Description

Technical Field

[0001] The present invention relates to the field of refrigeration equipment, and more specifically, to an air conditioner. Background Art

[0002] In the existing air conditioners, the heat exchanger and the wind wheel are relatively fixed, and the air conditioner can only blow cold air or be used as a fan, and cannot blow mixed air.

[0003] Although a few air conditioners can provide mixed air, they will add many additional components or adopt the method of guiding air.

[0004] Adding many additional components or the method of guiding air has the following disadvantages:

[0005] 1) Increase the cost of the air conditioner and the mixing effect is weak;

[0006] 2) The degree of mixing effect and the degree of adjustment are not high. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0008] For this reason, the object of the present invention is to provide an air conditioner.

[0009] To achieve the above object, the technical solution of the present invention provides an air conditioner, including: a housing that defines an installation space, and an air inlet is provided on the housing, and the air inlet includes a first air inlet area and a second air inlet area; a heat exchanger and a wind wheel, both located in the installation space, the heat exchanger does not completely cover the first air inlet area and the second air inlet area, the heat exchanger and the wind wheel can move relative to each other, and the wind wheel has a preset position, at the preset position, along the length direction of the air inlet, part of the wind wheel covers the heat exchanger, and part of the wind wheel covers at least part of the area in the first air inlet area and the second air inlet area that is not covered by the heat exchanger.

[0010] In the air conditioner provided by the above technical solution of the present invention, at the preset position, the wind wheel sucks air from the first air inlet area and the second air inlet area. Specifically, the air entering through the first air inlet area and the second air inlet area covered by the heat exchanger is non-natural air, and the air entering through the first air inlet area and the second air inlet area not covered by the heat exchanger is normal temperature air (or natural air). The non-natural air and the natural air are mixed in the wind wheel to obtain mixed air, which improves the comfort of the air output by the air conditioner.

[0011] In this application, a mixed wind is blown out through the relative movement between the wind wheel and the heat exchanger. The structure is simple, the cost is low, and by controlling the relative position between the wind wheel and the heat exchanger, the ratio of non-natural wind to natural wind can be changed, achieving a stepless mixing effect. The mixing effect is good and the mixing degree is easy to adjust.

[0012] In addition, the air conditioner provided by the above technical solution of the present invention further has the following additional technical features:

[0013] In the above technical solution, the heat exchanger is correspondingly arranged with the first air inlet area, the wind wheel can move relative to the heat exchanger between a first position covering the first air inlet area and a second position covering the second air inlet area, and the preset position is between the first position and the second position.

[0014] The heat exchanger is arranged corresponding to the first air inlet area, that is, at least part of the heat exchanger covers the first air inlet area, and the wind wheel can move relative to the heat exchanger between the first position and the second position. In this way, at the first position, at least part of the air inhaled by the wind wheel is non-natural wind that sequentially passes through the first air inlet area and the heat exchanger. At the second position, at least part of the air inhaled by the wind wheel is normal temperature wind (or natural wind) from the second air inlet area. At the preset position, part of the wind wheel corresponds to the first air inlet area and part corresponds to the second air inlet area. Thus, the wind wheel can simultaneously inhale non-natural wind passing through the heat exchanger from the first air inlet area and natural wind from the second air inlet area, and mix them inside the wind wheel to obtain a mixed wind. The wind wheel slides between the first position and the second position relative to the heat exchanger and passes through the preset position during the sliding process, which can enable the wind wheel to simultaneously inhale non-natural wind and natural wind, mix them inside the wind wheel, obtain a mixed wind, and improve the comfort of the air blown out by the air conditioner.

[0015] In any of the above technical solutions, at the first position, the wind wheel completely corresponds to the first air inlet area.

[0016] At the first position, the wind wheel is completely arranged corresponding to the first air inlet area. At this time, the refrigeration or heating effect of the air conditioner is the strongest, thereby improving the utilization rate of the heat exchanger. At the second position, part of the wind wheel corresponds to the first air inlet area and part corresponds to the second air inlet area. During the movement of the wind wheel relative to the heat exchanger, there are multiple preset positions.

[0017] In any of the above technical solutions, the air conditioner includes: a first driving device, located in the installation space and connected to the wind wheel, for driving the wind wheel to rotate around its own axis, and the first driving device moves with the wind wheel relative to the heat exchanger between the first position and the second position.

[0018] The first driving device moves with the wind wheel to ensure that at the first position, the second position, and any position between the first position and the second position, the first driving device can drive the wind wheel to rotate around the axis of the wind wheel. The first driving device is connected to the wind wheel and drives the wind wheel to rotate along the axis direction of the wind wheel, so as to suck the air flow in the first air inlet area and / or the second air inlet area into the air duct and flow out from the air outlet.

[0019] In any of the above technical solutions, the air conditioner includes: a bearing and a bearing seat, and the bearing and the bearing seat are supported between the wind wheel and the housing, and move with the wind wheel relative to the heat exchanger between the first position and the second position.

[0020] Both the bearing and the bearing seat are located in the installation space. The inner ring of the bearing is fixedly connected to the wind wheel, the outer ring of the bearing is connected to the bearing seat, and the bearing seat is arranged on the housing, which not only realizes the installation of the wind wheel on the housing, but also realizes the rotation of the wind wheel relative to the housing around its own axis. The bearing and the bearing seat move with the wind wheel relative to the heat exchanger, so that at the first position, the second position, and any position between the first position and the second position, the bearing and the bearing seat can support the wind wheel well.

[0021] In any of the above technical solutions, a wind guiding wall is provided in the housing, the wind guiding wall encloses an air duct, the wind wheel is located in the air duct, an air outlet is provided on the housing, and the air duct communicates at least one of the first air inlet area and the second air inlet area corresponding to the wind wheel with the air outlet.

[0022] "The air duct communicates at least one of the first air inlet area and the second air inlet area corresponding to the wind wheel with the air outlet" means that when the wind wheel corresponds to the first air inlet area, the air duct can communicate the first air inlet area with the air outlet; when the wind wheel corresponds to the second air inlet area, the air duct can communicate the second air inlet area with the air outlet; when the wind wheel corresponds to both the first air inlet area and the second air inlet area at the same time, the air duct can communicate the first air inlet area with the air outlet and can also communicate the second air inlet area with the air outlet.

[0023] Through the setting of the air duct, under the action of the wind wheel, the air flow entering the air duct from at least one of the first air inlet area and the second air inlet area can flow out from the air outlet.

[0024] In any of the above technical solutions, the wind guiding wall is fixed on the housing, the air duct communicates with both the first air inlet area and the second air inlet area, and the wind wheel moves relative to the air duct between the first position and the second position; or, the wind guiding wall is connected to the wind wheel and moves with the wind wheel relative to the heat exchanger between the first position and the second position.

[0025] In a specific embodiment, the air guiding wall is fixed to the housing, so that the air duct is also stationary relative to the housing. That is, when the wind wheel moves relative to the heat exchanger, the wind wheel also moves relative to the air duct. The arrangement in which the air duct is stationary relative to the housing can reduce the complexity of the air conditioner, but it is necessary to ensure the length of the air duct in the direction from the first air inlet area to the second air inlet area to ensure that the air duct can connect the first air inlet area and the air outlet, and can also connect the second air inlet area and the air outlet.

[0026] In another specific embodiment, the air guiding wall is connected to the wind wheel and moves relative to the heat exchanger along with the wind wheel. The air guiding wall and the wind wheel can be fixedly connected, so that the air guiding wall moves relative to the heat exchanger along with the wind wheel, and thus the air duct moves relative to the heat exchanger along with the wind wheel. The second driving device is connected to the air guiding wall or the wind wheel to drive the wind wheel and the air guiding wall to move between a first position and a second position relative to the heat exchanger. For example, the second driving device includes a motor, a gear is connected to the motor shaft, and a rack meshing with the gear is connected to the air guiding wall or the wind wheel, which realizes the driving of the air guiding wall and the wind wheel by the second driving device. Alternatively, the air guiding wall and the wind wheel are movably connected or not connected, and the second driving device is used to drive the wind wheel to move between a first position and a second position relative to the heat exchanger. The air conditioner further includes a third driving device, and the third driving device is connected to the air guiding wall to drive the air guiding wall to move between a first position and a second position relative to the heat exchanger along with the wind wheel.

[0027] In any of the above technical solutions, the air conditioner includes: a purification device disposed at the second air inlet area.

[0028] In the related art, the purification device is disposed on the heat exchanger and corresponds to the first air inlet area. The air flow entering the installation space from the first air inlet area needs to pass through the purification device and the heat exchanger, resulting in a large air inlet resistance. In the present application, the purification device is disposed at the second air inlet area, that is, the purification device corresponds to the second air inlet area. After the air flow entering from the second air inlet area passes through the purification device, it passes through the wind wheel and then flows out from the wind wheel to the air outlet, which not only realizes the purification of the air flow but also reduces the air inlet resistance.

[0029] The purification device can be a HEPA filtration device (high-efficiency air filtration device or high-efficiency air filter or high-efficiency air filter mesh) or an HF filtration device.

[0030] In any of the above technical solutions, the first air inlet area is communicated with outdoor fresh air; or, the first air inlet area is communicated with indoor air.

[0031] The first air inlet area can receive outdoor fresh air. The first air inlet area can be communicated with outdoor fresh air through a fresh air pipe, introducing the outdoor fresh air into the air duct and blowing it out from the air outlet, thereby improving the indoor air quality.

[0032] In any of the above technical solutions, the wind wheel is arranged corresponding to the first air inlet area and the second air inlet area, and the heat exchanger can move between a first position covering the first air inlet area and a second position covering the second air inlet area.

[0033] The wind wheel is arranged corresponding to the first air inlet area and the second air inlet area, that is, the wind wheel at least partially covers the first air inlet area and at least partially covers the second air inlet area. The wind wheel is stationary relative to the housing, and the heat exchanger moves relative to the housing, specifically between the first position and the second position. At the first position, the wind wheel sucks in natural wind from the second air inlet area and non-natural wind from the first air inlet area, mixes them inside the wind wheel, and then blows them out from the air outlet; at the second position, the wind wheel sucks in non-natural wind from the second air inlet area and natural wind from the first air inlet area, mixes them inside the wind wheel, and then blows them out from the air outlet; the heat exchanger slides between the first position and the second position relative to the wind wheel to adjust the mixed air sucked by the wind wheel.

[0034] During the movement of the heat exchanger relative to the wind wheel, the wind wheel sucks in non-natural wind and natural wind simultaneously, mixes them inside the wind wheel to obtain mixed air, and improves the comfort of the air blown out by the air conditioner.

[0035] In any of the above technical solutions, a wind guiding wall is fixedly connected to the housing. The wind guiding wall encloses an air duct. The wind wheel is located inside the air duct. An air outlet is provided on the housing. The first end of the air duct is communicated with both the first air inlet area and the second air inlet area, and the second end of the air duct is communicated with the air outlet.

[0036] The wind guiding wall is fixed to the housing, that is, it is stationary relative to the housing. The wind guiding wall can communicate the first air inlet area with the air outlet and the second air inlet area with the air outlet. The setting method of the air duct being stationary relative to the housing can reduce the complexity of the air conditioner, but it is necessary to ensure the length of the air duct in the direction from the first air inlet area to the second air inlet area to ensure that the air duct can communicate the first air inlet area with the air outlet and can also communicate the second air inlet area with the air outlet.

[0037] In any of the above technical solutions, a guiding structure is provided between one of the wind wheel and the heat exchanger and the housing to guide the movement of one of the wind wheel and the heat exchanger relative to the other.

[0038] Optionally, one of the wind wheel and the heat exchanger moves relative to the housing, and the other is stationary relative to the housing. By setting the guiding structure, it can guide the one that moves relative to the housing among the wind wheel and the heat exchanger not to deviate during the movement. It can be understood that both the wind wheel and the heat exchanger can also move relative to the housing. In this case, a guiding structure can be set between the wind wheel and the housing, and at the same time, a guiding structure can be set between the heat exchanger and the housing.

[0039] Taking the movement of the wind wheel relative to the housing as an example, a guiding structure is provided between the wind wheel and the housing. For example, a guiding portion is connected to the wind wheel, and a guiding mating portion is connected to the housing. The guiding portion cooperates with the guiding mating portion to guide the wind wheel to move relative to the heat exchanger between the first position and the second position. The guiding portion and the guiding mating portion cooperate to guide the wind wheel to reciprocate relative to the heat exchanger between the first position and the second position, playing a guiding role in the movement process of the wind wheel and avoiding the deviation of the track during the movement of the wind wheel relative to the heat exchanger. The guiding portion includes a guiding groove provided on the wind wheel, and the guiding mating portion includes a guiding column provided on the housing. The guiding column is arranged in the guiding groove and can slide relative to the guiding groove. Or, the guiding portion includes a guiding column provided on the wind wheel, and the guiding mating portion includes a guiding groove provided on the housing. The guiding column is arranged in the guiding groove and can slide relative to the guiding groove.

[0040] In any of the above technical solutions, the air conditioner includes: a second driving device connected to one of the wind wheel and the heat exchanger for driving one of the wind wheel and the heat exchanger to move relative to the other.

[0041] The driving mode of the movement of one of the wind wheel and the heat exchanger relative to the other can be mechanical driving or electric control driving. The mechanical driving mode can be a link mechanism, a sprocket chain mechanism, etc.; the electric control driving mode can be a driving mode of a motor plus a lead screw, or a driving mode of a motor and a gear transmission mechanism.

[0042] In any of the above technical solutions, the second driving device includes a motor, a gear is connected to the motor shaft of the motor, and a rack is connected to one of the wind wheel and the heat exchanger. The gear meshes with the rack; or, the second driving device includes a motor, one end of the motor shaft is connected to one end of a lead screw, a slider is provided at the other end of the lead screw, the lead screw is in threaded cooperation with the slider, and the slider is connected to one of the wind wheel and the heat exchanger.

[0043] The motor shaft of the motor rotates, driving the gear to rotate. The rotation of the gear drives the rack to move, so as to drive the wind wheel to move relative to the heat exchanger or drive the heat exchanger to move relative to the wind wheel through the rack. Further, the rack extends along the movement direction of the wind wheel relative to the heat exchanger.

[0044] To not change the structure of the wind wheel, the guiding portion can be arranged on the rack.

[0045] In any of the above technical solutions, the first air inlet region and the second air inlet region are communicated.

[0046] If there is a non-zero spacing between the first air inlet area and the second air inlet area, during the movement of the wind wheel relative to the heat exchanger, there will be a part on the wind wheel corresponding to this non-zero spacing, which will reduce the utilization rate of the wind wheel. Further, when the wind wheel moves between the first position and the second position relative to the heat exchanger, any part of the wind wheel corresponds to the first air inlet area or the second air inlet area, and there is no part that does not correspond to the air inlet area (the air inlet area includes the first air inlet area and the second air inlet area), improving the utilization rate of the wind wheel.

[0047] In any of the above technical solutions, the first air inlet area and the second air inlet area are arranged in sequence along the length direction of the housing, and the wind wheel slides between the first position and the second position relative to the heat exchanger along the length direction of the housing.

[0048] The first air inlet area and the second air inlet area are arranged in sequence along the length direction of the housing, and the wind wheel can move along the length direction of the housing, that is, the wind wheel can move relative to the heat exchanger in a straight line direction. The connection line between the first position and the second position is parallel to the length direction of the housing.

[0049] Further, the length direction of the heat exchanger and the length direction of the wind wheel are both parallel to the length direction of the housing.

[0050] The air conditioner can be a wall-mounted air conditioner or a cabinet air conditioner. For a wall-mounted air conditioner, if the length direction of the housing is the left-right direction, the wind wheel moves relative to the heat exchanger in the left-right direction; for a cabinet air conditioner, if the length direction of the housing is the up-down direction, the wind wheel moves relative to the heat exchanger in the up-down direction.

[0051] In any of the above technical solutions, the length of the heat exchanger is less than the sum of the lengths of the first air inlet area and the second air inlet area, so that the heat exchanger cannot completely cover the first air inlet area and the second air inlet area, and further enables the air conditioner to blow out mixed air.

[0052] In any of the above technical solutions, the first air inlet area and the second air inlet area are arranged in sequence along the circumferential direction of the housing, and the wind wheel slides between the first position and the second position relative to the heat exchanger along the circumferential direction of the housing or in a straight line direction.

[0053] The first air inlet area and the second air inlet area are arranged along the circumferential direction of the housing. To achieve the effect of mixed air, the wind wheel moves in a straight line or moves in an arc relative to the heat exchanger along the circumferential direction of the housing.

[0054] It can be understood that the first air inlet area and the second air inlet area can be arranged in sequence along the length direction or the circumferential direction of the housing, or there can be other arrangement methods. When it is other arrangement methods, it is necessary to meet the requirement that the air conditioner can blow out mixed air through the relative movement between the heat exchanger and the wind wheel.

Detailed implementation manners

[0082] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0083] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0084] Next, refer to the attached Figures 1 to 23 Describe an air conditioner according to some embodiments of the present invention. The air conditioner may be a wall-mounted air conditioner (hanging air conditioner) or a floor-standing air conditioner. In the accompanying drawings, the wall-mounted air conditioner is taken as an example for illustration.

[0085] As Figure 1 and Figure 7 shown, an air conditioner according to some embodiments of the present invention includes: a housing 10 that defines an installation space 11. An air inlet is provided on the housing 10. The air inlet includes a first air inlet area 151 and a second air inlet area 152; a heat exchanger 4 and a blower wheel 5, both located in the installation space 11. The heat exchanger 4 does not completely cover the first air inlet area 151 and the second air inlet area 152. There is relative movement between the heat exchanger 4 and the blower wheel 5, and the blower wheel 5 has a preset position. At the preset position, along the length direction of the air inlet, part of the blower wheel 5 covers the heat exchanger 4, and part of the blower wheel 5 covers at least part of the area in the first air inlet area 151 and the second air inlet area 152 that is not covered by the heat exchanger 4.

[0086] The air conditioner 100 provided by the above embodiments of the present invention has, at a preset position, a part of the impeller 5 (named the first part of the impeller for convenience of description) covering the heat exchanger 4, that is, the first part of the impeller is correspondingly arranged with the heat exchanger 4, and the orthographic projection of the first part of the impeller on the heat exchanger 4 is not zero. A part of the impeller 5 (named the second part of the impeller for convenience of description) covers all or part of the areas in the first air inlet area 151 and the second air inlet area 152 that are not covered by the heat exchanger 4, that is, the second part of the impeller is correspondingly arranged with all or part of the areas in the first air inlet area 151 and the second air inlet area 152 that are not covered by the heat exchanger 4, and the orthographic projection of the second part of the impeller on the areas in the first air inlet area 151 and the second air inlet area 152 that are not covered by the heat exchanger 4 is not zero. At the preset position, the impeller 5 sucks air from the first air inlet area 151 and the second air inlet area 152. Specifically, the air entering through the first air inlet area 151 and the second air inlet area 152 covered by the heat exchanger 4 is non-natural air, and the air entering through the first air inlet area 151 and the second air inlet area 152 not covered by the heat exchanger 4 is normal temperature air (or natural air). The non-natural air and the natural air are mixed in the impeller 5 to obtain mixed air, improving the comfort of the air blown out by the air conditioner 100.

[0087] In this application, the relative movement between the driving impeller 5 and the heat exchanger 4 is used to blow out the mixed air. The structure is simple, the cost is low, and by controlling the relative position between the impeller 5 and the heat exchanger 4, the ratio of non-natural air to natural air can be changed, achieving a stepless mixing effect. The mixing effect is good and the mixing degree is easy to adjust.

[0088] Embodiment 1:

[0089] An air conditioner 100 includes: a housing 10 that defines an installation space 11, and the housing 10 is provided with a first air inlet area 151 and a second air inlet area 152; a heat exchanger 4 located in the installation space 11 and correspondingly arranged with the first air inlet area 151; and an impeller 5 located in the installation space 11 and capable of moving relative to the heat exchanger 4 between a first position covering the first air inlet area 151 and a second position covering the second air inlet area 152. That is, at the first position, the impeller 5 is correspondingly arranged with the first air inlet area, and the area of the orthographic projection of the impeller on the first air inlet area is not zero. At the second position, the impeller 5 is correspondingly arranged with the second air inlet area, and the area of the orthographic projection of the impeller on the second air inlet area is not zero. And the preset position is between the first position and the second position. That is, at the first position, at least part of the impeller 5 corresponds to the first air inlet area 151, at the second position, at least part of the impeller 5 corresponds to the second air inlet area 152, and at the preset position, part of the impeller 5 corresponds to part of the first air inlet area 151 and part corresponds to the second air inlet area 152.

[0090] The air conditioner 100 provided in the above embodiments of the present invention has the heat exchanger 4 disposed corresponding to the first air inlet area 151, which means that the air flowing into the first air inlet area 151 needs to pass through the heat exchanger 4 before flowing out through the air duct 12 and the air outlet 14. The impeller 5 corresponds to the first air inlet area 151, which means that under the action of the impeller 5, air enters the air duct 12 from the first air inlet area 151 and flows out through the air outlet 14; the impeller 5 corresponds to the second air inlet area 152, which means that under the action of the impeller 5, air enters the air duct 12 from the second air inlet area 152 and flows out through the air outlet 14; the impeller 5 at least partially corresponding to the first air inlet area 151 means that the impeller 5 is partially corresponding to the first air inlet area 151 or is completely disposed corresponding to the first air inlet area 151; the impeller 5 at least partially corresponding to the second air inlet area 152 means that the impeller 5 is partially corresponding to the second air inlet area 152 or is completely disposed corresponding to the second air inlet area 152. Further, the length of the heat exchanger is not less than the length of the first air inlet area. It can be understood that the length of the heat exchanger can also be less than the length of the first air inlet area. The orthographic projection of the heat exchanger on the first air inlet area is entirely located within the first air inlet area or, the orthographic projection of the heat exchanger on the first air inlet area partially extends beyond the range of the first air inlet area.

[0091] The heat exchanger 4 is disposed corresponding to the first air inlet area 151, and the impeller 5 can move between a first position and a second position relative to the heat exchanger 4, as Figure 3 shown. In this way, in the first position, at least part of the air inhaled by the impeller 5 is non-natural air that sequentially passes through the first air inlet area 151 and the heat exchanger 4, as Figure 9 shown. In the second position, at least part of the air inhaled by the impeller 5 is normal-temperature air (or natural air) from the second air inlet area 152 and does not pass through the heat exchanger. At a preset position, the impeller 5 is partially corresponding to the first air inlet area 151 and partially corresponding to the second air inlet area 152. Thus, the impeller 5 can simultaneously inhale non-natural air passing through the heat exchanger 4 from the first air inlet area 151 and natural air from the second air inlet area 152, and mix them inside the impeller 5 to obtain mixed air. The impeller 5 slides between the first position and the second position relative to the heat exchanger 4 and passes through the preset position during the sliding process, which can enable the impeller 5 to simultaneously inhale non-natural air and natural air, mix them inside the impeller 5, and obtain mixed air, improving the comfort of the air blown out by the air conditioner 100.

[0092] In the present application, by driving the impeller 5 to move relative to the heat exchanger 4 to change the relative position between the impeller and the heat exchanger, thereby changing the type of air inhaled by the impeller (natural air or non-natural air) and blowing out mixed air, the structure is simple, the cost is low, and by controlling the movement position of the impeller 5 relative to the heat exchanger 4, the ratio of non-natural air to natural air can be changed, achieving a stepless mixing effect, with good mixing effect and easy adjustment of the mixing degree.

[0093] AsFigure 13 and Figure 14 As shown in Figure 14 , the housing 10 includes a chassis 17 and a front frame 15. The chassis 17 and the front frame 15 define an installation space 11. The front frame 15 includes a top plate located at the top of the air conditioner 100 and a panel 16 located at the front of the air conditioner 100. At least one of the first air inlet area 151 and the second air inlet area 152 can be arranged at the top or the back of the air conditioner 100.

[0094] In the above embodiment, at the first position, the impeller 5 corresponds exactly to the first air inlet area 151. Further, the lengthwise projection of the impeller on the first air inlet area does not exceed the first air inlet area.

[0095] At the first position, the impeller 5 is arranged corresponding exactly to the first air inlet area 151. At this time, the cooling or heating effect of the air conditioner 100 is the strongest, thus improving the utilization rate of the heat exchanger 4. At the second position, the impeller 5 partially corresponds to the first air inlet area 151 and partially corresponds to the second air inlet area 152. During the movement of the impeller 5 relative to the heat exchanger 4, there are multiple preset positions.

[0096] In some embodiments, as Figure 1 shown, the first air inlet area 151 and the second air inlet area 152 are connected and communicated.

[0097] If there is a non-zero spacing between the first air inlet area 151 and the second air inlet area 152, that is, the first air inlet area and the second air inlet area are arranged at intervals, and there is a part of the housing between them. During the movement of the impeller 5 relative to the heat exchanger 4, there will be a part of the impeller 5 corresponding to this non-zero spacing, which will reduce the utilization rate of the impeller 5. Further, when the impeller 5 moves between the first position and the second position relative to the heat exchanger 4, any part of the impeller 5 corresponds to the first air inlet area 151 or the second air inlet area 152, and there is no part that does not correspond to the air inlet area (the air inlet area includes the first air inlet area 151 and the second air inlet area 152), improving the utilization rate of the impeller 5.

[0098] The first air inlet area and the second air inlet area are in a grid shape, thus defining a grid-shaped air inlet area. The shape and size of the first air inlet area and the second air inlet area can be flexibly set and are not limited here.

[0099] In some embodiments, as Figure 2 shown, the first air inlet area 151 and the second air inlet area 152 are arranged in sequence along the length direction of the housing 10 (i.e., Figure 2 the length direction of the heat exchanger in Figure 2 ), and the impeller 5 moves between the first position and the second position relative to the heat exchanger 4 along the length direction of the housing 10.

[0100] To ensure that the heat exchanger 4 cannot completely cover the first air inlet area 151 and the second air inlet area 152, and to ensure that the air conditioner 100 can blow out mixed air, the length direction of the heat exchanger 4 can be made consistent with the length direction of the housing 10, and the length of the heat exchanger 4 is less than the sum of the lengths of the first air inlet area 151 and the second air inlet area 152. It can be understood that to ensure that the heat exchanger 4 cannot completely cover the first air inlet area 151 and the second air inlet area 152, and to ensure that the air conditioner 100 can blow out mixed air, other means can also be adopted.

[0101] The first air inlet area 151 and the second air inlet area 152 are arranged in sequence along the length direction of the housing 10, and the impeller 5 can move along the length direction of the housing 10, that is, the impeller 5 can move relative to the heat exchanger 4 in a straight line direction. The connection line between the first position and the second position is parallel to the length direction of the housing 10.

[0102] Furthermore, the length direction of the heat exchanger 4 and the length direction of the impeller 5 are both parallel to the length direction of the housing 10.

[0103] The air conditioner 100 can be a wall-mounted air conditioner 100 or a floor-standing unit. For the wall-mounted air conditioner 100, if the length direction of the housing 10 is the left-right direction, the impeller 5 moves relative to the heat exchanger 4 in the left-right direction; for the floor-standing unit, if the length direction of the housing 10 is the up-down direction, the impeller 5 moves relative to the heat exchanger 4 in the up-down direction.

[0104] As Figure 7 and Figure 8 shown, the heat exchanger 4 is an evaporator, and a second air inlet area 152 is left on the side of the evaporator. The impeller 5, the first driving device 6 and its installation structure (including bearings and bearing seats) can slide in the entire air duct 12. When the impeller 5 is completely placed below the evaporator, the refrigeration effect is the strongest; during the process of the impeller 5 moving from one end (the first position) of the evaporator to the extreme position (the second position), the heat exchange air inlet (non-natural air) and the normal temperature air (natural air) inlet change, and stepless mixed air can be realized.

[0105] In some embodiments, a guiding structure is provided between the impeller 5 and the housing 10. For example, a guiding portion is connected to the impeller 5, and a guiding and cooperating portion is connected to the housing 10. The guiding portion cooperates with the guiding and cooperating portion to guide the impeller 5 to move between the first position and the second position relative to the heat exchanger 4.

[0106] The guiding portion cooperates with the guiding and cooperating portion to guide the impeller 5 to reciprocate between the first position and the second position relative to the heat exchanger 4, playing a guiding role in the movement process of the impeller 5 and avoiding the deviation of the track during the movement of the impeller 5 relative to the heat exchanger 4.

[0107] The guiding part includes guiding grooves provided on the wind wheel 5, and the guiding and mating part includes guiding columns provided on the housing 10. The guiding columns are arranged in the guiding grooves and can slide relative to the guiding grooves. Alternatively, the guiding part includes guiding columns provided on the wind wheel 5, and the guiding and mating part includes guiding grooves provided on the housing 10. The guiding columns are arranged in the guiding grooves and can slide relative to the guiding grooves.

[0108] In some embodiments, the air conditioner 100 includes: a second driving device, which is connected to the wind wheel 5 and is used to drive the wind wheel 5 to move relative to the heat exchanger 4 between a first position and a second position.

[0109] The driving mode of the wind wheel 5 moving relative to the heat exchanger 4 can be mechanical driving or electric control driving. The mechanical driving mode can be a link mechanism, a sprocket and chain mechanism, etc.; the electric control driving mode can be a driving mode of a motor plus a lead screw, or a driving mode of a motor and a gear transmission mechanism.

[0110] In some embodiments, the second driving device includes a motor. A gear is connected to the motor shaft of the motor, and a rack is connected to the wind wheel 5. The gear meshes with the rack.

[0111] The motor shaft of the motor rotates, driving the gear to rotate. The rotation of the gear drives the rack to move, thereby driving the wind wheel 5 to move relative to the heat exchanger 4 through the rack. Further, the rack extends along the movement direction of the wind wheel 5 relative to the heat exchanger 4.

[0112] To not change the structure of the wind wheel 5, the guiding part can be arranged on the rack.

[0113] In some embodiments, the air conditioner 100 includes: a first driving device 6, which is located in the installation space 11 and is connected to the wind wheel 5 and is used to drive the wind wheel 5 to rotate around its own axis. The first driving device 6 moves with the wind wheel 5 relative to the heat exchanger 4.

[0114] The first driving device 6 moves with the wind wheel 5 to ensure that at the first position, the second position, and any position between the first position and the second position, the first driving device 6 can drive the wind wheel 5 to rotate around the axis of the wind wheel 5. The first driving device 6 is connected to the wind wheel 5 and drives the wind wheel 5 to rotate along the axis direction of the wind wheel 5, thereby sucking the air flow in the first air inlet area 151 and / or the second air inlet area 152 into the air duct 12 and flowing out from the air outlet 14. The first driving device 6 can be a motor.

[0115] During the movement of the wind wheel 5 relative to the heat exchanger 4, the second driving device simultaneously drives the wind wheel 5 and the first driving device 6 to move relative to the heat exchanger 4 between the first position and the second position.

[0116] In some embodiments, such as Figure 3As shown, the air conditioner 100 includes a bearing assembly 7. The bearing assembly 7 includes a bearing and a bearing housing. The bearing and the bearing housing are supported between the impeller 5 and the housing 10, for example, supported between the impeller 5 and the chassis, and move with the impeller 5 relative to the heat exchanger 4.

[0117] Both the bearing and the bearing housing are located within the installation space 11. The inner ring of the bearing is fixedly connected to the impeller 5, the outer ring of the bearing is connected to the bearing housing, and the bearing housing is disposed on the housing 10, which not only realizes the installation of the impeller 5 on the housing 10 but also realizes the rotation of the impeller 5 relative to the housing 10 about the axis of the impeller 5 itself. The bearing and the bearing housing move with the impeller 5 relative to the heat exchanger 4, so that in the first position, the second position, and any position between the first position and the second position of the impeller 5, the bearing and the bearing housing can well support the impeller 5.

[0118] Optionally, the first driving device 6 and the bearing assembly 7 are respectively located at both ends of the impeller 5 in the length direction. For example, when the first air inlet area 151 and the second air inlet area 152 are arranged along the length direction of the impeller 5, the bearing assembly 7 is arranged close to the second air inlet area 152.

[0119] In some embodiments, as Figure 5 , Figure 6 , Figure 11 and Figure 12 shown, a wind guiding wall 13 is provided inside the housing 10. The wind guiding wall 13 encloses an air duct 12, the impeller 5 is located within the air duct 12, and an air outlet 14 is provided on the housing 10. The air duct 12 is used to connect at least one of the first air inlet area 151 and the second air inlet area 152 corresponding to the impeller 5 with the air outlet 14.

[0120] "The air duct 12 is used to connect at least one of the first air inlet area 151 and the second air inlet area 152 corresponding to the impeller 5 with the air outlet 14" means that when the impeller 5 corresponds to the first air inlet area 151, the air duct 12 can connect the first air inlet area 151 and the air outlet 14; when the impeller 5 corresponds to the second air inlet area 152, the air duct 12 can connect the second air inlet area 152 and the air outlet 14; when the impeller 5 corresponds to both the first air inlet area 151 and the second air inlet area 152, the air duct 12 can connect the first air inlet area 151 and the air outlet 14, and can also connect the second air inlet area 152 and the air outlet 14.

[0121] Through the arrangement of the air duct 12, under the action of the impeller 5, the air flow entering the air duct 12 from at least one of the first air inlet area 151 and the second air inlet area 152 can flow out from the air outlet 14.

[0122] In some embodiments, as Figure 5 , Figure 6 , Figure 11 and Figure 12As shown, the air guide wall 13 is fixed to the housing 10. The air duct 12 is in communication with both the first air inlet area 151 and the second air inlet area 152. The air wheel 5 moves relative to the air duct 12 between a first position and a second position.

[0123] The air guide wall 13 is fixed to the housing 10, so that the air duct 12 is also stationary relative to the housing 10. That is, when the air wheel 5 moves relative to the heat exchanger 4, the air wheel 5 also moves relative to the air duct 12. The arrangement in which the air duct 12 is stationary relative to the housing 10 can reduce the complexity of the air conditioner 100, but it is necessary to ensure the length of the air duct 12 in the direction from the first air inlet area 151 to the second air inlet area 152, so as to ensure that the air duct 12 can communicate with the first air inlet area 151 and the air outlet 14, and can also communicate with the second air inlet area 152 and the air outlet 14.

[0124] The first air inlet area 151 and the second air inlet area 152 can be directly air inlet, or a purification device can be added to form a purification effect. Optionally, the air conditioner 100 includes: a purification device, and the purification device is arranged at the second air inlet area 152.

[0125] In the related art, the purification device is arranged on the heat exchanger 4 and corresponds to the first air inlet area 151. The air flow entering the installation space 11 from the first air inlet area 151 needs to pass through the purification device and the heat exchanger 4, resulting in a large air inlet resistance. In this application, the purification device is arranged at the second air inlet area 152, that is, the purification device corresponds to the second air inlet area 152. The air flow entering from the second air inlet area 152 passes through the purification device, then passes through the air wheel 5, and then flows out from the air wheel 5 to the air outlet 14, which not only realizes the purification of the air flow but also reduces the air inlet resistance.

[0126] The purification device can be a HEPA filtration device (high-efficiency air filtration device or high-efficiency air filter or high-efficiency air filter mesh) or an HF filtration device.

[0127] In some embodiments, the first air inlet area 151 is in communication with outdoor fresh air; or, the first air inlet area 151 is in communication with indoor air.

[0128] The first air inlet area 151 can receive outdoor fresh air. The first air inlet area 151 can be connected to outdoor fresh air through a fresh air pipe, introduce the outdoor fresh air into the air duct 12, and blow it out from the air outlet 14, thereby improving the indoor air quality.

[0129] Embodiment 2:

[0130] The difference from Embodiment 1 is that the first air inlet area 151 and the second air inlet area 152 are arranged in sequence along the circumferential direction of the housing 10, and the air wheel 5 slides between a first position and a second position relative to the heat exchanger 4 along the circumferential direction of the housing 10 or in a straight line direction.

[0131] The first air inlet area 151 and the second air inlet area 152 are arranged along the circumferential direction of the housing 10. To achieve the effect of mixed air, the wind wheel 5 moves linearly or moves in an arc relative to the heat exchanger 4 along the circumferential direction of the housing 10.

[0132] It can be understood that the first air inlet area 151 and the second air inlet area 152 can be arranged in sequence along the length direction or the circumferential direction of the housing 10, or there can be other arrangement methods. When it is other arrangement methods, the selection of the movement form (including the movement direction and trajectory) of the heat exchanger 4 should meet that at the first position, at least part of the wind wheel 5 corresponds to the first air inlet area 151, at the second position, at least part of the wind wheel 5 corresponds to the second air inlet area 152, and there is a preset position where part of the wind wheel 5 corresponds to the first air inlet area 151 and part corresponds to the second air inlet area 152.

[0133] Embodiment Three:

[0134] The difference from Embodiment One and Embodiment Two is that the air guide wall 13 is connected to the wind wheel 5 and moves with the wind wheel 5 relative to the heat exchanger 4.

[0135] The air guide wall 13 and the wind wheel 5 can be fixedly connected. In this way, the air guide wall 13 moves with the wind wheel 5 relative to the heat exchanger 4, so that the air duct 12 moves with the wind wheel 5 relative to the heat exchanger 4. The second driving device is connected to the air guide wall 13 or the wind wheel 5 to drive the wind wheel 5 and the air guide wall 13 to move between the first position and the second position relative to the heat exchanger 4. For example, the second driving device includes a motor, a gear is connected to the motor shaft, and a rack meshing with the gear is connected to the air guide wall 13 or the wind wheel 5, which realizes the driving of the second driving device on the air guide wall 13 and the wind wheel 5.

[0136] Alternatively, the air guide wall 13 and the wind wheel 5 are movably connected or not connected, and the second driving device is used to drive the wind wheel 5 to move between the first position and the second position relative to the heat exchanger 4. The air conditioner 100 further includes a third driving device, and the third driving device is connected to the air guide wall 13 and is used to drive the air guide wall 13 to move between the first position and the second position with the wind wheel 5 relative to the heat exchanger 4.

[0137] Embodiment Four:

[0138] The difference from Embodiment One, Embodiment Two and Embodiment Three is that the wind wheel 5 is arranged corresponding to the first air inlet area 151 and the second air inlet area 152, that is, the areas of the orthographic projections of the wind wheel on the first air inlet area and the second air inlet area are both non-zero, and the heat exchanger 4 can move between the first position covering the first air inlet area 151 and the second position covering the second air inlet area 152, that is, at the first position, the orthographic projection of the heat exchanger on the first air inlet area is non-zero, and at the second position, the orthographic projection of the heat exchanger on the second air inlet area is non-zero. Such as Figure 15 、16 and Figure 20 As shown in Figure 20 , the first air inlet area 151 and the second air inlet area 152 are arranged along the length direction of the housing 10. The length direction of the wind wheel 5 and the length direction of the heat exchanger 4 are both the same as the length direction of the housing 10. The length of the wind wheel 5 is greater than the length of the heat exchanger 4. Further, the length of the wind wheel 5 is the same as the sum of the lengths of the first air inlet area 151 and the second air inlet area 152, so that the wind wheel 5 can completely cover the first air inlet area 151 and the second air inlet area 152 in the length direction. The length of the heat exchanger 4 is less than the sum of the lengths of the first air inlet area 151 and the second air inlet area 152, so that the heat exchanger 4 cannot completely cover the first air inlet area 151 and the second air inlet area 152 in the length direction.

[0139] The wind wheel is arranged corresponding to the first air inlet area and the second air inlet area, that is, the wind wheel at least partially covers the first air inlet area and at least partially covers the second air inlet area. The wind wheel is stationary relative to the housing, and the heat exchanger moves relative to the housing and specifically moves between a first position and a second position. At the first position, the wind wheel sucks in natural wind from the second air inlet area and non-natural wind from the first air inlet area, mixes them inside the wind wheel and blows them out from the air outlet; at the second position, the wind wheel sucks in non-natural wind from the second air inlet area and natural wind from the first air inlet area, mixes them inside the wind wheel and blows them out from the air outlet; the heat exchanger slides between the first position and the second position relative to the wind wheel to adjust the mixed wind sucked in by the wind wheel.

[0140] As Figure 15 and Figure 16 shown, when the heat exchanger is in the first position, non-natural wind enters at the first air inlet area and natural wind enters at the second air inlet area. As shown in Figure 21 and 22 , the first air inlet area 151 and the second air inlet area 152 are arranged along the length direction of the housing 10. The heat exchanger 4 reciprocates along the X direction relative to the wind wheel 5. The heat exchanger 4 moves to a position between the first position and the second position. The heat exchanger does not correspond to the first air inlet area at the Q2 position, that is, it does not cover the first air inlet area at the Q2 position. Natural wind is sucked in by the wind wheel at the Q2 position. The heat exchanger does not correspond to the second air inlet area at the Q3 position, that is, it does not cover the first air inlet area at the Q3 position. Natural wind is sucked in by the wind wheel at the Q3 position. The heat exchanger corresponds to the air inlet area (including the first air inlet area and / or the second air inlet area) at the Q1 position, that is, it covers the air inlet area at the Q1 position. Non-natural wind is sucked in by the wind wheel at the Q1 position. As shown in Figure 23 , the wind wheel sucks in natural wind from Z1 and Z3 and non-natural wind from Z2. Figure 21 and 22 shown, when the heat exchanger is in the first position, non-natural wind enters at the first air inlet area and natural wind enters at the second air inlet area. As shown in Figure 21 and 22 , the first air inlet area 151 and the second air inlet area 152 are arranged along the length direction of the housing 10. The heat exchanger 4 reciprocates along the X direction relative to the wind wheel 5. The heat exchanger 4 moves to a position between the first position and the second position. The heat exchanger does not correspond to the first air inlet area at the Q2 position, that is, it does not cover the first air inlet area at the Q2 position. Natural wind is sucked in by the wind wheel at the Q2 position. The heat exchanger does not correspond to the second air inlet area at the Q3 position, that is, it does not cover the first air inlet area at the Q3 position. Natural wind is sucked in by the wind wheel at the Q3 position. The heat exchanger corresponds to the air inlet area (including the first air inlet area and / or the second air inlet area) at the Q1 position, that is, it covers the air inlet area at the Q1 position. Non-natural wind is sucked in by the wind wheel at the Q1 position. As shown in Figure 23 , the wind wheel sucks in natural wind from Z1 and Z3 and non-natural wind from Z2. Figure 23 shown, the wind wheel sucks in natural wind from Z1 and Z3 and non-natural wind from Z2.

[0141] Further, a wind guiding wall 13 is fixedly connected to the housing 10. The wind guiding wall 13 encloses an air duct 12. The wind wheel 5 is located inside the air duct 12. An air outlet 14 is provided on the housing 10. The first end of the air duct 12 is in communication with both the first air inlet area 151 and the second air inlet area 152, and the second end of the air duct is in communication with the air outlet 14.

[0142] The wind guiding wall is fixed to the housing, that is, stationary relative to the housing. The wind guiding wall is relatively long so as to be able to communicate the first air inlet area with the air outlet and the second air inlet area with the air outlet. The setting method in which the air duct is stationary relative to the housing can reduce the complexity of the air conditioner, but it is necessary to ensure the length of the air duct in the direction from the first air inlet area to the second air inlet area to ensure that the air duct can communicate the first air inlet area with the air outlet and can communicate the second air inlet area with the air outlet.

[0143] Further, a guiding structure is provided between the heat exchanger and the housing to guide the movement of the heat exchanger relative to the housing and the wind wheel.

[0144] Further, the second driving device is connected to the heat exchanger 4 and is used to drive the movement of the heat exchanger 4 relative to the wind wheel 5.

[0145] Further, the second driving device includes a motor. A gear is connected to the motor shaft of the motor. A rack is connected to the heat exchanger 4. The gear meshes with the rack; alternatively, the second driving device includes a motor. One end of a lead screw is connected to the motor shaft of the motor. A slider is provided at the other end of the lead screw. The lead screw is in threaded cooperation with the slider, and the slider is connected to the heat exchanger 4.

[0146] In summary, for the air conditioner 100 provided by the embodiment of the present invention, by providing the second air inlet area 152 on the side of the evaporator and then moving the wind wheel 5 relative to the evaporator, the wind wheel 5 can simultaneously suck in normal temperature air and refrigerated air and mix them inside the wind wheel 5. At the same time, by changing the relative position between the wind wheel 5 and the evaporator, the ratio of the normal temperature air to the refrigerated air can be steplessly adjusted, so as to achieve a stepless air mixing effect. Secondly, a purification device can be added at the second air inlet area 152 to play a purification role and realize air purification with a small resistance. Therefore, the air conditioner 100 of the present application can achieve stepless adjustment of the mixed air, and has a simple structure, is easy to disassemble and assemble, and is easy to operate.
