Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating equipment, in particular to a heater suitable for liquefied gas and natural gas. Background Art
[0002] A heater is a device used for heating. Based on the heating medium and heating principle, heating equipment can be broadly categorized as gas-fired, electric, boiler, and electric wall-mounted boilers. Gas-fired heaters work as follows: The burning gas heats the stainless steel mesh of the burner, rapidly turning red. This mesh heats the air, which circulates through the heated air through convection generated by the burning gas. Furthermore, the reddening of the mesh generates far-infrared radiation that heats surrounding objects.
[0003] The gas sources used in current gas heating equipment are natural gas and liquefied gas. Since natural gas and liquefied gas have different calorific values and pressures, the nozzle apertures of natural gas and liquefied gas are different under the same power. Therefore, when changing the gas source of traditional heaters, the nozzle must be replaced manually, which is inconvenient to use. Utility Model Content
[0004] In order to make up for the deficiencies in the prior art, the utility model provides a heater suitable for liquefied gas and natural gas, which can automatically adapt to the two gas sources and is convenient and safe to use.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A heater suitable for liquefied gas and natural gas includes a shell, in which a dual-source gas intake valve, an igniter, a control valve, and a combustion chamber are installed. A fire grate and an oxygen deficiency protector are arranged in the combustion chamber from top to bottom. The dual-source gas intake valve and the control valve, as well as the oxygen deficiency protector and the dual-source gas intake valve are connected respectively by gas pipelines. A temperature sensor is provided in the control valve, which can cut off the gas transmission when the indoor temperature reaches a preset value.
[0007] Furthermore, a heat insulation plate is provided above the fire bar in the combustion chamber.
[0008] Furthermore, the shell is provided with a window corresponding to the combustion chamber, and the window is connected to a protective net.
[0009] Furthermore, the shell is formed by a front shell and a rear plate that are detachably connected.
[0010] Furthermore, the dual-source air intake valve is connected to the front side of the rear plate via an air intake valve fixing plate, and the control valve is connected to the front side of the rear plate via a control valve fixing plate.
[0011] Furthermore, a hook and a ground wire are provided on the rear side of the rear plate.

[0016] The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] Example 1
[0018] like Figure 1 As shown, a heater suitable for liquefied gas and natural gas includes a housing formed by a detachable front shell 1 and a rear plate 2. A dual-source air inlet valve 3 is installed at the bottom of the housing, an igniter 4 and a control valve 5 are installed at the top, and a combustion chamber 6 is installed in the middle.
[0019] The dual-source air intake valve 3 is connected to the front side of the rear plate 2 via the air intake valve fixing plate 7, and the control valve 5 is connected to the front side of the rear plate 2 via the control valve fixing plate 8. A hook 9 and a ground wire 10 are provided on the rear side of the rear plate 2.
[0020] The combustion chamber 6 is equipped with a heat shield 11, a fire grate 12, and an oxygen-deficient protector 13 from top to bottom. Gas pipelines connect the dual-source air intake valve 3 to the control valve 5, and the oxygen-deficient protector 13 to the dual-source air intake valve 3. A temperature sensor is installed within the control valve 5, which cuts off gas flow when the indoor temperature reaches a preset value. The front housing 1 has a window corresponding to the combustion chamber 6, connected to a protective net 14.
[0021] When the utility model is in use, the knob of the control valve 5 is pressed and the igniter 4 is pressed at the same time, which can ignite the flame at the oxygen deficiency protector 13. Then, the knob of the control valve 5 is rotated to ignite the fire grate 12. The heat generated by the fire grate 12 is transferred to the room through the combustion chamber 6 to achieve the effect of heating.
[0022] The dual-source gas inlet valve 3 can be used as a combustion energy source to meet the needs of different regions; the dual-source gas inlet valve has two gas interfaces A and B, among which port A is a natural gas inlet and port B is a liquefied gas inlet. When in use, connect any one of the gas interfaces according to local conditions, and the other gas interface will be locked and closed and cannot be used; when the gas source is incorrectly connected to the interface, the fire grate and the oxygen deficiency protector cannot be ignited, and the heater will not work, thereby achieving the purpose of protecting safety.
[0023] The control valve 5 is equipped with a temperature sensor. When the temperature sensor senses that the indoor temperature has reached the preset temperature value, it will cut off the gas transmission and control the combustion of the fire grate, so that the overall temperature of the heater will not continue to rise, thereby achieving the purpose of protecting safety; when the temperature drops, the gas transmission channel will automatically open, and the fire grate will be reignited through the flame of the oxygen deficiency protector to generate heat for continued heating.
[0024] When the oxygen content in the room is insufficient, the flame of the oxygen deficiency protector will burn incompletely or go out. When the probe of the oxygen deficiency protector cannot detect the flame and does not meet the requirements of the protection device, the gas transmission is cut off through the control valve to prevent gas leakage and achieve the purpose of protecting safety.
[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
