Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] There are many types of air conditioner indoor units. In order to better meet specific usage requirements, some air conditioner indoor units have air inlets set on the front surface of their shells instead of on the upper surface, so that the air conditioner indoor unit can take in air from the front. For example, for an embedded air conditioner indoor unit installed in a cabinet, since its upper side may be close to the top wall of the cabinet, the top air intake effect is poor, so the air inlet can be set on the front surface to take in air from the cabinet opening.

[0003] However, if the air inlet of the air conditioner indoor unit is set at the front side, even if the user does not use the air conditioner indoor unit, the air inlet is still exposed to the environment, which not only affects the aesthetics of the air conditioner indoor unit, but also easily causes dust to fall into the air inlet.

[0053] Figure 1 Schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the present utility model.

[0054] refer to Figure 1 As shown, this embodiment provides an air conditioner indoor unit 20 , and the air conditioner indoor unit 20 includes: a housing 21 , an air inlet baffle 22 and a supporting device 23 .

[0055] An air inlet is provided on the front surface of the housing 21. An air inlet baffle 22 is provided on the front side of the housing 21 and is used to open and close the air inlet. A supporting device 23 is provided on the housing 21 and is used to support the air inlet baffle 22 and guide the air inlet baffle 22 to move forward and backward, thereby opening and closing the air inlet.

[0056] The air inlet of the indoor unit 20 of the air conditioner of the present invention is provided on the front surface of the housing 21, and the front side of the housing 21 is provided with an air inlet baffle 22 for opening and closing the air inlet, and a supporting device 23 is provided on the housing 21 for supporting the air inlet baffle 22 and guiding the air inlet baffle 22 to move forward and backward, thereby opening and closing the air inlet. The utility model enables the indoor unit 20 of the air conditioner to close the air inlet by providing the air inlet baffle 22 that can open and close the air inlet, so that the air inlet is not exposed to the user's sight.

[0057] When the air inlet is opened, an air inlet gap will be formed between the surrounding side of the air inlet baffle 22 and the front surface of the shell 21 of the air conditioner indoor unit 20, so that air can enter the air conditioner indoor unit 20 through the upper, lower, left and right edges of the air inlet baffle 22 through the air inlet gap.

[0058] exist Figure 1 In the illustrated embodiment, the air conditioner indoor unit 20 includes two sets of support devices 23, which are arranged on both lateral sides of the air conditioner indoor unit 20 to simultaneously provide support for both lateral sides of the air inlet baffle 22. It can be understood that Figure 1 In the embodiment, the support device 23 on one side is not visible because it is blocked by the air inlet baffle 22 .

[0059] In some optional embodiments, the air conditioner indoor unit 20 may also include only one set of supporting devices 23, which are arranged in the transverse middle of the air conditioner indoor unit 20 and connected to the transverse middle of the air inlet baffle 22. Of course, the air conditioner indoor unit 20 may also include three or more sets of supporting devices 23, which is not limited here.

[0060] The support device 23 guides the air inlet baffle 22 to move forward and backward, which means that the support device 23 guides the air inlet baffle 22 to maintain vertical movement forward and backward, which may be a translation toward the front or rear, or an oblique upward or downward movement, but does not include guiding the air inlet baffle 22 to rotate, that is, causing the inlet baffle 22 to change its tilt angle.

[0061] The supporting device 23 of this embodiment may be a transmission connecting rod composed of one or more connecting rods, or may be a mechanical arm or a mechanical rod capable of moving forward and backward, such as an electric push rod or an electric lead screw.

[0062] The supporting device 23 is arranged on the shell 21, which means that the supporting device 23 can be arranged on the outside of the shell 21, such as on the outer surface of one lateral side or two side walls of the shell 21, or can be arranged on the inside of the shell 21, such as directly on the inner surface of one lateral side or two side walls of the shell 21, or indirectly connected and fixed to the shell 21 through other connecting structures.

[0063] Figure 22 is a schematic perspective view of an indoor unit 20 of an air conditioner according to an embodiment of the present utility model, in order to more clearly and intuitively illustrate the structure of the supporting device 23, Figure 2 The other devices, components and structures except the housing 21, the air inlet baffle 22 and the supporting device 23 of the air conditioner indoor unit 20 are hidden, and the positions of the air inlet baffle 22 and the supporting device 23 when the air inlet is closed are indicated by dotted lines.

[0064] refer to Figure 2 As shown, the supporting device 23 includes: a first supporting link 231, and a second supporting link 232 which is arranged to cross the first supporting link 231 and is rotatably connected at the crossing position.

[0065] The first supporting link 231 has a first end rotatably connected to the housing 21, and the second supporting link 232 has a first end slidably connected to the housing 21. One of the first supporting link 231 and the second supporting link 232 has a second end rotatably connected to the air inlet baffle 22, and the other has a second end slidably connected to the air inlet baffle 22.

[0066] refer to Figure 2 As shown, the air inlet baffle 22 of this embodiment is arranged vertically, and the supporting device 23 includes a first supporting link 231 and a second supporting link 232 which are arranged crosswise and rotatably connected at the cross position, the first ends of the first supporting link 231 and the second supporting link 232 are longitudinally aligned and the second ends are also longitudinally aligned (that is, the projections on the horizontal plane are located at the same position), and the cross position is located at the center of the respective lengths of the first supporting link 231 and the second supporting link 232. Therefore, when the angle between the first supporting link 231 and the second supporting link 232 changes, and the first ends of the first supporting link 231 and the second supporting link 232 are close to or away from each other, the first end of the first supporting link 231 and the second end of the second supporting link 232 will be correspondingly away from or close to each other.

[0067] In some embodiments where the air inlet baffle 22 is tilted or the surface of the air inlet baffle 22 is not a vertical plane, the first end or the second end of the first support link 231 and the second support link 232 may not be longitudinally aligned, and the intersection position may not be located at the center of the respective lengths of the first support link 231 and the second support link 232. As long as the first end of the first support link 231 is fixed and the first end of the second support link 232 moves vertically up and down, the support device 23 can guide the air inlet baffle 22 to move forward and backward to open and close the air inlet.

[0068] In some optional implementations, the air conditioner indoor unit 20 further includes a driving device (not shown in the figure). The driving device is used to drive the first end of the second supporting link 232 to move up and down.

[0069] Since the first end of the first supporting link 231 is fixed, by setting a driving device to drive the first end of the second supporting link 232 to move up and down, the second end of the second supporting link 232 can be translated forward and backward, and at the same time, the second end of the first supporting link 231 moves up and down synchronously with the first end of the second supporting link 232 and moves forward and backward synchronously with the second end of the second supporting link 232. With the movement of the second ends of the first supporting link 231 and the second supporting link 232, the air inlet baffle 22 connected to the second ends of the first supporting link 231 and the second supporting link 232 also moves forward and backward accordingly, thereby opening or closing the air inlet.

[0070] The driving device may be any electric driving device including an electric hydraulic push rod and an electric ball screw. The driving device is connected to the first end of the second supporting link 232 and drives the first end of the second supporting link 232 to move upward or downward.

[0071] exist Figure 2 In the illustrated embodiment, the first end of the first support link 231 is located above the first end of the second support link 232, so the driving device can be arranged below the first end of the second support link 232, so as to push the first end of the second support link 232 upward to push the air inlet baffle 22 forward to open the air inlet, or pull the first end of the second support link 232 downward to pull the air inlet baffle 22 backward to close the air inlet. The driving device can also be arranged above the first end of the second support link 232. Below and above here include directly above and obliquely above.

[0072] In other embodiments, the first end of the first support link 231 may also be located below the first end of the second support link 232, but the principles of opening and closing the air inlet are similar and will not be described in detail.

[0073] It should be noted that, in this embodiment, the air inlet can be opened and closed both automatically and manually, that is, in some embodiments where the air conditioner indoor unit 20 is not provided with a driving device, the user can also manually push and pull the air inlet baffle 22, and the air inlet baffle 22 can be opened and closed in a specific direction and maintain an open or closed state under the support and guidance of the supporting device 23.

[0074] In some optional embodiments, the supporting device 23 further includes: a first sliding groove 233 and a second sliding groove 234 .

[0075] The first sliding groove 233 is fixed on the housing 21 in the longitudinal direction; a sliding block 232A is disposed in the first sliding groove 233, and the sliding block 232A in the first sliding groove 233 is rotatably connected to the first end of the second supporting link 232, thereby limiting the first end of the second supporting link 232 from sliding along the first sliding groove 233; and

[0076] The second sliding groove 234 is fixed on the air inlet baffle 22 in the longitudinal direction; at least one sliding block 231B and / or 232B is arranged in the second sliding groove 234, and the sliding block 231B and / or 232B in the second sliding groove 234 is rotatably connected to the second end of the first support link 231 and / or the second support link 232, thereby limiting the second end of the first support link 231 and / or the second support link 232 from sliding along the second sliding groove 234.

[0077] Figure 3 2 is a schematic perspective view of an air conditioner indoor unit 20 according to another embodiment of the present invention, in order to more clearly and intuitively illustrate the structure of the supporting device 23, Figure 3 The other devices, components and structures except the housing 21, the air inlet baffle 22 and the supporting device 23 of the air conditioner indoor unit 20 are hidden, and the positions of the air inlet baffle 22 and the supporting device 23 when the air inlet is closed are indicated by dotted lines.

[0078] Figure 2 and Figure 3 The figures show an embodiment of a supporting device 23 and an embodiment of an air inlet baffle 22. Figure 2 In the illustrated embodiment, the first end of the first support link 231 is rotatably connected to the housing 21, and the second end of the second support link 232 is rotatably connected to the air inlet baffle 22. The sliding block 232A in the first sliding groove 233 is rotatably connected to the first end of the second support link 232, thereby limiting the first end of the second support link 232 from sliding up and down along the first sliding groove 233. The sliding block 231B in the second sliding groove 234 is rotatably connected to the second end of the first support link 231, thereby limiting the second end of the first support link 231 from sliding up and down along the second sliding groove 234.

[0079] Although Figure 2 In the embodiment, a sliding block 231A connected to the first supporting link 231 is further provided in the first sliding groove 233, and a sliding block 232B connected to the second supporting link 232 is further provided in the second sliding groove 234. However, in the embodiment, the first end of the first supporting link 231 can be Figure 2 In the embodiment shown, the sliding block 231A fixed in the first sliding groove 233 is rotatably connected to the housing 21 indirectly, or the sliding block 231A may not be provided and the housing 21 may be directly connected. Figure 2 In the embodiment shown, the sliding block 232B fixed in the second sliding groove 234 is rotatably connected to the air inlet baffle 22 indirectly, or the sliding block 232B may not be provided and the air inlet baffle 22 may be directly connected.

[0080] exist Figure 2 In the embodiment shown, since the relative position of the first end of the first supporting link 231 and the housing 21 is fixed, and the relative position of the second end of the second supporting link 232 and the air inlet baffle 22 is fixed, the air inlet baffle 22 will be as follows during the opening and closing process. Figure 2 The dotted line to solid line position schematically maintains forward and backward translation without shifting up and down.

[0081] The driving device in this embodiment can be directly connected to the first end of the second supporting link 232 , or can be connected to the sliding block 232A and thus indirectly connected to the first end of the second supporting link 232 .

[0082] The air inlet baffle 22 in this embodiment can move parallely in the front-to-back direction, and thus can be well applied to an environment where there is insufficient space above the air conditioner indoor unit 20. When opened, the air inlet baffle 22 will not collide with the cabinets, walls or other objects above the air conditioner indoor unit 20.

[0083] exist Figure 3 In the illustrated embodiment, the first end and the second end of the first support link 231 are rotatably connected to the housing 21 and the air inlet baffle 22, respectively. The sliding block 232A in the first sliding groove 233 is rotatably connected to the first end of the second support link 232, thereby limiting the first end of the second support link 232 from sliding up and down along the first sliding groove 233. The sliding block 232B in the second sliding groove 234 is rotatably connected to the second end of the second support link 232, thereby limiting the second end of the second support link 232 from sliding up and down along the second sliding groove 234.

[0084] and Figure 2 Similar to the embodiment shown in FIG. 1 , the first supporting link 231 in this embodiment can be Figure 3 As shown in the embodiment, the sliding block 231A is rotatably connected to the shell 21 indirectly through being fixed in the first sliding groove 233, and is rotatably connected to the air inlet baffle 22 indirectly through being fixed in the second sliding groove 234, but the sliding block 231A and the sliding block 231B may be omitted and the shell 21 and the air inlet baffle 22 may be directly connected.

[0085] exist Figure 3 In the embodiment shown, since the relative position of the first end of the first supporting link 231 and the housing 21 is fixed, and the relative position of the second end of the first supporting link 231 and the air inlet baffle 22 is fixed, when the air inlet baffle 22 is opened, the second end of the first supporting link 231 moves upward while moving forward, so the supporting device 23 drives the air inlet baffle 22 to move upward. Figure 3 The dotted line to the solid line position schematically moves diagonally upward.

[0086] In this embodiment, when the air inlet is opened, since the air inlet baffle 22 is located obliquely above the air inlet, a part of the air inlet can inhale air from the front without bypassing the air inlet baffle 22. Figure 2 The illustrated embodiment has a relatively better air intake effect and is suitable for an environment where there is sufficient space above the indoor unit 20 of the air conditioner to support the movement of the air inlet baffle 22 diagonally upward.

[0087] In some optional embodiments, the number of sliding blocks in the second sliding groove 234 is two, and the sliding blocks 231B and 232B in the two second sliding grooves 234 are rotatably connected to the second ends of the first supporting link 231 and the second supporting link 232 respectively.

[0088] The supporting device 23 further includes a locking member 235. The locking member 235 is detachably disposed on the second sliding groove 234, and is used to fix the sliding block 231B or 232B connected to the second end of the first supporting link 231 or the second supporting link 232 to the second sliding groove 234, so that the second end of the first supporting link 231 or the second supporting link 232 is rotatably connected to the air inlet baffle 22.

[0089] refer to Figure 2 and Figure 3 As shown, in this embodiment, a locking member 235 is provided to prevent one of the two sliding blocks 231B or 232B in the second sliding groove 234 from moving in the second sliding groove 234, thereby switching the air inlet baffle 22 as shown in FIG. Figure 2 As shown, move forward and backward or as shown Figure 3 When the user installs the air conditioner indoor unit, the user can conveniently switch the indoor unit 20 according to the installation environment space and use requirements.

[0090] The locking member 235 can be a pluggable member. The second sliding groove 234 has through holes at the corresponding positions of the two sliding blocks 231B and 232B when the air inlet baffle 22 is closed. When the locking member 235 is inserted into a through hole, the sliding block 231B or 232B at the corresponding position is prevented from moving upward, so that the weight of the air inlet baffle 22 is borne on the corresponding sliding block 231B or 232B. The locking member 235 can also be a screw, a buckle, or other locking members 235 that can be used to prevent the sliding block 231B or 232B in the second sliding groove 234 from moving upward or moving in any direction.

[0091] Figure 4 is a schematic cross-sectional view of an air conditioner indoor unit 20 according to an embodiment of the utility model;

[0092] refer to Figure 4As shown, in some optional embodiments, an air inlet is opened at the upper portion of the front surface of the shell 21 , and an air outlet is opened at the lower portion of the front surface of the shell 21 .

[0093] The air conditioner indoor unit 20 of this embodiment can be an embedded air conditioner indoor unit 20, that is, the air conditioner indoor unit 20 is embedded in the cabinet. Different from the traditional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded in the cabinet, so that the air conditioner indoor unit 20 is hidden in appearance, making the home layout more beautiful.

[0094] In order to adapt to the opening of the cabinet, the air conditioner indoor unit 20 of this embodiment is provided with an air inlet on the upper part of the front surface of the shell 21, and the air outlet is provided on the lower part of the front surface of the shell 21. That is to say, the front surface of the shell 21 is provided with an air inlet and an air outlet at the same time, that is, the air inlet and outlet of the air conditioner indoor unit 20 are located on the same side and correspond to the opening position of the cabinet, so that the air conditioner indoor unit 20 can take in and out air from the front at the same time.

[0095] In some optional implementations, the air conditioner indoor unit 20 further includes: an air supply fan 24 , a heat exchanger 25 , and an air inlet baffle 26 .

[0096] The air supply fan 24 is arranged in the housing 21, and is used to promote the formation of an air flow that enters the air conditioner indoor unit 20 from the air inlet and blows out from the air outlet. The heat exchanger 25 is arranged in the housing 21, and is located between the air inlet and the air supply fan 24, and is used to exchange heat with the air flow that enters the air conditioner indoor unit 20 from the air inlet. The air inlet baffle 26 is horizontally arranged in the housing 21, and one end is close to the air inlet, and the other end is close to the heat exchanger 25, so as to separate the air flow that enters the air conditioner indoor unit 20 from the air inlet into two parts, an upper part and an lower part.

[0097] The air inlet baffle 26 is horizontally arranged in the housing 21, with one end close to the air inlet and the other end close to the heat exchanger 25, so as to separate the air flow entering the air conditioner indoor unit 20 from the air inlet into two upper and lower parts.

[0098] refer to Figure 4 As shown, in order to improve the heat exchange efficiency, the air conditioner indoor unit 20 of this embodiment has a heat exchanger 25 arranged on the upper peripheral side of the air supply fan 24, wherein part of the heat exchanger 25 is close to and faces the air inlet of the air conditioner indoor unit 20, while another part of the heat exchanger 25 is away from the air outlet due to being bent backward and downward.

[0099] Figure 4The arrows indicate the direction of air flow at the air inlet. In order to prevent the air flow from only passing through the front half of the heat exchanger 25 close to the air inlet, causing the rear half of the heat exchanger 25 to not participate in or participate less in heat exchange, an air inlet baffle 26 is particularly provided in the shell 21. One end of the air inlet baffle 26 is close to the air inlet, and the other end is close to the heat exchanger 25, thereby dividing the airflow entering the air conditioner indoor unit 20 from the air inlet into two parts, an upper part and a lower part.

[0100] The air conditioner indoor unit 20 of this embodiment utilizes the spacing of the air inlet baffle 26 to allow the air flow entering the air conditioner indoor unit 20 from the lower air inlet to pass through the front half heat exchanger 25, while also ensuring that the air flow entering the air conditioner indoor unit 20 from the upper air inlet can flow to and pass through the rear half heat exchanger 25, thereby making full use of the heat exchanger 25 and avoiding the accumulation of cold energy.

[0101] In this embodiment, a gap is formed between the upper end of the heat exchanger 25 and the upper part of the shell 21 to allow air flow to pass through, and the end of the air inlet baffle 26 can be close to the upper end of the heat exchanger 25, thereby dividing the heat exchanger 25 into two parts, front and back, and ensuring that the air flow entering from the air inlet of the upper half is guided to the rear half of the heat exchanger 25.

[0102] In some embodiments of the present application, the air inlet baffle 26 may not be horizontally arranged in the housing 21, that is, it may be inclined or bent, and the airflow entering the air conditioner indoor unit 20 from the air inlet is also divided into upper and lower parts. However, the above embodiment may affect the normal flow of the airflow and cause the air intake efficiency of the air conditioner indoor unit 20 to decrease, and therefore it is generally not the most preferred embodiment.

[0103] In some optional embodiments, the heat exchanger 25 may also be Figure 4 The illustrated embodiment is arranged on the upper peripheral side of the air supply fan 24, for example, it can be arranged in the shell 21 longitudinally or in other ways, and the air inlet baffle 26 can also be correspondingly arranged with its end located in the middle of the height of the heat exchanger 25, thereby dividing the heat exchanger 25 into two upper and lower parts opposite to the air inlet.

[0104] In some optional implementations, the air conditioner indoor unit 20 further includes: a first air guide plate 31 .

[0105] The first air guide plate 31 is disposed at the air outlet and has a rotation axis close to the upper side of the air outlet and extending laterally.

[0106] Figure 4The diagram shows a position of the first air guide plate 31 when it is in the open state. The first air guide plate 31 of this embodiment is turned upward around the rotation axis near the upper side of the air outlet, and uses its own plate body to separate the air inlet from the air outlet. Therefore, when the first air guide plate 31 of this embodiment is opened, it can not only guide the outlet air flow by adjusting the rotation height and change the air outlet distance, but also separate the air inlet and the air outlet on its upper and lower sides, so as to prevent the air inlet from directly sucking the heat exchange air flow blown out from the air outlet back into the air conditioner indoor unit 20, thereby optimizing the air inlet and outlet effects of the air conditioner indoor unit 20 and improving the heat exchange efficiency and air supply effect.

[0107] In some optional embodiments, one end of the first air guide plate 31 away from the rotation axis is bent toward the air outlet.

[0108] Figure 4 The arrows indicate the direction of airflow at the air outlet. The first air guide plate 31 of this embodiment is bent toward the air outlet at one end away from the rotation axis, thereby forming a concave arc surface. When the first air guide plate 31 is opened and the air conditioner indoor unit 20 is discharging air, the airflow direction at the air outlet is guided to tilt downward along the arc surface.

[0109] Since the air outlet of the embedded air conditioner indoor unit 20 is located at the front side thereof, the shape of the first air guide plate 31 of the present embodiment can ensure that the airflow can be blown obliquely downward when the opening of the air outlet is large, so as to avoid the situation where the air supply height of the air conditioner indoor unit 20 is too high and cannot meet the direct blowing requirements of some users. In addition, the airflow blown from the air outlet tends to flow away from the air inlet side due to the guidance of the first air guide plate 31, so it also has a certain effect in preventing the airflow blown from the air outlet from being directly sucked into the air inlet again.

[0110] The first air guide plate 31 of this embodiment can be a plate body that is bent and has an overall arc shape, or a plate body that is bent and has an arc shape. Figure 4 Schematically, only the surface of the first air guide plate 31 facing the air outlet is bent, while the other side is a straight surface adapted to the shape of the air outlet.

[0111] In some optional embodiments, the air conditioner indoor unit 20 further includes: an air supply duct 27, a second air guide plate 32 and a third air guide plate group.

[0112] The air supply duct 27 is disposed in the housing 21, and one end of the air supply duct is connected to the air outlet. The second air guide plate 32 is disposed in the air supply duct 27, and has a rotation axis extending laterally near the lower surface of the air supply duct 27, and is used to guide the air outlet direction of the air conditioner indoor unit 20. The third air guide plate group is disposed in the air supply duct 27, and includes a plurality of third air guide plates 33 distributed in the transverse direction; each third air guide plate 33 has a rotation axis extending longitudinally, and is used to guide the air outlet direction of the air conditioner indoor unit 20.

[0113] refer to Figure 4 As shown, the air supply duct 27 of this embodiment is connected to the air outlet at one end and to the air supply fan 24 at the other end, so as to guide the air flow formed by the air supply fan 24 to blow toward the air outlet. The first air guide plate 31 is arranged at the air outlet, and the two ends of its rotating shaft are connected to the two lateral walls of the air supply duct 27. The second air guide plate 32 is arranged close to the lower surface of the air supply duct 27, and the two ends of its rotating shaft can also be connected to the two lateral walls of the air supply duct 27.

[0114] The second air guide plate 32 can swing upward from a position close to the lower surface of the air supply duct 27, so as to adjust the air outlet height of the air conditioner indoor unit 20. When the swing height of the second air guide plate 32 is high, the size of the air outlet can also be reduced, so as to change the distance of the air outlet and the perceived wind speed in accordance with the speed change of the air supply fan 24. For example, when the speed of the air supply fan 24 remains unchanged, when the swing height of the second air guide plate 32 is high and the air outlet is reduced, the actual air outlet speed of the air conditioner indoor unit 20 becomes faster due to the reduction of the air outlet. When the speed of the air supply fan 24 decreases, the actual air outlet speed of the air conditioner indoor unit 20 can be maintained stable by reducing the size of the air outlet by swinging the second air guide plate 32, so as to reduce the air supply volume of the air conditioner indoor unit 20 when the perceived wind speed remains basically unchanged, so as to adjust the ambient temperature.

[0115] Figure 4 Only one third air guide plate 33 in the third air guide plate group can be seen, but it can be understood that multiple third air guide plates 33 of this embodiment are arranged side by side in the air supply duct 27. In some optional embodiments, multiple third air guide plates 33 in the third air guide plate group can be synchronously controlled to rotate and adjust the lateral air outlet direction of the air conditioner indoor unit 20.

[0116] exist Figure 4 In the illustrated embodiment, the third air guide plate group is disposed on the lower surface of the air supply duct 27 , while in other optional implementations, the third air guide plate group may also be disposed on the upper surface of the air supply duct 27 .
