Description

Technical Field

[0001] The present invention relates to the technical field of gas water heaters, and in particular to a stove with a load-raising function. Background Art

[0002] Current stir-fry technology primarily increases the heat load by momentarily increasing the gas flow rate in the inner or outer ring of the burner to meet stir-fry needs. However, increasing the heat load of a single ring can only increase the heat load to a limited extent. Significantly increasing the heat load of a single ring can easily focus the heat on a single ring, causing abnormal combustion conditions, yellow flames, and excessive CO levels in the exhaust gas, compromising product safety. Furthermore, a large heat load associated with the stir-fry function inevitably leads to a significant increase in the air demand for gas combustion. If the burner's combustion range and air content remain essentially unchanged, the added gas can lead to incomplete combustion, resulting in yellow flames or increased CO levels in the exhaust gas, potentially impacting user safety over time. If the heat load associated with the stir-fry function is relatively small, the stir-fry function will inevitably provide a suboptimal user experience, rendering it ineffective. Using solutions such as air blasting to address this issue increases costs and reduces product reliability because the air flow generated by the blasting cannot accurately match combustion requirements.

In addition, opening the stir-frying assembly 5 before ignition can quickly increase the amount of gas in the burner, achieving instant ignition and improving the user experience.

[0060] In a preferred embodiment of the present invention,

[0061] The control valve 41 includes an outer ring air outlet end and an inner ring air outlet end;

[0062] The gas pipe assembly includes an outer ring gas pipe 401 and an inner ring gas pipe 402, wherein the outer ring gas pipe 401 is connected to the outer ring gas outlet end, and the inner ring gas pipe 402 is connected to the inner ring gas outlet end;

[0063] The burner 3 includes an outer ring ejector tube 301 and an inner ring ejector tube 302, and an outer ring mixing chamber 31 and an inner ring mixing chamber 32 are defined in the burner 3. The outer ring mixing chamber 31 is connected to the outer ring ejector tube 301, and the inner ring mixing chamber 32 is connected to the inner ring ejector tube 302. The outer ring ejector tube 301 is connected to the outer ring gas transmission tube 401, and the inner ring ejector tube 302 is connected to the inner ring gas transmission tube 402.

[0064] The stir-frying component 5 includes a stir-frying gas pipe 51 and a switch component 52, wherein one side of the stir-frying gas pipe 51 is connected to the gas pipe 2, and the other side is connected to the burner 3 to transport the gas in the gas pipe 2 to the burner 3. The switch component 52 is set on the stir-frying gas pipe 51 or the gas pipe 2, and is used to open or close the stir-frying gas pipe 51.

[0065] The mixing nozzle 53 has an input end connected to the gas pipe 2 and an output end connected to the stir-frying gas pipe 51 . A nozzle side hole 531 is also provided on the side wall of the mixing nozzle 53 for replenishing air to the stir-frying gas pipe 51 .

[0066] like Figure 1-4 As shown, the switch assembly 52 in this embodiment is a solenoid valve, which is arranged on the stir-fry gas pipe 51 or the gas pipe 2 and can open or close the stir-fry gas pipe 51. The outer ring mixing chamber 31 is connected to the outer ring ejector pipe 301, which is connected to the outer ring gas pipe 401, which is connected to the outer ring gas outlet end of the control valve 41; the inner ring mixing chamber 32 is connected to the inner ring ejector pipe 302, which is connected to the inner ring gas pipe 402, which is connected to the inner ring gas outlet end of the control valve 41. In this way, the gas in the gas pipe 2 can be transported to the outer ring mixing chamber 31 and the inner ring mixing chamber 32 of the burner respectively through the control valve 41; when the switch assembly 52 is turned on, the stir-fry gas pipe 51 is the stir-frying gas supply to the burner 3, and the gas in the stir-fry gas pipe 51 is a certain mixed ratio of air and gas. In this embodiment, the certain ratio of air and gas is simply referred to as mixed gas.

[0067] Specifically, a mixing nozzle 53 is added to the stir-fry gas pipe 51 and the gas pipe 2. The outer periphery of the mixing nozzle 53 is provided with multiple nozzle side holes 531 for replenishing air to the stir-fry gas pipe 51. By controlling the ratio of the air intake volume and the gas volume output by the mixing nozzle 53, secondary air replenishment can be avoided. At the same time, the air and gas entering the stir-fry gas pipe 51 can be premixed in the stir-fry gas pipe 51, providing a specific flow of mixed gas for stir-frying, thereby increasing the stir-frying load of the inner ring of the burner. Because the stir-frying gas circuit has primary air replenishment, its combustion requires less secondary air, which can quickly increase the stir-frying firepower of the inner ring and / or outer ring of the burner, and can burn fully without the need for blast pressure. The structure is simple and the design is reasonable. In addition, the switch component 52 can be controlled to open or close the stir-frying gas circuit by an independent stir-frying controller. The stir-frying controller can be touch-sensitive, temperature-feedback, etc. Since it is a prior art, the present invention will not be described in detail here.

[0068] In a preferred embodiment of the present invention, the structure of the nozzle side hole 531 is a cylindrical through hole, a conical hole or a Venturi hole, and the ratio of the air intake of the nozzle side hole 531 to the air output of the mixing nozzle 53 is 0.35~0.48.

[0069] like Figure 5 As shown, there are multiple nozzle side holes 531, which are evenly distributed along the periphery of the mixing nozzle 53. The structure of the nozzle side holes 531 is one of a cylindrical through hole, a conical hole or a Venturi hole, preferably a conical hole or a Venturi hole. This structure enables air to quickly and smoothly enter the output end of the mixing nozzle 53 and complete mixing with the gas.

[0070] In addition, for different types of gas, the ratio of the air intake of the nozzle side hole 531 to the air outlet of the mixing nozzle 53 is different. When the gas is natural gas, the ratio of the air intake of the nozzle side hole 531 to the air outlet of the mixing nozzle 53 is preferably 0.45~0.48; when the gas is liquefied gas, the ratio of the air intake of the nozzle side hole 531 to the air outlet of the mixing nozzle 53 is preferably 0.35~0.38; the disposable air supplemented through the nozzle side hole 531 makes the ratio of air and gas entering the stir-frying gas pipe 51 meet the stir-frying requirements, and at the same time can avoid the addition of additional gas, avoid the occurrence of yellow flames during product combustion, or increase the CO content in the exhaust gas, so that the burner 3 burns more fully, and there is no need to use measures such as blast pressurization to achieve full combustion of the product, thereby improving the safety of the product and simplifying the structure of the product.

[0071] In a preferred embodiment of the present invention, the stir-frying component 5 includes:

[0072] The nozzle holder 54 is provided between the burner 3 and the gas pipe assembly, and includes a nozzle holder body, wherein the nozzle holder body is provided with an air inlet 541, which is connected to the stir-fry gas pipe 51 for supplying gas to the air inlet 541;

[0073] The outer ring nozzle 55 has one end connected to the outer ring gas pipe 401 and the other end passing through the nozzle holder body and connected to the outer ring ejector pipe 301 to eject the gas in the outer ring gas pipe 401 into the outer ring ejector pipe 301;

[0074] The inner ring nozzle 56 has one end connected to the inner ring gas pipe 402 and the other end passing through the nozzle holder body and connected to the inner ring ejector pipe 302 to eject the gas in the inner ring gas pipe 402 into the inner ring ejector pipe 302;

[0075] The air exchange valve is provided at the air inlet 541 and is used to control the gas flow direction of the air inlet 541. The air exchange valve includes an air inlet, a first air outlet, and a second air outlet. The air inlet is connected to the air inlet 541.

[0076] Among them, the outer ring nozzle 55 is provided with an outer ring nozzle through hole, the inner ring nozzle 56 is provided with an inner ring nozzle through hole, and the outer ring air path channel 501 and the inner ring air path channel 502 are provided inside the nozzle seat body. The outer ring air path channel 501 is connected to the air inlet hole 541 and the outer ring nozzle through hole, and the inner ring air path channel 502 is connected to the air inlet hole 541 and the inner ring nozzle through hole. The first air outlet is connected to the outer ring air path to transport the gas in the stir-frying gas pipe 51 to the outer ring nozzle 55, and the second air outlet is connected to the inner ring air path to transport the gas in the stir-frying gas pipe 51 to the inner ring nozzle 56.

[0077] like Figure 6-8 As shown, this embodiment sets a nozzle seat 54 between the burner 3 and the gas pipe assembly, and installs the outer ring nozzle 55 and the inner ring nozzle 56 on the nozzle seat body. One end of the outer ring nozzle 55 is connected to the outer ring gas pipe 401, and the other end passes through the nozzle seat body and is connected to the outer ring ejector pipe 301. One end of the inner ring nozzle 56 is connected to the inner ring gas pipe 402, and the other end passes through the nozzle seat body and is connected to the inner ring ejector pipe 302. When the control valve 41 is opened, the gas in the gas pipe 2 can enter the outer ring nozzle 55 and the inner ring nozzle 56 from the inner ring gas pipe 402 and then enter the outer ring mixing chamber 31 and the inner ring mixing chamber 32 of the burner 3.

[0078] In addition, the outer ring nozzle 55 is provided with an outer ring nozzle through hole, the inner ring nozzle 56 is provided with an inner ring nozzle through hole air inlet 541, and the nozzle seat body is provided with an outer ring air path channel 501 and an inner ring air path channel 502. The outer ring air path channel 501 is connected to the air inlet 541 and the outer ring nozzle through hole, and the inner ring air path channel 502 is connected to the air inlet 541 and the inner ring nozzle through hole. By setting a gas exchange valve at the output end of the air inlet 541, the gas exchange valve is a two-position three-way valve. Since the first outlet is connected to the In the outer ring gas path, the second gas outlet is connected to the inner ring gas path, and the air exchange valve can control the opening and closing of the first gas outlet and the second gas outlet, so that the mixed gas in the stir-frying gas pipeline 51 can be transported to the outer ring gas path channel 501 to realize the outer ring stir-frying, and can also be input into the inner ring gas path channel 502 to realize the inner ring stir-frying, and can also be input into the outer ring gas path channel 501 and the inner ring gas path channel 502 at the same time, so that the outer and inner rings can be stir-fried at the same time, meeting the different stir-frying needs of users and enriching the functions of the stove. In addition, while the mixed gas in the stir-frying gas pipeline 51 provides the outer ring gas path channel 501 and the inner ring gas path channel 502 with a gas and air mixture, it can instantly increase the negative pressure in the outer ring ejector pipe 301 and the inner ring ejector pipe 302, thereby increasing the corresponding air intake amount, and thereby increasing the primary air coefficient during stir-frying.

[0079] In a preferred embodiment of the present invention, the stir-fry component 5 further comprises:

[0080] The stir-fry nozzle 57 is mounted on the nozzle holder body, wherein one end of the stir-fry nozzle 57 is connected to the air inlet 541;

[0081] The burner 3 is also provided with a stir-frying mixing chamber 33 and a connecting pipe 34, wherein the stir-frying mixing chamber 33 is located on the inner side of the inner ring mixing chamber 32, one end of the connecting pipe 34 is connected to the stir-frying mixing chamber 33, and the other end passes through the inner ring mixing chamber 32 and the outer ring mixing chamber 31 and is connected to the other end of the stir-frying nozzle 57 to transport the gas in the stir-frying gas pipe 51 to the stir-frying mixing chamber 33.

[0082] A stir-frying air passage 503 is also provided inside the nozzle holder body for connecting the air inlet 541 and the other end of the stir-frying nozzle 57 .

[0083] The air exchange valve further includes a third air outlet, which is connected to the stir-frying air passage 503 and is used to open or close the stir-frying air passage 503 .

[0084] like Figure 3-8As shown, the stir-fry mixing chamber 33 and the outer ring mixing chamber 31 and the inner ring mixing chamber 32 all supply air independently of each other, without changing the original gas channels of the outer ring mixing chamber 31 and the inner ring mixing chamber 32; there is an independent air supply channel between the stir-fry mixing chamber 33 and the gas pipe 2, and at the same time, a mixing nozzle 53 is installed at the front end of the stir-fry gas pipe 51, and the nozzle side hole 531 on the mixing nozzle 53 can replenish air once, and the air and gas are premixed in the stir-fry gas pipe 51 to form a mixed gas of air and gas in a certain proportion, thereby providing a mixed gas of a specific flow rate for stir-frying. The present invention can control the stir-frying gas pipe 51 to provide mixed gas to the stir-frying mixing chamber 33 through an independent switch component 52, thereby increasing the stir-frying load of the inner ring of the burner 3. When the stir-frying mixing chamber 33 is opened, it is only necessary to open the third air outlet of the air exchange valve, and the mixed gas in the stir-frying gas pipe 51 can enter the stir-frying gas path 503, and then enter the stir-frying nozzle 57, and finally enter the stir-frying mixing chamber 33 from the stir-frying nozzle 57, thereby realizing combustion in the outer ring mixing chamber 31, the inner ring mixing chamber 32 and the stir-frying mixing chamber 33, wherein the outer ring mixing chamber 31 and the inner ring mixing chamber 32 are in normal mode.

[0085] In addition, not only can you open only the third air outlet, you can also open only one of the first, second and third air outlets, or open two of the first, second and third air outlets, or even open the first, second and third air outlets at the same time to achieve maximum stir-frying firepower. In this way, different stir-frying firepower and stir-frying positions can be achieved according to the number of opened air outlets, and stir-frying can be divided into levels to meet the different stir-frying needs of users.

[0087] like Figure 8 As shown, the outer ring gas channel 501, the inner ring gas channel 502 and the stir-frying gas channel 503 are all gas channels with Tesla valve structures, which can accelerate the mixed gas provided by the stir-frying gas pipe 51, so that the mixed gas quickly enters the burner 3, thereby quickly increasing the combustion load.

[0088] In a preferred embodiment of the present invention, the outer ring air path channel 501, the inner ring air path channel 502 and the stir-frying air path channel 503 are all equipped with one-way valves, so that the mixed gas in the air inlet 541 can enter the outer ring nozzle 55, the inner ring nozzle 56 and the stir-frying nozzle 57 from the outer ring air path channel 501, the inner ring air path channel 502 and the stir-frying air path channel 503 respectively; at the same time, it can avoid that, in the non-stir-frying state, the gas in the outer ring nozzle 55 and the inner ring nozzle 56 enters the corresponding outer ring air path channel 501 and the inner ring air path channel 502 respectively, which may cause insufficient gas during ignition, slow ignition, and reduce the user experience.

[0089] In a preferred embodiment of the present invention, the burner 3 is further provided with a stir-frying mixing chamber 33 and a connecting pipe 34. The stir-frying mixing chamber 33 is located on the inner side of the inner ring mixing chamber 32. One end of the connecting pipe 34 is connected to the stir-frying mixing chamber 33, and the other end passes through the inner ring mixing chamber 32 and the outer ring mixing chamber 31 and is connected to the stir-frying gas pipe 51.

[0090] like Figure 3-4 As shown, the stir-fry mixing chamber 33 and the outer ring mixing chamber 31 and the inner ring mixing chamber 32 all supply air independently of each other, without changing the original gas channels of the outer ring mixing chamber 31 and the inner ring mixing chamber 32; there is an independent air supply channel between the stir-fry mixing chamber 33 and the gas pipe 2, namely the stir-fry gas pipe 51, and at the same time, a mixing nozzle 53 is installed at the front end of the stir-fry gas pipe 51, and the nozzle side hole 531 on the mixing nozzle 53 can replenish air once, and the air and gas are premixed in the stir-fry gas pipe 51 to form a mixed gas of air and gas in a certain proportion, thereby providing a mixed gas of a specific flow rate for stir-frying. The present invention can control the stir-frying gas pipe 51 through an independent switch component 52 to provide mixed gas to the stir-frying mixing chamber 33, thereby increasing the stir-frying load of the inner ring of the burner 3; of course, the stir-frying mixing chamber 33 can also be set between the outer ring mixing chamber 31 and the inner ring mixing chamber 32, but if this structure is adopted, in the non-stir-frying state, since the stir-frying mixing chamber 33 does not burn, it will cause a gap between the outer ring fire and the inner ring fire, making the bottom of the pot heated unevenly; and by adopting the solution of this embodiment, the stir-frying mixing chamber 33 is set on the inner side of the inner ring mixing chamber 32, which can avoid insufficient firepower for stir-frying with the inner fire, and the design is more reasonable. In addition, the stir-frying mixing chamber 33 has a one-time air supplement, and even in the case of additional gas, it will not cause incomplete combustion of the product, yellow flames when the product burns, or increased CO content in the exhaust gas.
