Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a flow guide device and a heater having the same. Background Art

[0002] Existing bathroom ceiling heaters feature a circular guide structure that delivers warm air 360°. This ring-shaped structure at the air outlet works in conjunction with a mixing cavity to expand the air distribution range and improve air uniformity, thereby enhancing bathing comfort. The claimed 360° warm air delivery primarily refers to the ring structure's ability to deliver air in a 360° circumference.

[0003] Although the circular guide structure can even out the wind speed to a certain extent, due to the limited outlet area and the fact that the annular PTC heater is mostly set at the outlet, the diffusion distance between it and the corresponding outlet is short. The gas heated by the PTC heater has no time to turn or diffuse, and will form an annular curtain-like airflow along the vertical direction or at a certain small angle to the vertical direction, which cannot achieve a true 360° diffusion effect without dead ends.

[0029] 2. The air guide device provided by the present invention comprises an air guide shell including an arc-shaped windward air guide portion and an arc-shaped leeward air guide portion, the windward air guide portion is arranged close to the corner drive mechanism, and the leeward air guide portion is arranged away from the corner drive mechanism, and the two are connected into one by a transition of a smooth curved surface converging toward the center of the air guide shell, and the curvature of the windward air guide portion is greater than the curvature of the leeward air guide portion; the windward air guide portion is arranged close to the corner drive mechanism and is a curved surface with a larger curvature, which mainly serves to evenly distribute the airflow in all directions and guide the airflow to the leeward air guide portion through the wall covering effect; the curvature of the leeward air guide portion is smaller than that of the windward air guide portion, and the two are connected into one by a transition of a smooth curved surface converging toward the center of the air guide shell, and the airflow flows to the leeward air guide portion through the transition curved surface, so that the airflow converges toward the center to form a high-speed air flow column, which can effectively extend the airflow blowing distance.

[0030] 3. The air guide device provided by the present invention also includes a guide cover, which has a first accommodating space, an air inlet and an air outlet. The air inlet is arranged toward the corner driving mechanism, and the air outlet is arranged away from the corner driving mechanism.

The guide cover can converge the airflow to the guide shell arranged in the first accommodating space, and a guide flow channel is formed between the two that first expands outwards to the surroundings and then converges to the center, which can accelerate the flow of airflow and accelerate the formation of high-speed airflow converging to the center at the air outlet, more effectively enhancing the airflow convergence effect, so that the airflow can be blown to a farther distance.

[0031] 4. The heater provided by the present invention includes a main body with an air supply mechanism, and the air outlet of the main body is provided with the above-mentioned guide device. The air supply mechanism includes a fan, a guide plate and a guide plate.

[0032] 5. The heater provided by the present invention has two sets of air supply mechanisms symmetrically arranged along the center of the guide shell. The two sets of air supply mechanisms form a dual-parallel fan system.

[0036] The PTC heater is arranged in the air duct between the air outlet of the guide air duct and the guide housing, so that the air flow has a longer diffusion section after being heated by the PTC heater.

[0037] 7. The heater provided by the present invention includes a main body which further includes a cover plate and a panel. The cover plate is arranged on the side of the wind collecting plate away from the fan, and is provided with a mounting opening which cooperates with the outer peripheral edge of the air deflector; the air inlet of the heater opposite to the air inlet of the fan is symmetrically arranged along the center of the mounting opening; the cover plate and the wind collecting plate are spaced apart and connected to the opening of the box body; the panel is provided with an air outlet of the heater which cooperates with the outer peripheral edge of the air outlet of the air deflector; the panel and the cover plate are spaced apart, and together with the cover plate, the air deflector and the box body form an air inlet channel for air to enter the fan; the outer peripheral edge of the air deflector is matched with the mounting opening on the cover plate, and the cover plate is connected to the opening of the box body to form a certain accommodation space.

[0049] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] like Figure 3 A specific embodiment of the flow guide device shown includes a flow guide housing 1 having an installation space, a swing angle drive mechanism 2 arranged in the installation space, and a rotation angle drive mechanism 3 arranged outside the flow guide housing 1.

[0051] A groove is opened on the guide shell 1, and the guide shell 1 includes an arc-shaped windward guide part 11 and an arc-shaped leeward guide part 12; the two are connected to form an integrated structure with an accommodating space through a smooth curved surface that converges toward the center of the guide shell 1, and the curvature of the windward guide part 11 is greater than the curvature of the leeward guide part 12; specifically, the windward guide part 11 and the leeward guide part 12 are two semicircular arc surfaces, which together form a guide shell 1 with a circular cross-section and an olive-shaped longitudinal section, and the windward guide part 11 is arranged close to the corner drive mechanism 3, and the leeward guide part 12 is arranged away from the corner drive mechanism 3.

[0052] The swing angle drive mechanism 2 includes a bracket 21 and a swing angle drive structure 22 disposed at one end of the bracket 21. Specifically, the swing angle drive structure 22 is a motor with a horizontally arranged output shaft, which is fixedly connected to the diversion housing 1 and is suitable for driving the diversion housing 1 to swing vertically at a certain angle. The other end of the bracket 21 extends out of the diversion housing 1 through a slot, and a space is reserved in the slot. When the diversion housing 1 swings, it does not interfere with the bracket 21. A pair of brackets 21 are symmetrically provided to ensure balance.

[0053] The driving end of the rotation angle driving mechanism 3 is connected to the other end of the bracket 21, and is suitable for driving the bracket 21 and driving the guide housing 1 to rotate in the horizontal direction. Specifically, the rotation angle driving mechanism 3 is a motor with a vertically arranged output shaft.

[0054] Furthermore, a deflector cover 4 is provided outside the deflector shell 1. The shape of the deflector cover 4 is basically the same as that of the deflector shell 1. It has a first accommodating space, an air inlet and an air outlet. The air inlet is arranged close to the corner drive mechanism 3, and the air outlet is arranged away from the corner drive mechanism 3. The air inlet and the air outlet are connected by a deflector plate to form a first accommodating space; the deflector shell 1 is arranged in the first accommodating space, and a deflector flow channel is formed between the deflector plate. The flow channel is a structure that gradually expands outward from the air inlet to the air outlet and then converges to the center.

[0055] like Figure 1-5 As shown, a specific embodiment of the heater with the above-mentioned guide device provided by the present invention includes a main body with a pair of symmetrically arranged air supply mechanisms 5, and the air supply mechanism 5 includes a fan 51, a guide plate 52 and a guide plate 53; specifically, the rotating shaft of the fan 51 is arranged in the vertical direction, and after the blades accelerate the air, the air flow is blown out along the tangential direction of the rotation of the blades.

[0056] The guide plate 52 is arranged in a spiral shape along the tangential direction of the outer edge of the fan 51 and extends to transitionally connect with the air inlet of the air deflector 4. Specifically, the guide plate 52 is arranged along the generatrix direction of the outer edge of the fan 51, extending from the tangential direction of the side of the fan 51 away from the air deflector 4, and extending in a spiral shape to the side of the air inlet of the air deflector 4.

[0057] The guide plate 53 is smoothly connected to the guide plate 52 in the direction of the air guide cover 4 , forming a smooth air guide duct toward the air guide cover 4 .

[0058] As an alternative embodiment, there may be only one air supply mechanism 5 .

[0059] Furthermore, the main body also includes a box body 6, an air collecting plate 7, a PTC heater, a cover plate 8, and a panel 9;

[0060] Specifically, a rectangular box body 6 is provided at the center with a motor having an output shaft arranged in a vertical direction. Two sets of air supply mechanisms 5 are symmetrically distributed along the output shaft of the motor. The guide plates 53 of the two sets of air supply mechanisms 5 and the box body 6 enclose a third accommodation space. The corner drive mechanism 3 is disposed in the third accommodation space. Its driving end extends through the guide plate 53 and is connected to the bracket 21 of the swing angle drive mechanism 2.

[0061] The air collecting plate 7 is arranged at the mouth of the box body 6, and an air supply port is opened in the middle thereof, which is opposite to the air outlet of the drainage air duct. The air supply port is matched with the outer periphery of the air inlet of the deflector 4; the fan air inlets are symmetrically arranged along the center of the air supply port, which are opposite to the fans 51 of the two sets of air supply mechanisms 5 respectively.

[0062] The PTC heater is arranged in the air duct between the air outlet of the guide air duct and the guide housing 1;

[0063] The cover plate 8 is arranged on the side of the air collecting plate 7 away from the fan 51, and has a mounting opening on it that matches the outer peripheral edge of the air deflector 4; the heater air inlet is symmetrically arranged along the center of the mounting opening, opposite to the air inlet of the fan 51; the cover plate 8 is spaced apart from the air collecting plate 7 and connected to the opening of the box body 6;

[0064] The panel 9 is provided with a heater outlet that matches the outer periphery of the air outlet of the air deflector 4; the panel 9 is spaced apart from the cover 8, and together with the cover 8, the air deflector 4 and the box body 6 form an air inlet channel suitable for air to enter the fan 51.

[0065] Furthermore, it also includes a human body sensor and a control module; the human body sensor is arranged on a side of the panel 9 in the extension direction toward the air outlet of the heater, and is electrically or wirelessly connected to the control module;

[0066] The control module is also electrically or wirelessly connected to the swing angle drive structure 22 and the rotation angle drive mechanism 3 .

[0067] When the heater provided by the present invention is working, the fan 51 rotates, and the blades accelerate the air around the rotation direction of the fan 51. Negative pressure is formed at the rotation center of the fan 51 and in the space between the wind collecting plate 7, the cover plate 8, and the box body 6. The air outside the box body 6 enters the center of the fan 51 through the air duct between the panel 9, the air guide cover 4, and the cover plate 8. The fan 51 blows the accelerated airflow along the guide plate 52 and the guide plate 53 into the air inlet of the air guide cover 4. The PTC heater arranged in the flow channel can heat the airflow. After the airflow enters from the air inlet of the air deflector 4, it is evenly distributed to the surroundings along the windward guide part 11, and flows along the flow channel between the air deflector shell 1 and the air deflector 4 along the surface of the windward guide part 11. The flow channel first expands outwards and then converges toward the center, which can accelerate the airflow twice. The air outlet of the air deflector 4 converges toward the leeward guide part 12, so that the accelerated airflow converges toward the center. Under the action of acceleration and convergence, the airflow can be blown to a farther distance.

[0068] In the initial state, the guide device remains in a vertical state, with the angle α between its center line and the vertical direction equal to 0, and the airflow blows warm air along the center line of the guide device. When the human body sensor is turned on, the human body sensor detects the human body position in real time. With the center of the guide device as the center of the circle, the horizontal distance from the human body position to the center of the guide device is R. If 0<R<R1, the control module controls the swing angle drive mechanism 2 to drive the guide housing 1 to swing at an angle α1, as shown in FIG. Figure 5As shown; if R1≤R≤R2, the control module controls the swing angle drive mechanism 2 to drive the diversion housing 1 to swing by an angle α2; if R>R2, the control module controls the swing angle drive mechanism 2 to drive the diversion housing 1 to swing by an angle α3 (where R1, R2, h1, h2, and h3 are all constants, and α1<α2<α3). In addition, when the diversion housing 1 deviates from the center position (i.e., α>0), the rotation angle drive mechanism 3 will drive the bracket 21 and the diversion housing 1 to rotate at a low speed, achieving 360° omnidirectional air supply, effectively expanding the air supply range.

[0069] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
