Description

Technical Field

[0001] This utility model relates to the field of bathroom heater technology, specifically to a heater with an arc-shaped air inlet and outlet. Background Technology

[0002] Currently, there are two main types of bathroom heaters on the market: fan heaters and bathroom heaters (or similar units). Fan heaters work by drawing in air through a rotating fan, heating it, and then blowing it out, or heating the air during the blowing process, thus raising the room temperature. Existing fan heaters typically include a casing, an air chamber inside the casing, a rotating fan installed in the air chamber, an air inlet on the casing connected to the fan, an air outlet on the casing connected to the fan, and a heater between the air outlet and the fan. However, the design of the air inlet and outlet on the casing in existing technologies is not aesthetically pleasing. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a heater with an arc-shaped air inlet and outlet.

[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0008] The panel and the chassis are connected by a quick-release mechanism.

[0009] In a preferred embodiment, the inner and outer sides of the first air inlet are respectively provided with a connecting plate and a guide plate extending inward. The two ends of the connecting plate are closedly connected to the two ends of the guide plate. The inner end of the guide plate is curved toward the connecting plate and closedly connected to the inner end of the connecting plate. An air inlet hole communicating with the second air inlet is provided on the connecting plate.

[0010] In a preferred embodiment, the inner end of the air outlet is connected to an air collecting hood, and the air outlet and the air collecting hood are in communication. The inner end of the air collecting hood abuts against the upper end of the chassis and covers the air outlet.

[0011] In a preferred embodiment, the upper edge of the chassis has four connecting walls extending upwards. The panel covers the upper end of the connecting walls. The quick-release structure includes a matching spring and a insert. One end of the spring is fixedly installed on the upper end of the chassis, and the other end of the spring extends towards the panel. The spring has an arched portion that curves towards the corresponding connecting wall. The arched portion abuts against the corresponding connecting wall by the elastic force of the spring. The upper end of the insert is fixedly connected to the panel. The insert is attached to the inner side of the connecting wall and inserted between the spring and the connecting wall. The side of the insert away from the connecting wall has a protrusion located at the lower end of the arched portion.

[0012] In a preferred embodiment, a ventilation port is provided on one side of the chassis, and the ventilation port is connected to the ventilation channel inside the chassis. A ventilation outlet is connected to one side of the air cavity, and the ventilation outlet is connected to the blowing channel and the ventilation channel. A switching damper is provided at the intersection of the ventilation outlet, the blowing channel and the ventilation channel, and the switching damper is used to connect the ventilation outlet and the blowing channel or the ventilation outlet and the ventilation channel.

[0013] In a preferred embodiment, the switching damper includes a baffle plate, one side of which is rotatably mounted at the connection between the inner wall of the blowing channel and the air exchange channel. The baffle plate is driven to rotate by a motor, and the rotation of the baffle plate can close the blowing channel or the air exchange channel.

[0014] In a preferred embodiment, the two ends of the air inlet and the two ends of the air outlet are arranged in a circle, close to each other.

[0015] Compared with existing technologies, the beneficial effects are:

[0016] This utility model has a simple structure and is easy to use. By setting the air inlet and the air outlet to an arc shape, the length of the air inlet and the air outlet on the panel can be increased, thereby increasing the air intake and air blowing volume. In addition, the panel and the chassis are connected by a quick disassembly structure, which improves the efficiency and convenience of installation and maintenance. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] A heater with an arc-shaped air inlet and outlet includes a housing 1 and a panel 2 covering the top of the housing 1.

[0027] The casing 1 is provided with a wind chamber 9, and a wind turbine assembly 10 is installed in the wind chamber 9. The wind turbine assembly 10 includes a wind turbine that is rotatably installed in the wind chamber 9 and a motor that drives the wind turbine to rotate. The upper end of the casing 1 is provided with an air inlet 8 and an air outlet 17. The air inlet 8 is connected to the upper end of the wind chamber 9. One side of the wind chamber 9 is connected to the air outlet 17 through a blowing channel 12. A heater 16 is provided at the air outlet 17. The heater 16 is a PTC heater.

[0028] The panel 2 has an air inlet 3 and an air outlet 4 that are respectively connected to the air inlet 8 and the air outlet 17. The air inlet 3 and the air outlet 4 are both curved into an arc shape.

[0029] The panel 2 is connected to the chassis 1 via a quick-release assembly / disassembly structure.

[0030] By setting the air inlet 3 and the air outlet 4 to an arc shape, the length of the air inlet 3 and the air outlet 4 on the panel 2 can be increased, thereby increasing the air intake and air blowing volume; in addition, the panel 2 and the chassis 1 are connected by a quick-release structure, which improves the efficiency and convenience of installation and maintenance.

[0031] In a preferred embodiment, the inner and outer sides of the air inlet 3 are respectively provided with a connecting plate 6 and a guide plate 5 extending inward. The two ends of the connecting plate 6 are closedly connected to the two ends of the guide plate 5. The inner end of the guide plate 5 is curved towards the connecting plate 6 and closedly connected to the inner end of the connecting plate 6. The connecting plate 6 has an air inlet hole 7 communicating with the second air inlet 8. The airflow entering from the air inlet 3 is guided by the guide plate 5 and then turns towards the connecting plate 6. It enters the gap between the panel 2 and the chassis 1 through the air inlet hole 7 on the connecting plate 6, and then enters the air cavity 9 through the second air inlet 8 on the chassis 1. The curved design of the guide plate 5 allows for smooth guidance.

[0032] In a preferred embodiment, the inner edge of the air outlet 4 is connected to an air collecting hood 18, and the air outlet 4 communicates with the air collecting hood 18. The inner end of the air collecting hood 18 abuts against the upper end of the chassis 1 and covers the air outlet 17. The air collecting hood 18 serves as a channel connecting the air outlet 17 and the air outlet 17.

[0033] In a preferred embodiment, the upper edge of the chassis 1 has four connecting walls 21 extending upwards. The panel 2 covers the upper end of the connecting walls 21. The quick-release structure includes a matching spring 19 and a insert 20. One end of the spring 19 is fixedly installed on the upper end of the chassis 1, and the other end of the spring 19 extends toward the panel 2. The spring 19 is curved with an arched portion 22 facing the corresponding connecting wall 21. The arched portion 22 is pressed against the corresponding connecting wall 21 by the elastic force of the spring 19. The upper end of the insert 20 is fixedly connected to the panel 2. The insert 20 is attached to the inner side of the connecting wall 21 and inserted between the spring 19 and the connecting wall 21. The side of the insert 20 away from the connecting wall 21 has a protruding portion 23 located at the lower end of the arched portion 22. The elasticity of the spring 19 causes the arched portion 22 to press the insert 20 against the inner side of the connecting wall 21. Furthermore, the protrusion 23 on the insert 20 engages with the arched portion 22, ensuring that the insert 20 will not detach from the spring 19 and the connecting wall 21 without external force, thus fixing the panel 2 to the chassis 1. During installation, simply insert the insert 20 directly between the spring 19 and the connecting wall 21; during disassembly, simply apply external force to pull the insert 20 out from between the spring 19 and the connecting wall 21. This quick and convenient process improves efficiency and ease of use.

[0034] In a preferred embodiment, a ventilation port 14 is provided on one side of the chassis 1, and the ventilation port 14 is connected to the ventilation channel 13 inside the chassis 1. A ventilation outlet 11 is connected to one side of the air cavity 9, and the ventilation outlet 11 is connected to the blowing channel 12 and the ventilation channel 13. A switching damper is provided at the intersection of the ventilation outlet 11, the blowing channel 12 and the ventilation channel 13. The ventilation outlet 11 is connected to the blowing channel 12 or the ventilation outlet 11 is connected to the ventilation channel 13 by switching the damper.

[0035] In a preferred embodiment, the switching damper includes a baffle plate 15. One side of the baffle plate 15 is rotatably installed at the connection between the inner wall of the blowing channel 12 and the air exchange channel 13. The baffle plate 15 is driven to rotate by a motor. The baffle plate 15 can close the blowing channel 12 or the air exchange channel 13 by rotating.

[0036] In a preferred embodiment, the two ends of the air inlet 3 and the two ends of the air outlet 4 are arranged close to each other to form a circle, specifically, in a circular shape.
