Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

Next, a lid assembly and a cooking appliance according to the present invention will be described with reference to fig. 1 to 7. It can be understood, according to the utility model discloses a cooking utensil can be for electric rice cooker, electric pressure cooker or other cooking utensil, and according to the utility model discloses a cooking utensil except having the function of cooking rice, can also have various functions such as cooking congee, a kind of deep pot hot water.

The following describes in detail the overflow preventing device and the cooking appliance according to the present invention, taking an electric rice cooker as an example. As shown in fig. 1, the cooking appliance 200 of the present embodiment includes a pot body (not shown), an inner pot 210, and a cover assembly 100. Wherein the inner pot 210 is disposed in the pot body, and the inner pot 210 can be freely put into or taken out of the pot body, so as to facilitate the cleaning of the inner pot 210. The inner pot 210 is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc.

As shown in fig. 1-4, the cap assembly 100 includes a cap body 110 and a overfill prevention device 120. As shown in fig. 1, the cover 110 of the cover assembly 100 covers the upper portion of the pot body and forms a cooking space of the cooking utensil 200 with the inner pot 210. The overfill prevention device 120 is disposed in the cover 110. Specifically, in the illustrated embodiment, the cover 110 includes a liner 111, a removable cover 112, and a face cover (not shown). The inner liner 111 is disposed over the removable cover 112 and the face cover is disposed over the inner liner 111. The detachable cover 112 is disposed at a side of the cover body 110 facing the pot body to close the inner pot 210 when the cover body 110 is closed to the pot body.

As shown in fig. 5A and 5B, the overfill prevention device 120 includes a first electrode 121, a second electrode 122, and an insulative mount 123. The first electrode 121 and the second electrode 122 are spaced apart in the first direction D1 (fig. 2) and surrounded by the insulating mounting seat 123, and distal ends of the first electrode 121 and the second electrode 122 are respectively exposed from a bottom surface of the insulating mounting seat 123 for contacting with the liquid in the cooking utensil 200. That is, in the illustrated embodiment, the first electrode 121 and the second electrode 122 are both disposed inside the insulative mounting seat 123 in the circumferential direction. In the illustrated embodiment, the first electrode 121 and the second electrode 122 have substantially the same shape and size to facilitate processing. However, the shapes and sizes of the first electrode 121 and the second electrode 122 may also be different. In the cooking process, in the state that liquid (such as water) is heated to boiling or tends to boiling, the liquid level is continuously raised due to the generation of bubbles. When the liquid level of the liquid rises to be simultaneously contacted with the first electrode 121 and the second electrode 122, the first electrode 121 and the second electrode 122 are conducted through the liquid and form a closed loop, and electrical signals such as current or voltage are changed, so that a cooker overflow signal can be output. As the intensity of boiling increases, the current flowing between the first electrode 121 and the second electrode 122 through the liquid changes. Therefore, the control system can judge whether the liquid contacts the electrode or not by detecting the change of the current, namely the change of the current is used as a pot overflow signal, thereby finishing the judgment of pot overflow. However, the control system of the cooking appliance 200 may generate and acquire the overflow signal in other manners.

Also, the control system of the cooking appliance 200 may also be responsive to the overflow prevention signal to further prevent overflow during cooking. For example, after detecting the overflow signal generated by the overflow prevention device 120, the heating parameters of the heating device are adjusted such that the heating power of the cooking device is reduced and the thermal movement of the liquid in the cooking appliance 200 is reduced, thereby preventing the overflow phenomenon. However, the control system of the cooking appliance 200 may control the heating of the cooking appliance 200 in other ways to prevent overflowing. Preferably, the first electrode 121 and the second electrode 122 are integrally provided as a one-piece, unitary member with the insulative mounting base 123. First electrode 121 and second electrode 122 are disposed within insulative mount 123, for example, by an insert injection molding process, and form a unitary, one-piece member. The top ends of the first electrode 121 and the second electrode 122 are respectively exposed from the top surface of the insulating mounting seat 123, so as to be electrically connected to the electrode lines. Therefore, the number of parts is reduced, the structure is more compact, and the installation and the replacement are convenient.

Referring again to fig. 2 and 3, preferably, the cover assembly 100 further includes a seal 130, the seal 130 being disposed to the junction of the insulative mount 123 and the cover 110. In the illustrated embodiment, the sealing member 130 is a sealing ring that substantially matches the shape of the outer ring of the insulative mounting seat 123, thereby preventing liquid that tends to overflow the pot from entering the inside of the cover 110, and improving the sealing effect. However, the type of the seal 130 is not limited to this embodiment.

As shown in fig. 5A, 5B and 6, the insulative mounting seat 123 is substantially cylindrical in shape, and is provided with through holes that are fitted with the first electrode 121 and the second electrode 122, so that the first electrode 121 and the second electrode 122 can be disposed inside the insulative mounting seat 123. Obviously, the insulating mounting seat 123 is made of an insulating material, so as to avoid interference of other metal substances or impurities on the first electrode 121 and the second electrode 122. One end of the insulating mounting seat 123 is provided with a flared structure 123a, the flared structure 123a is flared, a concave chamber 123D is formed at the bottom of the insulating mounting seat 123, and the size of the concave chamber 123D gradually increases toward the inner pot 210 along a second direction D2 (fig. 2) perpendicular to the first direction D1. The concave chamber 123d is mainly used for collecting or condensing bubbles or vapor generated by boiling of the liquid in the cooking appliance 200 therein, so that the liquid is better contacted with the first electrode 121 and the second electrode 122 of the overflow preventing device 120. Therefore, the overflow judgment can be made under the condition that the liquid level of the liquid rises in a small range, and the sensitivity of the overflow judgment is improved. It is understood that, in the present embodiment, the radial direction of the columnar body is the first direction D1, and the axial direction is the second direction D2.

Preferably, as shown in fig. 5A and 5B, the insulative mounting seat 123 further includes a connecting portion 123B, and the connecting portion 123B is disposed at a top end of the insulative mounting seat 123, i.e., an end opposite to the flared structure 123a, for connecting the overfill prevention device 120 to the cover body 110. In the illustrated embodiment, the connection portions 123b are oppositely disposed at both sides of the insulative mounting seat 123, enhancing the structural stability of the coupling of the overfill prevention device 120 and the cover body 110. The attachment portion 123b is configured as a flange extending outwardly from the insulative mounting block, for example, threaded holes may be provided in the flange to removably secure the overfill prevention device 120 to the cover 110 by way of a threaded connection. Alternatively, a snap may be provided on the connecting portion 123b to detachably fix the spill prevention unit 120 to the cover 110 by means of snap. However, the connection manner of the overflow preventing means 120 and the cover body 110 is not limited to the above-described embodiment.

As shown in fig. 2, the connection 123b of the spill guard 120 is arranged on the side of the inner liner 111 facing away from the inner pot 210, the spill guard 120 extending at least partially into the inner pot 210 through the inner liner 111 and the removable cover 112.

As shown in fig. 7, the first electrode 121 and the second electrode 122 preferably extend in the insulating mount 123 and into the flared end structure 123a along the second direction D2 (fig. 2). The arrangement is such that the first electrode 121 and the second electrode 122 can easily contact with the liquid formed by the condensation of the vapor in the flared structure 123a, which is beneficial to improving the sensitivity of sensing by the first electrode 121 and the second electrode 122.

As shown in fig. 5A and 7, it is preferable that a baffle 123c is disposed in the flared structure 123a of the insulative mounting seat 123, and the baffle 123c divides the recess 123D into two regions, so that the first electrode 121 and the second electrode 122 are disposed on two sides of the baffle 123c along the first direction D1 (fig. 2), i.e., in the two regions, respectively. Accordingly, the baffle 123c and the insulating mounting seat 123 are made of insulating materials, so as to prevent the first electrode 121 and the second electrode 122 from being unintentionally touched and conducted in the flared end structure 123a, thereby avoiding misjudgment of the pot overflow, and improving the accuracy of the pot overflow judgment. In the illustrated embodiment, the baffle 123c is disposed at a middle portion of the flared structure 123a of the insulative mounting block 123 and is connected to opposite sidewalls of the flared structure 123 a. It will be appreciated by those skilled in the art that the baffles 123c may also act as reinforcing ribs to enhance the structural strength of the overfill prevention device 120, so that the overfill prevention device 120 works better.

Preferably, as shown in fig. 6, the first electrode 121 and the second electrode 122 have the same structure. For example, in the illustrated embodiment, the first electrode 121 and the second electrode 122 respectively have a first body 121a and a second body 122a in the shape of a round needle extending along the first direction D1 (fig. 2), so that the liquid condensed on the first electrode 121 and the second electrode 122 flows down smoothly, and the influence of long-time liquid accumulation on the overflow judgment is avoided. And, the cross-sectional shapes of the first electrode 121 and the second electrode 122 are circular to facilitate processing, thereby reducing the production cost. The tops of the first body 121a and the second body 122a are respectively provided with a first fixing portion 121b and a second fixing portion 122b, which increase the contact surface area of the electrode end and facilitate electrical connection with an electrode wire (not shown). The ends of the first body 121a and the second body 122a are exposed from the bottom surface of the insulating mounting seat 123. The first fixing portion 121b and the second fixing portion 122b are exposed from the top surface of the insulative mounting base. However, in an embodiment not shown, the first electrode 121 and the second electrode 122 may have different structures.

Preferably, the first electrode 121 is spaced apart from the second electrode 122 by a distance greater than 3 mm. For example, the first electrode 121 and the second electrode 122 may be spaced apart by 3.5mm or 4mm, etc. At this distance, on one hand, the anti-overflow device 120 can be ensured to have a fast reaction speed to the steam and the condensed liquid, so that the anti-overflow device 120 has a high liquid boiling detection sensitivity, and on the other hand, the anti-overflow device 120 can be prevented from being too sensitive, so that the false judgment is caused and the anti-overflow control is operated incorrectly.

Since the first electrode 121 and the second electrode 122 are always conducted and form a closed loop in an operating state, in which an anode reaction occurs and corrosion occurs on the electrode serving as an anode, in order to prevent the above situation, at least one of the first electrode 121 and the second electrode 122 is preferably made of a pure titanium metal material. The pure titanium metal has electrical corrosion resistance and stability, so that the operating performance of the overflow preventing device 120 is more stable.

The utility model also provides a cooking utensil 200, it includes aforementioned lid subassembly 100. The specific structure has been described in detail above, and for brevity, will not be described again.

According to the cover assembly 100 and the cooking utensil 200 for the cooking utensil of the present invention, the first electrode 121 and the second electrode 122 are disposed in the cover 110, so that the cover can be turned on when contacting with the liquid in the cooking utensil 200, and a signal can be sent to the control module of the cooking utensil 200, so that the cooking utensil 200 can take corresponding measures to prevent the liquid in the pot from overflowing, and a good anti-overflow effect is achieved; in addition, the first electrode 121 and the second electrode 122 are uniformly arranged inside the insulating mounting seat 123, so that the manufacturing difficulty can be reduced, and the installation is convenient.
