Description

Technical Field

[0001] The utility model belongs to the technical field of kitchenware, and in particular relates to a pressure cooker. Background Art

[0002] A pressure cooker is a kitchen appliance that uses high-pressure steam to cook food. The lid and the pot body form a sealing device, so the pressure cooker will generate high pressure during the cooking process. The pressure cooker can heat the steamed food to above 100°C. The pressure cooker has a unique high temperature and high pressure function, which greatly shortens the cooking time and saves energy, so it is very popular.

[0003] After the pressure cooker is heated, the gas inside the pot expands due to the heat, causing the gas pressure to rise. The lid is pushed by the rising pressure of the gas, causing the lid to be pushed open by the airflow. The lid may be opened when the pressure cooker is under high pressure. At this time, the high-pressure gas in the pot will spray out instantly. In more serious cases, the high-pressure gas will bounce off the lid, endangering the safety of people and property. Under normal circumstances, the airflow in the pressure cooker is sealed, and the internal pressure is increased by generating steam, thereby increasing the cooking temperature and speeding up the cooking of food. However, due to the large airflow in the pressure cooker, if the lid is not sealed well, the steam and heat in the pressure cooker may leak out, causing burns or other accidental injuries.

[0004] At present, most pressure cookers are operated by placing the lid on the mouth of the pot and slowly rotating the lid by hand until the hand can feel the lid rotating easily, and then judging whether the pressure cooker is closed tightly by sound and feeling. This method is complicated to operate, needs to rely on user experience, takes a long time to adjust, and is inconvenient to use. Utility Model Content

[0005] The utility model provides a pressure cooker, aiming to solve the technical problems of the complicated opening and closing structure of the pot cover of the pressure cooker and the complicated operation in the prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A pressure cooker comprises: a pot cover, a pot body, a pot beam and a pot cover lifting assembly, wherein the pot cover is detachably arranged on the pot body, and the pot beam is located above the pot cover;

[0008] The pot cover lifting assembly comprises an operating part and a connecting rod, wherein the operating part is located at the upper end of the connecting rod, the connecting rod is passed through the pot beam, and the operating part drives the pot cover to be lifted or lowered through the connecting rod;

[0009] The pot body is provided with a blocking portion for blocking the pot beam from rising; when the pot cover and the pot body are in a locked state, the pot cover descends to be buckled on the pot body, and both ends of the pot beam are in a state of being blocked by the blocking portion.

[0010] In a preferred solution, a connecting seat is provided on the pot cover, and the lower end of the connecting rod is connected to the connecting seat.

[0011] Based on the above scheme, the connecting seat is used to connect the pot cover to the connecting rod, and the pot cover is driven to engage with or leave the pot body by controlling the lifting and lowering of the connecting rod, and the pot cover is pressurized by the connecting rod.

[0012] In a preferred solution, the connecting seat is a fastening nut, and the connecting rod is inserted into the fastening nut through threads.

[0013] Based on the above scheme, on the one hand, by rotating the connecting rod in the opposite direction, the connecting rod is fixed in the fastening nut through threads to prevent it from loosening and affecting the sealing inside the pot; on the other hand, the fastening nut can effectively keep the position of the connecting rod unchanged by the pre-tightening force on the connecting rod, and it will not move due to vibration or gravity inside the pot or the outside world.

[0014] Preferably, the fastening nut is integrally formed with the pot cover or is fixed to the pot cover by bolts.

[0015] In a preferred embodiment, the operating part is a knob; the lower end of the connecting rod is provided with a thread; the connecting rod is rotatably arranged on the pot beam and the connecting rod and the pot beam are axially fixed, and the lower end of the connecting rod is inserted into the connecting seat through a thread.

[0016] Preferably, the connecting rod includes a threaded portion at the bottom and a limiting portion at the top, the limiting portion is provided with an upper retaining ring, the upper retaining ring abuts against the bottom of the pot beam, and the bottom of the knob abuts against the top of the pot beam.

[0017] Based on the above scheme, the upper retaining ring is used to achieve axial fixation of the connecting rod and the pot beam, and has a simple structure and good stability. When the knob is lifted, the connecting rod drives the pot cover to effectively prevent the pot cover from loosening and falling.

[0018] A preferred solution further includes a limiter for keeping the pot cover and the pot body in a locked state, and the limiter is located in the connecting seat.

[0019] In a preferred solution, the connecting seat is provided with a plug-in hole, the connecting rod is plugged into the connecting hole, and the plug-in hole includes an upper threaded section and a lower smooth section;

[0020] The limiter includes a stopper arranged at the bottom of the connecting rod, the stopper is slidably arranged in the smooth section, and the threaded portion of the connecting rod is connected to the threaded section through a thread; when the stopper abuts against the lower end of the threaded section, the pot cover and the pot body are transformed into a locked state.

[0021] Based on the above scheme, the threaded section serves to limit the rising height of the block. When the connecting rod drives the block to slide upward along the smooth section, the block is blocked by the threaded convex teeth of the threaded section, thereby limiting the rising height of the pot beam driven by the connecting rod.

[0022] When the stopper just abuts against the lower end of the threaded section, the pot cover and the pot body are transformed into a locked state, so that the operating part cannot continue to control the connecting rod to rise when the pot cover and the pot body are in the locked state, and the pressure on the pot cover is increased to avoid deformation of the pot cover, thereby achieving the purpose of protecting the pot cover and extending the service life of the pot cover.

[0023] In a preferred solution, the stopper is a lower stop ring fixedly arranged at the bottom of the connecting rod.

[0024] In a preferred embodiment, the operating part is a knob; a thread is provided on the connecting rod, and the connecting rod passes through the pot beam through the thread; a connecting block is provided at the bottom of the connecting rod, and the connecting block is rotatably arranged in a connecting seat.

[0025] In a preferred solution, the operating part is a cam wrench, the connecting rod is slidably arranged up and down through the pot beam, and the bottom of the connecting rod is arranged on the pot cover.

[0026] Based on the above solution, the cam wrench has the characteristics of simple structure and high stability. The bottom of the connecting rod can be pressed against the pot cover, which is easy to use.

[0027] Preferably, the upper end of the connecting rod is inserted into the lower end of the knob, a threaded hole is provided at the upper end of the connecting rod, the knob and the connecting rod are fixedly connected by bolts, and the bolts are inserted into the threaded hole of the connecting rod from the top of the knob.

[0028] Based on the above scheme, the knob and the connecting rod are fixedly connected by bolts. On the one hand, cooking utensils will inevitably be dirty due to long-term use. If they need to be disassembled and cleaned, it is convenient to disassemble and clean the bolts. On the other hand, the bolts have good stability. The bolts ensure the firmness of the connection between the knob and the connecting rod through their large force-bearing area and large friction coefficient.

[0029] Preferably, the blocking portion is a hook, which includes a connecting portion arranged on the pot body and a bent portion bent toward the center of the pot, and when the pot cover is buckled on the pot body, both ends of the pot beam are located below the bent portion.

[0030] Based on the above scheme, the blocking part plays a reinforcing role, and after the pressure cooker is used, the pressure inside the pot is relatively high. If the user does not operate it properly, the pot cover may pop off. The pot beam is arranged across the pot cover, and the two ends of the pot beam are located below the bent portion of the hook and are blocked by the bent portion, which can effectively prevent the pot cover from being lifted up by the pressure inside the pot and causing danger.

[0031] The beneficial effects of the utility model are:

[0032] 1. The utility model provides a pressure cooker, which adopts the cooperation of a pot beam and a pot cover lifting assembly, and controls the lifting of the connecting rod through the operating part, thereby realizing the fastening or unlocking of the pot cover to the pot body, and controlling the pressurization and pressure relief of the pot cover by the pot beam. When fastening the pot cover, the connecting rod is driven to rise by the operating part, so that the pot beam is quickly lowered and both ends are in a state of being blocked by the blocking part, thereby giving the pot cover downward pressure, so that the pot cover is quickly fastened on the pot body. There is no need to rely on experience, and the pot cover can be fastened by simply placing the pot cover on the pot body. When opening, the pot cover can be unlocked by only using the operating part, which simplifies the opening and closing method of the pressure cooker pot cover, has a simple and reliable structure, is easy to assemble, has high opening and closing efficiency, is low in cost, and effectively improves the convenience of operation.

[0033] 2. In addition, when both ends of the pot beam are blocked by the blocking part, the blocking part will apply a downward force to the pot beam, so that the pot beam always keeps pressurizing the pot cover, thereby preventing the pot beam from loosening during use of the pressure cooker and affecting the sealing inside the pot body.

[0034] 3. The safety of the pressure cooker is improved by providing a blocking part on the pot body to limit the lifting height and installation position of the pot cover. After the pressure cooker is used, the pressure in the pot needs to be released. The blocking part can prevent the pot cover from flying off and causing injuries due to incomplete pressure release caused by user operation errors, thereby improving the safety of the pressure cooker.
