Description

Technical Field

[0001] The utility model relates to the field of kitchen utensils, in particular to a cleaning device for a range hood. Background Art

[0002] At present, range hoods have been widely used by users to suck cooking fumes during cooking. After long-term use, in order to ensure hygiene and the fume-sucking effect of the range hood, it is necessary to clean the range hood. When cleaning the detachable parts such as the impeller, oil net, oil cup, and smoke baffle of the range hood, it is mostly done by soaking with a cleaning agent mixed with hot water and then manually scrubbing the remaining oil stains. It completely requires manual cleaning, which is time-consuming and laborious. Regarding this cleaning process, there are usually the following deficiencies:

[0003] (1) The hot water required for cleaning needs to be boiled by the user in advance, or the cleaning staff burns it on-site. Boiling water is likely to involve high power, and thus may involve issues of electrical safety;

[0004] (2) As mentioned above, it is usually manual cleaning, which is time-consuming and laborious. The time for cleaning the detachable parts is relatively long, probably more than 1 hour;

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

[0006] (4) The cleaning tools are too scattered, not convenient for storage and management, and are likely to affect the cleaning process and efficiency. Summary of the Utility Model

[0010] A cleaning container having a receiving cavity for receiving a cleaning liquid and a to-be-cleaned part of the range hood;

[0011] A heating assembly installed on the cleaning container for heating the cleaning liquid;

[0012] A driving motor and a stirring member, the stirring member being located in the receiving cavity and below the liquid level of the cleaning liquid, the driving motor being connected to the stirring member and capable of driving the stirring member to rotate; the driving motor can switch between forward rotation and reverse rotation;

[0013] Wherein, the cleaning process of the cleaning device for the to-be-cleaned part includes a first cleaning stage and a second cleaning stage;

[0014] In the first cleaning stage, the heating component is in an operating state to heat the cleaning liquid;

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

[0016] The drive motor is configured to be in a starting state in the second cleaning stage.

[0017] In this solution, through the cooperation of the drive motor and the stirring member, the switching of the drive motor between forward rotation and reverse rotation can achieve the clockwise rotation and counterclockwise rotation of the stirring member, so as to realize the automatic cleaning of the part to be cleaned, which is beneficial to improving the cleaning efficiency and can ensure a better cleaning effect. In addition, the heating of the cleaning liquid can be conveniently realized through the heating component without the need to rely on other auxiliary equipment for heating, and the centralization degree of this cleaning device is relatively high.

[0018] Preferably, the stirring member is an impeller.

[0019] In this solution, with the above structural arrangement, the structure of the stirring member is simple, which is beneficial to simplifying the structure of the cleaning device. In addition, it is also convenient to install the stirring member and the drive motor.

[0020] Preferably, the stirring member is detachably connected to the drive motor, and the impeller is the impeller in the part to be cleaned.

[0021] In this solution, using the impeller of the range hood itself as the stirring member, on the one hand, there is no need to additionally set other structures as the stirring member, which is beneficial to further simplifying the structure of the cleaning device and reducing the manufacturing cost; on the other hand, the impeller is also cleaned during the rotation process and can achieve a better cleaning effect. Usually, there is no need to occupy the cleaning space in the accommodation cavity again, reducing the space requirement for the cleaning container, and at the same time, it is beneficial to clean other parts to be cleaned and ensure the cleaning effect of other parts to be cleaned.

[0022] Preferably, the cleaning container has a barrel body and a cover body. The barrel body is an open structure and has the accommodation cavity, and the cover body is removably covered on the top of the barrel body to open or close the opening of the barrel body;

[0023] The drive motor is installed on the cover body, and the output shaft of the drive motor for connecting the impeller extends into the accommodation cavity.

[0024] In this solution, with the above structure, on the one hand, the cover body can protect the cleaning environment inside the barrel body and prevent it from being affected by the external environment; on the other hand, the cover body can provide an installation carrier for the driving motor, facilitating the installation of the driving motor and not occupying the internal space of the barrel body.

[0025] Preferably, two operating handles are provided on the cover body, and the two operating handles are arranged opposite to each other;

[0026] And / or, a water inlet is provided on the cover body, and a water outlet is provided on the side wall of the barrel body. Both the water inlet and the water outlet can communicate with the accommodating cavity.

[0027] In this solution, the operating handles facilitate the cleaner to pick up and place the cover body, which is convenient to use and helps to further improve the cleaning efficiency.

[0028] Preferably, the cleaning device further includes a temperature detection device and a first controller;

[0029] 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 detecting that the temperature of the liquid to be cleaned reaches a first preset temperature, transmit a first temperature signal to the first controller;

[0030] The first controller is used to receive the first temperature signal and, when receiving the first temperature signal, switch the heating component to a non-working state.

[0031] In this solution, the temperature of the liquid to be cleaned can be known timely and conveniently through the temperature detection device. Through the cooperation of the temperature detection device and the first controller, the liquid to be cleaned can be reliably heated to the first preset temperature. At the same time, when the temperature of the liquid to be cleaned reaches the first preset temperature, the heating component can be stopped heating in time, thereby preventing the temperature of the liquid to be cleaned from being too high, saving energy and avoiding the occurrence of accelerated corrosion caused by too high temperature, which is beneficial to protecting the parts to be cleaned.

[0032] Preferably, the temperature detection device is further used to transmit a second temperature signal to the first controller when detecting that the temperature of the liquid to be cleaned drops to a second preset temperature;

[0033] The first controller is used to receive the second temperature signal and, when receiving the second temperature signal, switch the heating component to a working state;

[0034] Wherein, the first preset temperature is greater than the second preset temperature.

[0035] In this solution, through the cooperation of the temperature detection device and the first controller, it is also possible to timely learn when the temperature drops to the second preset temperature, and it is possible to timely make the heating component perform the heating operation again, so that the cleaning liquid is always within a more suitable temperature range, which can not only avoid the accelerated corrosion caused by too high temperature, but also ensure the cleaning effect.

[0036] Preferably, the heating component includes a heating main body and an electrical connection end. The heating main body is located in the accommodating cavity and is laid at the bottom of the cleaning container.

[0037] The temperature detection device is a thermocouple. The thermocouple includes a detection main body and an electrical connection end. The detection main body is located in the accommodating cavity.

[0038] The electrical connection end of the heating component and the electrical connection end of the thermocouple both extend to the outside of the cleaning container.

[0039] In this solution, the heating main body can be directly placed at the bottom of the cleaning container. Compared with setting the heating main body at a part of the cleaning container, this setting can eliminate the need for a fixing structure, which is beneficial to further simplify the structure of the cleaning device. In addition, setting the electrical connection ends of the heating component and the thermocouple to extend to the outside of the cleaning container is beneficial to realizing the electrical connection between the heating component and the thermocouple and the outside, and is also beneficial to ensuring safety.

[0040] Preferably, the drive motor is also configured to be in a starting state during the first cleaning stage.

[0041] And / or, the cleaning device further includes a movable trolley, and the cleaning container is arranged on the movable trolley.

[0042] In this solution, with the above structural setting, the drive motor is in a starting state during the process of the heating component heating the cleaning liquid. The rotation of the drive motor drives the stirring member to rotate, which can stir the liquid in the cleaning container, is beneficial to strengthening heat transfer, shortening the heating time, and making the heating more uniform, which is beneficial to further improving the cleaning efficiency and also beneficial to ensuring the cleaning effect. In addition, the setting of the movable trolley can more conveniently move the cleaning container to the preset position, saving time and effort, and having strong flexibility in use.

[0043] Preferably, the drive motor is configured to switch to a non-starting state after the working time of the cleaning device reaches the preset cleaning duration.

[0044] The cleaning device further includes a buzzer, and the buzzer is configured to be in a working state after the working time of the cleaning device reaches the preset cleaning duration.

[0045] In this solution, with the above structure set, after the preset cleaning duration is reached, the driving motor stops working and the automatic cleaning ends. This helps prevent the phenomenon that the coating of the range hood is easily corroded due to the excessive soaking time of the part to be cleaned in the cleaning liquid, thus further protecting the part to be cleaned. In addition, the buzzer can work after the preset cleaning duration is reached, so as to remind the cleaner to take out the part to be cleaned in the cleaning container in time. Therefore, even if the cleaner goes to clean non-detachable parts such as the smoke collecting cavity, volute, and surface of the range hood during the automatic cleaning of the part to be cleaned by the cleaning device, there is no need to worry about not being able to take out the part to be cleaned in time after the preset cleaning duration is reached.

[0046] The positive and progressive effects of the present utility model are as follows:

[0047] In this cleaning device, through the cooperation of the driving motor and the stirring member, the driving motor can switch between forward rotation and reverse rotation, enabling the stirring member to rotate clockwise and counterclockwise, thus realizing the automatic cleaning of the part to be cleaned, which is beneficial to improving the cleaning efficiency and can ensure a better cleaning effect. In addition, the heating component can relatively easily heat the cleaning liquid without the need to rely on other auxiliary equipment for heating, and the centralization degree of this cleaning device is relatively high.

[0075] The following gives a preferred embodiment and, in conjunction with the accompanying drawings, more clearly and completely describes the present utility model.

[0076] As Figures 1 to 6As shown in the figure, this embodiment provides a cleaning device for a range hood. The cleaning device includes a cleaning container 10, a heating component 20, a driving motor 30, and a stirring member 40. Among them, the cleaning container 10 has a receiving cavity 101 for receiving the cleaning liquid and the parts to be cleaned of the range hood; the heating component 20 is installed on the cleaning container 10 for heating the cleaning liquid; the stirring member 40 is located in the receiving cavity 101 and below the liquid level of the cleaning liquid, and the driving motor 30 is connected to the stirring member 40 and can drive the stirring member 40 to rotate; the driving motor 30 can switch between forward rotation and reverse rotation. The cleaning process of the cleaning device for the parts to be cleaned includes a first cleaning stage and a second cleaning stage. In the first cleaning stage, the heating component 20 is in a working state to heat the cleaning liquid. In the second cleaning stage, the parts to be cleaned are cleaned. The driving motor 30 is configured to be in a starting state in the second cleaning stage.

[0077] In this embodiment, through the cooperation of the driving motor 30 and the stirring member 40, the driving motor 30 switches between forward rotation and reverse rotation, which can realize the clockwise rotation and counterclockwise rotation of the stirring member 40, thereby realizing the automatic cleaning of the parts to be cleaned, which is beneficial to improving the cleaning efficiency and can ensure a better cleaning effect. In addition, through the heating component 20, it is relatively convenient to heat the cleaning liquid without the need to rely on other auxiliary equipment for heating, and the centralization degree of this cleaning device is relatively high.

[0078] It should be noted that the parts to be cleaned of the range hood mainly refer to the detachable parts of the range hood, such as Figure 5 and Figure 6 the oil cup 70, the oil screen 80, and the smoke baffle 90 shown in the figure.

[0079] In a preferred setting method, the driving motor 30 is further configured to be in a starting state in the first cleaning stage. With this setting, the driving motor 30 is in a starting state during the process of the heating component 20 heating the cleaning liquid. The rotation of the driving motor 30 drives the stirring member 40 to rotate, which can stir the liquid in the cleaning container 10, is beneficial to strengthening heat transfer, shortening the heating time, and making the heating more uniform, thereby being beneficial to further improving the cleaning efficiency and also beneficial to ensuring the cleaning effect.

[0080] As an example, in the first cleaning stage, the driving motor 30 can operate with reference to the following parameters: the frequency is 60 r / min, and it reverses for 10 s after every 10 s of forward rotation, and so on until the first cleaning stage is completed and the cleaning liquid is heated to a preset temperature.

[0081] Correspondingly, in the second cleaning stage, the driving motor 30 can still be set with reference to the above parameters, the frequency is 60 r / min, and it reverses for 10 s after every 10 s of forward rotation, and so on until the second cleaning stage is completed.

[0082] Specifically in this embodiment, as Figures 3 to 6 shown, the stirring member 40 is an impeller. Setting the stirring member 40 as an impeller has a simple structure and is beneficial to simplifying the structure of the cleaning device. In addition, it is also convenient to install the stirring member 40 and the drive motor 30.

[0083] As a preferred setting method, the stirring member 40 is detachably connected to the drive motor 30, and the impeller is the impeller in the item to be cleaned.

[0084] With this setting, using the impeller of the range hood itself as the stirring member 40, on the one hand, there is no need to additionally set other structures as the stirring member 40, which is beneficial to further simplifying the structure of the cleaning device and reducing the manufacturing cost; on the other hand, the impeller is also cleaned while rotating, and a better cleaning effect can be achieved. Usually, there is no need to occupy the cleaning space in the accommodation cavity 101 again, reducing the space requirement for the cleaning container 10, and at the same time, it is beneficial to clean other items to be cleaned and ensure the cleaning effect of other items to be cleaned.

[0085] As Figures 1 to 6 shown, the cleaning container has a barrel body and a cover body 103. The barrel body is an open structure and has an accommodation cavity 101. The cover body 103 is removably covered on the top of the barrel body to open or close the opening of the barrel body. The drive motor 30 is installed on the cover body 103, and the output shaft of the drive motor 30 for connecting the impeller extends into the accommodation cavity 101. With this setting, on the one hand, the cover body 103 can protect the cleaning environment inside the barrel body and prevent it from being affected by the external environment; on the other hand, the cover body 103 can provide an installation carrier for the drive motor 30, facilitating the installation of the drive motor 30 and not occupying the internal space of the barrel body.

[0086] Furthermore, as Figure 1 、 Figure 2 、 Figures 4 to 6 shown, two operation handles 104 are provided on the cover body 103, and the two operation handles 104 are arranged oppositely. The operation handles 104 are convenient for the cleaner to pick up and place the cover body 103, which is convenient to use and is beneficial to further improving the cleaning efficiency. Optionally or alternatively, a water inlet 105 is provided on the cover body 103, and a water outlet 106 is provided on the side wall of the barrel body. Both the water inlet 105 and the water outlet 106 can communicate with the accommodation cavity 101. Among them, the setting of the water inlet 105 is convenient for introducing the cleaning liquid into the accommodation cavity 101, and the setting of the water outlet 106 is convenient for timely discharging the cleaning liquid after cleaning, making it more convenient to use.

[0087] It should be noted that in other alternative embodiments, according to actual needs, only one operation handle 104 may also be provided.

[0088] Furthermore, the cleaning device further includes a temperature detection device and a first controller. The temperature detection device is electrically connected to the first controller. The temperature detection device is configured to detect the temperature of the cleaning liquid to be cleaned, and is configured to transmit a first temperature signal to the first controller when the temperature of the cleaning liquid to be cleaned reaches a first preset temperature. The first controller is configured to receive the first temperature signal, and is configured to switch the heating assembly 20 to a non-operating state when receiving the first temperature signal.

[0089] Among them, the temperature of the cleaning liquid to be cleaned can be timely and conveniently obtained through the temperature detection device. Through the cooperation of the temperature detection device and the first controller, the cleaning liquid to be cleaned can be reliably heated to the first preset temperature. At the same time, when the temperature of the cleaning liquid to be cleaned reaches the first preset temperature, the heating of the heating assembly 20 can be stopped in time, so as to prevent the temperature of the cleaning liquid to be cleaned from being too high, which can not only save energy, but also avoid the occurrence of accelerated corrosion caused by too high temperature, which is beneficial to protecting the parts to be cleaned.

[0090] It should be noted that when cleaning the parts to be cleaned of the range hood, alkali is usually added to the heated cleaning liquid. During the dissolution process of the alkali, heat is released, which further increases the temperature of the cleaning liquid. If the temperature of the cleaning liquid is relatively high before adding the alkali, the temperature of the cleaning liquid is very likely to be too high after adding the alkali, which is easy to accelerate corrosion and then damage the parts to be cleaned. As a preferred setting, the first preset temperature can be set to 62 °C.

[0091] Correspondingly, the temperature detection device is further configured to transmit a second temperature signal to the first controller when detecting that the temperature of the cleaning liquid to be cleaned drops to a second preset temperature. The first controller is configured to receive the second temperature signal, and is configured to switch the heating assembly 20 to an operating state when receiving the second temperature signal. Among them, 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 can also be timely known when the temperature drops to the second preset temperature, and the heating assembly 20 can be made to perform the heating operation again in time, so that the cleaning liquid is always within a more appropriate temperature range, which can not only avoid the occurrence of accelerated corrosion caused by too high temperature, but also ensure the cleaning effect. As a preferred setting, the first preset temperature can be set to 58 °C.

[0093] Such as Figures 3 to 6As shown, the heating assembly 20 includes a heating body 201 and an electrical connection end (hereinafter referred to as the first electrical connection end 202 for convenience of description), the heating body 201 is located in the accommodating cavity 101, and is laid at the bottom of the cleaning container 10. The temperature detection device is a thermocouple 50, and the thermocouple 50 includes a detection body 501 and an electrical connection end (hereinafter referred to as the second electrical connection end 502 for convenience of description), and the detection body 501 is located in the accommodating cavity 101. The first electrical connection end 202 and the second electrical connection end 502 both extend to the outside of the cleaning container 10. Among them, the heating body 201 can be directly placed at the bottom of the cleaning container 10. Compared with setting the heating body 201 at the position of the cleaning container 10, this setting can be set without the need for a fixed structure, which is conducive to further simplifying the structure of the cleaning device. In addition, the electrical connection end of the heating assembly 20 and the electrical connection end of the thermocouple 50 are set to extend to the outside of the cleaning container 10, which is conducive to realizing the electrical connection between the heating assembly 20 and the thermocouple 50 and the outside, and is also conducive to ensuring safety.

[0094] Further, the driving motor 30 is configured to switch to a non-starting state after the working time of the cleaning device reaches a preset cleaning time. The cleaning device also includes a buzzer, which is configured to be in a working state after the working time of the cleaning device reaches a preset cleaning time.

[0095] With such a configuration, after the preset cleaning time is reached, the driving motor 30 stops working and the automatic cleaning ends, which is helpful to prevent the occurrence of the phenomenon that the coating of the range hood is easily corroded due to the long soaking time of the parts to be cleaned in the cleaning liquid, thereby further protecting the parts to be cleaned. In addition, the buzzer can work after the preset cleaning time is reached, so as to remind the cleaner to take out the parts to be cleaned in the cleaning container 10 in time. Therefore, even if the cleaner cleans the non-disassembly and cleaning parts such as the smoke collecting chamber, the volute, and the surface of the range hood during the period when the cleaning device automatically cleans the parts to be cleaned, there is no need to worry about not being able to take out the parts to be cleaned in time after the preset cleaning time is reached.

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

[0097] like Figures 1 to 4 As shown, the cleaning device also includes a movable cart 60, and the cleaning container 10 is arranged on the movable cart 60. Through the arrangement of the movable cart 60, the cleaning container 10 can be moved to a preset position more conveniently, saving time and effort, and having greater flexibility in use. Specifically in this embodiment, the movable cart 60 is moved by the running wheels 601 at the bottom, and as a preferred arrangement, climbing wheels can be used.

[0098] In summary, in this cleaning device, through the cooperation of the driving motor 30 and the stirring member 40, the driving motor 30 can be switched between forward rotation and reverse rotation, enabling the stirring member 40 to rotate clockwise and counterclockwise, thereby realizing the automatic cleaning of the workpiece to be cleaned, which is beneficial to improving the cleaning efficiency and ensuring a better cleaning effect. In addition, the heating assembly 20 can more conveniently heat the cleaning liquid without the need to rely on other auxiliary equipment for heating, and the centralization degree of this cleaning device is relatively high. After testing, using this cleaning device for automatic cleaning can remove more than 95% of the oil stains. After the automatic cleaning is completed, according to actual needs, the remaining stubborn oil stains can be manually scrubbed.

[0099] The following briefly describes the process of using this cleaning device to clean the range hood:

[0100] (1) The cleaner pushes the cleaning container 10 to the preset position through the movable trolley 60 and injects clean water into the barrel body 102 through the water inlet 105.

[0101] (2) Turn on the heating assembly 20, such as a heating rod.

[0102] (3) Remove the workpiece to be cleaned from the range hood.

[0103] (4) Place the detachable parts such as the oil cup 70, the air inlet ring, and the oil net 80 into the accommodating cavity 101 of the cleaning container 10, and install the impeller of the range hood on the driving motor 30.

[0104] (5) Start the motor and run the motor at a frequency of 10 s of forward rotation, 10 s of reverse rotation, and 60 r / min, and use the flow characteristics of the range hood impeller itself to stir the water flow in the cleaning container 10 to strengthen heat transfer and shorten the heating time.

[0105] (6) When the water in the cleaning container 10 is heated to the set temperature (preferably 60 °C), pour in the oil stain cleaning agent, set the cleaning time (preferably 20 min), and start the automatic cleaning mode; during the cleaning process, the driving motor 30 drives the impeller to run at a frequency of 10 s of forward rotation, 10 s of reverse rotation, and 60 r / min, stirring to generate water flow to wash the workpiece to be cleaned in the cleaning container 10; during this period, the heater maintains the temperature in the water tank, for example, 60 ± 2 °C. When the thermocouple 50 detects that the water temperature is lower than 58 °C, the heating rod starts to work, and when it is higher than 62 °C, the heating rod stops working. Among them, during the automatic cleaning, the cleaner can clean the non-detachable parts such as the smoke collecting cavity, the volute, and the surface of the range hood.

[0106] In summary, the cleaning device in this embodiment has at least the following advantages:

[0107] (1) It can realize the automatic cleaning of the detachable parts of the range hood, reduce the workload of manual cleaning, and thus save cleaning time.

[0108] (2) It comes with a heating system that achieves convective heat transfer through the agitation of the impeller, capable of saving the water heating time;

[0109] (3) Through the agitation of the impeller, the cleaning agent for cleaning can be quickly dissolved and diffused, avoiding excessive local concentration and corrosion of the coating;

[0110] (4) The water temperature is controllable. During the cleaning process, it can be heated to maintain the required temperature, and the cleaning time is controllable, avoiding long-term immersion and corrosion of the coating; correspondingly, it is also conducive to achieving standardized cleaning.

[0111] In addition, it should be noted that in the preferred setting mode, this cleaning device also comes with an air switch and leakage protection, which can avoid accidents in case of overload or leakage.

[0112] Although the specific implementation manners of the present utility model have been described above, those skilled in the art should understand that this is only an example. The protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present utility model.
