Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a filter assembly and a range hood. Background Art

[0002] A tabletop range hood is a new type of portable range hood used to remove cooking fumes. Compared to traditional range hoods, which are fixed above the kitchen stove, tabletop range hoods offer greater flexibility and can be used in smaller spaces like living rooms. Existing tabletop range hoods typically consist of an inclined hood body, within which a filter assembly, a diagonal impeller, and a motor are positioned sequentially along the airflow path.

[0003] The technical solutions in the existing technology usually use a filter group to directly filter the oil stains. However, the current effect of using a filter group to filter oil smoke is not ideal. For example, if a filter with a relatively small aperture is used to improve the filtering effect of the filter, the damping of the fan operation will be greater. Utility Model Content

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] Optionally, the filter assembly provided in the present application further includes a plurality of condensation rods, each of the condensation rods is installed on the condensation filter, and each of the condensation rods is evenly distributed on the condensation filter.

[0008] The beneficial effect of this technical solution is that: in this way, the semiconductor refrigeration plate can also cool the multiple condensation rods located on the condensation filter, which is equivalent to increasing the area of ​​the condensation filter, thereby improving the condensation effect of the filter assembly on the flue gas.

[0009] Optionally, the length direction of each condensation rod is parallel to the flow direction of the airflow.

[0010] The beneficial effect of this technical solution is that: in this way, the condensation rod has relatively little obstruction to the air flow, and while improving the smoke condensation effect, it is not easy to have a significant impact on the working damping of the exhaust fan.

[0011] Optionally, each of the condensation rods is fixed to the leeward side.

[0012] The beneficial effect of this technical solution is that: in this way, the condensation rod can further condense the residual flue gas filtered by the condensation filter. When the length direction of the condensation rod is parallel to the flow direction of the airflow, the condensation rod has the longest distance condensation effect, and the condensation effect using the condensation rod is also relatively ideal; at the same time, using the condensation rod to condense the flue gas is an auxiliary method of using the condensation filter to condense the flue gas. Fixing each of the condensation rods on the leeward side makes it less likely that the condensation rod will hinder the flue gas from entering the condensation filter, thereby obtaining a relatively good condensation effect.

[0013] Optionally, the condensation filter is a curved mesh or a spherical mesh.

[0014] The beneficial effect of this technical solution is that when the filter assembly provided in this application is applied to a range hood, the condensation filter can provide a smoke condensation structure with a larger area in a relatively limited space, thereby achieving a better smoke condensation effect.

[0015] Optionally, the filter assembly provided in the present application further includes thermally conductive silica gel and a heat sink block, and the semiconductor refrigeration plate further includes a heating part connected to the refrigeration part, and the heating part is connected to the thermally conductive silica gel and the heat sink block in sequence.

[0016] The beneficial effect of this technical solution is that: in this way, the heat generated by the heating part can be quickly conducted away by the thermally conductive silica gel and quickly diffused by the heat dissipation block; the heat dissipated by the heat dissipation block can be carried away by the airflow after passing through the condensation filter.

[0017] Optionally, the filter assembly provided in the present application also includes multiple heat sinks, the condensation filter, the refrigeration part, the heating part, the thermal conductive silicone and the heat sink are coaxially arranged and connected in sequence, each of the heat sinks is fixed to the heat sink, and each of the heat sinks is evenly distributed around the axial direction of the heat sink.

[0018] The beneficial effect of this technical solution is that: in this way, the components are arranged on the path of air flow, the heat diffused by the heat dissipation block and the heat dissipation fins can be carried away by the air flow, and the obstruction of the air flow by the components is relatively small.

[0019] Another aspect of the present application provides a range hood, comprising a mounting tube, an exhaust fan and a filter assembly provided in the present application, wherein the exhaust fan and the filter assembly are both installed in the mounting tube, and the other side of the mesh surface of the condensation filter is the windward surface, and the windward surface is arranged facing the exhaust fan.

[0021] The beneficial effect of this technical solution is that: in this way, the oil and water condensed by the refrigeration part and the condensation filter can enter the oil collecting box through the second connecting port. When the oil and water in the oil collecting box reach a certain amount, the oil collecting box can be removed from the mounting tube and poured out, and then the first connecting port and the second connecting port are threadedly connected.

[0022] Optionally, the range hood provided in the present application further includes a base and a connecting member, one end of the connecting member is fixed to the mounting tube, and the other end of the connecting member and the top end of the base are interconnected via a universal structure.

[0023] The beneficial effect of this technical solution is that: in this way, the base can be used to support other parts of the range hood. The user can place the range hood in a part that is conducive to rapid suction and purification of oil fumes as needed, improve the efficiency of oil fume purification, and adjust the angle of the installation tube as needed.

[0024] The technical solution provided by this application can achieve at least one of the following beneficial effects:

[0025] The filter assembly and range hood provided by the present application, the refrigeration part of the semiconductor refrigeration plate cools the condensation filter, the oil smoke and water vapor condense on the condensation filter, the condensed water adsorbs or dissolves the water-soluble substances and hydrophilic substances in the flue gas, and the condensed oil stains adsorb and dissolve the fat-soluble substances, and then the oil stains and water drip or flow downward under the action of gravity. In this way, the range hood using the filter assembly provided by the present application can improve the effect of the range hood in filtering oil smoke without using a filter with a smaller aperture, avoiding the problem of increased exhaust fan working damping caused by using a filter with a smaller aperture; at the same time, compared with setting the windward side of the condensation filter to face the semiconductor refrigeration plate, the leeward side of the condensation filter in the present application faces the refrigeration part, which can make it difficult for the semiconductor refrigeration plate to block the oil smoke entering the range hood, reducing the possible adverse effects of the use of the semiconductor refrigeration plate on the range hood's flue gas filtering.

[0041] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0044] like Figures 1 to 3 As shown, the present application provides a filter assembly, including a condensation filter 16 and a semiconductor refrigeration plate 05, wherein the semiconductor refrigeration plate 05 includes a refrigeration part, which is fixedly connected to the condensation filter 16, and one side of the mesh surface of the condensation filter 16 is the leeward side, and the leeward side is arranged facing the semiconductor refrigeration plate 05.

[0045] When the filter assembly provided by the present application is used in a range hood, the refrigeration unit of the semiconductor refrigeration plate 05 cools down the condensation filter 16, and the oil smoke and water vapor condense on the condensation filter 16. The condensed water adsorbs or dissolves the water-soluble substances and hydrophilic substances in the flue gas, and the condensed oil stains adsorb and dissolve the fat-soluble substances. Then, under the action of gravity, the oil stains and water drip or flow downward. In this way, the range hood using the filter assembly provided by the present application can improve the effect of the range hood in filtering oil smoke without using a filter with a smaller aperture, thereby avoiding the problem of increased exhaust fan working damping caused by using a filter with a smaller aperture. At the same time, compared with setting the windward side of the condensation filter 16 facing the semiconductor refrigeration plate 05, the leeward side of the condensation filter 16 facing the refrigeration part in the present application can make it difficult for the semiconductor refrigeration plate 05 to block the oil smoke entering the range hood, thereby reducing the adverse effects that the use of the semiconductor refrigeration plate 05 may have on the range hood's flue gas filtering.

[0046] Optionally, the filter assembly provided in the embodiment of the present application further includes a plurality of condensation rods 06, each of which is mounted on the condensation filter 16, and each of which is evenly distributed on the condensation filter 16. In this way, the semiconductor refrigeration sheet 05 can also cool the plurality of condensation rods 06 located on the condensation filter 16, which is equivalent to increasing the area of ​​the condensation filter 16, thereby improving the condensation effect of the filter assembly on the flue gas. In the embodiment of the present application, the specific number of condensation rods 06 can be selected based on specific factors such as the area of ​​the condensation filter 16 and the power of the exhaust fan. For example, it can be 4 to 20, for example, it can be 8, 12 or 16.

[0047] Optionally, the length of each condensation rod 06 is parallel to the direction of airflow. In this way, the condensation rod 06 creates relatively little obstruction to airflow, thereby improving the smoke condensation effect while not significantly affecting the operating damping of the exhaust fan. In this embodiment of the present application, the majority of the airflow is generated by the exhaust fan, and the direction of the airflow can be defined as parallel to the axial direction of the exhaust fan.

[0048] Optionally, each of the condensation rods 06 is fixed to the leeward side. In this way, the condensation rods 06 can further condense the residual flue gas filtered by the condensation filter 16. When the length direction of the condensation rod 06 is parallel to the airflow direction, the condensation rod 06 has the longest condensation effect, and the condensation effect of the condensation rod 06 is relatively ideal. At the same time, the condensation of the flue gas by the condensation rod 06 is an auxiliary method for the condensation of the flue gas by the condensation filter 16. By fixing each of the condensation rods 06 to the leeward side, the condensation rods 06 are less likely to hinder the flue gas from entering the condensation filter 16, thereby obtaining a relatively good condensation effect.

[0049] Optionally, the condensation filter 16 is a curved or spherical mesh. Thus, when the filter assembly provided herein is applied to a range hood, the condensation filter 16 can provide a relatively large smoke condensation structure within a relatively limited space, thereby achieving a better smoke condensation effect. It is understood that the curved mesh refers to the condensation filter 16 being able to form part of the side of a cylinder or a cone; the spherical mesh refers to the condensation filter 16 being able to form part of the outer surface of a sphere.

[0050] Optionally, the filter assembly provided in this embodiment further includes thermally conductive silicone rubber 02 and a heat sink 04. The semiconductor refrigeration sheet 05 further includes a heating portion connected to the cooling portion, which is sequentially connected to the thermally conductive silicone rubber 02 and the heat sink 04. In this manner, heat generated by the heating portion can be rapidly conducted away by the thermally conductive silicone rubber 02 and rapidly dissipated by the heat sink 04. Heat dissipated by the heat sink 04 can be carried away by the airflow after passing through the condensation filter 16. In this embodiment, the heat sink 04 is preferably a metal block.

[0051] Optionally, the filter assembly provided in the embodiment of the present application further includes a plurality of heat sink fins 03. The condensation filter 16, the refrigeration unit, the heating unit, the thermally conductive silicone rubber 02, and the heat sink 04 are coaxially arranged and sequentially connected. Each heat sink fin 03 is fixed to the heat sink 04, and each heat sink fin 03 is evenly distributed axially around the heat sink 04. In this way, each component is arranged in a path where airflow flows, and the heat diffused by the heat sink 04 and the heat sink fins 03 can be carried away by the airflow, and the obstruction of the airflow by each component is relatively small. In the embodiment of the present application, the heat sink fin 03 is preferably a metal sheet.

[0052] Another aspect of the present application provides a range hood, comprising an installation tube 01, an exhaust fan 14 and a filter assembly provided in an embodiment of the present application, wherein the exhaust fan 14 and the filter assembly are both installed in the installation tube 01, and the other side mesh surface of the condensation filter 16 is the windward surface, which is arranged facing the exhaust fan 14.

[0054] The range hood provided by the present application adopts the filter assembly provided by the present application. When used in the range hood, the refrigeration part of the semiconductor refrigeration plate 05 cools the condensation filter 16, and the oil smoke and water vapor condense on the condensation filter 16. The condensed water adsorbs or dissolves the water-soluble substances and hydrophilic substances in the flue gas, and the condensed oil stains adsorb and dissolve the fat-soluble substances. Then, under the action of gravity, the oil stains and water drip or flow downward. In this way, the range hood using the filter assembly provided by the present application can improve the effect of the range hood in filtering oil smoke without using a filter with a smaller aperture, thereby avoiding the problem of increased working damping of the exhaust fan 14 caused by using a filter with a smaller aperture. At the same time, compared with setting the windward side of the condensation filter 16 facing the semiconductor refrigeration plate 05, the leeward side of the condensation filter 16 in the present application faces the refrigeration part, which can make it difficult for the semiconductor refrigeration plate 05 to block the oil smoke entering the range hood, thereby reducing the adverse effects that the use of the semiconductor refrigeration plate 05 may have on the range hood's flue gas filtering.

[0055] Optionally, the filter assembly provided in this embodiment further includes an oil collection box 08 having a first connection port 09 and a second connection port 07 formed on the mounting tube 01.

The second connection port 07 is detachably connected to the first connection port 09 and is positioned below the refrigeration unit and the condensation filter 16. This allows oil and water condensed from the refrigeration unit and the condensation filter 16 to enter the oil collection box 08 through the second connection port 07. Once the oil and water in the oil collection box 08 reach a certain level, the oil collection box 08 can be removed from the mounting tube 01 and emptied. After emptying, the first connection port 09 is then threadedly connected to the second connection port 07. Preferably, the oil collection box 08 also has an observation window 17, through which the collected oil and water in the oil collection box 08 can be observed. The second connection port 07 is threadedly connected to the first connection port 09.

[0056] Optionally, the filter assembly provided in this embodiment further includes a base 10 and a connector 18. One end of the connector 18 is fixed to the mounting tube 01, and the other end of the connector 18 is connected to the top of the base 10 via a universal joint. This allows the base 10 to support other components of the range hood, allowing the user to position the range hood in a location that facilitates rapid fume extraction and purification, improving fume purification efficiency and adjusting the angle of the mounting tube 01 as needed. Preferably, the other end of the connector 18 is a ball end 13, and the top of the base 10 is a bowl end 11. The ball end 13 mates with the bowl end 11, forming a universal joint. This allows the user to adjust the angle of the mounting tube 01 as needed to suit the application environment and improve fume extraction and purification efficiency. Preferably, a locking bolt 12 is also mounted on the bowl end 11, which is rotated to secure or release the ball end 13. Of course, the ball end 13 and the ball bowl end 11 can achieve the limitation and positioning between the two by only the damping effect. In the embodiment of the present application, preferably, the range hood further includes a switch 15 connected to both the exhaust fan 14 and the semiconductor cooling plate 05, and the switch 15 is used to control the simultaneous start and stop of the exhaust fan 14 and the semiconductor cooling plate 05.
