Description

Technical Field

[0001] This utility model relates to the field of kitchen exhaust, and in particular to a kitchen ceiling exhaust hood. Background Technology

[0002] Ceiling-mounted range hoods, also known as ceiling-mounted exhaust hoods, are key components of kitchen exhaust systems. They are primarily used to efficiently collect and remove cooking fumes. Installed directly above the ceiling, they draw in fumes through negative pressure at the top. Commonly found in commercial kitchens or home kitchens with limited ceiling height, these hoods are deep and have a larger capacity, accommodating fumes that haven't been removed promptly and reducing spillage. They are particularly suitable for the high-fume environments of Chinese stir-frying. The selection of a ceiling-mounted range hood should consider exhaust efficiency, installation conditions, and subsequent maintenance costs. In home settings, a deep hood design and ease of cleaning are preferred; for commercial kitchens, integrated purification hoods are recommended, balancing safety and energy consumption control.

[0003] For example, patent number (CN211952867U) discloses a kitchen exhaust hood, including a first exhaust hood, a second exhaust hood fixedly connected to the upper right end of the first exhaust hood, an inclined air inlet at the lower right end of the first exhaust hood, a collection device installed at the middle of the lower end of the first exhaust hood, a liquid guide pipe installed at the lower left end of the first exhaust hood, and an exhaust port installed at the middle of the upper end of the first exhaust hood. A washing device is installed on both the first and second exhaust hoods, and a blocking device is fixedly installed on the second exhaust hood. This kitchen exhaust hood, as described in this utility model, creates a wind wall around the gas stove through the air jet, allowing the hood to effectively remove kitchen fumes. Adding detergent to the washing liquid tank further purifies the fumes before they are discharged outdoors; simultaneously, it solves the problem of difficult cleaning inside the exhaust hood.

[0004] Currently, when using ceiling-mounted kitchen exhaust hoods, the oil collection structure of the hoods has certain limitations. Oil stains make it difficult to see the oil collection status directly from the outside, requiring frequent manual checks to prevent oil spillage and potential fires. This is detrimental to improving the convenience and safety of using ceiling-mounted exhaust hoods.

[0005] Therefore, to address the above issues, a kitchen ceiling exhaust hood that can automatically detect the oil collection status and facilitate the disassembly and cleaning of the oil collection structure can be designed. Utility Model Content

[0006] To overcome the problem that kitchen ceiling exhaust hoods require frequent manual checks of the oil collection box, which hinders the convenience and safety of using them.

[0007] The technical solution of this utility model is as follows: a kitchen ceiling exhaust hood, including an exhaust hood shell and an oil collection box. A sealing mounting plate is fixedly installed at the lower end of the oil collection box, a tension / compression sensor is fixedly installed at the upper end of the sealing mounting plate, a connecting plate is fixedly installed at the upper end of the tension / compression sensor, a connecting rope is fixedly installed at the upper end of the connecting plate, and a floating ball is fixedly installed at the end of the connecting rope away from the connecting plate. An installation protective shell is fixedly installed at the lower end of the oil collection box, an information processing module is fixedly installed inside the installation protective shell, and an indicator light is fixedly installed at the lower end of the installation protective shell. A locking edge is fixedly installed at the upper end of the oil collection box, and arc-shaped grooves are opened on both the left and right sides of the upper end of the locking edge. An oil collection base plate is fixedly installed at the lower end of the exhaust hood shell, an oil collection port is opened on the inner side of the oil collection base plate, a locking frame is fixedly installed at the lower end of the oil collection base plate on the side of the oil collection port, and a movable groove is opened at the lower end of the oil collection base plate on the inner side of the locking frame. A spring is fixedly installed inside the movable groove, and a locking ball is fixedly installed on the spring.

[0008] Preferably, the floating ball can rise synchronously with the oil level. The taut connecting rope of the floating ball can pull the connecting plate, triggering the tension and pressure sensor. The information processing module can receive the information transmitted by the tension and pressure sensor and control the indicator light to illuminate. The oil collection base plate can work with the guide plate to guide the oil inside the exhaust hood to the oil collection port, concentrating it in the oil collection box. The spring can drive the locking ball to tightly fit the arc-shaped groove, and the locking edge can lock into the locking frame. Pulling the box body can remove the oil collection box. The oil overflow prevention plate can prevent the oil inside from overflowing, reducing the possibility of oil spillage during the process.

[0009] Preferably, the tension / compression sensor is electrically connected to the information processing module, and the information processing module is electrically connected to the indicator light.

[0010] Preferably, a power supply module is located inside the housing on the side of the information processing module, and a light-transmitting protective cover is fixedly installed at the lower end of the housing on the side of the indicator light.

[0011] As a preferred option, guide plates are fixedly installed on both the left and right sides of the upper part of the oil collecting base plate, and the locking frame is designed into a U-shaped structure.

[0012] Preferably, an oil collection and anti-overflow plate is provided on the upper side of the inside of the oil collection box, and a through groove is opened on the inner side of the oil collection and anti-overflow plate.

[0013] Preferably, the locking edge is locked to the locking frame, and the oil collection anti-overflow plate is locked to the oil collection box.

[0014] Preferably, the surface of the locking ball is slidably connected to the movable groove, and the end of the locking ball away from the spring extends to the outside of the movable groove and is adapted to the arc-shaped groove.

[0015] The beneficial effects of this utility model are:

[0016] 1. This kitchen ceiling exhaust hood uses a floating ball that rises synchronously with the oil collection level. When the collected oil reaches a set range, it triggers a tension sensor, allowing an indicator light to alert staff immediately. This facilitates timely cleaning of the oil collection box. By using an automatic detection mechanism to replace manual inspection of the oil collection status, it ensures the accuracy of oil collection status checks, reduces the burden of manual inspection, and prevents overflow of grease that could lead to a fire. This improves the convenience and safety of using the kitchen ceiling exhaust hood.

[0017] 2. This kitchen ceiling exhaust hood uses a spring to drive the locking ball to tightly fit the arc-shaped groove, ensuring a stable connection between the locking edge and the locking frame. This structure also facilitates the disassembly and installation of the oil collection box, making it suitable for oil collection boxes that require regular cleaning and improving the convenience of cleaning and disassembly. Furthermore, it works with an oil collection status detection mechanism to control the amount of oil collected in the box, and uses an oil overflow prevention plate to prevent oil spillage on the inner side, reducing the possibility of oil spillage during disassembly and cleaning.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5 This utility model provides an embodiment: a kitchen ceiling-mounted range hood, including a range hood shell 1 and an oil collection box 2. A sealing mounting plate 3 is fixedly installed at the lower end of the oil collection box 2. A tension / compression sensor 4 is fixedly installed at the upper end of the sealing mounting plate 3. A connecting plate 5 is fixedly installed at the upper end of the tension / compression sensor 4. A connecting rope 6 is fixedly installed at the upper end of the connecting plate 5. A floating ball 7 is fixedly installed at the end of the connecting rope 6 away from the connecting plate 5. A mounting cover 8 is fixedly installed at the lower end of the oil collection box 2. An information processing module 9 is fixedly installed inside the mounting cover 8. An indicator light 10 is fixedly installed at the lower end of the mounting cover 8. A locking edge 11 is fixedly installed at the upper end of the oil collection box 2. Arc-shaped grooves 12 are formed on both the left and right sides of the upper end of the locking edge 11 for oil drainage. An oil collecting base plate 13 is fixedly installed at the lower end of the fume hood shell 1. An oil collecting port 14 is opened on the inner side of the oil collecting base plate 13. A locking frame 15 is fixedly installed at the lower end of the oil collecting base plate 13 on the side of the oil collecting port 14. A movable groove 16 is opened at the lower end of the oil collecting base plate 13 on the inner side of the locking frame 15. A spring 17 is fixedly installed inside the movable groove 16. A locking ball 18 is fixedly installed on the spring 17. The floating ball 7 rises synchronously with the oil level. The connecting plate 5 is pulled by the connecting rope 6, which triggers the tension and pressure sensor 4. This causes the information processing module 9 to control the lighting of the indicator light 10, prompting the staff to deal with the oil collecting box 2 in time. This can not only ensure the accuracy of the oil collecting status inspection, but also reduce the burden of manual inspection and avoid the situation of overflowing dirt and causing a fire.

[0026] Please see Figures 1-3 In this embodiment, the tension / compression sensor 4 is electrically connected to the information processing module 9, and the information processing module 9 is electrically connected to the indicator light 10. A power supply module is located inside the housing 8 on the side of the information processing module 9. A light-transmitting protective cover 19 is fixedly installed at the lower end of the housing 8 on the side of the indicator light 10. The power supply module provides power to the information processing module 9, the tension / compression sensor 4, and the indicator light 10. The housing 8 and the light-transmitting protective cover 19 protect the internal components and reduce the influence of the external environment (they have certain sealing and heat insulation protection functions). The length of the connecting rope 6 is slightly shorter than the height of the oil overflow prevention plate 21, so that when the connecting rope 6 is straightened, the floating ball 7 still has a gap with the oil overflow prevention plate 21, ensuring the normal operation of the tension / compression sensor 4 and controlling the amount of oil collected. The floating ball 7 can rise synchronously with the oil level. The taut connecting rope 6 can pull the connecting plate 5, triggering the tension / compression sensor 4. The tension / compression sensor 4 can transmit information to the information processing module 9, and the information processing module 9 can control the indicator light 10 to light up.

[0027] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, guide plates 20 are fixedly installed on both the left and right sides of the upper end of the oil collecting base plate 13. The locking frame 15 has a U-shaped structure design. An oil collecting anti-overflow plate 21 is provided on the upper side inside the oil collecting box 2. A through groove is opened on the inner side of the oil collecting anti-overflow plate 21. The locking edge 11 is locked and connected to the locking frame 15. The oil collecting anti-overflow plate 21 is locked and connected to the oil collecting box 2. The surface of the locking ball 18 is slidably connected to the movable groove 16. The end of the locking ball 18 away from the spring 17 extends to the outer side of the movable groove 16 and the arc. The grooves 12 are mutually compatible, and the oil collection base plate 13 can cooperate with the guide plate 20 to guide the oil inside the exhaust hood to the oil collection port 14, so that it is concentrated in the oil collection box 2. The spring 17 can drive the locking ball 18 to tightly fit the arc-shaped groove 12. The locking edge 11 can be locked and connected with the locking frame 15. The oil collection box 2 can be pulled out by pulling the box body. The oil collection anti-overflow plate 21 can form an anti-overflow shield for the oil inside, reducing the occurrence of oil spillage in the process. The oil collection anti-overflow plate 21 can also be disassembled and cleaned.

[0028] During operation, the floating ball 7 rises synchronously with the oil level. When the oil level reaches the set range, the taut connecting rope 6 of the floating ball 7 pulls the connecting plate 5, further triggering the tension sensor 4. This allows the information processing module 9 to receive and transmit information, facilitating the control of the indicator light 10 to immediately alert the staff and promptly address the oil collection box 2. The oil collection base plate 13, in conjunction with the guide plate 20, guides the oil inside the exhaust hood to the oil collection port 14, concentrating it in the oil collection box 2. The spring 17 drives the locking ball 18 to tightly fit the arc-shaped groove 12, improving the stability of the locking edge 11 and the locking frame 15. This structure also facilitates the disassembly and installation of the oil collection box 2; simply pull the box to remove it. The oil overflow prevention plate 21 forms an anti-overflow shield for the oil inside, reducing the possibility of oil spillage during the process and improving the ease of cleaning the oil collection box 2.

[0029] Through the above steps, the floating ball 7 rises synchronously with the oil level, and the connecting plate 5 is pulled by the connecting rope 6, triggering the tension and pressure sensor 4. This causes the information processing module 9 to control the indicator light 10 to illuminate, prompting staff to handle the oil collection box 2 in a timely manner. This ensures the accuracy of oil collection status checks, reduces the burden of manual checks, and avoids the situation where spillage occurs, which could lead to a fire. This solves the problem that kitchen ceiling exhaust hoods require frequent manual checks of the oil collection box 2, which is detrimental to the convenience and safety of using the ceiling exhaust hood.
