Description

Technical Field

[0001] The utility model relates to the field of heat exchange, in particular to a sensor fixing device and an air conditioner. Background Art

[0002] When air conditioners use refrigerant, there's a safety hazard of refrigerant leaking into the indoor air, potentially igniting or even exploding. Therefore, relevant electrical safety standards strictly limit the amount of refrigerant that can be released within a confined space—that is, the refrigerant charge per unit. However, in multi-split air conditioners, which have a single outdoor unit connected in parallel with multiple indoor units, the amount of refrigerant charged per outdoor unit is large, making it difficult to meet the safety standard's refrigerant charge per unit. To address this issue, refrigerant leak detection sensors can be added to the indoor units to prevent leaks and control the air conditioner's on / off function. However, adding a refrigerant sensor to the indoor unit requires mounting it on a fixture on the unit. Current fixtures often rely on specific components within the indoor unit to create a mounting space for the sensor, forcing the sensor to be fixed to a specific location. This inflexible installation method is difficult to implement and difficult to disassemble or disassemble. If the indoor unit components near the leak point don't create a mounting space for the sensor, the sensor will be difficult to install. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0032] In order to solve the problem of poor installation adaptability of a refrigerant sensor on an air-conditioning unit in the prior art, the utility model provides a sensor fixing device and an air-conditioning unit.

[0033] like Figures 1 to 8 As shown, this embodiment provides a sensor fixing device, including a fixing bracket 10, the fixing bracket 10 has a receiving space for accommodating a sensor 20 and a mounting portion 12 for fixing to an external component, the mounting portion 12 has a plurality of mounting positions 121, and the structures of the plurality of mounting positions 121 are not exactly the same.

[0034] In this embodiment, a plurality of mounting positions 121 with different structures are provided on the mounting portion 12 of the fixing bracket 10, so that the connection between the sensor fixing device and the heat exchange equipment is not limited to one method, so that the sensor fixing device can not only fix the sensor 20 to the heat exchange equipment, but also, compared with the traditional method of relying on specific components of the heat exchange equipment to form the installation space of the refrigerant sensor, the installation position of the sensor fixing device of this embodiment is more flexible, so that different installation spaces can be taken into account, so that the sensor 20 can adapt to different installation positions on the heat exchange equipment, avoiding the difficulty of installing the sensor 20 due to the small space of the heat exchange equipment, interference from other components, etc., thereby improving the compatibility of the sensor fixing device and expanding its scope of application.

[0035] In this embodiment, the fixing bracket 10 has a clamping portion 1121, which is provided at the location of the accommodation space and is used to engage with the sensor 20. In other words, the clamping portion 1121 is not provided on the mounting portion 12, nor is it provided at other locations of the fixing bracket 10, but is provided at the accommodation space of the fixing bracket 10 for accommodating the sensor 20, such as at the side wall of the accommodation space, so as to facilitate the clamping with the sensor. Figure 2 、 Figure 3 As shown, the accommodation space of this embodiment is configured as a rectangle to match the outer shape of the sensor 20. The engaging portion 1121 is provided on the side wall of the accommodation space to facilitate engagement with the sensor 20 within the accommodation space. Of course, the shape of the accommodation space is not limited to a rectangle and can be adaptively adjusted to the outer shape of the sensor 20. If the sensor 20 is configured as another shape, such as a circle, the accommodation space can be adaptively adjusted to a circle.

[0036] In this embodiment, multiple snap-fitting portions 1121 are provided, and each snap-fitting portion 1121 is provided on a set of opposing surfaces of the accommodation space. This serves to position and secure the sensor 20, preventing it from falling off or moving. In this embodiment, the accommodation space has a set of opposing surfaces, and the snap-fitting portions 1121 are symmetrically arranged. Accordingly, corresponding structures are provided on the surface of the sensor 20 to cooperate with the snap-fitting portions 1121 to secure the sensor 20. Of course, if the accommodation space has multiple sets of opposing surfaces, snap-fitting portions 1121 can also be provided on each set to improve the reliability of the sensor 20.

[0037] In this embodiment, there are multiple snap-fitting parts 1121, and the snap-fitting parts 1121 include: a snap-fitting interface 1122 that passes through the fixed bracket 10 and connects to the accommodating space, so that the snap-fitting interface 1122 cooperates with the protrusion on the surface of the sensor 20 to achieve the positioning of the sensor 20; and / or a snap-fitting structure 1123 that bulges outward from the side wall of the accommodating space, and the snap-fitting structure 1123 can also cooperate with the protrusion on the surface of the sensor 20 to achieve the positioning of the sensor 20; and / or a snap-fitting groove formed on the surface of the accommodating space, so that the snap-fitting groove can cooperate with the recess on the surface of the sensor 20 to achieve the positioning of the sensor 20. Specifically, in this embodiment, the snap-fit ​​portion 1121 includes a snap-fit ​​interface 1122 and a snap-fit ​​structure 1123 that cooperates with a protrusion on the surface of the sensor 20 to achieve the positioning of the sensor 20. The protrusion on the surface of the sensor 20 includes a rib 23 and a snap 22, wherein the snap 22 cooperates with the snap-fit ​​interface 1122. The snap-fit ​​interface 1122 is configured as a rectangle, and the snap 22 is also configured as a rectangular protrusion. The snap 22 enters the card interface 1122 from the inside of the accommodating space and passes through the card interface 1122 to achieve snap connection. The card interfaces 1122 are provided on two opposite surfaces of the accommodating space. In this way, Figure 4 As shown, the sensor 20 cannot move along the width and length directions of the card interface 1122 in the accommodating space, thereby limiting the position of the sensor 20, so that the sensor 20 and the fixing bracket 10 are combined together to form a whole, so as to facilitate the connection and fixation of the sensor 20 with the external components. The number of card interfaces 1122 is not limited, and it is sufficient to achieve the card connection and limitation between the fixing bracket 10 and the sensor 20. In this embodiment, two card interfaces 1122 are set on the two opposite surfaces of the accommodating space. Of course, one card interface 1122 can also be set on the two opposite surfaces of the accommodating space, and set at the same position where the two card interfaces 1122 are set in this embodiment, so as to facilitate the cooperation with the buckle 22 on the surface of the sensor 20. That is to say, the two adjacent card interfaces 1122 of this embodiment are connected into one card interface 1122, which can also achieve cooperation with the two buckles 22 of the sensor 20. As shown Figure 2 As shown, the clamping structure 1123 is located on a side away from each other between two adjacent card interfaces 1122, and the clamping structure 1123 is configured as a long strip-shaped slot. Figure 1As shown, the ribs 23 are also arranged in a long strip shape. The ribs 23 are arranged on two opposite surfaces of the accommodating space, and two ribs 23 are arranged on each surface, so a total of four ribs 23 are arranged. The ribs 23 are located inside the clamping structure 1123, so that the sensor 20 can be further fixed and limited, preventing external vibrations from causing collisions between the sensor 20 and the fixing bracket 10 and generating abnormal noises. Considering that two of the four ribs 23 are arranged in the middle of the side of the sensor 20, and the other two are arranged at the ends of the sensor 20, the clamping structure 1123 of this embodiment is only provided one on each of the two opposite surfaces. Figure 2 A snap-fit ​​structure 1123 is provided in the middle position of the side of the accommodating space shown, that is, only two snap-fit ​​structures 1123 are provided in this embodiment, which respectively cooperate with the two ribs 23 provided in the middle position of the side of the sensor 20, and the other two ribs 23 directly cooperate with the surface of the accommodating space, so that part of the ribs 23 cooperate with the snap-fit ​​structure 1123, and part of the ribs 23 cooperate with the surface of the accommodating space, so as to further fix the sensor 20.

[0038] In this embodiment, the fixed bracket 10 is further provided with an escape opening 1111. The escape opening 1111 is connected to the accommodating space and is used to escape the air inlet boss 21 of the sensor 20. This leaves sufficient space for the air inlet of the sensor 20 to facilitate the entry and exit of leaked refrigerant, thereby avoiding affecting the detection sensitivity of the sensor 20. The escape opening 1111 of this embodiment is configured as a circle and is located between two opposing surfaces of the accommodating space. It passes through the fixed bracket 10, and the air inlet boss 21 of the sensor 20 extends from the interior of the accommodating space. Of course, the shape of the escape opening 1111 can be adjusted accordingly based on the shape of the air inlet boss 21 of the sensor 20. For example, when the air inlet boss 21 of the sensor 20 is configured as a square, the escape opening 1111 can be configured as a corresponding square.

[0039] In this embodiment, a limiting structure for limiting the position of the air inlet boss 21 is provided at the periphery of the avoidance opening 1111, thereby fixing the position of the air inlet boss 21 and preventing the air inlet boss 21 from rotating in the avoidance opening 1111 and affecting the detection sensitivity of the sensor 20, thereby improving the reliability of the fixation of the sensor 20.

[0040] In this embodiment, the limiting structure includes at least one of a limiting notch 1112 and a limiting rib. The air inlet boss 21 of the sensor 20 of this embodiment has four limiting protrusions 24 evenly distributed around the circular structure. Correspondingly, four limiting notches 1112 are evenly distributed around the avoidance opening 1111. Thus, the limiting protrusions 24 are located within the limiting notches 1112, not only leaving sufficient space for the air inlet of the sensor 20, but also limiting the position of the sensor 20, preventing it from rotating within the accommodation space. Of course, depending on the actual shape of the sensor 20, the limiting structure can also be provided as a limiting rib, or both the limiting notches 1112 and the limiting rib can be provided. For example, when the positioning rib of the air inlet boss 21 of the sensor 20 is located within a recessed portion to achieve a recessed portion around the perimeter, the perimeter of the avoidance opening 1111 is correspondingly provided as a limiting rib, thereby limiting the position of the sensor 20.

[0041] In this embodiment, the fixed bracket 10 includes a fixed enclosure 11 with a semi-enclosed structure, the fixed enclosure 11 forms an accommodating space, and the mounting portion 12 is arranged on the side of the fixed enclosure 11. In this way, the fixed enclosure 11 limits the sensor 20 in the accommodating space, and the mounting portion 12 fixes the sensor 20 and the fixed bracket 10 together with the external components.

[0042] In this embodiment, the fixed enclosure 11 includes a cover 111 and side panels 112. The cover 111 has a clearance opening 1111. The side panels 112 are multiple and relatively arranged at the edges of the cover 111. A snap-fit ​​portion 1121 is formed at the connection between the cover 111 and the side panels 112. The fixed enclosure 11 of this embodiment forms a storage space through the rectangular cover 111 and the two rectangular side panels 112. The snap-fit ​​portions 1121 are provided at the corners of the cover 111 and the side panels 112. This allows the sensor 20 to be fixed without limiting its length, allowing the fixed bracket 10 to accommodate sensors 20 of different lengths, thereby improving the adaptability of the fixed bracket 10. The mounting portion 12 is provided on the side of the side panel 112 facing away from the storage space, thereby providing a mounting position 121 while avoiding the storage space, facilitating the installation and maintenance of the sensor 20. Of course, depending on the actual situation, the side panels 112 can also be provided with three, four, etc., as long as they can achieve the desired fixation of the sensor 20.

[0043] In this embodiment, the cover plate 111, the side plate 112 and the mounting portion 12 are integrally formed, and are bent and connected in the order of the mounting portion 12, the side plate 112, the cover plate 111 and the side plate 112 to fix the sensor 20; the mounting portion 12 of this embodiment is configured as a rectangular flat plate, and the mounting portion 12 extends along the length direction of the side plate 112, that is, the long side of the mounting portion 12 is bent and connected to the long side of the side plate 112, and a plurality of mounting positions 121 are spaced apart along the extension direction of the mounting portion 12, that is, the long side direction, so that the fixing bracket 10 can be compatible with a variety of installation methods, thereby improving the scope of application of the fixing bracket 10. It should be noted that the length direction of the side plate 112, the extension direction of the mounting portion 12, and the setting direction of the plurality of mounting positions 121 are consistent, and are all Figure 3 The up and down directions in .

[0044] In this embodiment, the mounting position 121 includes at least one of a card interface, a screw hole, an avoidance through hole, a buckle, and a positioning column. The mounting position 121 of this embodiment is configured in a manner in which two structures, screw holes and avoidance through-holes, coexist. Specifically, two screw holes are symmetrically arranged at both ends along the length direction of the mounting portion 12, and two avoidance through-holes are symmetrically arranged adjacent to the screw holes along the direction in which the two screw holes approach each other. In this way, the fixing bracket 10 can not only cooperate with the through-holes of the external component, so that the screws pass through the through-holes of the external component and are fixed to the screw holes of the fixing bracket 10, but also when the external component does not have space for the screws to be inserted, it can also cooperate with the screw holes of the external component, so that the screws pass through the avoidance through-holes of the fixing bracket 10 and are fixed to the screw holes of the external component. Moreover, when the external component does not have the conditions for setting screw holes and does not meet the space for cooperating with the screw holes of the fixing bracket 10, screws can also be used to pass through the through-holes of the external component and the avoidance through-holes of the fixing bracket 10 and be fixed with nuts, so that the fixing bracket 10 can meet multiple fixing methods, so that the fixation of the fixing bracket 10 does not have to be limited to the structural form of a single external component, so that it can cooperate with external components of multiple different structural forms, thereby improving the flexibility of the fixing bracket 10. The two screw holes in the mounting portion 12 can be replaced with a single screw hole and a positioning post, similarly securing the fixing bracket 10 to the external component. Similarly, the two clearance holes in the mounting portion 12 can be replaced with a single clearance hole and a positioning post. Of course, the mounting position 121 can also be configured as a card interface, snap-fit ​​structure, or other structural form. By providing a corresponding matching structure on the external component, the fixing bracket 10 and the external component can be secured, thereby securing the sensor 20 to the external component.

[0045] It should be noted that the heat exchange equipment in this embodiment refers to equipment such as air conditioners, which can be outdoor units, or other indoor units such as patio units, wall-mounted units, and duct units. Figure 5 The above is illustrated by taking a roof crane as an example.

[0046] like Figure 5 As shown, this embodiment also provides an air conditioner, including a sensor 20 and the above-mentioned sensor fixing device, so that the sensor 20 is fixed to the air conditioner, that is, the above-mentioned external component, through the sensor fixing device, ensuring the reliability of the connection between the sensor 20 and the sensor fixing device, so that the sensor 20 will not move relative to the sensor fixing device and the air conditioner, and the setting of the mounting portion 12 makes the installation and disassembly of the sensor 20 more convenient and flexible.

[0047] In this embodiment, sensor 20 is a refrigerant sensor; although refrigerants such as R32 and R290 are relatively environmentally friendly during use, they are all flammable refrigerants. When the air conditioner uses these flammable refrigerants, there is a safety hazard of refrigerant leaking into the indoor air and then being ignited or even exploded. This requires the installation of a fixed refrigerant sensor. The sensor fixing device of this embodiment can firmly fix the refrigerant sensor to the air conditioner, so that the refrigerant sensor does not fall off at the installation position, and the air inlet boss 21 of the refrigerant sensor does not move, thereby stabilizing the detection accuracy of the refrigerant sensor and ensuring its effectiveness. In addition, this embodiment combines the sensor fixing device and the refrigerant sensor into a whole, and then installs the whole on the air conditioner, thereby facilitating the installation and disassembly of the refrigerant sensor on the heat exchange equipment.

[0048] like Figure 6 、 Figure 7 、 Figure 8 As shown, the air conditioner of this embodiment further includes a mounting plate 30, which is provided with mounting holes 31 for corresponding to the mounting positions 121 of the sensor fixture. Depending on the space surrounding the mounting plate 30, the mounting holes 31 can be provided as two screw holes, two through holes, or one screw hole and one through hole, so as to correspond to the mounting positions 121 of the mounting portion 12. This allows bolts to pass through the mounting holes 31 and the mounting positions 121 to secure the mounting plate 30 and the sensor fixture together.

[0049] The installation and fixing process of the refrigerant sensor, sensor fixing device and mounting plate 30 of this embodiment is as follows: 1. The refrigerant sensor and the fixing bracket 10 are combined to form a whole. Figure 4As shown, the fixing bracket 10 is buckled on the top of the refrigerant sensor, and the buckle 22 of the sensor 20 extends into the card interface 1122 of the fixing bracket 10 and is snapped onto the card interface 1122, so that the refrigerant sensor can be buckled on the fixing bracket 10. In addition, the two ribs 23 on the refrigerant sensor cooperate with the snap-on structure 1123 of the fixing bracket 10, and the gap between the snap-on structure 1123 and the rib 23 is small. In addition, the two ribs 23 away from the center of the sensor 20 cooperate with the inner surface edge of the fixing bracket 10, so that the refrigerant sensor is firmly fixed on the fixing bracket 10 and cannot move, preventing external vibration from causing collision between the refrigerant sensor and the fixing bracket 10 and causing abnormal noise. The inlet boss of the refrigerant sensor passes through the avoidance opening 1111 of the fixing bracket 10, leaving sufficient space for the air inlet of the refrigerant sensor to facilitate the entry and exit of leaked refrigerant, thereby ensuring the refrigerant sensor. Detection sensitivity, while avoiding four limiting structures designed around the opening 1111, which cooperate with the limiting protrusion 24 of the refrigerant sensor to play a limiting role; 2. After the refrigerant sensor and the fixing bracket 10 are assembled, they are installed on the mounting plate 30. The installation position should be connected to the refrigerant leakage point to detect the leaked refrigerant. Generally, the elbows and pipe welding points of the air conditioner are often considered to be the refrigerant leakage points. Therefore, the refrigerant sensor is generally installed near these leakage points. In addition, the refrigerant sensor is required to be easy to install and convenient to disassemble and detect on the air conditioner. The fixing bracket 10 should be reliable. After installation, the position of the refrigerant sensor air inlet cannot be moved to avoid changes in detection accuracy. In order to cope with various different spatial structures of the air conditioner, the mounting part 12 of the fixing bracket 10 is provided with screw holes and avoidance through holes. During installation, select one of the structures and use screws to fix the fixing bracket 10 to the mounting plate 30, such as Figure 7 、 Figure 8 As shown in the figure, there are two installation methods: one is to fix the screw through the through hole on the mounting plate 30 to the screw hole of the fixing bracket 10, and the other is to fix the screw through the avoidance through hole of the fixing device to the screw hole on the mounting plate 30. Figure 5As shown, the fixed position of the refrigerant sensor in this embodiment is not suitable for inserting screws into the pipe end. To remove the refrigerant sensor, it is necessary to remove the mounting plate 30. Since the mounting plate 30 is used to fix the heat exchanger to the air conditioner, removing the mounting plate 30 is dangerous. Therefore, the avoidance hole of the fixing bracket 10 is not suitable for installing the refrigerant sensor in this embodiment. On the back of the mounting plate 30, there is a large gap between the heat exchanger and the fan blade. To prevent the fan blade from interfering with the screw insertion of the refrigerant sensor, it is also possible to remove the fan blade first and then remove the refrigerant sensor. Therefore, in this embodiment, the screw holes in the mounting portion 12 can be selected, and the back of the screw mounting plate 30 can be screwed through and fixed to the screw holes in the fixing bracket 10 to fix the refrigerant sensor to the mounting plate 30. In this way, during after-sales inspection and disassembly, the refrigerant sensor can be removed by directly removing the screws from the back of the mounting plate 30. Similarly, the refrigerant sensor can be fixed. It should be noted that the "multiple" in the above embodiments refers to at least two.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] 1. Solve the problem of poor installation adaptability of refrigerant sensors on air-conditioning units in the existing technology;

[0052] 2. By providing multiple mounting positions with different structures on the mounting portion of the fixing bracket, the connection between the sensor fixing device and the heat exchanger is not limited to one method, so that the sensor fixing device can not only fix the sensor to the heat exchanger, but also, compared with the traditional method that relies on specific components of the heat exchanger to form the installation space for the refrigerant sensor, the installation position of the sensor fixing device of this embodiment is more flexible, thereby taking into account the different installation spaces of the heat exchanger, so that the sensor can adapt to different installation positions on the heat exchanger, avoiding the difficulty of sensor installation due to the small space of the heat exchanger, interference with other components, etc.

[0053] 3. Improve the compatibility of sensor fixtures and expand their scope of application.
