[0030] The following refers to Figures 1-8 Describe a temperature measuring structure of a cooking appliance according to some embodiments of the present application.
[0031] The present utility model provides a temperature measuring structure of a cooking appliance through the following technical solutions, including a pot body 1 and a lid body 2. Among them, the pot body 1 is used to hold the food to be cooked. The top of the pot body 1 has an opening 3, and the food is put into or taken out of the pot body 1 through the opening 3. A limiting structure is provided between the lid body 2 and the pot body 1. The limiting structure includes two mutually cooperating first limiting structures and second limiting structures. When the lid body 2 is closed on the opening 1, the first limiting structure and the second limiting structure cooperate to reduce the displacement of the lid body 2.
[0032] A temperature measuring element 4 extending towards the pot body 1 is provided inside the lid body 2. A first contact 5 is provided at the edge of the lid body 2, and a second contact 6 corresponding to the first contact 5 is provided at the edge of the opening 3. Among them, the first contact 5 is electrically connected to the temperature measuring element 4, and the second contact 6 is electrically connected to the control circuit of the cooking appliance. When the lid body 2 is closed on the pot body 1, the first contact 5 and the second contact 6 are pressed and connected, and the temperature measuring signal of the temperature measuring element 4 is transmitted to the control circuit of the cooking appliance through the first contact 5 and the second contact 6.
[0033] In Embodiment 1 of the present technical solution, the first limiting structure includes a first boss 12, and the second limiting structure includes a first notch 13. One of the first boss 12 and the first notch 13 is arranged on the pot body 1, and the other is arranged on the lid body 2. When the lid body 2 is closed on the opening 3, the first boss 12 is inserted into the first notch 13, and the outer wall of the first boss 12 is in abutting fit with the inner wall of the first notch 13 to prevent the lid body 2 from moving around.
[0034] Specifically, the first boss 12 is arranged on the pot body 1, the second contact 6 is arranged on the first boss 12, the first notch 13 is arranged on the lid body 2, and the first contact 5 is arranged in the first notch 13. When the lid body 2 is closed on the opening 3, the first contact 5 presses against the second contact 6 to electrically connect the temperature measuring element 4 to the control system of the cooking appliance; and the cooperation between the first boss 12 and the first notch prevents the lid body 2 from moving around and also keeps the first contact 5 and the second contact 6 in stable contact.
[0035] In Embodiment 2 of the present technical solution, the lid body 2 has a locked position and an unlocked position relative to the pot body 1, and the lid body 2 can be switched between the locked position and the unlocked position by rotating along its central axis. When the lid body 2 rotates from the unlocked position to the locked position and at the end of the rotation stroke of the lid body 2, the first limiting structure and the second limiting structure are in tangential fit. Since the first limiting structure and the second limiting structure are in cooperation at the end of the rotation stroke of the lid body 2, the first limiting structure and the second limiting structure can be designed to be more closely matched, thereby further reducing the amount of movement of the lid body 2 and enabling the first contact 5 and the second contact 6 to better maintain stable contact.
[0036] In the technical solution of Embodiment 2, the first limiting structure includes a card slot 7, and the second limiting structure includes a rib 8. One of the card slot 7 and the rib 8 is arranged on the pot body 1, and the other is arranged on the lid body 2. When the lid body 2 rotates from the unlocked position to the locked position, the rib 8 is inserted into the card slot 7, and the outer wall of the rib 7 is in abutting fit with the inner wall of the card slot 8 to prevent the lid body 2 from moving around.
[0037] Specifically, the card slot 7 is arranged on the pot body 1, the rib 8 is arranged on the lid body 2, the rib 8 extends in the horizontal direction, and the card slot 7 has an opening facing the direction of the rib 8. When the lid body 2 is rotated from the unlocked position to the locked position, the rib 8 is inserted into the card slot 7, thereby restricting the movement of the lid body 2.
[0038] In the technical solution of Embodiment 2, a second boss 9 is provided at the position of the pot body 1 where the card slot 7 is located, the second contact 6 is arranged on the second boss 9, a second notch 10 for the movement of the second boss 9 is provided at the position of the lid body 2 where the rib 8 is located, and the first contact 5 is arranged in the second notch 10.
[0039] In the above technical solution, an elastic element 11 is connected to the bottom of the second contact 6. When the cover body 2 is closed on the opening 3 and the first contact 5 presses against the second contact 6, the second contact 6 remains in contact with the first contact 5 under the action of the elastic element 11.
[0040] Therefore, through the combined action of the limiting structure and the elastic element 11, when the cover body 2 is closed on the opening 3, the first contact 5 and the second contact 6 maintain stable and sufficient contact in both the horizontal and vertical directions, so as to continuously and completely transmit the signal of the temperature measuring element 4 to the control circuit, achieving the same transmission effect as that of connecting with a wire.
[0041] In addition, in order to overcome the top thrust of the gas in the pot body 1 on the cover body 2 when the cooking appliance is in use, it can be achieved by arranging a counterweight 14 in the cover body 2 to increase the self-weight of the cover body 2.
[0042] Preferably, the cooking appliance in this embodiment is an electric rice cooker.
[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
