DETAILED DESCRIPTION
[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] Double-layer outer pot structure of air heat transfer rice cooker, please refer to Figure 1-2 As shown, it includes: an outer pot 100, an inner pot 200 and a pot cover 300;
[0024] The outer pot 100 comprises: an outer shell 130, a first cover body 110 and a second cover body 120, wherein the second cover body 120 is arranged outside the first cover body 110, and a cavity for accommodating the inner pot 200 is formed in the first cover body 110;
[0025] A first hot air gap 101 is formed between the first cover body 110 and the inner liner 200 , a second hot air gap 102 is formed between the first cover body 110 and the second cover body 120 , and a heat insulation gap 103 is formed between the outer shell 130 and the second cover body 120 .
[0026] like Figure 2 As shown, the first cover body 110 and the second cover body 120 are both installed in the outer shell 130, and the liner 200 can be placed in the cavity of the first cover body 110 and can be taken out from the cavity.
[0027] Furthermore, gaps are formed between the side surfaces of the first cover body 110 and the inner liner 200 , and between the bottom surfaces of the first cover body 110 and the inner liner 200 , so as to form a first hot air gap 101 .
[0028] Furthermore, a protrusion 111 is provided at the bottom of the first cover body 110 protruding into the cavity, and the bottom of the liner 200 is partially supported by the protrusion 111; specifically, the protrusion 111 is provided at the center of the first cover body 110 and is in the shape of a boss. After the liner 200 is placed in the cavity, the bottom of the liner 200 is stably supported by the protrusion 111;
[0029] A first air flow opening 112 is disposed on the side of the first cover body 110, and a second air flow opening 113 is disposed on the bottom surface of the first cover body 110, so that the first hot air gap 101 and the second hot air gap 102 are connected through the first air flow opening 112 and the second air flow opening 113;
[0030] Specifically, a plurality of first air flow openings 112 are disposed on the side of the first cover body 110 , and hot air can enter the first hot air gap 101 from the first air flow openings 112 ;
[0031] A second air flow outlet 113 is provided on the peripheral side of the raised portion 111, and a plurality of second air flow outlets 113 are provided. The hot air enters the first hot air gap 101 from the first air flow outlet 112 and flows downward, and then flows back to the second hot air gap 102 from the second air flow outlet 113. The hot air moves upward to the first air flow outlet 112 again in the second hot air gap 102, and then enters the first hot air gap 101 through the first air flow outlet 112. In this way, the hot air circulation is continuously performed to heat the inner pot 200 and the food in the inner pot 200.
[0032] Furthermore, the first cover body 110 and the second cover body 120 are made of hardware materials.
[0033] In one embodiment, the second cover body 120 includes: a first body 121 and a second body 122; the first body 121 corresponds to the bottom of the first cover body 110, and the second body 122 corresponds to the side of the first cover body 110;
[0034] Specifically, Figure 2 As shown, the first body 121 is bowl-shaped and is correspondingly arranged at the bottom of the first cover body 110; the second body 122 is also bowl-shaped, and a return hole is arranged on the bottom surface of the second body 122, so that the hot air flowing out of the second air flow outlet 113 of the first cover body 110 can flow back to the second hot air gap 102 through the return hole;
[0035] The second body 122 is disposed on the first body 121 and covers the outside of the first cover 110 .
[0036] The first body 121 and the second body 122 can be made of metal materials respectively and then assembled.
[0037] Furthermore, the upper end of the second body 122 extends to be combined with the first cover body 110 or the outer shell 130 , and the second hot air gap 102 is isolated from the heat insulation gap 103 .
[0038] Furthermore, the first cover body 110 can be supported on the bottom surface of the second main body 122 to enhance the supporting performance and prevent the first cover body 110 from being deformed.
[0039] In one embodiment, a heating pipe 140 is mounted outside the first housing 110 .
[0040] Specifically, Figure 2 As shown, in the second hot air gap 102, heating tubes 140 are provided at the bottom and surrounding sides corresponding to the inner tank 200. The hot air enters the first hot air gap 101 from the first air flow outlet 112 and then flows downward, and then flows back to the second hot air gap 102 from the second air flow outlet 113. The hot air moves upward to the first air flow outlet 112 again in the second hot air gap 102, and then enters the first hot air gap 101 through the first air flow outlet 112, and the hot air circulation is continuously performed in this way. However, since the second hot air gap 102 is isolated from the insulation gap 103, the hot air does not enter the insulation gap 103, so that the heat is better isolated and the heating effect of the inner tank 200 is better.
