[0018] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] As Figures 1 to 4 shown, the present utility model provides a multi-functional gas heating furnace, including a furnace body 20. Inside the furnace body 20, there are a water tank 1, several heating water pipes 2, a burner row 5, a hot air dry burning pipe 3, and an exhaust gas passage 24. At the top of the furnace body 20, there is a furnace opening, and a furnace cover 16 is covered on the furnace opening. The upper part of the heating water pipe 2 faces the furnace cover 16, and the lower part of the heating water pipe 2 faces the burner row 5, so that the flame outlet of the burner row 5 passes through the gap between every two heating water pipes 2, and the flame can directly heat the bottom of the pot. The side of the heating water pipe 2 is adjacent to the hot air dry burning pipe 3. The exhaust gas passage 24 is arranged above the side of the burner row 5. The water tank 1 is arranged around several heating water pipes 2. The two ends of several heating water pipes 2 are communicated with the water tank 1. The burner row 5 is connected to a gas pipe assembly. One end of the hot air dry burning pipe 3 is connected to a hot air blower 11, and the other end is connected to a hot air duct 25 leading to each room, or both ends of the hot air dry burning pipe 3 are connected to detachable plug caps 4. One of the hot air blower 11 and the detachable plug caps 4 is selected. The plug caps 4 are buckled at both ends of the hot air dry burning pipe 3 when heating is not required.

[0020] Specifically, the gas pipe assembly is composed of a flameout protection device 13, an ignition assembly 12, a gas joint 19, a gas pipe 21, and a gas leakage prevention solenoid valve 14 connected in sequence. The burner row 5 is connected to the flameout protection device 13, and the gas leakage prevention solenoid valve 14 is connected to a gas source 27, which can be connected to a liquefied gas tank or a natural gas pipeline. A panel 17 is installed on the front of the furnace body 20. The ignition assembly 12 and the gas joint 19 are fixed on the panel 17 of the furnace body 20. Oxygen supply and ventilation holes 23 communicating inside and outside the furnace body 20 are arranged at the lower part of the panel 17. The panel 17 is fixed on the furnace body through detachable fastening screws 18.

[0021] Furthermore, at the end of the exhaust gas passage 24, there are a first exhaust gas pipe 8 and a second exhaust gas pipe 9. The first exhaust gas pipe 8 is communicated with a kang inlet, and the second exhaust gas pipe 9 is communicated with a smoke exhaust pipe. A waste gas pipe conversion valve (26) is arranged between the first exhaust gas pipe 8 and the second exhaust gas pipe 9. When in use, one of the actual required forms is selected through the waste gas pipe conversion valve.

[0022] Further, a water supply pipe nipple 6 connected to a heating water supply pipe is provided at the upper end of the water tank 1, and a return water pipe nipple 7 connected to the heating water return pipe 22 is provided at the lower end of the water tank 1. A circulation pump 15 is provided on the heating water return pipe 22.

[0023] The hot air dry-burning pipe 3 is a hollow pipe, and the hollow pipe is horizontally inverted U-shaped and passes under the water tank 1. The heights of the air inlet and outlet at both ends of the hot air dry-burning pipe 3 are parallel to the lowest height of the hot air dry-burning pipe 3. That is, the air inlet and outlet of the hot air blower 11 are located at the lowest height position of the hot air dry-burning pipe 3. Since the cold air is under the room, it can cause the air in the room to convect, which is beneficial to quickly raising the indoor temperature.

[0024] An oxygen supply variable-frequency blower 10 is fixedly installed on the outer wall of the furnace body 20. The air outlet of the oxygen supply variable-frequency blower 10 is placed on the inner wall of the furnace body 20 and faces the opposite inner wall of the furnace body 20. The horizontal air duct formed by the oxygen supply variable-frequency blower 10 in the furnace body 20 is located below the burner row 5. The function of this setting is to make the air blow directly to the opposite side, not directly to the burner row 5, which can prevent the flame from being blown out by excessive air volume while supplying oxygen to the burner row 5.

[0025] The gap between the flame outlet of the burner row 5 and the heating water pipe 2 above it is opposite, so that the flame can directly heat the bottom of the pot.

[0026] The furnace cover 16 above the furnace opening is a movable furnace cover 16. When in use, the pot is placed on the furnace opening for cooking. When not cooking, the furnace cover 16 is covered.

[0027] The oxygen supply variable-frequency blower 10, the hot air blower 11 and the circulation pump 15 are prior arts and will not be described in detail. At the same time, the present invention also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are based on Figure 1 the direction shown in the drawing.

[0028] Turn on the switch of the gas source 27 and the ignition switch to light the burner 5, and then complete the operations of heating the room, providing hot air and cooking. This device uses a commercial high-power stove with more sufficient firepower. After the burner 5 is lit, it immediately heats the heating water pipe 2, the water tank 1 and the hot air dry-burning pipe 3. Since this utility model is made of stainless steel as a whole, the material is thinner than carbon steel and cast iron, and heats up faster. After the burner 5 is lit, turn on the oxygen supply variable-frequency fan 10 and the hot air supply fan 11. Hot air will blow out from the hot air dry-burning pipe 3 after heating for 1 - 2 minutes. The water in the water tank 1 will be heated to about 80 degrees in about 10 - 15 minutes. So, after heating for 15 minutes, the circulation pump can be turned on, and the water in the radiator can circulate normally. When the indoor temperature reaches the required level, the gas can be turned down or turned off, and at the same time, the circulation pump can be turned off. While heating the room, cooking and boiling water can be carried out. There is enough space between every two heating water pipes 2, and the flame can directly heat the bottom of the pot to achieve the purpose of cooking. When testing the heating of a 50-square-meter self-built house with 3 groups of 16-column radiators installed in the room, after heating for 1.5 - 2 hours, the water supply temperature of the radiator reaches about 80 degrees, the return water temperature reaches about 60 degrees, and the indoor temperature reaches 20 degrees. When the hot air supply function is turned on at the same time, the indoor temperature reaches about 24 degrees. The combined use of water heating and hot air has a very obvious effect and can improve the utilization rate of gas. If the house has good insulation, the indoor temperature will be higher. In the case of each family cooking three meals, the gas will be used for 1.5 - 3 hours. Using this heating stove will not increase the gas consumption too much. If it is used in the catering industry, basically the heating cost for the entire heating period can be saved, and there is no need to burn a small boiler by oneself, which truly plays the role of energy conservation and environmental protection. If there is already heating in the house, when installing this heating stove, just connect the inlet and outlet water pipes to use it. For geothermal, connect the inlet and outlet water pipes of the manifold. The first row of exhaust pipes 8 can use the original smoke exhaust pipe, and only 25 hot air pipes leading to each room need to be installed. When heating is not required, close the valves of the inlet and outlet water pipes and fasten the plug 4 of the hot air dry-burning pipe 3. When cooking, since the water tank 1 will also be heated at the same time, it can play the role of simmering or keeping warm.
