Referring to fig. 1 to 3, a cooking apparatus 100 according to an embodiment of the present invention includes a cooking table 110 and a microwave assembly 120. The microwave assembly 120 includes a microwave generating device 130 and a wave modulating device 140. The microwave generating device 130 is used to generate microwaves. The wave adjusting device 140 is used to adjust the microwaves to form a microwave field covering the preset cooking space 113 at the cooking table 110. The magnitude of the energy intensity of the microwave field outside the preset cooking space 113 is close to zero.

Specifically, in the illustrated embodiment, the microwave assembly 120 generates microwaves via a microwave generating device 130. The microwaves are conducted to the wave modulation device 140, so that the wave modulation device 140 modulates the microwaves, and the modulated microwaves are output from the wave modulation device 140 and have a propagation characteristic that the energy intensity decreases with the increase of the propagation distance. In the case that the adjusted microwave is conducted to the cooking table 110, the adjusted microwave will continue to propagate outwards from the position of the cooking table 110, and the energy intensity will be attenuated by the propagation characteristics and will approach zero after reaching a certain distance, so that a propagation area with a certain energy intensity is formed around the cooking table 110, and the energy intensity of the adjusted microwave outside the propagation area will approach zero.

On the basis, under the condition that an article (such as food) to be heated is placed in the propagation area, molecules in the article move at a high speed along with a high-frequency changing electromagnetic field due to the fact that the article is located in the high-frequency changing electromagnetic field formed by the adjusted microwave, the internal energy of the molecules can be increased during movement to generate heat, and then the whole article is heated, and the cooking effect is achieved. In one embodiment, the propagation characteristic of the adjusted microwave is that the magnitude of the energy intensity decreases exponentially with increasing propagation distance.

On the basis of the above, please refer to fig. 3, the adjusted microwave propagates in the cooking platform 110 in a direction away from the wave modulating device 140 to form a microwave field. The energy intensity of the microwave field is gradually attenuated in the cooking table 110 in a direction away from the wave modulating device 140, and a predetermined cooking space 113 is formed in a space within the first distance range. On the premise that the microwave field forms a propagation region having a certain range, when the cooking apparatus 100 heats food located in the propagation region, the adjusted microwave covers the entire propagation region to form the preset cooking space 113 for the food, and the energy intensity of the adjusted microwave located outside the preset cooking space 113 is relatively small, so that it is difficult to form safety hazards such as radiation to the human body, fire due to heating of surrounding dry objects, and the like.

Moreover, since the adjusted microwave is cooked in the preset cooking space 113, and the area formed by the preset cooking space 113 is limited by the propagation characteristics, the cooking table 110 can be disposed on the open surface outside the cooking apparatus 100, and a corresponding closed structure is not required to be disposed at the position of the cooking table 110 to enable the microwave to resonate and prevent the microwave from leaking, so that the user can check the cooking condition of the food in real time. In one embodiment, the maximum distance value of the first distance range is (2,4) centimeters.

In the cooking apparatus 100, the microwave is adjusted by the wave adjusting device 140, so that a microwave field with a certain coverage area can be formed at the cooking platform 110 after the microwave is adjusted, the microwave field in the coverage area has a larger energy intensity, and thus the microwave field can be used for cooking, and the energy intensity of the microwave field outside the coverage area is close to zero, so that the potential safety hazard is not easily formed, and a closed space is not required to be arranged for cooking by using the microwave.

In addition, in the embodiment shown in fig. 2, the cooking apparatus 100 further includes an electric control part 111. The electric control unit 111 is electrically connected to the microwave generating device 130, and thus can be used to control the microwave generating device 130 to generate microwaves. The electric control part 111 may also be used to adjust the operating voltage and power of the electric components of the cooking apparatus 100. The cooking apparatus 100 may further include a heat dissipation part 112 for dissipating heat.

In addition, for convenience of understanding, the following embodiments are mostly described in an application scenario in which the cooking apparatus 100 is a microwave oven, and it is understood that, on the basis of the embodiments of the present invention, the technical solution of the present invention may also be applied to other types of cooking apparatuses (such as an induction cooker and an oven), so that the same or similar technical effects can be achieved, which is easily conceivable for those skilled in the art. Therefore, on the premise that the embodiment of the present invention does not make explicit exclusions to identify the cooking apparatus to which the embodiment of the present invention is not applicable, other types of cooking apparatuses should fall within the scope of the present invention, and the detailed description of the embodiment of other types of cooking apparatuses is omitted here.

Referring to fig. 1, in some embodiments, the cooking apparatus 100 includes a housing 150. The housing 150 includes an opening 151. The cooking table 110 is disposed at the opening 151. The microwave assembly 120 is housed within a housing 150.

As such, cleaning of the cooking apparatus 100 may be facilitated.

Specifically, in the embodiment shown in fig. 3, a receiving space 152 is formed inside the housing 150, and the opening 151 is located on a surface outside the housing 150 and communicates with the receiving space 152. The cooking table 110 closes the opening 151 along a plate-shaped plane thereof such that the microwave assembly 120 in the receiving space 152 is enclosed in the receiving space 152.

It can be understood that, for the cooking apparatus 100, since there is no need to provide a closing structure for the position of the cooking bench 110, in the case that the opening 151 is located on the surface outside the housing 150, the cooking bench 110 is correspondingly exposed on the surface outside the housing 150, so that the user can conveniently clean the surface outside the housing 150 and the cooking bench 110, and no dead space which is difficult to clean is generated due to the closing structure.

Referring to fig. 2 and 4, in some embodiments, the wave tuning device 140 includes a wave guide channel 141 and a focusing cavity 144. The two ends of the wave guide channel 141 are respectively communicated with the energy collecting cavity 144 and the microwave generating device 130. The waveguide 141 guides the microwave generated by the microwave generating device 130 into the energy collecting cavity 144. The energy concentrating cavity 144 includes a wave modulating structure 145 and a concentrating port 146. The wave modulating structure 145 is used to modulate the energy intensity of the microwave to be within a predetermined intensity range. The convergence port 146 communicates with the opening 151. The convergence port 146 is used for converging the microwaves with energy intensity within a preset intensity range to the direction of the opening 151.

Thus, the microwave can be adjusted.

Specifically, in the embodiment shown in fig. 2 and 4, the wave guiding channel 141 has a first wave guiding end 142 and a second wave guiding end 143. The first wave guiding end 142 is connected to the microwave generating device 130, and the second wave guiding end 143 is connected to the energy collecting cavity 144. The second waveguide end 143 is flared such that the waveguide channel 141 is in a horn-shaped structure as a whole. The microwave generating device 130 generates microwaves at the first waveguide end 142 of the waveguide 141, and the microwaves are guided from the first waveguide end 142 to the second waveguide end 143. Since the second waveguide 143 is flared, the microwave is finally guided in a flared direction, and the second waveguide 143 guides the propagation direction of the microwave.

Under the condition that the microwaves are conducted into the energy collecting cavity 144, the wave modulating structure 145 can modulate the microwaves in the energy collecting cavity 144, so that the energy intensity corresponding to the modulated microwaves is within the preset intensity range, and the microwaves are converged along the converging port 146 to be continuously conducted to the position of the opening 151, thereby covering the preset cooking space 113 formed around the cooking platform 110.

In one embodiment, the preset intensity range has a maximum intensity value such that the intensity of the energy of the conditioned microwaves eventually conducted to the cooking station 110 is not greater than the maximum intensity value, and thus the preset cooking volume 113 does not occupy an excessive space. In another embodiment, the predetermined intensity range has a minimum intensity value such that the energy intensity of the conditioned microwaves eventually conducted to the cooking station 110 is not less than the maximum intensity value, and thus the energy intensity of the conditioned microwaves is not too rapidly attenuated.

In one embodiment, the microwave generating device 130 is a magnetron.

Referring to fig. 4, in some embodiments, the wave modulating structure 145 includes a plurality of wave modulating plates 147. The plurality of wave modulating plates 147 are arranged in a plurality of rows at the first interval. The plurality of tuning wave plates 147 in each row are sequentially spaced at a second spacing. The length direction of the wave modulating plate 147 is parallel to the row direction in which the plurality of wave modulating plates 147 are arranged. The guide direction of the microwave by the waveguide 141 is parallel to the alignment direction of the plurality of waveadjusting plates 147.

Thus, the microwave adjusting function can be realized.

Specifically, in the embodiment shown in fig. 4, the plurality of tuning wave plates 147 are arranged at intervals in the first direction and the second direction to form an array. The first direction is the row direction of the array. The second direction is the column direction of the array. The interval formed by the wave tuning plates 147 in the first direction is a first interval. The interval formed by the wave-adjusting plates 147 in the second direction is a second interval. The convergence port 146 is located above the plurality of tuning wave plates 147.

The wave modulating plate 147 has a plate-like structure as a whole and forms a plane of the wave modulating plate 147, and the wave modulating plate 147 has a length along a direction in which the plane extends. The length direction of the wave tuning plate 147 is parallel to the first direction. When the microwaves are guided into the energy concentrating cavity 144, the direction in which the microwaves are guided by the waveguide 141 is perpendicular to the plane of the wave tuning plate 147 and parallel to the second direction.

With the microwaves directed to the energy concentrating chamber 144, the microwaves may be conducted through any one of the columns of the array in a direction perpendicular to the plane of the wave modulating plate 147 such that the energy intensity of the microwaves is varied between the columns of the wave modulating plate 147, and the microwaves may be concentrated at the concentration port 146 and reach the location of the cooking stage 110 when the microwaves are adjusted to have an energy intensity within a predetermined intensity range.

With respect to the energy intensity of the microwave after being modulated, it is possible to adjust accordingly by changing at least one of the number of the wave modulating plates 147 in each column, the number of the wave modulating plates 147 in each row, the first interval, and the second interval.

Referring to fig. 5, in some embodiments, the cooking apparatus 100 includes a housing 150 and a cover 160. The housing 150 includes an opening 151. The cooking table 110 is disposed at the opening 151. The cover 160 is detachably attached to the housing 150 via the cover rim 167 to cover the cooking table 110.

Thus, the splashing of the liquid and the user's erroneous touch to the cooking table 110 can be prevented.

Specifically, in the embodiment shown in fig. 5, the surface of the housing 150 on which the cooking stage 110 is provided is entirely planar. The cover 160 is a semi-enclosed structure with a cover rim 167 formed at the edge. When the cooking stage 110 is covered, the cover 160 covers the cooking stage 110 located at the opening 151 of the casing 150 by contacting and adhering the covering edge 167 to the surface of the casing 150.

It will be appreciated that although the range over which the conditioned microwaves can propagate around the cooking table 110 is limited, there may be conditions in which the food to be cooked is boiled and there is a higher temperature around the cooking table 110. When the food is boiling, it may cause the liquid (water, oil) to splash around, and when the temperature around the cooking table 110 is high, it may cause the user to be burned by touching it by mistake. In this case, the lid 160 covers the cooking table 110, so that the splashing of the liquid and the erroneous touch of the user can be avoided. Moreover, since the cover 160 is detachably installed to cover the cooking table 110, it is not necessary to cover the food before and after cooking, which facilitates the taking and putting of the food. When the housing 150 is stored, since it does not have the aforementioned closed space and has a small size, the storage space can be conveniently saved. The case 150 and the cover 160 can be separated during cleaning, so that the cover 160 and the case 150 can be cleaned conveniently, and the operation is convenient.

Referring to fig. 6 and 7, in some embodiments, cover 160 includes an electric drive 161 and a first electric connection port 166. The electric drive section 161 is electrically connected to the first electric connection port 166. The electric drive unit 161 is provided on the side of the cover 160 facing the covering direction. The first electrical connection port 166 is provided at the capping rim 167. The housing 150 includes a second electrical connection port 153. When the cover 160 is attached to the case 150 along the edge, the second electrical connection port 153 is electrically connected to the first electrical connection port 166 to supply power to the electric driver 161.

In this way, the cooking can be performed by the electric driving part 161 of the cover 160 and the wave modulation device 140.

Specifically, in the embodiment shown in fig. 6 and 7, the semi-closed structure of the entirety of the cover body 160 forms the covering direction of the cover body 160. The electric driving part 161 is disposed inside the semi-closed structure. In the case that the cover body 160 covers the cooking table 110, the first electrical connection port 166 provided at the covering edge 167 and the second electrical connection port 153 provided at the housing 150 are connected to each other to form electrical communication, and the cooking apparatus 100 can supply power to the electric driving part 161 provided at the cover body 160 through the second electrical connection port 153, so that the electric driving part 161 and the wave modulation device 140 can perform coordinated cooking.

In one embodiment, the first electrical connector 166 is disposed at the edge of the cover 160, and the second electrical connector 153 is disposed at the surface of the housing 150, such that the first electrical connector 166 is inserted into the second electrical connector 153 to form electrical communication. In other embodiments, the first electrical connection port 166 may be recessed in the edge of the cover 160 and the second electrical connection port 153 may be raised in the surface of the housing 150.

In addition, in the embodiment shown in fig. 6, the electric driving part 161 includes an electric heating member 162. The electric heating member 162 may heat food above the cooking table 110. In the embodiment shown in fig. 7, the electric drive 161 includes a hot air blast 163. The hot wind member 163 may form hot wind in convection around the cooking table 110. It can be understood that the electric driving part 161 and/or the hot wind member 163 may be provided to accelerate the temperature rise around the cooking platform 110, so that the food may be cooked in cooperation with the adjusted microwave generated by the wave adjusting device 140.

Referring to fig. 8 and 9, in some embodiments, the cooking apparatus 100 includes a wave-absorbing part 170. The absorbent part 170 is circumferentially disposed along the edge of the opening 151. The wave-absorbing part 170 comprises a heat-absorbing body 171 and a wave-absorbing layer 172. The wave absorbing layer 172 is disposed on a side of the heat absorbing body 171 facing the wave tuning device 140. The absorbent part 170 serves to absorb energy of the microwaves at the opening 151. The heat absorbing body 171 serves to convert the energy absorbed by the wave absorbing part 170 into thermal energy.

Thus, the food cooking device can be beneficial to realizing the function of diversified cooking of food.

Specifically, in the embodiment shown in fig. 8 and 9, the microwave absorbing part 170 is disposed around the cooking table 110 along the edge of the opening 151, so that the microwave can be prevented from leaking out from the gap between the opening 151 and the cooking table 110. Under the condition that microwave propagates to the position of opening 151, because wave-absorbing layer 172 sets up towards wave modulation device 140 to can make wave-absorbing layer 172 absorb partial microwave and generate heat, heat absorption body 171 then can absorb the produced heat of wave-absorbing layer 172, thereby form high temperature environment around cooking platform 110, and then can cooperate the microwave to cook food.

In addition, in some embodiments, the material of the heat absorbing body 171 is metal, so that the heat absorbing speed of the heat absorbing body 171 may be increased. The material of the heat absorbing body 171 may also be ceramic, and thus may have a good temperature resistance effect. In other embodiments, the heat absorbing body 171 may be made of metal or ceramic.

In other embodiments, the material of the wave-absorbing part 170 may be an iron-based wave-absorbing material, a silicon carbide-based wave-absorbing material, or an iron-based wave-absorbing material or a silicon carbide-based wave-absorbing material.

In addition to the foregoing embodiments, referring to fig. 10, in the illustrated embodiment, the electric driving part 161 includes an electric heating element 162 and a hot air element 163. It will be appreciated that different types of cooking may be achieved by any combination of the different components. Specifically, in some embodiments, the cooking apparatus 100 may individually cook food in the preset cooking space 113 by microwave, so that heating of milk, coffee, thawing of food, turning over of meal, and the like may be achieved; the cooking apparatus 100 may perform combined cooking of food by the hot wind member 163 in combination with microwaves, thereby achieving air frying effects such as french fries, fried chicken rice, fried chicken wings, roasted sweet potatoes, roasted chicken, and the like; the cooking apparatus 100 may perform combined cooking on food by combining the microwave absorbing part 170 with microwave, thereby implementing a frying, stir-frying, and deep-frying cooking manner. In other embodiments, the cooking apparatus 100 may perform separate cooking of food through the hot wind member 163, thereby implementing an air fryer cooking mode; the cooking apparatus 100 may perform combined cooking on food by combining the hot wind member 163 with the wave-absorbing part 170, so that a cooking effect of frying up and baking down, such as frying steak, may be realized.
