The drain water D coming from the showcase is caught and held by the fan casing 18 for the blower fan disposed opposite to the condenser 8, and the fan casing 18 being formed with porous material 21 which allows the drain water to be evaporated from its surface.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a drain treatment device for a showcase, and in particular to a fan casing of a blower fan that blows drain water flowing out from a warehouse to a condenser. The present invention relates to a showcase drain processing device that can perform forced evaporation using water.

(Prior art) In general, in a showcase, an evaporator for exchanging heat with the air inside the store is housed at the bottom of a storage chamber where products are stored, and a pressure amitter, a condenser, etc. are housed at the bottom of the showcase body. Room III is constructed.

(Problems to be Solved by the Invention) By the way, drain water is generated in the refrigerator due to the operation of the showcase. This drain water is led into the machine room below the main body through a drain pipe and drips down.

Therefore, in order to treat this drain water, a drain treatment device for evaporating the drain water has conventionally been provided. Conventional drain processing equipment consists of a drain tray installed at the bottom of the machine room, and this drain tray stores drain water dripping from the evaporator, and uses the ventilation heat of the 1i1 condenser ventilation fan to collect the drain water. It was evaporating. For this reason,
Conventionally, there was a problem in that a space and a mounting structure were required to install the drain dish.

The present invention has been devised to effectively solve the above problems.

The present invention makes it possible to forcibly evaporate drain water by using the fan casing of the blower fan that blows air into the condenser, which has a simple structure, saves space, and increases the condensing capacity of the condenser. The purpose of the present invention is to provide a drain processing device for a showcase that can be used for drain treatment.

[Configuration of the Invention (Means for Solving the Problems) The present invention provides a blower fan in a machine room of a showcase opposite to a condenser that constitutes a refrigeration cycle, and
In the showcase equipped with a fan casing that covers the area around the blower fan and guides air to the condenser, the fan casing is formed of a porous material, and the drain water generated inside the refrigerator is dripped onto the upper part of the fan casing. It is configured as follows.

(Function) Drain water that flows from the inside of the refrigerator to the machine room side flows down to the fan casing of the condenser blower fan, which is made of a porous member located below the drain pipe, is captured by the fan casing, and remains inside the porous member. I will do it. This captured drain water is vaporized from the surface of the porous member by the blower fan, and the vaporized and cooled air passing through the surface of the porous member is sent to the condenser and can cool the condenser. , the drain water is evaporated.

In addition, the drain water retained in the porous member is evaporated by exchanging heat with the air through ventilation by the ventilation fan, lowering the surface air temperature and being blown to the condenser, which improves the condensing capacity of the condenser. Become.

(Example) Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 shows the entire showcase, and the showcase main body 1 is formed with a storage 3 mainly partitioned by glass plate materials 2, and the lower part of the main body 1 below the storage 3 has a storage compartment 3. As shown in FIG. 2, a machine room 4 is partitioned from a storage room side by a heat insulating partition member 5.

A compressor 7 that constitutes refrigeration cycle components, a condenser 8 that exchanges heat with outside air, and a condenser fan 9 are housed on the bottom plate 6 of the machine room 4.

Further, in the upper part 10 of the heat insulating partition member 5, an evaporator 11 constituting a refrigeration cycle component is placed, and an evaporator fan 13 for blowing indoor air 12 onto the evaporator 11 is housed to form a cooling chamber 14. do. A storage 3 is formed above the cooling chamber 14, and a fan 13 in the cooling chamber 14 guides the air 12 inside the refrigerator to an evaporator 11 for cooling.

Further, a drain discharge hole 16 penetrating toward the machine room side is formed in the lower part 15 of the heat insulating partition member 5, and this discharge hole 16
A drain pipe 17 is inserted into the drain pipe 17, and a drain port at the tip of the drain pipe 17 faces above a fan casing 18 provided around a blower fan 9 facing the condenser 8. .

Therefore, the drain water flowing out from the inside of the refrigerator drips from the drain pipe 17 onto the upper surface of the fan casing 18 directly below the drain pipe 17.

In particular, in the present invention, the fan casing 18 of the blower fan provided opposite to the 1i condenser 8 is made of a porous material that captures and retains drain water flowing out from the inside of the refrigerator and evaporates the drain water from the surface. It is formed by the member 21.

The porous member 8 is made of a heat-reactive phenolic high-performance thermosetting resin or the like having a particle size of 5 to 800 μl at 150°C to 160°C.
It is sintered and formed with a large number of pores (porosity: 36%).
It is a hydrophilic sintered body having a certain degree of hydrophilicity.

The shape of this highly functional thermosetting resin sintered body is molded into a flat plate, which is then cut and bent into a desired shape.

Specifically, the mold is kept at 90°C to 100°C, granular resin is put into it, and the molding pressure is set to 0 to 5 g/cn + 2 mold temperature of 160°C and a molded product thickness of 20 to 45°C.
75 minutes, and in the case of a molded product with a thickness of 511111, hold for 30 to 60 minutes to form a plate 22 as shown in FIG. Paste it like this.

In another embodiment, a plate material 22 is formed in the same manner, and the formed plate material 22 is cut as shown in FIG. That is, a circular hole 23 that becomes the fan casing of the condenser blower fan 9 is formed approximately in the center of the molded plate material 22, and the sides 24, 25, 26 of the long axis expanded on three sides and a pair of overlapping portions 27 are formed. Form.

These side portions 24, 25, and 26 are bent at approximately right angles so as to face each other at bent portions 29, 30, leaving a substantially square portion 28 having a circular hole 23. As a result, as shown in FIG. 6, when raised from the floor surface, a box-shaped porous member 21 having an upper side 31 and a pair of side sides 32 is formed.

As shown in FIG. 7, the porous member 21 formed by cutting and bending in this manner has its upper side 31 located directly below the drain pipe 17, so that the air from the blower fan 9 is guided to the condenser 8. Thus, the fan casing 8 is formed.

Therefore, the entire porous member 21 in this case serves as an absorber that absorbs the drain D, and also forms a casing that guides the air from the condenser fan 9 to the condenser 18.

Therefore, the drain water discharged from the drain pipe 17 is first dripped onto the upper side 31, and sequentially permeates from the upper side 31 to the square portion 28 and side portion 32 below it, and during operation, the porous member The drain water sucked up by 21 exchanges heat with the air passing through the surface by the ventilation of the blower fan, and is evaporated into the air.

As described above, the present invention allows the porous member 21 to form the condenser fan casing 18 while capturing and retaining the drain water flowing out from the inside of the refrigerator, and forcibly evaporating the absorbed drain water using the blower fan. As a drain evaporation treatment device, the structure is simple and inexpensive, and no installation space is required for a drain pan.

[Effects of the Invention] In summary, the present invention exhibits the following excellent effects.

(11) The porous member forms the gauging of the condenser blower fan and evaporates the drain water flowing out from the refrigerator using the wind of the blower fan, so the structure is simple and the installation space of the device is not required.

C2 Ri The condensing capacity of the condenser can be increased by using the heat of vaporization of drain water, and the condenser can be made smaller. I can do two things.
