[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is for reference. Figures 1-4 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0036] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, an air conditioner 100 includes a housing 10, an air duct component 20, a fan wheel 30, and an air guide assembly 40. The housing 10 has an air inlet 10a and an air outlet 10b. The air duct component 20 defines an air outlet duct 21, which connects the air inlet 10a and the air outlet 10b. The fan wheel 30 is rotatably disposed on the air duct 21. The air guide assembly 40 is disposed on the air duct component 20 and is movable at the air outlet 10b.

[0037] When the air conditioner 100 is running, the fan wheel 30 rotates, driving air to form an airflow. This allows air from outside the casing 10 to enter the air duct 21 through the air inlet 10a. After being processed by the air conditioner 100, the air is finally discharged outside the casing 10 through the air outlet 10b. During this process, the air guide assembly 40 can be in a fixed state, thus achieving directional airflow; of course, the air guide assembly 40 can also be in a movable state, thus adjusting the airflow direction and expanding the airflow range.

[0038] The air duct 21 has a first air duct wall 211 and a second air duct wall 212, which are arranged opposite to each other. In the airflow direction, both the first air duct wall 211 and the second air duct wall 212 are located downstream of the impeller 30. The first air duct wall 211 extends from the volute tongue 213 of the air duct component 20 to one side edge of the air outlet 10b. The first air duct wall 211 has a guide protrusion 2111a near the volute tongue 213 to extend the extension length of the diffuser section 214 of the air duct 21.

[0039] According to the embodiment of the present invention, the air conditioner 100 can extend the length of the diffuser section 214 of the air duct 21 by providing a guide protrusion 2111a at a position near the volute tongue 213 on the first air duct wall 211. When the impeller 30 drives the airflow through the diffuser section 214, the diffuser section 214 can increase the airflow velocity, thereby eliminating the surging noise during the operation of the air conditioner 100, improving the noise, and thus enhancing the user experience.

[0040] Reference Figure 1 For example, the air conditioner 100 also includes a heat exchanger 22, which can be located between the air inlet 10a and the impeller 30 in the airflow direction. When the air conditioner 100 is running, the impeller 30 rotates, and air outside the casing 10 enters the casing 10 through the air inlet 10a, exchanges heat with the heat exchanger 22, and the airflow after heat exchange flows through the air duct 21 and is finally discharged from the air outlet 10b under the guidance of the air guide assembly 40, thereby enabling the air conditioner 100 to achieve the effect of cooling or heating.

[0041] For example, a filter (not shown in the figure) is provided at the air inlet 10a to filter the air at the air inlet 10a. On the one hand, it can intercept large particulate matter in the air, purify the air, and improve the indoor air quality. On the other hand, it can reduce the pollution of the air to the heat exchanger 22 and ensure the heat exchange effect of the heat exchanger 22.

[0042] Reference Figure 2 and Figure 3 In some embodiments, the first duct wall 211 includes a first diffuser wall 2111 and a first guide wall 2112. The first diffuser wall 2111 extends along a first direction and at least a portion forms part of the volute tongue 213. The first guide wall 2112 extends along a second direction and is located downstream of the first diffuser wall 2111 in the airflow direction. The second direction is set at an angle to the first direction. At least a portion of the first diffuser wall 2111 protrudes from the plane containing the first guide wall 2112 to form a guide protrusion 2111a. Here, "first direction" refers to direction F1 in the figure, and "second direction" refers to direction F2 in the figure.

[0043] When the impeller 30 drives the airflow from the duct 21 to the outlet 10b, the first diffuser wall 2111 can better increase the airflow velocity, thereby reducing backflow and eddy currents during the flow to the outlet 10b and avoiding the generation of surge noise. After being accelerated by the first diffuser wall 2111, the airflow passes through the first guide wall 2112, which guides the airflow and further eliminates eddies, allowing the airflow to flow smoothly to the outlet 10b, where it is then delivered by the guide assembly 40.

[0044] In the above technical solution, by setting the first air duct wall 211 to include a first diffuser wall 2111 and a first air guide wall 2112, and by having at least a portion of the first diffuser wall 2111 protrude from the plane where the first air guide wall 2112 is located, an air guide protrusion 2111a can be formed, which can extend the length of the first diffuser wall 2111, so that the first diffuser wall 2111 can better improve the airflow velocity and eliminate the surging noise that occurs when the air conditioner 100 is running; by setting the first air guide wall 2112, eddies can be further eliminated, so that the airflow from the first diffuser wall 2111 flows smoothly to the air outlet 10b.

[0045] In some examples, the first air guide wall 2112 is located on the side away from the second air duct wall 212 on the plane where the first diffuser wall 2111 is located. On the one hand, this makes the flow area of ​​the air duct 21 gradually increase along the air outlet direction, increasing the air outlet range. On the other hand, it can extend the extension length of the diffuser section 214, increase the airflow velocity, eliminate the surging noise of the air conditioner 100 during operation, and improve the noise.

[0046] Reference Figure 3 In some specific embodiments, the extension length A of the first diffuser wall 2111 in the first direction is 10mm-100mm. For example, the extension length A of the first diffuser wall 2111 in the first direction can be 10mm, 15mm, 30mm, 50mm, 70mm, 90mm, etc.

[0047] Through extensive research, the inventors discovered that if the extension length of the first diffuser wall 2111 in the first direction is less than 10mm, that is, the extension length of the first diffuser wall 2111 in the first direction is too short, when the airflow passes through the first diffuser wall 2111, the first diffuser wall 2111 cannot effectively increase the airflow velocity, resulting in a slow airflow velocity and a tendency to produce a whistling sound; if the extension length of the first diffuser wall 2111 in the first direction is greater than 100mm, that is, the extension length of the first diffuser wall 2111 in the first direction is too long, when the airflow passes through the first diffuser wall 2111, the first diffuser wall 2111 will significantly increase the airflow velocity, but due to the excessive airflow velocity, a whistling sound will occur.

[0048] Therefore, in the above technical solution, by setting the extension length of the first diffuser wall 2111 in the first direction to 10mm-100mm, the flow rate of the airflow passing through the first diffuser wall 2111 can be increased. This not only avoids the air conditioner 100 from making a surging noise during operation, but also prevents the whistling noise caused by excessive airflow velocity. This effectively improves the abnormal noise problem of the air conditioner 100 during operation and helps to improve the user experience.

[0049] Continue to refer to Figure 3In some examples, the first diffuser wall 2111 extends for a length of A in the first direction, and the first guide wall 2112 extends for a length of B in the second direction, with the ratio of A to B being 0.3-0.5. For example, the ratio of A to B can be 0.3, 0.31, 0.35, 0.4, 0.49, 0.5, etc.

[0050] Based on the fixed overall size of the air conditioner 100, if the ratio of A to B is less than 0.3, the first diffuser wall 2111 will have an excessively short extension length in the first direction, while the first air guide wall 2112 will have an excessively long extension length in the second direction. In this case, the first diffuser wall 2111 cannot significantly increase the speed of the airflow, thus failing to eliminate the surging noise that occurs when the air conditioner 100 is running. If the ratio of A to B is greater than 0.5, the first diffuser wall 2111 will have an excessively long extension length in the first direction, while the first air guide wall 2112 will have an excessively short extension length in the second direction. In this case, the airflow velocity through the first diffuser wall 2111 will be too fast, and the air conditioner 100 will produce a whistling sound when running. Furthermore, the excessively short first air guide wall 2112 cannot effectively guide and stabilize the fast-moving airflow. When the airflow passes through the first air guide wall 2112, backflow and eddies may also occur, which will again produce surging noise and exacerbate the abnormal noise problem when the air conditioner 100 is running.

[0051] Therefore, in the above technical solution, by setting the ratio of A to B to between 0.3 and 0.5, the first diffuser wall 2111 can increase the airflow velocity and eliminate the surging noise, and the first guide wall 2112 can play a good guiding and stabilizing role on the airflow flowing through the first diffuser wall 2111, so that the airflow flows smoothly and eliminates the surging noise when the air conditioner 100 is running.

[0052] Reference Figure 3 In some examples, the angle between the first direction and the second direction is 1°-30°. For example, the angle between the first direction and the second direction can be 1°, 5°, 10°, 15°, 20°, 25°, 30°, etc.

[0053] If the angle between the first direction and the second direction of the air conditioner 100 is too small, the extension dimension of the diffuser section 214 will be too small, which will not be able to significantly increase the speed of the airflow, and thus will not be able to eliminate the surging noise that occurs when the air conditioner 100 is running. If the angle between the first direction and the second direction is too large, that is, the transition between the first diffuser wall 2111 and the first air guide wall 2112 is abrupt, the airflow will collide strongly with the first air guide wall 2112 when it flows from the first diffuser wall 2111 to the first air guide wall 2112, generating backflow and eddies, which will aggravate the abnormal noise when the air conditioner 100 is running, and the airflow will generate a velocity difference when it flows through this part, which will eventually cause the air conditioner 100 to have uneven airflow.

[0054] In the above technical solution, by setting the angle between the first direction and the second direction to 1°-30°, on the one hand, the airflow can flow more smoothly from the first diffuser wall 2111 to the first air guide wall 2112, reducing the noise problem and uneven air output problem when the air conditioner 100 is running. On the other hand, some airflow can flow along the extension direction of the first air guide wall 2122 to the gap between the air guide assembly 40 and the first air duct wall 211, which can reduce the temperature difference between the two sides of the air guide assembly 40, thereby solving the condensation problem of the air guide assembly 40.

[0055] Reference Figure 2 In some embodiments, the first air duct wall 211 includes a connecting wall 2113, which is disposed between the first diffuser wall 2111 and the first air guide wall 2112, and the connecting wall 2113 is connected to the first diffuser wall 2111 and the first air guide wall 2112 by an arc transition.

[0056] The first diffuser wall 2111 and the first air guide wall 2112 are both set at an obtuse angle to the connecting wall 2113. That is, relative to the first diffuser wall 2111, the connecting wall 2113 is located on the side of the plane where the first diffuser wall 2111 is located away from the second air duct wall 212, and the connecting wall 2113 gradually deviates from the second air duct wall 212 in the first direction along the direction away from the volute tongue 213; relative to the first air guide wall 2112, the connecting wall 2113 is located on the side of the plane where the first air guide wall 2112 is located closer to the second air duct wall 212, and the connecting wall 2113 gradually approaches the second air duct wall 212 in the second direction along the direction closer to the volute tongue 213.

[0057] Therefore, by setting a connecting wall 2113 between the first diffuser wall 2111 and the first air guide wall 2112, the first diffuser wall 2111 and the first air guide wall 2112 can be connected. By setting the connecting wall 2113 to be connected to the first diffuser wall 2111 and the first air guide wall 2112 with an arc transition, and setting the first diffuser wall 2111 and the first air guide wall 2112 at an obtuse angle to the connecting wall 2113, a smooth transition from the first diffuser wall 2111 to the first air guide wall 2112 can be achieved. This allows the airflow to flow more stably from the first diffuser wall 2111 to the first air guide wall 2112. On the one hand, this can better reduce the abnormal noise generated when the air conditioner 100 is running. On the other hand, it allows some airflow to flow along the first air guide wall 2112 to the gap between the air guide assembly 40 and the first air duct wall 211. This can reduce the temperature difference between the two sides of the air guide assembly 40, thereby solving the condensation problem of the air guide assembly 40.

[0058] Reference Figure 2 and Figure 3In some embodiments, the second duct wall 212 includes a second diffuser wall 2121 extending along a third direction, and the second diffuser wall 2121 is disposed opposite to the first diffuser wall 2111. A diffuser section 214 is located between the first diffuser wall 2111 and the second diffuser wall 2121. The angle between the first direction and the third direction is smaller than the angle between the second direction and the third direction. Here, "third direction" refers to... Figure 3 In the F3 direction.

[0059] Therefore, by setting the second diffuser wall 2121 opposite to the first diffuser wall 2111, a diffuser section 214 is formed between the first diffuser wall 2111 and the second diffuser wall 2121. When the fan wheel 30 drives the airflow through the diffuser section 214, the diffuser section 214 can increase the airflow velocity to eliminate the surge noise during the operation of the air conditioner 100.

[0060] Reference Figure 3 In some specific embodiments, the angle between the first direction and the third direction is 15°-25°. For example, the angle between the first direction and the third direction can be 15°, 16°, 18°, 20°, 24°, 25°, etc.

[0061] When the air conditioner 100 is running, the impeller 30 drives the airflow from the duct 21 to the air outlet 10b. The airflow will pass through the diffuser section 214. If the angle between the first direction and the third direction is less than 15°, that is, the diffusion angle of the diffuser section 214 is small, the diffuser section 214 cannot effectively increase the flow velocity of the airflow passing through the diffuser section 214, thus failing to eliminate the surging noise. If the angle between the first direction and the third direction is greater than 25°, that is, the diffusion angle of the diffuser section 214 is large, the diffuser section 214 will increase the airflow velocity and also cause the airflow to separate, resulting in airflow backflow and vortex phenomena, which will aggravate the abnormal noise when the air conditioner 100 is running.

[0062] Therefore, in the above technical solution, by setting the angle between the first direction and the third direction to between 15° and 25°, the flow velocity of the airflow through the diffuser section 214 can be increased while reducing airflow separation, thereby eliminating surge noise and avoiding aggravating the abnormal noise generated during the operation of the air conditioner 100.

[0063] Reference Figure 3 In some examples, the angle between the second direction and the third direction is 25°-40°. For example, the angle between the second direction and the third direction can be 25°, 26°, 30°, 35°, 39°, 40°, etc.

[0064] When the air conditioner 100 is running, after the airflow passes through the diffuser section 214, part of the airflow near the first air duct wall 211 changes direction and flows along the extension direction of the first air guide wall 2112.

[0065] If the angle between the second direction and the third direction is less than 25°, and the diffusion angle of the diffuser section 214 remains unchanged, the turning angle of the airflow is too small, requiring a longer flow path to complete the turning. This will increase the overall size of the air conditioner 100 and reduce the air outlet range. If the angle between the second direction and the third direction is greater than 40°, the turning angle of the airflow is too large, and the airflow cannot turn smoothly. It is easy to generate eddies during the turning process, which will aggravate the abnormal noise generated by the air conditioner 100 during operation.

[0066] Therefore, in the above technical solution, by setting the angle between the second direction and the third direction to 25°-40°, the airflow near the first air duct wall 211 can be smoothly turned so that the airflow can flow smoothly along the extension direction of the first air guide wall 2112.

[0067] Reference Figure 1 and Figure 2 In some examples, the air outlet 10b includes a first air outlet 10b1 and a second air outlet 10b2 connected together. The first air duct wall 211 also includes a first air outlet wall 2114. The first air outlet wall 2114 is located between the first air guide wall 2112 and the first air outlet 10b1 in the airflow direction. The first air outlet wall 2114 is a first arc-shaped wall. In the second direction, the first arc-shaped wall gradually approaches the second air outlet 10b2 in a direction away from the first air guide wall 2112.

[0068] This design serves two purposes: firstly, it avoids the air guide component 40 from colliding with the first air outlet wall 2114 when the air guide component 40 is moving at the air outlet 10b, thus preventing it from affecting the air guiding effect of the air guide component 40; secondly, it allows for adjustment of the air outlet angle of the air outlet 10b, thereby improving the air outlet effect of the air conditioner 100.

[0069] Reference Figure 1 and Figure 3 The second air duct wall 212 also includes a second air outlet wall 2122. The second air outlet wall 2122 is located between the second diffuser wall 2121 and the second air outlet 10b2 in the airflow direction. The second air outlet wall 2122 is a second arc-shaped wall. In the third direction, the second arc-shaped wall gradually moves away from the first air guide wall 2112 in a direction away from the second diffuser wall 2121.

[0070] Therefore, by setting the second air outlet wall 2122 as the second arc-shaped wall, and making the second arc-shaped wall gradually move away from the first air guide wall 2112 in the direction away from the second diffuser wall 2121 in the third direction, on the one hand, it can avoid the air guide component 40 and prevent the air guide component 40 from colliding with the second air outlet wall 2122, thereby affecting the air guide effect of the air guide component 40. On the other hand, it can play the role of air guide, thereby increasing the air output of the air conditioner 100.

[0071] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the air outlet 10b includes a first air outlet 10b1 and a second air outlet 10b2 connected together. The first air outlet 10b1 is close to the first air duct wall 211, and the second air outlet 10b2 is close to the second air duct wall 212.

[0072] Furthermore, the air guide assembly 40 includes a first air guide plate 41 and a second air guide plate 42. The first air guide plate 41 is rotatably disposed on the air duct component 20 and is used to open and close the first air outlet 10b1. The second air guide plate 42 is rotatably disposed on the air duct component 20 and is used to open and close the second air outlet 10b2.

[0073] Specifically, when the air conditioner 100 is in the off state, the first air outlet 10b1 can be closed by the first air guide plate 41 and the second air outlet 10b2 can be closed by the second air guide plate 42, so as to close the air outlet 10b, reduce the possibility of external dust and other impurities entering the air duct 21 and damaging the internal structure of the air conditioner 100, and help protect the air conditioner 100.

[0074] When the air conditioner 100 is turned on, the first air outlet 10b1 can be opened by the first air guide plate 41, and the second air outlet 10b2 can be opened by the second air guide plate 42, so that at least one of the first air outlet 10b1 and the second air outlet 10b2 is in the open state, so as to open the air outlet 10b and allow the air conditioner 100 to discharge cold or hot air to the outside, thereby achieving the cooling or heating effect.

[0075] In other words, when the air conditioner 100 is turned on, the air outlet direction of the air conditioner 100 can be adjusted by adjusting the state of the first air guide plate 41 and the second air guide plate 42, so as to achieve multiple working states with different air outlet directions.

[0076] Specifically, in this application, if the air conditioner 100 is a wall-mounted air conditioner, the airflow in the duct 21 can be directed downwards by adjusting the first air guide plate 41 and the second air guide plate 42 to a vertical position; alternatively, the airflow in the duct 21 can be directed forwards by adjusting the first air guide plate 41 and the second air guide plate 42 to a horizontal position. Of course, the airflow can also be directed forwards by controlling the rotation of the first air guide plate 41 and / or the second air guide plate 42 to achieve a sweeping effect, thereby expanding the airflow range.

[0077] Specifically, when the air conditioner 100 is in heating mode, adjusting the first air guide plate 41 and the second air guide plate 42 directs the hot airflow downwards, bringing it closer to the wall. This facilitates a stronger Coanda effect, making the hot air stream more concentrated, increasing airflow volume, improving the grounding of the hot air, and allowing it to roll a greater distance along the floor. Furthermore, hot air is lighter than cold air, causing the downward-flowing hot air to rise under gravity, increasing the rate of temperature rise in the foot warmer and the overall room temperature, resulting in better foot warming and significantly improved room temperature uniformity.

[0078] When the air conditioner 100 is in cooling mode, adjusting the first air guide plate 41 and the second air guide plate 42 causes the cold air to flow forward or upward. The cold air will descend under the action of gravity, which can accelerate the indoor air circulation, significantly improve the indoor cooling speed and temperature uniformity, and improve the user's comfort.

[0079] Therefore, in the above technical solution, by setting the air guide assembly 40 to include a first air guide plate 41 and a second air guide plate 42, the first air outlet 10b1 can be opened and closed by the first air guide plate 41, and the second air outlet 10b2 can be opened and closed by the second air guide plate 42. Thus, air can be delivered at different angles according to the user's actual needs, thereby improving the user's user experience.

[0080] In addition, when the first air guide plate 41 guides the air, the airflow passing through the first air duct wall 211 will flow on the two oppositely arranged surfaces of the first air guide plate 41, avoiding the temperature difference between the two sides of the first air guide plate 41, thereby solving the problem of condensation on the first air guide plate 41.

[0081] Reference Figures 1-4 In some specific embodiments, the air conditioner 100 is a wall-mounted air conditioner, and the length of the air conditioner 100 extends in the left-right direction and the height extends in the up-down direction.

[0082] The first air duct wall 211 is located above the second air duct wall 212, the first air outlet 10b1 is located at the lower front side of the air conditioner 100, and the second air outlet 10b2 is located at the bottom front side of the air conditioner body.

[0083] Therefore, this wall-mounted air conditioner can eliminate surging noise, improve abnormal noise during operation, and also solve the condensation problem of the first air guide plate 41.

[0084] In some embodiments, the first air guide plate 41 is rotatably disposed on the air duct component 20 via the first rotating shaft 411, and the second air guide plate 42 is rotatably disposed on the air duct component 20 via the second rotating shaft 421.

[0085] For example, the first rotating shaft 411 is located above the second rotating shaft 421. The first rotating shaft 411 is disposed away from the second air outlet 10b2 in the vertical direction, and the second rotating shaft 421 is disposed close to the first air outlet 10b1 in the front-back direction. The first air guide plate 41 has a first proximal end close to the first rotating shaft 411 and a first distal end away from the first rotating shaft 411 in its extending direction, and the second air guide plate 42 has a second proximal end close to the second rotating shaft 421 and a second distal end away from the second rotating shaft 421 in its extending direction.

[0086] When the air conditioner 100 is in the off state, the first proximal end of the first air guide plate 41 faces upward and the first distal end of the first air guide plate 41 faces downward, the second proximal end of the second air guide plate 42 faces forward and the second distal end of the second air guide plate 42 faces backward.

[0087] When the air conditioner 100 is in the first heating mode, the first air guide plate 41 rotates to a first vertical state with the first proximal end facing up and the first distal end facing down relative to the state of the first air outlet 10b1 being closed, and the second air guide plate 42 rotates to a second vertical state with the second proximal end facing up and the second distal end facing down relative to the state of the second air outlet 10b2 being closed.

[0088] The first vertical state refers to the first air guide plate 41 extending in the vertical direction or in a direction at a certain angle to the vertical direction, and the second vertical state refers to the second air guide plate 42 extending in the vertical direction or in a direction at a certain angle to the vertical direction.

[0089] In this mode, the first proximal end is higher than the second proximal end, and the second distal end is lower than the first distal end. The second air guide plate 42 is located on the side of the first air guide plate 41 facing the air duct 21 and the second proximal end is close to the first air guide plate 41. The first air guide plate 41 extends from top to bottom in a direction away from the air duct 21 to avoid the second air guide plate 42. The first air guide plate 41 and the second air guide plate 42 cooperate with each other to extend the air guiding distance.

[0090] When the air conditioner 100 is in the second heating mode, the first air guide plate 41 rotates relative to the state where the first air outlet 10b1 is closed to a state where the first proximal end is close to the air duct 21 and the first distal end is far away from the air duct 21, and the second air guide plate 42 rotates relative to the state where the second air outlet 10b2 is closed to a state where the second distal end is close to the air duct 21 and the second proximal end is far away from the air duct 21, so that a heating air supply channel is defined between the first air guide plate 41 and the second air guide plate 42.

[0091] In this mode, both the first air guide plate 41 and the second air guide plate 42 extend obliquely from top to bottom in a direction away from the air duct 21, and the second air guide plate 42 and the first air guide plate 41 are parallel to each other or oblique to each other. The first air guide plate 41 and the second air guide plate 42 are adapted to reciprocate in the same direction or rotate in the same direction to the target position.

[0092] When the air conditioner 100 is in cooling mode, the first air guide plate 41 rotates relative to the state where the first air outlet 10b1 is closed, so that the first proximal end is close to the air duct 21 and the first distal end is far away from the air duct 21. The second air guide plate 42 rotates relative to the state where the second air outlet 10b2 is closed, so that the second distal end is close to the air duct 21 and the second proximal end is far away from the air duct 21, so that a cooling air supply channel is defined between the first air guide plate 41 and the second air guide plate 42.

[0093] In this mode, both the first air guide plate 41 and the second air guide plate 42 extend at an angle from top to bottom away from the air duct 21, and the distance between the second air guide plate 42 and the first air guide plate 41 gradually increases along the air flow direction.

[0094] When the air conditioner 100 is in the anti-direct-blow mode, the first air guide plate 41 rotates relative to the state of closing the first air outlet 10b1 to a state of tilting and extending from top to bottom away from the air duct 21, and the second air guide plate 42 rotates relative to the state of closing the second air outlet 10b2 to a state of tilting and extending from bottom to top away from the air duct 21.
