Description

Technical Field

[0001] This disclosure relates to the field of air conditioner technology, and more specifically, to an air conditioner. Background Technology

[0002] In related technologies, indoor air conditioners consist of a fan, air inlet, air outlet, and heat exchanger. They deliver air for cooling and heating through a guide vane. However, the aforementioned air delivery method is limited in its single air delivery pattern, making it difficult to meet the requirements of cold air being delivered from top to bottom during cooling and hot air being delivered from bottom to top during heating. This can easily lead to problems such as cold air blowing directly on people and hot air not being able to reach the ground during air conditioner operation, resulting in poor user comfort. Utility Model Content

[0003] The purpose of this disclosure is to provide an air conditioner capable of reversibly supplying air between a first opening and a second air outlet, so as to at least partially solve the problems in the related art.

[0004] To overcome the problems existing in the related art, a first aspect of the present disclosure provides an air conditioner, including: a housing comprising a first chamber and a second chamber. The first chamber is equipped with a heat exchanger and a first opening communicating with the outside. The second chamber is equipped with a vortex fan that can rotate forward or backward. The first air outlet of the vortex fan is connected to the first chamber, and the second air outlet of the vortex fan is connected to the outside. The first opening and the second air outlet have different orientations.

[0005] In some possible implementations, one of the first opening and the second air outlet is located on the side wall of the housing, and the other is located on the top or side wall of the housing. Thus, by having one of the first openings and the second air outlet on the side of the housing and the other on the bottom or top wall, a bottom-inlet, side-outlet air supply method or a side-inlet, bottom-outlet air supply method can be formed, replacing the single air outlet method of air conditioners in related technologies and improving the user experience.

[0006] In some possible implementations, the first opening is located on the side wall of the housing, and the second air outlet is located on the bottom wall of the housing. This allows for either a bottom-inlet, side-outlet air supply method or a side-inlet, bottom-outlet air supply method, adapting to the air supply conditions of the air conditioner's heating and cooling modes. Specifically, during cooling, the bottom-inlet, side-outlet configuration allows cold air to flow from top to bottom, while during heating, the bottom-outlet, side-inlet configuration allows hot air to flow from bottom to top, thereby improving the user experience.

[0007] In some possible implementations, the air conditioner includes a first air supply state and a second air supply state. In the first air supply state, the fan in the vortex fan rotates forward, and air enters through the second air outlet and exits through the first opening. In the second air supply state, the fan in the vortex fan rotates in reverse, and air enters through the first opening and exits through the second air outlet. Thus, the first and second air supply states of the air conditioner can be adjusted by rotating the fan in the fan assembly forward and in reverse, allowing the air conditioner to supply air through the first opening in the first air supply state, or through the second air outlet in the second air supply state.

[0008] In some possible implementations, the air conditioner further includes a diffuser structure disposed in the second chamber. The diffuser structure is connected to the first air outlet and / or the second air outlet. The diffuser structure connected to the first air outlet diffuses from the first air outlet toward the first chamber, while the diffuser structure connected to the second air outlet diffuses from the second air outlet toward the second chamber. Thus, when the diffuser structure is connected to the first air outlet, it diffuses from the first air outlet toward the first chamber. Therefore, when air is discharged from the first outlet, the diffuser structure can decelerate the high-speed airflow discharged by the vortex fan, converting kinetic energy into static pressure, thereby improving the air delivery distance and uniformity. When the diffuser structure is connected to the second air outlet, it diffuses from the second air outlet toward the second chamber. Therefore, when air is discharged from the second air outlet, it can decelerate the high-speed airflow discharged by the vortex fan, converting kinetic energy into static pressure, thereby improving the air delivery distance and uniformity.

[0009] In some possible implementations, the diffuser structure includes a diffuser section whose cross-sectional area gradually increases from a first end toward a second end. The first end of the diffuser section is connected to either the first or second air outlet, and the second end is connected to either the first or second chamber. This specifically defines the structure of the diffuser section, where the cross-sectional area gradually increases from the first end toward the second end, and the first end is connected to either the first or second air outlet, while the second end is connected to either the first or second chamber. This allows the air discharged through the first or second air outlet of the vortex fan to be decelerated by the diffuser, converting kinetic energy into static pressure, improving the air delivery distance and uniformity. The air passing through the diffuser section is ultimately discharged through either the first opening connected to the first chamber or the second air outlet.

[0010] In some possible implementations, the diffuser structure includes two diffuser sections. One diffuser section has its first end connected to the first air outlet and its second end connected to the first chamber. The other diffuser section has its first end connected to the second air outlet and its second end connected to the outside through the second chamber. Thus, in both the first and second air outlet states of the air conditioner, the diffuser section in the diffuser structure can diffuse the air, thereby slowing down the high-speed airflow discharged by the vortex fan when the air is discharged from the first or second air outlet, converting kinetic energy into static pressure, and improving the air delivery distance and uniformity.

[0011] In some possible implementations, the air conditioner further includes a first duct and a second duct, with the first ends of the first duct and the second duct respectively connected to the first air outlet and the second air outlet, and the second ends of the first duct and the second duct respectively connected to the corresponding diffuser. Thus, the arrangement of the first duct and the second duct allows for a smooth transition of air discharged from the first and second air outlets of the vortex fan, guiding it to the corresponding diffuser for diffusion before discharge.

[0012] In some possible implementations, there are multiple vortex fans arranged side by side. The first air outlet of each vortex fan communicates with the first chamber, and the second air outlet of each vortex fan communicates with the outside through the second chamber. Thus, by arranging multiple vortex fans side by side, the total air volume of the air conditioner can be increased. Furthermore, the load on a single vortex fan can be reduced, extending the service life of the air conditioner.

[0013] In some implementable embodiments, the air conditioner further includes a drip tray disposed in the first chamber and below the heat exchanger; and / or The air conditioner also includes an auxiliary heating element, which is located in the first chamber and spaced apart from the heat exchanger. This design, with its drip tray, collects and drains condensate, preventing leakage to the fan and thus avoiding electrical malfunctions, ensuring stable operation of the air conditioner. Furthermore, the auxiliary heating element supplements heating, ensuring effective indoor temperature control and improving user experience.

[0014] In some feasible implementations, the air conditioner is a ducted unit. This limits the application scenarios of the air conditioner to those of a ducted unit.

[0015] The above technical solution involves an air conditioner housing comprising a first chamber and a second chamber. The first chamber has a first opening communicating with the outside and a heat exchanger. The second chamber has a reversible vortex fan. The first air outlet of the vortex fan is connected to the first chamber, and the second air outlet is connected to the outside. The first opening and the second air outlet face different directions. Thus, the reversible air supply of the air conditioner is achieved by rotating the vortex fan, i.e., selectively supplying air through the first opening or the second air outlet, thereby improving the user experience.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower of the corresponding figures, as detailed in the figures. Figures 1 to 3 The arrows point in the direction of the lines. The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not indicate sequence or importance. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] The inventors discovered that indoor air conditioners consist of a fan, air inlet, air outlet, and heat exchanger, and deliver air during cooling and heating through a guide vane. However, the aforementioned air delivery method is limited in its single air delivery pattern, making it difficult to meet the requirements of cold air being delivered from top to bottom during cooling and hot air being delivered from bottom to top during heating. This can easily lead to problems such as cold air blowing directly on people and hot air not being able to reach the ground during air conditioner operation, resulting in poor user comfort.

[0025] To solve the above technical problems, such as Figures 1 to 3 As shown, this disclosure provides an air conditioner, including: a housing 1, a heat exchanger 2, and a vortex fan 3, wherein the housing 1 includes a first chamber 11 and a second chamber 12, the heat exchanger 2 is disposed in the first chamber 11, the first chamber 11 includes a first opening 13 communicating with the outside, the vortex fan 3 is configured to be able to rotate forward or reverse and is disposed in the second chamber 12, the first air outlet 31 of the vortex fan 3 is communicating with the first chamber 11, the second air outlet 32 ​​of the vortex fan 3 is communicating with the outside, and the first opening 13 and the second air outlet 32 ​​have different orientations.

[0026] Through the above technical solution, the housing 1 of the air conditioner includes a first chamber 11 and a second chamber 12. The first chamber 11 is provided with a first opening 13 communicating with the outside and a heat exchanger 2. The second chamber 12 is provided with a vortex fan 3 that can rotate forward or backward. The first air outlet 31 of the vortex fan 3 is connected to the first chamber 11, and the second air outlet 32 ​​is connected to the outside. The first opening 13 and the second air outlet 32 ​​have different orientations. Thus, the air conditioner can achieve reversible air supply by rotating the vortex fan 3 forward or backward, that is, the air inlet and outlet of the air conditioner can be switched. The air conditioner can supply air through the first opening 13 or through the second air outlet 32, so that the room where the air conditioner is used can selectively supply air according to different operating conditions, thereby improving the user experience.

[0027] In some possible implementations, one of the first opening 13 and the second air outlet 32 ​​is located on the side wall of the housing 1, and the other is located on the bottom wall of the housing 1. For example, the housing 1 can be a rectangular box, with a partition 14 dividing the housing 1 into a first chamber 11 and a second chamber 12 in the middle. The first opening 13 can be located on the front side wall of the housing 1, and the second air outlet 32 ​​can be located on the bottom wall of the housing 1. Here, the top wall refers to the side wall of the housing 1. Figure 1 For details of the upper sidewall and bottom wall of the middle shell 1, please refer to [reference needed]. Figure 1On the lower side wall of the middle shell 1, the second air outlet 32 ​​is located below the first opening 13. Thus, when the air conditioner is heating, the rotation of the vortex fan 3 can be controlled to allow indoor air to enter through the first opening 13 and exit through the second air outlet 32. At this time, the hot air is discharged from the bottom to the top when the air conditioner is heating. The hot air has a lower density and will naturally rise. The hot air rises and the cold air sinks. The bottom air outlet can form a complete convection cycle, allowing the heat to evenly cover the entire space and preventing the hot air from directly accumulating on the ceiling. The heating efficiency is improved. In addition, the bottom air outlet can also reduce the temperature difference between the top and bottom caused by the single top air outlet, improving the user experience. When the air conditioner is cooling, the direction of the vortex fan 3 can be controlled to allow indoor air to enter through the second air outlet 32 ​​and exit through the first opening 13. At this time, the cold air is discharged from top to bottom when the air conditioner is cooling. The cold air is dense and will naturally sink after being discharged from the top. Together with the air intake from the bottom, it forms a complete convection cycle, which makes the indoor space cool down quickly. In addition, the cold air diffuses from top to bottom, avoiding local areas from being too cold or too hot, reducing the temperature difference and improving the user experience.

[0028] It is understood that the air conditioner casing 1 is located indoors, and the air conditioner also includes an outdoor unit. The outdoor unit includes a compressor, an outdoor heat exchanger, and a four-way valve. When the air conditioner is cooling, the compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, which flows through the outdoor unit's heat exchanger (condenser). After releasing heat to the outside, it liquefies into a high-pressure liquid. The pressure is reduced by the expansion valve, turning it into a low-temperature, low-pressure mist liquid. The mist liquid flows through the indoor unit's heat exchanger 2 (evaporator), absorbing heat from the room and vaporizing, thus cooling the room. When the air conditioner is heating, the four-way valve switches the refrigerant flow. At this time, the indoor unit's heat exchanger becomes a condenser, and the outdoor unit's heat exchanger becomes an evaporator. The high-temperature, high-pressure gas compressed by the compressor first flows through the indoor unit's heat exchanger 2 (condenser), releasing heat to the room. After releasing heat, the liquefied refrigerant is depressurized by the expansion valve and then flows to the outdoor unit's heat exchanger (evaporator), absorbing heat from the outside and vaporizing. This cycle repeats to raise the indoor temperature.

[0029] Of course, it is understandable that the above-mentioned first opening 13 located on the side wall of the housing 1 and the second air outlet 32 ​​located on the bottom wall of the housing 1 are schematic. In other embodiments, the first opening 13 may be located on the bottom wall of the housing 1 and the second air outlet 32 ​​may be located on the side wall of the housing 1. In this case, the second air outlet 32 ​​is located above the first opening 13, which can also realize the air supply mode of the air conditioner with bottom air intake and top air outlet or top air intake and bottom air outlet, thereby adapting to different operating conditions of the air conditioner. For example, when the air conditioner is cooling or heating, by selecting different air outlet modes, the temperature in the room can drop or rise quickly, reducing the feeling of temperature difference and improving the user experience.

[0030] In some possible implementations, the air conditioner includes a first air supply state and a second air supply state. When the fan in the vortex fan 3 rotates forward, the air conditioner is in the first air supply state. At this time, the air conditioner receives air through the second air outlet 32 ​​and discharges air through the first opening 13. That is, the first air supply state corresponds to the cooling state of the air conditioner. The first air supply state can be referenced... Figure 2 When the fan in the fan assembly reverses, the air conditioner is in the second air supply state. At this time, the air conditioner discharges air from the second air outlet 32 ​​and receives air from the first opening 13. That is, the second air supply state corresponds to the heating state of the air conditioner. The second air supply state can be referred to... Figure 3 .

[0031] The vortex fan 3 features high air pressure, stable flow, reliable operation, and the ability to rotate in both directions. In some possible embodiments, the vortex fan 3 may include a volute, an impeller, and a motor that can rotate in both directions. The impeller is disposed inside the volute, and the motor drives the impeller to rotate in both directions. The volute is provided with a first air outlet 31 and a second air outlet 32. By driving the impeller to rotate in both directions, the motor selectively discharges air from the first air outlet 31 or the second air outlet 32, thereby adapting to the first and second air supply states of the air conditioner.

[0032] To optimize the uniformity of airflow and increase the air delivery distance during air supply in the air conditioner, in some possible embodiments, the air conditioner further includes a diffuser structure 4 disposed in the second chamber 12. The diffuser structure 4 is connected to the first air outlet 31 and / or the second air outlet 32. The diffuser structure 4 connected to the first air outlet 31 diffuses from the first air outlet 31 toward the first chamber 11, while the diffuser structure 4 connected to the second air outlet 32 ​​diffuses from the second air outlet 32 ​​toward the second chamber 12. Figure 1 As shown, the diffuser structure 4 is connected to the first air outlet 31 and the second air outlet 32 ​​respectively. Thus, when the air conditioner is in the first air supply state, the air conditioner supplies air through the first opening 13. At this time, the air is discharged from the first air outlet 31 of the vortex fan 3 and enters the first opening 13 on the front side wall of the first chamber 11 through the corresponding diffuser structure 4 and is discharged. The diffuser structure 4 can increase the cross-sectional area of ​​the air discharged from the first air outlet 31 of the vortex fan 3, thereby reducing the flow velocity and reducing the local loss caused by the sudden increase in the flow area due to the direct supply to the room through the first opening 13. At the same time, it converts the kinetic energy of the air into static pressure, so that the air supply of the air conditioner is more uniform and the air supply distance is longer in the first air supply state. Similarly, when the air conditioner is in the second air supply state, the diffuser structure 4 can reduce the air velocity discharged from the second air outlet 32 ​​of the vortex fan 3, reduce the local loss caused by the sudden increase in the circulation area due to direct discharge into the room, and convert the kinetic energy of the air into static pressure, so that the air supply is more uniform and the air supply distance is longer when the air conditioner is in the first air supply state.

[0033] It is understood that the above-mentioned configuration of the diffuser structure 4 to be connected to the first air outlet 31 and the second air outlet 32 ​​is illustrative. In other embodiments, the diffuser structure 4 can also be selected according to different operating conditions. For example, it can be connected to the first air outlet 31 alone, or the diffuser structure 4 can be connected to the second air outlet 32 ​​alone.

[0034] like Figures 1 to 3 As shown, specifically, the diffuser structure 4 may include a diffuser section 41. The cross-section of the diffuser section 41 gradually increases from the first end of the diffuser section 41 toward the second end of the diffuser section 41, that is, the diffuser section 41 is flared from the first end to the second end, with the first end being the small diameter end and the second end being the large diameter end. The diffuser section 41 may be a conical cylinder with a circular bottom or a square pyramidal cylinder with a rectangular bottom. The first end of the diffuser section 41 is connected to the first air outlet 31 or the second air outlet 32, and the second end of the diffuser section 41 is connected to the first chamber 11 or the second chamber 12. At this time, a connection port may be provided on the partition 14 and the bottom plate of the second chamber 12. The second end of the diffuser section 41 is connected to the first chamber 11 through the connection port on the partition 14, or the second end of the diffuser section 41 is connected to the outside through the connection port on the bottom plate of the second chamber 12. Thus, when the air conditioner is in the first air supply state, air enters the vortex fan 3 through the second air outlet 32, and then enters the first chamber 11 through the first air outlet 31 and the diffuser 41, and is delivered to the room through the first opening 13. At this time, through the action of the diffuser 41, the cross-sectional area of ​​the air discharged from the first air outlet 31 is reduced, thereby reducing the flow velocity and reducing the local loss caused by the sudden increase in the flow area due to the direct delivery to the room through the first opening 13. At the same time, the kinetic energy of the air is converted into static pressure, thereby enabling the air conditioner to deliver air more evenly and for a longer distance in the first air supply state. Similarly, when the air conditioner is in the second air supply state, air enters the vortex fan 3 through the first opening 13 and is delivered to the room through the second air outlet 32 ​​and the diffuser 41. Thus, the diffuser 41 can reduce the flow velocity in the second air supply state, reducing the local loss caused by the sudden increase in the flow area due to the air being delivered directly to the room through the second air outlet 32. At the same time, it converts the kinetic energy of the air into static pressure, thereby enabling the air conditioner to deliver air more evenly and for a longer distance in the first air supply state.

[0035] In some possible implementations, the diffuser structure 4 may include two diffuser sections 41. One diffuser section 41 has its first end connected to the first air outlet 31 and its second end connected to the first chamber 11. The other diffuser section 41 has its first end connected to the second air outlet 32 ​​and its second end connected to the outside through the second chamber 12. This allows the airflow velocity discharged from the vortex fan 3 to be reduced through the corresponding diffuser section 41 when the air conditioner is in either the first or second air supply state. This reduces localized losses caused by the sudden increase in airflow area due to direct discharge into the room. Simultaneously, it converts the kinetic energy of the air into static pressure, resulting in more uniform airflow and a longer airflow distance in the first air supply state.

[0036] In order to ensure that the air discharged from the vortex fan 3 smoothly enters the corresponding diffuser 41, in some possible embodiments, the air conditioner further includes a first air duct 33 and a second air duct 34. The first ends of the first air duct 33 and the second air duct 34 are respectively connected to the first air outlet 31 and the second air outlet 32, and the second ends of the first air duct 33 and the second air duct 34 are respectively connected to the corresponding diffuser 41. Figure 1 As shown, the vortex blower 3 is installed in the second chamber 12. The vortex blower 3 can be fixedly connected to the top wall of the second chamber 12 via the bracket 35. The first air outlet 31 of the vortex blower 3 is provided with a first air duct 33, and the second air outlet 32 ​​is provided with a second air duct 34. The first air outlet 31 and the second air outlet 32 ​​on the vortex blower 3 can open on the same side and are spaced apart in the vertical direction. The first end of the first air duct 33 is connected to the first air outlet 31, and the second end of the first air duct 33 is connected to the first end of the corresponding diffuser 41. The first end of the second air duct 34 is connected to the second air outlet 32, and the second end of the second air duct 34 is connected to the first end of the corresponding diffuser 41. This allows the air from the first air outlet 31 of the vortex fan 3 to smoothly enter the corresponding diffuser 41, where its velocity is reduced. This reduces local losses caused by a sudden increase in the flow area due to direct exhaust into the room. Simultaneously, the kinetic energy of the air is converted into static pressure, resulting in more uniform airflow and a longer airflow distance during the first air supply state of the air conditioner. Similarly, the second air duct 34 smoothly guides the air from the second air outlet 32 ​​of the vortex fan 3 into the corresponding diffuser 41, where its velocity is reduced. This reduces local losses caused by a sudden increase in the flow area due to direct exhaust into the room. Simultaneously, the kinetic energy of the air is converted into static pressure, resulting in more uniform airflow and a longer airflow distance during the first air supply state of the air conditioner.

[0037] To increase the total air volume of the air conditioner, in some possible implementations, the number of vortex fans 3 is multiple, and the multiple vortex fans 3 are arranged side by side. The first air outlet 31 of each vortex fan 3 is connected to the first chamber 11, and the second air outlet 32 ​​of each vortex fan 3 is connected to the outside through the second chamber 12. For example, the number of vortex fans 3 can be two, and the two vortex fans 3 are arranged side by side in the second chamber 12. The first air outlet 31 of both vortex fans 3 is connected to the first chamber 11, and the second air outlet 32 ​​of both vortex fans 3 is connected to the outside through the second chamber 12. Thus, by arranging the two vortex fans 3 side by side, the total air volume of the air conditioner can be increased. In addition, the load on a single vortex fan can be reduced, extending the service life of the air conditioner.

[0038] Of course, it is understood that the number of two vortex fans 3 mentioned above is illustrative. In other embodiments, the number of vortex fans 3 can be selected according to specific operating conditions. In addition, the first air outlet 31 of each vortex fan 3 is connected to a diffuser 41, and the second air outlet 32 ​​of each vortex fan 3 is connected to a diffuser 41. Thus, when the air conditioner is in the first air supply state, the air conditioner supplies air through the first opening 13. At this time, the air is discharged from the first air outlet 31 of multiple vortex fans 3 and enters the first opening 13 on the front side wall of the first chamber 11 through the corresponding diffuser structure 4 and is discharged. The diffuser structure 4 can increase the cross-sectional area of ​​the air discharged from the first air outlet 31 of the vortex fan 3, thereby reducing the flow velocity and reducing the local loss caused by the sudden increase in the flow area due to the direct delivery to the room through the first opening 13. At the same time, the kinetic energy of the air is converted into static pressure, so that the air supply of the air conditioner is more uniform and the air supply distance is longer in the first air supply state. Similarly, when the air conditioner is in the second air supply state, the diffuser structure 4 can reduce the air velocity discharged from the second air outlet 32 ​​of the multiple vortex fans 3, reduce the local loss caused by the sudden increase in the circulation area due to direct discharge into the room, and at the same time, convert the kinetic energy of the air into static pressure, so that the air supply is more uniform and the air supply distance is longer when the air conditioner is in the first air supply state.

[0039] In some feasible embodiments, the air conditioner also includes a water collection tray 5, which is located in the first chamber 11 and below the heat exchanger 2. The water collection tray can collect condensate and guide it out of the drain, preventing condensate from leaking into the fan and causing electrical faults, thus ensuring the stable operation of the air conditioner.

[0040] In addition, the air conditioner also includes an auxiliary heating element 6, which is located in the first chamber 11 and spaced apart from the heat exchanger 2. The auxiliary heating element 6 can be an electric heating wire. The auxiliary heating element can supplement the heating capacity of the air conditioner in heating mode, especially in the initial stage of heating mode. The electric heating wire can quickly generate hot air to ensure the indoor temperature rise and improve the user experience.

[0041] In some feasible implementations, the air conditioner can be a ducted air conditioner. This ducted air conditioner incorporates all the beneficial effects of the aforementioned air conditioners.

[0042] Of course, the above-mentioned implementation of the air conditioner as a ducted air conditioner is illustrative. In other implementations, the air conditioner can also be a wall-mounted air conditioner or a cabinet air conditioner, etc.
