Description

Technical Field

[0001] This invention 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. Summary of the Invention

[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 the present invention 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 in the middle of the air exchange channel, and a blower volute being provided at each end of the air exchange channel, the air outlet of the blower volute 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 airflows blown by the air volutes at both ends of the ventilation channel toward the ventilation port do 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 the present invention, the ventilation channel has a symmetrical structure, with the width gradually narrowing towards the middle at both ends; two blower volutes are symmetrically arranged at the wide portions of both ends of the ventilation channel; the ventilation port is located at the bottom of the housing, and the air inlet is located at the top of the housing; the airflow partition is arranged perpendicular to the ventilation port and directly opposite the air outlet of the blower volute.

[0011] The present invention can be improved in the following ways: the housing has an exhaust port, the housing has an air outlet channel, the two ends of the air outlet channel are respectively connected to the air outlet of the blower volute, the exhaust port is located in the middle of the air outlet channel, and a heater is provided at the exhaust port.

[0012] Furthermore, the air outlet channel is provided with an airflow guide plate, which is composed of two arc-shaped plates connected together, so that the airflow blown by the air volutes at both ends of the air outlet channel to the exhaust port flows through the heater and then flows out of the exhaust port without affecting each other.

[0013] Furthermore, the exhaust vent is located on the side wall of the casing.

[0014] The invention can also be improved in the following ways: the ventilation channel is formed by connecting a common channel section and a ventilation channel section; the air outlet channel is formed by connecting a common channel section and an air outlet channel section; the common channel section is the common part of the ventilation channel and the air outlet channel. This arrangement saves space occupied by the channels and reduces the overall size of the bathroom heater / ventilation unit.

[0015] Furthermore, it also includes a switching component, which includes a motor and a baffle. The baffle is fixedly connected to the output shaft of the motor, so that the airflow blown out by the blower volute is guided to the ventilation port or exhaust port through the switching component.

[0016] Furthermore, the switching components are in two sets, and are fixed to both ends of the airflow guide plate. With this configuration, the bathroom heater can operate in multiple modes: first, both blower housings simultaneously blow towards the exhaust vent for strong warm air supply; second, both blower housings simultaneously blow towards the ventilation vent for strong ventilation; third, one blower housing blows towards the ventilation vent and the other blows towards the exhaust vent, simultaneously supplying warm air and providing ventilation.

[0017] In some embodiments of the present invention, the air outlet channel has a symmetrical structure, and the airflow guide plate is symmetrically arranged in the air outlet channel.

[0018] The present invention has the following beneficial effects:

[0019] (1) Based on the existing bathroom heater, the linear bathroom heater of the present invention adopts two blower volutes and improves the air supply channel, so that the two blower volutes can simultaneously supply air to the ventilation port or the exhaust port, thereby greatly improving the utilization rate of the blower volutes of a single unit and improving the air supply effect. The linear bathroom heater has a higher cost performance per unit.

[0020] (2) The linear bathroom heater of this invention also switches the airflow of the blower housing by switching components, allowing the airflow to flow to the ventilation channel or the air outlet channel, thus realizing multiple operating modes and meeting more usage needs. When the two blower housings deliver air to the exhaust vent through the air outlet channel, the effect of the bathroom heater in delivering warm air is improved. One bathroom heater is equivalent to the function of two original bathroom heaters, but the body size only occupies the space of one bathroom heater. Attached Figure Description

[0033] like Figure 1-10The linear bathroom heater shown includes a housing 1, a blower housing 2, a switching component 3, and a heater 4.

[0034] The casing 1 has two circular air inlets 102 at the top, a rectangular air vent 101 at the bottom, and an exhaust vent 103 on the side wall. An air exchange channel 5 is provided inside the casing 1. The air exchange channel 5 has a symmetrical structure, gradually narrowing from both ends towards the middle. Two blower volutes 2 are symmetrically arranged at the wider portions of both ends of the air exchange channel 5. The air inlets 202 of the blower volutes 2 are directly opposite the air inlets 102 on the casing 1. The air vent 101 is located in the narrower portion of the air exchange channel 5, and the air outlets 201 of the blower volutes 2 are connected to the air vent 101 through the air exchange channel 5. An airflow divider 7 is provided at the air vent 101 to guide the airflow from the blower volutes 2 towards the air vent 101, while simultaneously blocking the airflow from the two blower volutes 2 to prevent the two airflows from interfering with each other and causing losses. This invention achieves better ventilation results by using two blower volutes 2 for simultaneous ventilation compared to ventilation with a single blower volute 2.

[0035] The housing 1 also includes an air outlet duct 6, which has a symmetrical structure. Both ends of the air outlet duct 6 are connected to the air outlet 201 of a blower volute 2. An exhaust port 103 on the side wall of the housing 1 is positioned directly opposite the center of the air outlet duct 6, and a heater 4 is located at the exhaust port 103. An airflow guide plate 8 is composed of two connected arc-shaped plates, symmetrically positioned within the air outlet duct 6. This allows the airflow from the blower volutes 2 at both ends of the air outlet duct 6 to pass through the airflow guide plate 8 and be directed towards the heater 4. After passing through the heater 4, the airflow exits from the exhaust port 103. The airflow guide plate 8 guides the airflow and prevents the airflow from the two blower volutes 2 from interfering with each other.

[0036] To meet the requirement of a small size for linear bathroom heaters, this invention improves the ventilation channel 5 and the air outlet channel 6, making them share a common channel section 9, thereby saving space occupied by the internal channels of the bathroom heater. Specifically, the ventilation channel 5 is formed by connecting the common channel section 9 and the ventilation channel section 10; the air outlet channel 6 is formed by connecting the common channel section 9 and the air outlet channel section 11; the common channel section 9 is the common part of the ventilation channel 5 and the air outlet channel 6. The airflow blown out by the blower housing 2 is switched through the switching component 3, so that the airflow flows to the ventilation port 101 or the exhaust port 103. The two switching components 3 are respectively fixed to the two ends of the airflow guide plate 8. The switching component 3 includes a motor 301 and a baffle 302. The baffle 302 is fixedly connected to the output shaft of the motor 301. By controlling the swing of the baffle 302, the airflow channel is switched. With this configuration, the present invention's bathroom heater, through its two volutes, can achieve multiple operating modes. First, both blower volutes 2 simultaneously blow air towards the exhaust vent 103, providing strong warm air supply. Second, both blower volutes 2 simultaneously blow air towards the ventilation vent 101, achieving strong ventilation. Third, one blower volute 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 each blower volute 2 having the same power, this significantly improves structural utilization, achieving stronger ventilation and heating effects. One bathroom heater can achieve the effect of two existing bathroom heaters, while occupying only the space of one existing bathroom heater.
