Description

Technical Field

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

[0002] Currently, most bathroom heaters on the market, which combine heating and ventilation functions, have one ventilation vent and one exhaust vent. They mostly employ a double-volute structure, with one volute for heating and the other for ventilation. To achieve a larger airflow, a higher-power volute is usually required, or the airflow efficiency needs to be improved while maintaining the same volute power, resulting in a generally larger unit size. Linear bathroom heaters, on the other hand, have a compact structure. Compared to standard bathroom heaters, they are elongated and narrower, occupying less space and allowing for more diverse applications. Improving the airflow efficiency of linear bathroom heaters within limited space remains a major challenge for the industry.

[0003] Therefore, it is necessary to provide a linear bathroom heater that uses dual volutes to deliver air simultaneously, which greatly improves the ventilation or heating effect of the linear bathroom heater, increases the utilization efficiency of the volutes, and has a higher cost performance. Utility Model Content

[0004] The purpose of this invention is to provide a linear bathroom heater that solves the problem of low single-unit blowing efficiency in existing linear bathroom heaters.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A linear bathroom heater, characterized in that it includes a housing, the housing having an air vent, the housing having an air exchange channel, the air vent being located at one end of the air exchange channel, two blower volutes being located at the other end of the air exchange channel, and the air outlets of the blower volutes being connected to the air vent through the air exchange channel.

[0007] In this invention, the ventilation channel is provided with an airflow partition plate, so that the airflow from the two blower volutes blowing towards the ventilation port through the ventilation channel does not affect each other.

[0008] Furthermore, the airflow partition plate is located at the air exchange port to guide the airflow blown towards the air exchange port by the blower casing.

[0009] In this invention, the housing is provided with an air inlet, which is positioned directly opposite the air inlet of the blower volute.

[0010] In some embodiments of this invention, the ventilation channel has a symmetrical structure and is heart-shaped, gradually narrowing from one end to the other; two blower volutes are symmetrically arranged in the wide portion of the ventilation channel; and the ventilation port is located in the narrow portion of the ventilation channel. This arrangement results in lower airflow resistance and better ventilation performance.

[0011] Furthermore, the air exchange port is located on the side wall of the housing, and the air inlet is located on the top of the housing; the airflow partition plate is arranged perpendicular to the air exchange port.

[0012] The present invention can be improved in the following ways: the housing has an exhaust port, the housing has an air outlet channel, each air outlet of the blower volute is connected to an exhaust port through the air outlet channel, and a heater is provided at the exhaust port.

[0013] In some embodiments of this utility model, the air outlet channel is formed by a first surrounding edge, a second surrounding edge, a third surrounding edge, and a fourth surrounding edge connected in sequence; the first surrounding edge is radially spiral-shaped and surrounds the outer periphery of the blower casing; the second surrounding edge is arc-shaped; the third and fourth surrounding edges are straight; and the air outlet channel gradually narrows along the airflow direction. With this design, the air outlet channel has lower airflow resistance, better guides airflow to the exhaust port, and reduces losses.

[0014] Furthermore, there are two air outlet channels, symmetrically arranged inside the casing; and two exhaust vents, located on the top of the casing.

[0015] This invention can be further improved by having a rotating wheel with two layers of blades. One layer of blades is arranged counterclockwise, and the other layer is arranged clockwise, giving the blower housing two air outlets. One outlet connects to the ventilation channel, and the other connects to the exhaust channel. This arrangement allows the clockwise and counterclockwise rotation of the blower housing wheel to create different airflow outlets, which are directed to the ventilation port through the ventilation channel and to the exhaust port through the exhaust channel, respectively. Thus, this blower housing can perform two functions: ventilation and heating, resulting in high utilization of the mechanism. Simultaneously, the two blower housings work together, enabling this bathroom heater to operate in multiple modes: first, both blower housings simultaneously blow towards the exhaust port for strong heating; second, both blower housings simultaneously blow towards the ventilation port for strong ventilation; third, one blower housing blows towards the ventilation port, and the other towards the exhaust port, simultaneously providing heating and ventilation.

[0016] Furthermore, the ventilation channel and the air outlet channel are stacked. This arrangement reduces the space occupied by the air duct and the size of the bathroom heater / ventilation unit.

[0017] In some embodiments of this invention, the two blower housings are arranged parallel to each other on the same horizontal plane, and the ventilation channel is stacked above the air outlet channel. This arrangement reduces the vertical space occupied by the channel, thus reducing the thickness of the bathroom heater / ventilation unit.

[0018] In some embodiments of this invention, the two blower volutes are staggered on different horizontal planes. This arrangement reduces the area occupied by the channel in the horizontal direction.

[0019] This utility model has the following beneficial effects:

[0020] (1) The present invention uses two blower volutes. Compared with the existing bathroom heaters, the air supply channel is improved so that the two blower volutes are connected to the air exchange port through the air exchange channel, and the air exchange is carried out simultaneously, which improves the utilization rate of the blower volutes and improves the blowing efficiency of the single unit of the linear bathroom heater. One bathroom heater is equivalent to the function of two original bathroom heaters, but the body volume only occupies the space of one bathroom heater.

[0021] (2) This utility model of linear bathroom heater also improves the effect of delivering warm air by sending air to the exhaust port through two blower volutes via the air outlet channel. To achieve the above functions, a bidirectional blower volute is selected, with different air outlets for different directions, thereby switching the airflow into the ventilation channel or the exhaust channel, improving the utilization rate of the volute, improving the blowing effect, and providing high cost performance.

[0036] like Figure 1-12 The linear bathroom heater shown includes a housing 1, a blower housing 2, and a heater 3.

[0037] The top of the casing 1 has two circular air inlets 102 and two rectangular air outlets 103, and the side wall has a ventilation port 101.

[0038] Two air outlet channels 5 are symmetrically arranged inside the housing 1. Two blower volutes 2 are each located within one air outlet channel 5. The air outlet 201 of each blower volute 2 is connected to an exhaust port 103 via the air outlet channel 5. A heater 3 is provided at the exhaust port 103. In this embodiment, the two blower volutes 2 are arranged parallel to each other on the same horizontal plane. The air outlet channel 5 is formed by sequentially connecting and enclosing a first perimeter 501, a second perimeter 502, a third perimeter 503, and a fourth perimeter 504. The first perimeter 501 is radially spiral-shaped and surrounds the outer perimeter of the blower volute 2. The second perimeter 502 is arc-shaped. The third perimeter 503 and the fourth perimeter 504 are straight lines. The air outlet channel 5 gradually narrows along the airflow direction. This arrangement results in lower airflow resistance in the air outlet channel 5, better guiding the airflow to the exhaust port 103 and reducing losses.

[0039] The housing 1 also includes a ventilation channel 4, which is stacked above the air outlet channel 5. The ventilation channel 4 has a symmetrical structure and is heart-shaped, gradually narrowing from one end to the other. Two blower volutes 2 are symmetrically arranged in the wider portion of the ventilation channel 4. The air inlets 202 of the blower volutes 2 are directly opposite the air inlets 102 on the housing 1. The air outlet 101 is located in the narrower portion of the ventilation channel 4, and the air outlets 201 of the blower volutes 2 are connected to the air outlet 101 through the ventilation channel 4. An airflow partition 6 is provided at the air outlet 101, which is perpendicular to the air outlet 101. The partition 6 guides the airflow from the blower volutes 2 towards the air outlet 101 and blocks the airflow from the two blower volutes 2 towards the air outlet 101, preventing the two airflows from interfering with each other and causing losses. This invention achieves better ventilation by using two blower volutes 2 to perform ventilation simultaneously compared to using a single blower volute 2. At the same time, the two blower volutes 2 can provide heating air simultaneously, which also achieves better heating effect compared to using a single blower volute 2.

[0040] To enable a single blower housing 2 to function as both a ventilation and heating unit, this invention features a rotor 203 with two layers of blades. One layer of blades rotates counter-clockwise, while the other rotates clockwise, giving the blower housing 2 two air outlets 201. One outlet 201 connects to the ventilation channel 4, and the other connects to the exhaust channel 5. This arrangement allows the rotor 203 to generate different airflows at the outlets 201 as it rotates clockwise and counter-clockwise. These airflows are directed through the ventilation channel 4 to the ventilation port 101 and through the exhaust channel 5 to the exhaust port 103, respectively. Thus, the blower housing 2 can perform both functions: ventilation and heating, resulting in high structural efficiency. Simultaneously, the two blower housings 2 work together, enabling this new type of bathroom heater to operate in multiple modes. First, both blower housings 2 simultaneously blow air towards the exhaust vent 103, providing strong warm air supply. Second, both blower housings 2 simultaneously blow air towards the ventilation vent 101, achieving strong ventilation. Third, one blower housing 2 blows air towards the ventilation vent 101, while the other blows air towards the exhaust vent 103, simultaneously providing warm air supply and ventilation. With the same power output for each blower housing 2, this significantly improves structural utilization, achieving stronger ventilation and heating effects. One bathroom heater can achieve the functionality of two existing bathroom heaters, while occupying only the space of one existing unit.
