Description

Technical Field

[0001] This invention specifically relates to a bathroom heater with a detachable air duct structure. Background Technology

[0002] Currently, linear bathroom heaters on the market typically have long, narrow air outlets in the ceiling. To maximize airflow efficiency, these heaters use high-powered casings, resulting in a generally larger overall size. For example... Figure 1 As shown, when installing a linear bathroom heater, the unit needs to be tilted to the side so that it passes through the air outlet along its thickness into the installation space between the ceiling and the room. This requires sufficient distance between the ceiling and the room; otherwise, the heater's width will prevent it from fitting. However, most modern buildings have low ceilings, limiting the available space between the ceiling and the room, making it inconvenient or even impossible to install many linear bathroom heaters. How to ensure efficient airflow while facilitating installation remains a challenge.

[0003] Therefore, it is necessary to provide a bathroom heater with a detachable air duct structure, which divides the casing into two parts, namely a first casing and a second casing. The first casing and the second casing are detachably connected. During installation, the first casing and the second casing are first separated and passed through the air outlet into the space between the ceiling and the room ceiling, and then connected, which facilitates installation. Summary of the Invention

[0004] The purpose of this invention is to provide a bathroom heater with a detachable air duct structure, which solves the problem that linear bathroom heaters in the prior art are inconvenient to install in narrow spaces between the ceiling and the room.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A bathroom heater with a detachable air duct structure includes a housing, which includes a first housing and a second housing; a blower volute is fixed inside the first housing, and the first housing has an air inlet and an air outlet, with the air inlet facing the blower volute; the first housing and the second housing are detachably connected, so that the housing has a complete airflow channel.

[0007] In this invention, the first housing and the second housing are magnetically connected.

[0008] The present invention can be improved in the following way: the second housing is provided with a first airflow channel, and the first housing is provided with a first air outlet channel, so that the first air outlet channel and the first airflow channel are connected to form a complete airflow channel.

[0009] Furthermore, the first housing has an air exchange port, and the first housing is provided with a second air outlet channel, so that the second air outlet channel and the first airflow channel are connected to form a complete air exchange channel.

[0010] In some embodiments of the present invention, an airflow switching component is further included. This component comprises a motor, a fixed shaft, and a guide vane. The output shaft of the motor is driven by the fixed shaft, and the guide vane is fixed to the fixed shaft. This allows the motor to rotate the guide vane, switching the airflow direction so that the airflow from the blower housing flows through either the exhaust airflow channel to the vent or the ventilation airflow channel to the ventilation port. By using this switching component, a single blower housing can perform both exhaust and ventilation functions, reducing the space required for the bathroom heater (by eliminating the need for a separate blower housing) and making it easier to install the bathroom heater between the ceiling and the room's ceiling space.

[0011] Furthermore, the airflow switching component is located at the intersection of the first air outlet channel and the second air outlet channel.

[0012] In some embodiments of the present invention, the second housing is provided with a second airflow channel and a third airflow channel, which are stacked together; the first housing is provided with a third air outlet channel and a fourth air outlet channel, such that the second airflow channel and the third air outlet channel are connected to form a complete air outlet channel, and the third airflow channel and the fourth air outlet channel are connected to form a complete ventilation airflow channel. The stacked airflow channels in the second housing are connected to the air outlet channel in the first housing to form a ventilation airflow channel and an air outlet channel, thus rationally arranging the airflow channels, further reducing the overall volume of the bathroom heater, and facilitating its installation.

[0013] Furthermore, the blower housing is a bidirectional blower housing 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 air outlet is connected to the ventilation outlet through an air exchange channel, and the other air outlet is connected to the exhaust outlet through an exhaust air outlet channel. This design eliminates the need for a duct switching component; exhaust and ventilation functions can be achieved with a single bidirectional blower housing, further optimizing the airflow and reducing the size of the bathroom heater / ventilation unit.

[0014] Furthermore, the third and fourth air outlet channels are stacked; each of the third and fourth air outlet channels is directly opposite a layer of blades on the blower casing; the air outlet channel is an Archimedean spiral duct, and the ventilation airflow channel is also an Archimedean spiral duct. This further optimizes the duct structure, improving air delivery efficiency while reducing the size of the bathroom heater / ventilation unit.

[0015] In this invention, the second housing is an arc-shaped structure with an opening; the second housing includes a main body and a protrusion, the protrusion being connected to the main body; the main body is provided with a first groove, and the protrusion is provided with a second groove, such that the first groove forms a second airflow channel, and the second groove forms a third airflow channel.

[0016] Furthermore, the protrusion is stepped relative to the main body. This design reduces the space occupied by the first housing, facilitating the installation of the bathroom heater through the ceiling air vent.

[0017] Furthermore, the second housing also includes a fixing part, which is connected to the main body and the protrusion; the second housing is detachably connected to the first housing through the fixing part.

[0018] In this invention, the first housing is provided with a flow guide, which surrounds the third air outlet channel and is located below the fourth air outlet channel, causing the cross-section of the final section of the ventilation airflow channel to gradually increase. This arrangement allows the air inlet of the bathroom heater to act as a flow guide during air intake (exhaust or ventilation), improving the air intake efficiency. Simultaneously, during ventilation, the cross-section of the ventilation airflow channel gradually increases to match the ventilation opening, further improving ventilation efficiency.

[0019] The invention can be further improved by providing a heater at the exhaust vent.

[0020] Furthermore, an air guide is fixed to the heater, and the cross-section of the air guide is funnel-shaped. This arrangement allows the airflow to converge after passing through the air guide before being blown out from the exhaust port, resulting in a greater airflow velocity and improved airflow efficiency. In addition, the air guide can pass through the exhaust port and also provides support for the panel.

[0021] In this invention, the air inlet is located at the top of the first housing, the air exchange port is located on the side wall of the first housing, and the exhaust port is located at the top of the first housing, so that the airflow is blown out from the top of the housing.

[0022] The present invention has the following beneficial effects:

[0023] (1) The present invention has a detachable air duct structure. The bathroom heater has a first shell and a second shell, which are detachably connected. During installation, the two are separated and enter the space between the ceiling and the roof respectively, and then connected. After connection, a complete air duct is formed without affecting the function of the bathroom heater. This enables the bathroom heater to be installed quickly in a narrow installation space, which greatly improves the installation efficiency.

[0024] (2) When the first and second housings of the present invention are connected, a complete airflow duct is formed. By optimizing the airflow path and duct structure, the space occupied by the bathroom heater is reduced, further facilitating the installation of the bathroom heater. At the same time, while reducing space, the air delivery efficiency of the bathroom heater is ensured as much as possible. Attached Figure Description

An airflow switching component 7 is provided at the intersection of the first air outlet channel 5 and the second air outlet channel 6. The airflow switching component 7 includes a motor 701, a fixed shaft 702, and a guide plate 703; the output shaft of the motor 701 is drivenly connected to the fixed shaft 702, and the guide plate 703 is fixed on the fixed shaft 702, so that the motor 701 drives the guide plate 703 to rotate and switch the airflow direction, so that the airflow blown out by the blower volute 2 flows to the exhaust port 103 through the air outlet channel or to the ventilation port 101 through the ventilation channel.

[0050] Example 2

[0051] like Figure 8-19 The bathroom heater shown has a detachable air duct structure, including a housing 1, a blower housing 2, and a heater 3.

[0052] The housing 1 includes a first housing 104 and a second housing 105. The top of the first housing 104 has an air inlet 102 and a rectangular exhaust port 103. The side wall of the first housing 104 has a ventilation port 101.

[0053] The second housing 105 is an open, arc-shaped structure. The second housing 105 includes a main body 1051 and a protrusion 1052, with the protrusion 1052 connected to the main body 1051. The main body 1051 has a first groove 1054, and the protrusion 1052 has a second groove 1055, such that the first groove 1054 forms a second airflow channel 8, and the second groove 1055 forms a third airflow channel 9. The second airflow channel 8 and the third airflow channel 9 are stacked. In this embodiment, the protrusion 1052 and the main body 1051 are arranged in a stepped manner. The second housing 105 also includes a fixing part 1053, which is connected to the main body 1051 and the protrusion 1052.
