For example, in one embodiment, a cylindrical inner pot accommodating portion may be provided on the pot body 40, and the inner pot 41 may be freely put into or taken out from the inner pot accommodating portion. The detachable setting mode enables the user to conveniently take out the inner pot 41 for cleaning. Certainly, in other embodiments, the inner pot 41 may also be fixedly arranged in the pot body 40 in a non-removable manner. Usually, a heating device for heating the inner pot 41 is also arranged in the pot body 40 .

As shown in FIG. 1 , the cover body 10 is arranged on the pot body 40 in an openable and closable manner. Therefore, the cover body 10 generally has a shape that is adapted to the shape of the pot body 40 , so that the pot body 40 can be conveniently covered. In this embodiment, the cover body 10 may be pivotally connected to the pot body 40 through a pivot shaft (not shown). The pivot axis defines a pivot axis AX as shown in FIG. 2 . When the cover 10 is opened relative to the pot body 40 , the opening of the inner pot 41 in the pot body 40 is exposed, and the user can add ingredients to the inner pot 41 or take out cooked food from the inner pot 41 .

A sealing member is also provided between the cover body 10 and the inner pot 41, so that the cooking space can maintain a good airtightness.

The cooking appliance 1 according to the invention is also provided with steam generating means. As shown in FIG. 2 , a steam generating device 20 is disposed in the cover body 10 and is used to generate steam for assisting cooking. Correspondingly, as shown in FIG. 4 , a first steam channel 11 is provided on the cover body 10 . When the cover body 10 covers the pot body 40 , the steam generating device 20 can communicate with the cooking space through the first steam channel 11 , so as to introduce steam into the cooking space to assist cooking. Taking an electric rice cooker as an example, the specific operation of auxiliary cooking may be that during the cooking process, the steam generated by the steam generating device 20 is introduced into the cooking space, and heated from above the rice, so that the rice can be heated evenly and the heating efficiency is improved; Alternatively, after the rice is cooked, the steam generated by the steam generating device 20 can be introduced into the cooking space to keep the rice warm and fresh, so as to maintain a good taste.

Specifically, as shown in FIGS. 2 to 4 , in this embodiment, the steam generating device 20 includes two parts: a steam generating component 21 and a steam sealing component 22 .

The steam generating component 21 is provided with a steam generating cavity 23 for containing water to be heated to generate steam. Preferably, the position of the steam generating chamber 23 can form a recessed receiving part (not shown), and a water container is arranged in the receiving part. The accommodating space of the water container constitutes the steam generating chamber 23 . Thus, the steam generating chamber 23 can be conveniently provided. Furthermore, the water container may be configured to be manually detachably arranged in the receiving portion. The user can conveniently take out the water container for cleaning or replacement. Certainly, the steam generating chamber 23 may also be configured in other forms, for example, configured as a recess integrally formed with the cover body 10 .

In addition, the steam generating assembly 21 also includes a heating device for heating the water in the steam generating chamber 23 to generate steam. Therefore, the heating device can preferably be arranged below or at the side of the steam generating chamber 23 . As shown in FIG. 4 , in this embodiment, the heating device 24 is configured to include a heating plate 241 and an electric heating tube 242 . Wherein, the heating tray 241 includes a bottom wall and a side wall extending upward from the edge of the bottom wall. Thus, the bottom wall and the side walls form a space for accommodating the water container and surround the water container from below and laterally. The electric heating tube 242 is arranged in the heating plate 241 . In the illustrated embodiment, the electric heating pipe 242 is disposed in the side wall of the heating pan 241 . However, the electric heating tube 242 can also be arranged in the bottom wall of the heating pan 241 , or the electric heating tube 242 can be arranged in both the side wall and the bottom wall. Of course, the heating device can also be configured in other forms, such as an electromagnetic heating device and the like.

The steam sealing assembly 22 is connected to the cover body 10 and can be opened and closed relative to the steam generating chamber 23 . 3 and 4 show that the steam sealing assembly 22 is in a closed state, and in this state, the steam sealing assembly 22 covers the steam generating chamber 23 . The vapor tight assembly 22 is shown in an open state in FIG. 2 . The user can observe the water level and cleanliness (whether there is scale, etc.) in the steam generating chamber 23 by opening the steam sealing assembly 22, and then decide whether to perform operations such as adding water or cleaning the steam generating chamber 23.

In one embodiment, the steam sealing assembly 22 can be configured in the form of a steam cover 25 , and the steam cover 25 is provided with a seal 26 at a position corresponding to the steam generating cavity 23 on the side facing the steam generating cavity 23 . When the steam sealing assembly 22 is in a closed state, the sealing member 26 is sandwiched between the steam cover plate 25 and the edge of the steam generating chamber 23 to play a sealing role and avoid steam leakage.

In order to introduce the steam generated in the steam generating chamber 23 into the cooking space in the state that the steam generating chamber 23 is sealed by the sealing member 26 , a second steam channel 251 is provided on the steam cover 25 . The second steam channel 251 has a second steam inlet 252 and a second steam outlet 253 . It can be understood that the second steam inlet 252 is located in the sealing area of the sealing member 26 , and the second steam outlet 253 is located outside the sealing area of the sealing member 26 . When the steam sealing assembly 22 is in a closed state, the second steam outlet 253 is connected to the first steam inlet 111 of the first steam channel 11 . As shown in FIG. 4, the steam generated in the steam generating chamber 23 can flow into the second steam channel 251 through the second steam inlet 252, continue to flow, and enter the first steam through the butted second steam outlet 253 and the first steam inlet 111. Channel 11. Finally, the first steam outlet 112 flowing out of the first steam channel 11 enters the cooking space below the cover body 10 .

As shown in FIG. 5 , the cooking appliance 1 further includes a detection device 30 for detecting the opening and closing state of the steam cover 25 . The detection device 30 includes a detection part 31 and a trigger part 32 . When the steam cover 25 is closed, the detection part 31 is triggered by the action of the trigger part 32 and is in the first state. When the steam cover 25 is opened, the trigger member 32 will not act on the detection member 31 , and the detection member 31 is in the second state of being untriggered. Thus, the current opening and closing state of the steam cover 25 can be judged by the state of the detection member 31 .

Usually, a control device (not shown) is provided inside the cooking appliance 1 to control its operation. Preferably, the detection element 31 of the detection device 30 can be electrically connected to the control device. The control device recognizes the current state of the detection part 31 according to the signal sent by the detection part 31 , and then judges the opening and closing state of the steam cover 25 . Preferably, the control device can be configured to control the cooking appliance 1 to prohibit its operation when the detection member 31 is in the second state (that is, the steam cover 25 is opened). At this time, even if the user presses the button to start cooking, the cooking appliance 1 cannot perform cooking operations such as heating, thereby ensuring safety.

Although not shown in the figure, it can be understood that the cooking appliance can also be provided with a prompting device. The prompting device is configured to be able to issue prompting information corresponding to the state of the detecting element 31 according to the different states. Specifically, when the detecting member 31 is in the first state, the prompting device sends a prompting message that the steam cover 25 is closed. When the detecting member 31 is in the second state, the prompting device sends a prompting message that the steam cover 25 is opened. According to different user groups, the prompt information may be at least one of text information, sound information, and light information. Correspondingly, the prompting device can be configured in the form of a display screen, a loudspeaker, or a signal light.

Further preferably, the prompting device can be electrically connected with the control device. The control device coordinates the work of each device, and controls the prompt device to send corresponding prompt information according to the judgment result, thereby simplifying the control procedure.

Specifically, in the first embodiment shown in FIG. 5 , the detecting part 31 is configured as a micro switch, and correspondingly, the triggering part 32 is configured in the form of a trigger rod for triggering the micro switch. In the following description, the detection part 31 can also be called a micro switch 31 , and the trigger part 32 can also be called a trigger lever 32 . Both the micro switch 31 and the trigger lever 32 are disposed on the cover 10 . Wherein, the trigger lever 32 is movably arranged vertically, and the micro switch 31 is arranged on the side of the trigger lever 32 . The trigger lever 32 is further provided with a pressing portion 34 extending toward the micro switch 31 at a position close to the middle of the trigger lever 32 .

As shown in FIG. 2 , the upper end of the trigger rod 32 protrudes from the upper surface of the cover body 10 . When the steam cover 25 is closed, it presses the upper end of the trigger lever 32 to move downward, at this time, the pressing part 34 of the trigger lever 32 moves downward together, and gradually touches the direction of the trigger lever 32 of the micro switch 31 The lifted reed makes the reed move toward the body of the micro switch 31 and contact another electrode on the body of the micro switch 31 . At this time, the microswitch 31 changes from the off state (corresponding to the second state of the detection element) to the on state (corresponding to the first state of the detection element). In other words, currently the micro switch 31 is in the first state of being triggered, it can be judged that the steam cover 25 is currently closed.

In addition, the detection device 30 also includes an elastic member 33 , which acts on the trigger rod 32 to move in the opposite direction to the direction of triggering the micro switch 31 . When the steam cover 25 is opened, the pressing force acting on the trigger rod 32 disappears, and the trigger rod 32 moves to a position where the micro switch 31 cannot be triggered under the action of the elastic member 33 . At this time, the micro switch 31 changes from the on state to the off state. In other words, the micro switch 31 is currently in the second state of being untriggered, and it can be judged that the steam cover 25 is currently open.

In this embodiment, the micro switch 31 is arranged on the side of the trigger lever 32, so that the space inside the cover body 10 can be rationally utilized, and the thickness of the cover body 10 caused by the arrangement of various parts along the vertical direction can be avoided. Of course, when the thickness of the cover body 10 can meet the installation requirements, the micro switch 31 can also be arranged under the trigger lever 32, so that the pressing part 34 can be omitted, and the body of the trigger lever 32 can be used to directly trigger the micro switch. Switch 31. In addition, it is also possible to choose to directly and fixedly arrange the trigger lever 32 on the steam cover 25 . Those skilled in the art can reasonably select and design a specific triggering method according to needs, as long as the trigger rod 32 triggers the microswitch 31 as the steam cover 25 is closed.

Fig. 6 shows a cooking appliance 2 according to a second embodiment of the invention. Among them, the cooking appliance 2 according to the second embodiment has substantially the same configuration as the cooking appliance 1 according to the first embodiment shown in FIGS. 1 to 5 except for the structure of the detection device. Therefore, only the cover body 210 is shown in FIG. 6 , and the pot body is omitted.

In this embodiment, the detection device 230 includes a reed switch as the detection part 231 and a magnetic field generator as the trigger part 232 . In the following description, the detection part 231 may also be called a reed switch 231 , and the trigger part 232 may also be called a magnetic field generating device 232 . Wherein, the magnetic field generating device 232 may be a magnet, which is easy to obtain and has a low cost.

Specifically, the magnetic reed switch 231 is disposed on the cover 210 to facilitate electrical connection with the control device. The magnetic field generating device 232 is arranged on the steam cover 225 and moves along with it. Thus, the steam cover 225 can be easily removed for cleaning without considering the problem of electrical connection.

When the steam cover 225 is closed, the magnetic field generating device 232 moves together to a position close to the reed switch 231 . At this time, the reed switch 231 is located within the action range of the magnetic field generated by the magnetic field generating device 232 , and maintains a normally closed or normally open state under the action of the magnetic field. In other words, currently the magnetic reed switch 231 is triggered by the magnetic field generating device 232 to be in the first state, it can be judged that the steam cover 225 is currently closed.

When the steam cover 25 is opened, the magnetic field generating device 232 moves to a position away from the magnetic reed switch 231 accordingly. At this time, the reed switch 231 is located outside the range of the magnetic field of the magnetic field generating device 232 , and becomes normally open or normally closed under the action of the magnetic field loss. In other words, the current magnetic reed switch 231 is in the second untriggered state, and it can be judged that the steam cover 225 is currently open.

Generally, the steam cover 225 is pivotably opened and closed by a pivot shaft (not shown). Preferably, both the magnetic reed switch 231 and the magnetic field generating device 232 are disposed away from the pivot axis defined by the pivot shaft, so that when the steam cover 225 is opened, the magnetic field generating device 232 and the magnetic reed switch 231 maintain a sufficient distance, Make sure the reed switch 231 is out of range of the magnetic field.

Preferably, the upper surface of the cover body 210 is provided with a recessed portion that is recessed downwards to accommodate the steam generating device. When the steam cover 225 is closed, it fits into the recess. As a result, the cover body 210 can be made compact. On this basis, the magnetic reed switch 231 can be disposed on the inner side of the side wall of the recessed portion, that is, disposed on the side of the steam cover 225 . In this way, the space in the cover body 210 can be rationally utilized, and the thickness of the cover body 210 is prevented from being too large due to the arrangement of components along the vertical direction.

Fig. 7 shows a cooking appliance 3 according to a third embodiment of the invention. Among them, the cooking appliance 3 according to the third embodiment has substantially the same configuration as the cooking appliance 1 according to the first embodiment shown in FIGS. 1 to 5 except for the structure of the detection device. Therefore, only the cover body 310 is shown in FIG. 7 , and the pot body is omitted.

In this embodiment, the detection device 330 includes a detection electrode as a detection element 331 and a metal element as a trigger element 332 . In the following description, the detection part 331 may also be called a detection electrode 331 , and the trigger part 332 may also be called a metal part 332 . Wherein, the detection electrode 331 is disposed on the cover 310 and is electrically connected to the control device. The metal part 332 is disposed on the steam cover 325 and moves along with it.

When the steam cover 325 is closed, the metal part 332 moves to a position opposite to the detection electrode 331 . At this time, a capacitor structure can be formed between the metal piece 332 and the detection electrode 331 , and the capacitance value can be detected from the detection electrode 331 . As the steam cover 325 is closed, the facing area of the metal piece 332 and the detection electrode 331 increases and/or the relative distance decreases, and the detected capacitance value becomes larger. The state where the capacitance becomes larger can be regarded as the first state where the detection electrode 331 is triggered by the metal piece 332 , and it can be judged that the steam cover 325 is currently closed.

When the steam cover 325 is opened, the metal member 332 moves with it. As the facing area of the metal piece 332 and the detection electrode 331 decreases and/or the relative distance increases, the capacitance value detected from the detection electrode 331 becomes smaller. The state where the capacitance value becomes smaller can be regarded as the second state where the detection electrode 331 is not triggered, and it can be judged that the steam cover 325 is currently open.

Of course, the relative positions of the metal piece 332 and the detection electrode 331 can also be set so that when the steam cover 325 is closed, the facing area of the metal piece 332 and the detection electrode 331 decreases and/or the relative distance increases, correspondingly, When the steam cover 325 is opened, the facing area of the metal piece 332 and the detection electrode 331 increases and/or the relative distance decreases. At this time, the state where the capacitance value becomes larger is the second state where the detection electrode 331 is not triggered, and the state where the capacitance value becomes smaller is the first state where the detection electrode 331 is triggered by the metal piece 332 .

Preferably, in the process of closing or opening the steam cover 325, the change range of the facing area between the metal piece 332 and the detection electrode 331 is greater than or equal to 30 mm ² , so as to ensure that the obvious capacitance value can be detected by the detection electrode 331 Variety. For example, the change of the facing area of the two can be 40mm ² , 50mm ² , 60mm ² or 70mm ² .

As shown in FIG. 7 , in this embodiment, both the metal piece 332 and the detection electrode 331 are configured as flat plates and face each other in a plane-to-plane manner. However, in different implementations, the metal piece 332 and the detection electrode 331 can also be configured in the form of an arc plate. Alternatively, one of the metal piece 332 and the detection electrode 331 may be configured as a cylindrical structure, and the other may be configured as a cylindrical structure, and the capacitor is formed by extending the cylindrical structure into the cylindrical structure in the axial direction.
