Description

The lower cover of the refrigerator thermometer and the refrigerator thermometer

technical field

The invention belongs to the technical field of refrigerators, and in particular relates to a lower cover of a refrigerator temperature indicator and a refrigerator temperature indicator.

Background technique

The freezer thermometer is used to show the user the cooling temperature in the freezer to improve the user's experience.

The existing refrigerator temperature display device is a mechanical temperature display device box, as shown in FIG. 1 , including three parts: an upper cover 11, a lower cover 12 and a rear cover 13; wherein, the upper cover 11 is provided with a display window, which is installed in the refrigerator inner tank 2. The position of the punching hole 21 is provided on the outside to display the temperature in the freezer to the user; the lower cover 12 and the rear cover 13 are installed in the cavity between the freezer inner tank 2 and the freezer shell. Specifically, the punching hole 21 of the inner tank of the refrigerator is extended with a flange 211 in the direction of the cavity, and the lower cover 12 of the thermometer can be fixed to the inner tank of the refrigerator by cooperating with the flange 211 of the punching hole 21 through the matching structure design. The back cover 13 of the thermometer is installed on the lower cover 12; space is reserved between the upper cover 11, the punching hole 21 and the lower cover 12, and space is reserved between the rear cover 13 and the lower cover 12, and these spaces are used to accommodate the refrigerator thermometer Other circuit and pipeline connections, etc.

Since the cavity between the inner tank of the refrigerator and the outer shell of the refrigerator needs to be filled with foaming material, in order to prevent the foaming material from entering the inner tank of the refrigerator from the punching hole 21 during the foaming process, when installing the refrigerator thermometer, it is necessary to ensure that the lower part of the refrigerator thermometer is installed. For the sealing between the cover 12 and the punching hole 21, the usual measures are: after the thermometer is installed on the cold valley liner, apply hot melt glue on the joint between the lower cover and the freezer liner, and then use PE tape to seal the hot melt The location where the glue is applied and the entire back cover of the thermometer are wrapped; this sealing method to prevent foaming and flashing is expensive and time-consuming.

A buckle is arranged on the inner side of the hemming; the buckle is buckled into the buckle hole to realize the fixed connection between the back cover and the back cover connecting piece.

A refrigerator thermometer is proposed, which includes an upper cover and a lower cover; the upper cover is installed on the outside of the inner tank of the refrigerator; the inner tank of the refrigerator is provided with punching holes, and the lower cover is installed in the refrigerator facing the punching holes In the cavity between the inner tank and the refrigerator shell; and, along the upper edge of the lower cover, there is an elastic sealing ring body, from the upper edge of the lower cover to the direction of the outer side of the lower cover, the elastic sealing ring The thickness of the body changes from thick to thin.

Compared with the prior art, the advantages and positive effects of the present application are: in the lower cover of the refrigerator thermometer and the refrigerator thermometer proposed by the application, an elastic sealing ring body is provided on the upper edge of the lower cover, and the elastic sealing ring body is from the bottom. The upper edge of the cover is in the direction of the outer side of the lower cover, and its thickness changes from thick to thin. When the lower cover is assembled into the cavity between the inner tank of the refrigerator and the outer shell of the refrigerator, the elastic sealing ring body can fit in the refrigerator. The perimeter of the punching hole on the bladder plays a sealing role. When the foam material is filled into the cavity between the inner bladder of the freezer and the outer shell of the freezer, the elastic sealing ring body blocks the impact force of the foam from the foaming direction and prevents the foaming. In the case of foam overflow, compared with the prior art, after the lower cover is assembled, there is no need to apply hot melt adhesive or PE tape, which reduces costs and saves manpower and assembly time.

Further, by using the method of opening a snap hole on the periphery of the back cover connector, setting the back cover with a hem, and arranging a snap piece on the inner side of the wrap, when the snap piece of the back cover is snapped into the snap button of the back cover connector. After the hole is made, the back cover and the back cover connector are fixed, so that the back cover and the back cover connector form a pipeline that can pass through the temperature sensing probe and the connecting line. The connection of the pipeline is protected by the edge wrapping on the back cover. Moreover, the buckle holes and the buckle parts are located on the inner side of the edging and are also protected by the edging, which ensures that no foaming overflow occurs during the foaming process, and saves the process of wrapping the PE tape on the back cover. This further reduces costs and saves manpower and assembly time.

Further, because the lower cover adopts the design of the elastic sealing ring body, there is no need to refer to the punching and flanging design adopted in the prior art on the periphery of the punching hole of the inner tank of the freezer, but only one punching hole can be opened, so that the freezer can be opened. The inner liner is flat and easy to place, and other materials stacked together will not be scratched due to the existence of flanging, and the deformation caused by flanging during the mutual extrusion process during stacking is also avoided.

Other features and advantages of the present application will become more apparent after reading the detailed description of the embodiments of the present application in conjunction with the accompanying drawings.
