The related home air conditioners mostly adopt the split structure of indoor and outdoor units. Whether it is a bedroom or a living room, a special outdoor space is required to install the outdoor unit to match the indoor unit installed in the bedroom or living room. There is usually no such installation space outside the kitchen.

The embodiment of the present application provides an integrated air conditioner. The air conditioner does not have an outdoor unit, and therefore does not need to occupy additional outdoor space, so that the air conditioner can be applied to a kitchen environment to eliminate the discomfort caused by the high temperature and sweltering heat in the summer kitchen. It is easy to understand that in addition to being applicable to a kitchen, the air conditioner can also be applied to other environments. There are no restrictions here.

1 to 6, 7 to 11, 12, 13 to 16, and 17 show specific structures of the

air conditioners

100, 200, 300, 400, and 500 according to various embodiments of the present application. In the following, the air conditioner 100 shown in FIG. 1 to FIG. 6 is mainly used, and if necessary, the specific implementation of the air conditioner of the present application will be described in combination with other drawings.

The air conditioner in the embodiment of the present application may include a casing 20 and an air chamber 30 located in the casing 20, a first heat exchanger 60, a first fan 70, a second heat exchanger 80, a second fan 90, a compressor 50, and a node. Stream element 11.

The housing 20 may include a bottom wall 25 and a side wall 23 extending upward from an outer edge of the bottom wall 25, and the bottom wall 25 and the side wall 23 may collectively surround a storage space. The air chamber 30, the first heat exchanger 60, the first fan 70, the second heat exchanger 80, the second fan 90, the compressor 50, the throttle element 11 and the like are all formed or installed in the storage space. In the embodiments shown in the figures, the housing 20 is generally rectangular parallelepiped, the bottom wall 25 is generally square, and the side wall 23 includes a first side wall 232, a second side wall 234, a third side wall 236, and a first side wall connected end to end. Four side walls 238. The first side wall 232, the second side wall 234, the third side wall 236, and the fourth side wall 238 form a quadrangle. The side where the first side wall 232 is located can be regarded as the side wall 23 or the first side of the housing 20, the side where the second side wall 234 is located can be regarded as the second side of the side wall 23 and the housing 20, and the third side The side where the side wall 236 is located can be regarded as the third side of the side wall 23 or the housing 20, and the side where the fourth side wall 238 is located can be regarded as the fourth side of the side wall 23 or the housing 20. After being installed in place, each side (first side, second side, third side, and fourth side) of the housing 20 may face or face the four side walls of a room (eg, a kitchen), respectively.

In other embodiments, the housing 20 may have other shapes, such as a hollow cylindrical shape. When the casing 20 is cylindrical, the side wall 23 is circular and the bottom wall 25 is circular. There are no restrictions here.

It should be noted that a part of the side wall 23 of the casing 20 may be served by a side wall of the room.

The air conditioner can be installed on a wall or a ceiling of a room such as a kitchen. Most common rooms, including the kitchen, usually include four side walls. Of the four side walls, there are usually three internal walls and one external wall. During installation, the four side walls of the air-conditioning casing 20 may face each other or face a side wall of the room.

For example, the air conditioner may be placed between the decorative panel C of the ceiling and the ceiling wall of the kitchen. The upper end of the side wall 23 may be adjacent to or abut the lower surface of the kitchen top wall, and the lower surface of the bottom wall 25 may be adjacent or abut the upper surface of the decorative panel C. If necessary, fixing members such as screws may be provided between the housing 20 and the kitchen top wall and the decorative panel C to lock them securely.

The decorative panel C and the bottom wall 25 may be provided with an air vent 16 as a passage for air exchange between the air conditioner and the kitchen. The tuyere 16 may be a through hole opened in the bottom wall 25 and a through hole opened in the decorative plate C. The air outlet of the first fan 70 can communicate with the air outlet 16. In the above installation method, the air conditioner is installed in the kitchen ceiling, and only the air outlet 16 is exposed outside, which does not occupy the kitchen space and does not affect the overall aesthetics of the kitchen.

The first side wall 232 may have two

openings

13 and 15, and one of the openings 13 (also referred to as a first opening) may serve as a passage for outdoor air to enter the air conditioner. In other embodiments, the opening 13 can also serve as a passage for the air (indoor gas) in other rooms outside the room where the air conditioner enters the air conditioner. Using indoor air as the air intake of an air conditioner is beneficial to improving the heat exchange efficiency of the air conditioner.

The other opening 15 (also referred to as a second opening) can serve as a passage for the air in the air conditioner to be discharged to the outside. The

openings

13, 15 may be circular holes, square holes, or the like. The height of the opening 13 as the air inlet may be smaller than the height of the opening 15 as the air outlet.

During installation, the side wall 23 (for example, the first side wall 232) where the

openings

13 and 15 are located may face or face the external wall of the kitchen. An air inlet and an air outlet can be opened on the outer wall of the kitchen, and the air inlet can be connected with the opening 13 through an air pipe, and the air outlet can be connected with the opening 15. Since most kitchens have only one exterior wall, the opening 13 as an air inlet and the opening 15 as an air outlet are provided on the same side wall 232 of the housing 20, which is beneficial to the simplification of the air duct structure.

Commonly used ceiling decoration board sizes (width * length) are 300mm (mm) * 300mm (mm), 300mm * 600mm, 600mm * 600mm, etc. As shown in the figure, the bottom wall 25 of the air-conditioning casing 20 has a rectangular design, and the length and width dimensions are less than 600mm * 600mm, and can be matched with one or more decorative plates C during installation. The height of the housing 20 is less than the height of the suspended ceiling, which meets the installation requirements.

The housing 20 may further include a top wall that may substantially close the storage space. In other embodiments, the top wall may not be provided, as long as the airtightness of the main components in the casing 20 can be ensured.

The storage space in the casing 20 may be roughly divided into four regions: a first region 120 to a fourth region 180. The four regions may be arranged in a 2 × 2 matrix. Each area can occupy about a quarter of the space of the storage. In other embodiments, the areas occupied by the respective regions may not be substantially equal, but may be set as required. The first region 120 and the fourth region 180 may be disposed diagonally, and the second region 140 and the third region 160 may be disposed diagonally. Among them, the air chamber 30 may be mainly provided in the first area 120, the first heat exchanger 60 and the first fan 70 may be mainly provided in the second area 140, and the second heat exchanger 80 and the second fan 90 may be mainly provided In the third region 160, the compressor 50 may be mainly disposed in the fourth region 180.

The first heat exchanger 60 and the first fan 70 may be disposed on a first side of the air chamber 30 and arranged along a length direction of the second side wall 234. The first heat exchanger 60 may be provided with a passage through which a refrigerant (for example, R113, R114, R115, R134a, R502, R22, etc.) can flow. An air passage through which air can flow is formed on a peripheral side of the passage. The air in the air channel and the refrigerant in the channel can be separated by the wall of the channel. The air in the air passage can exchange heat with the refrigerant in the passage through the wall of the passage of the first heat exchanger 60. The air passage at the first heat exchanger 60 can communicate with the air chamber 30, so that air can flow freely between the air chamber 30 and the air passage at the first heat exchanger 60. In the cooling mode, the first heat exchanger 60 can function as an evaporator.

The first heat exchanger 60 may be a multi-channel heat exchanger. For example, it can be a copper tube fin heat exchanger or a micro-channel heat exchanger with flat tubes and headers. The use of micro-channel heat exchangers is conducive to reducing the weight and size of air conditioners. Among them, the flat tube is usually provided with a plurality of channels through which the refrigerant flows. Adjacent channels are isolated from each other. Multiple channels line up and affect the width of the flat tube. The flat tube is flat as a whole, its length is greater than its width, and its width is greater than its thickness. The length direction of the flat tube is the refrigerant flow direction determined by the channels in the flat tube. The length direction of the flat tube may be a straight type, a folded line type, or a curved type. The flat tube mentioned here is not limited to this type, and may be other forms. For example, adjacent channels may not be completely isolated. For another example, all the channels can be arranged in two rows as long as the width is still greater than the thickness.

The first heat exchanger 60 may be substantially plate-shaped, and has a length direction, a width direction, and a thickness direction. The dimension T1 of the first heat exchanger 60 in the thickness direction is smaller than the dimension L1 of the first heat exchanger 60 in the length direction and the dimension W1 in the width direction. The extending direction of the air passage through which air can pass is substantially the same as the thickness direction of the first heat exchanger 60. That is, the air passes through the first heat exchanger 60 substantially along the thickness direction of the first heat exchanger 60.

The first fan 70 is used to provide a force for air flowing from the air chamber 30 to the first heat exchanger 60. The first fan 70 may include a volute 72, and an impeller and an air inlet may be disposed at a center of the volute 72. An air passage inside the volute 72 is provided around the rotation axis of the impeller.

The first fan 70 may be disposed vertically. Correspondingly, the rotation axis of the impeller is set horizontally. The air inlet of the first fan 70 faces the first heat exchanger 60, and the air outlet of the first fan 70 may face the bottom wall 25. In other embodiments, the air outlet of the first fan 70 may not face the bottom wall 25 but face other directions. For example, in the air conditioner 500 shown in FIG. 17, the air outlet of the first fan 70 disposed vertically faces the fourth side wall 238. An air pipe 71 may be provided between the air outlet 16 and the air outlet of the first fan 70 so that the gas discharged from the first fan 70 can reach the air outlet 16 sufficiently and quickly. The above-mentioned installation manner of the first fan 70 and the installation of the air pipe 71 greatly increase the settable area of the air outlet 16 on the bottom wall 25.

In order to facilitate the connection between the air pipe 71 and the air outlet 16 and / or the connection between the air pipe 71 and the air outlet of the first fan 70, a connecting member 713 may be provided at the air outlet 16 and / or the air outlet of the first fan 70. The shape of the first end of the connecting piece 713 matches the shape of the air outlet 16 and / or the air outlet of the first fan 70 (for example, may be all rectangular), and is air-tightly connected to the air outlet 16 and / or the air outlet of the first fan 70 The shape of the second end of the connecting member 713 matches the shape of the air pipe 71 (for example, may be all circular), and is air-tightly connected to the air pipe 71. A middle portion of the connecting member 713 is gradually changed, and the first end and the second end of the connecting member 713 are connected.

In other embodiments, the first fan 70 may be disposed horizontally, and correspondingly, the rotation axis of the impeller is vertically disposed. Correspondingly, the air inlet of the first fan 70 faces upward and communicates with the air channel of the first heat exchanger 60; the air outlet of the first fan 70 may face the second side wall 234 or the third side wall 236.

After the first fan 70 is turned on, outdoor air can continuously flow from the opening 13 to the air chamber 30, and then from the air chamber 30 to the air passage of the first heat exchanger 60. The air in the air channel may be cooled and cooled by the refrigerant in the first heat exchanger 60 to form cold air. After leaving the air duct of the first heat exchanger 60, the cold air can be delivered to the kitchen through the first fan 70 and the air outlet 16 in this order.

Since the first heat exchanger 60 uses outdoor air intake, in order to ensure a certain pressure head and air supply distance, the first fan 70 may use a centrifugal fan.

A connection member 170 may be provided between the first heat exchanger 60 and the first fan 70. The connecting member 170 may be in a shell shape. The first end of the connecting piece 170 is arranged around the first heat exchanger 60, and the second end of the connecting piece 170 is arranged around the air inlet of the first fan 70, so that the air leaving from the air passage of the first heat exchanger 60 can completely enter First fan 70.

Since the size of the first heat exchanger 60 is larger than the size of the air inlet of the first fan 70, the size of the first end of the connecting piece 170 is larger than the size of the second end of the connecting piece 170. From the first end to the second end of the connecting member 170, the connecting member 170 tends to narrow gradually.

Of course, the connection member 170 as described above may not be provided between the first heat exchanger 60 and the first fan 70, but the first heat exchanger 60 and the first fan 70 may be separated by an isolation structure (for example, a partition plate). The gas environment is spaced from the gas environment where the second heat exchanger 80 and the second fan 90 are located to ensure that hot and cold air does not mix.

A liquid collecting pan 40 may be provided below the first heat exchanger 60. During the process of cooling and cooling the air in the air passage by the refrigerant in the first heat exchanger 60, there is a possibility that condensed water may condense on the surface of the first heat exchanger 60. The liquid collecting pan 40 disposed under the first heat exchanger 60 can collect the condensed water well. The liquid collecting tray 40 may be provided with a liquid discharge hole 18. A liquid discharge pipe 19 may be provided below the liquid collecting pan 40. The first end of the liquid discharge pipe 19 is connected to the liquid collecting pan 40 at the liquid discharge hole 18, and the second end of the liquid discharge pipe 19 projects outward through the opening 13 of the side wall 232. The height of the drain pipe 19 is lower than or not higher than the lower surface of the liquid collecting pan 40. The height of the first end of the liquid discharging pipe 19 is greater than the height of the second end of the liquid collecting pipe 19 and is collected in the liquid collecting pan 40. The condensed water can be automatically discharged to the outside through the drain hole 18 and the drain pipe 19. The air inlet is set on the lower side of the box, and the water receiving tray has a certain installation height.

The temperature of the condensed water in the drain pipe 19 is lower than the temperature of the air entering the air chamber 30 through the opening 13. The air at the opening 13 and the air chamber 30 can exchange heat with the condensed water in the drain pipe 19 and be cooled, which is beneficial to improve the cooling efficiency of the system. The contact area between the liquid discharge pipe 19 and the air can be increased by increasing the number of the liquid discharge pipes 19 arranged side by side and / or increasing the diameter of a single liquid discharge pipe 19, thereby further improving the cooling efficiency of the system.

The second heat exchanger 80 and the second fan 90 may be disposed on the second side of the air chamber 30 and arranged along the length direction of the first side wall 232. The second heat exchanger 80 may be provided with a passage through which a refrigerant can flow. An air passage through which air can flow is formed on a peripheral side of the passage. The air in the air channel and the refrigerant in the channel can be separated by the wall of the channel. The air in the air passage can exchange heat with the refrigerant in the passage through the wall of the passage of the second heat exchanger 80. The air passage at the second heat exchanger 80 can communicate with the air chamber 30, so that air can flow freely between the air chamber 30 and the air passage at the second heat exchanger 80. In the cooling mode, the second heat exchanger 80 can function as a condenser.

The second heat exchanger 80 may be a multi-channel heat exchanger. For example, it can be a copper tube fin heat exchanger or a micro-channel heat exchanger with flat tubes and headers. The use of micro-channel heat exchangers is conducive to reducing the weight and size of air conditioners. Among them, the flat tube is usually provided with a plurality of channels through which the refrigerant flows. Adjacent channels are isolated from each other. Multiple channels line up and affect the width of the flat tube. The flat tube is flat as a whole, its length is greater than its width, and its width is greater than its thickness. The length direction of the flat tube is the refrigerant flow direction determined by the channels in the flat tube. The length direction of the flat tube may be a straight type, a folded line type, or a curved type. The flat tube mentioned here is not limited to this type, and may be other forms. For example, adjacent channels may not be completely isolated. For another example, all the channels can be arranged in two rows as long as the width is still greater than the thickness.

The second heat exchanger 80 may be substantially plate-shaped, and has a length direction, a width direction, and a thickness direction. The dimension T2 of the second heat exchanger 80 in the thickness direction is smaller than the dimension L2 of the second heat exchanger 80 in the length direction and the dimension W2 in the width direction. The extending direction of the air passage through which air can pass is substantially the same as the thickness direction of the second heat exchanger 80. That is, the air passes through the second heat exchanger 80 substantially along the thickness direction of the second heat exchanger 80.

The second fan 90 is used to provide a force for air to flow from the air chamber 30 to the second heat exchanger 80. The second fan 90 may include a volute 92, and an impeller and an air inlet may be disposed at a center of the volute 92. The air passage inside the volute 92 surrounds the rotating shaft of the impeller.

The second fan 90 may be vertically arranged. Correspondingly, the rotation axis of the impeller is set horizontally. The air inlet of the second fan 90 faces the second heat exchanger 80, and the air outlet of the second fan 90 may face the first side wall 232.

Of course, the second fan 90 may also be horizontally arranged, and correspondingly, the rotating shaft of the impeller is vertically arranged. The air inlet of the second fan 90 may face upward, and the air outlet of the second fan 90 faces the first side wall 232 or the fourth side wall 238.

After the second fan 90 is turned on, the outdoor air can continuously flow from the opening 13 to the air chamber 30, and then from the air chamber 30 to the air passage of the second heat exchanger 80. The air in the air channel can be heated and heated by the refrigerant in the second heat exchanger 80 to form hot air. After leaving the air channel of the second heat exchanger 80, the hot air can be discharged to the outside through the second fan 90 and the opening 15 in this order.

Since the second heat exchanger 80 uses outdoor air inlet, in order to ensure a certain pressure head and air supply distance, the second fan 90 may use a centrifugal fan.

Compared with the bedroom and living room, the kitchen generally has heavy oil fume and harsh environment. If the first heat exchanger and / or the second heat exchanger in the air conditioner adopts an internal circulation method, after a long-term operation, a large amount of oil fume will adhere to the surface of the first heat exchanger and / or the second heat exchanger, which in turn will cause As a result, the heat transfer of the first heat exchanger and / or the second heat exchanger is deteriorated, the air conditioning operation efficiency is reduced, and the service life is reduced. The air conditioner in the embodiment of the present application adopts an external circulation mode, and the intake air of the first heat exchanger 60 and the second heat exchanger 80 is outdoor fresh air, which can effectively avoid the above-mentioned defects.

A connection member 190 may be provided between the second heat exchanger 80 and the second fan 90. The connecting member 190 may be in a shell shape. The first end of the connecting piece 190 is arranged around the second heat exchanger 80, and the second end of the connecting piece 190 is arranged around the air inlet of the second fan 90, so that the air leaving from the air passage of the second heat exchanger 80 can completely enter第二 FAN90.

Since the size of the second heat exchanger 80 is larger than the size of the air inlet of the second fan 90, the size of the first end of the connecting member 190 is larger than the size of the second end of the connecting member 190. From the first end to the second end of the connecting member 190, the connecting member 190 tends to narrow gradually.

Of course, the connection member 190 as described above may not be provided between the second heat exchanger 80 and the second fan 90, but the second heat exchanger 80 and the second fan 90 may be separated by an isolation structure (for example, a partition plate). The gas environment is spaced from the gas environment where the first heat exchanger 60 and the first fan 70 are located to ensure that hot and cold air does not mix.

The compressor 50 and the throttling element 11 may be connected to a passage inside the first heat exchanger 60 and a passage inside the second heat exchanger 80 through connection pipes P1, P2, P3, and P4 to form a refrigerant circulation path. For example, the first end of the first heat exchanger 60 may be connected to the first end of the compressor 50 through a connecting pipe P1, and the second end of the compressor 50 may be connected to the first end of the second heat exchanger 80 through a connecting pipe P2. The second end of the second heat exchanger 80 may be connected to the first end of the throttle element 11 through a connecting pipe P3, and the second end of the throttle element 11 may be connected to the first end of the first heat exchanger 60 through a connecting pipe P4. The two ends are connected.

In the cooling mode, the refrigerant is compressed by the compressor 50 and transferred to a channel inside the second heat exchanger 80 and is condensed and cooled. After the cooled refrigerant leaves the second heat exchanger 80, it will sequentially flow to the channels in the throttle element 11 and the first heat exchanger 60. The refrigerant in the first heat exchanger 60 can perform heat exchange with the air at the first heat exchanger 60, the air is cooled and cooled, and the refrigerant is heated and warmed. Then, the heated refrigerant can be returned to the compressor 50. This constitutes a refrigerant cycle.

The compressor 50 may be a horizontal compressor having a relatively short height. The use of a horizontal compressor is advantageous for reducing the height of the compressor 50, the casing 20, and the like.
