Description

Technical Field

[0001] The utility model relates to the technical field of pressure cookers, in particular to an exhaust and scalding prevention device for pressure cookers. Background Art

[0002] A pressure cooker is also called a pressure cooker or a pressure cooker. It is a kind of kitchen cooker. The pressure cooker uses the physical phenomenon that the boiling point of liquid under high pressure will increase, so that water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the food to above 100℃. In high altitude areas, the use of a pressure cooker can avoid the problem of the boiling point of water being lowered and the food being difficult to cook. Its advantages are time saving and energy saving. When using a pressure cooker, it is necessary to exhaust the air. In order to avoid scalding when exhausting the air, an exhaust anti-scalding device is required.

[0003] Chinese patent number CN210300631U provides a safety exhaust device for a pressure cooker and a pressure cooker.

[0026] See also Figure 1-Figure 4The exhaust structure 200 includes an anti-scalding member 210, an exhaust member 220 and a heat-insulating protective plate 240. The anti-scalding member 210 includes an anti-scalding shell 211. The interior of the anti-scalding shell 211 is provided with a heat-insulating layer 212, a separation plate 213 and an anti-scalding layer 214. The heat-insulating layer 212 has a heat-insulating effect on the exhaust pipe 221. The anti-scalding layer 214 used avoids scalding the anti-scalding member 210 in the exhaust pipe 221, thereby increasing the service life of the anti-scalding member 210. A limiting plate 215 is fixed to the top of the anti-scalding shell 211. The limiting plate 215 can limit the rotating exhaust pipe 221. The exhaust member 220 includes an exhaust pipe 221. The exhaust pipe 221 used rotates in the anti-scalding member 210, which is convenient for adjusting the direction of exhaust. The safe exhaust direction is adjusted according to the direction of exhaust. The exhaust pipe 221 is partially arranged in the anti-scalding shell 211. The anti-scalding shell 211, the exhaust pipe 221 and the heat-insulating protective plate 240 are all Fixed on the top of the pot cover 130, the heat insulation protection plate 240 prevents steam from flowing into the handle 131, thereby preventing scalding when holding the handle 131, a guide plate 222 is fixed at one end of the exhaust pipe 221, a threaded tube 223 is internally threaded at one end of the exhaust pipe 221, and a plurality of exhaust holes 224 are opened on the outer wall of the threaded tube 223, and the plurality of exhaust holes 224 are used to adjust the exhaust amount according to needs, and a guide plate 225 is arranged at one end of the threaded tube 223, and the guide plate 1 222 and the guide plate 225 used guide the steam discharged from the exhaust hole 224 to avoid scalding accidents, and a heat insulation handle 226 is fixed on one side of the guide plate 225, and rotating the heat insulation handle 226 drives the threaded tube 223 to rotate, and the steam is discharged through the exhaust hole 224, and the steam in the exhaust pipe 221 is discharged through the exhaust hole 224, and a gas leaking member 230 is arranged on the top of the exhaust pipe 221.

[0027] The air release member 230 includes an air release pipe 231, which is fixed to the top of the exhaust pipe 221. The top of the air release pipe 231 is threaded with a threaded column 232. When the threaded column 232 rotates, it drives the lifting plate 233 to rise and fall. The lifting plate 233 is fixed to the bottom of the threaded column 232. The lifting plate 233 is lifted and lowered to adjust the pressure of the compression spring 235 on the piston 234, so as to meet the different pressures required by the pressure cooker to adjust the air release amount. The lifting plate 233 is located in the air release pipe 231. A piston 234 is arranged inside the tube 231, and the piston 234 is squeezed by a compression spring 235. When the pressure increases, the piston 234 will gradually move upward to adjust the amount of exhaust from the vent hole 236. A compression spring 235 is fixed between the piston 234 and the lifting plate 233. A plurality of vent holes 236 are arranged on the outer wall of the vent pipe 231. When the vent pipe 231 receives steam pressure, the piston 234 moves upward to connect the vent holes 236 at the bottom to the vent pipe 231 for exhaust.

[0028] Specifically, the working principle of the pressure cooker exhaust and scalding prevention device is as follows: when in use, the pressure cooker is placed at a designated position, and then the inner pot 114 is placed in the outer shell 110, and then the pot cover 130 is covered on the connecting seat 113. When the pressure cooker is in use, the generated steam will enter the exhaust pipe 221, and the piston 234 will be squeezed by the compression spring 235. When the exhaust pipe 231 receives the steam pressure, the piston 234 moves upward, so that the exhaust hole 236 at the bottom is connected to the exhaust pipe 231 for exhaust. When the pressure increases, the piston 234 will gradually move upward to adjust the amount of exhaust from the exhaust hole 236. When the threaded column 232 is rotated, the lifting plate 233 is driven to rise and fall. The lifting plate 233 rises and falls to adjust the pressure of the compression spring 235 on the piston 234, so as to meet the different pressures required by the pressure cooker to adjust the exhaust volume differently. The heat insulation layer 212 used has a heat insulation effect on the exhaust pipe 221. The anti-scalding layer 214 used avoids scalding of the anti-scalding part 210 in the exhaust pipe 221, thereby increasing the service life of the anti-scalding part 210. When exhaust is needed, rotating the heat insulating handle 226 drives the threaded tube 223 to rotate, and the steam is discharged through the exhaust hole 224. The steam in the exhaust pipe 221 is discharged through the exhaust hole 224. The guide plate 1 222 and the guide plate 2 225 used guide the steam discharged from the exhaust hole 224 to avoid scalding accidents. At the same time, multiple exhaust holes 224 are provided to adjust the exhaust amount as needed. The exhaust pipe 221 used rotates in the anti-scalding part 210, which is convenient for adjusting the exhaust direction. The safe exhaust direction is adjusted according to the exhaust direction. At the same time, the limiting plate 215 used can limit the rotating exhaust pipe 221. The heat insulating protective plate 240 used prevents steam from flowing into the handle 131 position, thereby avoiding scalding when holding the handle 131.

[0029] It should be noted that the specific model specifications of the controller 120 and the display screen 121 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0030] The power supply and principle of the controller 120 and the display screen 121 are clear to those skilled in the art and will not be described in detail here.

[0031] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
