Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain processing device for evaporating and discharging drain generated in a product storage room or the like in a vending machine for selling products such as cold beverages. 2. Description of the Related Art A vending machine for cooling and selling canned beverages and the like is provided with a refrigerating device in the machine and a drain processing device for processing drain generated during cooling of products. Generally, those shown in FIGS. 4 and 5 are known. In the drawing, reference numeral 1 denotes a condensing unit which constitutes a refrigerating device together with a cooling unit (not shown) installed in a product storage room. A machine room is defined and installed here. The condenser unit 1 is provided on a base 11 fixed to the machine room bottom plate, facing the vent hole.
2. Next, a condenser cooling fan 13, a compressor 14, and an exhaust fan 15 are arranged in a row in the rearward direction. Reference numeral 3 denotes a drain treatment device installed near the condensing unit 1, which includes a mounting table 31 fixed to the bottom plate of the machine room, and a drain plate 32 mounted on the mounting table 31. A drain pipe 3 for guiding the drain generated in the product storage room to the drain plate 32
3 are connected and open into the dish. An evaporating pipe 34 is formed to draw out a part of a refrigerant pipe connecting the condenser 12 and the compressor 14 and formed in a coil shape, and an evaporating mat 35 is provided so as to be entangled with the evaporating pipe 34. The vending machine cools the product in the product storage room by a cooler of a cooling unit, and the refrigerant gasified by the cooling is sent to the condensing unit 1 and is compressed by the compressor 14 to be hot and high-pressure hot gas. Next condenser 12
Flowing inside. Then, it is sucked by the fan 13 and liquefied by heat exchange with the outside air for washing and cooling the condenser 12, and is sent to the cooler again. The outside air is guided to the duct 16 and flows to the compressor 14 to cool the compressor 14 and to cool the exhaust fan 15.
Is discharged by. On the other hand, in the drain treatment device, the drain in the product storage room is collected on a drain plate 34 via a drain pipe 33. The drain is heated by the hot gas flowing through the evaporating pipe 34, and is evaporated from the drain plate and from the evaporating mat 35 having a large evaporating surface area by absorbing the drain into the evaporating mat 35. [0004] In this type of vending machine, the amount of drain accumulated in a drain plate due to the partitioning of the product storage compartment into small compartments to increase the number of compartments or the decrease in evaporation temperature due to a change in refrigerant material. And there is a demand for increasing the processing capacity. However, it is difficult to increase the size of the drain plate 32 and the evaporating pipe 34 because the machine room must be enlarged. SUMMARY OF THE INVENTION It is an object of the present invention to provide a drain processing apparatus for a vending machine capable of increasing the drain throughput while keeping the capacity of a drain plate and an evaporation pipe unchanged. [0006] SUMMARY OF THE INVENTION The present invention in order to achieve the above object, a condenser arranged sequentially one row in a machine room which is defined and formed in the lower portion of the main body case, the cooling fan and the front
A condenser unit comprising a compressor approximately half the height of the condenser, and a drain plate juxtaposed to the condenser unit, and a part of the refrigerant pipe of the condenser is drawn into the drain plate to evaporate. A pipe and an evaporation mat are provided,
The drain collected in the drain dish is passed through the evaporation pipe,
In a drain processing device of a vending machine that evaporates by an evaporating mat, a part of the outside air in which a condenser is rinsed and cooled by the cooling fan is provided between the cooling fan and the compressor of the condensing unit. an air guide for directed guiding provided, the air guide of the outside air and the condenser was washed flow cooling, is passed through a fresh air in the lower region, characterized by guiding the outside air of the upper region towards the drain pan. [0007] By blowing a part of the outside air that has cooled the condenser to the drain pan and above, the steam that has been heated and evaporated from the drain pan is blown off from above the drain pan and around the evaporating mat to promote evaporation. . Accordingly, it is possible to increase the drain throughput while keeping the drain pan and the evaporating pipe at the conventional size. FIG. 1 to FIG. 3 show an embodiment of the present invention, and portions common or identical to those in FIGS. 4 and 5 are denoted by the same reference numerals. 1 to 3, reference numeral 37 denotes an air guide provided on the discharge side of the fan 13. The air guide 37 has two guide portions 37a for guiding the outside air sent out through the upper portion of the condenser 12 toward the drain treatment device 3, and is provided on the upper end surface of the condenser 12 via a mounting portion 37b. Fixed. In the above-described configuration, the outside air taken in from the ventilation hole on the front of the machine room by the fan 13 cools the condenser 12, and the outside air sent out through the lower half thereof rinses and cools the compressor 14 to exhaust the air. It is discharged by the fan 15. The outside air sent out through the upper half of the condenser 12 is guided toward the drain treatment device 3 by the air guide 37, and the evaporating mat 35 and the evaporating pipe 34 are extended over the entire length by two guide portions 37a. The air is exhausted by the blow-by exhaust fan 15. The drain collected in the drain tray 32 is heated by the evaporation pipe 34 and evaporates from the drain tray 32 and the evaporation mat 35, and the vapor is guided to the air guide 37 without stagnation above the drain tray 32 and around the evaporation mat 35. It is blown off by the outside air and discharged. Therefore, the evaporation of the drain from the drain plate 32 and the evaporation mat 35 is continuously and vigorously performed, and a much larger amount of drain is evaporated than in the conventional case. The height of the compressor 14 is substantially half of that of the condenser 12 and is cooled by the outside air sent through the lower half of the condenser 12 as before. According to the present invention, the condensers are sequentially arranged in a line in the machine room defined at the lower part of the main body case.
A condensing unit consisting of substantially half the height of the pressure <br/> compressor with respect to the cooling fan and the condenser, and a drain pan which is juxtaposed to the condensing unit, the refrigerant pipe of the condenser one An evaporating mat provided with an evaporating pipe, wherein the condensing part is drawn into a drain pan, and a drain processing device of a vending machine for evaporating the drain collected in the drain pan by the evaporating pipe and the evaporating mat. An air guide is provided between the cooling fan of the unit and the compressor to guide a part of the outside air, which has been washed and cooled by the cooling fan to the condenser, toward the drain pan, and the air guide serves as a condenser. of the outside air flushing cooled, passed through a fresh air in the lower region, by which the outside air of the upper region configured to guide toward the drain pan, evaporation is promoted air volume impinging on the evaporation mat is increased And driving away the vapor of the upper drain pan is drained by evaporation pipe evaporation are carried out to actively continue with. Thus, it is possible to process a remarkably large amount of drain without increasing the capacity of the drain plate and the evaporating pipe as compared with the conventional case.Furthermore, since the arrangement configuration of the condensing unit is not significantly changed, the existing structure is not changed. It has the advantage that it can be added to the condensing unit and that the cooling of the compressor is not impaired.
