[0037] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0038] Reference below Figure 1-Figure 11 A window type air conditioner 100 according to an embodiment of the present invention is described.

[0039] exist Figure 1-Figure 11 , the height direction is the up-down direction in the figure, the width direction is the left-right direction in the figure, and the front-back direction is the front-back direction in the figure.

[0040] Combination Figure 1-Figure 3 As shown, the window air conditioner 100 includes: a refrigerant circuit, an outdoor unit, an indoor unit and a connecting bridge.

[0041] In the refrigerant circuit, the refrigerant circulates sequentially through the compressor 23, the condenser, the pressure reducer and the evaporator, one of the condenser and the evaporator is the outdoor heat exchanger 21, and the other is the indoor heat exchanger 31; and the outdoor unit is located on the outdoor side, and the outdoor unit includes a first housing 11 and an outdoor fan 22, a compressor 23 and an outdoor heat exchanger 21 arranged in the first housing 11. The pressure reducer can be an expansion valve or a capillary tube.

[0042] Specifically, an outdoor air passage is formed in the first housing 11, and an outdoor air inlet and an outdoor air outlet are formed in the first housing 11, that is, the outdoor air inlet and the outdoor air outlet are arranged on the surface of the first housing 11. The outdoor air outlet is located on the side of the first housing 11 facing the outdoors, so that outdoor air enters the first housing 11 from the outdoor air inlet, and then enters the outdoors from the outdoor air outlet.

[0043] The indoor unit is located indoors, and includes a second housing 12, an indoor fan 32 and an indoor heat exchanger 31 disposed in the second housing 12. An indoor air passage is formed in the second housing 12, and an indoor air inlet and an indoor air outlet are formed in the second housing 12, that is, the indoor air inlet and the indoor air outlet are disposed on the surface of the second housing 12. The indoor air outlet is located on a side of the second housing 12 facing the indoor room, so that the indoor air enters the second housing 12 from the indoor air inlet, and then enters the indoor room from the indoor air outlet.

[0044] It can be understood that the first housing 11 is arranged outdoors, that is, the first housing 11 is provided with an outdoor air inlet and an outdoor air outlet, and outdoor air enters the first housing 11 from the outdoor air inlet and then enters the outdoors from the outdoor air outlet. The outdoor air passage is arranged in the first housing 11, the compressor 23, the outdoor heat exchanger 21 and the outdoor fan 22 are all arranged in the first housing 11, and the outdoor air enters the first housing 11 from the outdoor air inlet, and is discharged outdoors from the outdoor air outlet after heat exchange in the first housing 11.

[0045] The second housing 12 is arranged indoors, and the first housing 11 and the second housing 12 are connected, that is, the second housing 12 is provided with an indoor air inlet and an indoor air outlet, and the indoor air enters the second housing 12 from the indoor air inlet and then enters the room from the indoor air outlet. The indoor heat exchanger 31 and the indoor fan 32 are located in the second housing 12, and the indoor air passage is also located in the second housing 12. The indoor air enters the second housing 12 and enters the room from the indoor air outlet after heat exchange at the indoor heat exchanger 31.

[0046] Since the first shell 11 is arranged outdoors and the second shell 12 is arranged indoors, the first shell 11 and the second shell 12 are spaced apart, and a window is provided between the first shell 11 and the second shell 12, and the second shell 12 is connected to the first shell 11 through the window.

[0047] The compressor 23 is arranged in the outdoor air passage. The compressor 23 is provided with an exhaust port and an air return port. The compressor 23 compresses the refrigerant so that the low-pressure refrigerant becomes a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor 23 from the air return port. After the compressor 23 compresses the low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor 23 from the air return port.

[0048] The outdoor heat exchanger 21 is disposed in the outdoor air passage to perform heat exchange between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger 21. The outdoor air entering the first housing 11 from the outdoor air inlet circulates in the outdoor air passage and exchanges heat with the refrigerant at the outdoor heat exchanger 21.

[0049] Outdoor air enters the first shell 11 from the outdoor air inlet, circulates in the outdoor air channel, and flows to the outdoor heat exchanger 21; the refrigerant circulates in the outdoor heat exchanger 21, and the outdoor air exchanges heat with the refrigerant when passing through the outdoor heat exchanger 21; the outdoor air after heat exchange flows through the outdoor air channel to the outdoor air outlet, and is discharged to the outside from the outdoor air outlet.

[0050] For example, the outdoor heat exchanger 21 works as a condenser in the cooling mode of the window air conditioner 100, so that the refrigerant compressed by the compressor 23 condenses by dissipating heat to the outdoor air through the outdoor heat exchanger 21. The outdoor heat exchanger 21 works as an evaporator in the heating mode of the window air conditioner 100, so that the decompressed refrigerant absorbs heat from the outdoor air through the outdoor heat exchanger 21 and evaporates.

[0051] When the window air conditioner 100 is cooling, the exhaust port of the compressor 23 is connected to the outdoor heat exchanger 21. The outdoor heat exchanger 21 is a condenser. The outdoor air entering from the outdoor air inlet flows to the outdoor heat exchanger 21, where the refrigerant releases a large amount of heat; the outdoor air absorbs the heat of the refrigerant.

[0052] When the window air conditioner 100 is heating, the exhaust port of the compressor 23 is connected to the indoor heat exchanger 31. The outdoor heat exchanger 21 is an evaporator. The refrigerant releases heat at the indoor heat exchanger 31 and then flows to the outdoor heat exchanger 21. The outdoor air entering from the outdoor air inlet flows to the outdoor heat exchanger 21, and the refrigerant absorbs heat from the outdoor air at the outdoor heat exchanger 21.

[0053] The outdoor fan 22 is disposed in the outdoor air passage. The outdoor fan 22 rotates to drive the outdoor air to enter the outdoor air passage from the outdoor air inlet, exchange heat with the outdoor heat exchanger 21, and then flow to the outdoors from the outdoor air outlet.

[0054] The outdoor fan 22 is located in the first shell 11. Driven by the outdoor fan 22, outdoor air enters the first shell 11 from the outdoor air inlet, flows through the outdoor air channel to the outdoor heat exchanger 21, and after the outdoor air exchanges heat with the refrigerant at the outdoor heat exchanger 21, the refrigerant is discharged to the outdoors from the outdoor air outlet under the drive of the outdoor fan 22.

[0055] Among them, the indoor fan 32 is a cross-flow fan, which can push or draw air along the fan axis direction, provide better air volume and air pressure, and bring a comfortable experience to the user.

[0056] Furthermore, the user can also adjust the air volume of the window air conditioner 100 by controlling the rotation speed of the indoor fan 32 to improve the user's comfort.

[0057] The indoor heat exchanger 31 is disposed in the indoor air passage to perform heat exchange between the indoor air and the refrigerant transmitted in the indoor heat exchanger 31. The indoor air entering the second housing 12 from the indoor air inlet circulates in the indoor air passage and exchanges heat with the refrigerant at the indoor heat exchanger 31.

[0058] Indoor air enters the second shell 12 from the indoor air inlet, circulates in the indoor air channel, and flows to the indoor heat exchanger 31; the refrigerant circulates in the indoor heat exchanger 31, and the indoor air exchanges heat with the refrigerant when passing through the indoor heat exchanger 31; the indoor air after heat exchange flows through the indoor air channel to the indoor air outlet, and is discharged into the room from the indoor air outlet.

[0059] For example, the indoor heat exchanger 31 operates as an evaporator in the cooling mode of the window air conditioner 100, so that the decompressed refrigerant absorbs the heat of the indoor air and evaporates through the indoor heat exchanger 31. The indoor heat exchanger 31 operates as a condenser in the heating mode of the window air conditioner 100, so that the refrigerant compressed by the compressor 23 condenses by dissipating the heat to the indoor air through the indoor heat exchanger 31.

[0060] When the window air conditioner 100 is cooling, the exhaust port of the compressor 23 is connected to the outdoor heat exchanger 21, and the indoor heat exchanger 31 is an evaporator. The refrigerant releases heat at the outdoor heat exchanger 21 and then flows to the indoor heat exchanger 31. The indoor air entering from the indoor air inlet flows to the indoor heat exchanger 31, and the refrigerant absorbs the heat of the indoor air at the indoor heat exchanger 31, thereby achieving the effect of cooling the room.

[0061] When the window air conditioner 100 is heating, the exhaust port of the compressor 23 is connected to the indoor heat exchanger 31. The indoor heat exchanger 31 is a condenser. The indoor air entering from the indoor air inlet flows to the indoor heat exchanger 31, and the refrigerant releases a large amount of heat at the indoor heat exchanger 31; the indoor air absorbs the heat of the refrigerant to achieve the effect of heating the room.

[0062] The indoor fan 32 is arranged in the second housing 12. The indoor fan 32 rotates to drive the airflow from the indoor air inlet into the indoor air passage and then flows from the indoor air outlet to the indoor room after exchanging heat with the indoor heat exchanger 31. The indoor fan 32 is located in the second housing 12. Driven by the indoor fan 32, the indoor air enters the second housing 12 from the indoor air inlet, flows through the indoor air passage to the indoor heat exchanger 31, and after the indoor air exchanges heat with the refrigerant at the indoor heat exchanger 31, the refrigerant is discharged from the indoor air outlet to the indoor room under the drive of the indoor fan 32.

[0063] In addition, the connecting bridge is at least partially located on the window, one end of the connecting bridge is connected to the indoor unit, and the other end is connected to the outdoor unit. That is to say, the indoor unit, the outdoor unit and the connecting bridge together form a reliable N-shaped structure, so that the window air conditioner 100 can be mounted on the window sill, which is more convenient to install than the traditional integrated square shape. Moreover, when the window air conditioner 100 is mounted on the window sill, the indoor unit and the outdoor unit located on the left and right sides of the window can keep the window air conditioner 100 balanced and stable, and the installation effect is more reliable.

[0064] like Figure 1As shown, the connecting bridge portion includes a connecting bridge housing 50, and the connecting bridge housing 50 is connected to the first housing 11 and the second housing 12 respectively, so as to realize that the connecting bridge portion connects the outdoor unit portion and the indoor unit portion. That is, the first housing 11 and the second housing 12 are connected through the connecting bridge housing 50, the side of the first housing 11 facing indoors abuts against the connecting bridge housing 50, and the side of the first housing 11 facing indoors is connected to one end of the connecting bridge housing 50; the side of the second housing 12 facing outdoor abuts against the connecting bridge housing 50, and the side of the second housing 12 facing outdoor is connected to the other end of the connecting bridge housing 50.

[0065] according to Figure 4 , Figure 6 and Figure 7 As shown, the window air conditioner 100 also includes: a first sliding assembly, the first sliding assembly is clamped between the connecting bridge housing 50 and the second housing 12, the first sliding assembly includes: a first sliding member 13 and a second sliding member 53, the first sliding member 13 is fixed on the second housing 12, the second sliding member 53 is fixed on the connecting bridge housing 50, the first sliding member 13 and the second sliding member 53 slide with each other to drive the second housing 12 to move in the height direction relative to the connecting bridge housing 50.

[0066] It can be understood that the second housing 12 and the connecting bridge housing 50 are connected by the first sliding assembly, and the second housing 12 can slide in the height direction relative to the connecting bridge housing 50. The user can adjust the second housing 12 to raise and lower the indoor unit, and the indoor air outlet height of the indoor unit can be increased, thereby improving the user experience.

[0067] Further, the second housing 12 is provided with a first sliding member 13, the connecting bridge housing 50 is provided with a second sliding member 53, and the second sliding member 53 is fixedly connected to the connecting bridge housing 50. The first sliding member 13 and the second sliding member 53 are slidably connected, and the first sliding member 13 can slide relative to the second sliding member 53 in the height direction. The first sliding member 13 is fixedly connected to the second housing 12, so that the second housing 12 can move relative to the connecting bridge housing 50 in the height direction, thereby raising the height of the indoor air outlet and improving the air outlet height of the window air conditioner 100.

[0068] Reference Fig.11 As shown, in the height direction of the window air conditioner 100, the second housing 12 can move upward relative to the connecting bridge housing 50, so that the window has a better visual effect and the height of the indoor air outlet can be increased, thereby providing users with a better air supply experience. In addition, the second housing 12 is made of plastic material. Compared with the sheet metal material of traditional models, the plastic material of the same volume is lighter, and the user can operate the window air conditioner 100 more easily. In addition, the manufacturing process of the plastic parts is relatively simple, and the second housing 121 is made of beautiful appearance, which can also greatly improve the production efficiency.

[0069] Therefore, a first sliding member 13 is provided on the second outer shell 12, and a second sliding member 53 is provided on the connecting bridge shell 50. The first sliding member 13 and the second sliding member 53 are slidably connected, so that the second outer shell 12 can move in the height direction relative to the connecting bridge shell 50. The user can raise and lower the second outer shell 12, thereby adjusting the height of the air outlet of the indoor unit, so that the air supply experience is more in line with human comfort requirements.

The first sliding member 13 is arranged on the back plate 122, and the second sliding plate is fixed on the hanging plate 54, so the hanging plate 54 and the back plate 122 are slidably connected, and the back plate 122 and the hanging plate 54 slide with each other. The height of the hanging plate 54 does not change in the height direction, and the back plate 122 can slide along the height direction. The hanging plate 54 is fixedly connected to the first plate 55, and the back plate 122 and the second bridge section 51 are slidably connected, so that the second housing 12 can move relative to the connecting bridge shell 50 in the height direction to achieve the height adjustment of the indoor air outlet and improve the air supply experience.

[0081] In some embodiments, there are two first sliding assemblies, which are respectively disposed on both sides of the back plate 122 and the hanging plate 54 in the left and right directions. The two first sliding assemblies are respectively located on both sides of the left and right directions of the window air conditioner 100, so that when the second housing 12 moves in the height direction, the process of the second housing 12 moving in the height direction is ensured to be smoother and the operation is smoother.

[0082] like Figure 2 , Figure 3 and Fig.10 As shown, the refrigerant circuit further includes: a refrigerant pipeline 40 , and the refrigerant pipeline 40 is connected between the compressor 23 and the indoor heat exchanger 31 .

[0083] During cooling, the refrigerant pipeline 40 connects the compressor 23, the outdoor heat exchanger 21 and the indoor heat exchanger 31. After the refrigerant is discharged from the exhaust port of the compressor 23, the refrigerant passes through the outdoor heat exchanger 21 and releases heat in the outdoor heat exchanger 21; the refrigerant after releasing heat is decompressed by the pressure reducer and flows to the indoor heat exchanger 31 through the refrigerant loop. The refrigerant absorbs the heat of the indoor air at the indoor heat exchanger 31, and the indoor air after heat exchange flows to the room, realizing indoor cooling.

[0084] During heating, the refrigerant pipeline 40 connects the compressor 23 and the indoor heat exchanger 31. After the refrigerant is discharged from the exhaust port of the compressor 23, the refrigerant flows into the refrigerant pipeline 40, enters the second shell 12 from the first shell 11, flows through the indoor air channel to the outdoor heat exchanger 21, and releases heat at the outdoor heat exchanger 21 to achieve heating. The refrigerant after heat release is reduced in pressure by the pressure reducer, and flows to the outdoor heat exchanger 21 through the refrigerant loop. The refrigerant absorbs heat from the outdoor air at the outdoor heat exchanger 21, and the refrigerant after heat absorption returns to the compressor 23 from the return air port.

[0085] according to Figure 4 , Figure 7 and Fig. 9 As shown, an open slot 14 is provided on the back plate 122, and the open slot 14 extends in the height direction. When the second shell 12 moves in the height direction, the refrigerant pipeline 40 moves up and down in the open slot 14. Part of the refrigerant pipeline 40 is located in the second shell 12, and another part of the refrigerant pipeline 40 is located between the connecting bridge housing 50 and the second shell 12, that is, the connection between the refrigerant pipeline 40 and the second pipeline 42 is located between the connecting bridge housing 50 and the second shell 12, and this part of the refrigerant pipeline 40 passes through the open slot 14 on the back plate 122 to extend between the connecting bridge housing 50 and the second shell 12.

[0086] The opening groove 14 extends in the height direction. When the second shell 12 moves upward in the height direction relative to the connecting bridge shell 50 , the refrigerant pipeline 40 stretches and moves in the opening groove 14 to adapt to the up and down movement of the second shell 12 .

[0087] The depth of the opening groove 14 is slightly smaller than the height of the back plate 122. When the second outer shell 12 moves upward to the extreme position (the maximum upward displacement of the second outer shell 12) relative to the connecting bridge shell 50 in the height direction, one end of the first pipeline 41 connected to the second pipeline 42 abuts against the bottom of the opening groove 14, and the opening groove 14 serves as a limit for the first pipeline 41.

[0088] In some embodiments, the first sliding member 13 is one of a slide rail and a slide groove, and the second sliding member 53 is the other of the slide rail and the slide groove, and the slide rail and the slide groove are slidably matched.

[0089] If the first sliding member 13 is a slide groove, the second sliding member 53 is a slide rail, the slide rail and the slide groove extend in the height direction, the slide rail and the slide groove are slidably connected, the slide groove is fixed on the back plate 122, the slide rail is fixed on the hanging plate 54, the back plate 122 and the hanging plate 54 are slidably connected, so that the second shell 12 can slide in the height direction relative to the connecting bridge shell 50, thereby adjusting the height of the indoor air outlet.

[0090] In some embodiments, the first sliding member 13 is one of a sliding sleeve and a sliding column, and the second sliding member 53 is the other of the sliding sleeve and the sliding column, and the sliding sleeve and the sliding column are slidably matched. If the first sliding member 13 is a sliding sleeve, and the second sliding member 53 is a sliding column, the sliding column and the sliding sleeve are slidably matched, and the sliding sleeve and the sliding column extend in the height direction, the sliding sleeve is arranged on the back plate 122, and the sliding column is arranged on the hanging plate 54, and the back plate 122 can move in the height direction relative to the hanging plate 54, so that the second housing 12 can slide in the height direction relative to the connecting bridge housing 50, thereby adjusting the height of the indoor air outlet.

[0091] If the first sliding member 13 is a sliding column and the second sliding member 53 is a sliding sleeve, the sliding column and the sliding sleeve are slidably matched, the sliding sleeve and the sliding column extend in the height direction, the sliding column is arranged on the back plate 122, and the sliding sleeve is arranged on the hanging plate 54, and the back plate 122 can move in the height direction relative to the hanging plate 54, so that the second outer shell 12 can slide in the height direction relative to the connecting bridge shell 50, thereby adjusting the height of the indoor air outlet.
