Related household air conditioners mostly adopt a split structure of an indoor unit and an outdoor unit. Whether installed in a bedroom or a living room, a special outdoor space is required for installing the outdoor unit so as to be matched with the indoor unit arranged in the bedroom or the living room. Such an installation space is not generally available outside a room such as a kitchen.

The embodiment of the application provides an integrated air conditioner. The air conditioner has no outdoor unit, thus occupying no extra outdoor space, so that the air conditioner can be applied to a kitchen environment for eliminating discomfort brought to people by kitchen high temperature sultriness in summer. It will be readily appreciated that the air conditioner may be applied to other environments besides a kitchen. And are not limited herein.

An embodiment air conditioner 100 as shown in fig. 1 and 2 may include a housing 20, and an air chamber 30, a first heat exchanger 60, a first fan 70, a second heat exchanger 80, a second fan 90, a compressor 50, and a throttling element 11 located within the housing 20.

The housing 20 may include a bottom wall 25 and a side wall 23 extending upward from the outer edge of the bottom wall 25, and the bottom wall 25 and the side wall 23 may together enclose 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 throttling element 11, and the like are formed or installed in the accommodating space. In the illustrated embodiment, the housing 20 is generally rectangular, the bottom wall 25 is generally square, and the side wall 23 includes first, second, third, and

fourth side walls

232, 234, 236, 238 that are connected end-to-end. The first, second, third and

fourth sidewalls

232, 234, 236, 238 enclose a quadrilateral. The side where the first sidewall 232 is located may be regarded as a first side of the sidewall 23 or the housing 20, the side where the second sidewall 234 is located may be regarded as a second side of the sidewall 23 or the housing 20, the side where the third sidewall 236 is located may be regarded as a third side of the sidewall 23 or the housing 20, and the side where the fourth sidewall 238 is located may be regarded as a fourth side of the sidewall 23 or the housing 20. When installed in place, the side walls 23 or sides (first, second, third and fourth sides) of the housing 20 may respectively face four side walls of a room (e.g., a kitchen).

In other embodiments, the housing 20 may be other shapes, such as a hollow cylinder. When the housing 20 is cylindrical, the side wall 23 is circular and the bottom wall 25 is circular. And are not limited herein.

To illustrate, a portion of the side wall 23 of the housing 20 may be served by a side wall of a room.

The air conditioner 100 may be installed at a wall or a ceiling of a room 110, such as a kitchen. Most common rooms 110, including kitchens, typically include four side walls. The four-sided side wall typically has three

interior walls

1122, 1124, 1126 and one exterior wall 115. When installed, the four side walls of the housing 20 of the air conditioner 100 may each face a side wall of the room 110.

For example, the air conditioner 100 may be disposed between the ceiling 111 and a ceiling wall (not shown) of a kitchen. The upper ends of the side walls 23 may be adjacent or abut the lower surface of the kitchen ceiling wall and the lower surface of the bottom wall 25 may be adjacent or abut the upper surface of the ceiling 111. If necessary, a fixing member such as a screw may be provided between the housing 20 and the ceiling wall of the kitchen or the ceiling 111 to securely lock the three.

The ceiling 111 may be generally fabricated from a plurality of trim panels. The size (width by length) of an individual decorative panel may typically be 300mm (millimeters) by 300mm (millimeters), 300mm by 600mm, 600mm by 600mm, etc. The bottom wall 25 of the housing 20 of the first embodiment air conditioner 100 is rectangular in shape and has a length and width dimension of less than 600mm x 600mm and is configured to mate with one or more decorative panels C. The height of the housing 20 is less than the height of the ceiling to meet the installation requirements.

The housing 20 may also include a top wall 27, and the top wall 27 may substantially enclose the storage space. In other embodiments, the top wall may not be provided, as long as the airtightness of the respective main components inside the housing 20 can be ensured.

The air chamber 30 may be disposed at the third sidewall 236 and may include a first air chamber 33 and a second air chamber 35. The first and

second air chambers

33 and 35 may be separated by a partition to interrupt the air passage therebetween. Correspondingly, the third sidewall 236 may be opened with two

openings

13, 14. One of the openings 13 (which may be referred to as a first opening) communicates with the first air chamber 33 and serves as an inlet for room air outside the kitchen (e.g., air in a living room or hallway) to enter the first air chamber 33. The other opening 14 (which may be referred to as a second opening) may serve as an inlet for room air outside the kitchen (e.g., air in a living room or hallway) to enter the second air chamber 35. The indoor air is used as the air inlet of the air conditioner, so that the heat exchange efficiency of the air conditioner is improved.

In other embodiments, the opening 13 may be disposed on the second sidewall 234 as long as it can communicate with the first air chamber 33; the opening 14 may be provided in the fourth side wall 238 as long as it can communicate with the second air chamber 35.

The

openings

13, 14 may be circular holes, square holes, etc. When installed, the third side wall 236 with the

openings

13, 14 therein may be positioned opposite the interior wall 1122 of the room 110.

It will be readily appreciated that in other embodiments, the first and

second gas chambers

33, 35 may not be separated by a partition, and the first and

second gas chambers

33, 35 may be in gaseous communication. Correspondingly, only one

opening

13 or 14 may be provided.

A first air inlet conduit 131 and a second air inlet conduit 141 may be provided between the

openings

13, 14 and the interior wall 1122. A first end of the first air inlet pipe 131 is in air communication with other rooms through the inner wall 1122, and a second end of the first air inlet pipe 131 is hermetically connected to the opening 13, so that the room air outside the room 110 can enter the first air chamber 33 through the first air inlet pipe 131. To facilitate the connection of the first air inlet pipe 131 with the opening 13, a first connection member 133 may be provided at the opening 13. The first end of the first connecting member 133 has a shape matching the shape of the opening 13 (e.g., may be rectangular) and is connected to the opening 13 in an airtight manner; the second end of the first connection member 133 has a shape that matches the shape of the first air inlet pipe 131 (e.g., may be circular) and is hermetically connected to the first air inlet pipe 131. The middle portion of the first connecting member 133 is tapered to connect the first and second ends of the first connecting member 133.

A first end of the second air inlet pipe 141 is in air communication with other rooms through the inner wall 1122, and a second end of the second air inlet pipe 141 is hermetically connected to the opening 14, so that the indoor air outside the room 110 can enter the second air chamber 35 through the second air inlet pipe 141. To facilitate the connection of the second air inlet pipe 141 with the opening 14, a second connection 143 may be provided at the opening 14. The first end of the second connector 143 has a shape matching the shape of the opening 14 and is hermetically connected to the opening 14; the second end of the second connector 143 has a shape that matches the shape of the second air inlet pipe 141 and is air-tightly coupled to the second air inlet pipe 141. The middle portion of the second connecting member 143 is tapered to connect the first end and the second end of the second connecting member 143.

The first heat exchanger 60 and the first fan 70 may be disposed on a side of the first air chamber 33 away from the opening 13. The first heat exchanger 60 may have a passage through which a refrigerant (e.g., R113, R114, R115, R134a, R502, R22, etc.) flows. An air passage for air circulation is formed on the 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 may 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 may communicate with the first air chamber 33, so that air may freely circulate between the first air chamber 33 and the air passage at the first heat exchanger 60. In the cooling mode, the first heat exchanger 60 may operate as an evaporator.

The first heat exchanger 60 may be a multi-pass heat exchanger. For example, the heat exchanger can be a copper tube fin type heat exchanger, and can also be a micro-channel heat exchanger with flat tubes and collecting tubes. The micro-channel heat exchanger is beneficial to reducing the weight and the size of the air conditioner. The flat tube is usually provided with a plurality of channels for the flow of refrigerant therein. Adjacent channels are isolated from each other. A plurality of passageways are arranged in a row, influence the width of flat pipe jointly. The flat pipe is flat, and the length and the width of the flat pipe are respectively greater than the width and the thickness of the flat pipe. The length direction of the flat pipe is the flowing direction of the refrigerant determined by the channel in the flat pipe. The length direction of the flat pipe can be a straight line type, a broken line type, a bending type and the like. The flat tube described here is not limited to this type, and may be in other forms. For example, adjacent channels may not be completely isolated. As another example, all of the channels may be arranged in two rows, so long as the width is still greater than the thickness.

The first heat exchanger 60 may have a substantially plate shape having a length direction, a width direction, and a thickness direction. In the first embodiment, the longitudinal direction of the first heat exchanger 60 coincides with the line direction connecting the

openings

13 and 14, the width direction of the first heat exchanger 60 coincides with the height direction of the casing 20, and the thickness direction of the first heat exchanger 60 coincides with the direction from the third side wall 236 to the first side wall 232. The dimension of the first heat exchanger 60 in the thickness direction is smaller than the dimension of the first heat exchanger 60 in the length direction and the dimension in the width direction. The extending direction of the air passage through which the air can flow 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 generally in the thickness direction of the first heat exchanger 60.

The first fan 70 is used to provide a force for the air to flow from the first air chamber 33 to the first heat exchanger 60. The first fan 70 may employ a centrifugal fan. The first fan 70 may include a volute 72, and the impeller and the air inlet may be disposed at a center of the volute 72. The air path inside the volute 72 encircles the axis of rotation of the impeller. In the first embodiment, the first fan 70 is vertically disposed, and correspondingly, the rotation axis of the impeller is horizontally disposed. The air inlet of the first fan 70 faces the first heat exchanger 60, and the air outlet of the first fan 70 faces the second side wall 234. In other embodiments, the first fan 70 may be disposed horizontally, and correspondingly, the rotation axis of the impeller is disposed vertically.

After the first fan 70 is turned on, the outdoor air can continuously flow from the opening 13 to the first air chamber 33, and then flow from the first air chamber 33 to the air passage of the first heat exchanger 60. The air in the air passage can be cooled by the refrigerant in the first heat exchanger 60 to form cold air. After leaving the air passage of the first heat exchanger 60, the cool air may be sequentially sent to the kitchen through the first fan 70 and the air inlet 16. Wherein, the tuyere 16 can be an opening disposed on the second sidewall 234.

A blast pipe 161 may be provided at the tuyere 16. The blast duct 161 sends the cool air downward into the kitchen through the ceiling 111. To facilitate the connection of the air supply duct 161 to the tuyere 16, a connection member 163 may be provided at the tuyere 16. The first end of the connector 163 has a shape matching the shape of the tuyere 16 (e.g., may be rectangular) and is connected to the tuyere 16 in an airtight manner; the second end of the connector 163 has a shape that matches the shape of the air feeding tube 161 (e.g., may be circular) and is air-tightly coupled to the air feeding tube 161. The middle portion of the connecting member 163 is tapered to connect the first and second ends of the connecting member 163.

In other embodiments, the tuyere 16 may not be provided in the side wall 23 of the housing 20 but in the bottom wall 25 of the housing 20. Furthermore, the first heat exchanger 60 and the first fan 70 may be disposed in reverse positions. The first heat exchanger 60 may be disposed between the tuyere 16 and the first fan 70. The air introduced from the first air chamber 33 may be discharged into the room 110 through the first fan 70, the first heat exchanger 60, and the air outlet 16 in sequence.

A connection (not shown) may be provided between the first heat exchanger 60 and the first fan 70. The connector may be in the form of a half-or full-wrapped shell of tubing. A first end of the connector is positioned around the first heat exchanger 60 and a second end of the connector is positioned around the air intake of the first fan 70 so that air exiting the air path of the first heat exchanger 60 can completely enter the first fan 70.

Since the size of the first heat exchanger 60 is larger than the size of the inlet of the first fan 70, the size of the first end of the connector is larger than the size of the second end of the connector. The connector has a tendency to progressively narrow from the first end to the second end of the connector.

Of course, instead of providing the connection between the first heat exchanger 60 and the first fan 70, the partition 73 may be used to separate the gas environment of the first heat exchanger 60 and the first fan 70 from the gas environment of the second heat exchanger 80 and the second fan 90, so as to ensure that the cold and hot air is not mixed.

The vertically disposed first fan 70 occupies a small area and width on the bottom wall 25 of the housing 20 so that the compressor 50 can be disposed on the first heat exchanger 60, on the half of the housing 20 where the first fan 70 is located. At the half of the housing 20, the first heat exchanger 60, the first fan 70, and the compressor 50 may be arranged in sequence.

A drip pan (not shown) may be provided below the first heat exchanger 60. During the process of cooling the air in the air duct by the refrigerant in the first heat exchanger 60, condensed water may be formed and condensed on the surface of the first heat exchanger 60. The catch tray disposed below the first heat exchanger 60 can collect the condensed water well.

The second heat exchanger 80 and the second fan 90 may be disposed on a side of the second air chamber 35 away from the opening 14. The second heat exchanger 80 may be provided at the inside thereof with a passage through which a refrigerant flows. An air passage for air circulation is formed on the 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 may 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 may be in communication with the second plenum 35 such that air may freely circulate between the second plenum 35 and the air passage at the second heat exchanger 80. In the cooling mode, second heat exchanger 80 may operate as a condenser.

The second heat exchanger 80 may be a multi-pass heat exchanger. For example, the heat exchanger can be a copper tube fin type heat exchanger, and can also be a micro-channel heat exchanger with flat tubes and collecting tubes. The micro-channel heat exchanger is beneficial to reducing the weight and the size of the air conditioner. The flat tube is usually provided with a plurality of channels for the flow of refrigerant therein. Adjacent channels are isolated from each other. A plurality of passageways are arranged in a row, influence the width of flat pipe jointly. The flat pipe is flat, and the length and the width of the flat pipe are respectively greater than the width and the thickness of the flat pipe. The length direction of the flat pipe is the flowing direction of the refrigerant determined by the channel in the flat pipe. The length direction of the flat pipe can be a straight line type, a broken line type, a bending type and the like. The flat tube described here is not limited to this type, and may be in other forms. For example, adjacent channels may not be completely isolated. As another example, all of the channels may be arranged in two rows, so long as the width is still greater than the thickness.

The second heat exchanger 80 may be generally plate-shaped, having a length direction, a width direction, and a thickness direction. In the first embodiment, the length direction of the second heat exchanger 80 coincides with the line direction between the

openings

13 and 14, the width direction of the second heat exchanger 80 coincides with the height direction of the casing 20, and the thickness direction of the second heat exchanger 80 coincides with the direction from the third side wall 236 to the first side wall 232. The dimension of the second heat exchanger 80 in the thickness direction is smaller than the dimension of the second heat exchanger 80 in the length direction and the dimension in the width direction. The extending direction of the air passage through which the air can flow 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 in the thickness direction of the second heat exchanger 80.

The second fan 90 is used to provide a force for the air to flow from the second air chamber 35 to the second heat exchanger 80. The second fan 90 may employ a centrifugal fan. The second fan 90 may include a volute 92, and the impeller and the air inlet may be disposed at a center of the volute 92. The air path inside the volute 92 encircles the axis of rotation of the impeller. In the first embodiment, the second fan 90 is disposed horizontally, and correspondingly, the rotation shaft of the impeller is disposed vertically. The air inlet of the second fan 90 faces upward, and the air outlet of the second fan 90 faces the first sidewall 232. In other embodiments, the second fan 90 may be disposed vertically, and correspondingly, the rotation axis of the impeller is disposed horizontally.

After the second fan 90 is turned on, the outdoor air can continuously flow from the opening 13 to the second air chamber 35, and then flow from the second air chamber 35 to the air passage of the second heat exchanger 80. The air in the air passage can be heated by the refrigerant in the second heat exchanger 80 to form hot air. The hot air may be discharged to the outside through the second fan 90 and the opening 15 in this order after leaving the air passage of the second heat exchanger 80. Wherein, the opening 15 may be disposed on the first sidewall 232.

A hot blast duct 151 may be provided at the opening 15. The first end of the hot air duct 151 may be connected to the opening 15 in an airtight manner, and the second end of the hot air duct 151 may be connected to the outdoor environment, so that the hot air at the opening 15 may be discharged to the outdoor environment through the hot air duct 151. For example, the second end of the hot blast duct 151 may communicate with the outside environment through the flue 113. The flue 113 is a commonly installed duct for collecting oil smoke in the duct 114 of the range hood and discharging the oil smoke to the outside.

To facilitate the connection of the hot air duct 151 to the opening 15, a connection member 153 may be provided at the opening 15. The first end of the connecting member 153 has a shape matching the shape of the opening 15 (e.g., may be rectangular) and is connected to the opening 15 in an airtight manner; the second end of the connector 153 has a shape matching the shape of the hot air duct 151 (e.g., may be circular) and is connected to the hot air duct 151 in an airtight manner. The middle portion of the connection member 153 is tapered to connect the first end and the second end of the connection member 153.

In other embodiments, the second heat exchanger 80 and the second fan 90 may be reversed. The second heat exchanger 80 may be disposed between the opening 15 and the second fan 90. The air introduced from the second air chamber 35 may be discharged to the outside through the second fan 90, the second heat exchanger 80 and the opening 15 in this order.

A connection (not shown) may be provided between the second heat exchanger 80 and the second fan 90. The connector may be in the form of a half-or full-wrapped shell of tubing. The first end of the connector is positioned around the second heat exchanger 80 and the second end of the connector is positioned around the air inlet of the second blower 90 so that air exiting the air path of the second heat exchanger 80 can completely enter the second blower 90.

Since the size of the second heat exchanger 80 is larger than the size of the air inlet of the second blower 90, the size of the first end of the connector is larger than the size of the second end of the connector. The connector has a tendency to progressively narrow from the first end to the second end of the connector.

Of course, instead of providing the connection member between the second heat exchanger 80 and the second fan 90, the partition plate 73 may be used to separate the gas environment of the second heat exchanger 80 and the second fan 90 from the gas environment of the first heat exchanger 60 and the first fan 70, so as to ensure that the cold air and the hot air are not mixed.

The compressor 50 and the throttling element 11 may be connected to the passages of the first heat exchanger 60 and the passages of the second heat exchanger 80 through connection pipes T1, T2, T3, and T4 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 connection pipe T1, the second end of the compressor 50 may be connected to the first end of the second heat exchanger 80 through a connection pipe T2, the second end of the second heat exchanger 80 may be connected to the first end of the throttling element 11 through a connection pipe T3, and the second end of the throttling element 11 may be connected to the second end of the first heat exchanger 60 through a connection pipe T4.

In the cooling mode, the refrigerant is compressed by the compressor 50, and then delivered to the channel inside the second heat exchanger 80, and condensed to reduce the temperature. The cooled refrigerant is separated from the second heat exchanger 80 and then flows to the throttling element 11 and the passage inside the first heat exchanger 60 in sequence. The refrigerant in the first heat exchanger 60 can exchange heat with the air at the first heat exchanger 60, the air is cooled, and the refrigerant is heated. The heated refrigerant may then be returned to the compressor 50. Thus, a refrigerant cycle is formed.

The compressor 50 may employ a horizontal compressor having a relatively short height. The use of the horizontal type compressor is advantageous for reducing the height of the compressor 50, the housing 20, and the like. The throttling element 11 may be a capillary tube or a throttling valve (e.g., a thermostatic expansion valve) or the like.

Fig. 3 and 4 are schematic structural diagrams of an air conditioner 200 according to a second embodiment of the present application. The main difference from the air conditioner 100 is that the two

openings

13 and 14 in the air conditioner 200 are transposed.
