Description

Technical Field

[0001] This utility model belongs to the field of heater technology and relates to an indoor gas heater that prevents impurities. Background Technology

[0002] A gas heater is a device that uses gas (such as natural gas, liquefied petroleum gas LPG, or propane) as fuel to generate heat for indoor or specific areas. It is commonly used in homes, offices, garages, or other places requiring temporary or supplemental heating. However, indoor environments often contain impurities such as hair and dust, which can enter the gas heater during combustion and cause unnecessary harm. Therefore, it is essential to design an indoor impurity-proof gas heater to effectively prevent impurities from entering. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an indoor gas heater that prevents impurities.

[0004] The objective of this utility model can be achieved through the following technical solution: An indoor gas heater with impurity prevention, comprising a shell body, characterized in that a mixing device for mixing and outputting gas is installed at the bottom of the shell body, an air inlet is provided at the bottom of the mixing device, a gas interface is provided on the side of the mixing device, a main gas pipe is connected to the top of the mixing device, several auxiliary gas pipes extend from the side of the main gas pipe, a heating zone is in front of the auxiliary gas pipes, a catalytic grille is installed in the heating zone, a protective grille is installed in front of the catalytic grille, and air blowing fan units are arranged above and below the outer side of the protective grille. The air blowing fan units are connected to a gas supply unit, which is installed above and below the heating zone. The gas supply unit includes an air intake device, which is installed on the back of the shell body and the air intake end of the air intake device is connected to the outside. The air intake device has two outlets at the top and bottom, which are connected to the air blowing fan units through air ducts.

[0005] The working principle of this utility model is as follows: Connect the gas interface to an external gas pipeline. When heating is required, turn on the heater switch. First, control the catalytic grid to preheat. After preheating, introduce the gas into the mixing device. At the same time, introduce the corresponding proportion of air into the gas inlet for premixing. Then, output the gas through the main gas pipe and deliver it to the catalytic grid through the auxiliary gas pipe to carry out the catalytic reaction and generate heat. During this period, the gas supply unit and the air blowing unit cooperate to continuously blow air. While assisting in the dissipation of heat, they can also form a convection layer outside the heating zone, effectively preventing hair, dust and other impurities from entering the heating zone.

[0006] A heat-conducting component is installed inside the duct at a position corresponding to the catalytic grille, with the bottom of the heat-conducting component installed at the edge of the catalytic grille.

[0007] With the above structure, the heat at the connection between the catalytic grille and the outer shell can be dissipated through the heat-conducting component, which can achieve a certain heat insulation effect. In addition, the heat dissipated by the air duct can be reused to make the air blown by the air blower unit have a certain temperature.

[0008] Dust screens are installed at both the air inlet and the inlet of the air intake device.

[0009] The above structure serves to prevent dust.

[0010] The air blowing unit is set at an angle to the outward.

[0011] The above structure facilitates gas convection.

[0012] A bracket is installed at the bottom of the main body of the outer shell.

[0013] The above structure serves to support, stabilize, and elevate the main body.

[0014] Compared with existing technologies, this indoor gas heater with impurity prevention has the following advantages: This utility model sets up a catalytic grille in conjunction with the gas pipeline to form a flameless structure, and heats the heater through thermal radiation. At the outlet, a blower unit is set up to form a convection protection layer, which can effectively prevent hair, dust and other impurities from entering the heater while ensuring the heating effect.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-3As shown, this indoor impurity-proof gas heater includes a main shell 1. A mixing device 2 for mixing and outputting gas is installed at the bottom of the main shell 1. An air inlet 3 is provided at the bottom of the mixing device 2, and a gas interface 4 is provided on the side of the mixing device 2. A main gas pipe 5 is connected to the top of the mixing device 2. Several auxiliary gas pipes 6 extend from the side of the main gas pipe 5. The heating zone is in front of the auxiliary gas pipes 6. A catalytic grille 7 is installed in the heating zone. A protective grille 8 is installed in front of the catalytic grille 7. Air blowing fan units 9 are arranged above and below the outer side of the protective grille 8. The air blowing fan units 9 are connected to a gas supply unit. The gas supply unit is installed above and below the heating zone. The gas supply unit includes an air intake device 10. The air intake device 10 is installed on the back of the main shell 1, and the air intake end of the air intake device 10 is connected to the outside. The air intake device 10 has two outlets at the top and bottom, and is connected to the air blowing fan unit 9 through a duct 11.

[0021] In this utility model, the mixing device 2 is a commonly used component in existing flameless gas heaters. It is mainly responsible for mixing gas (propane / natural gas) with air in the optimal ratio to ensure the efficiency and safety of catalytic combustion or infrared combustion. The mixing device 2 is equipped with electrically controlled valves at both the air inlet 3 and the gas interface 4.

[0022] In this invention, the catalytic grid 7 adopts a catalytic reaction bed product commonly used in existing flameless gas heaters. It oxidizes and releases heat at a low temperature without producing a flame, directly releasing infrared radiation heat. Furthermore, it contains a resistance wire that can briefly heat the catalytic bed to approximately 100-150°C, allowing the catalyst to reach its operating temperature.

[0023] The air blowing fan unit in this utility model consists of multiple air blowing fans installed side by side.

[0024] In this utility model, the air intake device 10 adopts an existing air intake fan structure product and is used to draw in air.

[0025] A heat-conducting component 12 is installed inside the duct 11 at a position corresponding to the catalytic grille 7, with the bottom of the heat-conducting component 12 installed at the edge of the catalytic grille 7.

[0026] In this invention, the heat-conducting component 12 is fin-shaped and adopts a copper-base aluminum-fin structure to increase heat conduction and heat dissipation performance.

[0027] Dustproof nets 13 are installed at the inlet of both the air inlet 3 and the air intake device 10.

[0028] The air blower unit 9 is set at an angle to the outward.

[0029] A bracket 14 is installed at the bottom of the outer shell body 1.

[0030] The working principle of this utility model is as follows: The gas interface 4 is connected to an external gas pipeline. When heating is required, the heater switch is turned on. First, the catalytic grille 7 is controlled to preheat. After preheating, the gas is introduced into the mixing device 2. At the same time, air of the appropriate proportion is introduced into the gas inlet 3 for premixing. Then, the gas is output through the main gas pipe 5 and delivered to the catalytic grille 7 through the auxiliary gas pipe 6 to generate heat through catalytic reaction. During this period, the gas supply unit and the air blowing fan unit 9 work together to continuously blow air. While assisting in the dissipation of heat, a convection layer is formed outside the heating zone, which effectively prevents hair, dust and other impurities from entering the heating zone.

[0031] In this invention, the various mechanisms are connected and driven using existing technologies, and synchronous control is achieved through a control panel.

[0032] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
