[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figures 1 to 8 As shown, a multifunctional instant electric pressure cooker includes a pot body 1 and a pot cover 2, wherein the pot body 1 is provided with a heating plate 3 and an inner pot 4 placed on the heating plate 3 and heated, the pot cover 2 includes an outer cover 5 and an inner cover assembly, the inner cover assembly is assembled and connected below the outer cover 5, the inner cover assembly cooperates with the opening of the inner pot 4, and a cooking cavity 401 is defined between the two, a cooling groove 701 is recessed on the top surface of the inner cover assembly, and a first water outlet 501 and a second water outlet 502 are respectively connected to the cooling groove 701 and the cooking cavity 401; a water supply device 8 is provided on the pot body 1 or the pot cover 2, and the water outlet end of the water supply device 8 is connected to an electrically controlled three-way valve 9, one water outlet 91 of the electrically controlled three-way valve 9 is connected to the first water outlet 501, and the other water outlet 92 is connected to the second water outlet 502, and the water supply device 8 is controlled by the electrically controlled three-way valve 9 to selectively connect to the cooling groove 701 or the cooking cavity 401.

[0033] This electric pressure cooker is divided into two water outlets through an electric-controlled three-way valve 9, which can simplify the internal structure of the pot cover, reduce production costs, and change the water supply direction according to different functional needs of the electric pressure cooker to achieve the function of cooling and quickly opening the cover or the function of instant steam generation.

[0034] The inner cover assembly includes an inner cover 6, which is sealed with the opening of the inner pot 4 and defines a cooking cavity 401; a water receiving groove 601 is concavely provided on the top surface of the inner cover 6, the second water outlet 502 is communicated with the water receiving groove 601, and a water outlet nozzle 61 is provided at the edge of the inner cover 6 to abut or abut against the inner wall of the inner pot 4, and the water outlet nozzle 61 is communicated with the water receiving groove 601;

[0035] This electric pressure cooker generates steam by heating first and then discharging water. When in use, the inner pot 4 is heated by the heating plate 3 to raise the temperature, so that the inner pot 4 is in a high temperature state, and then the water transported to the water receiving tank 601 is discharged through the water outlet 61, so that the water can flow downward along the inner wall surface of the inner pot 4, and immediately form high-temperature and high-pressure steam after touching the bottom of the high-temperature inner pot 4, thereby improving the heating speed of the electric pressure cooker;

[0036] Moreover, the side wall of the inner pot 4 with a certain temperature can preheat the water, which helps to improve the efficiency of the water's instant evaporation, and the water flows downward along the inner wall of the inner pot 4, avoiding the food in the middle and preventing water from dripping on the food and affecting the taste of the food.

[0037] The inner cover assembly also includes a cooling plate cover 7, which is movably assembled between the outer cover 5 and the inner cover 6, and a cooling groove 701 is recessed in the center range thereof, a water unloading gap 702 is provided between the cover edge of the cooling plate cover 7 and the outer cover 5, and an annular water guide groove 101 is provided on the top surface of the pot body 1, and the water guide groove 101 is arranged below the water unloading gap 702.

[0038] After cooking is completed, the electric pressure cooker starts the water supply device 8 to send cold water to the cooling groove 701 of the cooling plate cover 7 to absorb the heat of the cooling plate cover 701. The low-temperature cooling plate cover 7 directly exchanges heat with the high-temperature gas in the pot, takes away the heat and reduces the pressure in the pot, so that the pot cover can be opened quickly.

[0039] After the cooling groove 701 is full of water, or when the lid is opened quickly, the waste water that has absorbed heat (cold water may contact food and cause contamination while absorbing heat) flows out through the water discharge gap 702 and flows into the water guide groove 101 for collection, preventing the waste water from overflowing the outer wall of the electric pressure cooker and causing cleaning difficulties.

[0040] The inner cover 6 is detachably connected to the outer cover 5 via the central assembly column 10, a water inlet channel 1001 is provided in the assembly column 10, and a second water outlet 502 connected to the water inlet channel 1001 is provided at the bottom thereof, a water inlet interface 11 connected to the water inlet channel 1001 is connected to the assembly column 10, and another water outlet 92 of the water supply device 8 is connected to the water inlet interface 11; the inner cover 6 is detachably connected to the assembly column 10, so that the inner cover 6 can be disassembled after cooking is completed, and the upper wall of the inner cover and the lower wall of the cooling plate cover 7 are conveniently cleaned.
