Description

Technical Field

[0001] This invention relates to the field of stove technology, and in particular to a lifting mounting bracket for an upper air intake burner. Background Technology

[0002] Lift-up cooktops are a new type of cooktop that has emerged in recent years, characterized by ease of cleaning and convenient use of the space on the cooktop panel. However, due to the limitations of their structure, there are currently no best-selling lift-up cooktop products on the market. Existing lift-up cooktops mainly fall into two categories: one type integrates the burner entirely into the main body, as described in Chinese Utility Model Patent Publication No. CN207501192U; the other type allows for the entire burner to be raised and lowered, as described in Chinese Utility Model Patent Publication No. CN217178584U.

[0003] The first type of structure requires a huge amount of space, which is difficult to meet even in integrated cooktops. For built-in cooktops, cabinets are almost impossible to accommodate this requirement. The second type of structure requires the burner to be lowered entirely. Its advantage is easier use, but the burner requires a higher positioning, making disassembly and cleaning difficult, and its greater weight can easily cause it to jam. Summary of the Invention

[0004] The purpose of this invention is to provide a lifting mounting bracket with low lifting weight, less prone to jamming, and easy disassembly and cleaning of the upper air intake burner. In order to solve one or more technical problems existing in the prior art, this invention provides at least one beneficial option or creates conditions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A lifting mounting bracket for an upper air intake burner is provided, which is configured to lift and install via a lifting mechanism. The lifting mounting bracket is provided with a slot for hanging the upper air intake burner, a nozzle mounting part for mounting a nozzle, and a probe mounting part for mounting an ignition needle and a thermocouple. A baffle plate is provided above the nozzle mounting part, and the projection of the baffle plate coincides with the projection of the nozzle mounting part.

[0007] The main advantage of this invention is that the lifting mounting bracket is only used to lift the nozzle, ignition needle, and thermocouple. The top-inlet burner is connected to the lifting mounting bracket in a detachable and flip-up manner through a slot, resulting in low lifting weight, less likelihood of jamming of the lifting mechanism, and easy disassembly and cleaning of the top-inlet burner. Using a top-inlet burner also avoids the difficulty of a large air duct by separating the air duct from the burner.

[0008] Furthermore, since the projection of the baffle plate coincides with the projection of the nozzle mounting part, when the lifting mounting bracket is in the sunken position, the nozzle mounting part can be used to avoid the hole position, and when the lifting mounting bracket is in the rising position, the baffle plate can be used to avoid the hole position, thus avoiding nozzle clogging during cleaning and ensuring waterproof performance in each position.

[0009] More preferably, the card slot is disposed on the sealing plate and located within the orthographic projection of the sealing plate.

[0010] More preferably, the slot is located inside the connecting support column where the sealing plate and the nozzle mounting part are connected.

[0011] The advantage of this setup is that as long as the upper air intake burner is not removed from the slot, it can prevent accidental switching of workstations caused by excessive descent of the lifting mounting bracket.

[0012] More preferably, the probe mounting part and the nozzle mounting part are connected by a crossbar, which is positioned below the top of the nozzle mounting part. This prevents the lifting mounting bracket from colliding with the bottom of the panel during lifting.

[0013] More preferably, the lifting mounting bracket is lifted and lowered on a base via the lifting mechanism. The lifting mechanism includes an elastic element, a positioning rod, and a positioning rail. The elastic element is connected between the base and the lifting mounting bracket to provide an upward restoring force for the lifting mounting bracket. The positioning rail is disposed on the lifting mounting bracket. One end of the positioning rod is connected to the base, and the other end of the positioning rod is movably inserted into the positioning rail and runs and is positioned along the trajectory defined by the positioning rail.

[0014] By setting the lifting mechanism as a flexible lifting and positioning mechanism, during application, the lifting mounting bracket can be manually pressed to switch between the rising position and the sinking position, making the operation convenient and simple.

[0015] More preferably, a positioning rod mounting bracket is provided on the base, and a guide groove is provided on the positioning rod mounting bracket. One end of the positioning rod is rotatably connected to the positioning rod mounting bracket, and the other end of the positioning rod passes through the guide groove and is inserted into the positioning track; the guide groove is a transverse strip groove.

[0016] The lifting mechanism used in this invention employs a combination design of positioning rod and guide groove. The components used are simple, few in number, small in size, easy to install and use, have a long service life, and low application cost. In particular, the guide groove not only guides the positioning rod, but also enhances the strength of the positioning rod when the lifting mounting bracket is in the rising or sinking position, which can effectively reduce the design size of the positioning rod.

[0017] More preferably, the positioning track is composed of a first vertical segment AB, a first inclined segment BC, a second vertical segment CD, a second inclined segment DE, a third inclined segment EF, a third vertical segment FG, and a fourth inclined segment GB connected in sequence; the first inclined segment BC is inclined to the left and upward, the second inclined segment DE is inclined to the right and downward, the third inclined segment EF is inclined to the right and upward, and the fourth inclined segment GB is inclined to the left and downward; steps are provided at the transition points of each segment, so that the positioning rod can only run along the direction ABCDEFGBA; effectively ensuring smooth switching between the two workstations and reducing mechanical failures.

[0018] More preferably, the angles between the first inclined segment BC, the second inclined segment DE, and the fourth inclined segment GB and the horizontal line are greater than 45°, while the angle between the third inclined segment and the horizontal line is less than 45°. This ensures the smoothest switching between the two working positions for the lifting mounting bracket.

[0019] More preferably, the top-intake burner includes an integrated air intake channel, a burner cap, a pot support, and a connecting rod. The air intake channel is correspondingly positioned to the nozzle, the burner cap is located at the air outlet of the air intake channel, the pot support surrounds the burner cap, and the connecting rod is used to achieve rotational connection with the easy-cleaning platform of the stove. This facilitates the flipping, disassembly, and cleaning of the top-intake burner.

[0020] More preferably, the lifting mounting bracket is installed corresponding to the cooktop panel, and the cooktop panel is provided with clearance holes corresponding to the lifting mounting bracket, so as to realize the smooth lifting and lowering of the lifting mounting bracket.

[0021] Additional aspects and advantages of the invention will become apparent in the following description or may be learned by practice of the invention. Attached Figure Description

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0037] Example 1.

[0038] Reference Figures 1-4As shown, a lifting mounting bracket 1 for an upper air intake burner of a stove is provided. It is connected to a base 3 by a lifting mechanism 2 to form a lifting mounting. The lifting mounting bracket 1 is provided with a slot 1-1 for hanging the upper air intake burner, a nozzle mounting part 1-2 for mounting the nozzle, and a probe mounting part 1-3 for mounting the ignition needle 4 and the thermocouple 5. A baffle 1-4 is provided above the nozzle mounting part 1-2. The projection of the baffle 1-4 coincides with the projection of the nozzle mounting part 1-3. The upper surface of the nozzle mounting part 1-2 is used to mount the nozzle 6.

[0039] Compared to existing technologies, the lifting mounting bracket for a top-intake burner in this invention has the following main advantages: the lifting mounting bracket 1 is only used to lift the nozzle 6, ignition needle 4, and thermocouple 5. The top-intake burner is connected to the lifting mounting bracket in a detachable and flip-up manner through a slot, resulting in low lifting weight, less likelihood of jamming of the lifting mechanism, and easy disassembly and cleaning of the top-intake burner. Using a top-intake burner also avoids the difficulty of a large gas duct by separating the gas duct from the burner.

[0040] Furthermore, since the projection of the baffle plate-4 coincides with the projection of the nozzle mounting part 1-2, when the lifting mounting bracket is in the sunken position, the nozzle mounting part 1-2 can be used to avoid the hole position, and when the lifting mounting bracket is in the rising position, the baffle plate 1-4 can be used to avoid the hole position, thus avoiding nozzle blockage during cleaning and ensuring waterproof performance in each position.

[0041] In this embodiment, the lifting mechanism 2 includes a spring 2-1, a positioning rod 2-2, and a positioning rail 2-3. The spring 2-1 is connected between the lifting mounting bracket 1 and the base 3, providing an upward restoring force for the lifting mounting bracket 3. The positioning rail 2-3 is disposed on the lifting mounting bracket 1. One end of the positioning rod 2-2 is connected to the base 3, and the other end of the positioning rod 2-2 is movably inserted into the positioning rail 2-3 and runs and is positioned along the trajectory defined by the positioning rail 2-3.

[0042] In this embodiment, a positioning rod mounting bracket 7 is provided on the base 3, and a guide groove 7-1 is provided on the positioning rod mounting bracket 7. One end of the positioning rod 2-2 is rotatably connected to the positioning rod mounting bracket 7, and the other end of the positioning rod 2-2 passes through the guide groove 7-1 and is inserted into the positioning track 2-3 so that the other end of the positioning rod 2-2 can slide smoothly within the limited trajectory of the positioning track 2-3.

[0043] Reference Figure 5 , Figure 6As shown, the positioning track 2-3 is located on the front side of the nozzle mounting part 1-2, and is composed of a first vertical section AB, a first inclined section BC, a second vertical section CD, a second inclined section DE, a third inclined section EF, a third vertical section FG, and a fourth inclined section GB connected in sequence; the first inclined section BC is inclined to the left and upward, the second inclined section DE is inclined to the right and downward, the third inclined section EF is inclined to the right and upward, and the fourth inclined section GB is inclined to the left and downward; a step (height difference) is provided at the transition of each section so that the positioning rod 2-2 can only run along the direction ABCDEFGBA.

[0044] The lifting mechanism 2 described above operates on the following principle: the initial state is the normal working state, that is, the lifting mounting bracket 3 is in the rising position (protruding above the panel). At this time, the other end of the positioning rod 2-2 is located at point A. Due to the upward elastic force of the spring 2-1, the weight of the lifting mounting bracket 1 will be counteracted. The positioning rod 2-2 is locked at point A to ensure that the lifting mounting bracket 3 will not move to a higher position.

[0045] When the lifting mounting bracket 1 sinks, a downward force is applied to it. When the gravitational force is greater than the elastic force of the spring 2-1, the lifting mounting bracket 1 begins to move downward. The positioning rod 2-2 moves upward along the slide. When it reaches the junction with the first inclined section BC, due to the height difference of the steps (the left end is a smooth rising surface, and the right end is a stop step), the positioning rod 2-2 can only move to the left and enter the first inclined section BC. Then it runs along the first inclined section BC to the second vertical section CD until it reaches point D. At this point, because it hits the top of the second vertical section CD, the positioning rod 2-2 can no longer move upward, so the force can be stopped.

[0046] After the positioning rod 2-2 reaches point D, the force is stopped. At this time, the top height of the lifting mounting bracket 1 is lower than the panel. Under the action of the spring force of spring 2-1, the lifting mounting bracket 1 will rise upward. Due to the step height difference at the transition point, the positioning rod 2-2 can only move diagonally downward along the second inclined section DE to reach point E. Point E is where the panel is parallel to the top of the lifting mounting bracket 3. At this time, a downward pressing process is completed.

[0047] The principle for the lifting and lowering of the mounting bracket 1 is the same as that for the lowering. By pressing the lifting and lowering mounting bracket 1, the balance between the elastic force of the spring 2-1, the weight of the lifting and lowering mounting bracket 1 and the tension generated by the positioning rod 2-2 is overcome, so that the positioning rod 2-2 moves along the third inclined segment EF to point F, then to point G, and then to point A. The guiding method in the middle is still to fix the direction of movement by the height difference between the two transition points.

[0048] In this embodiment, preferably, the angles between the first inclined segment BC, the second inclined segment DE, and the fourth inclined segment GB and the horizontal line are greater than 45°, while the angle between the third inclined segment and the horizontal line is less than 45°. This ensures the smoothest switching between the two working positions for the lifting mounting bracket.

[0049] It should be noted that spring 2-1 can be replaced by other existing or future known elastic components, as long as they can play the role of pushing the lifting mounting bracket to rise and reset.

[0050] It should be noted that the lifting mechanism 2 can also adopt other existing spring lifting mechanisms or other types of lifting mechanisms that can be realized in the future. The lifting mechanism can be switched between the two limit positions of rising and falling by pressing the lifting mechanism.

[0051] It should be noted that the specific air path design on the nozzle mounting part 1-2, the connection structure design between the nozzle 6 and the nozzle mounting part 1-2, and the connection structure design between the nozzle mounting part 1-2 and the air source are all common technical knowledge mastered by those skilled in the art; the connection structure design between the ignition needle 4 and the thermocouple 5 and the external circuit is also common technical knowledge mastered by those skilled in the art; it will not be described in detail here.

[0052] The lifting mechanism used in this embodiment has the advantages of simple and few components, small size, convenient installation and use, long service life, and low application cost. The lifting mechanism is powered by hand; the lifting mounting bracket 1 is pressed down to sink into the stove, and after being pressed down again, it springs back to its normal working position. Operation is simple and convenient. In particular, the guide groove 7-1 not only guides the positioning rod but also enhances the strength of the positioning rod 2-2 when the lifting mounting bracket 1 is in the rising or sinking position, effectively reducing the design dimensions of the positioning rod 2-2.

[0053] Referring to Figure 7, the upper air intake burner 8 includes an air intake channel 8-1, a flame cap 8-2, a pot support 8-3, and a connecting rod 8-4 integrated therewith. The air intake channel 8-1 is arranged corresponding to the nozzle 6. The flame cap 8-2 is located at the air outlet end of the air intake channel 8-1. The pot support 8-3 is arranged around the flame cap 8-2. The connecting rod 8-4 is connected to the pot support 8-3. The entire upper air intake burner 8 is detachably and flip-uply connected to the lifting mounting bracket 1 through the connecting rod 8-4.

[0054] Refer to Figure 1As shown, the opening of the slot 1-1 faces upward, and the upper air intake burner 8 is hooked onto the slot 1-1 via the connecting rod 8-4, thereby achieving a detachable and flip-up connection. It should be noted that the number of slots 1-1 and the shape of the connecting rod 8-4 can be customized by those skilled in the art according to actual needs. For example, in this embodiment, there are two slots 1-1 located on the same straight line, and the connecting rod 8-4 has a straight rod section that mates with the two slots 1-1; however, this is not limited to this embodiment.

[0055] Reference Figure 8 As shown, in application, the lifting mounting bracket 3 is used in conjunction with the panel 9. The panel 9 is provided with a first clearance hole 9-1, a second clearance hole 9-2 and a third clearance hole 9-3, which are used to allow the nozzle mounting part 1-2, the ignition needle 4 and the thermocouple 5 to be lifted and passed through.

[0056] In this embodiment, the slot 1-1 is preferably disposed on the baffle plate 1-4 and located within the orthographic projection of the baffle plate 1-4. In some embodiments, the slot 1-1 may be disposed on the inner side of the connecting support between the baffle plate 1-4 and the nozzle mounting portion 1-2. In this way, as long as the upper air intake burner 8 is not removed, the connecting rod 8-4 can be used to prevent the burner mounting bracket 1 from descending excessively, thereby avoiding accidental switching of the workstation.

[0057] In this embodiment, the probe mounting part 1-3 preferably has two mounting holes for mounting the ignition needle 4 and the thermocouple 5, respectively. The probe mounting part 1-3 and the nozzle mounting part 1-2 are connected and transitioned by a crossbar 1-5. The crossbar 1-5 is positioned below the top of the nozzle mounting part 1-2 to prevent the crossbar 1-5 from colliding with the bottom of the panel 9 during the lifting and lowering process of the lifting mounting bracket 1.

[0058] This embodiment provides a lifting mounting bracket for an upper air intake burner. In terms of combustion, the gas directly reaches the nozzle 6 through the pipe and valve body. There can be multiple nozzles 6, which can be set as needed. They correspond to the air intake channel 8-1 on the burner 8. Since the gas ejected from the nozzle 6 is a high-pressure fluid, it can complete the injection and mixing of gas and finally reach the vicinity of the burner cap 8-2 to complete ignition and continue combustion.

[0059] The upper air intake burner 8 is flipped up along the axial direction of the slot 1-1 because there is a corresponding slot 1-1 for the connecting rod 8-4 on the lifting mounting bracket 1.

[0060] The burner mounting bracket 1 is lowered and installed by means of a lifting mechanism 2. The lifting mechanism 2 has two limiting positions, one for rising and one for lowering, which correspond to the rising position and the lowering position of the burner mounting bracket 1, respectively.

[0061] Easy to clean. For general cleaning, the upper air intake burner 8 can be flipped up directly to perform a preliminary cleaning of the panel 9. For thorough cleaning, the upper air intake burner 8 can be removed vertically, and the lifting mounting bracket 1 can be lowered to form a flat plane with the panel 9. Cleaning is convenient, and the upper air intake burner 8 can be placed directly in the water tank for rinsing, cleaning, and drying. After being lowered, there is no need to worry about the nozzle holes being blocked during thorough cleaning.

[0062] Space is utilized effectively. After the lifting mounting bracket 1 is lowered, its height is consistent with the panel, and it is a flat surface without any obstructions. Food ingredients, cooking tools, bowls, and plates can be placed on this flat surface, which is very close to the pots and pans being used, making it convenient to use.

[0063] It should also be noted that in the description of this invention, directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0064] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "at least" means one or more, unless otherwise explicitly specified.

[0065] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0066] In this invention, unless otherwise specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "below," and "over" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Above," "below," and "below" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
