Description

Technical Field

[0001] This application belongs to the field of refrigerator technology, and particularly relates to an electronic control box for a refrigerator and a refrigerator. Background Technology

[0002] A variable frequency refrigerator is a type of refrigerator that uses variable frequency technology to achieve more precise temperature control and greater energy efficiency by adjusting the operating frequency of the compressor. The control box of a variable frequency refrigerator contains a variable frequency circuit board. Because the variable frequency circuit board is prone to generating high-frequency switching noise and voltage surges during operation, an inductor is usually added to the control box to filter out high-frequency noise, protect the circuit, and stabilize the voltage.

[0003] An existing type of electrical control box has a recessed mounting cavity in its inner wall to form a space for mounting the inductor. However, because the control coil in the electrical control box vibrates when it is working, causing the box body to vibrate, the presence of the mounting cavity constitutes an acoustic cavity, which will generate significant electromagnetic noise and lead to a poor user experience.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0037] This application provides an embodiment of a refrigerator's electronic control box; for example, please refer to [link to example]. Figures 1-2 , Figure 1 This is a schematic diagram of the structure of the electrical control box provided in the embodiments of this application. Figure 2 for Figure 1 The exploded view of the control box shown. The refrigerator's control box 100 includes a box body 110 and a fixing component 120.

[0038] The box 110 has an internal accommodating space 111, and an installation cavity 112 is recessed on the inner wall of the box 110 facing the accommodating space. The installation cavity 112 is used to install the refrigerator's inductor. One end of the fastener 120 is fixedly connected to the installation cavity 112, and the other end is used to be fixedly connected to the refrigerator's cabinet.

[0039] It should be noted that the electrical control box 100 is an important component inside the refrigerator, responsible for controlling and managing the refrigerator's electrical system. The accommodating space 111 is used to house components such as the refrigerator's control panel.

[0040] The electrical control box 100 provided in this application embodiment fixes the mounting cavity 112 to the refrigerator body by adding a fixing member 120, which reduces the degree of freedom of movement of the mounting cavity 112 and increases the natural frequency of the mounting cavity 112, thereby reducing the vibration of the mounting cavity 112 and reducing the electromagnetic noise generated by the electrical control box 100.

[0041] Optionally, the mounting cavity 112 has a through hole 113, and the fastener 120 includes a screw that passes through the through hole 113 and is used to screw onto the refrigerator body, so that the mounting cavity 112 is fixedly connected to the refrigerator body. Preferably, the through hole 113 is a threaded hole, and the screw is also screwed into the threaded hole.

[0042] In some embodiments, to prevent noise from propagating to the outside through the gap between the through hole 113 and the fixing member 120, a sealing member (not shown) may be added. The sealing member is disposed between the through hole and the screw. The sealing member is sealed to the through hole 113 and the fixing member 120 to block the gap between the through hole 113 and the fixing member 120, thereby reducing noise propagating to the outside of the electrical control box. On the other hand, it can also prevent external dust, moisture and other substances from entering the mounting cavity 112 and the receiving space 111 through the through hole 113, thereby avoiding contamination of the internal components of the electrical control box and affecting the service life of the components. The sealing member can be a sealant, a rubber ring, a silicone ring or other sealing structure.

[0043] In some embodiments, please refer to Figures 3-4 , Figure 3 This is another structural schematic diagram of the electrical control box provided in an embodiment of this application. Figure 4 for Figure 3 The exploded view of the electrical control box is shown. A mass block 130 is also provided on the inner wall of the mounting cavity 112. The mass block 130 is fixedly connected to the inner wall of the mounting cavity 112, which can increase the natural frequency of the mounting cavity 112 and reduce the cavity volume inside the mounting cavity 112, thereby further reducing the vibration of the mounting cavity 112 and reducing the electromagnetic noise emitted by the electrical control box 100.

[0044] Optionally, the mass block 130 is composed of one or more composite materials selected from putty, metal, stone, and rubber. For example, the mass block 130 is made of putty and is fixed to the inner wall of the mounting cavity 112 by adhesive.

[0045] In some embodiments, sound-absorbing cotton (not shown in the figure) is provided on the inner wall of the mounting cavity 112. In this way, some high-frequency noise can be absorbed by the sound-absorbing cotton. It should be noted that the inner wall of the mounting cavity 112 can be provided with both a mass block 130 to eliminate low-frequency noise and sound-absorbing cotton to eliminate high-frequency noise.

[0046] Optionally, the box body 110 includes a box body 114 and a cover 115. The box body 114 forms an accommodating space 111 with an opening 116. The cover 115 is detachably fitted onto the box body 114 to close the opening 116. A mounting cavity 112 is recessed on the inner wall of the cover 115 facing the accommodating space 111. Preferably, the mounting cavity 112 includes a mounting wall 1121 facing the accommodating space 111. The mounting wall 1121 includes a central region and an edge region surrounding the central region. One end of the fastener 120 is fixedly connected to the central region. For example, a through hole 113 is formed on the mounting wall 1121, and is located at the center of the mounting wall 1121. In this way, the vibration damping area of ​​the mounting cavity 112 can be maximized, improving the noise reduction effect.

[0047] In some embodiments, an insulating cover (not shown) may be provided within the receiving space 111 to cover the control coil. This further isolates the vibration noise of the refrigerator's control coil, thereby reducing the noise transmitted from the control box 100.

[0048] The electrical control box 100 provided in this application embodiment fixes the mounting cavity 112 to the refrigerator body by adding a fixing member 120, which reduces the degree of freedom of movement of the mounting cavity 112 and increases the natural frequency of the mounting cavity 112, thereby reducing the vibration of the mounting cavity 112 and reducing the electromagnetic noise generated by the electrical control box 100.

[0049] This application also provides a refrigerator, for example, please refer to [link to example]. Figure 5 , Figure 5 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. The refrigerator 10 can be as follows: Figure 5 The French-style refrigerator shown can also be a side-by-side refrigerator, a cross-door refrigerator, or other types of refrigerators. Refrigerator 10 includes the electrical control box 100 and the cabinet 200 in any of the above embodiments, and the mounting cavity 112 is fixedly connected to the cabinet 200 by a fastener 120.

[0050] The refrigerator 10 provided in this application embodiment fixes the mounting cavity 112 to the cabinet 200 by adding a fixing member 120, which reduces the degree of freedom of movement of the mounting cavity 112 and increases the natural frequency of the mounting cavity 112, thereby reducing the vibration of the mounting cavity 112 and reducing the electromagnetic noise generated by the electronic control box 100.

[0051] The above provides a detailed description of the refrigerator's electrical control box and the refrigerator provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
