DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0047] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0048] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0049] The working principle of a gas stove is as follows: high-pressure gas (natural gas or liquefied gas) enters the valve body of the gas stove from the gas pipeline. After the valve body opens, it flows into the nozzle. Since the nozzle size is very small, generally less than 2mm, the high-pressure gas becomes high-speed, low-pressure gas after flowing out of the nozzle, and enters the Venturi structure of the burner to form a negative pressure (lower than atmospheric pressure). Therefore, primary air is induced to flow into the burner. After the primary air is mixed with the gas, it flows out through the burner into the gas distribution plate and fire cover for combustion. During the combustion process, the air in the environment will be supplemented for a second time, namely secondary air, to ensure complete combustion of the gas.

[0050] From the operating principle, it can be seen that the amount of primary and secondary air is the core key factor in ensuring complete combustion of gas. In existing gas stove combustion systems, gas is mixed with primary air before combustion, so it is considered that primary air is almost completely involved in the reaction. Secondary air participates in the reaction during the combustion process due to buoyancy and the entrainment of the high-speed gas jet, so the secondary air does not fully participate in the reaction. While ensuring complete reaction of the gas, the total amount of air should be minimized as much as possible to reduce the heat released by the combustion reaction and heat the excess air, thereby improving thermal efficiency.

[0051] At present, the replenishment of secondary air in gas stoves is generally achieved by optimizing the fire hole structure and increasing the contact area between the fire hole and the air. It is difficult to replenish secondary air effectively and quickly, especially when the smoke exhaust port is reduced. The replenishment of secondary air is even more difficult, which not only fails to achieve a better combustion state, but also causes the smoke to exceed the standard.

[0052] That is to say, the above-mentioned method of increasing the amount of secondary air added cannot yet ensure complete combustion of the fuel gas under the optimal state, and there is room for improvement.

[0053] Based on the above technical problems, an embodiment of the present application provides a gas stove, which aims to improve the amount of secondary air supplemented to at least a certain extent, so as to make the gas burn completely under the best condition as much as possible.

Figure 4 for Figure 1 A schematic diagram of the stove shell with the panel removed. Figures 1-4 The stove shell 100 of the embodiment of the present application includes a cover body 101, a sealed chamber 102 and a fan 103, wherein the burner 200 is assembled on the cover body 101, the sealed chamber 102 is arranged in the cover body 101, and the side wall of the sealed chamber 102 is provided with an air inlet 104, a first through hole 105 for the inlet end of the burner head of the burner 200 to pass through, and a second through hole 106 for the outlet end of the burner head of the burner 200 to pass through. The fan 103 is arranged in the sealed chamber 102, and the gas distribution plate 202 of the burner 200 covers the second through hole 106 of the sealed chamber 102. The gas distribution plate 202 is provided with a plurality of secondary air vents that connect the inside of the sealed chamber 102 with the outside.

[0057] When a gas stove provided by the present application is in use, the fan 103 is controlled to start, and the fan 103 introduces supplementary secondary air into the sealed chamber 102 through the air inlet 104. The secondary air introduced into the sealed chamber 102 is then supplemented into the burner 200 through the multiple secondary air vents on the air distribution plate 202, so as to improve the supplementary amount of secondary air, thereby allowing the gas to be completely burned in the best state, thereby improving the combustion efficiency of the gas stove.

Of course, other methods can also be used, and the embodiments of the present application are not limited to this.

[0062] In other embodiments, the vertical plates 107 of the embodiment of the present application may also be provided in an unenclosed manner. For example, two vertical plates 107 are provided in an opposite manner, with the two sides of the two vertical plates 107 respectively resting against two opposite side walls of the cover body 101. The two vertical plates 107, the two opposite side walls of the cover body 101, and the top and bottom of the cover body 101 may also enclose the aforementioned sealed chamber 102. The embodiment of the present application does not impose any specific limitation on the specific form of the sealed chamber.

[0064] Furthermore, the air inlet 104 of the embodiment of the present application is arranged on the vertical plate 107, and the fan 103 is installed on the air inlet 104. The output end of the fan 103 faces the interior of the sealed chamber 102. By controlling the start-up of the fan 103, the air outside the sealed chamber 102 can be introduced into the sealed chamber 102.

[0065] In addition, in the embodiment of the present application, a support block may be provided at the bottom of the cover body 101 . The support block is provided in the sealed chamber 102 , and the fan 103 is supported by the support block to improve the stability of the fan 103 installed in the cover body 101 .

[0066] It should be noted that the number of sealed chambers 102 and fans 103 in the embodiment of the present application can be set according to the specific number of burners 200. For example, two burners 200 are installed on the cover body 101 of the stove shell 100 in the embodiment of the present application. Accordingly, the embodiment of the present application also has two sealed chambers 102 and fans 103 corresponding to the burners 200 in the cover body 101.

The part of the gas distribution plate 202 located between the third ring sleeve 217 and the second ring sleeve 216 can be the third air induction plate 209 of the embodiment of the present application, that is, the third air induction plate 209 of the embodiment of the present application is annularly arranged between the third ring sleeve 217 and the second ring sleeve 216, and since the third air induction plate 209 is arranged below the fire holes of the inner ring fire cover 203 and the fire holes of the outer ring fire cover 204, the multiple third air induction holes 210 on the third air induction plate 209 can be annularly spaced, so that the secondary air introduced from the multiple third air induction holes 210 can evenly act on the root of the flame generated by the fire hole to further improve the combustion effect.

[0084] Combine Figure 8The fire outlet end of the fire hole of the outer ring fire cover 204 of the embodiment of the present application is set to face the inner ring of the outer ring fire cover 204, that is, the outer ring fire cover 204 of the embodiment of the present application is flame-built-in, and the central axes of the fire holes of the outer ring fire cover are all set in parallel, and the central axes of the fire holes of the outer ring fire cover 204 are all set at an angle.

[0085] Combine Figure 5-Figure 7 The burner 200 of the embodiment of the present application further includes a second air inlet plate 213 . Figure 10 for Figure 5 The structural diagram of the second air inlet plate in FIG. Figure 5-Figure 8 as well as Figure 10 The second air inlet plate 213 is disposed between the outer ring fire cover 204 and the inner ring fire cover 203. The second air inlet plate 213 is disposed above the third air guide plate 209. The second air inlet plate 213 is provided with a plurality of annular second air inlet holes 214. The central axes of the plurality of second air inlet holes 214 on the second air inlet plate 213 are all arranged in parallel. Furthermore, the central axes of the plurality of second air inlet holes 214 on the second air inlet plate 213 are all arranged at an angle, and the inclination direction of the central axis of the second air inlet hole 214 is opposite to the inclination direction of the central axis of the fire hole of the outer ring fire cover 204. In this way, the secondary air introduced from the plurality of second air inlet holes 214 on the second air inlet plate 213 can directly act on the fire outlet end of the fire hole of the outer ring fire cover 204, allowing the gas to be completely burned in an optimal state, thereby further improving the combustion efficiency and having great practical value.

[0086] Further, combined with Figure 10 In the embodiment of the present application, a plurality of second grooves can be provided at intervals on the outer circumference of the second air inlet plate 213. The plurality of second grooves and the inner ring of the outer ring fire cover 204 can form the plurality of second air inlet holes 214. Of course, the plurality of second air inlet holes 214 can also be provided directly through the end surface of the second air inlet plate 213, and this embodiment of the present application is not limited thereto.

[0087] In an embodiment of the present application, the second air inlet plate 213 can be arranged in a separate manner between the inner ring fire cover 203 and the outer ring fire cover 204. Specifically: a second positioning cavity in the shape of a cone is provided at the top of the area between the inner ring fire cover 203 and the outer ring fire cover 204. Accordingly, the outer peripheral surface of the second air inlet plate 213 has an outer shape that matches the second positioning cavity, and the second air inlet plate 213 can be detachably positioned and supported in the second positioning cavity between the inner ring fire cover 203 and the outer ring fire cover 204.

[0088] In other embodiments, the second air inlet plate 213 may also be directly fixed between the inner ring fire cover 203 and the outer ring fire cover 204 by integral molding or welding, and the embodiments of the present application do not impose specific limitations on this.

[0089] Combine Figure 5-Figure 7In an embodiment of the present application, a fourth ring sleeve 218 can be coaxially arranged in the middle of the top surface of the gas distribution plate 202, and the fourth ring sleeve 218 is arranged on the outside of the third ring sleeve 217. The area between the fourth ring sleeve 218 and the third ring sleeve 217 is the above-mentioned outer ring mixing chamber, and the outer ring fire cover 204 can be detachably arranged on the gas distribution plate 202 between the fourth ring sleeve 218 and the third ring sleeve 217. The outer ring fire cover 204 can be limited by the fourth ring sleeve 218 and the third ring sleeve 217.

[0090] In addition, when the outer ring fire cover 204 is assembled on the gas distribution plate 202, the outer ring fire cover 204, the inner ring fire cover 203 and the gas distribution plate 202 can form a ring structure with an open top. When the secondary air flows to the fire holes of the inner ring fire cover 203 and the outer ring fire cover 204, it can be protected from external interference and prevent turbulence.

[0091] Combine Figure 5-Figure 7 The burner 200 of the present embodiment further includes a fourth air induction plate 219, which is disposed within the outer ring mixing chamber of the gas distribution plate. The fourth air induction plate 219 covers the second connection port between the gas distribution plate 202 and the outer ring ejector pipe of the burner head 201. The fourth air induction plate 219 is provided with a plurality of fourth air induction holes 220. Thus, primary air can be introduced into the outer ring fire cover 204 through the fourth air induction plate 219.

[0092] Further, combined with Figure 7 In the embodiment of the present application, the fourth air induced draft plate 219 is in an arc shape consistent with the second connecting port. The fourth air induced draft plate 219 can be integrally formed with the gas distribution plate 202 or separately arranged. Moreover, the fourth air induced draft plate 219 is arranged below the fire hole of the outer ring fire cover 204. The multiple fourth air induced draft holes 220 on the fourth air induced draft plate 219 are arranged at intervals, so that the primary air introduced from the multiple fourth air induced draft holes 220 can evenly act on the root of the flame generated by the fire hole to further improve the combustion effect.

[0093] To sum up, the gas stove provided in the embodiment of the present application realizes the active supply of secondary air to the gas stove by ventilating the sealed cavity in the stove shell of the gas stove through the fan. At the same time, through the arrangement of the air induced plate and the air inlet plate, the air supplied by the fan in the stove shell can continue to supplement the gas combustion, which is a new secondary air supplement method.

[0094] In the prior art, for burners with additional energy-gathering discs, the smoke outlet is generally required to be higher than 8mm, otherwise it will result in insufficient secondary air supply and increased smoke. However, using the secondary air supply method of the embodiment of the present application, the smoke outlet can be reduced to approximately 5mm, still ensuring sufficient secondary air supply and complete combustion. In other words, the embodiment of the present application allows the gas stove to fully burn the gas through the fan even when secondary air supply is difficult, which has excellent practical value.
