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

[0037] The upper end of the base assembly has a base opening 4.1, and the lower end of the air outlet assembly is disposed in the base opening 4.1. First long slit outlet 1.1, second long slit outlet 3.1, middle air outlet 2.1

[0038] The base assembly is made of engineering plastic and includes a base top cover 4, a base front shell 5, a base bottom cover 7, and a base rear shell 9. The base front shell 5 and the base rear shell 9 are both semi-cavity structures. The base front shell 5 and the base rear shell 9 are interlocked to form a base shell, which is a hollow cavity structure with openings at both ends.

[0039] The upper end of the base housing is provided with a base top cover 4, and the base top cover 4 is provided with the base opening;

[0040] The lower end of the base housing is provided with a base cover 7, which is used to provide physical support for other components;

[0041] The base assembly also includes a first filter element 18 and a second filter element 20. The outer side of the base front shell 5 is covered with the first filter element 18, and the outer side of the base rear shell 9 is covered with the second filter element 20.

[0042] Both the first filter element 18 and the second filter element 20 are conventional HEPA filters or activated carbon filters, used to filter impurities in the airflow, to prevent the components in the base assembly from absorbing impurities during long-term use and causing functional failures, thereby improving service life.

[0043] The outer side of the first filter element 18 is provided with a first filter element cover 6, and the first filter element cover 6 is provided with a plurality of first filter element air inlets 6.1;

[0044] The outer cover of the second filter element 20 is provided with a second filter element cover 8.

In this embodiment of the utility model, the heating element 11 is a conventional PTC heating element 11, which is used to generate heat by electric heating.

[0046] The air duct control assembly includes a diversion air duct 14, a rotating plate 12, and a motor 13. The diversion air duct 14 is disposed inside the top cover 4 of the base and has an air outlet 14.1 connected to the first air column 1, the second air column 2, and the third air column 3. The rotating plate 12 and the motor 13 are respectively disposed on the diversion air duct 14. The rotating plate 12 is a semi-circular structure with a rotating shaft (not shown), the long side of which is the rotating shaft, which is hinged to the diversion air duct 14. The output shaft of the motor 13 is connected to the diversion air duct 14. The rotating shaft is connected; the motor 13 can drive the rotating plate 12 to rotate relative to the diversion duct 14, thereby outputting power through the motor 13 to drive the rotating plate 12 to rotate around the rotating shaft. When the rotating plate 12 is on the left side, it blocks the connection between the second air column 2 and the airflow circulation component. At this time, the airflow circulation component is connected to the first air column 1 and the third air column 3. Correspondingly, when the rotating plate 12 is on the right side, the airflow circulation component is connected to the second air column 2, while blocking the first air column 1 and the third air column 3, thereby controlling the airflow in the duct.

[0047] The airflow circulation assembly includes a centrifugal fan assembly 16, a first air duct 15, a second air duct 17, and a base connector 19; the first air duct 15 and the second air duct 17 are both semi-cavity spiral structures, and the first air duct 15 and the second air duct 17 are interlocked to form a fan housing, which is a hollow cavity structure. The fan housing is arranged around the outside of the centrifugal fan assembly 16, and the fan housing is fixedly connected to the base assembly through the base connector 19.

[0048] The first air duct 15 has a first side air inlet 15.1 on its side, which is directly opposite the first base air inlet 5.1; the first air duct 15 has a first end air outlet 15.2 directly opposite the air outlet assembly.

[0049] The second air duct 17 has a second side air inlet 17.1 on its side, which is directly opposite the second base air inlet 9.1; the second air duct 17 has a second end air outlet 17.2 directly opposite the air outlet assembly.

[0050] The centrifugal fan assembly 16 is a conventional combination of a motor 13 and a centrifugal impeller. The centrifugal fan assembly 16 uses the first end air outlet 15.2 and the second end air outlet 17.2 as air outlet ports, and the first side air inlet 15.1 and the second side air inlet 17.1 as air inlet ports.

[0051] 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.

[0052] The specific working principle of the bladeless heating and cooling device described in this embodiment of the utility model is as follows:

[0053] When the product starts working, the centrifugal fan assembly 16 starts working, generating negative pressure, causing external air to enter through the first filter inlet 6.1 and the second filter inlet 8.1 on the first filter cover 6 and the second filter cover 8. The air is then filtered through the first filter element 18 and the second filter element 20 to become clean air, and then further enters the product through the first base inlet 5.1 and the second base inlet 9.1 on the front shell 5 and the rear shell 9 of the base, and is then blown out by the centrifugal fan through the first end outlet 15.2 and the second end outlet 17.2. At this time, there are two situations:

[0054] Scenario 1: Combining Figure 2 , Figure 3 , Figure 5As shown, when the heating element 11 is not working, the motor 13 controls the rotating plate 12 to rotate to the right, so that the rotating plate 12 blocks the right side of the air outlet 14.1 of the air duct. The air blown out by the centrifugal fan assembly 16 enters the first air column 1 and the third air column 3, and then is blown out through the first long slit outlet 1.1, the middle air outlet 2.1 and the second long slit outlet 3.1 to achieve the purpose of generating cold air.

[0055] Scenario 2: Combining Figure 2 , Figure 4 , Figure 6 As shown, when the heating element 11 is working, the motor 13 controls the rotating plate 12 to rotate to the left, so that the rotating plate 12 blocks the left side of the air outlet 14.1 of the air duct. The air blown out by the centrifugal fan assembly 16 enters the second air column 2 and then blows towards the working heating element 11. After being heated to obtain hot air, it is blown out from the heating air outlet of the heating element support 10, and then blown out through the middle air outlet 2.1 to achieve the purpose of generating warm air.

[0056] In other embodiments of this utility model, the rotating plate 12 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 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 middle air outlet 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.

[0057] 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. When the heating element is not working, cold air is emitted from both the cold air outlet and the middle air outlet 2.1. This not only achieves the switching between hot and cold air, but also ensures that the two are not in the same air duct, thus providing a better airflow and improving the user experience.

[0058] 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.

[0059] 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.

[0060] 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.
