The embodiment of the application provides a volute component, a fresh air module and an air conditioner. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

First, an embodiment of the present application provides a volute assembly, which includes a volute case cover, a first volute and a second volute, where the second volute is located between the volute case cover and the first volute, the volute case cover and the second volute enclose to form an air inlet chamber, and the first volute and the second volute enclose to form an air outlet chamber. The volute cover is provided with a first end face and a plurality of first side faces, the first side faces form the side wall of the air inlet cavity, and one first side face is provided with an air inlet; the first volute is provided with a second end face and a plurality of second side faces, the plurality of second side faces form a side wall of the air outlet cavity, and one second side face is provided with an air outlet; the second volute comprises a partition plate, the partition plate is located between the air inlet cavity and the air outlet cavity, and a through hole is formed in the partition plate to communicate the air inlet cavity with the air outlet cavity.

As shown in fig. 2 and 3, the volute assembly 100 includes a volute cover 110, a first volute 120 and a second volute 130, the second volute 130 is located between the volute cover 110 and the first volute 120, and two sides of the second volute 130 are respectively connected with the volute cover 110 and the first volute 120.

The volute cover 110 and the second volute 130 enclose to form an air inlet cavity 113, the air inlet cavity 113 provides an air inlet duct for air circulation, and meanwhile, the air direction is guided correspondingly, so that the air is gathered in the air inlet cavity 113. The first volute casing 120 and the second volute casing 130 enclose to form an air outlet cavity 121, and the air outlet cavity 121 provides an air outlet duct for circulation of air, so that the air is collected and guided correspondingly.

As shown in fig. 4, the volute cover 110 has a first end surface 112 and a plurality of first side surfaces 111, the plurality of first side surfaces 111 form side walls of the air inlet chamber 113, and one of the first side surfaces 111 has an air inlet 1131 for communicating with outdoor air, so that the outdoor air enters the air inlet chamber 113 through the air inlet 1131 for air circulation. The position of the air inlet 1131 on the side wall of the air inlet cavity 113 can be designed and adjusted according to the installation and actual use of the scroll component 100, and it is only necessary to ensure that outdoor air can smoothly enter the air inlet cavity 113 through the air inlet 1131.

As shown in fig. 5, the first volute 120 has a second end surface 125 and a plurality of second side surfaces 124, the plurality of second side surfaces 124 form a sidewall of the air outlet cavity 121, and one of the second side surfaces 124 is provided with an air outlet 1211 for communicating with indoor air, so that outdoor air flows into the indoor space, and circulation of the indoor and outdoor air is achieved. The position of the air outlet 1211 on the sidewall of the air outlet cavity 121 can be designed and adjusted according to the installation and actual use of the volute assembly 100, and it is only necessary to ensure that outdoor air can smoothly enter the room through the air outlet 1211.

It should be noted that, in the embodiment of the present application, the air outlet cavity 121 is disposed opposite to the air inlet cavity 113, which is helpful for air to enter the air inlet cavity 113 through the air inlet 1131, flow into the air outlet cavity 121 from the air inlet cavity 113, and then flow out from the air outlet 1211, so as to avoid that the air outlet cavity 121 and the air inlet cavity 113 are greatly misaligned to cause a complicated design of a ventilation air duct, so that loss is increased when air circulates, and thus an actual air output amount is affected when air circulates.

As shown in fig. 6, the second scroll 130 includes a partition 131, the partition 131 is located between the air inlet chamber 113 and the air outlet chamber 121, and a through hole 135 is formed on the partition 131 to communicate the air inlet chamber 113 and the air outlet chamber 121. On one hand, the second volute 130 separates the air inlet cavity 113 from the air outlet cavity 121, so that the disturbance caused by the crosstalk of outdoor air and indoor air is avoided; on the other hand, the second volute 130 communicates the air inlet cavity 113 and the air outlet cavity 121, and the air is guided through the through hole 135, so that the air flow rate can be changed, and the air outlet effect is improved.

The second volute 130 can be separately connected with the first volute 120 and the volute cover 110, or the second volute 130 can be connected with the volute cover 110 first and then connected with the first volute 120; alternatively, the second volute 130 and the volute cover 110 are integrally formed and then integrally connected to the first volute 120. The concrete connection mode can be adjusted according to actual design requirements, and the stability of the overall structure of the volute component is guaranteed.

The volute assembly 100 in the embodiment of the present application includes a volute cover 110, a first volute 120 and a second volute 130, the volute cover 110 and the second volute 130 enclose to form an air inlet chamber 113, the first volute 120 and the second volute 130 enclose to form an air outlet chamber 121, and a partition plate 131 of the second volute 130 is located between the air inlet chamber 113 and the air outlet chamber 121 and is provided with a through hole 135 to communicate the air inlet chamber 113 and the air outlet chamber 121. The worm case cover 110 is provided with a first end face 112 and a plurality of first side faces 111, and the plurality of first side faces 111 form the side walls of the air inlet cavity 113, so that the air inlet cavity 113 is arranged on the worm case cover 110; the first volute 120 has a second end surface 125 and a plurality of second side surfaces 124, and the plurality of second side surfaces 124 form a sidewall of the air outlet chamber 121, so that the air outlet chamber 121 is disposed on the first volute. This kind of structural design can guarantee the integrality of air inlet chamber 113 and air-out chamber 121, compares in traditional structure with air inlet chamber 113 and air-out chamber 121 split on different parts, can avoid air inlet chamber 113 and air-out chamber 121 lateral wall to receive the fluid impact for a long time and lead to the leakproofness variation to reduce spiral case subassembly 100 and take place the risk of leaking out.

Optionally, a notch is formed in one side of the air outlet 1211 close to the partition plate 131, and an edge of the notch abuts against a surface of the partition plate 131 facing the air outlet cavity 121. That is, the air outlet 1211 on the sidewall of the air outlet cavity 121 is not a complete closed opening, but a notch is formed on one side, the shape of the notch is similar to a "U", and the edge of the notch abuts against the surface of the partition 131 to form a complete air outlet 1211. The structure design is beneficial to the formation of the air outlet 1211 on the air outlet cavity 121, and is convenient for the positioning of the air outlet 1211.

It should be noted that the air outlet 1211 can be completely opened on the side wall of the air outlet cavity 121, that is, an opening is dug from the side wall of the air outlet cavity 121, and the periphery of the opening is surrounded by the side wall of the air outlet cavity 121, such a design manner makes the opening position of the air outlet 1211 more flexible, and is not limited by the connection manner of the first spiral case 120 and the second spiral case 130, and the structural design of the second spiral case 130 does not need to consider the matching with the air outlet 1211, so that the overall structural design of the spiral case assembly 100 is more diverse, and different structural design requirements are met.

Optionally, one side of the air outlet cavity 121 facing the second volute 130 is provided with a first opening 1212, and an edge of the first opening 1212 abuts against a surface of the partition plate 131 facing the air outlet cavity 121, that is, in the use process of the volute assembly 100, the edge of the first opening 1212 abuts against a surface of the partition plate 131 facing the air outlet cavity 121 to form a closed air outlet cavity 121.

The edge of the first opening 1212 abuts against the surface of the partition 131, so that the joint of the first volute 120 and the second volute 130 is the edge of the first opening 1212, and when the volute assembly 100 is disassembled, the first volute 120 and the second volute 130 are divided into two parts from the abutting position, namely, the weak area of the air outlet chamber 121 is located at the edge of the first opening 1212 of the air outlet chamber 121.

It should be noted that, during the use of the volute assembly 100, the area most strongly impacted by the air fluid is the middle area of the air outlet chamber 121, and in the conventional structure, the air outlet chamber 121 is divided into two parts from the middle area and respectively disposed on the first volute 120 and the second volute 130, that is, the connection point of the first volute 120 and the second volute 130 is the middle area of the air outlet chamber 121.

Because the first volute casing 120 and the second volute casing 130 have an assembly gap and the machining size precision of the parts per se fluctuates, the assembly effect of the first volute casing 120 and the second volute casing 130 can be affected, and in the operation process of the volute casing assembly 100, the joint of the first volute casing 120 and the second volute casing 130 can be impacted by long-term air fluid, so that the hidden air leakage problem is caused, and higher strength requirements are needed for corresponding parts.

In the embodiment of the present application, the connection portion of the first volute 120 and the second volute 130 is disposed at the edge of the first opening 1212, and compared with the conventional structure, the structural design makes the connection portion of the first volute 120 and the second volute 130 have a smaller impact effect on the air fluid, so that the sealing performance is not easily reduced due to the deformation caused by long-term use, and the air leakage of the volute assembly 100 in the use process can be effectively prevented, thereby ensuring the structural stability of the volute assembly 100, and increasing the air volume of the volute assembly 100 compared with the conventional structure.

Optionally, the edge of the first opening 1212 is provided with a first limiting portion 122, a first limiting groove 132 is formed in a position of the second volute 130 corresponding to the first limiting portion 122, and the first limiting portion 122 is embedded in the first limiting groove 132 to connect the first volute 120 and the second volute 130. Through the mutual matching of the first limiting part 122 and the first limiting groove 132, the sealing performance of the joint of the first volute 120 and the second volute 130 can be enhanced, the risk of air leakage at the joint of the first volute 120 and the second volute 130 is further reduced, and the structural stability of the volute assembly 100 is ensured.

When the first volute casing 120 and the second volute casing 130 are installed, the first limiting portion 122 on the first volute casing 120 is aligned with the first limiting groove 132 on the second volute casing 130, and the first limiting portion 122 is embedded into the first limiting groove 132, so that the first volute casing 120 and the second volute casing 130 can be clamped, meanwhile, the sealing performance of the joint can be enhanced due to the staggered connection of the first limiting portion 122 and the first limiting groove 132, and the situation that air fluid flows out from the joint of the first volute casing 120 and the second volute casing 130 in the use process of the volute casing assembly 100 is avoided, and the air output of the volute casing assembly 100 is reduced.

Optionally, the clamping connection manner between the first scroll casing 120 and the second scroll casing 130 can be changed, that is, the edge of the first opening 1212 is provided with a second limiting groove, the second scroll casing 130 is provided with a second limiting portion corresponding to the second limiting groove, and the second limiting portion is embedded in the second limiting groove to connect the first scroll casing 120 and the second scroll casing 130. Through the mutual matching of the second limiting part and the second limiting groove, the sealing performance of the joint of the first volute casing 120 and the second volute casing 130 can be enhanced, and the risk of air leakage at the joint of the first volute casing 120 and the second volute casing 130 is reduced.

Similarly, when the first volute 120 and the second volute 130 are installed, the second limiting portion is embedded into the second limiting groove, so that the first volute 120 and the second volute 130 are clamped, meanwhile, the sealing performance of the joint of the first volute 120 and the second volute 130 is enhanced, and the air volume of the volute assembly 100 in the use process is ensured.

Optionally, to further enhance the sealing performance at the joint between the first volute 120 and the second volute 130, when the structures of the first volute 120 and the second volute 130 are designed, the edge of the first opening 1212 of the first volute 120 is simultaneously provided with the first limiting portion 122 and the second limiting groove, the position of the second volute 130 corresponding to the first limiting portion 122 is provided with the first limiting groove 132, and the position of the second volute 130 corresponding to the second limiting groove is provided with the second limiting portion, that is, a double-clamping structure is designed between the first volute 120 and the second volute 130, so as to ensure the sealing performance at the joint between the first volute 120 and the second volute 130.

When the first scroll casing 120 and the second scroll casing 130 are assembled, the first limiting portion 122 needs to be embedded into the first limiting groove 132, and the second limiting portion needs to be embedded into the second limiting groove. When there is a gap between the first position-limiting portion 122 and the first position-limiting groove 132 due to the matching accuracy, the second position-limiting portion and the second position-limiting groove can play a second layer of protection to ensure the sealing performance between the first scroll casing 120 and the second scroll casing 130.

In addition, because the first limiting part 122 and the first limiting groove 132 as well as the second limiting part and the limiting groove are in staggered clamping connection, the risk of dislocation and deformation at the joint of the first volute 120 and the second volute 130 can be reduced in the process that the air fluid impacts the air outlet cavity 121 for a long time.

Optionally, the scroll casing assembly 100 further includes a connecting member, a first fixing column 123 is disposed at an edge of the first scroll casing 120 close to the second scroll casing 130, a first fixing hole is formed in the first fixing column 123, a second fixing column 133 is disposed at a position of the edge of the second scroll casing 130 close to the first scroll casing 120, which corresponds to the first fixing column 123, a second fixing hole is formed in a position of the second fixing column 133, which corresponds to the first fixing hole, and the connecting member passes through the first fixing hole and is inserted into the second fixing hole, so as to fixedly connect the first scroll casing 120 and the second scroll casing 130.

The connecting pieces are bolts, threads are arranged in the first fixing hole and the second fixing hole, and when the first volute 120 and the second volute 130 need to be detached, the bolts are reversely screwed out of the first fixing hole and the second fixing hole, so that the first volute 120 and the second volute 130 can be detached and replaced at any time.

It should be noted that, the bolt fixing structure is added between the first scroll casing 120 and the second scroll casing 130, so that it can be prevented that the first limiting portion 122 and the first limiting groove 132 or the second limiting portion and the second limiting groove are separated from each other due to collision or structural aging deformation and the like in the long-term use process of the scroll casing assembly 100, which leads to loose connection between the first scroll casing 120 and the second scroll casing 130 and air leakage, and thus affects the normal use of the scroll casing assembly 100.

Optionally, the side of the intake plenum 113 facing the second volute 130 has a second opening 1132. The edge of the second opening 1132 is provided with a third limiting part 114, a third limiting groove is formed in the position of the second volute 130 corresponding to the third limiting part 114, and the third limiting part 114 is embedded in the third limiting groove to connect the volute cover 110 and the second volute 130. The third limiting part 114 is matched with the third limiting groove, so that the sealing performance of the joint of the volute cover 110 and the second volute 130 can be enhanced, the risk of air leakage at the joint of the volute cover 110 and the second volute 130 is reduced, and the air inlet volume of the volute component 100 is ensured.

When the volute cover 110 and the second volute 130 are installed, the third limiting portion 114 on the volute cover 110 is only required to be aligned to the third limiting groove on the second volute 130, and the third limiting portion 114 is embedded into the third limiting groove, so that the volute cover 110 and the second volute 130 can be clamped, meanwhile, the sealing performance of the joint can be enhanced through the staggered connection of the third limiting portion 114 and the third limiting groove, and the situation that air fluid flows out from the joint of the volute cover 110 and the second volute 130 in the use process of the volute component 100 is avoided, and the air inlet volume of the volute component 100 is reduced.

Optionally, the clamping connection between the volute cover 110 and the second volute 130 can be changed, that is, the edge of the second opening 1132 is provided with a fourth limiting groove, a fourth limiting portion is arranged at a position of the second volute 130 corresponding to the fourth limiting groove, and the fourth limiting portion is embedded in the fourth limiting groove to connect the volute cover 110 and the second volute 130. Through the mutual matching of the fourth limiting part and the fourth limiting groove, the sealing performance of the joint of the volute cover 110 and the second volute 130 can be enhanced, and the risk of air leakage at the joint of the volute cover 110 and the second volute 130 is reduced.

Similarly, when the volute cover 110 and the second volute 130 are installed, the fourth limiting part is embedded into the fourth limiting groove, so that the volute cover 110 is clamped with the second volute 130, the sealing performance of the joint of the volute cover 110 and the second volute 130 is enhanced, and the air inlet amount of the volute assembly 100 in the use process is ensured.

Optionally, in order to further enhance the sealing performance at the joint between the scroll casing cover 110 and the second scroll casing 130, when the structures of the scroll casing cover 110 and the second scroll casing 130 are designed, the edge of the second opening 1132 of the scroll casing cover 110 is simultaneously provided with a third limiting portion 114 and a fourth limiting groove, the third limiting groove is formed at the position of the second scroll casing 130 corresponding to the third limiting portion 114, and the fourth limiting portion is formed at the position of the second scroll casing 130 corresponding to the fourth limiting groove, that is, a dual clamping structure is designed between the scroll casing cover 110 and the second scroll casing 130, so as to ensure the sealing performance at the joint between the scroll casing cover 110 and the second scroll casing 130.

When the casing cover 110 and the second scroll casing 130 are assembled, the third position-limiting portion 114 needs to be embedded into the third position-limiting groove, and the fourth position-limiting portion needs to be embedded into the fourth position-limiting groove.
