Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a heat collection cover and burner. Background Art

[0002] To improve gas utilization and reduce heat loss from the stove, a heat collection shroud is usually installed in the stove burner. In most stoves currently on the market, the heat collection shrouds use the formation of an air layer to enhance heat collection efficiency, but the internal structure of the heat collection shrouds is mostly quite complex, and the insulation layer is quite thick. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing heat collection hood having a relatively complex internal structure and a large thickness of heat insulation cover, and to provide a heat collection hood and burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides a heat collection cover, which includes an upper cover, a lower cover, a heat insulation plate, and a lower pot support;

[0006] The upper cover and the lower cover are connected and cover the lower cover, forming a hollow cavity between the upper cover and the lower cover. The heat insulation plate is disposed in the cavity, and the heat insulation plate isolates the cavity into two air layers, upper and lower. The lower pot support includes a plurality of vertically arranged lower corner pieces. The upper end of the lower corner pieces extends into the cavity and is connected to the heat insulation plate, and the lower end of the lower corner pieces extends to the bottom of the lower cover.

[0007] In this design, multiple lower corner plates of the lower pot support extend into the cavity of the heat collector hood to support the heat insulation plate. This not only supports the entire heat collector hood but also secures the heat insulation plate within the cavity, simplifying its structure and resulting in a more streamlined and thinner overall structure for the heat collector hood. The heat insulation plate isolates the cavity into two air layers, achieving multi-layer insulation, increasing heat collection efficiency, and improving thermal performance.

[0008] Preferably, the lower corner piece includes a lower corner piece body and a first protrusion at the upper end of the lower corner piece. The lower cover has a first through hole in the vertical direction. The first protrusion extends into the cavity through the first through hole. The upper surface of the lower corner piece body abuts against the lower surface of the lower cover.

[0009] In this design, the first protrusion of the lower corner piece extends into the cavity through the first through hole, thereby fixing the lower corner piece to the lower cover. The upper surface of the lower corner piece body abuts against the lower surface of the lower cover, increasing the contact area between the lower corner piece and the lower cover, so that the lower corner piece can more stably support the entire heat collection cover.

[0010] Preferably, the heat insulation plate is provided with a first connection hole, and the first protrusion extends at least partially into the first connection hole and is connected to the first connection hole.

[0011] In this design, the first protrusion of the lower corner piece extends into the first connecting hole and connects with the first connecting hole, thereby enabling the lower corner piece to support the heat insulation plate.

[0012] Preferably, the lower corner piece further includes a stepped portion, which is connected to the first protrusion, and the upper end surface of the stepped portion abuts against the lower end surface of the heat insulation plate.

[0013] In this design, the stepped portion serves two purposes: firstly, it supports the heat insulation board; secondly, the stepped portion facilitates the alignment of the first protrusion of the lower corner piece with the first connecting hole of the heat insulation board.

[0014] Preferably, the heat collection cover further includes an upper pot support, which includes a plurality of vertically arranged upper corner pieces, the upper corner pieces being disposed on the upper surface of the upper cover.

[0015] In this design, the upper part of the lid is equipped with a pot support to support the pot.

[0016] Preferably, the upper corner piece includes an inclined portion located at the upper end of the upper corner piece and at one end of the upper corner piece facing the center of the heat collection hood, the inclined portion sloping downward from the radially outer side of the heat collection hood to the radially inner side of the heat collection hood.

[0017] In this design, the upper corner piece includes an inclined section, which makes the shape of the upper corner piece more compatible with the bottom of the pot, providing more stable support for the bottom of the pot.

[0018] Preferably, the upper corner piece includes an upper corner piece body and a second protrusion at the lower end of the upper corner piece, the upper surface of the upper cover is provided with a second through hole, the second protrusion extends into the cavity through the second through hole, and the lower surface of the upper corner piece body abuts against the upper surface of the upper cover.

[0019] In this design, the second protrusion of the upper corner piece extends into the cavity through the second through hole, and the lower surface of the upper corner piece body abuts against the upper surface of the upper cover, thereby fixing the upper corner piece to the upper cover.

[0020] Preferably, the upper cover includes an upper cover body and a first extension, the first extension extending downward from the outer periphery of the upper cover body; the lower cover includes a lower cover body and a second extension, the second extension extending upward from the outer periphery of the lower cover body.

[0021] The first extension extends at least partially into the lower cover, and the outer peripheral surface of the first extension abuts against the inner peripheral surface of the second extension.

[0022] In this design, the outer periphery of the upper cover extends into and abuts against the outer periphery of the lower cover, thereby fixing the outer peripheries of the upper and lower covers.

[0023] Preferably, the upper cover includes an upper cover body and a third extension, the third extension extending downward from the inner periphery of the upper cover body; the lower cover includes a lower cover body and a fourth extension, the fourth extension extending downward from the inner periphery of the lower cover body.

[0024] The fourth extension extends at least partially into the upper cover, and the outer peripheral surface of the fourth extension is located radially outside the inner peripheral surface of the third extension.

[0025] In this design, the inner circumference of the lower cover extends into the inner circumference of the upper cover, and the outer circumferential surface of the fourth extension of the lower cover is located radially outside the inner circumferential surface of the third extension of the upper cover, thereby enclosing the inner circumferences of the upper and lower covers, preventing overflow liquid from flowing into the heat collection hood, and facilitating cleaning.

[0026] This invention also provides a burner that includes the aforementioned heat collection shroud.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] This invention provides a heat collection hood and a burner. Multiple lower corner plates of the heat collection hood's lower pot support extend into the cavity of the hood to support the heat insulation plate. This not only supports the entire heat collection hood but also secures the heat insulation plate within the cavity, simplifying the heat insulation plate's structure and resulting in a simpler, thinner overall structure for the heat collection hood. The heat insulation plate isolates the cavity into upper and lower air layers, achieving multi-layer insulation, increasing the heat collection effect, and improving thermal efficiency. The burner incorporating the aforementioned heat collection hood has the same effects. Attached Figure Description

[0060] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0061] like Figure 1-Figure 3 As shown, this embodiment provides a heat collection cover 1, which includes an upper cover 2, a lower cover 3, a heat insulation plate 4, and a lower pot support 7.

[0062] The upper cover 2 and the lower cover 3 are connected and cover the lower cover 3. A hollow cavity 5 is formed between the upper cover 2 and the lower cover 3. The heat insulation plate 4 is located in the cavity 5 and isolates the cavity 5 into two air layers. The lower pot support 7 includes a plurality of vertically arranged lower corner pieces 71. The upper end of the lower corner piece 71 extends into the cavity 5 and is connected to the heat insulation plate 4. The lower end of the lower corner piece 71 extends to the bottom of the lower cover 3.

[0063] The upper cover 2 and the lower cover 3 are annular, but other suitable shapes are not limited to be used in other embodiments. There are four lower corner pieces 71, but other suitable numbers are not limited to be used in other embodiments. The lower corner pieces 71 are evenly arranged around the circumference of the heat collection cover 1, and those skilled in the art can choose other suitable arrangements as needed. The lower corner pieces 71 are connected to the heat insulation plate 4 by snap-fit, but other suitable connection methods are not limited to be used in other embodiments.

[0064] Multiple lower corner plates 71 of the lower pot support 7 extend into the cavity 5 of the heat collector shroud 1 to support the heat insulation plate 4. While supporting the entire heat collector shroud 1, they also fix the heat insulation plate 4 within the cavity 5, simplifying the structure of the heat insulation plate 4 and making the overall structure of the heat collector shroud 1 simpler and thinner. The heat insulation plate 4 isolates the cavity 5 into two air layers, achieving multi-layer insulation, increasing the heat collection effect, and improving thermal efficiency.

[0065] like Figure 1 As shown, the lower corner piece 71 includes a lower corner piece body 711 and a first protrusion 712 located at the upper end of the lower corner piece 71. The lower cover 3 has a first through hole 32 extending vertically. The first protrusion 712 passes through the first through hole 32 and extends into the cavity 5. The upper surface of the lower corner piece body 711 abuts against the lower surface of the lower cover 3.

[0066] The first protrusion 712 is rectangular, but is not limited to other suitable shapes, such as circles, in other embodiments. In other alternative embodiments, the upper surface of the lower corner piece body 711 may not abut against the lower surface of the lower cover 3.

[0067] The first protrusion 712 of the lower corner piece 71 extends into the cavity 5 through the first through hole 32, and the upper surface of the lower corner piece body 711 abuts against the lower surface of the lower cover 3, thereby fixing the lower corner piece 71 to the lower cover 3.

[0068] The heat insulation plate 4 is provided with a first connection hole 41, and the first protrusion 712 extends at least partially into the first connection hole 41 and is connected to the first connection hole 41.

[0069] The first protrusion 712 of the lower corner piece 71 extends into the first connecting hole 41 and is connected to the first connecting hole 41, thereby enabling the lower corner piece 71 to support the heat insulation plate 4.

[0070] The lower corner piece 71 also includes a stepped portion 713, which is connected to the first protrusion 712. The upper end face of the stepped portion 713 abuts against the lower end face of the heat insulation plate 4 to support the heat insulation plate 4, thus creating a hollow air layer between the heat insulation plate 4 and the lower cover 3 by spacing. In other alternative embodiments, the upper end face of the stepped portion 713 may not abut against the lower end face of the heat insulation plate 4, and the heat insulation plate 4 may be positioned on the lower corner piece 71 entirely by the cooperation of the first connecting hole 41 and the first protrusion 712. The first connecting hole 41 and the first protrusion 712 are interference-fitted. In other alternative embodiments, the first connecting hole 41 and the first protrusion 712 may also be selectively gap-fitted, with the upper end face of the stepped portion 713 abutting against the lower end face of the heat insulation plate 4 for support.

[0071] The heat collection cover 1 also includes an upper pot support 6, which includes a plurality of vertically arranged upper corner pieces 61, which are located on the upper surface of the upper cover 2.

[0073] The upper corner plate 61 includes an inclined portion 613, which is located at the upper end of the upper corner plate 61 and at the end of the upper corner plate 61 facing the center of the heat collection cover 1. The inclined portion 613 is inclined downward from the radial outer side to the radial inner side of the heat collection cover 1.

[0074] The upper corner piece 61 includes an inclined portion 613, which makes the shape of the upper corner piece 61 more compatible with the bottom of the pot and provides more stable support for the bottom of the pot.

[0075] The upper corner piece 61 includes an upper corner piece body 611 and a second protrusion 612 located at the lower end of the upper corner piece 61. The upper surface of the upper cover 2 is provided with a second through hole 22. The second protrusion 612 passes through the second through hole 22 and extends into the cavity 5. The lower surface of the upper corner piece body 611 abuts against the upper surface of the upper cover 2.

[0076] The second protrusion 612 of the upper corner piece 61 extends into the cavity 5 through the second through hole 22, and the lower surface of the upper corner piece body 611 abuts against the upper surface of the upper cover 2, thereby fixing the upper corner piece 61 to the upper cover 2. In other alternative embodiments, the lower surface of the upper corner piece body 611 may not abut against the upper surface of the upper cover 2.

[0077] The upper cover 2 includes an upper cover body 21 and a first extension 23, the first extension 23 extending downward from the outer periphery of the upper cover body 21; the lower cover 3 includes a lower cover body 31 and a second extension 33, the second extension 33 extending upward from the outer periphery of the lower cover body 31.

[0078] The first extension 23 extends at least partially into the lower cover 3, and the outer peripheral surface of the first extension 23 abuts against the inner peripheral surface of the second extension 33.

[0079] The outer periphery of the upper cover 2 extends into and abuts against the outer periphery of the lower cover 3, thereby fixing the outer peripheries of the upper cover 2 and the lower cover 3. In other alternative embodiments, the outer periphery of the lower cover 3 may also extend into and abut against the outer periphery of the upper cover 2.

[0080] The upper cover 2 includes an upper cover body 21 and a third extension 24, the third extension 24 extending downward from the inner periphery of the upper cover body 21; the lower cover 3 includes a lower cover body 31 and a fourth extension 34, the fourth extension 34 extending downward from the inner periphery of the lower cover body 31.

[0081] The fourth extension 34 extends at least partially into the upper cover 2, and the outer peripheral surface of the fourth extension 34 is located radially outside the inner peripheral surface of the third extension 24.

[0082] The inner periphery of the lower cover 3 extends into the inner periphery of the upper cover 2, and the outer periphery of the fourth extension 34 of the lower cover 3 is located radially outside the inner periphery of the third extension 24 of the upper cover 2, thereby enclosing the inner peripheries of the upper cover 2 and the lower cover 3.
