Description

Technical Field

[0001] The utility model belongs to the technical field of defrosting devices, in particular to a defrosting device for a refrigerator in a refrigerated vehicle. Background Art

[0002] A refrigerated truck refers to a closed van transport truck used to maintain the temperature of frozen or fresh goods. A refrigerated truck is a special refrigerated transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment. The normal use of a refrigerated truck is inseparable from the core component, the freezer. After the freezer has been used for a long time, a layer of frost will condense on the surface of the freezer shell, especially at the air outlet of the freezer. In order to ensure the normal use of the freezer, it is often necessary to defrost the freezer regularly. When the existing defrosting device is in use, the cleaning brush and sponge are driven by the driving component to defrost the mesh of the air outlet. Although defrosting can be achieved, the water absorption effect of the sponge will decrease after absorbing a certain amount of water, which will greatly affect the defrosting efficiency, and the cleaning of the sponge is time-consuming and labor-intensive.

[0003] After searching, the Chinese patent document (authorization announcement number CN111238138A) discloses a defrosting device for a refrigerated vehicle freezer, including a refrigerated vehicle, the refrigerated vehicle including a freezer box and a freezer body, the freezer body being installed at the top of the left side of the freezer box inner cavity and the right side of the freezer body being provided with a plurality of air outlet grids equidistantly in the longitudinal direction; the present invention facilitates the design scheme to make linear reciprocating motion on the screw rod through the slide body when in use through the design of the fixed box, motor, screw rod, slide body, vertical fixed block, sponge wiping block bristle brush and water collection tank. Although the patent can realize the defrosting process, the water absorption effect of the sponge will decrease after absorbing a certain degree of water, which will greatly affect the efficiency of defrosting, and the cleaning of the sponge is time-consuming and labor-intensive.

[0011] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0012] The defrosting device for the freezer of the refrigerated truck benefits from the design of the handrail and the drying component. By starting the driving motor to drive the screw to rotate, the rotation of the screw can drive the supporting columns at the bottom ends of the two moving blocks to move up and down in linkage. The adjustment of the supporting columns drives the scraper at the bottom end of the mounting plate and the sponge at the top end to adjust, so as to defrost the freezer body. The handrail is pushed to drive the linkage plate on the side of the linkage block to adjust, and the sponge is squeezed to squeeze out the water stains in the sponge to ensure its water absorption effect. The cleaning operation is more time-saving and labor-saving. The design of the drying component can assist in defrosting the freezer body and can indirectly protect the freezer body.

[0013] The defrosting device for the freezer of the refrigerated truck is convenient for cleaning with a sponge, ensures the water absorption effect of the sponge and the defrosting efficiency, and saves time and effort in cleaning the sponge. BRIEF DESCRIPTION OF THE DRAWINGS
