Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a self-cleaning oil cup and range hood. Background Technology

[0002] Range hoods, as appliances used to treat kitchen grease, are widely used for air purification in kitchens. Considering the oil fumes produced during cooking, grease will eventually accumulate in the grease cup of the range hood as it is used over time. After running for a period of time, the range hood will store the condensed grease in the grease cup, which can be removed and emptied periodically. However, if consumers do not empty the grease cup frequently, the grease will adhere to the cup, making it difficult to clean, time-consuming, and laborious. The grease-covered, hard-to-clean grease cup causes considerable inconvenience for consumers.

[0003] The oil cup, an essential component of range hoods for collecting and separating grease, is usually detachably mounted on the outer casing. However, cleaning it presents significant inconveniences: when the grease level is high, disassembly easily leads to spillage, staining clothes, the stovetop, or the floor; users then need to scrub it by hand with detergent, risking cuts from the metal material and direct contact with the grease, requiring repeated washing to clean it. The entire process—disassembly, emptying, and scrubbing—is itself a tedious household chore, especially uncomfortable in the cold winter months.

[0004] In related technologies, simply injecting the cleaning fluid into the oil cup in stages and relying solely on the cleaning fluid to clean the oil cup cannot remove the oil stains that have condensed inside the oil cup. Utility Model Content

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] Figure 1 This is a schematic diagram of a self-cleaning oil cup provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of a thermal cleaning device provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the flow of the solute in the jet. Figure 4 for Figure 2 A schematic diagram of the omnidirectional structure is provided for reference. Figures 1-4 The self-cleaning oil cup includes a cup body 20 and a thermal cleaning device 16 disposed within the cup body 20. The thermal cleaning device 16 includes a thermal jet nozzle 165. The thermal jet nozzle 165 includes an air inlet 1656 and an air jet 1658. The air inlet 1656 includes an air inlet cavity 1657, an air inlet 1653, and an airflow driving device 1651. The air inlet cavity 1657 is connected to the air inlet 1653, and the airflow driving device 1651 is located within the air inlet cavity 1657. The air jet 1658 includes a spray nozzle 1652, which is connected to the air inlet cavity 1657.

[0038] In this embodiment of the invention, the air inlet 1653, the air inlet cavity 1657, and the spray nozzle 1652 are internally connected. The jet solute can enter the air inlet cavity 1657 from the air inlet 1653 and, driven by the airflow drive device 1651, enter the launching section 1658, and be ejected through the spray nozzle 1652 in the launching section 1658. Thus, the jet solute impacts the solidified grease adhering to the cup body 20, thoroughly cleaning the solidified grease accumulated on the wall of the cup body 20, achieving automatic cleaning of the cup body 20, and improving the user experience. Furthermore, in this embodiment of the invention, the spray speed of the jet solute and the magnitude of the impact force can be reasonably controlled by adjusting the power of the airflow drive device 1651.

[0039] The jet solute may include air or steam. When the jet solute is air, the air stream ejected through nozzle 1652 impacts the solidified grease adhering to the cup body 20. When the jet solute is steam, the steam stream ejected through nozzle 1652 impacts the solidified grease adhering to the cup body 20.

[0040] Optionally, refer to Figures 1-4The launching section 1658 also includes a spray chamber 1655, which connects the air inlet chamber 1657 and the spray port 1652. The air inlet 1653, air inlet chamber 1657, spray chamber 1655, and spray port 1652 are internally connected. The radial dimension of the spray chamber 1655 is larger than that of the spray port 1652. Driven by the airflow driving device 1651, the jet solute enters the spray chamber 1655 of the launching section 1658 and then enters the spray port 1652. Because the radial dimension of the spray chamber 1655 is larger than that of the spray port 1652, the jet solute entering the spray port 1652 has a greater pressure, which increases the jet velocity of the jet solute ejected from the spray port 1652 and increases the impact force of the jet solute ejected from the spray port 1652. This is beneficial for impacting and removing solidified grease adhering to the cup body 20.

[0041] Optionally, refer to Figures 1-4 The launching unit 1658 also includes a heating element 1654, which is disposed within the spray chamber 1655. The heating element 1654 can heat the jet solute within the spray chamber 1655, and the heated jet solute is ejected through the spray nozzle 1652. The heated jet solute forms a hot jet that can not only impact the solidified grease adhering to the cup body 20 with the impact force brought by its speed, but also melt the solidified grease with its heat, thereby facilitating the impact and removal of the solidified grease adhering to the cup body 20.

[0042] Optionally, the airflow drive device 1651 includes a powered fan. The powered fan performs work on the jet solute through rotating blades, converting mechanical energy into kinetic energy and generating thrust to push the jet solute into the injection chamber 1655. On the other hand, the thrust generated by the powered fan creates a negative pressure in the air inlet chamber 1657 to draw the jet solute from the air inlet 1653 into the air inlet chamber 1657.

[0043] Optionally, the heating element 1654 includes a heating wire. A heating wire is a resistive element that converts electrical energy into heat energy, typically made of a metal or alloy material with high resistivity. When energized, the heating wire generates heat due to resistance, thus heating the jet solute.

[0044] Optionally, refer to Figures 1-4The hot cleaning device 16 also includes a rotating mechanism 166, which is connected to the hot jet nozzle 165. The rotating mechanism 166 drives the hot jet nozzle 165 to rotate, thereby driving the spray port 1652 to rotate, so that the jet solute sprayed from the spray port 1652 can be sprayed to multiple positions on the cup body 20. For example, the jet solute can be sprayed within a 360° angle range, thereby cleaning one circumference of the inner wall of the cup body 20, that is, cleaning the cup body 20 within a 360° angle range. In this embodiment of the invention, the rotating mechanism 166 reasonably controls the spray direction and range of the jet solute, so that the spray direction of the jet solute is adapted to the position of the solidified grease, and the jet solute is sprayed onto the solidified grease.

[0045] Optionally, refer to Figures 1-4 The rotating mechanism 166 includes a universal joint, which comprises a first main shaft 161, a yoke 162, a pivot 163, and a journal 164. The first main shaft 161 is connected to the yoke 162, and pivots 163 are arranged on both sides of the yoke 162, with the two pivots 163 connected by the journal 164. The hot jet nozzle 165 is connected to the first main shaft 161. The universal joint enables flexible movement or pointing in multiple directions and angles.

[0046] For example, two journals 164 intersect to form a cross. One end of a journal 164 is rotatably connected to a yoke 162 via a pivot 163, and the other end of a journal 164 is rotatably connected to a yoke 162 via another pivot 163. A first main shaft 161 is connected to the yoke 162. Thus, the upper first main shaft 161 and the lower first main shaft 161 can rotate relative to each other. The hot jet nozzle 165 is connected to the lower first main shaft 161 and moves with the lower first main shaft 161. The hot jet nozzle 165 can rotate relative to the upper first main shaft 161. The jet solute sprayed by the hot jet nozzle 165 can clean the cup 20 within a 360° angular range.

[0047] For example, the air inlet 1656 is connected to the first main shaft 161 and is located between the first main shaft 161 and the launching part 1658. The air inlet 1653 is disposed on the side wall of the air inlet 1656 and is located between the first main shaft 161 and the airflow driving device 1651. The heating element 1654 is located in the injection chamber 1655 on the side away from the injection port 1652.

[0048] For example, the lower first spindle 161 can be driven by a motor to move, so that the hot jet nozzle 165 can rotate relative to the upper first spindle 161.

[0049] Figure 5 This is a schematic diagram of another thermal cleaning device provided in an embodiment of the present invention, with reference to... Figure 5 The rotating mechanism 166 includes a universal structure, which includes a motor 171, a main rotating shaft 172 and a connecting rod shaft 173. The main rotating shaft 172 is connected to the motor 171, the first end of the connecting rod shaft 173 is connected to the outside of the main rotating shaft 172, and the second end of the connecting rod shaft 173 is connected to the hot jet nozzle 165.

[0050] For example, motor 171 drives main shaft 172 to rotate, main shaft 172 drives connecting rod shaft 173 to rotate, thereby connecting rod shaft 173 drives hot jet nozzle 165 fixed at the second end of connecting rod shaft 173 to rotate. The jet solute sprayed by hot jet nozzle 165 can clean cup body 20 within a 360° angle range. The universal structure provided in this embodiment uses connecting rod shaft 173 to connect main shaft 172 and hot jet nozzle 165, and motor 171 drives main shaft 172 to rotate, thereby driving hot jet nozzle 165 to rotate. The structure is simple and helps to reduce the volume of universal structure.

[0051] Figure 6 This is a schematic diagram of another thermal cleaning device provided in an embodiment of the present invention. Figure 7 for Figure 6 A cross-sectional structural diagram of the central universal joint, for reference. Figure 6 and Figure 7 The rotating mechanism 166 includes a universal structure, which includes a spherical hinge 181, a second main shaft 182, a slide rail 183, and a ball bearing 184. The second main shaft 182 is connected to the slide rail 183, and the ball bearing 184 is provided on the inner side of the slide rail 183. The ball bearing 184 is tangent to the spherical hinge 181. The hot jet nozzle 165 is connected to the spherical hinge 181.

[0052] For example, when it is necessary to change the pitch or yaw angle of the hot jet nozzle 165, the spherical portion of the spherical hinge 181 rolls relative to the slide rail 183. This rolling motion is supported and guided by balls 184 arranged in the track of the slide rail 183, which roll within the slide rail 183, achieving low-friction, high-precision angle adjustment.

[0053] For example, the lower end of the spherical hinge 181 can be moved by a motor, so that the hot jet nozzle 165 can rotate relative to the second spindle 182.

[0054] Figure 8 This is a schematic diagram of another thermal cleaning device provided in an embodiment of the present invention, with reference to... Figure 8The rotating mechanism 166 includes a third main shaft 191, a first connecting rod 192, a second connecting rod 193, and a third connecting rod 194. The middle part of the first connecting rod 192 is rotatably connected to the third main shaft 191. The first end of the first connecting rod 192 is connected to the first end of the second connecting rod 193, and the second end of the first connecting rod 192 is connected to the first end of the third connecting rod 194. One of the two hot jet nozzles 165 is connected to the second end of the second connecting rod 193, and the other is connected to the second end of the third connecting rod 194.

[0055] For example, the first link 192, the second link 193, and the third link 194 form a U-shaped structure. One of the two hot jet nozzles 165 is connected to the first end of the U-shaped structure, and the other is connected to the second end of the U-shaped structure. The middle part of the first link 192 is rotatably connected to the third main shaft 191, and the U-shaped structure can rotate around the third main shaft 191, thereby driving the two hot jet nozzles 165 to rotate.

[0056] Exemplarily, the rotating mechanism 166 further includes two universal joints. One end of the first universal joint is connected to the hot jet nozzle 165, and the other end is connected to the second end of the second connecting rod 193. One end of the second universal joint is connected to the hot jet nozzle 165, and the other end is connected to the second end of the third connecting rod 194. Thus, not only can the hot jet nozzle 165 rotate within a 360° range around the first connecting rod 192, but the pitch or yaw angle of the hot jet nozzle 165 can also be changed through the universal joints. The universal joints can be any one or more of the types provided in the above embodiments.

Figure 9 and Figure 10 The cup body 20 is designed to receive the oil-water mixture flowing out from the internal flow channel and air duct of the range hood. When the hot cleaning device 16 cleans the cup body 20, it needs to cover the inner surface of the cup body 20. Therefore, the radius and height of the cup body 20 need to match the component size and position of the hot cleaning device 16.

[0058] The jet solute moves outward from the thermal cleaning device 16, and diffuses in the direction perpendicular to the plane of the injection port 1652. According to the laws of planar jetting, the radius of the cup body 20 can be calculated. ,satisfy:

The length of the nozzle is 1652. The diffusion angle is [value missing]. The center point of the nozzle 1652 forms a projection point on the bottom plane of the cup body 20 along a direction perpendicular to the bottom plane of the cup body 20. The distance between this projection point and the center of the bottom plane of the cup body 20 is [value missing]. The distance between the projection point and the edge of the bottom plane of the cup body 20 is .
