Description

Technical Field

[0001] The 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] The existing intelligent cooking machine is composed of a frame, a sealed cavity, a wok assembly and a feeding device. The dishes cooked by this type of intelligent cooking machine according to the set program can be comparable to the small stir-fried dishes cooked by chefs, but it still has 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 ingredients may be cooked on the outside but raw on the inside; if the cooking time is too long, the ingredients may be cooked on the inside but burnt on the outside. Summary of the invention

[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 internal and external doneness of cooking ingredients.

[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, wherein the wok assembly is composed of a wok, a furnace core for heating the wok, and a pot cover that can cover the mouth of the wok. When the wok containing ingredients rotates and is sealed with the pot cover above it, at least one group of microwave generators installed on the pot cover feeds microwaves to the ingredients in the pot.

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

[0009] Preferably, a smoke exhaust pipe is provided on the pot cover to exhaust the oil smoke generated in the wok to the oil smoke treatment device, and an isolation structure is provided in the smoke exhaust pipe to prevent microwaves from leaking outward with 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, a control module is further provided in the control circuit for disconnecting the working power supply of the magnetron in the microwave generator when a cover-opening signal is sent to the pot cover or the frying pan.

[0013] Preferably, a touch switch is provided between the pot cover and the pot mouth for cutting off power to a control circuit for controlling 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.

[0015] In the prior art, the cooking machine has a relatively single heating method, usually using conduction heating or electromagnetic coil heating. The single heating method easily causes the cooking time to be too long and the cooking quality to be low. The present invention adds a microwave heating component on the basis of electromagnetic heating as the main heating method, and installs the microwave heating component on the pot cover that does not need to be removed in daily life. The microwave generated by the microwave heating component is directly or through at least one waveguide fed into the food in the stir-frying state and rotating with the pot. The advantage of this structure is that the cooked food can be heated evenly inside and outside, the cooking time is greatly shortened, and the cooked dishes are fragrant on the outside and tender on the inside.

DETAILED DESCRIPTION

[0020] like Figure 1 As described above, the intelligent cooking machine of the present invention includes a casing 10, a sealed cavity 100 is also provided in the casing 10 (the sealed cavity 100 is enclosed by an inner casing 20 which is arranged in the casing 10 and has an opening on 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 is composed of a wok 40, a furnace core 30 for heating the wok 40, and a pot cover 50 that can cover the wok 40. The furnace core 30 is composed of an inner cover, a heating assembly, and an outer cover. Preferably, the upper end of the inner cover is open, the bottom of the inner cover is a plane, and the vertical cross-section of the inner cover is an arc shape, which is the same as the arc shape of the vertical cross-section of the lower half of the wok 40. The heating assembly is composed of an electromagnetic coil and a plurality of fixings. The electromagnetic coil surrounds the outer wall of the inner cover and is fixed to the inner cover through the fixings. The outer cover is a cylindrical structure with an upper end open. The wok 40 is accommodated in the inner cover and can rotate relative to the furnace core 30 around its central axis.

[0022] The pot cover 50 is arranged in the sealed cavity 100 and placed at the upper rear of the sealed cavity 100. The stove core 30 can make the pot mouth of the wok 40 move toward the pot cover 50 through the wok lifting device 70 and is installed 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, which is arranged in the sealed cavity 100 and located above the wok 40; the wok station control device 80 is used to fix the stove core 30 on the wok lifting device 70, and control the stove core 30 to flip so that the pot mouth of the wok 40 faces the corresponding station (such as the pot mouth faces the pot cover position, the pot mouth faces the feeding device 60 position, and the pot mouth faces the dish delivery 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 with 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 discharge it out of the sealed cavity 100 or discharge it 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 in the traditional single heating method. The following is a detailed description in conjunction with the specific implementation method.

[0025] like Figure 2-3As shown, the pot cover 50 is made of microwave isolation material, and includes a rotating disk assembly and a pot cover liner assembly, and the rotating disk assembly is coaxially arranged with the pot cover liner assembly. The rotating disk assembly is composed of an upper fixed disk 51 and a lower fixed disk 52, and the pot cover body 53 of the pot cover liner assembly can be rotated and clamped between the upper fixed disk 51 and the lower fixed disk 52. A through hole adapted to the upper fixed disk 51 is provided on the rear side of the inner shell 20, and 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 frame arranged on the outer wall of the rear side of the inner shell 20 to fix the entire pot cover 50 rotating assembly on 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 generator 1 feeds microwaves into the wok 40 through at least one waveguide 2. The microwave energy emitted by the microwave generator 1 enters from one end of the waveguide 2 and is then fed into the wok 40 from the other end that passes through the upper fixed plate 51 and the lower fixed plate 52. A waveguide cover 3 is also provided at the other end of the waveguide 2 for preventing water vapor, oil smoke, etc. from entering the waveguide 2 and then contaminating the microwave source during cooking. The waveguide cover 3 can be made of microwave-transmissive material and is 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 a waveguide channel on the upper fixed plate 51 and the lower fixed plate 52 .

[0028] When the wok 40 containing the food is rotated and 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, feeding microwaves into the rotating wok 40, and forming a closed cooking cavity by covering the wok 40 and the pot cover 50, 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 avoid microwave leakage. The specific control method is as follows:

[0031] Firstly, a control module is provided in the control circuit to disconnect 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 insurance control mode ensures that the microwave generator 1 is in the off state when the pot cover 50 is opened, so as to ensure the 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 microwaves from leaking. The sealing structure 54 preferably has the following structures:

[0035] 1. The sealing structure is a metal mesh, which is annular in structure and has a "V"-shaped cross-section formed by two sides. The metal mesh is fixed to the circumferential direction of the pot cover body 53 with its "V"-shaped opening facing the central axis of the pot cover body 53. When the pot cover body 53 is covered on the wok 40, one side of the metal mesh is pressed against the pot mouth of the wok 40 and can be elastically deformed under the pressure of the wok 40 to fit tightly on the pot mouth of the wok 40 (the mesh aperture of the metal mesh meets the requirement of preventing microwave leakage).

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

[0037] 3. The sealing structure is a mesh grid arranged 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 to prevent the microwaves in the wok 40 from leaking from the pot cover 50 and the pot mouth of the wok 40.

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

[0040] An isolation structure for preventing microwaves from leaking outward with the wind is provided in the smoke exhaust duct 91. The isolation structure is a metal grid (the aperture of the mesh holes 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 electric charge and the generation of electric sparks under the action of microwaves.

[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 smoke exhaust duct 91 behind the isolation structure. The microwave leakage detection device is electrically connected to the microwave radiation alarm device of the control circuit.
