[0025] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0026] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0027] like Figures 1 to 4 As shown, Figure 1 A flow chart of a heat dissipation method for an integrated stove provided by the present invention is shown. Figure 2 A front perspective view of an integrated stove provided by the present invention is shown. Figure 3 A back perspective view of an integrated stove provided by the present invention is shown. Figure 4 A schematic diagram of a heat dissipation channel 21 of an integrated stove provided by the present invention is shown.

[0028] An embodiment of the present invention provides a heat dissipation method for an integrated stove. The integrated stove includes a stove 1, a heat dissipation component 2, a cooking device 3, and a controller 4. The heat dissipation component 2 includes a heat dissipation channel 21 and a heat dissipation fan 22. The air inlet 211 of the heat dissipation channel 21 is arranged between the stove 1 and the cooking device 3. The air outlet of the heat dissipation channel 21 is connected to the inner cavity of the stove 1. The heat dissipation fan 22 is arranged in the heat dissipation channel 21 and is used to supply air entering the heat dissipation channel 21 to the inner cavity of the stove 1. The stove 1, the cooking device 3, and the heat dissipation fan 22 are respectively electrically connected to the controller 4. The heat dissipation method for the integrated stove includes: setting a predetermined off time for the heat dissipation fan 22 in the controller 4; t0; detecting whether the stove 1 and the cooking device 3 are started. If it is detected that one of the stove 1 and the cooking device 3 is started, the detection is stopped and the cooling fan 22 is started. After the cooking device 3 is started, it is detected in real time whether the door 31 of the cooking device 3 is open. If the door 31 is open, the cooling fan 22 is turned off and a timing of t is performed by the controller 4. When t≥t0, detecting whether the cooking device 3 is started. If the cooking device 3 is started, the cooling fan 22 is restarted to prevent steam from entering the air inlet 211. When it is detected that both the stove 1 and the cooking device 3 are turned off, the cooling fan 22 is turned off.

[0029] like Figures 1 to 4As shown, the integrated stove has a split structure. The countertop of the cabinet is opened, and the stove 1 is installed on the countertop of the cabinet, which can avoid disconnecting the countertop of the cabinet to assemble the integrated stove. The cooking device 3 is arranged in the cabinet and is located below the stove 1. A certain gap is provided between the cooking device 3 and the stove 1 for installing the heat dissipation channel 21 of the heat dissipation component 2. The heat dissipation fan 22 is provided on the top of the cooking device 3 and is located in the heat dissipation channel 21. The air inlet 211 of the heat dissipation channel 21 is located between the cooking device 3 and the stove 1. The air outlet of the heat dissipation channel 21 is connected to the inner cavity of the stove 1, so that after entering through the air inlet 211, the air first dissipates the heat generated by the cooking device 3 and then enters the inner cavity of the stove 1 to dissipate the heat generated by the stove 1. The heat dissipation fan 22 provides power for the flow of air. The stove 1 includes a burner and a panel. The panel is provided with a hole for the burner to pass through. When the burner passes through the hole, there is a certain gap between the burner and the panel, which serves as an outlet for air flow. When the air flows, it also provides more oxygen for combustion of the burner.

[0030] As long as it is detected that either the stove 1 or the cooking device 3 is started, the controller 4 controls the cooling fan 22 to start. If only the stove 1 is started, if the stove 1 is turned off, the cooling fan 22 is turned off. When the cooking device 3 is started, the controller 4 controls the cooling fan 22 to start and detects whether the door 31 of the cooking device 3 is open at any time. When the door 31 of the cooking device 3 is opened after the cooking device 3 is started or stopped, a large amount of steam generated by the steaming function of the cooking device 3 flows upward through the air inlet 211 because its density is less than that of air. By detecting that the door 31 of the cooking device 3 is opened and turning off the cooling fan 22 in time, it can be prevented that the steam is sucked into the heat dissipation channel 21 and the inner cavity of the stove 1 under the action of the cooling fan 22, thereby avoiding damage to the circuit components inside the integrated stove.

[0031] Furthermore, a user typically opens door 31 while using cooking device 3 to place some food or seasonings in. This time period can be between 5 and 15 seconds, or longer, preferably 5, 10, or 15 seconds. Therefore, a predetermined shutdown timeout t0 can be set in controller 4 to any time between 5 and 15 seconds. Upon detecting that door 31 is open, controller 4 begins timing t and compares it with t0. When t ≥ t0, controller 4 detects whether cooking device 3 is activated. If cooking device 3 is still operating, controller 4 restarts cooling fan 22, thereby preventing air from entering air inlet 211 during the period when steam escapes when door 31 is open while cooking device 3 remains in operation. Controller 4 detects whether stove 1 and cooking device 3 are closed. When both are closed, controller 4 turns off cooling fan 22, thereby controlling cooling fan 22 to dissipate heat in real time according to the operating status of stove 1 and / or cooking device 3.

[0032] In a preferred embodiment of the present invention, the integrated stove further includes a first current sensor provided in the circuit of the stove 1, the first current sensor being used to detect the circuit current I of the stove 1. 灶1 The first current sensor is connected to the controller 4 for communication, and detects whether the stove 1 and the cooking device 3 are started. If it is detected that one of the stove 1 and the cooking device 3 is started, the detection is stopped and the cooling fan 22 is started. The first current sensor detects whether the stove 1 is started. If the stove 1 is started, the cooling fan 22 is started. The controller 4 sets the starting current I of the stove 1. 灶启 , I 灶启 is 0.4A to 0.5A; the first current sensor transmits the current to the controller 4 I 灶1 with I 灶启 Compare; if I 灶1 =I 灶启 , the cooling fan 22 is started.

[0033] The starting current I of the cooker 1 is set in the controller 4. 灶启 , turn on the first current sensor to detect the circuit current of the cooker 1 in real time. Usually, the circuit current of the cooker 1 when it is started is slightly larger than the current when it is working. Once the startup current I 灶1 When the current is between 0.4A and 0.5A, the controller 4 starts the cooling fan 22 regardless of whether the cooking device 3 is started or not.

[0034] In a preferred embodiment of the present invention, the integrated stove further includes a second current sensor provided in the circuit of the cooking device 3, the second current sensor being used to detect the circuit current I of the cooking device 3 in real time. 烹饪1 The second current sensor is connected to the controller 4 for communication, and detects whether the cooker 1 and the cooking device 3 are started. If it is detected that one of the cooker 1 and the cooking device 3 is started, the detection is stopped and the cooling fan 22 is started. The second current sensor also includes detecting whether the cooking device 3 is started if the cooker 1 is not started, and starting the cooling fan 22 if the cooking device 3 is started. The cooking device 3 startup current I is set in the controller 4. 烹饪启 , I 烹饪启 is 3A; if I 灶1 =0, turn on the second current sensor and transmit the I 烹饪1 with I 烹饪启 Compare; if I 烹饪1 ≥I 烹饪启 , the cooling fan 22 is started.

[0035] The starting current I of the cooking device 3 is set in the controller 4. 烹饪启 , turn on the second current sensor to detect the circuit current of the cooking device 3 in real time. Usually, the circuit current of the cooking device 3 when it is started will be greater than 3A, so the starting current I烹饪启 Set to 3A, once the cooking device 3 is detected, the current I 烹饪1 When the voltage is greater than 3A, the controller 4 starts the cooling fan 22 regardless of whether the cooker 1 is started or not, and detects in real time whether the door 31 of the cooking device 3 is open or closed.

[0036] In a preferred embodiment of the present invention, when it is detected that both the stove 1 and the cooking device 3 are turned off, turning off the cooling fan 22 includes: turning on the first current sensor and the second current sensor to respectively detect the real-time current I of the stove 1. 灶2 and the real-time current I of the cooking device 3 烹饪2 ;if I 灶2 =0,I 烹饪2 ≠0, then when the door 31 of the cooking device 3 is detected to be open, the cooling fan 22 is turned off and the cooling fan 22 is restarted after t0 time and the real-time current I of the cooking device 3 is continuously detected. 烹饪2 , if I 烹饪2 =0, then turn off the cooling fan 22; if I 灶2 ≠0, I 烹饪2 =0, continuously detect the circuit current I of cooker 1 灶2 , if I 灶2 =0, the cooling fan 22 is turned off.

[0037] The first current sensor and the second current sensor are turned on at the same time. The first current sensor is used to detect the real-time current I of the cooker 1. 灶2 The second current sensor is used to detect the real-time current I of the cooking device 3. 烹饪2 , when I 灶2 =0 and I 烹饪2 = 0, it is considered that the stove 1 and the cooking device 3 are both in the off state, and the controller 4 turns off the cooling fan 22; when I 灶2 ≠0 and I 烹饪2 = 0, it is considered that the cooking device 3 is turned off and the stove 1 is still working, and the controller 4 switches to the heat dissipation program of the stove 1, that is, continuously detecting the circuit current I of the stove 1 灶2 Until I 灶2 = 0 when the controller 4 turns off the cooling fan 22; when I 灶2 =0 and I 烹饪2 ≠0, it is considered that the cooker 1 is turned off and the cooking device 3 is still working. The control area switches to the cooling program of the cooking device 3, that is, it detects whether the door 31 of the cooking device 3 is open. If so, the cooling fan 22 is turned off and then restarted after t0 time and the real-time current I of the cooking device 3 is continuously detected. 烹饪2 Until I 烹饪2 =0, the controller 4 turns off the cooling fan 22.

[0038] In a preferred embodiment of the present invention, the integrated stove also includes a temperature sensor arranged in the heat dissipation channel 21, the temperature sensor is used to detect the ambient temperature T in the heat dissipation channel 21, the temperature sensor is communicated with the controller 4, and when it is detected that the stove 1 and the cooking device 3 are both turned off, the heat dissipation fan 22 is turned off, including: setting the maximum value T0 of the ambient temperature in the controller 4; if the stove 1 and the cooking device 3 are both turned off, turning on the temperature sensor, and comparing T transmitted to the controller 4 with T0; if T<T0, turning off the heat dissipation fan 22.

[0039] After the first and second current sensors detect that both cooker 1 and cooking device 3 are turned off, the temperature sensor is activated to detect ambient temperature T within heat dissipation channel 21 and transmits the detected ambient temperature to controller 4. Controller 4 then compares ambient temperature T with its internally set maximum ambient temperature T0. If T < T0, the ambient temperature within the integrated cooker has dissipated below the preset maximum ambient temperature T0, completing heat dissipation. Controller 4 then turns off cooling fan 22. Preferably, the maximum ambient temperature T0 is set at 55°C.

[0040] In a preferred embodiment of the present invention, the integrated stove includes a firepower detector electrically connected to the controller 4. If the stove 1 is started, starting the cooling fan 22 includes: the stove 1 is started, and the cooling fan 22 is started at the maximum speed; the firepower level of the stove 1 is set in the controller 4, and the speed n1 of the cooling fan 22 corresponding to the firepower level is set; the firepower detector detects the firepower level of the stove 1, and the controller 4 adjusts the speed of the cooling fan 22 to n1 according to the firepower level.

[0041] like Figures 2 to 4 As shown, when it is detected that the stove 1 is started, the cooling fan 22 rotates at the maximum speed by default, and the controller 4 sets the fire power gears of the stove 1 from small to large as the first fire power gear, the second fire power gear, the third fire power gear, the fourth fire power gear and the fifth fire power gear, and the speed of the cooling fan 22 is set in the controller 4, including the first speed gear corresponding to the first fire power gear, the second speed gear corresponding to the second fire power gear, the third speed gear corresponding to the third fire power gear, the fourth speed gear corresponding to the fourth fire power gear and the fifth speed gear corresponding to the fifth fire power gear. After the stove 1 is started, the fire power gear of the stove 1 is detected by the fire detector and a signal is transmitted to the controller 4, and the controller 4 adjusts the speed of the cooling fan 22 to the speed gear corresponding to the fire power gear.

[0042] In a preferred embodiment of the present invention, the fire detector is a flame discriminator 5, which is arranged above the stove 1 to detect the flame height H of the stove 1. The flame discriminator 5 is electrically connected to the controller 4. The controller 4 is set with a fire level corresponding to the range of the flame height H to determine the fire level of the stove 1 based on the information from the flame discriminator 5.

[0043] like Figure 2 and Figure 3 As shown, when the fire power control of the stove 1 is set by pressing a button or touching a key, the fire power detector can be a flame detector 5. The flame detector 5 is arranged above the stove 1 so that the camera of the flame detector 5 faces the flame. The flame height H is obtained to determine which fire power level the stove 1 is in. The larger the flame height H, the higher the fire power level. The flame height H corresponding to each fire power level is set in the controller 4, so that the controller 4 can directly determine which fire power level the stove 1 is in through the obtained flame height H.

[0044] In a preferred embodiment of the present invention, the stove 1 includes a stopcock 11 for adjusting the firepower. The firepower detector is a potentiometer, which is arranged at the stopcock 11. The potentiometer is electrically connected to the controller 4 to determine the firepower level of the stove 1 by the resistance value generated by the rotation of the stopcock 11.

[0045] like Figure 2 and Figure 3 As shown, when the fire power control of the stove 1 is adjusted by the stopcock 11, the stopcock 11 includes a potentiometer that is communicatively connected to the controller 4. The potentiometer serves as a fire power detector. It generates different resistance values during the rotation of the stopcock 11 and transmits a signal to the controller 4. The controller 4 can then obtain the fire power level of the stove 1.

[0046] In a preferred embodiment of the present invention, the integrated stove also includes a detection element arranged on the cooling fan 22, which is communicated with the controller 4 to detect the rotational speed n of the cooling fan 22 and transmit it to the controller 4. The controller 4 compares the rotational speed n with n1. If n<n1 or n=0, the controller 4 turns off the stove 1 and the cooking device 3.

[0047] Among them, the detection element is preferably a Hall-type speed sensor, which includes a Hall switch integrated sensor and a magnetic turntable. The input shaft of the magnetic turntable is connected to the fan shaft of the cooling fan 22. When the fan shaft rotates, the magnetic turntable rotates accordingly. The Hall switch integrated sensor fixed near the magnetic turntable can generate a corresponding pulse when each small magnet on the magnetic turntable passes. By detecting the number of pulses per unit time, the speed of the cooling fan 22 can be obtained. Several speeds n1 corresponding to the firepower gears are set in the controller 4. For example, the firepower gears of the stove 1 include a first firepower gear from low to high, a second firepower gear, a third firepower gear, a fourth firepower gear, and a fifth firepower gear. Correspondingly, the speed gears of the cooling fan 22 also include a first speed gear, a second speed gear, a third speed gear, a fourth speed gear, and a fifth speed gear from light wind to strong wind. When the stove 1 is in the third firepower gear, the cooling fan 22 should be in the corresponding third speed gear. The real-time speed n of the cooling fan 22 is detected by the detection element, and n is compared with the speed n1 of the third speed gear by the controller 4. When n<n1 or n=0, it indicates that the cooling fan 22 has a fault, and the controller 4 promptly shuts down the stove 1 and / or the cooking device 3 to prevent the circuit components in the stove 1 or the cooking device 3 from being damaged due to high temperature.

[0048] In a preferred embodiment of the present invention, the cooking device 3 includes a micro switch 32 that is communicatively connected to the controller 4. The micro switch 32 is arranged at a corresponding position of the door 31. The closing or opening of the door 31 triggers the micro switch 32 to transmit a signal to the controller 4.

[0049] like Figure 4 As shown, the micro switch 32 includes a switch body and an action reed. The switch body is communicatively connected to the controller 4. The action reed is elastically connected to the switch body. A fixed contact is provided on the switch body, and a moving contact is provided on the action reed. When the door 31 is closed, force is applied to the action reed. When the action reed is displaced to the critical point, an instantaneous action is generated, causing the moving contact and the fixed contact to be quickly connected or disconnected, thereby allowing the controller 4 to obtain the status information of whether the door 31 is closed or open.

[0050] The heat dissipation method of the integrated stove of the present invention sets a predetermined shutdown time t0. When the user opens the door 31 while the cooking device 3 is working, the controller 4 starts timing, and the time is t. When t≥t0 and the cooking device 3 is still working, the controller 4 restarts the heat dissipation fan 22, which can prevent the steam overflowing in a short time when the user opens the door 31 of the cooking device 3 from entering the interior of the integrated stove through the air inlet 211 through the action of the heat dissipation fan 22, thereby preventing a large amount of steam from entering the interior of the integrated stove and causing damage to the electrical components; the first current sensor is set in the circuit of the stove 1, and the second current sensor is set in the circuit of the cooking device 3. By detecting the current between the stove 1 and the cooking device 3, the heat dissipation fan 22 is turned off. The current of the cooking device 3 can timely obtain the working status of the stove 1 and the cooking device 3, so as to implement the corresponding heat dissipation strategy according to the actual working status of the integrated stove; the temperature sensor arranged in the heat dissipation channel 21 detects the ambient temperature in the integrated stove and controls the delayed shutdown time of the heat dissipation fan 22, which can speed up the heat dissipation speed of the integrated stove after use and avoid the electrical components in the integrated stove being at a high temperature for a long time; by detecting the heat dissipation fan 22, it is determined whether the heat dissipation fan 22 is in the corresponding fire level, so that it is possible to obtain whether the heat dissipation fan 22 is faulty earlier, thereby minimizing the damage of the circuit components inside the integrated stove due to high temperature.

[0051] An integrated stove according to an embodiment of the present invention dissipates heat by the aforementioned integrated stove heat dissipation method.
