The wall-mounted air conditioner indoor unit 100 of the present embodiment may generally include: casing 110, air supply assembly, heat exchanger 121.
The casing 110 has a heat exchange air-supplying chamber defined therein. The side of the casing 110 facing the user is a front panel 111, and a casing 112 is provided at the rear of the front panel 111, and the casing 112 and the front panel 111 cooperate to define a heat exchange blowing chamber. The casing 112 may be formed of a top wall, side walls, a back, and a bottom wall, and the front panel 111 is disposed in front of the casing 112 to close the heat exchanging blast chamber.
The casing 110 is provided with an air inlet 113, a first air supply outlet 114, and a second air supply outlet 115, wherein the first air supply outlet 114 and the second air supply outlet 115 are arranged in different directions. For example, the first supply outlet 114 may face the front of the cabinet 110, and the second supply outlet 115 may face the lower side of the cabinet 110. In some embodiments, the first blowing port 114 may be provided on the front panel 111, and the second blowing port 115 is provided on the bottom of the casing 110, that is, on the bottom wall of the casing 112.
The air supply assembly is arranged in the heat exchange air supply cavity and comprises an air supply part 210 and an air guide part 310, and a fan 211 used for promoting the flow of heat exchange air flow is arranged in the air supply part 210.

The heat exchanger 121 is a part of a refrigeration system, and the refrigeration system may be implemented by using a compression refrigeration cycle, which uses a compression phase change cycle of a refrigerant in a compressor, a condenser, an evaporator, and a throttling device to implement heat transfer. The refrigeration system may further include a four-way valve to change the flow direction of the refrigerant, so that the heat exchanger 121 may be alternately used as an evaporator or a condenser to perform a cooling or heating function. Since the compression refrigeration cycle in the air conditioner is well known to those skilled in the art, the operation principle and structure thereof will not be described herein. The heat exchanger 121 may be plate-type and is disposed against the front plate 111.
The heat exchange air supply cavity can be also internally provided with a partition plate 122 and other components for fixing the heat exchanger 121 and other components, and can also seal air flow to avoid air leakage.
Fig. 4 is a schematic view illustrating the air supply part 210 and the air guide part 310 of the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention.
The air supply part 210 and the air guide part 310 are arranged along the length direction of the casing 110, so that the air supply assembly is transversely arranged in the heat exchange air supply cavity. As will be appreciated by those skilled in the art, the length of the housing 110 of the wall-mounted air conditioner indoor unit 100 is significantly greater than the height and the depth distance in the front-back direction, and thus the transverse direction is the length direction of the housing 110 in this embodiment. The air inlet 113 is disposed in a region of the front panel 111 of the casing 110 corresponding to the fan 211 (e.g., a region of the front panel 111 of the casing 110 corresponding to the fan 211), the air inlet 113 may further be provided with an air inlet grille, in order to maintain the overall appearance of the indoor unit 100, the first air outlet 114 is disposed in a region of the front panel 111 of the casing 110 corresponding to the air guiding portion 310, and the second air outlet 115 is disposed in a region of the bottom wall of the casing 110 corresponding to the air guiding portion 310. As shown in the drawings, the air supply part 210 is located in the left half of the indoor unit 100, the air guide part 310 is located in the right half of the indoor unit 100, and after entering the indoor unit 100 from the left half, the airflow is guided in the heat exchange air supply cavity through heat exchange and then sent back to the indoor environment from the right half. Of course, those skilled in the art can easily understand the corresponding structure of the air supply part 210 located on the right half part of the indoor unit 100 and the air guide part 310 located on the left half part of the indoor unit 100 according to the disclosure of the present embodiment. Therefore, the wall-mounted air conditioner indoor unit of the embodiment can be respectively suitable for different installation positions.
In this embodiment, the fan 211 of the indoor unit 100 may selectively use a fan that supplies air in the axial direction and discharges air in the circumferential direction, for example, a centrifugal fan. The fan 211 rotation axis is disposed along the front-rear direction of the cabinet 110. The air inlet 113 is provided in a region of the front panel 111 of the casing 110 corresponding to the axial direction of the centrifugal fan 211 (e.g., a region of the front panel 111 of the casing 110 corresponding to the axial direction of the centrifugal fan 211). The heat exchanger 121 is interposed between the front panel 111 of the casing 110 and the air intake side of the centrifugal fan 211.
The air supply portion 210 further includes a blower volute 212 disposed at an outer periphery of the centrifugal blower 211. Air outlet 214 of fan volute 212 extends toward the side of air guide 310, e.g., from the bottom of fan volute 212 toward air guide 310. When the impeller of the centrifugal fan 211 is driven by the high-speed motor 213 to rotate along with the shaft, the gas between the impellers rotates along with the impeller to obtain centrifugal force, the gas is thrown out of the impeller and enters the fan volute 212, and the pressure of the gas in the fan volute 212 is increased and guided to be discharged. After the gas between the blades is exhausted, negative pressure is formed. Air is continuously sucked in through the air inlet 113 by exchanging heat through the heat exchanger 121, so that a continuous air flow is formed.
The air guide portion 310 may include an air guide scroll 301, a first air blowing member 330, and a second air blowing member 320. The air guide volute 301 is used for guiding the air exchange flow, and the first air supply member 330 is used for supplying air to the first air supply outlet 114; the second blowing member 320 blows air to the second blowing port 115.
The air guide volute 301 is connected to the air outlet 214 of the air supply portion 210, an annular air duct is defined therein, an air guide duct 304 penetrating through the air guide volute is formed at the center, and the air guide duct 304 is opposite to the first air supply outlet 114. The outer wall of the annular air duct is opened towards one side of the air outlet 214 of the air supply part 210 so as to be connected with the air outlet 214 of the air supply part 210; the inner wall of the annular duct may form an opening for blowing air to the first blowing member 330.
The first air blowing member 330 is disposed in the induced air duct 304 and is communicated with the annular air duct. The first air supply member 330 includes a plurality of concentrically arranged jet air rings 331, and jet ports are formed between the jet air rings 331, and the jet ports are configured to eject air flow of the annular air duct forward and drive air in the induced air duct 304 to be sent out forward.
The outer circumference of the first blowing member 330 is adapted to the inner shape of the annular air duct, for example, the first blowing member is circular. The outer circumference of the first blowing member 330 receives the air flow sent out from the inner wall of the annular air duct. The plurality of jet flow vanes 331 of the first air blowing member 330 may have horn shapes with different sizes, and a gap formed between adjacent jet flow vanes 331 forms a jet opening. The jet port forms a continuous outward-expanding coanda surface by means of the outward-expanding peripheral surface of the front jet air ring 331, and the acceleration of the airflow through the jet port can drive the ambient air in the central air induction duct 304 of the first air supply member 330. The ambient air is mixed with the heat exchange air flow ejected from the jet opening, so that on one hand, the wind power is increased, and the air flow can be sent out for a longer distance; on the other hand, the air flow sent out can be softer, and the user feels more comfortable.
In order to improve the jet velocity of the jet orifice, the width of the jet orifice can be configured according to the test result, for example, the width is set to be 1-3 mm, through a large amount of tests, the width of the jet orifice can be preferably set to be about 2mm, the jet velocity of the heat exchange airflow is ensured by the jet orifice with the size width, the windage loss of the heat exchange airflow can be reduced as much as possible, and the noise is reduced.
In order to match with the induced air duct 304, an induced air port 119 is formed at a position of the rear wall of the casing 110 opposite to the induced air duct 304; the area of the rear wall of the casing 110 opposite to the first blowing member 330 is recessed forward so that the rear of the induced air port 119 has an air circulation area 305. The draft air duct 304 communicates with the air circulation area 305, and the heat exchange gas ejected from the jet ports can draw the ambient air from the air circulation area 305.
A first air door 116 is arranged at the first air supply outlet 114, and a second air door 117 is arranged at the induced air outlet 119, and the first air door 116 and the second air door 117 are respectively configured to be controlled to open and close, so that the jet outlet and/or the induced air duct 304 are correspondingly opened and closed. For example, when both first damper 116 and second damper 117 are closed, both the jet opening and the induced draft duct 304 are closed. When the first damper 116 is opened and the second damper 117 is closed, the jet port is opened and the induced air duct 304 is closed. At this point only the heat exchange air stream is sent out and the ambient air cannot be drawn in. The first air door 116 and the second air door 117 are both opened, the jet opening and the induced air duct 304 are both opened, and the ambient air is driven by the heat exchange airflow and is sent out after being mixed.
Under the condition that the air outlet 214 of the fan volute 212 extends from the bottom of the fan volute 212 towards the air guiding portion 310, heat exchange airflow is diffused and sent out through the air outlet 214, the airflow speed near the bottom portion is higher, namely, upper-layer low-speed airflow and lower-layer high-speed airflow are formed and flow into the jet flow port, the airflow is accelerated by the jet flow air ring 331, strong negative pressure is formed at the jet flow port due to the wall effect, a large amount of ambient air in the air guiding duct 304 is sucked, the temperature of the air outlet is raised after mixed flow with the heat exchange airflow, and the body feeling is more comfortable. Along with the mixed flow air flow with higher lower layer speed and lower upper layer speed, the higher speed high pressure air flow sent out from the lower part of the first air supply outlet 114 lifts the lower speed low pressure air flow at the upper part and sends out the mixed flow air flow forwards, and the problems that the low speed air flow is high in lift attenuation, the wind direction is inclined downwards and the like are directly blown to people can be solved. Therefore, the air outlet 214 of the fan volute 212 extends from the bottom of the fan volute 212 to the air guide portion 310, so that the air flow sent by the first air supply outlet 114 can be further supplied, the temperature is softer, and the body feeling is more comfortable.
A bypass port 302 for supplying air to the second air supply port 115 is further formed in one side of the air guide volute 301, which is far away from the air supply portion 210, and a third air door 303 is arranged at the bypass port 302. The third damper 303 is configured to be controlled to open and close so that the second blowing port 115 opens or stops blowing air.
And a second blowing member 320 defining an air passage from the bypass outlet 302 to the second blowing outlet 115. An alternative configuration of the second blowing member 320 includes: a reversing section 321, an expanding section 322 and an air supply section 323.
And a direction-changing section 321 connected to the bypass port 302 and bent to extend downward to guide a direction of the air flow discharged from the bypass port 302 downward to a direction along a length of the casing 110. That is, the turning section 321 extends as the air guide scroll 301 to change the direction of the supply air flow.
And the diameter expanding section 322 is connected with the tail end of the reversing section 321, and the radial size of the air flue of the diameter expanding section 322 is larger than that of the air flue of the reversing section 321. The diameter-expanding section 322 converts the dynamic pressure of the air flow into the static pressure by the gradually expanding sectional area, so that the air outlet of the second air outlet 115 is more stable.
And an air supply section 323 arranged in the heat exchange air supply cavity and connected with the tail end of the diameter expansion section 322, and the bottom of the air supply section 323 is provided with an air outlet opposite to the second air supply outlet 115. The blowing section 323 extends along the bottom wall of the casing 112 by a certain length. The air outlets of the second air supply outlet 115 and the air supply section 323 are both strip-shaped extending along the length direction of the casing 110, and an air deflector 118 is further disposed at the second air supply outlet 115. The air deflector 118 can adjust the blowing direction of the second blowing port 115 within a certain angle. The second air supply outlet 115 is generally used for supplying air downward, and is mainly used in a heating mode of the indoor unit 100 to supply air to the feet of a user, so that the problem of head heat and foot cold can be avoided.
In the wall-mounted air conditioner indoor unit 100 of the present embodiment, two air supply outlets having different air supply directions are formed in the casing 110, and one or two of the two air supply outlets are selected by the air guide portion 310 to supply air. Depending on the heating or cooling mode, the air blowing requirements in different modes are satisfied by opening and closing first damper 116, second damper 117, and third damper 303.
Fig. 5 is a flow chart illustrating an air flow in a cooling mode in the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention. The arrows in the figure are the air flow directions. When the wall-mounted air conditioner indoor unit 100 performs cooling, the first damper 116 and the second damper 117 are opened, the third damper 303 is closed, and the first air supply outlet 114 supplies air to the outside. The airflow enters the heat exchange air supply cavity from the air inlet 113 and exchanges heat with the heat exchanger 121 behind the front panel 111. The air enters the fan volute 212 after being pressurized and accelerated by the fan 211, and is conveyed into the air guide volute 301 from the air outlet 214 through the rectification of the fan volute 212. Because the air outlet 214 of the fan volute 212 is attached to the bottom of the fan volute 212, the lower part of the air guide volute 301 has higher air speed and larger air pressure; since the bypass port 302 is closed, the heat exchange air flow is sent forward from the jet port of the first blowing member 330. Under the acceleration of the jet air ring 331, the air flow enables the jet outlet to form strong negative pressure by the wall effect, a large amount of environment in the induced air duct 304 is introduced and sucked, the temperature of the air outlet is raised after the air flow is mixed with the heat exchange air flow, and the body feeling is more comfortable. Along with the mixed flow air flow with higher speed at the lower layer and lower speed at the upper layer, the higher-speed high-pressure air flow sent out from the lower part of the first air supply outlet 114 lifts the air flow pressed by the lower speed at the upper part and is sent out forwards, and the problems that the low-speed air flow is fast in lift attenuation, the wind direction is inclined downwards and the like are directly blown to people can be solved.
When the wall-mounted air conditioner indoor unit 100 is used for heating, different air supply modes can be selected according to requirements. In the first heating heat exchange mode, both the first damper 116 and the second damper 117 are closed, and the third damper 303 is opened to supply air only from the second air supply outlet 115. The airflow enters the heat exchange air supply cavity from the air inlet 113 and exchanges heat with the heat exchanger 121 behind the front panel 111. The air enters the fan volute 212 after being pressurized and accelerated by the fan 211, and is conveyed into the air guide volute 301 from the air outlet 214 through the rectification of the fan volute 212. Since the first damper 116 and the second damper 117 are both closed, the outlet of the first blowing member 330 is closed, all the airflow enters the second blowing member 320 from the bypass port 302 and is blown out downward from the second blowing port 115, and the airflow direction can be adjusted to a certain extent by the air deflector 118 of the second blowing port 115. The air flow is sent out downwards, and the leg and foot positions of the user can be quickly heated.
In the second heating and heat exchanging mode, the first damper 116 is opened, the second damper 117 is closed, the third damper 303 is opened, and the first supply port 114 and the second supply port 115 supply air simultaneously. The airflow enters the heat exchange air supply cavity from the air inlet 113 and exchanges heat with the heat exchanger 121 behind the front panel 111. The air enters the fan volute 212 after being pressurized and accelerated by the fan 211, and is conveyed into the air guide volute 301 from the air outlet 214 through the rectification of the fan volute 212. A part of the air flow is sent out from the jet opening of the first air supply member 330 forward, and the air flow sent out from the first air supply opening 114 is not mixed with the ambient air flow due to the closing of the second damper 117; the other part of the air flow is sent out from the second air supply member 320 to heat the bottom of the room, thereby meeting the requirement of heating the whole room.
In the wall-mounted air conditioner indoor unit 100 of the present embodiment, two air supply outlets with different air supply directions are formed in the casing 110, and one or two of the two air supply outlets are selected to supply air through the air guide part 310, so that the selection of the air supply direction is expanded, and the first air supply outlet 114 is disposed on the front panel 111 of the casing 110, is used for supplying air to the front part of the indoor unit 100, and is suitable for supplying air forwards with a large air volume during cooling or heating; the second air supply outlet 115 is disposed at the bottom of the casing 110, and is suitable for supplying air to the feet of the user during heating. The air supply outlet structure can be used for realizing an air supply mode corresponding to a heat exchange mode. In addition, the first air supply outlet 114 can supply air by adopting a jet port mode, and sucks ambient air to mix with heat exchange airflow with severe temperature difference of the ambient environment, so that the delivered airflow is soft and comfortable to blow to a human body, on one hand, the air supply amount is increased, the flow of indoor air is accelerated,
