DETAILED DESCRIPTION

Embodiments of the present disclosure will be described in detail below, and examples of the embodiments are shown in accompanying drawings. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.

A split-type microwave oven100according to embodiments of the present disclosure will be described below with reference toFIGS. 1 to 5.

As shown inFIGS. 1 to 5, the split-type microwave oven100according to embodiments of the present disclosure includes a first housing assembly105, a second housing assembly120, a microwave source component140, a microwave shielding and choking member150and a detection device (not shown).

Specifically, the second housing assembly120is detachably disposed on the first housing assembly105. For example, as shown inFIG. 1, the first housing assembly105may be placed on a supporting member300, the supporting member300may be a table top or an operating bench of a kitchen stove herein, and the second housing assembly120and the first housing assembly105are detachably disposed from each other. The first housing assembly105is provided with a first microwave shielding member110, the second housing assembly120is provided with a second microwave shielding member121, and the first microwave shielding member110is adapted to define a microwave-heating resonant cavity130together with the second microwave shielding member121. A heated object400(e.g. food, and so on) may be placed into the microwave-heating resonant cavity130to be heated. It may be understood that microwave cannot be transmitted outside the microwave-heating resonant cavity130by passing through the first microwave shielding member110and the second microwave shielding member121.

When there is a need for removing the heated object400from the microwave-heating resonant cavity130or putting the heated object400into the microwave-heating resonant cavity130, the second housing assembly120may be removed or placed away from the first housing assembly105; when the heated object400is to be heated, the second housing assembly120is placed on the first housing assembly105, such that the first microwave shielding member110and the second microwave shielding member121define the microwave-heating resonant cavity130together.

The microwave source component140is mounted to one of the first housing assembly105and the second housing assembly120. That is to say, the microwave source component140may be mounted to the first housing assembly105, or may be mounted to the second housing assembly120. The microwave source component140includes a control unit, a power source142, an electric power supply143and an electromagnetic waveguide144. The electromagnetic waveguide144is adapted to guide the microwave into the microwave-heating resonant cavity130, and the control unit, the electric power supply143and the electromagnetic waveguide144are connected to the power source142respectively. Thus, the electric power supply143may supply power to the power source142, and the control unit may control the power source142to start or stop. The power source142may be a magnetron power source or a semiconductor power source142.

When the second microwave shielding member121is fitted with the first microwave shielding member110to define the microwave-heating resonant cavity130and after the control unit controls the power source142to start, the microwave is transmitted into the microwave-heating resonant cavity130through a coaxial cable145and the electromagnetic waveguide144. Under action of the first microwave shielding member110and the second microwave shielding member121, the microwave cannot pass through the first microwave shielding member110and the second microwave shielding member121, but can only be propagated into the microwave-heating resonant cavity130defined by the first microwave shielding member110and the second microwave shielding member121, such that the food placed in the microwave-heating resonant cavity130may be heated.

When the second microwave shielding member121is fitted with the first microwave shielding member110, the second microwave shielding member121and the first microwave shielding member110define the microwave-heating resonant cavity130together, but there may be a gap between the second microwave shielding member121and the first microwave shielding member110. In order to prevent a microwave leakage at a junction of the second microwave shielding member121and the first microwave shielding member110, a microwave shielding and choking member150may be disposed outside the microwave-heating resonant cavity130. The microwave shielding and choking member150is located outside the microwave-heating resonant cavity130to prevent a microwave leakage from the microwave-heating resonant cavity130. When the microwave-heating resonant cavity130is defined, the microwave shielding and choking member150may be disposed at the junction of the first microwave shielding member121and the second microwave shielding member110. For example, as shown inFIGS. 1 to 5, the microwave shielding and choking member150is disposed at a lower end of the second microwave shielding member121. Thus, the split-type microwave oven100may have a reasonable structure.

In order to further improve the safety of the split-type microwave oven100, the split-type microwave oven100may include a detection device. The detection device may be used to detect whether the microwave leakage occurs at the microwave-heating resonant cavity130, and the detection device may be connected to the control unit. It may be understood that a detection result of the detection device may be transmitted to the control unit, and the control unit may send out a corresponding control instruction according to the detection result. That is, when the lower end of the second microwave shielding member121is fitted with the first microwave shielding member110and the detection device detects that the microwave leakage occurs at the microwave-heating resonant cavity130, the control unit turns off the power source142, and thus the split-type microwave oven100cannot heat the food placed in the microwave-heating resonant cavity130; when the lower end of the second microwave shielding member121is fitted with the first microwave shielding member110and the detection device detects that the microwave leakage does not occur at the microwave-heating resonant cavity130, the control unit starts the power source142, and thus the split-type microwave oven100may heat the food placed in the microwave-heating resonant cavity130.

With the split-type microwave oven100according to some embodiments of the present disclosure, by using the second housing assembly120detachable from the first housing assembly105, the second microwave shielding member121may be fitted with or detached from the first microwave shielding member110, such that the microwave-heating resonant cavity130for heating food may be defined when needed, and the second housing assembly120may be stored away when there is no need for the split-type microwave oven100to heat food, thus reducing the space occupation of the split-type microwave oven100, improving an utilization of kitchen space, and satisfying use requirements of a user.

According to some embodiments of the present disclosure, as shown inFIG. 2, the microwave source component140is mounted in the first housing assembly105, and the first housing assembly105is movably disposed on the supporting member300. Herein, the supporting member300may be a table top or an operating top of the kitchen stove. Certainly, an arrangement of the first housing assembly105is not limited to this. For example, the first housing assembly105may also be embedded in the supporting member300(as shown inFIG. 3). Thus, the arrangement of the first housing assembly105is diversified, and the user may dispose the first housing assembly105according to practical requirements, thereby improving the satisfaction of the user. Further, in order to improve entire aesthetics of the split-type microwave oven100, an upper surface of the first housing assembly105may be flush with an upper surface of the supporting member300.

According to some embodiments of the present disclosure, as shown inFIGS. 1 to 3, a portion of the first microwave shielding member110is recessed towards an interior of the first housing assembly105to define a groove111. As shown inFIGS. 1 to 3, the split-type microwave oven100further includes a carrying plate200. The carrying plate200is disposed at an opening of the groove111, and is fitted with a side wall of the groove111, so as to define an enclosed cavity112. A portion of the electromagnetic waveguide144extending out of a housing is located in the cavity112. The carrying plate200is located in the microwave-heating resonant cavity130to carry the heated object400(e.g. the food, and so on).

It should be noted that the heated object400may be placed on an upper surface of the carrying plate200, and the carrying plate200may be made of wave-transmitting materials, such that the microwave in the cavity112may be propagated into the microwave-heating resonant cavity130. It may be understood that, when the food needs to be heated, the second microwave shielding member121may be fitted with the first microwave shielding member110to define the microwave-heating resonant cavity130, the control unit starts the power source142to produce the microwave, and the microwave is transmitted into the cavity112through the electromagnetic waveguide144, then further into the microwave-heating resonant cavity130, so as to heat the food. When the split-type microwave oven100is not needed to be used, the second housing assembly120may be stored away to prevent the split-type microwave oven100from occupying the kitchen space, thus, not only satisfying the use requirement of the user, but also improving the utilization of the kitchen space.

In order to improve the appearance aesthetics of the first housing assembly105, as shown inFIGS. 1 to 3, the upper surface of the carrying plate200is flush with a remaining portion of an upper surface of the first microwave shielding member110. Herein, “a remaining portion of an upper surface of the first microwave shielding member110” refers to a portion of the upper surface of the first microwave shielding member110except the groove111. In order to evenly transmit the microwave into the microwave-heating resonant cavity130, an end of the electromagnetic waveguide144located in the cavity112may be provided with an antenna or a stirring blade, such that the heated object400may be evenly heated to ensure a heating effect of the split-type microwave oven100, and thus the use requirement of the user may be satisfied. According to an example of the present disclosure, the antenna or the stirring blade is rotatably disposed on the end of the electromagnetic waveguide144. Thus, the evenness of microwave propagation is further improved.

According to another embodiment of the present disclosure, as shown inFIGS. 4 and 5, the microwave source component140is mounted to the second housing assembly120, and the microwave source component140further includes a coaxial cable145. The coaxial cable145is retractably connected between the power source142and the electromagnetic waveguide144, and the second microwave shielding member121is disposed on an end of the coaxial cable145adjacent to the electromagnetic waveguide144. The second housing assembly120further includes a wave-transmitting material member122, and the wave-transmitting material member122is disposed on a lower surface of the second microwave shielding member121to define an accommodating cavity123together with the second microwave shielding member121. The electromagnetic waveguide144is located in the accommodating cavity123.

It should be noted that the first housing assembly105may be disposed on the table top or the operating bench of the kitchen stove, the second housing assembly120may be fixed to a closet500. The closet500is generally located at a high position, and the second housing assembly may be fitted with or detached from the first housing assembly105by the retractable coaxial cable145, such that the first microwave shielding member110may be fitted with or detached from the second microwave shielding member121.

For example, as shown inFIGS. 4 and 5, an upper end of the coaxial cable145is connected to the power source142of the microwave source component140, and a lower end of the coaxial cable145is connected to the electromagnetic waveguide144. The coaxial cable145is retractable in an up-and-down direction (i.e., the up-and-down direction shown inFIGS. 4 and 5), and the second microwave shielding member121is disposed on the lower end of the coaxial cable145and covers over the electromagnetic waveguide144. The lower end of the second microwave shielding member121is adapted to be fitted with the first microwave shielding member110to define the microwave-heating resonant cavity130.

It may be understood that when the coaxial cable145is stretched or retracted, the second microwave shielding member121may be driven to move in the up-and-down direction (i.e. the up-and-down direction as shown inFIGS. 4 and 5). When the coaxial cable145is stretched downward and drives the second microwave shielding member121to move downward, as shown inFIG. 5, the lower end of the second microwave shielding member121may be fitted with the first microwave shielding member110, and the second microwave shielding member121may define the microwave heating cavity together with the first microwave shielding member110. When the coaxial cable145is retracted upward and drives the second microwave shielding member121to move upward, as shown inFIG. 4, a cavity component may be stored away at a position adjacent to the microwave source component140. The microwave source component140may be disposed on a mounting wall such as the closet500, etc. That is to say, when the lower end of the second microwave shielding member is fitted with the first microwave shielding member110, the split-type microwave oven100may heat the food placed in the microwave-heating resonant cavity130; when the second microwave shielding member121is stored away at the position adjacent to the microwave source component140, the second microwave shielding member121may be stored away, thus improving the space utilization.

As shown inFIGS. 4 and 5, the second housing assembly120further includes a wave-transmitting material member122, the wave-transmitting material member122is disposed on the lower surface of the second microwave shielding member121to define an accommodating cavity123together with the second microwave shielding member121, and the electromagnetic waveguide144is located in the accommodating cavity123. A shape of the wave-transmitting material member122may be substantially similar to a shape of the second microwave shielding member121, and a lower end of the wave-transmitting material member122is connected to the lower end of the second microwave shielding member121, such that the cavity component may have a compact structure. The electromagnetic waveguide144may guide the microwave into the accommodating cavity123, the microwave may enter the microwave-heating resonant cavity130after passing through the wave-transmitting material member122, and then the food placed in the microwave-heating resonant cavity130may be heated. In addition, the wave-transmitting material member122may further evenly diffuse the microwave into the heating resonant cavity130, such that the heated object400may be evenly heated to ensure the heating effect of the split-type microwave oven100, and thus the use requirement of the user may be satisfied.

In order to make the structure of the split-type microwave oven100more compact, as shown inFIGS. 4 and 5, the first microwave shielding member110may be embedded in the supporting member300. Certainly, the connection form between the first microwave shielding member110and the supporting member300is not limited to this. For example, the first microwave shielding member110may also be disposed on a surface of the supporting member300, such that types of the split-type microwave oven100may be diversified, and thus the use requirements of different users may be satisfied.

In order to further improve the safety of the split-type microwave oven100and reduce the possibility of microwave leakage between the second microwave shielding member121and the first microwave shielding member110, the first microwave shielding member110may be provided with a first clip member (not shown), and the second microwave shielding member121may be provided with a second clip member (not shown) configured to be fitted with the first clip member. Thus, the first microwave shielding member110may be firmly connected to the second microwave shielding member121through the fitting of the first clip member and the second clip member, so as to avoid the microwave leakage between the first microwave shielding member110and the second microwave shielding member121.

According to some embodiments of the present disclosure, at least one of the first microwave shielding member110and the second microwave shielding member121is a metal member. Thus, a production cost may be saved.

According to some embodiments of the present disclosure, as shown inFIGS. 1 to 5, in order to facilitate the fitting of the second microwave shielding member121and the first microwave shielding member110to define the microwave-heating resonant cavity130, the second microwave shielding member121may have a hemispherical or cuboid shape which is hollow and has an open bottom, such that the appearance of the split-type microwave oven may be diversified, and thus aesthetic needs of different users may be satisfied. For example, as shown inFIGS. 4 and 5, the upper surface of the first microwave shielding member110may be formed as a plane, such that when the lower end of the second microwave shielding member121is fitted with the first microwave shielding member110, the microwave-heating resonant cavity130for heating food may be defined.

According to some embodiments of the present disclosure, as shown inFIGS. 1 to 3, the microwave shielding and choking member150is disposed in a remaining portion of the upper surface of the first housing assembly105. Herein, “a remaining portion of the upper surface of the first housing assembly105” refers to a portion of the upper surface of the first housing assembly105located outside the microwave-heating resonant cavity130. Further, the microwave shielding and choking member150is formed as an annular member, which is hollow and has an opening151in a top thereof. When the second microwave shielding member121is fitted with the microwave shielding member110, the lower surface of the second microwave shielding member121encloses the opening151.

For example, as shown inFIGS. 1 to 3, the microwave shielding and choking member150is formed as an annular groove in the upper surface of the first microwave shielding member110, the opening151of the annular groove faces upward (i.e. “up” shown inFIGS. 1 to 3), and the lower end of the second microwave shielding member121extends towards the outside of the microwave-heating resonant cavity130to form a flanging124. When the second microwave shielding member121defines the microwave-heating resonant cavity130together with the first microwave shielding member110, a lower end surface of the flanging124encloses the opening151of the annular groove. Thus, the reliability of the microwave shielding and choking member150is improved, and also it is convenient for the use of the user.

According to another embodiment of the present disclosure, as shown inFIGS. 4 to 5, the microwave shielding and choking member150is disposed on the lower end of the second microwave shielding member121. Thus, the microwave leakage between the second microwave shielding member121and the first microwave shielding member110may be effectively prevented. The microwave shielding and choking member150is formed as an annular member, which is hollow and has an opening151in a bottom thereof. When the second microwave shielding member121is fitted with the first microwave shielding member110, the first microwave shielding member110encloses the opening151. As shown inFIG. 4, the microwave shielding and choking member150has a substantially rectangular section, and the opening151faces the first microwave shielding member110. Thus, the structure of the microwave shielding and choking member150may be simplified, and also the microwave leakage may be effectively prevented.

In addition, the detection device may be configured as a sensor for detecting an amount of microwaves outside the microwave-heating resonant cavity130. Thus, the production cost may be saved, and the competitiveness of products may be improved. It should be noted that the structure of the detection device is not limited to this. For example, the detection device may include an emitter for emitting a microwave signal and a receiver for receiving a standing wave. When the second microwave shielding member121is fitted with the first microwave shielding member110to define the microwave-heating resonant cavity130, the emitter emits the microwave signal into the microwave-heating resonant cavity130, and the receiver is used to receive the reflected standing wave. If the microwave signal emitted by the emitter is same with the microwave signal received by the receiver, it is proved that there is no microwave leakage; otherwise, it is proved that there is the microwave leakage. Thus, the detection device may accurately detect whether the microwave leakage occurs at the microwave-heating resonant cavity130, such that the safety of the split-type microwave oven100is improved, and the use requirement of the user is satisfied.

In addition, as shown inFIGS. 1 to 3, in order to facilitate removing or placing the second housing assembly120by the user, the second housing assembly120may be provided with a handle125. For example, as shown inFIGS. 1 to 3, the handle125may be provided to an upper portion of the second housing assembly120. In an embodiment of the present disclosure, the power source142may be configured as a magnetron power source142. Certainly, the type of the power source142is not limited to this. For example, the power source142may also be a semiconductor power source142. Thus, the power source142may be suitable for split-type microwave ovens100of different models, and the use requirements of different users may be satisfied.
