageous because the efficiency of wastewater heat treatment is greatly improved.
