[0001] This disclosure relates to the field of air purification technology, specifically to a filter assembly and an air conditioner. Background Technology

[0002] Air conditioner filter assemblies are generally equipped with filters to treat the intake air. In addition, filter assemblies are usually equipped with sensors to detect and monitor air quality. In related technologies, the sensors are mounted on the filter assembly via sensor brackets. However, the sensor brackets may block part of the air outlet, thus affecting the sensor's detection performance. Utility Model Content

[0003] The purpose of this disclosure is to provide a filter assembly and an air conditioner, wherein the sensor fixing structure can form a clearance space with the convection hole, thereby improving the detection accuracy of the sensor and at least partially solving the problems in the related art.

[0004] To achieve the above objectives, the first aspect of this disclosure provides a filter assembly, comprising: a lower cover including an air outlet; and a mounting bracket for mounting a sensor, the mounting bracket being offset between the air outlets.

[0005] Optionally, the mounting bracket is configured such that, after the sensor is installed, there is a gap between the sensor and the air outlet in a first direction, wherein the first direction refers to the thickness direction of the filter assembly.

[0006] Optionally, the mounting bracket includes a limiting bracket and a fixing bracket. The limiting bracket is used to limit the sensor in at least one of a first direction, a second direction, or a third direction, wherein the second direction refers to the width direction of the filter assembly, and the third direction refers to the length direction of the filter assembly; the fixing bracket is used to fix the sensor.

[0007] Optionally, the limiting bracket includes a supporting rib and a limiting rib, the bottom end of the supporting rib is fixedly connected to the lower cover between the air outlets, the supporting rib extends along a first direction, and the limiting rib is disposed on the inner side of the supporting rib for abutting and limiting the sensor; and / or the fixing bracket includes studs, at least a portion of the bottom end of the studs is fixedly connected to the lower cover to avoid the air outlets.

[0008] Optionally, the limiting rib includes a first limiting rib, which is used to limit the sensor in a second direction.

[0009] Optionally, the limiting rib includes a second limiting rib, which is located above the first limiting rib and is used to limit the sensor in a first direction.

[0010] Optionally, the mounting bracket includes two limiting brackets and two fixing brackets, the projections of the two limiting brackets and the two fixing brackets in the first direction are rectangular, and the two limiting brackets and the two fixing brackets are alternately arranged at the corners of the mounting bracket.

[0011] Optionally, the mounting bracket includes two limiting brackets and one fixing bracket, the projections of the two limiting brackets and the fixing bracket in the first direction are triangular, and the two limiting brackets are connected by connecting ribs.

Detailed Implementation

[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, directional terms such as "first direction" refer to the thickness direction of the filter assembly; see reference for details. Figure 2 The "X" direction refers to the width of the filter assembly, and the "second direction" refers to the width direction of the filter assembly. Please refer to [the relevant documentation / reference]. Figure 2 In the Y direction, "third direction" refers to the length direction of the filter assembly; for details, please refer to [reference needed]. Figure 2 In the Z-direction, "inner" and "outer" refer to the contours of the component itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description referring to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0028] In related technologies, air conditioner filter assemblies are generally equipped with filters to treat the intake air. In addition, filter assemblies are usually equipped with sensors to detect and monitor air quality. In related technologies, the sensors are mounted on the filter assembly via sensor brackets. The sensor brackets may block part of the air outlet, thereby affecting the detection effect of the sensors.

[0029] To solve the above technical problems, such as Figures 1-5 As shown, the first aspect of this disclosure provides a filter assembly, including: a lower cover 1 and a mounting bracket 2, the lower cover 1 including an air outlet 11; the mounting bracket 2 is used to mount a sensor 3, and the mounting bracket 2 is offset between the air outlet 11.

[0030] By using the above technical solution, by setting an air outlet 11 and a mounting bracket 2 on the lower cover 1, the mounting bracket 2 is offset from the air outlet 11, and the mounting bracket 2 is used to install the sensor 3, thereby avoiding the sensor 3 from blocking the air outlet 11 too much, so that the sensor 3 can fully contact the air and improve the detection quality.

[0031] It is understood that the above-mentioned filter assembly also includes an upper cover (not shown in the figure) and a sensor 3. The upper cover is provided with an air inlet hole, through which air enters and exits through the air outlet hole 11. The first direction is the direction of air flow. A receiving cavity for accommodating the sensor 3 is formed between the upper cover and the lower cover 1. The mounting bracket 2 is located in the receiving cavity, and the sensor 3 is fixed to the mounting bracket 2. In this way, the air around the air conditioner can enter the receiving cavity through the air inlet hole of the upper cover, be detected by the sensor 3, and then be discharged through the air outlet hole 11 of the lower cover 1.

[0032] In addition, to facilitate air intake and exhaust, the air outlet 11 can be arranged in an array on the lower cover 1. Similarly, the air inlet can also be arranged in an array on the upper cover. The air outlet 11 can also be arranged in a one-to-one correspondence with the air inlet.

[0033] Of course, a filter installation cavity is also provided between the lower cover 1 and the upper cover. The filter installation cavity is spaced apart from the receiving cavity. The filter is installed in the filter installation cavity to filter the air at the air return vent of the air conditioner.

[0034] To ensure that the sensor 3 mounted on the mounting bracket 2 has sufficient contact with the air, in some feasible embodiments, the mounting bracket 2 is configured such that after the sensor 3 is installed, there is a gap 4 between the sensor 3 and the air outlet 11 in a first direction. The first direction refers to the thickness direction of the filter assembly. (See reference for details.) Figure 2 In the X direction, the sensor 3 and the air outlet 11 have a gap 4 in the first direction, which allows the sensor 3 to have enough space to contact the air after installation. That is, after the external air enters the filter assembly, it can be identified by the sensor 3 through the gap 4 and the air can be detected, thus improving the detection quality.

[0035] To facilitate the fixed installation of sensor 3 on the lower cover 1, in some feasible embodiments, the mounting bracket 2 includes a limiting bracket 21 and a fixing bracket 22. The limiting bracket 21 limits the sensor 3 in at least one of a first direction, a second direction, or a third direction. The fixing bracket 22 is used to cooperate with the connection hole of sensor 3 to fix the limited sensor 3 on the mounting bracket 2. Here, the first direction refers to the thickness direction of the filter assembly, the second direction refers to the width direction of the filter assembly, and the third direction refers to the length direction of the filter assembly. The specific details of the first direction can be found in [reference needed]. Figure 2 For details on the X-direction and the second direction, please refer to [the relevant documentation / reference]. Figure 2 For details on the Y-direction and the third-direction, please refer to [the relevant documentation / reference]. Figure 2The Z-direction, X-direction, Y-direction and Z-direction are set to be perpendicular to each other.

[0036] In some feasible implementations, the limiting bracket 21 may include a supporting rib 211 and a limiting rib 212. The number of supporting ribs 211 and limiting ribs 212 can be multiple, specifically arranged according to the installation requirements of the sensor 3. The bottom end of the supporting rib 211 is fixedly connected to the lower cover 1 between the air outlets 11. The projection of the supporting rib 211 in the first direction can be V-shaped or rectangular. The bottom end of the supporting rib 211 can be located in the gap between the air outlets 11, allowing the supporting rib 211 to avoid the air outlets 11. The supporting rib 211 extends along the first direction, thereby forming a raised portion in the first direction, so that the sensor 3 mounted on the mounting bracket 2 can form a gap 4 between itself and the air outlet 11. The limiting rib 212 can be located inside the supporting rib 211 for contact and limiting with the sensor 3. The limiting rib 212 may include a first limiting rib 213, which is used to limit the sensor 3 in the second direction. The first limiting rib 213 may be disposed at the top of the support rib 211. The first limiting rib 213 may be configured to extend along the first direction. When the sensor 3 is installed, the side of the first limiting rib 213 in the second direction abuts against the sensor 3 to limit the sensor 3 in the second direction.

[0037] In addition, the fixing bracket 22 may include studs, with at least a portion of the studs having their bottom ends obstructing the air outlet 11 and being fixedly mounted to the lower cover 1, such as... Figure 4 As shown, the bottom end of the stud is positioned between the four air outlets 11, and part of the edge of the stud blocks part of the air outlets 11. The stud has a screw hole, and the fastener passes through the connection hole of the sensor 3 to fix the sensor 3 on the mounting bracket 2.

[0038] In some feasible ways, such as Figures 2-5 As shown, the mounting bracket 2 includes two limiting brackets 21 and two fixing brackets 22. The projections of the two limiting brackets 21 and the two fixing brackets 22 in the first direction are rectangular. The limiting brackets 21 and the fixing brackets 22 are independently set, and the two limiting brackets 21 and the two fixing brackets 22 are alternately set at the corners of the mounting bracket 2, that is, the two limiting brackets 21 are set diagonally, and the two fixing brackets 22 are also set diagonally. The supporting ribs 211 of the limiting brackets 21 have a rectangular projection in the first direction, and the bottom end of the supporting ribs 211 can be set in the gap between the air outlets 11, such as... Figure 3As shown, there are four air outlets 11 within the rectangle formed by the support ribs 211. The bottom end of the support ribs 211 completely avoids the air outlets 11. The support ribs 211 may also include an extension 215 at the top of the support ribs 211 along the first direction. The projection of the extension 215 in the first direction is V-shaped. The V-shaped openings of the extensions 215 corresponding to the two support ribs 211 are arranged opposite each other in the second direction. A first limiting rib 213 extending along the first direction is provided on each extension 215. The two first limiting ribs 213 are arranged opposite each other in the second direction. The fixing bracket 22 is constructed as a stud. Thus, when the sensor 3 is installed on the limiting bracket 21 and the fixing bracket 22, that is, the two sides of the sensor 3 in the second direction respectively abut against the two first limiting ribs 213, the two connecting holes provided on the sensor 3 are respectively aligned with the stud. Thus, the sensor 3 is fixed on the stud by passing fasteners through the connecting holes. Thus, the sensor 3 is limited in the third direction by the fasteners. In this way, the sensor 3 can be fixedly installed on the mounting bracket 2, which facilitates the detection of air.

[0039] It is understandable that the height of the support rib 211 and the height of the stud can be arranged according to the specific type of sensor 3. For example, the height of the support rib 211 and the height of the stud can be equal, or the height of the support rib 211 and the height of the stud can be unequal.

[0040] The sensor 3 can include sensors capable of measuring air quality, such as laser particle sensors, TVOC (Total Volatile Organic Compounds) sensors, and formaldehyde sensors. The specific sensor can be selected and adapted according to the operating conditions of the air conditioner. The TVOC sensor, formaldehyde sensor, or laser particle sensor mentioned in this embodiment can be existing equipment. For example, in the embodiment where the mounting bracket 2 includes two limiting brackets 21 and two fixing brackets 22, it is used to install a formaldehyde sensor or a laser particle sensor.

[0041] In some implementable embodiments, the limiting rib 212 may further include a second limiting rib 214, located above the first limiting rib 213, for limiting the sensor 3 in the first direction. For example... Figure 4 and Figure 5As shown, the mounting bracket 2 includes two limiting brackets 21 and one fixed bracket 22. The projections of the two limiting brackets 21 and the fixed bracket 22 in the second direction form a triangle, and the two limiting brackets 21 are spaced apart along the second direction. The fixed bracket 22 is located between the two limiting brackets 21 and spaced apart from the fixed bracket 22 in the third direction. Thus, the two limiting brackets 21 and the fixed bracket 22 are located at the vertices of the triangle. The fixed bracket 22 can be a stud. The limiting brackets 21 can include support ribs 211, which extend along the first direction. The bottom end of the support rib 211 avoids the air outlet 11. The support rib 211 extending along the first direction can form a lifting part to facilitate the mounting... The sensor 3 on the mounting bracket 2 forms a gap 4 with the air outlet 11. The cross-section of the support rib 211 can be V-shaped, with the V-shaped openings of the two support ribs 211 facing the stud. A first limiting rib 213 is provided at the middle of the support rib 211 in the first direction. The two first limiting ribs 213 are arranged opposite each other in the second direction, thereby limiting the two sides of the sensor 3 in the second direction. A second limiting rib 214 is provided at the top of the support rib 211 in the first direction. The second limiting rib 214 extends in the third direction, thereby limiting the top surface of the sensor 3 in the first direction. At the same time, the sensor 3 is fixed to the mounting bracket 2 by fasteners passing through the connection hole of the sensor 3. It should be noted that in the embodiment where the mounting bracket 2 includes two limiting brackets 21 and one fixed bracket 22, the corresponding sensor 3 is a TVOC sensor.

[0042] Of course, to increase the strength of the limiting bracket 21, in some feasible embodiments, the two limiting brackets 21 are connected by a connecting rib 23. The connecting rib 23 can extend along a first direction, and an auxiliary support rib 24 extending along a third direction can be provided in the middle of the connecting rib 23. The auxiliary support rib 24 cooperates with the stud to support the sensor 3. In addition, to further support the sensor 3, in some feasible embodiments, a support block 5 can be provided between the limiting bracket 21 and the fixed bracket 22. The support block 5 can provide additional support points, thereby forming a stable support for the sensor 3.

[0043] It is understandable that, in order to facilitate the installation of sensor 3, the aforementioned support rib 211, first limiting rib 213, and second limiting rib 214 are all provided with enlarged diameter sections.

[0044] To facilitate the installation of multiple sensors 3 in the air conditioner, the number of mounting brackets 2 is at least two, and the multiple mounting brackets 2 are spaced apart along the first direction. It is understood that the aforementioned mounting brackets 2 can install the same type of sensor 3, or they can install different types of sensors 3, such as... Figure 2As shown, the lower cover 1 is provided with two mounting brackets 2. One mounting bracket 2 includes two limiting brackets 21 and two fixing brackets 22, and a formaldehyde sensor is installed on this mounting bracket 2. The other mounting bracket 2 includes two limiting brackets 21 and one fixing bracket 22, and a TVOC sensor is installed on this mounting bracket 2. This allows the air conditioner to simultaneously monitor the concentration of formaldehyde and the concentration of total volatile organic compounds.

[0045] It is understood that the above-described embodiment of having two mounting brackets 2 in the air conditioner is illustrative. In other embodiments, the number of mounting brackets 2 can be set according to the specific number of sensors 3. For example, when the number of sensors 3 to be installed is three, the number of mounting brackets 2 can also be set to three. This disclosure does not specifically limit the number of mounting brackets 2.

[0046] A second aspect of this disclosure provides an air conditioner including the aforementioned filter assembly. It is understood that the air conditioner includes an indoor unit and an outdoor unit, wherein the filter assembly is installed at the return air vent of the indoor unit. The mounting bracket within the filter assembly facilitates the fixing of the sensor 3 and creates a gap with the air outlet of the lower cover 1, allowing the sensor 3 to fully contact the air, thereby improving the detection quality of the sensor 3.

[0047] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0049] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
