Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and more specifically, to a heating device. Background Technology

[0002] Heating equipment, which outputs warm air, is widely used in daily life. For example, bathroom heaters are installed in bathrooms. Currently, in the operation of bathroom heaters, when the high-speed airflow from the main unit's outlet flows towards the outlet of the faceplate, the airflow first hits the side wall of the faceplate outlet, which is far from the main unit's outlet and perpendicular to the airflow direction, before leaving the outlet and entering the room to achieve the heating function. This airflow method is not smooth, greatly increasing airflow loss, reducing the product's airflow speed, and generating noise. Furthermore, when the airflow leaves the product's outlet and enters the bathroom, its direction is to diffuse horizontally along the air duct. Due to the characteristics of hot airflow, its diffusion speed in the room is slow, making it difficult to diffuse to the ground, affecting the overall temperature rise of the bathroom and significantly impacting the heating effect.

[0003] As can be seen from the above, current heating equipment suffers from problems such as poor airflow and a poor user experience during use. Summary of the Invention

[0004] The main objective of this invention is to provide a heating device to solve the problems of poor airflow and poor user experience in existing heating devices.

[0005] To achieve the above objectives, according to one aspect of the present invention, a heating device is provided. The heating device includes a main unit having a accommodating cavity and an air inlet communicating with the accommodating cavity; a face mask vertically mounted on the main unit; a fan installed inside the accommodating cavity; the fan having a fan outlet structure; and an air guide plate movably disposed between the fan outlet structure and the face mask. The air guide plate has a closed position that blocks the fan outlet structure and an open position that avoids the fan outlet structure. The lifting movement of the face mask provides a driving force for switching the air guide plate between the open and closed positions.

[0006] Furthermore, the fan outlet structure is a fan outlet duct, with the first end of the guide plate rotatably connected to the fan outlet duct and the second end of the guide plate slidably connected to the mask. The lifting and lowering movement of the mask causes the second end of the guide plate to slide, thereby opening or closing the fan outlet duct; or the first end of the guide plate is rotatably connected to the mask and the second end of the guide plate is slidably connected to the fan outlet duct. The lifting and lowering movement of the mask causes the second end of the guide plate to slide, thereby opening or closing the fan outlet duct.

[0007] Furthermore, the mask has a mask air outlet structure, and the fan air outlet structure is connected to the mask air outlet structure to form an air outlet duct. The air guide plate is adjustablely positioned inside the air outlet duct.

[0008] Furthermore, the mask includes a mask body with a mask air outlet; and an air guide structure, which is a hollow structure. The first end of the air guide structure is connected to the mask air outlet, and the second end of the air guide structure is connected to the fan air outlet structure. The mask air outlet and the air guide structure together form the mask air outlet structure.

[0009] Furthermore, the first end of the air guide plate is rotatably connected to the air outlet duct of the fan, the second end of the air guide plate is slidably connected to the face mask, the first end of the air guide plate has first rotating parts on both sides, and a first rotating structure is provided on a set of inner wall surfaces of the air outlet duct of the fan, with the first rotating parts and the first rotating structure rotating in cooperation.

[0010] Furthermore, the first rotating component is a first rotating shaft, the first rotating structure is a through hole, and at least a portion of the first rotating shaft extends into the through hole and is rotatably connected to the through hole.

[0011] Furthermore, a second rotating shaft is provided on both sides of the second end of the air guide plate, and a set of sliding grooves is provided on the air guide structure of the mask opposite to the second rotating shaft. At least a part of the second rotating shaft extends into the interior of the sliding groove, and the second rotating shaft is rotatably disposed in the sliding groove and can slide along the length direction of the sliding groove.

[0012] Furthermore, the second end of the air guide structure of the mask is fitted outside the air outlet duct of the fan. When the air guide plate is in the open position, the second end of the air guide plate abuts against the first side wall of the air guide structure in the radial direction to form an air outlet duct.

[0013] Furthermore, when the air guide plate is in the open position, the inner walls of the fan outlet air duct, the air guide plate, and the air guide structure in the air outlet duct are collinear.

[0014] Furthermore, the air guide structure is provided with a support section. When the air guide plate is in the open position, the second end of the air guide plate abuts against the support section to form an air outlet duct. The support section is located on the first side wall of the air guide structure along the radial direction.

[0015] Furthermore, when the air guide plate is in the closed position, the second end of the air guide plate abuts against the second side wall of the fan outlet duct to close the fan outlet duct, and the second side wall is opposite to the first side wall.

[0016] Furthermore, when the air guide plate is in the closed position, the second end of the air guide plate abuts against the second side wall of the fan outlet duct and the first side wall of the air guide structure to close the fan outlet duct.

[0017] Furthermore, the first sidewall of the air guide structure is provided with an opening section, a clearance section and a support section in sequence. The opening section is connected to the fan outlet structure. A clearance groove is formed at the clearance section. The clearance groove is used to provide space for placing the air guide plate and / or the fan outlet duct when the air guide plate is in the closed position.

[0018] Furthermore, the support section is a protruding structure set on the inner wall surface of the air guide structure; and / or the support section is a concave bending section on the air guide structure.

[0019] Furthermore, the extension direction of the opening section is the same as the extension direction of the fan outlet structure; the support section is parallel to the opening section and not collinear, and the distance between the support section and the axis of the fan is greater than the distance between the opening section and the axis.

[0020] Furthermore, during the lifting and lowering process of the mask, the support section of the air guide structure abuts against the air guide plate and can slide relative to it.

[0021] Furthermore, the mask body has a base plate and a surrounding plate arranged circumferentially along the base plate, and the mask air outlet is arranged on the base plate and / or the surrounding plate.

[0022] Furthermore, the fan outlet structure is a fan outlet duct, the extension direction of the fan outlet duct is set at an angle to the axis of the fan, and the outlet area of ​​the fan outlet duct is located inside the opening area at the second end of the air guide structure.

[0023] Furthermore, along the length of the main unit, the distance between the first end of the air guide plate and the fan axis is less than the distance between the second end of the air guide plate and the fan axis. When the air guide plate is in the open position, an air outlet duct for gas flow is formed between the inner wall of the fan outlet duct, the air guide plate, and the inner wall of the air guide structure.

[0024] According to the technical solution of the present invention, the heating equipment includes a main unit, a face shield, a fan, and an air guide plate. The main unit has a receiving cavity and an air inlet connected to the receiving cavity. The face shield is movably mounted on the main unit and has a face shield air outlet structure. The fan is installed inside the receiving cavity and has a fan air outlet structure. The fan air outlet structure is connected to the face shield air outlet structure to form an air outlet duct. The air guide plate is adjustablely positioned inside the air outlet duct. The air guide plate has a closed position that blocks the fan air outlet structure and an open position that avoids the fan air outlet structure. The lifting and lowering movement of the face shield provides driving force for the air guide plate to switch between the open and closed positions.

[0025] As can be seen from the above, the heating equipment of this application adopts a lifting and lowering ground cover, so that the position of the air guide plate is moved by the lifting and lowering of the cover, without the need to set up a separate drive structure to drive the air guide plate to move. This application controls the opening and closing of the fan outlet structure by adjusting the position of the air guide plate, thereby controlling whether to supply air to the outside, improving the controllability of the air direction, so that the air guide plate has the effect of guiding air when it is in the open position, avoiding the problem of airflow collision causing poor circulation and noise, and improving the user experience.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0041] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0042] In order to solve the problems of poor airflow and poor user experience in existing heating equipment, the present invention provides a heating device.

[0043] In this embodiment, the heating device is a bathroom heater.

[0044] like Figures 1 to 10 As shown, the heating equipment includes a main unit 10, a face shield 20, a fan 30, and an air guide plate 60. The main unit 10 has a receiving cavity 120 and an air inlet 110 communicating with the receiving cavity 120. The face shield 20 is movably mounted on the main unit 10. The fan 30 is installed inside the receiving cavity 120 and has a fan outlet structure. The air guide plate 60 is movably mounted between the face shield 20 and the fan outlet structure. The air guide plate 60 has a closed position that blocks the fan outlet structure and an open position that avoids the fan outlet structure. The lifting and lowering movement of the face shield 20 provides driving force for the air guide plate 60 to switch between the open and closed positions.

[0045] In one embodiment, the first end of the air guide plate 60 can be rotatably connected to the fan outlet structure, and the second end of the air guide plate 60 can be slidably connected to the mask outlet structure. The lifting and lowering movement of the mask 20 causes the second end of the air guide plate 60 to slide, thereby opening or closing the fan outlet duct 320. Alternatively, the first end of the air guide plate 60 can be rotatably connected to the mask 20, and the second end of the air guide plate 60 can be slidably connected to the fan outlet duct 320. The lifting and lowering movement of the mask 20 causes the second end of the air guide plate 60 to slide, thereby opening or closing the fan outlet duct 320. Both embodiments are feasible. The specific structure of the air guide plate 60 allows one end to slide within the slide groove 510 during the lifting and lowering of the mask 20, while the other end of the air guide plate 60 rotates, achieving simultaneous sliding and rotation of the air guide plate 60 for position adjustment.

[0046] Furthermore, the fan outlet structure is a fan outlet duct 320, and the air guide plate 60 blocks or avoids the outlet end of the fan outlet duct 320.

[0047] As can be seen from the above, the heating equipment of this application adopts a lifting and lowering ground cover 20, so that the air guide plate 60 can be moved by lifting and lowering the cover 20, without the need to set up a separate drive structure to drive the air guide plate 60 to move. This application controls the opening and closing of the fan outlet air duct 320 by adjusting the position of the air guide plate 60, thereby controlling whether to supply air to the outside, which improves the controllability of the air direction. At the same time, one end of the air guide plate 60 is rotatably connected and the other end is slidably connected, so that the air guide plate 60 has the effect of guiding air when it is in the open position, avoiding the problem of airflow collision causing poor circulation and noise, thus improving the user experience.

[0048] Furthermore, the main unit 10 is installed on the ceiling of the bathroom to enable positioning of the main unit 10.

[0049] It should be noted that the outlet end of the fan outlet duct 320 is a rectangular pipe with a rectangular opening, and the air guide plate 60 is a rectangular plate. The position of the air guide plate 60 can be adjusted to block or avoid the fan outlet duct 320.

[0050] In this embodiment, the fan 30 also has a fan inlet 310, which is connected to the accommodating cavity 120.

[0051] The heating equipment has a standby state and an operating state. When the heating equipment is in the standby state, the cover 20 is hidden inside the main unit 10, and the air guide plate 60 blocks the fan outlet air duct 320. When the heating equipment is in the operating state, the cover 20 is raised, the air guide plate 60 is in the open position, and the gas flowing out of the fan outlet air duct 320 flows out of the main unit 10 under the guidance of the air guide plate 60.

[0052] like Figures 1 to 10 As shown, the mask 20 has a mask air outlet structure, and the fan air outlet duct 320 is connected to the mask air outlet structure to form an air outlet duct. The air guide plate 60 is adjustablely disposed inside the air outlet duct, and one end of the air guide plate 60 is movably connected to the mask air outlet structure.

[0053] During the lifting and lowering of the mask 20, the air outlet duct 320 of the fan and the air outlet structure of the mask remain in constant communication.

[0054] Specifically, during the lifting and lowering of the mask 20, the mask air outlet structure drives the air guide plate 60 to switch positions inside the air outlet duct. When the mask 20 is lowered and hidden in the main unit 10, the air guide plate 60 is in a closed position to block the fan air outlet duct 320. When the mask 20 is raised to expose at least part of it, the air guide plate 60 switches to an open position under the drive of the mask air outlet structure. The air guide plate 60 avoids the fan air outlet duct 320, at which time the fan air outlet duct 320 can supply air to the outside.

[0055] In this embodiment, the fan 30 is a hot air fan 30, that is, a heating element 40 is provided inside the fan outlet duct 320, so that the airflow flowing out of the fan outlet duct 320 is heated into hot airflow when it passes through the heating element 40 to achieve the technical effect of heating.

[0056] Furthermore, the fan 30 has a fan inlet 310, and the fan inlet 110, the fan inlet 310, the fan outlet duct 320, and the mask outlet 210 of the mask 20 form an air duct.

[0057] like Figures 1 to 10 As shown, the mask 20 includes a mask body and an air guide structure 50. The mask body is provided with a mask air outlet 210. The air guide structure 50 is a hollow structure. The first end of the air guide structure 50 is connected to the mask air outlet 210, and the second end of the air guide structure 50 is connected to the fan air outlet duct 320. The mask air outlet 210 and the air guide structure 50 form the mask air outlet structure.

[0058] Specifically, the air guide structure 50 is an air guide channel. The gas flowing out of the fan outlet duct 320 enters the interior of the air guide structure 50 and flows out through the mask outlet 210 to the external space of the heating equipment.

[0059] Furthermore, the mask body has a base plate and a surrounding plate arranged circumferentially along the base plate, and the mask air outlet 210 is arranged on the base plate and / or the surrounding plate.

[0060] It should be noted that the first end of the air guide structure 50 is sealed to the air outlet 210 of the mask; the second end of the air guide structure 50 is also sealed to the air outlet duct 320 of the fan. Specifically, the sealing connection can be achieved by installing sealing gaskets or sealing sleeves at the connection points to prevent gas backflow or dust accumulation due to gaps.

[0061] In this embodiment, the opening direction of the fan outlet duct 320 is set at an angle to the axis of the fan 30, and the opening area of ​​the fan outlet duct 320 is located inside the opening area of ​​the second end of the air guide structure 50, so that the fan outlet duct 320 remains connected to the air guide structure 50 during the lifting and lowering of the mask 20.

[0062] During the lifting and lowering movement of the mask 20, the air guiding structure 50 of the mask 20 also lifts and lowers accordingly. When the air guiding structure 50 moves toward the fan outlet duct 320, in order to avoid the collision between the air guiding structure 50 and the fan outlet duct 320, the opening area of ​​the air guiding structure 50 is larger than the opening area of ​​the fan outlet duct 320.

[0063] like Figures 1 to 10 As shown, the wall surface of the air guide structure 50 near the axis of the fan 30 has an opening section 521, a clearance section 522 and a support section 523 connected in sequence. The opening section 521 is connected to the fan outlet structure. A clearance groove is formed at the clearance section 522. The clearance groove is used to provide space for placing the air guide plate 60 and / or the fan outlet air duct 320 when the air guide plate 60 is in the closed position.

[0064] Furthermore, the extension direction of the opening section 521 is the same as the extension direction of the fan outlet structure, the support section 523 is parallel to the opening section 521 and not collinear, and the distance between the support section 523 and the axis of the fan 30 is greater than the distance between the opening section 521 and the axis.

[0065] Among them, such as Figure 3 and Figure 4 As shown, the shape of the avoidance section 522 can be formed by a single bending, such as an L-shape; as Figure 5 As shown, the shape of the clearance section 522 can also be formed by multiple bends. When the air guide plate 60 is in the closed position, at least a portion of the air guide plate 60 is inside the clearance groove to accommodate the air guide plate 60.

[0066] Furthermore, along the length of the main unit 10, the distance between the first end of the air guide plate 60 and the axis of the fan 30 is less than the distance between the second end of the air guide plate 60 and the axis of the fan 30. When the air guide plate 60 is in the open position, an air outlet duct for gas flow is formed between the air guide plate 60 and the inner wall surface of the air guide structure 50.

[0067] Specifically, when the air guide plate 60 is in the open position, the air guide plate 60 is set at an angle to the axis of the fan 30, so as to be inclinedly set inside the air outlet duct. The guide slope of the air guide plate 60 and the inner wall of the air guide structure 50 form an air outlet duct for gas flow, so as to achieve the function of air guidance, avoid the phenomenon of gas collision caused by vertical flow between the gas and the air guide structure 50, improve the smoothness of gas flow, and reduce noise.

[0068] In this embodiment, when the air guide plate 60 is in the open position, the extension direction of the guide slope is the same as the orientation of the fan outlet air duct 320, so that the air guide plate 60 has a good air guiding effect.

[0069] like Figures 1 to 10 As shown, the air guide plate 60 is a rectangular plate, and the first end of the air guide plate 60 has first rotating parts on both sides. A first rotating structure is provided on a set of inner wall surfaces of the fan outlet air duct 320, and the first rotating parts are rotatably engaged with the first rotating structure.

[0070] Furthermore, the first rotating component is a first rotating shaft 610, and the first rotating structure is a through hole, with at least a portion of the first rotating shaft 610 extending into the through hole and rotatably connected to it.

[0071] Of course, the first rotating component and the first rotating structure are not limited to the above-mentioned rotating shaft and rotating hole cooperation rotation form, but can also be a rotating shaft and rotating groove cooperation structure form.

[0072] In this embodiment, the first end of the air guide plate 60 is rotatably engaged with the air outlet duct 320 of the fan so that the first end of the air guide plate 60 can rotate during the lifting and lowering of the mask 20, thereby enabling the air guide plate 60 to switch between the open and closed positions.

[0073] like Figures 1 to 10 As shown, the second end of the air guide structure 50 is sleeved outside the fan outlet duct 320. When the air guide plate 60 is in the open position, the second end of the air guide plate 60 abuts against the first side wall of the air guide structure 50 in the radial direction to form an outlet duct. One of the outer wall surfaces of the fan outlet duct 320 is collinear with the air guide plate 60, and the other outer wall surfaces of the fan outlet duct 320 abut against the inner wall surface of the air guide structure 50 to form a sealed outlet duct.

[0074] Specifically, to achieve a sealing effect, a sealing gasket is provided on the outer wall of the fan outlet duct 320, forming a seal between the outer wall of the fan outlet duct 320 and the inner wall of the air guide structure 50. Of course, the sealing gasket can also be provided on the inner wall of the air guide structure 50.

[0075] like Figures 1 to 10As shown, the air guide plate 60 is a rectangular plate, and the second ends of the air guide plate 60 are provided with second rotating shafts 620 on both sides. The air guide structure 50 of the mask 20 is provided with a set of sliding grooves 510 opposite to the second rotating shafts 620. At least a part of the second rotating shaft 620 extends into the interior of the sliding groove 510. The second rotating shaft 620 is rotatably disposed in the sliding groove 510 and can slide along the length direction of the second sliding groove 510.

[0076] Specifically, the second end of the air guide plate 60 is slidably engaged with the air guide structure 50 so that during the lifting and lowering of the mask 20, the slide groove 510 lifts and lowers to drive the second end of the air guide plate 60 to achieve a flipping motion, thereby enabling the air guide plate 60 to switch between the open position and the closed position.

[0077] Furthermore, the rotation angle of the air guide plate 60 is achieved by adjusting the extension direction of the slide groove 510.

[0078] Furthermore, the extension direction of the chute 510 is angled to the horizontal direction. Depending on the position of the guide plate 60 inside the chute 510, the guide plate 60 is in different positions. When the guide plate 60 is in the open position, the inner wall of the fan outlet duct 320, the guide plate 60, and the support section 523 of the guide structure 50 are collinear. When the guide plate 60 is in the closed position, the guide plate 60 is housed inside the guide structure 50, and the guide plate 60 abuts against the open end of the fan outlet duct 320 to block the fan outlet duct 320.

[0079] It should be noted that the support section 523 is located on the first side wall of the air guide structure 50 along the radial direction.

[0080] When the air guide plate 60 is in the closed position, the second end of the air guide plate 60 abuts against the second side wall of the fan outlet air duct 320 to close the fan outlet air duct 320, and the second side wall is opposite to the first side wall.

[0081] When the air guide plate 60 is in the closed position, the second end of the air guide plate 60 abuts against the second side wall of the fan outlet air duct 320 and the first side wall of the air guide structure 50 respectively, so as to close the fan outlet air duct 320.

[0082] In this embodiment, the air guide structure 50 has a support section 523. During the lifting and lowering process of the mask 20, the support section 523 abuts against the air guide plate 60 and can slide relative to it. The first end of the support section 523 abuts against the air guide plate 60, and the second end of the support section 523 is connected to the mask body. When the air guide plate 60 is in the closed position, the gas flowing out of the fan outlet 320 flows towards the mask outlet 210 along the inner wall of the support section 523 under the guidance of the air guide plate 60.

[0083] The support section 523 can be a protruding structure set on the inner wall surface of the air guide structure 50. The support section 523 can also be a concave bending section on the air guide structure 50, that is, a bending section set towards the inside of the air guide structure 50. Of course, the support section 523 can also be a combination of a bending section and a protruding structure, specifically to achieve the abutment and sliding fit between the support section 523 and the air guide plate 60.

[0084] Furthermore, when the air guide plate 60 is in the open position, the support section 523 is collinear with the inner wall surface of the fan outlet duct 320 and the air guide plate 60; when the air guide plate 60 switches from the open position to the closed position, the support section 523 provides driving force for the air guide plate 60 to block the movement of the fan outlet duct 320.

[0085] like Figures 1 to 10 As shown, the heating equipment also includes a drive component 80 and a transmission component 70. The drive component 80 is installed inside the accommodating cavity 120, and the transmission component 70 is disposed on the mask 20. The drive component 80 is connected to the mask 20 through the transmission component 70, and the drive component 80 provides driving force for the mask 20 to rise and fall.

[0086] Specifically, the driving component 80 is a motor, and a gear is provided on the output shaft of the motor. The transmission component 70 is a rack mounted on the mask 20. The rack meshes with the gear. Under the driving action of the driving component 80, the gear drives the rack to move along the depth direction of the receiving groove to realize the lifting and lowering movement of the mask 20.

[0087] In this embodiment, the axis of the fan 30 is collinear with the center line of the accommodating cavity 120, so that the gas enters the accommodating cavity 120 and then enters the fan 30 evenly.

[0088] Furthermore, the fan 30 has one or more fan outlet ducts 320, and each fan outlet duct 320 is equipped with a guide vane 60.

[0089] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0090] The heating equipment of this application adopts a lifting and lowering ground cover 20, so that the position of the air guide plate 60 is moved by the lifting and lowering of the cover 20, without the need for a separate drive structure to drive the movement of the air guide plate 60. This application controls the opening and closing of the fan outlet duct 320 by adjusting the position of the air guide plate 60, thereby controlling whether air is supplied to the outside, improving the controllability of the air direction. At the same time, one end of the air guide plate 60 is rotatably connected and the other end is slidably connected, so that the air guide plate 60 has the effect of guiding air when it is in the open position, avoiding the problem of airflow collision causing poor circulation and noise, thus improving the user experience.

[0091] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention.
