Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing machines, in particular to an air defrosting device for an evaporator of a quick-freezing machine. Background Art

[0002] A quick freezer is a highly efficient freezing device that can freeze a large number of products in a short period of time. The quick freezer mainly performs refrigeration and heat exchange internally through an evaporator and a fan system. In this process, the moisture brought into the food and the moisture lost when the food surface is dried will overflow into the air and frost will form on the fins of the evaporator being cooled. After long-term use, the ventilation channels between the fins will be blocked by frost, causing the evaporator to lose its heat exchange function. At this time, the evaporator needs to be defrosted.

[0003] There are many defrosting methods, among which air defrosting is to spray compressed external air through a nozzle, and the sprayed air blows away the frost on the surface of the evaporator fins.

[0004] However, the nozzle jet range is limited, so the nozzle jet method alone cannot effectively remove the more stubborn frost located in the dead corner, resulting in low defrosting efficiency. In view of this, we propose an air defrosting device for the evaporator of a quick freezer. Utility Model Content

[0008] Preferably, the special-shaped tube is in an inverted U shape, and the special-shaped tube is communicated with the shunt tube.

[0009] Preferably, the plurality of arc-shaped grooves on the inner wall of the heating tube are distributed in an annular manner at intervals, and the heating wire is distributed in a spiral manner in the interlayer of the heating tube.

[0010] Preferably, the frame body comprises a limiting bracket, a fixing ear is provided on a side of the limiting bracket, a collecting bin is fixedly connected to the lower front side of the limiting bracket, and a water pipe is connected to the bottom of the collecting bin.

[0011] Preferably, the jet assembly comprises an air conduit, the air conduit is fixedly connected to the inside of the limiting bracket, and a plurality of nozzles are evenly distributed on the surface of the air conduit.

[0012] Preferably, the inner diameter of the gas collecting pipe gradually decreases from top to bottom, and the upper end of the gas collecting pipe is open and the lower end is closed.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model effectively heats the inside of the heating tube by means of the heating wire, and at the same time, a plurality of arc grooves annularly spaced on the inner wall of the heating tube can effectively increase the contact area with the compressed gas, and the arc grooves effectively extend the transmission path of the compressed airflow inside the heating tube, reduce the flow rate of the compressed airflow, so that the compressed airflow passing through the inside of the heating tube is fully heated, and the heated airflow is ejected to improve the defrosting effect on the evaporator body, and at the same time, the heat can be spread within a certain range, and the more stubborn frost located in the dead corner can also be better removed.

[0015] 2. In the utility model, the air inlet of the air collecting pipe is at the top. Although the amount of gas at the top is large, the volume of the space at the top is large.

[0027] The auxiliary structure 3 includes an air intake pipe 301, a front end of the air intake pipe 301 is connected to a special-shaped pipe 302, a surface of the special-shaped pipe 302 is evenly inserted with a plurality of shunt pipes 303, further, the special-shaped pipe 302 is in an inverted U shape, the special-shaped pipe 302 is connected to the shunt pipe 303, the ends of the special-shaped pipe 302 and the shunt pipe 303 are connected to a heating pipe 304, a plurality of arc grooves 305 are provided on the inner wall of the heating pipe 304, a heating wire 306 is provided in the interlayer of the heating pipe 304, further, the plurality of arc grooves 305 on the inner wall of the heating pipe 304 are distributed in an annular manner, and the heating wire 306 is distributed in a spiral manner in the interlayer of the heating pipe 304. The utility model effectively heats the inside of the heating tube 304 through the heating wire 306. At the same time, the plurality of arc grooves 305 distributed at annular intervals on the inner wall of the heating tube 304 can effectively increase the contact area with the compressed gas. The arc grooves 305 effectively extend the transmission path of the compressed air flow inside the heating tube 304, reduce the flow rate of the compressed air flow, and make the compressed air flow passing through the inside of the heating tube 304 be fully heated. The heated air flow can be ejected to improve the defrosting effect of the evaporator body 1. At the same time, the heat can be spread within a certain range, and the more stubborn frost located in the dead corner can also be better removed.

[0028] It is worth noting that the frame 2 includes a limit bracket 201, a fixing ear 202 is provided on the side of the limit bracket 201, a collection bin 203 is fixedly connected to the lower front side of the limit bracket 201, and a water pipe 204 is connected to the bottom of the collection bin 203. In the utility model, the limit bracket 201 is connected to the evaporator body 1 through the fixing ear 202 and the fastener. After the connection is completed, the collection bin 203 is just located at the bottom of the evaporator body 1, which can effectively collect the water after defrosting and discharge the water through the water pipe 204, without the need for personnel to frequently check and clean.

[0029] It is worth noting that the jet assembly 4 includes an air collecting pipe 401, which is fixed to the inside of the limiting bracket 201, wherein the inner diameter of the air collecting pipe 401 gradually decreases from top to bottom, the upper end of the air collecting pipe 401 is open and the lower end is closed, and a plurality of nozzles 402 are evenly distributed on the surface of the air collecting pipe 401.

At the same time, the arc grooves 305 distributed at intervals on the inner wall of the heating tube 304 can increase the contact area with the compressed gas, and the arc grooves 305 extend the transmission path of the compressed air flow inside the heating tube 304, reduce the flow rate of the compressed air flow, so that the compressed air flow passing through the heating tube 304 is fully heated, and the heated air flow enters The air inlet of the air collecting pipe 401 is at the top. Although the amount of gas at the top is large, the volume of the space at the top is large. Similarly, the amount of gas at the bottom is small, but the volume of the space at the bottom is small. Therefore, the gas pressure value per unit volume remains unchanged, and the upper and lower jet pressure values ​​are effectively maintained consistent. The defrosting effect of the evaporator body 1 can be improved by heating the gas and then spraying it out. At the same time, the heat can spread within a certain range, and the more stubborn frost located in the dead corner can also be better removed. Since the collection bin 203 is located at the bottom of the evaporator body 1, the water after defrosting can be collected and discharged through the water pipe 204, and there is no need for frequent inspection and cleaning by personnel.
