Description

Technical Field

[0001] This invention relates to the technical field of home appliances, and more specifically, to a bathroom heater structure and its control method. Background Technology

[0002] Currently, ordinary bathroom heater covers on the market, in addition to their decorative appearance, also have air inlet and outlet channels. They guide indoor air through the air inlet to the main unit's air duct and guide the air blown out by the main unit into the room. In addition, they can also provide lighting by installing panel lights or light strips on the cover.

[0003] However, this type of ordinary bathroom heater cover has the following problems: many holes or several thin air guide strips will be added to the front of the cover. This not only destroys the overall appearance, but also greatly reduces the decorative effect that the cover is meant to provide. Furthermore, it cannot seal the entire product, and cannot prevent indoor flying insects or water vapor from entering the main unit through the holes, coming into contact with live parts, and thus causing safety hazards, affecting the product's lifespan and user experience.

[0004] Some masks on the market are made with a double-layer structure, using a four-sided air intake to reduce front openings and improve aesthetics. However, they also leave air intake holes in the indoor part, which cannot prevent indoor dust and moisture from entering the main unit through the four-sided air intakes. Furthermore, the mask protrudes from the ceiling surface, ruining the overall look.

[0005] As can be seen from the above, the current bathroom heaters have the problem of poor sealing due to the air inlet and outlet on the face shield disrupting the overall integrity. Summary of the Invention

[0006] The main objective of this invention is to provide a bathroom heater structure and its control method to solve the problem of poor sealing caused by the air inlet and outlet on the faceplate of existing bathroom heaters, which disrupts the overall integrity of the heater.

[0007] To achieve the above objectives, according to one aspect of the present invention, a bathroom heater structure is provided. The bathroom heater structure includes a main unit with a receiving groove; a mask body movably mounted on the main unit, with a mask air inlet and a mask air outlet provided on its peripheral sidewalls; the mask body has a ventilated state and a closed state; when the mask body is in the closed state, it covers the receiving groove and forms a closed area, with the mask air inlet and outlet hidden inside the closed area; when the mask body switches to the ventilated state, it moves away from the main unit, exposing the mask air inlet and outlet outside the receiving groove.

[0008] Furthermore, the mask body has a base plate and a surrounding plate. The surrounding plate is set on the mounting surface of the base plate facing the bottom of the receiving groove. The surrounding plate extends circumferentially along the base plate. The base plate and the surrounding plate cooperate to form a groove structure.

[0014] Furthermore, the fan is installed in the central area of ​​the bottom surface of the receiving trough, the fan inlet is located on the end face of the fan facing the mask body, and the fan outlet is located on the peripheral side wall of the fan with its opening facing the peripheral side wall of the receiving trough.

[0015] Furthermore, the bathroom heater structure also includes an air duct assembly including a first air duct and a second air duct. The first end of the first air duct is connected to the mask body and communicates with the mask air outlet. The first end of the second air duct is connected to the fan and communicates with the fan air outlet. The second end of the first air duct is connected to the second end of the second air duct and is slidably connected. The first air duct and the second air duct form a ventilation air duct.

[0016] Furthermore, the second end of the second air duct extends into the interior of the first air duct from the second end of the first air duct, and a circumferential flange is provided at the opening of the second end of the first air duct, with the inner wall surface of the circumferential flange slidingly connected to the outer wall surface of the second air duct; or the second end of the first air duct extends into the interior of the second air duct from the second end of the second air duct, with a circumferential flange provided at the second end of the second air duct, and the inner wall surface of the circumferential flange slidingly connected to the outer wall surface of the first air duct.

[0017] Furthermore, the mask body is provided with a first limiting member and a second limiting member arranged circumferentially along the surrounding plate. The distance between the first limiting member and the base plate is less than the distance between the second limiting member and the base plate. The main unit has a third limiting member. When the mask body is in a closed state, the end faces of the first limiting member and the third limiting member facing the opening of the receiving groove abut against each other. When the mask body is in a ventilated state, the end faces of the second limiting member and the third limiting member facing away from the opening of the receiving groove abut against each other.

[0018] Furthermore, the main unit includes a housing and a mounting frame installed at the open end of the housing. The opening on the side of the mounting frame away from the housing forms a groove for receiving a slot. A third limiting member extending circumferentially is provided on the inner wall surface of the mounting frame. The third limiting member and the groove of the receiving slot are spaced apart in the vertical direction. When the mask body is in a closed state, the end face of the mask body away from the bottom of the receiving slot is flush with the end face of the mounting frame away from the bottom of the receiving slot.

[0019] Furthermore, along the height direction of the enclosure, the mask air inlet and mask air outlet are located in the area between the first limiting member and the second limiting member.

[0020] Furthermore, the bathroom heater structure also includes a drive component, which is installed inside the receiving groove; and a transmission component, which is installed on the mask body and extends toward the inside of the receiving groove. The drive component is driven to connect with the transmission component, and the drive component provides driving force for the mask body to move toward or away from the main unit.

[0021] Furthermore, the bathroom heater structure also includes a heater, which is disposed inside the first air duct and / or the second air duct of the air duct assembly; and / or an air guide plate, which is movably installed at the air inlet and air outlet of the face mask.

[0022] According to another aspect of the present invention, a control method for a bathroom heater structure is provided, wherein the bathroom heater structure is as described above, and the control method for the bathroom heater structure includes at least an on mode and an off mode.

[0023] Depending on the different operation commands received, control the execution of the on or off mode;

[0024] When the activation mode is executed, the control panel of the bathroom heater structure switches to ventilation mode;

[0026] When the off mode is executed, the control panel of the bathroom heater structure switches to the closed state;

[0027] Control the shutdown of the fan and heater of the bathroom heater structure.

[0028] Furthermore, when the OFF mode is executed, the drive unit of the OFF mode controls the drive mask body to move in a direction away from the main unit of the OFF mode, so as to expose the mask air inlet and the mask air outlet; and positions the mask body and keeps it in a ventilated state; when the OFF mode is executed, the drive unit of the OFF mode receives a start signal, controls the drive mask body to move in a direction towards the main unit of the OFF mode, so as to hide the mask air inlet and the mask air outlet and position the mask body and keep it in a closed state.

[0029] According to the technical solution of this invention, the bathroom heater structure includes a main unit and a mask body. The main unit is provided with a receiving groove, and the mask body is movably mounted on the main unit. The peripheral sidewall of the mask body is provided with a mask air inlet and a mask air outlet. The mask body has a ventilated state and a closed state. When the mask body is in the closed state, the mask body covers the receiving groove and forms a closed area, and the mask air inlet and mask air outlet are hidden inside the closed area. When the mask body switches to the ventilated state, the mask body moves in a direction away from the main unit, and the mask air inlet and mask air outlet are exposed outside the receiving groove.

[0030] As can be seen from the above, the mask body of the bathroom heater structure of this application has a ventilated state and a closed state. By switching the state of the mask body, the air inlet and outlet of the mask can be hidden or exposed. When the air inlet and outlet of the mask are hidden inside the closed area, they cannot communicate with the outside, thus ensuring the overall integrity of the bathroom heater structure and the airtightness of the structure, preventing dust and flying insects from entering the interior of the bathroom heater structure. The air inlet and outlet of the mask are located on the periphery of the mask body, so that air enters and exits from the periphery of the mask body, avoiding the problem of vertical airflow blowing directly on the human body, thus improving the user experience.

[0044] Example 1

[0045] To address the problem of poor sealing caused by the air inlet and outlet on the faceplate of existing bathroom heaters disrupting the overall integrity, this invention provides a bathroom heater structure.

[0046] like Figures 1 to 5As shown, the bathroom heater structure includes a main unit 10 and a mask body 20. The main unit 10 is provided with a receiving groove 111. The mask body 20 is movably mounted on the main unit 10. The sidewalls of the mask body 20 are provided with a mask air inlet 221 and a mask air outlet 222. The mask body 20 has a ventilated state and a closed state. When the mask body 20 is in the closed state, the mask body 20 covers the receiving groove 111 and forms a closed area. The mask air inlet 221 and the mask air outlet 222 are hidden inside the closed area. When the mask body 20 switches to the ventilated state, the mask body 20 moves away from the main unit 10, and the mask air inlet 221 and the mask air outlet 222 are exposed outside the receiving groove 111.

[0047] Specifically, the mask body 20 of the bathroom heater structure of this application has a ventilated state and a closed state. By switching the state of the mask body 20, the mask air inlet 221 and the mask air outlet 222 can be hidden or exposed. When the mask air inlet 221 and the mask air outlet 222 are hidden inside the closed area, the mask air inlet 221 and the mask air outlet 222 cannot communicate with the outside world, so as to ensure the overall integrity of the bathroom heater structure and at the same time ensure the airtightness of the bathroom heater structure, and prevent the outside dust and flying insects from entering the interior of the bathroom heater structure.

[0048] Furthermore, the air inlet 221 and air outlet 222 of the mask are located on the periphery of the mask body 20, so that air enters and exits on the periphery of the mask body 20, thereby avoiding the problem of vertical airflow blowing directly on the human body and improving the user's experience.

[0049] Furthermore, the air inlet 221 of the mask is connected to the receiving groove 111 so that when the mask body 20 is in a ventilated state, the gas enters the interior of the receiving groove 111 from the outside through the air inlet 221 of the mask, and then flows back to the outside through the fan 30 and the heater 70.

[0050] In this embodiment, the mask body 20 has a base plate 210 and a surrounding plate 220. The surrounding plate 220 is disposed on the mounting surface of the base plate 210 facing the bottom of the receiving groove 111. The surrounding plate 220 extends circumferentially along the base plate 210. The base plate 210 and the surrounding plate 220 cooperate to form a groove structure. The mask air inlet 221 and the mask air outlet 222 are disposed on the surrounding plate 220.

[0051] The mounting surface of the base plate 210 facing the bottom of the receiving groove 111 is the first mounting surface, which is used to install the surrounding plate 220. The mounting surface of the base plate 210 away from the bottom of the receiving groove 111 is the second mounting surface, which is used to install the light source, which can be a light strip or other structure to achieve the lighting effect.

[0052] It should be noted that, depending on the area enclosed by the enclosure 220, the enclosure 220 can form a circular or polygonal groove structure.

[0053] Furthermore, multiple air inlets 221 are provided for the face mask, and the multiple air inlets 221 are spaced apart along the extension direction of the enclosure 220.

[0054] Of course, it is not limited to the case where there are multiple air inlets 221 on the mask. Depending on the structure of the mask body 20, there may also be only one air inlet 221 on the mask.

[0055] Furthermore, multiple air outlets 222 of the face mask are provided, and the multiple air outlets 222 of the face mask are spaced apart along the extension direction of the enclosure 220.

[0056] Of course, it is not limited to the case where there are multiple air outlets 222 on the mask. Depending on the structure of the mask body 20, there may also be only one air outlet 222 on the mask.

[0057] In this embodiment, the enclosure 220 has multiple segments connected in sequence, each segment is provided with a mask air inlet 221 and a mask air outlet 222. By providing a mask air inlet 221 and a mask air outlet 222 on each segment, multi-directional air intake and multi-directional air outlet are achieved, so that the airflow flows evenly and stably.

[0058] Furthermore, the air inlets 221 and outlets 222 of the face mask are staggered on each panel segment, and the air inlets 221 and outlets 222 of the face mask are arranged adjacent to each other. When there are multiple air inlets 221 and outlets 222 of the face mask on each panel segment, the outlets 222 of the face mask are arranged between two adjacent air inlets 221, and the air inlets 221 of the face mask are arranged between two adjacent outlets 222.

[0059] In one specific embodiment of this example, the enclosure 220 has a first plate segment, a second plate segment, a third plate segment and a fourth plate segment connected in sequence, wherein the first plate segment and the fourth plate segment are connected end to end to form a rectangular structure, and the first plate segment, the second plate segment, the third plate segment and the fourth plate segment have the same structure and are all provided with a mask air inlet 221 and a mask air outlet 222.

[0060] Taking the first panel segment as an example, the first panel segment may have one mask air inlet 221 and one mask air outlet 222; or the first panel segment may have two mask air inlets 221 and one mask air outlet 222, with the mask air outlet 222 located between the two mask air inlets 221; or the first panel segment may have three mask air inlets 221 and two mask air outlets 222, with the mask air outlet 222 located between the two mask air inlets 221.

[0061] like Figures 1 to 5 As shown, the bathroom heater structure also includes a fan 30 and an air duct assembly 40. The fan 30 is disposed inside the receiving groove 111. The fan 30 has a fan inlet 310 and at least one fan outlet 320. The fan inlet 310 and the mask inlet 221 are both connected to the receiving groove 111. The fan outlet 320 is connected to and corresponds to the mask outlet 222. The mask outlet 222 and the fan outlet 322 are connected through the air duct assembly 40. The air duct assembly 40 forms a ventilation duct that is isolated from the receiving groove 111.

[0062] Specifically, when the mask body 20 is in the closed state, the fan 30 does not work. When the mask body 20 is in the ventilation state, the fan 30 runs. When the fan 30 runs, the exposed mask air inlet 221 draws the outside air into the interior of the receiving groove 111 and enters the interior of the fan 30 through the fan air inlet 310. After passing through the fan 30 air outlet, the air flows into the interior of the ventilation duct and then flows out through the mask air outlet 222. The fan 30 provides driving force for the flow of gas.

[0063] Furthermore, the air duct assembly 40 includes a first air duct 410 and a second air duct 420. The first end of the first air duct 410 is connected to the mask body 20 and communicates with the mask air outlet 222. The first end of the second air duct 420 is connected to the fan 30 and communicates with the fan air outlet 320. The second end of the first air duct 410 and the second end of the second air duct 420 are connected and slidably connected. The first air duct 410 and the second air duct 420 form a ventilation air duct.

[0064] The second end of the first air duct 410 and the second end of the second air duct 420 are slidably connected so that when the mask body 20 moves to drive the first air duct 410 to move toward or away from the bottom of the receiving groove 111, the first air duct 410 and the second air duct 420 slide relative to each other but keep the ventilation duct isolated from the receiving cavity to ensure smooth gas flow.

[0065] In this embodiment, two different implementation methods are provided based on the different structures connecting the second end of the first air duct 410 and the second end of the second air duct 420.

[0066] like Figures 1 to 5 In the specific embodiment shown, the second end of the second air duct 420 passes through the second end of the first air duct 410 and extends into the interior of the first air duct 410. A circumferential flange 411 is provided at the opening of the second end of the first air duct 410, and the inner wall surface of the circumferential flange 411 is slidably connected to the outer wall surface of the second air duct 420.

[0067] Furthermore, a circumferential flange 411 is provided at the opening of the second end of the first air duct 410 to form an opening structure. The second end of the second air duct 420 extends into the interior of the first air duct 410 through the opening structure. The inner wall surface of the circumferential flange 411 is slidably connected to the outer wall surface of the second air duct 420 so as to realize that the first air duct 410 can slide with the second air duct 420.

[0068] In a specific embodiment not shown, the second end of the first air duct 410 passes through the second end of the second air duct 420 and extends into the interior of the second air duct 420. A circumferential flange is provided at the second end of the second air duct 420, and the inner wall surface of the circumferential flange is slidably connected to the outer wall surface of the first air duct 410.

[0069] Furthermore, a circumferential flange provided at the second end of the second air duct 420 forms an opening structure, through which the second end of the first air duct 410 passes and slides to connect with the outer wall of the first air duct 410 via the inner wall surface of the circumferential flange, so as to enable the first air duct 410 to slide with the second air duct 420.

[0070] In this embodiment, the fan 30 is installed in the central area of ​​the bottom surface of the receiving groove 111. The fan inlet 310 is located on the end face of the fan 30 facing the mask body 20, and the fan outlet 320 is located on the peripheral sidewall of the fan 30 with its opening facing the peripheral sidewall of the receiving groove 111. This allows the gas from the mask inlet 221 to enter the interior of the receiving groove 111. When the fan 30 is running, it can draw the gas inside the receiving groove 111 into the fan inlet 310. At the same time, the fan outlet 320, which is located facing the sidewall of the receiving groove 111, is located close to the mask outlet 222 to facilitate the sliding cooperation of the first air duct 410 and the second air duct 420.

[0071] like Figures 1 to 5 As shown, the mask body 20 is provided with a first limiting member 80 and a second limiting member 90 arranged circumferentially along the surrounding plate 220. The distance between the first limiting member 80 and the bottom plate 210 is less than the distance between the second limiting member 90 and the bottom plate 210. The main unit 10 includes a housing 110 and a mounting frame 120 installed at the opening end of the housing 110. The opening on the side of the mounting frame 120 away from the housing 110 forms a groove of the receiving groove 111. A third limiting member 100 extending circumferentially is provided on the inner wall surface of the mounting frame 120. The third limiting member 100 is spaced apart from the groove of the receiving groove 111.

[0072] Specifically, the distance between the first limiting member 80 and the base plate 210 is less than the distance between the second limiting member 90 and the base plate 210, so that a movable area is formed between the first limiting member 80 and the second limiting member 90, that is, the distance between the first limiting member 80 and the second limiting member 90 is the moving distance of the mask body 20.

[0073] Furthermore, when the mask body 20 is in the closed state, the first limiting member 80 and the third limiting member 100 abut against the end faces of the groove opening of the receiving groove 111 to achieve the limiting function. The end face of the mask body 20 away from the bottom of the receiving groove 111 is flush with the end face of the mounting frame 120 away from the bottom of the receiving groove 111, so that the mask body 20 and the host 10 are flat as a whole, improving the aesthetics.

[0074] Furthermore, when the mask body 20 is in a ventilated state, the second limiting member 90 and the third limiting member 100 abut against the end face of the groove opening of the receiving groove 111 to achieve the limiting effect and prevent the mask body 20 from falling off.

[0075] In this embodiment, along the height direction of the enclosure 220, i.e. the depth direction of the receiving groove 111, the mask air inlet 221 and the mask air outlet 222 are located in the area between the first limiting member 80 and the second limiting member 90, so that the mask air inlet 221 and the mask air outlet 222 can be hidden or exposed during the movement of the mask body 20.

[0076] like Figures 1 to 5 As shown, the structure of the bathroom heater of this application also includes a drive member 50 and a transmission member 60. The drive member 50 is installed inside the receiving groove 111, and the transmission member 60 is installed on the mask body 20 and extends toward the inside of the receiving groove 111. The drive member 50 and the transmission member 60 are drivenly connected. The drive member 50 provides driving force for the mask body 20 to move toward or away from the main unit 10.

[0077] Specifically, under the combined action of the drive component 50 and the transmission component 60, the mask body 20 can be raised and lowered so that the mask body 20 is in a ventilated state when it is raised and in a closed state when it is lowered.

[0078] Furthermore, the driving component 50 is a motor, and a gear is provided on the output shaft of the motor. The transmission component 60 is a rack provided on the mask body 20, and the rack meshes with the gear. The rack extends into the receiving groove 111. Under the output of the motor, the gear rotates to drive the rack to move up and down, thereby realizing the lifting and lowering movement of the mask body 20.

[0079] It should be noted that the bathroom heater structure also includes a controller and a power supply. The power supply is used to provide power, and the drive unit 50 and the fan 30 are connected to the controller via signals to determine whether to start the heater under the control of the controller.

[0080] In this embodiment, the bathroom heater structure also includes a heater 70. The heater 70 can be disposed inside the first air duct 410 of the air duct assembly 40, or inside the second air duct 420 of the air duct assembly 40. Alternatively, the heater 70 can be disposed inside both the first air duct 410 and the second air duct 420.

[0081] To adjust the airflow direction at the air inlet 221 and air outlet 222 of the face mask, the bathroom heater structure also includes an air guide plate. The air guide plate is movably installed at the air inlet 221 and air outlet 222 of the face mask, that is, the angle formed between the air guide plate and the base plate 210 is adjustable to achieve the adjustment of the airflow direction.

[0082] Furthermore, the air guide plate is a louver structure installed at the air inlet 221 and air outlet 222 of the mask.

[0083] Example 2

[0084] Unlike Embodiment 1, in this embodiment, the enclosure 220 has multiple sequentially connected plate segments, and each adjacent plate segment is provided with a mask air inlet 221 and a mask air outlet 222.

[0085] Specifically, a mask air inlet 221 is provided on one of the two adjacent plate segments, and a mask air outlet 222 is provided on the other plate segment, so that the airflow between the mask air inlet 221 and the mask air outlet 222 will not be disturbed under the drive of the fan 30.

[0086] In one specific embodiment of this example, the enclosure 220 has a first plate segment, a second plate segment, a third plate segment and a fourth plate segment connected in sequence, wherein the first plate segment and the fourth plate segment are connected end to end to form a rectangular structure, and one of a mask air inlet 221 and a mask air outlet 222 is provided on the first plate segment and the third plate segment, and the other of a mask air inlet 221 and a mask air outlet 222 is provided on the second plate segment and the fourth plate segment.

[0087] Example 3

[0088] Unlike Example 1, as Figure 6 As shown, in this embodiment, the enclosure 220 has multiple segments connected in sequence, one of which is provided with a mask air outlet 222, and the other segments are provided with mask air inlets 221.

[0089] Specifically, one of the plate segments is provided with a mask air outlet 222, and the other plate segments are provided with mask air inlets 221, so as to isolate the mask air inlets 221 and mask air outlets 222 to avoid airflow crossover and airflow interference.

[0090] In one specific embodiment of this example, the enclosure 220 has a first plate segment, a second plate segment, a third plate segment and a fourth plate segment connected in sequence, wherein the first plate segment and the fourth plate segment are connected end to end to form a rectangular structure, one of the first plate segment, the second plate segment, the third plate segment and the fourth plate segment is provided with a mask air outlet 222, and the other three are provided with mask air inlets 221.

[0091] Example 4

[0092] This embodiment provides a control method for a bathroom heater structure, such as... Figure 7 As shown, the bathroom heater structure is any one of the bathroom heater structures in Embodiments 1 to 3, and the control method of the bathroom heater structure includes at least an on mode and an off mode.

[0093] Depending on the different operation commands received, execute either the on mode or the off mode;

[0094] When the activation mode is executed, the face shield body 20 of the bathroom heater structure switches to the ventilation state;

[0095] Start the fan 30 and heater 70 of the bathroom heater structure;

[0096] When the off mode is executed, the face shield body 20 of the bathroom heater structure switches to the closed state;

[0097] Turn off the fan 30 and heater 70 of the bathroom heater structure.

[0098] Specifically, the mask body 20 has a ventilated state and a closed state. When the mask body 20 is in the closed state, the mask body 20 is controlled to cover the receiving groove 111 and form a closed area, with the mask air inlet 221 and mask air outlet 222 hidden inside the closed area. When the mask body 20 is switched to the ventilated state, the mask body 20 is controlled to move in a direction away from the host 10, with the mask air inlet 221 and mask air outlet 222 exposed outside the receiving groove 111.

[0099] Furthermore, when the mask body 20 is in the closed state, the end faces of the first limiting member 80 and the third limiting member 100 facing the opening of the receiving groove 111 are controlled to abut, and the end face of the mask body 20 away from the bottom of the receiving groove 111 is controlled to be flush with the end face of the mounting frame 120 away from the bottom of the receiving groove 111; when the mask body 20 is in the ventilated state, the end faces of the second limiting member 90 and the third limiting member 100 away from the opening of the receiving groove 111 are controlled to abut.

[0100] Furthermore, the operation instructions include open and close instructions. When an open instruction signal is received, the open mode is executed; when a close instruction signal is received, the close mode is executed.

[0101] In this embodiment, the operation command can be connected to the controller signal through an external terminal device to control whether the drive unit 50, heater 70 and fan 30 are running.

[0102] Furthermore, when executing the enabled mode,

[0103] The drive unit 50 of the bathroom heater structure receives the start signal and starts;

[0104] The drive unit 50 drives the mask body 20 to move in the direction away from the main unit 10 of the bathroom heater structure, so as to expose the mask air inlet 221 and the mask air outlet 222.

[0105] The drive unit 50 stops operating so that the mask body 20 is positioned and kept in a ventilated state.

[0106] The operation command sends a start signal to the drive unit 50 through the controller. When the second limit member 90 and the third limit member 100 come into contact, the controller controls the drive unit 50 to stop moving. Under the self-locking effect of the drive unit 50, the mask body 20 is positioned and maintained in the ventilation state.

[0107] Furthermore, when executing the shutdown mode,

[0108] The drive unit 50 of the bathroom heater structure receives the start signal and starts;

[0109] The driving component 50 drives the mask body 20 to move toward the main unit 10 of the bathroom heater structure to hide the mask air inlet 221 and the mask air outlet 222.

[0110] The drive unit 50 stops operating so that the mask body 20 is positioned and held in the closed state.

[0111] The operation command sends a start signal to the drive unit 50 through the controller. When the first limit member 80 and the third limit member 100 come into contact, the controller controls the drive unit 50 to stop moving. Under the self-locking effect of the drive unit 50, the mask body 20 is positioned and kept in the closed state.

[0112] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0113] 1. The face mask body 20 of the bathroom heater structure of this application has a ventilated state and a closed state. By switching the state of the face mask body 20, the face mask air inlet 221 and face mask air outlet 222 can be hidden or exposed. When the face mask air inlet 221 and face mask air outlet 222 are hidden inside the closed area, the face mask air inlet 221 and face mask air outlet 222 cannot communicate with the outside world, so as to ensure the overall integrity of the bathroom heater structure and at the same time ensure the airtightness of the bathroom heater structure, and prevent the phenomenon of external dust and flying insects entering the interior of the bathroom heater structure.

[0114] 2. The air inlet 221 and air outlet 222 of the mask are located on the periphery of the mask body 20, so that air enters and exits on the periphery of the mask body 20, thereby avoiding the problem of vertical airflow blowing directly on the human body and improving the user's experience.
