Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air handling equipment technology, specifically referring to an air conditioner. Background Technology

[0002] In related technologies, the air deflector of an air conditioner is rotatably located at the air outlet. During rotation, it is easy to interfere with the heat exchanger. Therefore, sufficient space needs to be reserved inside the air conditioner casing, resulting in an excessively large air conditioner body size. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an air conditioner that is advantageous in reducing the size of the air conditioner body.

[0004] This application provides an air conditioner, comprising: a housing, the housing having an air duct, a side air outlet, and a bottom air outlet, the side air outlet being able to communicate with the air duct to form a first air outlet channel, and the bottom air outlet being able to communicate with the air duct to form a second air outlet channel; an air guiding mechanism, including a first air guide plate rotatably disposed at the side air outlet and a second air guide plate rotatably disposed at the bottom air outlet, the first air guide plate having a first rotation axis, and the second air guide plate having a second rotation axis; wherein, the first rotation axis is located between the two ends of the side air outlet in the width direction; and / or, the second rotation axis is located between the two ends of the bottom air outlet in the width direction; a heat exchanger, located within the air duct, the vertical plane passing through the first rotation axis is denoted as a reference plane, the part with the smallest distance between the heat exchanger and the reference plane is denoted as a limit part, and the plane passing through the center of the limit part and extending along the air outlet direction of the side air outlet is denoted as a reference plane, the first rotation axis being offset from the reference plane.

[0005] The air conditioner provided in this application embodiment, by changing the position of the rotation axis of the first air guide plate and / or the second air guide plate, allows only a portion of the first air guide plate to turn into the air duct during rotation. This helps reduce the risk of interference between the air guide plate and the heat exchanger, thereby reducing the reserved distance between the heat exchanger and the air guide plate, reducing the unit size, and facilitating air conditioner installation. Furthermore, compared to a scheme where the first rotation axis of the first air guide plate is coplanar with the reference plane, a scheme where the first rotation axis of the first air guide plate is offset from the reference plane increases the horizontal distance between the first rotation axis and the heat exchanger. This allows the first air guide plate to make better use of the space above and below the limit section of the heat exchanger for rotation, thus expanding the rotation range of the first air guide plate.

[0006] Based on the above technical solution, the following improvements can be made to this application.

[0007] In one exemplary embodiment, the width of the side vent is greater than or equal to the width of the downwind vent.

[0009] In one exemplary embodiment, the first rotation axis is located at one end or between the two ends of the first air guide plate in the width direction; and / or, the second rotation axis is located at one end or between the two ends of the second air guide plate in the width direction.

[0010] In one exemplary embodiment, the heat exchanger is a straight-flow heat exchanger or a bent-flow heat exchanger.

[0011] In an exemplary embodiment, the limiting portion is a linear structure parallel to the reference plane, and the center of the limiting portion is the center of the length direction of the linear structure.

[0018] in, Figures 14 to 16 The arrows in the diagram indicate the direction of airflow. Detailed Implementation

[0019] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0020] In related technologies, the main reason for the excessively large size of the air conditioner unit is that the rotation axis of the air guide plate is located at the end of the width direction of the air guide plate and at the end of the width direction of the air outlet. Therefore, during the rotation of the air guide plate, almost the entire air guide plate turns into the air duct, occupying a large space inside the air duct and easily interfering with the heat exchanger. To avoid interference between the air guide plate and the heat exchanger, the distance between the heat exchanger and the air outlet needs to be increased to leave sufficient space for the rotation of the air guide plate, resulting in an excessively large air conditioner unit size. An excessively large unit size can also affect the installation of the air conditioner. For example, for ducted air conditioners and other air conditioners that need to be installed in the ceiling, an excessively large unit size (such as an excessively long or tall unit) will place higher demands on the ceiling, thus affecting the installation of the air conditioner.

[0021] Therefore, such as Figures 1 to 13 As shown in the figure, this application provides an air conditioner, including: a housing 1, a heat exchanger 3, and an air guide mechanism.

[0022] Among them, such as Figure 1 and Figure 4 As shown, the housing 1 is provided with an air duct 14, a side air vent 151, and a bottom air vent 152. The side air vent 151 can communicate with the air duct 14 to form a first air outlet channel, and the bottom air vent 152 can communicate with the air duct 14 to form a second air outlet channel. The side air vent 151 is usually arranged facing forward and can also be called a front air vent. Therefore, the first air outlet channel can discharge air forward, which is convenient for delivering cold air over long distances in cooling mode to avoid blowing directly on the user. The second air outlet channel can discharge air downward, which is convenient for warm air to sink downwards in heating mode to achieve a foot warming effect.

[0023] like Figure 1 and Figure 4 As shown, the air guiding mechanism includes a first air guide plate 21 rotatably disposed at a side air outlet 151 and a second air guide plate 22 rotatably disposed at a downwind outlet 152. The first air guide plate 21 can be used to control the opening and closing of the side air outlet 151, and the second air guide plate 22 can be used to control the opening and closing of the downwind outlet 152. The first air guide plate 21 has a first rotation axis 231, and the second air guide plate 22 has a second rotation axis 232.

[0024] Heat exchanger 3 is located inside air duct 14. For example... Figure 1 and Figure 9 As shown, the vertical plane passing through the first rotation axis 231 is designated as the reference plane 4, and the part with the smallest distance (horizontal distance) between the heat exchanger 3 and the reference plane 4 is designated as the limit part 31. The plane passing through the center of the limit part 31 and extending along the air outlet direction (horizontal forward direction) of the side air outlet 151 is designated as the reference plane 5. The reference plane 4 is a vertical plane. When the side air outlet 151 is the front air outlet, the distance between the heat exchanger 3 and the reference plane 4 is the horizontal distance between the front end of the heat exchanger 3 and the reference plane 4. The limit part 31 is the part of the front end of the heat exchanger 3 that is closest to the reference plane 4.

[0025] Among them, such as Figures 1 to 12 As shown, the first rotation axis 231 is located between the two ends (upper and lower ends) of the side air vent 151 in the width direction; and / or, the second rotation axis 232 is located between the two ends (front and rear ends) of the downwind vent 152 in the width direction, as shown. Figures 5 to 12 As shown.

[0026] like Figures 1 to 12 As shown, when the first rotation axis 231 is located between the two ends of the side air outlet 151 in the width direction, only part of the first air guide plate 21 will rotate into the air duct 14 during the rotation process, while the other part will rotate out of the air duct 14. This can reduce the space requirement of the first air guide plate 21 on the air duct 14 during the rotation process, which is conducive to avoiding interference between the first air guide plate 21 and the heat exchanger 3, and to reducing the reserved distance between the heat exchanger 3 and the side air outlet 151, thereby helping to reduce the length of the fuselage.

[0027] Similarly, such as Figures 5 to 12 As shown, when the second rotation axis 232 is located between the two ends of the side air outlet 151 in the width direction, only part of the second air guide plate 22 will rotate into the air duct 14 during the rotation process, while the other part will rotate out of the air duct 14. This can reduce the space requirement of the second air guide plate 22 on the air duct 14 during the rotation process, which is conducive to avoiding interference between the second air guide plate 22 and the heat exchanger 3, and to reducing the space reserved between the heat exchanger 3 and the lower air outlet 152, thereby helping to reduce the length and height of the body.

[0028] Therefore, the air conditioner provided in this application embodiment, by changing the position of the rotation axis of the first air guide plate 21 and / or the second air guide plate 22, can ensure that only a portion of the first air guide plate 21 and / or the second air guide plate 22 rotates into the air duct 14. This helps reduce the risk of interference between the air guide plate and the heat exchanger 3, thereby reducing the reserved distance between the heat exchanger 3 and the air guide plate, reducing the unit size, and facilitating air conditioner installation. Furthermore, compared to the scheme where the first rotation axis 231 of the first air guide plate 21 is coplanar with the reference plane 5, the scheme where the first rotation axis 231 of the first air guide plate 21 is offset from the reference plane 5 increases the horizontal distance between the first rotation axis 231 and the heat exchanger 3. This allows the first air guide plate 21 to utilize the space above and below the limit portion 31 of the heat exchanger 3 for rotation, thus expanding the rotation range of the first air guide plate 21.

[0029] In some exemplary embodiments, such as Figure 4 As shown, the width of the side vent 151 is greater than or equal to the width of the leeward vent 152. The width of the side vent 151 refers to the vertical distance between its two ends in the width direction. The width of the leeward vent 152 refers to the horizontal distance between its two ends in the width direction.

[0030] In other words, the width of the downwind vent 152 is less than or equal to the width of the side vent 151. This helps to reduce the width of the air outlet opening on the ceiling plate of the ceiling-mounted air conditioner, which is beneficial to optimizing the aesthetics of the decoration. It also takes into account the need for large air volume output over long distances indoors, which helps to improve the uniformity of indoor temperature.

[0031] In some exemplary embodiments, the first air guide plate 21 includes a plurality of sub-air guide plates (not shown) arranged side by side along the width direction of the side air vent 151. The rotation axis of at least one sub-air guide plate is located between the two ends of the side air vent 151 in the width direction and is offset from the reference plane 5, so that the first air guide plate 21 has at least one first rotation axis 231.

[0032] Compared to the integrated first air guide plate 21, the split first air guide plate 21 makes each sub-air guide plate narrower, requires less space for rotation, and has a lower risk of interference with the heat exchanger 3, thus helping to further reduce the body length.

[0033] In other embodiments, the second air guide plate 22 may also be composed of multiple sub-plates.

[0034] In some exemplary embodiments, the first rotation axis 231 is located at one end or between the two ends of the first air guide plate 21 in the width direction.

[0035] For the integrated first air guide plate 21, compared to the first rotation axis 231 being located at the end of the width direction of the first air guide plate 21, the first rotation axis 231 is located between the two ends of the width direction of the first air guide plate 21. This makes the first air guide plate 21 require less rotation space and reduces the risk of interference with the heat exchanger 3, thus facilitating a further reduction in the body length. Of course, the second rotation axis 231 can also be located at the end of the width direction of the first air guide plate 21.

[0036] For the split-type first air guide plate 21, since the width of a single sub-air guide plate is small, the first rotation axis 231 can also be located at the end of the width direction of the first air guide plate 21, or it can be located between the two ends of the width direction of the first air guide plate 21.

[0037] In some exemplary embodiments, the second rotation axis 232 is located at one end or between the two ends of the second air guide plate 22 in the width direction.

[0038] For the integrated second air guide plate 22, compared to the second rotation axis 232 being located at one end of the width direction of the second air guide plate 22, the second rotation axis 232 is located between the two ends of the width direction of the second air guide plate 22. This makes the second air guide plate 22 require less rotation space and reduces the risk of interference with the heat exchanger 3, thus facilitating a further reduction in the body length. Of course, the second rotation axis 232 can also be located at one end of the width direction of the second air guide plate 22.

[0039] For the split-type second air guide plate 22, since the width of a single sub-air guide plate is small, the second rotation axis 232 can also be located at the end of the width direction of the second air guide plate 22, or it can be located between the two ends of the width direction of the second air guide plate 22.

[0040] In some exemplary embodiments, the distance L between the limiting portion 31 and the reference surface 4 is in the range of 20mm to 100mm, such as 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc. Specifically, when the first air guide plate 21 is an integral structure, the distance between the limiting portion 31 and the reference surface 4 is greater than the distance between the limiting portion 31 and the reference surface 4 when the first air guide plate 21 is a split structure.

[0041] Through testing, it has been verified that the distance between the limit section 31 and the reference surface 4 is limited to the above-mentioned range, which can effectively reduce the risk of interference between the first air guide plate 21 and the heat exchanger 3, and keep the body size within a suitable range.

[0042] Of course, the distance between the limit section 31 and the reference surface 4 is not limited to the above range and can be adjusted as needed.

[0043] In some exemplary embodiments, the housing 1 includes a casing and an air outlet panel (not shown in the figure). The air outlet panel is detachably connected to the casing. The casing is provided with an air duct 14. A side air outlet 151 and a bottom air outlet 152 are provided on the air outlet panel. An air guiding mechanism is installed on the air outlet panel. The air outlet panel has a relatively large thickness and is provided with a hollow cavity so that the side walls of the cavity are provided with the side air outlet 151 and the bottom wall is provided with the bottom air outlet 152.

[0044] In this way, the air outlet panel and air guide mechanism can be used as components of an external air outlet module, which can be detachably connected to the housing. This simplifies the housing structure and allows for the integration of more components into the air outlet module, such as air guide vanes and linkage mechanisms, to further expand the range of air outlet direction adjustment.

[0045] In some other exemplary embodiments, the housing 1 includes a casing, which is provided with an air duct 14, a side air vent 151 and a down vent 152, and an air guiding mechanism is installed on the casing.

[0046] In other words, housing 1 does not include the air outlet panel, which makes the structure of housing 1 simpler and helps to reduce the cost of the air conditioner.

[0047] In some exemplary embodiments, the first rotation axis 231 is located between the two ends of the first air guide plate 21 in the width direction, and also between the two ends of the side air outlet 151 in the width direction, such as... Figures 1 to 12 As shown.

[0048] like Figures 5 to 12 As shown, the second rotation axis 232 is located between the two ends of the second air guide plate 22 in the width direction, and also between the two ends of the downdraft outlet 152 in the width direction. Alternatively, the second rotation axis 232 is located at one end of the second air guide plate 22 in the width direction, and also at one end of the downdraft outlet 152 in the width direction, as shown. Figures 1 to 4 As shown.

[0049] Compared to the second air guide plate 22, the first air guide plate 21 has a higher risk of interference with the heat exchanger 3 and a greater impact on the body size (body length). Therefore, adopting the above solution for the first air guide plate 21 has a greater beneficial impact on the body size.

[0050] The second air guide plate 22 can adopt a traditional scheme (i.e., the second rotation axis 232 is located at the end of the width direction of the second air guide plate 22 and at the end of the width direction of the downwind outlet 152), or it can adopt an improved scheme (i.e., the second rotation axis 232 is located between the two ends of the width direction of the second air guide plate 22 and between the two ends of the width direction of the downwind outlet 152).

[0051] In some exemplary embodiments, the heat exchanger 3 is a straight-flow heat exchanger 3 or a bent-flow heat exchanger 3.

[0052] When heat exchanger 3 is a straight-flow heat exchanger 3, the straight-flow heat exchanger 3 can be installed at an angle (e.g., Figure 15 As shown in the diagram, this arrangement allows for an increase in the heat exchange area of ​​the heat exchanger 3 while maintaining the same overall height, thereby improving heat exchange efficiency. Of course, the straight-line heat exchanger 3 can also be installed vertically, as shown in the diagram. Figure 14 As shown.

[0053] When heat exchanger 3 is a bent-type heat exchanger 3, the bent-type heat exchanger 3 can be an arc-shaped heat exchanger 3 (or a C-shaped heat exchanger 3, such as...). Figure 13 As shown), U-shaped heat exchanger 3 (as shown) Figure 16 (as shown) or multi-fold heat exchanger 3 (such as two-fold heat exchanger 3, three-fold heat exchanger 3, etc., as shown) Figures 1 to 12 (As shown). Among them, the arc-shaped heat exchanger 3 is a heat exchanger 3 with a longitudinal cross-section that is approximately arc-shaped, such as... Figure 13 As shown. The U-shaped heat exchanger 3 is a heat exchanger with a roughly U-shaped longitudinal cross-section, as shown... Figure 16 As shown. The multi-fold heat exchanger 3 has a longitudinal cross-section that is approximately multi-folded (e.g., a V-shape with the opening facing backwards, such as...). Figures 1 to 8 The heat exchanger 3 (shown) includes multiple interconnected sub-heat exchangers 3 with more than two folds. The multi-fold heat exchanger 3 can fully utilize the internal space of the air duct 14 to increase the heat exchange area of ​​the heat exchanger 3 and provides more space for the rotation of the air guide plate. Furthermore, for the multi-fold heat exchanger 3, the multiple sub-heat exchangers 3 are usually not symmetrical; adjacent sub-heat exchangers 3 may have inconsistent heights, inclinations, etc. Figures 9 to 12 As shown. Therefore, the multi-fold heat exchanger 3 typically has a distinct limiting section 31.

[0054] In some exemplary embodiments, the limiting portion 31 is a linear structure parallel to the reference plane 4, and the center of the limiting portion 31 is the center of the length direction of the linear structure.

[0055] For example: for a tilted, straight-line heat exchanger 3, such as Figure 15 As shown, its foremost end is typically a convex ridge extending along the length of the side air vent 151, therefore the limiting part 31 is a linear structure parallel to the side air vent 151. For the arc-shaped heat exchanger 3, as... Figure 13 As shown, its foremost point corresponds to a tangent extending along the length of the side air vent 151, therefore the limiting section 31 is a linear structure parallel to the side air vent 151. For the multi-fold heat exchanger 3, as... Figures 1 to 12 As shown, its front end is usually a convex ridge extending along the length of the side air vent 151, so the limit part 31 is a linear structure parallel to the side air vent 151.

[0056] When the limit section 31 is a linear structure, the center of the limit section 31 is the center of the length direction of the linear structure. Then the reference plane 5 is a horizontal plane that passes through the center. At this time, the reference plane 5 also passes through the limit section 31.

[0057] In some exemplary embodiments, the limiting portion 31 is a planar structure parallel to the side vent 151, such as... Figure 14 and Figure 16 As shown. The center of the limit section 31 is the center of the planar structure.

[0058] For example: for a vertically aligned, straight-line heat exchanger 3, such as Figure 14 As shown, its foremost point is usually the front face of the heat exchanger 3, therefore the limiting part 31 is a planar structure parallel to the reference plane 4, and this front face is usually a rectangular vertical plane. For U-shaped heat exchangers 3 or some multi-fold heat exchangers 3, its foremost point is also the front face of the heat exchanger 3 (e.g. Figure 16 As shown), the limit section 31 is a planar structure parallel to the reference plane 4, and the front end face is usually a rectangular vertical surface.

[0059] When the limiting part 31 is a planar structure, the center of the limiting part 31 is the center of the planar structure, that is, it is located in the middle in both the length and width directions. For the vertical surface of a rectangle, its center is the intersection of the two diagonals.

[0060] In some exemplary embodiments, the air conditioner has a first air outlet mode, a second air outlet mode, and a third air outlet mode.

[0061] Based on the air conditioner being in the first air outlet mode (such as...) Figure 2 , Figure 6 and Figure 10 As shown), the first air guide plate 21 opens the side air vent 151 and the second air guide plate 22 closes the downwind vent 152; Based on the air conditioner being in the second air outlet mode (such as...) Figure 3 , Figure 7 and Figure 11 As shown), the first air guide plate 21 closes the side air vent 151 and the second air guide plate 22 opens the downwind vent 152; Based on the air conditioner being in the third air outlet mode (such as...) Figure 4 , Figure 8 and Figure 12 As shown), the first air guide plate 21 opens the side air vent 151 and the second air guide plate 22 opens the downwind vent 152.

[0062] Three different air outlet modes allow users to choose the appropriate mode according to their needs. The second air outlet mode solves the problem of hot air not reaching the ground in heating mode; the first air outlet mode solves the problem of cold air blowing directly on people in cooling mode; and the third air outlet mode addresses the issues of large airflow blind spots and large temperature differences between near and far areas, effectively solving the pain points of existing duct-type indoor units. Furthermore, this air conditioner can be paired with a standard engineering grille for better coordination with home décor, making it popular with users; or it can be equipped with an electric control panel to further enhance the user experience.

[0063] In some exemplary embodiments, such as Figure 4 As shown, the side air vent 151 and the downwind vent 152 are located inside the housing 1. The housing 1 is also provided with a front air outlet that is connected to the side air vent 151 and a downwind vent that is connected to the downwind vent 152.

[0064] A first air passage is formed between the side air vent 151 and the first air outlet 161, and a second air passage is formed between the downwind vent 152 and the second air outlet 162. This allows for the reasonable setting of the positions of the side air vent 151 and the downwind vent 152, as well as the shapes of the first air guide plate 21 and the second air guide plate 22, as needed. This helps to optimize the structural layout of the air conditioner without affecting its appearance.

[0065] An air outlet flange 163 may be protruded at the first air outlet 161, such as Figure 13 As shown. Ventilation components such as canvas hoses can be fitted onto the air outlet flange 163, so that the air output from the first air outlet 161 can be transported to the air outlet opening on the ceiling through the ventilation components.

[0066] Similarly, an air outlet flange 163 can also be provided at the second air outlet 162 so that the air output from the second air outlet 162 can be transported to the air outlet opening on the ceiling through the ventilation components.

[0067] In some exemplary embodiments, the housing 1 is provided with an air inlet 111 communicating with the air duct 14, such as... Figure 13 As shown. The air inlet 111 is located at the bottom and / or side of the housing 1. In other words, the air conditioner can have side air intake or bottom air intake, which is convenient to choose according to the installation scenario and helps to expand the range of application scenarios.

[0068] In some exemplary embodiments, such as Figure 13 As shown, the housing 1 includes a casing, which includes an outer shell 11, a water collection tray 12 connected to the outer shell 11, and an air guide support 13 connected to the outer shell 11 and the water collection tray 12. The air guide support 13 has a side air outlet 151, and the water collection tray 12 and the air guide support 13 together form a downwind outlet 152. At least the first air guide plate 21 is rotatably connected to the air guide support 13.

[0069] The water receiving tray 12 can be located inside the outer casing 11 and below the indoor heat exchanger 3, and can be connected to the bottom of the outer casing 11. The air guide support 13 can be located inside the outer casing 11 and connected to the front of the outer casing 11 and the top of the water receiving tray 12.
