[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0039] In the related art, the edge of the heat exchanger is located at the edge of the volute at the entrance of the air duct and will not extend into the space between the volute and the casing. The casing part opposite to the volute will not be provided with an air inlet structure, which limits the air inlet area of ​​the air conditioner and affects the air volume of the air conditioner. In addition, since the setting position of the heat exchanger is relatively limited, the heat exchange area of ​​the heat exchanger is small, which affects the heat exchange capacity of the heat exchanger, thereby causing the working performance of the air conditioner to be very limited.

[0040] The utility model provides an air conditioner.

[0041] See also Figure 1 and Figure 2 In one embodiment of the utility model, the air conditioner comprises:

[0042] A housing 100, wherein the housing 100 is formed with an air outlet 111 and an air inlet communicating with an indoor environment, wherein the air inlet includes a first air inlet area 121 and a second air inlet area 122 which are arranged opposite to each other in a width direction of the air outlet 111;

[0043] The heat exchanger 200 is disposed in the housing 100, and includes a first heat exchange portion 210 and a second heat exchange portion 220, wherein the first heat exchange portion 210 is disposed opposite to the first air inlet area 121, and the second heat exchange portion 220 is disposed opposite to the second air inlet area 122;

[0044] The volute 300 and the volute tongue 400, an air duct 500 is formed between the volute 300 and the volute tongue 400, and both ends of the air duct 500 are respectively connected to the air inlet and the air outlet 111, and the volute 300 is arranged opposite to and spaced from the first heat exchange part 210 on the air outlet side of the first heat exchange part 210.

[0045] In the technical solution of the present utility model, in addition to setting the second air inlet area 122 at the position opposite to the volute tongue 400 on the housing 100, the first air inlet area 121 is also set at the position opposite to the volute 300, thereby increasing the air inlet area of ​​the air conditioner, which is beneficial to increasing the air volume of the air conditioner. Furthermore, the first heat exchange part 210 extends between the first air inlet area 121 and the volute 300, and the air entering from the first air inlet area 121 can exchange heat with the first heat exchange part 210. In addition, the air entering from the second air inlet area 122 can exchange heat with the second heat exchange part 220, thereby increasing the heat exchange area of ​​the heat exchanger 200, thereby improving the heat exchange capacity of the heat exchanger 200. The present utility model improves the working performance of the air conditioner by increasing the air volume of the air conditioner and the heat exchange capacity of the heat exchanger 200.

[0046] Among them, the air outlet side of the first heat exchange part 210 and the volute 300 are arranged at intervals, and the air after heat exchange with the first heat exchange part 210 can flow smoothly through the interval to the entrance of the air duct 500. Further, there is also a gap between the air inlet side of the first heat exchange part 210 and the casing 100 of the first air inlet area 121 to provide enough space for the air to fully exchange heat with the first heat exchange part 210. Specifically, the minimum spacing between the first heat exchange part 210 and the volute 300 is preferably 8 mm to 30 mm, and the minimum spacing between the first heat exchange part 210 and the casing 100 at the first air inlet area 121 is 10 mm to 20 mm. Of course, in other embodiments, the above two spacings can also be other values, as long as the performance requirements of the air conditioner can be met.

[0047] See also Figure 5 In the present invention, the air entering the casing from the first air inlet area 111 and the second air inlet area 112 can have a sufficient flow rate, that is, the first air inlet area 111 and the second air inlet area 112 can allow a large amount of air to enter to ensure the air volume of the air conditioner.

[0048] Furthermore, in this embodiment, if Figure 6As shown, the air conditioner also includes a crossflow fan wheel 600, a line connecting the end of the volute 300 and the rotation axis of the crossflow fan wheel 600 is a first imaginary line L1, a line connecting the end of the volute tongue 400 and the rotation axis of the crossflow fan wheel 600 is a second imaginary line L2, an angle between the first imaginary line L1 and the second imaginary line L2 is α, a line connecting the end of the first heat exchange portion 210 and the rotation axis of the crossflow fan wheel 600 is a third imaginary line L3, a line connecting the end of the second heat exchange portion 220 and the rotation axis of the crossflow fan wheel 600 is a fourth imaginary line L4, an angle between the third imaginary line and the fourth imaginary line is β, ∠β is greater than ∠α. In this way, the coverage of the entrance of the air duct 500 by the heat exchanger 200 can be guaranteed. The first heat exchange part 210 will be located on the flow path from the first air inlet area 121 through the side where the volute 300 is located to the inside of the air duct 500, and the second heat exchange part 220 will be located on the flow path from the second air inlet area 122 through the side where the volute tongue 400 is located to the inside of the air duct, which is beneficial to ensure sufficient heat exchange between the air and the heat exchanger 200.

[0049] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the first heat exchange portion 210 at least partially surrounds the outer side of the volute 300 away from the crossflow impeller 600. This is beneficial to extend the flow path from the first air inlet area 121 to the entrance of the air duct 500 to ensure sufficient heat exchange between the air and the heat exchanger 200.

[0050] Further, in this embodiment, the heat exchanger 200 is an integrated structure, and the heat exchanger 200 is an integrated structure, and the two side edges of the heat exchanger 200 opposite to each other in the extension direction are the side edges of the first heat exchange part and the second heat exchange part. Specifically, the heat exchanger 200 has a first side edge and a second side edge opposite to each other in the extension direction, the first side edge is the edge of the first heat exchange part 210 close to the air outlet 111, and the second side edge is the edge of the second heat exchange part 220 close to the air outlet 111. That is, the first heat exchange part 210 and the second heat exchange part 220 are respectively the structures of the two sides of the heat exchanger 200 in the extension direction, and the two edges of the heat exchanger 200 are respectively the edges of the first heat exchange part 210 and the second heat exchange part 220. The heat exchanger 200 is set as an integrated structure as a whole, which can facilitate the processing and installation of the heat exchanger 200, and at the same time, it is conducive to ensuring the structural stability of the heat exchanger 200. Of course, in other embodiments, the heat exchanger 200 may also be configured as a segmented structure, with the first heat exchange portion 210 and the second heat exchange portion 220 being two separate segments of the heat exchanger 200 and being spliced ​​together after processing.

[0051] Furthermore, in this embodiment, the cross section of the heat exchanger 200 is a "U" shape with an opening toward the air outlet 111. Specifically, with respect to the cross section of the heat exchanger 200, the first heat exchange portion 210 and the second heat exchange portion 220 are substantially straight sections, and the middle section connecting the first heat exchange portion 210 and the second heat exchange portion 220 can be as follows: Figure 2 As shown, the whole is arc-shaped, or it can be Figure 1 As shown, it includes a straight section opposite to the back side of the housing 100, and the two ends of the straight section are connected to the first heat exchange part 210 and the second heat exchange part 220 through an arc section, or the cross section of the heat exchanger 200 can also be other "U"-shaped structures. In this way, the space in the housing 100 can be fully utilized, which is conducive to the miniaturization design of the air conditioner. At the same time, it can ensure that the heat exchanger 200 has a sufficient heat exchange area, thereby ensuring the heat exchange capacity of the heat exchanger 200. Of course, in other embodiments, the cross section of the heat exchanger 200 can also be "V"-shaped.

[0052] Further, in this embodiment, the side edge of the first heat exchange portion is arranged corresponding to the edge of the first air inlet area 121, and the side edge of the second heat exchange portion is arranged corresponding to the edge of the second air inlet area 122. It can be understood that the first heat exchange portion 210 and the second heat exchange portion 220 are exposed in the corresponding air inlet area, and can well exchange heat with the air. Specifically, the first side edge is arranged corresponding to the edge of the first air inlet area 121 close to the air outlet 111, and the second side edge is arranged corresponding to the edge of the second air inlet area 122 close to the air outlet 111. In the length direction of the air outlet 111, the side edge of the heat exchanger 200 is also arranged corresponding to the side edge of the air inlet area. In this way, in this embodiment, the edge of the first heat exchange part 210 and the edge of the second heat exchange part 220 are respectively arranged flush or substantially flush with the side edge of the corresponding air inlet area, and will not extend too far into the closed structure of the housing 100. While fully utilizing the air inlet area of ​​the air inlet area, the heat exchange area of ​​the heat exchanger 200 can also be fully utilized, thereby ensuring the ability of the heat exchanger 200 to exchange heat with the air, so as to ensure the working performance of the air conditioner. In particular, when the air outlet 111 is arranged at the front side of the housing 110, the first side edge and the second side edge are also the two front edges of the heat exchanger 200. Of course, in other embodiments, considering the installation convenience or installation stability of the heat exchanger 200 , the heat exchanger 200 may be appropriately extended to the position where the closed structure of the casing 100 is located.

[0053] Furthermore, in this embodiment, if Figure 1 and Figure 2As shown, the air duct 500 includes an air inlet section 510, and the crossflow impeller 600 is arranged corresponding to the entrance of the air inlet section 510. The crossflow impeller 600 has low operating noise and strong air supply capacity. In this way, while ensuring the noise performance of the air conditioner, the air volume of the air conditioner can also be guaranteed, which is conducive to ensuring the user experience. Of course, in other embodiments, the air conditioner can also use an axial flow impeller or a centrifugal impeller.

[0054] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, in the direction away from the air outlet 111, the air inlet section 510 is arranged obliquely toward the second heat exchange part 220. In this way, after the air from the first air inlet area 121 enters the housing 100 and exchanges heat with the first heat exchange part 210, it will flow to the air inlet side of the crossflow impeller 600 under the guidance of the outer wall surface of the volute 300, and after the air from the second air inlet area 122 enters the housing 100 and exchanges heat with the second heat exchange part 220, it will also reach the air inlet side of the crossflow impeller 600. Under the disturbance of the crossflow impeller 600, the air on the air inlet side of the crossflow impeller 600 will flow into the air duct 500 through the air inlet section 510.

[0055] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the crossflow impeller 600 is centrally arranged between the first air inlet area 121 and the second air inlet area 122. In this way, the deflection angle of the air duct 500 is smaller, and the pressure loss of the air in the air duct 500 is small, which is conducive to ensuring the flow rate of the air, thereby ensuring the air outlet performance of the air conditioner.

[0056] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the air duct 500 includes an air outlet section 530 and an air guide section 520 adjacent to the air outlet section 530, the air outlet 111 is located on the side of the air outlet section 530 away from the air guide section 520, and is located on the front side of the housing 100; in the direction toward the air outlet 111, the air guide section 520 extends obliquely toward the side where the second air inlet area 122 is located, and the air outlet section 530 deflects relative to the air guide section 520 in the direction away from the side where the second air inlet area 122 is located. The oblique extension of the air guide section 520 is conducive to guiding the air on the air outlet side of the crossflow impeller 600, and the deflection of the air outlet section 530 is conducive to correcting the air flow direction, so that the air can be more biased to the front, so as to give the user a better blowing feeling. It should be noted that the deflection angle of the air outlet section 530 should not be too large, and the angle between the extension direction of the air outlet section 530 and the front should be within 10 degrees.

[0057] Furthermore, in this embodiment, if Figure 1 and Figure 2As shown, the volute 300 includes a first guide section 310 and a second guide section 320 corresponding to the air outlet section 530. In the direction close to the air outlet 111, the first guide section 310 and the second guide section 320 are connected in sequence, and the first guide section 310 is inclined toward the side where the first air inlet area 121 is located, and the second guide section 320 extends forward. It can be understood that the volute 300 is inclined toward the second air inlet area 122 in the air guide section 520. The first guide section 310 is directed toward the first air inlet area 121, and the volute 300 relative to the air guide section 520 is deflected relatively greatly in the direction away from the volute tongue 400, which is equivalent to expanding the width of the air duct 500. In addition, the second guide section 320 extends forward relatively straight, which can make the position of the air outlet 111 more centered, and at the same time, it can expand the area of ​​the air outlet 111, thereby ensuring the air outlet performance of the air conditioner. Among them, the second guide section 320 extends forward, which is specifically manifested as the angle between the second guide section 320 and the front is within 10 degrees. For the third guide section 410 corresponding to the air outlet section 530 on the volute 400, it also extends forward, that is, the angle between the third guide section 410 and the front is also within 10 degrees, and the angle between the second guide section 320 and the third guide section 410 is within 10 degrees, thereby ensuring that the air conditioner is more inclined to the front. Furthermore, an air guide plate is also provided at the position of the air outlet section 530. The air guide plate can include a horizontal air guide plate and a vertical air guide plate. The horizontal air guide plate can swing vertically, and the vertical air guide plate can swing horizontally. The air outlet direction of the air conditioner is adjusted by the horizontal air guide plate and the vertical air guide plate, or the air swing of the air conditioner is realized.

[0058] Furthermore, in this embodiment, if Figures 1 to 4 As shown, the housing 100 includes two side panels 120 arranged opposite to each other in the width direction of the air outlet 111, and the first air inlet area 121 and the second air inlet area 122 are respectively formed on the two side panels 120. Specifically, the two side panels 120 form the first air inlet area 121 and the second air inlet area 122 respectively by setting a grille structure. It can be understood that the housing 100 also includes a front panel 110 and a back panel 130, the front panel 110 is formed with an air outlet 111, and the two sides are respectively connected to one edge of the two side panels 120, and the back panel 130 is connected to the side of the two side panels 120 away from the air outlet 111, so that the installation space inside the housing 100 is enclosed by the front panel 110, the back panel 130 and the two side panels 120, and the cross-sectional profile of the housing 100 is square or approximately square. Of course, in other embodiments, the cross-sectional profile of the air conditioner can also be circular or quasi-circular.

[0059] Furthermore, in this embodiment, if Figure 4As shown, the back plate 130 is provided with a hanging structure 131. In this embodiment, the back plate 130 can be mounted on the external structure through the hanging structure 131, so that the air conditioner can be installed off the ground, so that the position of the air outlet 111 is opposite to the main part of the human body trunk, giving the user a better blowing feeling. Specifically, the hanging structure 131 on the back plate 130 can be, but is not limited to, a certain position of the upper area of ​​the back plate 130 is recessed to form a hanging groove, or a hook-shaped part or a U-shaped accessory with an opening facing downward is installed on the back plate 130. Of course, in other embodiments, the air conditioner can also be installed on the ground.

[0060] Specifically, the air conditioner can be a vertical cabinet or a wall-mounted cabinet. The vertical cabinet is also a floor-standing installation, which is convenient to install, while the wall-mounted cabinet is installed on the wall off the ground, so that the position of the air outlet 111 is opposite to the main part of the human body trunk, giving the user a better blowing feeling. Of course, in other embodiments, the air conditioner can also be configured as a split air conditioner, including the above-mentioned vertical cabinet or wall-mounted cabinet and an outdoor unit, or the air conditioner can also be other forms of air conditioning equipment, such as an integrated air conditioner.

[0061] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
