Detailed Implementation

[0056] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference. Figure 1 The side containing the top wall 11 is defined as "upper," and the position of the cleaning component 5 is defined as "left."

[0057] An integrated stove proposed in this invention embodiment, see [link to relevant documentation]. Figures 8-12As shown, it includes a lightwave cooking oven 100, a main body 200, a cooking head 400, and an oil collection box 500.

[0058] In this embodiment, the light wave cooking oven 100 and the oil collection box 500 are arranged vertically within the body 200. The light wave cooking oven 100 includes an inner liner 1, a control system, a heating component, a cleaning component 5, and a hot air circulation device 6. The heating component includes a light-transmitting glass 2, a reflector 3, and a light wave heating tube 4.

[0059] Furthermore, the inner liner 1 is a box with its opening facing forward. The inner liner 1 includes a top wall 11, a bottom wall 12, a left side wall 13, a right side wall 14, and a rear side wall 15. The top wall 11, bottom wall 12, left side wall 13, right side wall 14, and rear side wall 15 form a hollow cooking cavity 10. An installation opening is provided on the top wall 11 of the inner liner 1. A light-transmitting glass 2 is installed at the installation opening, and a reflector 3 is fixed above the installation opening. The light-transmitting glass 2 and the reflector 3 form an installation cavity 30. A light wave heating tube 4 is installed inside the installation cavity 30. A water collection trough 121 is also formed on the bottom wall 12. A drain outlet 122 is provided at the bottom of the water collection trough 121. The drain outlet 122 is in fluid communication with the oil collection box 500.

[0060] It should be noted that the inner liner 1 of the cooking oven 100 is equipped with a light-transmitting glass 2, a reflector 3, and a light wave heating tube 4 at the top to achieve light wave heating of food. The light-transmitting glass is preferably made of microcrystalline glass, and the light wave heating tube 4 is preferably made of carbon fiber heating tube, halogen heating tube, or graphene heating tube.

[0061] It should also be noted that the cooking oven 100 includes a frame 7 and a door 8. The inner liner 1 is fixed inside the frame 7, and the door 8 is hinged to the front opening of the inner liner 1. The frame 7 includes an upper plate 71 and a lower plate 72 spaced apart vertically, a panel 73 connected to the front opening of the inner liner 1, and a support plate 74 connecting the upper plate 71 and the lower plate 72.

[0062] Furthermore, the cleaning assembly 5 is connected to the lightwave cooking oven 100 and is capable of spraying water towards the lightwave cooking oven 100 for cleaning. The cleaning assembly 5 includes a water supply device 51, a water pump 52, a steam generator 53, and nozzles. The steam generator 53 has a water inlet in fluid communication with the water supply device 51 and a steam outlet in communication with the cooking chamber 10. The nozzle is fixed on the inner liner 1 and has a water inlet located outside the inner liner 1 and a spray outlet located inside the cooking chamber 10 and facing the light-transmitting glass 2. The suction port of the water pump 52 is connected to the water supply device 51, and the drain port 122 is connected to the water inlet of the nozzle. The cleaning assembly 5 also includes a first valve body 54, a second valve body 55, a third valve body 56, and a fourth valve body 59, and multiple nozzles, including a first nozzle 57 and a second nozzle 58. Specifically, the first valve body 54 is installed on the pipeline between the water pump 52 and the inlet of the steam generator 53 to control whether water is supplied to the steam generator 53; the second valve body 55 is installed on the pipeline between the water pump 52 and the first nozzle 57 to control whether water is supplied to the first nozzle 57; the third valve body 56 is installed on the pipeline between the water pump 52 and the second nozzle 58 to control whether water is supplied to the second nozzle 58. The fourth valve body 59 is installed between the drain port 533 and the oil collection box 500, and can control the pipeline between the drain port 533 of the steam generator 53 and the oil collection box 500.

[0063] It should be noted that the steam generator 53 has a water inlet 531, a steam outlet 532, and a drain outlet 533. The first valve body 54 controls the connection between the water pump 52 and the water inlet 531 of the steam generator 53; the second valve body 55 controls the connection between the water pump 52 and the first nozzle 57; the third valve body 56 controls the connection between the water pump 52 and the second nozzle 58; and the fourth valve body 59 is located between the drain outlet 533 and the oil collection box 500, and can control the connection between the drain outlet 533 of the steam generator 53 and the oil collection box 500, so as to discharge the residual water inside the steam generator 53 after it has finished working.

[0064] In addition, the first nozzle 57 and the second nozzle 58 are fixed on the opposite left side wall 13 and right side wall 14 of the inner liner 1, respectively, and the water spraying direction of the first nozzle 57 and the second nozzle 58 is towards the light-transmitting glass 2.

[0065] Furthermore, a hot air circulation device 6 is provided on the left side wall 13 and / or right side wall 14 of the inner liner 1. The hot air circulation device 6 has a hollow hot air cavity 60. A hot air baffle 63 with multiple openings is provided between the hot air cavity 60 and the cooking cavity 10. A hot air heating pipe 61 and a hot air fan 62 are provided inside the hot air cavity 60. The hot air fan 62 drives the gas flow between the hot air cavity 60 and the cooking cavity 10. An exhaust passage communicating with the outside is provided on the inner liner 1 to exhaust the hot steam in the cooking cavity 10.

[0066] See Figure 9As shown, a recessed water collection trough 121 is formed on the bottom wall 12 of the inner liner 1, and a drain outlet 122 is provided at the bottom of the water collection trough 121. Wastewater generated during the cleaning process will collect in the water collection trough 121 and be discharged into the oil collection box 500 through the drain outlet 122 at the bottom.

[0067] See Figure 6 As shown, the microwave cooking oven 100 also includes a control system, which includes a control board and electrically connected door detection device, an internal temperature sensor, a steam generator temperature sensor, and an oil level detection device. The panel 73 of the frame 7 of the cooking oven 100 is equipped with a door detection device for detecting whether the door 8 is closed. This device typically has a telescopic rod structure and a microswitch. When the door 8 is closed, the telescopic rod is pushed, triggering the microswitch, and the signal from the microswitch is transmitted back to the control board.

[0068] In addition, an internal cavity temperature sensor is fixed on the inner liner 1, which is generally a thermocouple or thermistor temperature sensor, to transmit the internal cavity temperature signal back to the control board.

[0069] In addition, the temperature sensor of the steam generator is generally a thermocouple or thermistor temperature sensor fixed at the bottom of the steam generator 53 with heating tubes installed. When there is a lack of water in the steam generator 53, the temperature at the bottom of the steam generator 53 will rise rapidly. The controller determines whether there is a lack of water based on the temperature signal. If there is a lack of water, the steam generator 53 is stopped, the first valve body 54 is opened, and the water pump 52 is started so that the water pump 52 supplies a certain amount of water into the steam generator 53. Then the water pump 52 is stopped and the first valve body 54 is closed.

[0070] Finally, the oil level detection device is installed inside the integrated stove body 200. It typically uses an elastic support device with a microswitch. The oil collection box 500 is partially supported on the oil level detection device. When the liquid in the oil collection box 500 increases to a certain level, the oil collection box 500, under the action of gravity, pushes the elastic support device of the oil level detection device and actuates the microswitch. The control board detects this signal and determines that the oil collection box 500 is full, then issues a buzzer and text alarm, and simultaneously stops the water pump 52. One integrated stove uses a light wave heating component installed at the top of the inner tank for light wave heating. Light wave heating provides better heating uniformity, and the inner tank has no dead corners for cleaning, making it easy to clean. Nozzles spray water onto the translucent glass for cleaning, reducing the workload of manual cleaning.

[0071] On the other hand, an automatic cleaning method for a microwave cooking oven is provided, based on a microwave cooking oven 100 on an integrated cooktop. The microwave cooking oven 100 includes a control system, a heating element, and a cleaning element 5. The method includes the following steps:

[0072] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in step S1, the control system receives a cleaning command and checks whether the door 8 of the lightwave cooking oven 100 is closed. Specifically, a door detection device is used to detect the opening and closing of the door 8. This device typically has a telescopic rod structure and a microswitch. When the door 8 is closed, the telescopic rod is pushed, triggering the microswitch, and the signal from the microswitch is transmitted back to the control board.

[0073] S2. When the door 8 is closed, the steam generator 53 in the cleaning assembly 5 is activated and steam is supplied to the inner pot 1 of the microwave cooking oven 100, so that the steam adheres to the stains on the inner wall of the inner pot 1 of the microwave cooking oven 100, and the stains can absorb the steam and soften them.

[0074] Furthermore, S2 includes the following steps:

[0075] S21. Before starting the steam generator 53, open the first valve body 54 located between the water pump 52 and the steam generator 53, start the water pump 52 so that the water pump 52 supplies a certain amount of water into the steam generator 53, and then stop the water pump 52 and close the first valve body 54.

[0076] S22. Start the steam generator 53 to supply steam to the inner liner 1. Specifically, the steam supply time in S22 is a first predetermined time Δt1. When the steam supply time reaches the first predetermined time Δt1, close the first valve body 54 and stop the steam generator 53. For example: detect the temperature T inside the inner liner 1. N By controlling the heating power of the steam generator 53 or starting / pausing it, the temperature T inside the inner liner 1 is adjusted. N The steam generator 53 is stopped after maintaining the first preset temperature range ΔT1 (generally 90-100℃) for a predetermined time Δt1 (e.g., 5 minutes).

[0077] S23. Detect the internal temperature T of inner liner 1. N By controlling the heating power or starting / pausing the steam generator 53, the internal temperature T of the inner liner 1 is adjusted. N Maintain within the first preset temperature range ΔT1.

[0078] S3. After softening for a specified time, activate the nozzle in the cleaning component 5 to spray water onto the light-transmitting glass 2 of the lightwave cooking box 100 to rinse away the softened stains from S2.

[0079] Furthermore, S3 includes the following steps:

[0080] S31. Open the second valve body 55 located between the water pump 52 and the first nozzle 57, keep the third valve body 56 located between the water pump 52 and the second nozzle 58 closed, start the water pump 52, and spray water towards the light-transmitting glass 2 through the first nozzle 57.

[0081] Furthermore, in S31, the water spraying time of the first nozzle 57 toward the light-transmitting glass 2 is a third predetermined duration Δt3 (e.g., 3 seconds).

[0082] Following S31, S32 is also included: when the water spraying time reaches the third predetermined duration Δt3, the third valve body 56 is opened and the second valve body 55 is closed, and water is sprayed towards the light-transmitting glass 2 through the second nozzle 58 for water spraying and rinsing, and the water spraying time is the third predetermined duration Δt3, for example, 3 seconds.

[0083] It should be noted that by alternating flushing with the first nozzle 57 and the second nozzle 58, the cumulative spraying time of the two nozzles reaches a second predetermined duration Δt2, for example, 30 seconds, and Δt3 < Δt2. Then, the water pump 52, the second valve body 55, and the third valve body 56 are shut off.

[0084] Furthermore, the control system also includes an oil level detection device, which can detect in real time whether the oil collection box 500 is full. If the oil collection box 500 is full, the water pump 52 will be stopped and a cleaning prompt will be issued.

[0085] An automatic cleaning method for a lightwave cooking oven involves using steam generated by a steam generator 53 to soften solid stains inside the inner pot, improve the fluidity of grease, and reduce the adhesion of stains. Then, water is sprayed onto the transparent glass 2 using a nozzle to clean the stains, making it easy to remove them.

[0086] Example 2:

[0087] See Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, based on Example 1, a separate step is added:

[0088] S4. After rinsing the stains, start the hot air circulation device 6 to heat and dry the inner liner 1. It should be noted that after rinsing process S3 is completed, the hot air circulation device 6 is started to dry the inner liner 1, maintaining the temperature T of the inner liner 1. N The system reaches the second preset temperature range ΔT2 (generally 120-200℃) and runs for the fourth preset time Δt6 (e.g., 5 minutes). During the drying process, the light wave heating tube 4 can also be activated to improve the drying speed and effect.

[0089] Example 3:

[0090] See Figure 7 As shown, unlike Embodiment 1, the cleaning assembly 5 includes a water supply device 51 and a steam generator 53 disposed outside the inner tank 1, a nozzle disposed on the side wall of the inner tank 1, a water pump 52 disposed between the water supply device 51 and the nozzle, a water pump 52' disposed between the steam generator 53 and the water supply device 51, a first valve body 54 disposed between the water pump 52 and the water supply device 51, a first connecting valve body 54' disposed between the drain outlet 122 of the light wave cooking oven 100 and the water pump 52, and a second connecting valve body 59' disposed between the oil collection box 500 and the drain outlet of the light wave cooking oven 100.

[0091] The nozzles are multiple, including a first nozzle 57 and a second nozzle 58. The cleaning assembly 5 also includes a second valve body 55 disposed between the water pump 52 and the first nozzle 57, and a third valve body 56 disposed between the water pump 52 and the second nozzle 58. S3 further includes the following steps:

[0092] Open the first valve body 54 to connect the water supply device 51 and the water pump 52, while keeping the first connecting valve body 54' and the second connecting valve body 59' closed.

[0093] Open the second valve body 55, keep the third valve body 56 closed, start the water pump 52, and spray water towards the light-transmitting glass 2 through the first nozzle 57.

[0094] Open the third valve body 56 and close the second valve body 55, and spray water towards the light-transmitting glass 2 through the second nozzle 58.

[0095] Water pump 52' is installed on the pipeline between the water supply device 51 and the inlet of the steam generator 53 to control whether water is supplied to the steam generator 53;

[0096] The first valve body 54 is disposed between the water supply device 51 and the water pump 52 to control the water pump 52 to draw water from the water supply device 51 and spray it into the inner tank 1 through the first nozzle 57 and the second nozzle 58.

[0097] A first connecting valve body 54' is disposed between the drain outlet 122 of the inner tank 1 and the water pump 52, to control the water pump 52 to draw water from the water collection tank 121 of the inner tank 1 and spray it into the inner tank 1 through the first nozzle 57 and the second nozzle 58. A second valve body 55 is disposed on the pipeline between the water pump 52 and the first nozzle 57, to control whether water is supplied to the first nozzle 57. A third valve body 56 is disposed on the pipeline between the water pump 52 and the second nozzle 58, to control whether water is supplied to the second nozzle 58. An oil collection box 59' is disposed between the drain outlet 122 of the inner tank 1 and the oil collection box 500, to control the drainage of water from the inner tank 1 after cleaning into the oil collection box 500.

[0098] Furthermore, after the first nozzle 57 and the second nozzle 58 alternately flush for a cumulative period of Δt4, the first connecting valve body 54' is opened and the first valve body 54 is closed to perform circulating water spraying. After the first nozzle 57 and the second nozzle 58 alternately flush for a cumulative period of Δt2, the water pump 52 is turned off, and the first connecting valve body 54', the second valve body 55, the third valve body 56, or the second connecting valve body 59' is opened to drain water. After the predetermined drainage period of Δt5 is reached, the first connecting valve body 54', the second valve body 55, the third valve body 56, and the second connecting valve body 59' are closed.

[0099] Furthermore, unlike Embodiments 1 and 2, S3 further includes the following steps:

[0100] Open the first valve body 54 located between the water pump 52 and the water supply device 51 to connect the water supply device 51 and the water pump 52, and keep the first connecting valve body 54' located between the drain outlet 122 of the light wave cooking box 100 and the water pump 52 and the second connecting valve body 59' located between the oil collection box 500 and the drain outlet of the light wave cooking box 100 closed;

[0101] Open the second valve body 55, keep the third valve body 56 closed, start the water pump 52, and spray water towards the light-transmitting glass 2 through the first nozzle 57.

[0102] Open the third valve body 56 and close the second valve body 55, and spray water towards the light-transmitting glass 2 through the second nozzle 58.

[0103] Furthermore, after the first nozzle 57 and the second nozzle 58 alternately flush for a cumulative period of a fourth predetermined time Δt4 (Δt3<Δt4<Δt2), the first connecting valve body 54' is opened and the first valve body 54 is closed to perform circulating water spraying.

[0104] After the water is flushed alternately by the first nozzle 57 and the second nozzle 58 for a cumulative second predetermined time Δt2 (Δt3 < Δt2), the water pump 52 is turned off, and the first connecting valve body 54', the second valve body 55, the third valve body 56 or the second connecting valve body 59' is opened to drain water. After the predetermined drainage time Δt5 is reached, the first connecting valve body 54', the second valve body 55, the third valve body 56 and the second connecting valve body 59' are closed.

[0105] Furthermore, the difference from Examples 1 and 2 is the addition of a circulating spray system for the water inside the inner tank 1.

[0106] A separate water pump 52' is added to supply water to the steam generator 53. Specifically, a circulating water pipeline is added between the drain outlet 122 of the inner tank 1 and the inlet of the water pump 52. Switching between the first valve body 54 and the first connecting valve body 54' allows the water pump 52 to draw clean water from the water supply device 51 and circulating water from the inner tank 1. A second connecting valve body 59' is also connected to the circulating water pipeline at the drain outlet 122. This second connecting valve body 59' is opened after cleaning to drain all the wastewater from the inner tank 1 and the pipeline into the oil collection box 500.

[0107] An automatic cleaning method for a microwave oven utilizes steam generated by a steam generator 53 to soften solid stains inside the inner liner, improve grease fluidity, and reduce stain adhesion. Water is then sprayed onto the translucent glass 2 using a nozzle for cleaning, making it easier to remove stains. This method solves the problem of poor heating uniformity. Furthermore, after cooking, the exposed heating element creates blind spots during cleaning, making cleaning difficult.
