Description

TECHNICAL FIELD

[0001] The utility model relates to a voltage pressure cooker with switchable pressure relief mode. BACKGROUND

[0002] The pressure type electric rice cooker, or the pressure cooker with the function of the electric rice cooker, is a common household appliance. In the past, there was a patent number CN202221125149.9 with the name of a cooking appliance capable of switching the functions of the electric pressure cooker and the electric rice cooker. This kind of cooking appliance can lift or lower the exhaust valve block by pushing the lever with the knob, that is, the function of the electric pressure cooker or the electric rice cooker can be switched by turning the handle. The working mode of the traditional cooking appliance depends on whether the exhaust valve block is closed. In order to solve the problem of how to switch the working mode, the inventor previously invented a pressure cooker structure for switching the switchable cooking mode. This structure can lift the exhaust valve block by turning the knob and pressing one end of the rocker plate, so that the other end of the rocker plate is lifted. At the same time, the sliding member is driven to move by the knob, and a proximity sensor is provided on the pressure cooker to sense the approach or distance of the sliding member. In this way, the signal can be collected after the knob is operated and transmitted to the internal processor of the pressure cooker, so that the operator's operation can be identified in time, and the working mode of the pressure cooker can be adjusted. However, the pressure cooker will make the sliding member approach or move away from the proximity sensor as long as the knob is turned, which makes the proximity sensor too sensitive to the position of the sliding member, making it difficult to accurately control and the control gear is single.

[0003] The utility model is just based on the above-mentioned deficiencies. UTILITY MODEL CONTENT

The structure of the electric pressure cooker and the induction structure B can refer to the patent No. CN202323621288.8, a pressure cooker pressure relief structure with switchable cooking mode.

[0027] As shown in the figure, Figure 3 and Figure 4 As a preferred embodiment of the induction structure B, the induction structure B comprises an inductive sensor 11 arranged on the pot body 1 and a sensing member 251 arranged on the swing member 25, the middle part of the swing member 25 is rotationally connected to the pot cover 2, the swing member 25 has a first branch arm extending outward from the middle part, and the sensing member 251 is arranged on the first branch arm 252. The inductive sensor 11 can be a general photoelectric sensor, a capacitive sensor, a magnetic sensor, an ultrasonic sensor, an electric inductive sensor, etc., as long as it can sense the approach or distance of the sensing member 251. In this embodiment, the inductive sensor 11, i.e. the proximity sensor, can be an electric inductive sensor, and the sensing member 251 can be a general steel block or iron block or other metal block. Compared with the proximity sensor such as photoelectric sensor, capacitive sensor, magnetic sensor, ultrasonic sensor, etc., the electric inductive sensor has better penetration and can detect the metal block through a thicker wall.

[0028] As shown in the figure, Figure 5 and Figure 6As shown, as a preferred embodiment of linkage structure A, linkage structure A includes a limiting groove 230 provided on the dial 23 and a limiting post 253 provided on the swing member 25. The swing member 25 has a second arm 254 extending outward from the middle. The limiting post 253 is provided on the second arm 254 and extends into the limiting groove 230. The limiting groove 230 has an initial station 2301, a first transition station 2302, a terminal station 2303, and a second transition station 2304 in sequence along the groove wall. The groove wall of the limiting groove 230 includes a first arc segment 232 from the initial station 2301 to the first transition station 2302, a first inclined segment 233 from the first transition station 2302 to the terminal station 2303, a second arc segment 234 from the terminal station 2303 to the second transition station 2304, and a second inclined segment 235 from the second transition station 2304 to the initial station 2301. The first arc segment 232 and the second arc segment 234 are concentric with the rotation axis P of the dial 23. Figure 7 As shown, in the initial state, the limiting post 253 is located at the initial station 2301, and the sensing member 251 is located at the position corresponding to the inductive sensor 11. The top pressing part 231 is offset from the end of the flap member 24, and the exhaust valve block 21 is in the lowered position. The control module in the electric pressure cooker acquires signals through the inductive sensor 11 to realize the pressure increasing mode. After the dial 23 is rotated by a preset angle, the limiting post 253 moves along the first arc segment 232 to the first transition station 2302. The preset angle is determined according to the positions of the two ends of the first arc segment 232. Since the axis P of the first arc segment 232 is consistent, the position of the swing member 25 does not change. The dial 23 is rotated to the position where the top pressing part 231 abuts against the end of the flap member 24. The exhaust valve block 21 remains in the lowered position, and the electric pressure cooker remains in the original working state. After the dial 23 is rotated by a preset angle again, the limiting post 253 moves along the first inclined segment 233 to the terminal station 2303. Since the first inclined segment 233 is inclined from the position away from the axis P to the position close to the axis P, the first inclined segment 233 pushes the swing member 25 to rotate in the process, thereby making the sensing member 251 move away from the position corresponding to the inductive sensor 11. At the same time, the top pressing part 231 presses down one end of the flap member 24, thereby making the other end of the flap member 24 lift the exhaust valve block 21 upward. The exhaust valve block 21 is in the raised position. The control module in the electric pressure cooker acquires signals through the inductive sensor 11 to realize the pressure relief mode. After the dial 23 is rotated by a preset angle again, the limiting post 253 returns to the initial station 2301 along the second arc segment 234. The dial 23 is rotated to the position where the top pressing part 231 abuts against the end of the flap member 24. The exhaust valve block 21 returns to the lowered position, thereby resetting to the initial working state. The above structure realizes the effect of accurately controlling the working mode of the electric pressure cooker in multiple gears.

[0029] As a preferred embodiment, as shown in Figures 4 to 7 The elastic part 237 is provided with a plurality of stop recesses 236, and the pot cover 2 is provided with a clamping protrusion 12 capable of being clamped into each recess during the rotation of the dial 23. The elastic part 237 is provided with three stop recesses 236, which are an initial stop groove 236a, a transition stop groove 236b, and a terminal stop groove 236c arranged in sequence. When the limiting column 253 reaches the initial station 2301, the top pressing part 231 is clamped into the initial stop groove 236a. When the limiting column 253 reaches the first transition station 2302 or the second transition station 2304, the top pressing part 231 is clamped into the transition stop groove 236b. When the limiting column 253 reaches the terminal station 2303, the top pressing part 231 is clamped into the terminal stop groove 236c. Thus, the twist knob 22 can obtain a feedback of damping change at each stop position, so that when the clamping protrusion 12 is clamped into the stop recess 236 during the rotation of the twist knob 22, the damping is smaller, and the user can perceive that the twist knob 22 has reached each stop position, thereby achieving accurate control between each stop position.

[0030] As a preferred embodiment, as shown in Figures 1 to 3 In order to facilitate the user to intuitively perceive the position of the twist knob 22, the twist knob 22 is further provided with a stop position mark 221 for the user to observe.

[0031] As a preferred embodiment, as shown in Figure 3 The pot cover 2 is provided with a mounting bracket 26, the mounting bracket 26 is provided with a sliding cavity 260 for accommodating the swing member 25, the swing member 25 is provided with a mounting hole 250 in the middle, and the sliding cavity 260 is provided with a mounting column 261 for penetrating through the mounting hole 250, so that the swing member 25 can be rotatably connected to the mounting bracket 26.

[0032] As a preferred embodiment, as shown in Figures 1 to 5 The pot cover 2 is connected with a button member 27 capable of sliding up and down relative thereto, the bottom of the button member 27 is provided with a top pressing rod 271, the bottom end of the top pressing rod 271 penetrates through the twist knob 22 and the dial 23 and reaches above the end of the rocker member 24, and the pot cover 2 is provided with an elastic member 28 capable of pushing the button member 27 to reset upward, so that the button member 27 can be automatically reset after being pressed. Thus, no matter what working state the electric pressure cooker is in, the user can open the exhaust valve block 21 by pressing the button member 27, balance the pressure of the pressure cooker with the air pressure outside, and finally facilitate the user to open the pot cover in this mode. In addition, in an emergency, the user can also quickly operate, thereby improving the safety of the product.

[0033] The above only is the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described too much here. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
