Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a refrigerator. Background Technology

[0002] Refrigerators are widely used in daily life. To meet different temperature requirements, refrigerators typically have a refrigerator compartment and a freezer compartment. The temperature in the refrigerator compartment is higher than that in the freezer compartment, allowing different items to be stored in each. In some technologies, the same refrigeration system cools both the refrigerator and freezer compartments simultaneously. This method can lead to insufficient cooling capacity in either compartment, resulting in poor cooling performance. Furthermore, the freezer compartment is usually a single unit, meaning the entire freezer can only maintain a single temperature. Utility Model Content

[0043] Refrigerators are widely used in daily life. To meet different temperature requirements, refrigerators typically have a refrigerator compartment and a freezer compartment. The temperature in the refrigerator compartment is higher than that in the freezer compartment, allowing different items to be stored in each compartment. In related technologies, the same refrigeration system is used to cool both the refrigerator and freezer compartments simultaneously. This method can lead to insufficient cooling capacity in either compartment, resulting in poor cooling performance. Furthermore, the freezer compartment is usually a single unit, meaning it can only reach a single temperature throughout. The refrigerator provided in this application allows both the first and second freezer compartments to cool independently, thereby improving the cooling effect of both the refrigerator and freezer compartments.

[0044] This application is described below with reference to the accompanying drawings and specific embodiments:

[0045] Figure 1 A schematic diagram of the structure of the refrigerator 100 provided in an embodiment of this application is shown, as follows: Figure 1 As shown, this application embodiment provides a refrigerator 100, which enables the first freezer compartment 114 and the second freezer compartment 114 to be cooled independently, thereby improving the cooling effect of the refrigerator compartment 112 and the freezer compartment 114.

[0046] Figure 2 This shows a structural schematic diagram of the refrigerator 100 excluding the door 120 from a first-view perspective. Figure 3 It shows Figure 2Sectional view at point AA. Figure 4 It shows Figure 2 A sectional view at point BB, as shown Figure 2 , Figure 3 and Figure 4 As shown in the embodiment of this application, the refrigerator 100 includes: a cabinet 110, a door 120, a first air duct module 130 and a second air duct module 140. The cabinet 110 has a refrigerator compartment 112 and a freezer compartment 114. The door 120 is rotatably connected to the cabinet 110.

[0047] The first air duct module 130 is installed in the refrigerator compartment 112. The first air duct module 130 includes a first housing 132, a first evaporator 134 and a first fan 136. The first housing 132 is connected to the cabinet 110. The first housing 132 has a first receiving cavity 132a and a refrigerator air outlet 132b and a refrigerator air return vent 132c that communicate with the first receiving cavity 132a. The first evaporator 134 and the first fan 136 are both installed in the first receiving cavity 132a. The refrigerator air outlet 132b and the refrigerator air return vent 132c are both connected to the refrigerator compartment 112.

[0048] The second air duct module 140 is installed in the freezer compartment 114. The freezer compartment 114 includes a first freezer cavity 114a and a second freezer cavity 114b that are independent of each other. The second air duct module 140 includes a second housing 142, a second evaporator 144 and a second fan 146. The second housing 142 is connected to the cabinet 110. The second housing 142 has a second receiving cavity 142a and a first freezer air outlet 1421b, a second freezer air outlet 1423b, a first freezer air return outlet 1421c and a second freezer air return outlet 1423c that are connected to the second receiving cavity 142a. The second evaporator 144 and the second fan 146 are both installed in the second receiving cavity 142a. The first freezer air outlet 1421b and the first freezer air return outlet 1421c are both connected to the first freezer cavity 114a. The second freezer air return outlet 1423c and the second freezer air outlet 1423b are both connected to the second freezer cavity 114b.

[0049] The cabinet 110 is the basic component of the entire refrigerator 100, serving as its main structure. It provides the foundation for the installation of structures such as the first air duct module 130 and the second air duct module 140, enabling the refrigerator 100 to function as a single unit and facilitating its transportation. The cabinet 110 may include an outer shell 116 and an inner liner. The inner liner is disposed inside the outer shell 116, and the inner liner and outer shell 116 can be connected via foaming. Both the refrigerator compartment 112 and the freezer compartment 114 are located within the inner liner. In some embodiments, the inner liner may include a refrigerator inner liner 117 and a freezer inner liner 118, with the refrigerator compartment 112 located within the refrigerator inner liner 117 and the freezer compartment 114 located within the freezer inner liner 118.

[0050] The box 110 is roughly rectangular and has a height direction Z, a width direction X, and a depth direction Y. For ease of description, in the use state, the vertical direction is defined as the height direction Z, the direction of the door 120 towards the inside of the box 110 is defined as the depth direction Y, and the width direction X, the height direction Z, and the depth direction Y are all set perpendicularly.

[0051] The refrigerator compartment 112 and the freezer compartment 114 are two independent chambers. The first air duct module 130 is installed in the refrigerator compartment 112 to supply air to the refrigerator compartment 112 so that the refrigerator compartment 112 can cool. The second air duct module 140 is installed in the freezer compartment 114 to supply air to the freezer compartment 114 so that the freezer compartment 114 can cool.

[0052] It is easy to understand that the refrigerator 100 also includes a compressor, a condenser, and a throttling valve. The compressor, condenser, throttling valve, and first evaporator 134 can form one refrigeration circuit, and the compressor, condenser, throttling valve, and second evaporator 144 can form another refrigeration circuit. That is, the first evaporator 134 and the second evaporator 144 can be connected in parallel, or the compressor, condenser, throttling valve, first evaporator 134, and second evaporator 144 can all form one refrigeration circuit, that is, the first evaporator 134 and the second evaporator 144 can be connected in series. In other words, the first evaporator 134 and the second evaporator 144 can be connected in series or in parallel, and the specific method is not limited.

[0053] The first air duct module 130 includes a first evaporator 134 and a first fan 136. The first evaporator 134 can be connected to the condenser, so that the air in the refrigerator compartment 112 can enter the first receiving cavity 132a through the refrigerator return air vent 132c. After being cooled by the first evaporator 134, it is blown out from the refrigerator air outlet 132b, so that the cold air can circulate in the refrigerator compartment 112.

[0054] Since cold air can move downwards under the influence of gravity, the refrigeration air outlet 132b can be set above the refrigeration return air outlet 132c, so that the cold air can flow from top to bottom and fill the entire refrigeration compartment 112 as much as possible.

[0055] Similarly, the second air duct module 140 includes a second evaporator 144 and a second fan 146. The second evaporator 144 can be connected to the condenser, so that the air in the freezer compartment 114 can enter the second receiving cavity 142a through the freezer return air port 142c. After being cooled by the second evaporator 144, the air is blown out from the freezer outlet 142b, so that the cold air can circulate in the freezer compartment 114.

[0056] The first air duct module 130 and the second air duct module 140 each have independent evaporators, which enable the refrigerator compartment 112 and the freezer compartment 114 to have independent refrigeration systems. The cooling capacity between the refrigerator compartment 112 and the freezer compartment 114 is minimized so as to prevent mutual interference, allowing the refrigerator compartment 112 and the freezer compartment 114 to cool independently, thereby improving the cooling effect of the refrigerator compartment 112 and the freezer compartment 114.

[0057] The freezer compartment 114 has two independent first freezer chambers 114a and 114b. Both the first freezer air outlet 1421b and the first freezer air return vent 1421c are connected to the first freezer chamber 114a, allowing cold air to circulate within it. Similarly, the second freezer air outlet 1423b and the second freezer air return vent 1423c are connected to the second freezer chamber 114b, allowing cold air to circulate within it as well. Because the first and second freezer chambers 114a and 114b are independent, and the damper 150 can open or close the first air outlet 132d, the first freezer chamber 114a can be a wide-range variable temperature chamber. The amount of cold air entering the first freezer chamber 114a can be adjusted by regulating the opening of the damper 150, thereby regulating the temperature of the first freezer chamber 114a. This allows users to adjust the temperature of the first freezer chamber 114a according to their needs, improving the user experience.

[0058] In some embodiments, the second air duct module 140 may be disposed in the middle of the freezer compartment 114, and the freezer compartment 114 may be divided into a first freezer cavity 114a and a second freezer cavity 114b by the second air duct module 140. Alternatively, the second air duct module 140 may also be disposed on one side of the freezer compartment 114 along the width direction X of the cabinet 110. For ease of description, the example of the second air duct module 140 being disposed in the middle of the freezer compartment 114 will be used for illustration.

[0059] In some embodiments, the second refrigeration air outlet 1423b is disposed on the side wall of the second housing 142, and the first refrigeration air outlet 1421b is disposed on the top wall of the second housing 142.

[0060] Since the first freezing chamber 114a and the second freezing chamber 114b are independently configured, that is, the first freezing air outlet 1421b and the second freezing air outlet 1423b are independent air outlets, in order to avoid mutual interference between the first freezing air outlet 1421b and the second freezing air outlet 1423b, the first freezing air outlet 1421b and the second freezing air outlet 1423b can be set on different sides of the second housing 142. The first freezing air outlet 1421b can be set on the top wall of the second housing 142, and the second freezing air outlet 1423b can be set on the side wall of the second housing 142, so that the first freezing air outlet 1421b and the second freezing air outlet 1423b can emit air independently, reducing airflow interference and improving the cooling effect.

[0061] Figure 5 A structural schematic diagram of the refrigerator 100 excluding the door 120 is shown from a second perspective, as follows. Figure 5 As shown, in some embodiments, the second air duct module 140 further includes a first air outlet 147, which includes a first air outlet section 147h and a second air outlet section 147f that are interconnected. The first air outlet section 147h is connected to the first refrigeration air outlet 1421b, and the second air outlet section 147f is connected to the first refrigeration chamber 114a. The first air outlet section 147h is disposed at the top of the first refrigeration chamber 114a, and the second air outlet section 147f is disposed on the rear wall of the second refrigeration chamber 114b.

[0062] Since the first refrigeration air outlet 1421b is located on the top wall of the second housing 142, and the first refrigeration cavity 114a is located on one side of the second housing 142, in order to guide cold air to the first refrigeration cavity 114a, a first air outlet 147 is provided between the first refrigeration air outlet 1421b and the first refrigeration cavity 114a. The first air outlet section 147h can be located at the top of the first refrigeration cavity 114a, and the second air outlet section 147f is located along the height direction Z of the housing 110 and fixed to the rear wall of the second refrigeration cavity 114b, so that the cold air in the first refrigeration cavity 114a can blow from back to front and from top to bottom, thereby improving the cooling effect of the first refrigeration cavity 114a.

[0063] The damper 150 can be installed on the second housing 142 or on the first air outlet 147. The specific installation position of the damper 150 is not limited, as long as it can be opened and closed the first refrigeration air outlet 1421b.

[0064] In some embodiments, the housing 110 includes an outer shell 116 and a freezing inner liner 118. The first freezing chamber 114a and the second freezing chamber 114b are both disposed in the freezing inner liner 118. The first air outlet section 147h is disposed outside the freezing inner liner 118 and passes through the freezing inner liner 118.

[0065] Since the first refrigeration air outlet 1421b is located at the top of the second housing 142, in order to facilitate the arrangement of the first air outlet section 147h, the first air outlet section 147h can be located outside the refrigeration inner liner 118 and pass through the refrigeration inner liner 118 to communicate with the second air outlet section 147f.

[0066] The first air outlet section 147h can be set at an angle to the second air outlet section 147f, so that the cold air blown out from the top of the second housing 142 can be blown into the first freezing chamber 114a from one side.

[0067] Figure 6 It shows Figure 2 A magnified view of a section at point II, as shown below. Figure 6 As shown, in some embodiments, the second air outlet section 147f has a first air outlet 147a, which extends along the width direction X of the housing 110. The second air outlet section 147f can be integrally formed with the second housing 142, and the first air outlet 147a can be located at the corner between the second housing 142 and the rear wall of the first freezing cavity 114a. The first air outlet 147a is arranged along the width direction X of the housing 110, so that the air blown from the first air outlet 147a can be directed towards the other side wall of the first freezing cavity 114a, so that the cold air can flow as evenly as possible within the first freezing cavity 114a, thereby improving the cooling effect.

[0068] In some embodiments, the rear wall of the first freezing chamber 114a is provided with a first air guide surface 147b, and the first air outlet 147a extends to the first air guide surface 147b. The first air guide surface 147b can be inclined so that the cold air blown out from the first air outlet 147a can be blown to a farther place, thereby improving the cooling effect of the first freezing chamber 114a.

[0069] Specifically, a first positioning part 147c can be provided in the first freezer compartment 114. The first positioning part 147c can abut against the second air outlet section 147f to fix the second air outlet section 147f. A first air guide surface 147b can be provided on the first positioning part 147c. Using the first positioning part 147c to set the first air guide surface 147b can make the structure inside the first freezer cavity 114a more compact.

[0070] As for the number of first air outlets 147a, multiple first air outlets 147a can be set. Multiple first air outlets 147a are set along the height of the cabinet 110 so that cold air can be blown to different heights of the first freezer compartment 114, thereby improving the cooling effect.

[0071] Figure 7 It shows Figure 2 A magnified view of a section at point III, as shown below. Figure 7As shown, in some embodiments, the second air duct module 140 further includes a second air outlet 148, which connects the second refrigeration air outlet 1423b and the second refrigeration chamber 114b. The second air outlet 148 is installed on the rear wall of the second refrigeration chamber 114b. The second air outlet 148 can be integrally formed with the second housing 142, which facilitates the assembly of the entire second air duct. The second air outlet 148 is disposed on the rear wall of the second refrigeration chamber 114b, which facilitates the arrangement of the second air outlet 148.

[0072] In some embodiments, the second air outlet 148 is provided with a second air outlet 148a, which is provided along the width direction X of the housing 110.

[0073] The second air outlet 148 can be integrally formed with the second housing 142, and the second air inlet 148a can be located at the corner of the rear wall of the second housing 142 and the second freezing chamber 114b. The second air inlet 148a is arranged along the width direction X of the housing 110, so that the air blown out from the second air inlet 148a can be blown towards the other side wall of the second freezing chamber 114b, so that the cold air can flow evenly in the second freezing chamber 114b as much as possible, thereby improving the cooling effect.

[0074] In some embodiments, the second air outlet 148a can extend to the second housing 142, that is, the second air outlet 148a can be directly connected to the second refrigeration air outlet 1423b, and the cold air blown out from the second refrigeration air outlet 1423b can flow directly to the second air outlet 148a and blow directly into the second refrigeration chamber 114b, reducing the air outlet path.

[0075] In some embodiments, the rear wall of the second freezing chamber 114b is provided with a second air guide surface 148b, and the second air outlet 148a extends to the second air guide surface 148b. The second air guide surface 148b can be inclined so that the cold air blown out from the second air outlet 148a can be blown to a farther place, thereby improving the cooling effect of the second freezing chamber 114b.

[0076] Specifically, a second positioning part 148c can be provided in the second freezer compartment 114. The second positioning part 148c can abut against the second air outlet section 147f to fix the second air outlet section 147f. The second air guide surface 148b can be provided on the second positioning part 148c. Using the second positioning part 148c to set the second air guide surface 148b can make the structure inside the second freezer compartment 114b more compact.

[0077] As for the number of second air outlets 148a, multiple outlets can be set. Multiple second air outlets 148a are set along the height of the cabinet 110 so that cold air can be blown to different heights of the second chamber, thereby improving the cooling effect.

[0078] Figure 8 It shows Figure 4 A magnified view of a portion of IV, as shown below. Figure 8 As shown, regarding the air outlet configuration of the second fan 146, the second fan 146 can be positioned above the second evaporator 144. The second fan 146 may include a second volute 146a and a second impeller 146b. The second impeller 146b is installed inside the second volute 146a. A second air inlet 146c, a first refrigeration air outlet 146d, and a second refrigeration air outlet 146f can be provided on the second volute 146a. The first refrigeration air outlet 146d communicates with the first air outlet 147a, and the second refrigeration air outlet 146f communicates with the second air outlet 148a. The first refrigeration air outlet 146d is located on the top wall of the second volute 146a, and the second refrigeration air outlet 146f is located on the rear wall of the second volute 146a.

[0079] In some embodiments, the thickness of the door 120 is 25mm-40mm, specifically, the thickness of the door 120 can be 26mm, 28mm, 30mm, 35mm, 38mm, etc. The total thickness of the cabinet 110 and the door 120 is 450mm-600mm. The total thickness of the cabinet 110 and the door 120 can be 460mm, 480mm, 500mm, 550mm, 580mm, etc. The thickness of the door 120 refers to the thickness in the depth direction Y of the cabinet 110. Similarly, the total thickness of the cabinet 110 and the door 120 refers to the total thickness in the depth direction Y of the cabinet 110, making the entire refrigerator 100 an ultra-thin refrigerator 100, which can be embedded in narrow spaces such as sideboards and cabinets.

[0080] Please see Figure 3 and Figure 4 In some embodiments, the refrigerated air outlet 132b and the refrigerated air return outlet 132c are disposed on the side wall of the first housing 132. The first air duct module 130 can be disposed on one of the side walls of the refrigerator compartment 112 or in the middle of the refrigerator compartment 112. Whether disposed on the side wall or in the middle of the refrigerator compartment 112, the first air duct module 130 does not occupy the space behind the cabinet 110, that is, it does not occupy the dimension of the cabinet 110 in the depth direction Y, thereby reducing the thickness of the entire cabinet 110 and making the entire refrigerator 100 more compact.

[0081] The side wall of the first housing 132 refers to one side of the first housing 132 along the width direction X of the box 110. The refrigeration air outlet 132b and the refrigeration air return outlet 132c are set on one side of the first housing 132, so that the cold air blown out from the refrigeration air outlet 132b can circulate in the refrigeration compartment 112 and then be blown out from the refrigeration air return outlet 132c.

[0082] In some embodiments, the first air duct module 130 is disposed in the refrigerator compartment 112, dividing the refrigerator compartment 112 into a first refrigerator cavity 112a and a second refrigerator cavity 112b, and a refrigerator air outlet 132b and a refrigerator air return outlet 132c are provided on both sides of the first housing 132.

[0083] Specifically, the first air duct module 130 may be located in the middle of the refrigerator compartment 112, so that the volumes of the first refrigerator compartment 112a and the second refrigerator compartment 112b are approximately the same, or the first air duct module 130 may be located close to the side wall of one of the compartments 110, so that the volumes of the first refrigerator compartment 112a and the second refrigerator compartment 112b may be different.

[0084] Both sides of the first housing 132 are provided with a refrigeration air outlet 132b and a refrigeration air return outlet 132c, that is, the first refrigeration cavity 112a and the second refrigeration cavity 112b each have a separate refrigeration air outlet 132b and a refrigeration air return outlet 132c, so that the first refrigeration cavity 112a and the second refrigeration cavity 112b can each take in and return air independently, so that the take in and return air of the first refrigeration cavity 112a and the second refrigeration cavity 112b are not affected by each other, thereby enabling the first refrigeration cavity 112a and the second refrigeration cavity 112b to work independently and improve the refrigeration effect.

[0085] In other words, for ease of description, the left chamber of the refrigerator compartment 112 is defined as the first refrigerator compartment 112a, and the right chamber as the second refrigerator compartment 112b. Since the first air duct module 130 is located in the middle of the refrigerator compartment 112, the left side wall of the first air duct module 130 is configured as a wall of the first refrigerator compartment 112a, and the right side wall of the first air duct module 130 is configured as a wall of the second refrigerator compartment 112b. Both the first refrigerator compartment 112a and the second refrigerator compartment 112b are provided with a refrigerator return air vent 132c and a refrigerator air outlet 132b. That is, the left side wall of the first housing 132 is provided with a refrigerator return air vent 132c and a refrigerator air outlet 132b, and the right side wall of the first housing 132 is also provided with a refrigerator return air vent 132c and a refrigerator air outlet 132b.

[0086] To facilitate the description of the specific locations of the refrigerated air outlet 132b and the refrigerated air return vent 132c, the following description will focus on a specific arrangement of the refrigerated air outlet 132b and the refrigerated air return vent 132c in one of the first refrigerated chambers 112a and 112b. The same principle applies when the refrigerated air outlet 132b and the refrigerated air return vent 132c are located in another chamber. Specifically, the description will focus on the location and arrangement of the refrigerated air outlet 132b and the refrigerated air return vent 132c within the first refrigerated chamber 112a. The same principle applies when the refrigerated air outlet 132b and the refrigerated air return vent 132c are located in the second refrigerated chamber 112b. All the arrangements listed below refer to the arrangement of the refrigerated air outlet 132b and the refrigerated air return vent 132c within the first refrigerated chamber 112a.

[0087] In some embodiments, there are multiple refrigeration air outlets 132b, which are spaced apart along the height direction Z of the first housing 132. This arrangement of multiple refrigeration air outlets 132b at different heights within the first refrigeration cavity 112a allows cold air to be blown to different heights within the first cavity, thereby ensuring more uniform cooling and improving the refrigeration effect.

[0088] In some embodiments, the refrigerated air outlet 132b includes a first air outlet 132d and a second air outlet 132e. The first air outlet 132d is located above the second air outlet 132e. The first air outlet 132d is arranged along the depth direction Y of the cabinet 110, and the second air outlet 132e is arranged along the height direction Z of the cabinet 110.

[0089] Both the first air outlet 132d and the second air outlet 132e are elongated. The first air outlet 132d is positioned along the depth direction Y of the housing 110, meaning its length is aligned with the depth direction Y of the housing 110, i.e., it is positioned front and back. This allows the first air outlet 132d to cover a large area in the depth direction Y of the housing 110. Furthermore, since the first air outlet 132d is positioned above the second air outlet 132e, it can be close to the top wall of the first refrigeration chamber 112a. This allows the air blown from the first air outlet 132d to travel from the top wall of the first refrigeration chamber 112a to the bottom wall, thus enabling the cold air to circulate throughout the entire first refrigeration chamber 112a and improving its cooling effect.

[0090] Similarly, since the first air outlet 132d is set along the depth direction Y, the first air outlet 132d has a large coverage area in the depth direction Y of the cabinet 110, so that the cold air blown out from the first air outlet 132d can be blown to a farther place (as far as possible to the other side wall of the first refrigeration cavity 112a), thereby enabling the cold air to circulate in the entire first refrigeration cavity 112a and improving the cooling effect in the first refrigeration cavity 112a.

[0091] The second air outlet 132e is set along the height direction Z of the cabinet 110, that is, the length direction of the second air outlet 132e is set along the height direction Z of the cabinet 110, so that the second air outlet 132e can cover more area in the height direction Z of the first refrigeration chamber 112a, thereby allowing cold air to blow to different heights, so that cold air can reach different heights as much as possible, thereby improving the cooling effect.

[0092] In other words, the first air outlet 132d and the second air outlet 132e can work together to make the first refrigeration chamber 112a cool as evenly as possible.

[0093] In some embodiments, the second air outlet 132e is located near the rear wall of the refrigerator compartment 112. The rear wall refers to the wall opposite to the door 120. By locating the air outlet near the rear wall of the refrigerator compartment 112 (near the rear wall of the first refrigerator cavity 112a), the loss of cold air during the opening of the door 120 can be reduced, and the possibility of cold air blowing directly on the user can also be reduced, thereby improving the user experience.

[0094] Figure 9 It shows Figure 4 A magnified view of a section at point I, as shown below. Figure 9 As shown, regarding the air outlet configuration of the first fan 136, the first fan 136 can be positioned above the first evaporator 134. The first fan 136 may include a first volute 136a and a first impeller 136b. The first impeller 136b is installed inside the first volute 136a. A first air inlet 136c, a first refrigerated air outlet 136d, and a second refrigerated air outlet 136e may be provided on the first volute 136a. The first refrigerated air outlet 136d is connected to the first air outlet 132d, the second refrigerated air outlet 136e is connected to the second air outlet 132e, and the first air inlet 136c is connected to the refrigerated return air outlet 132c.

[0095] The above describes the location and configuration of the refrigeration air outlet 132b and refrigeration air return vent 132c in the first refrigeration chamber 112a. The location and configuration of the refrigeration air outlet 132b and refrigeration air return vent 132c in the second refrigeration chamber 112b are the same as those in the first refrigeration chamber 112a. The location of the refrigeration air outlet 132b and refrigeration air return vent 132c in the second refrigeration chamber 112b can be referenced from the location and configuration of the refrigeration air outlet 132b and refrigeration air return vent 132c in the first refrigeration chamber 112a, and will not be described again here.

[0096] In some embodiments, the first housing 132 is foam-bonded to the cabinet 110. During installation, the first fan 136 and the first evaporator 134 can be pre-installed inside the first housing 132, and then the first housing 132 can be pre-installed inside the refrigerator liner 117. Finally, foaming liquid is filled between the outer shell 116 and the refrigerator liner 117, so that the first housing 132 and the refrigerator liner 117 are foam-bonded.

[0097] Specifically, a groove 117a can be provided on the inner refrigeration liner 117, and a protrusion 137 can be provided on the first shell 132. During pre-installation, since the inner refrigeration liner 117 has a certain degree of plasticity, the first shell 132 can be pushed into the inner refrigeration liner 117, so that the protrusion 137 is inserted into the groove 117a, and the pre-installation of the first shell 132 and the inner refrigeration liner 117 is completed.
