Detailed Description

The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

An air duct assembly 100 of an air conditioner 1000 according to an embodiment of the present invention will be described with reference to fig. 1 to 9.

As shown in fig. 1 to 5, in the air duct assembly 100 of the air conditioner 1000 according to the present invention, the air duct assembly 100 includes an inlet volute 110 and a temperature and/or humidity sensor 120.

Specifically, as shown in fig. 1 and 3, the inlet volute 110 may define an inlet duct 111. The air intake duct 111 is adapted to guide the external air flow into the air conditioner 1000. The temperature and/or humidity sensor 120 is disposed in the intake air duct 111, and the temperature and/or humidity sensor 120 may be connected to the intake volute 110. Therefore, by arranging the temperature and/or humidity sensor 120 in the intake air duct 111, the temperature and/or humidity of the air flow in the intake air duct 111 can be detected by the temperature and/or humidity sensor 120, and the intake state of the air conditioner 1000 can be adjusted (for example, the intake air amount can be changed) according to the detection information of the temperature and/or humidity sensor 120, so that the probability of the occurrence of condensed water in the intake volute 110 can be reduced.

For example, as shown in fig. 1-4, the inlet volute 110 defines a receiving cavity, the receiving cavity may be used as an inlet duct 111 of the air conditioner 1000, an inlet 113 is configured at a right end of the inlet volute 110, and the inlet 113 is communicated with the inlet duct 111 to guide the outside air flow into the inlet duct 111. The temperature and/or humidity sensor 120 is disposed in the intake air duct 111, and the temperature and/or humidity sensor 120 is connected to an inner top plate of the intake volute 110.

According to the air duct assembly 100 of the air conditioner 1000 in the embodiment of the invention, by arranging the temperature and/or humidity sensor 120 in the intake air duct 111, the temperature and/or humidity of the air flow in the intake air duct 111 can be detected by the temperature and/or humidity sensor 120, and the intake state of the air conditioner 1000 can be adjusted (for example, the intake air amount is changed) according to the detection information of the temperature and/or humidity sensor 120, so that the probability of the occurrence of condensed water in the intake volute 110 is reduced.

As shown in fig. 4 and 5, according to some embodiments of the present invention, one of the temperature and/or humidity sensor 120 and the inlet volute 110 may have a catching protrusion 112, and the other may have a catching groove 121 adapted to the catching protrusion 112. Therefore, the clamping protrusions 112 and the clamping grooves 121 which can be matched are arranged on the temperature and/or humidity sensor 120 and the air inlet volute 110, so that the connection tightness between the temperature and/or humidity sensor 120 and the air inlet volute 110 can be improved, the connection mode between the temperature and/or humidity sensor 120 and the air inlet volute 110 can be simplified, the dismounting operation of the temperature and/or humidity sensor 120 is simplified, and the dismounting efficiency of the temperature and/or humidity sensor 120 is improved.

For example, as shown in fig. 4, a clamping groove 121 is formed on the temperature and/or humidity sensor 120, a clamping protrusion 112 is formed on the inner side top plate of the inlet volute 110 corresponding to the clamping groove 121, the clamping groove 121 is adapted to be connected with the clamping protrusion 112 in a matching manner, and the temperature and/or humidity sensor 120 is already installed on the inner side top plate of the inlet volute 110.

As shown in fig. 6, according to some embodiments of the present invention, the temperature and/or humidity sensor 120 may include a connection portion 122 and a sensing member 123, one end of the connection portion 122 may be connected to the sensing member 123, and the other end may be provided with a catching groove 121. Therefore, the connecting part of the temperature and/or humidity sensor 120 and the air inlet volute 110 can be intensively arranged on the connecting part 122, so that the probability of interference between the matching part of the clamping protrusion 112 and the clamping groove 121 and the sensing assembly 123 can be reduced, and the reliability of the temperature and/or humidity sensor 120 can be improved.

For example, as shown in fig. 5 and 6, one connecting portion 122 is connected to each of the left and right sides of the sensing element 123, the two connecting portions 122 are spaced apart from each other, and the two connecting portions 122 are located above the sensing element 123. The lower end of the connecting portion 122 located on the left side is connected to the left side of the upper end surface of the sensing element 123, the upper end portion of the connecting portion 122 is configured with a catching groove 121, the lower end of the connecting portion 122 located on the right side is connected to the right side of the upper end surface of the sensing element 123, and the upper end portion of the connecting portion 122 is also configured with a catching groove 121.

As shown in fig. 5 to 7, according to some embodiments of the present invention, the chucking grooves 121 may be plural, and the plurality of chucking grooves 121 may be spaced apart in a circumferential direction of the temperature and/or humidity sensor 120. Therefore, the clamping grooves 121 can be uniformly distributed on the periphery of the temperature and/or humidity sensor 120, so that the probability that the part of the temperature and/or humidity sensor 120 is not tightly connected with the air inlet volute 110 due to the fact that the clamping grooves 121 are not uniformly distributed can be reduced, and the installation reliability of the temperature and/or humidity sensor 120 can be improved.

As shown in fig. 5 to 7, there may be a plurality of clamping protrusions 112, and the plurality of clamping protrusions 112 and the plurality of clamping grooves 121 may correspond to each other one by one. That is, when one of the clamping protrusions 112 is adapted to the corresponding clamping groove 121, the rest clamping protrusions 112 are correspondingly connected to the clamping grooves 121. From this, through setting up protruding 112 of joint of reasonable quantity, and an arbitrary joint is protruding 112 all corresponds with a joint groove 121 and is connected, both can improve the steadiness that temperature and/or humidity transducer 120 and air inlet spiral case 110 are connected to improve the reliability of temperature and/or humidity transducer 120 assembly, can optimize the protruding 112 of joint, the overall arrangement in joint groove 121 again, save the cost. For example, the plurality of clamping protrusions 112 may form a plurality of sets of clamping fits with the plurality of clamping grooves 121, and when any clamping fit in the plurality of sets of clamping fits fails, the rest clamping fits may still connect and fasten the temperature and/or humidity sensor 120 with the inlet volute 110.

For example, as shown in fig. 6, the upper end portion of the left side connecting portion 122 is configured with two catching grooves 121, the upper end portion of the right side connecting portion 122 is also configured with two catching grooves 121, and the four catching grooves 121 are spaced apart in the circumferential direction of the temperature and/or humidity sensor 120. Two clamping protrusions 112 are formed at the positions of the two clamping grooves 121 corresponding to the left connecting portion 122 on the inner top plate of the air inlet volute 110 shown in fig. 5 and 7, and two clamping protrusions 112 are also formed at the positions of the two clamping grooves 121 corresponding to the right connecting portion 122.

As shown in fig. 6, according to some embodiments of the present invention, the catching groove 121 may have an open opening, and an inner sidewall of the catching groove 121 at the open opening is an inclined surface. From this, when joint arch 112 is connected with the cooperation of joint groove 121, the inclined plane is suitable for guide joint arch 112 to slide towards joint groove 121 to can reduce joint arch 112 and the complex operation degree of difficulty of joint groove 121, with the efficiency that improves joint arch 112 and joint groove 121 cooperation and be connected, and then can improve temperature and/or humidity transducer 120's assembly efficiency.

As shown in fig. 6, according to some embodiments of the present invention, the connection portion 122 may have a gap 1221, and the gap 1221 is spaced apart from the catching groove 121. From this, through setting up the breach 1221 that sets up with joint groove 121 interval, when joint arch 112 and joint groove 121 adaptation are connected, breach 1221 can dodge the space for the inside wall in joint groove 121 provides to make joint arch 112 can stretch into joint groove 121, in order to accomplish the joint cooperation.

For example, as shown in fig. 6, a gap 1221 is formed between two clip grooves 121 on the left connecting portion 122, and a gap 1221 is also formed between two clip grooves 121 on the right connecting portion 122. It should be noted that, when the temperature and/or humidity sensor 120 is connected to the inlet volute 110, the clamping protrusion 112 is adapted to fit with the clamping groove 121, and in this process, the clamping protrusion 112 can slide toward the inside of the clamping groove 121 along the inner sidewall of the corresponding clamping groove 121.

At this moment, protruding 112 of joint can exert pressure to the inside wall in joint groove 121, and breach 1221 can provide the deformation space for the inside wall in joint groove 121 to make the open mouth in joint groove 121 enlarge, thereby can make protruding 112 of joint can relatively easily slide in to the inside in joint groove 121 and accomplish the joint cooperation.

As shown in fig. 8 and 9, the air duct assembly 100 of the air conditioner 1000 may further include an electronic control module and a line card 130 according to some embodiments of the present invention. Wherein, the electronic control module can be electrically connected with the temperature and/or humidity sensor 120 through a wire 131. It should be noted that the electronic control module can be used as a power supply structure of the temperature and/or humidity sensor 120 to supply power to the temperature and/or humidity sensor 120, and can be used as a regulation structure of the temperature and/or humidity sensor 120 to control the operating state of the temperature and/or humidity sensor 120.

As shown in fig. 8 and 9, the line card 130 may be disposed in the inlet volute 110, and the wire 131 may be disposed through the line card 130. Therefore, by arranging the line card 130 through which the wire 131 can penetrate on the air inlet volute 110, the wire 131 can be fixed by using the line card 130 to form a specific wiring layout, so that the probability of interference between the wire 131 and other components caused by free wiring of the wire 131 (the "free wiring" here can be understood as a wiring mode in which the wire 131 is not bound and is freely distributed) is reduced, and the reliability and safety of the electrical connection between the temperature and/or humidity sensor 120 and the electronic control module are improved.

As shown in fig. 8 and 9, according to some embodiments of the invention, the line card 130 may be located below the temperature and/or humidity sensor 120 such that the wire 131 forms a return bend 1311 (where "return bend 1311" is a portion of the wire 131). Thus, by disposing the line card 130 below the temperature and/or humidity sensor 120 to configure the lead 131 as the return bend 1311, the probability that the condensed water on the lead 131 flows into the temperature and/or humidity sensor 120 along the lead 131 can be reduced, thereby improving the reliability of the temperature and/or humidity sensor 120.

For example, return bend 1311 may be an S-shaped or U-shaped wire segment. As shown in fig. 9, a line card 130 is disposed on an inner sidewall of the inlet volute 110, and the line card 130 is located below the temperature and/or humidity sensor 120. The right end of the temperature and/or humidity sensor 120 has an electrical connection end, the wire 131 is connected to the electrical connection end, and the wire 131 extends toward the line card 130 to form a top-down wiring manner, and after the wire 131 passes through the line card 130, the wire 131 passing through the line card 130 is wired upward to be connected to the electronic control module. At this point, the wire 131 may form a U-shaped return bend 1311 at the line card 130. It will be appreciated that when condensation occurs on the wire 131, the condensation may collect along the wire 131 towards the return bend 1311 under the force of the gravity of the condensation itself.

As shown in fig. 9, according to some embodiments of the present invention, the air duct assembly 100 of the air conditioner 1000 may include a reinforcing rib 140, and the reinforcing rib 140 may be connected between the line card 130 and the inlet volute 110. Therefore, by arranging the reinforcing ribs 140 between the line card 130 and the air inlet volute 110, the reinforcing ribs 140 can be used as a connecting structure between the line card 130 and the air inlet volute 110 to improve the tightness of the connection between the line card 130 and the air inlet volute 110, and the reinforcing ribs 140 can be used as a supporting structure of the line card 130 to improve the structural strength of the line card 130, thereby improving the reliability of the line card 130.

It should be noted that, when the wire 131 is inserted into the line card 130, the line card 130 may perform a limiting and fixing function on the wire 131, so that by enhancing the structural strength of the line card 130, the probability of deviation of the wire 131 caused by damage to the line card 130 may be reduced, and thus, the reliability and safety of the electrical connection between the temperature and/or humidity sensor 120 and the electronic control module may be improved.

For example, as shown in fig. 9, the upper end of the line card 130 is provided with a reinforcing rib 140, one end of the reinforcing rib 140 is connected to the inlet volute 110, the other end of the reinforcing rib 140 extends toward the inside of the inlet volute 110, and the lower end surface of the reinforcing rib 140 is connected to the upper end surface of the line card 130.

As shown in fig. 8, there may be multiple line cards 130 according to some embodiments of the invention. Therefore, the limiting and fixing capacity of the line cards 130 to the wires 131 can be improved by arranging a reasonable number of the line cards 130, so that the reliability of wiring of the wires 131 is improved, the layout of the line cards 130 can be optimized, and the cost is saved.

Further, at least one of the plurality of line cards 130 is disposed on an inner sidewall of the inlet volute 110. It should be noted that the temperature and/or humidity sensor 120 is disposed on the inner sidewall of the inlet volute 110, and the wire 131 between the temperature and/or humidity sensor 120 and the electronic control module at least partially penetrates through the inner side of the inlet volute 110. Therefore, by arranging at least one line card 130 on the inner side wall of the air inlet volute 110, the partial conducting wire 131 penetrating the inner side of the air inlet volute 110 can be limited and fixed, so that the safety and reliability of routing of the conducting wire 131 inside the air inlet volute 110 are improved.

In addition, the line card 130 provided at the inner sidewall of the inlet volute 110 may form a return bend 1311 to reduce the probability that the condensed water on the wire 131 flows along the wire 131 into the temperature and/or humidity sensor 120.

For example, as shown in fig. 8, two line cards 130 are provided on the inner sidewall of the inlet volute 110. One line card 130 is located below the temperature and/or humidity sensor 120, another line card 130 is located at the upper edge of the inner sidewall of the inlet volute 110, and one line card 130 is located on the outer wall of the inlet volute 110.

It should be noted that the specific routing manner of the electrical connection between the temperature and/or humidity sensor 120 and the electronic control module is as follows:

the wires 131 connected to the temperature and/or humidity sensor 120 extend from top to bottom towards the line card 130 located below the temperature and/or humidity sensor 120, after the wires 131 pass through the line card 130, the wires 131 may extend upwards and sequentially pass through the line card 130 at the upper edge of the inner side wall of the inlet volute 110 and the line card 130 on the outer wall of the inlet volute 110, and then the wires 131 may extend towards the electronic control module to form an integral routing manner of the wires 131.

As shown in fig. 9, in some embodiments, the line card 130 may be a resilient arm. Therefore, the line card 130 is arranged to be the elastic arm, the line card 130 can be controlled to be opened or buckled by changing the deformation state of the elastic arm, so that the wire 131 is convenient to break away from the limit of the line card 130 when the wire 131 needs to be maintained or the wiring layout is changed, and the dismounting efficiency of the wire 131 can be improved.

The air conditioner 1000 according to an embodiment of the present invention includes the air duct assembly 100 of the air conditioner 1000.

According to the air conditioner 1000 of the embodiment of the invention, the temperature and/or humidity sensor 120 is arranged in the air inlet duct 111, so that the temperature and/or humidity of the air flow in the air inlet duct 111 can be detected by the temperature and/or humidity sensor 120, and the air inlet state of the air conditioner 1000 can be adjusted (for example, the air inlet amount is changed) according to the detection information of the temperature and/or humidity sensor 120, thereby reducing the probability of the condensed water of the air inlet volute 110.

Therefore, the connection mode of the temperature and/or humidity sensor 120 and the air inlet volute 110 can be simplified, so that the dismounting operation of the temperature and/or humidity sensor 120 is simplified, and the dismounting efficiency of the temperature and/or humidity sensor 120 is improved.

As shown in fig. 5 and 6, the temperature and/or humidity sensor 120 includes a sensing assembly 123 and a connecting portion 122, the sensing assembly 123 has one connecting portion 122 connected to each of the left and right sides thereof, the two connecting portions 122 are spaced apart from each other, and the two connecting portions 122 are located above the sensing assembly 123. The lower end of the connecting portion 122 located on the left side is connected to the left side of the upper end surface of the sensing element 123, the upper end portion of the connecting portion 122 is configured with a catching groove 121, the lower end of the connecting portion 122 located on the right side is connected to the right side of the upper end surface of the sensing element 123, and the upper end portion of the connecting portion 122 is also configured with a catching groove 121.

Therefore, the connecting part 122 between the temperature and/or humidity sensor 120 and the air inlet volute 110 can be intensively arranged on the connecting part 122, so that the probability of interference between the matching part of the clamping protrusion 112 and the clamping groove 121 and the sensing assembly 123 can be reduced, and the reliability of the temperature and/or humidity sensor 120 can be improved.

As shown in fig. 6, the upper end portion of the left side connecting portion 122 is configured with two catching grooves 121, the upper end portion of the right side connecting portion 122 is also configured with two catching grooves 121, and the four catching grooves 121 are spaced apart in the circumferential direction of the temperature and/or humidity sensor 120. Two clamping protrusions 112 are formed at the positions of the two clamping grooves 121 corresponding to the left connecting portion 122 on the inner top plate of the air inlet volute 110 shown in fig. 5 and 7, and two clamping protrusions 112 are also formed at the positions of the two clamping grooves 121 corresponding to the right connecting portion 122. And the plurality of catching protrusions 112 may be fitted with the plurality of catching grooves 121 in a one-to-one correspondence, whereby the reliability of the assembly of the temperature and/or humidity sensor 120 may be improved.

As shown in fig. 6, the catching groove 121 has an opening facing upward, and an inner sidewall of the opening of the catching groove 121 is an inclined surface. From this, when joint arch 112 is connected with the cooperation of joint groove 121, the inclined plane is suitable for guide joint arch 112 to slide towards joint groove 121 to can reduce joint arch 112 and the complex operation degree of difficulty of joint groove 121, with the efficiency that joint arch 112 and joint groove 121 cooperation are connected is improved, and then can improve temperature and/or humidity transducer 120's assembly efficiency.

As shown in fig. 6, a gap 1221 is formed between the two catching grooves 121 of the left connecting portion 122, and a gap 1221 is also formed between the two catching grooves 121 of the right connecting portion 122. It should be noted that, when the temperature and/or humidity sensor 120 is connected to the inlet volute 110, the clamping protrusion 112 is adapted to fit with the clamping groove 121, and in this process, the clamping protrusion 112 can slide toward the inside of the clamping groove 121 along the inner sidewall of the corresponding clamping groove 121. At this moment, protruding 112 of joint can exert pressure to the inside wall in joint groove 121, and breach 1221 can provide the deformation space for the inside wall in joint groove 121 to make the open mouth in joint groove 121 enlarge, thereby can make protruding 112 of joint can relatively easily slide in to the inside in joint groove 121 and accomplish the joint cooperation.

As shown in fig. 8 and 9, a line card 130 is disposed on the inlet volute 110, and the wire 131 may be inserted through the line card 130. Therefore, the wire card 130 through which the wire 131 can pass is arranged on the air inlet volute 110, and the wire 131 can be fixed by the wire card 130 to form a specific circuit layout, so that the reliability and the safety of the electric connection between the temperature and/or humidity sensor 120 and the electronic control module can be improved.

As shown in fig. 8 and 9, two line cards 130 are provided on the inner sidewall of the inlet volute 110. One line card 130 is located below the temperature and/or humidity sensor 120, another line card 130 is located at the upper edge of the inner sidewall of the inlet volute 110, and one line card 130 is located on the outer wall of the inlet volute 110.

The right end of the temperature and/or humidity sensor 120 has an electrical connection end, the wire 131 is connected to the electrical connection end, and the wire 131 extends toward the wire card 130 located below the temperature and/or humidity sensor 120 to form a top-down routing manner, and after the wire 131 passes through the wire card 130, the wire 131 passing through the wire card 130 passes upward and sequentially passes through the wire card 130 at the upper edge of the inner side wall of the air inlet volute 110 and the wire card 130 on the outer wall of the air inlet volute 110. At this time, the wire 131 may form an arc-shaped return bend 1311 at the line card 130 located below the temperature and/or humidity sensor 120. Thereby, the condensed water on the wire 131 can be prevented from flowing into the inside of the temperature and/or humidity sensor 120.

As shown in fig. 9, the upper end of the line card 130 is provided with a reinforcing rib 140, one end of the reinforcing rib 140 is connected to the inlet volute 110, the other end of the reinforcing rib 140 extends toward the inside of the inlet volute 110, and the lower end surface of the reinforcing rib 140 is connected to the upper end surface of the line card 130. Thereby, the structural strength of the line card 130 may be improved, thereby improving the reliability of the line card 130.
