Description

Air Conditioner Controller Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioning controller. Background Technology

[0002] With the continuous development of air conditioning technology, air conditioners have become increasingly important in people's lives. Especially with the use of central air conditioning systems, the controllers, which operate under high voltage, pose a risk of short circuits and fires when the electronic components on the printed circuit board reach high temperatures and the voltage is high. Because the internal wiring is extensive and the controllers are often made of plastic, fire can easily spread from the printed circuit board to the control panel, causing a fire. This potential hazard is prevalent in current controllers. Summary of the Invention

[0003] The purpose of this disclosure is to provide an air conditioner controller that solves the fire hazard problem of existing air conditioner controllers.

[0004] To achieve the above objectives, this disclosure provides an air conditioner controller, including: a printed circuit board, a control panel, and a fireproof plate, wherein the printed circuit board is electrically connected to the control panel, and the fireproof plate is located between the printed circuit board and the control panel.

[0005] As an optional implementation, the fireproof board is a galvanized metal sheet.

[0006] As an optional implementation, the galvanized sheet is a galvanized sheet that has undergone electrophoretic treatment.

[0007] As an optional implementation, the vertical projection of the fireproof plate onto the plane of the printed circuit board coincides with the printed circuit board.

[0008] As an optional implementation, the printed circuit board is electrically connected to the control panel via a connecting wire, and the fireproof board has a through hole through which the connecting wire passes.

[0009] As an optional implementation, the number of fireproof boards is at least two.

[0010] As an optional implementation, at least two of the fireproof boards include a first fireproof board and a second fireproof board, wherein the first fireproof board has a first through hole and the second fireproof board has a second through hole, and the connecting wire is sequentially passed through the first through hole and the second through hole.

[0021] Figure 3 is a schematic diagram of the printed circuit board and the first grille plate of the air conditioner controller provided in this disclosure. Detailed Implementation

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] Referring to Figure 1, which is an exploded view of an air conditioner controller provided in an embodiment of this disclosure, the air conditioner controller provided in this disclosure includes: a printed circuit board 10, a control panel 20, and a fireproof plate 30. The printed circuit board 10 is electrically connected to the control panel 20, and the fireproof plate 30 is located between the printed circuit board 10 and the control panel 20.

[0024] The working principle of this embodiment can be found in the following description:

[0025] The air conditioner controller in this embodiment includes a printed circuit board 10, a control panel 20, and a fireproof plate 30. The fireproof plate 30 is located between the printed circuit board 10 and the control panel 20. In this way, when a short circuit occurs in the electronic components on the printed circuit board 10, causing a fire, the fireproof plate 30 can act as a barrier between the printed circuit board 10 and the control panel 20, reducing the speed at which the fire on the printed circuit board 10 spreads to the control panel 20. That is, the fireproof plate 30 can enhance the fire resistance of the air conditioner controller.

[0026] It should be noted that the air conditioner controller of this embodiment has a low cost and good fire resistance. In addition, it does not make the air conditioner controller too large, thus enhancing the overall aesthetics of the air conditioner controller.

[0027] The air conditioner controller can be used to control the air conditioner to operate in the following modes, and the above operating modes can include at least some of the following modes: cooling mode, heating mode, silent mode, etc.

[0028] Alternatively, the air conditioner controller can be mounted on a wall to enhance its fixation and installation effect. For example, a mounting groove can be provided on the wall, and the air conditioner controller can be partially embedded in the mounting groove to further enhance its fixation effect. The control panel 20 of the air conditioner controller can be exposed outside the mounting groove, so that users can operate it on the control panel 20 to control the air conditioner.

[0029] The materials used to make the control panel 20 are not limited here. Optionally, the control panel 20 can be made of materials such as plastic.

[0030] The printed circuit board 10 can be referred to as the main circuit board or the control circuit board. At least some of the electronic components on the printed circuit board 10 are usually under high voltage, which makes them prone to short circuits and fires.

[0031] Optionally, referring to Figures 1 and 2, the air conditioning controller may also include a printed circuit board cover 40, which can be used to accommodate the printed circuit board 10 and enhance the accommodating effect of the printed circuit board 10.

[0032] Optionally, referring to Figure 1, the air conditioner controller may further include a mounting box 50. The mounting box 50 can be embedded in a recess in the mounting wall and can be fixedly connected to the control panel 20. The fireproof plate 30, printed circuit board 10, and printed circuit board cover 40 can all be disposed in the mounting box 50. In this way, the mounting box 50 can enhance the housing effect of the fireproof plate 30, printed circuit board 10, and printed circuit board cover 40, and separate the fireproof plate 30, printed circuit board 10, and printed circuit board cover 40 from the wall, thereby enhancing the dustproof and waterproof effects of the fireproof plate 30, printed circuit board 10, and printed circuit board cover 40.

[0033] Optionally, referring to Figures 1 and 2, the air conditioner controller may also include a middle shell 60, and the control panel 20 may be fixedly connected to the mounting box 50 through the middle shell 60. In this way, by setting the middle shell 60, the stability of the connection between the control panel 20 and the mounting box 50 can be enhanced. It should be noted that both the middle shell 60 and the control panel 20 may be located outside the mounting recess, that is, both the middle shell 60 and the control panel 20 may be located outside the wall.

[0034] It should be noted that the specific material of the fireproof board 30 is not limited here. Optionally, the fireproof board 30 can be a metal plate.

[0035] As another optional implementation, the fireproof board 30 is made of galvanized metal sheet. This provides better rust prevention, extending the service life of the fireproof board 30 and thus ensuring its fire-resistant performance. Simultaneously, the fireproof board 30 can prevent flames or open flames on the printed circuit board 10 from spreading to the control panel 20, thereby enhancing its fire resistance.

[0036] As an optional implementation, the galvanized steel sheet is an electrophoretic-treated galvanized steel sheet. Because of the high temperature and humidity within the wall groove, the galvanized steel sheet treated with electrophoresis exhibits better rust prevention. When the humidity is high, the electrophoretic-treated galvanized steel sheet can further enhance its rust-preventive effect, thereby extending its service life.

[0037] As an optional implementation, the vertical projection of the fireproof plate 30 onto the plane of the printed circuit board 10 coincides with the printed circuit board 10.

[0038] In this embodiment, since the vertical projection of the fireproof plate 30 on the plane of the printed circuit board 10 coincides with the printed circuit board 10, the fireproof plate 30 can completely cover the printed circuit board 10, thereby enhancing the fire-blocking effect on the printed circuit board 10, that is, further improving the fireproof performance of the fireproof plate 30.

[0039] As an optional implementation, referring to Figure 2, the printed circuit board 10 and the control panel 20 are electrically connected via a connecting line 70. The fireproof plate 30 has a through hole, and the connecting line 70 passes through the through hole.

[0040] The shape of the through hole is not limited here. Optionally, the through hole can be a rectangular through hole, a circular through hole, an elliptical through hole, etc.

[0041] It should be noted that the shape of the through hole can match the shape of the cross-section of the connecting line 70, which can enhance the limiting effect of the through hole on the connecting line 70.

[0042] In this embodiment of the disclosure, the fireproof board 30 has a through hole, and the connecting wire 70 passes through the through hole. In this way, the through hole can limit the connection wire 70.

[0043] It should be noted that the number of fireproof boards 30 is not limited here; optionally, the number of fireproof boards 30 can be one.

[0044] As another optional implementation, the number of fireproof panels 30 is at least two. Thus, by providing at least two fireproof panels 30, the fire resistance of the air conditioning controller is further enhanced.

[0045] It should be noted that at least two fireproof boards 30 can be stacked sequentially, or at least two fireproof boards 30 can be spaced out sequentially. The specific installation method is not limited here.

[0046] As an optional implementation, referring to Figures 1 and 2, at least two of the fireproof boards 30 include a first fireproof board 31 and a second fireproof board 32. The first fireproof board 31 has a first through hole 311, and the second fireproof board 32 has a second through hole 321. The connecting wire 70 passes through the first through hole 311 and the second through hole 321 in sequence.

[0047] The first through hole 311 and the second through hole 321 can have the same or different shapes. For example, the first through hole 311 and the second through hole 321 can both be circular through holes; or one of the first through hole 311 and the second through hole 321 can be a circular through hole and the other can be an elliptical through hole.

[0048] In this embodiment, the connecting wire 70 is sequentially passed through the first through hole 311 and the second through hole 321, which can further enhance the limiting effect on the connecting wire 70.

[0049] As an optional implementation, referring to Figure 2, the connecting line 70 is arranged in an S-shape.

[0050] In this embodiment, since the connecting line 70 connects the printed circuit board 10 and the control panel 20 respectively, when a short circuit occurs in the electronic components on the printed circuit board 10, causing a fire, the fire can spread along the connecting line 70 to the control panel 20. The connecting line 70 is S-shaped, which can prolong the spread path of the fire along the connecting line 70 to the control panel 20, thereby prolonging the time it takes for the control panel 20 to catch fire and providing sufficient time for firefighting.

[0051] As an optional implementation, referring to Figure 1, the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located is offset from the second through hole 321.

[0052] In this embodiment, since the connecting wire 70 is sequentially passed through the first through hole 311 and the second through hole 321, and the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located is offset from the second through hole 321, the distance between the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located and the second through hole 321 is longer. Thus, a longer connecting wire 70 can be selected, thereby achieving the purpose of extending the fire duration of the control panel 20.

[0053] As an optional implementation, referring to FIG1, the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located is close to the first edge 3201 of the second fireproof board 32, and the second through hole 321 is close to the second edge 3202 of the second fireproof board 32. The first edge 3201 and the second edge 3202 are arranged opposite to each other.

[0054] Wherein, the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located is close to the first edge 3201 of the second fireproof board 32, and the second through hole 321 is close to the second edge 3202 of the second fireproof board 32. It can be understood that: the distance between the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located and the first edge 3201 is the first distance, and the distance between the second through hole 321 and the second edge 3202 is the second distance. The first distance and the second distance can both be greater than 0, and the first distance and the second distance can both be less than the preset distance.

[0055] In addition, the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located is close to the first edge 3201 of the second fireproof board 32, and the second through hole 321 is close to the second edge 3202 of the second fireproof board 32. It can also be understood that the vertical projection of the first through hole 311 on the plane where the second fireproof board 32 is located is adjacent to the first edge 3201, and the second through hole 321 is adjacent to the second edge 3202.

[0056] In this embodiment, the vertical projection of the first through hole 311 on the plane of the second fireproof plate 32 is close to the first edge 3201 of the second fireproof plate 32, and the second through hole 321 is close to the second edge 3202 of the second fireproof plate 32. This makes the distance between the vertical projection of the first through hole 311 on the plane of the second fireproof plate 32 and the second through hole 321 as long as possible, thereby extending the duration of the fire in the control panel 20 as much as possible.

[0057] As an optional implementation, referring to FIG3, a first grid plate 80 is provided on the first surface of the printed circuit board 10, and the connecting line 70 partially abuts against the first grid plate 80. The first grid plate 80 is made of flame-retardant material, and the first surface is the surface facing the control panel 20.

[0058] The first grid plate 80 can be understood as a plate with multiple grids. The grids can be understood as openwork meshes, so the grids can also be called meshes, and the first grid plate 80 can also be called the first mesh plate.

[0059] In this embodiment of the present disclosure, a first grid plate 80 is provided on the first surface of the printed circuit board 10. The first grid plate 80 is made of a flame-retardant material, which makes the first grid plate 80 difficult to burn, thereby further enhancing the fire resistance of the air conditioner controller.

[0060] It should be noted that the specific materials used for flame-retardant materials are not limited here. Optionally, flame-retardant materials can be flame-retardant plastics, which can be a mixture of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS).

[0061] As an optional implementation, the length of the first grid plate 80 along the first direction is greater than or equal to the length of the solder pads on the printed circuit board 10 along the first direction, where the first direction is the direction in which the printed circuit board 10 points to the control panel 20.

[0062] As shown in Figure 1, the first direction can be understood as direction A in Figure 1.

[0063] In this embodiment of the present disclosure, the connecting line 70 abuts against the first grid plate 80, and the length of the first grid plate 80 along the first direction is greater than or equal to the length of the solder pads on the printed circuit board 10 along the first direction. In this way, the solder pads on the printed circuit board 10 can be prevented from contacting the connecting line 70, thereby preventing the connecting line 70 from being cut, thus enhancing the protection performance of the connecting line 70.

[0064] As an optional implementation, a second grid plate is provided on the second surface of the printed circuit board 10, the second surface being disposed opposite to the first surface, and the second grid plate being made of a flame-retardant material.

[0065] In this embodiment of the disclosure, the structure of the second grille can be referred to the relevant description of the first grille 80, and has the same beneficial technical effect, that is, the second grille is provided on the second surface of the printed circuit board 10, and the second grille is made of flame-retardant material, so that the second grille is difficult to be burned, thereby further enhancing the fire resistance of the air conditioner controller.

[0066] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
