Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular 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

[0052] The airflow circulation assembly includes a high-speed fan duct 19, a high-speed fan assembly 20, a connecting frame 21, a base connector 22, a high-speed fan front shell 24, and a high-speed fan rear shell 25. Both the high-speed fan front shell 24 and the high-speed fan rear shell 25 are semi-cavity structures, and they are interlocked to form a fan housing. The fan housing is a hollow cavity structure, and it is arranged around the outside of the high-speed fan assembly 20. The high-speed fan front shell 24 has a first fan housing inlet 24.1, and the high-speed fan rear shell 25 has a second fan housing inlet 25.1.

[0056] In this embodiment of the present invention, the first opening 2.3 is shaped like a racetrack circle or a square opening. Correspondingly, the shape of the air outlet shell 3 matches the shape of the first opening 2.3, also being a racetrack circle or a square opening. The size of the air outlet shell 3 is slightly smaller than the size of the first opening 2.3, thereby forming a gap between the air outlet shell 3 and the first opening 2.3. This gap is the cold air outlet. In other embodiments of the present invention, the shape of the first opening 2.3 can also be selected according to actual application requirements, such as a pattern with a hollow effect or a grille shape.

[0057] The specific working principle of the bladeless heating and cooling device described in this embodiment of the utility model is as follows:

[0058] When the product starts working, the high-speed fan assembly 20 starts working, generating negative pressure, causing external air to enter through the first filter inlet 6.1 and the second filter inlet 11.1 on the front filter housing 6 and the rear filter housing 11. The air is then filtered into clean air through the front filter 23 and the rear filter 26, and further enters the product through the first fan housing inlet 24.1 and the second fan housing inlet 25.1 on the front fan housing 24 and the rear fan housing 25. It is then drawn into the high-speed fan assembly 20 and blown out by the high-speed fan assembly 20. It then passes through the fan duct inlet 19.2 of the high-speed fan duct 19. Due to the contraction structure of the high-speed fan duct 19, the air is gathered together, the wind force is strengthened, and it is discharged from the fan duct outlet 19.1. At this time, there are two situations:

[0059] Scenario 1: Combining Figure 2 , Figure 4 , Figure 6 As shown, when the heating element 13 is not working, the motor 17 controls the rotating plate 16 to rotate, so that the rotating plate 16 exposes the second rotating plate air inlet 18.2 of the rotating plate bracket 18, while blocking the first rotating plate air inlet 18.1 and the diversion hole 14.3 of the diversion air duct 14. The air can only flow from the exposed second rotating plate air inlet 18.2 into the cavity formed by the front shell, the rear shell, and the outer side of the heating element air duct 15 (i.e., the inner cavity of the air outlet front shell 2), and then blow out through the first long slit outlet 2.1 and the second long slit outlet 2.2, which are connected to the cavity, to achieve the purpose of generating cold air.

[0060] Scenario 2: Combining Figure 2 , Figure 3 , Figure 7 As shown, when the heating element 13 is working, the motor 17 controls the rotating plate 16 to rotate, so that the rotating plate 16 blocks the second rotating plate air inlet 18.2 of the rotating plate bracket 18, while the first rotating plate air inlet 18.1 leaks out. The diversion port of the diversion air duct 14 is blocked, so the air can only flow from the leaking first rotating plate air inlet 18.1 to the heating air duct air inlet 15.1 in the air duct cavity inside the heating element air duct 15, and then blow onto the working heating element 13. After being heated to obtain hot air, it is blown out from the heating air outlet 12.1 of the heating element bracket 12, and then blown out through the middle air outlet 3.1 to achieve the purpose of generating warm air.

[0061] In other embodiments of this utility model, the rotating plate 16 can also be two flat baffles. When the two baffles converge towards the middle, the air outlets on both sides are exposed, and the middle outlet is closed. The air outlets on both sides can be connected to the cold air outlet (i.e., the first long slit outlet 2.1 and the second long slit outlet 2.2) respectively to achieve the purpose of cooling air. When they are laid flat on both sides, the middle air outlet is exposed, the air outlets on both sides are closed, and the hot air outlet (i.e., the middle air outlet 3.1) 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.

[0062] 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 3.1, 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.

[0063] Numerous specific details are set forth in the specification provided herein. However, it will be understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0064] Similarly, it should be understood that, in order to simplify this disclosure and aid in understanding one or more of the various aspects of the invention, in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof. However, this method of disclosure should not be construed as reflecting an intention that the claimed invention requires more features than expressly recited in each claim. Rather, as reflected in the claims, the inventive aspect lies in fewer than all features of a single foregoing disclosed embodiment. Therefore, the claims following the detailed description are hereby expressly incorporated into that detailed description, wherein each claim itself is a separate embodiment of the invention.

[0065] It should be noted that the above embodiments are illustrative of the present invention and not restrictive of the present invention, and that those skilled in the art can devise alternative embodiments without departing from the scope of the appended claims.
