Description

Technical Field

[0001] The present invention relates to the technical field of heaters, and more particularly to a bathroom heater. Background Art

[0002] Currently, bathroom heaters are primarily used in bathrooms to provide warmth while showering. Surveys have shown that bathroom heaters are frequently used in areas such as Guangdong, Jiangsu, Zhejiang, Shanghai, the southwestern Sichuan and Chongqing regions, Anhui, Jiangxi, and Fujian. These regions also experience cold and rainy winters and hot and humid summers, often with continuous rain or the rainy season. Bathrooms are often damp after showering, which can easily breed bacteria. This can cause cabinets and items to become damp and moldy, damaging the interior and affecting air quality. Furthermore, the damp floor after showering can make it easy for users to fall when entering and exiting the bathroom, creating safety risks. Wet towels hanging in the bathroom can easily breed mold and spread diseases. This is caused by the high temperature and humidity in the bathroom. Prolonged exposure to high humidity can accelerate the aging of electrical appliances and even lead to safety issues such as electrical leakage. Many bathrooms lack windows, which further contributes to the air's stuffiness. Stuffy bathroom air, with its high water content, can affect the bathroom environment and oxygen levels. Therefore, some bathroom heaters have an exhaust function. However, when the exhaust function is in operation, air will leak out from the air outlet, resulting in low exhaust efficiency. At the same time, when the weather is cold, cold air will be blown out, affecting the user experience. The reason is that when the exhaust function is running, the air flow in the air duct at the air outlet will be diverted by the air duct, and part of the air will overflow from the air outlet; when the blowing function is in operation, air will leak out from the exhaust port, resulting in a small amount of blowing air. The reason is that when the exhaust function is running, the air flow in the air duct at the air outlet will be diverted by the air duct, and part of the air will overflow from the air outlet.

[0003] Therefore, it is necessary to provide a bathroom heater which has a simple structure but can effectively solve the above problems, which has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a bathroom heater with a simple structure, stable performance and incremental air outlet.

[0005] The present invention adopts the following technical solutions to achieve the above-mentioned purpose: a bathroom heater with incremental air outlets, characterized in that it includes a shell and an air duct and a wind wheel assembly arranged therein, the shell is provided with an air inlet corresponding to the wind wheel assembly, the shell is provided with a blowing air outlet, an exhaust outlet, and an incremental air outlet connected to the air duct, through the setting of the incremental air outlets, when the exhaust function is running, the diverted air is discharged from the incremental air outlets and then discharged outdoors through circulation; when the blowing function is running, the negative pressure air outside the shell is caused to flow into the air duct through the setting of the incremental air outlets, thereby increasing the blowing air volume.

[0006] As a further explanation of the above scheme, a first diversion guide corresponding to the exhaust port is provided in the air duct, and the first diversion guide is led out from the side wall of the air duct; a second diversion guide corresponding to the incremental air port is provided in the air duct, and the second diversion guide is led out from the side wall of the air duct.

[0007] Furthermore, the incremental air inlet is arranged between the wind wheel assembly and the air blowing outlet.

[0008] Furthermore, the air outlet is provided with an electric heating device, and a mesh cover is provided outside the electric heating device.

[0009] Furthermore, there is a vortex partition plate between the air blowing outlet and the incremental air outlet, which is used to prevent the formation of vortex between the air blowing outlet and the incremental air outlet, thereby reducing the blowing air volume.

[0010] Furthermore, the first diversion guide and the second diversion guide are respectively provided with strip-shaped or hole-shaped noise reduction structures.

[0011] The beneficial effects that can be achieved by the present invention by adopting the above technical solutions are:

[0012] The present invention adopts the ingenious design of adding incremental air outlets on the air duct and cooperating with the diversion guide and other parts, so that when the exhaust function is running, the diverted wind is discharged from the incremental air outlet and then discharged outdoors through circulation, and will not be discharged from the blowing outlet, avoiding the problem of cold wind in winter; and when the blowing function is running, the setting of the incremental air outlet makes the shell instantly form a negative pressure, so that the air outside the shell with negative pressure flows into the air duct, thereby increasing the blowing air volume and greatly improving the use effect.

[0022] The following description of the embodiments of the present invention is further described in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present invention clearer and more specific. The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present invention, but is not to be construed as limiting the present invention.

[0023] like Figure 1-Figure 4 As shown, the present invention is a bathroom heater with incremental air outlets. It includes a housing 1, an air duct 2 disposed therein, and a wind wheel assembly 3. The housing is provided with an air inlet 4 corresponding to the wind wheel assembly. The housing 1 is provided with a blower outlet 5, an exhaust outlet 6, and incremental air outlets 7 connected to the air duct. The air duct is C-shaped, and the wind wheel assembly 3 is composed of two centrifugal wind wheels. The exhaust outlet 6 and the incremental air outlet 7 are respectively connected to the ends of the air duct, and the incremental air outlet 7 is disposed between the wind wheel assembly 3 and the blower outlet 5. In this embodiment, an incremental air duct 15 is disposed between the air duct and the incremental air outlet. The incremental air duct is arranged at an angle and connected to the air duct 2, facilitating smooth air flow entering or exiting the air duct through the incremental air outlet. To prevent foreign matter or small animals from entering the bathroom heater through the incremental air outlet, a grille-shaped mesh cover 8 is provided over the incremental air outlet 7. The blower outlet is provided with an electric heating device 9, and a mesh cover 10 is disposed outside the electric heating device. A vortex barrier plate 11 is located between the air outlet 5 and the incremental air outlet 7 to prevent vortices from forming between them, which would prevent negative pressure from forming outside the incremental air outlet. In this embodiment, the vortex barrier plate 11 is positioned to one side of the air outlet, slanting from the sidewall of the air duct 2 toward the air outlet. There are two vortex barrier plates, positioned in tandem, with a gap between the front and rear vortex barrier plates.

[0024] The rotor assembly 3 includes a rotor 3-1, which is positioned within the air duct, and a rotor shaft 3-2. The rotor comprises an annular rotor body 3-11 formed with multiple blades, a boss 3-12 positioned in the middle of the annular rotor body, and a connecting plate 3-13, which is provided with multiple hollow holes 3-14, connecting the lower portion of the boss to the annular rotor body. One end of the rotor shaft is fixed to the housing, while the other end passes through the boss and is positioned by a corresponding nut, allowing the rotor to rotate within the housing. A gap is formed between the annular rotor body and the sidewall of the air duct, forming a gas channel 3-15.

[0025] Furthermore, a first diverter guide 12 corresponding to the exhaust port is provided in the air duct 2, and the first diverter guide is led out from the side wall of the air duct. A second diverter guide 13 corresponding to the incremental air port is provided in the air duct, and the second diverter guide is led out from the side wall of the air duct. The first diverter guide helps to guide the fluid during the blowing operation to prevent the fluid from overflowing from the exhaust port. The second diverter guide helps to increase the negative pressure value outside the incremental air port during the blowing operation, so that more outside air flows into the air duct. In this embodiment, the second diverter guide extends outward from the outlet position of the incremental air duct 15. The first diverter guide and the second diverter guide are respectively provided with a strip-shaped noise reduction structure. It is worth noting that a hole-shaped noise reduction structure can also be used. An air duct inner wall 14 that extends obliquely toward the wind wheel is provided on one side of the blowing outlet. The air duct is composed of two centrifugal air ducts in a U-shape, and the blowing and ventilation functions are realized through the forward and reverse rotation of the wind wheel. The first diversion guide is triangular in shape and extends toward the inner wall of the air duct. The second diversion guide is triangular in shape and extends toward the air outlet. Multiple ribs 14-1 are provided on the side of the inner wall of the air duct to assist in securing the mesh cover of the air outlet. It is worth noting that the shape of the diversion guide can be varied as needed, such as being configured as an arc-shaped plate.

[0026] Compared with the prior art, the present invention, through the setting of incremental air vents, allows the diverted air to be discharged from the incremental air vents when the exhaust function is in operation, and then circulated and discharged outdoors; when the blowing function is in operation, the setting of the incremental air vents allows the negative pressure air outside the shell to flow into the air duct, thereby increasing the blowing air volume.

[0027] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
