Description

Technical Field

[0001] The present invention relates to a gas stove with a movable burner head. Background Art

[0002] A gas stove refers to a kitchen appliance that directly heats with gaseous fuels such as liquefied petroleum gas (liquid), artificial coal gas, and natural gas.

[0003] When the gas stove is working, gas enters the stove from the gas inlet pipe, passes through the adjustment of the gas valve (adjusted by the user through the knob) and enters the burner head. At the same time, a part of air (this part of air is called primary air) is mixed. These mixed gases are ejected from the fire holes of the burner and are ignited by the ignition device to form a flame (the air required for combustion is called secondary air). These flames are used to heat the cookware placed on the pot support.

[0004] In the existing gas stoves, the burner heads are fixed on the stove body, and the distance between the burner heads is relatively far. Users cannot freely increase the number of burner heads and freely adjust the positions of the burner heads according to the cooking situation, and cannot meet the various cooking needs of users. Summary of the Invention

[0005] The purpose of the present invention is to provide a gas stove with a movable burner head that can freely adjust the position of the burner head and the position of the flame.

[0006] The purpose of the present invention is achieved as follows:

[0007] A gas stove with a movable burner head includes a stove body, at least one burner head, a gas valve, a water pan assembly, and a burner cap. The gas valve is arranged in the stove body. An installation opening is formed on the surface of the stove body. The water pan assembly is stacked by multiple water pans. The outer diameter of the previous water pan is larger than that of the next water pan, and the inner diameter of the previous water pan is larger than that of the next water pan. The previous water pan is clamped on the installation opening, and the next water pan is stacked on the previous water pan. The centers of the previous water pan and the next water pan are the same. The part where the ring width of the previous water pan exceeds that of the next water pan forms the moving space of the next water pan;

[0008] The burner head is movably arranged in the stove body. The gas inlet pipe of the burner head is connected to the gas valve through a hose. The burner of the burner head passes through the inner circle of the last water pan and extends out of the stove body to connect the burner cap. When the position of the next water pan changes, the position of the burner head changes accordingly.

[0009] The part where the ring width of the previous water pan exceeds that of the subsequent water pan forms a moving space for the subsequent water pan. The burner of the stove passes through the inner circle of the subsequent water pan and extends outside the stove body to connect to the burner cap. When the position of the subsequent water pan changes, the position of the burner follows. When the user pushes the subsequent water pan to move within the moving space, the position of the subsequent water pan can be adjusted, and the position of the burner follows, thus changing the position of the burner and adjusting the flame position to meet different cooking needs of the user.

[0010] The object of the present invention can also be solved by the following technical measures:

[0011] As a more specific solution, it further includes an elastic component. The elastic component includes a burner support, a spring, a bolt, and a fixing piece. A notch is opened on the bottom wall of the stove body corresponding to the installation opening. The fixing piece is located outside the stove body near the notch. The burner support is arranged inside the stove body and below the installation opening. The bolt passes through the fixing piece, the head of the bolt is located outside the stove body, and the tail of the bolt extends into the stove body to connect to the burner support. The spring is sleeved on the bolt. One end of the spring abuts against the head of the bolt, and the other end of the spring abuts against the fixing piece. The spring upwardly supports the fixing piece, and the notch limits the moving distance of the fixing piece through the bolt. The burner is connected to the burner support.

[0012] The elastic force of the spring always keeps pushing the fixing piece upward, and the fixing piece keeps tightly attached to the bottom wall of the stove body to prevent the burner from loosening. When the user needs to move the burner forward, backward, left, or right, since there is no assembly relationship between the fixing piece and the stove body, the fixing piece can move freely. Moreover, since the burner is connected through the burner support and the bolt, the burner automatically moves following the fixing piece, and the position adjustment of the burner is very simple.

[0013] Furthermore, by using a spring, when the user pulls the burner upward, the water cover assembly does not bear the pressure of the burner, and it is easy for the user to push the water cover to move for adjusting the position of the burner. When the user releases the burner, the spring resets, and the spring pulls the burner downward to press the water cover assembly, and the water cover assembly bears the pressure, making it difficult for the user to push the water cover to move. Thus, when the burner is working, the water cover will not easily loosen, resulting in a change in the flame position, greatly improving the safety of using the gas stove.

[0014] As a more specific solution, a lower limit ring is provided along the circumferential direction on the outer circular bottom surface of each water pan, and an upper limit ring is provided along the circumferential direction on the inner circular surface of each water pan.

[0015] As a more specific solution, the latter-stage water tray is stacked on the former-stage water tray. When the latter-stage water tray moves towards the center of the circle, the upper limit ring of the former-stage water tray obstructs the lower limit ring of the latter-stage water tray from moving towards the center of the circle, thereby restricting the moving distance of the latter-stage water tray. The upper limit ring of the former-stage water tray obstructs the lower limit ring of the latter-stage water tray from moving towards the center of the circle, thereby restricting the moving distance of the latter-stage water tray and defining the moving position of the burner head.

[0016] As a more specific solution, the water tray assembly includes a first-stage water tray, a second-stage water tray, a third-stage water tray, and a fourth-stage water tray. The first-stage water tray, the second-stage water tray, the third-stage water tray, and the fourth-stage water tray are stacked in sequence from bottom to top. The first-stage water tray restricts the moving distance of the second-stage water tray, the second-stage water tray restricts the moving distance of the third-stage water tray, the third-stage water tray restricts the moving distance of the fourth-stage water tray, and the burner of the burner head extends out of the furnace body through the inner circle of the fourth-stage water tray.

[0017] As a more specific solution, four symmetrically arranged mounting openings are formed on the surface of the furnace body. A water tray assembly is installed at each mounting opening. Four burner heads and four gas valves are arranged inside the furnace body. The intake pipes of the four burner heads are all connected to the corresponding gas valves through hoses, and the burners of the four burner heads extend out of the inner circles of the latter-stage water trays of the corresponding water tray assemblies.

[0018] As a more specific solution, a knob is arranged on the surface of the furnace body. The knob is connected to the corresponding gas valve to adjust the intake amount of gas.

[0019] As a more specific solution, it further includes a hose bracket. The hose is fixed inside the furnace body through the hose bracket. One end of the hose is connected to the intake pipe of the burner head, and the other end of the hose is connected to the gas valve. The burner head and the gas valve are connected through a hose. Since the hose is flexible, when the user stretches the burner head up and down or pushes and pulls the burner head left and right, the connection between the burner head and the gas valve remains unobstructed, improving the practicality of the gas stove.

[0020] As a more specific solution, the hose is a corrugated pipe, and the water tray is a ring.

[0021] As a more specific solution, the furnace body includes a bottom shell and a glass panel. The glass panel is installed on the bottom shell, and the mounting opening is formed on the glass panel.

[0022] The beneficial effects of the present invention are as follows:

[0023] In the present invention, the part where the ring width of the previous water tray exceeds that of the subsequent water tray forms the moving space for the subsequent water tray. The burner of the stove head passes through the inner circle of the subsequent water tray and extends outside the stove body to connect with the burner cap. When the position of the subsequent water tray changes, the position of the stove head changes accordingly. When the user pushes the subsequent water tray to move within the moving space range, the position of the subsequent water tray can be adjusted, and the position of the stove head changes accordingly, thereby changing the position of the stove head and adjusting the flame position to meet different cooking needs of the user.

[0024] In the present invention, the elastic force of the spring always keeps pushing the fixing piece upward, and the fixing piece keeps closely attached to the bottom wall of the stove body to prevent the stove head from loosening. When the user needs to move the stove head forward, backward, left, or right, since there is no assembly relationship between the fixing piece and the stove body, the fixing piece can move freely. Moreover, since the stove head is connected by the stove head bracket and bolts, the stove head moves automatically following the fixing piece, and the position adjustment of the stove head is very simple.

[0025] In the present invention, by adopting a spring, when the user pulls the stove head upward, the water cover assembly does not bear the pressure of the stove head, and it is easy for the user to push the water cover to move for facilitating the adjustment of the stove head position. When the user releases the stove head, the spring resets, and the spring pulls the stove head to press down the water cover assembly, and the water cover assembly bears the pressure, making it difficult for the user to push the water cover to move. Thus, when the stove head is working, the water cover will not easily loosen and cause the change of the flame position, greatly improving the safety of using the gas stove.

[0026] In the present invention, the stove head and the gas valve are connected by a hose. Since the hose has flexibility, when the user stretches the stove head up and down or pushes and pulls the stove head left and right, the connection between the stove head and the gas valve remains unobstructed, improving the practicality of the gas stove.

[0050] The fourth - stage water tray 44 is stacked on the third - stage water tray 43. The centers of the fourth - stage water tray 44 and the third - stage water tray 43 are the same. The part of the ring width of the third - stage water tray 43 that exceeds the ring width of the fourth - stage water tray 44 forms the moving space of the fourth - stage water tray 44.

[0051] The elastic component 9 includes a burner support 91, a spring 92, a bolt 93 and a fixing piece 94. A notch 14 is formed in the bottom wall of the furnace body 1 corresponding to the position of the mounting opening 13. The fixing piece 94 is located outside the furnace body 1 near the notch 14. The burner support 91 is arranged inside the furnace body 1 and below the mounting opening 13. The bolt 93 passes through the fixing piece 94. The head of the bolt 93 is located outside the furnace body 1, and the tail of the bolt 93 extends into the furnace body 1 to connect the burner support 91. The spring 92 is sleeved on the bolt 93. One end of the spring 92 abuts against the head of the bolt 93, and the other end of the spring 92 abuts against the fixing piece 94. The spring 92 upwardly supports the fixing piece 94. The notch 14 restricts the moving distance of the fixing piece 94 through the bolt 93. The burner 2 is connected to the burner support 91.

[0052] The elastic force of the spring 92 always keeps pushing the fixing piece 94 upward, and the fixing piece 94 keeps tightly attached to the bottom wall of the furnace body 1 to prevent the burner 2 from loosening.

[0053] The hose support 8 is fixed inside the furnace body 1. The hose 7 passes through the hose support 8. The hose support 8 restricts the hose 7 inside the furnace body 1. The hose 7 is a corrugated pipe.

[0054] The gas valve 3 is arranged inside the furnace body 1, and the knob 6 is arranged on the surface of the furnace body 1 to connect to the gas valve 3. The knob 6 controls the intake volume of the gas valve 3. The burner head 2 is installed on the burner head bracket 91. One end of the hose 7 communicates with the gas valve 3, and the other end of the hose 7 communicates with the intake pipe 22 of the burner head 2. The burner divider 21 of the burner head 2 passes through the inner circle of the fourth-stage water pan 44 and extends outside the furnace body 1 to connect to the burner cap 5. When the fourth-stage water pan 44 moves, it drives the burner head 2 to move.

[0055] In this embodiment, the glass panel 12 of the furnace body 1 is provided with four symmetrically arranged mounting openings 13. Each mounting opening 13 is provided with a water pan assembly 4. Corresponding to each mounting opening 13 of the furnace body 1, there is a burner head 2, a gas valve 3, and a knob 6, forming a gas stove with four movable burner heads 2.

[0056] Working principle:

[0057] When the user pulls up the burner head 2, the spring 92 is compressed, and the burner head 2 rises. The first-stage water pan 41, the second-stage water pan 42, the third-stage water pan 43, and the fourth-stage water pan 44 no longer bear the pressure of the burner head 2. At this time, the user can easily move any one of the first-stage water pan 41, the second-stage water pan 42, the third-stage water pan 43, and the fourth-stage water pan 44. When the position of any one of the water pans changes, it changes the position of the fourth-stage water pan 44, and the position of the burner head 2 changes following the position of the fourth-stage water pan 44, thereby adjusting the position of the burner head 2, enabling the burner head to move forward, backward, left, and right, and changing the flame spraying angle.

[0058] Since there is no assembly relationship between the fixing piece 94 and the furnace body 1, the fixing piece 94 can move freely. Moreover, the burner head 2 is connected through the burner head bracket 91 and the bolt 93. Therefore, the burner head 2 moves automatically following the fixing piece 94, and the position adjustment of the burner head 2 is very simple.

[0059] After the user adjusts the position of the burner head 2, the user releases the burner head 2, and the spring 92 remains in a compressed state. The first-stage water pan 41, the second-stage water pan 42, the third-stage water pan 43, and the fourth-stage water pan 44 bear the pressure of the burner head 2. At this time, it is very difficult for the user to move any one of the first-stage water pan 41, the second-stage water pan 42, the third-stage water pan 43, and the fourth-stage water pan 44. Moreover, the elastic force of the spring always acts on the fixing piece 94, making the fixing piece 94 keep close to the furnace body 1, avoiding the loosening of the burner head 2, and greatly improving the use safety of the gas stove.
