[0070] Background Introduction

[0071] With the change of the global climate environment, air pollution, smog and other weather conditions have worsened; the outdoor air has become no longer fresh and clean, and the particulate matter and pollutants in the air have increased year by year, affecting human health.

[0072] Therefore, the fresh air device has become a standard configuration for most models. Currently, the fresh air device installed in the air conditioner occupies a large space inside the air conditioner, resulting in an increase in the size of the air conditioner.

[0073] Based on this, as Figures 1 - 8 shown, in the first aspect of the embodiment of the present application, a cabinet air conditioner is provided, including:

[0074] A housing 100, with an indoor air inlet 101 provided at the rear of the housing 100, and an indoor upper air outlet 102 and an indoor lower air outlet 103 provided at the top and bottom respectively;

[0075] An indoor heat exchanger 500, which is arranged inside the housing 100, and the air flow entering the housing 100 from the indoor air inlet 101 can be discharged from the indoor upper air outlet 102 and / or the indoor lower air outlet 103 after heat exchange through the indoor heat exchanger 500;

[0076] The fresh air component 200 is disposed inside the cabinet 100 and below the indoor heat exchanger 500. The fresh air component 200 includes a first centrifugal fan 201. The rotating shaft of the first centrifugal fan is arranged along the height direction of the cabinet. The first centrifugal fan is formed with an air inlet and an air outlet.

[0077] Wherein, a fresh air inlet 104 communicating with the air inlet of the first centrifugal fan and a fresh air outlet 105 communicating with the air outlet of the first centrifugal fan are formed on the rear surface of the cabinet 100.

[0078] The cabinet air conditioner in the embodiment of the present application includes a fresh air component 200. The fresh air component 200 includes a first centrifugal fan 201 whose rotating shaft is arranged along the height direction of the cabinet. Preferably, the fan is arranged in a flat shape along the height direction of the cabinet 100. This design reduces the vertical space occupied by the fresh air component 200 inside the air conditioner, making the air conditioner more compact, saving the space occupied by the fresh air component 200 in the height direction of the cabinet 100. Thus, the space released in the height direction of the cabinet 100 can be designed as an indoor air inlet 101 for indoor air to enter, so that the air inlet area of the indoor air inlet 101 is larger, thereby realizing the fresh air intake effect while ensuring the air intake volume of the air conditioner.

[0079] Further, in some possible implementation manners, the indoor heat exchanger 500 is arranged corresponding to the indoor air inlet 101 front and back.

[0080] The air conditioner further includes an air duct component 300. The air duct component 300 is disposed inside the cabinet 100 and defines a body housing passage 400 with the cabinet 100. An upper air duct 101, a centrifugal air duct 302, and a lower air duct 303 are formed inside the air duct component 300 and are connected in sequence up and down. An air duct inlet communicating with the body housing passage 400 and the centrifugal air duct 302 is formed on the surface. The air duct component further includes a second centrifugal fan 304 arranged in the centrifugal air duct 302. The air inlet of the second centrifugal fan 304 communicates with the indoor air inlet through the body housing passage 400, and the air outlet communicates with the indoor upper air outlet 102 and the indoor lower air outlet 103.

[0081] Wherein, a fresh air component installation space located at the rear side of the cabinet 100 is defined among the bottom of the indoor heat exchanger 500, the rear part of the air duct component 300, and the bottom of the cabinet 100.

[0082] Wherein, the fresh air component 200 is installed in the fresh air component installation space.

[0083] The fresh air component 200 in the embodiment of the present application makes full use of the space among the air duct component 300, the indoor heat exchanger 500, and the cabinet 100 to arrange the fresh air component 200. Thus, on the one hand, the air intake volume of the air conditioner is ensured, and on the other hand, the overall size of the air conditioner will not be increased.

[0084] Further, in some possible embodiments, an auxiliary air inlet 106 is further provided at the rear of the housing 100, with one side communicating with the indoor environment and the other side communicating with the air inlet of the first centrifugal fan 201. The auxiliary air inlet 106 is provided below the indoor air inlet 101;

[0085] Among them, the indoor air flow entering the first centrifugal fan 201 through the auxiliary air inlet 106 can be mixed with the indoor air flow entering the first centrifugal fan 201 through the fresh air inlet 104, and is discharged into the room from the fresh air outlet 105.

[0086] In the embodiment of the present application, by adding the auxiliary air inlet 106, the circulation volume of the indoor air can be further increased. The auxiliary air inlet 106 directly communicates with the indoor environment, enabling the indoor air to directly enter the first centrifugal fan 201, enhancing the fluidity of the indoor air. At the same time, when the air conditioner is heating, the heating air flow through the indoor lower air outlet 103 of the air conditioner can enter the fresh air assembly 200 through the auxiliary air inlet 106, while the outdoor fresh air enters the fresh air assembly 200 through the fresh air inlet 104. The mixing of the two air flows can greatly reduce the problem of the temperature difference between the indoor and outdoor fresh air, improving the comfort when the air conditioner blows air.

[0087] Further, in some possible embodiments, the first centrifugal fan 201 is a double-suction and double-discharge centrifugal fan with two air inlets and two air outlets;

[0088] Among them

[0089] Two auxiliary air inlets 106 are provided at the rear of the housing 100 and are spaced apart in the vertical direction of the housing 100. Each auxiliary air inlet 106 correspondingly communicates with one air inlet of the first centrifugal fan 201; and

[0090] Two fresh air outlets 105 are further provided at the rear of the housing 100 and are spaced apart in the circumferential direction of the housing 100. Each fresh air outlet 105 correspondingly communicates with one air outlet of the first centrifugal fan 201.

[0091] The first centrifugal fan 201 in the embodiment of the present application is a double-suction and double-outlet centrifugal fan. This design can significantly increase the air volume. The two air inlets and two air outlets can work simultaneously, increasing the air flow rate and improving the working efficiency of the air conditioner. The two auxiliary air inlets 106 and two fresh air outlets 105 spaced apart at the rear of the casing 100 can make the air flow evenly distributed inside the air conditioner, thereby improving the uniformity and efficiency of air circulation. Since the double-suction and double-outlet design can increase the air volume without requiring too high a rotational speed, it is possible to reduce noise and energy consumption and improve the energy efficiency ratio of the air conditioner. The larger air volume and more uniform air flow distribution can adjust the indoor temperature faster, improve the comfort of users, and can respond more quickly to changes in indoor temperature.

[0092] It should be noted that although the number of air inlets and air outlets is increased, due to the design of the double-suction and double-outlet centrifugal fan, the overall structure can still remain compact while maintaining the aesthetics of the casing 100.

[0093] Further, in some possible implementation manners, the two fresh air outlets 105 are disposed between the two auxiliary air inlets 106 distributed vertically;

[0094] The upper auxiliary air inlet 106 among them includes an upper auxiliary air inlet A1061 and an upper auxiliary air inlet B1062 spaced apart in the circumferential direction of the casing, and the fresh air inlet 104 is disposed between the upper auxiliary air inlet A1061 and the upper auxiliary air inlet B1062 distributed along the circumferential direction of the casing.

[0095] In the embodiment of the present application, the two fresh air outlets 105 are disposed between the two auxiliary air inlets 106 distributed vertically. This vertical layout helps to achieve the up-and-down circulation of indoor air, enhance the three-dimensional sense of air flow, and improve the air exchange efficiency. The design of the vertically distributed auxiliary air inlets and fresh air outlets forms symmetry visually, enhancing the aesthetics of the air conditioner.

[0096] Further, in some possible implementation manners, the fresh air assembly 200 further includes:

[0097] A flow path control structure 203, and the flow path control mechanism 203 is used to control the opening and closing of the fresh air inlet 104.

[0098] In the embodiment of the present application, the flow path control structure 203 allows for precise control of the opening and closing of the fresh air inlet 104, which means that the fresh air volume can be adjusted according to indoor and outdoor environmental conditions and user needs, optimizing the indoor air quality. By controlling the opening and closing of the fresh air inlet 104, the introduction of fresh air can be reduced or stopped when a large amount of fresh air is not required, thereby reducing energy consumption and improving the energy efficiency ratio of the air conditioner. Users can adjust the fresh air volume through the flow path control structure 203 according to personal preferences and indoor environmental needs to enhance comfort. For example, increase the fresh air volume in case of poor air quality and reduce the fresh air volume when the air quality is good. Preferably, the above-mentioned flow path control mechanism is an air inlet baffle rotatably arranged at the fresh air inlet 104.

[0099] Further, in some possible implementation manners, the fresh air assembly 200 further includes an air auxiliary treatment module 202 disposed on the air inlet path of the first centrifugal fan 201, and the air auxiliary treatment module 202 is used for auxiliary treatment of the air flow inhaled into the first centrifugal fan 201;

[0100] Wherein the air auxiliary treatment module 202 at least includes an air purification module.

[0101] The air auxiliary treatment module 202 in the embodiment of the present application at least includes an air purification module, which means that the air conditioner can purify the inhaled air, remove pollutants, bacteria, viruses, etc. in the air, and improve the indoor air quality. Through the air purification module, the air conditioner can reduce harmful substances in the indoor air, provide a healthier indoor environment for users, and is particularly beneficial to people with allergic constitutions or sensitive respiratory systems. At the same time, the purification module can reduce the damage of dust and other particulate matters to the internal components of the air conditioner, thereby reducing the maintenance cost and extending the service life of the air conditioner. Preferably, the above-mentioned air purification module is a filter net module.

[0102] Further, in some possible implementation manners, an installation port 107 is provided at the rear of the housing 100, and the air auxiliary treatment module 202 can be detachably installed on the air inlet path of the first centrifugal fan 201 through the installation port 107;

[0103] Wherein the installation port 107 is disposed on both sides or one side of the center position at the rear of the housing 100, and the air auxiliary treatment module 202 installed in the fresh air assembly 200 through the installation port 107 is located above and / or below the rotation axis of the first centrifugal fan 201.

[0104] In the embodiment of the present application, an installation opening 107 is provided at the rear of the housing 100, enabling the air-assisted processing module 202 to be disassembled and installed through this opening, greatly facilitating the maintenance and replacement of the module. Users can easily disassemble the air-assisted processing module 202 for cleaning or replacing the filter screen, etc., without the need for professional tools or technicians, improving the convenience for users. The design of the installation opening 107 embodies the modular concept, making the air-assisted processing module 202 an independent module that can be upgraded or replaced as needed, enhancing the flexibility of the design.

[0105] Meanwhile, the air-assisted processing module 202 is located above and below the axis of rotation of the fan blade and is parallel to the ground. Preferably, there are four installation openings 107, and the four installation openings 107 are distributed at the upper, lower, left, and right positions on the rear side of the rear housing 1b. Correspondingly, there are also four air-assisted processing modules 202. When the four air-assisted processing modules 202 are installed in the fresh air component 200 through the four installation openings 107, the four air-assisted processing modules 202 are distributed at the upper, lower, left, and right positions on the rear side of the rear housing 1b, thus ensuring smooth disassembly and assembly even in a narrow space and facilitating users to replace. This avoids the serious consequence that the air-assisted processing module 202 cannot be replaced when there is no space to extract the air-assisted processing module 202 when the air conditioner is against the wall.

[0106] Furthermore, in some possible implementation manners, the first centrifugal fan 201 includes:

[0107] A fan volute, on the surface of which there are two air inlets and two air outlets, and inside which there is a blade installation cavity 204 and two air ducts 205;

[0108] A centrifugal fan blade 2c and a blade motor 2d, the centrifugal fan blade 2c is installed in the blade installation cavity 204, and the rotation axis of the blade motor 2d is arranged along the vertical direction of the housing 100;

[0109] Wherein the two air inlets of the first centrifugal fan are correspondingly arranged on both axial sides of the centrifugal fan blade 2c, and the two air outlets of the first centrifugal fan are correspondingly communicated with the two air ducts 205.

[0110] Furthermore, in some possible implementation manners, the air duct 205 is designed as a gradually expanding air duct from the side close to the blade installation cavity 204 to the side far from the blade installation cavity 204.

[0111] In the embodiment of the present application, the air outlet duct 205 is designed as a gradually expanding duct from the side close to the impeller installation cavity 204 to the side far from the impeller installation cavity 204, which can reduce the air resistance. Because when the air flow gradually accelerates in the duct, the increase in the cross-sectional area of the duct can reduce the turbulence and eddy current of the air flow, thereby reducing the noise. At the same time, the gradually expanding duct can more effectively guide the air flow, reduce the energy loss, thereby improving the air volume and air speed, and enhancing the refrigeration and heating effects of the air conditioner.

[0112] Further, in some possible implementation manners, the blower housing includes a housing 2a and a housing cover 2b that are butt-jointed and fitted together. A housing installation position for installing the air auxiliary treatment module 202 is formed on the housing 2a, and a housing cover installation position for installing the air auxiliary treatment module 202 is formed on the housing cover 2b;

[0113] The fresh air assembly 200 further includes a plurality of air auxiliary treatment modules 202, and a part of the air auxiliary treatment modules 202 are detachably installed in the housing installation position, and another part of the air auxiliary treatment modules 202 are detachably installed in the housing cover installation position;

[0114] The air auxiliary treatment module 202 at least includes an air purification module.

[0115] In the embodiment of the present application, the blower housing is composed of a housing 2a and a housing cover 2b. This modular design makes the installation and disassembly of the air auxiliary treatment module 202 more convenient, and improves the convenience of maintenance and upgrade. A plurality of air auxiliary treatment modules 202 can be respectively installed in the housing installation position and the housing cover installation position. This design provides flexible air treatment capabilities and allows adding, reducing or replacing modules as needed. The air auxiliary treatment module 202 at least includes an air purification module, and this design can more effectively purify the air and improve the indoor air quality.

[0116] Further, in some possible implementation manners, the air auxiliary treatment module 202 includes a mounting bracket 2021 and a module body 2022, and the module body 2022 is detachably installed in the housing installation position and the housing cover installation position through the mounting bracket 2021.

[0117] In the embodiment of the present application, the air-assisted processing module 202 is detachably installed through the mounting bracket 2021, which makes the installation and disassembly process of the module more convenient, without complex operations or tools. The design of the mounting bracket 2021 enables the module body 2022 to be accurately installed in a predetermined position, optimizing the space utilization in the volute and the volute cover. At the same time, the mounting bracket 2021 provides additional protection for the module body 2022, reducing damage that may be caused by direct contact or impact, and extending the service life of the module. Preferably, the above-mentioned mounting bracket 2021 is a filter screen bracket, and the above-mentioned module body is a filter screen. A slide rail is provided at the installation position of the volute, and the filter screen bracket can be detachably assembled with the volute through the slide rail.

[0118] Further, in some possible implementation manners, the rotating shaft of the second centrifugal fan is arranged along the horizontal direction of the casing 100, and the second centrifugal fan 304 is a double-suction centrifugal fan having at least one air inlet and two air outlets;

[0119] Wherein the air inlet of the second centrifugal fan 304 is connected to the air duct inlet of the air duct component 300, one of the air outlets of the second centrifugal fan 304 is connected to the upper air duct 301, and the other air outlet is connected to the lower air duct 303. The upper air duct 301 is connected to the indoor upper air outlet 102, and the lower air duct 303 is connected to the indoor lower air outlet 103.

[0120] Further, in some possible implementation manners, as Figure 1 shown, the casing 100 includes a front casing 1a and a rear casing 1b. The front casing 1a and the rear casing 1b are assembled together front and back to form the casing 100. An indoor air inlet 101, a fresh air inlet 104, a fresh air outlet 105, and an auxiliary air inlet 106 communicating with the fresh air component are formed on the rear casing 1b;

[0121] The air conditioner further includes:

[0122] An upper air outlet frame component 600 and a lower air outlet frame component 700. The upper air outlet frame component 600 is arranged between the upper air duct 301 and the indoor upper air outlet 102 to connect the upper air duct 301 and the indoor upper air outlet 102. The lower air outlet frame component 700 is arranged between the lower air duct 303 and the indoor lower air outlet 103 to connect the lower air duct 303 and the indoor lower air outlet 103;

[0123] A chassis component 800, and the chassis component 800 is arranged at the bottom of the casing 100.

[0124] In order to more clearly understand the structure and working principle of the air conditioner in the embodiment of the present application, the following will be specifically described in conjunction with Figures 1 - 8 For specific illustration:

[0125] From Figure 1As shown in the figure, the fresh air component 200 is located vertically between the indoor heat exchanger 500 and the chassis component 800, and horizontally between the air inlet panel (i.e., the rear shell 1b) and the lower air outlet frame component 700, occupying a relatively small space. The fresh air component 200 and the indoor heat exchanger 500 are fixedly installed on both sides of the air inlet panel through pin holes and screws; the upper air outlet frame component 600, the air duct component 300, and the lower air outlet frame component 700 form the entire heat exchange channel, which is also fixedly installed on both sides of the air inlet panel through pin holes and screws, clamping the indoor heat exchanger 500 and the fresh air component 200 in the middle; finally, the decorative panel component (i.e., the front shell 1a) is buckled on the air inlet panel (i.e., the rear shell 1b) to cover the left and right side structures and beautify the appearance.

[0126] As Figure 6 shown, the fresh air component includes a volute 2a, a volute cover 2b, a filter screen bracket, a filter module, a centrifugal impeller 2c, an impeller motor 2d, and an air inlet baffle. The rotation axis of the double-suction centrifugal impeller is perpendicular to the ground. This design can make the fresh air volute profile parallel to the ground, enabling the fresh air component 200 to achieve a flat design and greatly reducing the occupied space. The space released in the vertical direction can be designed as the indoor air inlet 101 for indoor air. By increasing the intake of indoor air, the effect of accelerating the purification of indoor air can be achieved.

[0127] As Figures 3 - 5 shown, the rotation axis of the double-suction centrifugal impeller of the air duct component 300 is parallel to the ground (the rotation axis is from left to right). Its layout can make the heated air flow out in the vertical direction. Under the action of the air duct impeller, the air flow enters from the upper rear grille, exchanges heat through the indoor heat exchanger 500, and blows out the heating air flow from the upper and lower sides of the air duct. Since the indoor lower air outlet 103 is relatively low, its air flow is easily attracted by the fresh air component 200. Under the action of the impeller, part of the indoor air enters through the indoor air inlet 101 on the upper side of the air inlet panel (i.e., the rear shell 1b), and another part of the air enters the fresh air component 200 through the auxiliary air inlet 106 on the lower side of the air inlet panel (i.e., the rear shell 1b). When the air inlet baffle (i.e., the above-mentioned flow path control mechanism 203) at the fresh air inlet 104 on the air inlet panel (i.e., the rear shell 1b) is in the open state, outdoor fresh air enters the whole machine fresh air component 200 through the fresh air inlet 104. The indoor and outdoor air flows are fully mixed in the fresh air component 200, greatly reducing the temperature difference between the internal and external gases, improving comfort, and also reducing the condensation problem caused by the large temperature difference between the internal and external. When the baffle on the air inlet panel is in the closed state, indoor fresh air enters through the auxiliary air inlets 106 on the upper and lower sides of the air inlet panel, passes through the filter module, and flows out from both sides of the whole machine. Entering from two directions and flowing out from two directions greatly improves the air filtration efficiency, enabling users to experience fresh and clean air faster.

[0128] As Figure 2 and Figure 8As shown in the figure, the purification module is placed above and below the rotating shaft of the centrifugal fan blade 2c in the fresh air component 200. When the user needs to replace the purification module, the filter screen bracket can be horizontally pulled out. The filter bracket is separated into two equal parts left and right, reducing the disassembly and assembly travel and preventing the situation where there is no space to pull out when the air conditioner is against the wall, which may cause the serious consequence that the purification module cannot be replaced. The filter screen bracket is slid into the tracks of the volute or the volute cover from both left and right sides. The tracks effectively limit the degrees of freedom of the filter screens in the up-down and left-right directions, facilitating the user's operation.

[0129] As Figure 5 and Figure 7 shown in the figure, the volute 2a and the volute cover 2b have a complete streamline and a smooth transition without convex structures, greatly reducing the wind resistance. At the same time, it avoids the formation of eddy currents caused by convex structures, resulting in air volume loss. The air outlets on both left and right sides are in the shape of a flared mouth, further reducing the wind resistance and increasing the air volume. The flared mouth design maximizes the air outlet area, which is a necessary and sufficient condition for increasing the fresh air volume, enabling the fresh air to quickly diffuse in the room. This structural design can effectively avoid the "whistling sound" {if the air outlet is in a contracted state, high-speed air flow passing through a narrow channel forms a sound similar to whistling}, reducing the noise impact. At the same time, by increasing the motor speed, the fresh air volume can be further increased. The fresh air component 200 is provided with a total of six air outlets. The fresh air outlets 105 are distributed at the middle horizontal grille positions on both sides. The air flows out from both sides, making the fresh air diffuse more evenly in the room and improving the comfort. Outdoor fresh air enters through the round-hole-shaped fresh air inlet 104 via the fresh air duct, and indoor air enters through the annular auxiliary air inlet 106 on the side and below the fresh air inlet 104. Multiple air inlets and a relatively large air inlet area are another prerequisite for effectively increasing the fresh air volume.
