DETAILED DESCRIPTION

[0032] To make the purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0033] Reference Figs. 1-6 , shows a structure schematic diagram of a warmer, which can specifically include: a first heating element 206 arranged at the upper end and a second heating element 202 arranged at the lower end, and a blowing mechanism for air flow outward is arranged at the position of the second heating element 202 at the lower end, which is preferably a fan 203, and specifically an adjustable speed fan can be used. The double-zone coupled heating frame of the present application adopts the upper and lower double heating elements and fan active air supply technology, breaks through the heat hysteresis effect (multiple heating energy consumption problem) of the traditional single heat source equipment, realizes the dynamic balance of the heat field through the top direct heating and the bottom convection, and the heat coverage area can be greatly improved compared with the traditional warmer (under the premise of the same power consumption).

[0034] In the embodiment of the present application, a cylindrical shell 101 is further included; the first heating element 206 is arranged at the upper end position in the cylindrical shell 101, and the second heating element 202 is arranged at the lower end of the cylindrical shell 101; the bottom of the cylindrical shell 101 is further provided with a wind guide base 102, the middle of the wind guide base 102 is provided with a conical protrusion 121, and the edge position is provided with a support arm 122, the support arm 122 is connected to the bottom of the cylindrical shell 101, and the position of the cylindrical shell 101 at the lower end of the first heating element 206 is further provided with an air inlet hole 141. The side of the above-mentioned cylindrical shell 101 is symmetrically provided with a handle hole 104, and the handle hole position is provided with an air inlet hole 141; the above-mentioned air inlet hole 141 is arranged at the lower end of the first heating element 206 and the upper end of the second heating element 202, on the one hand, the handle hole 104 position is used as an air inlet position, so that the middle part of the warmer itself will not be overheated, and the carrying is convenient, on the other hand, the airflow is mainly downward through the upper end fan 203, and is dispersed to the surrounding through the wind guide base 102, and because the hot air quality is relatively light, it will move upward, which is equivalent to that the hot airflow from the bottom of the warmer can automatically spread from bottom to top, in addition, the first heating element 206 at the upper end can be heated alone, further improving the heat efficiency and heating effect. The compact structure of the present application saves space, the wind guide base optimizes the airflow path, and reduces heat loss. Ensure that the air supply is sufficient during the heating process, avoid overheating of the equipment, and at the same time, improve the heat exchange efficiency. At the same time, the upper and lower heating elements are arranged at both ends of the shell, which is convenient for maintenance and component replacement of the warmer.

[0035] In the following, one of the embodiments in the present example will be described.

[0036] In an embodiment of the present application, the side of the cylindrical shell 101 is symmetrically provided with a handle hole 104, and the handle hole 104 is internally provided with a partition groove 140; the partition groove 140 is internally provided with an air inlet hole 141, and the cylindrical shell 101 is further internally provided with a conical cylinder 204; the second heating element 202 is located at the bottom of the conical cylinder 204, and the height of the conical cylinder 204 is not higher than the position of the air inlet hole 141. Through the combination of the handle hole 104 and the air inlet hole 141, the additional opening is reduced, the structure is simplified, and the aesthetic appearance is enhanced. Secondly, the symmetrical layout of the air inlet hole ensures that the air is uniformly sucked in, avoiding noise or uneven heating caused by single-sided airflow disturbance. The height of the above-mentioned conical cylinder 204 does not exceed the air inlet hole, preventing the bottom hot air from flowing back and reducing heat loss. A heat insulation support frame 205 is further installed at the upper end inside the cylindrical shell 101, and the above-mentioned first heating element 206 is installed on the above-mentioned support frame 205, which plays a partitioning role, preventing heat conduction to the cylindrical shell 101, so that more heat is radiated upward, improving the heat utilization rate.

[0037] As an example, the upper end of the first heating element 206 is provided with a baking tray 105. The baking tray 105 increases the versatility of the warmer (e.g. food preservation, clothes drying), and improves the added value of the product. In addition, the first heating element 206 can also utilize the residual heat to improve energy utilization efficiency. The first heating element 206 can be an electromagnetic heater, as shown in the drawings, and the side of the baking tray 105 can also be provided with air holes 151 to allow heat to spread outward from all directions. Figs. 1 to 3

[0038] Further, as shown in the drawings, the outer side of the baking tray 105 is provided with an upwardly raised rim 106. The raised rim 106 prevents liquids or small objects from sliding off and enhances safety. The rim 106 forms a semi-closed space, reducing heat loss and improving local heating efficiency. Figs. 4 to 6

[0039] Further, the lower end of the rim 106 is connected to an annular transparent cover, the lower end of the transparent cover is connected to the cylindrical shell 101, and the transparent cover is provided with a flame simulator. The flame simulator combined with the transparent cover simulates the visual effect of a real fire, enhancing the scene atmosphere (e.g. camping, home decoration); in addition, the transparent cover prevents users from directly contacting the heating element, reducing the risk of burns.

[0040] The cylindrical shell 101 includes a baffle 111 and a light-transmitting plate 112 connected to the baffle 111.

[0041] The light-transmitting plate 112 is provided with an atmosphere lamp and / or a charcoal fire simulator, and the atmosphere lamp and the charcoal fire simulator are electrically connected to a main control board 301 provided on a bottom cover 201, and a second heating element 202 and a fan 203 are fixed to the bottom cover 201. The upper end of the bottom cover 201 is connected to the cylindrical shell 101 and a conical cylinder 204, and the main control board 301 is located in the space between the cylindrical shell 101 and the conical cylinder 204. The cylindrical shell 101 is composed of two baffles 111 and two light-transmitting plates 112, wherein the edges of the baffles 111 and the edges of the light-transmitting plates 112 coincide and are connected, for example, by a buckle and slot connection, or by a screw connection. The handle hole 104 is located on the baffle 111.

[0042] ​​The heating device is provided with the baking tray 105, which facilitates heating and cooking operation; the baking tray 105 and cooking tools such as a baking net are arranged on the top of the heating device, different cooking functions can be realized, an accommodating space is formed inside, an atmosphere lamp and a charcoal fire simulator and related components are installed, light effects and effects of simulating charcoal fire burning can be realized, on one hand, the main control board 301 can be used for controlling, brightness simulated by the charcoal fire simulator can be adjusted according to temperature, or light can be controlled, on the other hand, whether the heating device is in working state can be directly judged according to brightness simulated by the charcoal fire simulator and / or the atmosphere lamp; the light-transmitting plate 112 connected to the baffle 111 by a detachable and splicing structure can realize light transmission and facilitate disassembly and assembly, facilitate maintenance of internal functional structures, and effectively reduce production cost. The application has the functions of heating, cooking, light and music, and can realize various cooking functions, has high practicability, is convenient to disassemble and assemble, and effectively reduces production cost.

[0043] The atmosphere lamp provides various light effect modes (such as warm light and color light), and meets different scene requirements (such as festivals and leisure). The light-transmitting plate 112 is combined with light to improve product appearance attraction and differentiate market competition.

[0044] It should be noted that the flame simulator is a charcoal fire simulator, which is also commonly known as charcoal fire simulation, and is mainly divided into two types. One is to use LED light source combined with optical devices and projection technology. The LED lamp emits light, which is reflected and projected by high-precision optical devices to form a realistic flame image. This technology combines optical, mechanical and electronic technologies to simulate highly realistic flame effects. The other is to use an electric heating element (such as a resistance wire) to generate heat, which heats specially designed materials (such as quartz tubes or ceramic fibers) to simulate flame effects. When current passes through the resistance wire, heat is generated, which makes the material emit red light to simulate real flames. In order to enhance the flame effect, the simulated charcoal fire can be equipped with a fan and sound. The fan can enhance air flow, making heat and light better dissipate, while simulating the effect of wind blowing through wood, making the flame look more lively. In the present application, the LED light source combined with optical devices is preferably used as the charcoal fire simulator.

[0045] Further, the lower end of the second heating element 202 is also provided with a temperature controller, which can be an NTC resistor (not shown in the figure); the NTC resistor is used to monitor the temperature in real time and adjust the power to avoid overheating risk and prolong the service life of the device. The output can be automatically adjusted according to the ambient temperature to reduce invalid heating. The second heating element 202 can be preferably a PTC ceramic, which has a sudden increase in resistance with temperature rise, automatically limits current and keeps temperature constant, saves external temperature control device, reduces power when overheating, eliminates overheating risk, has low power consumption in constant temperature stage, and is more energy-saving than traditional heating elements; it is hot as soon as the low initial resistance is powered on, and responds quickly. Due to the non-oxidizing structure, it has the advantages of corrosion resistance, strong stability and maintenance-free.

[0046] A touch screen 302 is arranged at the lower end of the light-transmitting plate 112 and is electrically connected to the main control board 301, and has the same curvature as the light-transmitting plate 112, and is used to control the operation of the above-described warmer and display parameters and the like.

[0047] The cylindrical shell 101 is symmetrically provided with a handle hole 104 at the lower end of the first heating element, and the handle hole 104 is internally provided with a partition groove 140, and the partition groove 140 is provided with an air inlet hole 141. The partition groove 140 structure reduces the dust entering the inside of the equipment through the air inlet hole 141, and reduces the maintenance frequency. The partition groove 140 has a certain depth and the handle hole 104 forms a structure that is easy to carry and move. The air outlet opposite to the conical protrusion 121 of the air guide base 102 of the above-mentioned bottom cover 201 is a horn air outlet 103, so that the end of the bottom air outlet is not less than the position of the second heating element 202, avoiding the formation of gas compression phenomenon during the process of the fan 203 blowing hot gas flow from the bottom, and maintaining the output gas temperature.
