Description

Technical Field

[0001] The present invention relates to the field of gas stoves, and in particular to a gas stove. Background Art

[0002] A gas stove is a kitchen appliance that uses direct flames to heat the kitchen using a gaseous fuel, such as liquefied petroleum gas (liquid), artificial coal gas, or natural gas. With the continuous improvement of people's living standards, gas stoves have become an indispensable kitchen appliance in daily life, and people's expectations for gas stoves are becoming increasingly higher. To meet the needs of modern families for gas stoves, double-burner gas stoves are favored by users for their high efficiency, energy saving, safety, and versatility. Double-burner gas stoves feature two burners, each equipped with an independent control switch for independent control and operation.

[0003] The existing double-burner gas stove has two burners, which are usually symmetrically arranged along the left and right directions of the bottom shell.

[0036] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] See also Figure 1-3 The present invention provides a gas stove 100 for cooking dishes and processing food by converting chemical energy of gas into thermal energy to meet user needs. The gas stove 100 includes a housing 110 , a first burner 120 , and a second burner 130 .

[0038] The housing 110 of the gas stove 100 not only needs to fit the overall style of the user's kitchen but also has a housing cavity 110a, which provides the necessary space and support for the first and second burners 120, 130 installed within the housing cavity 110a, ensuring that the first and second burners 120, 130 are properly installed and function properly. The housing 110 has a longitudinal direction AA and a width direction BB that are perpendicular to each other, and has a front side 1121a and a rear side 1122a that are oppositely disposed along the width direction BB.

[0039] Specifically, the housing 110 includes a bottom shell structure 111 and a side shell structure 112 disposed around the bottom shell structure 111. The first burner 120 and the second burner 130 are both disposed on the bottom shell structure 111. The side shell structure 112 includes a front shell 1121 and a rear shell 1122 disposed opposite each other along the width direction BB. The front shell 1121 has a front side edge 1121a, and the rear shell 1122 has a rear side edge 1122a. The bottom shell structure 111 and the side shell structure 112 together enclose a accommodating cavity 110a. The bottom shell structure 111 and the side shell structure 112 provide stable support and protection for the first burner 120 and the second burner 130, enhancing the stability of the overall structure and providing additional protection to prevent users from accidentally touching high-temperature components.

[0040] The primary function of the first burner 120 and the second burner 130 is to mix gas with air for efficient combustion. At least a portion of the first burner 120 and at least a portion of the second burner 130 are mounted within the accommodating cavity 110a and arranged along the longitudinal direction AA. This allows for a certain distance between the first burner 120 and the second burner 130 along the longitudinal direction AA, thereby allowing for the placement of cookware of different sizes. This allows for the first burner 120 and the second burner 130 to operate independently of each other without interfering with each other, allowing the user to simultaneously cook different foods using different cookware on the first burner 120 and the second burner 130.

[0041] Specifically, the first burner 120 includes a first burner head 121 and a first ejector pipe 122 connected to each other. The second burner 130 includes a second burner head 131 and a second ejector pipe 132 connected to each other. The first burner head 121 and the second burner head 131 are typically made of metal and have flame holes that eject a mixture of gas and air to form a flame. The first ejector pipe 122 and the second ejector pipe 132 are typically connected to a gas pipeline, responsible for transporting gas from the gas pipeline to the first burner head 121 and the second burner head 131, respectively.

[0042] In order to solve the problem that the layout of the first burner 120 and the second burner 130 in the accommodating cavity 110a causes the gas stove 100 to occupy a large space, since the first burner 121 and the second burner 131 are usually annular structures, changing the installation position of the first burner 121 and the second burner 131 in the accommodating cavity 110a by rotating cannot achieve its main function of improving the utilization rate of the accommodating cavity 110a.

[0043] In some embodiments, the first ejector tube 122 extends toward the side where the second burner 130 is located, and its distance from the front side 1121a in the width direction BB gradually increases. The second ejector tube 132 extends toward the side where the first burner 120 is located, and its distance from the front side 1121a in the width direction BB gradually decreases. Compared to the related art layout in which the ejector tubes of one burner and the ejector tubes of the other burner are both parallel to the front side 1121a, the layout of this embodiment makes the first ejector tube 122 and the second ejector tube 132 more compact in the length direction AA, thereby reducing the space occupied by the gas stove 100 in the length direction AA. Furthermore, compared to the related art layout in which the ejector tubes of one burner and the ejector tubes of the other burner are both inclined in the shape of an "eight" and symmetrical along the width direction BB of the bottom shell, the layout of this embodiment makes the first ejector tube 122 and the second ejector tube 132 more compact in the width direction BB, thereby reducing the space occupied by the gas stove 100 in the length direction AA.

[0044] It is understandable that part or all of the first burner 120 and the second burner 130 are installed in the accommodating cavity 110a. When the first burner 120 and the second burner 130 are all installed in the accommodating cavity 110a, they are submerged burners, which can provide a smoother and neater appearance of the gas stove 100. However, due to the overall submerged structural characteristics of the submerged burner, it occupies a larger internal space of the shell 110 and is prone to interference with other structures in the accommodating cavity 110a. This embodiment optimizes the layout of the first ejector pipe 122 and the second ejector pipe 132 to more effectively utilize the space of the accommodating cavity 110a, so that the gas stove 100 can reduce the occupation of the kitchen space (specifically the stove space) while maintaining the same function. When the first burner 120 and the second burner 130 are submerged burners, the effect is more significant.

[0045] In some embodiments, the first burner 121, the first ejector tube 122, the second burner 131, and the second ejector tube 132 are all made of stainless steel. Specifically, stainless steel sheets are made. Compared to burners and ejector tubes made of copper alloys and aluminum alloys, stainless steel is inexpensive, consumes less energy, and causes less environmental pollution, thus complying with the national green manufacturing concept.

[0046] See also Figure 3-4 In some embodiments, the gas stove 100 further includes a valve assembly 140 connected to the first ejector tube 122. This valve assembly 140 is primarily used to control the on / off flow of the gas circuit and regulate gas flow. Specifically, it is responsible for opening or closing the gas supply to the first burner 120 and the second burner 130, turning the ignition device on or off, and adjusting the output power of the first burner 120 and the second burner 130.

[0047] Since the distance between the first ejector tube 122 and the front side 1121a gradually increases from the first furnace head 121 to the second furnace head 131, a region is left vacant to form the first avoidance zone 110b (e.g. Figure 4-5 The area shown by the middle dotted line), that is, a first avoidance area 110b is formed between the first ejection tube 122 and the front side shell 1121, and the valve body assembly 140 is installed in the first avoidance area 110b, which effectively avoids interference between the first ejection tube 122 and the valve body assembly 140. While ensuring a safe distance between the first ejection tube 122 and the valve body assembly 140, the valve body assembly 140 is allowed to be more compactly installed on the bottom shell structure 111, thereby improving the space utilization of the accommodating cavity 110a.

[0048] See also Figure 6 In some embodiments, the central axis of the first ejector tube 122 is collinear or parallel to the central axis of the second ejector tube 132. Furthermore, the first burner 120 and the second burner 130 can be arranged in a centrally symmetrical manner. The centrally symmetrical layout usually makes the various structures more compact and harmonious, thereby improving the aesthetic appeal of the layout of the first burner 120 and the second burner 130.

[0049] Furthermore, the central axes of the first ejection tube 122 and the second ejection tube 132 are both arranged at an angle with the front side 1121a. In actual use, by adjusting the angle α between the first ejection tube 122 and the second ejection tube 132 and the front side 1121a, when the angle α is larger, the space occupied by the first burner 120 and the second burner 130 in the length direction AA can be reduced, and when the angle is smaller, the space occupied by the first burner 120 and the second burner 130 in the width direction BB can be reduced. By flexibly adjusting the angle between the first ejection tube 122 and the second ejection tube 132 and the front side wall, personalized customization is possible to meet the needs of different stove sizes.

[0050] It is understandable that the central axis of the first ejection tube 122 and the central axis of the second ejection tube 132 can also be arranged in a non-collinear and non-parallel manner, that is, the central axis of the first ejection tube 122 and the central axis of the second ejection tube 132 produce an intersection. According to actual conditions, the angle between the first ejection tube 122 and the second ejection tube 132 and the front side 1121a can be adjusted to achieve the effect of reducing the occupied space of the gas stove 100 without sacrificing function.

[0051] In some embodiments, as Figure 5 As shown, the included angle α between the central axis of first ejector tube 122 and front side 1121a satisfies the following conditions: 0 < α ≤ 30°. The included angle β between the central axis of second ejector tube 132 and front side 1121a satisfies the following conditions: 0 < β ≤ 30°. This helps shorten the projections of first and second ejector tubes 122 and 132 along the longitudinal direction AA, thereby reducing the overall length of gas stove 100 and saving space.

[0052] Furthermore, α and β further satisfy: α=β. Preferably, α and β are 20°, which ensures that there is no interference between the first ejection tube 122 and the second ejection tube 132, reduces the occupied space in the length direction AA, and improves the space utilization of the accommodating chamber 110a.

[0053] See also Figure 4 In some embodiments, one or more first ejection tubes 122 are provided, and the multiple first ejection tubes 122 are arranged at intervals along the circumference of the first burner 121, and the first ejection tubes 122 are arranged in a one-to-one correspondence with the first burner 121; one or more second ejection tubes 132 are provided, and the multiple second ejection tubes 132 are arranged at intervals along the circumference of the second burner 131, and the second ejection tubes 132 are arranged in a one-to-one correspondence with the second burner 131; the multiple first ejection tubes 122 and the multiple second ejection tubes 132 can significantly improve the combustion efficiency and also provide more adjustment options. Users can adjust the gas flow according to cooking needs to achieve different cooking effects.

[0054] Among them, multiple first ejection tubes 122 and multiple second ejection tubes 132 are arranged alternately along the width direction BB. The alternating arrangement can make more effective use of space. There is no interference between the multiple first ejection tubes 122 and the multiple second ejection tubes 132. They can be arranged closely facing each other, reducing the space occupied by the gas stove 100, and are suitable for kitchens with smaller areas.

[0055] It is understandable that at least one first ejection tube 122 and at least one second ejection tube 132 may be coaxially arranged, and this application does not limit this.

[0056] When two first ejector tubes 122 are provided, Figure 6 and Figure 7As shown, the first burner 121 includes a first inner burner 1211 and a first outer burner 1212 disposed around the first inner burner 1211. The first ejector pipe 122 includes a first inner ejector pipe 1221 connected to the first inner burner 1211 and a first outer ejector pipe 1222 connected to the first outer burner 1212. The second burner 131 includes a second inner burner 1311 and a second outer burner 1312 disposed around the second inner burner 1311. The second ejector pipe 132 includes a second inner ejector pipe 1321 connected to the second inner burner 1311 and a second outer ejector pipe 1322 connected to the first outer burner 1212. The provision of the first and second outer ejector pipes 1222 and 1322 can provide a more uniform flame distribution, particularly on larger or multi-layer burners, helping to achieve a more uniform heating effect. Furthermore, users can adjust the size of the inner and outer flames according to cooking needs, providing more flexible firepower control.

[0057] The first outer ejection tube 1222 and the second outer ejection tube 1322 are coaxially arranged. This coaxial arrangement can reduce the space occupied in the width direction BB because the two outer ejection tubes share the same axis, thereby placing the first outer ejection tube 1222 and the second outer ejection tube 1322 on the same straight line, making the arrangement more compact in the width direction BB. The first inner ejection tube 1221 and the second inner ejection tube 1321 are located on opposite sides of the coaxial first and second outer ejection tubes 1222, 1322, respectively, reducing interference between the first and second inner ejection tubes 1221, 1321.

[0058] See also Figure 2 as well as Figure 5 In some embodiments, the gas stove 100 further includes a panel 160, which is covered on the accommodating cavity 110a and has a first cooktop 160a and a second cooktop 160b formed on the panel 160. The first cooktop 121 is disposed in the first cooktop 160a, and the second cooktop 131 is disposed in the second cooktop 160b. A first connecting line 170 is connected between the midpoint of the first burner 121 and the midpoint of the second burner 131. The first connecting line 170 is arranged parallel to the front side 1121a, that is, the first cooktop 160a and the second cooktop 160b are symmetrically arranged with respect to the width direction, so that the left and right structures of the gas stove 100 are more balanced, providing a balanced appearance, making the gas stove 100 look neater and more beautiful, and the user can conveniently move cookware in a straight line between the first burner 121 and the second burner 131 when cooking.

[0059] See also Figure 5The extension line formed by the first external ejection tube 1222 extending toward the side where the second burner 130 is located intersects with the first connecting line 170, and the extension line formed by the second external ejection tube 1322 extending toward the side where the first burner 120 is located intersects with the first connecting line 170, that is, the angle between the first external ejection tube 1222 and the second external ejection tube 1322 relative to the front side 1121a will not be too small. On the contrary, if the first external ejection tube 1222 and the second external ejection tube 1322 are arranged to be parallel to the front side 1121a, the effect of reducing the space occupied by the gas stove 100 in the length direction AA is not significant enough.

[0060] See also Figure 5 In some embodiments, the entirety formed by the first inner burner 1211, the first outer burner 1212, the first inner ejector tube 1221, and the first outer ejector tube 1222 is centrally symmetrically arranged with respect to the midpoint of the first connecting line 170, as is the entirety formed by the second inner burner 1311, the second outer burner 1312, the second inner ejector tube 1321, and the second outer ejector tube 1322. That is, when transmitting gas, the velocity components of the gas in the first inner ejector tube 1221 and the second inner ejector tube 1321 in the length direction AA and the width direction BB are equal, and the velocity components of the gas in the first outer ejector tube 1222 and the second outer ejector tube 1322 in the length direction AA and the width direction BB are equal. This increases the probability that the first inner burner 1211, the first outer burner 1212, and the second inner burner 1311, and the second outer burner 1312 obtain the same amount of gas, thereby helping the first burner 120 and the second burner 130 achieve the same combustion effect. Users can enjoy the same cooking experience when using the gas stove 100.

[0061] In some embodiments, as Figure 3 as well as Figure 6 As shown, the gas stove 100 also includes a pulse igniter 150, which comprises a connected main body 151 and two ignition pins 152. The two ignition pins 152 are located adjacent to the first burner 121 and the second burner 131, respectively. The main body 151 includes a housing and a pulse generator disposed therein. It may also include a battery. The pulse generator can provide a high-voltage pulse signal to the ignition pins 152, causing them to generate sparks that ignite the gas output from the first burner 120 and the second burner 130. The ignition pins 152 are key components in the gas stove 100 for generating sparks to ignite the gas. The ignition pins 152 typically consist of a ceramic body, a needle, and a conductor. A longitudinal through-hole is defined within the ceramic body. The head of the needle protrudes from the ceramic body, while the bottom of the needle extends into the longitudinal through-hole, with the top of the conductor also extending into the through-hole. This structural design enables the ignition pins 152 to generate sparks when subjected to high-voltage current, thereby igniting the gas.

[0062] Since the distance between the second ejector tube 132 and the front side 1121a gradually increases as it points from the first burner 121 to the second burner 131, this design leaves an area empty to form a second avoidance area 110c, that is, a second avoidance area 110c is formed between the second ejector tube 132 and the rear shell 1122, and the main body 151 is installed in the second avoidance area 110c, which effectively avoids interference between the second ejector tube 132 and the main body 151. While ensuring a safe distance between the second ejector tube 132 and the main body 151, the main body 151 is allowed to be more compactly installed on the bottom shell structure 111, thereby improving the space utilization of the accommodating cavity 110a.

[0063] See also Figure 5 In some embodiments, the length of the first inner ejection tube 1221 is shorter than the length of the first outer ejection tube 1222 to avoid the second avoidance area 110c; the length of the second inner ejection tube 1321 is shorter than the length of the second outer ejection tube 1322 to avoid the first avoidance area 110b. From the perspective of layout, since the first ejection tube 122 is inclined toward the rear side 1122a, the shorter first inner ejection tube 1221 is installed on the side close to the rear side 1122a. The second avoidance area 110c is avoided to provide a larger space for assembling the main body 151; the second ejector tube 132 is tilted toward the front side 1121a, and the shorter second inner ejector tube 1321 is installed on the side close to the front side 1121a, which can avoid the first avoidance area 110b and provide a larger space for assembling the valve body assembly 140, more effectively utilizing the space in the accommodating cavity 110a, and providing a larger space for assembling the main body 151 and the valve body assembly 140.

[0064] In some embodiments, as Figure 6 As shown, the bottom shell structure 111 is formed with a first installation area 111a and a second installation area 111b along the length direction AA. The first installation area 111a is equipped with a first burner 121 and a first ejector pipe 122, and the second installation area 111b is equipped with a second burner 131 and a second ejector pipe 132. The orthographic projections of the first installation area 111a and the second installation area 111b along the width direction BB at least partially overlap, thereby reducing the occupied space in the length direction AA, making the layout of the first burner 120 and the second burner 130 more compact, which helps to adapt to kitchens and stoves of different sizes.

[0065] In some embodiments, the first mounting area 111a has a first mounting surface 1111a for mounting the first burner 121 and the first ejection tube 122, and the second mounting area 111b has a second mounting surface 1111b for mounting the second burner 131 and the second ejection tube 132. The first mounting surface 1111a and the second mounting surface 1111b are coplanar. The mounting surfaces of uniform height help to keep the appearance of the gas stove 100 neat and coordinated, thereby enhancing the overall aesthetics of the product.

[0066] Alternatively, the first mounting surface 1111a and the second mounting surface 1111b are arranged parallel to each other in the height direction of the gas stove 100, so that the layout of the first ejection pipe 122 and the second ejection pipe 132 can be staggered in the height direction to avoid interference between the first ejection pipe 122 and the second ejection pipe 132. This provides a certain degree of flexibility, and the inclination angle of the first ejection pipe 122 and the second ejection pipe 132 relative to the front side 1121a can be adjusted as needed to accommodate different sizes of the bottom shell structure 111. This makes more efficient use of the space in the accommodating cavity 110a and leaves room for other necessary components.
