Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a swing structure and a bathroom heater. Background Technology

[0002] A fan-type bathroom heater is commonly used for heating bathrooms. The heater is installed in the ceiling space of the bathroom, and the warm air heated by the heater enters the bathroom through the air outlet to raise the temperature of the bathroom.

[0003] In existing technology, bathroom heaters typically have swivel blades installed at the air outlet to achieve the swing effect. The swivel blades guide the warm air, and the rotation of the swivel blades is driven by a stepper drive device to change the air outlet angle, thereby achieving the swing effect.

[0004] However, when the blades are applied to extremely narrow air outlets, the width of the blades is limited, which affects their air guiding effect. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the oscillating blade air outlet structure has poor guiding effect when applied to extremely narrow air outlets in the prior art, thereby providing an oscillating structure and a bathroom heater.

[0006] To solve the above-mentioned technical problems, this utility model provides a swing structure, including: a housing and a guide member; the housing is provided with an air outlet, and the housing has an air supply channel communicating with the air outlet; the guide member is vertically and elliptically disposed at the air outlet of the housing, the guide member is provided with a guide surface on at least one side, the guide surface has at least two bent parts, and the guide surface is spaced apart from the inner sidewall of the air supply channel.

[0007] In use, the guide component moves up and down reciprocally along the air supply channel at the air outlet of the housing. Different parts of the guide surface are bent at different angles to the inner wall of the air supply channel. As the guide component moves up and down, different parts of the guide surface reach the air outlet, allowing air in the air supply channel to be blown out from the air outlet at different angles, thus achieving a swing effect. The length of the guide surface on the guide component can be greater than the width of the air outlet, thus meeting the air guiding effect requirements of extremely narrow air outlets. The swing structure provided by this invention solves the problem of poor guiding effect of existing louvered air outlet structures applied to extremely narrow air outlets.

[0008] Optionally, the guide member has guide surfaces on both sides, and both guide surfaces are spaced apart from the inner wall of the air supply channel. Through this arrangement, the guide member divides the air supply channel into dual air ducts, achieving a dual-air duct swing effect and increasing the blowing angle at the air outlet.

[0009] Optionally, the guide surface includes a first guide surface and a second guide surface. Along the direction from the inside to the outside of the housing, the angle between the first guide surface and the second guide surface relative to the inner wall of the air supply channel gradually decreases. With this configuration, when the air supply channel delivers air vertically downwards, when the guide member is in the first position, the air delivered to the air outlet by the air supply channel has a larger angle between its outlet direction and the vertical direction under the guidance of the first guide surface. When the guide member is in the second position, the air delivered to the air outlet by the air supply channel has a smaller angle between its outlet direction and the vertical direction under the guidance of the second guide surface. As the guide member moves up and down reciprocally, the outlet direction changes, achieving a swing effect.

[0010] Optionally, the first guide surface is inclined relative to the air supply direction of the air supply channel, and the second guide surface is parallel to the air supply direction of the air supply channel. With this configuration, when the air supply channel delivers air vertically downwards, when the guide member is in the first position, the air delivered to the outlet by the air supply channel changes from vertically downwards to being blown obliquely outwards along the first guide surface under the guidance of the first guide surface; when the guide member is in the second position, the air delivered to the outlet by the air supply channel remains vertically downwards under the guidance of the second guide surface; as the guide member moves up and down repeatedly, the air outlet direction changes, achieving a swing effect.

[0011] Optionally, the housing has an internal mounting groove with the same width as the air outlet. The mounting groove forms an air supply channel extending into the housing. The guide member is vertically and flexibly positioned within the mounting groove. This configuration creates an air supply channel on the housing with the same width as the air outlet, guiding the airflow. The guide member moves up and down along the air supply channel within the mounting groove, changing the airflow direction and achieving a swing effect.

[0012] Optionally, an installation space is formed between the mounting groove and the housing. A lifting mechanism is provided on the outer wall of the mounting groove, and the lifting mechanism is located within the installation space. The drive end of the lifting mechanism is connected to the guide member. With the above arrangement, the lifting mechanism is located in the installation space between the mounting groove and the housing, which does not occupy the space of the air supply channel, reducing the space occupied by the lifting mechanism at the air outlet, and enabling the swing structure to be applied to extremely narrow air outlets.

[0013] Optionally, the lifting mechanism includes a drive device and a transmission assembly. The drive device is fixedly mounted on the outer wall of the mounting groove. The transmission assembly is disposed at the drive end of the drive device and is connected to the guide member. With this configuration, the drive device drives the guide member to move up and down along the mounting groove via the transmission assembly, allowing the drive device to be moved away from the air outlet, reducing the space occupied at the air outlet, thus making it suitable for extremely narrow air outlets.

[0014] Optionally, the transmission assembly includes a turntable and a rope; the turntable is disposed at the drive end of the drive device, and the drive device drives the turntable to rotate; the rope is wound around the turntable, and the end of the rope is connected to the guide member. With the above arrangement, the drive device drives the turntable to rotate, and the turntable winds and unwinds the rope, thereby realizing the lifting and lowering movement of the guide member.

[0015] Optionally, at least two fixing posts are provided on the outer wall of the mounting groove, and at least two fixing plates are provided on the driving device, with the fixing plates fixedly connected to the fixing posts. Through this arrangement, the fixing posts provide mounting space for the turntable between the driving device and the outer wall of the mounting groove, and the side wall of the mounting groove blocks the driving end of the driving device, preventing the turntable from detaching from the driving end of the driving device.

[0016] Optionally, one lifting mechanism is provided at each end of the mounting groove. With this arrangement, the two lifting mechanisms drive the guide member to move up and down from both ends, making the lifting and moving of the guide member more stable.

[0017] Optionally, a guide groove is provided on the side wall of the mounting groove, and a guide post is provided on the guide member, with the guide post slidably disposed within the guide groove. Through this arrangement, the guide groove guides and limits the guide post, thus guiding and limiting the lifting and lowering movement of the guide member, preventing swaying during the lifting and lowering process.

[0018] This utility model provides a bathroom heater, including a main body and a swing structure as described in any of the above-mentioned solutions. The swing structure is disposed at the air outlet end of the main body. It can achieve a swing effect at the air outlet end of the bathroom heater, and due to the use of the above-mentioned swing structure, it has any of the aforementioned advantages.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] This embodiment provides a swing structure that can be applied to extremely narrow air outlets to achieve a swing effect at the air outlet.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 5 The diagram shows a specific implementation of a swing structure provided in this embodiment, comprising: a housing 1 and a guide member 3; the housing 1 is provided with an air outlet, and the housing 1 has an air supply channel communicating with the air outlet; the guide member 3 is vertically and flexibly disposed at the air outlet of the housing 1, and the guide member 3 is provided with a guide surface 4 on at least one side, the guide surface 4 having at least two bent parts, and the guide surface 4 being spaced apart from the inner sidewall of the air supply channel.

[0034] In use, the guide member 3 moves up and down reciprocally along the air supply channel at the air outlet of the housing 1. Different parts of the guide surface 4 are bent at different angles to the inner wall of the air supply channel. As the guide member 3 moves up and down reciprocally, different parts of the guide surface 4 move to the air outlet, allowing the air in the air supply channel to be blown out of the air outlet at different angles, thereby achieving a swing effect. The length of the guide surface 4 on the guide member 3 can be greater than the width of the air outlet, thus satisfying the air guiding effect of an extremely narrow air outlet. The swing structure provided in this embodiment solves the problem of poor guiding effect of the existing sway blade air outlet structure when applied to extremely narrow air outlets.

[0035] like Figure 1 , Figure 2 As shown, in the swing structure provided in this embodiment, guide surfaces 4 are provided on both sides of the guide member 3, and both guide surfaces 4 are spaced apart from the inner sidewall of the air supply channel. The guide member 3 divides the air supply channel into a dual air duct, which can achieve a dual air duct swing effect and make the blowing range angle at the air outlet larger. In addition, as an alternative implementation, the guide member 3 may also have a guide surface 4 on only one side.

[0036] like Figure 1 , Figure 2 As shown, in the swing structure provided in this embodiment, the guide surface 4 includes a first guide surface 6 and a second guide surface 7, which are bent. When the air supply channel delivers air vertically downwards, when the guide member 3 is in the first position, the air delivered to the air outlet by the air supply channel has a larger angle between its outlet direction and the vertical direction under the guidance of the first guide surface 6. When the guide member 3 is in the second position, the air delivered to the air outlet by the air supply channel has a smaller angle between its outlet direction and the vertical direction under the guidance of the second guide surface 7. As the guide member 3 moves up and down reciprocally, the outlet direction changes, achieving a swing effect. Alternatively, as an alternative implementation, the guide surface 4 can be configured as three or more parts with different inclination angles, depending on the requirements.

[0037] like Figure 1 , Figure 2 As shown, in the swing structure provided in this embodiment, the first guide surface 6 is inclined relative to the air delivery direction of the air delivery channel, and the second guide surface 7 is parallel to the air delivery direction of the air delivery channel. When the air delivery channel delivers air vertically downwards, when the guide member 3 is in the first position, the air delivered to the air outlet by the air delivery channel changes from vertically downwards to obliquely outwards along the first guide surface 6 under the guidance of the first guide surface 6; when the guide member 3 is in the second position, the air delivered to the air outlet by the air delivery channel is vertically downwards under the guidance of the second guide surface 7; as the guide member 3 moves up and down repeatedly, the air outlet direction changes, achieving a swing effect. Alternatively, as an alternative embodiment, the second guide surface 7 can be set as an inclined surface with a different inclination angle than the first guide surface 6.

[0038] like Figure 1-3As shown, in the swing structure provided in this embodiment, the housing 1 has an installation groove 2 inside, the width of which is the same as the width of the air outlet. The installation groove 2 forms an air supply channel extending towards the interior of the housing 1. The guide member 3 is vertically and flexibly disposed within the installation groove 2. The installation groove 2 forms an air supply channel on the housing 1 with the same width as the air outlet, guiding the air supply. The guide member 3 moves up and down along the air supply channel within the installation groove 2, changing the air outlet direction and achieving a swing effect. Specifically, the installation groove 2 and the housing 1 can be configured as two detachable and assembleable parts, or as an integral structure, depending on design requirements. Alternatively, as an alternative implementation, the installation groove 2 can be omitted, and the air supply channel can be directly formed inside the housing 1.

[0039] like Figure 1-3 As shown, in the swing structure provided in this embodiment, an installation space is formed between the mounting groove 2 and the housing 1. A lifting mechanism 5 is provided on the outer wall of the mounting groove 2. The lifting mechanism 5 is located within the installation space, and its drive end is connected to the guide member 3. The lifting mechanism 5, located in the installation space between the mounting groove 2 and the housing 1, does not occupy the space of the air supply channel, reducing the space occupied by the lifting mechanism 5 at the air outlet. This allows the swing structure to be applied to extremely narrow air outlets. Alternatively, as an alternative implementation, the lifting mechanism 5 can also be installed on the main body of the bathroom heater / ventilation unit.

[0040] like Figure 3-5 As shown, in the swing structure provided in this embodiment, the lifting mechanism 5 includes a drive device 8 and a transmission assembly. The drive device 8 is fixedly mounted on the outer wall of the mounting groove 2; the transmission assembly is the drive end of the drive device 8 and is connected to the guide member 3. The drive device 8 drives the guide member 3 to move up and down along the mounting groove 2 through the transmission assembly, which allows the drive device 8 to move away from the air outlet, reducing the space occupied at the air outlet, thus making it suitable for extremely narrow air outlets. Specifically, the drive device 8 is a stepper motor. Alternatively, as an alternative implementation, the transmission assembly can be omitted, and the drive device 8 can be an electric push rod or other linear drive device 8.

[0041] like Figure 3 , Figure 4As shown, in the swing structure provided in this embodiment, the transmission component includes a turntable 9 and a rope. The turntable 9 is disposed at the driving end of the driving device 8, and the driving device 8 drives the turntable 9 to rotate. The rope is wound around the turntable 9, and the end of the rope is connected to the guide member 3. The driving device 8 drives the turntable 9 to rotate, and the turntable 9 winds up and unwinds the rope, thereby realizing the lifting and lowering movement of the guide member 3. Alternatively, as an alternative implementation, the transmission component can also be configured as a screw drive structure or other linear drive structure.

[0042] like Figure 3 , Figure 5 As shown, in the swing structure provided in this embodiment, at least two fixing posts 10 are provided on the outer wall of the mounting groove 2, and at least two fixing plates 11 are provided on the driving device 8. The fixing plates 11 are fixedly connected to the fixing posts 10. The fixing posts 10 provide a space for the turntable 9 to be installed between the driving device 8 and the outer wall of the mounting groove 2. The side wall of the mounting groove 2 blocks the driving end of the driving device 8, preventing the turntable 9 from falling off the driving end of the driving device 8. Specifically, the fixing plates 11 and the fixing posts 10 are fixedly connected by fasteners. Alternatively, as an alternative embodiment, the fixing posts 10 can be omitted, and the driving shaft of the driving device 8 extends in a direction away from the mounting groove 2.

[0043] like Figure 3 As shown, in the swing structure provided in this embodiment, one lifting mechanism 5 is provided at each end of the mounting groove 2. The two lifting mechanisms 5 drive the guide member 3 to rise and fall from both ends, which makes the rising and falling movement of the guide member 3 more stable. In addition, as an alternative implementation, one or more lifting mechanisms 5 can be provided as needed.

[0044] like Figure 3 , Figure 6 As shown, in the swing structure provided in this embodiment, a guide groove 13 is provided on the side wall of the mounting groove 2, and a guide post 12 is provided on the guide member 3. The guide post 12 is slidably disposed within the guide groove 13. The guide groove 13 serves to guide and limit the guide post 12, that is, to guide and limit the lifting and lowering movement of the guide member 3, thereby preventing swaying during the lifting and lowering movement of the guide member 3. Alternatively, as an alternative embodiment, the guide groove 13 can be disposed on the guide member 3, and the guide post 12 can be disposed on the side wall of the mounting groove 2.

[0045] How to use:

[0046] like Figure 1 , Figure 2 As shown, in this embodiment, the swing structure is used such that the lifting mechanism 5 drives the guide member 3 to move up and down along the mounting groove 2. When the guide member 3 is in the first position, the air delivered to the air outlet by the air supply channel will change from vertically downward to obliquely outward along the first guide surface 6 under the guidance of the first guide surface 6. When the guide member 3 is in the second position, the air delivered to the air outlet by the air supply channel will be vertically downward under the guidance of the second guide surface 7. As the guide member 3 moves up and down, the air outlet direction changes, thus achieving the swing effect.

[0047] In addition, this embodiment also provides a bathroom heater, including a main body and a swing structure as described in any of the above solutions, wherein the swing structure is disposed at the air outlet end of the main body. By employing the swing structure described in the above embodiments, the swing effect of the bathroom heater is achieved.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
