The invention provides a ceiling machine which can be a ceiling machine or an embedded air conditioner. The ceiling can adjust the opening of the air outlet along the radial direction of the air outlet.

Referring to fig. 1 to 3, in an embodiment of a ceiling fan according to the present invention, the ceiling fan includes a housing, a flexible air guide ring 100, and a driving device 200; the shell comprises a panel assembly, wherein the panel assembly is provided with an air inlet with a downward opening and an air outlet annularly arranged at the periphery of the air inlet; the flexible air guide ring 100 is slidably mounted on the upper surface of the panel assembly, so that the flexible air guide ring 100 radially expands or contracts to adjust the opening of the air outlet; the driving device 200 is mounted on the housing and connected to the flexible wind-guiding ring 100 to drive the flexible wind-guiding ring 100 to expand or contract in a radial direction.

Specifically, the casing further includes a cylindrical casing 10, and the lower end of the casing 10 has a downward opening, and the casing 10 is formed with a receiving cavity for mounting the wind wheel device 80 and the heat exchanger 90 of the ceiling fan, and an air supply channel communicating the air inlet and the air outlet on the inner side of the casing 10.

The panel assembly is disposed at the open end of the housing 10, the air inlet is formed in the middle region of the panel assembly, and the shape of the air inlet may be varied, for example, circular, elliptical, ring-shaped, square or polygonal, etc., without being limited thereto. The air outlet is annularly arranged at the periphery of the air inlet, so that the ceiling machine can concentrate air inlet from the middle area of the panel assembly and can discharge air from the circumferential side of the panel assembly to form a larger air outlet area.

The display assembly 40 of the ceiling fan is mounted on the lower surface of the panel assembly, and the display assembly 40 is used for displaying air conditioning functions, operation parameters and the like. The display assembly 40 may be disposed in a central area of the panel assembly or in a peripheral area of the air outlet, which is not particularly limited herein.

The flexible air guide ring 100 is provided on the inner side of the housing 10 and is slidably connected to the panel assembly. The flexible air guide ring 100 is made of a flexible material, so that the flexible air guide ring 100 has better softness and elasticity, and the flexible air guide ring 100 is driven to expand or contract along the radial direction of the air outlet by using the characteristic of flexible deformation of the flexible air guide ring 100 through the driving device 200, so that the coverage area of the flexible air guide ring 100 covered at the air outlet position is changed, namely the opening degree of the air outlet is changed.

It should be noted that the radial direction of the air outlet should be the radial direction of the air outlet inner ring 61.

The flexible material may be flexible plastic or rubber, or other resilient material. The flexible air guiding ring 100 should be deformable along the ring Zhou Shensu thereof, so that the flexible air guiding ring 100 can be better stretched along the radial direction of the air outlet.

According to the technical scheme, the panel assembly of the ceiling machine is provided with the annular air outlet and the flexible air guide ring 100 which is slidably arranged on the panel assembly, so that the flexible air guide ring 100 is driven by the driving device 200 to radially expand or contract along the air outlet by utilizing the softness and elasticity of the flexible air guide ring 100, the coverage area of the flexible air guide ring, which covers the air outlet, is changed, and the opening degree of the air outlet is adjusted, so that the adjustable air outlet volume is realized. For example, when the flexible air guide ring 100 slides along the radial direction away from the air outlet, the flexible air guide ring 100 contracts, the coverage area of the flexible air guide ring 100 covered on the air outlet decreases, the opening degree of the air outlet increases, the air outlet volume increases, and the air outlet range increases; when the flexible air guide ring 100 slides along the radial direction near the air outlet, the flexible air guide ring 100 expands, the coverage surface of the flexible air guide ring 100 covered on the air outlet increases, the opening degree of the air outlet decreases, namely the air outlet angle correspondingly decreases, the air outlet quantity decreases, and the air outlet range also decreases. Therefore, compared with the existing air deflector which is rotatably arranged at the air outlet, the ceiling machine can realize adjustable air outlet air quantity.

Referring to fig. 3 and 4, in this embodiment, to facilitate installation of the flexible air guide ring 100, the panel assembly includes a panel 20 and an installation frame 60 disposed above the panel 20 and having a ring shape, and the flexible air guide ring 100 is installed on the installation frame 60.

The air inlet grille 30 may be integrally or separately provided with the panel 20.

The panel assembly further comprises a fixing frame 70 arranged in the shell 10, and the mounting frame 60 is arranged between the panel 20 and the fixing frame 70 and is detachably connected with the fixing frame 70. The fixing frame 70 and the mounting frame 60 define a space for the flexible wind guide ring 100 to expand or contract in a radial direction.

Referring to fig. 5 to 6, the mounting frame 60 includes an inner ring 61, an outer ring 62, and a plurality of connecting rods 63 connecting the inner ring 61 and the outer ring 62, an air passage communicating with the air outlet is defined between the outer ring 62 and the inner ring 61, and the flexible air guide ring 100 is mounted above the air passage. The inner ring 61 is in screw connection with the inner edge of the fixing frame 70, and the inner periphery of the inner ring 61 is provided with an upwardly extending air guide wall which is used for guiding the air flow entering from the air inlet to the direction of the wind wheel device 80; the outer ring 62 and the fixing frame 70 can be connected by adopting a hook or a buckle and other structures.

When the ceiling machine works, the wind wheel device 80 drives air flow to enter the air supply channel from the air inlet through the air inlet grille 30, then exchanges heat through the heat exchanger 90 to form air outlet air flow, and the air outlet air flow is blown to the air outlet along the air supply channel and finally is led out through the fan blade rotating wheel 50.

To stably support the arc-shaped wind guide section 110 using the slider 130, it is preferable that the slider 130 is provided at an end of the arc-shaped wind guide section 110.

Referring to fig. 7 and 8, in the present embodiment, the sliding block 130 and the sliding slot 64 are considered to have a larger resistance, so that the sliding block is not easy to slide, or noise is easily generated during the sliding process. In this embodiment, the balls 140 are embedded in the lower end surface of the slider 130.

Specifically, the sliding groove 64 is disposed on the connecting rod 63 of the mounting frame 60, and in the process of the flexible air guiding ring 100 extending and contracting in the radial direction, the balls 140 roll on the bottom groove wall of the sliding groove 64, so that the friction resistance between the sliding block 130 and the bottom groove wall of the sliding groove 64 can be reduced, and the sliding of the flexible air guiding ring 100 is smoother.

Referring to fig. 7 and 8, the lower end of the slider 130 is preferably further provided with a roller 150 positioned on the upper side of the ball 140. In order to contact the roller 150 with the side wall of the chute 64 during the radial expansion and contraction of the flexible air guiding ring 100, the frictional resistance between the slider 130 and the side wall of the chute 64 is reduced, and the flexible air guiding ring 100 slides smoothly.

The driving device 200 is structured in various ways, and the following two ways are exemplified here:

referring to fig. 9, mode one: the driving device 200 includes a motor 210, a gear 21b and a rack 22b, the gear 21b is connected with the motor 210, the rack 22b extends in a long strip shape along a radial direction, one end of the rack 22b is meshed with the gear 21b, and the other end of the rack 22b is connected and fixed with the flexible wind guiding ring 100. In this way, the motor 210 drives the gear 21b to rotate, so as to drive the rack 22b to move along the radial direction, thereby driving the flexible air deflector to expand or contract along the radial direction.

Referring to fig. 10, the second method is: the driving device 200 includes a motor 210, a first connecting rod 21a and a second connecting rod 22a, wherein one end of the first connecting rod 21a is pivoted to the motor 210, the other end of the first connecting rod 21a is pivoted to or hinged to one end of the second connecting rod 22a, and the other end of the second connecting rod 22a is fixedly connected to the flexible wind guiding ring 100. In this way, the motor 210 drives the first connecting rod 21a to swing, and drives one end of the second connecting rod 22a to move along the radial direction, so as to drive the flexible air deflector to expand or contract along the radial direction.

Referring to fig. 7, in the present embodiment, the flexible air guiding ring 100 may be integrally formed or separately formed. In order to facilitate controlling the expansion and contraction of the flexible air guide ring 100, the flexible air guide ring 100 adopts a split arrangement.

Preferably, the flexible wind guiding ring 100 comprises a plurality of arc-shaped wind guiding sections 110 which are spliced in sequence along the same circumference. Specifically, the ceiling fan is provided with a driving device 200 corresponding to each arc-shaped air guide section 110, and the plurality of arc-shaped air guide sections 110 are synchronously driven to stretch along the radial direction by the plurality of driving devices 200, so that the air outlet surface of the air outlet can be ensured to be concentric rings, and the uniform air outlet effect is achieved; or each driving device 200 independently drives an arc-shaped air guiding section 110 to radially stretch along the air outlet, so as to achieve the effect of independently controlling the air outlet area of the air outlet.

As for the number of the arc-shaped air guiding sections 110, for example, 3 or 4, the number of the arc-shaped air guiding sections 110 may be adaptively designed according to the size of the air outlet. Preferably, the number of the air outlets is 4.

Further, as shown in fig. 7, in order to make the air outlet uniform, the central angles corresponding to any two arc-shaped air guiding sections 110 are equal in size. By the arrangement, when the plurality of driving devices 200 synchronously drive the arc-shaped air guide sections 110 to stretch, the stretching deformation quantity of the arc-shaped air guide sections 110 is approximately equal, so that all air outlet surfaces of the air outlet are ensured to be concentric and annular all the time, and uniform air outlet effect is achieved.

In this embodiment, the flexible wind guiding ring 100 may have various structural arrangements, and is not particularly limited. In order to provide the flexible wind-guiding ring 100 with better elasticity, it is preferable that the flexible wind-guiding ring 100 is formed of a plurality of expansion fold rings which are sequentially folded along the same circumference.

This kind of setting method, can be when flexible wind-guiding ring 100 deformation, with the deformation volume along flexible wind-guiding ring 100's periphery dispersion to each flexible pleat ring for flexible wind-guiding ring 100's inner edge and outer fringe have different deformation volume, thereby ensure no matter flexible wind-guiding ring 100 expands or contracts to the position, the air-out face of air outlet all can keep being concentric ring shape, and then reaches the air-out is indiscriminate in each angle of air outlet, improves user's comfort.

Referring to fig. 10 to 12, in the present embodiment, a diversion trench 120 is formed between two adjacent telescopic pleat rings, and the diversion trench 120 is V-shaped. Specifically, the flexible air guiding ring 100 forms a guiding groove 120 between every two adjacent telescopic pleat rings, and the plurality of guiding grooves 120 are sequentially arranged at intervals along the circumference of the flexible air guiding ring 100.

In this arrangement, on the one hand, when the air-out airflow passes through the periphery of the flexible air deflector, the plurality of diversion trenches 120 comb the air-out airflow into a plurality of smaller airflows, so that the air-out airflow is diffused downwards more gently, and discomfort symptoms such as dizziness or cold and the like caused by over strong wind sense are avoided; on the other hand, the diversion trenches 120 have two connected diversion surfaces, and the diversion surfaces of the plurality of diversion trenches 120 correspondingly increase the air guiding surface of the flexible air guiding ring 100, so as to effectively balance the temperature difference between the upper surface and the lower surface of the flexible air guiding ring 100, thereby reducing the generation of condensed water.

Preferably, the included angle formed between two adjacent diversion surfaces of the diversion trench 120 ranges from 30 ° to 120 °, such as 40 °, 55 °, 75 °, 95 ° or 115 °. If α is smaller than 30 °, an included angle formed between two connected diversion surfaces of the diversion trench 120 is too small, the resistance of the diversion trench 120 to the air-out airflow is large, and the air-out airflow is not easy to pass through the diversion trench 120; if α is greater than 120 °, an included angle formed between two connected diversion surfaces of the diversion trench 120 is too large, the resistance of the diversion trench 120 to the air-out airflow is small, and the air-out airflow passes through the diversion trench 120 rapidly, so that the combing effect of the diversion trench 120 on the air-out airflow is not obvious. Therefore, the included angle between two adjacent diversion surfaces of the diversion trench 120 is limited to 30-120 degrees.

Of course, in other embodiments, the flexible air guide ring 100 may be provided in other arrangements. For example, the flexible air guiding ring 100 is formed by a plurality of arc-shaped sleeves which are sequentially and slidably sleeved along the same ring Zhou Shouwei, when the flexible air guiding ring 100 is far away from the air outlet in the radial direction, each arc-shaped sleeve is contracted towards the other arc-shaped sleeve sleeved with the other arc-shaped sleeve and is at least partially accommodated in the arc-shaped sleeve, so that the flexible air guiding ring 100 is contracted inwards; when the flexible air guiding ring 100 approaches the air outlet in the radial direction, each arc sleeve extends out from the other arc sleeve sleeved with the arc sleeve, so that the flexible air guiding ring 100 expands outwards.

Specifically, each arc-shaped sleeve is made of flexible materials, the head part of each arc-shaped sleeve is larger than the tail part of each arc-shaped sleeve, and the head part of each arc-shaped sleeve is sleeved on the tail part of another adjacent arc-shaped sleeve in a sliding manner; because the arc sleeve is made of flexible materials, the sleeve mouth of the arc sleeve can be deformed in a telescopic way, so that the flexible air guide ring 100 is ensured to be more compact than the sleeving position in the telescopic process.

Based on any of the above embodiments, in order to increase the air outlet range of the air outlet, the outer edge of the upper surface of the flexible air guiding ring 100 is provided with a chamfer, and the chamfer may be a rounded corner or a unfilled corner, so that the outer edge of the upper surface of the flexible air guiding ring 100 forms a guiding inclined plane. When the air-out airflow blows to the air outlet from top to bottom, the air-out airflow is spread out along the diversion slope of the flexible air guide ring 100, so that the air-out range of the air-out airflow is enlarged on one hand; on the other hand, the uncomfortable symptoms such as dizziness or cold and the like caused by the fact that the air-out airflow is directly blown downwards to the user are avoided.

In this embodiment, in order to enhance the elasticity of the flexible air guiding ring 100, so that the flexible air guiding ring 100 can be reset in time, the flexible air guiding ring 100 is hollow, a cavity is formed inside the flexible air guiding ring 100, and the flexible air guiding ring 100 further includes an elastic reset member disposed in the cavity.

The elastic restoring piece is preferably good in elasticity, and the elastic restoring piece can be a spring, a rubber band or an elastic belt. If the flexible air guide ring 100 is integrally formed, the elastic restoring member is annularly arranged and annularly arranged in the cavity; if the flexible air guide ring 100 is separately arranged and is composed of a plurality of arc-shaped air guide sections 110 which are spliced in sequence along the first position of the same circumference, the elastic resetting piece is arranged in the cavity of the arc-shaped air guide section 110 in a strip shape, and two ends of the elastic resetting piece are respectively connected with two ends of the arc-shaped air guide section 110. In the above two setting manners, the elastic restoring member can assist the expansion or contraction of the flexible air guiding ring 100, so as to enhance the elasticity of the flexible air guiding ring 100 and prolong the service life of the flexible air guiding ring 100.

In order to avoid forming condensed water on the flexible air guide ring 100, the flexible air guide ring 100 may be hollow, and a heat insulation material is disposed inside the flexible air guide ring 100. The heat insulation material is filled in the air guide ring, and the heat insulation material can be heat insulation cotton or heat insulation foam.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
