Description

Technical Field

[0001] This utility model relates to the field of bathroom heater panel technology, and in particular to a wind guide structure for a bathroom heater panel. Background Technology

[0002] Modern bathroom heaters typically have a heating element that blows out warm air to quickly raise the temperature in the bathroom, making people feel warm and comfortable while showering. Existing bathroom heaters usually have a louver installed under the heating element to control the direction of the warm air.

[0003] When using the heating device of a bathroom heater, the warm air diffuses to the surroundings, resulting in some heat loss. This can also cause the warm air to heat up the motor, causing it to overheat. Prolonged use of this device can reduce the lifespan of the motor or damage the motor and other components of the bathroom heater, ultimately leading to its failure. Utility Model Content

[0004] The main purpose of this utility model is to propose an air guiding structure for a bathroom heater panel, which aims to solve the technical problem in the prior art where the diffusion of warm air from a bathroom heater causes the motor temperature to be too high and damages the motor.

[0005] To achieve the above objectives, this utility model proposes an air guiding structure for a bathroom heater panel, comprising: a housing and a panel. The housing is equipped with a heating device, and the panel is located below the housing. The panel has an air outlet directly facing the lower part of the heating device. A fixed air guide frame is provided above the air outlet. The fixed air guide frame has a hollow internal structure, and its surrounding walls extend upwards. The fixed air guide frame can abut against the heating device and guide the warm air blown by the heating device out of the air outlet. A hinge is provided inside the fixed air guide frame, and the hinge is rotatably connected to the fixed air guide frame.

[0006] The panel has an air outlet, and a fixed air guide is installed above the air outlet so that the warm air blown out by the heating device can be blown out of the air outlet along the fixed air guide. Inside the fixed air guide is a swivel, and the swing of the swivel can control the direction of the warm air. The fixed air guide rests against the heating device to prevent the warm air blown out and returned by the heating device from spreading to the surroundings, thus protecting the motor and components near the air outlet.

[0007] Preferably, the flap includes an upper plate, a lower plate, multiple support plates, a first mounting shaft, and a second mounting shaft. The upper plate and the lower plate extend in the front-rear direction, with the upper plate positioned above the lower plate. The upper plate and the lower plate are arranged parallel to each other, forming a lateral cavity between them. The multiple support plates abut against the upper plate and the lower plate, providing support for both. When the flap is closed, the lower plate covers the air outlet. The first mounting shaft is located on the rear side of the flap and rotatably connected to the rear side of the fixed air guide frame. The second mounting shaft is located on the front side of the flap and rotatably connected to the front side of the fixed air guide frame, allowing the flap to be rotatably connected to the interior of the fixed air guide frame.

[0008] A cavity is formed between the upper and lower plates, making the airflow direction of the oscillating blade more accurate. Multiple support plates are set in the cavity to support the upper and lower plates, so that the oscillating blade will not be deformed due to thermal expansion and contraction after long-term use, ensuring the stability and durability of the oscillating blade. The design of two mounting shafts at the front and rear can ensure the balance of the oscillating blade during rotation, avoiding unstable oscillation caused by single-point support.

[0009] Preferably, the fixed air guide frame is rotatably connected to the two swing blades inside.

[0010] The design of two louvers allows for a wider air delivery angle and more flexible adjustment of the airflow direction.

[0011] Preferably, the air outlet, the interior of the fixed air guide frame, and the heating device are rectangular and of the same size. The front, left, and right walls of the fixed air guide frame extend upwards and can abut against the perimeter of the heating device. The front and rear sides of the fixed air guide frame are provided with mounting holes, which can be engaged with the first mounting shaft and the second mounting shaft. Both the first mounting shaft and the second mounting shaft are cylindrical.

[0012] The air outlet, the interior of the fixed air guide frame, and the heating device are the same size, so that the warm air blown out by the heating device flows out of the air outlet, reducing warm air backflow and avoiding damage to the internal circuitry of the cabinet. The first and second mounting shafts are both cylindrical, which facilitates the installation and rotation of the flaps.

[0013] Preferably, a motor is provided above the panel, and the motor is connected to the swing blade through a connecting rod. The motor can drive the swing blade to swing. A control system is provided on the panel and is connected to the motor. The control system can control the motor to rotate, thereby driving the swing blade to swing. The swing blade can adjust the airflow direction of the heating device.

[0014] The swinging of the page is controlled by a motor, which is connected to the control system. The swinging of the page can be achieved through the control system, which is convenient for users. A connecting rod is used to facilitate the motor control of the page rotation.

[0015] Preferably, the motor is provided with a rocker arm, the motor is driven to the rocker arm, the rocker arm is driven to the connecting rod, and the motor can drive the connecting rod to swing through the rocker arm.

[0016] The rocker arm can be used to transmit force when the motor rotates, converting the motor's rotation into pendulum motion, which in turn drives the pendulum to swing through the connecting rod.

[0017] Preferably, the rear side of the swing page is provided with a swing shaft, and the connecting rod is provided with a plurality of swing holes. The swing holes are respectively engaged with the swing shaft and the rocker arm, so that the rocker arm can drive the swing page to swing through the connecting rod.

[0018] The locking mechanism between the swing shaft, rocker arm, and connecting rod makes it easier to transmit the force of the motor rotation to the swing blades and facilitates parts replacement.

[0019] Preferably, a motor cover is provided above the motor.

[0020] The motor cover is placed on top of the motor and motor bracket to secure the motor and prevent it from being damaged by moisture and warm air.

[0021] Beneficial effects: The fixed air guide frame of this utility model can guide the warm air of the heating device to blow out from the air outlet, reduce backflow, and prevent the warm air from spreading around and damaging the internal components. The use of double swing blades can achieve a wider air delivery angle and facilitate air direction adjustment. Attached Figure Description

[0033] like Figure 1-5 As shown, a bathroom heater panel has an air guiding structure, including a housing 1 and a panel 2. The housing 1 is equipped with a heating device 11, and the panel 2 is located below the housing 1. The panel 2 is equipped with an air outlet 21, which faces the lower part of the heating device 11. A fixed air guide frame 3 is provided above the air outlet 21. The interior of the fixed air guide frame 33 is a hollow structure, and the surrounding wall of the fixed air guide frame 3 extends upward. The fixed air guide frame 3 can abut against the heating device 11 and guide the warm air blown out by the heating device 11 from the air outlet 21. The fixed air guide frame 3 is equipped with a hinge 31 inside, which is rotatably connected to the fixed air guide frame 3.

[0034] The panel 2 is provided with an air outlet 21, and a fixed air guide 3 is provided above the air outlet 21 so that the warm air blown out by the heating device 11 can be blown out from the air outlet 21 along the fixed air guide 3. A swivel 31 is installed inside the fixed air guide 33. The rotation of the swivel 31 can control the direction of the warm air. The wall of the fixed air guide 3 is pressed against the heating device 11 so that the warm air blown out and returned by the heating device 11 will not spread to the surroundings, protecting the motor 4 and components near the air outlet 21.

[0035] The air outlet 21 is located on the left side of the panel 2. The heating device 11 is installed inside the housing 1. The panel 2 can be fastened to the housing 1 of the bathroom heater so that the air outlet 21 is directly below the heating device 11, which facilitates the air output of the heating device 11. The fixed air guide 3 has a through hole around it and a corresponding protruding channel around the air outlet 21. The fixed air guide 3 is fixed above the air outlet 21 through the through hole and the channel, so that the fixed air guide 3 is located between the heating device 11 and the air outlet 21. The fixed air guide 3 can abut against the heating device 11. When the heating device 11 outputs air, the warm air can be blown out from the air outlet 21 through the fixed air guide 3. The fixed air guide 31 has a swaying blade inside the fixed air guide 3. The direction of the warm air is changed by the swinging of the swaying blade 31.

[0036] Furthermore, the fixed air guide frame 3 can be made of materials such as polystyrene and polyurethane to insulate against warm air and high temperature, thereby protecting components such as the motor 4 from the warm air.

[0037] like Figure 1As shown, in a specific embodiment, the flap 31 includes an upper plate 311, a lower plate 312, multiple support plates 313, a first mounting shaft 314, and a second mounting shaft 315. The upper plate 311 and the lower plate 312 extend in the front-rear direction, with the upper plate 311 positioned above the lower plate 312. The upper plate 311 and the lower plate 312 are arranged in parallel, forming a cavity in the left-right direction between them. The multiple support plates 313 abut against the upper plate 311 and the lower plate 312, providing support for the upper plate 311 and the lower plate 312. When the flap 31 is closed, the lower plate 312 covers the air outlet 21. The first mounting shaft 314 is rotatably connected to the rear side of the fixed air guide frame 3, and the second mounting shaft 315 is rotatably connected to the front side of the fixed air guide frame 3, so that the flap 31 is rotatably connected to the interior of the fixed air guide frame 3.

[0038] A cavity is formed between the upper plate 311 and the lower plate 312, making the airflow direction of the oscillating blade 31 more accurate. Multiple support plates 313 are set in the cavity to support the upper plate 311 and the lower plate 312, so that the oscillating blade 31 will not be deformed due to thermal expansion and contraction after long-term use, ensuring the stability and durability of the oscillating blade 31. The design of two mounting shafts at the front and rear can ensure the balance of the oscillating blade 31 during rotation and avoid unstable swaying caused by single-point support.

[0039] The upper plate 311 and the lower plate 312 extend in the front-to-back direction, and the left-to-right width of the upper plate 311 is smaller than that of the lower plate 312. The support plate 313 is trapezoidal with a narrow top and a wide bottom. Four support plates 313 vertically support the upper plate 311 and the lower plate 312. Two of the support plates 313 are located at the front and rear ends of the upper plate 311 and the lower plate 312. The first mounting shaft 314 and the second mounting shaft 315 are respectively installed on the support plates 313 at the front and rear ends. The upper side length of the support plate 313 is the same as the left-to-right width of the upper plate 311, so that the oscillating blade 31 forms a structure that is narrow at the top and wide at the bottom, which facilitates the smooth flow of warm air and provides a suitable area for blowing air. When the oscillating blade 31 is not in use, the lower plate 312 covers the air outlet 21 to prevent dust from entering. When the oscillating blade 31 swings, it can swing with the front and rear mounting shafts as fulcrums to ensure balance and the stability of the airflow direction.

[0040] In a specific embodiment, the interior 33 of the fixed air guide frame is rotatably connected to the two swing blades 31.

[0041] The design of two flaps 31 allows for a wider air delivery angle and more flexible adjustment of the airflow direction.

[0042] Two flaps 31 are arranged sequentially in the left and right direction inside the fixed air guide frame 3. When the flaps 31 are closed, the two lower plates 312 can cover the air outlet 21 to block dust. The two flaps 31 can adjust the ventilation of the two cavities, making the airflow more precise.

[0043] like Figure 2 As shown, in a specific embodiment, the interior 33 of the fixed air guide frame and the heating device 11 are rectangular and of the same size. The front, left and right walls of the fixed air guide frame 3 extend upward and can abut against the perimeter of the heating device 11. The front and rear sides of the fixed air guide frame 3 are provided with mounting holes, which can be engaged with the first mounting shaft 314 and the second mounting shaft 315. Both the first mounting shaft 314 and the second mounting shaft 315 are cylindrical.

[0044] The air outlet 21, the fixed air guide frame 3 and the heating device 11 are the same size, so that the warm air blown out by the heating device 11 flows out from the air outlet 21, reducing the backflow of warm air and avoiding damage to the internal circuit of the housing 1 by the warm air. The first mounting shaft 314 and the second mounting shaft 315 are both cylindrical, which can facilitate the installation and rotation of the swing blade 31.

[0045] The heating device 11 is located on the left side of the housing 1. The right side of the housing 1 can be used to place a heater and a cooler for ventilation. The air outlet 21 below the heating device 11 is located on the left side of the panel 2. The right side of the panel 2 can be used to place an LED panel 2 light for illumination. The fixed air guide 3 covers the heating device 11 and contains the warm air blown out by the heating device 11. The three side walls of the fixed air guide 3 abut against the front, left and right sides of the warm air. The front and rear sides of the fixed air guide 3 are provided with mounting holes, which can be used to snap the first mounting shaft 314 and the second mounting shaft 315. The rear side of the fixed air guide 3 has a notch, which makes it easy to install the flap 31 into the fixed air guide 3.

[0046] like Figure 2-3 As shown, in one embodiment, a motor 4 is provided above the panel 2. The motor 4 and the swing blade 31 are connected by a connecting rod 5, so that the motor 4 can drive the swing blade 31 to swing by driving the connecting rod 5. A control system is provided on the panel 2. The control system is connected to the motor 4. The control system can control the motor 4 to rotate, thereby driving the swing blade 31 to swing. The swing blade 31 can adjust the airflow direction of the heating device 11.

[0047] Motor 4 is used to control the swing of the page 31, and motor 4 is connected to the control system. The swing of the page 31 can be realized through the control system, which is convenient for users. The connecting rod 5 is used to facilitate the motor 4 to control the rotation of the page 31.

[0048] The control system is divided into a digital display control panel 222 and a digital display circuit board 23. The digital display control panel 222 is located below the panel 2, between the air outlet 21 and the light on the panel 2. The digital display circuit board 23 is located above the panel 2 and is connected to the digital display control board. Clicking the digital display control panel 222 controls the digital display circuit board 23, which in turn controls the operation of the bathroom heater. The digital display control panel 2 includes buttons for temperature display, power switch, swing function, air volume control, temperature control, and lighting. Clicking the corresponding button produces different effects for the bathroom heater.

[0049] Furthermore, a bracket for motor 4 is installed above motor 4.

[0050] The motor 4 bracket can fix the motor 4 to the panel 2 to prevent the motor 4 from falling off when it moves.

[0051] In a specific embodiment, the motor 4 is provided with a rocker arm 41, the motor 4 is connected to the rocker arm 41 in a transmission connection, the rocker arm 41 is connected to the connecting rod 5 in a transmission connection, and the motor 4 can drive the connecting rod 5 to swing through the rocker arm 41.

[0052] The rocker arm 41 can be used as a force transmitter when the motor 4 rotates, so that the rotation of the motor 4 is converted into pendulum motion, which in turn drives the pendulum 31 to swing through the connecting rod 5.

[0053] The motor 4 used is a stepper motor 4. When the stepper motor 4 is controlled to rotate by the control system, the rocker arm 41 mounted on the rotating rod of the motor 4 rotates at the same time. Because the rod part on the rocker arm 41 causes the rocker arm 41 to make a pendulum motion, it drives the connecting rod 5 to make a pendulum motion. Then the connecting rod 5 drives the pendulum 31 to swing to change the wind direction.

[0054] In one embodiment, a swing shaft 316 is provided on the rear side of the swing page 31, and a plurality of swing holes are provided on the connecting rod 5. The swing holes are respectively engaged with the swing shaft 316 and the rocker arm 41, so that the rocker arm 41 can drive the swing page 31 to swing through the connecting rod 5.

[0055] The engagement of the swing shaft 316, rocker arm 41, and connecting rod 5 makes it easier for the force of the motor 4 to be transmitted to the swing blade 31, and also facilitates the replacement of parts.

[0056] The swing shaft 316 and rocker arm 41 are provided with annular grooves so that the swing shaft 316 and rocker arm 41 can be engaged in the swing hole. Each of the two swing blades 31 has a swing shaft 316 on the rear support plate 313. The connecting rod 5 is rectangular and has three swing holes on its surface. The two swing shafts 316 and rocker arm 41 are engaged in the swing holes so that the rocker arm 41 can simultaneously and stably drive the two swing shafts 316 to swing, thereby driving the swing blades 31 to swing.

[0057] like Figure 4As shown, in a specific embodiment, a motor cover 42 is provided above the motor 4.

[0058] The motor cover 42 is fastened above the motor 4 and the motor 4 bracket, which can fix the motor 4 and prevent the motor 4 and the control system from being damaged by moisture and warm air.

[0059] The motor 4 is located on the right side of the fixed air guide frame 3. The motor 4 is fixed above the panel 2 using the motor 4 bracket. The digital display circuit board 23 is located in front of the motor 4. The motor cover 42 can cover both the motor 4 and the digital display circuit board 23 at the same time, thereby protecting the motor 4 and the control system. The right side wall of the fixed air guide frame 3 can block the warm air to prevent baking the motor 4 and the digital display circuit board 23.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
