Description

Technical Field

[0001] This utility model relates to the field of electric slow cooker technology, and in particular to an electric slow cooker equipped with a temperature sensing device. Background Technology

[0002] Currently, most electric slow cookers on the market use time control technology as their core control method. Its advantages lie in its simple and intuitive operation; users can preset the cooking time without real-time monitoring, meeting basic timer needs. Furthermore, the technology is mature, low-cost, and easily mass-produced, ensuring the product's cost-effectiveness.

[0003] While this technology offers these advantages, it also suffers from significant functional limitations. For instance, its core limitation lies in its ability to only preset a fixed cooking time, unable to dynamically adjust based on the actual cooking conditions. When the power setting is too high or the cooking time is too long, the broth inside the stew pot will boil violently, easily leading to overflow. This not only causes nutrient loss and increases the burden of cleaning the countertop, but the overflowing broth may also seep into the device and corrode the circuitry. Conversely, if the power is too low and the cooking time is insufficient while there is too much broth in the stew pot, the food may not be cooked through. More seriously, it lacks the ability to handle changes in water volume. If the initial water level is insufficient, or if the food itself is highly absorbent and quickly loses moisture, the timer system will continue heating according to the preset time, easily causing dry burning. Dry burning not only chars and spoils the food, but the high temperature can also directly damage the glaze or material of the stew pot, significantly shortening its lifespan.

[0004] Therefore, both the risk of electrical malfunctions caused by overflowing soup and the potential for high temperatures due to dry burning pose serious threats to safety. They also significantly reduce the lifespan of the electric slow cooker.

[0005] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0006] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, one objective of the present invention is to provide an electric slow cooker equipped with a temperature sensing device, which can autonomously control the temperature during cooking, making it safer for users.

[0007] The above objective is achieved through the following technical solution:

[0008] An electric slow cooker equipped with a temperature sensing device includes an outer shell assembly, a stewing pot, a stewing pot lid, an operation panel, a heating device, a temperature sensing device, and a control system. A heating cavity with an open top is formed within the outer shell assembly. The heating device is disposed around the outer periphery of the heating cavity.

The temperature sensing device is disposed inside the second convex ring. When the stewing pot is placed on the inner shell, the first convex ring abuts against the first step, thereby forming a temperature measuring space between the inner side of the first convex ring, the bottom wall of the heating cavity, and the bottom of the stewing pot.

The limiting cover has a limiting post at a matching position. The limiting post has a limiting blind hole in the middle. The limiting post is inserted into the limiting insertion hole from top to bottom.

Detailed Implementation

[0028] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0029] like Figure 1-6 As shown, this embodiment provides an electric slow cooker equipped with a temperature sensing device, including an outer shell assembly 1, a stewing pot 2, a stewing pot lid 3, an operation panel 4, a heating device 5, a temperature sensing device 6, and a control system 8. A heating cavity 11 with an open top is formed within the outer shell assembly 1. The heating device 5 is disposed around the outer periphery of the heating cavity 11. The stewing pot 2 is detachably disposed within the heating cavity 11. The temperature sensing device 6 is fixedly disposed at the bottom of the stewing pot 2. A conductive member 7 is disposed on the bottom of the heating cavity 11. The top end of the conductive member 7 contacts the temperature sensing device 6, and the bottom end is connected to the control system 8. The stewing pot lid 3 is disposed on the top of the stewing pot 2. The operation panel 4 and the control system 8 are disposed on the outer shell assembly 1, and the control system 8 is electrically connected to the operation panel 4, the heating device 5, and the conductive member 7, respectively. The conductive member 7 and the temperature sensing device 6 allow the control system 8 to promptly understand the temperature inside the stewing pot 2, thereby intelligently adjusting the heating time and heating power.

[0030] This invention proposes an electric slow cooker equipped with a temperature sensing device, which can automatically control the temperature during cooking, preventing the slow cooker from dry-burning or continuously overflowing liquid, thus making it safer for users. At the same time, because the slow cooker remains within a suitable temperature range during use, avoiding dry-burning and liquid overflow, it also extends the lifespan of the slow cooker.

[0031] In this embodiment, the control system receives the temperature signal fed back by the temperature sensing device 6, adjusts the temperature signal, and then controls the operation of the heating device 5 accordingly, thereby further improving the temperature control accuracy of the electric slow cooker.

[0032] Specifically, the outer shell assembly 1 includes an outer shell 12, a base 13, and an inner shell 14. The inner shell 14 is fixedly disposed inside the outer shell 12, and the heating cavity 11 is formed inside the inner shell 14. The heating device 5 is wrapped around the outer side of the inner shell 14, and the base 13 is fixedly disposed on the bottom of the outer shell 12.

[0033] A first step 141 is provided at the bottom of the inner shell 14 near its outer edge. A first convex ring 21 and a second convex ring 22 are provided at the bottom of the stewing pot 2, with the circumference of the first convex ring 21 being larger than that of the second convex ring 22. The temperature sensing device 6 is disposed inside the second convex ring 22. When the stewing pot 2 is placed on the inner shell 14, the first convex ring 21 abuts against the first step 141, thereby forming a temperature measuring space between the inner side of the first convex ring 21, the bottom wall of the heating cavity 11, and the bottom of the stewing pot 2. The abutment between the first convex ring 21 and the first step 141 can isolate the temperature of the side wall of the inner shell 14, making the temperature sensing device 6 more accurate in detecting the temperature of the bottom of the stewing pot 2 within the temperature measuring space, and avoiding the influence of the side wall of the inner shell 14 and the heating device 5 on the temperature sensing device 6.

[0034] Furthermore, the temperature sensing device 6 includes a temperature sensing plate 61, a temperature detection element 62, and a mounting base 63. The temperature detection element 62 is disposed within the mounting base 63, and the temperature sensing plate 61 is on the mounting base 63, sealing the temperature detection element 62 within the mounting base 63. The temperature sensing plate 61 is in contact with the bottom of the stewing pot 2. The arrangement of the temperature sensing plate 61 and the mounting base 63 increases the contact area between the temperature sensing device 6 and the bottom of the stewing pot 2, making the temperature sensing more accurate; it also protects the temperature detection element 62, preventing it from being damaged during daily use.

[0035] Specifically, the temperature sensing device 6 also includes a limiting seat 64, a limiting cover 65, and a sealing ring 9. The limiting seat 64, the limiting cover 65, and the sealing ring 9 are installed at the bottom of the inner housing 14. The limiting seat 64 has a limiting insertion hole 641 in the middle, and the limiting cover 65 has a corresponding limiting post 651. The limiting post 651 has a limiting blind hole 652 in the middle. The limiting post 651 is inserted into the limiting insertion hole 641 from top to bottom, and a screw is inserted into the limiting blind hole 652 from bottom to top, thereby fixing the base 13, the limiting seat 64, and the limiting cover 65 together. The limiting seat 64 and the limiting cover 65 allow the temperature sensing device 6 to be firmly fixed to the base 13. The sealing ring 9 protects the space between the limiting seat 64 and the limiting cover 65.

[0036] The limiting seat 64 also includes a conductive component seat 642. A conductive component hole 653 is provided at a position on the limiting cover 65 that is compatible with the conductive component 7. A reinforcing part 643 is provided on the conductive component seat 642. Several conductive components 7 pass sequentially through the reinforcing part 643 and the conductive component hole 653 on the conductive component seat 642. The conductive component seat 642, the reinforcing part 643, and the conductive component hole 653 all ensure that the conductive component 7 is securely fixed on the limiting seat 64. In particular, when the stewing pot 2 is placed into the heating chamber 11, this design prevents the conductive component 7 from shifting due to the weight of the stewing pot 2 and the food.

[0037] Furthermore, a connecting piece 10 is provided at the bottom of the mounting base 63, and the top ends of several conductive members 7 are in electrical contact with two of the connecting pieces 10. The connecting piece 10 can transmit the detected temperature information to the conductive members 7, which in turn transmit it to the control system 8. The several conductive members 7 are distributed in different positions, which can improve the reliability of the electrical contact between the temperature sensing device 6 and the conductive members 7.

[0038] In particular, the conductive component 7 is made of a resiliently expandable metal. When the stewing pot 2 is placed into the heating chamber 11, the weight of the stewing pot 2 will press against the conductive component 7. The fact that the conductive component 7 is made of a resiliently expandable metal facilitates the connection between the temperature sensing device 6 and the conductive component 7.

[0039] Furthermore, the stewing pot 2 is provided with an upper baffle 23 and a lower baffle 24 on its upper side. The lower baffle 24 extends downward from the stewing pot 2 to the outer side of the top of the outer shell 12, and the upper baffle 23 extends upward from the stewing pot 2 to cover the edge of the stewing pot lid 3. The upper baffle 23 not only limits the position of the stewing pot lid 3, but also reduces liquid overflow when the food boils. The lower baffle 24, when liquid does overflow, prevents liquid from flowing to the connection between the outer shell 12 and the inner shell 14, thus protecting the internal structure of the outer shell assembly 1.

[0040] Furthermore, the outer casing 12 is provided with a window 121, and the operation panel 4 and the control system 8 are disposed on the window 121. This allows users to perform personalized operations through the operation panel 4.

[0041] Preferably, the stew pot lid 3 is provided with a vent 31 and a handle 32. The vent 31 facilitates the venting of the stew pot 2 and prevents boiling liquid from overflowing; the handle 32 makes it easy for the user to lift the stew pot lid 3.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
