Description

Technical Field

[0001] The present invention relates to the technical field of household kitchen appliances, and in particular to an integrated stove with stable combustion. Background Art

[0002] The existing integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, electromagnetic cooker, steamer, oven, disinfection cabinet, etc. It has the advantages of saving space, good smoke exhaust effect, energy saving, low consumption and environmental protection. However, the embedded modules of the integrated stove in the existing technology, such as the heat dissipation exhaust fan, burner, etc., are inconvenient to disassemble and assemble. For this reason, a Chinese utility model with patent number ZL202021361258.1 (authorization announcement number CN212657759U) "An integrated stove structure with a burner" includes an integrated stove frame and a Two burner bodies are spaced apart, and a heat dissipation exhaust fan and an intelligent steamer are also installed in the integrated stove frame. The burner body is detachably connected to the integrated stove frame, and the heat dissipation exhaust fan is detachably connected to the integrated stove frame. The heat dissipation exhaust fan includes a fan body and a volute body. The volute body is provided with a main air outlet. The volute body is provided with a flat plate section, so that the air passing through the volute body is interrupted and dispersed by the flat plate section, reducing the continuous flow of airflow and overcoming the problem that traditional fans all have arc or spiral airflow and continuous airflow causing high noise. When the temperature inside the integrated stove is high, although the heat dissipation exhaust fan can play a certain role in heat dissipation, it is also easy to form a negative pressure in the integrated stove. If the burner is selected as a bottom-inlet burner, the negative pressure makes it easier for external air to be sucked in for heat dissipation. As a result, the stove burner ejector cannot properly eject the air required for combustion, thereby causing the stove to malfunction.

[0003] In addition, if the burner is selected as a down-air burner, the burner generally includes a burner head, a base, an inner ring fire cover and an outer ring fire cover. The upper part of the burner head is provided with an inner ring gas outlet and an outer ring gas outlet. The base is provided with an inner ring channel, an outer ring channel, and inner and outer ring secondary air supply channels from the inside to the outside. The base is installed on the upper part of the burner head. The inner ring channel and the outer ring channel on the base are respectively connected to the inner ring gas outlet and the outer ring gas outlet on the burner head. The inner ring fire cover and the outer ring fire cover are respectively covered on the upper part of the inner ring channel and the outer ring channel of the base. For example, the Chinese utility model "A burner for a gas stove" with patent number ZL201921355862.0 (authorization announcement number CN210861199U) applied for by the present applicant has a mesh fire cover with an inner ring fire cover and a gas channel running through the center of the base. Since the gas channel is directly connected to the inner ring fire cover, the mesh fire cover ignites too quickly, which easily causes the center of the bottom of the pot to turn black. Further improvements are needed for this purpose. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated stove that can effectively dissipate heat while not affecting the introduction of primary air by the ejector pipe in response to the above-mentioned existing technical status.

[0005] The second technical problem to be solved by the present invention is to provide an integrated stove that can effectively dissipate heat while introducing preheated primary air into the ejector tube in response to the above-mentioned existing technical status.

[0006] The third technical problem to be solved by the present invention is to provide an integrated stove, in view of the above-mentioned existing technical status, which can not only meet the requirement of sufficient primary air replenishment but also prevent the burner from igniting too quickly, especially for a mesh-type fire cover.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: the integrated stove includes an integrated stove body, and an opening is provided on the integrated stove body for external cold air to flow in, and is characterized in that: a fan is arranged in the integrated stove body, and the fan has a fan inlet and a fan outlet, the fan inlet is used to inhale the hot air formed after the external cold air passes through the interior of the integrated stove body, and is also connected to an air supply duct at the fan outlet for sending out the air flowing out of the fan outlet, the air supply duct includes a first air supply outlet and a second air supply outlet, the first air supply outlet is connected to the air inlet end of the injection pipe for injecting gas and primary air, and the second air supply outlet is connected to the environment outside the integrated stove body.

[0008] To address the second technical problem, preferably, along the air flow direction of the air supply duct, the air supply duct is divided into a straight portion and a diffuser portion based on changes in cross-section, the first air supply outlet being located in the straight portion, and the second air supply outlet being located in the diffuser portion. The second air supply outlet being located in the diffuser portion, which is the portion with a gradually increasing cross-sectional area, can reduce the speed at which hot air flows to the external environment, while the first air supply outlet being located in the straight portion upstream of the diffuser portion can prevent heat loss from the hot air. This allows the hot air to be injected into the air inlet end of the ejector tube to a maximum extent before flowing to the external environment, thereby improving energy efficiency.

[0009] In order to better deliver the hot air to the air inlet end of the ejector tube, preferably, the first air outlet is connected to a first air supply pipe, and the first air supply pipe guides the air of the straight portion upward and horizontally.

[0010] Furthermore, the first air supply pipe has a vertical portion perpendicular to the straight portion and a transverse portion parallel to the straight portion, and an opening of the transverse portion is connected to the air inlet end of the ejector pipe.

[0011] In order to deliver hot air to the environment outside the integrated stove body, preferably, the integrated stove body is provided with a flow opening corresponding to the second air supply outlet, which is connected to the environment outside the integrated stove body.

[0012] To solve the third technical problem, preferably, the fan is arranged in the center of the integrated stove body, and burners are respectively arranged on both sides of the fan, each of the burners includes

[0013] The base includes a bottom wall and a convex wall extending upward from a periphery of the bottom wall, wherein the convex wall and the bottom wall form a concave cavity;

[0014] a connecting plate covering the concave cavity, the connecting plate further circumferentially defining at least two communicating holes communicating with the concave cavity, the circumference of the communicating holes being upwardly extended by an extending wall;

[0015] The outer ring gas mixing chamber comprises an inner ring wall surface and an outer ring wall surface that are annular and concentrically spaced and a bottom wall portion connecting the inner ring wall surface and the outer ring wall surface, the inner ring wall surface and the outer ring wall surface are covered with an outer ring fire cover, and the bottom wall portion is provided with a through hole that communicates with the communication hole;

[0016] Also includes

[0017] An inner gas channel, which is independently provided in the concave cavity of the base compared to the outer ring gas mixing chamber. Correspondingly, a connection portion for connecting the inner gas channel is provided on the base;

[0018] A mesh-type fire cover is provided on the inner gas channel;

[0019] an air guide channel, provided on the connecting portion and connecting the outer annular gas mixing chamber and the inner gas channel; and

[0020] The ejector tube is connected to the concave cavity of the base, and the air inlet end of the ejector tube is connected to the first air supply outlet.

[0021] By designing an air guide channel, the mixture of gas and primary air in the outer ring mixing chamber will be diverted to the inner gas channel, thereby avoiding the problem of excessive and rapid fire caused by the separate setting of the inner gas channel. In this way, the mesh fire cover located in the center can effectively avoid the current situation of excessive fire and easy burning of the bottom of the pot, and the air inlet end of the ejector pipe is connected to the first air supply outlet of the air supply duct, which can provide hot primary air for the burner, facilitating improving the combustion efficiency of the burner.

[0022] Furthermore, the connecting portion is an annular portion, and the internal gas channel is connected inside the annular portion.

[0023] To ensure more uniform heating of the pot bottom, a central ring fire cover is preferably provided between the outer ring fire cover and the mesh fire cover. The central ring fire cover is integrally provided with the mesh fire cover, and the gap between the annular portion and the inner gas channel forms a central gas channel connected to the central ring fire cover. The mesh fire cover and central ring fire cover are integrally provided, facilitating processing while allowing the burner to simultaneously provide both central and outer ring fires, plus the central mesh fire cover, for more uniform heating of the pot bottom.

[0024] In order to achieve the connection between the gas passages of the mesh type fire cover and the middle ring fire cover, preferably, a central connecting pipe for connecting the mesh type fire cover is provided in the center of the connecting plate, and the lower end of the central connecting pipe abuts against the inner gas channel, and an outer ring wall is also provided at the center of the connecting plate at intervals from the periphery of the central connecting pipe, and a connecting channel connected to the middle gas channel is formed between the outer ring wall and the outer wall of the central connecting pipe.

[0025] Since the mesh-type fire cover is integrally provided with the center ring fire cover, preferably, the center ring fire cover includes an annular wall and a top wall covering the annular wall, a central hole is provided in the center of the top wall for communication with the central connecting pipe, the hole wall of the central hole extends downward to form a connecting pipe connected to the central connecting pipe, and the mesh-type fire cover covers the central hole. By providing the central hole in the top wall of the center ring fire cover and using the connecting pipe extending from the central hole, communication with the central connecting pipe of the connecting plate and the internal gas channel is ultimately achieved, thereby enabling the mesh-type fire cover to smoothly emit fire.

[0026] To prevent spillage from affecting the mesh fire cover or the center ring fire cover, the top wall is preferably recessed downwardly from the periphery of the mesh fire cover to form a concave ring for collecting spillage. Spillage generated during cooking can flow into the concave ring, thereby reducing the amount of spillage flowing inward toward the mesh fire cover and outward toward the center fire hole of the center ring fire cover.

[0027] In order to realize the fire output of the outer ring fire cover and the inner ring fire cover, it is preferably in an annular form, the outer ring fire cover is provided with at least two outer fire holes spaced apart along the circumference, and the middle ring fire cover is provided with at least two middle fire holes spaced apart along the circumference.

[0028] In order to independently control the outer ring fire and the middle ring fire, preferably, the concave cavity of the base is connected to an outer ejector pipe, and the middle gas channel is connected to an inner ejector pipe.

[0029] Compared with the prior art, the advantages of the present invention are: by adding a fan to the integrated stove body, external cold air flows into the integrated stove body through the opening, and the hot air formed by the cold air passing through the components inside the integrated stove body can be sucked into the fan inlet and finally flows to the air supply duct. On the one hand, the hot air flowing out through the second air supply outlet can reduce the temperature inside the integrated stove body and ensure the heat dissipation effect of the integrated stove. On the other hand, the hot air flowing out through the first air supply outlet can be supplied to the air inlet end of the ejector tube, which is equivalent to providing preheated primary air to the ejector tube, which can improve the combustion efficiency of the burner in the integrated stove.

[0041] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0042] like Figures 1 to 11The figure shows the best embodiment of the present invention. In this embodiment, the integrated stove includes an integrated stove body 200, which is provided with an opening 201 for external cold air to flow in. The integrated stove body 200 is provided with a fan 300, which has a fan inlet 301 and a fan outlet 302. The fan inlet 301 is used to inhale the hot air formed after the external cold air passes through the interior of the integrated stove body 200, and is also connected to the fan outlet 302 with an air supply duct 400 for sending out the air flowing out of the fan outlet 302. The air supply duct 400 includes a first air supply outlet 401 and a second air supply outlet 402. The first air supply outlet 401 is connected to the air inlet end of the ejection pipe for ejecting gas and primary air, and the second air supply outlet 402 is connected to the environment outside the integrated stove body 200. Correspondingly, the integrated stove body 200 is provided with a flow port 202 corresponding to the second air supply outlet 402, which is connected to the environment outside the integrated stove body 200. Figure 2 The dotted arrows show the flow path of the hot air.

[0043] Along the air flow direction of the air supply duct 400, the air supply duct 400 is divided into a straight portion 403 and a diffuser portion 404 according to the change in cross-section. The first air supply outlet 401 is located in the straight portion 403, while the second air supply outlet 402 is located in the diffuser portion 404. The second air supply outlet 402 is located in the diffuser portion 404, which is the portion with a gradually increasing cross-sectional area, and can reduce the speed at which hot air flows to the external environment. The first air supply outlet 401 is located in the straight portion 403 upstream of the diffuser portion 404 to prevent heat loss in the hot air. This ensures that the hot air is injected into the air inlet end of the ejector pipe as much as possible before it flows to the external environment, thereby improving energy efficiency. In addition, in order to better deliver the hot air to the air inlet end of the ejector tube, the first air outlet 401 is connected to the first air supply pipe 405, and the first air supply pipe 405 guides the air in the straight portion 403 upward and horizontally. Specifically, the first air supply pipe 405 has a vertical portion 406 perpendicular to the straight portion 403 and a horizontal portion 407 parallel to the straight portion 403. The opening 201 of the horizontal portion 407 is connected to the air inlet end of the ejector tube, and finally the hot air is delivered to the air inlet end of the ejector tube in the burner.

[0044] Among them Figures 4-11As shown, the burner of this embodiment includes a base 1, including a bottom wall 11 and a convex wall 12 extending upward from the periphery of the bottom wall 11, wherein the convex wall 12 and the bottom wall 11 form a concave cavity 13, and the concave cavity 13 is covered with a connecting plate 2, and the connecting plate 2 is also provided with at least two connecting holes 21 connected to the concave cavity 13 along the circumferential direction, and the periphery of the connecting hole 21 extends upward with an extending wall 22. In order to facilitate the formation of an outer ring fire, it also includes an outer ring mixing chamber 3, which includes an inner ring wall surface 31 and an outer ring wall surface 32 that are annular and concentrically spaced, and a bottom wall portion 33 connecting the inner ring wall surface 31 and the outer ring wall surface 32. The inner ring wall surface 31 and the outer ring wall surface 32 are covered with an outer ring fire cover 4, and a through hole 34 connected to the connecting hole 21 is provided on the bottom wall portion 33. In order to facilitate the formation of a center fire, this burner also has an inner gas channel 5 and a mesh fire cover 6, wherein the inner gas channel 5 is also independently arranged in the concave cavity 13 of the base 1 compared to the outer ring mixing chamber 3. Correspondingly, a connecting portion 10 for connecting the inner gas channel 5 is provided on the base 1, and an air guide channel 7 is opened on the connecting portion 10. The air guide channel 7 connects the outer ring mixing chamber 3 and the inner gas channel 5. By designing the air guide channel 7, the mixed gas composed of the gas and primary air in the outer ring mixing chamber 3 is diverted to the inner gas channel 5, thereby avoiding the problem of excessive and rapid fire caused by the separate arrangement of the inner gas channel 5. In this way, the mesh fire cover 6 located in the center can effectively avoid the current situation of excessive fire and easy burning of the bottom of the pot. In addition, the concave cavity of the base is connected with an ejector pipe, and the air inlet end of the ejector pipe is connected with the first air supply outlet, which can provide hot primary air for the burner, helping to improve the combustion efficiency of the burner.

[0045] Specifically, the connecting portion 10 of this embodiment is an annular portion, and the inner gas channel 5 is connected within the annular portion. To ensure that the burner heats the pot bottom more evenly, a middle ring fire cover 8 is disposed between the outer ring fire cover 4 and the mesh fire cover 6. The middle ring fire cover 8 is integrally formed with the mesh fire cover 6, and the gap between the annular portion and the inner gas channel 5 forms a middle gas channel 9 connected to the middle ring fire cover 8. The mesh fire cover 6 and the middle ring fire cover 8 are integrally formed, facilitating processing while also enabling the burner to have both middle and outer ring fires, plus the centrally located mesh fire cover 6, for more even heating of the pot bottom. In addition, in order to achieve communication between the gas passages of the mesh fire cover 6 and the middle ring fire cover 8, a central connecting pipe 23 for connecting the mesh fire cover 6 is provided in the center of the connecting plate 2. The lower end of the central connecting pipe 23 abuts against the inner gas passage 5. An outer annular wall 24 is also provided in the center of the connecting plate 2 at intervals from the periphery of the central connecting pipe 23. A connecting passage 25 communicating with the middle gas passage 9 is formed between the outer annular wall 24 and the outer wall of the central connecting pipe 23. Moreover, since the mesh fire cover 6 and the middle ring fire cover 8 are integrally provided, the middle ring fire cover 8 includes an annular wall 81 and a top wall 82 covering the annular wall 81. A central hole 83 communicating with the central connecting pipe 23 is provided in the center of the top wall 82. The hole wall of the central hole 83 extends downward to form a connecting pipe 84 connected to the central connecting pipe 23. The mesh fire cover 6 covers the central hole 83. By opening a central hole 83 in the top wall 82 of the middle ring fire cover 8, and using the connecting pipe 84 extending from the central hole 83, communication with the central connecting pipe 23 of the connecting plate 2 and the internal gas channel 5 is finally achieved, so that the mesh fire cover 6 can fire smoothly.

[0046] Furthermore, in order to prevent the overflow from affecting the mesh fire cover 6 or the middle ring fire cover 8, the top wall 82 is further recessed on the periphery of the mesh fire cover 6 to form a concave ring 85 for containing the overflow. The overflow generated during the cooking process can flow into the concave ring 85. Internally, the overflow can reduce the flow toward the mesh fire cover 6, and externally, the overflow can reduce the flow toward the middle fire hole 80 of the middle ring fire cover 8. Finally, in order to achieve the fire output of the outer ring fire cover 4 and the inner ring fire cover, it is preferably in an annular form. The outer ring fire cover 4 is provided with at least two outer fire holes 40 spaced apart along the circumference, and the middle ring fire cover 8 is provided with at least two middle fire holes 80 spaced apart along the circumference. And in order to independently control the outer ring fire and the middle ring fire, the concave cavity 13 of the base 1 is connected to an outer ejector pipe 90, and the middle gas channel 9 is connected to an inner ejector pipe 100.

[0047] In summary, the mixed gas composed of the gas and the primary air ejected by the outer ejector tube 90 passes through the concave cavity 13 of the base 1 through the connecting hole 21 of the connecting plate 2 to the extension wall 22, and then enters the outer ring mixing chamber 3 through the through hole 34 opened in the bottom wall 11 of the outer ring mixing chamber 3, and finally flows out from the outer ring fire cover 4 and burns with the external secondary air to form an outer ring fire; the mixed gas composed of the gas and the primary air ejected by the inner ejector tube 100 passes through the connecting channel 25 to the middle gas channel 9 and then flows to the middle ring fire cover 8, and flows out from the middle ring fire cover 8 and burns with the external secondary air to form a middle ring fire; the mixed gas composed of the gas and the primary air in the outer ring mixing chamber 3 is diverted to the inner gas channel 5 through the air guide channel 7, and then to the central connecting pipe 23 on the connecting plate 2 and finally to the hole 83 of the central hole. The wall extends downward to form a connecting tube 84 connected to the central connecting tube 23, so as to constitute an air supply channel for the mesh-type fire cover 6, and finally form a fire outlet shape located in the center. The primary air of this embodiment is hot air. By adding a fan to the integrated stove body, external cold air flows into the integrated stove body through the opening. The hot air formed by the cold air passing through the components in the integrated stove body 1 can be sucked into the fan inlet 301 and finally flows to the air supply duct 400. On the one hand, the hot air flowing out through the second air supply outlet 402 can reduce the temperature in the integrated stove body 1 and ensure the heat dissipation effect of the integrated stove. On the other hand, the hot air flowing out through the first air supply outlet 401 can be supplied to the air inlet end of the ejector tube, which is equivalent to providing preheated primary air to the ejector tube, which can improve the combustion efficiency of the burner in the integrated stove.
