[0033] The embodiment relates to a rice processing cooking device, which can realize rice steaming function in cooperation with steam boiler, and has the advantages of uniform heating effect and high processing efficiency.

[0034] Overall structure, refer to Figure 1 and Figure 2 The rice processing cooking device of the embodiment comprises an outer box body 1, an inner box body 2, a gas guide pipe 3, a box cover 4 and a tray 5. The outer box body 1 can be a hollow rectangular box body with an open top. The outer box body 1 is provided with a heat insulation layer. The heat insulation layer can be a sleeve made of polymer material or a coating with heat insulation property. The inner box body 2 is installed on the inner side of the outer box body 1 and has a certain gap with the outer box body 1. A plurality of heating holes 201 are formed in the bottom of the inner box body 2. The heating holes 201 can be a plurality of waist-shaped through holes uniformly distributed along the length direction of the inner box body 2. The gas guide pipe 3 is arranged at the top of the outer box body 1.

The box cover 4 is installed on the outer box body 1 and forms a closed space with the outer box body 1 for the inner box body 2. The tray 5 is installed on the inner box body 2.

[0035] Refer toFigure 1 The number of the air guide pipes 3 can be two. The two air guide pipes 3 are symmetrically distributed about the geometric center of the outer box body 1. By increasing the number of the air guide pipes 3 and using two air guide pipes 3 to simultaneously ventilate the inside of the outer box body 1, convection can be formed at the top area of the gap between the outer box body 1 and the inner box body 2, which is beneficial to avoid the accumulation of steam at the top of the outer box body 1, so that the steam can quickly reach the bottom of the inner box body 2 after being introduced into the outer box body 1, thereby further improving the uniformity of the rice cooking and heating effect. The edge of the end of the air guide pipe 3 away from the outer box body 1 is treated with an inverted bevel.

[0036] As arranged above, the outer box body 1 plays a supporting and limiting role on other part structures, and the air guide pipe 3 can transmit the steam generated by the steam boiler to the top of the gap between the inner box body 2 and the outer box body 1. The heating hole 201 arranged at the bottom of the inner box body 2 plays a role in conducting steam, so that the steam can heat the rice in the tray 5 from bottom to top. The tray 5 can serve as a rice container, and the box cover 4 can cooperate with the outer box body 1 to form a heat-insulated sealed space to achieve rapid heating and cooking. Compared with the heating method of the electric heating steamer in the prior art, the steam in the present application can flow from bottom to top, ensuring the maturity of rice at different heights and improving the uniformity of the heating effect. The direct steam heating method has an advantage in speed over the method of generating steam by heating and cooking rice. By treating the outer edge of the air guide pipe 3 with an inverted bevel, the air guide pipe 3 can be easily connected with the hose of the steam boiler outlet, improving the convenience of use.

[0037] With reference to Figure 1 The side edge of the outer box body 1 close to the box cover 4 is provided with a sealing strip 101 along the circumference.

By adding a sealing strip 101 between the outer box body 1 and the sealing cover, the sealing property of the cooperation part of the box cover 4 and the outer box body 1 can be further improved, the steam dissipation and heat loss can be reduced, and the heating efficiency can be further improved. By arranging supporting legs 102 at the bottom of the outer box body 1, the contact area of the outer box body 1 and the supporting interface can be reduced without significantly affecting the overall stability, and the heat loss can be reduced.

[0038] With reference to Figure 1 and Figure 2, the number of the trays 5 can be set as two. The two trays 5 are slidably arranged inside the inner box 2 along the horizontal direction and are parallelly distributed above and below each other. The top edge of the tray 5 extends outward to form an extension 501. The extension 501 is provided with a plurality of through holes. By setting the tray 5 as two, the efficiency and yield of rice cooking can be improved. By forming a sliding connection structure between the tray 5 and the inner box 2, the tray 5 can be conveniently taken and placed, and the use convenience is improved. By forming the extension 501 with the through holes on the top edge of the tray 5, on the one hand, the stability of the tray 5 inside the inner box 2 can be improved, and on the other hand, the influence of the tray 5 on the upward flow of steam can be reduced, and the uniformity of the heating effect is ensured.

[0039] With reference to Figure 1 , the top of the outer box 1 is provided with a pressure relief valve 6. The pressure relief valve 6 is in one-way communication with the inside of the outer box 1. When the pressure inside the outer box 1 reaches the preset threshold of the pressure relief valve 6, the valve core of the pressure relief valve 6 will be pushed open, so that the inside of the outer box 1 is in one-way communication with the outside, the steam is released to reduce the pressure, and the safety of the whole device is ensured.
