Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a fresh air module and an air conditioner. Background Art

[0002] Currently, air conditioners are appliances that regulate indoor temperature and humidity. Fresh air air conditioners are those that incorporate a fresh air module to draw outdoor air into the room. Fresh air air conditioners have a fan in the indoor unit that draws outdoor air directly into the room. However, due to the wide temperature difference between the outdoor and indoor temperatures, direct airflow to the outside air can lead to poor user experience.

[0003] In the related art, there is a fresh air air conditioner with an independent fresh air chamber inside the indoor unit. The fresh air chamber can simultaneously draw in indoor air and outdoor air, mixing the outdoor air with the indoor air before sending it indoors. The mixed air has a relatively small temperature difference with the indoor air, which provides a relatively good user experience.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The air supply mode is relatively simple and it is difficult to meet the different air supply needs of users.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0035] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure.

[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] Combine Figure 1-6 As shown, the embodiment of the present disclosure provides a fresh air module, comprising: a connecting box 100, a shielding portion 200, a first baffle 310 and a second baffle 320. The connecting box 100 is provided with an internal circulation air inlet 101, a fresh air inlet 102 and an air outlet 103; the shielding portion 200 is rotatably arranged in the connecting box 100, and can close the internal circulation air inlet 101; the first baffle 310 is connected to the shielding portion 200, and can close the fresh air inlet 102; the second baffle 320 is connected to the shielding portion 200, and is located on the same side of the shielding portion 200 as the first baffle 310, and can close the fresh air inlet 102; wherein, when the shielding portion 200 is rotated to the first position, the shielding portion 310 is located on the same side of the shielding portion 20 ... The blocking portion 200 closes the internal circulation air inlet 101, and the first baffle 310 closes the fresh air inlet 102; when the blocking portion 200 is rotated to the second position, the blocking portion 200 closes the internal circulation air inlet 101, and the fresh air inlet 102 is opened; when the blocking portion 200 is rotated to the third position, the second baffle 320 closes the fresh air inlet 102, and the internal circulation air inlet 101 is opened; when the blocking portion 200 is rotated to the fourth position, both the fresh air inlet 102 and the internal circulation air inlet 101 are opened.

[0042] By adopting the fresh air module provided by the embodiment of the present disclosure, the shielding part 200 rotates to the first position, which can close the internal circulation air inlet 101 and the fresh air inlet 102. The shielding part 200 rotates to the second position, which can close the internal circulation air inlet 101 and open the fresh air inlet 102 to realize the fresh air mode. The shielding part 200 rotates to the third position, which can close the fresh air inlet 102 and open the internal circulation air inlet 101 to realize the indoor internal circulation mode. The shielding part 200 rotates to the fourth position, which can open both the fresh air inlet 102 and the internal circulation air inlet 101 to realize the mixed air mode. In addition, a variety of air supply modes can be realized to meet the different air supply needs of users. And only the shielding part 200 needs to be controlled to rotate, and the number of components to be controlled is relatively small, which reduces the risk of failure during long-term operation.

[0043] As will be appreciated, as the shielding portion 200 moves from the first position to the third position, the fresh air inlet 102 and the internal circulation inlet 101 are simultaneously opened. Furthermore, the air volume of the fresh air inlet 102 and the internal circulation inlet 101 are dynamically adjusted, thereby changing the mixed air ratio. In the event of a large temperature difference between indoor and outdoor, the air volume of the fresh air inlet 102 can be reduced accordingly to reduce the risk of a significant drop in indoor temperature over a short period of time.

[0044] Combine Figure 7 As shown, specifically, a gap is provided between the first baffle 310 and the second baffle 320. Thus, as the shielding portion 200 moves from the first position to the third position, the first baffle 310 gradually moves away from the fresh air inlet 102, while the second baffle 320 moves toward the fresh air inlet 102. The fresh air inlet 102 can draw air into the communication box 100 through the gap between the first baffle 310 and the second baffle 320, ensuring the air mixing effect of the air mixing mode.

[0045] Combine Figure 8 As shown, the shielding portion 200 optionally includes a rotating ring 210 and a rotating plate 220. The first baffle 310 and the second baffle 320 of the rotating ring 210 are connected to the rotating ring 210, and the rotating ring 210 is rotatably disposed within the communication box 100. The rotating plate 220 is disposed inside the rotating ring 210 and connected to the rotating ring 210. The rotating plate 220 is rotatably disposed within the communication box 100, capable of closing the internal circulation air inlet 101. In this way, the rotating plate 220 and the rotating ring 210 rotate within the communication box 100, and the rotating ring 210 drives the first baffle 310 and the second baffle 320 to move, thereby controlling the opening or closing of the fresh air inlet 102 and the opening or closing of the internal circulation air inlet 101. This enables multiple air supply modes to meet the user's different air supply needs. Furthermore, only the rotation of the rotating ring 210 needs to be controlled, and relatively few components need to be controlled, reducing the risk of failure during long-term operation.

[0046] It is understood that when the shielding portion 200 moves to the first position, the rotating plate 220 and the rotating ring 210 rotate to the first position. Similarly, when the shielding portion 200 moves to the second, third, and fourth positions, the rotating plate 220 and the rotating ring 210 rotate to the second, third, and fourth positions, respectively.

[0047] Optionally, the rotating plate 220 and the rotating ring 210 are both in sliding contact with the inner side wall of the connecting box 100 where the internal circulation air inlet 101 is opened. In this way, the rotating plate 220 is in contact with the inner side wall of the connecting box 100, and when the rotating plate 220 closes the internal circulation air inlet 101, the risk of air leakage is relatively low.

[0048] It can be understood that the sliding abutment between A and B means that A and B are in contact with each other and can slide relative to each other.

[0049] Optionally, the rotating plate 220 is a fan-shaped plate, and the internal circulation air inlet 101 is a fan-shaped hole. Thus, since the rotating plate 220 rotates within the communication box 100 to close or open the internal circulation air inlet 101, both the rotating plate 220 and the internal circulation air inlet 101 are fan-shaped. This allows for a more uniform flow rate as the fan-shaped hole is gradually closed or opened by the fan-shaped plate, facilitating more precise flow rate adjustment.

[0050] It is understandable that the shapes of the internal circulation air inlet 101 and the rotating plate 220 can also be regular shapes such as rectangle, circle, or other irregular shapes.

[0051] Specifically, the interval between the first baffle 310 and the rotating plate 220 is smaller than the interval between the second baffle 320 and the rotating plate 220 .

[0052] Optionally, the rotating plate 220 is provided with a rotating hole 221 for rotationally connecting to the connecting box 100. The axis of the rotating hole 221 coincides with the axis of the rotating ring 210. This coaxial arrangement of the rotating ring 210 and the rotating hole 221 reduces the risk of the rotating ring 210 shifting during rotation. Furthermore, the rotating hole 221 and the connecting box 100 are rotationally connected, providing a relatively stable connection.

[0053] Optionally, the air inlet direction of the internal circulation air inlet 101 is perpendicular to the air inlet direction of the fresh air inlet 102. In this way, the airflow at the internal circulation air inlet 101 and the airflow at the fresh air inlet 102 intersect vertically, and the mixing effect is better.

[0054] Optionally, both the first baffle 310 and the second baffle 320 are arc-shaped plate structures, and the end surface of the fresh air inlet 102 facing the interior of the communication box 100 is an arc-shaped surface. In this way, since the shielding portion 200 rotates within the communication box 100 to close or open the internal circulation air inlet 101, the arc-shaped first baffle 310 and the second baffle 320 cooperate with the arc-shaped end surface of the fresh air inlet 102, thereby achieving a better sealing effect.

[0055] Optionally, a rotating portion 110 is provided on the inner side wall of the communication box 100, and the rotating portion 110 is rotatably connected to the shielding portion 200. In this way, the stability of the connection is relatively high through the rotatable connection between the rotating portion 110 and the shielding portion 200.

[0056] Optionally, the rotating portion 110 includes a connecting shaft 111. The connecting shaft 111 is fixedly connected to the inner sidewall of the communication box 100 and is rotationally connected to the shielding portion 200. Thus, the connecting shaft 111 is rotationally connected to the shielding portion 200, providing a fulcrum and limit for the rotation of the shielding plate, thereby improving the stability of the rotation of the shielding portion 200.

[0057] Optionally, the axis of the connecting shaft 111 coincides with the axis of the rotating ring 210, and the connecting shaft 111 is rotatably connected to the rotating hole 221. In this way, through the cooperation between the connecting shaft 111 and the rotating hole 221, the contact area is relatively large and the connection stability is higher.

[0058] Optionally, the rotating portion 110 further includes a retaining ring 112. The retaining ring 112 is fixedly connected to the inner sidewall of the communication box 100 and is located outside the shielding portion 200 to limit the rotation of the shielding portion 200. Thus, the retaining ring 112 limits the rotation of the shielding portion 200 within the communication box 100, reducing the risk of the shielding portion 200 shifting during rotation.

[0059] Optionally, the axis of the limiting ring 112 coincides with the axis of the rotating ring 210, and the inner sidewall of the limiting ring 112 slides against the outer sidewall of the rotating ring 210. In this way, the inner sidewall of the limiting ring 112 slides against the outer sidewall of the rotating ring 210, and the limiting ring 112 provides a limit for the rotation of the rotating ring 210 in the connecting box 100, reducing the risk of the rotating ring 210 and the rotating plate 220 being offset during rotation.

[0060] Optionally, the curved surface of the fresh air inlet 102 and the inner sidewall of the limiting ring 112 are located on the same curved surface. In this way, the curved surface of the fresh air inlet 102 and the inner sidewall of the limiting ring 112 are relatively flat, without any height difference, and the process of the rotating ring 210 driving the first baffle 310 and the second baffle 320 to rotate is more stable.

[0061] Combine Figure 9As shown, the fresh air module optionally further includes a filter assembly 400. The filter assembly 400 is inserted into the communication box 100 in a direction perpendicular to the air outlet 103, and the filter assembly 400 covers the air outlet 103 to filter the outgoing air flow. In this way, the filter assembly 400 can filter both outdoor air and indoor air, eliminating the need for separate filters for indoor and outdoor air. While maintaining effective filtering, this reduces production costs and the size and weight of the air conditioner.

[0062] Optionally, the filter assembly 400 includes a filter frame 410 and a filter element 420. The filter frame 410 is inserted into the communication box 100 in a direction perpendicular to the air flow from the air outlet 103. The filter element 420 is inserted into the filter frame 410 to filter the air flow from the air outlet 103. Because the filter element 420 is made of a relatively soft material, the filter element 420 is installed in the filter frame 410, and the filter frame 410 provides support for the filter element 420, thereby ensuring the filtering effect of the filter element 420.

[0063] Optionally, a raised strip 120 is provided on the inner sidewall of the communication box 100 to provide guidance and position restraint for the filter assembly 400. Thus, the raised strip 120 provides guidance for the filter assembly 400 when inserted into the communication box 100, reducing the risk of the filter assembly 400 shifting. Furthermore, the raised strip 120 provides position restraint for the filter assembly 400, reducing the risk of the filter assembly 400 shaking within the communication box 100.

[0064] Specifically, the raised strip 120 provides guidance and positioning for the filter frame 410 .

[0065] Optionally, the rim of the fresh air inlet 102 protrudes axially from the connecting box 100. Thus, since the fresh air inlet 102 needs to be connected to the fresh air duct to connect the connecting box 100 to the outside, the rim of the fresh air inlet 102 protrudes from the surface of the connecting box 100, facilitating installation of the fresh air duct and providing relatively high connection stability.

[0066] Combine Figure 10 As shown, optionally, a driving assembly 500 is provided on one side of the communication box 100, and the driving assembly 500 is used to drive the shielding portion 200 to move in the communication box 100. In this way, the driving assembly 500 provides power for the shielding portion 200 to move in the communication box 100.

[0067] Optionally, the drive assembly 500 includes a drive motor 510 and a gear 520. The drive motor 510 is disposed outside the communication box 100. The output end of the drive motor 510 extends into the communication box 100 and connects to the gear 520. The gear 520 engages with a side wall of the shielding portion 200. Thus, the drive motor 510 provides power for the rotation of the gear 520, which in turn drives the shielding portion 200 to move within the communication box 100.

[0068] Specifically, the gear 520 is meshed with the rotating ring 210 . Thus, the driving motor 510 provides power for the gear 520 to rotate, and the gear 520 drives the rotating ring 210 to rotate in the communication box 100 .

[0069] Optionally, the communication box 100 includes a box body 130 and a cover plate 140. One side wall of the box body 130 is open, and the box body 130 is provided with an internal circulation air inlet 101 and a fresh air inlet 102. The cover plate 140 covers the open area and is provided with an air outlet 103. This allows the cover plate 140 to be opened from the box body 130, facilitating maintenance and replacement of components within the box body 130 and cleaning dust and dirt within the box body 130.

[0070] Optionally, the cover 140 is connected to the box body 130 via a snap assembly 600. The snap assembly 600 includes a snap ring 610 and a snap protrusion 620, one of which is provided on the box body 130 and the other on the cover 140. Thus, by cooperating with the snap ring 610 and the snap protrusion 620, the cover 140 can be quickly removed from the box body 130 or quickly snapped onto the box body 130. This facilitates maintenance and replacement of components within the box body 130, as well as cleaning of dust and dirt within the box body 130.

[0071] Specifically, the snap ring 610 is connected to the cover 140, and the snap protrusion 620 is connected to the box body 130. Thus, by cooperating with the snap ring 610 and the snap protrusion 620, the cover 140 can be quickly removed from the box body 130, or quickly snapped onto the box body 130. This facilitates maintenance and replacement of components within the box body 130, as well as cleaning of dust and dirt within the box body 130.

[0072] Specifically, the opening of the box body 130 and the internal circulation air inlet 101 are respectively arranged on two opposite side walls of the box body 130 .

[0073] Specifically, the fresh air inlet 102 is provided on a side wall of the box body 130 adjacent to the internal circulation air inlet 101 .

[0074] Specifically, the shielding portion 200 is disposed on the inner wall of the box body 130 .

[0075] Optionally, a fan 700 is provided on the air outlet 103 side of the communication box 100. In this way, the air flow speed in the communication box 100 is increased by the fan 700, and one fan 700 can adapt to the indoor circulation mode, fresh air mode and mixed air mode at the same time, and the production cost is relatively low.

[0076] In some embodiments, an air conditioner includes: a fresh air module as described in the above embodiments.

[0077] The air conditioner provided by the embodiment of the present disclosure includes a fresh air module as in the above-mentioned embodiment. When the shielding part 200 is rotated to the first position, the internal circulation air inlet 101 and the fresh air inlet 102 can be closed. When the shielding part 200 is rotated to the second position, the internal circulation air inlet 101 can be closed and the fresh air inlet 102 can be opened, thereby realizing the fresh air mode. When the shielding part 200 is rotated to the third position, the fresh air inlet 102 can be closed and the internal circulation air inlet 101 can be opened, thereby realizing the indoor internal circulation mode. When the shielding part 200 is rotated to the fourth position, both the fresh air inlet 102 and the internal circulation air inlet 101 can be opened, thereby realizing the mixed air mode. In addition, a variety of air supply modes can be realized to meet the different air supply needs of users. Moreover, it is only necessary to control the rotation of the shielding part 200, and the number of components to be controlled is relatively small, thereby reducing the risk of failure during long-term operation.
