Description

Technical Field

[0001] This invention belongs to the field of household stove technology, specifically relating to a liquid receiving tray for a stove and a gas stove having the liquid receiving tray. Background Technology

[0002] Household stoves (such as gas stoves) typically include a control panel, burner, drip tray, and pot support. The drip tray is located on the control panel and is used to catch spilled soup for easy cleaning, while also preventing soup from flowing into the stove and affecting its normal operation.

[0003] Existing liquid receiving trays, such as the structure disclosed in the utility model patent "Liquid Receiving Tray and Stove Burner Including the Same" (authorization announcement number CN215175318U) with patent number 202120516103.9, include a liquid receiving tray body, a burner hole in the middle of the liquid receiving tray body, a liquid receiving groove on the upper surface of the liquid receiving tray body along the circumference of the burner hole, and a first annular platform extending outward on the outer periphery of the liquid receiving groove. The first annular platform is provided with a plurality of positioning grooves for placing the feet of the pot support in the circumference.

[0004] For example, the invention patent application No. 201710994980.5, entitled "Cooktop Liquid Tray Assembly and Cooktop" (Publication No. CN107763685A), discloses a structure in which the liquid tray assembly is installed on the panel of the cooktop. The panel has an opening for the burner in the cooktop to pass through. The liquid tray assembly includes: a liquid tray body with a liquid-holding tank; and a clamping member, which is installed between the burner and the opening to press the panel onto the cooktop body. The liquid tray body is detachably installed on the clamping member, so that when cleaning the liquid tray body, it can be removed from the clamping member.

[0005] Existing drip trays are mostly equipped with drip grooves to collect spills, but these grooves are not easy to clean and often require the drip tray to be removed for cleaning. In addition, existing drip grooves can generally only collect spills from cooking utensils, and once the spills enter the burner, they generally cannot flow out again. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a drain tray for stoves that is easy to clean, in light of the current state of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a gas stove with the above-mentioned liquid receiving tray so as to provide sufficient secondary air supply.

[0008] The third technical problem to be solved by the present invention is to provide a gas stove with the above-mentioned liquid receiving tray so that the overflow liquid entering the burner can flow out.

[0009] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a drip tray for a stove, comprising:

[0010] The plate body has a mounting hole in the center for installing the burner of the stove.

[0011] Its features are:

[0012] The upper surface of the disc is provided with protrusions. There are at least two protrusions arranged circumferentially around the outer periphery of the mounting hole. Two adjacent protrusions together define a recessed guide groove. The bottom wall of the guide groove gradually slopes downward radially outward from the edge of the mounting hole.

[0013] In this way, the overflow channel can catch the overflow and allow the overflow to flow downward along the channel under its own gravity. Users can clean the overflow tray by wiping the channel and the downstream part of the channel, which is convenient and reduces cleaning dead spots.

[0014] Preferably, each of the protrusions extends radially outward from the edge of the mounting hole.

[0015] Preferably, the distance between two adjacent protrusions gradually increases radially outward. This makes the guide channel have a funnel-shaped structure with a larger outer end and a smaller inner end. This structure facilitates cleaning and further reduces cleaning dead angles, making the inner end of the guide channel easy to wipe as well.

[0016] The aforementioned protrusion can be a separate component located on the upper surface of the disc body, or it can be formed on the upper surface of the disc body. Preferably, the protrusion is integrally connected to the disc body. The integral structure facilitates cleaning.

[0017] Furthermore, the bottom wall of the guide channel has an upper edge relatively close to the mounting hole and a lower edge relatively far from the mounting hole, and the height of the upper edge is greater than the height of the lower edge;

[0018] The upper edge extends from bottom to top toward the mounting hole to form the sidewall of the guide groove, and the top edge of the sidewall engages with the edge of the corresponding mounting hole.

[0019] In the above embodiments, preferably, the upper surface of the disc has a central portion and a surrounding portion located around the periphery of the central portion, the mounting hole and the protrusion are located in the central portion, and the surrounding portions are substantially horizontal. The surrounding portions can be used to collect a portion of the overflow.

[0020] Preferably, the surrounding portion is located below the central portion, and the two are joined by an annular stepped surface.

[0021] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a gas stove having a liquid receiving tray as described above, characterized in that: it further includes a burner, the burner having:

[0022] The base is located within the mounting hole of the aforementioned liquid receiving tray.

[0023] The inner ring mixing chamber is located on the base;

[0024] An outer ring mixing chamber is located on the base, is ring-shaped and is set on the outer periphery of the inner ring mixing chamber. An annular secondary air channel is formed between the inner ring wall of the outer ring mixing chamber and the outer ring wall of the inner ring mixing chamber. At the same time, the outer ring mixing chamber is located above the protrusion of the liquid receiving plate, and the secondary air channel is connected to each guide groove.

[0025] In this way, outside air can enter the secondary air channel from the bottom through each guide groove, effectively increasing the supply of secondary air. At the same time, when secondary air enters, it often flows along the bottom wall of the guide groove. However, in this invention, the bottom wall of the guide groove gradually slopes upward radially inward, so that the secondary air can flow inward and upward along the bottom wall of the guide groove. The sloped bottom wall of the guide groove is conducive to the entry of secondary air and reduces the resistance when the secondary air enters. Furthermore, since the outer ring mixing chamber is located above the protrusion of the liquid receiving plate, cleaning can be achieved by simply inserting the wiping cloth from the outside to the inside into the guide groove.

[0026] Preferably, the base has an outer ring gas passage at the location corresponding to the outer ring mixing chamber;

[0027] The outer ring mixing chamber is supported on the base by at least two support legs, which are arranged circumferentially and are hollow inside, connecting the outer ring mixing chamber and the outer ring gas passage.

[0028] Preferably, the number of support feet is the same as the number of protrusions, and the support feet are located within the space enclosed by the protrusions and are arranged corresponding to their respective protrusions. In this way, the arrangement of the support feet will not significantly affect the replenishment of secondary air or the cleaning of the liquid receiving tray.

[0029] To further address the third technical problem mentioned above, preferably, the secondary air channel has an annular bottom wall that covers the mounting holes of the disc. In this way, overflowing liquid entering the secondary air channel can flow through the annular bottom wall onto the receiving tray under its own gravity and then flow down along the guide groove.

[0030] Compared with the prior art, the advantages of the present invention are as follows: by providing at least two protrusions on the upper surface of the disc body, each protrusion is arranged circumferentially at intervals around the outer periphery of the mounting hole of the disc body, and a recessed guide groove is defined between two adjacent protrusions. The bottom wall of the guide groove gradually slopes downward radially outward from the edge of the mounting hole. In this way, the guide groove can receive overflow liquid and allow the overflow liquid to flow downward along the guide groove under its own gravity. The user can clean the liquid receiving disc by wiping the guide groove of the liquid receiving disc and the downstream part of the guide groove, which is convenient and reduces cleaning dead corners.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-6 As shown, this is a preferred embodiment of a gas stove with a liquid collection tray and a gas stove having the liquid collection tray according to the present invention. The gas stove includes a liquid collection tray, a burner 2, a panel 3, and a pot support 4.

[0039] Among them, panel 3 has a through hole 30 that penetrates the thickness of the plate.

[0040] like Figure 1 , 2 As shown, the drip tray includes a tray body 1, which is generally horizontal. The tray body 1 is supported on the panel 3 and covers the through hole 30 on the panel 3. The upper surface of the tray body 1 has a central portion 1a and a peripheral portion 1b located around the central portion 1a. The peripheral portion 1b is generally horizontal and located below the central portion 1a, and the two are joined by an annular stepped surface 100. A mounting hole 10 for installing the burner of the stove is provided at the center of the central portion 1a. Figure 1The mounting hole 10 shown is centrally symmetrical. However, the mounting hole 10 can also be circular or other shapes. The central portion 1a is also formed with protrusions 11. There are at least two protrusions 11 (four in this embodiment) arranged at equal intervals along the circumference of the mounting hole 10. Adjacent protrusions 11 together define a recessed guide groove 12. The bottom wall 12a of the guide groove 12 gradually slopes downwards radially outwards from the edge of the mounting hole 10. In this embodiment, each protrusion 11 extends radially outwards from the edge of the mounting hole 10, and the distance between adjacent protrusions 11 gradually increases radially outwards, resulting in the guide groove 12 having a trumpet-shaped structure with a smaller inner end and a larger outer end. Furthermore, the bottom wall 12a of the flow channel 12 has an upper edge 121 that is relatively close to the mounting hole 10 and a lower edge 122 that is relatively far away from the mounting hole 10. The height of the upper edge 121 is greater than the height of the lower edge 122. The upper edge 121 extends from bottom to top toward the mounting hole 10 to form the side wall 12b of the flow channel 12. The top edge of the side wall 12b engages with the edge of the corresponding mounting hole 10 to form a flange 13.

[0041] The burner 2 described above has a base 21, an inner annular mixing chamber 22, and an outer annular mixing chamber 23.

[0042] The base 21 is located inside the mounting hole 10 of the aforementioned liquid receiving tray.

[0043] The inner ring mixing chamber 22 is located on the base 21.

[0044] An outer ring mixing chamber 23 is mounted on the base 21, forming a ring shape and positioned around the outer periphery of the inner ring mixing chamber 22. An annular secondary air channel 20 is formed between the inner ring wall of the outer ring mixing chamber 23 and the outer ring wall of the inner ring mixing chamber 22. Simultaneously, the outer ring mixing chamber 23 is located above the protrusion 11 of the liquid receiving tray, and the secondary air channel 20 is connected to each guide groove 12. The secondary air channel 20 has an annular bottom wall 200, which covers the mounting hole 10 of the tray body 1. The outer periphery of the annular bottom wall 200 extends downwards at an incline from the inside to the outside and is located above the aforementioned flange 13. Thus, the overflow accumulated on the annular bottom wall 200 can flow to the guide groove 12 of the liquid receiving tray under its own gravity. This also prevents leakage of overflow through the mounting hole 10 of the liquid receiving tray.

[0045] In this embodiment, the base 21 has an outer ring gas passage 211 at the location corresponding to the outer ring mixing chamber 23 and an inner ring gas passage 212 at the location corresponding to the inner ring mixing chamber 22. The outer ring gas passage 211 and the inner ring gas passage 212 are respectively connected to the injector assembly for gas output. The injector assembly is prior art and will not be described in detail here. The inner ring gas passage 212 is connected to the inner ring mixing chamber 22. The outer ring mixing chamber 23 is supported on the base 21 by at least two support legs 24. Each support leg 24 is arranged at equal intervals along the circumference, and the interior of each support leg 24 is hollow and connects the outer ring mixing chamber 23 and the outer ring gas passage 211. In this embodiment, the number of support legs 24 is the same as the number of protrusions 11. The support legs 24 are located within the space enclosed by each protrusion 11 and are arranged corresponding to their respective protrusions 11. See details. Figure 5 .

[0046] The aforementioned pot support 4 is supported on the periphery 1b of the liquid receiving tray body 1.

[0047] Thus, when the gas stove in this embodiment is working, secondary air can flow inward along the bottom wall of the guide groove 12 and replenish the secondary air channel 20. Furthermore, overflow can flow down along the guide groove 12, facilitating cleaning. In this invention, the funnel-shaped guide groove 12 further facilitates cleaning while also increasing the air inlet area of ​​the secondary air and accelerating the entry of the secondary air.

[0048] Meanwhile, the sidewall 12b of the guide channel 12 in this invention prevents secondary air entering from the guide channel 12 from continuing to flow radially inward, causing the secondary air to flow obliquely upward along the sidewall 12b, thus reducing the radial flow distance of the secondary air. Furthermore, combined with the inclined structure of the bottom wall of the guide channel 12, it facilitates the replenishment of secondary air, reduces resistance to the secondary air, and allows the secondary air to enter the secondary air channel 20 more smoothly. Simultaneously, the sidewall 12b of the guide channel 12 also prevents the entry of foreign objects during cleaning.
