Description

Technical Field

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

[0002] Fresh air air conditioners are traditional air conditioners that incorporate a fresh air function. This allows the air conditioner to not only regulate indoor temperature and humidity but also deliver fresh, oxygen-rich air from outside, mitigating the deterioration of air quality caused by prolonged indoor confinement. The fresh air module independently delivers outdoor air indoors. In situations where there is a large temperature difference between indoor and outdoor, directly introducing fresh air indoors can cause significant temperature fluctuations within a short period of time, resulting in a poor user experience.

[0003] A related art fresh air air conditioner includes an air intake module within its indoor unit. The module has a circulation cavity, an outdoor air inlet, and an indoor air inlet connected to the cavity. Both the indoor and outdoor air inlets are equipped with electrically controlled valves. By controlling the electrically controlled valves to open the outdoor and indoor air inlets, outdoor air is mixed with indoor air before being delivered indoors, reducing the risk of large fluctuations in indoor temperature over a short period of time and improving the 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] During the operation of the air conditioner, it is necessary to control the operation of multiple electronically controlled valves. After long-term use, the risk of operational failure is high and the reliability is relatively low.

[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. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The embodiment of the present disclosure provides an air conditioner, which only needs to control the activity of the fresh air valve to achieve air mixing during the operation of the air conditioner, making the operation control simpler, reducing the risk of operation failure during long-term use, and improving reliability.

[0009] In some embodiments, an air conditioner includes: a connecting box, an internal circulation valve, and a fresh air valve. The connecting box is provided with an internal circulation air inlet, a fresh air inlet, and an air outlet; the internal circulation valve is used to open or close the internal circulation air inlet; the fresh air valve is used to open or close the fresh air inlet, and the fresh air valve and the internal circulation valve are connected by a linkage mechanism so that the two can move in a linked manner; wherein, when the fresh air valve moves from a first position to a second position, the fresh air inlet gradually changes from an open state to a closed state, and simultaneously, the linkage mechanism links the internal circulation valve to move from a third position to a fourth position, so that the internal circulation air inlet gradually changes from a closed state to an open state.

[0010] Optionally, the linkage mechanism includes: a first linkage portion and a second linkage portion. The first linkage portion is provided on the fresh air valve; the second linkage portion is slidably connected to the first linkage portion and is provided on the internal circulation valve; wherein the sliding distance between the first linkage portion and the second linkage portion is smaller than the movable distance of the internal circulation valve.

[0011] Optionally, one of the first linkage part and the second linkage part is a linkage plate and the other is a sliding groove, and one end of the linkage plate extends into the sliding groove and is slidably connected to the sliding groove.

[0012] Optionally, the internal circulation valve is a baffle, which is located on the outside of the connecting box and can be covered at the internal circulation air inlet.

[0013] Optionally, the communication box comprises: a box body and a cover plate. One side wall of the box body is open, and the box body is provided with an internal circulation air inlet and a fresh air inlet; the cover plate is arranged on the open area and is provided with an air outlet.

[0014] Optionally, the air conditioner further comprises: a filter assembly, wherein the filter assembly is inserted into the communication box along a direction perpendicular to the air outlet direction of the air outlet, and a filter assembly cover is provided at the air outlet.

[0015] Optionally, a driving motor is provided on the outside of the connecting box to drive the movement of the fresh air valve.

[0016] Optionally, a butt joint is provided at the edge of the fresh air inlet.

[0017] Optionally, a fan is provided on the air outlet side of the communication box.

[0018] Optionally, the air inlet direction of the internal circulation air inlet is perpendicular to the air inlet direction of the fresh air inlet.

[0019] The air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0020] Since the linkage mechanism links the internal circulation valve to move from the third position to the fourth position as the fresh air valve moves from the first position to the second position, the internal circulation valve can be linked and controlled by simply controlling the fresh air valve. This simplifies the operation and control logic, reduces the risk of failure during long-term use, and improves reliability. Furthermore, the fresh air inlet gradually transitions from an open state to a closed state, while the internal circulation inlet gradually transitions from a closed state to an open state. This allows for the adjustment of the ratio of indoor and outdoor air flowing into the connecting box, more accurately adjusting the temperature of the air flowing into the room, and reducing the risk of large fluctuations in indoor temperature over a short period of time.

[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 1-4 As shown, an embodiment of the present disclosure provides an air conditioner, comprising: a connecting box 100, an internal circulation valve 200, and a fresh air valve 300. The connecting box 100 is provided with an internal circulation air inlet 101, a fresh air inlet 102, and an air outlet 103; the internal circulation valve 200 is used to open or close the internal circulation air inlet 101; the fresh air valve 300 is used to open or close the fresh air inlet 102, and the fresh air valve 300 and the internal circulation valve 200 are connected by a linkage mechanism 400, so that the activities of the two are linked; wherein, in the process of the fresh air valve 300 moving from the first position to the second position, the fresh air inlet 102 gradually changes from the open state to the closed state, and at the same time, the linkage mechanism 400 links the internal circulation valve 200 to move from the third position to the fourth position, so that the internal circulation air inlet 101 gradually changes from the closed state to the open state.

[0042] With the air conditioner provided by the embodiment of the present disclosure, since the linkage mechanism 400 links the internal circulation valve 200 to move from the third position to the fourth position during the movement of the fresh air valve 300 from the first position to the second position, it is only necessary to control the fresh air valve 300 to achieve mixed air, and the internal circulation valve 200 can be linked and controlled. The operation and control logic is simpler, the risk of failure during long-term use is relatively low, and the reliability is higher. In addition, the fresh air inlet 102 gradually changes from an open state to a closed state, and the internal circulation inlet 101 gradually changes from a closed state to an open state, which can adjust the ratio of indoor air and outdoor air flowing into the connecting box 100, more accurately adjust the temperature of the air flowing into the room, and reduce the risk of large fluctuations in indoor temperature in a short period of time.

[0043] It can be understood that the second position refers to the position where the fresh air valve 300 blocks the fresh air inlet 102, and the first position refers to the position where the fresh air valve 300 controls the opening of the fresh air inlet 102. The movement of the fresh air valve 300 from the first position to the second position means that the fresh air valve 300 moves toward the internal circulation air inlet 101.

[0044] Combine Figures 3 to 7 As shown, the linkage mechanism 400 optionally includes a first linkage portion 410 and a second linkage portion 420. The first linkage portion 410 is disposed on the fresh air valve 300; the second linkage portion 420 is slidably connected to the first linkage portion 410 and is disposed on the internal circulation valve 200; wherein the sliding distance between the first linkage portion 410 and the second linkage portion 420 is less than the movable distance of the internal circulation valve 200. Thus, as the fresh air valve 300 moves from the first position to the second position, the fresh air inlet 102 gradually transitions from an open state to a closed state. Simultaneously, the fresh air valve 300 drives the internal circulation valve 200 from the third position to the fourth position via the first linkage portion 410 and the second linkage portion 420, thereby gradually transitioning the internal circulation air inlet 101 from a closed state to an open state. The fresh air valve 300 can be stopped at any time during its movement from the first position to the second position, thereby enabling a mixed air mode, and the mixed air ratio can be adjusted. After the fresh air inlet 102 is closed, the internal circulation air inlet 101 is opened to realize the indoor internal circulation mode.

[0045] The fresh air damper 300 moves in the opposite direction from the first position to the fifth position, gradually closing the fresh air inlet 102. Since the first linkage portion 410 and the second linkage portion 420 can slide relative to each other, the internal circulation valve 200 remains in the same position. This allows both the internal circulation air inlet 101 and the fresh air inlet 102 to remain closed simultaneously, reducing the risk of indoor and outdoor dust entering the communication box 100.

[0046] Similarly, as the fresh air damper 300 moves from the second position to the sixth position, the fresh air inlet 102 gradually transitions from a closed state to an open state. Because the first linkage 410 and the second linkage 420 can slide relative to each other, the internal circulation valve 200 remains in the same position. This allows both the internal circulation air inlet 101 and the fresh air inlet 102 to remain open simultaneously, enabling a wider range of air intake modes to meet diverse user needs.

[0047] When the sliding distance between the first linkage part 410 and the second linkage part 420 is greater than or equal to the movable distance of the internal circulation valve 200, the sliding distance between the first linkage part 410 and the second linkage part 420 is too long, and there is a greater risk that the internal circulation damper remains stationary during the movement of the fresh air valve 300 from the first position to the second position.

[0048] Optionally, the sliding distance between the first linkage part 410 and the second linkage part 420 is greater than or equal to the width of the internal circulation air inlet 101. In this way, when the sliding distance between the first linkage part 410 and the second linkage part 420 is less than the width of the internal circulation air inlet 101, the sliding distance between the first linkage part 410 and the second linkage part 420 is too small. After the fresh air valve 300 moves to open the fresh air inlet 102 to the maximum flow rate, the internal circulation valve 200 is likely to follow the linkage, resulting in a greater risk of the internal circulation air inlet 101 not being tightly closed and a greater risk of difficulty in generating linkage.

[0049] Optionally, one of the first linkage portion 410 and the second linkage portion 420 is a linkage plate 421 and the other is a sliding groove 411, and one end of the linkage plate 421 extends into the sliding groove 411 and is slidably connected to the sliding groove 411. In this way, when one end of the linkage plate 421 extends into the sliding groove 411, the sliding groove 411 can provide guidance and limit for the linkage plate 421, and the sliding stability is relatively high.

[0050] Specifically, a sliding groove 411 is provided on the fresh air valve 300, and a linkage plate 421 is provided on the internal circulation valve 200. In this way, one end of the linkage plate 421 extends into the sliding groove 411, and the sliding groove 411 can provide guidance and limitation for the linkage plate 421, and the sliding stability is relatively high. After the fresh air valve 300 moves for a certain distance, the linkage plate 421 slides in the sliding groove 411, and the position of the internal circulation valve 200 remains unchanged. The fresh air valve 300 continues to move, and after the linkage plate 421 abuts against the end side wall of the sliding groove, linkage is generated, and the position of the internal circulation valve 200 changes accordingly. After the fresh air valve 300 moves in the opposite direction, the linkage plate 421 slides in the sliding groove 411, and the position of the internal circulation valve 200 remains unchanged until the linkage plate 421 abuts against the other end side wall of the sliding groove.

[0051] Optionally, the fresh air inlet 102 is a grille-type inlet, and the fresh air valve 300 is a movable plate 310. The movable plate 310 is provided with through holes 311. The through holes 311 are grille-type, compatible with the grille-type fresh air inlet 102. In this way, the through holes 311 on the movable plate 310 are compatible with the fresh air inlet 102, making the width of the fresh air inlet 102 relatively narrow. The fresh air valve 300 can quickly close or open the fresh air inlet 102.

[0052] Specifically, the fresh air inlet 102 is a rectangular hole, and the through hole 311 is a rectangular hole.

[0053] Optionally, the movable plate 310 is located inside the communication box 100, and the movable plate 310 abuts against a side wall of the communication box 100 provided with the fresh air inlet 102. In this way, the movable plate 310 moves inside the communication box 100, reducing the space occupied outside the communication box 100 and facilitating better placement inside the air conditioner.

[0054] Optionally, the movable plate 310 moves in the communication box 100 along the opening direction of the internal circulation air inlet 101. In this way, the moving direction of the movable plate 310 is consistent with the opening direction of the internal circulation air inlet 101. During the movement of the movable plate 310, it is linked with the internal circulation valve 200. The internal circulation valve 200 can also move along the opening direction of the internal circulation air inlet 101, thereby better closing or opening the internal circulation air inlet 101.

[0055] It can be understood that the opening direction of the internal circulation air inlet 101 is perpendicular to the plane where the side wall of the communication box 100 on which the internal circulation air inlet 101 is provided is located.

[0056] Optionally, a driving motor 510 is provided on the outside of the communication box 100 for driving the fresh air valve 300 to move. In this way, the driving motor 510 provides power for the fresh air valve 300 to move.

[0057] Optionally, a gear 520 is provided at the output end of the driving motor 510, and the gear 520 is engaged with the fresh air valve 300. In this way, the driving motor 510 and the gear 520 provide power for the fresh air valve 300 to move.

[0058] Optionally, the output end of the drive motor 510 passes through the communication box 100 and is connected to a gear 520 inside the communication box 100. The gear 520 engages with a side edge of the movable plate 310. The drive motor 510 cooperates with the gear 520 to provide power for the movable plate 310 to move within the communication box 100 along the opening direction of the internal circulation air inlet 101. In this way, the drive motor 510 provides power for the rotation of the gear 520, and the gear 520 drives the movable plate 310 to move within the communication box 100.

[0059] Specifically, the driving motor 510 is disposed outside the box body 110 , and an output end of the driving motor 510 passes through the box body 110 and is connected to a gear 520 inside the box body 110 .

[0060] Optionally, the internal circulation valve 200 is a baffle 210, which is located outside the communication box 100 and can cover the internal circulation air inlet 101. In this way, during the movement of the fresh air valve 300, the baffle 210 is driven to move by the linkage mechanism 400, so that the baffle 210 covers the internal circulation air inlet 101 or is away from the internal circulation air inlet 101. Moreover, the baffle 210 is located outside the communication box 100. When the baffle 210 covers the internal circulation air inlet 101, the airflow at the internal circulation air inlet 101 is opposite to the direction of movement of the baffle 210, thereby reducing the risk of air leakage caused by the baffle 210 being blown by the airflow.

[0061] Combine Figure 7 and Figure 8 As shown, the linkage plate 421 optionally includes a first plate portion 4211 and a second plate portion 4212. The first plate portion 4211 is fixedly connected to the baffle 210 and extends into the communication box 100 along the movable direction of the baffle 210. One end of the second plate portion 4212 is perpendicularly arranged to the first plate portion 4211 and fixedly connected to the end of the first plate portion 4211 facing away from the baffle 210. The other end of the second plate portion 4212 is slidably connected to the sliding groove 411. In this way, the movable plate 310 moves and, in cooperation with the sliding groove 411 and the second plate portion 4212, drives the first plate portion 4211 and the baffle 210 to move. The first plate portion 4211 and the second plate portion 4212 are perpendicularly arranged, so that the distance between the second plate portion 4212 and the second plate portion 4212 is relatively large, and the risk of interference is relatively low.

[0062] Optionally, a sliding hole 4213 is provided on the second plate portion 4212, and the inner side of the sliding hole 4213 is slidably connected to a sliding rod 4214, which is inserted into the communication box 100. In this way, the sliding rod 4214 cooperates with the sliding hole 4213 to provide a limit and guide for the second plate portion 4212, reducing the risk of the second plate portion 4212 being offset during movement.

[0063] Optionally, a first plug hole 4215 is provided on one side wall of the communication box 100, and the slide bar 4214 is inserted into the communication box 100 through the first plug hole 4215. In this way, the slide bar 4214 can be quickly inserted into the communication box 100 through the first plug hole 4215 and connected to the slide hole 4213, which makes assembly and disassembly more efficient.

[0064] Combine Figure 9As shown, the communication box 100 optionally includes a box body 110 and a cover plate 120. One side wall of the box body 110 is open, and the box body 110 is provided with an internal circulation air inlet 101 and a fresh air inlet 102. The cover plate 120 covers the open area and is provided with an air outlet 103. This allows the cover plate 120 to be opened from the box body 110, facilitating maintenance and replacement of components within the box body 110, as well as cleaning dust and dirt within the box body 110.

[0065] Optionally, the cover 120 is connected to the box body 110 via a snap assembly 130. The snap assembly 130 includes a snap ring 131 and a snap protrusion 132, one of which is provided on the box body 110 and the other on the cover 120. Thus, by engaging the snap ring 131 and the snap protrusion 132, the cover 120 can be quickly removed from the box body 110 or quickly snapped onto the box body 110. This facilitates maintenance and replacement of components within the box body 110, as well as cleaning of dust and dirt within the box body 110.

[0066] Specifically, the snap ring 131 is connected to the cover 120, and the snap protrusion 132 is connected to the box body 110. Thus, by cooperating with the snap ring 131 and the snap protrusion 132, the cover 120 can be quickly removed from the box body 110, or quickly snapped onto the box body 110. This facilitates maintenance and replacement of components within the box body 110, as well as cleaning of dust and dirt within the box body 110.

[0067] Combine Figure 10 As shown, the air conditioner optionally further includes a filter assembly 600. The filter assembly 600 is inserted into the communication box 100 in a direction perpendicular to the air outlet 103, and the filter assembly 600 covers the air outlet 103. In this way, the filter assembly 600 can filter both outdoor and indoor air, eliminating the need for separate filters for indoor and outdoor air. This reduces production costs while ensuring effective filtering, and also reduces the size and weight of the air conditioner.

[0068] Optionally, the filter assembly 600 includes a filter frame 610 and a filter element 620. The filter frame 610 is inserted into the communication box 100 in a direction perpendicular to the air flow from the air outlet 103. The filter element 620 is inserted into the filter frame 610 to filter the air flow from the air outlet 103. Because the filter element 620 is made of a relatively soft material, the filter element 620 is installed in the filter frame 610, and the filter frame 610 provides support for the filter element 620, thereby ensuring the filtering effect of the filter element 620.

[0069] Optionally, a butt joint 140 is provided at the edge of the fresh air inlet 102. In this way, it is more convenient to connect the fresh air duct of the air conditioner through the butt joint 140, and the stability of the connection is relatively high.

[0070] Optionally, the butt joint 140 is fixedly connected to the box body 110, and the flow rate of the butt joint plate gradually decreases as it faces away from the box body 110. In this way, the narrower end is the air inlet end of the butt joint 140, and the flow rate of the airflow increases after entering the butt joint 140, and the flow resistance of the airflow is relatively small.

[0071] 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.

[0072] Specifically, the opening of the box body 110 and the internal circulation air inlet 101 are respectively arranged on two opposite side walls of the box body 110 .

[0073] Specifically, the fresh air inlet 102 is provided on a side wall of the box body 110 adjacent to the internal circulation air inlet 101 .

[0074] 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.

[0075] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
