Description

Technical Field

[0001] The present invention relates to the technical field of household kitchenware, in particular to a gas stove capable of selecting a corresponding fire cover according to the type of pot. Background Art

[0002] The burning flame is generally multi-layered, with the outer flame having the highest temperature, so the bottom of the pot should be at a certain distance from the flame for better cooking effect, which can save energy and time. Currently, the pot is placed at a certain distance from the flame by a pot stand above the burner of the gas stove.

[0003] Existing pot stands typically consist of a base and multiple support plates secured to the base. Since there are various styles of pointed-bottom pots on the market, some with very sharp bottoms, they can hit the stove burner when placed, making the pot unstable or even tilting and falling. To make the pot stand suitable for both flat-bottomed and pointed-bottomed pots, the inner ends of the support plates are usually positioned closer to the center of the pot stand. While this allows both flat and pointed-bottom pots to be placed securely, the flames can reach the inner ends of the support plates when placing a flat pot, causing the support plates to come into contact with the flames and blacken the pot. To address this issue, existing patents address the need for existing pot stands to accommodate both flat pans and pointed-bottom pans. For example, Chinese utility model patent No. ZL202023081179.8 (authorization publication No. CN214549149U), titled "A Dual-Purpose Pot Stand Suitable for Pointed-Bottom Pans and Flat Pans," includes a pot stand base with a first bracket capable of supporting flat pans. A second bracket is hingedly connected to the first bracket, and the second bracket has a support end capable of supporting pointed-bottom pans. The first bracket is provided with a first locating portion for positioning the second bracket when the support end is rotated toward the center of the pot stand base, toward the inside of the first bracket, and a second locating portion for positioning the second bracket when the support end is rotated away from the center of the pot stand base, toward the outside of the first bracket. This pot stand can stably hold both pointed-bottom pans and flat pans, prevents flames from burning the inner end of the pot stand when using flat-bottom pans, and is compatible with various styles of pointed-bottom pans.

[0004] Even though the pot holder is suitable for both flat-bottomed pans and pointed-bottomed pans, the maximum combustion load for both flat-bottomed pans and pointed-bottomed pans is when the direction of fire is perpendicular to the bottom of the pan. However, the fire cover of the existing burner, whether it is an inner fire cover or an outer fire cover, is difficult to ensure that the corresponding fire direction can maintain a perpendicular relationship with different pan types, so further improvements are needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a gas stove that can select corresponding fire covers according to different pot types in response to the above-mentioned existing technical status, and is particularly suitable for flat-bottomed pots and pointed-bottomed pots.

[0006] The technical solution adopted by the present invention to solve the above technical problems is as follows: the gas stove includes a burner, characterized in that: the burner includes an inner burner body having a gas chamber, a gas pipe connected to the gas chamber and a mesh fire cover covering the open mouth of the inner burner body, and also includes: an outer burner body located outside the inner burner body and in an annular shape, the fire outlet direction of the outer burner body and the fire outlet direction of the mesh fire cover form an angle α, and 30°≤α≤75°, the inner burner body and the outer burner body are connected by a connecting channel, the connecting channel is connected to the gas pipe, and a driving member is provided in the connecting channel, the driving member can be directly triggered when a cookware is placed thereon, so as to selectively open or close a first gas inlet port connected to the inner burner body and a second gas inlet port connected to the outer burner body in the connecting channel.

[0007] The driving member can be arranged in various positions, but from the perspective of structural simplicity, preferably, the driving member is arranged on the pot support outside the outer burner body, and the driving member includes a driving rod that can be relative to one of the pot legs of the pot support, the head of the driving rod is at least partially exposed outside the pot leg, and the tail of the driving rod is provided with a switch member that can selectively open or close the first gas inlet port and the second gas inlet port.

[0008] Furthermore, the distance D1 that the head of the driving rod is exposed outside the pot support leg is 5 to 15 mm, the distance D2 between the driving rod and the inner end of the pot support leg is 20 mm to 50 mm, and the inner end of the pot support leg has an inclined surface, and an angle β is formed between the straight line where the inclined surface is located and the driving rod, and 20°≤β≤60°. In order to ensure that the driving member is not driven when the cookware is a pointed-bottom pot, it is necessary to ensure that the inclined surface of the pot support leg has a certain range requirement. To this end, the angle β is within the range of 20°≤β≤60°, which can adapt to various types of pointed pots and ensure that the solution of the present application can be implemented. Similarly, if there are certain requirements for the distance D2 between the driving rod and the inner end of the pot support leg, D2 cannot be too close. If it is too close, it may be mistakenly triggered even when the cookware is a pointed-bottom pot. Therefore, D2 is within the range of 20mm-50mm to ensure that the solution of the present application can be implemented. In addition, when the distance D1 of the head of the driving rod protruding from the pot support leg is 5-15mm, it can avoid the head of the driving rod from touching the bottom of the pointed-bottom pot too much and causing mistaken triggering. Combined with the limitations of the above three parameters, the driving member is directly triggered to move downward only when the driving rod is a flat pan.

[0009] In order to achieve automatic reset of the driving member when the pot is not placed on it, preferably, the tail of the driving rod is elastically arranged on the connecting channel, and there is a tendency for the head of the driving rod to always be at least partially exposed outside the pot support leg.

[0010] Furthermore, a connecting plate for connecting an elastic member is provided at the tail of the driving rod, the fixed end of the elastic member is connected to the connecting channel, and the free end of the elastic member is connected to the connecting plate, so that the head of the driving rod always has a tendency to be at least partially exposed outside the pot support leg.

[0011] In order to enable the switch member to selectively open or close the first gas inlet port and the second gas inlet port, preferably, the bottom of the connecting channel is provided with a first plate body forming the first gas inlet port together with the top of the connecting channel, and the top of the connecting channel is provided with a second plate body forming the second gas inlet port together with the bottom of the connecting channel. Correspondingly, the switch member is in a "U" shape with the opening facing downward, including a transverse portion connected to the tail of the driving rod and a first vertical portion and a second vertical portion connected to both ends of the transverse portion, the first vertical portion is used to cover the first gas inlet port and abut against the upper end edge of the first plate body, while the second vertical portion is kept in close proximity to the second plate body, and the transverse portion is at least partially provided with a connecting port communicating with the gas pipe and the first gas inlet port and the second gas inlet port.

[0012] In order to replenish the secondary air of the inner burner body, an air replenishment cavity is further formed between the inner burner body and the outer burner body, and the outer burner body is provided with radially arranged secondary air replenishment channels connected to the outside and the air replenishment cavity at intervals along the circumferential direction.

[0013] Compared with the prior art, the advantages of the present invention are that: an angle α is formed between the direction of the fire outlet of the outer burner body and the direction of the fire outlet of the mesh-type fire cover, and 30°≤α≤75°. In this way, by integrating the mesh-type fire cover whose fire outlet direction is perpendicular to the frying pan and the outer burner body whose fire outlet direction is perpendicular to the pointed-bottom pan on the gas stove, in order to automatically identify the frying pan and the pointed-bottom pan, the corresponding inner burner body and outer burner body are selected. When the pot is a pointed-bottom pan, the driving member is not driven, and the driving member only opens the second gas inlet port connected to the outer burner body, and the first gas enters The first gas inlet of the inner burner body is opened, and the second gas inlet is closed, so that the fire outlet of the inner burner body is perpendicular to the bottom of the frying pan. When the cookware is a flat pan, the driving member is directly triggered to move downward, thereby opening the first gas inlet connected to the inner burner body, and the second gas inlet is closed, so that the fire outlet of the inner burner body is perpendicular to the bottom of the frying pan. In this way, the user can control the gas on and off of different inner and outer burner bodies according to the cookware selected during the cooking process, so as to identify the pointed bottom pan and the flat pan and use different combustion holes for different pot types, thereby increasing the adaptability of the burner to cookware and improving energy utilization and efficiency.
