[0032] As shown in Figures 1 to 5 , the present embodiment provides a humidifying device 10, which includes a humidifying tank 100 and an atomizing assembly 200. The inside of the humidifying tank 100 is used to store water, and has an outlet portion 110 for outputting humidifying fluid. The atomizing assembly 200 is arranged in the humidifying tank 100, and is used to float on the water surface of the humidifying tank 100 by virtue of the buoyancy of water in the humidifying tank 100, and to form humidifying fluid from the water in the humidifying tank 100.

[0033] In the present embodiment, the humidifying device 10 is applied in an air conditioner indoor unit 1, and the type of the air conditioner indoor unit 1 is not limited, and can be selected as needed.

[0037] In the present embodiment, the specific components included in the atomizing assembly 200 are not limited and can be selected as desired. The atomizing assembly 200 can float on the water surface of the humidifying tank 100 by the buoyancy of the water inside the humidifying tank 100, and can form the humidifying fluid from the water inside the humidifying tank 100. As a specific embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the atomizing assembly 200 includes a support portion 210, a humidifying fluid generator 220 and a water delivery structure 230. It is obvious that this is only exemplary and not the only one.

[0038] In summary, the humidifying device 10 includes the humidifying tank 100 and the atomizing assembly 200, and the atomizing assembly 200 floats on the water surface by the buoyancy and forms the humidifying fluid from the water inside the humidifying tank 100. Such a humidifying device 10 is simple and compact in structure, easy to control and occupies a small volume. Since the air conditioner indoor unit 1 is provided with the humidifying device 10, the indoor humidity can be improved in time, the comfort of people is improved, and the aggravation of some diseases is avoided.

[0039] In some other embodiments, as shown in Figure 1 and Figure 2 , the humidifying device 10 further includes a fan 500, which is arranged on the humidifying tank 100 and opposite to the outlet portion 110 to output the humidifying fluid inside the humidifying tank 100 from the outlet portion 110.

[0040] The fan 500 is opposite to the outlet portion 110, that is, as shown in Figure 1 andFigure 2 As shown in FIG. 1, the outlet portion 110 is located at the front side of the humidifying tank 100, and the fan 500 is located at the rear side of the humidifying tank 100. If the outlet portion 110 is located at the right side of the humidifying tank 100, the fan 500 is located at the left side of the humidifying tank 100, and so on.

[0041] In some other embodiments, the atomization assembly 200 comprises a support portion 210 and a humidifying fluid generator 220. The support portion 210 is arranged in the humidifying tank 100 to float on the water surface of the humidifying tank 100 by the buoyancy of the water in the humidifying tank 100. The humidifying fluid generator 220 is arranged in the support portion 210 to float on the water surface of the humidifying tank 100 to form the humidifying fluid from the water in the humidifying tank 100.

[0042] In the present embodiment, the shape of the support portion 210 is not limited and can be selected as required. For example, the support portion 210 can be flat, cylindrical or other irregular shapes. As a specific embodiment, as shown in FIGS. 2, 3 and 4, the shape of the support portion 210 is hemispherical. Figure 1 、 Figure 2 and Figure 4 As shown in FIGS. 2, 3 and 4, the shape of the support portion 210 is hemispherical.

[0043] In the present embodiment, the arrangement position of the humidifying fluid generator 220 is not limited and can be selected as required. For example, the humidifying fluid generator 220 can be arranged at the edge or middle position of the support portion 210, and so on. As a specific embodiment, as shown in FIGS. 2, 3 and 4, the humidifying fluid generator 220 is arranged at the middle of the support portion 210. Figure 1 、 Figure 2 and Figure 4 As shown in FIGS. 2, 3 and 4, the humidifying fluid generator 220 is arranged at the middle of the support portion 210.

[0044] In the present embodiment, the forming method of the humidifying fluid by the humidifying fluid generator 220 is not limited and can be selected as required. For example, the humidifying fluid generator 220 forms the humidifying fluid by ultrasonic method, or the humidifying fluid generator 220 forms the humidifying fluid by heating method.

[0045] In the present embodiment, the atomization assembly 200 comprises the support portion 210 and the humidifying fluid generator 220, which makes the atomization assembly 200 float on the water surface and form the humidifying fluid from the water. The structure of the atomization assembly 200 is simple and compact.

[0046] In some other embodiments, the inside of the support portion 210 forms a cavity 211, the bottom of which is provided with a mounting through hole 212 for embedding the humidifying fluid generator 220 in the mounting through hole 212, and the upper end of which has an opening portion 213 for discharging the humidifying fluid in the cavity 211.

[0047] In the present embodiment, the shape of the support portion 210 and the shape of the cavity 211 are not limited and can be selected as desired. For example, the shape of the support portion 210 and the shape of the cavity 211 can be a cuboid shape, a cylindrical shape, or another irregular shape. As a specific example, as shown in Figure 1 , Figure 2 and Figure 4 indicate, the shape of the support portion 210 and the shape of the cavity 211 are hemispherical.

[0048] In the present embodiment, the shape of the mounting through-hole 212 is not limited and can be selected as desired. As a specific example, as shown in Figure 4 , the shape of the mounting through-hole 212 is circular. The humidification fluid generator 220 is embedded in the mounting through-hole 212, which causes the bottom surface of the humidification fluid generator 220 to be in contact with the water in the humidification tank 100, while the humidification fluid generated by the humidification fluid generator 220 flows out of the cavity 211, avoiding the humidification fluid from mixing with the water inside the humidification tank 100.

[0049] In the present embodiment, the shape of the opening portion 213 is not limited and can be selected as desired. For example, the opening portion 213 can include one opening or multiple openings. The shape of the opening portion 213 can be circular, square, or another irregular shape. As a specific example, as shown in Figure 4 , the opening portion 213 includes one circular opening, and the plane on which the opening is located passes through the center of the sphere of the support portion 210. This facilitates the humidification fluid to flow out of the cavity 211.

[0050] In other embodiments, the shape of the humidification fluid generator 220 is adapted to the shape of the mounting through-hole 212 to seal the mounting through-hole 212. That is, if the shape of the mounting through-hole 212 is circular, the shape of the humidification fluid generator 220 is also circular, and the size of the mounting through-hole 212 and the size of the humidification fluid generator 220 are adapted.

[0051] In other embodiments, the shape of the support portion 210 is spherical, and the plane on which the opening portion 213 is located passes through the center of the sphere of the support portion 210 to make the shape of the support portion 210 hemispherical. As a specific example, as shown in Figure 4 , the opening portion 213 includes one circular opening, and the plane on which the opening is located passes through the center of the sphere of the support portion 210. This facilitates the humidification fluid to flow out of the cavity 211.

[0052] In some other embodiments, the humidification device 10 further includes a motion guide post 300. The motion guide post 300 is disposed on the bottom side wall of the humidification chamber 100 and extends upward in a direction perpendicular to the bottom side wall; it is configured to allow the atomizing assembly 200 to move along the motion guide post 300 in a direction perpendicular to the bottom side wall under the buoyancy of the water in the humidification chamber 100.

[0053] In this embodiment, the shape of the motion guide post 300 is not limited and can be selected as needed. For example, the motion guide post 300 can be a solid post or a hollow post. For example, the motion guide post 300 can be cylindrical or other shapes. In this embodiment, the atomizing component 200 moves along the motion guide post 300 as it moves up and down with the liquid surface under the action of buoyancy. In this embodiment, the manner in which the atomizing component 200 moves along the motion guide post 300 is not limited. For example, the motion guide post 300 passes through the support portion 210 to allow the atomizing component 200 to move along the motion guide post 300. For example, the motion guide post 300 is disposed at the edge of the support portion 210 to allow the support portion 210 to move along the motion guide post 300. For example, the shape of the motion guide post 300 is cylindrical, and the support portion 210 is disposed inside the motion guide post 300 to move along the motion guide post 300.

[0054] This prevents the atomizing component 200 from floating erratically on the liquid surface, thus avoiding affecting the water filling of the humidification box 100, and also prevents the humidification fluid from being affected by an unstable formation position, which could affect the outflow of the humidification fluid.

[0055] In some other embodiments, the motion guide post 300 includes a first shell 310 and a second shell 320. The first shell 310 is disposed on the bottom sidewall of the humidification chamber 100 and extends upward in a direction perpendicular to the bottom sidewall. The second shell 320 is disposed on the bottom sidewall of the humidification chamber 100 and extends upward in a direction perpendicular to the bottom sidewall, spaced apart from the first shell 310 and forming a cylindrical motion guide post 300 between them. That is, in this embodiment, the motion guide post 300 is a hollow post, and the middle part of the motion guide post 300 is empty. In this embodiment, the shape of the motion guide post 300 is cylindrical, and the shape of the motion guide post 300 can be a cylinder or a square tube, etc.

[0056] like Figure 4 As shown, the support portion 210 is disposed inside the cylindrical motion guide post 300, and its outer periphery abuts against the first column shell 310 and the second column shell 320 respectively to move upward along the cylindrical motion guide post 300 in a direction perpendicular to the bottom sidewall. This makes the up-and-down movement of the support portion 210 more stable.

[0057] In some other embodiments, the first column shell 310 is shaped as a semi-cylinder, the second column shell 320 is shaped as an arc-shaped long strip, and the first column shell 310 and the second column shell 320 are oppositely arranged to define a cylindrical-shaped movement guide column 300, which is shaped to match the shape of the outer periphery of the support portion 210 so that the outer periphery of the support portion 210 respectively abuts against the first column shell 310 and the second column shell 320. As shown in FIG. 6, the movement guide column 300 is shaped as a cylinder, and the support portion 210 is shaped as a hemisphere, which makes the outer periphery of the support portion 210 respectively abut against the movement guide column 300, so that the support portion 210 is subjected to a smaller resistance. Figure 4

[0058] In some other embodiments, the atomization assembly 200 further comprises a water delivery structure 230. The water delivery structure 230 is arranged below the humidification fluid generator 220 and is used to suck water in the humidification tank 100 into the humidification fluid generator 220. In the present embodiment, the material of the water delivery structure 230 is not limited and can be selected as needed. For example, the water delivery structure 230 is a cotton swab.

[0059] In some other embodiments, the humidification device 10 further comprises a water level sensor 400 arranged in the humidification tank 100. The water level sensor 400 is used to detect the water level of the water in the humidification tank 100. The humidification device 10 is configured to stop humidification and prompt water addition when the water level of the water in the humidification tank 100 is lower than a first preset value. The humidification device 10 is configured to start humidification when the water level of the water in the humidification tank 100 is higher than the first preset value and the indoor humidity is lower than a second preset value. The humidification device 10 is configured to stop humidification when the indoor humidity is greater than a third preset value. Alternatively, the humidification device 10 is configured to stop humidification when a stop humidification signal is received, and if no stop humidification signal is received, the indoor humidity is greater than a fourth preset value, a voice prompt is given for the current humidity, and humidification is stopped for a preset period of time until a humidification signal is received again. The fourth preset value is greater than the third preset value, which is greater than the second preset value.

[0060] In some other embodiments, the humidification tank 100 has a water inlet 120 for adding water into the humidification tank 100. The water inlet 120 is close to the first column shell 310 and is located outside the cylindrical-shaped movement guide column 300, which avoids adding water to the atomization assembly 200.
