[0027] like Figures 1 to 4 As shown, the table-type return air hot stove provided in this embodiment has a working principle as follows:

[0028] 1. The name, serial number and function of each accessory are as follows:

[0029] 1. Dining table panel 10: It can be in various shapes. The material can be iron plate + steel plate with high temperature paint or iron plate + high temperature liquid crystal panel. There is a furnace core hole in the middle. The furnace core hole is the flame burning port, which is used for hot dishes, hot pot, etc. This furnace core hole is provided with a step for covering the flame through the furnace core cover 20, and the flame will burn back in the furnace core 31. The large heat energy will be emitted through the furnace body, and the whole house will be warm like floor heating.

[0030] 2. Furnace core cover 20: It is divided into three layers, used to cover the furnace core 31 on the dining table and block the flame from burning out of the table, and has the function of returning the flame along the furnace core 31 to the furnace barrel 30. In this way, heat energy can be radiated from the ground and spread throughout the room, making the whole house warm like floor heating.

[0031] 3. Furnace body barrel 30 : It contains furnace core 31 , can be connected to dining table panel 10 on the top, and can be connected to table bottom panel 40 on the bottom. The main function of furnace body barrel 30 is to keep warm and support dining table panel 10 .

[0032] 4. Table bottom panel 40: A through hole is provided in the middle, and three ears are provided in the through hole for connecting the furnace barrel 30.

[0033] 5. Ignition needle 317: installed on the lower back of the table bottom panel 40, connected to the stove pulse igniter 421 for ignition.

[0034] 6. Fire regulator 422: Installed at the front end of the "U"-shaped opening of the fuel tank, it is mainly used for fire power adjustment and ignition. Just turn the gear slightly to ignite and adjust the fire power.

[0035] 7. Stove pulse igniter 421: installed inside the front end of the "U"-shaped opening of the oil tank and connected to the fire regulator 422 for use.

[0036] 8. Wire 41: connected to the ignition needle 317 at the front and to the stove pulse igniter 421 at the back for current transmission.

[0037] 9. Oil pump 43: installed on the bottom frame, mainly used for pumping oil and transporting oil to the furnace core 31.

[0038] 10. Furnace core 31: Installed on the bottom bracket provided in the hole of the bottom panel of the table, the furnace core 31 is composed of a bucket-shaped base 311, an air inlet 312, a heat conducting pipe 318, and a conical ignition tube 313, which is the core of the whole product. The bucket-shaped base 311 is used to place the methanol fuel delivered, and the conical ignition tube 313 is provided with an oil inlet 3132 at the bottom. After ignition, the flame can be reduced to burn from the flame combustion delivery port 3131 on the conical ignition tube 313. The air inlet 312 is used to supply air, and the flame will not be extinguished even if the tabletop is closed and covered. The air inlet 3121 provided on the air inlet 312 has a return air function. The heat conducting pipe 318 is used for heat conduction. When the temperature is too low, the oil temperature can be kept from solidifying, so as to prevent the methanol fuel from solidifying due to the low temperature and failing to ignite.

[0039] 11. Fire extractor 314: It is installed on the conical fire guide 313 provided on the furnace core 31. The lower end is set in a trumpet shape, which is convenient for installation and fixation on the conical fire guide 313, and the upper end is a straight cylinder. It is mainly used to extend the flame to the surface for combustion. Since the air inlet 3121 is provided in the middle of the bottom of the furnace core 31, and the fire extractor 314 is effective, the flame is pulled to the fire outlet on the fire extractor 314 for combustion, which is called liquid surface combustion. Liquid surface combustion can increase the temperature to 400℃.
