DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the evaporating dish according to the present invention will be described in detail below with reference to the accompanying drawings.
[0007]
1 and 2 show an embodiment of an evaporating dish according to the present invention, and FIG. 3 is a schematic configuration diagram showing a machine room of a storage in which the evaporating dish is arranged. As shown in the figure, in the machine room 10 of the storage, a compressor 12 is disposed at the bottom, and a resin evaporating dish 14 and a condenser 16 are sequentially arranged in a vertical shape above the compressor 12. Then, the refrigerant is circulated and supplied from a refrigeration apparatus 18 including a compressor 12 and a condenser 16 to a cooler (not shown). Moreover, the defrost water etc. which generate | occur | produced with the cooler are collect | recovered and stored by the said evaporating dish 14 via the path | route which is not shown in figure. The bottom surface portion 14a of the evaporating dish 14 is positioned so as to be close to the upper surface of the compressor 12, and is configured to heat the evaporating dish 14 and evaporate defrost water or the like by the heat generating action of the compressor 12. .
[0008]
A discharge pipe 20 led out from the compressor 12 and connected to the condenser 16 is disposed and fixed on the bottom surface portion 14a of the evaporating dish 14, and is configured to evaporate the defrost water stored by the heat generating action of the discharge pipe 20. Has been. That is, as shown in FIG. 1, a plurality of grooves 22 that open downward are formed in parallel at predetermined intervals on the bottom surface portion 14a of the evaporating dish 14, and the grooves 22 are formed in a meandering manner. The parallel portion 20c of the discharge pipe 20 is inserted and positioned. The inlet side 20a or the outlet side 20b is supported and fixed to the extending end of the groove 22 corresponding to the start end (inlet side 20a) and the end (outlet side 20b) of the discharge pipe 20 attached to the evaporating dish 14. Possible rib-like projections 24 are provided, and the inlet side 20 a or the outlet side 20 b corresponding to each rib-like projection 24 is supported and fixed by a binding band 26. The depth of the groove 22 is set to be larger than the diameter of the discharge pipe 20, and the discharge pipe 20 fitted in the groove 22 is configured not to protrude from the lower open portion of the groove 22.
[0009]
As shown in FIG. 2, a metal evaporating plate 28 is fixed to the bottom surface portion 14 a of the evaporating dish 14 via a plurality of screws 30 so as to face the outside of the discharge pipe 20. Thus, the discharge pipe 20 is prevented from dropping off from the evaporating dish 14 completely. The evaporation plate 28 is made of a material having good heat conduction such as copper or aluminum, and functions to efficiently transfer heat from the discharge pipe 20 and the compressor 12 to the evaporation dish 14. In addition, the evaporation plate 28 is set to a size that can cover substantially the entire lower open portion of the plurality of grooves 22 into which the parallel portions 20 c of the discharge pipe 20 are inserted, and evaporates heat from the discharge pipe 20 and the compressor 12. It is comprised so that it can convey over the whole dish 14. FIG.
[0010]
[Effect of the embodiment]
Next, the operation of the evaporating dish according to the embodiment will be described below. When fixing the discharge pipe 20 to the evaporating dish 14, first, each parallel portion 20c of the discharge pipe 20 is inserted into the groove 22, and the evaporating plate 28 is screwed to the bottom surface part 14a of the evaporating dish 14. Fix it. This reliably prevents the discharge pipe 20 from dropping off. Further, even when the evaporating dish 14 has sledges or dings, the elongating plates 28 can be fixed by fixing the evaporating plate 28 to the evaporating dish 14.
[0011]
Next, the inlet side 20 a and the outlet side 20 b of the discharge pipe 20 are supported and fixed to the corresponding rib-like protrusions 24 via the binding bands 26, respectively. Thereby, the inlet side 20a and the outlet side 20b of the discharge pipe 20 are firmly fixed to the evaporating dish 14, and the resonance caused by the vibration caused by the operation of the compressor 12 and the operation of the refrigeration system is prevented, and the generation of unpleasant noise and The discharge pipe 20 can be prevented from falling off.
[0012]
Further, the defrost water and the like collected and stored in the evaporating dish 14 provided with the discharge pipe 20 on the bottom surface portion 14 a is evaporated by heat of the discharge pipe 20 and heat from the compressor 12. In this case, since the lower open part of the groove 22 into which the discharge pipe 20 is inserted is closed by the evaporation plate 28, the heat of the discharge pipe 20 can be transmitted to the entire evaporating dish 14 without being released. . Furthermore, heat from the compressor 12 can be transmitted to the entire evaporating dish 14 by the evaporating plate 28, and efficient evaporation of defrosted water or the like is achieved.
[0013]
Here, the resin-made evaporating dish is inferior in thermal conductivity to the metal evaporating dish, but the discharge pipe 20 is inserted into the groove 22 formed in the bottom surface portion 14a of the evaporating dish 14 as in the embodiment. The metal evaporating plate 28 is disposed on the bottom surface portion 14a so as to face the outside of the discharge pipe 20 while being inserted, so that defrosted water or the like has substantially the same efficiency as a metal evaporating dish. The evaporation of can now be achieved. Moreover, since the evaporating dish 14 is made of resin, rust does not occur even after long-term use, and the cost for mass production can be reduced. Although it is conceivable to adopt the configuration of the embodiment with the evaporating dish 14 made of metal, in this case, in addition to the problems of rust and cost as described above, the fitting with the metal discharge pipe 20 is possible. Cause problems such as difficulty in processing, and the processing cost is increased due to processing into a complicated shape. On the other hand, when the evaporating dish 14 is made of resin, the fitting with the discharge pipe 20 is easy, and it is easy to form into a complicated shape, and the increase in cost can be suppressed.
[0014]
The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and many design changes can be made without departing from the spirit of the present invention.
[0015]
【The invention's effect】
As described above, in the evaporating dish according to the present invention, the discharge pipe is fitted into the groove formed in the bottom part of the evaporating dish, and the evaporating plate is disposed on the bottom part, so that the resin evaporating dish is provided. The heat of the discharge pipe can be efficiently transmitted to the whole, and the defrost water and the like collected and stored in the evaporating dish can be efficiently evaporated. Further, since the evaporating dish is made of resin, it is possible to solve the problem that rust is generated and the manufacturing cost is increased as compared with the metal dish. In addition, since the evaporating dish is positioned so that the bottom surface portion is close to the upper surface of the compressor, the evaporating plate can also transmit heat from the compressor to the entire evaporating dish, and efficient evaporation of defrost water and the like. Is achieved.
