Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a cooking device with a cleaning function and a control method thereof. Background Art

[0002] With economic development, users have increasingly high expectations for clean and healthy food. After cooking, some residual water remains in the water system and evaporator of cooking equipment. If the cooking equipment is not used for a long time, this residual water can breed bacteria and be used the next time you cook, resulting in an unclean cooking environment and affecting user health. The current common solution is to pump the wastewater back into a wastewater box using a water pump. The user then removes the wastewater box and pours it out. This solution requires the addition of an additional water pump, which increases costs; it also requires users to pour out the wastewater themselves, impacting the user experience.

[0003] After cooking food, cooking equipment often leaves a lot of oil residue. Due to the inner structure of the cooking equipment, it is difficult to clean the cavity.

[0056] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0057] Example 1:

[0058] See also Figure 1 and Figure 2 As shown, a cooking device with a cleaning function includes a cooking device body 1, a water inlet pipe 2, a drain pipe 3, a controller (not shown) and a cleaning assembly 4. The water inlet pipe 2 runs through the cooking device body 1 and is connected to the cleaning assembly 4 when the interior of the cooking device needs to be cleaned. The cleaning assembly 4 is arranged inside the cooking device body 1 to clean the interior of the cooking device body 1. The drain pipe 3 is connected to the cooking device body 1 and is used to discharge residual clean water from the drain pipe 3, thereby reducing the accumulation of residual water and creating a cleaner and more sanitary environment.

[0059] Specifically, the cooking device body 1 referred to in the present invention can be a general term for devices used for steam cooking, such as a steam box, a steam oven, a microwave steam box, and a microwave steam oven.

[0060] The water inlet pipe 2 and the drain pipe 3 are both arranged at the bottom of the cooking device body 1. This increases the space available for the cooking device and is more conducive to draining excess water and cleaning the interior of the cooking device.

[0061] See also Figure 2 As shown, the water inlet pipe 2 is provided with a flow meter 5 for calculating the water flow, a solenoid valve 6 for managing the water flow, and an evaporator 7 for heating the inlet water in sequence in the water inlet direction. The flow meter 5 detects the water flow signal in the water inlet pipe 2 in real time and transmits the detected water flow signal to the controller. The information processing module in the controller processes the water flow signal and calculates the water pressure signal. The controller obtains the power signal of the evaporator 7 and increases or decreases the water pressure signal and the power of the evaporator 7 according to a preset increase or decrease value, thereby controlling the opening of the solenoid valve 6 and the heating power of the evaporator 7 to control the cleaning component 4 to be in the steam cleaning mode or the water cleaning mode.

[0062] Specifically, the water pressure increases by 5 kPa every thirty seconds, and the evaporation element 7 increases by 300 W every thirty seconds; when the water pressure increases to a critical value, the water pressure decreases by 5 kPa every thirty seconds, and the evaporation element 7 decreases by 300 W every thirty seconds;

[0063] See also Figure 2 As shown, when the heating power of the evaporator 7 is high, a high-temperature steam cleaning mode is used. When the water in the water inlet pipe 2 flows through the evaporator 7, it turns into water vapor, flows into the cleaning component 4, and is sprayed onto the interior of the cooking device body 1 by the cleaning component 4, thereby cleaning more thoroughly and effectively removing grease. When the heating power of the evaporator 7 is low, the water in the water inlet pipe 2 becomes high-temperature water when flowing through the evaporator 7, and cleans the interior of the cooking device where grease is relatively light.

[0064] By adopting the above structure and utilizing the high-temperature steam cleaning mode and the high-temperature water cleaning mode for interactive cleaning, the cleaning is simpler and more thorough, and is conducive to reducing costs.

[0065] Specifically, the evaporation element 7 adopts a thick film evaporator with a heating power of 1200-3000W and is attached to the water inlet pipe, which has a good heating effect and does not take up space.

[0066] See also Figure 3 、 Figure 4 and Figure 7As shown, further, the cleaning component 4 includes a cleaning main pipe 41 and a cleaning auxiliary pipe 42. When not cleaning, the cleaning auxiliary pipe 42 is arranged in the cleaning main pipe 41 and forms an integral structure with the cleaning main pipe 41; when cleaning, the cleaning auxiliary pipe 42 is subjected to the action of water pressure, so that the cleaning auxiliary pipe 42 can slide relative to the cleaning main pipe 41. The cleaning main pipe 41 is connected to the water outlet of the water inlet pipe 2, and the cleaning main pipe 41 and the cleaning auxiliary pipe 42 are both provided with a plurality of spray holes 43. During cleaning, due to the action of water pressure, the cleaning main pipe 41 and the cleaning auxiliary pipe 42 begin to make a circular motion around the water inlet pipe 2, and the spray holes 43 open upward. With this structure, various dead corners in the cooking equipment can be cleaned, so that the cleaning effect is better.

[0067] See you Figure 4 and Figure 7 As shown, further, the upper surface and lower surface of the cleaning main pipe 41 each include two obliquely arranged spray holes 43, wherein the spray holes 43 on the upper surface or the lower surface are respectively located at the two ends of the cleaning main pipe 41, and the directions of the spray holes 43 are opposite, that is, the sprayed water or water vapor is located in opposite directions, thereby providing a rotational force for the cleaning main pipe 41, so that the cleaning component 4 can rotate, the cleaning is more thorough, and different parts of the cooking equipment can be cleaned.

[0068] See also Figure 3 As shown, further, the cleaning component 4 includes two cleaning sub-pipes 42, which are respectively arranged at both ends of the cleaning main pipe 41, and can slide relative to the cleaning main pipe 41, and the two cleaning sub-pipes 42 are staggered, which can realize cleaning of different places inside the cooking equipment body 1 and increase the cleaning effect. The two cleaning sub-pipes 42 are staggered mainly to enable the cleaning sub-pipes 42 to be stored in the cleaning main pipe 41, which is convenient for installation and storage.

[0069] See also Figure 3 and Figure 7 As shown, further, the cleaning main pipe 41 includes a water inlet 411 connected to the water inlet pipe 2. The water inlet 411 is connected to the water inlet pipe 2 and is used to guide water or water vapor into the cleaning main pipe 41 or the cleaning auxiliary pipe 42 to complete cleaning.

[0070] See also Figure 7 As shown, further, one end of the cleaning auxiliary pipe 42 facing the water inlet 411 is open, and the other end is closed, so that the cleaning auxiliary pipe 42 can be pushed out by water pressure. According to the size of the water pressure, the different positions of the cleaning auxiliary pipe 42 relative to the cleaning main pipe 41 are adjusted. The greater the water pressure, the greater the distance the cleaning auxiliary pipe 42 is pushed out, and the cleaning is more comprehensive and thorough. The lower the water pressure, the smaller the distance the cleaning auxiliary pipe 42 is pushed out.

[0071] See also Figure 3 As shown, specifically, the cleaning main pipe 41 is provided with 2 inclined spray holes 43 and 8 upward-facing spray holes 43, and the cleaning auxiliary pipe 42 includes 3 spray holes 43, which can achieve cleaning of different places inside the cooking equipment body 1, and the cleaning range is more comprehensive.

[0072] See also Figure 6 and Figure 7 As shown, further, the cleaning assembly 4 also includes an elastic member 44, one end of which is fixed in the cleaning main pipe 41, and the other end is connected to the opening of the cleaning auxiliary pipe 42; specifically, in this embodiment, the elastic member 44 adopts a spring, so that when cleaning is stopped, the cleaning auxiliary pipe 42 can be pulled back into the cleaning main pipe 41 due to the elastic restoring force of the spring, which is convenient for storage, reception and installation.

[0073] See also Figure 3 As shown, further, the water outlet of the water inlet pipe 2 is provided with a catheter cover 8. When cooking is required, the catheter cover 8 is placed on the water outlet of the water inlet pipe 2 to prevent the oil stains in the cooking equipment body 1 or the oil stains of the food from dripping into the water inlet pipe 2 and causing the water inlet pipe 2 to be blocked.

[0074] See also Figure 2 As shown, further, the cooking device body 1 includes a water tank 11 for storing cleaning water and is concave downward. The drain pipe 3 is connected to the water tank 11. The water tank 11 can collect the remaining water inside the cooking device and discharge it through the drain pipe 3.

[0075] See also Figure 1 or Figure 3 As shown, the cooking device body 1 further includes a filter 12, and the filter 12 is covered on the water storage tank 11 to filter solid pollutants to prevent the drain pipe 3 from being blocked.

[0076] See also Figure 2 As shown, further, the drain pipe 3 includes a drain pump 31 for sucking the accumulated water in the water storage tank 11 to improve the treatment of residual water. When cleaning, the drain pump 31 is turned on at the same time to prevent the clean water from remaining and affecting the cleaning effect.

[0077] Furthermore, it also includes a temperature sensor (not shown in the figure), which is arranged inside the cooking device body 1 and connected to the controller. When the temperature sensor senses that the temperature inside the cooking device body 1 is lower than 50°C, it prompts the user to install the cleaning component 4. Specifically, the water inlet 411 in the cleaning component 4 is connected to the water outlet of the water inlet pipe 2, and is used to guide water or water vapor to the cleaning main pipe 41 or the cleaning auxiliary pipe 42 for cleaning.

[0078] Working process:

[0079] When the temperature sensor inside the cooking device body 1 senses that the temperature inside the cooking device body 1 does not exceed 50°C, the conduit cover 8 is removed and the water inlet pipe 2 is connected to the cleaning component 4. At this time, water begins to flow into the water inlet pipe 2 and flows through the flow meter 5, the solenoid valve 6 and the evaporator 7, the cleaning main pipe 41 and the cleaning auxiliary pipe 42 in sequence. The controller receives the water flow signal transmitted by the flow meter 5 and the heating power of the evaporator 7 in real time, and controls the opening of the solenoid valve 6 and the power of the evaporator 7 according to the changed water flow signal and the heating power of the evaporator 7. When the opening of the solenoid valve 6 is changed, the water pressure in the water inlet pipe 2 also changes accordingly. Due to the effect of the water pressure, the position between the cleaning auxiliary pipe 42 and the cleaning main pipe 41 is adjusted. The position of the cleaning auxiliary pipes 42 at both ends is changed so that the cleaning range is gradually moved outward, so that the cleaning range is more comprehensive and the cleaning effect is better. While gradually changing the opening of the solenoid valve 6, the heating power of the evaporator 7 is changed, thereby changing the cleaning mode. The cleaning process can be repeated multiple times. In this embodiment, four interactive cleaning processes are adopted to achieve better cleaning effect. During the cleaning process, water flows into the water storage tank 11, and the drainage pump 31 on the drainage pipe 3 drains the water. When the remaining water in the cooking device is drained, the heating device in the cooking device body 1 is turned on to heat and dry the remaining water. Therefore, when the interior of the cooking device is efficiently cleaned, the remaining water can also be dried to improve the sanitary environment.

[0080] Example 2:

[0081] The general structure of Example 2 is the same as that of Example 1, with the only difference being that the cleaning assembly 4 does not include the elastic member 44, but instead has slideways (not shown in the figure) provided at both ends of the inner wall of the cleaning main pipe 41, and the cleaning auxiliary pipe 42 includes slide rails (not shown in the figure) corresponding to the slideways. Under the action of water pressure, the cleaning auxiliary pipe 42 slides along the slideway on the cleaning main pipe 41, thereby adjusting the cleaning range. With this structure, sliding is simpler and less likely to get stuck. When cleaning is not required, the cleaning auxiliary pipe 42 is manually pushed inward to form an integrated structure with the cleaning main pipe 41.

[0082] Specifically, the cooking device body 1 referred to in the present invention can be a general term for devices used for steam cooking, such as a steam box, a steam oven, a microwave steam box, and a microwave steam oven.

[0083] Example 3:

[0084] A control method for a cooking device with a cleaning function, applied to any of the above items, comprises the following steps:

[0085] See also Figure 8 or Figure 9As shown, S1: Start the cleaning program, use the temperature sensor to detect the temperature value in real time and transmit it to the controller, and the comparison module in the controller determines whether the temperature value is greater than or equal to the preset temperature value. The preset temperature value is 50°C. If the real-time detected temperature value is greater than or equal to the preset temperature value, the solenoid valve and the evaporation element are not started; if the real-time detected temperature value is less than the preset temperature value, the solenoid valve and the evaporation element are started to prevent the temperature inside the cooking device from being too high, which may cause a malfunction of the heating tube, and the cleaning component is installed at this time.

[0086] S2: Detect the water flow signal of the flow meter in real time, and transmit the water flow signal to the controller to monitor the water flow in the water inlet pipe in real time, so as to make the whole system more stable and the cleaning effect more intelligent.

[0087] S3: controlling the water pressure and the heating power of the evaporator according to the water flow signal;

[0088] Furthermore, the method further comprises the following steps:

[0089] See also Figure 9 As shown, S31: the information processing module of the controller calculates a real-time water pressure signal based on the water flow signal. The water pressure signal is calculated by the obtained water flow signal. Specifically, the water pressure is equal to the water flow multiplied by the pipe diameter of the water inlet pipe. Since the pipe diameter adopts a prescribed diameter, the water pressure is determined by the water flow; the magnitude of the real-time water pressure signal and the maximum water pressure signal is determined, wherein the water pressure in the water inlet pipe is 20 kPa for the first time;

[0090] If the real-time water pressure signal is less than the maximum water pressure signal (50KPa), within 30 seconds, the controller controls the water pressure in the water inlet pipe to increase according to an increase value of 5KPa, thereby controlling the change in the opening of the solenoid valve, and the controller controls the evaporation element to increase according to an increase value of 300W, and returns to S2. Specifically, the water pressure increase value is returned to step S2, the water flow signal after the increase is calculated, and the opening of the solenoid valve and the heating power of the evaporation element are controlled, thereby controlling the cleaning mode of the cleaning component; if the real-time water pressure signal is greater than or equal to the maximum water pressure signal (50KPa), the magnitude of the water pressure and the magnitude of the heating power of the evaporation element are controlled.

[0091] See also Figure 9 As shown, S32: within a preset time, controlling the water pressure and the evaporation element power to decrease by a preset reduction value, specifically, the preset reduction value of the water pressure is 5 kPa, and the preset reduction value of the evaporation element heating power is 300 W; and detecting a water flow signal in real time, and transmitting the water flow signal to a controller;

[0092] S33: Calculating a water pressure signal based on the water flow signal, and determining the magnitude of the water pressure signal and the minimum water pressure signal;

[0093] If the water pressure signal is greater than the minimum water pressure signal (20 KPa), the process returns to S32; if the water pressure signal is less than or equal to the minimum water pressure signal (20 KPa), the counting module in the controller counts and adds the values.

[0094] Furthermore, in step S33, the counting module in the controller performs counting and accumulation, and further includes the following steps:

[0095] See also Figure 9 As shown, S34: determine the size of the superimposed counting times of the counting module and the preset counting times (4 times);

[0096] If the count is less than 4 times, return to S31; if the count is greater than or equal to 4 times, close the solenoid valve, evaporator and drain pump. The count represents the number of times the cleaning component is cleaned. The more times it is cleaned, the better the cleaning effect and the stronger the decontamination ability.

[0097] See also Figure 8 As shown, S4: controlling the cleaning component to be in steam cleaning mode or high-temperature water cleaning mode, by changing the heating power of the evaporator, thereby changing the steam cleaning mode and the high-temperature water cleaning mode of the cleaning component, and during the cleaning process, the steam cleaning mode and the high-temperature water cleaning mode work alternately, when the water pressure increases according to a predetermined increase value and the evaporator increases according to a predetermined increase value, the cleaning component gradually changes from the high-temperature water cleaning mode to the steam cleaning mode; when the water pressure decreases according to a predetermined decrease value and the evaporator decreases according to a predetermined decrease value, the cleaning component gradually changes from the steam cleaning mode to the high-temperature water cleaning mode; the entire cleaning process is more efficient and convenient, and the cleaning effect is better.

[0098] When the solenoid valve, evaporation element and drainage pump are closed and the heating device of the cooking device is started, the interior of the cooking device is heated and dried within 10 minutes, and the cleaning procedure is completed.

[0099] Cleaning is performed interactively through high-temperature steam cleaning mode and high-temperature water cleaning mode, and the same cleaning process is cycled four times, which makes the cooking equipment clean more thoroughly and comprehensively.

[0100] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
