Example 1

The main body of the present embodiment is a household air supply device, which includes an air supply assembly, please refer to fig. 1 to 3 and fig. 6, a structural schematic diagram of the air supply assembly at different viewing angles and a top schematic diagram of a housing 10, wherein the air supply assembly includes:

the air duct type air conditioner comprises a shell 10, wherein an air duct is arranged in the shell 10, and a window 11 is arranged on the shell;

a rotor 20, the rotor 20 being a hollow housing provided with an inner cavity 22, and an outer peripheral portion 21 thereof defining a ventilation portion and a non-ventilation portion 25, wherein the rotor 20 is rotatably provided in the housing 10 around its axis, and a part of the rotor in a circumferential direction is fitted into the window 11; when the rotating body 20 rotates to the ventilating portion and is partially or completely exposed out of the casing 10, the air duct is communicated with the external space through the inner cavity 22 of the rotating body 20 and the ventilating portion.

The air duct disposed in the housing 10 is mainly used for transmitting the air flow, and the air duct transmits the air flow to the inner cavity 22 of the rotating body 20. At this time, the air flow flows from the inner cavity 22 of the rotor 20 toward the ventilation portion formed on the outer peripheral portion 21 of the rotor 20.

Referring to fig. 2, fig. 2 is a schematic top view of the housing 10, wherein the window 11 and the interior of the housing 10 are connected to each other. Referring to fig. 2 and 7, since a portion of the rotating body 20 in the circumferential direction is inserted into the window 11 formed on the housing 10, the rotating body 20 is separated into an inserted portion and an unengaged portion which are relatively separated from each other by the housing 10. When the ventilation part is fully or partially exposed to the housing 10 through the window 11, the ventilation part and the indoor environment are communicated with each other to realize air supply, and when the ventilation part is not exposed to the housing 10, see fig. 7 and 8, the non-ventilation part 25 blocks the window 11. That is, when the air supply assembly is turned off as desired by the user, the entire rotating body 20 may be directly rotated, so that the non-ventilating portion 25 blocks the window 11. At this time, the air blowing assembly is no longer able to blow air.

In this embodiment, since the rotating body 20 only rotates around its own axis, when the air supply assembly is opened or closed, the occupied space and orientation of the air supply assembly in the housing 10 will not change, thereby effectively avoiding the interference between the air supply assembly and external components such as walls and ceilings when the air supply assembly supplies air, and improving the reliability of the household air supply device and the air supply assembly.

The housing 10 may be a housing constituting the household air supply device as shown in the present embodiment, or may be a housing independent from the household air supply device. For example, in another embodiment, the housing 10 is configured to be independent of the housing of the household air supply apparatus. The present disclosure is not particularly limited thereto.

Further, in the present embodiment, the ventilation portion is divided into a plurality of ventilation areas along the circumferential direction of the outer peripheral portion 21, and the rotation body 20 is configured to be rotated to expose any one of the ventilation areas to the housing 10, and the ventilation areas of the different ventilation areas are different.

When the rotor 20 rotates around its axis, the ventilation areas arranged along the circumferential direction of the outer peripheral portion 21 of the ventilation portion are sequentially exposed to the housing 10 through the window 11, and the ventilation areas are correspondingly communicated with the external space to supply air.

And because the ventilation areas of the ventilation areas are different, the blowing air volume of each ventilation area under the same condition is also different, so that a user can correspondingly select the ventilation area to blow air according to the requirement of the user on the air volume. For example, when a user demands a high air volume, the user can select a ventilation area having a large ventilation area by rotating the rotary body 20, and the ventilation area is exposed to the casing 10 through the window 11 to supply air; when a user demands a low air volume, the user can select a ventilation area having a small ventilation area by rotating the rotor 20, and the ventilation area is exposed to the housing 10 through the window 11 to supply air.

Compared with the related technical scheme, the air supply assembly provided by the embodiment realizes the secondary control of the air supply volume mainly by arranging a plurality of ventilation areas with different respective ventilation areas. In the adjusting process, the operation parameters of the household air supply device do not need to be changed, and the device has the remarkable advantages of convenience in use and simplicity in control.

More specifically, please refer to fig. 4 and 5, and fig. 4 and 5 are schematic structural views of the rotating body from different viewing angles, respectively. It can be seen that, in the present embodiment, the ventilation portion includes a ventilation opening 23 formed in the outer peripheral portion 21 and communicating with the inner cavity 22, and an air guide provided in the ventilation opening 23. Referring to fig. 6, a cross-sectional view of the rotor 20 is shown. In the present embodiment, the ventilation portion including the ventilation opening 23 is divided into the first ventilation area 23a and the second ventilation area 23b which are arranged in a staggered manner in the circumferential direction of the outer peripheral portion 21. The air guide piece is an air guide blade 24, and the density degrees of the air guide blades 24 arranged in different ventilation areas are different, so that the ventilation areas of the different ventilation areas are different.

Referring to fig. 6 again, it can be seen that, in the present embodiment, the first ventilation area 23a and the second ventilation area 23b occupy the same area of the ventilation opening 23 and are arranged along the outer circumferential portion 21 in a staggered manner, and the density of the wind-guiding blades 24 arranged in the two areas is different. The air guide blades 24 provided in the first ventilation area 23a are denser than the air guide blades 24 provided in the second ventilation area 23 b. That is, the number of the air guide blades 24 in the first ventilation area 23a is greater than the number of the air guide blades 24 provided in the second ventilation area 23b, and the pitch between the air guide blades 24 in the first ventilation area 23a is smaller than the pitch between the air guide blades 24 provided in the second ventilation area 23 b. At this time, the ventilation area of the first ventilation area 23a is smaller than that of the second ventilation area 23b due to the covering action of the air guide blades 24, and the first ventilation area 23a is suitable for the case where a small air volume is required, while the second ventilation area 23b is suitable for the case where a large air volume is required.

It should be noted here that in the present embodiment, the coverage area of each air guiding blade 24 with respect to the ventilation opening 23 is the same, specifically, the ventilation areas of different ventilation areas are different by the number of the air guiding blades 24 and the difference in the pitch between the air guiding blades 24. In another embodiment, the distances between the air guide vanes 24 in different ventilation areas are the same, and the coverage area of the air guide vanes 24 in each ventilation area to the ventilation opening 23 is different, so that the ventilation areas of different ventilation areas are different.

It is also to be noted that, in the present embodiment, the above-described first ventilation area 23a and second ventilation area 23b are offset from each other in the circumferential direction of the outer peripheral portion 21, but this does not mean that the respective ventilation areas can achieve the above-described effects only if they are offset from each other in the circumferential direction of the outer peripheral portion 21. The respective ventilation areas may also partially overlap in the circumferential direction of the outer circumferential portion 21. For example, in another embodiment, the ventilation portion is divided along the circumferential surface of the outer circumferential portion 21 into a first ventilation area 23a and a second ventilation area 23b that partially overlap in the circumferential direction of the outer circumferential portion 21. When the entire rotating body 20 is rotated, a part of the ventilation opening 23 communicates with the indoor environment both when the first ventilation area 23a is exposed to the housing 10 through the window 11 and when the second ventilation area 23b is exposed to the housing 10 through the window 11, that is, the first ventilation area 23a and the second ventilation area 23b share a part of the ventilation opening 23. This arrangement can divide the entire ventilation portion into a larger number of functional regions, thereby improving the utilization efficiency of the area on the outer peripheral portion 21.

The air guide provided in the vent 23 is mainly used to guide the air flow, and may be any air guide such as a grill or an air guide bar. The implementation personnel can realize the purpose of different ventilation areas of the ventilation parts by correspondingly adjusting the arrangement forms of the air guide pieces. For example, in another embodiment, the air guide is a grille, and the grille meshes in different ventilation areas are different in size, so that the ventilation areas in the respective ventilation areas are different.

It should be noted that in the present embodiment, the ventilation portion includes only one ventilation opening 23, but this does not mean that the ventilation area must be divided into the same ventilation opening 23. Meanwhile, the implementer can adopt specific means for realizing different ventilation areas according to the specific type of the ventilation part. For example, in another embodiment, the ventilation part is a plurality of air holes formed on the outer peripheral portion 21, and the air holes of different ventilation areas are arranged densely and/or have different hole diameters, so that the ventilation areas of the respective ventilation areas are different.

The household air supply device can be an air conditioner indoor unit 30, an air purifier or a fan, and it can be understood that the household air supply device is provided with an air inlet 31 for realizing the basic air supply function. In this embodiment, the household air supply device further comprises a fresh air channel for introducing outdoor fresh air, and the fresh air channel forms the air duct. That is to say, the air supply assembly that this embodiment provided is used for realizing the new trend air supply. Meanwhile, in the present embodiment, the air inlet 31 of the household air supply device is disposed on the housing 10 and outside the window 11, and the ventilation portion is configured to guide the fresh air to move toward a side close to the air inlet 31.

Through the setting to the ventilation part, can guide the new trend air supply effectively, make the new trend roughly move towards predetermineeing the expectation direction. In this embodiment, window 11 outside is located to domestic air supply arrangement's air intake 31, and ventilation unit guide new trend is towards being close to air intake 31 one side and is removed for the new trend can be caught by the negative pressure of air intake 31 department more easily, lets more new trends participate in to domestic air supply arrangement's air supply in the middle of, makes the new trend cover whole indoor space rapidly, promotes the user's impression under the new trend mode.

Meanwhile, because the temperature of the fresh air in the outdoor environment is different from the temperature in the indoor environment to a certain extent, the fresh air is easy to form condensation on the wall surface of the indoor wall after being blown out. Fresh air in the outdoor environment is directly blown to the human body, and the body feeling of the human body is also influenced. And in this embodiment, through leading the new trend, can effectively avoid the new trend to blow directly in human body or wall, and then effectively improve the travelling comfort of new trend air supply.

In the present embodiment, when the ventilation opening 23 is exposed to the housing 10, the plurality of air guide vanes 24 in the ventilation opening 23 are sequentially arranged at intervals from the direction close to the air inlet 31 to the direction away from the air inlet 31, and the air guide vanes 24 extend toward the side close to the air inlet 31 in the air blowing direction of the ventilation opening 23.

Referring to fig. 6, the air guide blade 24 is extended toward the air inlet 31. Referring to fig. 7 and 8, the blown air flow adheres to the surface of the wind guide vane 24 and flows along the extending direction of the surface of the wind guide vane 24, so as to flow toward the side close to the air inlet 31, and is guided to the air inlet 31. It should be noted that the extension of the air guiding blade 24 toward the side close to the air inlet 31 may be in a straight line form, i.e., a straight inclined extension, or may be in a slightly curved form as shown in the present embodiment, which is not limited by the present disclosure.

The implementer can correspondingly adjust the specific form of the air guide according to the self requirement. For example, in another embodiment, the air guide is a grille covering the air vent 23, wherein the mesh size of the grille on the side close to the air inlet 31 is larger than the mesh size of the grille on the side far from the air inlet 31, thereby promoting the fresh air to have a tendency to move toward the air inlet 31.

Further, the specification is required. The central angle of the outer peripheral portion 21 occupied by the non-ventilation portion 25 may be greater than or equal to the central angle of the portion of the rotating body 20 embedded in the window 11, to achieve the sealing of the window 11 by the non-ventilation portion 25. In addition, in the present embodiment, the first ventilation area 23a, the second ventilation area 23b, and the non-ventilation portion 25 each occupy a central angle of 120 ° of the outer peripheral portion 21.

Further, the implementer may specifically select the specific number of the ventilation areas described in the foregoing according to his own needs, for example, three ventilation areas may be used, or five ventilation areas may be used, which is not limited by the present disclosure. The rotating body 20 is partially embedded in the window 11, and the rotating body 20 is divided into an embedded part and a non-embedded part which are relatively separated by the shell 10, wherein the embedded part realizes the preset basic function, such as air supply or blocking in a specific direction. Therefore, in the present embodiment, the diameter of the outer peripheral portion 21 is D, and a projection of a portion of the rotating body 20 fitted into the window 11 on a cross section perpendicular to the axial direction of the rotating body 20 is a first arch whose arch height is not greater than D/2. Set up like this and to make whole rotor 20 under the prerequisite of the same size, the ventilation portion can divide more ventilation region, lets rotor 20 can realize multiple functions, simultaneously, sets up like this and can also ensure the installation stability of whole rotor 20 within casing 10, avoids rotor 20 to deviate from in the middle of its rotation process.

The inner chamber 22 of the rotor 20 is primarily intended to communicate with the outlet end of the air duct. Referring to fig. 5, in the present embodiment, an inner cavity inlet 26 communicated with the air duct is formed at one axial end of the rotating body 20, the inner cavity inlet 26 is configured in a through hole shape coaxially disposed with the rotating body 20, and the inner cavity inlet 26 is abutted to the outlet end of the air duct. The arrangement can ensure that the inner cavity inlet 26 and the air duct outlet end are always kept in a communicated state in the rotating process of the whole rotating body 20, and continuous communication between the rotating body 20 in a moving state and the air duct outlet end in a static state is realized.

In another embodiment, a rotary joint is provided between the outlet end of the air duct and the rotator 20, one end of the rotary joint is communicated with the outlet end of the air duct, and the other end is communicated with the inner cavity 22. In the embodiment, the rotary joint is added, so that the assembly precision and the product manufacturing cost are improved.

The manually rotatable rotor 20 is more suitable for household air supply devices with low arrangement positions, such as floor cabinets, fans, air purifiers and the like.

In the present embodiment, the driving mechanism is provided in the housing 10, and the driving mechanism includes a roller in rolling contact with the outer peripheral portion 21, and a driving motor for driving the roller to rotate. The driving motor is connected with the roller through a speed reduction pair to ensure the motion precision of the rotating body 20 under the action of the driving mechanism.

In the present embodiment, the casing 10 is further provided with an observation window, one end portion of the rotating body 20 extends to the observation window, and the end surface of the rotating body 20 extending to the observation window is connected with the display 27. The display screen 27 may be used to display various parameters associated with the indoor air environment, but is not limited by the present disclosure.
