Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a smoke collection chamber and an integrated stove including the smoke collection chamber. Background Technology

[0002] An integrated cooktop is a comprehensive kitchen appliance that integrates the functions of a range hood, cooktop, and other kitchen appliances into one unit. It can collect and remove cooking fumes in a timely manner during cooking. Integrated cooktops typically have a side-suction, down-draft structure, where fumes carrying oil droplets descend along the oil circuit system until the fumes are exhausted and the oil droplets enter the oil cup.

[0003] The existing integrated stove's oil system has a simple structure and insufficient oil drainage, leading to oil buildup in the system and on the outside of the casing after prolonged use. This accumulated oil residue is difficult to clean and easily clogs the oil outlets; furthermore, the residue is prone to deterioration, emitting a foul odor and resulting in a poor user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a smoke collection chamber and an integrated stove including the smoke collection chamber, which can prevent oil stains from accumulating on the outer shell.

[0005] To achieve this objective, the present invention employs the following technical solution:

[0006] A smoke collection chamber includes an outer shell, in which a cavity for the flow of smoke is formed. An oil leakage section is provided at the top of the outer shell, the oil leakage section connecting the cavity to the outside of the outer shell, and oil droplets located at the top of the outer shell can enter the cavity through the oil leakage section.

[0007] In one embodiment, the oil leakage section includes an oil leakage hole formed on the top of the housing.

[0008] In one embodiment, the top of the housing is a plate-shaped upper cover, and the oil leakage hole is disposed on the upper cover.

[0009] In one embodiment, the oil leakage section includes an oil leakage notch formed at the top of the housing.

[0010] In one embodiment, a raised edge is formed by protruding from the edge of the top of the housing outward, and the oil leakage notch is provided on the raised edge on the side near the cavity.

[0011] In one embodiment, the housing includes an ear plate connected to the short side of the cavity, and the oil leakage notch is located on the convex side at one end abutting against the ear plate.

[0012] In one embodiment, the oil leakage notch is triangular, with one side of the triangle located on the edge of the cavity.

[0013] On the other hand, the present invention adopts the following technical solution:

[0014] An integrated stove includes a host computer and a frame, and also includes the aforementioned smoke collection chamber, wherein the host computer and the smoke collection chamber are respectively mounted on the frame.

[0015] In one embodiment, the host computer includes a host computer back plate and a host computer base plate, with a stepped surface formed between the host computer back plate and the host computer base plate; the frame includes a frame back plate, with the top edge of the frame back plate abutting against the stepped surface; the outer shell of the smoke collection chamber includes a smoke collection chamber back plate, and the host computer base plate is lower than the top edge of the smoke collection chamber back plate.

[0016] In one embodiment, the top edge of the smoke collection chamber back plate forms a smoke collection chamber fold, the top edge of the frame back plate forms a frame fold, the frame fold covers the outside of the smoke collection chamber fold, and the frame fold abuts against the step surface.

[0017] The smoke collection chamber provided by the present invention has an oil leakage part on its outer shell. When oil overflow or oil creep occurs, the oil droplets condensed on the top of the outer shell can enter the cavity of the smoke collection chamber through the oil leakage part, which avoids the accumulation of oil on the outer shell, reduces the difficulty of cleaning, avoids clogging the oil outlet, and avoids the generation of odor due to long-term accumulation of oil.

[0018] The integrated stove provided by this invention includes the aforementioned smoke collection chamber. Oil droplets condensed on the top of the outer casing can enter the cavity of the smoke collection chamber through the oil leakage part, preventing oil stains from accumulating on the outer casing. The bottom plate of the upper computer is lower than the top edge of the back plate of the smoke collection chamber, allowing oil stains in the upper computer to fall directly into the cavity of the smoke collection chamber, preventing these oil stains from seeping out to the outside of the integrated stove and improving the efficiency of smoke removal.

[0032] This embodiment provides a smoke collection chamber and an integrated stove including the smoke collection chamber, for collecting and exhausting cooking fumes generated during cooking. Figure 1 and Figure 4 As shown, the integrated stove includes a smoke collection chamber, a host computer 3, a frame 4, an air duct impeller system 5, an exhaust chamber 6, an oil cup 7, and an air outlet 8. The outer shell 1 of the smoke collection chamber, the host computer 3, the air duct impeller system 5, the exhaust chamber 6, the oil cup 7, and the air outlet 8 are respectively installed on the frame 4. When the air duct impeller system 5 is activated, the oil fumes are discharged after passing through the host computer 3, the smoke collection chamber, the exhaust chamber 6, and the air outlet 8, and the condensed oil droplets fall into the oil cup 7.

[0033] like Figure 2 and Figure 3 As shown, a cavity 2 for flue gas circulation is formed in the outer shell 1 of the smoke collection chamber. An oil leakage part is provided at the top of the outer shell 1, which connects the cavity 2 to the outside of the outer shell 1. Oil droplets located at the top of the outer shell 1 can enter the cavity 2 through the oil leakage part.

[0034] During cooking, the fumes disperse over a wide area, making it difficult for all of them to enter the upper unit 3. Some grease may condense on the outer wall of the integrated stove. This external grease may seep down from the joint between the stove panel and the upper unit 3 onto the outer shell 1 of the fume collection chamber. In the event of oil spillage or dripping, the oil droplets on the top of the outer shell 1 can enter the cavity 2 through the oil leakage point, preventing grease from accumulating on the outer shell 1, reducing cleaning difficulty, preventing blockage of the oil outlet, and preventing odors caused by long-term grease buildup.

[0035] The oil leakage section can be a single structure or it can include multiple structures that serve an oil leakage function. For example... Figure 2 and Figure 3 As shown, the oil leakage section includes one or more oil leakage holes 11 formed on the top of the outer casing 1. The oil leakage holes 11 can be, but are not limited to, circular, elliptical, or polygonal through holes. The oil leakage holes 11 connect the inner and outer sides of the outer casing 1, allowing oil droplets located on the top of the outer casing 1 to enter the cavity 2 through the oil leakage holes 11 and eventually be discharged outdoors or collected in the oil cup 7, preventing oil droplets from accumulating on the top of the outer casing 1.

[0036] The top of the outer casing 1 is a plate-shaped upper cover 12, and an oil drain hole 11 is provided on the upper cover 12. Compared with a vertical surface, oil droplets are more likely to accumulate on the flat upper cover 12. The oil drain hole 11 allows these accumulated oil droplets to flow into the cavity 2 in a timely manner, preventing them from becoming solid or extremely viscous liquid due to long-term accumulation, thus reducing the difficulty of cleaning the outer casing 1.

[0037] Initially, the oil is liquid and has good fluidity, flowing from the higher part of the upper cover plate 12 to the lower part. To further improve the efficiency of oil collection, the oil drain hole 11 is set at the lowest point of the upper cover plate 12, so that as much oil as possible on the upper cover plate 12 can flow into the cavity 2 through the oil drain hole 11, reducing the amount of oil accumulating on the upper cover plate 12.

[0038] like Figure 2 and Figure 3 As shown, the oil leakage section includes an oil leakage notch 13 located on the top of the outer casing 1. Both the notch structure and the through-hole structure allow oil to pass through, but the difference lies in their placement: the through-hole structure is more flexible and can be placed at any location on the top of the outer casing 1 as needed, while the notch structure can only be placed on the edge of the top of the outer casing 1; droplet-shaped oil is relatively viscous and generates significant adhesion at the edge of the through-hole structure. When the oil becomes viscous enough, it will clog the through-hole structure. The semi-open shape of the notch structure reduces the adhesion force on the oil, resulting in better oil drainage. The outer casing 1 can have only the oil leakage notch 13 or the oil leakage hole 11, or both, all of which can promptly guide oil droplets located on the top of the outer casing 1 into the cavity 2, preventing oil accumulation on the top of the outer casing 1.

[0039] Based on the above structure, a raised edge 14 is formed by protruding outward from the top edge of the outer casing 1. An oil leakage notch 13 is provided on the raised edge 14 near the cavity 2. The raised edge 14 facilitates a stable connection between the outer casing 1 and the host computer 3 and other mechanisms, and also provides strength and structural stability to the outer casing 1. Because the raised edge 14 protrudes from the top of the outer casing 1, oil easily condenses on it. Providing the oil leakage notch 13 on the raised edge 14 allows for more efficient drainage of oil into the cavity 2.

[0040] The main body of the outer shell 1 is a groove-shaped box, and ear plates 15 are respectively provided on both sides of the top of the outer shell 1. In this embodiment, the top of the cavity 2 is rectangular, and the ear plates 15 are connected to the short side of the cavity 2, which can extend the length of the cavity 2 and collect the oil fumes and liquid droplets near the two sides of the upper computer 3 into the cavity 2.

[0041] Compared to the center, the airflow is smaller and the temperature is lower at the two sides of the upper unit 3, making it easier for oil droplets to condense in the fumes. The oil leakage gap 13 is located on the end of the protruding edge 14 that abuts against the ear plate 15, allowing oil droplets to reach the oil leakage gap 13 more quickly and enter the cavity 2, resulting in more thorough oil cleaning.

[0042] The specific shape of the oil leakage notch 13 is not limited, as long as it allows oil droplets to enter the cavity 2. Preferably, the oil leakage notch 13 is triangular, with one side of the triangle located on the edge of the cavity 2. The triangular structure is easy to process and has high processing efficiency. Moreover, the straight edge has low adhesion force to oil droplets, which can effectively prevent oil droplets from clogging the oil leakage notch 13.

[0043] When the oil leakage gap 13 is located at the end of the protruding edge 14 that abuts against the ear plate 15, it is only necessary to cut off a triangle at the end of the protruding edge 14 to leave a straight line on the protruding edge 14. This straight line, the straight line at the end of the ear plate 15, and the edge of the cavity 2 form a triangle. The processing difficulty is low and the obstruction to the flow of oil droplets is small.

[0044] Based on the above structure, such as Figure 4 and Figure 5 As shown, the host computer 3 includes a host computer back plate 31 and a host computer base plate 32, with a stepped surface 33 formed between the host computer back plate 31 and the host computer base plate 32. The frame 4 includes a frame back plate 41, with the top edge of the frame back plate 41 abutting against the stepped surface 33. The outer shell 1 of the smoke collection chamber includes a smoke collection chamber back plate 16, and the host computer base plate 32 is lower than the top edge of the smoke collection chamber back plate 16.

[0045] The stepped surface 33 design ensures that the base plate 32 of the host computer is lower than the top edge of the back plate 16 of the smoke collection chamber. This allows oil stains in the host computer 3 to fall directly into the cavity 2 of the smoke collection chamber, preventing them from seeping out from the connection between the host computer 3 and the back plate 16 of the smoke collection chamber or from the connection between the host computer 3 and the frame back plate 41, thus improving the efficiency of oil fume removal. In addition, the stepped surface 33 can better hold the frame back plate 41 in place, preventing accidental movement of the frame back plate 41 relative to the host computer 3, making the host computer 3 mounted on the frame 4 more stable.

[0046] To further improve the stability of the frame 4 support, the top edge of the smoke collection chamber back plate 16 forms a smoke collection chamber flange 17, and the top edge of the frame back plate 41 forms a frame flange 42. The frame flange 42 covers the outside of the smoke collection chamber flange 17 and abuts against the step surface 33.

[0047] That is, the cross-section of the smoke collection chamber folded edge 17 is inverted U-shaped, and the cross-section of the frame folded edge 42 is also inverted U-shaped. The frame folded edge 42 covers the outside of the smoke collection chamber folded edge 17, making the connection between the smoke collection chamber back plate 16 and the frame back plate 41 more stable, and preventing oil stains from seeping out from the connection between the host computer 3 and the smoke collection chamber back plate 16, resulting in a better user experience.

[0048] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
