Description

Technical Field

[0001] This utility model relates to the field of kitchenware, and in particular to a cleaning device for range hoods. Background Technology

[0002] Range hoods are now widely used to remove cooking fumes. After prolonged use, they need to be cleaned to ensure hygiene and maintain their effectiveness. Cleaning detachable parts such as the impeller, grease filter, grease cup, and baffle plate typically involves soaking them in hot water with detergent, followed by manual scrubbing to remove residual grease. This method is entirely manual, time-consuming, and labor-intensive. This cleaning process generally has the following drawbacks:

[0003] (1) The hot water required for cleaning needs to be boiled by the user in advance, or the cleaning personnel can boil it on-site. Boiling water may involve high power, which may lead to electrical safety issues.

[0004] (2) As above, it is usually done manually, which is time-consuming and labor-intensive. The time required to clean the detachable parts is relatively long, about 1 hour or more.

[0005] (3) The soaking time during cleaning needs to be controlled manually. If the soaking time is too long, it will easily corrode the coating of the range hood.

[0006] (4) The cleaning tools are too scattered, making them inconvenient to store and manage, which can easily affect the cleaning process and cleaning efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the defect of low cleaning efficiency in the existing technology of range hood cleaning, and to provide a cleaning device for range hood.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A cleaning device for a range hood, the cleaning device comprising:

[0010] A cleaning container with a receiving cavity for holding cleaning fluid and the parts of a range hood to be cleaned;

[0011] An ultrasonic cleaning assembly is installed in the cleaning container and configured to clean the workpiece to be cleaned by ultrasonic waves.

[0012] A heating element, installed in the cleaning container, is used to heat the cleaning solution;

[0013] The cleaning process of the cleaning device for the part to be cleaned includes a first cleaning stage and a second cleaning stage.

[0014] During the first cleaning stage, the heating component is in operation to heat the cleaning fluid;

[0015] In the second cleaning stage, the part to be cleaned is cleaned;

[0016] The ultrasonic cleaning assembly is configured to be in an activated state during the second cleaning phase.

[0017] In this solution, an ultrasonic cleaning component is incorporated. The cavitation, acceleration, and direct flow effects of ultrasound in the liquid directly and indirectly act on the liquid and contaminants, dispersing, emulsifying, and peeling off the contaminant layer. Combined with a specific cleaning temperature and a specially designed cleaning agent, this reduces or eliminates the need for manual cleaning of grease deposits. This facilitates automated cleaning of the parts, improves cleaning efficiency, and ensures optimal cleaning results. Furthermore, the heating component allows for convenient heating of the cleaning solution without the need for other auxiliary equipment, resulting in a high degree of centralization in the cleaning device. Additionally, the ultrasonic cleaning component requires a lower heating temperature for the cleaning solution, reducing the demands on the heating components, such as heating power and / or heating time.

[0018] Preferably, the ultrasonic cleaning assembly includes a plurality of ultrasonic cleaning heads spaced apart, the plurality of ultrasonic cleaning heads being mounted at the bottom of the cleaning container, and the output ends of the plurality of ultrasonic cleaning heads being located within the receiving cavity.

[0019] In this design, the ultrasonic cleaning head is installed at the bottom of the cleaning container, minimizing its space occupation and thus minimizing interference with the cleaning of the parts to be cleaned. Furthermore, using multiple ultrasonic cleaning heads increases the cleaning range, thereby improving cleaning efficiency and effectiveness.

[0020] Preferably, the cleaning container has a barrel body and a lid, the barrel body has an open structure and has the receiving cavity, and the lid is removably disposed on top of the barrel body to open or close the opening of the barrel body.

[0021] In this solution, the above-mentioned structural design allows the cover to protect the cleaning environment inside the bucket body and prevent it from being affected by the external environment.

[0022] Preferably, the cleaning container is made of a sound-absorbing material.

[0023] In this solution, the above-mentioned structural design can effectively isolate the noise generated by vibration and other factors during the operation of the ultrasonic cleaning component, thereby helping to reduce noise.

[0024] Preferably, the cover is provided with two operating handles, which are arranged opposite to each other;

[0025] And / or, the cover is provided with a water inlet, and the side wall of the barrel body is provided with a water outlet, both of which can communicate with the receiving cavity.

[0026] In this design, the operating handle makes it easy for the cleaner to pick up and put down the cover, which is convenient and helps to further improve cleaning efficiency.

[0027] Preferably, the cleaning device further includes a temperature detection device and a first controller;

[0028] The temperature detection device is electrically connected to the first controller. The temperature detection device is used to detect the temperature of the liquid to be cleaned, and when the temperature of the liquid to be cleaned is detected to reach a first preset temperature, it transmits a first temperature signal to the first controller.

[0029] The first controller is used to receive the first temperature signal and to switch the heating component to a non-operating state when the first temperature signal is received.

[0030] In this solution, the temperature of the cleaning fluid can be obtained promptly and conveniently through a temperature detection device. The cooperation between the temperature detection device and the first controller ensures that the cleaning fluid can be reliably heated to the first preset temperature. Simultaneously, once the temperature of the cleaning fluid reaches the first preset temperature, the heating element can be stopped in a timely manner, preventing the temperature of the cleaning fluid from becoming too high. This saves energy and avoids accelerated corrosion caused by excessive temperature, thus protecting the parts to be cleaned.

[0031] Preferably, the temperature detection device is further configured to transmit a second temperature signal to the first controller when the temperature of the liquid to be cleaned is detected to drop to a second preset temperature;

[0032] The first controller is used to receive the second temperature signal and to switch the heating component to the working state when the second temperature signal is received;

[0033] The first preset temperature is greater than the second preset temperature.

[0034] In this solution, the temperature detection device and the first controller work together to detect when the temperature drops to the second preset temperature and enable the heating component to reheat in time, so that the cleaning fluid is always within a suitable temperature range. This can prevent accelerated corrosion caused by excessive temperature and ensure the cleaning effect.

[0035] Preferably, the heating assembly includes a heating body and an electrical connection terminal, the heating body being located within the receiving cavity and laid at the bottom of the cleaning container;

[0036] The temperature detection device is a thermocouple, which includes a detection body and an electrical connection terminal, and the detection body is located inside the receiving cavity;

[0037] The electrical connection terminals of the heating assembly and the thermocouple both extend to the outside of the cleaning container.

[0038] In this design, the heating element can be placed directly at the bottom of the cleaning container. Compared to placing the heating element in the middle of the cleaning container, this arrangement eliminates the need for a fixed structure, thus further simplifying the structure of the cleaning device. Furthermore, extending the electrical connection terminals of the heating element and the thermocouple to the outside of the cleaning container facilitates electrical connections between the heating element and the thermocouple and the external environment, while also ensuring safety.

[0039] Preferably, the cleaning device further includes a movable trolley, on which the cleaning container is disposed.

[0040] In this solution, the movable trolley allows for easy movement of the cleaning container to a preset location, saving time and effort and offering greater flexibility in use.

[0041] Preferably, the ultrasonic cleaning component is configured to switch to a non-starting state after the working time of the cleaning device reaches a preset cleaning duration;

[0042] The cleaning device also includes a buzzer, which is configured to operate after the working time of the cleaning device reaches a preset cleaning duration.

[0043] In this solution, the aforementioned structural configuration ensures that the ultrasonic cleaning component stops operating and the automatic cleaning process ends after the preset cleaning time is reached. This helps prevent corrosion of the range hood's coating due to prolonged immersion of the parts in the cleaning solution, thus further protecting the parts. Additionally, a buzzer activates after the preset cleaning time is reached, reminding the user to remove the parts from the cleaning container promptly. Therefore, even if the user cleans non-disassembly parts of the range hood, such as the smoke collection chamber, volute, or surface, while the cleaning device is automatically cleaning the parts, there is no need to worry about not being able to remove them in time after the preset cleaning time has elapsed.

[0044] The positive and progressive effects of this utility model are as follows:

[0045] This cleaning device utilizes an ultrasonic cleaning component. The cavitation, acceleration, and direct flow effects of ultrasound waves in the liquid directly and indirectly act on the liquid and contaminants, dispersing, emulsifying, and peeling off the contaminant layer. Combined with a specific cleaning temperature and a specially designed cleaning agent, this reduces or eliminates the need for manual cleaning of grease and grime, facilitating automated cleaning of the workpieces, improving cleaning efficiency, and ensuring optimal cleaning results. Furthermore, the heating component allows for convenient heating of the cleaning fluid without the need for other auxiliary equipment, resulting in a high degree of centralization in the cleaning device. Additionally, the ultrasonic cleaning component requires a lower heating temperature for the cleaning fluid, reducing the demands on the heating element, such as heating power and / or heating time.

[0075] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0076] like Figures 1 to 7 As shown, this embodiment provides a cleaning device for a range hood, which includes a cleaning container 10, an ultrasonic cleaning assembly 30, and a heating assembly 20. The cleaning container 10 has a receiving cavity 101 for holding cleaning fluid and the components of the range hood to be cleaned. The ultrasonic cleaning assembly 30 is installed in the cleaning container 10 and configured to clean the components using ultrasonic waves. The heating assembly 20 is installed in the cleaning container 10 and is used to heat the cleaning fluid. The cleaning process of the components includes a first cleaning stage and a second cleaning stage. In the first cleaning stage, the heating assembly 20 is in operation to heat the cleaning fluid. In the second cleaning stage, the components are cleaned. The ultrasonic cleaning assembly 30 is configured to be in an activated state during the second cleaning stage.

[0077] In this embodiment, by setting up an ultrasonic cleaning component 30, the ultrasonic waves in the liquid are used to directly and indirectly act on the liquid and contaminants through cavitation, acceleration, and direct flow effects. This disperses, emulsifies, and peels off the contaminant layer. Combined with a specific cleaning temperature and a specially designed cleaning agent, this reduces or even eliminates the need for manual cleaning of grease, facilitating automated cleaning of the parts, improving cleaning efficiency, and ensuring optimal cleaning results. Furthermore, the heating component 20 allows for convenient heating of the cleaning fluid without the need for other auxiliary equipment, resulting in a high degree of centralization in the cleaning device. Additionally, by using ultrasonic waves for ultrasonic cleaning, the required heating temperature of the cleaning fluid is lower, thus reducing the demands on the heating component, such as heating power and / or heating time.

[0078] It should be noted that the parts of the range hood to be cleaned mainly refer to the detachable parts, such as... Figure 3 , Figure 4 , Figure 6 and Figure 7 The oil cup 70, oil mesh 80, impeller 100, and smoke baffle 90 shown are examples of these components.

[0079] like Figure 3 and Figure 4 As shown, the ultrasonic cleaning assembly 30 includes a plurality of ultrasonic cleaning heads 40 spaced apart. The plurality of ultrasonic cleaning heads 40 are installed at the bottom of the cleaning container 10, and the output ends of the plurality of ultrasonic cleaning heads 40 are located inside the receiving cavity 101.

[0080] The ultrasonic cleaning head 40 is installed at the bottom of the cleaning container 10, which minimizes its occupation of other space within the container and thus avoids affecting the cleaning of the parts to be cleaned. Furthermore, using multiple ultrasonic cleaning heads 40 increases the cleaning range of the ultrasonic cleaning process, thereby improving cleaning efficiency and effectiveness.

[0081] As a preferred configuration, in this embodiment, a total of ten ultrasonic cleaning heads 40 are provided, arranged in two opposite rows. Each ultrasonic cleaning head 40 corresponds to an ultrasonic generator. In other alternative embodiments, the ultrasonic cleaning heads 40 can be configured according to actual cleaning requirements, including their number and distribution.

[0082] It should also be noted that the cleaning principle of the ultrasonic cleaning component 30 is the ultrasonic cleaning principle in the existing technology, which will not be elaborated here.

[0083] like Figures 1 to 7As shown, the cleaning container has a barrel body 102 and a lid 103. The barrel body 102 has an open structure and a receiving cavity 101. The lid 103 is removably installed on top of the barrel body 102 to open or close the opening of the barrel body 102. With this configuration, the lid 103 can protect the cleaning environment inside the barrel body 102 from the influence of the external environment.

[0084] As a preferred configuration, the cleaning container 10 is made of a sound-absorbing material. This configuration effectively isolates the noise generated by vibration and other factors during the operation of the ultrasonic cleaning assembly 30, thereby helping to reduce noise.

[0085] The specific material of the cleaning container 10 is not limited, as long as it is a sound-absorbing material suitable for this purpose.

[0086] Furthermore, such as Figure 1 , Figure 2 , Figures 5 to 7 As shown, two operating handles 104 are provided on the lid 103, and the two operating handles 104 are arranged opposite each other. The operating handles 104 facilitate the user in taking and putting on the lid 103, making it convenient to use and helping to further improve cleaning efficiency. Optionally or alternatively, the lid 103 is provided with a water inlet 105, and the side wall of the barrel body 102 is provided with a water outlet 106. Both the water inlet 105 and the water outlet 106 can communicate with the receiving cavity 101. The water inlet 105 facilitates the introduction of cleaning fluid into the receiving cavity 101, and the water outlet 106 facilitates the timely discharge of cleaning fluid after cleaning, making it more convenient to use.

[0087] It should be noted that in other alternative implementations, only one operating handle 104 may be provided, depending on actual needs.

[0088] Furthermore, the cleaning device also includes a temperature detection device and a first controller. The temperature detection device is electrically connected to the first controller and is used to detect the temperature of the cleaning liquid. When the temperature of the cleaning liquid reaches a first preset temperature, the temperature detection device transmits a first temperature signal to the first controller. The first controller receives the first temperature signal and, upon receiving the first temperature signal, switches the heating component 20 to a non-operating state.

[0089] The temperature detection device allows for timely and convenient monitoring of the temperature of the cleaning solution. The coordination between the temperature detection device and the first controller ensures that the cleaning solution is reliably heated to the first preset temperature. Simultaneously, once the cleaning solution reaches the first preset temperature, the heating element 20 promptly stops heating, preventing the solution from overheating. This saves energy and avoids accelerated corrosion caused by excessive temperature, thus protecting the parts being cleaned.

[0090] It should be noted that when cleaning the components of a range hood, alkali is usually added to the heated cleaning solution. The alkali releases heat during dissolution, further raising the temperature of the cleaning solution. If the cleaning solution is already hot before adding the alkali, the temperature after adding the alkali may become excessively high, potentially accelerating corrosion and damaging the components. As a preferred setting, the first preset temperature can be set to 50℃.

[0091] Accordingly, the temperature detection device is also used to transmit a second temperature signal to the first controller when it detects that the temperature of the cleaning liquid has dropped to a second preset temperature. The first controller is used to receive the second temperature signal and to switch the heating component 20 to the working state when it receives the second temperature signal. The first preset temperature is greater than the second preset temperature.

[0092] Here, through the cooperation of the temperature detection device and the first controller, it is possible to promptly detect when the temperature drops to the second preset temperature and to immediately trigger the heating component 20 to resume heating, ensuring that the cleaning fluid remains within a suitable temperature range. This avoids accelerated corrosion due to excessively high temperatures while maintaining the cleaning effect. Preferably, the second preset temperature can be set to 48℃.

[0093] like Figures 3 to 7 As shown, the heating assembly 20 includes a heating body 201 and an electrical connection terminal (hereinafter referred to as the first electrical connection terminal 202 for ease of description). The heating body 201 is located inside the receiving cavity 101 and is laid at the bottom of the cleaning container 10. The temperature detection device is a thermocouple 50, which includes a detection body 501 and an electrical connection terminal (hereinafter referred to as the second electrical connection terminal 502 for ease of description). The detection body 501 is located inside the receiving cavity 101. Both the first electrical connection terminal 202 and the second electrical connection terminal 502 extend to the outside of the cleaning container 10. The heating body 201 can be directly placed at the bottom of the cleaning container 10. Compared to placing the heating body 201 in other parts of the cleaning container 10, this arrangement eliminates the need for a fixed structure, thus further simplifying the structure of the cleaning device. Furthermore, setting the electrical connection terminals of the heating assembly 20 and the thermocouple 50 to extend to the outside of the cleaning container 10 facilitates electrical connection between the heating assembly 20 and the thermocouple 50 and the outside, and also helps ensure safety.

[0094] Furthermore, the ultrasonic cleaning component 30 is configured to switch to a non-start state after the cleaning device has operated for a preset cleaning duration. The cleaning device also includes a buzzer, which is configured to activate after the cleaning device has operated for the preset cleaning duration.

[0095] This setup ensures that the drive motor 30 stops working after the preset cleaning time is reached, automatically ending the cleaning process. This helps prevent corrosion of the range hood's coating due to prolonged immersion in the cleaning solution, thus further protecting the components. Additionally, a buzzer activates after the preset cleaning time is reached, reminding the user to remove the components from the cleaning container 10. Therefore, even if the user cleans non-disassembly parts of the range hood, such as the smoke collection chamber, volute, or surface, while the cleaning device is automatically cleaning the components, there is no need to worry about not being able to remove them in time after the preset cleaning time has elapsed.

[0096] As an example, the preset cleaning time can be set to 20 minutes.

[0097] like Figures 1 to 5 As shown, the cleaning device also includes a movable trolley 60, on which the cleaning container 10 is mounted. The movable trolley 60 allows for convenient movement of the cleaning container 10 to a preset position, saving time and effort and offering greater flexibility. Specifically, in this embodiment, the movable trolley 60 is moved using wheels 601 at its bottom; preferably, ramp wheels are used. Furthermore, for ease of carrying and adjustment as needed, the push handle of the movable trolley 60 can be designed as a retractable or foldable structure.

[0098] In summary, in this cleaning device, the cooperation between the drive motor 30 and the agitator 40, and the switching between forward and reverse rotation of the drive motor 30, enables the agitator 40 to rotate clockwise and counterclockwise, thereby achieving automatic cleaning of the items to be cleaned. This improves cleaning efficiency and ensures better cleaning results. Furthermore, the heating component 20 allows for convenient heating of the cleaning solution without the need for other auxiliary equipment, resulting in a high degree of centralization in the cleaning device. Additionally, the ultrasonic cleaning component 30 utilizes ultrasonic waves for ultrasonic cleaning, requiring a lower heating temperature for the cleaning solution, thus reducing the demands on the heating components, such as heating power and / or heating time.

[0099] Tests have shown that this cleaning device can remove more than 95% of oil stains during automatic cleaning. After the automatic cleaning is completed, any remaining stubborn oil stains can be manually scrubbed as needed.

[0100] The following is a brief description of the process of cleaning a range hood using this cleaning device:

[0101] (1) The cleaner pushes the cleaning container 10 to the preset position using the movable trolley 60 and injects clean water into the barrel body 102 through the water inlet 105;

[0102] (2) Turn on the heating component 20, such as the heating rod;

[0103] (3) Remove the parts to be cleaned (including oil cup 70, air inlet ring, oil filter 80, impeller 100, etc.) from the range hood;

[0104] (4) Place the detachable and washable parts such as oil cup 70, air inlet ring, oil screen 80, and impeller 100 into the receiving cavity 101 of the cleaning container 10;

[0105] (5) When the water in the cleaning container 10 is heated to the set temperature (preferably 50°C), the oil stain cleaning agent is poured in, and the cleaning time is set (preferably 20 minutes) to start the automatic cleaning mode; during the cleaning process, the ultrasonic cleaning head vibrates at a fixed frequency (25-40KHz), generating air bubbles and high-energy direct flow into the complex surfaces and hidden gaps of the oil stains in the cleaning container 10. During this period, the heater maintains the temperature in the water tank, for example, 50±2°C. When the thermocouple detects that the water temperature is below 48°C, the heating rod starts to work, and when it is above 52°C, the heating rod stops working. During the automatic cleaning, the cleaner can clean non-disassembly parts such as the smoke collection chamber, volute, and surface of the smoke machine;

[0106] (6) When the cleaning time is over, the buzzer in the cleaning container 10 will sound to remind the service technician to take out the parts to be cleaned in the cleaning container 10 in time and further scrub the remaining residue.

[0107] (7) After wiping away the residual oil stains on the parts to be cleaned, drain the wastewater through the outlet 106, add clean water, and rinse once. During this process, briefly turn on the ultrasonic cleaning head 40 (e.g., 1 minute) to enhance the rinsing effect; after rinsing, wipe off the residual water, reinstall the disassembled parts, and complete the range hood cleaning.

[0108] In summary, the cleaning device in this embodiment has at least the following advantages:

[0109] (1) It can automatically clean the disassembled parts of the range hood, which can reduce the workload of manual cleaning and thus save cleaning time;

[0110] (2) The ultrasonic cleaning component is used to achieve cleaning, which requires a lower heating temperature of the cleaning fluid, thereby reducing the demand on the heating component, such as heating power and / or heating time.

[0111] (3) It has its own heating system, so there is no need to use an extra kettle to boil water, which can save boiling time and simplify cleaning operations;

[0112] (4) The water temperature is controllable. The required temperature can be maintained by heating during the cleaning process, and the cleaning time is controllable, avoiding prolonged immersion and corrosion of the coating. Correspondingly, it is also conducive to achieving standardized cleaning. In addition, it should be noted that in the preferred configuration, the cleaning device is also equipped with an air switch and leakage protection, which can prevent accidents in the event of overload or leakage.
