Description

Refrigerating equipment and household appliance Technical Field The present application relates to a household appliance, and more particularly, to a refrigeration apparatus and a household appliance. Background The refrigerator and the freezer are household appliances commonly used in daily life, and the freezer is widely popularized and used due to the large storage capacity. In order to ensure heat preservation performance, a cabinet body of a conventional refrigerator usually adopts a foaming mode to form a heat preservation layer, and a sliding glass door can be arranged on a cabinet opening of the cabinet body according to requirements to meet the requirements of users for observing storage conditions in the cabinet body and taking articles. Taking a refrigerator as an example, a refrigerator body and a door body of the refrigerator generally comprise an outer shell, an inner container body and other parts, and polyurethane hard foam is filled between the outer shell and the inner container body to meet the heat preservation requirement, so that a refrigerator compartment is isolated from the outside, and a larger temperature difference between the inside and the outside of the refrigerator is kept. In actual processing, transportation and use, large temperature change (the maximum temperature is 80 ℃ to minus 30 ℃) is usually experienced, and the case body or the door body is easy to generate thermal deformation, so that the use reliability is reduced. In order to solve the problem of thermal deformation, a method of adding reinforcing iron to the liner is generally used in the prior art. The bending rigidity of the reinforced iron is 10-200 times of that of the liner body, so that the requirement of thermal expansion deformation can be met. Taking a door body as an example, the frame or the inner surface of the inner container body of the door body is added with reinforcing iron with bending rigidity far greater than that of the inner container body, and the whole bending rigidity is enhanced by the reinforcing iron. However, in order to meet the requirement of the bending rigidity of the reinforcing iron, a thicker reinforcing iron or a reinforcing iron having a complicated sectional shape is required to meet the requirement of the bending rigidity, which results in an increase in manufacturing cost. In view of this, it is an object of the present application to design a technique for reducing the thermal deformation amount of a refrigeration apparatus to improve the reliability of use and reduce the manufacturing cost. The above information disclosed in this background section is only for enhancement of understanding of the background section of the application and therefore it may not form the prior art that is already known to those of ordinary skill in the art. Disclosure of utility model In view of the problems pointed out in the background art, the present application provides a refrigeration apparatus and a household appliance, which realize reduction of the thermal deformation amount of the refrigeration apparatus to improve the use reliability and reduce the manufacturing cost. In order to achieve the purposes of the application, the application is realized by adopting the following technical scheme: in some embodiments of the present application, there is provided a refrigeration apparatus including: an outer housing; The inner container body is arranged on the outer shell body, and the inner container body is arranged on the inner side of the outer shell body; A thermal expansion adjustment member provided on the inner container body, the thermal expansion adjustment member being configured to exert an effect of suppressing thermal expansion deformation on the inner container body; Wherein the thermal expansion coefficient of the thermal expansion adjusting member is not more than 0.5 times the thermal expansion coefficient of the housing, the elastic modulus of the thermal expansion adjusting member is not less than 10 times the elastic modulus of the housing, and the elastic modulus of the thermal expansion adjusting member is not more than 100 times the elastic modulus of the housing. The technical scheme has the advantages that the thermal expansion adjusting piece is arranged on the inner container body, the thermal expansion coefficient of the thermal expansion adjusting piece is lower than that of the inner container body, the thermal expansion adjusting piece has higher elastic modulus than that of the inner container body, in the process of generating thermal deformation, the thermal expansion adjusting piece and the inner container body generate corresponding thermal deformation, and the thermal expansion adjusting piece is smaller than that of the inner container body, so that the thermal expansion amount of the inner container body can be effectively reduced through the thermal expansion adjusting piece, and the thermal deformation of the inner container body in refrigeration
