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.

The utility model provides a cooking utensil. 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, fried dish. The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, a cooking appliance 1 according to the present invention includes a body 10 and a pot body 20. Wherein the body 10 is used to form a main frame structure of the cooking appliance 1, which is provided with a base 11. The pot body 20 can be placed on the base 11 and can be removed from the base 11. That is, wherein the pot body 20 is provided in a separable manner from the machine body 10 to facilitate the movement of the pot body 20. Therefore, the cooking appliance according to the present invention is constructed as a split type cooking appliance. In addition, the machine body 10 is provided with a storage bin 12. The storage bin 12 may comprise a solid storage bin that may be used to contain solid food materials that store rice, beans, etc. required for cooking. Further, the storage bin 12 may also include a liquid storage bin for containing a liquid such as water.

The pot body 20 includes a pot body seat 21, a pot body cover 22, and an inner pot 23 disposed in the pot body seat 21. The pot body seat 21 is detachably seated on the base 11 of the machine body 10. The inner pot 23 is removably placed in the pot body seat 21, and when the pot body cover 22 is closed to the pot body seat 21, a cooking space 24 is formed between the pot body cover 22 and the inner pot 23.

Further, the cooking appliance 1 further includes a feeding assembly 30. The delivery assembly 30 is used to deliver the ingredients and/or water in the storage bin 12 to the cooking space 24 of the pot body 20. For example, the feeding assembly 30 can automatically feed a predetermined amount of food and/or water into the cooking space 24 according to the operation instruction of the user, so as to automate the whole cooking process.

In this embodiment, the feeding assembly 30 may include a feeding arm having a feeding passage extending along a length thereof. It will be appreciated that the feed passage may comprise a solid feed passage for conveying food material and a liquid feed passage for conveying water. The material conveying arm is connected to the machine body, the solid material conveying channel is communicated with the solid material storage bin, and the liquid material conveying channel is communicated with the liquid material storage bin.

The feeding arm is movably arranged. For example, the feed arm can be moved into an abutting position with the pot body 20 to feed the material into the cooking space 24. This position may be referred to as a delivery position. The pot body 20 is provided with a port (not shown) communicating with the cooking space 24. When the feeding arm is moved to the feeding position, the feeding passage may communicate with the cooking space 24 of the pot body 20 through the mouthpiece, so as to feed the food and/or water as desired.

It is understood that the pot body 20 may not include the pot body cover 22. The inner pot 23 is set in an open state at this time. When the material conveying arm moves to the material conveying position, the material conveying channel can be directly communicated with the inner pot.

Further, as shown in fig. 1, when it is not necessary to feed the material into the cooking space 24, the feed arm may be moved from the feed position to a position away from the pot body 20. Thereby, a large taking and placing space is provided around the pot body 20. The user can conveniently take the pot body 20 off the base 11 or place the pot body 20 on the base 11. The position of the feeding arm away from the pot body 20 can be referred to as an initial position.

In the present embodiment, when the pot body 20 is positioned on the base 11, the storage bin 12, particularly the solid storage bin, is preferably positioned above the pot body 20. When the feeding assembly 30 is in the feeding position, the feeding passage communicates the storage bin 12 with the cooking space 24 in a substantially inclined posture. The conveying of the material can thus be effected automatically by means of gravity. Preferably, when the feeding assembly 30 is at the feeding position, the included angle between the feeding channel and the horizontal plane may be 15-90 °. The angle may be 30 °, 45 °, 60 °, 75 ° or any value within the above range, depending on the specific conditions of the size of the cooking appliance, the kind of the material to be conveyed, and the like.

The material conveying arm is preferably arranged to be pivotally movable about a substantially horizontally extending pivot axis. In other words, the feeding arm moves between the storage position and the feeding position in a vertically swinging manner. Therefore, it is preferable that the interface of the cooking space 24 is provided at the top of the pot body 20 so as to be interfaced with the feeding passage. In other words, the mouthpiece is preferably provided on the pot body cover 22. Further preferably, the pivot axis is located at one end of the feeding arm. Therefore, the swing radius of the feeding arm is larger, and the moving range is larger, so that the initial position can be set to be a position farther from the pot body 20, and the pick-and-place space around the pot body 20 is further increased.

With continued reference to fig. 1, the base 11 of the machine body 10 is provided with a heating device 13. When the pot body 20 is seated on the base 11, the heating means 13 can heat the pot body 20, specifically, the inner pot 23. The heating device 13 may be configured as a heating pan which generates heat by means of an electric heating tube or wire and transfers the heat to the inner pot 23.

In order to have a good heat transfer efficiency between the heating device 13 and the inner pot 23, according to the present invention, the pot body 20 includes a heat transfer plate 25 which is disposed at the bottom of the pot body 20 and is in contact with the inner pot 23. Thus, it can be understood that the pot body holder 21 surrounds the inner pot 23 substantially from the side of the inner pot 23, while the bottom of the inner pot 23 is supported by the heat conductive plate 25.

The heat conducting plate 25 is made of a material having a high heat transfer coefficient, such as metal. Specifically, the heat conductive plate 25 may be made of a material of aluminum, copper, silver, gold, zinc, iron, and/or steel, etc. When the pot body 20 is seated on the base 11, the lower surface of the heat conduction plate 25 is in contact with the heating means 13. Therefore, the heat generated by the heating device 13 can be transferred to the inner pot 23 in a heat conduction mode, so that the heat transfer efficiency is high, and a good heating effect is realized.

As shown in fig. 2, a support portion 211 is provided inside the pot body seat 21. Accordingly, the periphery of the heat conducting plate 25 is provided with a laterally outwardly extending flange 251. The support portion 211 supports the heat conductive plate 25 from below the flange 251.

Further, the pot body 20 further comprises a heat preservation ring 26. The heat preservation ring 26 is arranged in the pot body seat 21 and surrounds the inner pot 23 from the side part of the inner pot 23. In addition, a clamping groove 261 is arranged at the position close to the upper end of the heat preservation ring 26, and a clamping part 212 is arranged on the cooker body seat 21. The heat retaining ring 26 is connected to the pot body seat 21 by the way that the clamping portion 212 is clamped into the clamping groove 261. And the lower end of the heat retaining ring 26 is pressed against the upper surface of the flange 251 of the heat conductive plate 25 to further fix the heat conductive plate 25. In this way, when the pot body cover 22 covers the pot body seat 21, the pot body cover 22, the heat-insulating ring 26 and the heat-conducting plate 25 form a substantially closed space, and the inner pot 23 is surrounded in the space. Thus, heat emitted to the external environment due to thermal radiation and thermal convection can be reduced, and the heating efficiency can be improved.

Further, the heat retaining ring 26 is laterally spaced from the pot body seat 21 at positions other than the positions of the catching portion 212 and the catching groove 261. Therefore, the heat loss can be further reduced, and the heat preservation capability is improved.

As shown in fig. 3, the inner pot 23 has an inner pot attaching part 231, and the heat conductive plate 25 has a heat conductive attaching part 254. The inner pot 23 is in contact with the heat-conducting joint part 254 of the heat-conducting plate 25 through the inner pot joint part 231. This can make both have great area of contact to improve heat transfer efficiency.

Similarly, the heating device 13 configured as a heating pan has a heating attaching portion 131. The heat conduction plate 25 is in contact with the heating attachment portion 131 of the heating device 13 via the heat conduction attachment portion 254. And also can play a role in improving the heat transfer efficiency.

In order to achieve a large contact area in a limited size space, it is preferable that the joint portion of the inner pot 23, the heat conductive plate 25 and the heating means 13 includes an arc-shaped curved surface portion. Such as the inner pot arc 232 of the inner pot 23, the heat conductive arc 252 of the heat conductive plate 25, and the heating arc 132 of the heating device 13. Compared with pure plane contact, the arc shape can have larger contact area.

It is further preferred that the contacting of the inner pan arc-shaped portion 232, the heat conducting arc-shaped portion 252 and the heating arc-shaped portion 132 is configured such that the arc degree of the arc-shaped portion located on the side where the arc is convex is greater than or equal to the arc degree of the arc-shaped portion located on the side where the arc is concave. As shown in fig. 3, in the present embodiment, the bottom of the inner pot 23 is configured in a convex shape. Accordingly, the arc degree of the heating arc part 132 of the heating device 13 is greater than or equal to the arc degree of the heat conductive arc part 252 of the heat conductive plate 25, and/or the arc degree of the heat conductive arc part 252 of the heat conductive plate 25 is greater than or equal to the arc degree of the inner pot arc part 232 of the inner pot 23.

Of course, as shown in fig. 4, in another embodiment, when the bottom of the inner pot 23 ' is configured in a concave shape, the arc degree of the heating arc part 132 ' of the heating device 13 ' is set to be less than or equal to the arc degree of the heat conducting arc part 252 ' of the heat conducting plate 25 ' and/or the arc degree of the heat conducting arc part 252 ' of the heat conducting plate 25 ' is less than or equal to the arc degree of the inner pot arc part 232 ' of the inner pot 23 '.

Preferably, the base 11 of the machine body 10 is further provided with a temperature measuring device 14 for measuring the temperature of the inner pot 23. Whereby the heating power of the heating means 13, etc. can be controlled in dependence of the temperature level in the inner pot 23. It can be understood that when the temperature measuring point of the inner pot 23 is at the central position (e.g. the central position of the bottom of the inner pot 23), the temperature measurement is more accurate.

Typically, a temperature sensing cup (not shown) is provided on the outside of the temperature measuring device 14 to transfer heat to the element (e.g., a galvanic couple or resistance) that senses the temperature. And the temperature sensing cup has a relatively flat surface so as to be convenient for the inner pot 23 to be in close contact with the temperature sensing cup, so that the temperature measurement is accurate. Therefore, it is preferable that the inner pot attaching part 231 of the inner pot 23 further includes a plane part, such as the inner pot plane part 233 shown in fig. 3. Accordingly, the heat conductive plate 25 includes the heat conductive plane portion 253, and the heating device 13 has the heating plane portion 133 so as to be in close contact with each other. And the respective arc-shaped portions of the inner pot 23, the heat conducting plate 25 and the heating device 13 are arranged circumferentially around the planar portion, respectively.

Meanwhile, in order to conveniently dispose the temperature measuring device 14, as shown in fig. 3, the heating device 13 is provided with a first escape hole 134 at a position of the heating plane portion 133, and the temperature measuring device 14 protrudes upward from the first escape hole 134 so as to be in contact with the pot body 20 placed on the base 11.

In one embodiment, the thermometric device 14 may be in direct contact with the thermally conductive plate 25, which senses the temperature of the thermally conductive plate 25. Since the heat conduction plate 25 conducts heat to the inner pot 23, the temperature of the bottom of the inner pot 23 can be estimated approximately from the temperature of the heat conduction plate 25.

In another embodiment, a second avoiding hole may be further formed at a position corresponding to the heat-conducting plane portion 253 on the heat-conducting plate 25. When the pot body 20 is placed on the base 11, the temperature measuring device 14 passes through the second avoiding hole to contact with the bottom of the inner pot 23 (i.e., the inner pot plane portion 233). Therefore, the temperature measuring device 14 directly senses the temperature of the inner pot 23, and the temperature measuring result is more accurate.

With continued reference to fig. 3, generally, the thermally conductive plate 25 is provided with a larger area so as to be in more contact with the inner pot 23. However, due to size and specification constraints, the heating device 13 tends to be small in size and not compatible with the size of the heat-conducting plate 25. Preferably, the heat conductive plate 25 may be provided to have a non-uniform thickness. Specifically, the heat conductive plate 25 as a whole may include a first portion located within the projection range of the heating device 13 and a second portion located outside the projection range of the heating device 13 as viewed in the up-down direction. Wherein the first part is in direct thermal contact with the heating means 13 and the second part is indirectly in thermal contact with the heating means 13 via the first part. Preferably, the thickness of the first portion is greater than the thickness of the second portion. Thereby, heat can be more uniformly transferred to the inner pot 23 through the heat conductive plate 25.

It is understood that in other embodiments, the cooking device according to the present invention may not have the storage bin and the corresponding material feeding assembly, but may add the material in other manners, such as manual addition.
