Description

Refrigerator

Technical Field

The utility model belongs to the technical field of refrigeration equipment, and particularly relates to a refrigerator.

Background

Along with improvement of resident living standard and environmental awareness, household appliances are increasingly developed towards the direction of high energy efficiency and low power consumption, and if the refrigerator products want to improve energy efficiency, a large technical route is to increase the thickness of a foaming layer, but increasing the thickness of the foaming layer can lead to a large refrigerator body, and the refrigerator body has low net volume rate and seems heavier. Therefore, a vacuum insulation panel (VIP panel for short) with better heat insulation is often selected to replace part of the foaming layer, that is, the VIP panel is placed in the box/door body, and then the foaming material is injected to expect that the foaming material combines the shell, the liner and the VIP panel into a whole.

In the prior art, the VIP board is usually fixed by using double faced adhesive tape or a bracket. Specifically, when the VIP plate is fixed in the door body, the double faced adhesive tape is adhered to the VIP plate, and then the VIP is adhered to the door shell, but the VIP plate foaming material does not contact the door shell in the scheme, the good heat insulation performance of the VIP can lead to the fact that the side mold temperature of the door shell is reduced when foaming so as to be unfavorable for continuous foaming, and meanwhile, the design has higher requirements on operators, and the door shell is folded at the VIP edge when the foaming material is cooled and contracted after the foaming is caused by poor adhesion of the double faced adhesive tape at the edge. When the bracket is adopted to fix, the VIP plate is suspended, the door shell and the door liner side are filled with foaming materials, so that the problem can be solved, but the scheme is that the foaming materials can only be injected from one side, so that the foaming materials can flow into the other side to avoid cavitation, the VIP plate is split into at least 2 blocks, a foaming material flow path is reserved in the middle of the door shell, the door shell cannot be fully paved by the VIP plate, the energy efficiency cannot be improved maximally, the foaming materials flow and expand at the door liner side firstly, flow to the door shell side later, and the foaming materials on the door shell side are easy to cause insufficient foaming materials on the door shell side to cause cavitation on the door shell side. Meanwhile, the bracket is required to be stuck on the door shell by using double faced adhesive tape, more labor is wasted, and the edge flanging problem can be generated if the manual sticking is poor.

Specifically, mounting slots 1121 are formed on the left and right sides of the back plate 112, mounting pieces 1111 are formed on the connection plate 1115, the mounting pieces 1111 are adapted to be connected with the mounting slots 1121, and the bending plate 111 is inserted into the mounting slots 1121 through the mounting pieces 1111, so that the bending plate 111 is joined with the back plate 112 to form a side surface of the case 1. Wherein, the mounting sheet 1111 is formed by folding the connecting plate 1115 toward the inside of the case 1.

Referring to fig. 5, the case side plate is provided with a mounting opening 114, and the case 1 further includes a hood panel 52 attached to the mounting opening 114 to block the mounting opening 114. In this embodiment, the cabin cover plate 52 is provided with a plurality of heat dissipation openings 521, and heat generated by the operation of the compressor is conducted out of the casing 1 through the plurality of heat dissipation openings 521.

According to the refrigerator 100 provided by the utility model, the clamping piece 24 used for clamping the first vacuum insulation board 3 is fixedly arranged on the inner side surface of the door end cover 23, so that the first vacuum insulation board 3 is fixed by the door end covers 23 at two ends; through setting up honeycomb duct 6 on case shell 11, carry out spacingly to the second vacuum insulation board 17 of installing in case shell 11, improved the installation fixed mode of first vacuum insulation board 3, second vacuum insulation board 17, improve simultaneously that door body 2 and box 1 annotate bubble mode and foaming material flow mode, can effectively solve the VIP board and lead to door body 2, box deformation problem, improve simultaneously and annotate the bubble mode for foaming material flows and distributes more evenly, can effectively improve the mould temperature and reduce, the uneven, foaming material cavitation scheduling problem of cooling.

Finally, it should be noted that: in the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
