Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more particularly to an indoor air conditioning unit. Background Technology

[0002] When an air conditioner is heating, the relative humidity of the indoor air decreases, resulting in a poor user experience. Therefore, humidifying the indoor air becomes necessary when the air conditioner is heating. Existing humidification solutions for air conditioners include ultrasonic humidification, wet film humidification, steam humidification, and waterless humidification. Steam humidification is widely used because it can disinfect and sterilize.

[0003] However, the temperature of the steam delivered to the indoor unit of the air conditioner by the steam humidification component is currently too high, which can easily burn users. Utility Model Content

[0004] This application discloses an indoor air conditioning unit that can reduce the risk of users being scalded by steam.

[0005] To achieve the above objectives, this application discloses an indoor air conditioning unit, comprising:

[0006] The outer casing has a first air vent and a second air vent spaced apart on it, and the interior of the outer casing contains:

[0007] The first mixing chamber is connected to the first air outlet;

[0008] The second mixing chamber is connected to the second air outlet;

[0009] The fresh air duct is connected to the first mixing chamber and the second mixing chamber respectively;

[0010] The fresh air unit has its air outlet connected to the fresh air duct to deliver fresh air to the first air outlet and the second air outlet respectively;

[0011] A steam generating assembly having an outlet for outputting steam;

[0012] The flow divider has an air inlet, a first outlet, and a second outlet. The air inlet is connected to the air outlet of the steam generating assembly, the first outlet is connected to the first mixing chamber, and the second outlet is connected to the second mixing chamber.

[0013] In this application, the air inlet of the diverter is connected to the air outlet of the steam generating assembly, the first outlet of the diverter is connected to the first mixing chamber, the first mixing chamber is connected to the first air vent on the outer casing, the second outlet of the diverter is connected to the second mixing chamber, and the second mixing chamber is connected to the second air vent on the outer casing. Therefore, the diverter can divert the steam generated by the steam generating assembly to the first and second air vents on the outer casing, which can make the steam diffuse more evenly to various areas of the room, rather than concentrate it at a certain point, thereby expanding the coverage area of ​​the steam.

[0014] Furthermore, the first and second mixing chambers are connected to the fresh air duct, which in turn is connected to the fresh air unit. When the fresh air unit is working, it can supply fresh air to the first and second mixing chambers. The fresh air can mix with the steam in the first and second mixing chambers. Since the temperature of the fresh air is lower than that of the steam, the mixing of the fresh air with the steam can reduce the temperature of the steam, thereby reducing the risk of users being scalded by the steam ejected from the first and second air outlets.

[0015] In one alternative embodiment, the first outlet is positioned toward the first air vent, and the second outlet is positioned toward the second air vent.

[0016] Since the gas entering the first mixing chamber from the fresh air duct will be ejected through the first air outlet, the main airflow direction of the first mixing chamber is towards the first air outlet. And since the first outlet is set to face the first air outlet, the direction of the steam ejected from the first outlet is also towards the first air outlet. In other words, the direction of the steam ejected from the first outlet is consistent with the main airflow direction of the first mixing chamber. This can reduce turbulence and resistance, making the steam easier to be carried and dispersed by the fresh air. In this way, the steam can be more evenly integrated into the fresh air, thereby improving the uniformity of humidification.

[0017] In one alternative embodiment, the first air vent and the second air vent are located on opposite sides of the housing.

[0018] In this embodiment, the first air vent and the second air vent are located on opposite sides of the outer casing, so that steam can be discharged from opposite sides of the outer casing. Compared with steam being discharged from the same side or adjacent sides of the outer casing, this embodiment can make the steam diffuse more evenly to all corners of the room.

[0019] In one optional embodiment, the first outlet is disposed toward the first air vent, and the second outlet is disposed toward the second air vent;

[0020] Along the arrangement direction of the first outlet and the second outlet, the distance between the first outlet and the first air vent is equal to the distance between the second outlet and the second air vent.

[0021] In this embodiment, the distance between the first outlet and the first air vent is equal to the distance between the second outlet and the second air vent, so that the path length between the first outlet and the first air vent is equal to the path length between the second outlet and the second air vent. This makes the resistance of steam flow in the two paths equal, thereby making the amount of steam discharged from the first air vent and the second air vent consistent and improving the uniformity of steam distribution.

[0022] In one alternative embodiment, the steam generating assembly includes:

[0023] Water tank;

[0024] A heating box, wherein the heating box has the air outlet and the water inlet of the heating box is connected to the water tank;

[0025] A heater, wherein the heater is disposed inside the heating chamber;

[0026] A steam pipe, one end of which is connected to the air outlet and the other end of which is connected to the air inlet;

[0027] The steam pipe is positioned off-center from the space formed within the outer casing, along the center of the arrangement direction.

[0028] If the steam pipe is located in the middle of the space formed inside the casing along the arrangement direction, the space on both sides of the steam pipe has the same size along the arrangement direction. If components of different sizes need to be arranged in the space on both sides of the steam pipe, and the size of one component is larger than the size of the space on one side of the steam pipe, such as an electrical box and a water tank, where the size of the electrical box is larger than the size of the space on one side of the steam pipe, it will be not conducive to the layout of the components.

[0029] Therefore, in this embodiment, the steam pipe is positioned off-center from the space formed inside the outer casing along the arrangement direction. This allows the space on both sides of the steam pipe to have different dimensions, i.e., the space on one side of the steam pipe has a larger dimension, which can accommodate larger components, such as electrical boxes, while the space on the other side can accommodate smaller components, such as water tanks, thus facilitating the layout of components.

[0030] In one optional embodiment, the bottom surface of the inner wall of the diverter is a guide surface, which is used to guide the condensate located on the guide surface to the air inlet.

[0031] The condensate formed by steam condensation will drip onto the bottom surface of the inner wall of the distributor under its own gravity. In this embodiment, the bottom surface of the inner wall of the distributor is a guide surface, which can guide the condensate to the air inlet. The condensate at the air inlet will flow back to the heating box through the steam pipe. This can not only solve the problem of bacteria and mold, but also recover the condensate and reduce water consumption.

[0032] In one alternative embodiment, the diversion element includes:

[0033] The connecting pipe section is provided with a first interface, a second interface and the air inlet;

[0034] A first vent pipe, one end of which is connected to the first interface, and the other end of which has the first outlet;

[0035] The second vent pipe has one end connected to the second interface and the other end having the second outlet.

[0036] The angle between the first vent pipe and the second vent pipe is an obtuse angle.

[0037] In this embodiment, the angle between the first and second outlet pipes is an obtuse angle. When steam is diverted from the inlet of the connecting pipe section to the first and second outlet pipes, the change in flow direction is more gradual. This makes it less likely to generate turbulence, vortices, and local high-pressure areas, thereby reducing the resistance during steam flow and ensuring steam flow rate.

[0038] In one alternative embodiment, at least one of the first vent pipe and the second vent pipe is a rectangular tube.

[0039] In this embodiment, at least one of the first and second exhaust pipes is a rectangular pipe. Compared with a circular pipe, a rectangular pipe has a larger cross-sectional area and allows for a larger steam flow rate. Therefore, using a rectangular pipe for the first and / or second exhaust pipes in this embodiment can increase the steam flow rate.

[0040] In one alternative embodiment, at least one of the first outlet and the second outlet of the diverter forms a flared structure.

[0041] In this embodiment, at least one of the first outlet and the second outlet of the diverter forms a flared structure. The flared structure can effectively expand the diffusion angle of the steam, so that the steam can be more widely dispersed into the surrounding space when it is discharged, and thus enter the corresponding mixing chamber more evenly. This helps to improve the mixing efficiency of steam and fresh air, and makes the effects of humidification or air purification more evenly distributed in various areas of the room, avoiding situations where the local humidity is too high or too low.

[0042] In one optional embodiment, the housing is provided with a mounting structure, and a mounting space is formed within the mounting structure. The dimension of the mounting space along the width direction of the housing is a first dimension, and the first dimension of the mounting space gradually decreases from top to bottom.

[0043] The bottom of the diverter is installed within the installation space, and the shape of the bottom of the diverter is adapted to the shape of the installation space.

[0044] In this embodiment, the first dimension of the installation space gradually decreases from top to bottom, and the bottom shape of the diverter is adapted to this dimension. This adapted shape design allows the diverter to be more smoothly embedded into the installation space during installation, eliminating the need for additional positioning structures and effectively reducing the installation difficulty and saving installation time. Furthermore, because the size of the installation space gradually decreases from top to bottom, the diverter can be easily snapped into the installation space after it is installed. In other words, the installation structure can fix the diverter through its own shape without the need for additional fasteners such as screws or clips, thus effectively reducing the installation difficulty and saving installation time.

[0062] When an air conditioner is heating, the relative humidity of the indoor air decreases, resulting in a poor user experience. Therefore, humidifying the indoor air becomes necessary when the air conditioner is heating. Existing humidification solutions for air conditioners include ultrasonic humidification, wet film humidification, steam humidification, and waterless humidification. Steam humidification is widely used because it can disinfect and sterilize.

[0063] However, the temperature of the steam delivered to the indoor unit of the air conditioner by the steam humidification component is currently too high, which can easily burn users.

[0064] This application provides an air conditioner indoor unit that can reduce the risk of users being scalded by steam. The air conditioner indoor unit provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0065] like Figures 1 to 6 As shown in the embodiment of this application, an indoor unit of an air conditioner includes:

[0066] The outer casing 100 has a first air vent 101 and a second air vent 102 spaced apart on it, and the outer casing 100 contains:

[0067] The first mixing chamber 103 is connected to the first air outlet 101, and the gas in the first mixing chamber 103 can be discharged into the room through the first air outlet 101.

[0068] The second mixing chamber 104 is connected to the second air outlet 102, and the gas in the second mixing chamber 104 can be discharged into the room through the second air outlet 102.

[0069] Fresh air duct 105 is connected to the first mixing chamber 103 and the second mixing chamber 104 respectively. Part of the gas in the fresh air duct 105 will enter the first mixing chamber 103 and the other part of the gas will enter the second mixing chamber 104.

[0070] The fresh air unit 200 has its air outlet connected to the fresh air duct 105 to deliver fresh air to the first air outlet 101 and the second air outlet 102, respectively. Specifically, the air inlet of the fresh air unit 200 can be connected to the outside, thereby introducing outdoor air into the fresh air duct 105 and exhausting it into the room from the first air outlet 101 and the second air outlet 102, respectively.

[0071] The steam generating assembly 300 has an outlet for outputting steam. The steam generating assembly 300 is capable of generating steam, and the generated steam is discharged from the outlet.

[0072] The diverter 400 has an air inlet 401, a first outlet 402, and a second outlet 403. The air inlet 401 is connected to the air outlet of the steam generating assembly 300, the first outlet 402 is connected to the first mixing chamber 103, and the second outlet 403 is connected to the second mixing chamber 104. Specifically, since the air inlet 401 is connected to both the first outlet 402 and the second outlet 403, steam enters the diverter 400 from the air inlet 401 and exits from both the first outlet 402 and the second outlet 403, then enters the first mixing chamber 103 and the second mixing chamber 104, respectively.

[0073] In this application, the air inlet 401 of the diverter 400 is connected to the air outlet of the steam generating assembly 300, the first outlet 402 of the diverter 400 is connected to the first mixing chamber 103, the first mixing chamber 103 is connected to the first air vent 101 on the outer casing 100, the second outlet 403 of the diverter 400 is connected to the second mixing chamber 104, and the second mixing chamber 104 is connected to the second air vent 102 on the outer casing 100. Therefore, the diverter 400 can divert the steam generated by the steam generating assembly 300 to the first air vent 101 and the second air vent 102 on the outer casing 100. This allows the steam to be more evenly diffused to various areas of the room, rather than concentrated at a certain point, thereby expanding the coverage area of ​​the steam.

[0074] Furthermore, the first mixing chamber 103 and the second mixing chamber 104 are respectively connected to the fresh air duct 105, which in turn is connected to the fresh air unit 200. When the fresh air unit 200 is working, it can supply fresh air to the first mixing chamber 103 and the second mixing chamber 104. The fresh air can mix with the steam in the first mixing chamber 103 and the second mixing chamber 104. Since the temperature of the fresh air is lower than that of the steam, the mixing of the fresh air and the steam can reduce the temperature of the steam, thereby reducing the risk of the steam ejected from the first air outlet 101 and the second air outlet 102 scalding the user.

[0075] In one alternative embodiment, please refer to Figure 2 The first outlet 402 is set facing the first air vent 101, and the second outlet 403 is set facing the second air vent 102.

[0076] Since the gas entering the first mixing chamber 103 from the fresh air duct 105 will be ejected through the first air outlet 101, the main airflow direction of the first mixing chamber 103 is towards the first air outlet 101. Since the first outlet 402 is set to face the first air outlet 101, the direction of the steam ejected from the first outlet 402 is also towards the first air outlet 101. In other words, the direction of the steam ejected from the first outlet 402 is consistent with the main airflow direction of the first mixing chamber 103. This can reduce turbulence and resistance, making it easier for the steam to be carried and dispersed by the fresh air. In this way, the steam can be more evenly integrated into the fresh air, thereby improving the uniformity of humidification.

[0077] Similarly, since the gas entering the second mixing chamber 104 from the fresh air duct 105 will be ejected through the second air outlet 102, the main airflow direction of the second mixing chamber 104 is towards the second air outlet 102. By setting the second outlet 403 towards the first air outlet 101, the direction in which steam is ejected from the second outlet 403 is consistent with the main airflow direction of the second mixing chamber 104. This reduces turbulence and resistance, making it easier for the steam to be carried and dispersed by the fresh air. Thus, the steam can be more evenly integrated into the fresh air, thereby improving the uniformity of humidification. Of course, the first outlet 402 may not be oriented towards the first air outlet 101, and the second outlet 403 may not be oriented towards the second air outlet 102.

[0078] In one alternative embodiment, please refer to Figure 2 The first air vent 101 and the second air vent 102 are located on opposite sides of the outer casing 100, respectively.

[0079] In this embodiment, the first air vent 101 and the second air vent 102 are located on opposite sides of the outer casing 100, so that steam can be discharged from opposite sides of the outer casing 100. Compared with steam being discharged from the same side or adjacent sides of the outer casing 100, this embodiment can make the steam diffuse more evenly to all corners of the room.

[0080] In one optional embodiment, the first outlet 402 is disposed toward the first air inlet 101, and the second outlet 403 is disposed toward the second air inlet 102. Specifically, the direction in which steam is ejected from the first outlet 402 is consistent with the main airflow direction of the first mixing chamber 103. This reduces turbulence and resistance, making it easier for the steam to be carried and dispersed by the fresh air, thus allowing the steam to be more evenly integrated into the fresh air and improving the uniformity of humidification. The direction in which steam is ejected from the second outlet 403 is consistent with the main airflow direction of the second mixing chamber 104. This reduces turbulence and resistance, making it easier for the steam to be carried and dispersed by the fresh air, thus allowing the steam to be more evenly integrated into the fresh air and improving the uniformity of humidification.

[0081] Along the arrangement direction of the first outlet 402 and the second outlet 403, the distance between the first outlet 402 and the first air vent 101 is equal to the distance between the second outlet 403 and the second air vent 102. For example, the above arrangement direction can be parallel to the width direction of the housing 100.

[0082] If the distance between the first outlet 402 and the first air vent 101 is not equal to the distance between the second outlet 403 and the second air vent 102, then the path length between the first outlet 402 and the first air vent 101 is not equal to the path length between the second outlet 403 and the second air vent 102. The steam flow has less resistance in the shorter of the two paths, thus obtaining a larger flow rate. This results in one of the first air vents 101 and the second air vent 102 discharging more steam and the other discharging less steam, leading to uneven steam distribution.

[0083] Therefore, in this embodiment, the distance between the first outlet 402 and the first air vent 101 is equal to the distance between the second outlet 403 and the second air vent 102, so that the path length between the first outlet 402 and the first air vent 101 is equal to the path length between the second outlet 403 and the second air vent 102. This makes the resistance of steam flow in the two paths equal, thereby making the amount of steam discharged from the first air vent 101 and the second air vent 102 consistent and improving the uniformity of steam distribution.

[0084] In one alternative embodiment, the steam generating assembly 300 includes:

[0085] Water tank (not shown in the figure) is used to supply water to heating tank 310.

[0086] Heating box 310 has an air outlet and a water inlet connected to a water tank. Heating box 310 is the place where steam is generated.

[0087] A heater (not shown in the figure) is located inside a heating chamber 310, which is used to heat and evaporate the water inside the heating chamber 310 to generate steam.

[0088] A steam pipe (not shown in the figure) has one end connected to the air outlet and the other end connected to the air inlet 401. The steam pipe is located in the middle of the space formed inside the outer casing 100 along the arrangement direction.

[0089] If the steam pipe is located in the middle of the space formed inside the outer casing 100 along the arrangement direction, the space on both sides of the steam pipe has the same size along the arrangement direction. If components of different sizes need to be arranged in the space on both sides of the steam pipe, and the size of one component is larger than the size of the space on one side of the steam pipe, such as an electrical box and a water tank, where the size of the electrical box is larger than the size of the space on one side of the steam pipe, it will be not conducive to the layout of the components.

[0090] Therefore, in this embodiment, the steam pipe is positioned off-center from the space formed inside the outer casing 100 along the middle of the arrangement direction. This allows the space on both sides of the steam pipe to have different dimensions, that is, the space on one side of the steam pipe has a larger size, so that larger components, such as electrical boxes, can be accommodated, while smaller components, such as water tanks, can be arranged in the space on the other side, which is beneficial for the layout of components.

[0091] For example, the electrical box and the water tank are located on opposite sides of the steam pipe along the arrangement direction, and the size of the electrical box is larger than the size of the water tank along the arrangement direction.

[0092] During the process of steam being delivered to the room, the steam may condense in the diverter 400, producing condensate. If the condensate accumulates in the diverter 400 for a long time, it can generate bacteria and mold, posing a health hazard. To eliminate this health hazard, in an optional embodiment, the bottom surface of the inner wall of the diverter 400 is a guide surface 410, which is used to guide the condensate located on the guide surface 410 to the air inlet 401.

[0093] The condensate formed by steam condensation will drip onto the bottom surface of the inner wall of the diverter 400 under its own gravity. In this embodiment, the bottom surface of the inner wall of the diverter 400 is a guide surface 410. The guide surface 410 can guide the condensate to the air inlet 401. The condensate located at the air inlet 401 will flow back to the heating box 310 through the steam pipe. This can not only solve the problem of bacteria and mold, but also recover the condensate and reduce water consumption.

[0094] For example, the guide surface 410 includes a first wall surface 411 and a second wall surface 412 that are in contact with each other, as well as a third wall surface 413 and a fourth wall surface 414 that are in contact with each other. The first wall surface 411 is in contact with the first outlet 402, the second wall surface 412 is in contact with the air inlet 401, and the included angle between the first wall surface 411 and the second wall surface 412 is an obtuse angle; the third wall surface 413 is in contact with the second outlet 403, the fourth wall surface 414 is in contact with the air inlet 401, and the included angle between the third wall surface 413 and the fourth wall surface 414 is an obtuse angle.

[0095] In one alternative embodiment, please refer to Figures 4 to 6 The diversion component 400 includes:

[0096] The connecting pipe section 420 is provided with a first interface, a second interface and an air inlet 401. Steam discharged from the air outlet of the steam generating assembly 300 will enter the connecting pipe section 420.

[0097] The first vent pipe 430 has one end connected to the first interface and the other end has a first outlet 402. Some of the steam in the connecting pipe section 420 will enter the first vent pipe 430 and then enter the first mixing chamber 103 through the first outlet 402.

[0098] The second exhaust pipe 440 has one end connected to the second interface and the other end has a second outlet 403. Some of the steam in the connecting pipe section 420 will enter the second exhaust pipe 440 and then enter the second mixing chamber 104 through the second outlet 403.

[0099] The angle between the first vent pipe 430 and the second vent pipe 440 is an obtuse angle, that is, the angle between the axis of the first vent pipe 430 and the axis of the second vent pipe 440 is an obtuse angle.

[0100] In this embodiment, the angle between the first outlet pipe 430 and the second outlet pipe 440 is an obtuse angle. When steam is diverted from the inlet 401 of the connecting pipe section 420 to the first outlet pipe 430 and the second outlet pipe 440, the change in flow direction is more gradual. This makes it less likely to generate turbulence, vortices and local high-pressure areas, thereby reducing the resistance in the steam flow process and ensuring the steam flow rate.

[0101] In one alternative embodiment, please refer to Figure 4 At least one of the first vent pipe 430 and the second vent pipe 440 is a rectangular pipe.

[0102] In this embodiment, at least one of the first vent pipe 430 and the second vent pipe 440 is a rectangular pipe. Compared with a circular pipe, a rectangular pipe has a larger cross-sectional area and allows for a larger steam flow rate. Therefore, the use of a rectangular pipe for the first vent pipe 430 and / or the second vent pipe 440 in this embodiment can increase the steam flow rate.

[0103] In one alternative embodiment, please refer to Figure 4 and Figure 5 At least one of the first outlet 402 and the second outlet 403 of the diverter 400 forms a flared structure 450, that is, the cross-sectional area of ​​the diverter 400 at at least one of the first outlet 402 and the second outlet 403 gradually increases along the steam flow direction.

[0104] In this embodiment, at least one of the first outlet 402 and the second outlet 403 of the diverter 400 forms a flared structure 450. The flared structure 450 can effectively expand the diffusion angle of the steam, so that the steam can be more widely dispersed into the surrounding space when it is discharged, and thus enter the corresponding mixing chamber more evenly. This helps to improve the mixing efficiency of steam and fresh air, and makes the effects of humidification or air purification more evenly distributed in various areas of the room, avoiding the situation of excessively high or low local humidity.

[0105] In one alternative embodiment, please refer to Figure 2 The housing 100 is provided with an installation structure 110, and an installation space is formed within the installation structure 110. The dimension of the installation space along the width direction of the housing 100 is a first dimension, and the first dimension of the installation space gradually decreases from top to bottom.

[0106] The bottom of the diverter 400 is installed in the installation space, and the shape of the bottom of the diverter 400 is adapted to the shape of the installation space.

[0107] In this embodiment, the first dimension of the installation space gradually decreases from top to bottom, and the bottom shape of the diverter 400 is adapted to this dimension. This adapted shape design allows the diverter 400 to be more smoothly embedded into the installation space during installation, eliminating the need for additional positioning structures. This effectively reduces the installation difficulty of the diverter 400 and saves installation time. Furthermore, because the dimension of the installation space gradually decreases from top to bottom, the diverter 400 can be easily snapped into the installation space after it is installed. In other words, the installation structure 110 can fix the diverter 400 by its own shape without the need for additional fasteners such as screws or clips, thereby effectively reducing the installation difficulty of the diverter 400 and saving installation time.
