Problems solved by technology

However, for energy-saving stoves, in order to improve the utilization rate of heat energy, heat radiation plates are generally installed in the furnace cavity, which is not convenient for installing ignition pins. As in the prior art, the ignition needle is installed in the furnace cavity or on the shell of the furnace head. The ignition needle is easily burned and melted by the flame at high temperature, and the service life is very short.

Embodiment 1

[0023] An energy-saving stove provided with an ignition needle at the critical point of the flame in this embodiment includes a furnace body 1 , a burner head 2 located in the center of the inner cavity of the furnace body 1 , a gas pipe 3 communicating with the burner head 2 and an ignition needle 6 .

[0024] Such as figure 1 As shown, a stove 4 is installed on the top of the burner 2, and the stove 4 is shaped on a gas hole 4a communicating up and down, and the gas in the gas pipe 3 is ignited after being ejected from the gas hole 4a. The gas holes 4a are evenly distributed on the stove plate 4, preferably four to twelve, and the appropriate aperture size of the gas holes 4a can play the role of combing the gas and preventing tempering.

[0025] The lower part of the burner 2 is connected with a gas pipe 3, and the lower end of the gas pipe 3 is formed with an air inlet 3a for connecting with a blower fan 16. The gas pipe 3 at the air inlet 3a place is connected with a gas...

Embodiment 2

[0032] Such as figure 2 As shown, an energy-saving stove provided with an ignition needle at the critical point of the flame in this embodiment includes a furnace body 1, a burner head 2 located in the center of the inner cavity of the furnace body 1, a gas pipe 3 communicated with the burner head 2 and an ignition pin 6.

[0033] In the present embodiment, the structure of the burner 2, the gas pipe 3 and the ignition needle 6 is the same as that of the embodiment 1, except that the upper end of the furnace body 1 of the present embodiment forms a sealing support portion 1a which is sealed and connected with the bottom of the pot body, The pot body is installed on the sealing support part 1a, and a closed heating space is formed in the furnace body 1 .

[0034] Between the outer wall of the burner head 2 and the inner wall of the furnace body 1, a circular conical trapezoidal cover body 5 made of ceramic material is fixedly installed. The inner edge of the table-shaped cov...

Embodiment 3

[0037] Such as image 3 As shown, an energy-saving stove provided with an ignition needle at the critical point of the flame in this embodiment includes a furnace body 1, a burner head 2 located in the center of the inner cavity of the furnace body 1, a gas pipe 3, an ignition needle 6 and an eternal flame mixed gas Tube 8.

[0038]A stove 4 is installed on the top of the burner 2, and the stove 4 is shaped on a gas hole 4a communicating up and down, and the gas in the gas pipe 3 is ignited after being ejected from the gas hole 4a. The gas holes 4a are evenly distributed on the stove plate 4, preferably four to twelve, and the appropriate aperture size of the gas holes 4a can play the role of combing the gas and preventing tempering.

[0039] The lower part of the burner 2 is connected with a gas pipe 3, and the lower end of the gas pipe 3 is formed with an air inlet 3a for connecting with a blower fan 16. The gas pipe 3 at the air inlet 3a place is connected with a gas inle...

Abstract

The invention discloses an energy-saving stove with an ignition needle arranged at a flame critical point. The energy-saving stove comprises a stove body, a stove head and a gas pipe, wherein the stove head is arranged in the center of the inner chamber of the stove body and the gas pipe is communicated with the head. A stove plate with a gas hole is installed at the upper part of the stove head. A ring tapered platform mask body made of ceramic material is fixedly installed between the outer wall of the stove head and the inner wall of the stove body. The ignition needle is fixed in the gas pipe. The discharge tip of the ignition needle is arranged in the gas hole of the stove plate, or penetrates through the gas hole of the stove plate and is arranged between the upper surface of the stove plate and the erupted flame. The invention realizes the automatic ignition of the energy-saving stove. Since the ignition needle is arranged in the stove head and in the gas pipe and the discharge tip of the ignition needle is arranged above the gas hole of the stove plate and is lower than the critical point at the bottom of the flame, the ignition needle is prevented from being directly burnt by the flame and is continuously cooled by cold air sprayed by the gas pipe, and the service life of the ignition needle is effectively prolonged.

Description

technical field [0001] The invention relates to an energy-saving stove, in particular to an energy-saving stove with an ignition needle arranged at the critical point of the flame. Background technique [0002] In the existing stoves, the ignition needle is arranged in the furnace cavity or on the burner shell to ignite the gas emitted by the burner. However, for energy-saving stoves, in order to improve the utilization rate of heat energy, heat radiation plates are generally installed in the furnace cavity, which is not convenient for installing ignition pins. As in the prior art, the ignition pin is installed in the furnace cavity or on the shell of the burner head. The ignition pin is easily burned and melted by the flame at high temperature, and the service life is very short. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving stove with an ignition needle at the critical point of the flame, so...
