  However, in the above-described conventional configuration, since a part of the wind is guided to the evaporating dish instead of the total amount of wind from the fan, in the case where a large amount of condensed water is generated at high humidity, high outdoor temperature, etc. , Evaporation promoting action in the evaporating dish is insufficient. Furthermore, since the compressor is always cooled by the wind from the fan, there is a problem that the shell temperature of the compressor is abnormally lowered especially at low outside air temperature, and the efficiency is lowered.

  In general, rotary compressors for R407C refrigerant have been used for compressors in vending machines, but conversion to HC refrigerants that are friendly to the global environment is required. However, in particular, when a reciprocating compressor for R600a refrigerant, which is highly efficient and mass-produced for refrigerators, is used, the discharge temperature is lowered due to the thermophysical properties of R600a. In addition, since the compression efficiency is high, there is little exhaust heat. For the above reasons, the discharge temperature does not rise so much and the temperature of the evaporation pipe provided in the evaporation dish becomes low, so that the evaporation performance of the evaporation dish is remarkably deteriorated.

  On the other hand, the conventional R407C refrigerant rotary compressor has a high-pressure shell structure, so that the compressor shell temperature and the discharge temperature rise, and the evaporation performance of the evaporating dish increases. However, the lubricating oil in the compressor shell, the motor material, etc. The deterioration of the organic material is easily promoted and the reliability is lowered. Therefore, in order to lower the compressor shell temperature, it is necessary to air-cool the compressor with a fan, and wind passing through the lower half of the condenser is guided to the compressor.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a vending machine that promotes evaporation of drain and prevents wind from a fan from being applied to a compressor.

In order to solve the above-described conventional problems, the vending machine of the present invention has an outdoor unit including a drive unit that cools the internal chamber of the vending machine, and the outdoor unit has a condenser at the front and a rear at the rear.

As the evaporation capacity of the compressor is increased, the air of the cooling fan is not directly applied to the compressor by the air guide to prevent overcooling of the compressor. The evaporation Guided toward, and is provided with the said air guide comprising a partition of the compressor, causes further promoted evaporation of condensed water can be prevented decrease in efficiency due to overcooling of the compressor.

  The invention according to claim 2 is the filter paper according to claim 1, wherein the filter paper that evaporates the condensed water is formed by placing the filter paper that sucks up the condensed water above the evaporating dish and applying outside air that has passed through the condenser. Since the area of the is increased, the evaporation effect can be further promoted.

The invention according to claim 3 is the invention according to claim 1 or 2, wherein HC refrigerant is used in the cooling unit for cooling the inner chamber of the vending machine, and the air guide is positioned on the opposite side of the evaporating dish. Since the HC refrigerant heavier than air is collected at the bottom of the machine room by using a vent hole in the air vent and the height of the vent hole is lower than that of the evaporating dish, a part of the wind is used for the diffusion of the HC refrigerant. By doing so, it is possible to prevent the HC refrigerant machine room from staying due to leakage or the like. In addition, the wind blown out from the air guide vent is a wind guided at a position lower than the height of the filter paper among the wind guided by the air guide, and is not a wind directly hitting the filter paper. Even if a part of the wind is diverted, the evaporation promoting action by the filter paper is not significantly reduced.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein a high humidity is expected to generate a large amount of condensed water by providing a heater at the bottom of the evaporating dish. Since the heater is energized at a high outside air temperature and the ability to promote condensation water in the evaporating dish is increased, it is possible to prevent the condensation water from overflowing.

  Here, when wind is applied to the compressor 28, the compressor 28 is cooled, the shell temperature is lowered, and a large amount of refrigerant dissolves in the lubricating oil accumulated in the shell of the compressor 28. Therefore, during the refrigeration cycle The amount of refrigerant circulating through the system is insufficient, and the capacity is reduced.

  As described above, in the present embodiment, the air guide 38 that guides the outside air that has passed through the outdoor heat exchanger 27 by the cooling fan 36 toward the evaporating dish 39 is provided, and the air guide 38 serves as a barrier for compression.

FIG. 6 is a refrigerant circuit diagram of the vending machine according to Embodiment 2 of the present invention. FIG. 7 is a plan view of the machine room of the vending machine according to the second embodiment of the present invention.

  6 and 7, the vending machine of the present invention includes a storage room including a hot / cold switching chamber 21, a cold dedicated chamber 20, and a second cold dedicated chamber 23, and includes a compressor 45, a hot / cold switching chamber. 21, an indoor heat exchanger 24 installed outside the storage room, an outdoor heat exchanger installed outside the storage room, a four-way switching valve 47 for switching the refrigerant flow path during cooling and heating, and a cooling capillary tube 48 as an expansion mechanism The heating / cold switching chamber 21 includes a cooling / heating system 46 dedicated to cooling and heating, and is installed in the compressor 52 and the cold dedicated chamber 20. The evaporator 25, the second evaporator 26 installed in the second cold dedicated chamber 23, the expansion valve 53, the second expansion valve 54, and the condenser, and the cold dedicated chamber 20 and the second cold chamber 23. A cooling system 51 for cooling the field dedicated chamber 23 only.

  Further, the apparatus includes a heat exchanger in which an outdoor heat exchanger that is a component of the cooling and heating system 46 is integrated with a condenser that is a component of the cooling system 51, and includes a cold chamber compressor 52, A heat insulating cover 56 that covers the cold switching chamber compressor 45, a cooling fan 36 that air-cools the integrated heat exchanger 55, an evaporating dish 39 that temporarily accumulates and condenses condensed water in the refrigerator, and the opposite side of the evaporating dish 39 The air guide 39 provided with a vent hole 43 at the position is disposed in the machine room.

  The operation and action of the vending machine configured as described above will be described below.

  First, when the hot / cold switching chamber 21 is cooled, the refrigerant discharged from the compressor 45 switches the flow path by the four-way switching valve 47 to the integrated heat exchanger 55 as shown by the dotted line arrow in FIG. Supplied to condense. The liquid refrigerant discharged from the integrated heat exchanger 55 is supplied to the dryer 50. The temperature of the liquid refrigerant is about 30 to 40 ° C. which is almost the same as that of the integrated heat exchanger. At this time, the liquid refrigerant stays inside the dryer 50, and moisture in the liquid refrigerant is removed.

  Then, the liquid refrigerant discharged from the dryer 50 is reduced in pressure by the cooling capillary tube 48 through the check valve and supplied to the indoor heat exchanger 24 to be evaporated, and the gas refrigerant passes through the four-way switching valve 47 again and is compressed into the compressor 45. To reflux. The evaporation temperature of the indoor heat exchanger 24 varies greatly depending on the set temperature of the storage chamber. Generally, when canned beverages or the like are cooled, the set temperature is 5 to 10 ° C, and the evaporation temperature of the indoor heat exchanger 24 is -15 to -5 ° C.

  It is desirable to install the cooling capillary tube 48 and the outlet pipe for cooling the indoor heat exchanger 24 in contact with each other. By exchanging heat, it is possible to obtain a large amount of supercooling and to improve the cooling capacity.

  When the hot / cold switching chamber 21 is heated, the refrigerant discharged from the compressor 45 is switched to the indoor heat exchanger 24 by switching the flow path by the four-way switching valve 47 as shown by the solid line arrow in FIG. Supplied to condense. The temperature of the liquid refrigerant varies greatly depending on the set temperature of the storage chamber. Generally, when a can beverage or the like is heated, the set temperature is 50 to 60 ° C, and the condensation temperature of the indoor heat exchanger 24 is 60 to 80 ° C.

  In addition, it is desirable to cover the heating refrigerant pipe from the compressor 45 to the indoor heat exchanger 24 with a heat insulating material, thereby improving the heating capacity and the heating efficiency by preventing heat radiation from the heating refrigerant pipe. Can be made.

  The liquid refrigerant from the indoor heat exchanger 24 is immediately depressurized by the heating capillary tube 49 and then supplied to the integrated heat exchanger 55 via the check valve to evaporate, so that the gas refrigerant is again four-way. It returns to the compressor 45 through the switching valve 47.

  Next, when the cold exclusive chamber 20 and the second cold exclusive chamber 23 are cooled, the refrigerant discharged from the compressor 52 is supplied to the integrated heat exchanger 55 for condensation as shown by the dotted arrows in FIG. Liquefaction. The liquid refrigerant from the integrated heat exchanger 55 is split into two hands and decompressed by the expansion valve 53 and the second expansion valve 54, respectively, and then supplied to the evaporator 25 and the second evaporator 26 to be evaporated. The cold dedicated chamber 20 and the second cold dedicated chamber 23 are cooled. Thereafter, the gas refrigerant joins again and returns to the compressor 52.

  The integrated heat exchanger 55 is constituted by a two-pass fin tube heat exchanger, and one of the passes is connected to the cooling and heating system 46, and acts as an evaporator during heating and as a condenser during cooling. The other path is connected to the cooling system 51 and acts as a condenser.

  Here, in the integrated heat exchanger 55, when the cooling system 51 is operated, the path connected to the cooling system 51 acts as a condenser, and the fin temperature around the path becomes high. Therefore, when the cooling and heating system 46 and the cooling system 51 are operated simultaneously, cascade heat exchange can be performed via the fins, and the air warmed by the condenser can be sucked into the evaporator. The cooling and heating system 46 can be operated at a high evaporation temperature of -10 ° C. Thereby, the compression ratio can be reduced even under severe heating conditions of a condensation temperature of 60 to 80 ° C., and the efficiency of the compressor 45 can be improved. Further, in the cooling system 51, the efficiency of the compressor 52 can be improved by lowering the condensation temperature.

  Moreover, since the compressor 45 is covered with the heat insulation cover 56 and the wind from the cooling fan 36 is interrupted | blocked, the shell temperature of the compressor 45 can be maintained high and heating efficiency improves.

  Further, by providing the air holes 38 of the air guide 38 on the opposite side of the evaporating dish 39 and at a position lower than the evaporating dish 39, it is possible to avoid direct hitting of the cold chamber compressor 52. At the same time, the HC refrigerant can be prevented from staying in the machine room due to leakage or the like.

  As described above, in the present embodiment, the integrated heat in which the cold chamber compressor 52, the heat insulating cover 56 covering the hot / cold switching chamber compressor 45, the outdoor heat exchanger and the condenser are integrated. A cooling fan 36 for air-cooling the exchanger 55 and an evaporating dish 39 for temporarily condensing the condensed water in the warehouse and evaporating the air are provided in the machine room, and an air vent 43 is provided at a position opposite to the evaporating dish 39. A guide 38 is provided to supply wind around the hot / cold switching chamber compressor 45, thereby avoiding direct hitting of the cold chamber compressor 52, and the hot / cold switching chamber compressor 45. The HC refrigerant is prevented from staying in the vicinity, and the waste heat of the condenser integrated with the outdoor heat exchanger is used for evaporation of the condensed water in the evaporating dish 39, so that the evaporation performance is improved.

  As described above, the vending machine according to the present invention is provided with an air guide that guides the total air volume from the fan to the evaporating dish and does not apply wind to the compressor, so that the hot beverage and the cold beverage are switched and stored. It can also be applied to uses such as showcases that require energy saving during heating and cooling.
