Abstract
The utility model discloses a direct defrosting type freezer for commercial showing, comprising a refrigerating compressor unit installed in the lower part and a freezer body for placing articles in the upper part. The position near an evaporator on the refrigerating compressor unit is installed with a heater plate capable of covering the entire evaporator area. The defrosting of the evaporator of the freezer is directly heated by the heater plate capable of covering the entire evaporator area, and as a result, the heat radiation area is big and uniform, and the defrosting efficiency is high. What's more, the direct heating defrosting by the heater plate is carried out in the condition of turning off the evaporating blower, so no circulation of the air curtain is generated when heating, and the heat cannot be carried to the freezer body; the shot defrosting time cannot cause the commercial articles in the freezer body to deteriorate. Compared with the exiting electric heating tube defrosting, the defrosting time of the adopted heater plate defrosting on the same showing freezer can be shortened 1/3; the temperature in the freezer after defrosting by the electric heating tube is 2.6 times of the temperature after defrosting by the heater plate. Therefore, the multi-aspect effects brought by defrosting by the adoption of the electric heating plate are obvious.
Description
Technical field
The utility model belongs to display refrigerator, specifically a kind of directly commercial show freezer of defrosting device that self has.
Background technology
Have now at the refrigeration of market use or freezing commercial show cabinet, defrost mode to its evaporator surface, be that a plurality of electrothermal tubes that utilize the refrigerator bottom to install produce heat, again heat is dried by evaporation fan, promptly come defrost as the evaporator surface that the medium of heat are diffused into outside frosting with wind, the shortcoming of this defrost mode is: the heat that electrothermal tube produces is in the part, need make medium with wind through heat exchange, hot blast is blown to evaporator surface carry out indirect defrost, its heat exchange can not be very even, area of dissipation is also little, and the defrost time is long, and efficient is low; In addition, with wind is that medium come defrost, when wind is delivered to evaporator surface with heat, the circulation of refrigeration air curtain also with the heat of part defrost in cabinet is taken in the air channel to, make temperature rising in the cabinet, cause the loss of energy and the waste of the energy, make the article under refrigerating state in the cabinet rotten because of defrost easily.
The utility model content
Inhomogeneous for solving display refrigerator with the heat exchange of electrothermal tube heating, blower fan blowing defrost, area of dissipation is little, problems such as defrost efficient is low, the technical solution of the utility model is: refrigerator comprises cabinet and refrigeration compressor set, the position of nearly evaporimeter is equipped with the heating plate that can cover whole evaporator area in cabinet.
Pass in the cabinet of top for the heat that does not produce because of heating plate when the defrost rises, between the top of heating plate and cabinet, be provided with heat-insulation layer, and form a relative enclosure space.
Because the defrost of refrigerator is not an indirect type of propagating heat with wind as hot media, therefore not with cabinet in the process of displaying merchandise heat exchange, but directly heating defrost by the heating plate that can cover whole evaporator area, its area of dissipation is big and even, defrost efficient height; Moreover, directly heat defrost with heating plate, be to carry out under the situation that evaporation fan shuts down when defrost, there is not the circulation of air curtain during heating, the heat of defrost can not be brought in the cabinet yet, temperature in the cabinet only in the inner defrost of evaporimeter, slow rising is arranged when refrigeration compressor set quits work, and the defrost time is short, can not make the commodity in the cabinet rotten.If adopt heating plate defrost and electrothermal tube defrost comparison on same showcase, its defrost time can shorten 1/3, is 2.6 times of temperature after the heating plate defrost with the in-cabinet temperature after the electrothermal tube defrost.In view of this, the many-sided benefit that adopts the electric hot plate defrost to be brought is very significant.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a cross-sectional schematic of the present utility model.
The specific embodiment
Among Fig. 1, commercial show freezer is included in the cabinet or outer refrigeration compressor set of installing 5 of cabinet and the cabinet 1 of placing displaying articles, on position plane near evaporimeter 4, the heating plate 3 that whole evaporimeter 4 can be covered is installed, and the heat that heating plate 3 energising backs produce melts the frost on the evaporimeter 4; Heating plate 3 can be installed in the top of evaporimeter 4, perhaps is installed in the bottom of evaporimeter 4, and is faster in order to make defrost, also can installing simultaneously up and down at evaporimeter 4.Described display refrigerator can be a single face, also can be symmetrical as shown in the figure cabinet form.
Do not pass to the displaying merchandise on cabinet 1 top for the heat that does not produce because of heating plate 3 when the defrost rises, below the bottom surface of heating plate 3 top cabinets 1, can be provided with heat-insulation layer 2.If heating plate 3 is installed in the top of evaporimeter 4, then heat-insulation layer 2 can directly be attached to the upper face of heating plate 3; If heating plate 3 is installed in the bottom of evaporimeter 4, then heat-insulation layer 2 can be installed in below the cabinet 1 and between the evaporimeter 4, and forms a space that relative closure is heat insulation.
During defrost, stop the work of refrigeration compressor set 5, close evaporation fan 7, be heated to temperature, the time of setting for heating plate 3 energisings, water after the defrost flows out from the drainpipe 6 of bottom, restarts refrigeration compressor set 5, and display refrigerator can restart work.
Claims (4)
1, a kind of direct defrosting type commercial show freezer, comprise the refrigeration compressor set of display refrigerator bottom installation and the cabinet that article are placed on top, it is characterized in that: the nearly evaporimeter position on refrigeration compressor set is equipped with the heating plate that can cover whole evaporator area.
2, direct defrosting type commercial show freezer as claimed in claim 1, it is characterized in that: heating plate can be installed in the top of evaporimeter.
3, direct defrosting type commercial show freezer as claimed in claim 1, it is characterized in that: heating plate can be installed in the bottom of evaporimeter.
4, as claim 1,2 or 3 described direct defrosting type commercial show freezers, it is characterized in that: between the top of heating plate and cabinet, be provided with heat-insulation layer.
