In addition, in this context, it will also be understood that when an element is referred to as being "on" or "under" another element, it can be directly on "or" under "the other element or be indirectly on" or "under" the other element via an intermediate element.

The present application provides a cooking appliance including but not limited to a rice cooker, an electric steamer, a health preserving pot and the like. The following description will be given taking a cooking appliance, specifically, a liquid heating container, as an example.

As shown in fig. 1, when the cooking appliance is a liquid heating container, the cooking appliance comprises a body 1, a base 2 and a lid 5, the body 1 has a first cavity 11, the first cavity 11 is used for containing liquid to be heated, and the lid 5 can close the cavity; the base 2 is located at the bottom of the body 1, and the base 2 has a control panel 4 and a heating element 7, the control panel 4 is used for controlling the cooking device to work or stop working, and the heating element 7 is used for heating the liquid in the first cavity 11. The cooking appliance further includes a handle 6 fixed to the body 1, and the user can move the cooking appliance through the handle 6.

The cooking appliance further comprises an upper connector and a lower connector for electrical connection, wherein the lower connector is connected to a power supply, the upper connector is connected to the heating member 7, and the heating member 7 can be energized when the lower connector is coupled to the upper connector, so that the heating member 7 can heat the liquid in the first cavity 11.

The cooking apparatus may further include a sealing member 3, and the sealing member 3 may be used to seal electronic components such as a control board 4 and a connector of the cooking apparatus. When the user washes the cooking appliance, the sealing member 3 can reduce the risk of liquid entering the sealing member 3 to contact with the control board 4, the connector and other electronic devices, thereby reducing the risk of short circuit of the electronic devices. The control board 4 may be a circuit board, such as a Printed Circuit Board (PCB). However, when the sealing performance of the sealing member 3 is deteriorated due to aging of the components, abnormal use or other accidental means, water is liable to enter the sealing member 3 to contact the control board 4 (or other electronic devices) during washing of the cooking appliance, so that the control board 4 or other electronic devices are damaged, and there is a serious safety risk in that the user continues to use the cooking appliance.

To solve this technical problem, the base 2 in the present application has a second cavity 31 isolated from the first cavity 11 of the body 1, and the second cavity 31 is used for accommodating electronic devices such as the control board 4. When the cooking appliance includes the sealing member 3, the second cavity 31 is provided to the sealing member 3. When the sealing function of the sealing component 3 is normal, the isolated first cavity 11 and the isolated second cavity 31 can prevent the liquid in the first cavity 11 from entering the second cavity 31, so as to protect the electronic device in the second cavity 31. Meanwhile, the cooking apparatus further includes a detecting member 32 and a supporting member 35, the detecting member 32 is electrically conductive, at least a portion of the detecting member 32 is located in the second cavity 31, the supporting member 35 is located in the second cavity 31 and supports the detecting member 32, and under the action of the liquid, one of the shape, the position and the volume of the detecting member 32 can be changed, so that the detecting member 32 is turned on or off, thereby detecting whether the liquid (e.g., water) exists in the second cavity 31 of the sealing member 3.

Therefore, in the present embodiment, by the arrangement of the detecting member 32 and the supporting member 35, it is possible to easily detect whether water is present in the second chamber 31, thereby determining whether the cooking appliance is safe and preventing the cooking appliance from being damaged by the energization when water is present in the second chamber 31. Meanwhile, the water in the second cavity 31 acts on the supporting member 35, so that the detection member 32 is turned on or off by changing one of the shape, position and volume of the supporting member 35, and the reliability of turning on or off the detection member 32 is improved.

Specifically, as shown in fig. 1, the cooking appliance further includes a control board 4, the control board 4 is located in the second cavity 31 of the sealing member 3, and the detection member 32 is connected to the control board 4 (including electrical connection or signal connection). At this time, the on or off of the detecting member 32 can control the on or off of the control circuit of the cooking appliance, or the on or off of the detecting member 32 can transmit a signal to the control board 4, so that the control board 4 can control the on or off of the control circuit according to the corresponding signal.

In this embodiment, when the detecting member 32 detects that there is liquid in the second cavity 31, the control board 4 can make the control circuit be in the off state according to the detection result, so that when there is liquid in the second cavity 31, the cooking appliance can automatically stop the operation of the heating member 7, manual control is not needed, and the safety of the cooking appliance is further improved.

Specifically, the control board 4 can detect the on or off state of the detection piece 32, thereby determining whether the on state of the detection piece 32 has changed. Alternatively, the detecting member 32 can form a closed loop with the entire control circuit, and the conductive state of the entire control circuit can be directly controlled by the conductive state of the detecting member 32.

In one embodiment, the detecting element 32 may form a closed loop with the entire control circuit, and when the detecting element 32 is in an open state, the control circuit is turned on; when the detecting member 32 is turned on, the control circuit is turned off.

In another embodiment, the detecting element 32 and the whole control circuit form a closed loop, and when the detecting element 32 is in a conducting state, the control circuit is conducted; when the detection member is opened, the control circuit is opened.

In a first embodiment, the detecting member 32 may comprise a switch electrically or signally connected to the control board 4, for example, the switch may be a micro switch, a reed switch, or the like, and the switch may be a normally closed switch. When there is no liquid in the second cavity 31, the switch is in a conducting state and can transmit a starting signal to the control board 4, so that the control circuit of the cooking appliance is controlled to be conducted through the control board 4, and at this time, the cooking appliance can normally work (the heating component 7 can heat the liquid in the first cavity 11); when there is liquid in the second cavity 31, the switch is in an off state and can transmit a closing signal to the control board 4, so that the control circuit of the cooking appliance is controlled to be turned off by the control board 4, the heating part 7 cannot be heated, potential safety hazards caused by continuous use of a user when liquid exists in the sealing part 3 are prevented, user safety is guaranteed, and the cooking appliance is prevented from being damaged.

In this embodiment, when the detecting member 32 is a switch, the detecting member 32 is in signal connection with the control board 4, so that the number of wires for electrically connecting the detecting member 32 and the control board 4 can be reduced, and the structure of the cooking apparatus can be simplified.

In one embodiment, as shown in fig. 1-5 and 8-9, for example, the cooking apparatus includes two detecting members 32, the supporting member 35 supports at least one of the two detecting members 32, and when the two detecting members 32 are spaced apart and in the off state, it is determined that no liquid (e.g., water) exists in the second cavity 31 of the sealing member 3. When the sealing performance of the sealing component 3 fails and water enters the second cavity 31 during the cleaning process, the liquid (e.g., water) can increase the volume of the supporting member 35, the supporting member 35 pushes at least one detecting member 32 to approach toward another detecting member 32, so that the two detecting members 32 are in contact and in a conducting state, and at this time, the detecting member 32 determines that the liquid (e.g., water) exists in the second cavity 31 of the sealing component 3.

In another embodiment, taking the example that the cooking apparatus includes two detecting elements 32, the supporting element 35 supports at least one detecting element 32 of the two detecting elements 32, and under the supporting action of the supporting element 35, the two detecting elements 32 are in contact and kept in a conducting state, and at this time, it is determined that no liquid (for example, water) exists in the second cavity 31 of the sealing member 3. When the sealing performance of the sealing component 3 fails and water enters the second cavity 31 during the cleaning process, since the liquid (e.g. water) can reduce the volume (height) of the supporting member 35, at least one of the detecting members 32 descends along with the descending of the height of the supporting member 35 and moves away from the other detecting member 32, so that the two detecting members 32 are disconnected, and at this time, the existence of the liquid (e.g. water) in the second cavity 31 of the sealing component 3 is determined.

In the first embodiment, the detecting element 32 includes a first detecting element 321 and a second detecting element 322, when the volume of the supporting element 35 is reduced by the liquid, the sealing performance of the sealing element 3 is normal, and there is no liquid in the sealing element 3, the first detecting element 321 contacts and is conducted with the second detecting element 322 under the supporting action of the supporting element 35 (i.e. under the normal working condition, the two detecting elements 32 and the control board 4 are in the conducting state), at this time, the detecting element 32 sends a signal to the control board 4, the control board 4 determines that there is no liquid in the second cavity 31, and the control board 4 maintains the control circuit conducting, i.e. the cooking appliance can work normally (the heating element 7 can heat the liquid in the first cavity 11). After the sealing performance of the sealing component 3 is failed, when a user cleans the cooking appliance, liquid and/or vapor can enter the sealing component 3, so that liquid exists in the sealing component 3, the volume of the supporting component 35 is reduced after the supporting component is contacted with the liquid (such as water), so that the first detection component 321 and the second detection component 322 are far away from each other and disconnected, at the moment, the detection component 32 sends a signal to the control panel 4, the control panel 4 judges that the liquid exists in the second cavity 31, so that the control circuit is disconnected, the heating component 7 cannot be heated, and therefore the potential safety hazard caused by the fact that the user continues to use when the liquid exists in the sealing component 3 is prevented, the safety of the user is guaranteed, and the cooking appliance is prevented from being damaged.

Specifically, as shown in fig. 1 to 7, the first detecting element 321 is an elastic sheet with one end bent downward and made of metal, the first detecting element is provided with a recess 325, the recess 325 is recessed toward a direction away from the second detecting element 322, the recess 325 is formed by bending the first detecting element 321, the first detecting element 321 has elastic force, the direction of the elastic force is away from the second detecting element, when the sealing performance of the sealing element 3 is failed, when a user cleans the cooking appliance, liquid and/or vapor can enter the sealing element 3, so that the liquid is present in the sealing element 3, the volume of the supporting element 35 is reduced after contacting with the liquid (such as water), so that the first detecting element 321 is away from the second detecting element 322 under the effect of the elastic force, and the first connecting element 321 is disconnected from the second connecting element 322.

Specifically, the sealing member 3 may have a plurality of sealing failures, and therefore, a plurality of supporting members 35 may be provided, each supporting member 35 supporting at least one detecting member 32 such that the detecting member 32 is in contact with or spaced apart from another detecting member 32. Each support member 35 is disposed at different positions of the bottom wall of the sealing member 3, and can detect a plurality of positions simultaneously, each support member 35 supports at least one detection member 32, and the more the detection members 32 and the support members 35 are disposed, the greater the probability that the liquid (such as water) meets the support member 35, and the more accurate the detection of the sealing performance of the sealing member 3.

In the second embodiment, the detecting element 32 includes a first detecting element 321 and a second detecting element 322, and the supporting element 35 is supported between the first detecting element 321 and the second detecting element 322, so that the first detecting element 321 and the second detecting element 322 are not in contact with each other. When the sealing performance of the sealing member 3 is normal and there is no liquid in the sealing member 3, the detecting member 32 is in an off state (i.e. the first detecting member 321 and the control board 4 are in an off state in a normal operating state), at this time, the detecting member 32 sends a signal to the control board 4, the control board 4 determines that there is no liquid in the second cavity 31, and the control board 4 maintains the control circuit on, that is, the cooking apparatus can operate normally (the heating member 77 can heat the liquid in the first cavity 11). After the sealing performance of the sealing component 3 is invalid, when a user cleans the cooking appliance, liquid and/or vapor can enter the sealing component 3, so that liquid exists in the sealing component 3, the supporting component 35 is dissolved after being contacted with the liquid (such as water), so that the first detection component 321 is contacted with the second detection component 322 and conducted, at the moment, the detection component 32 sends a signal to the control board 4, the control board 4 judges that the liquid exists in the second cavity 31, so that the control circuit is disconnected, the heating component 7 cannot be heated, so that the potential safety hazard caused by continuous use of the user when the liquid exists in the sealing component 3 is prevented, the safety of the user is guaranteed, and the cooking appliance is prevented from being damaged.

In the above two embodiments, the supporting member 35 has a property of rapidly reducing volume after contacting with liquid, the liquid is water for example, the material of the supporting member 35 may include one or more of acrylic acid, polyvinyl alcohol copolymer, potassium permanganate, and chloride, at this time, the supporting member 35 is stable and has good supporting property when having a solid state, and at the same time, the supporting member 35 has a characteristic of fast dissolution speed when meeting water, and can rapidly react with water in the sealing member 3 as the supporting member 35, thereby improving the detection sensitivity, and the cost is low.

In a third specific embodiment, as shown in fig. 1-7, the detecting element 32 includes a first detecting element 321 and a second detecting element 322, wherein the supporting element 35 supports the first detecting element 321, when the supporting element 35 has a volume increased by the liquid, as described above, the sealing performance of the sealing element 3 is normal, and no liquid is in the sealing element 3, a gap is formed between the first detecting element 321 and the second detecting element 322, and the gap is in an off state (i.e. the detecting element 32 and the control board 4 are in an off state in a normal operating state), at this time, the detecting element 32 sends a signal to the control board 4, the control board 4 determines that no liquid is in the second cavity 31, and the control board 4 maintains the control circuit to be on, i.e. the cooking appliance can operate normally (the heating element 77 can heat the liquid in the first cavity 11). After the sealing performance of the sealing component 3 is invalid, when a user cleans the cooking appliance, liquid and/or vapor can enter the sealing component 3, so that liquid exists in the sealing component 3, the volume of the supporting component 35 is increased after the supporting component is contacted with the liquid (such as water), the two detection pieces 32 are conducted under the action of the supporting component 35, at the moment, the detection pieces 32 send signals to the control board 4, the control board 4 judges that the liquid exists in the second cavity 31, so that the control circuit is disconnected, the heating component 7 cannot be heated, so that the potential safety hazard caused by continuous use of the user when the liquid exists in the sealing component 3 is prevented, the safety of the user is ensured, and the cooking appliance is prevented from being damaged.

In the third embodiment, the supporting member 35 has a property of rapidly increasing volume after contacting with liquid, the liquid is water for example, the material of the supporting member 35 includes one or more of water-swellable rubber, water-absorbent resin and porous material, and the supporting member is stable and good in supporting property when in a solid state, rapidly swells after contacting with water, can rapidly react to water in the sealing member 3 as the supporting member 35, improves detection sensitivity, and is low in cost.

Specifically, as shown in fig. 4 and 5, the rib 331 is provided with a plurality of openings 331b, and the support 35 is provided with a second protrusion 351, the second protrusion 351 being capable of protruding from the openings 331b to enable the second protrusion 351 to be in contact with the liquid entering the second cavity 31, while the second protrusion 351 is adapted to the openings 331b, so that the support 35 and the rib 331 are connected to the openings 331b through the second protrusion 351, thereby improving the mounting reliability of the support 35.
