[0050] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0051] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and arrangements of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can recognize the applicability of other processes and / or the use of other materials.

[0052] The following refers to Figures 1 - 13 to describe the refrigerant sensor bracket 4 according to an embodiment of the first aspect of the present invention.

[0053] The above-mentioned refrigerant sensor bracket 4 is used in the air conditioner 100 and is used to connect the refrigerant sensor 3 to the air conditioner 100.

[0054] Generally, as Figure 1 shown, the air conditioner 100 includes a housing 1, and the housing includes a chassis 10.

[0055] As Figures 2 - 4 shown, the refrigerant sensor bracket 4 is disposed on the lower side inside the air conditioner 100.

[0056] This is because, as Figure 3 shown, the welded pipes and bent pipes of the evaporator in the air conditioner 100 are the main positions where refrigerant leakage occurs, and the specific gravity of the refrigerant is heavier than that of air. Therefore, the leaked refrigerant will sink downward until it sinks to the bottom inside the air conditioner 100 and converges in a place with a larger pipe-walking space. Therefore, installing the refrigerant sensor 3 inside the housing 1 of the air conditioner 100 and at the bottom of the air conditioner 100 is more conducive to the accuracy of the refrigerant sensor 3 during operation and improves the detection accuracy of the refrigerant sensor 3.

[0057] As Figure 4 and Figures 10 - 13 shown, the refrigerant sensor bracket 4 according to some embodiments of the present invention includes a bracket body 41. The bracket body 41 is used to form the basic body of the refrigerant sensor bracket 4.

[0058] As Figure 2 and Figures 10 - 11As shown, the refrigerant sensor bracket 4 further includes a positioning post 42 and a threaded connecting post 43. The positioning post 42 is provided on the bracket body 41 and is located on one side of the bracket body 41. The positioning post 42 extends from the outer surface of the bracket body 41 in a direction away from the bracket body 41, forming an outwardly protruding positioning post 42, which facilitates the preliminary positioning of the refrigerant sensor 3. The connecting post 43 is provided on the bracket body 41 and is located on the same side as the positioning post 42 to connect the refrigerant sensor 3. The positioning post 42 functions to perform preliminary positioning when installing the refrigerant sensor 3. After the refrigerant sensor 3 obtains preliminary positioning, it is then connected to the refrigerant sensor 3 through the threaded connecting post 43 to fix the refrigerant sensor 3 to the refrigerant sensor bracket 4.

[0059] It should be noted that one end of the positioning post 42 close to the bracket body 41 is the tail, and the end of the positioning post 42 away from the bracket body 41 is the head. The cross-section of the positioning post 42 from the head to the tail shows a gradually increasing trend. This is beneficial for positioning, as the head of the positioning post 42 is more likely to align with and enter the corresponding positioning hole 52 of the refrigerant sensor 3. When the positioning hole 52 reaches the tail, the cross-section of the tail exactly matches the size of the positioning hole 52, making the positioning more stable and less likely to shake.

[0060] Optionally, the friction coefficient of the outer surface of the head is lower than that of the outer surface of the tail, further improving the installation speed. After the corresponding positioning hole 52 of the refrigerant sensor 3 enters the positioning post 42 and abuts against the tail with a larger friction coefficient, the stability after positioning can be effectively improved.

[0061] Optionally, the cross-section of the positioning post 42 includes but is not limited to being set as a circle, an ellipse, a rectangle and other polygons. At the same time, the corresponding positioning hole 52 of the refrigerant sensor 3 is also configured into a structure adapted to the positioning post 42.

[0062] Specifically, the threaded structure on the connecting post 43 can be either an internal thread or an external thread. When the connecting post 43 is provided with an internal thread, the screw post is passed through the connecting post 43, and the external thread on the screw post is threadedly fixed to the internal thread of the connecting post 43 to achieve locking.

[0063] When the connecting post 43 is provided with an external thread, after the refrigerant sensor 3 is passed through the connecting post 43, it is connected through the internal thread of the nut cooperating with the external thread on the connecting post 43 to fix the refrigerant sensor 3.

[0064] Furthermore, a gasket is provided between the bolt and the connecting post 43 or between the nut and the connecting post 43 to fill the irregular gaps, increase the contact area, and play a role in preventing loosening.

[0065] Combined with Figures 4 - 5 、 Figures 11 - 13 , a wire passing hole 411 is also provided on the bracket body 41.

[0066] The wire hole 411 passes through the thickness direction of the bracket body 41, and is open toward one side of the bracket body 41. The wire hole 411 is used to accommodate the wire harness and facilitate the installation of the wire harness, thereby improving the neatness of the wire harness. The cross-section of the wire hole 411 perpendicular to the direction in which the wire harness passes can be circular, rectangular or any other shape.

[0067] Combination Figures 4 - 7 , Figures 12 - 13 The bracket body 41 also includes a wire guard side plate 4111. The wire guard side plate 4111 is arranged on the bracket body 41 on the same side as the positioning column 42. The wire guard side plate 4111 extends along the edge of the wire hole 411 in a direction away from the bracket body 41. A wire passage is formed in the wire guard side plate 4111. The wire passage is used to guide the entire wiring harness through the wire hole 411, so that the wiring harness passes through the refrigerant sensor bracket 4 more smoothly. At the same time, the wire guard side plate can constrain the position of the wiring harness to prevent the wiring harness from occupying additional space. It is worth noting that both the wire hole 411 and the wire guard side plate 4111 form an open end toward one side of the bracket body 41, so that the wiring harness enters the wire passage channel uniformly from the open end, which not only improves the neatness of the wiring harness, but also improves the installation convenience and efficiency.

[0068] Combination Figures 9 - 11 The bracket body 41 is provided with an armor wire through hole 412 that penetrates in the thickness direction of the bracket body 41 for passing the armor wire (not shown). The armor wire here is a wire harness that is required to be installed when installing the air conditioner in some countries and regions. The connection position and working principle of the armor wire are common knowledge and will not be described here.

[0069] Furthermore, the diameter of the armor wire through hole 412 matches the armor wire as much as possible, and the range of movement of the armor wire is limited while guiding the armor wire to pass through, so as to avoid the problem of electrical components and armor wire falling off caused by the shaking of the armor wire being transmitted to the inside.

[0070] Combination Figures 10 - 12 The bracket body 41 also includes a filling plate 4121, which is located in the armor wire through-hole 412, and the outer periphery of the filling plate 4121 is connected to the inner wall of the armor wire through-hole 412 through at least one connecting rib 4122, so that the filling plate 4121 is temporarily arranged in the armor wire through-hole 412.

[0071] Based on the installation rules of armored wires in different countries, some countries require the installation of armored wires, while some do not. When the air conditioner 100 enters some countries where the installation of armored wires is not required, the filling plate 4121 provided in the armored wire perforation 412 does not need to be removed. The filling plate 4121 is arranged in the armored wire perforation 412 through the connecting ribs 4122 to enhance the strength of the refrigerant sensor bracket 4. When the air conditioner 100 enters a country where the installation of armored wires is required, the installer cuts off the connecting ribs 4122 and removes the filling plate 4121 to complete the installation of the armored wire. Further, before installing the armored wire, the filling plate 4121 also plays a role in strengthening the firmness of the refrigerant sensor 3.

[0072] Combined with Figure 11 , the bracket body 41 further includes strap fixing parts 413 located on both sides of the armored wire perforation 412. The strap fixing parts 413 on both sides are respectively strip-shaped jacks 4131 and strap fixing holes 4132, so that one end of the strap can be inserted into the jack 4131 and the other end is connected to the strap fixing hole 4132, and the armored wire is fixed to one side of the bracket body 41 of the refrigerant sensor bracket 4 through the strap fixing parts 413 on both sides.

[0073] Combined with Figure 10 , Figure 12 , the bracket body 41 further includes a reinforcing boss 414 provided on the bracket body 41. The reinforcing boss 414 is arranged on one side of the bracket body 41 and is on the same side as the connecting column 43.

[0074] The reinforcing boss 414 extends from the surface of the bracket body 41 towards the side away from the bracket body 41. The function of the reinforcing boss 414 is to abut against the refrigerant sensor 3. It can be known that after the refrigerant sensor 3 and the refrigerant sensor bracket 4 are positioned, when the refrigerant sensor 3 is threadedly connected to the connecting column 43, it is continuously close to the bracket body 41 under the external force of the threaded screwing, so that an angle is generated between the refrigerant sensor 3 and the bracket body 41. This angle will cause the refrigerant sensor 3 to be skewed during the installation process. The length of the outward extension of the reinforcing boss 414 is lower than the length of the outward extension of the connecting column 43. When the refrigerant sensor 3 is connected to the connecting column 43, the side of the refrigerant sensor 3 close to the bracket body 41 abuts against the outer edge surface of the reinforcing boss 414, ensuring the perpendicularity of the installation of the refrigerant sensor 3 and the connecting column 43, improving the stability of the threaded connection, avoiding the risk of the refrigerant sensor 3 falling off from the refrigerant sensor bracket 4, and ensuring the installation quality.

[0075] It should be noted that regarding the shape of the reinforcing boss 414, since the function of the reinforcing boss 414 is to abut, the height of the reinforcing boss 414 needs to be lower than that of the connecting column 43. The shape of the cross-section of the reinforcing boss 414 perpendicular to the bracket body 41 includes, but is not limited to, an annular shape, and the connecting column 43 is arranged within the ring. Further, the threaded connecting column 43 is provided on the reinforcing boss 414, that is: the connecting column 43 is arranged at the end of the reinforcing boss 414 away from the bracket body 41. When connecting, the refrigerant sensor 3 passes through the connecting column 43 and abuts against the reinforcing boss 414.

[0076] Combined with Figure 10 , Figure 12 , an anti-rotation pin 4141 is further provided on the end face of the connecting column 43 of the reinforcing boss 414. The anti-rotation pin 4141 can effectively limit the radial rotation of the refrigerant sensor 3 during the installation process. Therefore, it is not necessary to occupy both hands of the installer for fixation at the same time, but one hand can be freed for operation, so as to improve the assembly efficiency.

[0077] The refrigerant sensor bracket 4 further includes at least one arm provided on the bracket body 41. The arm extends outward along the bracket body 41, and a connecting portion 441 for connecting to the chassis 10 of the air conditioner 100 is provided on the arm.

[0078] The connection between the connecting portion 441 and the chassis 10 can adopt detachable connection methods such as threaded connection, snap connection, clamping connection, magnetic attraction connection, etc. By providing the arm, on the premise of a relatively small overall occupied space, the connection position can be expanded by using the arm to solve the problem of connecting the refrigerant sensor bracket 4 to the air conditioner 100, and the vibration generated during use is effectively buffered through the connection of the arm, attenuating the influence of the vibration on the refrigerant sensor 3 and improving the supporting ability of the refrigerant sensor bracket 4. Furthermore, through the detachable connection method, it is convenient to disassemble and assemble the refrigerant sensor bracket 4. When installation / dismantling is required, only the arm needs to be connected / dismantled to the chassis 10, which is convenient for replacing the refrigerant sensor 3 between different air conditioners 100 and improves the flexibility of use of the refrigerant sensor bracket 4. In this way, multiple air conditioners 100 can use the same refrigerant sensor 3 to reduce the usage cost of the refrigerant sensor 3.

[0079] In some embodiments, the connecting portion 441 adopts a connecting hole, so that the detachable connection between the arm and the inside of the air conditioner 100 is realized by means of threaded connection with bolts and nuts.

[0080] Combined with Figures 10 to 13, the support arm includes a first support arm 44 and a second support arm 45. It can be understood that the first support arm 44 and the second support arm 45 can be installed on the same side / opposite side / adjacent side of the bracket body 41 to achieve the installation effect. Adjusting the installation positions of the first support arm 44 and the second support arm 45 according to the structure of the chassis 10 of the air conditioner 100 is known to those of ordinary skill in the art and will not be described in detail here.

[0081] In this embodiment, as Figures 10 to 13 shown, the first support arm 44 extends along the lower side of the bracket body 41, and the first support arm 44 and the positioning post 42 are on the same side; the second support arm 45 is arranged along the upper side of the bracket body 41, and the second support arm 45 is connected to the upper side edge of the bracket body 41. The first support arm 44 and the second support arm 45 are connected to the chassis 10 of the air conditioner 100, so that the refrigerant sensor bracket 4 is fixed on the chassis 10 of the air conditioner 100. Connection parts 441 are provided on the first support arm 44 and the second support arm 45, and the structure of the connection parts 441 adopts the existing structure in the prior art and will not be elaborated here.

[0082] In some embodiments, as Figure 5 , Figure 7 , Figure 9 , Figures 12 - 13 shown, the first support arm 44 extends outward perpendicular to the bracket body 41, and the second support arm 45 extends obliquely away from the first support arm 44 to adapt to the structure of the chassis 10 inside the air conditioner 100. Specifically, as Figure 12 shown, a fold angle is formed between the second support arm 45 and the bracket body 41, and a reinforcing plate 451 is formed along the fold angle of the second support arm 45. The reinforcing plate 451 is used to strengthen the support strength between the second support arm 45 and the bracket body 41, and improves the stability of the refrigerant sensor 3 after installation.

[0083] Combined with Figures 9 to 13 , in some embodiments, the refrigerant sensor bracket 4 further includes a hanging buckle part 46 arranged on the upper side edge of the bracket body 41 for connecting the internal chassis 10 of the air conditioner 100 to further improve the installation stability.

[0084] Furthermore, as Figure 12 shown, the hanging buckle part 46 extends outward perpendicular to the upper side edge of the bracket body 41, and a first limiting part 461 and a second limiting part 462 are arranged at intervals on the side of the hanging buckle part 46 away from the bracket body 41. A first limiting part 463 is jointly formed among the first limiting part 461, the second limiting part 462 and the hanging buckle part 46. The first limiting part 463 is in an open shape, which is beneficial to fit with the chassis 10 during installation. When a part of the chassis 10 is placed inside the first limiting part 463, the first limiting part 461 and the second limiting part 462 limit its displacement in the front and rear directions, enhancing the stability of the refrigerant sensor bracket 4 after installation.

[0085] Combined with Figure 10 、 Figure 12 Optionally, there is at least one reinforcing rib 464 between the first limiting member 461 and the hanging portion 46. The reinforcing rib 464 is triangular, one side of the triangle is connected to the hanging portion 46, and the other adjacent side is connected to the first limiting portion 463, so that the reinforcing rib 464 is supported on the side away from the first limiting portion 463 to enhance the strength of the first limiting member 461.

[0086] Further optionally, the first limiting portion 463 is configured to adapt to the corresponding chassis 10 structure to increase the contact area and contact reliability between the refrigerant sensor bracket 4 and the chassis 10.

[0087] Among them, the number of the hanging portions 46 is not limited, and one or more can be set. Multiple hanging portions 46 are more likely to ensure the relative position accuracy between the refrigerant sensor bracket 4 and the chassis 10. Multiple hanging portions 46 can be arranged at intervals on the upper side and / or the lower side of the bracket body 41.

[0088] In some embodiments, combined with Figures 10 - 11 、 Figure 13 ,the refrigerant sensor bracket 4 further includes a positioning groove 47. The positioning groove 47 is provided through the thickness of the bracket body 41 and is opened on the upper side and / or the lower side of the bracket body 41, mainly for adaptively connecting to the chassis 10 structure.

[0089] In some embodiments, combined with Figure 10 、 Figure 13 ,the refrigerant sensor bracket 4 further includes a side plate 48 connected to one side of the bracket body 41. The side plate 48 is arranged on the left side of the vertical side of the bracket body 41, and the side plate 48 strengthens the strength of the bracket body 41. Specifically, the side plate 48 is trapezoidal, the lower bottom of the trapezoid is close to the bracket body 41, and the upper bottom of the trapezoid is far from the bracket body 41. More specifically, as Figure 12 shown, the side plate 48 is further provided with an arc-shaped groove 481. The groove 481 extends along the vertical waist of the trapezoid, and the groove 481 does not penetrate the thickness of the side plate 48.

[0090] Next, with reference to Figures 1 - 9 ,the air conditioner 100 according to the second aspect embodiment of the present invention will be described.

[0091] The air conditioner 100 includes a housing 1, an electric control box 2, a refrigerant sensor 3, and a refrigerant sensor bracket 4. The refrigerant sensor bracket 4 is arranged in the housing 1 and located at the bottom. The refrigerant sensor bracket 4 is the refrigerant sensor bracket 4 in the first aspect embodiment of the present application.

[0092] With such a setting, the refrigerant sensor 3 can be specifically set at the main positions where refrigerant leakage may occur, thereby improving the accuracy of the refrigerant sensor 3 in use.

[0093] As Figure 2 , Figures 4 - 5 shown, the air conditioner 100 further includes a sensor connection base 5. The refrigerant sensor 3 is mounted on the refrigerant sensor bracket 4 through the sensor connection base 5. As Figure 5 shown, the sensor connection base 5 is provided with positioning holes 52 and screw holes 53 that respectively cooperate with the positioning posts 42 and connection posts 43. Through the fixed connection at two points, the refrigerant sensor 3 is fixed to the refrigerant sensor bracket 4.

[0094] In some embodiments, the refrigerant sensor bracket 4 is an independent part, or the refrigerant sensor bracket 4 is integrally formed on the electronic control box 2.

[0095] Next, refer to the attached Figures 1 - 13 description of the air conditioner 100 according to a specific embodiment of the present application.

[0096] As Figures 1 - 9 shown, the air conditioner 100 includes: a housing 1, an electronic control box 2, a refrigerant sensor 3, a refrigerant sensor bracket 4, and a sensor connection base 5.

[0097] The air conditioner 100 is a wall-mounted air conditioner. The length direction of the housing 1 extends horizontally. The housing 1 includes a chassis 10. The chassis 10 is provided at the lower part of the housing 1. The electronic control box 2 and the refrigerant sensor 3 are both provided on the same side of the chassis 10 and at the bottom of the chassis 10. The refrigerant sensor 3 is connected to the sensor bracket through the sensor connection base 5. Further, the refrigerant sensor bracket 4 is connected to the chassis 10 so that the refrigerant sensor 3 is installed at the bottom of the chassis 10 and its position is at the lower side inside the housing 1.

[0098] As Figures 10 - 13 shown, the refrigerant sensor bracket 4 includes: a bracket body 41, a positioning post 42, a connection post 43, a first arm 44, a second arm 45, a hanging portion 46, a positioning groove 47, and a side plate 48.

[0099] The bracket body 41 is generally rectangular, and its length direction extends horizontally. The positioning post 42 and the connection post 43 are provided on the front surface of the bracket body 41, and both the positioning post 42 and the connection post 43 extend away from the bracket body 41.
