Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular to an air conditioner that can be installed on a ceiling. Background Art

[0002] The indoor unit of a common small household air conditioner is usually installed on the side of the room wall, which more or less destroys the overall aesthetics of the room decoration. In order to pursue beauty, many families will choose to install hidden duct units. In related technologies, duct units are usually installed above 2.5 meters, and generally adopt the form of front air supply and lower air return. Due to its high installation height, the air volume and wind speed sent downward are seriously attenuated, making it difficult for the hot air sent to the ground, resulting in poor comfort. At the same time, the hidden type is also inconvenient for maintenance. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an air conditioner, which can blow air to the ground when heating when the air conditioner is installed at a height greater than 2.5m, thereby facilitating improving the thermal comfort of the room.

[0004] According to an air conditioner of an embodiment of the present invention, the air conditioner has a cooling mode and a heating mode, and the air conditioner comprises: a shell, the shell is provided with an air inlet and the front wall of the shell is provided with an air outlet; a volute, the volute comprises a volute body and a volute tongue, the volute tongue is connected to the lower surface of the outlet end of the volute body, and an air guide duct is defined in the volute; a wind wheel, the wind wheel is arranged in the air guide duct; an indoor heat exchanger, the indoor heat exchanger is arranged in the shell and is located between the air inlet and the inlet end of the volute; an outlet air guide section, the outlet air guide section is arranged on the shell, the outlet air guide section is arranged on the front side of the volute tongue and extends downwardly, the volute is rotatable around the central axis of the wind wheel, and in the cooling mode the volute tongue cooperates with the upper end of the outlet air guide section; in the heating mode, the volute rotates to be separated from the outlet air guide section, the outlet end of the volute faces downward, and the outlet air guide section is located in the air guide duct.

[0005] According to the air conditioner of the embodiment of the present invention, the volute tongue is connected to the lower surface of the volute body, and the volute can rotate around the central axis of the wind wheel. In the cooling mode, the volute tongue cooperates with the upper end of the outlet air guide section, and in the heating mode, the volute can be rotated to separate from the outlet air guide section and the outlet end of the volute faces downward. Therefore, the user can adjust the rotation angle of the volute relative to the wind wheel to adjust the air supply angle of the air conditioner according to personal needs. In particular, when the air conditioner is in the heating mode, the outlet end of the volute is directed downward and the hot air discharged through the outlet end of the volute under the action of the volute tongue is more inclined to be supplied directly downward. At this time, the outlet air guide section has a smaller angle with the default air outlet direction of the air guide duct, which reduces the air volume loss caused by the outlet air guide section, and ensures that the heating air supply has a larger air volume and a favorable wind direction at the same speed of the wind wheel, which is conducive to the hot air being blown to the ground, and then it is conducive to improving the thermal comfort of the indoor environment.

[0006] In some embodiments of the present invention, a stop protrusion is provided on the bottom wall of the shell, and in the heating mode, the volute tongue contacts the stop protrusion.

[0007] Specifically, in the heating mode, the volute tongue is located at the front side of the stop protrusion.

[0008] In some embodiments of the present invention, a limiting protrusion is provided on the top wall of the shell, and in the cooling mode, the outer peripheral wall of the volute contacts the limiting protrusion.

[0009] In some embodiments of the present invention, the air conditioner further comprises an air guide assembly rotatably disposed at an outlet end of the air guide duct, and the rotation of the volute drives the rotation of the air guide assembly.

[0010] In some embodiments of the present invention, the wind wheel is a centrifugal wind wheel.

[0011] In some embodiments of the present invention, the air inlet is arranged on the bottom wall of the shell.

[0012] In some embodiments of the present invention, the outlet air guide section is rotatably disposed on the shell.

[0031] Reference below Figure 1-Figure 3 The air conditioner 100 according to the embodiment of the present invention is described, and the air conditioner 100 can be used to adjust the temperature of the indoor environment. In particular, the air conditioner 100 according to the present invention can be semi-hidden and exposed on the top of the room, which is beautiful in appearance and convenient for maintenance, while ensuring thermal comfort when the installation height is increased.

[0032] like Figure 1-Figure 3 As shown, according to an embodiment of the air conditioner 100 of the present invention, the air conditioner 100 has a cooling mode and a heating mode. The air conditioner 100 may include a shell 1, a volute 2, a wind wheel 3, an indoor heat exchanger 4 and an outlet air guide section 5, and the volute 2 and the wind wheel 3 are both installed in the shell 1.

[0033] refer to Figure 1-Figure 3 As shown, the housing 1 is provided with an air inlet 11 and the front wall of the housing 1 is provided with an air outlet 12. Figure 1 As shown, a mounting cavity 15 is formed in the housing 1, an air inlet 11 communicating with the mounting cavity 15 is provided on the housing 1, and an air outlet 12 communicating with the mounting cavity 15 is provided on the front wall of the housing 1. Indoor air can enter the housing 1 through the air inlet 11 and can be discharged through the air outlet 12.

[0034] refer to Figure 1-Figure 3 As shown, the volute 2 includes a volute body 21 and a volute tongue 22, the volute tongue 22 is connected to the lower surface of the outlet end 211 of the volute body 21, an air guide duct 23 is defined in the volute 2, and the wind wheel 3 is arranged in the air guide duct 23. It should be noted that the wind wheel 3 is connected to a motor (not shown in the figure), and the motor can drive the wind wheel 3 to rotate, and the volute 2 has an inlet end 212. For example, the inlet ends 212 are provided on both sides of the axial direction of the volute 2, the air guide duct 23 is defined in the volute 2, the wind wheel 3 is arranged in the air guide duct 23 and the wind wheel 3 is connected to the motor shaft of the motor, when the motor drives the wind wheel 3 to operate, the airflow in the installation cavity 15 can enter the volute 2 from the inlet end 212 of the volute 2 and be discharged from the volute 2 through the air guide duct 23.

[0035] refer to Figure 1-Figure 3As shown, at least a part of the indoor heat exchanger 4 is disposed in the housing 1 and is located between the air inlet 11 and the inlet end 212 of the volute 2. When the air conditioner 100 is working, under the driving action of the wind wheel 3, the air entering the housing 1 through the air inlet 11 can exchange heat with the part of the indoor heat exchanger 4 located in the housing 1, and then enter the volute 2 through the inlet end 212 of the volute 2, and then be discharged to the outlet 12 through the outlet end 211 of the volute 2 to adjust the temperature of the indoor space.

[0036] Reference Figure 1-Figure 3 As shown, the outlet air guide section 5 is provided on the housing 1, and the outlet air guide section 5 is provided on the front side of the volute tongue 22 and extends downwardly obliquely. Thus, the air discharged through the outlet end 211 of the volute 2 can be sent obliquely downward, which is conducive to the air discharged from the air outlet 12 of the air conditioner 100 being blown obliquely downward to the ground.

[0037] Reference Figure 2 and Figure 3 As shown, the volute 2 can rotate around the central axis of the wind wheel 3, and in the cooling mode, the volute tongue 22 cooperates with the upper end of the outlet air guide section 5; in the heating mode, the volute 2 rotates to separate from the outlet air guide section 5, and the outlet end 211 of the volute 2 faces downward, and the outlet air guide section 5 is located in the air guide duct 23. For example, the air conditioner 100 further includes a drive motor, which is arranged in the installation cavity 15 and the motor shaft of the drive motor is connected to the volute 2, and the central axis of the motor shaft and the central axis of the wind wheel 3 are on the same straight line, and the drive motor can drive the volute 2 to rotate around the central axis of the wind wheel 3. Therefore, in the cooling mode, the volute tongue 22 is connected with the upper end of the outlet air guide section 5 so that the cold air in the air guide duct 23 is blown out in a horizontal direction, thereby realizing the circulation of cold air from top to bottom in the indoor environment, which is beneficial to improving the user experience; in the heating mode, the volute 2 is rotated to separate from the outlet air guide section 5 and the outlet end 211 of the volute 2 is downward, so that the hot air in the air guide duct 23 can be blown out downward. At this time, the outlet air guide section 5 has a smaller angle with respect to the default air outlet direction of the air guide duct 23, reducing the air volume loss caused by the outlet air guide section 5, and ensuring that the heating air supply has a larger air volume and a favorable wind direction at the same rotation speed of the wind wheel 3, which is beneficial to the hot air blowing to the ground, and then the hot air can circulate from bottom to top in the indoor environment, which is beneficial to improving the thermal comfort of the indoor environment.

[0038] In an embodiment of the present invention, the user can adjust the rotation angle of the volute 2 relative to the wind wheel 3 to adjust the air supply angle of the air conditioner 100 according to personal needs. In particular, when the air conditioner 100 is in the heating mode, the outlet end 211 of the volute 2 faces downward and under the action of the volute tongue 22, the hot air discharged through the outlet end 211 of the volute 2 is more inclined to be supplied directly downward. At this time, the outlet air guide section 5 has a smaller angle with respect to the default air outlet direction of the air guide duct 23, which reduces the air volume loss caused by the outlet air guide section 5, and ensures that the heating air supply has a larger air volume and a favorable wind direction at the same rotation speed of the wind wheel 3, which is conducive to the hot air being blown to the ground, and further helps to improve the thermal comfort of the indoor environment.

[0039] According to the air conditioner 100 of the embodiment of the present invention, the volute tongue 22 is connected to the lower surface of the volute body 21, and the volute 2 is rotatable around the central axis of the wind wheel 3. In the cooling mode, the volute tongue 22 cooperates with the upper end of the outlet air guide section 5, and in the heating mode, the volute 2 can be rotated to be separated from the outlet air guide section 5 and the outlet end 211 of the volute 2 faces downward. Therefore, the user can adjust the rotation angle of the volute 2 relative to the wind wheel 3 according to personal needs to adjust the air supply angle of the air conditioner 100, especially when the air conditioner 100 is in the heating mode. In the heat mode, the outlet end 211 of the volute 2 is oriented downward and the hot air discharged through the outlet end 211 of the volute 2 under the action of the volute tongue 22 is more inclined to be delivered directly downward. At this time, the outlet air guide section 5 has a smaller angle with respect to the default air outlet direction of the air guide duct 23, which reduces the air volume loss caused by the outlet air guide section 5, and ensures that the heating air supply has a larger air volume and a favorable wind direction at the same speed of the wind wheel 3, so that the hot air is blown to the ground, and thus it is beneficial to improve the thermal comfort of the indoor environment. Specifically, when the air conditioner 100 is installed at a height greater than 2.5m, such as 2.8m, it can blow the air to the ground during heating, which is beneficial to improve the thermal comfort of the room.

[0040] In some embodiments of the present invention, Figure 3 As shown, the rotation angle of the volute 2 is α, and the value range of α is 0≤α≤70°. For example, when the air conditioner 100 switches from cooling mode to heating mode, the rotation angle α of the volute 2 can be 0°, 20°, 40°, 60° or 70°. Therefore, when the air conditioner 100 is heating, it is beneficial to ensure that the outlet air guide section 5 has a smaller angle with respect to the default air outlet direction of the air guide duct 23, thereby reducing the air volume loss caused by the outlet air guide section 5, and ensuring that the heating air supply has a larger air volume and a favorable wind direction at the same speed of the wind wheel 3, which is conducive to the hot air blowing to the ground. Of course, the specific value of α can be adjusted and designed according to the specific model of the air conditioner 100, and the present invention does not make specific limitations on this.

[0041] In some embodiments of the present invention, reference Figure 1-Figure 3As shown, the bottom wall of the housing 1 is provided with a stop protrusion 13, and in the heating mode, the volute tongue 22 contacts the stop protrusion 13. Therefore, when the air conditioner 100 switches from the cooling mode to the heating mode, the volute 2 stops rotating when the volute tongue 22 contacts the stop protrusion 13, thereby achieving the position limitation of the volute 2, and the structure is simple, which is conducive to reducing the manufacturing cost.

[0042] Specifically, in the heating mode, the volute tongue 22 is located at the front side of the stop protrusion 13. Figure 2 and Figure 3 As shown, the stop protrusion 13 is provided on the bottom wall of the housing 1 and extends vertically upward, and in the heating mode, the volute tongue 22 is located in front of the stop protrusion 13, and the rear wall of the volute tongue 22 contacts the front wall of the stop protrusion 13. Thus, it is beneficial to improve the limiting effect of the stop protrusion 13 on the volute tongue 22, and at the same time, it can avoid the occurrence of air leakage, and ensure that the volute tongue 22 can guide all the air out of the housing 1, so as to improve the reliability of the operation of the air conditioner 100.

[0043] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the top wall of the housing 1 is provided with a limiting protrusion 14, and in the cooling mode, the outer peripheral wall of the volute 2 contacts the limiting protrusion 14. Figure 2 As shown, the limiting protrusion 14 is provided on the inner top wall of the housing 1 and extends vertically downward. In the cooling mode, the outer peripheral wall of the volute 2 contacts the lower end of the limiting protrusion 14. Therefore, when the air conditioner 100 switches from the heating mode to the cooling mode, the volute 2 stops rotating when the outer peripheral wall of the volute 2 contacts the limiting protrusion 14, thereby achieving the limiting of the volute 2. The structure is simple, which is conducive to reducing the manufacturing cost.

[0044] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the air conditioner 100 further includes an air guide assembly 6 rotatably disposed at the outlet end 211 of the air guide duct 23, and the rotation of the volute 2 drives the air guide assembly 6 to rotate. Figure 1 As shown, the air guide assembly 6 includes an air guide plate and a rotating shaft, the rotating shaft passes through the air guide plate and the two ends of the rotating shaft are pivotally arranged on the volute 2, and the rotation of the volute 2 drives the air guide assembly 6 to rotate. Therefore, the air outlet direction of the outlet end 211 of the air guide duct 23 can be adjusted by adjusting the rotation angle of the air guide assembly 6, which is conducive to increasing the air supply range of the air conditioner 100. When the air conditioner 100 is in the heating mode, the air guide assembly 6 can also be used in conjunction with the air outlet guide section 5, which is conducive to further increasing the air supply range of the air conditioner 100. It can be understood that when the air conditioner 100 stops working, the air guide assembly 6 closes the outlet end 211 of the air guide duct 23 to prevent debris from entering the air guide duct 23.

[0045] In some embodiments of the present invention, reference Figure 1-Figure 3As shown, the wind wheel 3 is a centrifugal wind wheel 3. This is beneficial to increasing the wind pressure and wind volume in the wind guide duct 23, thereby ensuring the air supply distance of the air conditioner 100.

[0046] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the air inlet 11 is arranged on the bottom wall of the housing 1. Thus, it is convenient for indoor air to enter the housing 1 through the air inlet 11.

[0047] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the outlet air guide section 5 is rotatably disposed on the housing 1. For example, a pivot shaft is disposed on the outlet air guide section 5, the pivot shaft is passed through the outlet air guide section 5, and both ends of the pivot shaft are pivotally disposed on the housing 1, so that the outlet air guide section 5 can rotate relative to the housing 1. Therefore, the outlet direction of the airflow of the air guide duct 23 can be adjusted by adjusting the rotation angle of the outlet air guide section 5, which is beneficial to increase the air supply range of the air conditioner 100.

[0048] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the lower end of the indoor heat exchanger 4 is placed in the water receiving pan 7. For example, the indoor heat exchanger 4 can be placed vertically or tilted in the housing 1, and the lower end of the indoor heat exchanger 4 is placed in the water receiving pan 7, and the lower end of the water receiving pan 7 is connected to the housing 1. It can be understood that, during the operation of the indoor heat exchanger 4, when the air is cooled, water droplets will liquefy on the surface of the indoor heat exchanger 4, and the water droplets will flow along the indoor heat exchanger 4 to the lower end of the indoor heat exchanger 4, and the water receiving pan 7 can play a role in guiding the water flow at the lower end of the indoor heat exchanger 4 to flow out of the air conditioner 100.

[0049] Reference below Figure 1-Figure 3 The specific structure of the air conditioner 100 of the present invention is described in detail.

[0054] The driving motor is arranged in the installation cavity 15 and the motor shaft of the driving motor is connected to the volute 2. The central axis of the motor shaft and the central axis of the wind wheel 3 are on the same straight line. The driving motor can drive the volute 2 to rotate around the central axis of the wind wheel 3. In the cooling mode, the volute tongue 22 cooperates with the upper end of the outlet air guide section 5; in the heating mode, the volute 2 rotates to separate from the outlet air guide section 5, and the outlet of the volute 2 faces downward, and the outlet air guide section 5 is located in the air guide duct 23.

[0055] like Figure 1-Figure 3 As shown, the bottom wall of the housing 1 is provided with a stop protrusion 13, and in the heating mode, the volute tongue 22 contacts the stop protrusion 13. Specifically, the volute tongue 22 is located at the front side of the stop protrusion 13 in the heating mode.

[0056] like Figure 1-Figure 3 As shown, a limiting protrusion 14 is provided on the top wall of the shell 1 , and in the cooling mode, the outer peripheral wall of the volute 2 contacts the lower end of the limiting protrusion 14 .

[0057] Reference Figure 1-Figure 3 As shown, the air conditioner 100 further includes an air guide assembly 6 rotatably disposed at the outlet end 211 of the air guide duct 23, and the rotation of the volute 2 drives the air guide assembly 6 to rotate. Specifically, the air guide assembly 6 includes an air guide plate and a rotating shaft, the rotating shaft passes through the air guide plate and both ends of the rotating shaft are pivotally disposed on the body of the volute 2, and the rotation of the volute 2 drives the air guide assembly 6 to rotate.

[0058] like Figure 1-Figure 3 As shown, the indoor heat exchanger 4 is placed vertically and the lower end of the indoor heat exchanger 4 is placed in the water receiving tray 7, and the lower end of the water receiving tray 7 is connected to the shell 1.

[0059] Combination Figure 2 and Figure 3 As shown, Figure 3 As shown, when the air conditioner 100 switches from the cooling mode to the heating mode, the rotation angle of the volute 2 is α, α=45°.

[0060] Specifically, if Figure 1As shown, when the air conditioner 100 stops working, the air guide assembly 6 closes the outlet end 211 of the air guide duct 23 to prevent debris from entering the air guide duct 23; Figure 2 As shown, when the air conditioner 100 is in cooling mode, the volute tongue 22 is connected to the upper end of the outlet air guide section 5 so that the cold air in the air guide duct 23 is blown out in a horizontal direction, thereby realizing the circulation of the cold air from top to bottom in the indoor environment, which is beneficial to improving the user experience; Figure 3 As shown, when the air conditioner 100 is in the heating mode, the driving motor drives the volute 2 to rotate until it is separated from the outlet air guide section 5 and the outlet end 211 of the volute 2 is downward and the outlet air guide section 5 is located in the air guide duct 23, so that the hot air in the air guide duct 23 can be blown out downward. At this time, the outlet air guide section 5 has a smaller angle with respect to the default air outlet direction of the air guide duct 23, which reduces the air volume loss caused by the outlet air guide section 5, and ensures that the heating air supply has a larger air volume and a favorable wind direction at the same rotation speed of the wind wheel 3, which is conducive to the hot air being blown to the ground, and the hot air can be circulated from bottom to top in the indoor environment, which is beneficial to improving the thermal comfort of the indoor environment.
