Description

Technical Field

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

[0002] As people's demands for quality of life continue to rise, air conditioning functions are becoming increasingly diversified. To improve indoor air humidity, some air conditioners have added steam humidification functions. In some new air conditioner designs, steam outlets are located on both sides of the unit casing, and steam is delivered into the room using fresh air intake.

[0003] However, in actual use, due to the location of the steam outlet and the fresh air traction method, steam can easily blow directly onto the wall, causing the wall to become damp and thus affecting the user experience. Utility Model Content

[0004] This application discloses a vertical air conditioner indoor unit that can reduce the risk of wall dampness, thereby improving the user experience.

[0005] To achieve the above objectives, this application discloses a vertical air conditioner indoor unit, comprising:

[0006] chassis;

[0007] The fresh air inlet is located on the casing.

[0008] A fresh air outlet is formed on the casing, and the fresh air outlet includes a first region and a second region, wherein the area of ​​the second region is smaller than the area of ​​the first region.

[0009] The volute is disposed inside the housing, and a volute fresh air inlet and a volute fresh air outlet are formed on the volute.

[0010] A fresh air fan is installed inside the volute. The fresh air fan rotates to drive fresh air into the volute from the fresh air inlet of the casing and the fresh air inlet of the volute, and blows it into the room through the fresh air outlet of the volute and the first area.

[0011] A humidification module, wherein the humidification module is used to generate steam, the humidification module includes:

[0012] A humidifying inlet component has a steam outlet, which is correspondingly arranged with the fresh air outlet of the casing, so that the steam is blown out through the steam outlet and the second area;

[0013] The housing includes:

[0014] An air outlet grille is obliquely disposed at the fresh air outlet of the housing, and the angle between the oblique direction of the air outlet grille and the width direction of the housing is α, where 35°≤α≤55°.

[0015] Since the area of ​​the second region is smaller than that of the first region, and fresh air is blown out from the first region while steam is blown out from the second region, when fresh air is blown out from the first region of the fresh air outlet of the casing, steam can be blown out from the second region of the fresh air outlet of the casing, reducing the diffusion of steam inside the casing and thus reducing the risk of overheating at the fresh air outlet of the casing.

[0016] If the angle between the tilt direction of the air outlet grille and the width direction of the casing is less than 35°, it means that the angle between the tilt direction of the air outlet grille and the width direction of the casing is small. In this case, when the casing installation requires the angle between the side wall of the casing and the wall to be about 45°, the fresh air and steam brought out through the air outlet grille will blow forward. If the user is close to the casing, the steam will blow directly onto the human body, which may cause a safety accident (because the steam temperature is high, if it blows directly onto the face or arms of the human body, there may be burns).

[0017] If the angle between the tilt direction of the air outlet grille and the width direction of the casing is greater than 55°, it means that the angle between the tilt direction of the air outlet grille and the width direction of the casing is large. In this case, the angle between the flow direction of the steam discharged through the air outlet grille and the wall may be close to 90°. As a result, there is still a risk that the steam will blow onto the wall.

[0018] Therefore, by taking all factors into consideration, when the angle between the tilt direction of the air outlet grille and the width direction of the casing is between 35° and 55°, the steam discharged through the air outlet grille will not blow directly onto the human body, thus avoiding safety accidents, and the angle between the airflow direction of the steam through the air outlet grille and the wall surface will be less than 90°, thereby reducing the risk of the steam guided by the air outlet grille blowing onto the wall surface.

[0019] In addition, since the indoor unit of a vertical air conditioner is usually installed near the corner of the wall, in order to reduce the fresh air blown from the fresh air outlet of the unit back onto the wall, the air outlet grille is tilted towards the front of the unit, and the angle between the tilt direction of the air outlet grille and the width direction of the unit is between 35° and 55°.

[0020] In one possible implementation, 42°≤α≤48°.

[0021] Therefore, when the angle between the tilt direction of the air outlet grille and the width direction of the casing is between 42° and 48°, the tendency of the airflow direction of the steam guided by the air outlet grille to be parallel to the wall can be further increased, thereby reducing the risk of steam blowing against the wall. At the same time, the angle between the airflow direction of the steam guided by the air outlet grille and the side wall of the casing is increased, further reducing the risk of steam blowing towards the human body.

[0022] In one possible implementation, α = 45°.

[0023] Therefore, when the angle between the tilt direction of the air outlet grille and the width direction of the casing is α = 45°, if the indoor unit of the vertical air conditioner is installed indoors according to the installation regulations, the steam discharged through the air outlet grille will be parallel to the wall. This can prevent the steam from blowing onto the wall and also prevent the steam from blowing onto the human body.

[0024] In one possible implementation, the air outlet grille includes at least two grille bars, which are spaced apart along the front-rear direction of the housing, and the at least two grille bars form a first air guide.

[0025] The fresh air outlet of the casing has the following characteristics along the front-rear direction of the casing:

[0026] The first side, the grid strip adjacent to the first side is the first grid strip, and the first grid strip on the first side forms a second guide port;

[0027] The second side is located behind the first side, and the grid bar adjacent to the second side is the second grid bar. A third flow guide is formed between the second side and the second grid bar.

[0028] The area opposite to the steam outlet of the first guide port is the second area, and the area where the first guide port is not opposite to the steam outlet, the second guide port, and the third guide port form the first area.

[0029] The first air guide is formed by arranging at least two grille bars at intervals along the front and rear direction of the casing, and the steam outlet is set opposite to the first air guide, thus constructing a directional channel for steam. That is, after the steam is discharged from the steam outlet, it can be directly and quickly discharged through the first air guide, reducing the residence time of steam inside the casing. Since fresh air can be discharged from the first air guide, the second air guide, and the third air guide, the effect of steam being discharged with fresh air can be guaranteed, thereby reducing the dispersion of steam inside the casing, while ensuring the consistency of the steam discharge direction with the fresh air discharge direction.

[0030] In one possible implementation, the housing has opposing first and second sidewalls along its width direction;

[0031] The fresh air outlet of the casing includes:

[0032] The first fresh air outlet is located on the first side wall;

[0033] The second fresh air outlet is located on the second side wall;

[0034] The steam outlet includes:

[0035] The first outlet, along the steam conveying direction, is located upstream of and opposite to the first fresh air outlet.

[0036] The second outlet, along the steam conveying direction, is located upstream of and opposite to the second fresh air outlet.

[0037] Since the first and second fresh air outlets are located on opposite sides of the casing along its width, with the first outlet inside and opposite to the first fresh air outlet, and the second outlet inside and opposite to the second fresh air outlet, the steam from the first outlet can be blown into the room along with the fresh air from the first outlet, and the steam from the second outlet can also be blown into the room along with the fresh air from the second outlet. Furthermore, the air outlet grille effectively guides the steam and fresh air passing through both the first and second fresh air outlets. This not only prevents steam from blowing directly onto the human body, reducing discomfort and the risk of burns, but also prevents steam from hitting the walls and causing dampness or damage. This balances safety and practicality, effectively improving the overall user experience.

[0038] Furthermore, the first and second fresh air outlets are respectively located on both sides of the casing width direction, which allows fresh air and steam to be blown into the room from the casing in two directions, improving the uniformity of heat dissipation of fresh air and steam, thereby improving the indoor air quality.

[0039] In one possible implementation, the distance between the steam outlet and the air outlet grille is d, where 5mm ≤ d ≤ 30mm.

[0040] If the distance between the steam outlet and the air outlet grille is less than 5mm, it means that the distance between the steam outlet and the air outlet grille is too close. This increases the difficulty of setting up the steam outlet and shortens the heat transfer distance between the heat in the steam and the casing. As a result, the heat in the steam can be directly transferred to the casing, which can easily cause the fresh air outlet of the casing to get hot and affect the user experience.

[0041] If the distance between the steam outlet and the air outlet grille is greater than 30mm, it indicates that the distance between the steam outlet and the air outlet grille is too large. This increases the travel distance of the steam from the steam outlet to the air outlet grille, causing a large amount of steam to diffuse between the steam outlet and the air outlet grille. On the one hand, this reduces the amount of steam passing through the air outlet grille, and on the other hand, it increases the risk of condensation forming in the fresh air outlet of the casing.

[0042] Based on this, the distance between the steam outlet and the air outlet grille is between 5mm and 30mm. This reduces the difficulty of setting up the steam outlet, avoids excessive heat at the fresh air outlet of the casing, and ensures the amount of steam passing through the fresh air outlet of the casing, thereby reducing the risk of condensation forming inside the fresh air outlet of the casing.

[0043] In one possible implementation, the humidification module further includes:

[0044] A humidifier, wherein the humidifier is disposed within the casing and is used to generate steam;

[0045] A humidifying pipe fitting, wherein the inlet end of the humidifying pipe fitting is connected to the humidifier, and the outlet end of the humidifying pipe fitting is connected to the humidifying inlet fitting.

[0046] Therefore, by connecting the humidifying pipe fittings to the humidifier and the humidifying inlet fitting respectively, on the one hand, it is convenient to introduce the steam in the humidifier into the humidifying inlet fitting. On the other hand, the humidifying pipe fittings can cause larger water droplets to settle down and be introduced into the humidifier during the process of guiding the steam, thereby reducing the amount of larger water droplets in the steam blown out from the fresh air outlet of the casing and improving the humidification effect of the air conditioner.

[0047] In one possible implementation, a fresh air duct is provided inside the housing, and the fresh air duct is connected to the fresh air outlet of the housing and the fresh air outlet of the volute respectively.

[0048] The humidification inlet includes:

[0049] The first air inlet is connected to the humidification pipe fitting;

[0050] The second air inlet is connected to the fresh air duct.

[0051] A steam pipe, the first end of which is connected to the first air inlet;

[0052] A gas mixing pipe, wherein the first end of the gas mixing pipe forms the steam outlet, the second end of the gas mixing pipe is connected to the second air inlet, and the second end of the steam pipe extends into the gas mixing pipe through the second end of the gas mixing pipe so that both the steam and fresh air in the gas mixing pipe are blown out through the steam outlet.

[0053] Therefore, the humidifier inlet unit obtains steam by connecting to the humidifier pipe fitting through the first air inlet, and introduces fresh air by connecting to the fresh air duct through the second air inlet. This allows the steam and fresh air to be fully mixed in the mixing pipe, and then blown out through the steam outlet. This reduces the temperature of the steam, thereby avoiding the accumulation of heat at the fresh air outlet of the casing and preventing overheating. It also improves the effect of guiding the steam into the room.

[0054] In addition, there is no specific limit to the depth at which the second end of the steam pipe extends into the mixed gas pipe, as long as the fresh air and steam can be fully and evenly mixed in the mixed gas pipe, and the fresh air can dissipate heat from the steam in the mixed gas pipe to avoid overheating at the fresh air outlet of the casing. Those skilled in the art can design the depth at which the second end of the steam pipe extends into the mixed gas pipe according to the steam flow rate and the fresh air flow rate.

[0055] In one possible implementation, the humidification inlet further includes an air guide plate disposed at the second air inlet for introducing fresh air into the second air inlet.

[0056] Therefore, by setting up a guide vane, the amount of fresh air introduced into the second air inlet can be increased, which has a significant effect on reducing the temperature of the steam in the mixed gas pipeline and guiding the steam through the air outlet grille.

[0057] In one possible implementation, the mixed gas duct includes a bottom wall that is inclined toward the bottom of the housing from the steam outlet toward the second air inlet, and the edge of the steam outlet toward the bottom of the housing is flush with the edge of the fresh air outlet of the housing.

[0058] Because the bottom wall is inclined towards the bottom of the casing from the steam outlet to the second air inlet, the condensation formed in the bottom wall due to the reduction of the steam temperature by the fresh air will be deposited on the bottom wall of the mixed gas pipe, and then introduced from the bottom wall towards the steam pipe, preventing the condensation from flowing out of the casing.

[0059] Furthermore, since the edge of the steam outlet facing the bottom of the casing is flush with the edge of the fresh air outlet of the casing, it can prevent condensation at the steam outlet and the fresh air outlet of the casing from flowing into the steam pipe along the bottom wall of the mixed gas pipe and finally being guided into the humidification pipe fittings by the steam pipe, thus solving the problem of condensation exposure and improving the user experience.

[0060] Compared with the prior art, the beneficial effects of this application are as follows:

[0061] When the angle between the tilt direction of the air outlet grille and the width direction of the casing is between 35° and 55°, the steam discharged through the air outlet grille will not blow directly onto the human body, thus avoiding safety accidents, and the angle between the airflow direction of the steam through the air outlet grille and the wall surface is less than 90°, thereby reducing the risk of the steam guided by the air outlet grille blowing onto the wall surface.

[0084] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0088] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0089] As described in the background section, some air conditioners have added steam humidification functions to improve indoor air humidity. In some newer air conditioner designs, the steam outlets are located on both sides of the unit casing, and the steam is delivered into the room using fresh air traction. However, in actual use, due to the location of the steam outlets and the method of fresh air traction, the steam can easily blow directly onto the walls, causing the walls to become damp and thus affecting the user experience.

[0090] Based on this, this application provides a vertical air conditioner indoor unit that can reduce the wind direction of damp walls, thereby improving the user experience.

[0091] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0092] See Figure 1 This application provides a vertical air conditioner indoor unit 100, which includes a housing 110.

[0093] The housing 110 can be round, square, or a combination of round and square, etc. The interior of the housing 110 is hollow, providing space for the installation of the fresh air module 120 and the humidification module 130.

[0094] In some possible embodiments, see Figure 1 , Figure 2 and Figure 7 The fresh air module 120 includes a housing fresh air inlet 121 and a housing fresh air outlet 122 formed on the housing 110.

[0095] The unit has a fresh air inlet 121 that is connected to the outdoor environment so that fresh air from the outside can enter the unit 110 through the fresh air inlet 121. The unit also has a fresh air inlet 121 that is connected to the indoor environment so that fresh air from the unit 110 can be blown into the room through the fresh air outlet 122 to improve indoor air quality.

[0096] In some possible embodiments, see Figure 3 The fresh air outlet 122 of the housing includes a first region 122a and a second region 122b. The area of ​​the second region 122b is smaller than that of the first region 122a. The fresh air module 120 also includes a volute 123 disposed within the housing 110 and a fresh air fan (not shown in the figure) disposed within the volute 123. The volute 123 also has a volute fresh air inlet 1231 and a volute fresh air outlet 1232. The fresh air fan is disposed within the volute 123. The fresh air fan rotates to drive fresh air into the volute 123 from the housing fresh air inlet 121 and the volute fresh air inlet 1231, and blows it into the room through the volute fresh air outlet 1232 and the first region 122a of the housing fresh air outlet 122.

[0097] The volute fresh air inlet 1231 is directly or indirectly connected to the housing fresh air inlet 121, and the volute fresh air outlet 1232 is directly or indirectly connected to the housing fresh air outlet 122. Thus, when the fresh air fan rotates, it can introduce outdoor fresh air into the volute 123 and drive the fresh air to enter the room through the housing fresh air outlet 122, thereby improving indoor air quality.

[0098] Optional, see Figure 3 and Figure 4 The fresh air module 120 also includes a fresh air duct 1233, which includes a first duct and a second duct. The first duct is formed inside the volute 123, and the second duct is formed between the volute 123 and the housing 110. Thus, the fresh air passing through the volute 123 can be blown into the room through the second duct and the first area 122a of the fresh air outlet 122 of the housing.

[0099] In some possible embodiments, see Figure 4The vertical air conditioner indoor unit 100 also includes a humidification module 130 disposed in the casing 110. The humidification module 130 is used to generate steam. The humidification module 130 includes a humidification inlet 131. The humidification inlet 131 has a steam outlet 1311. The steam outlet 1311 is correspondingly disposed with the second area 122b of the fresh air outlet 122 of the casing so that steam is blown out through the steam outlet 1311 and the second area 122b.

[0100] It should be noted that the steam outlet 1311 is correspondingly set to the second area 122b of the fresh air outlet 122 of the casing. It should be understood that the steam outlet 1311 is opposite to the second area 122b of the fresh air outlet 122 of the casing, and the steam outlet 1311 is located inside the casing 110.

[0101] Steam is generated by the humidification module 130 and can be blown out through the second area 122b of the fresh air outlet 122 of the casing. Normally, the fresh air outlet 122 of the casing is located on the side wall of the casing 110. However, when the vertical air conditioner indoor unit 100 is installed, the side wall of the casing 110 is installed at a 45° angle to the wall 200, and the fresh air outlet 122 of the casing is opposite to the wall 200. Thus, when the steam is blown out from the fresh air outlet 122 of the casing along with the fresh air, the fresh air and steam will be directly perpendicular to the wall 200. Over time, the wall 200 will become damp and moldy due to the intrusion of a lot of steam, which will seriously affect the user experience. Based on this, the structure of the casing 110 needs to be optimized, as follows.

[0102] Since the area of ​​the second region 122b is smaller than that of the first region 122a, and fresh air is blown out from the first region 122a while steam is blown out from the second region 122b, when fresh air is blown out from the first region 122a of the fresh air outlet 122 of the casing, steam can be blown out from the second region 122b of the fresh air outlet 122 of the casing, reducing the dispersion of steam in the casing 110 and thus reducing the risk of overheating at the fresh air outlet 122 of the casing.

[0103] In some possible embodiments, see Figure 1 and Figure 5 The housing 110 includes an air outlet grille 111, which is inclinedly disposed at the fresh air outlet 122 of the housing. The angle between the inclination direction of the air outlet grille 111 and the width direction of the housing 110 is α, where 35°≤α≤55°.

[0104] It should be noted that the tilt direction of the air vent grille 111 refers to the tilt of the air vent grille 111 towards the front side of the housing 110, such as... Figure 5 The direction indicated by arrow z1 is the tilt direction of the air outlet grille 111. The width direction of the casing 110 refers to the direction of the vertical air conditioner indoor unit 100 from left to right or from right to left, such as... Figure 5 The direction indicated by the Y-arrow is the width direction of the housing 110.

[0105] If the angle between the tilt direction of the air outlet grille 111 and the width direction of the housing 110 is less than 35°, it means that the angle between the tilt direction of the air outlet grille 111 and the width direction of the housing 110 is small. In this case, when the installation requirements of the housing 110 require that the angle between the side wall of the housing 110 and the wall 200 be about 45°, the fresh air and steam vented through the air outlet grille 111 will blow forward. If the user is close to the housing 110, the steam will blow directly onto the human body, which may cause a safety accident. Because the steam temperature is high, if it blows directly onto the face or arms of the human body, there may be burns.

[0106] If the angle between the tilt direction of the air outlet grille 111 and the width direction of the casing 110 is greater than 55°, it means that the angle between the tilt direction of the air outlet grille 111 and the width direction of the casing 110 is large. In this case, the angle between the flow direction of the steam discharged through the air outlet grille 111 and the wall 200 may be close to 90°. As a result, there is still a risk that the steam will blow towards the wall 200.

[0107] Therefore, by taking all factors into consideration, when the angle between the tilt direction of the air outlet grille 111 and the width direction of the casing 110 is between 35° and 55°, the steam discharged through the air outlet grille 111 will not blow directly onto the human body, thus avoiding safety accidents, and the angle between the airflow direction of the steam through the air outlet grille 111 and the wall surface 200 will be less than 90°, thereby reducing the risk of the steam guided by the air outlet grille 111 blowing onto the wall surface 200.

[0108] In addition, since the indoor unit 100 of the vertical air conditioner is usually installed near the corner of the wall, in order to reduce the fresh air blown from the fresh air outlet 122 of the casing blowing backward against the wall, the air outlet grille 111 is tilted toward the front of the casing 110, and the angle between the tilt direction of the air outlet grille 111 and the width direction of the casing 110 is between 35° and 55°.

[0109] Optionally, the angle between the tilt direction of the air outlet grille 111 and the width direction of the housing 110 includes 35°, 37°, 39°, 41°, 43°, 44°, 47°, 49°, 51°, 53°, 55°, etc. It should be understood that the above are just examples illustrating the angle between the tilt direction of the air outlet grille 111 and the width direction of the housing 110, and should not be interpreted as a limitation on the angle between the tilt direction of the air outlet grille 111 and the width direction of the housing 110.

[0110] In some possible embodiments, 42°≤α≤48°.

[0111] Therefore, when the angle between the tilt direction of the air outlet grille 111 and the width direction of the casing 110 is between 42° and 48°, the tendency of the airflow direction of the steam guided by the air outlet grille 111 to be parallel to the wall 200 can be further increased, thereby reducing the risk of steam blowing against the wall. At the same time, the angle between the airflow direction of the steam guided by the air outlet grille 111 and the side wall of the casing 110 is increased, further reducing the risk of steam blowing towards the human body.

[0112] For example, the angle between the tilt direction of the air outlet grille 111 and the width direction of the housing 110 can be 42°, 43°, 44°, 45°, 46°, 47°, 48°, etc.

[0113] In some possible embodiments, α = 45°.

[0114] Therefore, when the angle between the tilt direction of the air outlet grille 111 and the width direction of the casing 110 is α = 45°, if the indoor unit 100 of the vertical air conditioner is installed indoors as specified, the steam discharged through the air outlet grille 111 will be parallel to the wall 200. This can prevent the steam from blowing onto the wall and also prevent the steam from blowing onto the human body.

[0115] In some possible embodiments, see Figure 5 , Figure 6 and Figure 7 The air outlet grille 111 includes at least two grille bars 1111, which are spaced apart along the front-rear direction of the housing 110, forming a first air guide 11A; the fresh air outlet 122 of the housing has a first side 112 and a second side 113 along the front-rear direction of the housing 110, and the grille bar 1111 adjacent to the first side 112 is the first grille bar (i.e., the... Figure 5 The first side 112 of the first grid bar forms a second guide port 11B with the first grid bar shown in B1; the second side 113 is located behind the first side 112, and the grid bar 1111 adjacent to the second side 113 is the second grid bar (i.e., the second grid bar). Figure 5 (As shown in B2), a third guide port 11C is formed between the second grid bar and the second side 113; wherein, the area where the first guide port 11A is opposite to the steam outlet 1311 is the second area, and the area where the first guide port 11A is not opposite to the steam outlet 1311, as well as the second guide port 11B and the third guide port 11C, form the first area.

[0116] It should be noted that the front-to-back direction of the housing 110 refers to the direction from front to back or from back to front, i.e. Figure 1 The direction indicated by the X arrow.

[0117] At least two grille bars 1111 are arranged at intervals along the front and rear direction of the casing 110 to form a first guide port 11A, and the steam outlet 1311 is set opposite to the first guide port 11A, thus constructing a directional channel for steam. That is, after the steam is discharged from the steam outlet 1311, it can be directly and quickly discharged through the first guide port 11A, reducing the residence time of steam inside the casing 110. Since fresh air can be discharged from the first guide port 11A, the second guide port 11B and the third guide port 11C, the effect of steam being discharged with fresh air can be guaranteed, thereby reducing the dispersion of steam inside the casing 110, while ensuring the consistency between the steam discharge direction and the fresh air discharge direction.

[0118] In some possible embodiments, see Figure 1 , Figure 2 , Figure 6 and Figure 8 The housing 110 has opposing first sidewalls 114 and second sidewalls 115 along its width direction; the housing fresh air outlet 122 includes a first fresh air outlet 1221 and a second fresh air outlet 1222, the first fresh air outlet 1221 being located on the first sidewall 114; the second fresh air outlet 1222 being located on the second sidewall 115; the steam outlet 1311 includes a first outlet 13111 and a second outlet 13112, the first outlet 13111 being located upstream of and opposite to the first fresh air outlet 1221 along the steam conveying direction, and the second outlet 13112 being located upstream of and opposite to the second fresh air outlet 1222 along the steam conveying direction.

[0119] Since the first fresh air outlet 1221 and the second fresh air outlet 1222 are located on opposite sides of the casing 110 in the width direction, and the first outlet 13111 is located upstream of and opposite to the first fresh air outlet 1221 in the steam conveying direction, and the second outlet 13112 is located upstream of and opposite to the second fresh air outlet 1222 in the steam conveying direction, the steam in the first outlet 13111 can be blown into the room along with the fresh air in the first fresh air outlet 1221, and the steam in the second outlet 13111 can be blown into the room along with the fresh air in the first fresh air outlet 1221. The steam in 3112 can be blown into the room with the fresh air in the second fresh air outlet 1222. And through the setting of the air outlet grille 111, the steam and fresh air passing through the first fresh air outlet 1221 and the second fresh air outlet 1222 can be guided. This can effectively prevent the steam from blowing directly onto the human body, reducing the discomfort or even the risk of burns caused by direct steam blowing. It can also prevent the steam from blowing onto the wall 200, causing the wall 200 to become damp or damaged. It takes into account both safety and practicality, and effectively improves the overall user experience.

[0120] Furthermore, the first fresh air outlet 1221 and the second fresh air outlet 1222 are respectively located on both sides of the width direction of the casing 110, which allows fresh air and steam to be blown into the room from the casing 110 in two directions, improving the uniformity of heat dissipation of fresh air and steam, thereby improving the air quality of the room.

[0121] In some possible embodiments, the distance d between the steam outlet 1311 and the air outlet grille is d. Figure 9 The distance indicated by arrow d is 5mm ≤ d ≤ 30mm.

[0122] If the distance between the steam outlet 1311 and the air outlet grille is less than 5mm, it means that the distance between the steam outlet 1311 and the air outlet grille is too close. This increases the difficulty of setting up the steam outlet 1311 and shortens the heat transfer distance between the heat in the steam and the casing 110. As a result, the heat in the steam can be directly transferred to the casing 110, which can easily cause the fresh air outlet 122 of the casing to get hot and affect the user experience.

[0123] If the distance between the steam outlet 1311 and the air outlet grille is greater than 30mm, it indicates that the distance between the steam outlet 1311 and the air outlet grille is too large. This increases the travel distance of the steam from the steam outlet 1311 to the air outlet grille, causing a large amount of steam to diffuse between the steam outlet 1311 and the air outlet grille. On the one hand, this reduces the amount of steam passing through the air outlet grille, and on the other hand, it increases the risk of condensation forming inside the fresh air outlet 122 of the casing.

[0124] Based on this, the distance between the steam outlet 1311 and the air outlet grille is between 5mm and 30mm. This reduces the difficulty of setting up the steam outlet 1311, avoids the casing fresh air outlet 122 from getting too hot, and ensures the amount of steam passing through the casing fresh air outlet 122, reducing the risk of condensation forming inside the casing fresh air outlet 122.

[0125] For example, the distance between the steam outlet 1311 and the air outlet grille can be 5mm, 6mm, 7mm, 10mm, 12mm, 15mm, 16mm, 20mm, 21mm, 25mm, 30mm, etc.

[0126] In some possible embodiments, napkin Figure 9 and Figure 10 The humidification module 130 also includes a humidifier 132 and a humidification pipe fitting 133. The humidifier 132 is disposed inside the housing 110 and is used to generate steam. The inlet end of the humidification pipe fitting 133 is connected to the humidifier 132, and the outlet end of the humidification pipe fitting 133 is connected to the humidification inlet 131.

[0127] The humidifier 132 heats liquid water to turn it into steam, and the humidification pipe fitting 133 is generally a flexible pipe for easy installation.

[0128] Therefore, by connecting the humidifying pipe component 133 to the humidifier 132 and the humidifying inlet component 131 respectively, on the one hand, it is convenient to introduce the steam in the humidifier 132 into the humidifying inlet component 131. On the other hand, the humidifying pipe component 133 can cause larger water droplets to settle down and be introduced into the humidifier 132 during the process of guiding the steam, thereby reducing the larger water droplets in the steam blown out from the fresh air outlet 122 of the casing and improving the humidification effect of the air conditioner.

[0129] In some possible embodiments, see Figure 11 , Figure 12 and Figure 13 The housing 110 is provided with a fresh air duct 124, which is connected to the fresh air outlet 122 of the housing and the fresh air outlet 1232 of the volute. The humidification inlet 131 includes a first air inlet 1312, a second air inlet 1313, a steam pipe 1314 and a mixed gas pipe 1315. The first air inlet 1312 is connected to the humidification pipe fitting 133. The second air inlet 1313 is connected to the fresh air duct 124. The first end of the steam pipe 1314 is connected to the first air inlet 1312. The first end of the mixed gas pipe 1315 forms a steam outlet 1311. The second end of the mixed gas pipe 1315 is connected to the second air inlet 1313. The second end of the steam pipe 1314 extends into the mixed gas pipe 1315 through the second end of the mixed gas pipe 1315, so that the steam and fresh air in the mixed gas pipe 1315 are both blown out through the steam outlet 1311.

[0130] Therefore, the humidification inlet 131 obtains steam by connecting to the humidification pipe 133 through the first air inlet 1312, and introduces fresh air by connecting to the fresh air duct 124 through the second air inlet 1313. This allows the steam and fresh air to be fully mixed in the mixing pipe 1315, and then blown out through the steam outlet 1311. This reduces the temperature of the steam, thereby avoiding the accumulation of heat at the fresh air outlet 122 of the casing, which could lead to overheating, and also improves the effect of guiding the steam into the room.

[0131] Furthermore, there is no specific limitation on the depth to which the second end of the steam pipe 1314 extends into the mixing gas pipe 1315, as long as the fresh air and steam are fully and evenly mixed in the mixing gas pipe 1315, and the fresh air can dissipate heat from the steam in the mixing gas pipe 1315 to avoid overheating at the fresh air outlet 122 of the casing. Those skilled in the art can design the depth to which the second end of the steam pipe 1314 extends into the mixing gas pipe 1315 according to the steam flow rate and the fresh air flow rate.

[0132] In some possible embodiments, see Figure 12 and Figure 15 The humidification inlet 131 also includes an air guide plate 1316, which is disposed at the second air inlet 1313 and is used to introduce fresh air into the second air inlet 1313.

[0133] Therefore, by setting the air guide plate 1316, the air volume of fresh air introduced into the second air inlet 1313 can be increased, which has a significant effect on reducing the temperature of steam in the mixed gas pipe 1315 and guiding steam through the air outlet grille 111.

[0134] Correspondingly, the larger the area of ​​the air guide plate 1316, the more obvious the airflow guiding effect. Those skilled in the art can design the shape and area of ​​the air guide plate 1316 according to actual needs.

[0135] For example, such as Figure 12 As shown, the air guide plate 1316 is a quadrilateral plate. The air guide plate 1316 is connected to the edge of the second air inlet 1313 away from the outlet of the fresh air duct. The height of the air guide plate 1316 increases along the width direction of the casing 110 and away from the second air inlet 1313, which is conducive to introducing more fresh air into the second air inlet.

[0136] In some possible embodiments, see Figure 14 and Figure 15 The mixed gas duct 1315 includes a bottom wall 13151, which is inclined toward the bottom of the housing 110 from the steam outlet 1311 toward the second air inlet 1313. The edge of the steam outlet 1311 toward the bottom of the housing 110 is flush with the edge of the fresh air outlet 122 of the housing.

[0137] Since the bottom wall 13151 is inclined towards the bottom of the casing 110 from the steam outlet 1311 toward the second air inlet 1313, the condensation formed in the bottom wall 13151 due to the reduction of the temperature in the steam by the fresh air will be deposited on the bottom wall 13151 of the mixed gas pipe 1315, and then introduced from the bottom wall 13151 toward the steam pipe 1314, thus preventing the condensation from flowing out of the casing 110.

[0138] Furthermore, since the edge of the steam outlet 1311 facing the bottom of the casing 110 is flush with the edge of the fresh air outlet 122 of the casing, it can prevent the condensation at the steam outlet 1311 and the fresh air outlet 122 of the casing from flowing into the steam pipe 1314 along the bottom wall 13151 of the mixed gas pipe 1315 and finally being guided into the humidification pipe fitting 133 by the steam pipe 1314, thereby solving the problem of condensation exposure and improving the user experience.

[0139] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
