[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The air conditioner 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figures 1-3 As shown, the air conditioner 1 according to an embodiment of the present invention includes a housing, a first heat exchanger, and a first pipe assembly 30.

[0027] The housing is provided with an indoor air outlet and an air inlet area 112. The first heat exchanger is located inside the housing and is positioned opposite the air inlet area 112. Air is suitable for entering the housing from the air inlet area 112 and for exchanging heat with the first heat exchanger. The first heat exchanger can absorb heat from the air inside the housing or release heat into the air inside the housing, thereby forming cold air or hot air. The cold air or hot air flows into the room from the indoor air outlet, thereby achieving cooling or heating of the room.

[0028] The first duct assembly 30 is detachably disposed in the housing and is connected to the air intake area 112. The first duct assembly 30 is used to guide the air flowing from the air intake area 112 to the indoor air outlet, thereby realizing the smooth air intake of the air conditioner 1 in the air intake area 112.

[0029] For example, the first duct assembly 30 can be used to introduce fresh air into the air conditioner 1. Since the air conditioner 1 is installed indoors, outdoor air cannot directly enter the air conditioner 1. Therefore, the first duct assembly 30 is provided, and an air inlet pipe is connected to the first duct assembly 30. One end of the air inlet pipe is connected to the first duct assembly 30, and the other end is led to the outside, so that outdoor air can flow along the air inlet pipe to the air inlet area 112 and then enter the air conditioner 1 to introduce fresh air into the room.

[0030] The first pipe assembly 30 is detachably mounted on the housing, which facilitates flexible installation of the air conditioner 1 when the installation space is limited. For example, the housing can be installed in a designated location first, and then the first pipe assembly 30 can be installed on the housing.

[0031] Compared to installing the housing and the first pipe assembly 30 together in a designated area, installing the housing first in a designated location and then installing the first pipe assembly 30 onto the housing requires less operating space and is suitable for installation environments with limited space.

[0032] In some embodiments, the air conditioner 1 is adapted to be installed on a structural support frame on the roof of the house. The structural support frame includes a plurality of support beams extending laterally and support beams extending longitudinally, with a cutout space defined between the support beams. If the housing and the first duct assembly 30 are to be installed together through the cutout area onto the structural support frame, it may be necessary to break a portion of the support beams and enlarge a portion of the cutout area for installing the air conditioner 1 so that the air conditioner 1 can pass through the cutout area and be installed above the structural support frame.

[0033] In this embodiment, the first pipe assembly 30 is detachably mounted on the housing. This allows the housing to be first passed through the perforated area and fixed above the structural support frame, and then the first pipe assembly 30 is passed through the perforated area. Connecting the first pipe assembly 30 to the housing above the structural support frame eliminates the need to damage the structural support frame, allowing the air conditioner 1 to be fixedly installed above it, reducing installation difficulty and avoiding damage to the structural support frame.

[0034] According to the embodiment of the present utility model, the air conditioner 1 is detachably provided with the first pipe assembly 30 on the housing. This makes it convenient to flexibly install the air conditioner 1 when the installation space of the air conditioner 1 is limited. For example, the housing is first installed at a designated position, and then the first pipe assembly 30 is installed on the housing. Using this installation method, when the air conditioner 1 is installed on the structural support frame of the roof, there is no need to damage the structural support frame, which makes it easier to reduce the installation difficulty and installation cost.

[0035] The air conditioner 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the air conditioner 1 includes a housing, a first heat exchanger, and a first pipe assembly 30.

[0037] In some embodiments of this utility model, such as Figure 2 As shown, the air intake area 112 includes an indoor return air inlet 112a and an outdoor return air inlet 112b. There are two first duct assemblies 30. At least one of the indoor return air inlet 112a and the outdoor return air inlet 112b is connected to the corresponding first duct assembly 30 so as to guide indoor air to the indoor return air inlet 112a and then introduce indoor air into the air conditioner 1; and / or guide outdoor fresh air to the outdoor return air inlet 112b and then introduce outdoor fresh air into the air conditioner 1.

[0038] Specifically, if only the indoor return air vent 112a is installed, the air conditioner 1 can only circulate indoor air, and no fresh air is introduced when the air conditioner is turned on. When the air conditioner 1 is used in the kitchen, since the kitchen is a closed space and an environment that is prone to oil fumes and odors, only installing the indoor return air vent 112a to circulate the air indoors can only cool the air in the kitchen, but cannot refresh or purify the air.

[0039] If the air quality in the kitchen is already poor, such as when there is a lot of oil fumes, and only the indoor return air method is used, all the oil stains will repeatedly pass through the inside of the air conditioner 1, causing the inside of the air conditioner 1 to become dirty, and at the same time, the air quality of the air flowing out of the indoor air conditioner 1 will be poor.

[0040] Specifically, harmful substances that may be inhaled by the human body in the kitchen mainly include smoke and fumes, gas exhaust, bacteria and viruses, cleaning agents and detergents, dust and particles, etc. Being in this enclosed environment for a long time is not conducive to the health of users.

[0041] In this embodiment, outdoor air is allowed to enter the air conditioner 1 through the outdoor return air vent 112b, thereby introducing fresh air to improve indoor air quality and protect the user's health.

[0042] In some embodiments, the indoor return air vent 112a is connected to the corresponding first duct assembly 30. The air conditioner 1 also includes a first air inlet pipe, one end of which is connected to the first duct assembly 30 and the other end is led into the room. The indoor air can flow through the first air inlet pipe to the indoor return air vent 112a and enter the air conditioner 1 through the indoor return air vent 112a. After exchanging heat with the first heat exchanger in the air conditioner 1, cold air or hot air is formed. The cold air or hot air flows into the room from the indoor air outlet, thereby achieving cooling or heating of the room.

[0043] In some embodiments, the outdoor return air vent 112b is connected to the corresponding first duct assembly 30. The air conditioner 1 also includes a second air inlet pipe. One end of the second air inlet pipe is connected to the first duct assembly 30, and the other end is led to the outside. Outdoor air can flow through the second air inlet pipe to the outdoor return air vent 112b and enter the air conditioner 1 through the outdoor return air vent 112b. After exchanging heat with the first heat exchanger in the air conditioner 1, cold air or hot air is formed. The cold air or hot air flows from the indoor air outlet to the room, thereby achieving cooling or heating of the room.

[0044] In some optional embodiments of this utility model, the air conditioner 1 further includes a first baffle, which is detachably fitted with the housing. The indoor return air inlet 112a and the outdoor return air inlet 112b are respectively connected to the first duct assembly 30, thereby realizing indoor air circulation and the introduction of fresh air from the outside of the air conditioner 1.

[0045] Specifically, when it is necessary to achieve indoor air circulation and the introduction of fresh air from the outside of the air conditioner 1, the first baffle is removed from the shell, and the two first duct assemblies 30 are respectively installed at the indoor return air inlet 112a and the outdoor return air inlet 112b to achieve indoor return air and the introduction of fresh air from the outside of the air conditioner 1.

[0046] In some alternative embodiments of this utility model, one of the indoor return air vent 112a and the outdoor return air vent 112b is connected to the first duct assembly 30 and the other is blocked by a removable first baffle. In fact, when installing the air conditioner 1, the appropriate air intake method of the air conditioner 1 can be selected according to the needs.

[0047] Specifically, when the air conditioner 1 only needs indoor air circulation and does not require the introduction of fresh air from the outside, the indoor return air vent 112a can be connected to the first duct assembly 30, and the first baffle can block the outdoor return air vent 112b. In this case, it is not necessary to install the first duct assembly 30 at the outdoor return air vent 112b. Indoor air can enter the air conditioner 1 through the first duct assembly 30 and the indoor return air vent 112a, exchange heat with the first heat exchanger in the air conditioner 1, and then flow into the room from the indoor air outlet to cool or heat the room.

[0048] When the air conditioner 1 only needs to draw in fresh air from the outside and does not require indoor air circulation, the outdoor return air vent 112b can be connected to the first duct assembly 30, and the first baffle can block the indoor return air vent 112a. In this case, it is not necessary to install the first duct assembly 30 at the indoor return air vent 112a. Outdoor air can enter the air conditioner 1 through the first duct assembly 30 and the outdoor return air vent 112b, exchange heat with the first heat exchanger in the air conditioner 1, and then flow into the room from the indoor air outlet to cool or heat the room.

[0049] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the first duct assembly 30 includes a sealing connection part 31 and a first ventilation duct 32. The sealing connection part 31 is detachably disposed on the housing and covers the air inlet area 112. The sealing connection part 31 has an air passage 311. The first ventilation duct 32 is connected to the sealing connection part 31. The air passage 311 connects the air inlet area 112 and the first ventilation duct 32. Air is suitable to flow along the first ventilation duct 32 through the air passage 311 to the air inlet area 112 and enter the air conditioner 1 from the air inlet area 112.

[0050] Specifically, the first ventilation duct 32 is connected to the air passage 311, and air is suitable to flow through the first ventilation duct 32 to the air passage 311, and then enter the air conditioner 1 from the air intake area 112.

[0051] In this way, by having the sealing connection 31 cover the air intake area 112, air leakage at the air intake area 112 can be avoided.

[0052] In some optional embodiments of this utility model, the housing includes a chassis 13, a first housing portion 11 and a second housing portion 12. The first housing portion 11 and the chassis 13 together define a heat exchange cavity for accommodating a first heat exchanger. The air inlet area 112 includes an indoor return air inlet 112a and an outdoor return air inlet 112b. There are two first pipe assemblies 30. At least one of the indoor return air inlet 112a and the outdoor return air inlet 112b is provided with a first pipe assembly 30. The sealing connection portion 31 is adapted to cover the indoor return air inlet 112a and / or the outdoor return air inlet 112b.

[0053] In some embodiments, such as Figure 2 As shown, the first housing 11 defines an indoor return air vent 112a on one side in the X direction. The sealing connection 31 is adapted to cover the side of the first housing 11 on one side in the X direction, thereby covering the indoor return air vent 112a. The first ventilation duct 32 is connected to the air passage 311 on the sealing connection 31, thereby connecting the indoor return air vent 112a and the first ventilation duct 32. The indoor air is adapted to flow along the first ventilation duct 32, through the air passage 311 to the indoor return air vent 112a, and then enter the air conditioner 1 from the indoor return air vent 112a.

[0054] In some examples, a first air inlet pipe is connected to the first ventilation duct 32. One end of the first air inlet pipe is connected to the first ventilation duct 32, and the other end leads to the room so that the indoor air can flow along the first air inlet pipe to the indoor return air inlet 112a, and then flow into the air conditioner 1.

[0055] In some embodiments, such as Figure 2 As shown, the first housing 11 defines an outdoor return air vent 112b on one side in the Y direction. The sealing connection 31 is adapted to cover the side of the first housing 11 on one side in the Y direction, thereby covering the outdoor return air vent 112b. The first ventilation duct 32 is connected to the air passage 311 on the sealing connection 31, thereby connecting the outdoor return air vent 112b and the first ventilation duct 32. Outdoor air is adapted to flow along the first ventilation duct 32, through the air passage 311 to the outdoor return air vent 112b, and then enter the air conditioner 1 from the outdoor return air vent 112b.

[0056] In some examples, a second air inlet pipe is connected to the first ventilation duct 32. One end of the second air inlet pipe is connected to the first ventilation duct 32, and the other end leads to the outside, so that outdoor air can flow along the second air inlet pipe to the outdoor return air inlet 112b, and then flow into the air conditioner 1.

[0057] In some optional embodiments of this utility model, such as Figure 3 As shown, a valve 50 is provided in the first ventilation duct 32 to allow the first ventilation duct 32 to be opened or closed, thereby using the valve 50 to control the opening and closing of the air intake area 112 or to control the air intake volume at the air intake area 112.

[0058] In some embodiments, such as Figure 2 As shown, the air intake area 112 includes an indoor return air inlet 112a and an outdoor return air inlet 112b. There are two first duct assemblies 30. The first duct assembly 30 is provided in both the indoor return air inlet 112a and the outdoor return air inlet 112b. Two sealing connection parts 31 cover the indoor return air inlet 112a or the outdoor return air inlet 112b respectively. Two first ventilation ducts 32 are respectively connected to the corresponding sealing connection parts 31.

[0059] Each of the two first ventilation ducts 32 is equipped with a valve 50. By controlling the opening of the two valves 50, the air intake at the indoor return air inlet 112a and the outdoor return air inlet 112b can be controlled, thereby controlling the indoor return air volume and the outdoor fresh air volume of the air conditioner 1, and controlling the mixed air intake at different proportions at the indoor return air inlet 112a and the outdoor return air inlet 112b.

[0060] In some specific embodiments of this utility model, such as Figure 3 As shown, the air conditioner 1 also includes a motor unit 55, which is located in the first ventilation duct 32. The motor unit 55 is used to drive the valve 50 to rotate, thereby controlling the first ventilation duct 32 to open or close, controlling the opening degree of the first ventilation duct 32, and thus controlling the air intake volume at the air intake area 112.

[0061] In some embodiments, such as Figure 3 As shown, the first ventilation duct 32 has a circular cross-section, and the valve 50 is a circular valve. The motor unit 55 drives the valve 50 to rotate. Specifically, when the outer edge of the valve 50 is in contact with the inner wall of the first ventilation duct 32, the valve 50 closes the first ventilation duct 32. As the valve 50 rotates and gradually separates from the inner wall of the first ventilation duct 32, the valve 50 gradually opens the first ventilation duct 32. The degree of opening of the first ventilation duct 32 can be controlled by controlling the rotation angle of the valve 50, thereby controlling the air intake at the first ventilation duct 32.

[0062] In some embodiments, the cross-section of the first ventilation duct 32 is circular, and the valve 50 includes a first valve plate 51 and a second valve plate 52. Both the first valve plate 51 and the second valve plate 52 are semi-circular. The first valve plate 51 has a first pivot connected to the inner wall of the first ventilation duct 32, and the second valve plate 52 has a second pivot connected to the inner wall of the first ventilation duct 32.

[0063] The motor drives the first valve plate 51 and the second valve plate 52 to rotate. Specifically, when the outer edges of both the first valve plate 51 and the second valve plate 52 are in contact with the inner wall of the first ventilation duct 32, the valve 50 closes the first ventilation duct 32. As the first valve plate 51 and the second valve plate 52 rotate and gradually separate from the inner wall of the first ventilation duct 32, the first valve plate 51 and the second valve plate 52 gradually open the first ventilation duct 32. The angle at which the first valve plate 51 and the second valve plate 52 rotate can control the degree of opening of the first ventilation duct 32, thereby controlling the air intake volume at the first ventilation duct 32.

[0064] In some optional embodiments of this utility model, the sealing connection part 31 is fixed to the housing by a fixing connector so that the sealing connection part 31 can cover the air inlet area 112 and prevent the air conditioner 1 from leaking air.

[0065] In some embodiments, the fixing fastener may be a screw or bolt, and the fixing fastener passes through the sealing connection 31 and engages with the housing to detachably fix the sealing connection 31 to the housing.

[0066] In some embodiments, the first ventilation duct 32 is fixed to the sealing connection portion 31 by screws or bolts. The screws or bolts pass through the mounting ears on the outer edge of the first ventilation duct 32 and cooperate with the sealing connection portion 31 to fix the first ventilation duct 32 to the sealing connection portion 31.

[0067] In some optional embodiments of this utility model, such as Figure 1 As shown, the housing includes a chassis 13, a first shell portion 11, and a second shell portion 12. The first shell portion 11 and the second shell portion 12 are spaced apart from the chassis 13 along a first direction. A keel clearance groove 101 is defined between the first shell portion 11, the second shell portion 12, and the chassis 13. The keel clearance groove 101 is used to avoid the structural support frame of the roof, for example, to avoid a support beam extending laterally or longitudinally in the structural support frame, so that the first shell portion 11 and the second shell portion 12 can extend from two adjacent hollow areas in the structural support frame to the top of the structural support frame.

[0068] In some embodiments, the structural support frame includes multiple 300mm*300mm hollow areas, and the projected area of ​​the first shell portion 11 and the second shell portion 12 in the horizontal direction is both less than 300mm*300mm, so that the first shell portion 11 and the second shell portion 12 can extend into the space between two adjacent hollow areas.

[0069] The area of ​​the largest cross-section of the first pipe assembly 30 is less than 300mm*300mm.

[0070] Specifically, since the projected areas of the first shell portion 11 and the second shell portion 12 in the horizontal direction are both smaller than the area of ​​the hollowed-out region, both the first shell portion 11 and the second shell portion 12 can extend into the hollowed-out region. Specifically, the structural support frame includes two adjacent hollowed-out regions, and the support beam between the two connected hollowed-out regions corresponds to the keel clearance groove 101, so that the first shell portion 11 and the second shell portion 12 can respectively extend through the two adjacent hollowed-out regions to the top of the structural support frame.

[0071] Because the maximum cross-sectional area of ​​the first pipe assembly 30 is smaller than the area of ​​the perforated region, the first pipe assembly 30 can smoothly pass through the perforated region and reach the top of the structural support frame. After the housing is fixed to the structural support frame, the first pipe assembly 30 can extend from other perforated regions to the top of the structural support frame, where the connection and installation of the first pipe assembly 30 and the first housing portion 11 or the second housing portion 12 can be completed. This installation method does not require damaging the support beams of the structural support frame, simplifying the installation of the air conditioner 1, reducing the difficulty of installation, and lowering installation costs.

[0072] The first shell 11 and the chassis 13 together define a heat exchange cavity that accommodates the first heat exchanger. The indoor air outlet and the air inlet area 112 are located in the first shell 11 and are both connected to the heat exchange cavity. Air is suitable to enter the heat exchange cavity through the air inlet area 112. After the air enters the heat exchange cavity and exchanges heat with the first heat exchanger, it forms cold air or hot air. The cold air or hot air flows from the indoor air outlet to the room to cool or heat the room.

[0073] The second shell 12 and the chassis 13 together define a heat dissipation cavity and a heat dissipation port connected to the heat dissipation cavity. The air conditioner 1 also includes a second heat exchanger, which is located in the heat dissipation cavity. Outdoor air is suitable to enter the heat dissipation cavity through the heat dissipation port and exchange heat with the second heat exchanger in the heat dissipation cavity.

[0074] Specifically, the air conditioner 1 also includes a compressor and a throttling device, which is connected between the first heat exchanger and the second heat exchanger.

[0075] The refrigerant is designed to circulate between the compressor, the second heat exchanger, the throttling device, and the first heat exchanger to achieve indoor cooling. The compressor compresses the gaseous refrigerant to form a high-temperature gaseous refrigerant. When the high-temperature gaseous refrigerant flows through the second heat exchanger, it exchanges heat with the air in the heat dissipation chamber to dissipate heat into the environment, turning the refrigerant in the second heat exchanger into a medium-temperature liquid refrigerant. After flowing through the throttling device, the medium-temperature liquid refrigerant becomes a low-temperature liquid refrigerant. When the low-temperature liquid refrigerant flows through the first heat exchanger, it absorbs heat from the air in the heat exchange chamber, thus forming cold air. The cold air flows into the room from the indoor air outlet to achieve indoor cooling.

[0076] The refrigerant flowing through the first heat exchanger absorbs heat from the air and becomes a low-temperature gaseous refrigerant. The gaseous refrigerant flows to the air inlet of the compressor, thereby realizing the circulation of the refrigerant in the compressor, the second heat exchanger, the throttling device and the first heat exchanger.

[0077] Alternatively, the refrigerant circulates between the compressor, the first heat exchanger, the throttling device, and the second heat exchanger to heat the room. The compressor compresses the gaseous refrigerant to form a high-temperature gaseous refrigerant. When the high-temperature gaseous refrigerant flows through the first heat exchanger, the refrigerant in the first heat exchanger dissipates heat into the air in the heat exchange chamber, thus forming hot air. The hot air flows into the room from the indoor air outlet to heat the room. At the same time, the refrigerant flowing through the first heat exchanger becomes a medium-temperature liquid refrigerant. After flowing through the throttling device, the medium-temperature liquid refrigerant becomes a low-temperature liquid refrigerant. When the low-temperature liquid refrigerant flows through the second heat exchanger, the refrigerant in the second heat exchanger exchanges heat with the air in the heat dissipation chamber to absorb heat from the air, thus becoming a gaseous refrigerant. The gaseous refrigerant flows to the compressor inlet, thus realizing the circulation of the refrigerant within the compressor, the first heat exchanger, and the second heat exchanger.

[0078] In some embodiments, such as Figure 2 As shown, the first direction is the Y direction, the X direction is perpendicular to the Y direction, the first shell 11 and the second shell 12 are spaced apart along the Y direction on the chassis 13 (it should be understood that the above direction limitation is only for the convenience of describing the attached drawings and will not limit the actual installation position and direction of the air conditioner 1), the first shell 11, the second shell 12 and the chassis 103 define the keel avoidance groove 101.

[0079] The first housing 11 defines an outdoor return air vent 112b on the side away from the second housing 12 in the Y direction, and defines an indoor return air vent 112a on the side of the first housing 11 in the X direction. The second housing 12 defines a heat dissipation vent on the same side in the X direction.

[0080] In some embodiments, the chassis 13 is provided with an indoor air outlet, which is directly opposite the hollow area of ​​the structural support frame. The cold or hot air in the heat exchange chamber is suitable to flow into the room through the indoor air outlet and the hollow area to achieve cooling or heating of the room.

[0081] In some embodiments, the outdoor return air vent 112b is connected to the outside. This can be achieved by introducing outdoor air to the outdoor return air vent 112b through a second air inlet pipe, or by setting an outdoor connection port on the wall above the structural support frame, so that outdoor air can enter the space above the structural support frame through the outdoor connection port, and then enter the air conditioner 1 through the outdoor return air vent 112b, so as to introduce fresh air into the air conditioner 1.

[0082] In some specific embodiments of this utility model, the heat dissipation port is located on the side of the second shell 12. The second shell 12 has a detachable second baffle. The second baffle is used to open or close the heat dissipation port. When it is necessary for the heat dissipation cavity to communicate with the outside, the second baffle is removed to open the heat dissipation port, so that outside air can enter the heat dissipation cavity through the heat dissipation port, and the second heat exchanger can exchange heat with the air in the outdoor environment.

[0083] Specifically, the first shell 11 and the second shell 12 are located above the structural support frame through the hollow area of ​​the structural support frame. The heat dissipation port can be connected to the outside through the third air inlet pipe, or an outdoor connection port is provided on the wall of the space above the structural support frame so that the space above the structural support frame can be connected to the outside environment, so that the second heat exchanger in the heat dissipation cavity can exchange heat with the air in the outside environment.

[0084] In some specific embodiments of this utility model, such as Figure 2 As shown, the air conditioner 1 also includes a second ventilation duct 60, which is connected to the heat dissipation port.

[0085] When it is necessary to connect the second ventilation duct 60 to the second housing 12, the second baffle on the second housing 12 can be removed first, and then the second ventilation duct 60 can be connected to the second housing 12 so that the second ventilation duct 60 connects to the heat dissipation port and the outside.

[0086] In some embodiments, the second ventilation duct 60 is fixed to the second housing 12 by screws or bolts.

[0087] In some embodiments, the second ventilation duct 60 is connected to the third air inlet pipe. One end of the third air inlet pipe is connected to the second ventilation duct 60, and the other end is led to the outside. Outdoor air can enter the heat dissipation cavity along the third air inlet pipe so that the second heat exchanger in the heat dissipation cavity can exchange heat with the air in the environment.

[0088] In some embodiments, the first duct assembly 30 includes a first ventilation duct 32, and the first ventilation duct 32 and the second ventilation duct 60 have the same structure, which facilitates the improvement of the versatility of components, thereby reducing costs and installation difficulty.

[0089] In some examples, such as Figure 2 As shown, the second ventilation duct 60 is equipped with a valve 50 to allow the second ventilation duct 60 to be opened or closed, thereby using the valve 50 to open for heat dissipation or control the ventilation volume at the heat dissipation vent.

[0090] The air conditioner 1 also includes a motor unit 55, which is located in the second ventilation duct 60 and is used to drive the valve 50 to rotate, thereby controlling the second ventilation duct 60 to open or close, controlling the opening degree of the second ventilation duct 60, and controlling the ventilation volume at the heat dissipation vent.
