[0002] Range hoods are commonly used equipment in kitchens, mainly used to extract fumes generated during cooking. After long-term use of the range hood, a large amount of oil and dirt is easily accumulated on the internal fume extraction impeller, which breeds bacteria, thus causing health problems for users. Currently, there are related technologies to solve the above problems. For example, a Chinese patent with application number 201610753035.1 discloses an improved range hood, including: a casing; a fan having a impeller, the fan being detachably mounted on the casing; a refrigeration mechanism mounted on the casing and provided with at least one; a cleaning mechanism, which is used to receive condensed water generated by the refrigeration mechanism and heat it into high-temperature steam and then send it into the rotation track of the impeller of the fan.

[0003] Although the prior art has disclosed a technical solution for cleaning the wind wheel by high-temperature steam, in this technical solution, the motor in the fan structure is arranged at the rotation center of the wind wheel. In order to facilitate the installation of the motor and ensure the structural strength of the wind wheel, a support ring is arranged between the front and rear sides of the wind wheel. However, the support ring is blocked between the nozzle and the rear side of the wind wheel, so that the steam cannot directly contact the fan blades on the rear side of the wind wheel, resulting in an unsatisfactory steam cleaning effect. Therefore, in the existing technical solution, the scope of steam cleaning is limited, the cleaning effect is poor, and there is a certain room for improvement. Therefore, it is necessary to design a multifunctional steam range hood cleaning machine. Summary of the invention

[0008] The cleaning mechanism at least comprises a front nozzle and a rear nozzle for conveying steam. The front nozzle and the rear nozzle are respectively arranged at the front and rear sides of the wind wheel and convey the steam into the rotating track of the wind wheel.

[0009] As a further improvement of the present invention, the front nozzle extends into the interior of the wind wheel and is circumferentially provided with a plurality of nozzles facing the wind wheel.

[0010] As a further improvement of the present invention, the nozzle of the front nozzle is arranged to be inclined toward the inner side of the wind wheel.

The steam generator is installed in the chassis and is located on the upper side of the fan. The water tank is connected to the steam generator through a water inlet pipe. The steam generator is connected to the front nozzle and the rear nozzle at the same time through a steam outlet pipe. The steam generator draws water from the water tank and heats it to form steam. The steam enters the front nozzle and the rear nozzle along the steam outlet pipe.

[0013] As a further improvement of the present invention, the side wall of the body is recessed inward to form a receiving cavity, and the water tank is embedded in the receiving cavity and is detachably connected to the receiving cavity.

[0014] As a further improvement of the present invention, the water tank is connected to the water inlet pipe via a telescopic tube, or the water inlet pipe and the water tank are detachably connected and the connecting ends of the two can be closed.

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figures 1 to 6 As shown, the multifunctional steam range hood cleaning machine comprises:

[0031] The housing 100 includes a body 110 and a case 120 provided with a top of the body 110;

[0032] A fan 200 having a wind wheel 210 and installed in the housing 120;

[0033] The cleaning mechanism 300 at least includes a front nozzle 350 and a rear nozzle 360 ​​for conveying steam. The front nozzle 350 and the rear nozzle 360 ​​are respectively arranged at the front and rear sides of the wind wheel 210 and convey steam into the rotation track of the wind wheel 210.

[0034] By respectively arranging a front nozzle 350 and a rear nozzle 360 ​​for conveying steam on the front and rear sides of the wind wheel 210, the spray range of the steam is expanded, and the steam is prevented from being blocked by the support ring between the front and rear sides of the wind wheel 210, thereby ensuring that the steam is in full contact with the front and rear sides of the wind wheel 210, thereby improving the steam cleaning effect.

[0035] The front nozzle 350 extends into the interior of the wind wheel 210 and is circumferentially provided with a plurality of nozzles facing the wind wheel 350 .

[0036] Preferably, the front nozzle 350 is coaxially arranged with the wind wheel 210 and a plurality of nozzles are evenly arranged in the circumferential direction, so that the front nozzle 350 sprays annular steam, and the annular steam is adapted to the rotation trajectory of the wind wheel 210. When the wind wheel 210 rotates, more high-temperature steam can be brought in, and the steam cleaning effect is better. In addition, the front nozzle 350 can also be arranged on the upper side or left side of the rotation axis of the wind wheel 210 to focus on cleaning the wind wheel 210 near the smoke outlet channel.

[0037] The nozzle of the front nozzle 350 is tilted toward the inside of the wind wheel 210 to prevent the high-temperature steam from being squeezed out of the wind wheel 210 due to the wind pressure generated by the rotation of the wind wheel 210, further ensuring that the high-temperature steam is in full contact with the wind wheel 210, and the cleaning effect is better.

[0038] The rear nozzle 360 ​​extends into the interior of the wind wheel 210 and is disposed on the upper side of the rotating shaft of the wind wheel 210 , and the rear nozzle 360 ​​protrudes toward the left and right sides to form nozzles.

[0039] The rear nozzle 360 ​​is arranged on the upper side of the rotating shaft of the wind wheel 210 to avoid interference between the rear nozzle 360 ​​and the motor in the fan 200, and the left and right sides of the rear nozzle 360 ​​are raised to form nozzles to ensure that the high-temperature steam sprayed from the rear nozzle 360 ​​is in full contact with the rear side of the wind wheel 210. When the wind wheel 210 rotates, more high-temperature steam can be brought in, resulting in a better cleaning effect.

[0040] The cleaning mechanism 300 also includes a water tank 310 and a steam generator 330. The steam generator 330 is installed in the chassis 120 and is located on the upper side of the fan 200. The water tank 310 is connected to the steam generator 330 through a water inlet pipe 320. The steam generator 330 is simultaneously connected to the front nozzle 350 and the rear nozzle 360 ​​through a steam outlet pipe 340. The steam generator 330 draws water from the water tank 310 and heats it to form steam. The steam enters the front nozzle 350 and the rear nozzle 360 ​​along the steam outlet pipe 340.

[0041] The steam generator 330 is equipped with a water pump and a heating pipe. When the steam generator 330 is started, the water in the water tank 310 is pumped into the heating pipe in the steam generator 330 by the water pump, and then heated by the heating pipe to form high-temperature steam. Since the higher the temperature, the greater the air pressure, the high-temperature steam is quickly ejected along the steam outlet pipe 340, the front nozzle 350, and the rear nozzle 360 ​​under the action of pressure, and finally enters the rotation track of the wind wheel 210 driven by the wind wheel 210 to clean the oil stains on the wind wheel 210.

[0042] The steam generator 330 is arranged inside the case 120 and on the upper side of the fan 200, so that the overall layout of the range hood is more reasonable, the extra space of the case 120 is effectively utilized, and the structure is more compact. In addition, after cleaning is completed, steam condensed water will remain on the inner wall of the steam outlet pipe 340, and the steam generator 330 is arranged on the upper side of the fan 200, so that the condensed water in the steam outlet pipe 340 can be gathered under the action of gravity, so that it can be taken out at one time during the next steam cleaning, and the inside of the steam outlet pipe 340 is not easy to stink and breed bacteria, which is healthier and more hygienic.

[0043] Preferably, an increasing pump for increasing the steam pressure is also provided between the steam generator 330 and the steam outlet pipe 340, and the front nozzle 350 and the rear nozzle 360 ​​can rotate relative to the outlet pipe respectively, and when the steam is ejected from the front nozzle 350 and the rear nozzle 360, the front nozzle 350 and the rear nozzle 360 ​​are driven to rotate respectively.

[0044] By setting a booster pump to increase the pressure of the steam, the steam spray range is wider, the contact area with the wind wheel 210 is larger, and the cleaning effect is better. At the same time, the front nozzle 350 and the rear nozzle 360 ​​are set as a rotatable structure, and the high-temperature steam provides power to drive the front nozzle 350 and the rear nozzle 360 ​​to rotate, so that the high-temperature steam can penetrate into each blade of the wind wheel 210 without the wind wheel 210 rotating. In other words, the wind wheel 210 can be fully and effectively cleaned without starting the fan 200, which saves energy and is more convenient for users. Furthermore, the rotation direction of the front nozzle 350 and the rear nozzle 360 ​​is opposite to the rotation direction of the wind wheel 210, so that when the fan 200 rotates, the high-temperature steam staggeredly penetrates into the blades of the wind wheel 210, and the cleaning effect is better.

[0045] The existing water tank 310 is either installed inside the casing 100 or independently set outside the casing 100. If the water tank 310 is installed inside the casing 100, when adding water to the water tank 310, the user needs to disassemble the casing 100 to take out the water tank 310, which is very inconvenient to use. If the water tank 310 is independently set outside the casing 100, although there is no problem of inconvenience in taking and placing, the independent water tank 310 still needs to be stored somewhere in the kitchen when not in use, occupying a certain space, and the user experience is still not very good.

[0046] In order to solve the problem of placing the water tank 310, the side wall of the body 110 is recessed inward to form a receiving cavity, and the water tank 310 is embedded in the receiving cavity and is detachably connected to the receiving cavity.

[0047] By providing a receiving cavity on the side wall of the body 110 and detachably installing the water tank 310 in the receiving cavity, the remaining space of the body 110 is effectively utilized, the overall structure of the range hood is made more compact, and it is more convenient to add water to the water tank 310.

[0048] The water tank 310 is connected to the water inlet pipe 320 through a telescopic pipe. Specifically, the side wall of the accommodating cavity is provided with a through hole for the water inlet pipe 320 to pass through, and the through hole is used to support the water inlet pipe 320. One end of the water inlet pipe 320 is connected to the telescopic pipe. When the range hood is close to the water source, the water tank 310 can be directly pulled out of the accommodating cavity with the telescopic pipe and is always connected to the water inlet pipe. After the water tank 310 is filled with water, the water tank 310 and the telescopic pipe are inserted back into the accommodating cavity, so that the water tank 310 does not need to be disconnected from the water inlet pipe 320 to complete the water filling, thereby avoiding water leakage and water seepage during installation or disassembly.

[0049] Alternatively, the water inlet pipe 320 and the water tank 310 are detachably connected and both connection ends can be closed. Specifically, the water inlet pipe 320 and the water tank 310 are plug-in connected via a pair of self-sealing quick connectors. When the water tank 310 is pulled out of the water inlet pipe 320, the water inlet pipe 320 and the water tank 310 are both closed to prevent water leakage and seepage. After the water tank 310 is independently disassembled, it can adapt to the use environment where the range hood is far from the water source, and the water tank 310 is more flexible to add water.

[0050] A slide rail is installed in the accommodating cavity, and a slider is installed on the slide rail. The water tank 310 is fixedly connected to the slider. The water tank 310 extends or retracts in the accommodating cavity through the slide rail and the slider. A cover plate 311 is integrally provided on the outside of the water tank 310. When the water tank 310 is retracted in the accommodating cavity, the cover plate 311 is embedded in the accommodating cavity and is flush with the side wall of the body 110.

[0051] Through the sliding cooperation between the slide rail and the slider, the water tank 310 is guided, supported and limited in position when sliding in the accommodating cavity, so that the water tank 310 can be smoothly extended or retracted from the accommodating cavity, and the embedding depth of the water tank 310 is limited. For example, the slide rail can be a drawer slide rail, and the slider can be a roller, which is embedded in the slide rail and moves back and forth within the preset travel range of the slide rail. When necessary, the roller can also be removed from one end of the slide rail, so that the water tank 310 can be extended or retracted from the accommodating cavity like a drawer, so that the user can accurately locate the embedded position of the water tank 310 through the mutual cooperation of the slide rail and the slider, and smoothly pull out or embed the water tank 310. In addition, the cover plate 311 on the outside of the water tank 310 is set to a flush structure with the side wall of the body 110, so that the water tank 310 is hidden, and the overall integrity of the side wall of the body 110 is ensured, and the appearance is more beautiful. Preferably, the cover plate 311 and the side wall of the body 110 are made of the same material, such as stainless steel.

[0052] Since the water tank 310 is hidden, it is difficult for the user to pull out the water tank 310 directly with hands. In order to facilitate the water tank 310 to be pulled out from the accommodating cavity, the present invention can also be provided with an additional accessory, a magnetic handle with a built-in magnet, and the cover plate 311 is built with a magnetic conductive sheet. When the magnetic handle is close to the cover plate 311, it is attracted to the end cover of the water tank 310 through magnetic attraction.

[0053] When the water tank 310 needs to be pulled out, the side of the built-in magnet of the magnetic handle is brought close to the magnetic conductive sheet, and the water tank 310 and the magnetic handle are attracted by the magnetic force. Then the user can easily pull out the water tank 310 through the magnetic handle. When the magnetic handle is not needed, the magnetic handle can also be attracted to a preset position of the body 110, such as the top of the body 110 or other difficult-to-access position, so as to facilitate taking and placing and not easy to lose. In addition, the magnetic conductive sheet can be a conductive material such as an iron sheet, or a magnet can be used directly to further improve the magnetic force and ensure that the magnetic handle and the cover plate 311 are reliably attracted.

[0054] Alternatively, the slide rail is set as a push-pop-up slide rail. When the water tank 310 is embedded in the receiving groove, the water tank 310 is pressed inwardly to make the water tank 310 pop out of the receiving groove, and the cover plate 311 is separated from the side wall of the body 110. The user can easily pull out the water tank 310 by grabbing the cover plate 311. After the water tank 310 is filled with water, the water tank 310 is pressed inwardly again, and the water tank 310 can be embedded in the receiving groove again and the cover plate 311 is flush with the side wall of the body 110. The specific working principle of the push-pop-up guide rail can be referred to the Chinese patent application number 201520491389.4. Preferably, the outer side of the cover plate 311 is convex outwardly to form a convex edge, and the receiving groove is concave inwardly to form a groove corresponding to the convex edge, and the user can more conveniently grab the water tank 310 through the convex edge.

[0055] An L-shaped support rod 400 is provided at the bottom of the steam generator 330, and the horizontal part of the L-shape extends into the front side of the wind wheel 210. A rectangular ultraviolet lamp 500 is provided on the support rod 400. The front side wall of the ultraviolet lamp 500 is embedded in the vertical part of the L-shape, and the lower side wall of the ultraviolet lamp 500 is embedded in the horizontal part of the L-shape. The left side wall and the right side wall of the ultraviolet lamp 500 release ultraviolet rays to the left and right sides of the wind wheel 210 respectively.

[0056] The ultraviolet lamp 500 is extended into the interior of the wind wheel 210 by setting an L-shaped support rod 400, and the front side wall and the bottom side wall of the ultraviolet lamp 500 are respectively embedded in the vertical part and the horizontal part of the L-shaped support rod 400, so as to facilitate the assembly of the ultraviolet lamp 500 and ensure the reliability of the assembly, and prevent the ultraviolet lamp 500 from shaking and falling off in strong winds. The left side wall and the right side wall of the ultraviolet lamp 500 release ultraviolet rays to the left and right sides of the wind wheel 210 respectively, ensuring that the ultraviolet irradiation range fully covers the inside of the wind wheel 210, and the ultraviolet rays sterilize the wind wheel 210, preventing bacteria from growing inside the fan 200, and making it more hygienic and healthy.

[0057] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
