Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and particularly relates to a control method for an integrated range hood and an integrated range hood. Background Art

[0002] Integration is the development direction of future cooking equipment. However, existing integrated range hoods generally integrate cooktops with steam ovens, or ovens, or dishwashers, or disinfection cabinets, etc. There are the following problems:

[0003] 1) The general steam discharge and heat dissipation method of existing integrated range hoods or steam baking cooking devices is to blow the generated remaining steam outwards through the air duct from the inside to the outside, resulting in a relatively high humidity and temperature in the kitchen space. This steam will also blow towards the user, causing discomfort to the user.

[0004] 2) Most of the cooking fumes generated by current steam baking cooking devices on the market are directly discharged into the kitchen space without better recovery. Summary of the Invention

[0005] The purpose of the present invention is to provide a control method for an integrated range hood. By establishing the corresponding relationship between the cooking range of the cooktop and the suction range of the range hood, and the corresponding relationship between the cooking range of the steam baking cooking device and the suction range of the range hood. In particular, when the cooktop and the steam baking cooking device are started simultaneously, the integrated range hood can intelligently adjust the suction range of the range hood, enabling the range hood to have a better exhaust and purification effect on cooking fumes and polluted air per unit time, reducing power consumption, improving the kitchen use environment, and enhancing the user experience.

[0006] The purpose of the present invention is to provide an integrated range hood. Through the exhaust component, it can prevent the gas discharged from the steam baking cooking device from directly discharging into the kitchen. Part of the gas discharged from the steam baking cooking device is sucked away by the range hood, and part of the gas discharged from the steam baking cooking device forms condensed water after condensation in the exhaust component. The condensed water flows into the evaporator, preventing the gas generated by the steam baking cooking device from directly discharging into the kitchen and reusing the formed condensed water, improving the utilization rate of steam.

[0007] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0008] According to one aspect of the present invention, a control method for an integrated range hood is provided.

[0062] As Figure 1 , 6 -7 shows, Figure 1 shows the control logic diagram of the control method for the integrated cooking stove provided by the present invention. Figure 6 shows the workflow diagram of the integrated cooking stove provided by the present invention.Figure 7 The figure shows a schematic diagram of the integrated stove provided by the present invention.

[0063] A control method for an integrated stove according to an embodiment of the present invention. The integrated stove includes a cooking stove 1, a steaming and baking cooking device 2, and a range hood 3. Among them, the cooking stove 1 is arranged above the steaming and baking cooking device 2, and the range hood 3 is arranged above the cooking stove 1. The control method includes:

[0064] Detect whether the cooking stove 1 and the steaming and baking cooking device 2 are started;

[0065] If only the cooking stove 1 is started, the range hood 3 is started, and the corresponding relationship between the gear of the cooking stove 1 and the gear of the range hood 3 is selected. The gear of the cooking stove 1 is detected in real time, and the gear of the range hood 3 is adjusted according to the detected gear of the cooking stove 1. After the cooking stove 1 is turned off, the range hood 3 continues to work for a set time and then is turned off;

[0066] If only the steaming and baking cooking device 2 is started, the range hood 3 is started, and the corresponding relationship between the gear of the steaming and baking cooking device 2 and the gear of the range hood 3 is selected. The gear of the steaming and baking cooking device 2 is detected in real time, and the gear of the range hood 3 is adjusted according to the detected gear of the steaming and baking cooking device 2. After the steaming and baking cooking device 2 is turned off, the range hood 3 continues to work for a set time and then is turned off;

[0067] If the cooking stove 1 and the steaming and baking cooking device 2 are started simultaneously, the range hood 3 is started, and the corresponding relationship between the gears of the cooking stove 1 and the steaming and baking cooking device 2 and the gear of the range hood 3 is selected. The gears of the cooking stove 1 and the steaming and baking cooking device 2 are detected in real time, and the gear of the range hood 3 is adjusted according to the detected gears of the cooking stove 1 and the steaming and baking cooking device 2. After the cooking stove 1 and the steaming and baking cooking device 2 are both turned off, the range hood 3 continues to work for a set time and then is turned off.

[0068] Among them, because when the gear of the cooking stove 1 or the gear of the steaming and baking cooking device 2 is low, when the range hood 3 is turned on at a large gear, the oil fume extraction effect is not good and it consumes a lot of electricity. Therefore, it is necessary to establish the corresponding relationship between the gear of the cooking stove 1 and the gear of the range hood 3, and the corresponding relationship between the gear of the steaming and baking cooking device 2 and the gear of the range hood 3. Especially when the cooking stove 1 and the steaming and baking cooking device 2 are started simultaneously, the corresponding relationship between the gears of the cooking stove 1 and the steaming and baking cooking device 2 and the gear of the range hood 3 is selected. In this embodiment, the firepower of the cooking stove 1 becomes larger as the gear increases, the steam emission amount of the steaming and baking cooking device 2 becomes larger as the gear increases, and the suction of the range hood 3 becomes larger as the gear increases. On this basis, the corresponding relationship among the cooking stove 1, the steaming and baking cooking device 2, and the range hood 3 is established.

[0069] When only the cooking appliance 1 is started, the firepower of the cooking appliance 1 increases as the gear level increases, and the gear level of the range hood 3 should also increase accordingly. If only the steam cooking and roasting device 2 is started, when the steam emission amount of the steam cooking and roasting device 2 increases, the corresponding gear level of the range hood 3 should also be adjusted accordingly with the change of the steam amount. When the cooking appliance 1 and the steam cooking and roasting device 2 are started simultaneously, for the corresponding relationship between the gear levels of the cooking appliance 1 and the steam cooking and roasting device 2 and the gear level of the range hood 3, adjusting the gear level of the range hood 3 can make the range hood 3 have a better effect of exhausting and purifying oil fumes and dirty air per unit time, can also reduce the power consumption, improve the kitchen use environment and enhance the user experience.

[0070] In addition, after both the cooking appliance 1 and the steam cooking and roasting device 2 are turned off, the range hood 3 needs to continue working for a set time, such as 3 to 5 minutes, so as to fully suck away the kitchen fumes.

[0071] In a preferred embodiment of the present invention, during the start-up and working process of the steam cooking and roasting device 2, the working mode of the steam cooking and roasting device 2 is identified. The working mode of the steam cooking and roasting device 2 includes a steam mode and a non-steam mode.

[0072] If the working mode of the steam cooking and roasting device 2 is the steam mode, it is necessary to detect the steam gear level in real time and match the corresponding gear level of the range hood 3 according to the steam gear level. If the steam cooking and roasting device 2 is in the non-steam mode, the range hood 3 is started and is in the lowest gear.

[0073] As Figure 7 shown, the steam cooking and roasting device 2 includes a steam mode and a non-steam mode. Among them, the steam mode includes a steaming function and a steam cooking and roasting function, that is, it is necessary to process food using steam. At this time, it is necessary to detect the steam gear level set by the user and match the corresponding gear level of the range hood 3 according to the steam gear level. For example, if there are small steam gears, medium steam gears, and high steam gears for the steam gear level, and there are 3 gears for the suction force of the range hood 3, the corresponding relationship between the steam gear level and the gear level of the range hood 3 is that the small steam gear corresponds to the 1st gear of the range hood 3, the medium steam gear corresponds to the 2nd gear of the range hood 3, and the high steam corresponds to the 3rd gear of the range hood 3. The non-steam mode means that steam is not required during the food processing process. At this time, the steam cooking and roasting device 2 is equivalent to an oven, and the fumes generated during this process are relatively small. The range hood 3 can effectively extract the fumes and purify the air in the kitchen at the lowest gear. Through the above settings, the range hood 3 can not only effectively suck away the steam generated by the steam cooking and roasting device 2, avoid the steam from entering the kitchen and causing the humidity and temperature in the kitchen space to be too high and the user to feel uncomfortable, but also avoid the gear level of the range hood 3 being too large and causing unnecessary energy waste.

[0074] In a preferred embodiment of the present invention, the steam baking cooking device 2 includes an inner container and a water tank. The water tank is communicated with the inner container. If the steam baking cooking device 2 is turned on in the steam mode, it is necessary to detect in real time whether the water tank is short of water. If it is short of water, a water addition alarm is issued.

[0075] After the water addition alarm is issued, after a set water addition time, if water addition is detected, the range hood 3 is adjusted to the lowest gear, and at the same time, water is added to the set position, and the steam baking cooking device 2 continues to work.

[0076] After the water addition alarm is issued, after the set water addition time, if no water addition is found, the steam baking cooking device 2 is turned off.

[0077] Among them, when the steam baking cooking device 2 is started and turned on in the steam mode, it is necessary to detect in real time whether the water tank is short of water. If it is short of water, a water addition alarm is issued. If no water is added after the set water addition time, the steam baking cooking device 2 needs to be turned off to protect the steam baking cooking device 2. If water is added within the set water addition time, at this time, the generation of steam in the steam baking cooking device 2 will decrease, and the range hood 3 should be adjusted to the first gear, that is, the lowest gear, until the water is added to the set position, and the steam baking cooking device 2 continues to work until the steam baking cooking device 2 finishes working.

[0078] In a preferred embodiment of the present invention, during the simultaneous use of the cooker 1 and the steam baking cooking device 2, if one of the cooker 1 and the steam baking cooking device 2 is turned off, the process continues according to the other one.

[0079] As Figure 7 shown, when the cooker 1 and the steam baking cooking device 2 are used simultaneously, if the cooker 1 is turned off, according to the process of only starting the steam baking cooking device 2, the corresponding relationship between the gear of the steam baking cooking device 2 and the gear of the range hood 3 is selected, the working mode of the steam baking cooking device 2 is detected, the steam gear and the water tank condition in the steam mode are detected, and the gear of the range hood 3 is adjusted in time to avoid the problem of poor oil fume emission effect caused by the gear of the range hood 3 being too large or too small.

[0080] Similarly, when the cooker 1 and the steam baking cooking device 2 are used simultaneously, if the steam baking cooking device 2 is turned off, according to the process of only starting the cooker 1, the corresponding relationship between the gear of the cooker 1 and the gear of the range hood 3 is selected, and the gear of the range hood 3 is adjusted in time according to the gear of the cooker 1.

[0081] This embodiment can adjust the unit of the range hood 3 in time according to the operating conditions of the cooker 1 and the steam baking cooking device 2, so that the range hood 3 can not only timely extract the steam generated by the cooker 1 and the steam baking cooking device 2, avoid the oil fume and steam from entering the kitchen and causing the humidity and temperature of the kitchen space to be too high and the user to be uncomfortable, but also avoid the range hood 3 having too large a gear and causing unnecessary energy waste.

[0082] In a preferred embodiment of the present invention, the cooking appliance 1 includes a left burner and a right burner. The heating power of the left burner is a, the heating power intensity coefficient of the left burner is V1, the number of power levels of the left burner is N, the heating power of the right burner is b, the heating power intensity coefficient of the right burner is V2, the number of power levels of the right burner is M, and the heating power intensity of the cooking appliance 1 is E. Then E （i,j） =a i ×V1 + b j ×V2,

[0083] In the formula, i is the current power level of the left burner, i = 0, 1, 2, 3,..., N; j is the current power level of the right burner, j = 0, 1, 2, 3,..., M; a i is the heating power of the left burner at the i-th level; b j is the heating power of the right burner at the j-th level; E （i,j） represents the heating power intensity of the cooking appliance 1 when the power level of the left burner is at the i-th level and the power level of the right burner is at the j-th level; V1 < V2;

[0084] The heating power intensity of the steam cooking and roasting device 2 is W, the steam intensity of the steam cooking and roasting device 2 is Q, and the number of power levels of the steam cooking and roasting device 2 is P. Among them, W k =Q k ×f. In the formula, k is the current power level of the steam cooking and roasting device 2, k = 0, 1, 2, 3,..., P; f is the conversion coefficient for converting the steam intensity of the steam cooking and roasting device 2 into the heating power intensity;

[0085] When the cooking appliance 1 and the steam cooking and roasting device 2 are started simultaneously, the heating power intensity is T. Among them, T = E + W.

[0086] As Figure 1 shown, in this embodiment, the cooking appliance 1 includes a left burner and a right burner. The heating power intensity value E of the cooking appliance 1 is calculated based on the heating power and heating power intensity coefficients of the two burners. In this way, the heating power intensity value E of the cooking appliance 1 can be calculated under different power levels of the left burner and the right burner. According to the number of power levels of the range hood 3, the heating power intensity value E of the cooking appliance 1 is grouped so that the heating power intensity value E of the cooking appliance 1 corresponds to the power level of the range hood 3, improving the purification effect of the range hood 3.

[0087] Similarly, when only the steam cooking and roasting device 2 is started, it can correspond to the steam intensity Q of the steam cooking and roasting device 2 with the power level of the range hood 3, or it can calculate the heating power intensity value W of the steam cooking and roasting device 2 at different power levels according to the steam intensity Q and the conversion coefficient f for converting the steam intensity into the heating power intensity, and establish a relationship between the heating power intensity value of the steam cooking and roasting device 2 and the power level of the range hood 3 so that the range hood 3 can extract the gas generated by the steam cooking and roasting device 2, improving the kitchen environment.

[0088] To solve the problem of the corresponding relationship between the gears of the cooking appliance 1 and the steam cooking and baking appliance 2 and the gear of the range hood 3 when the cooking appliance 1 and the steam cooking and baking appliance 2 are started simultaneously, in this embodiment, by adding the fire intensity value E of the cooking appliance 1 and the fire intensity value W of the steam cooking and baking appliance 2, the fire intensity T when the cooking appliance 1 and the steam cooking and baking appliance 2 are started simultaneously can be obtained. In this way, by grouping the fire intensity T and corresponding it to the corresponding relationship of the gears of the range hood 3, the gear of the range hood 3 can be matched with the flue gas emission when the cooking appliance 1 and the steam cooking and baking appliance 2 are started simultaneously, and the purification effect of the range hood 3 can be improved.

[0089] It should be noted that when i takes the value of 0, it means that the left burner is not started; when j takes the value of 0, it means that the burner is not started; when k takes the value of 0, it means that the steam cooking and baking appliance 2 is not started.

[0090] In a preferred embodiment of the present invention, the gear of the range hood 3 is L, where L is less than or equal to N, M, and P. When only the cooking appliance 1 is started, the fire intensity values corresponding to the gears of the range hood 3 from low to high are [E （1,0） , E （N,M） / L], (E （N,M） / L, E （N,M） / (L - 1)], (E （N,M） / (L - 1), E （N,M） / (L - 2)],..., (E （N,M） / 3, E （N,M） / 2], (E （N,M） / 2, E （N,M） .

[0091] As Figures 6-7 shown, when only the cooking appliance 1 is started, first calculate the minimum value E （1,0） and the maximum value E （N,M） of the fire intensity E of the cooking appliance 1. Secondly, group according to the number of gears of the range hood 3. Taking the cooking appliance 1 and the range hood 3 both having 4 gears as an example for illustration, when only the left burner of the cooking appliance 1 is turned on and is in the 1st gear, E （1,0） =a1×V1; when both the left burner and the right burner are in the 1st gear, E （1,1） =a1×V1 + b1×V2; when both the left burner and the right burner are in the 2nd gear, E （2,2） =a2×V1 + b2×V2; when both the left burner and the right burner are in the 3rd gear, E （3,3） =a3×V1 + b3×V2; when both the left burner and the right burner are in the 4th gear, E （4,4） =a4×V1 + b4×V2; since the fire power of both the left burner and the right burner increases with the increase of the gear, that is, a1 < a2 < a3 < a4, b1 < b2 < b3 < b4, it can be seen that the minimum fire power value of the cooking appliance 1 is E （1,0） , and the maximum fire power value is E（4,4） , the relationship between the firepower intensity of the cooking stove 1 and the gear of the range hood 3 is as follows: when the firepower intensity value of the cooking stove 1 is within [E （1,0） ~E （4,4） / 4], the suction of the range hood 3 is at gear 1; when the firepower intensity value of the cooking stove 1 is within (E （4,4） / 4, E （4,4） / 3], the suction of the range hood 3 is at gear 2; when the firepower intensity value of the cooking stove 1 is within (E （4,4） / 3, E （4,4） / 2], the suction of the range hood 3 is at gear 3; when the firepower intensity value of the cooking stove 1 is within (E （4,4） / 2, E （4,4） , the suction of the range hood 3 is at gear 4. In this way, only the gears of the left burner and the right burner on the cooking stove 1 need to be detected, and then according to the firepower of the corresponding gear, the firepower intensity value of the cooking stove 1 can be calculated. Through the above relationship, the system can automatically match the corresponding gear of the range hood 3, improving the intelligence of the equipment and the effect of oil fume extraction.

[0092] In a preferred embodiment of the present invention, the gear of the range hood 3 is L, where L is less than or equal to N, M, and P. When only the steam cooking and baking device 2 is started, the steam intensities corresponding to the gears of the range hood 3 from low to high are [Q1, Q p / L], (Q p / L, Q p / (L - 1)], (Q p / (L - 1), Q p / (L - 2)],..., (Q p / 3, Q p / 2], (Q p / 2, Q p .

[0093] Such as Figure 7, when only the steam cooking device 2 is started and recognized as the steam mode, the system obtains the steam intensities Q of different gears of the steam cooking device 2, and groups the steam intensities according to the number of gears of the range hood 3. Of course, the steam intensity can also be converted into the corresponding fire intensity of the steam cooking device 2, and then the corresponding relationship between the gears of the steam cooking device 2 and the gears of the range hood 3 is constructed. Taking the steam cooking device 2 with 4 gears and the range hood 3 with 4 gears as an example, the steam intensities of the steam cooking device 2 from low to high are Q1, Q2, Q3, and Q4 in sequence. When the steam intensity value of the steam cooking device 2 is between [Q1, Q4 / 4], the suction force of the range hood 3 is at gear 1; when the steam intensity value of the steam cooking device 2 is in (Q4 / 4, Q4 / 3], the suction force of the range hood 3 is at gear 2; when the steam intensity value of the steam cooking device 2 is in (Q4 / 2, Q4 / 2], the suction force of the range hood 3 is at gear 3; when the steam intensity value of the steam cooking device 2 is in (Q4 / 2, Q4], the suction force of the range hood 3 is at gear 4. In this way, the system can automatically match the gear of the range hood 3 according to the steam cooking device 2, improving the intelligence of the equipment.

[0094] In a preferred embodiment of the present invention, the gear of the range hood 3 is L, where L is less than or equal to N, M, and P. When the cooking stove 1 and the steam cooking device 2 are started simultaneously, T min =E （1,0） +W1; T max =E （N,M）+ W P ; In the formula, T min is the minimum fire intensity when the cooking stove 1 and the steam cooking device 2 are started simultaneously, and T max is the maximum fire intensity when the cooking stove 1 and the steam cooking device 2 are started simultaneously;

[0095] Among them, the fire intensities corresponding to the gears of the range hood 3 from low to high are [T min , T max / L], (T max / L, T max / (L - 1)], (T max / (L - 1), T max / (L - 2)],..., (T max / 3, T max / 2], (T max / 2, T max .

[0096] As Figures 6-7 shown, when the cooking stove 1 and the steam cooking device 2 are started simultaneously, calculate T min and T max, while grouping the fire intensities when the cooker 1 and the steam cooking and roasting device 2 are started simultaneously, and corresponding them to the gears of the range hood 3. Taking the number of cooker gears as 4, the number of gears of the steam cooking and roasting device 2 as 4, and the number of gears of the range hood 3 as 4 as an example, where T min =E （1,0） +W1; T max =E （4,4）+ W4; then when the cooker (1) and the steam cooking and roasting device (2) are started simultaneously, the fire intensities are successively [T min , T max / 4], (T max / 4, T max / 3], (T max / 3, T max / 2], (T max / 2, T max , and the corresponding gears of the range hood 3 are the 1st gear, the 2nd gear, the 3rd gear, and the 4th gear. Through the above process, the corresponding relationship between the gears when the cooker 1 and the steam cooking and roasting device 2 are started simultaneously and the gears of the range hood 3 can be constructed. For example, when both burners of the cooker 1 are at the 1st gear and the steam gear of the steam cooking and roasting device 2 is at the 3rd gear, the system can substitute the above formula and, according to the corresponding relationship between the gears when the cooker 1 and the steam cooking and roasting device 2 are started simultaneously and the gears of the range hood 3, retrieve the gear of the range hood 3 to effectively suck away the fumes generated by the integrated cooker, purify the kitchen air, and improve the intelligence of the equipment.

[0097] In a preferred embodiment of the present invention, by detecting the starting current of the cooker 1 and the starting current value of the steam cooking and roasting device 2, it is determined whether the cooker 1 and the steam cooking and roasting device 2 are started;

[0098] The cooker is provided with a cock valve and a fire signal detection device linked to the cock valve, and the fire gear is judged by the fire signal detection device; the gear of the steam cooking and roasting device 2 is the steam gear set by the user.

[0099] The range hood 3 includes a fan. When the fan speed is lower than the system - required speed or stops rotating, the cooker 1 and the steam cooking and roasting device 2 are turned off.

[0100] In this embodiment, the integrated stove further includes a control system and a circuit board. The integrated stove detects the starting current of the cooking appliance 1 and the steam cooking and baking device 2 through the circuit board. When the circuit board only monitors the starting current of the cooking appliance 1 (0.4E - 0.5E), only the cooking appliance 1 starts; when the circuit board only monitors the starting current value of the steam cooking and baking device 2 (greater than 3E), the steam cooking and baking device 2 starts alone; when the circuit board monitors both the starting current of the cooking appliance 1 and the starting current value of the steam cooking and baking device 2, it means that the cooking appliance 1 and the steam cooking and baking device 2 start simultaneously. The circuit board feeds back the starting signals of the cooking appliance 1 and the steam cooking and baking device 2 received to the control system, and the control system controls the suction hood 3 to turn on.

[0101] The gear position of the cooking appliance 1 is measured through the cock valve on the cooking appliance 1 and the fire signal detection device linked to the cock valve. In this embodiment, the fire signal detection device is a potentiometer, which can also be a displacement sensor. The potentiometer transmits the gear position information to the control system by sensing the rotation angle of the knob on the cock valve. The gear position of the steam cooking and baking device 2 is the gear position set by the user, and the control system can directly obtain it from the program of the steam cooking and baking device 2. Then, according to the starting conditions of the cooking appliance 1 and the steam cooking and baking device 2, the corresponding gear position relationship of the suction hood 3 is selected; moreover, during the use of the cooking appliance 1, the gear positions of the cooking appliance 1 and the steam cooking and baking device 2 are also detected in real time, and the gear position of the suction hood 3 is adjusted in a timely manner according to the gear positions of the cooking appliance 1 and the steam cooking and baking device 2, so as to achieve an efficient and automatic oil fume purification function, improving the kitchen environment and user experience.

[0102] During the operation of the cooking appliance 1 and the steam cooking and baking device 2, if the fan speed in the suction hood 3 is lower than the system - required speed or stops rotating, the cooking appliance 1 and the steam cooking and baking device 2 are turned off to avoid oil fume or steam staying in the kitchen, polluting the kitchen environment and causing discomfort to the user.
