In addition, to cooler 26 bottoms Defrost heater 32 is installed, is caused to form the draining generation steam that drips on the heater surfaces of high temperatureization, thereby make this water vapour from 27 ejections of cold wind ejiction opening, the condensation in passage 24 of this water vapour causes problems such as secondary frosting.Therefore, need make 32 contacts of draining discord heater as far as possible being mounted to, and aspect such as time that dewaters is set takes time and energy.
In addition, in the occasion that 1 pressure fan 25 is set, because air stream vertically enters cooler 26 along cooler, at two ends roughly, air themperature rises, thereby cooler 26 temperature rising non-uniform phenomenons occur.
The present invention is just in order to solve the problem that above-mentioned existing Defrost heater configuration structure exists, its purpose is to provide and Defrost heater capacity, number can be limited to bottom line, cost is reduced and can reliably defrost, in addition, can also be to the part beyond the cooler, for example defrost around the passage, and also can heat the low-temp goods showing cabinet Defrost heater configuration structure of the draining that defrosts smoothly the Drainage Division.
For achieving the above object, the present invention possesses pressure fan and the cooler that disposes successively from weather side in the cold wind circulation canal, the cold wind of the device cooling that is cooled is sprayed to casing the place ahead from the cold wind ejiction opening that forms on box back surface top, cover casing top opened portion with the cold wind air curtain, make to keep low temperature in the case, it is characterized in that, the 1st Defrost heater nearby is set at above-mentioned cold wind circulation canal intercooler weather side cooler, in addition, in pressure fan windward one side the 2nd Defrost heater is set.In addition, preferably make the caloric value of above-mentioned the 1st Defrost heater be equal to or greater than the caloric value of the 2nd Defrost heater.
Because the 2nd Defrost heater defrosts to it with heated air indirect cooler, thereby the efficiency of heating surface is not high, yet even 1 pressure fan occasion is being set, can makes along the cooler longitudinal temperature and evenly rise, its result can reliably defrost.
In addition, the air that can use heating for example can be to defrosting around the passage and also can heating the draining that defrosts smoothly to the Drainage Division to the part beyond the cooler.
In addition,, thereby the capacity and the radical of the 1st Defrost heater can be limited to bottom line, can very effectively prevent water vapour, avoid producing the trouble of secondary frosting because the 2nd Defrost heater is brought into play above-mentioned effect.
Simple declaration to accompanying drawing:
Fig. 1 is expression horizontal type low-temp goods showing cabinet Defrost heater configuration structure one embodiment sectional side view of the present invention,
Fig. 2 represents the sectional side view of existing horizontal type low-temp goods showing cabinet Defrost heater configuration structure one example.
