Description

Technical Field

[0001] The invention relates to the field of household appliance manufacturing, in particular to a multi-purpose pressure cooker. Background Art

[0002] In the daily life of residents, pressure cookers are widely used as household kitchen appliances, and are often used to cook rice or other foods. When a pressure cooker is used to cook dry rice, in order to ensure that the rice can be fully soaked and the heat transfer of the contained materials is convenient, more water is generally added when preparing the materials, and the excess water in the pressure cooker is evaporated by high-temperature heating in the later stage of cooking and discharged from the pot body through a preset exhaust valve, so that dry rice with less water can be obtained. The current method of cooking dry rice adopted by the pressure cooker has a lot of water in the high-temperature and sealed pressure cooker inner pot during the cooking and heating cycle, and the temperature of the rice is difficult to obtain an ideal control curve, so the cooked rice cannot obtain the effect of high-temperature baking in terms of taste, and this method also consumes a lot of electricity because it must use a high-temperature evaporation method to discharge excess water vapor. In addition, during the process of cooking rice with a pressure cooker, the high sugar substances infiltrated into the rice soup are harmful to the health of certain patients, and these high sugar substances still remain in the rice in the later stage of cooking. If the excess high sugar rice soup can be filtered and discharged in the later stage of cooking, not only can the excess sugar-containing substances in the rice soup be removed, but also the later cooking time can be reduced, thereby reducing the power consumption. At present, although there is a special pressure cooker with a double-layer inner tank and a soup filter structure on the market that can filter out the excess rice soup during the cooking process of rice, its structural design is complex, resulting in high cost and the cleaning and tidying of its pot body is relatively cumbersome and troublesome, so it is difficult to be popularized and promoted. In short, the current pressure cookers either do not solve the problem of filtering the excess rice soup during the cooking process of rice, or although they can solve the problem, they have the disadvantages of complex structure, inconvenient operation and high manufacturing and use costs. Therefore, the market needs a pressure cooker with a simple structure, convenient use, low manufacturing cost and the ability to filter the excess rice soup during cooking. Summary of the invention

[0003] The purpose of the invention is to provide a multi-purpose pressure cooker to solve the problem of filtering excess rice soup during rice cooking.

[0040] The second embodiment of the present invention is shown in FIG. Figure 7-9 As for 3-5, the structure of this embodiment is similar to that of the first embodiment, and the operation is similar, with the only difference being that in the second embodiment, the dewatering magnet 34 and the dewatering armature 362 are eliminated, and the inner edge of the column tank seat ring 31 and the outer edge of the plunger disk 361 of the plunger shaft 360 are coupled by a large pitch thread to convert the rotational motion of the knob 365 into the up and down motion of the plunger shaft 360.

[0041] In the structures of the above two embodiments, the non-sealing parts in the pot body 1, the pot cover 2, the column pot 3 and the plugging cover 5 are made of aluminum-based alloy materials, the return spring 35 is made of spring steel, the pot body handle 11 and the pot cover handle 24 can be made of metal materials or plastics, all rubber seals are made of high-temperature resistant food-grade rubber, the soup strainer armature 362 is made of magnetic conductive material, and the remaining parts can be standard parts or non-standard customized parts.

[0042] Here’s how to use it:

[0043] When using the first embodiment, refer to Figure 1-6 If you are cooking porridge or rice that does not need to drain the soup, or steaming ingredients, you only need to remove the column pot 3 from the pot cover 2 and replace it with the plug cover 5 and rotate and lock it on the pot cover 2. Then, you only need to put the raw materials (including water) in the pot body 1 and buckle the pot cover 2 and rotate and lock it. Then you can place the pressure cooker on the stove and heat it by manual or automatic control until cooking is completed.

[0044] If you are cooking rice that needs to be drained, just remove the plug cover 5 from the pot cover 2 and replace it with the column pot 3 and rotate and lock it on the pot cover 2, then put rice and water in the pot body 1 in an appropriate proportion and buckle the pot cover 2 and rotate and lock it. Then start the cooking operation, refer to Figure 6 First, manually rotate the knob 365 to the "column cavity closed" position. At this time, the soup draining magnet 34 and the soup draining armature 362 are misaligned, causing the attraction between the two to disappear. Then, the plunger 36 moves downward under the elastic force of the return spring 35 and makes the rubber ring plug 364 block the soup draining hole 373 at the lower end of the soup cup 37. At this time, the A cavity in the pot body 1 and the B cavity in the column tank 3 are isolated. Then use the stove to start heating the pot body 1. When the contents of the pot body 1 are boiled and boiled for a certain period of time, stop heating. Then, the knob 365 is manually rotated to the "column cavity opening" position. At this time, the attraction generated by the alignment of the draining magnet 34 and the draining armature 362 drives the plunger 36 to overcome the elastic force of the return spring 35 and move upward, so that the rubber ring plug 364 is separated from the draining hole 373 at the lower end of the soup cup 37. At this time, the A cavity in the pot body 1 and the B cavity in the column tank 3 are connected, so the rice soup in the A cavity in the pot body 1 is pumped into the B cavity in the column tank 3 under the pressure of high-temperature steam, and a delay period is delayed until the rice soup is completely pumped into the column tank 3. Then, the knob 365 is rotated to the "column cavity closing" position again. At this time, the draining magnet 34 and the draining armature 362 are misaligned again, resulting in the disappearance of the attraction between the two. Therefore, the plunger 36 moves downward under the elastic force of the return spring 35 and causes the rubber ring plug 364 to block the draining hole 373 at the lower end of the soup cup 37 again. At this time, the A cavity in the pot body 1 and the B cavity in the column tank 3 are isolated again and the rice soup is sealed in the cavity of the column tank 3. Then the stove continues to heat the pot body 1 until the rice is cooked, so that the soup draining operation during the rice cooking process can be completed.

[0045] After use, if the column tank 3 needs to be cleaned, the soup cup 37 can be rotated and removed to pull out the plunger 36 downwards and the components of the column tank 3 can be cleaned very conveniently.

[0046] The operation of the second embodiment is shown in FIG. Figure 7-93-5, similar to the operation of the first embodiment, the connection and isolation between the column tank 3 and the pot body 1 are also achieved by changing the blockage and separation of the rubber ring plug 364 on the soup drain hole 373 at the lower end of the soup cup 37 through the up and down movement of the plunger 36. The only difference is that the up and down movement of the plunger 36 of the second embodiment is achieved by converting the rotational movement of the knob 365 into the up and down movement of the plunger shaft 360 through a large pitch thread coupled between the inner edge of the column tank seat ring 31 and the outer edge of the plunger disk 361 of the plunger shaft 360.

[0047] The parts not involved in the present invention are the same as the prior art or are implemented by using the prior art. The above description is only the preferred embodiment of the present invention, and does not limit the present invention in any form.

[0048] Those skilled in the art may make various equivalent changes and improvements based on the above embodiments. All equivalent changes and modifications made within the scope of the claims should fall within the protection scope of the present invention.
