Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a heating device and a control method thereof. BACKGROUND

[0002] At present, the warmer is widely used in the field of indoor heating. It generates heat through electric heating elements and uses natural convection or radiation to raise the room temperature. However, the surface temperature of the existing warmer can rise to above 70°C after a long time of operation, and users, especially children or pets, are extremely easy to be scalded when contacting it. Moreover, the residual heat of the heating element is not dissipated in time after the warmer is shut down, resulting in that the cabinet is in a high temperature state for a long time, and users face a high safety risk when storing or moving the device. SUMMARY

[0003] Therefore, the present application provides a heating device and a control method thereof to solve the problem of high surface temperature and high safety risk of the existing heating device.

[0004] In a first aspect, the present application provides a heating device, comprising: a warmer; a protective cover, which is provided in a hollowed-out manner and covers the warmer outside; a fan, which is arranged in the protective cover and is used for heat dissipation and / or acceleration of hot air circulation of the warmer. Advantages: the physical isolation is formed by the protective cover arranged outside the warmer, which prevents the user from being scalded by directly contacting the high-temperature surface of the warmer. In addition, the protective cover is designed in a hollowed-out manner, and the airflow can pass freely without affecting the normal heating effect of the warmer. Furthermore, the fan arranged in the protective cover can continue to move for a period of time after the warmer is turned off, actively dissipating heat from the warmer, so that the cabinet of the warmer cools down quickly, avoiding the problem of residual heat accumulation and not being dissipated in time, and improving the safety of the heating device. When the warmer is working, the fan can be controlled to run synchronously, which improves the air flow speed, accelerates the circulation of hot air, and speeds up the room temperature rising efficiency, so that the user has a better experience. The present embodiment provides a structure design which can effectively prevent the user from being scalded and achieve rapid heat dissipation, which not only solves the problem of high surface temperature and high safety risk of the existing heating device, but also improves the working efficiency and user experience of the heating device.

[0005] In an optional embodiment, the warmer comprises a cabinet and a heating body arranged in the cabinet, and the fan is arranged corresponding to the heating body.

[0006] Beneficial effects: By setting the fan corresponding to the heating body, the high-temperature air generated by the heating body can be blown away in the first time, avoiding the accumulation of hot air around the heating body to form a "heat barrier", realizing the combination of natural convection and forced convection of the fan, greatly improving the heat transfer efficiency of the heating body to the environment space, and improving the heating efficiency. Moreover, the fan is directly opposite to the heating body, and after the heating body is turned off, the fan directly forces air cooling on the heating body and its surrounding elements (such as the machine shell and the wire), which can quickly take away the huge amount of heat accumulated, effectively preventing the heating body and its surrounding elements from aging, damaging or even causing fire due to long-time high-temperature work, and reducing the risk of user scalding due to overheating of the machine shell when storing or moving the heating device.

[0007] In an alternative embodiment, the heating body is installed at the bottom position of the machine shell, and the fan is correspondingly arranged at the bottom position of the protective cover.

[0016] In an optional embodiment, the protective upper shell is provided with a first magnetic member, and the protective lower shell is provided with a second magnetic member corresponding to the first magnetic member, and the first magnetic member and the second magnetic member are attracted to each other. Along the length direction of the protective cover, two groups of the first magnetic members and the second magnetic members are correspondingly arranged at the two ends of the protective upper shell and the protective lower shell.

[0017] Beneficial effects: By arranging two groups of the first magnetic members and the second magnetic members at the two ends of the protective upper shell and the protective lower shell, the protective upper shell and the protective lower shell can be accurately docked, and the stability and reliability of the connection between the protective upper shell and the protective lower shell are further improved.

[0018] In an optional embodiment, the bottom of the warmer is provided with a supporting leg, and the protective lower shell is provided with an avoiding opening corresponding to the supporting leg.

Beneficial effects: By clamping the buckle on the protective lower shell and the clamping groove on the shell of the warmer, the protective cover and the warmer can be quickly disassembled and fixed, and since the buckle has a certain extension length, the safety distance between the entire protective cover and the shell of the warmer can be maintained.

[0021] In a second aspect, the present application further provides a control method of the heating device suitable for any of the above-mentioned embodiments, and the control method comprises: When receiving the device opening instruction, the heating body and the fan of the warmer are simultaneously started to enhance the hot air circulation; When receiving the device closing instruction, the heating body is stopped, and the fan continues to run according to the detected shell temperature of the warmer or the preset delay condition until the shell temperature decreases to the preset safety temperature.

[0022] Beneficial effects: When the user opens the device, the heating body and the fan are simultaneously started to enhance the hot air circulation and realize rapid heating; when the user closes the device, the heating body is stopped, and the fan continues to run according to the temperature information detected by the temperature sensor or the preset delay time until the shell temperature decreases to the safety threshold, thereby avoiding the problem of scalding the user due to the accumulation of residual heat and improving the safety of the heating device.

The existing heater design lacks effective heat insulation or active cooling mechanism, and only relies on natural cooling, which is low in efficiency and has prominent safety hazards. Some improved schemes can alleviate some problems by increasing the heat insulation layer, but cannot solve the problem of residual heat accumulation after shutdown, meet the user's demand for rapid cooling, and the user experience is poor.
