Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen and bathroom appliances, and in particular to a gas stove. BACKGROUND

[0002] The thermal efficiency of a gas stove is an important parameter that reflects the energy efficiency of the gas stove. In the current use of a gas stove, the space between the burner and the cookware is almost completely open, which leads to a large amount of heat being lost to the air through heat conduction and not being effectively utilized, resulting in energy waste and reducing the thermal efficiency of the gas stove. Based on this, researchers have developed a pot support that can be enclosed around the burner. The pot support can better limit the heat conduction path while supporting the cookware, so that most of the heat is concentrated between the burner and the cookware, forming an energy concentration, which can well improve the energy efficiency of the gas stove.

[0003] However, the thermal efficiency of the gas stove is also closely related to the temperature of the primary air, which is the air used when the gas is ignited. Studies have shown that for every 10℃ increase in the temperature of the primary air, the combustion efficiency of the gas can be increased by 0.5%-1.5%. Currently, the gas stove directly uses the air around the burner as the primary air. Due to the large temperature difference between the primary air and the flame, the thermal efficiency of the gas stove is relatively low, and the traditional energy concentration pot support cannot solve the problem of low temperature of the primary air.

[0031] A second side plate portion is arranged around the burner head, and the second side plate portion is connected to one side of the first bottom plate portion close to the burner head;

[0032] A third side plate portion is arranged around the second side plate portion, and the third side plate portion is connected to one side of the first side plate portion away from the first bottom plate portion;

[0033] A second bottom plate portion is arranged around the burner head, and the second bottom plate portion is arranged opposite to the first bottom plate portion in the height direction of the burner head, the second bottom plate portion is connected between the second side plate portion and the third side plate portion, the third side plate portion extends obliquely relative to the second bottom plate portion, and the first bottom plate portion, the first side plate portion, the second side plate portion, the third side plate portion and the second bottom plate portion enclose the cavity.

[0034] The first side plate of the first energy-concentrating plate is located on the side of the first bottom plate away from the burner head, and extends at an incline relative to the first bottom plate. The second bottom plate of the second energy-concentrating plate is located below the first bottom plate in the height direction of the burner head. The third side plate of the second energy-concentrating plate is located on the side of the second bottom plate away from the burner head, and extends at an incline relative to the second bottom plate and connects with the first side plate. The second side plate connects the first bottom plate and the second bottom plate. Thus, the cavity includes a portion formed by the first bottom plate and the second bottom plate, and another portion formed by the inclined first and third side plates. The cross-sectional shape of the entire cavity perpendicular to its extension direction is similar to an L-shape, which can form thermal insulation for the space around the burner head corresponding to the height of the energy-concentrating pot support, reducing heat loss from the fire.

[0036] And / or, in the direction from the second base plate portion to the first base plate portion, the second side plate portion extends obliquely from the second base plate portion toward the burner head to guide airflow to the burner head;

[0037] And / or, the third energy-concentrating disk includes:

[0038] The third bottom plate portion is located between the first bottom plate portion and the second bottom plate portion, and the side of the third bottom plate portion near the furnace head is connected to the second side plate portion;

[0039] The fourth side plate has one side connected to the side of the third bottom plate away from the burner head, and the other side connected to the third side plate.

In the direction from the second bottom plate to the first bottom plate, the fourth side plate bends and extends from the third bottom plate in a direction away from the burner head. The first air inlet is located on the third side plate, and the first air outlet is located on the second bottom plate.

[0040] The first air inlet is arranged at a position higher than the first air outlet, so that the first air inlet is closer to the air above the energy-gathering pot support relative to the first air outlet. In this way, the heat transferred to the air and lost outside the energy-gathering pot support can be recovered, the initial temperature of the air entering the cavity is higher, the temperature of the air after heat exchange in the second sub-cavity is higher, the temperature of the primary air is as high as possible, and the thermal efficiency of the gas is improved. During use of the gas stove, the second side plate portion extends from the second bottom plate portion to the burner head in a direction in which the second bottom plate portion faces the first bottom plate portion. In this way, the second side plate portion can be used as a flow guide plate to guide the air outside the energy-gathering pot support to the burner head as secondary air for gas combustion, so that the gas is burned more fully, the combustion efficiency of the gas is improved, and the toxic and harmful gases generated by incomplete combustion of the gas are reduced.

Since the hot air heated by the fire flows upward, the first air inlet is arranged on the upper side, so that the hot air can enter the second sub-cavity, the initial temperature of the air entering the second sub-cavity is improved, and the heat transferred to the air can be better recovered.

[0041] In a possible implementation, the energy-gathering pot support further comprises:

[0042] A plurality of pot legs are arranged around the burner head and penetrate the first energy-gathering disc, the second energy-gathering disc, and the third energy-gathering disc. The pot leg has a support portion and a connecting portion. The support portion is located on the side of the first energy-gathering disc away from the second energy-gathering disc. The connecting portion is located on the side of the second energy-gathering disc away from the first energy-gathering disc. The support portion is used to support the pot.

[0043] The gas stove further comprises:

[0044] A pad disc is arranged on the first avoiding hole of the panel. The pad disc is arranged around the burner head. The pad disc is connected with the connecting portion to support the first energy-gathering disc, the second energy-gathering disc, and the third energy-gathering disc through the pot leg. In the height direction of the burner head, the pad disc is arranged below the second energy-gathering disc to form an air inlet gap between the second energy-gathering disc and the pad disc.

[0045] The gas stove realizes positioning and support of the energy-gathering pot support through cooperation of multiple pot legs and the pad plate, and constructs an air inlet gap between the pad plate and the energy-gathering pot support. During operation of the gas stove, oxygen in air in a space surrounded by the energy-gathering pot support is consumed by the fire, and at the same time, the air flows upward, which causes convection at the air inlet gap, and air can enter the space surrounded by the energy-gathering pot support through the air inlet gap.

[0047] a main body part provided with a second avoiding hole and an air duct hole, the burner passes through the second avoiding hole and extends into the energy-gathering pot support, the fan assembly is connected to the first air outlet through the air duct hole, and the main body part is further provided with multiple installation grooves, and a part of the multiple connection parts is correspondingly embedded in the installation grooves;

[0048] a bearing part arranged around the main body part, in the height direction of the burner, a surface of the bearing part towards the burner is below a surface of the main body part towards the burner, and the bearing part is used for bearing the connection parts.

[0049] By arranging the installation grooves in the main body part, the connection parts are limited by the installation grooves, so that the position of the energy-gathering pot support is kept stable. Meanwhile, the connection parts are borne by the bearing part, and since the energy-gathering pot support is only fixed by the embedded connection parts of the pot legs and the installation grooves, the energy-gathering pot support and the pad plate are convenient to disassemble and assemble, and if the pot support needs to be replaced, the energy-gathering pot support can be directly taken away from the pad plate, and then other pot support is replaced.

[0050] In a possible implementation, the first energy-gathering disc comprises:

[0051] a first bottom plate part arranged around the outer periphery of the burner;

[0052] a first side plate part arranged around the outer periphery of the first bottom plate part, in the radial direction of the burner, a side of the first bottom plate part away from the first side plate part is further bent and extended along a direction of the first energy-gathering disc pointing to the second energy-gathering disc, so as to form a liquid collecting groove at the connection between the first bottom plate part and the first side plate part;

[0053] wherein the radial direction of the burner is perpendicular to the height direction of the burner.

[0054] By forming the first energy collecting disc into a liquid collecting groove on the first bottom plate part, in the process of using the gas stove to heat the pot for cooking, if the liquid in the pot overflows, the liquid collecting groove can collect and temporarily store the overflowing liquid, prevent the liquid from flowing to the burner after overflowing from the pot, so as to avoid the liquid affecting or even extinguishing the fire, and thus the gas stove can continuously and efficiently heat.

[0055] In a possible implementation, the first air inlet and the first air outlet are located on opposite sides of the burner in the radial direction.

[0056] The radial direction of the burner is perpendicular to the height direction of the burner.

[0057] The first air inlet and the second air inlet can be taken as the endpoints to define two cavity segments with the same length, so that the negative pressure formed by the fan assembly in the cavity is distributed symmetrically about the line connecting the first air inlet and the first air outlet. In this way, when the air enters the cavity from the first air inlet, the air is divided into two air flows, which flow to the first air outlet from the two sides of the line connecting the first air inlet and the first air outlet, so as to make the air entering the cavity enter the ejector pipe as soon as possible while ensuring that the air exchanges heat with the energy collecting pot support on a long enough flow path.

[0058] Compared with the prior art, the application has the following beneficial effects:

[0059] The gas stove of the application, the energy collecting pot support is arranged around the burner, and the energy collecting pot support includes a first energy collecting disc and a second energy collecting disc configured to form a closed cavity, and the second energy collecting disc is provided with a first air inlet and a first air outlet communicating with the cavity. At the same time, the ejector pipe connected with the burner is also connected with the energy collecting pot support through the fan assembly, so that the inside of the cavity and the inside of the ejector pipe are connected with each other. In this way, during the use of the gas stove, the fan assembly can introduce the air outside the energy collecting pot support into the cavity and form an air flow, the air flow exchanges heat with the inner surface of the energy collecting pot support by convection, transfers the heat conducted to the energy collecting pot support to the air flow to increase the temperature of the air, and then the air flow enters the ejector pipe through the fan assembly, and the preheated air flow can be used as primary air to mix and burn with gas. That is, the gas stove of the application can recover the heat of the energy collecting pot support outside the gas stove to preheat the primary air, increase the temperature of the primary air, and then deliver the primary air to the ejector pipe inside the gas stove to mix and burn with gas, so that the gas can be more fully burned, thereby improving the combustion efficiency of the gas stove and reducing the toxic and harmful gases such as CO and NO generated by incomplete combustion of gas.

[0078] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0079] In the present application, the terms "upper", "rear", "inner", "outer", "middle" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0080] In addition, the above-mentioned partial terms can be used to represent other meanings in addition to the orientation or positional relationship, for example, the term "upper" can also be used to represent a certain dependent relationship or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

[0081] In addition, the terms "set", "connected" should be broadly understood. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0082] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0083] Thermal efficiency is one of the most important indicators of gas stoves. The higher the thermal efficiency, the higher the proportion of heat effectively utilized in the heat generated during the use of the gas stove. By improving the thermal efficiency of the gas stove, the same heating effect can be achieved with less gas, which helps to save gas and reduce energy waste. The main ways to improve thermal efficiency are to reduce heat loss, heat recovery and reuse, and improve the combustion efficiency of gas. In the related art, a concentrated energy pot support is generally used to concentrate heat. During use, the space between the concentrated energy pot support and the pot is relatively low in openness, and most of the heat is confined in this space, with less loss. Heat recovery and reuse usually collect high-temperature flue gas generated by the flame through a pipe and use the high-temperature flue gas to heat water. Improving the combustion efficiency of gas generally provides sufficient air for gas combustion to prevent insufficient air from causing incomplete combustion during the combustion process.

[0084] Because the space between the energy-gathering pot support and the pot is relatively low in openness, the air around the flame is relatively less, and the gas is prone to incomplete combustion. Therefore, the inventors attempt to supplement the burner with sufficient secondary air to improve the combustion efficiency of the gas, but this requires increasing the openness of the energy-gathering pot support, thereby increasing the heat lost to the air through heat transfer, reducing the energy-gathering effect. In addition, during the operation of the gas stove, part of the heat is transferred to the energy-gathering pot support, and this part of the heat is difficult to recover and is basically wasted by being transferred to the air through heat transfer. In addition, the main factor affecting the combustion efficiency of the gas is whether the primary air is sufficient, and supplementing the secondary air does not have a significant effect on improving the combustion efficiency.

[0085] Based on the above circumstances, the embodiments of the present application provide a gas stove, wherein the energy-gathering pot support is arranged around the burner, and the energy-gathering pot support comprises a first energy-gathering disc and a second energy-gathering disc which are configured to form a closed cavity, and the second energy-gathering disc is provided with a first air inlet and a first air outlet which communicate with the cavity. At the same time, the injection pipe connected with the burner is also connected with the energy-gathering pot support through a fan assembly, so that the inside of the cavity and the inside of the injection pipe are in communication with each other. In this way, during the use of the gas stove, the fan assembly can introduce the air outside the energy-gathering pot support into the cavity and form an air flow, the air flow exchanges heat with the inner surface of the energy-gathering pot support by convection, transfers the heat conducted to the energy-gathering pot support to the air flow, and increases the temperature of the air, and then the air flow enters the injection pipe through the fan assembly, and the preheated air flow can be mixed with the gas for combustion as primary air. That is, the gas stove of the present application can recover the heat of the energy-gathering pot support outside the gas stove to preheat the primary air, and after increasing the temperature of the primary air, the primary air is delivered to the injection pipe inside the gas stove to mix with the gas for combustion, so that the gas can be more fully combusted, thereby improving the combustion efficiency of the gas stove and reducing the toxic and harmful gases such as CO and NO generated due to incomplete combustion of the gas.

[0086] The technical solutions of the present application will be further described below in conjunction with the embodiments and the accompanying drawings.

[0088] In some embodiments, the gas stove 1 comprises a housing 11 having a mounting cavity 11a which can be used to accommodate some devices of the gas stove 1, such as a control panel, a display panel, a part of gas pipe, etc.

[0089] For example, the housing 11 can be a square shell having a bottom 111 and a wall 112 arranged along the edge of the bottom 111, and the bottom 111 and the wall 112 enclose the above-mentioned mounting cavity 11a.

[0090] In some embodiments, the gas stove 1 further comprises a panel 12 which is arranged on the housing 11, and the panel 12 is provided with a first avoiding hole 12a which is in communication with the mounting cavity 11a. The panel 12 can be a planar member which is arranged on the housing 11 to cover the mounting cavity 11a, and the first avoiding hole 12a can expose part of the mounting cavity 11a so that some devices located in the mounting cavity 11a can be exposed to the outside of the gas stove 1 through the first avoiding hole 12a.

[0091] It can be understood that the panel 12 can be provided with knobs or buttons for adjusting the size of the flame and / or changing the burning mode of the flame, and buttons for ignition, etc.

[0092] The housing 11 and the panel 12 can be configured to form a box structure which is generally hexahedral in shape, and has a width direction X, a depth direction Y and a height direction Z which are perpendicular to each other in pairs.

[0093] In some other embodiments, the housing 11 and the panel 12 can be configured as an integrated structure, in which the wall 112 of the housing 11 is connected to the panel 12 and encloses the above-mentioned mounting cavity 11a with the panel 12, and the bottom 111 can be completely removed or partially removed as long as it can ensure that other devices of the gas stove 1 can be smoothly assembled into the mounting cavity 11a.

[0094] In some embodiments, the gas stove 1 further comprises a burner assembly 13 which is arranged on the housing 11, and part of the burner assembly 13 is located in the mounting cavity 11a, and the other part is exposed to the outside of the mounting cavity 11a through the first avoiding hole 12a. In the working process of the gas stove 1, the flame is located at the burner assembly 13, and the pot can be placed on the burner assembly 13 so as to be heated by the flame.

[0095] In some embodiments, the burner assembly 13 comprises a burner 131 which is fixed to the housing 11, and part of the burner 131 is located in the mounting cavity 11a, and the other part is exposed to the outside of the mounting cavity 11a through the first avoiding hole 12a. It can be understood that the burner 131 is fixedly connected to the bottom 111 of the housing 11 to fix the position of the burner 131.

[0096] For example, the burner head 131 is configured in a circular shape. The circular shape of the burner head 131 can make the flame more evenly distributed, and thus the pot can be heated more evenly, avoiding the pot from being burnt due to excessive heat concentration.

[0097] In some embodiments, the burner head assembly 13 further comprises an injector pipe 132 located in the installation cavity 11a, one end of the injector pipe 132 is connected with the burner head 131, and the injector pipe 132 is used to connect the burner head 131 and an external gas source (not shown) so that the gas can reach the burner head 131 through the injector pipe 132, and thus the gas can be combusted at the position of the burner head 131. It should be noted that the injector pipe 132 is located in the installation cavity 11a.

[0098] In some embodiments, the gas stove 1 further comprises a fan assembly 133, one end of the fan assembly 133 is located in the installation cavity 11a to connect the other end of the injector pipe 132, and the other end of the fan assembly 133 extends to the outside of the installation cavity 11a.

[0099] In some embodiments, the burner head assembly 13 further comprises a heat-accumulating pot support 134 located outside the installation cavity 11a, and the heat-accumulating pot support 134 is arranged around the burner head 131. During use of the gas stove 1, the heat-accumulating pot support 134 is used to support the pot. The heat-accumulating pot support 134 surrounds a cavity 134a arranged around the burner head 131. By arranging the cavity 134a, the heat transfer between the inner side wall and the outer side wall of the heat-accumulating pot support 134 can be reduced, and thus the heat loss can be reduced. It can be understood that the inner side wall of the heat-accumulating pot support 134 refers to the side wall on the side of the heat-accumulating pot support 134 close to the burner head 131, and the outer side wall refers to the side wall on the side of the heat-accumulating pot support 134 away from the burner head 131.

[0100] In some embodiments, the energy-gathering pot support 134 is provided with a first air inlet 134b and a first air outlet 134c which are in communication with the cavity 134a. The first air inlet 134b is configured to enable air to be preheated to enter the cavity 134a, and the first air outlet 134c is in communication with the other end of the fan assembly 133 and is configured to enable the preheated air to flow into the fan assembly 133. In this way, during the operation of the gas stove 1, the air outside the energy-gathering pot support 134 can be introduced into the cavity 134a through the first air inlet 134b by means of the fan assembly 133, and the air flow entering the cavity 134a can exchange heat with the energy-gathering pot support 134 in a countercurrent manner in the cavity 134a, so that the heat of the flame transferred to the energy-gathering pot support 134 by heat conduction is transferred to the air flow, the air in the cavity 134a is preheated, and the preheated air can enter the injection pipe 132 through the first air outlet 134c again by means of the fan assembly 133. The preheated air mixes with the gas entering the injection pipe 132 and then burns, which can improve the combustion efficiency of the gas and reduce the generation of toxic and harmful gases such as CO and NO due to insufficient combustion of the gas.

[0101] It should be noted that the height direction of the burner head 131 is the same as the height direction Z of the cabinet structure, and hereinafter the height direction of the burner head 131 is represented by the height direction Z of the cabinet.

[0102] Again referring to Figure 4 In some embodiments, the first air inlet 134b and the first air outlet 134c are arranged on opposite sides in the radial direction of the burner head 131, and the cavity 134a can be defined as two cavity segments with the same extension length with the first air inlet 134b and the first air outlet 134c as the end points, and the negative pressure formed by the fan assembly 133 in the cavity 134a can be distributed symmetrically about the line connecting the first air inlet 134b and the first air outlet 134c. In this way, when the air enters the cavity 134a from the first air inlet 134b, the air is divided into two air flows which flow from the two sides of the line connecting the first air inlet 134b and the first air outlet 134c to the first air outlet 134c, and the air flow can contact the inner wall surface of the energy-gathering pot support 134 and absorb the heat of the energy-gathering pot support 134 during the flow of the air along the extension path of the cavity 134a, and then flow out of the cavity 134a from the first air outlet 134c. The radial direction of the burner head 131 is perpendicular to the height direction Z of the cabinet structure. Among them, Figure 5 The dashed arrows in the figure are used to illustrate the flow path of the gas.

[0103] Of course, the first air inlet 134b and the first air outlet 134c can also not be arranged on opposite sides in the radial direction of the burner head 131, i.e. the cavity 134a can be defined as two cavity sections with different extension lengths with the first air inlet 134b and the first air outlet 134c as end points. When the fan assembly 133 is in operation, the air flow can flow more along the cavity section with shorter extension length and out of the cavity 134a from the first air outlet 134c.

[0104] Please refer to Figures 5 to 7 , Figure 5 is a flow diagram of air flow in the cavity of the energy-gathering pot support, Figure 6 is a layout diagram of the fan assembly in the embodiment of the present application, Figure 7 is a structure diagram of the fan assembly in the embodiment of the present application.

[0105] In some embodiments, the fan assembly 133 comprises a duct member 1331 and a fan 1332, the fan 1332 is fixedly connected to the duct member 1331, and the duct member 1331 is connected to the first air outlet 134c and the ejector pipe 132. When the fan 1332 is in operation, a negative pressure is formed in the duct member 1331, so that the air outside the energy-gathering pot support 134 can enter the cavity 134a from the first air inlet 134b, then enter the duct member 1331 from the first air outlet 134c, and finally enter the ejector pipe 132.

[0106] In some embodiments, in the height direction Z of the box structure, the duct member 1331 is arranged below the second energy-gathering disc 1343, one end of the duct member 1331 is located outside the mounting cavity 11a and connected to the first air outlet 134c, and the other end of the duct member 1331 is located in the mounting cavity 11a to be connected to the ejector pipe 132.

[0107] It should be noted that, since the ejector pipe 132 has a certain extension length, the end of the ejector pipe 132 connected to the duct member 1331 is usually not directly below the first air outlet 134c, so the duct member 1331 needs to be bent at least once to connect the first air outlet 134c and the ejector pipe 132. In some embodiments, in order to reduce the air resistance of the air flow in the duct member 1331, the bent part of the duct member 1331 can be arranged as an arc-shaped bend.

[0108] It can be understood that the duct member 1331, the fan 1332 and the ejector pipe 132 jointly constitute a closed air duct, so that the air in the cavity 134a can flow out of the cavity 134a from the first air outlet 134c and enter the ejector pipe 132 through the duct member 1331 under the action of the fan 1332.

[0109] In some embodiments, the air duct 1331 comprises a first sub-air duct 13311 and a second sub-air duct 13312. The first sub-air duct 13311 has opposite first and second ends 13311a and 13311b. The first end 13311a is connected to the first air outlet 134c, and the second end 13311b is connected to one end of the fan 1332. The second sub-air duct 13312 has opposite third and fourth ends 13312a and 13312b. The third end 13312a is connected to the other end of the fan 1332, and the fourth end 13312b is connected to the ejector pipe 132. In this way, the first sub-air duct 13311, the fan 1332, the second sub-air duct 13312, and the ejector pipe together form a closed air duct.

[0110] In some embodiments, the first sub-air duct 13311 comprises a first straight pipe segment 133111, a first arc-shaped bending portion 133112, and a second straight pipe segment 133113 connected in sequence. The first end 13311a of the first straight pipe segment 133111 is located at an end thereof away from the first arc-shaped bending portion 133112, and the second end 13311b of the second straight pipe segment 133113 is located at an end thereof away from the first arc-shaped bending portion 133112. The first straight pipe segment 133111 extends along the height direction Z of the cabinet structure. An end thereof away from the first air outlet 134c is connected to the first arc-shaped bending portion 133112. The first arc-shaped bending portion 133112 extends along a direction perpendicular to the height direction Z after being bent, and is connected to the second straight pipe segment 133113. The second straight pipe segment 133113 extends along a direction perpendicular to the height direction Z. Similarly, the second sub-air duct 13312 is also provided with an arc-shaped bending portion 133111 between the third end 13312a and the fourth end 13312b. Specifically, the second sub-air duct 13312 comprises a second arc-shaped bending portion 133121 and a third straight pipe segment 133122 connected in sequence. The third end 13312a of the second arc-shaped bending portion 133121 is located at an end thereof away from the second straight pipe segment 133122, and the fourth end 13312b of the second straight pipe segment 133122 is located at an end thereof away from the second arc-shaped bending portion 133121. The second arc-shaped bending portion 133121 is connected to the fan 1332 and is bent along the width direction X or the depth direction Y. The third straight pipe segment 133122 is connected between the second arc-shaped bending portion 133121 and the ejector pipe 132.

[0111] It can be understood that the fan 1332 is connected to the second straight pipe segment 133113 and the third straight pipe segment 133122 through the volute thereof.

[0112] Please refer to Figures 8 to 9 , Figure 8 is a structural schematic diagram of a concentrated pot support in the embodiments of the present application, Figure 9 is an assembly schematic diagram of a pot foot and a pad in the embodiments of the present application, Figure 10is Figure 1 a side view of the gas stove, Figure 11 is Figure 9 an enlarged view of the B region in the middle.

[0113] In some embodiments, the energy-gathering pot support 134 further comprises a plurality of energy-gathering discs and a plurality of pot feet 1341, the plurality of energy-gathering discs are sequentially connected along the height direction Z of the box structure to form the above-mentioned cavity 134a. The plurality of pot feet 1341 penetrates through the plurality of energy-gathering discs, and the opposite ends of the pot feet 1341 are located on the opposite sides of the plurality of energy-gathering discs in the height direction Z of the box structure. The plurality of pot feet 1341 is arranged around the burner head 131. When the gas stove 1 is used to heat the pot, the pot feet 1341 are used to support the pot.

[0114] It can be understood that in order to make the pot feet 1341 penetrate through the plurality of energy-gathering discs, each energy-gathering disc is provided with a through hole for the pot feet 1341 to penetrate through. The pot feet 1341 and the openings of the plurality of energy-gathering discs can be in interference fit or can be fixed by welding. In this way, it can not only ensure that the pot feet 1341 and the energy-gathering discs have sufficient fastening effect, but also make the cavity 134a formed by the energy-gathering discs have sufficient airtightness at the openings, so as to avoid air leakage of the cavity 134a at positions other than the first air inlet 134b and the first air outlet 134c, thereby preventing heat loss.

[0115] In some embodiments, the pot feet 1341 have a supporting part 13411 and a connecting part 13412, the supporting part 13411 is located on the side of the first energy-gathering disc 1342 away from the second energy-gathering disc 1343, and the connecting part 13412 is located on the side of the second energy-gathering disc 1343 away from the first energy-gathering disc 1342, and the supporting part 13411 is used to support the pot.

[0116] In some embodiments, the gas stove 1 further comprises a pad disc 14, the pad disc 14 is arranged on the first avoiding hole 12a of the panel 12, the pad disc 14 is arranged around the burner head 131, and the pad disc 14 is connected with the connecting part 13412 of the pot feet 1341. In this way, the pad disc 14 can support the plurality of energy-gathering discs through the pot feet 1341. The pad disc 14 is provided with a second avoiding hole 14a which is in communication with the first avoiding hole 12a, and the outline of the second avoiding hole 14a is similar to the outer outline of the burner head 131. The distance between the edge of the pad disc 14 surrounding the second avoiding hole 14a and the burner head 131 is small, for example, between 5mm-10mm, and the burner head 131 penetrates through the second avoiding hole 14a to expose to the outside of the mounting cavity 11a. In this way, the first avoiding hole 12a can be covered by the pad disc 14, and since the distance between the pad disc 14 and the burner head 131 is small, foreign matter can be prevented from entering the mounting cavity 11a from the first avoiding hole 12a.

[0117] In some embodiments, the pad 14 is provided with an air duct opening 14b, the first end 13311a of the first sub-air duct member 13311 is connected with the air duct opening 14b, and the air duct opening 14b is further connected with the first air outlet 134c. That is, the first sub-air duct member 13311 is connected with the first air outlet 134c through the air duct opening 14b.

[0118] Optionally, the energy-gathering pot support 134 can be provided with an air nozzle connected with the air duct opening 14b, and the air nozzle has the first air outlet 134c described above. Alternatively, the pad 14 is provided with an air nozzle, the air nozzle has the air duct opening 14b, and the air duct opening 14b of the air nozzle is connected with the first air outlet 134c.

[0119] In some embodiments, along the height direction Z of the box structure, the pad 14 and the energy-gathering pot support 134 are arranged at intervals to form an air inlet gap 14c between the energy-gathering pot support 134 and the pad 14. In this way, during the combustion of the fire, external air can enter the space surrounded by the energy-gathering pot support 134 from the air inlet gap 14c through natural convection, and these air can serve as secondary air for the combustion of the gas, so that the gas can be fully combusted, the combustion efficiency of the gas is improved, and the toxic and harmful gases generated due to insufficient combustion of the gas are reduced.

[0120] In some embodiments, the pad 14 includes a main body portion 141 and a bearing portion 142, the bearing portion 142 is arranged around the main body portion 141, the bearing portion 142 is overlapped on the edge of the panel 12 surrounding the first avoiding hole 12a, and the bearing portion 142 also receives the connecting portion 13412 described above. It can be understood that the main body portion 141 is provided with the second avoiding hole 14a described above, and the burner 131 passes through the main body portion 141. Moreover, when the air duct opening 14b is arranged on the pad 14, the air duct opening 14b is arranged on the main body portion 141.

[0121] In some embodiments, along the height direction Z of the box structure, the surface of the bearing portion 142 facing the energy-gathering pot support 134 is located below the surface of the main body portion 141 facing the energy-gathering pot support 134. That is, the main body portion 141 and the bearing portion 142 form a stepped structure, and the main body portion 141 is provided with a plurality of mounting grooves 141a, and the connecting portion 13412 is correspondingly embedded in the mounting grooves 141a, the connecting portion 13412 is limited by the mounting grooves 141a, so that the position of the energy-gathering pot support 134 is kept stable. At the same time, since the energy-gathering pot support 134 is only fixed by the embedding of the connecting portion 13412 of the pot foot 1341 in the mounting grooves 141a, if it is necessary to replace the pot support according to the needs, the energy-gathering pot support 134 can be directly removed from the pad 14, and then other pot support can be replaced.

[0122] In some scenarios, the pad 14 is a ceramic / enamel structure, and the pot leg 1341 is usually a heat-resistant and high-hardness metal. If the pot leg 1341 directly contacts the pad 14, the pad 14 can be abraded by the pot leg 1341. Adaptively, the connecting portion 13412 of the pot leg 1341 can be provided with a scratch-proof structure 13413 for preventing the connecting portion 13412 from directly contacting the inner wall of the mounting groove 141a, so as to avoid the connecting portion 13412 scratching the pad 14.

[0123] Optionally, the scratch-proof structure 13413 can be made of a material with low hardness, such as plastic. It can also be made of a material with elasticity, such as rubber, silicone, plastic, etc. The scratch-proof structure 13413 can be fixed on the connecting portion 13412 by bonding, screwing, etc. When the connecting portion 13412 is embedded in the mounting groove 141a, the connecting portion 13412 contacts the inner wall of the mounting groove 141a through the scratch-proof structure 13413.

[0124] Please refer to Figures 12 to 15 , Figure 12 is a structure exploded schematic view of the energy-gathering pot support with a third energy-gathering disc in the embodiment of the present application, Figure 13 is a sectional view of the gas stove with a third energy-gathering disc along the direction of A-A' in Figure 1 , Figure 14 is an enlarged schematic view of the C region in Figure 13 , Figure 15 is an enlarged schematic view of the D region in Figure 13 .

[0125] In some embodiments, the energy-gathering pot support 134 includes a first energy-gathering disc 1342 and a second energy-gathering disc 1343, both of which are located outside the mounting cavity 11a. In the height direction of the burner head 131, the second energy-gathering disc 1343 is connected to the lower side of the first energy-gathering disc 1342, so that the first energy-gathering disc 1342 and the second energy-gathering disc 1343 jointly enclose the above-mentioned cavity 134a. The first gas inlet 134b and the first gas outlet 134c are arranged on the second energy-gathering disc 1343.

[0126] In some embodiments, the first energy concentrating disc 1342 comprises a first bottom plate portion 13421 and a first side plate portion 13422, the first bottom plate portion 13421 is arranged around the outer periphery of the burner 131, the first side plate portion 13422 is arranged around the outer periphery of the first bottom plate portion 13421, and the first side plate portion 13422 also extends obliquely relative to the first bottom plate portion 13421. For example, the first bottom plate portion 13421 is substantially perpendicular to the height direction Z of the box structure, has opposite inner and outer edges, the inner edge of the first bottom plate portion 13421 surrounds a through hole for exposing the burner 131, and the first side plate portion 13422 is connected to the outer edge of the first bottom plate portion 13421 and is arranged obliquely relative to the first bottom plate portion 13421. Specifically, the first side plate portion 13422 also extends obliquely upward along the height direction Z of the box structure in the direction in which the inner edge of the first bottom plate portion 13421 points to the outer edge. That is, the first bottom plate portion 13421 and the first side plate portion 13422 together form a groove-shaped structure that can confine most of the heat of the burner in the space formed thereby.

[0127] For example, the first bottom plate portion 13421 can be a circular ring, the first side plate portion 13422 is a ring structure, the edge of the first side plate portion 13422 connected to the outer edge of the first bottom plate portion 13421 is also circular, and the edge (i.e. the outer contour) of the first side plate portion 13422 away from the first bottom plate portion 13421 can be circular, square, rounded square, etc. In some embodiments, the outer contour of the first side plate portion 13422 is rounded square, when the side length of the square is the same as the diameter of the circle, the area of the rounded square is larger than that of the circle, so that the heat of the burner can be uniformly confined in a larger area, that is, a larger area of the bottom of the pot can be heated to improve the uniformity of heating the pot and avoid damage to the pot caused by excessive concentration of heat. At the same time, the corners of the square are set to be rounded, which can not only reduce the sharpness of the corners to avoid users being cut by the corners of the energy concentrating pot support 134 during use of the gas stove 1, but also make the appearance of the energy concentrating pot support 134 more beautiful through the rounded design.

[0128] In some embodiments, the part of the first bottom plate portion 13421 close to the burner 131 can be arranged to extend obliquely upward along the height direction Z of the box structure to form a liquid collecting groove 1342a at the joint of the first bottom plate portion 13421 and the first side plate portion 13422. In this way, during use of the gas stove 1, if the liquid in the pot overflows, the liquid collecting groove 1342a can collect the overflowing liquid to prevent the liquid from flowing to the burner 131 and to prevent the overflowing liquid from affecting or extinguishing the fire.

[0129] In some embodiments, the included angle between the first bottom plate portion 13421 and the first side plate portion 13422 is a, and the relationship 130°≤a≤160° is satisfied. For example, a can be 130°, 135°, 140°, 145°, 150°, 155°, 160° or other angles within the range. Within the range, the first energy-gathering disc 1342 can better limit the heat distribution space, reduce heat loss, while keeping the heat distribution area within a reasonable range, so that the heat of the flame can uniformly heat the pot on the energy-gathering pot support 134, avoiding excessive concentration of heat to damage the pot. When a<130°, the heat distribution area of the burner 131 is small, the heat is too concentrated, the heating of the pot is not uniform enough, and the pot is easily damaged. When a>160°, the heat distribution area is large, the heat is excessively dispersed, the heating efficiency of the pot is reduced, and heat loss is easily caused, thereby reducing the thermal efficiency of the gas stove 1.

[0130] In some embodiments, the second energy-gathering disc 1343 includes a second side plate portion 13431, a third side plate portion 13432 and a second bottom plate portion 13433. The second side plate portion 13431 surrounds the burner 131, and the second side plate portion 13431 is connected to one side of the first bottom plate portion 13421 close to the burner 131, that is, the second side plate portion 13431 is connected to the inner edge of the first bottom plate portion 13421. The third side plate portion 13432 surrounds the second side plate portion 13431 and is connected to one side of the first side plate portion 13422 away from the first bottom plate portion 13421, and the second side plate portion 13431 and the third side plate portion 13432 are oppositely arranged. The second bottom plate portion 13433 surrounds the burner 131, and in the height direction Z of the box structure, the second bottom plate portion 13433 is oppositely arranged with the first bottom plate portion 13421 and located below the first bottom plate portion 13421, the second bottom plate portion 13433 is connected between the second side plate portion 13431 and the third side plate portion 13432, and the third side plate portion 13432 also extends obliquely relative to the second bottom plate portion 13433. It can be understood that the first bottom plate portion 13421, the first side plate portion 13422, the second side plate portion 13431, the third side plate portion 13432 and the second bottom plate portion 13433 form a cavity 134a. The first bottom plate portion 13421 and the second bottom plate portion 13433 are substantially arranged in parallel.

[0131] Specifically, the third side plate portion 13432 is inclined relative to the second bottom plate portion 13433, such that the orthographic projection of the second bottom plate portion 13433 on the height direction Z of the box structure is located within the orthographic projection range of the first energy concentrating disc 1342 on the height direction Z of the box structure. That is, the area of the outer contour of the lower end of the energy pot support 134 on the height direction Z of the box structure is less than the area of the outer contour of the upper end thereof. In this way, the energy concentrating effect of the energy pot support 134 on the fire can be ensured, while the volume of the energy pot support 134 can be appropriately reduced, and the space occupied thereby can be reduced.

[0132] In some embodiments, the second side plate portion 13431 of the second energy concentrating disc 1343 is arranged to be inclined relative to the second bottom plate portion 13433 to guide the air flow to the burner head 131. Specifically, in the direction in which the second bottom plate portion 13433 points to the first bottom plate portion 13421, the second side plate portion 13431 extends to be inclined towards the burner head 131. In this way, when the air enters the air inlet gap 14c, the inclined second side plate portion 13431 can guide the air to the position where the burner head 131 is located, so that the secondary air can accurately reach the fire to supplement the air required for the combustion of the gas.

[0133] In some embodiments, the second side plate portion 13431 and the second bottom plate portion 13433 are connected by an arc-shaped plate portion 13434, and the arc-shaped plate portion 13434 protrudes towards the side of the burner head. In this way, when the air enters the air inlet gap 14c under natural convection, the air flow can flow close to the surface of the arc-shaped plate portion 13434 and the second side plate portion 13431 at the arc-shaped plate portion 13434 due to the wall attachment effect, and the air flow can flow along the second side plate portion 13431 to the burner head 131 due to the inclined arrangement of the second side plate portion 13431. At the same time, the connection of the second side plate portion 13431 and the second bottom plate portion 13433 by the arc-shaped plate portion 13434 can reduce the wind resistance of the air flow in the air inlet gap 14c.

[0134] In some embodiments, the top end of the second side plate portion 13431 is located below the burner head 131 in the height direction Z of the box structure. In this way, the secondary air can accurately reach the fire under the action of natural convection and the second side plate portion 13431, so that the gas can be fully combusted. At the same time, the heat of the fire can be prevented from being transmitted from the air inlet gap 14c to the outside of the energy pot support 134, so that heat loss can be prevented.

[0135] In some embodiments, the first air inlet 134b is arranged at an edge of the third side plate portion 13432 away from the second bottom plate portion 13433, and the first air outlet 134c is arranged at the second bottom plate portion 13433. In other words, in the height direction Z of the box structure, the first air inlet 134b is arranged higher than the first air outlet 134c. It can be understood that, in the working process of the gas stove 1, the air heated by the flame of the heated pot will flow upwards, and by arranging the first air inlet 134b at a higher position, air with a higher temperature can be more easily obtained, i.e., it helps to increase the initial temperature of the air entering the cavity 134a. In addition, since the injection pipe 132 is located below the second energy collecting disc 1343 and in the mounting cavity 11a, by arranging the first air outlet 134c at the second bottom plate portion 13433, the distance between the first air outlet 134c and the injection pipe 132 can be reduced, which helps to reduce the extension length of the air duct piece 1331, simplify the structure of the gas stove 1, and reduce the manufacturing cost.

[0136] In some embodiments, the third side plate portion 13432 includes a first sub-side plate portion 134321 and a second sub-side plate portion 134322, the first sub-side plate portion 134321 is connected with the second bottom plate portion 13433, and the second sub-side plate portion 134322 is connected to a side of the first sub-side plate portion 134321 away from the second bottom plate portion 13433. The included angle β between the first sub-side plate portion 134321 and the second bottom plate portion 13433 is greater than the included angle γ between the second sub-side plate portion 134322 and the second bottom plate portion 13433. That is, in the height direction Z of the box structure, the lower half of the energy collecting pot support 134 has a larger inclination angle, which can reduce the bottom area of the energy collecting pot support 134, thereby reducing the volume of the lower half of the energy collecting pot support 134. At the same time, the inclination angle of the upper half of the energy collecting pot support 134 is reduced, so that the upper half of the energy collecting pot support 134 is relatively gathered to the lower half, avoiding that the outer wall of the energy collecting pot support 134 has a too large inclination angle, which causes the volume of the upper half of the energy collecting pot support 134 to be too large as the height increases, and also ensuring the effective limitation of the energy collecting pot support 134 on the heat distribution of the fire.

[0137] In some embodiments, the included angle β between the first sub-side plate portion 134321 and the second bottom plate portion 13433 satisfies the relationship: 120°≤β≤140°, for example, β can be 120°, 125°, 130°, 135°, 140° or other angle values. Within this range, the volume of the bottom of the energy-gathering pot support 134 can be effectively reduced, while the energy-gathering effect is also avoided due to the excessive volume of the bottom of the energy-gathering pot support 134. When β<120°, if the lower half of the energy-gathering pot support 134 has a small volume, the upper half is also small, which cannot disperse the heat of the fire in a reasonable area, resulting in heat concentration, poor heating effect on the pot, and easy damage to the pot. If the lower half of the energy-gathering pot support 134 has a large volume, the upper half also has a large volume, which cannot effectively limit heat loss, and also leads to an excessively large overall volume of the energy-gathering pot support 134. When β>140°, the overall volume of the energy-gathering pot support 134 is large, and the gathering effect of the energy-gathering pot support 134 is reduced, which cannot effectively prevent heat loss.

[0138] In some embodiments, the included angle γ between the second sub-side plate portion 134322 and the second bottom plate portion 13433 satisfies the relationship: 90°≤γ≤100°, for example, γ can be 90°, 92°, 94°, 96°, 98°, 100° or other angle values. Within this range, the upper half of the energy-gathering pot support 134 can be better gathered, the overall volume of the energy-gathering pot support 134 can be reduced, and the restraining effect of the energy-gathering pot support 134 on the heat of the fire can be improved. When γ<90°, the area outlined by the top of the energy-gathering pot support 134 is small, which makes the heat of the fire too concentrated, resulting in uneven heating of the gas stove 1 on the pot, and easy damage to the pot. When γ>100°, the area outlined by the top of the energy-gathering pot support 134 is too large, which will cause the heat of the fire to be excessively dispersed, reduce the heating efficiency of the fire on the pot, and thus reduce the thermal efficiency of the gas stove 1.

[0139] In some embodiments, the energy-gathering pot support 134 further comprises a third energy-gathering disc 1344, the third energy-gathering disc 1344 is located in the cavity 134a, the third energy-gathering disc 1344 is arranged around the burner head 131 and is fixedly connected to the second energy-gathering disc 1343. The third energy-gathering disc 1344 divides the cavity 134a into a first sub-cavity 134a1 and a second sub-cavity 134a2, and the first sub-cavity 134a1 and the second sub-cavity 134a2 are arranged one after another along the height direction Z of the box structure. In this way, a double-layer cavity can be formed inside the energy-gathering pot support 134, which can better insulate by air in the double-layer cavity, improve the energy-gathering effect of the energy-gathering pot support 134, and reduce heat loss.

[0140] In some embodiments, the first air inlet 134b and the first air outlet 134c do not communicate with the first sub-cavity 134a1, and the first air inlet 134b and the first air outlet 134c communicate with the second sub-cavity 134a2. Air enters the second sub-cavity 134a2 through the first air inlet 134b and then flows out of the second sub-cavity 134a2 through the first air outlet 134c. In this way, the first sub-cavity 134a1 is a completely enclosed cavity, and the air inside the first sub-cavity 134a1 does not exchange heat with the air outside the energy-concentrating pot support 134, thereby achieving good heat insulation and reducing heat loss, so that more heat of the gas stove 1 is used for heating the pot.

[0141] In some embodiments, the first sub-cavity 134a1 can be provided with heat insulation materials, such as a heat insulation film provided on the inner wall of the energy-concentrating pot support 134 surrounding the first sub-cavity 134a1, or the first sub-cavity 134a1 is filled with heat insulation materials. In this way, the heat insulation effect of the energy-concentrating pot support 134 can be further improved, heat loss can be reduced, and the thermal efficiency of the gas stove 1 can be improved.

[0142] In some embodiments, the volume of the first sub-cavity 134a1 is V1, the volume of the second sub-cavity 134a2 is V2, and the volume V1 of the first sub-cavity 134a1 and the volume V2 of the second sub-cavity 134a2 satisfy the relationship V1>V2. In this way, the volume of the air in the first sub-cavity 134a1 is larger, the heat insulation effect of the first sub-cavity 134a1 can be improved, the heat conducted to the outside of the energy-concentrating pot support 134 through the first sub-cavity 134a1 can be reduced, and energy concentration can be better achieved, so that more heat is used for heating the pot.

[0143] In some embodiments, the volume V1 of the first sub-cavity 134a1 and the volume V2 of the second sub-cavity 134a2 also satisfy the relationship V2

[0144] It should be noted that even if the heat insulation performance of the first sub-cavity 134a1 is improved, in actual use scenarios, a part of the heat will still be conducted to the second energy concentrating disc 1343 and then transferred to the air outside the energy concentrating pot support 134. Therefore, the air outside the energy concentrating pot support 134 is introduced into the second sub-cavity 134a2 to exchange heat with the second energy concentrating disc 1343 by the fan 1332 in the present application, so as to absorb this part of heat and transfer it to the inside of the gas stove 1 by means of air flow, so as to increase the initial temperature of the primary air mixed with gas for combustion, thereby improving the combustion efficiency of the gas and further improving the thermal efficiency of the gas stove 1.

[0145] In some embodiments, the third energy concentrating disc 1344 includes a third bottom plate part 13441 and a fourth side plate part 13442. Wherein, in the height direction Z of the box structure, the third bottom plate part 13441 is located between the first bottom plate part 13421 and the second bottom plate part 13433 and is arranged opposite to the first bottom plate part 13421 and the second bottom plate part 13433, and the third bottom plate part 13441 is connected to the second side plate part 13431 on the side close to the burner 131. One side of the fourth side plate part 13442 is connected to the side of the third bottom plate part 13441 away from the burner, and the other side of the fourth side plate part 13442 is connected to the third side plate part 13432, and the fourth side plate part 13442 extends obliquely relative to the third bottom plate part 13441. That is, the first bottom plate part 13421, the first side plate part 13422, the second side plate part 13431, the third side plate part 13432, the third bottom plate part 13441 and the fourth side plate part 13442 enclose a closed first sub-cavity 134a1, so that the first sub-cavity 134a1 is divided into two parts in communication with each other, one part is arranged around the burner 131 and extends substantially in the vertical direction Z of the height direction of the box structure, and the other part extends obliquely upward along the height direction Z of the box. The second side plate part 13431, the third side plate part 13432, the second bottom plate part 13433, the third bottom plate part 13441 and the fourth side plate part 13442 enclose a closed second sub-cavity 134a2. Similarly, the second sub-cavity 134a2 also includes two parts, one part extends in the vertical direction Z of the height direction of the box structure, and the other part extends obliquely upward along the height direction Z of the box. In this way, the first sub-cavity 134a1 and the second sub-cavity 134a2 can play a heat insulation role in different directions, and can limit the heat at the burner 131 in different directions to ensure that the heat is relatively concentrated in the heating area formed by the energy concentrating pot support 134.

[0146] In some embodiments, the second bottom plate portion 13433 and the third bottom plate portion 13441 are arranged in parallel, and the minimum distance d1 between the first bottom plate portion 13421 and the third bottom plate portion 13441 in the height direction Z of the box structure is greater than the maximum distance d2 between the third bottom plate portion 13441 and the second bottom plate portion 13433. That is, in the case where the volume V1 of the first sub-cavity 134a1 is greater than the volume V2 of the second sub-cavity 134a2, the minimum thickness (d1) of the first sub-cavity 134a1 in the height direction Z of the box structure is greater than the maximum thickness (d2) of the second sub-cavity 134a2 in the height direction Z of the box structure. In this way, the first sub-cavity 134a1 can have sufficient air thickness, ensuring that the first sub-cavity 134a1 can better perform heat insulation, and the heat loss of the fire can be effectively reduced.
