Through the first-stage heat insulation component 3, the second-stage heat insulation component 4 and the heat insulation gap 100, the present utility model can block the heat generated in the slow cooker main body 1, so that the heat will not be directly transferred to the display control module 2, achieving the purpose of double-layer heat insulation protection for the display control module 2, making the service life of the display control module 2 higher, ensuring its operation sensitivity, and not feeling hot when touched, with a better use experience.

[0024] In order to achieve the purpose of separating the first-stage heat insulation component 3 and the second-stage heat insulation component 4 through a simpler structure, as Figure 4 shown, a separating block 101 is also provided between the first-stage heat insulation component 3 and the second-stage heat insulation component 4 to separate the two and keep them in a separated state. Such a structure is very simple, conducive to production and manufacturing, and can keep the first-stage heat insulation component 3 and the second-stage heat insulation component 4 always separated.

[0025] In order to achieve quick positioning and facilitate quick assembly, as Figure 4 shown, a positioning groove 102 for sleeving the separating block 101 is provided on the first-stage heat insulation component 3 or the second-stage heat insulation component 4. Through the setting of the positioning groove 102, when the first-stage heat insulation component 3 and the second-stage heat insulation component 4 are stacked together, it can play a role in quick positioning, so that the first-stage heat insulation component 3 and the second-stage heat insulation component 4 can be quickly and accurately assembled together. Specifically, the separating block 101 can be provided on the first-stage heat insulation component 3 or on the second-stage heat insulation component 4. Preferably, the separating block 101 is provided on the second-stage heat insulation component 4, and the positioning groove 102 is provided on the first-stage heat insulation component 3.

[0026] In order to further improve the structure of the first-stage heat insulation component 3, make its structure simple, scientific and reasonable, and easy to produce and manufacture, as Figure 3 and Figure 4As shown, the first-stage heat insulation component 3 is composed of a first bottom plate portion 31 and a first enclosing portion 32 provided on the peripheral side edges of the first bottom plate portion 31. A nested groove 33 is also formed by enclosing between the first enclosing portion 32 and the first bottom plate portion 31. The second-stage heat insulation component 4 is embedded in the nested groove 33; the heat insulation gap 100 is provided between the second-stage heat insulation component 4 and the nested groove 33. Through the setting of the first bottom plate portion 31, it can play a role in blocking heat. Through the settings of the first enclosing portion 32 and the nested groove 33, it can play a role in enclosing and protecting the second-stage heat insulation component 4, making the second-stage heat insulation component 4 not easily damaged by bumps, ensuring that the first-stage heat insulation component 3 and the second-stage heat insulation component 4 are not easily loosened, and thus ensuring the stability of the connection between the slow cooking machine main body 1 and the display control module 2.

[0027] In order to further improve the structure of the second-stage heat insulation component 4, make its structure simple, scientific and reasonable, and easy to manufacture, as Figure 3 shown in Figure 4 As shown, the second-stage heat insulation component 4 is composed of a second bottom plate portion 41 and a second enclosing portion 42 provided on the peripheral side edges of the second bottom plate portion 41. A heat dissipation cavity 44 with an upper opening 43 is also formed by enclosing between the second enclosing portion 42 and the second bottom plate portion 41. The display control module 2 is covered on the opening 43; heat dissipation through holes 45 penetrating through to the heat insulation gap 100 are also provided on the cavity wall or cavity bottom of the heat dissipation cavity 44. Through the setting of the second bottom plate portion 41, it can play a role in blocking heat. Through the settings of the heat dissipation cavity 44 and the heat dissipation through holes 45, air can flow into and out of the heat dissipation cavity 44, which is beneficial to the heat dissipation of the display control module 2, and the heat dissipation cavity 44 can allow more air to enter its interior, so that the heat dissipation effect can be better.

By providing the inlet 123 and the outlet 124, it is convenient for the water to flow into the casing 12 through the stirring device 14, be heated, and then flow out, so that the water in the entire container can be fully heated. By making the air inlet 122 located above the air outlet 121, the hot air located at the upper end of the casing 12 can also be sucked away and discharged, so that the hot air is not likely to accumulate at the upper end of the casing 12, ensuring that the display control module 2 is not easily affected by high temperature.

[0031] In the actual application process, a wire passing hole 34 is further provided on the first-stage heat insulation component 3, and the wire passing hole 34 respectively connects the heat dissipation through hole 45 with the inside of the casing 12. This can not only allow the wires to pass through and be hidden, but also, when the heat dissipation fan device 16 sucks air from the upper end of the casing 12, the air in the heat insulation gap 100 and the heat dissipation cavity 44 can be sucked into the heat dissipation fan device 16 through the wire passing hole 34 and discharged, so as to improve the heat dissipation and insulation effect. Specifically, a wind guiding convex part 35 penetrating through the heat dissipation through hole 45 is further provided on the first-stage heat insulation component 3, and the wire passing hole 34 is arranged on the wind guiding convex part 35. Through the arrangement of the wind guiding convex part 35, when sucking air, the air in the heat insulation gap 100 can flow into the heat dissipation cavity 44, and then flow into the casing 12 through the wire passing hole 34 to form a heat dissipation air duct, further improving the heat dissipation effect of the display control module 2.

Its specific structure and working principle will not be elaborated here.

[0034] To further improve the structure of the casing 12, as Figure 5 shown, the casing 12 is composed of an upper casing 125 and a lower casing 126 that are butted together, and a mounting seat 127 provided in the upper casing 125. The stirring device 14, the heating device 15, the heat dissipation fan device 16, the water level probe 17, the temperature probe 18, and the dry burning prevention probe 19 are respectively installed on the mounting seat 127. Specifically, the air outlet 121 is provided on the upper casing 125, the air inlet 122 is provided on the first-stage heat insulation component 3, and the water inlet 123 and the water outlet 124 are respectively provided on the lower casing 126.

In the actual application process, the upper casing 125 is made of plastic material, and the lower casing 126 is made of metal material, so that the structural strength and heat resistance are better.

[0035] In the actual application process, the display control module 2 is a control panel structure with a color display screen and control buttons. So that the temperature, time, and the working states of various electrical components can be displayed on the display control module 2. And the function menus of all electrical components are displayed on the display control module 2, so that one-key startup can be realized, and the operation is convenient and fast.
