Referring to fig. 1-3, a cooking apparatus 100 according to an embodiment of the present invention includes a housing 110, a cooking assembly 120, and a microwave assembly 130. The cooking assembly 120 includes a cooking table 121 and a cooking cover 122. The cooking table 121 is disposed on a surface of the housing 110. The cooking cover 122 is movably coupled to the housing 110 for covering the cooking table 121 and forming a closed space 123. The microwave assembly 130 includes a microwave generating device 131 and a wave adjusting device 132. The microwave generating device 131 is used for generating microwaves. The wave adjusting device 132 is used for adjusting microwaves to form a microwave field covering the preset cooking space 118 at the cooking table 121. The magnitude of the energy intensity of the microwave field outside the preset cooking volume 118 is close to zero.

Specifically, in the illustrated embodiment, the microwave assembly 130 generates microwaves through a microwave generating device 131. The microwaves are conducted to the wave adjusting device 132, so that the wave adjusting device 132 adjusts the microwaves, and the adjusted microwaves are output from the wave adjusting device 132 and have a propagation characteristic that the magnitude of energy intensity is reduced along with the increase of the propagation distance. In the case where the adjusted microwaves are conducted to the cooking table 121, the adjusted microwaves continue to propagate outward from the location of the cooking table 121, have energy intensities that are attenuated by the above-mentioned propagation characteristics, and are close to zero after reaching a certain distance, so that a propagation region having a certain energy intensity is formed around the cooking table 121, and the energy intensity of the adjusted microwaves located outside the propagation region is close to zero.

Under the condition that an object (such as food) to be heated is placed in the propagation area, as the object is in an electromagnetic field area with high frequency change formed by the regulated microwaves, molecules in the object move at a high speed along with the electromagnetic field with high frequency change, and the molecules can increase the internal energy of the molecules to generate heat during the movement, so that the whole object is heated, and the cooking effect is realized. In one embodiment, the propagation characteristics of the microwave after adjustment are such 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 microwaves propagate at the cooking table 121 in a direction away from the wave-tuning device 132 to form a microwave field. The energy intensity of the microwave field is gradually attenuated in the direction of the cooking table 121 away from the wave adjusting device 132, and a preset cooking space 118 is formed in a space within a first distance range. On the premise that the microwave field forms a propagation area with a certain range, when the cooking apparatus 100 heats food located in the propagation area, the adjusted microwaves cover the entire propagation area to form a preset cooking space 118 for the food, and the energy intensity of the adjusted microwaves when located outside the preset cooking space 118 is quite small, so that potential safety hazards such as radiation to a human body, heating and fire of surrounding dry objects and the like are difficult to form.

Moreover, since the adjusted microwaves can be cooked in the preset cooking space 118, and the region formed by the preset cooking space 118 is limited by the propagation characteristics, the cooking table 121 can be arranged on the open surface outside the cooking apparatus 100, and the corresponding closed structure is not required to be arranged at the position of the cooking table 121 so that the microwaves can resonate and prevent the microwaves from leaking, and a user can view the cooking condition of the food in real time. The cooking cover 122 can cover the cooking table 121 movably, so that liquid can be prevented from splashing outside a preset cooking space when food is boiled at a high temperature during cooking, and a user cannot touch the cooking table 121 by mistake and be scalded. In one embodiment, the maximum distance value of the first distance range is in the range of (2, 4) cm.

In the above cooking apparatus, the microwave is adjusted by the wave adjusting device 132, so that a microwave field with a certain coverage area is formed in the closed space 123 at the cooking table 121, the microwave field in the coverage area has a larger energy intensity, so that the cooking apparatus can be used for cooking, and the cooking cover 122 can cover the cooking table 121 in an area outside the coverage area, thereby avoiding liquid from splashing outwards during cooking and a user from touching the area in the coverage area by mistake, and improving the safety.

In addition, in the embodiment shown in fig. 2, the cooking apparatus 100 further includes an electric control part 124. The electric control part 124 is electrically connected to the microwave generating device 131, so as to control the microwave generating device 131 to generate microwaves. The electronic control 124 may also be used to regulate the operating voltage and power of the electrical components of the cooking device 100. The cooking apparatus 100 may further include a heat radiating part 112 for radiating heat.

In addition, for convenience of understanding, the following embodiments are described with reference to application scenarios in which the cooking apparatus 100 is a microwave oven, and it is to be understood that, based on embodiments of the present invention, the technical solution of the present invention may also be applied to other types of cooking apparatuses (e.g., induction cookers, ovens), so as to achieve the same or similar technical effects, which will be apparent to those skilled in the art. Therefore, on the premise that the embodiments of the present invention do not make explicit excluding claims to identify the cooking apparatus to which the embodiments of the present invention are not applied, other types of cooking apparatuses should fall within the protection scope of the present invention, and detailed descriptions of the embodiments of the other types of cooking apparatuses are omitted herein.

Referring to fig. 1,2 and 4, in some embodiments, the housing 110 includes a rotating base 111. Cooking cover 122 includes movable member 112. The movable member 112 is rotatably coupled to the rotation base 111 and forms a rotation shaft such that the cooking cover 122 is rotatably movably coupled to the housing 110 along the rotation shaft. In this way, the cooking cover 122 can be closed on the housing 110 with the cooking table 121 turned upside down.

Specifically, in the embodiment of fig. 1,2 and4, the number of the rotation bases 111 is two, and the two rotation bases 111 are provided on both sides of the housing 110, respectively. The number of the movable members 112 is two, and the two movable members 112 are respectively disposed at both sides of the cooking cover 122. When the cooking cover 122 is movably coupled to the housing 110, the cooking cover 122 is movably coupled to one of the rotation bases 111 by one of the moving members 112 and is movably coupled to the other of the rotation bases 111 by the other of the moving members 112 such that the two moving members 112 respectively located at both sides of the cooking cover 122 can simultaneously move the entire cooking cover 122 in the same direction with respect to the respective coupled rotation bases 111, thereby allowing the two moving members 112 to form a rotation axis L along which the cooking cover 122 can rotate with respect to the housing 110, thereby being capable of reversibly closing the cooking table 121 to form a closed space 123.

It will be appreciated that although the range over which the conditioned microwaves can propagate around the cooking table 121 is limited, there may be situations where the food to be cooked is boiled and there is a higher temperature around the cooking table 121, etc. When food is boiled, liquid (water and oil) may splash around, and when the temperature around the cooking table 121 is high, the user may touch by mistake and get scalded. In the above case, the cooking base 121 is covered by the cooking cover 122, so that liquid splashing, erroneous touch by a user, and the like can be avoided.

In addition, since the cooking cover 122 detachably covers the cooking table 121, it is unnecessary to cover the food before and after cooking, thereby facilitating the taking of the food. When the housing 110 is stored, the housing is small in size because the housing does not have the closed space, so that the storage space can be conveniently saved. The housing 110 and the cooking cover 122 may be separated at the time of cleaning, thereby facilitating cleaning of the cooking cover 122 and the housing 110 and convenient operation.

With reference to fig. 1 again, in some embodiments, cooking lid 122 includes receiving surface 113 and lid rim 114. Specifically, referring to fig. 4, in the embodiment shown in fig. 1 and 4, the cooking cover 122 is in a semi-closed configuration with a cover rim 114 formed at the rim. The plane formed by the receiving surface 113 and the plane formed by the cover rim 114 are perpendicular to each other.

When the cooking cover 122 rotates, the cooking cover can be in a state of opening the cooking table 121 by mutually attaching the bearing surface 113 and the surface of the shell 110, or in a state of closing the cooking table 121 by mutually attaching the cover edge 114 and the surface of the shell 110, the cooking cover 122 can be stably placed on the surface of the shell 110 by the bearing surface 113 and the cover edge 114, and the plane formed by the bearing surface 113 and the plane formed by the cover edge 114 are mutually perpendicular, so that the angle required by the state switching of the cooking cover 122 between the opening and the closing of the cooking table 121 is also larger, the opening and the closing of the cooking cover 122 are facilitated, and a user can clearly distinguish whether the cooking cover 122 is closed on the cooking table 121 or not, so that the fool-proof effect is better.

Referring to fig. 2 and 3, in some embodiments, the housing 110 includes an opening 115. A cooking table 121 is provided at the opening 115. The microwave assembly 130 is housed within the housing 110. In this manner, cleaning of the cooking apparatus 100 may be facilitated.

Specifically, in the embodiment shown in fig. 3, the housing 110 is internally formed with a receiving space 116, and the opening 115 is located on the surface outside the housing 110 and communicates with the receiving space 116. The cooking table 121 closes the opening 115 along the plate-like plane thereof, so that the microwave assembly 130 in the receiving space 116 is enclosed in the receiving space 116.

It will be appreciated that, for the cooking apparatus 100, since there is no need to provide a closed structure for the location of the cooking table 121, in the case where the opening 115 is located on the surface outside the housing 110, the cooking table 121 is correspondingly exposed on the surface outside the housing 110, so that the cleaning of the surface outside the housing 110 and the cooking table 121 by the user is facilitated, and no dead space difficult to clean is generated due to the closed structure.

Referring to fig. 2-5, in some embodiments, the tuning device 132 is accommodated in the housing 110. The wave-regulating device 132 includes a wave-guiding channel 133 and an energy-gathering cavity 136. Both ends of the waveguide 133 are connected to the energy collecting cavity 136 and the microwave generating device 131, respectively. The waveguide 133 is used to guide microwaves generated by the microwave generating device 131 into the energy concentrating cavity 136. The energy concentrating cavity 136 includes a wave modulating structure 137 and a converging port 138. The wave adjusting structure 137 is used for adjusting the energy intensity of the microwave to be within a preset intensity range. The converging port 138 communicates with the opening 115. The converging port 138 is used for converging microwaves with energy intensity within a preset intensity range toward the direction where the opening 115 is located. Thus, the microwave can be adjusted advantageously.

Specifically, in the embodiment shown in fig. 5, the waveguide channel 133 has a first waveguide end 134 and a second waveguide end 135. The first waveguide 134 communicates with the microwave generator 131, and the second waveguide 135 communicates with the energy collecting cavity 136. The second waveguide 135 has a flared shape, so that the waveguide 133 has a flared structure as a whole. The microwave generating device 131 generates microwaves at the first waveguide end 134 of the waveguide 133, and the microwaves are conducted from the first waveguide end 134 to the second waveguide end 135. The second waveguide 135 is horn-shaped, so that the microwave is finally conducted along the horn-shaped direction, and the second waveguide 135 has the function of guiding the microwave in the conducting direction.

In the case that microwaves are conducted into the energy collecting cavity 136, the wave adjusting structure 137 can adjust the microwaves located in the energy collecting cavity 136, so that the energy intensity corresponding to the adjusted microwaves is within a preset intensity range, and the microwaves are converged at the position along the converging opening 138 to be conducted to the position where the opening 115 is located, so as to cover the preset cooking space 118 formed around the cooking table 121.

In one embodiment, the preset intensity range has a maximum intensity value such that the intensity of the energy of the adjusted microwaves finally conducted to the cooking table 121 is not greater than the maximum intensity value, and such that the preset cooking space 118 does not occupy an excessive space. In another embodiment, the preset intensity range has a minimum intensity value such that the energy intensity of the adjusted microwaves finally conducted to the cooking table 121 is not less than the maximum intensity value, and such that the energy intensity of the adjusted microwaves is not attenuated too rapidly. In other embodiments, the microwave generating device 131 is a magnetron.

Referring to fig. 5, in some embodiments, the wave-tuning structure 137 includes a plurality of wave-tuning plates 1371. The plurality of waveplates 1371 are arranged in a plurality of rows at a first interval. The plurality of waveplates 1371 in each row are sequentially spaced apart at a second interval. The length direction of the waveplates 1371 is parallel to the row direction in which the plurality of waveplates 1371 are arranged. The guiding direction of the microwave by the waveguide 133 is parallel to the alignment direction of the plurality of waveplates 1371. Thus, the microwave adjusting function can be realized.

Specifically, in the embodiment shown in fig. 5, a plurality of wave plates 1371 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 pitch of the waveplate 1371 is formed in the first direction at a first pitch. The pitch of the waveplate 1371 is formed at a second pitch along the second direction. The converging port 138 is located above the plurality of waveplates 1371.

The wave plate 1371 is integrally formed in a plate-like structure and forms a plane of the wave plate 1371, and the wave plate 1371 has a length along a direction along which the plane thereof extends. The length direction of the waveplate 1371 is parallel to the first direction. When microwaves are guided into the energy collection cavity 136, the direction in which the wave guide channel 133 guides the microwaves is perpendicular to the plane of the wave plate 1371 and parallel to the second direction.

In the case that microwaves are directed to the energy collection chamber 136, the microwaves may be conducted through any one of the columns of the array in a direction perpendicular to the plane of the wave plates 1371, so that the energy intensity of the microwaves is changed between the columns of the wave plates 1371, and when the microwaves are adjusted such that the energy intensity is within a preset intensity range, the microwaves may be collected at the collection port 138 and reach the location of the cooking table 121.

Regarding the energy intensity of the microwaves after being adjusted, the corresponding adjustment may be made by changing at least one of the number of the wave plates 1371 in each column, the number of the wave plates 1371 in each row, the first interval, and the second interval.

Referring to fig. 6 and 7, in some embodiments, cooking cover 122 includes an electric drive 161. The electric driving part 161 is provided at one side of the cooking cover 122 toward the cover setting direction. In this way, cooking can be performed by the electric driving part 161 on the cooking cover 122 and the wave adjusting device 132.

Specifically, in the embodiment shown in fig. 6 and 7, the unitary semi-enclosed structure of cooking lid 122 forms a lid rim 114 at the edge of cooking lid 122. When the cooking cover 122 is rotated, the cover rim 114 contacts the surface of the housing 110, thereby covering the cooking table 121, and the cover direction is oriented toward the cooking table 121. The electric drive portion 161 is provided inside the semi-closed structure. In the case that the cooking cover 122 covers the cooking table 121, the electric driving part provided on the cooking cover 122 can be connected to the corresponding power supply circuit, so that the cooking apparatus 100 can supply power to the electric driving part 161, and the electric driving part is also located in the closed space 123, so that the electric driving part 161 and the wave adjusting device 132 can perform matched cooking.

In addition, in the embodiment shown in fig. 6, the electric driving part 161 includes an electric heating element 162. The electric heating member 162 may heat the food above the cooking table 121. In the embodiment shown in fig. 7, the electric driving part 161 includes a hot air piece 163. The hot air part 163 may form convection hot air around the cooking table 121. It will be appreciated that by providing the electric drive 161 and/or the hot air member 163, the temperature increase around the cooking table 121 may be increased, so that the food may be cooked in cooperation with the adjusted microwaves generated by the wave adjusting device 132.

Referring to fig. 6 and 7, in some embodiments, the electric driving part is maintained in a power-off state in a state where the cooking cover 122 is not covered with the cooking table 121. In this way, safety can be ensured during cooking.

Specifically, in the embodiment shown in fig. 6 and 7, when the cooking cover 122 covers the cooking table 121, the cooking apparatus may communicate with the electric driving part to supply power to the electric driving part, and when the cooking cover 122 does not cover the cooking table 121, the cooking apparatus may disconnect power supply to the electric driving part.

It can be understood that the cooking cover 122 does not cover the cooking table 121, meaning that the cooking device does not need to cooperate with the electric driving part to cook at this time, and further does not need to supply power to the electric driving part, so that the power-off state of the electric driving part is maintained, and the electric driving part is not opened by mistake to cause potential safety hazards such as temperature loss and electric leakage, so as to ensure the safety during cooking.

In some embodiments, whether the cooking cover 122 covers the cooking table 121 may be determined by determining a rotation angle of the cooking cover 122. Specifically, in one embodiment, a state in which the cooking cover 122 completely covers the cooking table 121 may be set as 0 degrees, the cooking cover 122 may form an angle with respect to 0 degrees when rotated, and when the formed angle is greater than or equal to a predetermined angle, the cooking cover 122 may be considered to be in a state in which the cooking table 121 is not covered, so that a power-off state of the electric driving part may be maintained. Cooking cover 122 fully covers cooking table 121 and may be configured such that cooking cover 122 fully conforms to housing 110 along cover rim 114.

Referring to fig. 8 and 9, in some embodiments, the cooking apparatus 100 includes a wave absorbing portion 170. The wave absorbing part 170 is disposed around the cooking table 121. The wave absorbing portion 170 includes 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 adjusting device 132. The wave absorbing part 170 serves to absorb energy of microwaves located at the cooking table 121. The heat absorbing body 171 is used to convert the energy absorbed by the wave absorbing portion 170 into heat energy. Thus, the multifunctional cooking device can be beneficial to realizing the function of cooking foods in various ways.

Specifically, in the embodiment shown in fig. 8 and 9, the wave absorbing portion 170 is disposed around the cooking table 121 along the cooking table 121, so that leakage of microwaves from a gap between the housing 110 and the cooking table 121 can be prevented. When the microwaves propagate to the position of the cooking table 121, the microwave absorbing layer 172 is disposed towards the wave adjusting device 132, so that the microwave absorbing layer 172 absorbs part of the microwaves to generate heat, and the heat absorbing body 171 absorbs the heat generated by the microwave absorbing layer 172, thereby forming a high temperature environment around the cooking table 121, and further cooking food in cooperation with the microwaves.

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, so that it may have a good temperature resistant 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 portion 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.

On the basis of the foregoing embodiment, 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 patterns may be achieved by any combination of different components.
