Description

Technical Field

[0001] This utility model relates to a Hall sensor mounting structure for air conditioners, belonging to the field of air conditioner technology. Background Technology

[0002] With the continuous development and improvement of air conditioning technology, air conditioners no longer simply offer cooling and heating functions. Many air conditioners now feature air purification functions such as formaldehyde removal, disinfection, and PM2.5 removal. Because individual needs vary, these functions are often set as optional extras, and various functions can be achieved by replacing the air filter module. Since replacing each module will change the air conditioner's parameters, Hall effect sensors are used to detect the replaced air filter module and adapt to the corresponding air conditioner parameters. The traditional installation method for Hall effect sensors involves using two screws or a locating pin and a screw for installation and fixation, which is relatively inefficient. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a Hall sensor mounting structure for air conditioners, including an air conditioner housing and a Hall sensor. The air conditioner housing is provided with an air inlet, and a filter module mounting groove for mounting an air conditioner filter module is provided at the outer end face of the air inlet. A boss is provided in the area where the air inlet is located in the inner cavity of the air conditioner housing. The filter module mounting groove is located in the area where the boss is located. A first positioning mounting plane is provided on the outer surface of the boss at the position corresponding to the side wall of the filter module mounting groove. A first slot is provided at one end of the first positioning mounting plane, and a first groove is provided at the other end. There is a second slot. Both the first and second slots are connected to the inner cavity of the filter module mounting groove. The Hall sensor housing is provided with a first fastener and a second fastener. The Hall sensor housing is provided with a second positioning mounting plane. The Hall sensor is fixedly installed on the first positioning mounting plane by the fastening connection between the first fastener and the first slot and the fastening connection between the second fastener and the second slot. At this time, the second positioning mounting plane and the first positioning mounting plane are in contact. The undercut parts of the first fastener and the undercut parts of the second fastener abut against the inner cavity sidewall of the filter module mounting groove.

[0005] A further preferred embodiment is that the air inlet cross-section is rectangular, the width direction of the air inlet cross-section is set as the first direction, the axial direction is set as the second direction, the first positioning mounting plane extends along the first direction, and the Hall sensor is simultaneously limited in both directions in the first direction and in the second direction through the contact and cooperation between the first fastener and the side wall of the first slot, and the contact and cooperation between the second fastener and the side wall of the first slot.

[0006] A further preferred embodiment is that the buckle portion of the first fastener is protruding towards the direction of the second fastener relative to the connecting portion of the first fastener, and the buckle portion of the second fastener is protruding towards the direction of the connecting portion of the second fastener relative to the direction of the first fastener.

[0007] A further preferred embodiment is that two first or second fasteners are arranged at intervals along the second direction.

[0008] A further preferred embodiment is that the inner wall of the air conditioner housing has a third positioning mounting surface on the side where its air inlet is located, and the outer shell of the Hall sensor has a fourth positioning mounting surface that fits into the third positioning mounting surface.

The side wall structure integrates a first slot and a second slot. The Hall sensor is fixedly installed by the first fastener connecting to the first slot and the second fastener connecting to the second slot. After fixed installation, the second positioning mounting plane and the first positioning mounting plane fit together.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 12As shown, this utility model includes an air conditioner housing 10 and a Hall sensor 20. The air conditioner housing 10 is provided with an air inlet 11, and a filter module mounting groove 12 for mounting an air conditioner filter module is provided on the outer end face of the air inlet 11. A boss 13 is provided in the area where the air inlet 11 is located in the inner cavity of the air conditioner housing 10. The filter module mounting groove 12 is located in the area where the boss 13 is located. A first positioning mounting plane 14 is provided on the outer surface of the boss 13 at a position corresponding to the side wall of the filter module mounting groove 12. A first slot 15 is provided at one end of the first positioning mounting plane 14, and a second slot 16 is provided at the other end (the first slot 15 and the second slot 16 only need to be at least partially located on the first positioning mounting plane 14. For example, in the embodiment shown in the figure, the first slot 15 can partially extend to the rounded corner of the outer surface of the boss 13). The first slot 15 and the second slot 16 are both connected to the inner cavity of the filter module mounting groove 12 (that is, the side wall structure formed between the outer surface of the boss and the inner wall of the filter module mounting groove serves as the main body for arranging the first slot 15 and the second slot 16). The outer shell of the Hall sensor 20 is provided with a first fastener 21 and a second fastener 22, and the outer shell of the Hall sensor 20 is provided with a second positioning mounting plane 23. The Hall sensor 20 is fixedly installed on the first positioning mounting plane 14 through the fastening connection between the first fastener 21 and the first slot 15, and the fastening connection between the second fastener 22 and the second slot 16. At this time, the second positioning mounting plane 23 and the first positioning mounting plane 14 are in contact, and the undercut portions of the first fastener 21 and the second fastener 22 abut against the inner cavity side wall of the filter module mounting groove 12. The air conditioner housing 10 in this utility model refers to the housing component used to install the air conditioner filter module, which can usually be the air conditioner frame. The outer end face of the air inlet 11 refers to the side of the air inlet 11 that is close to the external space of the air conditioner. This invention forms the main structure for arranging the filter module mounting groove 12 by providing a boss 13 on the inner wall of the air conditioner housing 10. The side wall structure formed between the outer surface of the boss 13 and the inner wall of the filter module mounting groove 12 serves as the mounting base for the Hall sensor 20. This side wall structure integrates a first slot 15 and a second slot 16. The Hall sensor 20 is fixedly installed by the first fastener 21 connecting to the first slot 15 and the second fastener 22 connecting to the second slot 16. After fixed installation, the second positioning mounting plane 23 and the first positioning mounting plane 14 fit together. The undercut portions of the first fastener 21 and the second fastener 22 abut against the inner side wall of the filter module mounting groove 12, ensuring the overall structural reliability. This invention eliminates the need for screws, effectively improving assembly efficiency.

[0027] For ease of installation, the main body of the air conditioning filter module is typically rectangular (excluding necessary connecting and positioning components). Correspondingly, the air inlet 11 has a rectangular air intake cross-section (excluding necessary connecting and positioning components). The width direction of the air intake cross-section of the air inlet 11 is set as the first direction, and the axial direction is set as the second direction. The first positioning mounting plane 14 extends along the first direction. The contact and cooperation between the first fastener 21 and the side wall of the first slot 15, and the contact and cooperation between the second fastener 22 and the side wall of the first slot 15, simultaneously achieve bidirectional limiting of the Hall sensor 20 in the first direction and bidirectional limiting in the second direction. Correspondingly, the length direction of the air intake cross-section of the air inlet 11 can be set as the third direction. The aforementioned "the second positioning mounting plane 23 and the first positioning mounting plane 14 are in contact, and the undercut portions of the first fastener 21 and the second fastener 22 abut against the inner cavity side wall of the filter module mounting groove 12" ensures that the Hall sensor 20 is bidirectionally limited in the third direction. Therefore, through the above structural design, the Hall sensor 20 can be reliably limited in six directions—front, back, left, right, up, and down—ensuring the overall structural reliability. To further improve the overall structural reliability, a third positioning mounting plane 17 and a fourth positioning mounting plane 27 can be added. Specifically, the inner wall of the air conditioner housing 10 has a third positioning mounting plane 17 on the side where its air inlet 11 is located, and the outer shell of the Hall sensor 20 has a fourth positioning mounting plane 27 that fits against the third positioning mounting plane 17. To further improve the overall structural reliability, the positional relationship between the third positioning mounting plane 17 and the first positioning mounting plane 14 is preferably designed so that they are perpendicular to each other.

[0028] To further improve the overall structural reliability, the undercut portion of the first fastener 21 protrudes towards the second fastener 22 relative to its connecting portion, and the undercut portion of the second fastener 22 protrudes towards the first fastener 21 relative to its connecting portion. It can be understood that the connecting portion of the first fastener 21 refers to the connection between its undercut portion and the main housing structure of the Hall sensor 20, and the connecting portion of the second fastener 22 refers to the connection between its undercut portion and the main housing structure of the Hall sensor 20.

[0029] To further improve the reliability of the overall structure, two first fasteners 21 or two second fasteners 22 are arranged at intervals along the second direction. In the embodiment shown in the attached figure, two second fasteners 22 are arranged at intervals, while correspondingly, only one first fastener 21 is usually arranged. The first fasteners 21 and the second fasteners 22 are arranged in a triangular distribution, forming a stable and reliable three-point fixing structure. It can be understood that in the embodiment with two second fasteners 22, multiple first fasteners 21 can also be arranged, and any one first fastener 21 can work with two second fasteners 22 to form a triangularly distributed three-point fixing structure.

[0030] To ensure a simple and reliable overall structure, the Hall sensor 20 has multiple sensing areas spaced apart along its length (meaning that Hall sensors 20 detecting magnets at different locations share the same sensor housing, and each sensing area is used to sense a magnet arranged opposite to it). The filter module mounting groove 12 has a detachable and replaceable air conditioning filter module mounting structure. The air conditioning filter module mounting structure can be implemented using traditional methods, such as screw connection, snap-fit ​​connection, or screw and snap-fit ​​connection. In the embodiment shown in the attached figure, three sensing areas are designed, corresponding to the first sensing area 24, the second sensing area 25, and the third sensing area 26, respectively. Correspondingly, the air conditioning filter module is also designed with three different functions: the first air conditioning filter module 31, the second air conditioning filter module 32, and the third air conditioning filter module 33. Magnets are fixedly installed in different design positions in the three air conditioning filter modules. The first air conditioning filter module 31 has the first magnet 41 installed, the second air conditioning filter module 32 has the second magnet 42 installed, and the third air conditioning filter module 33 has the third magnet 43 installed. When the first air conditioning filter module 31 is installed in the filter module mounting groove 12, the first sensing area 24 can sense the first magnet 41, and the air conditioning control system can identify the installed air conditioning filter module as the first air conditioning filter module 31. When the second air conditioning filter module 32 is installed in the filter module mounting groove 12, the second sensing area 25 can sense the second magnet 42, and the air conditioning control system can identify the installed air conditioning filter module as the second air conditioning filter module 32. When the third air conditioning filter module 33 is installed in the filter module mounting groove 12, the third sensing area 26 can sense the third magnet 43, and the air conditioning control system can identify the installed air conditioning filter module as the third air conditioning filter module 33. It is understood that using the Hall sensor 20 and the magnet in combination to sense the installation position of the target object is a mature existing technology. The key improvement of this utility model lies in the specific installation structure of the Hall sensor 20, and does not involve the improvement of the computer program.
