Description

Smart cooking machine Technical Field

[0001] The present invention relates to an intelligent cooking machine, in particular to an intelligent cooking machine which uses microwave heating as an auxiliary heat source. Background Art

[0002] Existing intelligent cooking machines consist of a frame, a sealed cavity, a wok assembly, and a feeding device. Dishes cooked by such intelligent cooking machines according to set programs are comparable to stir-fried dishes cooked by chefs, but they still have the following shortcomings:

[0003] 1. Since the existing intelligent cooking machine adopts a single heating method, its heating efficiency is not high, resulting in a long time required to cook a dish.

[0004] 2. When cooking light and large vegetarian ingredients, relying solely on heat conduction can easily result in the dishes being undercooked.

[0005] 3. When cooking meat ingredients, if the heating power is high, if the cooking time is too short, the outside of the ingredients may be cooked but the inside may be raw. If the cooking time is too long, the outside of the ingredients may be cooked but the outside may be burnt. Technical issues

[0006] The technical problem solved by the present invention is to provide an intelligent cooking machine which can effectively improve cooking efficiency and cooking quality and shorten the time difference between the inside and outside of cooked ingredients. Technical Solutions

[0007] In order to solve the above technical problems, the present invention provides an intelligent cooking machine, which includes a sealed cavity for installing a wok assembly. The wok assembly consists of a wok, a furnace core for heating the wok, and a lid that can cover the mouth of the wok. When the wok containing ingredients rotates and is sealed with the lid above it, at least one group of microwave generators installed on the lid feeds microwaves into the ingredients in the wok.

[0008] Preferably, the microwave generator feeds microwaves into the pot through at least one waveguide tube, and a waveguide cover is provided at the outlet of the waveguide tube.

[0009] Preferably, a smoke exhaust pipe is provided on the pot cover to discharge the oil smoke generated in the frying pan to the oil smoke treatment device, and an isolation structure is provided in the smoke exhaust pipe to prevent microwaves from leaking outward with the wind.

[0010] Preferably, a fork is provided in the wok, which can stir the ingredients up and down and rotate relative to the wok.

[0011] Preferably, a sealing structure is provided between the pot cover and the pot mouth to prevent microwave leakage.

[0012] Preferably, the control circuit is further provided with a control module for disconnecting the working power supply of the magnetron in the microwave generator when a cover-opening signal is sent to the pot lid or frying pan.

[0013] Preferably, a touch switch is provided between the pot cover and the pot mouth, which cuts off the power to the control circuit of the microwave generator when the pot cover leaves the pot mouth.

[0014] Preferably, a microwave leakage detection device is provided near the outside of the pot cover and in the smoke exhaust duct, and the microwave leakage detection device is electrically connected to the microwave radiation alarm device of the control circuit. Beneficial effects

[0015] Existing cooking machines typically use a single heating method, typically conductive heating or electromagnetic coil heating. This single heating method can lead to prolonged cooking times and poor cooking quality. The present invention, based on the primary electromagnetic heating method, incorporates a microwave heating assembly, which is mounted on the lid of the pot, which does not need to be removed. The microwaves generated by the microwave heating assembly are fed directly or through at least one waveguide into the food being stir-fried and rotating with the pot. This structure offers the advantage of evenly heating the food both inside and out, significantly shortening cooking time and resulting in dishes that are both fragrant and tender on the inside.

Best Mode for Carrying Out the Invention

[0020] As shown in Figure 1, the intelligent cooking machine of the present invention includes a casing 10, a sealed cavity 100 is provided in the casing 10 (the sealed cavity 100 is enclosed by an inner casing 20 arranged in the casing 10 and open at the front side and a door panel 11 of the cooking machine), a wok assembly, a wok lifting device 70, a feeding device 60, a wok station control device 80, an oil fume treatment device 80 and a main control device.

[0021] The wok assembly comprises a wok 40, a furnace core 30 for heating the wok 40, and a lid 50 that fits over the wok 40. The furnace core 30 comprises an inner cover, a heating assembly, and an outer cover. Preferably, the inner cover has an open top and a flat bottom. The vertical cross-section of the inner cover is arcuate, identical to the arcuate cross-section of the lower half of the wok 40. The heating assembly comprises an electromagnetic coil and several fixings. The electromagnetic coil surrounds the outer wall of the inner cover and is secured to the inner cover via the fixings. The outer cover is a cylindrical structure with an open top. The wok 40 is housed within the inner cover and can rotate relative to the furnace core 30 about its central axis.

[0022] The pot cover 50 is arranged in the sealed cavity 100 and placed at the rear upper part of the sealed cavity 100. The stove core 30 can move the pot mouth of the wok 40 toward the pot cover 50 through the wok lifting device 70 and is mounted in the sealed cavity 100 in a sealed cover manner with the pot cover 50; the feeding device 60 is used to put food into the wok 40. It is arranged in the sealed cavity 100 and is located above the wok 40; the wok position control device 80 is used to fix the stove core 30 on the wok lifting device 70, and control the flipping of the stove core 30 to make the pot mouth of the wok 40 face the corresponding position (such as the pot mouth facing the pot cover position, the pot mouth facing the feeding device 60 position and the pot mouth facing the dish serving position, etc.) to perform corresponding operations.

[0023] The oil fume treatment device 80 is arranged in the interlayer formed by the casing 10 and the inner casing 20, and a smoke exhaust port is provided on the pot cover 50. The smoke exhaust port is connected to the oil fume treatment device 80 through a smoke exhaust pipe to discharge the oil fume generated in the wok 40 to the oil fume treatment device 80 for treatment and then discharged out of the sealed cavity 100 or discharged back into the sealed cavity 100 for circulation treatment.

[0024] On the basis of the heating of the furnace core 30, the present invention adds microwave heating as an auxiliary heat source to provide heat energy for the wok 40 to compensate for the loss or insufficient heating of the electromagnetic coil during high-power heating. The rapid heating method of microwaves is used as auxiliary heating, which greatly improves the cooking efficiency and solves the problem of inconsistent doneness of the inside and outside of the ingredients during the cooking process of the traditional single heating method. The following is a detailed explanation in conjunction with the specific implementation method.

[0025] As shown in Figures 2-3, the pot cover 50 is made of microwave-insulating material and includes a rotating disk assembly and a pot cover assembly. The rotating disk assembly is coaxially arranged with the pot cover assembly. The rotating disk assembly is composed of an upper fixed disk 51 and a lower fixed disk 52. The pot cover body 53 of the pot cover assembly is rotatable and sandwiched between the upper fixed disk 51 and the lower fixed disk 52. A through hole is provided on the rear side of the inner shell 20 to match the upper fixed disk 51. The outer side of the upper fixed disk 51 (the side facing the lower fixed disk 52 is the inner side, and the opposite side is the outer side) passes through the through hole and is fixed in the through hole by a mounting bracket provided on the rear outer wall of the inner shell 20, thereby fixing the entire pot cover 50 rotating assembly to the rear side of the inner shell 20.

[0026] At least one group of microwave generators 1 is provided on the outer side of the upper fixed plate 51. The microwave generators 1 feed microwaves into the wok 40 through at least one waveguide 2. The microwave energy emitted by the microwave generator 1 enters the wok 40 from one end of the waveguide 2 and then passes through the upper fixed plate 51 and the lower fixed plate 52 at the other end. A waveguide cover 3 is also provided at the other end of the waveguide 2 to prevent water vapor, oil smoke, etc. from entering the waveguide 2 during cooking and then contaminating the microwave generator. The waveguide cover 3 can be made of microwave-transmissive material and is a food-grade material.

[0027] The microwave generator 1 may also feed microwaves into the frying pan 40 through other waveguide structures, such as by providing waveguide channels on the upper fixed plate 51 and the lower fixed plate 52 .

[0028] When the wok 40 containing the food rotates and is sealed with the pot cover assembly, the microwave generator 1 feeds microwaves into the food in the wok 40 .

[0029] By installing the microwave generator 1 on the fixed part of the pot cover 50 and feeding microwaves into the rotating wok 40, and the wok 40 and the pot cover 50 are covered to form a closed cooking cavity, the microwaves are reflected back and forth in the closed cooking cavity and pass through or through the food, thereby achieving rapid heating of the food. At the same time, the main control circuit controls the wok 40 to rotate and drive the food in the wok 40 to stir-fry, so that the microwave energy is evenly distributed on the food, and the food is evenly heated.

[0030] When the wok 40 leaves the pot cover 50 for other cooking actions (the feeding device puts food into the wok 40 or the food is served after cooking), the main control circuit controls the microwave generator 1 to stop working to prevent microwave leakage. The specific control method is as follows:

[0031] Firstly, a control module is provided in the control circuit for disconnecting the working power supply of the magnetron in the microwave generator 1 when a cover opening signal is sent to the pot cover 50 or the frying pan 40 .

[0032] Secondly, a touch switch (not shown in the figure) is provided between the pot cover 50 and the pot mouth, which is used to cut off the power supply of the control circuit of the microwave generator 1 when the pot cover 50 leaves the pot mouth.

[0033] In this way, the double safety control mode ensures that the microwave generator 1 is in the off state when the pot cover 50 is opened, thereby ensuring safety during the cooking process.

[0034] Furthermore, in order to prevent microwaves from leaking from the joint between the pot cover 50 and the pot mouth, a sealing structure 54 is provided in the circumferential direction of the pot cover body 53 to prevent microwave leakage. The sealing structure 54 preferably has the following structures:

[0035] 1. The sealing structure comprises a metal mesh having an annular structure with two edges connected to form a V-shaped cross-section. The metal mesh is circumferentially attached to the lid body 53 with its V-shaped opening facing the central axis of the lid body 53. When the lid body 53 is closed over the wok 40, one edge of the metal mesh presses against the rim of the wok 40 and elastically deforms under the pressure of the wok 40 to fit tightly against the rim of the wok 40 (the mesh aperture of the metal mesh satisfies the requirement for preventing microwave leakage).

[0036] 2. The sealing structure is a sealing ring with a coating that reflects microwaves.

[0037] 3. The sealing structure is to set a mesh grid inside the sealing ring, and the mesh grid is made of metal.

[0038] When the pot cover body 53 is closed on the pot mouth of the wok 40, the metal mesh or sealing ring is elastically pressed against the pot mouth; when the wok 40 rotates, the wok 40 drives the pot cover body 53 to rotate synchronously through friction resistance, so that during the cooking process of the wok 40 rotating, the pot cover body 53 is always sealed on the pot mouth of the wok 40 through the sealing structure 54, preventing the microwaves in the wok 40 from leaking from the pot cover 50 and the pot mouth of the wok 40.

[0039] Openings communicating with each other are provided on the upper fixing plate 51 and the lower fixing plate 52 . One end of the smoke exhaust pipe 91 is connected to the opening, and the other end is connected to the oil fume inlet of the oil fume treatment device 80 .

[0040] An isolation structure is provided in the exhaust pipe 91 to prevent microwaves from leaking outwards with the wind. The isolation structure is a metal grid (the aperture of the metal grid meets the requirement of preventing microwave leakage).

[0041] Furthermore, a fork (not shown in the figure) is provided in the wok 40 for flipping the ingredients up and down and rotating relative to the wok 40. The fork can be made of food-grade non-metallic material or a metal material with a smooth surface. During the cooking process, the fork is always covered by the ingredients to avoid the accumulation of a large amount of charge under the action of microwaves and the generation of electric sparks.

[0042] The present invention provides a fork in the frying pan 40 to stir-fry the food, so that the food is stir-fried more evenly, and the heating effect of microwave heating is further improved.

[0043] A microwave leakage detection device is provided near the outside of the pot cover 50 and at any position in the exhaust pipe 91 behind the isolation structure. The microwave leakage detection device is electrically connected to the microwave radiation alarm device of the control circuit. Modes for Carrying Out the Invention
