Description

Technical Field

[0001] This invention relates to the field of heater technology, and particularly to a bladeless cold and heat heater. Background Technology

[0002] A bladeless heater is a heating device that combines electric heating elements and bladeless fan technology. The working principle of a bladeless heater is mainly based on the heating characteristics of the electric heating element and the airflow technology of the bladeless fan. When an electric current passes through the heating element, the heat generated inside is proportional to its resistance, thus producing heat.

[0003] Meanwhile, bladeless fans utilize internal airflow multiplication technology to heat the drawn-in cold air through an electric heating element before expelling it, thus providing warmth. Furthermore, some bladeless heaters also feature a dual-function heating and cooling system; by adjusting the internal mechanism, they can deliver cool air in summer, achieving multiple uses in one unit.

[0004] The existing technical solution does not effectively combine the heating and cooling functions. It simply turns off the heating element when blowing cold air to achieve the purpose of blowing cold air. However, there is an obstruction when the air blows over the heating element, resulting in a poor airflow.

[0005] Therefore, there is an urgent need for a new bladeless heater that can switch between cold and warm air while maintaining a good airflow. Utility Model Content

[0045] The air duct control assembly includes a diversion air duct 8, a rotating plate 14, a motor 15, and a rotating plate bracket 16. The diversion air duct 8 is disposed on the top cover 4 of the base. The rotating plate bracket 16 is disposed below the diversion air duct 8. The rotating plate 14 and the motor 15 are respectively disposed on the rotating plate bracket 16. The motor 15 can drive the rotating plate 14 to rotate relative to the diversion air duct 8.

[0046] The diversion duct 8 is provided with a first air outlet 8.1 and a second air outlet 8.2. The side of the second air outlet 8.2 is also provided with a diversion hole 8.3. The second air outlet 8.2 is connected to the heating element support 13. The first air outlet 8.1 is connected to the first air column 1 and the third air column 3 respectively.

[0047] The rotating plate 14 includes a rotating shaft, a first baffle 14.1, and a second baffle 14.2. The first baffle 14.1 and the second baffle 14.2 are respectively fixedly connected to the side of the rotating shaft to form a fixed angle (e.g., 90°). The output shaft of the motor 15 is connected to the rotating shaft, so that the motor 15 outputs power to drive the first baffle 14.1 and the second baffle 14.2 to rotate around the rotating shaft.

[0048] The rotating plate bracket 16 is provided with a rotating plate slot 16.3 for placing the rotating shaft. The rotating plate bracket 16 is provided with a first rotating plate air inlet 16.1 and a second rotating plate air inlet 16.2 respectively corresponding to the rotating plate 14.

[0049] The airflow circulation assembly includes a high-speed fan duct 17, a high-speed fan assembly 18, a connecting frame 19, a base connector 20, a high-speed fan front shell 22, and a high-speed fan rear shell 23.

[0050] The high-speed fan assembly 18 is a conventional bladeless electric fan. The upper end of the high-speed fan assembly 18 is covered with the high-speed fan duct 17, and the lower end of the high-speed fan assembly 18 is connected to the base support plate 11 of the base assembly through the connecting frame 19.

[0051] The high-speed fan duct 17 is a horn structure with openings at the top and bottom. The upper end of the high-speed fan duct 17 is provided with a fan duct outlet 17.1, which is directly opposite to the rotating plate bracket 16. The lower end of the high-speed fan duct 17 is provided with a fan duct inlet 17.2, which is directly opposite to the output port of the high-speed fan assembly 18. The opening of the fan duct outlet 17.1 is smaller than the opening of the fan duct inlet 17.2, so that the airflow generated by the high-speed fan assembly 18 can be concentrated and output through the fan duct outlet 17.1.

[0052] A filter element assembly is also provided on the outside of the fan housing. The filter element assembly is composed of a front filter element 21 and a rear filter element 24 that are interlocked. Both the front filter element 21 and the rear filter element 24 are semi-cavity structures. The filter element assembly is used to filter impurities in the airflow, so as to prevent the high-speed fan assembly 18 from sucking in impurities during long-term use and causing functional failure, thereby improving its service life.

[0053] In this embodiment of the utility model, the shapes of the first long slit outlet 1.1, the middle air outlet 2.1 and the second long slit outlet 3.1 can also be selected according to actual application requirements, such as patterns with hollow effects or grille shapes.

[0054] The specific working principle of the bladeless heating and cooling device described in this embodiment of the utility model is as follows:

[0055] When the product starts working, the high-speed fan assembly 18 starts working, generating negative pressure, causing external air to enter through the first filter inlet 6.1 and the second filter inlet 10.1 on the front filter housing 6 and the rear filter housing 10. The air is then filtered into clean air through the front filter 21 and the rear filter 24, and further enters the product through the first fan housing inlet 22.1 and the second fan housing inlet 23.1 on the front fan housing 22 and the rear fan housing 23. It is then drawn into the high-speed fan assembly 18 and blown out by the high-speed fan assembly 18. It then passes through the fan duct inlet 17.2 of the high-speed fan duct 17. Due to the constriction structure of the high-speed fan duct 17, the air is gathered together, the airflow is strengthened, and it exits from the fan duct outlet 17.1. At this time, there are two situations:

[0056] Scenario 1: Combining Figure 2 , Figure 3 , Figure 6 As shown, when the heating element 12 is not working, the motor 15 controls the rotating plate 14 to rotate, so that the rotating plate 14 exposes the first rotating plate air inlet 16.1 of the rotating plate bracket 16, blocks the second rotating plate air inlet 16.2, and blocks the diversion hole 8.3 of the diversion air duct 8. The air can only flow from the exposed first rotating plate air inlet 16.1 to the first air column 1 and the third air column 3, and then blow out through the first long slit outlet 1.1 and the second long slit outlet 3.1 to achieve the purpose of generating cold air.

[0057] Scenario 2: Combining Figure 2 , Figure 4 , Figure 5 As shown, when the heating element 12 is working, the motor 15 controls the rotating plate 14 to rotate, so that the rotating plate 14 blocks the first rotating plate air inlet 16.1 of the rotating plate bracket 16, while the second rotating plate air inlet 16.2 is exposed. The diversion port of the diversion air duct 8 is blocked, so the air can only flow from the exposed second rotating plate air inlet 16.2 into the heating element bracket 13, and then blow onto the working heating element 12. After being heated, the hot air is blown out from the heating mounting groove 13.1 of the heating element bracket 13, and then blown out through the middle air outlet 2.1 to achieve the purpose of generating warm air.

[0058] In other embodiments of this utility model, the rotating plate 14 can also be two flat baffles. When the two baffles converge towards the middle, the air outlets on both sides are exposed, and the air outlet in the middle is closed. The air outlets on both sides can be connected to the cold air outlet (i.e., the first long slit outlet 1.1 and the second long slit outlet 3.1) respectively to achieve the purpose of cooling air. When they are laid flat on both sides, the air outlet in the middle is exposed, the air outlets on both sides are closed, and the hot air outlet (i.e., the middle air outlet 2.1) is connected to achieve the purpose of heating air. As long as the purpose of switching the air duct can be achieved, it is acceptable.

[0059] The bladeless heating and cooling heater of this utility model embodiment switches the air duct according to whether the heating element is working, thereby controlling the airflow path of the air circulation component. When the heating element is working, hot air is emitted from the middle air outlet 2.1, and when the heating element is not working, cold air is emitted from the cold air outlet. Not only can hot and cold air be switched, but the two are not in the same air duct, so they can have a better airflow at the same time, which improves the user experience.
