Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a refrigeration component and a refrigerator. Background Technology

[0002] Because the refrigeration duct is made of ABS (ABS is an abbreviation for Acrylonitrile Butadiene Styrene, referring to acrylonitrile-butadiene-styrene copolymer) plastic, the heaters and finned evaporators in existing refrigerators are all located in the refrigeration duct. The refrigeration duct is easily deformed by the operation of the heater, causing gaps to appear between the refrigeration duct and the freezer compartment. When the refrigerator compressor starts and the refrigeration fan is running, some air that has not been fully heated by the finned evaporator is blown into the freezer or refrigerator compartment, resulting in a slow cooling speed in the freezer or refrigerator compartment, thus reducing the refrigerator's cooling efficiency.

[0003] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a refrigeration component and a refrigerator, which aims to solve the problem that the refrigeration air duct inside the refrigerator is easily affected by the operation of the heater, resulting in deformation of the refrigeration air duct, causing the finned evaporator and the refrigeration air duct to be poorly sealed, thereby resulting in poor refrigeration efficiency of the refrigerator.

[0018] As a further improved technical solution, the channel inside the housing is connected to the refrigeration air duct, and the opposite sides of the housing abut against the two sides of the refrigeration air duct respectively.

[0019] As a further improved technical solution, a refrigeration air duct is provided on the side near the refrigeration door, and the refrigeration air duct is connected to the refrigeration chamber through the cold air duct.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In existing technology, the heater and evaporator in a refrigerator are generally assembled separately and scattered in the freezer air duct. Therefore, the assembly is time-consuming and takes up a lot of space. At the same time, since the freezer air duct is made of ABS plastic, it is easily deformed by the operation of the heater, which causes the finned evaporator to be tightly sealed to the freezer air duct. When the refrigerator compressor starts and the freezer fan is running, some of the air that has not been fully heated by the finned evaporator is blown into the freezer or refrigerator compartment, resulting in a slow cooling speed in the freezer or refrigerator compartment, thus reducing the refrigerator's cooling efficiency.

[0033] Therefore, the present invention provides the following embodiments to solve the above-mentioned problems.

[0034] Example 1:

[0035] Please see Figures 1-3 The refrigeration assembly includes a housing 1 with a channel inside; an evaporator 2 disposed inside the housing 1; and a heater 3 disposed inside the housing 1.

[0036] like Figures 1-3As shown, in this embodiment, the refrigeration assembly includes a housing 1, an evaporator 2, and a heater 3. The housing 1 is a cuboid with openings at opposite ends and a channel formed inside. The evaporator 2 is disposed inside the housing 1, with one end of the evaporator 2 located outside the housing 1 as the inlet and outlet of the refrigerant. The heater 3 is disposed inside the housing 1. The housing 1 is a rigid housing. By placing the heater 3 and the evaporator 2 together in the housing 1, the space occupied by the heater 3 and the evaporator 2 inside the refrigerator can be reduced. The refrigeration component provided in this embodiment is used in a refrigerator. After the refrigeration component is installed in the refrigerator, it is only necessary to fix the housing 1 inside the refrigerator to complete the fixation of the heater 3 and the evaporator 2, saving the time of installing the heater 3 and the evaporator 2 in stages. Compared with the scattered distribution of the heater 3 and the evaporator 2 in the prior art, the refrigeration component in this embodiment concentrates the heater 3 and the evaporator 2 inside the housing 1, which can further save the space occupied by the heater 3 and the evaporator 2 during installation. At the same time, by placing the heater 3 inside the housing 1, the refrigeration component provided in this embodiment can reduce the impact of the heater 3 on the freezing air duct 10 after the refrigeration component is installed in the freezing air duct 10 of the refrigerator, thereby slowing down the deformation of the freezing air duct 10. Furthermore, by using the housing 1 to cover the evaporator 2, the housing 1 can resist the deformation of the freezing air duct 10 and play a certain supporting role. Moreover, the channel inside the housing 1 can also form an air duct that communicates with the freezing air duct 10, thereby ensuring that the air in the freezer compartment 8 that has not been heat-exchanged by the evaporator 2 can enter the housing 1 to complete the heat exchange with the evaporator 2, thereby ensuring and improving the refrigeration efficiency of the refrigerator.

[0037] As a further embodiment, the refrigeration assembly also includes a defrost sensor 4, which is disposed on the evaporator 2. Specifically, the defrost sensor 4 is disposed on the end of the evaporator 2 exposed outside the casing 1. The defrost sensor 4 is used to sense the room temperature inside the refrigerator. For example, when the temperature inside the refrigerator is too low, which will cause frost to form inside the refrigerator, the defrost sensor 4 feeds back the sensed temperature to the refrigerator's control panel. After receiving this information, the refrigerator's control panel controls the heater 3 to turn on, adjusting the room temperature inside the refrigerator to prevent frost formation.

[0038] As a further improvement, the refrigeration assembly also includes a fixing plate 5, which is disposed within the housing 1. The evaporator 2 and the heater 3 are both mounted on the fixing plate 5. Specifically, the fixing plate 5 is a metal sheet. The evaporator 2 is mounted on the fixing plate 5, for example, with its pipes passing through it. The evaporator 2 and the fixing plate 5 form a finned evaporator 2. The side of the fixing plate 5 is welded to the inner side of the housing 1. One end of the fixing plate 5 also has a snap-fit ​​(not shown), through which the heater 3 is engaged with the fixing plate 5. The fixing plate 5 enhances the stability and integrity of the evaporator 2 and the heater 3 within the housing 1. Furthermore, the refrigeration assembly in this embodiment can be manufactured and assembled in the factory, facilitating handling and transportation.

[0039] In this embodiment, multiple fixing plates 5 are provided, and the multiple fixing plates 5 are evenly distributed within the housing 1. Specifically, there are three fixing plates 5, which are identical in size and shape and are arranged side by side within the housing 1, with the spacing between adjacent fixing plates 5 being consistent.

[0040] As a further embodiment, the housing 1 includes a metal housing 1. For example, the housing 1 includes an aluminum housing because aluminum is lighter, easier to process, more widely available, and chemically more stable. It does not rust as easily as iron products, and aluminum has good thermal conductivity, second only to expensive metals such as silver and copper, while also being cheaper and more cost-effective.

[0041] As a further improvement, the outer side of the housing 1 is provided with a connecting part 6, and the connecting part 6 is provided with a through hole 7. Specifically, the connecting part 6 is located on the side of the housing 1 near the defrost sensor 4, the connecting part 6 is an L-shaped bent surface, and one side of the connecting part 6 is provided with a through hole 7. The connecting part 6 can be fixed inside the refrigerator by a pin or screw passing through the through hole 7.

[0042] Example 2:

[0043] This embodiment provides a refrigerator; please refer to [link / reference]. Figures 4-6The refrigerator includes a freezer compartment 8, a freezer door 9, a freezer air duct 10, and a refrigeration assembly. The freezer door 9 is located on one side of the freezer compartment 8, the freezer air duct 10 is located on the side of the freezer compartment 8 away from the freezer door 9, and the refrigeration assembly is located within the freezer air duct 10. Specifically, the refrigerator also includes a compressor assembly 12. When the compressor assembly 12 and the refrigeration fan (not shown) are turned on, air in the freezer compartment 8 enters the freezer air duct 10 from bottom to top, passes through the refrigeration assembly, and forms cold air after heat exchange with the evaporator 2. By using the refrigeration assembly, the freezer air duct 10 can be prevented from expanding and sealing due to the influence of the heater 3, thus improving the refrigeration efficiency of the refrigerator.

[0044] As a further embodiment, the channel within the housing 1 communicates with the refrigeration air duct 10, and the opposite sides of the housing 1 abut against the sides of the refrigeration air duct 10. When the heater 3 is operating, the sidewalls of the refrigeration air duct 10 will expand due to the high temperature. However, since the sidewalls of the refrigeration air duct 10 abut against the housing 1 and are supported by the housing 1, they are unlikely to expand or will only expand slightly, thus not interfering with the heat exchange of the evaporator 2 with the air. Therefore, installing the refrigeration components inside the refrigerator's refrigeration air duct 10 can improve the refrigerator's refrigeration efficiency.

[0045] As a further improvement, a refrigeration damper 11 is provided on the side of the refrigeration duct 10 near the refrigeration door 9, and the refrigeration duct 10 is connected to the freezer compartment 8 through the refrigeration damper. Specifically, the refrigeration damper 11 is located between the refrigeration duct 10 and a drawer (not shown) inside the freezer compartment 8, and the cold air after heat exchange with the evaporator 2 can directly enter the freezer compartment 8 for cooling through the refrigeration damper 11.

[0046] In this embodiment, the refrigerator also includes a control module (not shown), and the heater 3 and the defrost sensor 4 are electrically connected to the control module. When the defrost sensor 4 senses that the temperature of the cold air inside the freezer duct 10 is too low and will cause frost to form in the refrigerator, the defrost sensor 4 transmits this information to the control module. The control module then turns on the heater 3 to raise the temperature of the air inside the refrigerator to prevent frost from forming. When the temperature reaches the upper limit, the defrost sensor 4 transmits this information to the control module again, and the control module controls the heater 3 to turn off. The refrigerator also includes screws (not shown), which pass through the through hole 7 and are located on the side wall of the freezer duct 10. The refrigeration components are detachably connected to the side wall of the freezer duct 10 via the screws.

[0047] In summary, this invention provides a refrigeration assembly for a refrigerator, comprising: a housing 1 with a channel inside; an evaporator 2 disposed within the housing 1; and a heater 3 disposed within the housing 1. By placing the heater 3 within the housing 1, the refrigeration assembly provided by this invention reduces the impact of the heater 3 on the freezing air duct 10 when the refrigeration assembly is installed within the refrigerator's freezing air duct 10, thereby mitigating deformation of the freezing air duct 10. Furthermore, by covering the evaporator 2 with the housing 1, the housing 1 can resist deformation of the freezing air duct 10, providing a certain degree of support. The channel within the housing 1 also forms an air duct connected to the freezing air duct 10, ensuring that air in the freezer compartment 8 that has not undergone heat exchange with the evaporator 2 can enter the housing 1 and complete heat exchange with the evaporator 2, thus ensuring and improving the refrigerator's refrigeration efficiency.
