Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to an infrared gas stove. Background Technology

[0002] Conventional gas stoves have open pot supports, as shown in the picture below. When cooking, overflowing liquids will flow from the edge of the pot down onto the pot supports, the drip tray, and the burner, making them inconvenient to clean. In addition, the burner and pot supports are relatively high, which is not aesthetically pleasing.

[0003] Infrared stoves primarily transfer heat through thermal radiation. The combustion plate reaches a surface temperature of nearly 1000℃. Since thermal radiation is proportional to the fourth power of temperature, the combustion plate radiates a significant amount of heat into or out of the burner head during combustion, resulting in a high temperature rise in the burner head. However, it also loses a considerable amount of heat, thus limiting the improvement of the thermal efficiency of infrared stoves. Summary of the Invention

The components of the embodiments of this utility model can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0031] Example:

[0032] like Figure 1-3 As shown, an infrared gas stove includes:

[0033] Stove body 1;

[0034] Burner 2 is located inside the stove body 1. A premixing chamber 21 is defined inside the burner 2, and an infrared burner 22 is covered on the premixing chamber 21.

[0035] A flow-guiding heat insulation plate 3 is disposed in the premixing chamber 21. Several through holes 31 for the mixed gas to pass through are opened on the flow-guiding heat insulation plate 3. The outer edge of the flow-guiding heat insulation plate 3 is connected to the upper wall of the premixing chamber 21 to jointly define the heat insulation chamber 211.

[0036] The first heat insulation component 4 is disposed inside the heat insulation cavity 211;

[0037] Support plate 5 is installed on the stove body 1 and is located on the outside of the burner head 2.

[0038] The second heat insulation element 6 is disposed on the inner side wall of the support plate 5;

[0039] Liquid collection tray 7 is mounted on support plate 5.

[0040] In this embodiment, the burner head 2 is disposed inside the stove body 1, and a premixing chamber 21 is defined inside the burner head 2. An infrared burner 22 is covered at the upper end of the premixing chamber 21. A flow-guiding heat insulation plate 3 is disposed inside the premixing chamber 21, and several through holes 31 are opened on the flow-guiding heat insulation plate 3 to allow the premixing chamber 21 to be interconnected vertically. In this way, the flow-guiding heat insulation plate 3 can block most of the heat radiated from the lower side of the infrared burner 22 to the burner head 2, thereby reducing the temperature rise of the burner head 2 and the inside of the stove. The outer edge of the flow-guiding heat insulation plate 3 is connected to the upper wall of the premixing chamber 21 to jointly define the heat insulation chamber 211. A first heat insulation element 4 is disposed inside the heat insulation chamber 211. The action of the premixing chamber 21 in conjunction with the upper wall further blocks some of the heat transferred downward or horizontally, greatly reducing the temperature of the lower part of the entire burner assembly. This is the internal heat insulation of the burner. A support plate 5 is provided on the stove body 1, and the support plate 5 is located on the outside of the burner head 2. A second heat insulation element 6 is provided on the inner side wall of the support plate 5. This effectively blocks the heat radiated from the bottom of the burner to the surroundings. This is the external heat insulation of the burner. Thus, by providing multiple heat insulation structures on the burner head 2, the temperature of the stove panel and internal components is kept within a safe range. Its structure is simple and can reduce the heat loss of the infrared burner 22, thereby improving the thermal efficiency of the infrared burner.

[0041] Furthermore, it also includes a bottom heat insulation plate 8, within which a receiving cavity is defined, and the lower end of the burner head 2 is disposed within the receiving cavity.

[0042] In this embodiment, the bottom heat insulation plate 8 has a bottom plate and side plates. The side plates are respectively located at the circumferential edge of the bottom plate, so that a receiving cavity is defined in the internal space of the bottom heat insulation plate 8. Then, the lower end of the burner head 2 is recessed in the receiving cavity, thereby effectively blocking the bottom of the burner head 2 from radiating heat to the surroundings.

[0043] Preferably, it also includes a pot support assembly 9, which is disposed on the panel of the stove body 1.

[0044] Specifically, the pot support assembly 9 includes a base 91, a support frame 92, and a heat-conducting plate 93. The base 91 is set on the panel of the stove body 1, and the lower end of the base 91 is correspondingly set with the liquid tray 7. The support frame 92 is set on the base 91, and the heat-conducting plate 93 is installed on the base 91 through the support frame 92, so that a smoke vent 94 is formed between the bottom wall of the heat-conducting plate 93 and the top wall of the base 91 or between the bottom wall of the support frame 92 and the top wall of the base 91.

[0045] Preferably, the height of the upper wall of the base 91 is lower than the height of the upper wall of the heat-conducting plate 93.

[0046] Furthermore, the projected area of ​​the heat-conducting plate 93 is greater than the projected area of ​​the base 91, or the projected area of ​​the heat-conducting plate 93 is greater than the projected area of ​​the burner head 2.

[0047] In this embodiment, an opening is provided on the panel of the stove body 1, and the burner 2 is set at the opening of the stove body 1. First, the liquid tray 7 is fitted onto the outer edge of the opening of the stove body 1, and then the base 91 is fitted onto the outer edge of the opening of the stove body 1. Thus, the upper end of the base 91 is pressed against the top wall of the liquid tray 7, and the lower end of the base 91 is correspondingly set with the liquid tray 7. The support frame 92 is set on the base 91, and the heat conduction plate 93 is installed on the base 91 through the support frame 92, so that a smoke vent 94 is formed between the bottom wall of the heat conduction plate 93 and the top wall of the base 91 or between the bottom wall of the support frame 92 and the top wall of the base 91. The high-temperature flue gas generated by the combustion of gas on the infrared burner 22 is discharged out through the smoke vent 94, thereby heating the cookware, that is, performing convective heat transfer on the cookware. Furthermore, the projected area of ​​the heat-conducting plate 93 is larger than the projected area of ​​the base 91, or the projected area of ​​the heat-conducting plate 93 is larger than the projected area of ​​the burner head 2, thereby effectively blocking the overflow liquid from flowing to the pot support base 91 and the burner area. That is, the diameter of the heat-conducting plate 93 is larger than the diameter of the base 91 and the diameter of the opening of the burner head 2, which facilitates cleaning and has higher thermal efficiency. In this way, the user can only see the external parts such as the pot support, panel or magnetic control knob, while the burner, liquid tray 7 and other components are completely blocked by the pot support assembly 9. Therefore, from the top view, only the external parts such as the pot support assembly 9, panel and magnetic control knob are visible, while the burner, liquid tray 7 and other components are completely blocked by the heat-conducting plate 93.

[0048] More preferably, the heat-conducting plate 93 can be fixed on the support frame 92 or detachably installed on the support frame 92. The upper end surface of the support frame 92 is lower than the upper surface of the heat-conducting plate 93. When the cookware is placed on the heat-conducting plate 93, the bottom wall of the cookware is in close contact with the top wall of the heat-conducting plate 93, thereby creating a gap between the cookware and the support frame 92.

[0049] In this embodiment, if the heat-conducting plate 93 is made of an infrared-transparent material, then the heat-conducting plate 93 will conduct heat to the bottom of the pot after being heated; if the heat-conducting plate 93 is infrared-transparent, then in addition to the heat conduction between the guide plate and the pot, the infrared light waves emitted by the infrared combustion plate can also penetrate the heat-conducting plate 93 to conduct radiative heat transfer to the pot.

[0050] Preferably, a first ventilation opening is provided on the bottom wall of the stove body 1, and a first and second air passage 23 is defined in the vertical direction at the middle position of the burner head 2, and the first and second air passage 23 is connected to the first ventilation opening.

[0051] Furthermore, a second ventilation opening is provided on the bottom wall of the stove body 1, a second secondary air channel 24 is defined between the support plate 5 and the burner head 2, the lower end of the second secondary air channel 24 is connected to the second ventilation opening, and a third secondary air channel 25 is defined between the liquid tray 7 and the burner head 2, the upper end of the third secondary air channel 25 is connected to the second secondary air channel 24.

[0052] Specifically, a flange 71 is provided on the upper edge of the liquid collection tray 7, which abuts against the panel of the stove body 1, and the bottom wall of the liquid collection tray 7 is connected to the top wall of the support plate 5 so that the liquid collection tray 7 is recessed into the stove body 1.

[0053] Specifically, a flange 72 is provided at the lower edge of the liquid-holding tray 7, which is bent upwards.

[0054] In this embodiment, a first and second air passage 23 is provided vertically in the middle position of the burner head 2. Since a first vent and a second vent are respectively opened on the bottom wall of the stove body 1, the first and second air passage 23 is connected to the first vent. The cold air with low temperature flows upward from the first and second air passage 23, and also carries away some of the heat in the internal space of the burner head 2. In addition, a second and second air passage 24 is defined between the support plate 5 and the burner head 2, and a third and second air passage 25 is defined between the liquid tray 7 and the burner head 2. The lower end of the second and second air passage 24 is connected to the second vent, and its upper end is connected to the upper end of the second and second air passage 24. The cold air with low temperature flows upward after passing through the second vent, the second and second air passage 24, and the third and second air passage 25 in sequence, thereby also carrying away some of the heat around the burner.

[0055] In this embodiment, the burner head 2 is recessed within the stove body 1. Simultaneously, the liquid collection tray 7 is preferably a recessed structure. Since the liquid collection tray 7 itself can also insulate against the heat radiated by the infrared burner 22, and the cold air flowing upwards from the two vents replenishes the combustion air while also carrying away some heat from the burner's periphery, further reducing the panel temperature. After flowing upwards from the secondary air channel, the cold air not only satisfies the overall combustion requirements but also carries away some heat, lowering the temperature of the liquid collection tray 7 and other components such as the panel.

[0056] Furthermore, the inner end of the recessed liquid-holding tray 7 has an upward-curving edge 72, which gives the tray 7 a certain liquid-holding capacity. Even if a small amount of liquid flows into the tray 7, it will not continue to flow to the bottom of the stove. When it is necessary to clean the dirt in the tray 7, simply remove the pot support from the stove body for cleaning. Of course, if... Figure 2 and 3 As shown, the top of the pot support protrudes from the panel very low, which allows the burner and pot support of the burner head 2 to sink into the burner head 2, making the whole machine flatter and thus more aesthetically pleasing.

[0057] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
