Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and particularly relates to a cleaning control method for an integrated stove and an integrated stove. Background Art

[0002] An integrated stove, also known as an environmental protection stove or an integrated environmental protection stove in the industry, is a kitchen appliance that integrates multiple functions such as a range hood, a gas stove, a disinfection cabinet, a steam oven, and a storage cabinet. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption, and environmental protection. After the range hood is used for a period of time, a lot of oil stains and grease will gradually adhere to the impeller and flue. The oil stains will undergo an oxidation reaction to form acidic substances, which will corrode and rust the range hood. The grease can block the oil leakage cover and oil leakage pipe, affecting the normal oil fume filtration and oil drainage of the range hood, causing poor kitchen smoke exhaust. The smoke staying indoors will spread into the dining room or the room close to the kitchen, and the oil stains accumulated on the impeller flue will adhere to other substances in the air, making the exhaust not smooth, increasing the dispersion of oil fume in the kitchen, affecting the indoor air quality, damaging health, and the accumulated oil stains will also increase the load of the range hood, affecting the normal use of the equipment, increasing energy consumption, shortening the service life of the range hood, and even posing a fire hazard.

[0003] The cleaning method for the range hood of the prior art is manual cleaning. When cleaning, the relevant parts of the range hood need to be disassembled from the integrated stove and then manually cleaned with a cleaning agent. This is not only troublesome to operate and has low cleaning efficiency, but also requires certain professional skills to disassemble and assemble the range hood. Therefore, it is difficult for ordinary users to carry out daily cleaning and maintenance. Summary of the Invention

[0028] As Figures 1 to 3 shown, Figure 1 The figure shows a flowchart of a cleaning control method for an integrated range hood provided by the present invention. Figure 2 The figure shows a schematic diagram of the internal structure of an integrated range hood provided by the present invention. Figure 3 The figure shows an exploded view of the internal structure of an integrated range hood provided by the present invention.

[0029] An embodiment of the present invention provides a cleaning control method for an integrated range hood. The integrated range hood includes a controller, a steam cooking system 1 and a range hood system 2. The steam cooking system 1 includes a water tank 11, a first water pump 12, a first evaporator 13 and a steam cooking inner container 14 that are sequentially connected in communication along the direction of liquid and / or steam flow. The steam cooking inner container 14 is communicatively connected to the range hood system 2 in an openable and closable manner so that the excess steam discharged from the steam cooking system 1 is used for cleaning the range hood system 2. The first water pump 12 and the first evaporator 13 are respectively communicatively connected to the controller. The cleaning control method for the integrated range hood includes: setting an initial pump water volume Q1 of the first water pump 12, a preheating temperature T of the steam cooking inner container 14 蒸 and a steaming duration t 蒸 in the controller; the controller starts the first water pump 12 to pump water to the initial pump water volume Q1 and starts the first evaporator 13 to heat the steam cooking inner container 14 to the preheating temperature T 蒸 ; the controller starts the range hood system 2 and starts timing t, and the excess steam in the steam cooking inner container 14 enters the range hood system 2 for cleaning; when t = t 蒸 , the steaming ends, and the controller turns off the range hood system 2 and the first evaporator 13.

[0030] As Figures 1 to 3 shown, the integrated range hood includes a steaming and baking system 1 and a fume exhaust system 2. The fume exhaust system 2 includes a blower cabinet 21 and a blower 22 disposed inside the blower cabinet 21. The blower cabinet 21 is disposed on one side of the steaming and baking system 1 close to the wall. A water tank 11, a first water pump 12, and a first evaporator 13 are disposed on the top of the steaming and baking system 1 and are connected in sequence. The first evaporator 13 is connected to a steaming and baking inner container 14. The steaming and baking inner container 14 is connected to the blower cabinet 21 in an openable and closable manner. The initial pump water volume Q1 of the first water pump 12 and the preheating temperature T 蒸 of the first evaporator 13 are set in the controller, and the steaming duration t 蒸 , that is, the working duration of the steaming and baking system 1, is set according to the food to be cooked. Preferably, the first water pump 12 is a water pump with a flow rate of 18 ml / s. The initial pump water volume Q1 can be set according to the capacity of the first evaporator 13. For example, when the capacity of the first evaporator 13 is 400 ml to 500 ml, the initial working duration of the first water pump 12 is set to 20 s, and then the initial pump water volume Q1 of the first water pump 12 can be set to 360 ml. The value of the preheating temperature T 蒸 is any value between 60°C and 120°C, preferably 95°C. During normal cooking, the water tank 11 is filled with water, and the first water pump 12 pumps water with a volume of Q1 into the first evaporator 13. Specifically, the first evaporator 13 includes a heating plate and a first heater connected to the bottom of the heating plate. The heating plate is used to hold the water pumped by the first water pump 12. The water is evaporated into steam by the heating of the first heater to heat the food in the steaming and baking inner container 14 to the preheating temperature T 蒸 . After that, the controller starts the fume exhaust system 2 and starts timing t. When t < t 蒸 , the excess steam in the steaming and baking inner container 14 enters the fume exhaust system 2 for cleaning. Preferably, a one-way valve communicatively connected to the controller is provided at the connection between the steaming and baking inner container 14 and the fume exhaust system 2, and pressure sensors are respectively provided in the steaming and baking inner container 14 and the fume exhaust system 2. By detecting and comparing the pressure in the steaming and baking inner container 14 and the pressure in the fume exhaust system 2, when the pressure in the steaming and baking inner container 14 is greater than the pressure in the fume exhaust system 2 by a certain amount, the one-way valve opens, and the excess steam is discharged to the fume exhaust system 2 to clean the inner wall of the blower cabinet 21 and the blower 22. The working gears of the blower 22 can also be set to high speed, medium speed, and low speed. During the middle section of the cooking duration, it operates in the low speed gear, which can make the steam evenly spray on each position of the fume exhaust system 2, and melt the mild oil scale and oil stains under the action of the high-temperature steam. When the cooking is about to end, it operates in the high speed gear to completely shake off the water droplets with residual oil scale and oil stains formed on the blower 22 as much as possible. For example, when the cooking duration t 蒸 is set to 30 minutes, the blower 22 can be set to operate in the low speed gear for the first 25 minutes, and the high speed gear for the last 5 minutes.

[0031] Furthermore, a water outlet is provided at the bottom of the air cabinet 21 of the range hood system 2. The integrated stove further includes an oil drip tray 3, which is arranged corresponding to the water outlet. When the fan 22 rotates, the water with oil stains can be thrown onto the inner side wall of the air cabinet 21 due to centrifugal force, and the water flows along the inner side wall of the air cabinet 21 to the water outlet, and then flows into the oil drip tray 3.

[0032] In a preferred embodiment of the present invention, the steam cooking and baking system 1 further includes a heating pipe 15 and a first temperature sensor 16 arranged in the steam cooking and baking inner container 14. The first temperature sensor 16 is used to detect the first real-time temperature T of the steam cooking and baking inner container 14. 实1 , and the heating pipe 15 is used to assist in heating the steam in the steam cooking and baking inner container 14. The controller starts the range hood system 2 and starts timing t. The excess steam in the steam cooking and baking inner container 14 enters the range hood system 2 for cleaning, including: setting the maximum cooking temperature T in the controller. 高 and the minimum cooking temperature T. 低 , where T. 低 <T. 高 ; the first temperature sensor 16 obtains the first real-time temperature T. 实1 and transmits it to the controller. The controller compares T. 实 with T. 高 and T. 低 ; when T. 实1 ≥T. 高 , the controller turns off the heating pipe 15 and connects the steam cooking and baking inner container 14 and the range hood system 2, so that the excess steam in the steam cooking and baking inner container 14 enters the range hood system 2 for cleaning; when T. 低 ≤T. 实1 ≤T. 高 , the controller turns on the heating pipe 15 and connects the steam cooking and baking inner container 14 and the range hood system 2, so that the excess steam in the inner container enters the range hood system 2 for cleaning; when T. 实1 ≤T. 低 , the controller turns on the heating pipe 15 and disconnects the steam cooking and baking inner container 14 and the range hood system 2, so that the steam generated by the first evaporator 13 quickly reaches the cooking temperature. The maximum cooking temperature T. 高 is 125° to 135°, and the minimum cooking temperature T. 低 is 80° to 90°.

[0033] As Figures 1 to 3 shown, the heating pipe 15 is arranged in the steam cooking and baking inner container 14, and can be arranged on the top wall or the bottom wall or the side wall of the steam cooking and baking inner container 14. The heating pipe 15 is communicatively connected to the controller. The first temperature sensor 16 is also arranged in the steam cooking and baking inner container 14 and is used to detect the temperature inside the steam cooking and baking inner container 14. During the t. 蒸 time period, the first temperature sensor 16 continuously detects the steam temperature T in the cooking inner container. 实1, any number between 125° and 135° is set as the maximum cooking temperature T in the controller 高 , preferably 130 °C, set T 高 to be the same value as the steaming temperature, and any number between 80° and 90° is set as the minimum cooking temperature T 低 , preferably 90 °C, when T 实1 ≥ T 高 , the controller turns off the heating pipe 15 to stop the auxiliary heating of the steam in the cooking inner container, and at the same time discharges the excess steam to the range hood system 2. When T 低 ≤ T 实1 ≤ T 高 , the controller turns on the heating pipe 15 to assist in heating the steam in the steam baking inner container 14, accelerating the steam in the steam baking inner container 14 to quickly reach T 高 and at the same time discharges the excess steam into the range hood system 2 for cleaning. When T 实1 ≤ T 低 , the heating pipe 15 continuously heats and disconnects the steam baking inner container 14 and the range hood system 2, so that the steam baking inner container 14 is in a relatively closed state, facilitating the heating pipe 15 to concentrate on heating the steam entering the steam baking inner container 14 to reach the cooking temperature. However, when a large amount of steam enters the steam baking inner container 14, in order to balance the pressure in the steam baking inner container 14 and the pressure in the range hood system 2, the controller will still connect the steam baking inner container 14 and the range hood system 2.

[0034] In a preferred embodiment of the present invention, a second temperature sensor for communicating with the controller is provided in the first evaporator 13, and the second temperature sensor is used to detect the second real-time temperature T of the first evaporator 13 实2 , the integrated stove cleaning control method further includes: setting the first dry-burning temperature T of the first evaporator 13 in the controller 干烧1 and the pumping duration t of the first water pump 12 泵1 ; the second temperature sensor obtains the second real-time temperature T 实2 and transmits it to the controller, and the controller compares T 实2 with T 干烧1 ; when T 实2 ≥ T 干烧1 , the controller turns on the first water pump 12 for pumping water for a duration of t 泵1 .

[0035] As Figure 2 and Figure 3 shown, the first dry-burning temperature T is set in the controller 干烧1 , preferably set T 干烧1 to be 125 °C. When the second temperature sensor detects that the temperature T in the first evaporator 13 实2 is equal to or higher than the first dry-burning temperature T 干烧1When the controller determines that the first evaporator 13 is in a dry-burning state or is about to be in a dry-burning state, the first water pump 12 is turned on for a duration of t 泵1 to pump water, so as to transport the water in the water tank 11 into the first evaporator 13 to prevent dry burning in the first evaporator 13. Specifically, when the first water pump 12 is a water pump with a flow rate of 18 ml / s, t 泵1 is set to 6 s in the controller.

[0036] In a preferred embodiment of the present invention, a first operating frequency f1 of the first evaporator 13 is set in the controller. After the first evaporator 13 heats the steaming and baking inner cavity 14 to the preheating temperature T 蒸 the first evaporator 13 operates at the first operating frequency f1 to control the amount of steam entering the steaming and baking inner cavity 14.

[0037] As Figure 2 and Figure 3 shown, in order to control the amount of steam entering the steaming and baking inner cavity 14 and the water consumption, and at the same time extend the service life of the first evaporator 13, the first operating frequency f1 of the first evaporator 13 is set according to the power of the first evaporator 13. Specifically, when the power of the first evaporator 13 is between 800 W and 1200 W, the first operating frequency f1 is set to operate for 50 s and stop for 10 s. After the first evaporator 13 heats the temperature in the steaming and baking inner cavity 14 to the preheating temperature T 蒸 the first evaporator 13 then performs intermittent heating at the first operating frequency f1.

[0038] In a preferred embodiment of the present invention, the steaming and baking system 1 further includes a second water pump 17 and a second evaporator 18 that are sequentially connected in communication along the liquid and / or steam flow direction. The second water pump 17 is connected to the water tank 11, the second evaporator 18 is connected to the steaming and baking inner cavity 14, and the second evaporator 18 and the second water pump 17 are respectively in communication connection with the controller. The integrated stove cleaning control method further includes: setting an initial pump water volume Q2 of the second water pump 17 in the controller; the controller starts the second water pump 17 to pump water to the initial pump water volume Q2, and starts the second evaporator 18, so that the first evaporator 13 and the second evaporator 18 generate steam synchronously to cook the food in the steaming and baking inner cavity 14 and clean the range hood system 2.

[0039] As Figure 2 and Figure 3As shown, the water inlet end of the second water pump 17 is communicated with the water tank 11. The second evaporator 18 includes a first output end and a second output end, wherein the first output end is communicated with the range hood system 2, and the second output end is communicated with the steaming and baking inner container 14. According to the flow rate of the second water pump 17 being 18 ml / s, the working duration of the second water pump 17 is set to 20 s in the controller, so that the initial pump water volume Q2 of the second water pump 17 can be set to 360 ml. It can also be directly setting the initial pump water volume Q2 of the second water pump 17 in the controller. The preheating temperature T 蒸2 of the second evaporator 18 takes any value from 60°C to 120°C, preferably 95°C. When it is necessary to accelerate the steaming cooking, the controller starts the first evaporator 13 and the second evaporator 18 to work simultaneously. The steam generated by the first evaporator 13 completely enters the steaming and baking inner container 14, and part of the steam generated by the second evaporator 18 enters the steaming and baking inner container 14, accelerating the steaming of the food in the steaming and baking inner container 14. The excess steam enters the range hood system 2 for cleaning, and another part of the steam generated by the second evaporator 18 directly enters the range hood system 2 for cleaning, ensuring the cleaning of the mild oil stain on the range hood during the process of accelerating the steaming cooking.

[0040] In a preferred embodiment of the present invention, the steaming and baking system 1 further includes a first solenoid valve 191 and a second solenoid valve 192. The first solenoid valve 191 is used for the openable and closable communication between the second evaporator 18 and the steaming and baking inner container 14, and the second solenoid valve 192 is used for the openable and closable communication between the second evaporator 18 and the range hood system 2. When the first solenoid valve 191 connects the second evaporator 18 and the steaming and baking inner container 14 and the second solenoid valve 192 disconnects the second evaporator 18 and the range hood system 2, cooking is carried out by synchronously generating steam through the first evaporator 13 and the second evaporator 18, and the excess steam enters the range hood system 2 from the steaming and baking inner container 14; when the first solenoid valve 191 disconnects the second evaporator 18 and the steaming and baking inner container 14 and the second solenoid valve 192 connects the second evaporator 18 and the range hood system 2, the steam generated by the first steam generator and the second evaporator 18 respectively enters the range hood system 2.

[0041] As Figure 2 and Figure 3As shown, the first output end of the second evaporator 18 and the range hood system 2 are connected through a first air pipe, and a first electromagnetic valve 191 is arranged on the first air pipe to realize the on-off of the second evaporator 18 and the range hood system 2. The second output end of the second evaporator 18 and the steaming and baking inner container 14 are connected through a second air pipe, and a second electromagnetic valve 192 is arranged on the second air pipe to realize the on-off of the second evaporator 18 and the range hood system 2. When performing rapid cooking, the first electromagnetic valve 191 is opened and the second electromagnetic valve 192 is closed, so that the steam generated by the first evaporator 13 and the second evaporator 18 all enters the steaming and baking inner container 14 completely. When the excess steam completely enters the range hood system 2 from the steaming and baking inner container 14 to accelerate and thoroughly clean the range hood system 2, the first electromagnetic valve 191 is closed and the second electromagnetic valve 192 is opened. The steam generated by the first evaporator 13 enters the range hood system 2 from the steaming and baking inner container 14, and the steam generated by the second evaporator 18 directly enters the range hood system 2. The range hood system 2 is cleaned by all the steam generated by the first evaporator 13 and the second evaporator 18, and the accumulated oil dirt and oil on the inner side wall of the air cabinet 21 and the fan 22 can be removed.

[0042] In a preferred embodiment of the present invention, the controller sets the continuous working duration t2 of the second evaporator 18 and the delay working duration t of the range hood 烟机 , when the first electromagnetic valve 191 disconnects the second evaporator 18 and the steaming and baking inner container 14, and the second electromagnetic valve 192 connects the second evaporator 18 and the range hood system 2, the steam generated by the first steam generator and the second evaporator 18 enters the range hood system 2 respectively, including: the first electromagnetic valve 191 disconnects the second evaporator 18 and the steaming and baking inner container 14, the second electromagnetic valve 192 connects the second evaporator 18 and the range hood system 2, and the first water pump 12 and the first evaporator 13 are in the closed state; the range hood system 2 is started, and the second evaporator 18 works continuously for a duration t2; the controller closes the second evaporator 18 and starts timing t 烟机 '; when t 烟机 ' = t 烟机 , the controller closes the range hood system 2.

[0043] As Figure 2 and Figure 3 shown, the first electromagnetic valve 191 disconnects the second evaporator 18 and the steaming and baking inner container 14 to prevent the steam generated by the second evaporator 18 from entering the steaming and baking inner container 14. The second electromagnetic valve 192 connects the second evaporator 18 and the range hood system 2, so that the steam generated by the second evaporator 18 can completely enter the range hood system 2. At the same time, the first evaporator 13 and the first water pump 12 are closed to stop the cooking work of the steaming and baking system 1. A separate cleaning process is carried out on the range hood system 2. The second water pump 17, the second evaporator 18 and the range hood system 2 are started, and the second evaporator 18 heats the water to the preheating temperature T 蒸2After that, the blower 22 of the range hood system 2 operates at a low speed gear. Specifically, the blower 22 rotates slowly at a working frequency of running for 5 s and stopping for 20 s in the low speed gear. During the time t2, the second evaporator 18 continuously heats up, so as to generate enough steam to clean the blower 22 and the air cabinet 21. When the water pumping flow rate of the second water pump 17 increases, steam and warm water can be generated simultaneously to clean the range hood. After the time t2, the controller turns off the second evaporator 18 and starts timing t 烟机 '. When t 烟机 ' = t 烟机 , the controller determines that the range hood system 2 has completely drained the water droplets with oil stains, and thus turns off the range hood system 2.

[0044] In a preferred embodiment of the present invention, a third temperature sensor communicatively connected to the controller is provided in the second evaporator 18. The third temperature sensor is used to detect the third real-time temperature T 实3 of the second evaporator 18. The second dry-burning temperature T 干烧2 of the second evaporator 18 and the water pumping duration t 泵2 of the second water pump 17 are set in the controller. During the time t2, the third temperature sensor obtains the third real-time temperature T 实3 and transmits it to the controller. The controller compares T 实3 with T 干烧2 . When T 实3 ≥T 干烧2 , the controller turns on the second water pump 17 for water pumping for a duration of t 泵2 .

[0045] As Figure 2 and Figure 3 shown, the second dry-burning temperature T 干烧2 is set in the controller. Preferably, T 干烧2 is set to 125 °C. When the third temperature sensor detects that the temperature T 实3 in the second evaporator 18 is equal to or higher than the second dry-burning temperature T 干烧2 , the controller determines that the second evaporator 18 is in a dry-burning state or about to be in a dry-burning state, and thus turns on the second water pump 17 for water pumping for a duration of t 泵2 to deliver the water in the water tank 11 into the second evaporator 18 to prevent dry-burning in the second evaporator 18. Specifically, when the second water pump 17 is a water pump with a flow rate of 18 ml / s, then t 泵2 is set to 6 s in the controller.

[0046] In a preferred embodiment of the present invention, a second working frequency f2 of the second water pump 17 is set in the controller. After starting the range hood system 2, the second water pump 17 pumps water at the second working frequency f2 to generate steam and warm water to enter the range hood system 2 for cleaning.

[0047] As shown in Figure 2 and Figure 3 shown, since it is a normal cleaning of the range hood system 2 to remove a small amount of oil stains and the duration is short, even if the second evaporator 18 remains in an operating state all the time, it will not be damaged. Specifically, the power of the second evaporator 18 is 1000w to 1400w, the flow rate of the second water pump 17 is 18ml / s, and the second working frequency f2 of the second water pump 17 is set in the controller to turn on for 5s and stop for 30s. Within the time t2, warm water, hot water and steam can overflow from the second evaporator 18 to clean the range hood system 2.

[0048] In a preferred embodiment of the present invention, a fourth temperature sensor communicating with the controller is provided in the first evaporator 13, and the fourth temperature sensor is used to detect the fourth real-time temperature T of the second evaporator 18 实4 , and the integrated range hood cleaning control method further includes: setting the third dry-burning temperature T of the second evaporator 18 in the controller 干烧3 , as well as the continuous working duration t3 of the first evaporator 13 and the second evaporator 18; the first solenoid valve 191 disconnects the second evaporator 18 and the steam cooking and baking inner cavity 14, the second solenoid valve 192 connects the second evaporator 18 and the range hood system 2, and the first water pump 12 and the first evaporator 13 are in an open state; the range hood system 2 is started, and the first evaporator 13 and the second evaporator 18 work continuously for the duration t3; the controller turns off the second evaporator 18 and obtains the fourth real-time temperature T of the first evaporator 13 实4 , and compares T 实4 with T 干烧3 ; when T 实4 ≥T 干烧3 , the controller turns off the range hood system 2.

[0049] As shown in Figure 2 and Figure 3 shown, the third dry-burning temperature T of the second evaporator 18 is set in the controller 干烧3 , and the third dry-burning temperature T 干烧3 can be equivalent to the second dry-burning temperature T 干烧2 , that is, set to 125°C. The fourth temperature sensor and the third temperature sensor can be the same one, and are also used to detect the real-time temperature inside the second evaporator 18. The difference is the time of their use. When a temperature sensor is provided inside the second evaporator 18, this temperature sensor can detect the third real-time temperature T of the second evaporator 18 during the t2 duration of normal cleaning using the second evaporator 18 alone 实3 , and can also detect the fourth real-time temperature T of the second evaporator 18 after the t3 duration of accelerated cleaning using the first evaporator 13 and the second evaporator 18 simultaneously 实4 . When T 实4 ≥T 干烧3When this occurs, the controller determines that the second evaporator 18 has already or is about to be in a dry-burning state, and shuts down the range hood system 2, which can completely drain the water vapor in the second evaporator 18, avoiding the growth of bacteria due to the long-term moist state of the second evaporator 18 and the water circuit where the second evaporator 18 is located.

[0050] In the integrated range hood cleaning control method of the present invention, the initial pump water volume Q1 of the first water pump 12, the preheating temperature T of the first evaporator 13, and 蒸1 the steaming duration t are set in the controller. 蒸 After starting the first evaporator 13 to heat to the preheating temperature T, 蒸1 the timing t is started. When t < t, 蒸 through the openable and closable connection between the steaming and baking inner cavity 14 and the range hood system 2, the excess steam is discharged to be used for the daily cleaning of the range hood system 2 by maintaining the pressure balance between the steaming and baking inner cavity 14 and the range hood system 2. It is possible to clean the range hood system 2 by using the excess steam discharged from the steaming and baking inner cavity 14 while the user is cooking with the steaming and baking system 1, reducing the difficulty of daily cleaning and maintenance of the integrated range hood; the addition of the second water pump 17 and the second evaporator 18 enables the user to start the first evaporator 13 and the second evaporator 18 simultaneously to treat stubborn oil stains whether or not cooking; a first electromagnetic valve 191 is provided for the openable and closable connection between the second evaporator 18 and the steaming and baking inner cavity 14, and a second electromagnetic valve 192 is provided for the openable and closable connection between the second evaporator 18 and the range hood system 2. When using both the first evaporator 13 and the second evaporator 18 for treating the oil stains in the range hood system 2, by opening and closing the first electromagnetic valve 191 and the second electromagnetic valve 192, the working frequency f2 of the second water pump 17 is controlled, so that the steam generated by the first evaporator 13 can enter the range hood system 2, and the mixture of steam and warm water generated by the second evaporator 18 can be used to flush the range hood system 2, further removing stubborn oil scale and oil stains in the range hood system 2.
