Description

Technical Field

[0001] This application relates to a household appliance, and more particularly to a refrigeration device and a household appliance. Background Technology

[0002] Refrigerators and freezers are common household appliances, with freezers being widely used due to their large storage capacity. To ensure insulation performance, conventional freezers typically use foam insulation to form the cabinet body. Sliding glass doors can be installed at the cabinet opening to allow users to observe the contents and retrieve items from the outside.

[0003] Taking a refrigerator as an example, the refrigerator body and door generally consist of components such as an outer shell and an inner liner. Polyurethane rigid foam is filled between the outer shell and the inner liner to meet insulation requirements, thereby isolating the refrigerator compartment from the outside environment and maintaining a large temperature difference between the inside and outside of the refrigerator. During actual processing, transportation, and use, the refrigerator typically experiences significant temperature changes (maximum range of 80℃ to -30℃), which can easily cause thermal deformation of the body or door, leading to reduced reliability.

[0004] In existing technologies, the common approach to address thermal deformation is to add reinforcing iron to the inner liner. The bending stiffness of this reinforcing iron is typically 10 to 200 times that of the inner liner to meet the requirements for resisting thermal expansion and deformation. For example, in the case of a door, reinforcing iron with a bending stiffness far exceeding that of the inner liner is added to the frame or inner surface of the door's inner liner to enhance overall bending stiffness. However, to meet the bending stiffness requirements of this reinforcing iron, thicker or more complex cross-sectional shapes are needed, leading to increased manufacturing costs. Therefore, designing a technology to reduce thermal deformation in refrigeration equipment to improve reliability and reduce manufacturing costs is the technical problem this application aims to solve.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] In view of the problems pointed out in the background art, this application provides a refrigeration device and a household appliance that reduces the thermal deformation of the refrigeration device to improve its reliability and reduce manufacturing costs.

[0007] To achieve the above-mentioned objectives, this application adopts the following technical solution:

[0008] In some embodiments of this application, a refrigeration device is provided, including:

[0009] outer shell;

[0010] An inner liner is disposed on the outer shell and arranged inside the outer shell;

[0011] A thermal expansion regulating element is disposed on the inner liner and configured to suppress thermal expansion deformation of the inner liner.

[0012] Wherein, the coefficient of thermal expansion of the thermal expansion regulating component is not greater than 0.5 times the coefficient of thermal expansion of the shell, the elastic modulus of the thermal expansion regulating component is not less than 10 times the elastic modulus of the shell, and the elastic modulus of the thermal expansion regulating component is not greater than 100 times the elastic modulus of the shell.

[0013] The above technical solution has the following advantages or beneficial effects: by setting a thermal expansion regulating component on the inner liner, the thermal expansion coefficient of the thermal expansion regulating component is lower than that of the inner liner, and it has a higher elastic modulus than the inner liner. During the thermal deformation process, both the thermal expansion regulating component and the inner liner generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component is smaller than that of the inner liner, the thermal expansion of the inner liner can be effectively reduced by the thermal expansion regulating component, thereby reducing the thermal deformation of the inner liner in the refrigeration equipment, improving the reliability of use, and reducing manufacturing costs.

[0014] Another embodiment of this application also provides a refrigeration device, including:

[0015] A box, wherein a storage space for storing items is formed within the box;

[0017] The door body includes:

[0018] outer shell;

[0019] An inner liner is disposed on the outer shell and arranged inside the outer shell;

[0020] A thermal expansion regulating element is disposed on the inner liner and configured to suppress thermal expansion deformation of the inner liner.

[0021] Wherein, the coefficient of thermal expansion of the thermal expansion regulating component is not greater than 0.5 times the coefficient of thermal expansion of the shell, the elastic modulus of the thermal expansion regulating component is not less than 10 times the elastic modulus of the shell, and the elastic modulus of the thermal expansion regulating component is not greater than 100 times the elastic modulus of the shell.

[0022] The above technical solution has the following advantages or beneficial effects: By setting a thermal expansion regulating component on the inner liner of the door, the thermal expansion regulating component has a lower coefficient of thermal expansion than the inner liner and a higher elastic modulus. During the thermal deformation process, both the thermal expansion regulating component and the inner liner generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component is smaller than that of the inner liner, the thermal expansion of the inner liner can be effectively reduced, thereby reducing the thermal deformation of the door in the refrigeration equipment, improving reliability, and reducing manufacturing costs.

[0023] Another embodiment of this application also provides a refrigeration device, comprising:

[0025] A door, which is mounted on the housing and used to open or close the storage space;

[0026] The enclosure includes:

[0027] outer shell;

[0028] An inner liner is disposed on the outer shell and arranged inside the outer shell;

[0029] A thermal expansion regulating element is disposed on the inner liner and configured to suppress thermal expansion deformation of the inner liner.

[0030] Wherein, the coefficient of thermal expansion of the thermal expansion regulating component is not greater than 0.5 times the coefficient of thermal expansion of the shell, the elastic modulus of the thermal expansion regulating component is not less than 10 times the elastic modulus of the shell, and the elastic modulus of the thermal expansion regulating component is not greater than 100 times the elastic modulus of the shell.

[0031] The above technical solution has the following advantages or beneficial effects: By setting a thermal expansion regulating component on the inner liner of the cabinet, the thermal expansion regulating component has a lower coefficient of thermal expansion than the inner liner and a higher elastic modulus. During the thermal deformation process, both the thermal expansion regulating component and the inner liner generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component is smaller than that of the inner liner, the thermal expansion of the inner liner can be effectively reduced, thereby reducing the thermal deformation of the cabinet in the refrigeration equipment, improving reliability, and reducing manufacturing costs.

[0032] In one embodiment of this application, the thermal expansion regulating member is fixedly connected to the inner liner, and there is no relative displacement between the thermal expansion regulating member and the inner liner. The thermal expansion regulating member is located between the outer shell and the inner liner.

[0033] The above technical solution has the following advantages or beneficial effects: by fixing the thermal expansion regulating component to the inner liner, the thermal expansion regulating component and the inner liner will not produce relative displacement during the thermal expansion process. Thus, during the thermal deformation process, the thermal expansion regulating component and the inner liner deform simultaneously and synchronously, so that the thermal expansion regulating component can play a good role in suppressing the thermal deformation of the inner liner and reduce the amount of thermal deformation of the inner liner.

[0034] In one embodiment of this application, the thermal expansion regulating member is bonded to the inner liner.

[0036] In one embodiment of this application, the thermal expansion regulating member is riveted and fixed to the inner liner.

[0037] The above technical solution has the following advantages or beneficial effects: the thermal expansion regulating component can be directly fixed to the inner liner by riveting, and the thermal expansion regulating component and the inner liner have high connection reliability. Thus, during the process of thermal deformation, the thermal expansion regulating component can effectively suppress the inner liner and reduce the amount of thermal deformation of the inner liner.

[0038] In one embodiment of this application, the thermal expansion regulating member is embedded in the inner liner.

[0039] The above technical solution has the following advantages or beneficial effects: the thermal expansion regulating component is fixed to the inner liner in an embedded manner, and the thermal expansion regulating component and the inner liner can be firmly connected and in full contact. The thermal expansion regulating component plays a better role in suppressing thermal deformation of the inner liner, thereby reducing the amount of thermal deformation generated by the inner liner.

[0040] In one embodiment of this application, the thermal expansion regulating member is integrally sheet-like.

[0041] The above technical solution has the following advantages or beneficial effects: the sheet-like thermal expansion regulating component can reduce the thickness and fit more closely to the inner liner.

[0043] The above technical solution has the following advantages or beneficial effects: the size parameters of the thermal expansion regulating components are all smaller than the size parameters of the inner liner, thereby realizing the reduction of the overall thermal deformation of the inner liner by utilizing the low thermal expansion coefficient and high elastic modulus of the thermal expansion regulating components, thereby reducing the material usage of the thermal expansion regulating components and more effectively reducing manufacturing costs.

[0044] In one embodiment of this application, the thermal expansion regulating member extends along the length direction of the inner liner; or, the thermal expansion regulating member extends along the width direction of the inner liner; or, the thermal expansion regulating member extends obliquely relative to the edge of the inner liner.

[0045] The above technical solution has the following advantages or beneficial effects: the thermal expansion regulating component can be set in the edge or middle area according to the deformation position of the inner liner, so as to effectively suppress the thermal deformation of the corresponding part of the inner liner, thereby minimizing the degree of deformation of the inner liner.

[0047] The above technical solution has the following advantages or beneficial effects: multiple thermal expansion adjustment components are set at the edge or middle of the inner liner to effectively suppress thermal deformation of the inner liner and reduce the amount of thermal deformation of the inner liner.

[0048] In one embodiment of this application, a plurality of thermal expansion adjusting members are provided on the inner liner, and the thermal expansion adjusting members are respectively provided on the edge of the inner liner along the length and / or width directions.

[0049] The above technical solution has the following advantages or beneficial effects: multiple thermal expansion regulating components are distributed and extended along the edge of the inner liner, which can effectively suppress thermal deformation of the inner liner around its perimeter, thereby reducing the amount of thermal deformation at the edge of the inner liner.

[0050] In one embodiment of this application, a plurality of thermal expansion adjusting members are provided on the inner liner, and the thermal expansion adjusting members are respectively provided on the edge of the inner liner and in the middle region of the inner liner.

[0051] The above technical solution has the following advantages or beneficial effects: multiple thermal expansion regulating components are distributed on the edge and middle of the inner liner. The thermal expansion regulating components in the middle can suppress the thermal deformation in the middle region of the inner liner, while the thermal expansion regulating components distributed on the edge of the inner liner can further suppress thermal deformation around the inner liner, thereby reducing the overall thermal deformation of the inner liner.

[0052] In one embodiment of this application, positioning portions are provided at both ends of the thermal expansion regulating member, and positioning mating portions that cooperate with the positioning portions are provided on the inner liner, and the positioning portions are connected together with the corresponding positioning mating portions.

[0053] The above technical solution has the following advantages or beneficial effects: by providing positioning parts at both ends of the thermal expansion regulating component, and correspondingly providing positioning mating parts on the inner liner, during the process of assembling the thermal expansion regulating component into the inner liner, the positioning parts will connect with the positioning mating parts at the corresponding positions, thereby enabling the thermal expansion regulating component to be installed accurately and reliably in place, so as to play a good role in suppressing thermal deformation at the corresponding positions of the inner liner.

[0054] In one embodiment of this application, the surface of the thermal expansion regulating member conforms to the surface of the inner liner.

[0055] The above technical solution has the following advantages or beneficial effects: the surface contour of the thermal expansion regulating component matches the surface contour of the inner liner, so that the thermal expansion regulating component can fit more tightly against the inner liner, so that different positions of the inner liner can obtain the inhibitory effect of the thermal expansion regulating component during the thermal deformation process, thereby reducing the overall thermal deformation of the inner liner.

[0056] In one embodiment of this application, the length of the inner liner is L1, the width is H1, and the thickness is T1;

[0057] The thermal expansion regulating component has a length of L2, a width of H2, and a thickness of T2.

[0059] Among them, A nd T represents the maximum projected area of ​​the inner liner. nd The average thickness of the inner liner is given.

[0060] The above technical solution has the following advantages or beneficial effects: the size of the thermal expansion regulating component is designed according to the size of the inner liner so that the efficiency coefficient of the thermal expansion regulating component is greater than the preset threshold. In this way, it can be ensured that the thermal expansion regulating component has a sufficiently strong regulating effect to meet the adjustment requirements of the inner liner to prevent thermal deformation.

[0061] In one embodiment of this application, L2 ≥ 2 / 3 times L1, 1 / 8 times H1 ≤ H2, H2 ≤ 1 / 4 times H1, 1 / 5 times T1 ≤ T2, and / or T2 ≤ 1 times T1.

[0062] The above technical solution has the following advantages or beneficial effects: In the process of designing the overall size of the thermal expansion regulating component, while meeting the requirements of suppressing thermal deformation, the overall size of the thermal expansion regulating component is reasonably designed to reduce manufacturing costs.

[0063] Another embodiment of this application also provides a household appliance, including:

[0067] The above technical solution has the following advantages or beneficial effects: by setting a thermal expansion regulating component on the shell, the thermal expansion coefficient of the thermal expansion regulating component is lower than that of the shell, and it has a higher elastic modulus than the shell. During the thermal deformation process, both the thermal expansion regulating component and the shell generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component is smaller than that of the shell, the thermal expansion of the shell can be effectively reduced by the thermal expansion regulating component, thereby improving the reliability of use and reducing the manufacturing cost.

[0091] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0093] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0094] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0097] The refrigeration equipment in this application typically includes a cabinet, a door, and a refrigeration system. The cabinet contains at least one refrigeration compartment, which is opened and closed via a door to meet the requirements for storing and retrieving items.

[0098] The refrigeration system executes a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle comprises a series of processes involving compression, condensation, expansion, and evaporation to cool the items inside the cabinet.

[0099] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0100] The expansion valve causes the high-temperature, high-pressure liquid refrigerant that condenses in the condenser to expand into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator can cool the items inside the cabinet by utilizing the latent heat of refrigerant evaporation.

[0101] like Figures 1-3 As shown, one embodiment of this application provides a refrigeration device, including:

[0102] Outer shell 1;

[0103] Inner liner 2, the inner liner 2 is disposed on the outer shell 1, the inner liner 2 is arranged inside the outer shell 1, and a heat insulation layer is formed between the inner liner 2 and the outer shell 1;

[0104] A thermal expansion regulating component 3 is disposed on the inner liner 2 and is configured to suppress thermal expansion deformation of the inner liner 2.

[0105] Specifically, the coefficient of thermal expansion of the thermal expansion regulating component 3 is lower than that of the inner liner 2, and the elastic modulus of the thermal expansion regulating component 3 is higher than that of the inner liner 2. Specifically, the coefficient of thermal expansion of the thermal expansion regulating component 3 is not greater than 0.5 times that of the inner liner 2, the elastic modulus of the thermal expansion regulating component 3 is not less than 10 times that of the inner liner 2, and the elastic modulus of the thermal expansion regulating component is not greater than 100 times that of the inner liner 2.

[0106] Specifically, this application provides a refrigeration device in which the inner liner 2 of the refrigeration device is arranged inside the outer shell 1, and the refrigeration device forms a storage cavity that can store items and keep the stored items refrigerated and stored at a temperature lower than the ambient temperature.

[0107] In one embodiment, the coefficient of thermal expansion of the thermal expansion regulating member 3 is not greater than 0.3 times the coefficient of thermal expansion of the inner liner 2.

[0108] Specifically, the thermal expansion regulating element 3 has a lower coefficient of thermal expansion, resulting in less thermal deformation during thermal expansion and contraction, thereby providing better bending protection for the inner liner 2. In some embodiments, the ratio of the coefficient of thermal expansion of the thermal expansion regulating element 3 to that of the inner liner is 0.1 to 0.3.

[0109] In one embodiment, the ratio of the elastic modulus of the thermal expansion regulating member 3 to the elastic modulus of the inner liner 2 is between 80 and 100.

[0110] Specifically, the thermal expansion regulating component 3 has a high elastic modulus, and thus has good elastic deformation capacity during the process of resisting thermal deformation. Combined with the low thermal expansion coefficient of the thermal expansion regulating component 3, it ensures that the thermal expansion regulating component 3 can adapt to the deformation of the inner liner 2 and undergo elastic deformation accordingly. On the other hand, it relies on the small amount of thermal deformation of the thermal expansion regulating component 3 itself to suppress the deformation of the inner liner 2.

[0111] As for the inner liner 2, it will be affected by the low temperature environment inside the storage cavity, which will cause the inner liner 2 to deform due to large temperature differences during use.

[0112] In order to reduce the amount of thermal expansion deformation of the inner liner 2 due to temperature difference, a thermal expansion regulating component 3 is added to the inner liner 2. The thermal expansion regulating component 3 will suppress the deformation of the inner liner 2 by relying on its own properties of low expansion coefficient and high elastic modulus.

[0113] Specifically, after the thermal expansion regulating component 3 is installed on the inner liner 2, during the process of thermal deformation of the inner liner 2 due to temperature changes, the thermal expansion regulating component 3 also undergoes thermal deformation simultaneously with the inner liner 2. However, due to the low coefficient of thermal expansion and high elastic modulus of the thermal expansion regulating component 3, the small deformation of the thermal expansion regulating component 3 is used to suppress the overall deformation of the inner liner 2.

[0114] In actual use, the thermal expansion regulating component 3 reduces the deformation of the inner liner 2 by relying on its low coefficient of expansion and high elastic modulus, rather than by its own bending stiffness. This allows the overall thickness of the thermal expansion regulating component 3 to be made thinner, so that the cross-sectional shape of the thermal expansion regulating component 3 is simpler, without the need to design a complex cross-sectional shape to increase the bending stiffness, thereby achieving the requirement of reducing manufacturing costs.

[0115] Furthermore, even though the bending stiffness of the thermal expansion regulating component 3 is much lower than that of conventional reinforcing iron—for example, the bending stiffness of the thermal expansion regulating component 3 is less than that of the inner liner, and even less than that of conventional reinforcing iron—during use, the thermal expansion regulating component 3 does not rely on its own bending stiffness to suppress the thermal deformation of the inner liner 2. Instead, it relies on the small coefficient of thermal expansion of the thermal expansion regulating component 3 to reduce its own thermal deformation. Because the elastic modulus of the thermal expansion regulating component 3 is higher than that of the inner liner 2, it suppresses the thermal deformation of the inner liner 2, thereby meeting the requirement of reducing the overall deformation of the inner liner 2.

[0116] In one embodiment, the bending stiffness of the thermal expansion regulating member 3 is not less than 0.04 times the bending stiffness of the inner liner 2, and the bending stiffness of the thermal expansion regulating member 3 is not greater than 1 time the bending stiffness of the inner liner 2.

[0117] In practical use, because the coefficient of thermal expansion of the thermal expansion regulating component 3 is lower than that of the inner liner 2, and the bending stiffness of the thermal expansion regulating component 3 is no greater than that of the inner liner, the suppression of thermal deformation of the inner liner 2 mainly relies on the low coefficient of thermal expansion of the thermal expansion regulating component 3 to reduce the deformation of the inner liner 2, rather than relying on the bending stiffness of the thermal expansion regulating component 3 itself. This allows the overall thickness of the thermal expansion regulating component 3 to be made thinner, resulting in a simpler cross-sectional shape, eliminating the need for a complex cross-sectional shape to increase bending stiffness, thereby reducing manufacturing costs.

[0118] In one embodiment, the bending stiffness of the thermal expansion regulating member 3 is not greater than 0.15 times the bending stiffness of the inner liner 2, and the bending stiffness of the thermal expansion regulating member 3 is not less than 0.04 times the bending stiffness of the inner liner 2.

[0119] Specifically, while the bending stiffness of the thermal expansion regulating component 3 is less than that of the inner liner 2, the bending stiffness value of the thermal expansion regulating component 3 is not less than 0.04 times the bending stiffness of the inner liner 2, so that the thermal expansion regulating component itself has sufficient bending stiffness to meet the requirement of suppressing thermal deformation of the inner liner.

[0120] In this way, during use, the low coefficient of thermal expansion of the thermal expansion regulating component 3 can suppress thermal deformation of the inner liner 2 while ensuring that the thermal expansion regulating component 3 remains in an effective state.

[0121] The following example illustrates this. The bending stiffness ratio of the thermal expansion regulating component 3, made of carbon steel, to the inner liner 2 is 0.04~1.0. For example, it is 0.04~0.15 for galvanized steel or Q235 steel, and the efficiency coefficient is 0.1~0.3.

[0122] The bending stiffness ratio of the thermal expansion regulating component 3, made of copper alloy, to the inner liner 2 is 0.02~0.6. For example, it is 0.02~0.15 for H70 industrial brass plate, and the efficiency coefficient is 0.15~0.3.

[0123] The thermal expansion regulating component 3, made of aluminum alloy, has a bending stiffness ratio of 0.01 to 0.5 compared to the inner liner 2. For example, the ratio for 5052 aluminum plate is 0.02 to 0.15, and the efficiency coefficient is 0.2 to 0.4.

[0124] The thermal expansion regulating component 3 uses a composite material with a bending stiffness ratio of 0.01 to 0.5 compared to the inner liner 2. For example, the ratio for glass fiber reinforced plastic board is 0.02 to 0.15, and the efficiency coefficient is 0.3 to 0.4.

[0125] For the inner liner 2 and the thermal expansion regulating component 3, both can be regarded as isotropic materials. The inner liner 2 and the thermal expansion regulating component 3 are firmly connected and have no relative displacement. Their deformation is synchronous.

[0126] Assuming a uniform temperature change, with a temperature difference of ∆T before and after the change. According to the thermal expansion formula, the deformation of the thermal expansion regulating component 3 and the inner liner 2 is:

[0127]

[0128] in:

[0129] —The amount of deformation that occurs in the thermal expansion adjustment component along the direction of expansion and contraction;

[0130] —The amount of deformation of the inner liner along the direction of expansion and contraction;

[0131] —Stress in thermal expansion regulating components;

[0132] —The coefficient of thermal expansion of the thermal expansion regulating component;

[0133] —Stress in the inner liner;

[0134] —Coefficient of thermal expansion of the inner liner;

[0135] —The elastic modulus of the thermal expansion regulating component;

[0136] —The elastic modulus of the inner liner;

[0137] —Equivalent coefficient of thermal expansion of the system consisting of the inner liner and thermal expansion regulating components;

[0138] —The length of the system consisting of the inner liner and the thermal expansion regulating components;

[0139] —The amount of deformation along the expansion and contraction direction of the system consisting of the inner liner and the thermal expansion regulating component.

[0140] According to formulas (1) and (2), the strains of the thermal expansion regulating component 3 and the inner liner 2 can be obtained as follows:

[0141]

[0142] In the formula , The strains are those of the thermal expansion regulating component 3 and the inner liner 2, respectively.

[0143] From the above equation, it can be seen that the thermal deformation of the thermal expansion regulating component 3 and the inner liner 2 during temperature change mainly includes two parts: one is the thermal strain caused by the thermal deformation of the thermal expansion regulating component 3 and the inner liner 2; the other is the strain caused by stress due to the different thermal expansion coefficients of the thermal expansion regulating component 3 and the inner liner 2. Since the inner liner 2 system is in static equilibrium during temperature change, we can obtain:

[0144]

[0145] in, The cross-sectional area of ​​thermal expansion regulating component 3 is... Let be the cross-sectional area of ​​the inner liner 2. During temperature changes, the thermal expansion regulating component 3 and the inner liner 2 are bonded together, therefore:

[0146]

[0147] Combining equations (3~8), we get:

[0148]

[0149] Substituting formula (9) into formula (3), we can obtain the deformation of the refrigerator door 200 during the foaming and cooling process:

[0150]

[0151] Assuming the widths of the thermal expansion regulating component 3 and the inner liner 2 are the same, and the thickness of the inner liner 2 is typically 0.5~2.0mm, the elastic modulus of the material used for the thermal expansion regulating component 3 is... Much larger Coefficient of thermal expansion much smaller The thickness of the thermal expansion regulating component 3 is between 0.2mm and 1.0mm. The coefficient of thermal expansion of the system composed of the inner liner 2 and the thermal expansion regulating component 3 is... ≈ At this point, the thermal variation of the inner liner 2 is greatly reduced, which indicates that the thermal expansion regulating component 3 can be a very thin plate structure, and the structural strength of the thermal expansion regulating component 3 has little effect on the thermal variation of the inner liner 2.

[0152] By installing a thermal expansion regulating component 3 on the inner liner 2, the coefficient of thermal expansion of the regulating component 3 is lower than that of the inner liner 2, and it also has a higher elastic modulus. During thermal deformation, both the regulating component 3 and the inner liner 2 experience corresponding thermal deformation. However, since the thermal expansion of the regulating component 3 is smaller than that of the inner liner 2, the thermal expansion of the inner liner 2 can be effectively reduced. This reduces the amount of thermal deformation of the inner liner 2 in the refrigeration equipment, thereby improving reliability and reducing manufacturing costs. (Reference) Figure 21 and Figure 22 It can be seen that the deformation range of the inner liner 2 using the thermal expansion regulating component 3 is smaller, and the area with larger deformation (the dark area in the figure) is effectively suppressed; compared with the conventional technology that uses reinforced iron to resist deformation, Figure 21 The deformation range is relatively large, and the area with larger deformation is also larger.

[0153] In one embodiment of this application, such as Figures 1-3 As shown, for a refrigeration device, the refrigeration device includes a housing 100, in which a storage space for storing items is formed.

[0154] The refrigeration equipment includes a door 200, which is disposed on the housing 100 and used to open or close the storage space.

[0155] The door body 200 includes an outer shell 1 and an inner liner 2. The inner liner 2 is disposed on the outer shell 1 and arranged inside the outer shell 1. An insulation layer is formed between the inner liner 2 and the outer shell 1.

[0156] In addition, the door body 200 includes a thermal expansion regulating member 3, which is disposed on the inner liner 2. The thermal expansion regulating member 3 is configured to suppress thermal expansion deformation of the inner liner 2. The coefficient of thermal expansion of the thermal expansion regulating member 3 is lower than the coefficient of thermal expansion of the inner liner 2, and the elastic modulus of the thermal expansion regulating member 3 is higher than the elastic modulus of the inner liner 2.

[0157] Specifically, this application provides a refrigeration device in which a storage cavity is formed in the housing 100 of the refrigeration device. The storage cavity is capable of storing items and refrigerating the stored items at a temperature lower than the ambient temperature.

[0158] The door 200 of the refrigeration equipment can open and close the storage cavity, and the inner liner 2 of the door 200 is arranged inside the outer shell 1. The inner liner 2 will be affected by the low temperature environment inside the storage cavity, and will deform due to large temperature differences during use.

[0159] In order to reduce the amount of thermal expansion deformation of the inner liner 2 due to temperature difference, a thermal expansion regulating component 3 is added to the inner liner 2. The thermal expansion regulating component 3 will suppress the deformation of the inner liner 2 by relying on its own properties of low expansion coefficient and high elastic modulus.

[0160] Specifically, after the thermal expansion regulating component 3 is installed on the inner liner 2, during the opening and closing of the door 200, the inner liner 2 of the door 200 will undergo thermal deformation due to the temperature difference between the low temperature inside the cabinet 100 and the ambient temperature outside the cabinet 100. At the same time, the thermal expansion regulating component 3 on the door 200 also undergoes thermal deformation along with the inner liner 2. However, due to the low coefficient of thermal expansion and high modulus of elasticity of the thermal expansion regulating component 3, the small deformation of the thermal expansion regulating component 3 is used to suppress the overall deformation of the inner liner 2.

[0161] In actual use, since the thermal expansion regulating component 3 relies on its low expansion coefficient and high elastic modulus to reduce the deformation of the inner liner 2, rather than on its own bending stiffness, the overall thickness of the thermal expansion regulating component 3 can be made thinner, so that the cross-sectional shape of the thermal expansion regulating component 3 is simpler, and there is no need to design a complex cross-sectional shape to increase the bending stiffness, thereby achieving the requirement of reducing the manufacturing cost of the door body 200.

[0162] Furthermore, even though the bending stiffness of the thermal expansion regulating component 3 is much lower than that of conventional reinforcing iron, for example, the bending stiffness of the thermal expansion regulating component 3 is less than 0.01 times that of the reinforcing iron, the thermal expansion regulating component 3 has a low coefficient of thermal expansion, resulting in a small amount of thermal deformation. This, in turn, simultaneously suppresses the amount of thermal deformation of the inner liner 2 connected to the thermal expansion regulating component 3, thus meeting the requirement of reducing the overall deformation of the inner liner 2.

[0163] By setting a thermal expansion regulating component 3 on the inner liner 2 of the door body 200, the thermal expansion regulating component 3 has a lower coefficient of thermal expansion than the inner liner 2 and a higher elastic modulus than the inner liner 2. During the thermal deformation process, both the thermal expansion regulating component 3 and the inner liner 2 will generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component 3 is smaller than that of the inner liner 2, the thermal expansion of the inner liner 2 can be effectively reduced by the thermal expansion regulating component 3, thereby reducing the thermal deformation of the door body 200 in the refrigeration equipment, improving the reliability of use and reducing manufacturing costs.

[0164] In one embodiment of this application, such as Figures 1-3 As shown, for a refrigeration device, the refrigeration device includes a housing 100, in which a storage space for storing items is formed.

[0165] The refrigeration equipment includes a door 200, which is disposed on the cabinet 100 and used to open or close the storage space;

[0166] The housing 100 includes an outer shell 1 and an inner liner 2. The inner liner 2 is disposed on the outer shell 1 and arranged inside the outer shell 1. An insulation layer is formed between the inner liner 2 and the outer shell 1.

[0167] In addition, the housing 100 also has a thermal expansion regulating member 3, which is disposed on the inner liner 2 and is configured to suppress thermal expansion deformation of the inner liner 2.

[0168] The coefficient of thermal expansion of the thermal expansion regulating component 3 is lower than that of the inner liner 2, and the elastic modulus of the thermal expansion regulating component 3 is higher than that of the inner liner 2.

[0169] Specifically, the refrigeration device provided in this application has a storage cavity formed in the housing 100 of the refrigeration device. The storage cavity can store items and allows the stored items to be refrigerated and stored at a temperature lower than the ambient temperature. The inner liner 2 of the housing 100 will be affected by the low temperature environment inside the storage cavity, and will deform during use due to large temperature differences.

[0170] In order to reduce the amount of thermal expansion deformation of the inner liner 2 due to temperature difference, a thermal expansion regulating component 3 is added to the inner liner 2. The thermal expansion regulating component 3 will suppress the deformation of the inner liner 2 by relying on its own properties of low expansion coefficient and high elastic modulus.

[0171] Specifically, after the thermal expansion regulating component 3 is installed on the inner liner 2, during the thermal deformation of the inner liner 2 of the box 100 due to temperature difference, the thermal expansion regulating component 3 on the inner liner 2 also undergoes thermal deformation simultaneously with the inner liner 2. However, due to the low coefficient of thermal expansion and high modulus of elasticity of the thermal expansion regulating component 3, the small deformation of the thermal expansion regulating component 3 is used to suppress the overall deformation of the inner liner 2.

[0172] In actual use, since the thermal expansion regulating component 3 relies on its low expansion coefficient and high elastic modulus to reduce the deformation of the inner liner 2, rather than on its own bending stiffness, the overall thickness of the thermal expansion regulating component 3 can be made thinner, so that the cross-sectional shape of the thermal expansion regulating component 3 is simpler, and there is no need to design a complex cross-sectional shape to increase the bending stiffness, thereby achieving the requirement of reducing the manufacturing cost of the box 100.

[0173] Furthermore, even though the bending stiffness of the thermal expansion regulating component 3 is much lower than that of conventional reinforcing iron, for example, the bending stiffness of the thermal expansion regulating component 3 is less than 0.01 times that of the reinforcing iron, the thermal expansion regulating component 3 has a high elastic modulus, resulting in a smaller amount of thermal deformation. This, in turn, simultaneously suppresses the amount of thermal deformation of the inner liner 2 connected to the thermal expansion regulating component 3, thus meeting the requirement of reducing the overall deformation of the inner liner 2.

[0174] By providing a thermal expansion regulating component 3 on the inner liner 2 of the housing 100, the thermal expansion regulating component 3 has a lower coefficient of thermal expansion than the inner liner 2 and a higher elastic modulus than the inner liner 2. During the thermal deformation process, both the thermal expansion regulating component 3 and the inner liner 2 generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component 3 is smaller than that of the inner liner 2, the thermal expansion of the inner liner 2 can be effectively reduced by the thermal expansion regulating component 3, thereby reducing the thermal deformation of the housing 100 in the refrigeration equipment, improving the reliability of use, and reducing manufacturing costs.

[0175] In one embodiment of this application, the thermal expansion regulating member 3 is fixedly connected to the inner liner 2, and the thermal expansion regulating member 3 and the inner liner 2 have no relative displacement. The thermal expansion regulating member 3 is located between the outer shell 1 and the inner liner 2.

[0176] The thermal expansion regulating element 3 and the inner liner 2 are configured to deform synchronously.

[0177] Specifically, after the thermal expansion regulating component 3 is connected to the inner liner 2, there will be no relative displacement between the thermal expansion regulating component 3 and the inner liner 2 during use. This ensures a strong and reliable connection between the thermal expansion regulating component 3 and the inner liner 2. Furthermore, when the inner liner 2 undergoes thermal expansion deformation due to temperature differences, the thermal expansion regulating component 3 can effectively suppress deformation at the connection points of the inner liner 2, thereby minimizing the amount of thermal deformation of the inner liner 2.

[0178] Meanwhile, the thermal expansion regulating element 3 is located between the inner liner 2 and the outer shell 1 to ensure that the thermal expansion regulating element 3 can be built into the interior and to ensure that the thermal expansion regulating element 3 and the inner liner 2 maintain an effective and reliable connection.

[0179] By fixing the thermal expansion regulating component 3 to the inner liner 2, the thermal expansion regulating component 3 and the inner liner 2 will not have relative displacement during the thermal expansion process. Thus, during the thermal deformation process, the thermal expansion regulating component 3 and the inner liner 2 deform simultaneously and synchronously. This allows the thermal expansion regulating component 3 to effectively suppress the thermal deformation of the inner liner 2 and reduce the amount of thermal deformation of the inner liner 2.

[0180] In one embodiment, the thermal expansion regulating member 3 is bonded to the inner liner 2.

[0181] Specifically, the thermal expansion regulating component 3 can be bonded and fixed to the inner liner 2 using double-sided tape or adhesive glue. This effectively improves the assembly efficiency of the thermal expansion regulating component 3 during the actual assembly process. The adhesive method ensures that all parts of the thermal expansion regulating component 3 are firmly and tightly attached to the inner liner 2.

[0182] The thermal expansion regulating component 3 can be bonded and fixed to the inner liner 2 by means of double-sided tape or adhesive, so that the thermal expansion regulating component 3 can be quickly and firmly fixed to the inner liner 2, and the thermal expansion regulating component 3 and the inner liner 2 can be firmly and reliably attached together, thereby better suppressing thermal deformation of the inner liner 2 through the thermal expansion regulating component 3.

[0183] In one embodiment of this application, the thermal expansion adjusting member 3 is riveted and fixed to the inner liner 2.

[0184] Specifically, the thermal expansion regulating component 3 can be fixed to the inner liner 2 by riveting. In the actual assembly process, multiple rivets can be used to connect the thermal expansion regulating component 3 to the inner liner 2 along its length. The riveting connection method allows the thermal expansion regulating component 3 to be connected to the inner liner 2 more firmly and reliably.

[0185] The thermal expansion regulating component 3 can be directly fixed to the inner liner 2 by riveting. The thermal expansion regulating component 3 and the inner liner 2 have high connection reliability. Therefore, during the process of thermal deformation, the thermal expansion regulating component 3 can effectively suppress the inner liner 2 and reduce the amount of thermal deformation generated by the inner liner 2.

[0186] In one embodiment of this application, the thermal expansion regulating member 3 is embedded in the inner liner 2.

[0187] Specifically, for the inner liner 2, the thermal expansion regulating component 3 can be directly embedded within the inner liner 2 during the manufacturing process. Thus, after the inner liner 2 is formed, the thermal expansion regulating component 3 is assembled and connected to it. This ensures a tighter and more reliable connection between the thermal expansion regulating component 3 and the inner liner 2, and also saves labor time in later assembly of the thermal expansion regulating component 3 and the inner liner 2.

[0188] Furthermore, since the thermal expansion regulating component 3 is embedded in the inner liner 2, the reliability of the combination between the two is higher, so that the thermal expansion regulating component 3 can improve the thermal deformation resistance of the inner liner 2 and reduce the thermal deformation of the inner liner 2.

[0189] The above technical solution has the following advantages or beneficial effects: the thermal expansion regulating component 3 is fixed to the inner liner 2 by being embedded, and the thermal expansion regulating component 3 and the inner liner 2 can be firmly connected and in full contact. The thermal expansion regulating component 3 plays a better role in suppressing thermal deformation of the inner liner 2, thereby reducing the amount of thermal deformation generated by the inner liner 2.

[0190] In one embodiment of this application, the thermal expansion regulating member 3 is generally in the form of a sheet structure.

[0191] Specifically, while ensuring that the thermal expansion regulating component 3 reduces the amount of thermal deformation of the inner liner 2, the thickness of the thermal expansion regulating component 3 is relatively thin to reduce manufacturing costs. The bending stiffness of the thermal expansion regulating component 3 itself has a relatively small effect on the thermal deformation resistance of the inner liner 2. The thermal deformation of the inner liner 2 is still reduced by the low coefficient of thermal expansion and high modulus of elasticity of the thermal expansion regulating component 3 itself. Unlike the complex structures that require special design using structural reinforcement components in the prior art, the use of a sheet-like thermal expansion regulating component 3 is sufficient to meet the requirements for reducing the amount of thermal deformation of the inner liner 2.

[0192] In one embodiment, the thickness of the thermal expansion regulating member 3 is less than the thickness of the inner liner 2.

[0193] Specifically, the thickness of the thermal expansion regulating component 3 is less than the thickness of the inner liner 2, which reduces the amount of material used in the thermal expansion regulating component 3 and is more conducive to reducing manufacturing costs.

[0194] In one embodiment, the length of the thermal expansion regulating member 3 is less than the length of the inner liner 2.

[0195] Specifically, such as Figures 2-3As shown, the inner liner 2 is prone to thermal expansion deformation along its length. The thermal expansion regulating element 3 is distributed along the edge of the inner liner 2 and extends along its length. The length of the thermal expansion regulating element 3 is less than the length of the inner liner 2, so that the thermal expansion regulating element 3 is distributed within the surface formed by the inner liner 2. While satisfying the requirement of reducing thermal deformation of the inner liner 2, the thermal expansion regulating element 3 does not extend to the outside of the inner liner 2, thus not changing the overall shape of the inner liner 2.

[0196] In this way, if the inner liner 2 is prone to thermal deformation in the length direction, the thermal expansion adjustment component 3 is extended and distributed along the length direction of the inner liner 2.

[0197] For example, the thermal expansion adjustment component 31 should be installed in a flat and easy-to-attach position near the inner liner 2 of the frame. The length L of the thermal expansion adjustment component 31 should be ≥ 2 / 3 of the height of the inner liner 2. The thermal expansion adjustment component 3 on one side can be a whole strip or segmented, but the spacing between segmented thermal expansion adjustment components 3 should be < 10mm.

[0198] In one embodiment, the length of the thermal expansion regulating member 3 is less than the width of the inner liner 2.

[0199] Specifically, such as Figure 4 and Figure 5 As shown, the inner liner 2 is prone to thermal expansion deformation along its width. The thermal expansion regulating member 3 is distributed along the edge of the inner liner 2 and extends along its width. The length of the thermal expansion regulating member 3 is less than the width of the inner liner 2, so that the thermal expansion regulating member 3 is distributed within the surface formed by the inner liner 2. While satisfying the requirement of reducing thermal deformation of the inner liner 2, the thermal expansion regulating member 3 does not extend to the outside of the inner liner 2, thus not changing the overall shape of the inner liner 2.

[0200] In this way, if the inner liner 2 is prone to thermal deformation in the width direction, the thermal expansion adjustment element 3 is distributed along the length direction of the inner liner 2.

[0201] For example, the thermal expansion adjustment component 3 should be installed in a flat and easy-to-stick position near the inner liner 2 of the frame. The length L of the thermal expansion adjustment component 3 should be ≥ 2 / 3 of the width of the inner liner 2. The thermal expansion adjustment component 3 on one side can be a whole strip or segmented, but the spacing between segmented thermal expansion adjustment components 3 should be < 10mm.

[0202] In one embodiment, at least one of the thermal expansion regulating members 3 is provided on the inner liner 2, and the thermal expansion regulating member 3 extends along the length and width directions of the inner liner 2.

[0203] By setting the thermal expansion regulating component 3 as a sheet structure, it can better adhere to the surface of the inner liner 2. The size parameters of the thermal expansion regulating component 3 are all smaller than the size parameters of the inner liner 2. Thus, the low thermal expansion coefficient and high elastic modulus of the thermal expansion regulating component 3 can be used to reduce the overall thermal deformation of the inner liner 2, thereby reducing the material usage of the thermal expansion regulating component 3 and more effectively reducing manufacturing costs.

[0204] Meanwhile, the thermal expansion regulating component 3 can be set in the edge or middle area according to the deformation position of the inner liner 2, so as to effectively suppress the thermal deformation of the corresponding part of the inner liner 2, thereby minimizing the degree of deformation of the inner liner 2.

[0205] In another embodiment, the inner liner 2 is provided with a plurality of thermal expansion adjusting members 3, and the edge of the inner liner 2 is provided with the thermal expansion adjusting members 3 along the length and / or width directions respectively.

[0206] Specifically, such as Figure 8 and Figure 9 As shown, the edges of the inner liner 2 are prone to deformation due to thermal expansion. Thermal expansion adjustment components 3 can be arranged on the edges of the inner liner 2.

[0207] Multiple thermal expansion regulating elements 3 are distributed and extended along the edge of the inner liner 2, which can effectively suppress thermal deformation of the inner liner 2 around its perimeter, thereby reducing the amount of thermal deformation at the edge of the inner liner 2.

[0208] For example, the thermal expansion adjustment component 3 is installed in a flat, easy-to-adhere position near the inner liner 2, close to the frame. The length L of the thermal expansion adjustment component 3 along the length direction of the inner liner 2 is ≥ 2 / 3 of the length of the inner liner 2. The thermal expansion adjustment component 3 on one side can be a single strip or segmented, but the spacing between segmented thermal expansion adjustment components 3 must be < 10mm. Similarly, the length L of the thermal expansion adjustment component 3 along the width direction of the inner liner 2 is ≥ 2 / 3 of the width of the inner liner 2. The thermal expansion adjustment component 3 on one side can be a single strip or segmented, but the spacing between segmented thermal expansion adjustment components 3 must be < 10mm.

[0209] In another embodiment, the thermal expansion regulating member 3 is arranged in the central region of the inner liner 2.

[0210] Specifically, such as Figure 6 and Figure 7 As shown, for the inner liner 2, there is a problem that the central area of ​​the inner liner 2 is severely deformed due to thermal expansion and contraction. To address this, a thermal expansion regulating component 3 can be placed in the central area of ​​the inner liner 2 to effectively resist thermal deformation in the central area of ​​the inner liner 2.

[0211] Normally, when thermal deformation occurs in the central area of ​​the inner liner 2, thermal deformation will also occur at the edges of the inner liner 2.

[0212] In one embodiment of this application, a plurality of thermal expansion regulating members 3 are provided on the inner liner 2, and the thermal expansion regulating members 3 are respectively provided on the edge of the inner liner 2 and in the middle region of the inner liner 2.

[0213] like Figure 10 and Figure 11 As shown, after arranging the thermal expansion regulating element 3 in the central region of the inner liner 2, it is further possible to arrange the thermal expansion regulating element 3 along the length direction of the inner liner 2 at its edge. Alternatively, as... Figure 12 As shown, the thermal expansion regulating member 3 extends along the diagonal direction of the inner liner 2 to reduce the deformation of the inner liner 2 in the length direction and the middle part by means of the inclined thermal expansion regulating member 3.

[0214] Or, such as Figure 13 and Figure 14 As shown in the figure, after the thermal expansion regulating member 3 is arranged in the middle region of the inner liner 2, it can be further arranged along the width direction of the inner liner 2 at the edge of the inner liner 2.

[0215] Or, such as Figure 15 and Figure 16 As shown in the figure, after the thermal expansion adjustment component 3 is arranged in the middle region of the inner liner 2, it can be further arranged around the inner liner 2, along the length and width directions of the inner liner 2, at the edge of the inner liner 2.

[0216] The above technical solution has the following advantages or beneficial effects: multiple thermal expansion regulating elements 3 are distributed on the edge and middle of the inner liner 2. The thermal expansion regulating elements 3 in the middle can suppress the thermal deformation in the middle region of the inner liner 2, while the thermal expansion regulating elements 3 distributed on the edge of the inner liner 2 can further suppress thermal deformation around the inner liner 2, thereby reducing the overall thermal deformation of the inner liner 2.

[0217] In one embodiment of this application, as Figure 17 As shown, the two ends of the thermal expansion regulating member 3 are respectively provided with positioning parts 31, and the inner liner 2 is provided with positioning mating parts that cooperate with the positioning parts 31. The positioning parts 31 are connected together with the corresponding positioning mating parts.

[0218] Specifically, to facilitate the installation of the positioning thermal expansion adjusting component 3, positioning parts 31 are provided at both ends of the thermal expansion adjusting component 3, and positioning mating parts that match and are installed on the inner liner 2 are provided. During assembly, the positioning parts 31 are connected to the positioning mating parts to achieve positioning.

[0219] In actual use, the positioning part 31 can be a positioning hole formed at both ends of the thermal expansion regulating member 3, and the corresponding positioning mating part is a protrusion formed on the inner liner 2. The protrusion will be inserted into the positioning hole to realize the pre-positioned assembly of the thermal expansion regulating member 3 and the inner liner 2.

[0220] Alternatively, the positioning part 31 can be a protrusion formed at both ends of the thermal expansion regulating member 3, and the inner liner 2 is provided with a positioning groove, with the protrusion inserted into the positioning groove, so as to realize the pre-positioned assembly of the thermal expansion regulating member 3 and the inner liner 2.

[0221] By providing positioning parts 31 at both ends of the thermal expansion regulating component 3, and correspondingly providing positioning mating parts on the inner liner 2, during the process of assembling the thermal expansion regulating component 3 into the inner liner 2, the positioning parts 31 will connect with the positioning mating parts at the corresponding positions, thereby enabling the thermal expansion regulating component 3 to be installed accurately and securely in place, so as to play a good role in suppressing thermal deformation at the corresponding positions of the inner liner 2.

[0222] In one embodiment of this application, the surface of the thermal expansion regulating member 3 conforms to the surface of the inner liner 2.

[0223] Specifically, the surface contour of the inner liner 2 is not necessarily completely flat. As for the thermal expansion adjustment component 3 installed on the inner liner 2, in order to meet the requirement of effective fit with the inner liner 2, the thermal expansion adjustment component 3 is also designed to conform to the surface contour of the inner liner 2. In this way, the thermal expansion adjustment component 3 can fit more effectively and tightly with the inner liner 2.

[0224] like Figure 18 As shown, the thermal expansion regulating component 3 is provided with spaced-apart strip-shaped protrusions, which match the strip-shaped recesses on the inner liner 2. Figure 19 As shown, the thermal expansion regulating component 3 is provided with spaced-apart spherical protrusions, which will match the spherical recesses on the inner liner 2. Figure 20 As shown, the thermal expansion regulating member 3 is provided with a columnar protrusion structure extending along the length direction, which will match the columnar recess structure formed on the inner liner 2.

[0225] Similarly, a recessed structure can be provided on the thermal expansion adjustment component 3 to match the protruding structure formed on the inner liner 2. There are no restrictions on the specific conformal design.

[0226] The surface contour of the thermal expansion regulating component 3 matches the surface contour of the inner liner 2, so that the thermal expansion regulating component 3 can fit more tightly against the inner liner 2. During the thermal deformation process, different positions of the inner liner 2 can be inhibited by the thermal expansion regulating component 3, thereby reducing the overall thermal deformation of the inner liner 2.

[0227] In one embodiment of this application, the inner liner 2 has a length of L1, a width of H1, and a thickness of T1;

[0228] The thermal expansion regulating component 3 has a length of L2, a width of H2, and a thickness of T2.

[0229] L2 ≥ 2 / 3 times L1, 1 / 8 times H1 ≤ H2, H2 ≤ 1 / 4 times H1, 1 / 5 times T1 ≤ T2, and / or T2 ≤ 1 times T1;

[0230] The efficiency coefficient β of the thermal expansion regulating component 3 is ≥0.1, β= (2×L2×H2×T2) / (A nd ×T nd );

[0231] Among them, A nd T is the maximum projected area of ​​the inner liner 2. nd The average thickness of the inner liner 2.

[0232] Specifically, according to the above formula β = (2 × L² × H² × T²) / (A) nd ×T nd It can be seen that the thermal expansion regulating component 3 plays a role in adjusting the coefficient of thermal expansion. The larger the coefficient, the stronger the adjustment effect of the coefficient of thermal expansion.

[0233] The upper limit of the efficiency coefficient β of the thermal expansion regulating component 3 is less than 1.

[0234] For example: 0.1 < β < 0.3. The efficiency coefficient β of the above-mentioned thermal expansion regulating component 3 can not only meet the performance requirements of thermal expansion regulating component 3 in resisting thermal deformation, but also take into account the cost requirements, so as to ensure that the inner liner 2 obtains good thermal deformation protection from thermal expansion regulating component 3 while reducing manufacturing costs.

[0235] When designing the dimensions of the thermal expansion regulating component 3, the dimensions of the thermal expansion regulating component 3 can be designed according to the above formula and the dimensions of the inner liner 2 to be processed.

[0236] In designing the overall dimensions of the thermal expansion regulating component 3, it is necessary to meet the requirements of suppressing thermal deformation on the one hand, and to consider the processing requirements of reducing manufacturing costs on the other hand. Therefore, the dimensions of the thermal expansion regulating component 3 are designed according to the dimensions of the inner liner 2, so that the efficiency coefficient of the thermal expansion regulating component 3 is greater than the preset threshold. In this way, it can be ensured that the thermal expansion regulating component 3 has a sufficiently strong regulating effect to meet the regulation requirements of the inner liner 2 to prevent thermal deformation.

[0237] Another embodiment of this application also provides a household appliance, including:

[0238] case;

[0239] A thermal expansion regulating component 3 is disposed on the inner liner 2 and is configured to suppress thermal expansion deformation of the inner liner 2.

[0240] The coefficient of thermal expansion of the thermal expansion regulating component 3 is lower than that of the shell, and the elastic modulus of the thermal expansion regulating component 3 is higher than that of the shell.

[0241] Specifically, for ordinary household appliances, where the casing is largely made of plastic, the casing may undergo significant thermal expansion and deformation due to temperature changes during prolonged use.

[0242] Therefore, in order to reduce the large amount of thermal deformation of the shell due to temperature, a thermal expansion regulating component 3 can also be provided on the shell.

[0243] Specifically, after the thermal expansion regulating component 3 is installed on the shell, during the process of thermal deformation of the shell due to temperature changes, the thermal expansion regulating component 3 also undergoes thermal deformation simultaneously with the shell. However, due to the low coefficient of thermal expansion and high elastic modulus of the thermal expansion regulating component 3, the small deformation of the thermal expansion regulating component 3 is used to suppress the overall deformation of the shell.

[0244] The physical manifestations of household appliances can be conventional household appliances such as air conditioners, humidifiers, and washing machines.

[0245] By setting a thermal expansion regulating component 3 on the shell, the thermal expansion regulating component 3 has a lower coefficient of thermal expansion than the shell and a higher elastic modulus than the shell. During the thermal deformation process, both the thermal expansion regulating component 3 and the shell generate corresponding thermal deformation. Since the thermal expansion of the thermal expansion regulating component 3 is smaller than that of the shell, the thermal expansion of the shell can be effectively reduced, thereby improving the reliability of use and reducing manufacturing costs.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
