DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0029] The principle of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0030] A single-control heating air outlet device, such as Figure 1-7 As shown, it includes an air duct 1, an air outlet grille 2 and a sealing plate 3. The air inlet side of the air duct 1 is connected to the air duct of the central air conditioning system, and the air outlet side is connected to the sealing plate 3. An air outlet is opened in the middle of the sealing plate 3, and the air outlet grille 2 is installed in the air outlet. The four corners of the sealing plate 3 are fixed with suspension rod connectors 31, which can be suspended under the roof through the suspension rod. A heating cylinder 4 is installed in the air duct 1, and the heating cylinder 4 divides the space enclosed by the air duct 1 into a circular air duct 11 in the middle and an annular air duct 12 on the periphery. A fan 5 is provided between the heating cylinder 4 and the air outlet grille 2. By adding a heating cylinder 4, the single-control heating and air outlet device can provide heating for the area where it is located separately, without the need to purchase an additional heater.

[0031] In this embodiment, the heating tube 4 is designed based on the electromagnetic heating principle, with high heating efficiency, energy saving and environmental protection. The heating tube 4 is composed of a coil 40, a cylindrical coil frame 41, a crystallized ceramic lining 42 and a heating element 44. The coil frame 41 is cylindrical, and the coil frame 41 extends radially outward to be fixedly connected to the air duct 1 with a plurality of mounting arms 45. The coil 40 is wound around the outer circumference of the coil frame 41, and the crystallized ceramic lining 42 is fixedly arranged on the inner circumference of the coil frame 41. The heating element 44 is made of brazed steel plate around the edge, and is fixedly arranged on the inner circumference of the crystallized ceramic lining 42. The surface of the steel plate is coated with a heat-resistant Teflon layer to prevent the steel plate from being oxidized and to prevent dust from adhering. The inner ring of the heating element 44 is provided with a guide strip 441 to increase the contact area with the airflow. After the airflow enters the air duct 1, it is divided into the circular air duct 11 and the annular air duct 12, and then re-converges at the location of the fan 5, and finally discharged from the air outlet grille 2.

[0032] In this embodiment, the coil frame 41 includes a front ring plate 411 and a rear ring plate 412, and the front ring plate 411 and the rear ring plate 412 are connected by a circle of support plates 413 arranged in a ring shape. The front ring plate 411 is located on the side close to the air outlet, and the coil 40 is wound on the annular surface formed by the support plates 413. The gap between the support plates 413 is more conducive to the heat dissipation of the crystallized ceramic lining 42 and the coil.

[0033] In this embodiment, the front end of the crystallized ceramic liner 42 is provided with a front plate 421, and the rear end is provided with a rear plate 422.

The coil frame 41 is nested in the outer cavity 423, and the heating element 44 is nested in the inner cavity 424. The crystallized ceramic liner 42, the coil frame 41 and the heating element 44 are nested and connected, which can prevent the crystallized ceramic liner 42 from being damaged due to stress changes during heating and cooling.

[0034] In this embodiment, the coil frame 41 is also provided with a group of ferrite flat magnetic strips 43 arranged in a ring shape. The ferrite flat magnetic strips 43 extend axially along the coil frame 41 and are tightly attached to the periphery of the coil. The ferrite flat magnetic strips 43 can absorb magnetic energy, thereby reducing the noise and heat generated by the ferromagnetic resonance of the heating tube 4, thereby improving efficiency and reducing power consumption.

[0035] In this embodiment, a reflective aluminum foil layer 13 is provided on the inner wall of the air duct 1 , and the reflective aluminum foil layer 13 can reflect heat radiation toward the middle of the air duct 1 . An aluminum silicate fireproof board 14 is also provided between the reflective aluminum foil layer 13 and the iron plate of the air duct 1 .

[0036] In this embodiment, a hollow hemispherical cover 6 protruding outward is provided in the middle of the air outlet grille 2, a motor frame 61 is provided inside the hemispherical cover 6, the motor frame 61 is used to fix the motor 51 of the fan 5, and a control circuit board 7 is fixed at the bottom of the motor frame 61. The hemispherical cover 6 is away from the heating cylinder 4, which can prevent the environment around the motor 51 and the control circuit board 7 from overheating and affecting the service life, and also has an aesthetic effect.

[0037] In this embodiment, the hemispherical cover 6 is provided with ventilation holes 62, and the control circuit board 7 is also provided with a negative ion generating circuit, which purifies the environment through negative ion wind and promotes human health.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
