Description

Technical Field

[0001] The present invention relates to the technical field of cookers, and in particular to an infrared gas cooker. Background Art

[0002] For a conventional gas cooker, the pot support is open, as shown in the attached drawings. During cooking, the overflowing liquid will flow down from the edge of the pot to the pot support, the liquid tray and the burner, which is not convenient for cleaning. Moreover, the burner and the pot support are relatively high, and the appearance is not good-looking.

[0003] The heat transfer mode of the infrared cooker is mainly thermal radiation. The combustion temperature on the upper surface of the combustion plate is nearly 1000 °C. Since thermal radiation is proportional to the fourth power of the temperature, when the combustion plate burns, it will radiate a relatively large amount of heat to the inside or outside of the burner head, resulting in a relatively high temperature rise of the burner head and also a relatively large amount of heat loss, thus restricting the improvement of the thermal efficiency of the infrared cooker. Summary of the Invention

[0031] Embodiment:

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

[0033] A stove body 1;

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

[0035] A flow guiding and heat insulating plate 3, the flow guiding and heat insulating plate 3 is arranged inside the premixing chamber 21. A plurality of through holes 31 for the mixed gas to pass through are opened on the flow guiding and heat insulating plate 3. The outer edge of the flow guiding and heat insulating plate 3 and the upper end wall of the premixing chamber 21 are cooperatively connected to jointly define a heat insulating chamber 211;

[0036] A first heat insulating member 4, the first heat insulating member 4 is arranged inside the heat insulating chamber 211;

[0037] The support plate 5 is arranged on the stove body 1, and the support plate 5 is located at an external position of the burner head 2;

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

[0039] The liquid receiving tray 7 is arranged on the support plate 5.

[0040] In this embodiment, the burner head 2 is arranged in the stove body 1. A premixing chamber 21 is defined in the burner head 2. An infrared combustion body 22 is covered at the upper end position of the premixing chamber 21. The flow guiding heat insulation plate 3 is arranged in the premixing chamber 21. A plurality of through holes 31 for the mixture gas to pass through are formed in the flow guiding heat insulation plate 3 so that the premixing chamber 21 communicates up and down. In this way, the flow guiding heat insulation plate 3 can block most of the heat radiated from the lower side of the infrared combustion body 22 to the burner head 2, thereby reducing the temperature rise inside the burner head 2 and the stove. Through the cooperation connection between the outer edge of the flow guiding heat insulation plate 3 and the upper end wall of the premixing chamber 21, a heat insulation chamber 211 is jointly defined. A first heat insulation member 4 is arranged in the heat insulation chamber 211. Through the cooperation action between the first heat insulation member 4 and the upper end wall of the premixing chamber 21, part of the heat transmitted downward or horizontally is further blocked, so that the temperature of the lower part of the entire burner assembly is greatly reduced. This is the internal heat insulation of the burner. A support plate 5 is arranged on the stove body 1, and the support plate 5 is located at an external position of the burner head 2. A second heat insulation member 6 is arranged on the inner side wall of the support plate 5. In this way, the heat radiated from the bottom of the burner to the surroundings can be effectively blocked. This is the external heat insulation of the burner. Thus, by arranging multiple heat insulation structures on the burner head 2, the temperature of the stove top and internal components can be kept within a safe value range. Its structure is simple, the heat loss of the infrared combustion body 22 can be reduced, and the thermal efficiency of the infrared burner can be improved.

[0041] Furthermore, a bottom heat insulation plate 8 is further included. An accommodation cavity is defined in the bottom heat insulation plate 8. The lower end of the burner head 2 is arranged in the accommodation cavity.

[0042] In this embodiment, the bottom heat insulation plate 8 has a bottom plate and side plates. The side plates are respectively arranged at the circumferential edge positions of the bottom plate. In this way, an accommodation cavity can be defined in the internal space of the bottom heat insulation plate 8, and then the lower end of the burner head 2 is recessed in the accommodation cavity, so that the heat radiated from the bottom of the burner of the burner head 2 to the surroundings can be effectively blocked.

[0043] Preferably, a pot support assembly 9 is further included. The pot support assembly 9 is arranged 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 conduction plate 93. The base 91 is disposed on the panel of the stove body 1, and the lower end of the base 91 is correspondingly arranged opposite to the liquid receiving tray 7. The support frame 92 is disposed on the base 91, and the heat conduction plate 93 is mounted on the base 91 through the support frame 92, so that a smoke exhaust port 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.

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

[0046] Furthermore, the projected area of the heat conduction plate 93 is larger than the projected area of the base 91, or the projected area of the heat conduction plate 93 is larger 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 head 2 is disposed at the opening position of the stove body 1. First, the liquid receiving tray 7 is sleeved on the outer edge of the opening of the stove body 1, and then the base 91 is continuously sleeved on the outer edge of the opening of the stove body 1, so that the upper end of the base 91 presses on the top wall of the liquid receiving tray 7, and the lower end of the base 91 is correspondingly arranged opposite to the liquid receiving tray 7. The support frame 92 is disposed on the base 91, and the heat conduction plate 93 is mounted on the base 91 through the support frame 92, so that a smoke exhaust port 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 the gas on the infrared combustion body 22 is discharged outward through the smoke exhaust port 94, thereby heating the cookware, that is, performing convective heat transfer on the cookware. In addition, the projected area of the heat conduction plate 93 is larger than the projected area of the base 91, or the projected area of the heat conduction plate 93 is larger than the projected area of the burner head 2, so as to effectively block the overflow liquid from flowing toward the pot support base 91 and the burner area, that is, the diameter of the heat conduction plate 93 is respectively larger than the diameter of the base 91 and the diameter of the opening of the burner head 2, so as to facilitate cleaning and have a higher thermal efficiency. In this way, the user can only see the appearance parts such as the pot support, the panel, or the magnetic control knob, and components such as the burner and the liquid receiving tray 7 are completely blocked by the pot support assembly 9. Then, from the top view, only the appearance parts such as the pot support assembly 9, the panel, and the magnetic control knob can be seen, and components such as the burner and the liquid receiving tray 7 are completely blocked by the heat conduction plate 93.

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

[0049] In this embodiment, if the heat conduction plate 93 is made of a material that is impervious to infrared light, then after the heat conduction plate 93 is heated, it conducts heat to the bottom of the pot; if the heat conduction plate 93 is permeable to infrared light, then in addition to the heat conduction between the diversion plate and the cooking utensil, the infrared light waves emitted by the infrared burner can also penetrate the heat conduction plate 93 to conduct radiant heat transfer to the cooking utensil.

[0050] Preferably, a first ventilation opening is formed in the bottom wall of the stove body 1, and a first secondary air passage 23 is defined in the middle position of the burner head 2 in the vertical direction, and the first secondary air passage 23 is communicated with the first ventilation opening.

[0051] Further, a second ventilation opening is formed in the bottom wall of the stove body 1, a second secondary air passage 24 is defined between the support plate 5 and the burner head 2, the lower end of the second secondary air passage 24 is communicated with the second ventilation opening, and a third secondary air passage 25 is defined between the liquid receiving tray 7 and the burner head 2, and the third secondary air passage 25 is communicated with the upper end of the second secondary air passage 24.

[0052] Specifically, a flange 71 protrudes outward from the upper edge of the liquid receiving tray 7, the flange 71 abuts against the panel of the stove body 1, and the bottom wall of the liquid receiving tray 7 is cooperatively connected with the top wall of the support plate 5 so that the liquid receiving tray 7 is recessed in the stove body 1.

[0053] Particularly, a flanging 72 is bent upward at the lower edge of the liquid receiving tray 7.

[0054] In this embodiment, a first secondary air passage 23 is provided in the middle position of the burner head 2 in the vertical direction. Since a first ventilation opening and a second ventilation opening are respectively formed in the bottom wall of the stove body 1, and the first secondary air passage 23 is communicated with the first ventilation opening, cold air with a low temperature flows upward from the first secondary air passage 23, and at the same time, part of the heat in the internal space of the burner head 2 is also carried away. In addition, a second secondary air passage 24 is defined between the support plate 5 and the burner head 2, and a third secondary air passage 25 is defined between the liquid receiving tray 7 and the burner head 2. The lower end of the second secondary air passage 24 is communicated with the second ventilation opening, and its upper end is communicated with the upper end of the second secondary air passage 24. Cold air with a low temperature flows upward after flowing through the second ventilation opening, the second secondary air passage 24, and the third secondary air passage 25 in sequence, thereby also carrying away part of the heat outside the periphery of the burner.

[0055] In this embodiment, the burner head 2 is sunk in the stove body 1. At the same time, the liquid receiving tray 7 is preferably of a concave structure. Since the liquid receiving tray 7 itself can also isolate the heat radiated by the infrared burner 22 to the surroundings, and at the same time, cold air flows upward from the two ventilation openings to supply air for combustion and can also take away part of the heat around the burner, thereby further reducing the temperature of the panel. After the cold air flows upward through the secondary air passage, in addition to meeting the total combustion requirements, it can also take away a certain amount of heat and reduce the temperatures of components such as the liquid receiving tray 7 and the panel.

[0056] In addition, the inner end of the concave liquid receiving tray 7 is provided with an upward flanging 72, which enables the liquid receiving tray 7 to have a certain liquid receiving volume, so that even if a small amount of liquid flows into the liquid receiving tray 7, it will not continue to flow towards the bottom of the stove. When it is necessary to clean the dirt in the liquid receiving tray 7, the pot support can be removed from the stove body for sanitary cleaning. Of course, as Figure 2 and 3 shown, the height of the top of the pot support protruding from the panel is very low, so that the burner of the burner head 2 and the pot support are sunk in the burner head 2, making the whole machine flatter and thus making its appearance more beautiful.

[0057] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
