Description

Freezer supply fan to prevent freezing and deformation of water collecting tray

The present invention belongs to the technical field of freezers, in particular to an anti-icing and deformation water collecting tray for a blower of a freezer.

The structure of a freezer is generally divided into a box, a refrigeration system, and an electrical system.

The basic function of the freezer is to refrigerate, so as to maintain a proper low temperature in the box. The refrigeration system generally consists of four basic components: compressor, condenser, capillary or thermal expansion valve, and evaporator. Refrigerant is a liquid that can boil at low temperature at low pressure. It absorbs heat when it boils. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant, resulting in liquefaction conditions. When passing through the condenser, it condenses and liquefies and releases heat. , and then reduce the pressure and temperature when passing through the capillary, and then boil and vaporize to absorb heat when passing through the evaporator. In addition, the use of refrigeration diodes is now developed. There is no complicated mechanical device, but the efficiency is poor, and it is used in small refrigerators.

Generally, there is a water collecting tray at the bottom of the blower of a large freezer, through which the water generated by the blower of the freezer due to the defrosting function is collected and drained. Frozen, when the drain hole of the water collecting tray is blocked by ice, it will cause problems of poor drainage and deformation of the water tray due to freezing.

In view of this, it is indeed necessary to provide a technical means to solve the problem that the drainage hole of the water collecting tray is blocked due to freezing.

The purpose of this new model is to solve the problems of blockage and deformation of the water tray caused by the freezing of the drainage hole of the water collecting tray.

In order to achieve the aforementioned purpose, the present invention is an anti-icing deformation water collecting tray for a freezer blower, comprising:

a bottom water pan with a water collecting space and a side wall surrounding and defining the water collecting space;

A top-level water tray has a water-retaining plate, the water-retaining plate has a bottom surface and a drain hole is opened, the top-level water tray is further provided with an electric heating belt disposed on the bottom surface, and the top-level water tray is used for containing the water on the side wall. The drain hole communicates with the water collection space, the bottom surface faces the water collection space, and the electric heating belt is located in the water collection space.

In a preferred embodiment, the bottom water pan has a bottom wall connected to the side wall, a drain port is defined on the bottom wall, and the drain port is connected to an external drain pipe.

In a preferred embodiment, the bottom wall has a plurality of inclined surfaces facing the water outlet.

In a preferred embodiment, the water-receiving plate has a top surface opposite to the bottom surface, and one end of the electric heating tape passes through the bottom surface and protrudes from the top surface.

In a preferred embodiment, the heating tape is fixed to the bottom surface through a plurality of stainless steel coils.

Since the electric heating belt is provided on the top water tray, the ice adhering to the water holding plate can be melted through the electric heating belt, thereby preventing the ice from blocking the drainage hole. More preferably, since the electric heating belt is disposed in the water collecting space, the heat energy generated by the electric heating belt is accumulated in the water collecting space, thereby also melting ice condensed in the water collecting space.

Please refer to Figures 1 and 2. The present invention is an anti-icing and deformation water collecting tray for a freezer blower, which mainly includes a bottom water tray 10 and a top water tray 20, wherein:

The bottom water pan 10 has a water collecting space 11 and a side wall 12 surrounding and defining the water collecting space 11 ; in this embodiment, the bottom water pan 10 has a bottom wall 13 connected to the side wall 12 , the bottom wall A drain port 14 is provided on the 13 , and the drain port 14 is connected to an external drain pipe for discharging the water accumulated in the water collecting space 11 .

The top water tray 20 has a water holding plate 21, the water holding plate 21 has a bottom surface 211 and a drain hole 22, and the top water tray 20 further has an electric heating belt 23 disposed on the bottom surface 211, the top water tray 20 is provided with The drain hole 22 is placed on the side wall 12 and communicates with the water collection space 11 , and the bottom surface 211 faces the water collection space 11 , and the electric heating belt 23 is located in the water collection space 11 ; The heating belt 23 is an explosion-proof electric heating belt, the input power is 220V, and the output specification is 90W/m. However, the heating belt 23 is not limited to the use of the explosion-proof electric heating wire mentioned above. Of course, it can also be a semiconductor heating wire, rubber heating wire, defrosting When electrifying the heating belt, etc., different heating belts 23 are selected according to the needs of the user, which can have different effects such as power saving, rapid heating, less damage, and easy replacement.

In the present embodiment, the bottom wall 13 has a plurality of inclined surfaces 131 facing the water outlet 14 . By being inclined toward the water outlet 14 , the water falling into the water collecting space 11 can follow the inclined surfaces. 131 is guided to the drain port 14 for discharge.

Secondly, the water-receiving plate 21 has a top surface 212 opposite to the bottom surface 211 , the top surface 212 is used for receiving water. One end of the heating tape 23 protruding from the top surface 212 can be wrapped with insulating tape, of course, not limited to the foregoing method, and one end of the heating tape 23 can also be sealed with an insulating rubber sleeve.

Furthermore, the gap between the top water pan 20 and the bottom water pan 10 can be additionally filled with silicone to prevent water leakage. Of course, other caulking methods can be used between the top water pan 20 and the bottom water pan 10 to achieve the same anti-leakage effect.

Finally, the heating tape 23 is fixed on the bottom surface 211 through a plurality of stainless steel coils, so that the heating tape 23 is adhered to the bottom surface 211, so that the heat energy generated by the heating tape 23 can be completely transferred to the water holding plate 21, so that the The ice condensed on the water holding plate 21 is melted faster.

The above is the structural configuration and the connection relationship of the new model in a preferred embodiment. The use method of the new model and the effects it can produce are as follows:

Please refer to FIG. 1 and FIG. 2 , when the water droplets of the freezer are frozen on the water holding plate 21 due to the temperature in the freezer, frost will adhere to the top surface 212 of the water holding plate 21 , and the electric heating belt 23 will heat up. Afterwards, its heat energy will be transferred to the water holding plate 21 , thereby melting the ice attached to the water holding plate 21 , and the melted water can flow into the water collecting space 11 through the drainage hole 22 .

The melted water flows into the water collecting space 11 through the drain hole 22 , falls on the inclined surface 131 , flows into the drain port 14 with the guidance of the inclined surface 131 , and finally drains to the outside.
