Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a burner and a stove. Background Art

[0002] A stove is a common kitchen appliance, mainly used for direct fire cooking, and is an indispensable appliance in life. A stove usually includes a panel, a burner, and a pot rack. The panel is installed on the stove, and a mounting hole for the burner to pass through is provided on the panel. The pot rack is arranged outside the burner and is used to place cooking utensils for cooking.

[0003] In the related art, the burner includes a ignition divider and a burner head. The ignition divider has an air mixing chamber. The burner head is used to supply primary air and gas to the air mixing chamber. A secondary air inlet is provided on the periphery of the ignition divider. The combustion efficiency of the burner can be improved by primary air supply and secondary air supplement. However, no matter whether the burner is in high-power mode or low-power mode, the ventilation volume of the secondary air inlet cannot be adaptively adjusted, so that the amount of secondary air entering from the secondary air inlet remains constant. When the burner is in low-power mode, if the amount of secondary air is too large, although the gas can be fully burned, the excess air will reduce the direct fire temperature of the burner to a certain extent, thereby affecting the cooking efficiency and causing the energy consumption of the burner to be high.

[0044] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0045] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0046] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0047] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0048] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0049] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0050] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0051] The present application provides a stove, which includes a panel, a burner, a pot rack and a control module. The burner part passes through the mounting hole of the panel and is protruding from the surface of the panel. The pot rack is arranged outside the burner and is used to place cooking utensils. The control module is used to control the opening and closing of the burner and adjust the opening size of the burner. During the cooking process of the user, different types of pot racks can be replaced as needed, and the opening size and opening and closing of the burner can be controlled by the control module. Among them, the control module can be a knob control module or a touch screen control module. The stove can have two or more burners of any number, which can be customized according to user needs, and there is no limitation here. When the number of burners is two or more, the opening size and opening and closing of any burner can still be independently operated by at least two control modules.

[0052] Figure 1 FIG. 1 shows a partial structural schematic diagram of the burner provided in the present application. Figure 1 As shown, the burner includes a base (not shown in the figure), an ignition divider 100, a burner head 200, an inner ring fire cover 300 and an outer ring fire cover 400. The ignition divider 100 and the burner head 200 are both installed on the base. The ignition divider 100 has an air mixing chamber, and the burner head 200 is used to supply primary air and fuel gas to the air mixing chamber; the ignition divider 100 includes an inner ring fire cover seat 101 and an outer ring fire cover seat 102. The inner ring fire cover seat 101 is used to support and install the inner ring fire cover 300, and the outer ring fire cover seat 102 is used to support and install the outer ring fire cover 400. The outer ring fire cover seat 102 is arranged outside the inner ring fire cover seat 101 and forms a secondary air containing groove 103 between the inner ring fire cover seat 101. A secondary air inlet 104 connected to the secondary air containing groove 103 is opened on the side wall of the ignition divider 100. During the operation of the burner, the combustion efficiency of the burner can be improved through the primary air supply at the burner head 200 and the secondary air supplement at the secondary air inlet 104 .

[0053] However, no matter whether the burner is in high-power mode or low-power mode, the ventilation volume of the secondary air inlet 104 cannot be adaptively adjusted, so that the amount of secondary air entering from the secondary air inlet 104 remains constant. When the burner is in low-power mode, if the amount of secondary air is too large, although the gas can be fully burned, the excess air will reduce the direct fire temperature of the burner to a certain extent, thereby affecting the cooking efficiency and causing the energy consumption of the burner to be high.

[0054] In order to solve the above problems, the burner provided in the present application also includes a mounting plate and an adjusting mechanism. The mounting plate is installed on the base, and the adjusting mechanism is installed on the mounting plate and is used to adjust the amount of secondary air entering from the secondary air inlet 104 according to the working mode of the burner, so that the amount of secondary air matches the combustion mode, so as to achieve the goal of reducing the gas energy consumption of the burner while ensuring the combustion efficiency.

[0055] Figure 2 A schematic diagram of an exploded view of a burner provided in the present application having an adjustment mechanism is shown. Figure 3 The schematic diagram of the structure of the regulating mechanism provided by the present application is shown. Figures 2 to 3 As shown, the regulating mechanism includes a driver 1 and a blocking member 2. The driver 1 is mounted on the mounting plate 500. The driver 1 is used to drive the blocking member 2 to move in a direction close to or away from the secondary air inlet 104 to regulate the air intake of the secondary air inlet 104 so that the secondary air volume matches the combustion mode, so as to reduce the gas energy consumption of the burner while ensuring the combustion efficiency.

[0056] In this embodiment, three secondary air inlets 104 are arranged at intervals along the circumference of the ignition divider 100, the number of blocking members 2 is the same as the number of secondary air inlets 104, and the blocking members 2 are arranged in a one-to-one correspondence with the secondary air inlets 104. In other embodiments, the secondary air inlets 104 can also be any number such as one, two, four, or five, the number of blocking members 2 is the same as the number of secondary air inlets 104, and the blocking members 2 are arranged in a one-to-one correspondence with the secondary air inlets 104.

[0057] In this embodiment, the adjustment mechanism further includes a transmission assembly, which includes an input transmission module and at least two output transmission modules 4 that are transmission-connected to the input transmission module, each output transmission module 4 is connected to each blocking member 2 in a one-to-one correspondence, and the driving end of the driver 1 is transmission-connected to the input transmission module to simultaneously drive all the output transmission modules 4 to drive the blocking member 2 to move. Of course, in other embodiments, each blocking member 2 may be equipped with a driver 1, and each driver 1 drives the blocking member 2 connected thereto to move, so as to adjust the air intake volume of the corresponding secondary air inlet 104.

[0058] It is understandable that there are multiple ways to adjust the air intake of the secondary air inlet 104. First, the air intake can be adjusted by adjusting the ventilation area inside the secondary air inlet 104. In this case, the blocking member 2 can move along the extension direction of the secondary air inlet 104, and the air intake can be adjusted by adjusting the depth of the blocking member 2 inserted into the secondary air inlet 104. Second, the air intake can be adjusted by adjusting the ventilation area outside the secondary air inlet 104. In this case, the blocking member 2 can move in the height direction relative to the secondary air inlet 104 to adjust the area of ​​the secondary air inlet 104 blocked by the blocking member 2, thereby adjusting the air intake. Those skilled in the art can make corresponding designs according to specific circumstances, and no limitation is made here.

[0059] For ease of understanding, this application takes “the blocking member 2 can move along the extension direction of the secondary air inlet 104 to adjust the air intake volume of the secondary air inlet 104” as an example to specifically illustrate the structure of the adjustment mechanism and its working principle.

[0060] In this embodiment, the secondary air inlet 104 extends in the radial direction of the ignition distributor 100, the blocking member 2 is arranged opposite to the secondary air inlet 104, and the driver 1 drives all the blocking members 2 to reciprocate in the radial direction of the ignition distributor 100 through the transmission assembly. The driver 1 can be a servo motor, which has the advantages of high precision, fast dynamic response, good stability, and long life.

[0061] In addition, the outer contour of the blocking member 2 is adapted to the inner contour of the secondary air inlet 104, and the blocking member 2 can be embedded in the secondary air inlet 104 when it moves toward the secondary air inlet 104. For example, the cross-sectional shape of the secondary air inlet 104 can be a fan ring, and the cross-sectional shape of the blocking member 2 is also a fan ring.

[0062] The input transmission module includes a first gear 31, which is transmission-connected with the driving end of the driver 1. The output transmission module 4 includes a second gear 41, an eccentric wheel 42, a connecting member 43 and a guide stopper (not shown in the figure). The second gear 41 is meshed with the first gear 31; the eccentric wheel 42 is eccentrically connected with the second gear 41; the first end of the connecting member 43 contacts the wheel surface of the eccentric wheel 42, and the other end thereof is fixedly connected with the blocking member 2; the guide stopper has a guide groove extending in the radial direction of the fire distributor 100, and the connecting member 43 is slidably matched with the guide groove so that the connecting member 43 can only slide along the guide groove and will not rotate with the eccentric wheel 42. The driver 1 drives the first gear 31 to rotate, the first gear 31 drives the second gear 41 to rotate, and the second gear 41 drives the eccentric wheel 42 to rotate eccentrically when rotating. Under the action of the eccentric wheel 42 and the guide groove of the guide stopper, the connecting member 43 moves linearly along the guide groove, that is, the connecting member 43 reciprocates along the radial direction of the fire distributor 100.

[0063] In this embodiment, there are three output transmission modules 4, and the second gears 41 of the three output transmission modules 4 are evenly distributed around the first gear 31 and mesh with the first gear 31. When the first gear 31 rotates, the three second gears 41 rotate synchronously, thereby causing the corresponding connecting member 43 to drive the blocking member 2 connected thereto to move in a direction close to the secondary air inlet 104 or away from the secondary air inlet 104.

[0064] Figure 4 Shows Figure 3 Schematic diagram of the structure of the output transmission module 4. Figure 5 Shows Figure 4 A cross-sectional schematic diagram of the eccentric wheel 42. Figures 4 to 5 As shown, in order to ensure that the connecting member 43 is always in contact with the wheel surface of the eccentric wheel 42, the eccentric wheel 42 has a sliding limit groove 420 arranged around the peripheral side wall of the eccentric wheel 42; the first end of the connecting member 43 is slidably accommodated in the sliding limit groove 420 along the circumferential direction of the eccentric wheel 42. Further, the sliding limit groove 420 includes a sliding groove portion 4201 and a limit portion 4202, the height of the sliding groove portion 4201 in the axial direction of the eccentric wheel 42 is greater than the height of the limit portion 4202 in the axial direction of the eccentric wheel 42, the first end of the connecting member 43 has a slider 431 and an extension portion 432 connected to the slider 431, the slider 431 is slidably matched with the sliding groove portion 4201, and the extension portion 432 extends from the limit portion 4202 and is fixedly connected to the second end of the connecting member 43. In other words, the opening size of the sliding limit groove 420 is smaller than its internal size, and the size of the slider 431 at the first end of the connecting member 43 is equivalent to the internal size of the sliding limit groove 420, and cannot be detached from the opening of the sliding limit groove 420, so that the slider 431 is always in contact with the wheel surface of the eccentric wheel 42 located in the sliding limit groove 420.

[0065] In order to facilitate the assembly of the eccentric wheel 42 and the connecting member 43, the eccentric wheel 42 includes an upper grooved plate 421, a connecting shaft 422 and a lower grooved plate 423. The upper grooved plate 421 and the lower grooved plate 423 are respectively detachably connected to the two ends of the connecting shaft 422 in the axial direction, and the groove surface of the upper grooved plate 421, the side wall surface of the connecting shaft 422 and the groove surface of the lower grooved plate 423 jointly form the above-mentioned sliding limit groove 420. During assembly, the lower grooved plate 423 is first fixedly connected to the connecting shaft 422, and then the slider 431 of the connecting member 43 is placed in the groove of the lower grooved plate 423, and then the upper grooved plate 421 is fixed to the connecting shaft 422. Furthermore, the outer surface of the slider 431 that matches the connecting shaft 422 is an arc surface, and the arc surface is smoothed to reduce the friction between the connecting shaft 422 and the slider 431.

[0066] Next, the working mode of the burner provided in the present application and the status of the corresponding regulating mechanism are described in conjunction with the accompanying drawings.

[0067] Figure 6 A structural schematic diagram of the burner provided in the present application in the flame-off mode is shown. Figure 7 for Figure 6 Schematic diagram of the cross section of the burner. Figure 6 to Figure 7 As shown, the burner is in the off mode, that is, the user is not using the cooker. At this time, the blocking member 2 completely blocks the secondary air inlet 104 , and the secondary air cannot enter the secondary air receiving groove 103 from the secondary air inlet 104 .

[0068] Figure 8 A schematic structural diagram of the burner provided in the present application in a low-fire mode is shown. Fig. 9 for Figure 8 Schematic diagram of the cross section of the burner. Figures 8 to 9 As shown, the user starts the burner and adjusts the burner to a low-fire mode (the low-fire mode may be to generate a direct fire only at the inner ring fire cover 300 of the burner), the driver 1 (see Figure 2 ) drives the first gear 31 to rotate, and the first gear 31 drives the connecting member 43 and the blocking member 2 to move in a direction away from the secondary air inlet 104 through the second gear 41 and the eccentric wheel 42, so that the blocking member 2 moves out of the secondary air inlet 104. At this time, a small amount of air can enter the secondary air containing groove 103 through the secondary air inlet 104 to provide air to the direct fire at the inner ring fire cover 300, thereby improving the combustion efficiency of the fuel gas.

[0069] Fig.10 A schematic structural diagram of the burner provided by the present application in a high fire mode is shown. Fig.11 for Fig.10 Schematic diagram of the cross section of the burner. Figure 10 to Figure 11 As shown, the user starts the burner and adjusts the burner to a high-fire mode (the high-fire mode can be a mode where both the inner ring fire cover 300 and the outer ring fire cover 400 of the burner generate direct fire), the driver 1 (see Figure 2 ) drives the first gear 31 to rotate, and the first gear 31 drives the connecting member 43 and the blocking member 2 to move in a direction away from the secondary air inlet 104 through the second gear 41 and the eccentric wheel 42, so that the blocking member 2 is completely moved out of the secondary air inlet 104, and the secondary air inlet 104 is in a fully open state. At this time, a large amount of air enters the secondary air containing groove 103 through the secondary air inlet 104 to provide air to the direct fire at the inner ring fire cover 300 and the outer ring fire cover 400, thereby improving the combustion efficiency of the fuel gas.

[0070] In summary, the working process of the stove provided by the present application is as follows: when the stove is not turned on, the blocking member 2 is embedded in the secondary air inlet 104, completely blocking the secondary air inlet 104; after the stove is turned on, in the low-fire mode, the blocking member 2 moves outward along the radial direction of the stove under the drive of the driver 1, opens part of the space of the secondary air inlet 104, and the secondary air inlet 104 can be partially replenished with air, and the opening area can be determined according to the load during use; when the stove is turned on to the maximum fire mode, in order to ensure the combustion efficiency, more air needs to be replenished, therefore, the blocking member 2 moves outward along the radial direction of the stove under the drive of the driver 1 until it is completely separated from the secondary air inlet 104, and the secondary air inlet 104 is fully opened to achieve the maximum amount of air supply. Finally, when the stove is finished using, the adjustment mechanism restores the blocking member 2 to the initial state of non-use, so that the blocking member 2 completely covers the secondary air inlet 104.

[0071] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
