Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a heater structure. Background Technology
[0002] Currently, bathroom heaters on the market generally adopt two types of air supply methods: a single-motor bidirectional air supply system and a dual-motor dual-airflow system. The single-motor bidirectional air supply system is easier to control costs, but it suffers from some loss in overall airflow and air pressure, resulting in poor overall performance. The dual-motor dual-airflow system is more expensive, but its performance is significantly improved compared to the single-motor system. Although some new air supply methods, such as diagonal flow fan systems and backward-tilted centrifugal air supply systems, have emerged in the market, these products are currently relatively niche due to cost and other issues.

Furthermore, it should be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the actual scope of protection. All raw materials used in the following embodiments are commercially available products.
[0019] Example 1
[0020] like Figures 1-4 As shown, a heater structure includes a housing 1 and a cover plate 2. The cover plate 2 seals the housing 1. A housing partition 5 is also provided inside the housing 1, dividing the housing 1 into upper and lower parts. The upper part of the housing partition 5 is a ventilation area, and the lower part of the housing partition 5 to the bottom of the housing 1 is a heating area. A first volute 3 is provided in the heating area, and warm air ducts 4 are respectively connected to the left and right ends of the first volute 3. The housing partition 5 has partition warm air inlets 9 corresponding to the two warm air ducts 4, and a heating device 20 is installed inside the partition warm air inlets 9. A fan wheel mounting port 6 is provided in the center of the partition warm air inlet 9, and the fan wheel mounting port 6 is located outside... A second volute 7 is provided on the top surface of the side partition 5. A ventilation duct 8 is connected to the front or rear of the second volute 7. A ventilation port 17 is opened in the box 1 corresponding to the ventilation duct 8. A fan 15 is provided in the first volute 3. The output end of the fan 15 is connected to a fan wheel 16. The lower part of the fan wheel 16 is located in the first volute 3, and the upper part of the fan wheel 16 is located in the second volute 7 through the fan wheel mounting port 6. The fan wheel blades located in the first volute 3 and the fan wheel blades located in the second volute 7 are arranged in opposite directions. An air inlet 11 is opened in the cover plate 2 corresponding to the fan wheel 16, and a warm air outlet 10 is opened in the partition warm air inlet 9.
[0021] The bottom of the first volute 3 has a wire hole, and a wire groove is provided from the wire hole to the center of the bottom of the first volute 3. The fan wire is placed in the wire groove and its end passes through the wire hole.
[0022] The enclosure partition 5 is also provided with an electrical control box installation port 12. The cover plate 2 is provided with an electrical control box 13 corresponding to the electrical control box installation port 12. When the cover plate 2 covers the enclosure 1, the electrical control box 13 is embedded in the electrical control box installation port 12. The top of the electrical control box 13 is covered by the electrical control cover plate 14.
[0023] A heating zone fixing post is provided on the outside of the first volute 3 or the heating air duct 4. A ventilation zone fixing post is provided on the box partition 5 corresponding to the heating zone fixing post. A fixing hole is opened on the cover plate 2 corresponding to the ventilation zone fixing post.
