Description

Technical Field

[0001] This utility model specifically relates to a bathroom heater. Background Technology

[0002] A bathroom heater is a device used to provide heating during showers in cold weather. It is typically mounted on the bathroom ceiling. Existing bathroom heaters are quite thick, taking up considerable space and requiring the ceiling installation position to be lowered, reducing bathroom space. Furthermore, the increased thickness of the heater also raises production costs, reducing business profits. Therefore, it is necessary to provide a bathroom heater that, through structural improvements, achieves a thinner design without compromising its efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a bathroom heater that solves the shortcomings of existing bathroom heaters, which are thick and occupy a lot of ceiling installation space.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] A bathroom heater, characterized in that it includes a housing, the housing having an air outlet assembly having a first air inlet and a first air outlet; it also includes a blower volute disposed within the housing, the blower volute having a second air inlet and a second air outlet, the second air outlet of the blower volute being connected to the first air inlet of the air outlet assembly via a first air guide channel, such that the vertical height of the first air inlet of the air outlet assembly is lower than the vertical height of the second air outlet of the blower volute; a guide element is connected to the first air inlet of the air outlet assembly.

[0006] In this invention, the first air inlet of the air outlet component is located on the side wall of the air outlet component, and the first air outlet of the air outlet component is located on the top of the air outlet component.

[0007] Furthermore, a heater is fixedly connected to the first air outlet of the air outlet assembly.

[0008] In this invention, the air guide is fixed to the top of the first air inlet of the air outlet assembly. The air guide, positioned at the top of the first air inlet, effectively utilizes the space created by lowering the height of the air outlet assembly, while simultaneously guiding airflow from the air inlet to the air outlet assembly more effectively, ensuring sufficient airflow intensity.

[0009] Furthermore, the flow guide is a wedge-shaped flow guide plate.

[0010] Furthermore, the wedge-shaped guide plate has an angle of 30-60 degrees with the horizontal plane.

[0011] Furthermore, the windward surface of the wedge-shaped guide plate is configured as a concave arc-shaped surface.

[0012] In this utility model, the first air guide channel is formed by sequentially connecting and enclosing a first sidewall, a second sidewall, a casing sidewall, a third sidewall, and a fourth sidewall.

[0013] Furthermore, the first rim surrounds the blower housing, and the height of the first rim is approximately equal to the height of the blower housing; the height of the second rim is lower than the height of the first rim, and the heights of the third and fourth rims are also lower than the height of the first rim; the air outlet assembly is fixed to the second, third, and fourth rims. By reducing the height of the second, third, and fourth rims of the air outlet assembly fixing piece, the overall height of the air outlet assembly is reduced, thereby reducing the overall height of the bathroom heater.

[0014] In this invention, the housing is further provided with an exhaust port, and the second air outlet of the blower volute is connected to the exhaust port through a first air guide channel and a second air guide channel. With this arrangement, the first air guide channel can be used for both heating and ventilation, improving the utilization rate of the bathroom heater's internal space, reducing its overall size, and minimizing the space occupied by the bathroom heater when installed on the ceiling.

[0015] Furthermore, the first air guide channel and the second air guide channel are connected by a third air inlet, which is located on the first perimeter.

[0016] Furthermore, the second air guide channel is formed by the fourth enclosure, the casing side wall, and the fifth enclosure connected in sequence.

[0017] In some embodiments of this utility model, an air inlet switching component is also included. The air inlet switching component includes a motor and a baffle. The baffle is fixed on the output shaft of the motor, so that the motor drives the baffle to close the first air inlet or the third air inlet.

[0018] This utility model has the following beneficial effects:

[0019] (1) The present invention provides a guide at the air outlet of the air outlet component of the bathroom heater and reduces the height of the air outlet component relative to the blower volute. This can reduce the thickness of the entire bathroom heater while ensuring the original air outlet efficiency of the bathroom heater, reduce the space occupied by the bathroom heater, and free up more space for the installation of the bathroom heater in the ceiling.

[0020] (2) The present invention’s bathroom heater can switch between heating and exhaust by a single blower volute through the air inlet switching component, eliminating the need for two volutes, further reducing the space occupied by the bathroom heater, making better use of space and lowering the cost.

[0042] like Figure 1-19 The bathroom heater shown includes a housing 1, an air outlet assembly 2, a blower housing 3, a guide vane 4, and an air inlet switching assembly 5.

[0043] The housing 1 is equipped with an air outlet assembly 2, which has a first air inlet 201 and a first air outlet 202. The first air inlet 201 is located on the side wall of the air outlet assembly 2, and the first air outlet 202 is located on the top of the air outlet assembly 2. A guide 4 is connected to the first air inlet 201 of the air outlet assembly 2, and the guide 4 is fixed to the top of the first air inlet 201 of the air outlet assembly 2. The guide 4 is located at the top of the first air inlet 201, which effectively utilizes the space after the height of the air outlet assembly 2 is reduced, and at the same time can better guide the airflow from the first air inlet 201 into the interior of the air outlet assembly 2, ensuring the airflow intensity and efficiency. In this embodiment, the guide 4 is a wedge-shaped guide plate, and the angle α between the wedge-shaped guide plate and the horizontal plane is 30-60 degrees. To further improve the airflow guiding effect, the windward surface of the wedge-shaped guide plate is set as a concave arc surface. A heater 6 is fixedly connected to the first air outlet 202 of the air outlet assembly 2. The heater 6 heats the airflow, thereby providing warm air to the bathroom.

[0044] The housing 1 contains a blower volute 3, which has a second air inlet 301 and a second air outlet 302. The second air outlet 302 of the blower volute 3 is connected to the first air inlet 201 of the air outlet assembly 2 through a first air guide channel 7, so that the vertical height of the first air inlet 201 of the air outlet assembly 2 is lower than the vertical height of the second air outlet 302 of the blower volute 3. By reducing the height of the first air inlet 201, the height of the air outlet assembly 2 is correspondingly reduced, thereby reducing the overall thickness of the bathroom heater and the space occupied by the bathroom heater, providing more space for ceiling installation. In this embodiment, the first air guide channel 7 is formed by sequentially connecting and enclosing a first perimeter 701, a second perimeter 702, a side wall of the housing 1, a third perimeter 703, and a fourth perimeter 704. The first perimeter 701 surrounds the blower volute 3. The height of the first rim 701 is approximately the same as the height of the blower housing 3; the height of the second rim 702 is lower than the height of the first rim 701, and the heights of the third rim 703 and the fourth rim 704 are also lower than the height of the first rim 701; the air outlet assembly 2 is fixed to the second rim 702, the third rim 703, and the fourth rim 704. By lowering the height of the second rim 702, the third rim 703, and the fourth rim 704 of the air outlet assembly 2 fixing parts, the overall height of the air outlet assembly 2 is reduced, thereby reducing the overall height of the bathroom heater.

[0045] The casing 1 is also provided with an exhaust port 101. The second air outlet 302 of the blower volute 3 is connected to the exhaust port 101 through the first air guide channel 7 and the second air guide channel 8. The first air guide channel 7 and the second air guide channel 8 are connected through the third air inlet 102, which is located on the first enclosure 701. The second air guide channel 8 is formed by the fourth enclosure 704, the side wall of the casing 1, and the fifth enclosure 801 connected in sequence. An air inlet switching component 5 is fixed next to the first air inlet 201 of the air outlet assembly 2. The air inlet switching component 5 includes a motor 501 and a baffle 502. The baffle 502 is fixed on the output shaft of the motor 501, so that the motor 501 drives the baffle 502 to close the first air inlet 201 or the third air inlet 102, thereby realizing the switching between heating air outlet and ventilation air outlet to meet the needs of different application scenarios.

[0046] This utility model of a bathroom heater reduces the overall thickness and space occupied by lowering the height of the air outlet component 2 relative to the blower housing 3. However, reducing the height of the air outlet component 2 would lead to a decrease in air outlet efficiency. To ensure the air outlet efficiency of the bathroom heater, a guide component 4 is added to enhance the air outlet efficiency of the air outlet component 2, thus compensating for the efficiency loss caused by reducing the height of the air outlet component 2. While ensuring air outlet efficiency, the overall height of the bathroom heater is reduced, the space occupied is reduced, and the space utilization rate is higher.

[0047] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
