Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0049] As described in the background section, power boards can suffer damage when subjected to high-power motor loads. Research has revealed that this problem arises because the heat dissipation efficiency is low during the heatsink fins' contact with the air.

[0050] To address the aforementioned issues, this utility model provides an oil fume treatment device and integrated stove. Since the casing is made of metal, a metal heat sink is installed between the power board assembly and the casing. The heat transfer efficiency between the metal heat sink and the casing is higher than that between the heat dissipation fins and the air, thereby accelerating the heat dissipation of the power board assembly and preventing damage caused by excessively high temperatures.

[0051] The fume treatment device and integrated stove provided in this utility model embodiment will be described in detail below with reference to specific embodiments.

[0052] like Figure 1 As shown, this embodiment of the utility model provides an oil fume treatment device, including a housing 10, a fan, a power board assembly 20, and a metal heat sink 30. The housing 10 has a smoke collection chamber; the fan is disposed within the smoke collection chamber; the power board assembly 20 is mounted on the housing 10 and is electrically connected to the fan; the metal heat sink 30 is mounted on the power board assembly 20 and at least partially contacts the housing 10.

[0053] The casing 10 is made of metal, and the metal heat sink 30 is also made of metal, which makes the heat transfer efficiency between the metal heat sink 30 and the casing 10 higher than the heat transfer efficiency between the heat sink fins and the air.

[0054] In some examples, both the housing 10 and the metal heat sink 30 are made of cold-rolled steel. Cold-rolled steel has a higher thermal conductivity than air. The heat sink fins can be made of aluminum. The thermal conductivity between the metal heat sink 30 and the housing 10 is higher than the thermal conductivity between the heat sink fins and the air.

[0055] After the metal heat sink 30 transfers the heat of the power board assembly 20 to the enclosure 10, the heat can be quickly distributed by the enclosure 10 itself, thereby cooling down the power board assembly 20.

[0056] The oil fume treatment device provided in this embodiment of the utility model transfers the heat generated by the power board assembly 20 to the housing 10 through the metal heat sink 30. The heat conduction efficiency between the metal heat sink 30 and the housing 10 is higher than that between the heat sink fins and the air, thereby accelerating the heat dissipation of the power board assembly 20 and thus avoiding the problem of damage caused by the power board assembly 20 due to excessive temperature.

[0057] The power board assembly 20 is installed on the side panel of the housing 10; the power board assembly 20 can convert the input AC power into DC power required by the equipment, and the power board assembly 20 provides the power required for the operation of the fan; the fan generates negative pressure during operation, thereby sucking away the oil fumes generated during cooking.

[0058] In one possible implementation, such as Figure 1 As shown, the power board assembly 20 includes an insulating component 21 and a power board 22; the insulating component 21 is mounted on the housing 10, the power board 22 is mounted on the insulating component 21, the metal heat sink 30 is mounted on the insulating component 21, and thermally conductive adhesive 40 is provided between the metal heat sink 30 and the power board 22.

[0059] The insulating component 21 is made of insulating material; in this example, it is plastic. The housing 10 is made of metal. The insulating component 21 is installed between the power board 22 and the housing 10 to effectively prevent leakage between them.

[0060] In some examples, the power board 22 can be mounted on the insulating component 21 by bolting or by adhesive bonding.

[0061] In some examples, the power board 22 includes a printed circuit board and multiple resistors disposed on the printed circuit board. The heat source of the power board assembly 20 originates from the resistors, and thermally conductive adhesive 40 is specifically disposed on the resistors. By filling the space between the resistors and the metal heat sink 30 with thermally conductive adhesive 40, heat exchange between the resistors and the metal heat sink 30 can be ensured.

[0062] It should be noted that, although the surface of the metal heat sink 30 appears smooth, it is actually covered with uneven micro-grooves under a microscope. When the metal heat sink 30 and the power board 22 are in direct contact, only a part of the area is in contact, while the rest of the area is filled with air, resulting in extremely poor thermal conductivity. The thermally conductive adhesive 40 is a viscous paste. After being applied, it is pressed to fill the uneven gaps and squeeze out the air, thereby effectively improving the thermal conductivity between the metal heat sink 30 and the power board 22.

[0063] Thermally conductive adhesive 40, also known as thermally conductive silicone, is a silicone compound made primarily of organic silicone with added thermally conductive materials and other polymeric components. It possesses good thermal conductivity and electrical insulation properties. By placing thermally conductive adhesive 40 between the power board 22 and the metal heat sink 30, the thermal conductivity between the two components can be ensured. Furthermore, the insulating properties of the thermally conductive adhesive 40 itself can prevent leakage between the power board 22 and the metal heat sink 30.

[0064] For example, the thermally conductive adhesive 40 is elastic and needs to be applied to the power board 22 first, and then the metal heat sink 30 and the insulating part 21 are installed. During the installation process, the metal heat sink 30 applies pressure to the thermally conductive adhesive 40.

[0065] refer to Figure 2 and Figure 3 As shown, the enclosure 10 also includes two mounting strips 11, which are fixed to the side plate of the enclosure 10. The insulating component 21 is connected to the two mounting strips 11 on both sides of the power board assembly 20 along its length.

[0066] The length direction of the power board assembly 20 is the X direction.

[0067] In some examples, reference Figure 4 and Figure 5 As shown, the mounting strip 11 is fixed to the side plate of the housing 10 by bolts. The two mounting strips 11 form a limiting space 111 between themselves and the housing 10.

[0068] In some examples, reference Figures 4 to 7 As shown, the metal heat sink 30 and the insulating component 21 are installed by bolts. Then, the metal heat sink 30 and the power board assembly 20 move along arrow L1, and the insulating component 21 can be inserted into the limiting space 111. The insulating component 21 and the mounting strip 11 are fixed by bolts.

[0069] It should be noted that the insulating component 21 is provided with a handle 211. During subsequent maintenance, maintenance personnel can remove the insulating component 21 from the limiting space 111 by pulling the handle 211, which facilitates subsequent maintenance.

[0070] like Figure 8 As shown, the heat sink includes a heat transfer base 31, a first connecting wall 32, and a heat sink 33. The heat transfer base 31 is disposed on the side of the power board 22 away from the insulating member 21. Thermal conductive adhesive 40 is disposed between the heat transfer base 31 and the power board 22. The heat sink 33 is disposed between the insulating member 21 and the housing 10. The first connecting wall 32 is connected between the heat transfer base 31 and the heat sink 33.

[0071] The power board 22 is connected to the heat transfer base 31 through the thermally conductive adhesive 40. The heat on the power board 22 is first transferred to the heat transfer base 31, and then the heat transfer base 31 transfers the heat to the heat sink 33 through the first connecting wall 32. Since the heat sink 33 is located between the insulating component 21 and the housing 10, the heat sink transfers the heat to the housing 10.

[0072] In some examples, the first connecting wall 32 is perpendicularly connected to the heat transfer seat 31 and the heat dissipation seat 33, respectively, the heat transfer seat 31 and the heat dissipation seat 33 are parallel, and the heat dissipation seat 33 is in contact with the housing 10.

[0073] In one possible implementation, such as Figure 8 As shown, the metal heat sink 30 also includes a second connecting wall 34 and a third connecting wall 35 connected to the heat transfer base 31. The second connecting wall 34 and the third connecting wall 35 are respectively disposed on both sides of the power board 22 in the length direction of the power board assembly 20, and the first connecting wall 32 is disposed on one side of the power board 22 in the width direction of the power board assembly 20, so that the metal heat sink 30 can wrap around the power board 22.

[0074] The first connecting wall 32, the second connecting wall 34 and the third connecting wall 35 are each provided with at least one heat dissipation hole 301.

[0075] The width direction of the power board assembly 20 is the Y direction.

[0076] In some examples, the second connecting wall 34 and the third connecting wall 35 are perpendicularly connected to the heat transfer base 31. The second connecting wall 34 is parallel to the third connecting wall 35.

[0077] The number of heat dissipation holes 301 can be increased or decreased according to the dimensions of the first connecting wall 32, the second connecting wall 34, and the third connecting wall 35. By providing heat dissipation holes 301 on the first connecting wall 32, the second connecting wall 34, and the third connecting wall 35, the heat inside the metal heat sink 30 can be transferred to the outside of the metal heat sink 30 through the heat dissipation holes 301, preventing heat from accumulating inside the metal heat sink 30.

[0078] For example, the first connecting wall 32 is provided with seven heat dissipation holes 301, the second connecting wall 34 is provided with four heat dissipation holes 301, and the third connecting wall 35 is provided with four heat dissipation holes 301.

[0079] The heat dissipation hole 301 is elliptical in shape; the shape of the heat dissipation hole 301 can also be adjusted according to actual needs.

[0080] In some examples, the first connecting wall 32 is provided with a cable bundling hole 302, and the second connecting wall 34 and the third connecting wall 35 are both provided with cable threading holes 303. This arrangement allows wires connected to the power board 22 to pass through the cable bundling hole 302 and the cable threading hole 303, facilitating wiring.

[0081] The cable tie hole 302 can be used to fix the wires.

[0082] The number and position of the wire harness holes 302 can be adjusted according to actual needs.

[0083] In some examples, there are two wire-binding holes 302, which are located on both sides of the first connecting wall 32.

[0084] The number and position of the wire-passing holes 303 on the second connecting wall 34 can be adjusted according to actual needs. The number and position of the wire-passing holes 303 on the third connecting wall 35 can be adjusted according to actual needs.

[0085] In some examples, a wire hole 303 is provided on both the second connecting wall 34 and the third connecting wall 35. The wire hole 303 on the second connecting wall 34 and the wire hole 303 on the third connecting wall 35 are located close to the first connecting wall 32.

[0086] In one possible implementation, a protective sleeve 304 is installed on the wire hole 303 on the second connecting wall 34; and / or, a protective sleeve 304 is installed on the wire hole 303 on the third connecting wall 35. It is understood that a protective sleeve 304 may be installed on the wire hole 303 on the second connecting wall 34. Alternatively, a protective sleeve 304 may be installed on the wire hole 303 on the third connecting wall 35. Alternatively, both the wire holes 303 on the second connecting wall 34 and the third connecting wall 35 may be equipped with protective sleeves 304.

[0087] It should be noted that the wire hole 303 is formed by cutting sheet metal. The edge of the sheet metal is sharp, and the friction between the wire and the wire hole 303 can easily damage the wire. The protective sleeve 304 covers the sharp edge, and the friction between the protective sleeve 304 and the wire will not damage the wire. The protective sleeve 304 plays a protective role for the wire.

[0088] In some examples, a protective sleeve 304 is installed on the wire hole 303 on the second connecting wall 34. The protective sleeve 304 is a rubber sleeve and is connected to the wire hole 303 by adhesive or snap-fit.

[0089] like Figure 9As shown, in one possible implementation, the second connecting wall 34 and the third connecting wall 35 are symmetrically arranged relative to the heat transfer base 31 along the center line L2 extending in the width direction of the power board assembly 20. This arrangement ensures that the second connecting wall 34 and the third connecting wall 35 are identical. Since the metal heat sink 30 is formed by bending the first connecting wall 32, the second connecting wall 34, and the third connecting wall 35 after laser cutting of the sheet metal part, when the second connecting wall 34 is identical to the third connecting wall, the bending direction does not need to be considered during the bending process, reducing the operational difficulty of the bending process.

[0090] In some examples, the second connecting wall 34 and the third connecting wall 35 are bent at the edges away from the heat transfer base 31, and mounting holes 305 are provided on their bent portions, which are connected to the insulating member 21 by bolts.

[0091] See in some examples Figure 8 As shown, the metal heat sink 30 has an opening 306 on one side of the power board assembly 20 in the width direction.

[0092] The opening 306 is located on the side of the metal heat sink 30 away from the first connecting wall 32. This arrangement allows wires connected to the power board 22 to pass through the opening 306, facilitating wiring. Furthermore, during the installation of the metal heat sink 30 and the power board assembly 20, the insulating member 21 is partially inserted between the heat transfer base 31 and the heat sink 33, and the opening 306 of the metal heat sink 30 allows it to avoid obstructing the power board 22 during the insertion of the insulating member 21.

[0093] In some examples, the metal heat sink 30 has a flange 307 at the edge of the opening 306.

[0094] The opening 306 is formed by laser cutting sheet metal. The edge of the sheet metal is sharp, and friction between the wire and the opening 306 can easily damage the wire. The flange 307 provided at the edge of the opening 306 can prevent the wire from passing through the sharp edge, thus protecting the wire.

[0095] For example, bending the heat transfer base 31, the second connecting wall 34 and the third connecting wall 35 at one end toward the opening 306 can form a flange 307.

[0096] This utility model embodiment provides an integrated stove, including the above-mentioned fume treatment device.

[0097] The fume treatment device in this embodiment has the same structure as the fume treatment device provided in any of the above embodiments, and can bring the same or similar technical effects. It will not be described in detail here, but can be referred to the description of the above embodiments.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
