Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of household kitchen utensils, and particularly relates to a gas stove. BACKGROUND

[0002] In the existing gas stove, in order to facilitate the cleaning of the panel, the burner and the injection pipe are movably arranged above the panel. For example, the structure disclosed in the Chinese Utility Model Patent No. 201520219667.0, "Gas Stove Facilitating Cleaning" (authorized publication number CN204574135U), comprises a bottom plate (i.e. the above-mentioned panel), the bottom plate is provided with a mounting seat, the mounting seat is hingedly provided with a burner which can be flipped to the top of the bottom plate on the surface of the bottom plate, the mounting seat is further provided with a gas nozzle and a gas inlet connected with the gas nozzle, and the burner is provided with a gas injection pipe which is opposite to the gas nozzle when the burner is flipped to the surface of the bottom plate.

[0003] The above-mentioned patent has the following defects: 1. When the burner is flipped to the surface of the panel, the gas nozzle is still exposed on the panel, and it is difficult to clean the position of the gas nozzle, and the nozzle is easily wiped to cause the nozzle to be blocked; 2. The gas nozzle is arranged forwardly, i.e. facing the user, and there is a certain safety hazard. SUMMARY

[0004] The first technical problem to be solved by the present application is to provide a gas stove which is convenient to clean and can avoid nozzle blockage.

[0005] The second technical problem to be solved by the present application is to provide a gas stove which can improve the safety in use.

[0006] The third technical problem to be solved by the present application is to provide a gas stove which can further avoid liquid overflow and the like from entering the gas inlet end of the injection pipe or / and the nozzle.

[0007] The technical solution adopted by the present application to solve the above-mentioned first technical problem is as follows: a gas stove, comprising:

[0008] a panel;

[0009] a nozzle provided on the nozzle seat;

[0010] an injection pipe movably arranged above the panel in a transverse manner, the gas inlet end of the injection pipe being opposite to the nozzle;

[0011] characterized in that:

[0012] The top surface of the panel is concave downward at a position opposite to the ejector pipe to form a sink for the ejector pipe to be placed in, the sink has a first side wall extending upward and downward and opposite to the air inlet end of the ejector pipe, the nozzle is located outside the first side wall of the sink, and the first side wall has a through hole penetrating through the wall thickness thereof at a position opposite to the nozzle.

[0013] The up-and-down movement can be up-and-down movement, up-and-down rotation, or up-and-down movement plus rotation.

[0014] Thus, when cleaning is needed, the ejector pipe can be lifted upward to be away from the sink on the panel, and since the nozzle is located outside the first side wall of the sink, the cleaning of the sink is more convenient; meanwhile, since the nozzle is located outside the first side wall of the sink, the nozzle can be prevented from being blocked by wiping the nozzle when the sink is cleaned, and the nozzle can also be prevented from being blocked by liquid overflow.

[0015] To further solve the second technical problem, preferably, the air inlet end of the ejector pipe is arranged forward, and the nozzle is located at the front side of the first side wall of the sink and arranged backward. Thus, the nozzle arranged backward will not face the user directly, improving safety.

[0016] To further facilitate cleaning, preferably, the ejector pipe is arranged on the panel to be movable up and down. Thus, when the panel needs to be cleaned, the ejector pipe can be moved upward to be away from the panel, at this time, the panel only has the sink, facilitating cleaning.

[0017] To further solve the third technical problem, preferably, the air inlet end of the ejector pipe is opposite to the first side wall of the sink, and the top edge of the air inlet end of the ejector pipe extends horizontally outward to form a baffle, and the outer edge of the baffle is adjacent to or attached to the portion above the through hole of the first side wall of the sink. The baffle has the following functions: 1. The baffle is attached to the first side wall of the sink to position the ejector pipe; 2. The air inlet end of the ejector pipe can always form a gap with the first side wall of the sink, which is beneficial to the injection of air; 3. The baffle can block smoke above the air inlet end of the ejector pipe and the nozzle to prevent liquid overflow from entering the ejector pipe and the nozzle.

[0018] Preferably, the outer edge of the baffle is parallel to the first side wall of the sink.

[0019] The setting of the eave will affect the injection of the air above the air inlet end of the injection pipe to some extent. In addition, the injection pipe is located in the sink, and the injection air has a large resistance. In order to solve the technical problem, preferably, the direction of the air inlet end of the injection pipe is forward, the outer wall surface of the left side of the injection pipe is a first inclined surface inclined to the left from front to back, and / or the outer wall surface of the right side of the injection pipe is a second inclined surface inclined to the right from front to back. The setting of the first inclined surface or / and the second inclined surface effectively reduces the distance from the air inlet end of the injection pipe to the external environment on the left and right sides, reduces the resistance of the air on the left and right sides, and makes the injection air easier.

[0020] In order to further realize the positioning of the injection pipe, preferably, a pot support is further included, which is constrained together with the injection pipe and has pot supporting legs extending upward. The pot supporting legs are at least three, and each pot supporting leg is arranged in a whole along a circumferential direction between the air inlet end of the injection pipe.

[0021] The sink is rectangular with the above-mentioned first side wall and other three side walls. The other three side walls of the sink are adjacent to or abut against the corresponding pot supporting legs. In this way, the injection pipe is stably constrained in the sink and basically does not displace in the horizontal direction under the action of external force.

[0022] Preferably, the vertical distance between the top end of the pot supporting leg and the top surface of the panel is ≤30mm. Thus, it is easier to lift the pot and turn the pot, and the cooking experience is better.

[0023] Preferably, a burner is further included and arranged in the inner periphery of each pot supporting leg. The burner is constrained together with the injection pipe, the air outlet end of the injection pipe is relatively close to the burner and communicates with the burner, the air inlet end of the injection pipe extends outward along the radial direction of the burner, and is located at the outer periphery of each pot supporting leg.

[0024] Further, a bottom disc is further included, which has a bottom wall and a second side wall extending upward from the periphery of the bottom wall. The bottom wall and the second side wall jointly define a chamber with an open top.

[0025] The panel cover is arranged on the open top of the bottom disc.

[0026] The nozzle and the nozzle seat are arranged in the bottom disc.

[0027] Still further, the second side wall of the bottom disc is provided with a gas permeable hole penetrating through the wall thickness. External air can enter the bottom disc through the gas permeable hole, thereby facilitating the injection of air by the nozzle.

[0028] In the above-mentioned schemes, preferably, the sink has two and is arranged in parallel and spaced apart. The injection pipe and the corresponding nozzle and nozzle seat form a group, and there are two groups and each group is arranged corresponding to the sink.

[0029] The existing panel, especially the stainless steel panel, is prone to deformation. Therefore, preferably, a convex part is arranged between two adjacent grooves, and the upper surface of the convex part is below the top surface of the panel. The panel structure can strengthen the panel strength and reduce the deformation of the panel.

[0030] In the above-mentioned solutions, in order to further facilitate cleaning, preferably, a first section of needle tube and a second section of needle tube are provided, the first section of needle tube is fixed relative to the panel, the second section of needle tube is fixed relative to the ejector tube, the first section of needle tube is provided with a first plug-in part, and the second section of needle tube is provided with a second plug-in part which can be plugged with the first plug-in part from top to bottom, so that when the ejector tube is placed in the groove from top to bottom, the first plug-in part is plugged with the second plug-in part. In this way, when the ejector tube is lifted upwards, the first and second sections of needle tube can be separated, and when the ejector tube is placed downwards, the first and second sections of needle tube are combined, so that the discharge ignition can be realized.

[0031] The first and second sections of needle tube can be combined by contact between two end points, but the end point contact has the defects of misalignment and unstable structure. In order to improve the structural stability between the first and second sections of needle tube, preferably, the first end of the first section of needle tube is provided with an outwardly extending conductive seat, the upper surface of the conductive seat is formed with a groove with a notch upward as the first plug-in part, and the groove is strip-shaped and extends along the longitudinal direction of the second section of needle tube.

[0032] The second end of the second section of needle tube is inserted into the groove as the second plug-in part, and the local part of the outer peripheral wall of the second end is downwardly opposite to and in contact with the inner wall of the groove.

[0033] In this way, by inserting the second end of the second section of needle tube into the groove of the conductive seat, the two sections of needle tube can be constrained together, and the two sections of needle tube constrained together are in surface-to-surface contact, which has high stability and can effectively avoid accidental misalignment of the two sections of needle tube.

[0034] The needle tube can be hollow or solid structure.

[0035] Preferably, the second end of the second section of needle tube is located outside the air inlet end of the ejector tube, and the directions of the two are consistent, the first section of needle tube is arranged outside the first side wall of the groove, and the conductive seat extends into the groove through the through hole. Since the first section of needle tube is located outside the first side wall of the groove, the cleaning of the groove is more convenient; at the same time, the first section of needle tube can be prevented from being polluted by liquid overflow and the like.

[0036] Compared with the prior art, the advantages of the present invention are: by arranging a trough on the top surface of the panel, and arranging a through hole on the first side wall of the trough, and arranging the nozzle outside the first side wall of the trough, when cleaning is required, the ejection tube can be lifted upward to make the ejection tube away from the trough on the panel. Since the nozzle is located outside the first side wall of the trough, cleaning the trough is more convenient; at the same time, since the nozzle is located outside the first side wall of the trough, clogging of the nozzle caused by wiping the nozzle when cleaning the trough can be avoided, and clogging of the nozzle due to overflow can be avoided.

[0048] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0049] Example 1:

[0050] like Figures 1-10As shown, it is a preferred embodiment one of a gas stove of the present application, which comprises a panel 3, a nozzle 4, a combustion assembly, a pot support 6, a base plate 8 and a segmented ignition needle.

[0051] The base plate 8 has a bottom wall 81 and a second side wall 82 extending upward from the periphery of the bottom wall 81, and the bottom wall 81 and the second side wall 82 together define a top-opened cavity. The side of the base plate facing the user is the front side. The second side wall 82 of the front side of the base plate 8 is provided with air-permeable holes 820 penetrating the wall thickness.

[0052] The bottom surface of the panel 3 is downwardly covered on the top opening of the base plate 8. The top surface of the panel 3 is downwardly recessed to form two left and right parallel and spaced-apart sunken grooves 30. The adjacent two sunken grooves 30 are a raised portion 32, and the upper surface of the raised portion 32 is below the top surface of the panel 3. At the same time, each sunken groove 30 is rectangular, and the front side has an upper and lower extending first side wall 31, and the first side wall 31 has a through hole 310 penetrating the wall thickness thereof.

[0053] The above-mentioned nozzle 4 is arranged on the nozzle seat 40, and the nozzle seat 40 and the two left and right nozzles 4 thereon form a group, and there are two groups respectively located in the front side of the first side wall 31 of the corresponding sunken groove 30 and inside the base plate 8, and each nozzle 4 is arranged rearward and opposite to the corresponding through hole 310.

[0054] The above-mentioned combustion assembly has two groups and is movably arranged in the corresponding sunken groove 30. The combustion assembly comprises a burner 7 and a draft tube 5 which is constrained together with the burner 7 and extends forward and backward. The burner 7 has an inner ring cavity, an outer ring cavity arranged around the periphery of the inner ring cavity in the circumferential direction, and an annular cavity 70 formed between the inner ring cavity and the outer ring cavity and penetrating upward and downward, which is used for the supplement of secondary air. When the liquid overflow or dirt accumulates on the panel through the annular cavity, the combustion assembly is lifted upward to wipe the panel. The draft tube 5 has two left and right parallel and integrated draft tubes 5. The front ends of the two draft tubes 5 are air inlet ends 5a, which are spaced apart from the first side wall 31 of the corresponding sunken groove 30 and opposite to the corresponding nozzle 4, and the top edges of the air inlet ends 5a of the two draft tubes 5 extend horizontally outward to form a eave 51, the outer edges of the eave 51 extend left and right, are parallel to the first side wall 31 of the sunken groove 30, and are adjacent to or in contact with the part above the through hole 310 of the first side wall 31 of the sunken groove 30. The rear ends of the two draft tubes 5 are air outlet ends 5b and are respectively connected to the inner ring cavity and the outer ring cavity of the burner 7.

[0055] As shown, it is a preferred embodiment one of a gas stove of the present application, which comprises a panel 3, a nozzle 4, a combustion assembly, a pot support 6, a base plate 8 and a segmented ignition needle. Figure 1 、 2The pot support 6 includes a support ring 60 and pot supporting legs 61 extending upward from the support ring 60. The pot supporting legs 61 are four in number and are arranged at equal intervals along the circumference of the support ring 60. The support ring 60 is arranged below the burner 7 and is connected to the burner 7 by means of screws. Each of the pot supporting legs 61 is located at the periphery of the burner 7. The portion between the two ejector pipes 5 arranged side by side is provided with a through hole 500 extending upward and downward. The through hole 500 is arranged to avoid the ejecting passage inside the ejector pipe 5. One of the four pot supporting legs 61 extends along the length direction of the ejector pipe 5 and is inserted into the through hole 500 with the top end located above the through hole 500. The other three pot supporting legs 61 are adjacent to or in contact with the rear side wall and the left and right side walls of the sink 30. In this embodiment, the vertical distance between the top end of each pot supporting leg 61 and the top surface of the panel 3 is less than or equal to 30 mm.

[0056] As shown in Figures 8-10 , the segmented ignition needle includes a first segment needle tube 1 and a second segment needle tube 2. The first segment needle tube 1 is fixed relative to the panel 3 and is arranged inside the sink 30 in front of the first side wall 31 and inside the base plate 8. The first end 11 of the first segment needle tube 1 faces backward and is provided with a conductive seat 12. The conductive seat 12 extends into the sink 30 through the through hole 310. The upper surface of the conductive seat 12 is formed with a groove 120 with a notch facing upward. The groove 120 is strip-shaped and extends forward and backward. The notch 121 is arranged at the notch edge of the groove 120 and is close to the first end 11 of the first segment needle tube 1. The second segment needle tube 2 is fixed relative to the ejector pipe 5 (the bottom wall between the two ejector pipes 5 is provided with a linear groove 54 extending along the length direction of the ejector pipe 5. The second segment needle tube 2 is partially embedded in the linear groove 54, thereby achieving the fixation of the second segment needle tube 2 relative to the ejector pipe 5). The second end 21 of the second segment needle tube 2 faces forward and is located at the front side of the air inlet end 5a of the ejector pipe 5. The second end 21 of the second segment needle tube 2 is downwardly inserted into the groove 120. The outer peripheral wall of the second end 21 of the second segment needle tube 2 is partially downwardly in contact with the inner wall of the groove 120. When the ejector pipe 5 is arranged in the sink 30 from top to bottom, the second segment needle tube 2 is inserted into the first segment needle tube 1.

[0057] At the same time, as shown in Figure 1 , 2 , and Figures 8-10As shown, the outer peripheral wall of the second end 21 of the second section needle tube 2 has a first portion 221 upward in the circumferential direction and a second portion 222 downward in the circumferential direction. The segmented ignition needle further comprises a first insulating block 14 and a second insulating block 13. The second insulating block 13 is provided with a second insertion hole 130, the second section needle tube 2 is longitudinally arranged in the second insertion hole 130, and the second insulating block 13 is provided with a second notch 131 corresponding to the position of the second portion 222 of the second section needle tube 2, so that the second portion 222 is exposed outside the second insertion hole 130 and inserted into the groove 120, and the first portion 221 is hidden in the second insertion hole 130. The first insulating block 14 is provided with a first insertion hole 140, the first section needle tube 1 and the conductive seat 12 are longitudinally arranged in the first insertion hole 140, and the first insulating block 14 is provided with a first notch 141 corresponding to the position of the slot of the groove 120, so that the slot of the groove 120 is located outside the first insertion hole 140. At the same time, the first notch 141 of the first insulating block 14 is arranged to enable the portion of the second insulating block 13 corresponding to the first portion 221 of the second section needle tube 2 to be seated therein. In this way, by inserting the portion of the second insulating block 13 corresponding to the first portion 221 into the first notch 141 of the first insulating block 14, the contact of the two section needle tubes can be achieved, and the contact position of the two section needle tubes will not be offset. At the same time, due to the size of the insulating block being larger than the size of the needle tube, the insertion operation of the two large-size insulating blocks is more convenient. After insertion, the second insulating block 13 and the first insulating block 14 can protect the insertion part of the two section needle tubes, effectively avoiding oil pollution.

[0058] In this way, when cleaning is needed, the pot support 6 can be lifted upward, so that the ejector pipe 5 is away from the sink groove 30 on the panel 3. Since the nozzle 4 is located outside the first side wall of the sink groove, the cleaning of the sink groove 30 is more convenient. At the same time, since the nozzle 4 is located outside the first side wall of the sink groove, the nozzle 4 can be prevented from being blocked due to wiping during cleaning of the sink groove 30, and nozzle blockage during overflow can also be avoided.

[0059] Embodiment two:

[0060] As Figure 11 shown, it is a preferred embodiment two of the gas stove of the present application, which is basically the same as embodiment one, and the difference lies in that in this embodiment, the outer wall surface of the left side of the whole of the two side-by-side arranged ejector pipes 5 is a first inclined surface 52 which is inclined to the left from front to back, and the outer wall surface of the right side is a second inclined surface 53 which is inclined to the right from front to back.

[0061] Directional terms as used in describing the various example structural parts and elements of the application, such as "front", "back", "up", "down", "left", "right", "side", "top", "bottom", and the like are made only for the purpose of convenience in describing the illustrations and are determined based on the example orientation of the illustrations shown in the drawings. Since the embodiments disclosed herein can be positioned in different orientations, these directional terms are used only for the purpose of description and should not be construed as limiting, such as "up", "down" are not necessarily limited to the direction opposite or consistent with the direction of gravity.
