An electric stewpot 100 in accordance with an embodiment of the present application is described below with reference to fig. 1-6.

As shown in fig. 1-3, an electric stew cup 100 according to an embodiment of the present application includes a water tank 10 having a water bath space, a stew cup 30 selectively placed in the water bath space, and a heating member disposed at the bottom of the water tank 10.

The center of the bottom surface of the water tank 10 is provided with a mounting hole 11, a water retaining structure 20 is arranged around the mounting hole 11, the outer ring of the water retaining structure 20 is smoothly connected with the bottom surface of the water tank 10, the connection point 22 of the water retaining structure and the bottom surface of the water tank 10 are positioned on the same plane, the inner ring of the water retaining structure 20 is provided with a mounting part 23 for mounting a heating element 40, and the vertex 21 of the inner ring is the highest point of the water retaining structure 20 and forms a height difference with the connection point 22, so that when the heating element 40 is in a dry burning state, water is spaced from the heating element 40.

Particularly, water tank 10 opens the setting, its opening up, water tank 10 inner space is the water bath space, water and stewing handleless cup 30 can be deposited in the water bath space, mounting hole 11 has been seted up at the center of the bottom surface of water tank 10, heating member 40 sets up in mounting hole 11, stewing handleless cup 30 places behind the water bath space, it is located heating member 40's top, stewing handleless cup 30 sets up with heating member 40 interval, heating member 40 heats the water in the water tank 10, as heat transfer medium through water, the water after being heated is with heat transfer to stewing handleless cup 30 and then heat the food in stewing handleless cup 30.

It should be noted that the water retaining structure 20 is arranged around the mounting hole 11, one side of the water retaining structure 20 close to the mounting hole 11 is an inner ring of the water retaining structure 20, one side of the water retaining structure 20 far away from the mounting hole 11 is an outer ring of the water retaining structure 20, the outer ring of the water retaining structure 20 is smoothly connected with the bottom surface of the water tank 10, a connection point 22 of the water retaining structure 20 is arranged at a connection position of the outer ring of the water retaining structure 20 and the bottom surface of the water tank 10, and the connection point 22 is the lowest point of the water retaining structure 20; the inner ring part of the water retaining structure 20 protrudes towards the water bath space, the highest point of the protrusion is the vertex 21 of the inner ring, which is the highest point of the water retaining structure 20, the inner ring of the water retaining structure 20 is higher than the bottom surface of the water tank 10, the inner ring part of the water retaining structure 20 extends towards the bottom of the water tank 10 to form a mounting part 23, and the heating element 40 is mounted in the mounting part 23.

The water in the water tank 10 is continuously evaporated in the heating process, the water level is continuously reduced, when the water level is reduced to a lower liquid level, that is, when the water in the water tank 10 is reduced to a height corresponding to the vertex 21 of the inner ring of the water retaining structure 20, the water in the water tank 10 is at the lower liquid level, at this time, the vertex 21 of the inner ring of the water retaining structure 20 divides the water in the water tank 10 into two parts, the first part is the water between the water retaining structure 20 and the heating element 40, the second part is the water between the water retaining structure 20 and the inner wall of the water tank 10, and the water retaining structure 20 separates the two parts and blocks the water of the second part from flowing towards the heating element 40.

Furthermore, in the process of descending water in the water tank 10, the heating element 40 is in a state of continuous operation, because the water baffle structure 20 divides water below a lower liquid level into two parts, the heating element 40 only heats the first part of water, so that the water level of the first part of water is continuously descended without influencing the second part of water, and therefore, the water level of the second part of water is kept unchanged. After the heating member 40 evaporates the water of the first portion entirely, the water level of the second portion of water remains unchanged, at this moment, the heating member 40 can be in the dry combustion state, the water of the second portion below the lower liquid level can be left in the water tank 10, when the heating member 40 is in the dry combustion state, the heating member 40 can trigger the dry combustion protection, it can auto-power-off, at this in-process, the water tank 10 is always in the water state, the water in the water tank 10 can not be completely burnt, can avoid the water tank 10 to be in the dry combustion state.

According to handleless cup 100 is stewed to electricity according to this application embodiment, through setting up water retaining structure 20, can avoid in water tank 10 when falling to lower liquid level under water, heating member 40 top is all gathered to remaining water in the water tank 10 to avoid the water in the water tank 10 to be burnt completely, remaining water can trigger cooling water tank 10 before the protection action is burnt futilely at heating member 40 in the water tank 10, has reduced the potential safety hazard, has improved the safety in utilization.

It can be understood that, in the prior art, the water level in the water tank 10 gradually decreases under the heating action of the heating element 40, and the heating element 40 will trigger the dry-fire protection action after the water in the water tank 10 is completely dried, whereas in the present application, when the water level in the water tank 10 decreases to a lower level, at least a part of water may be separated by the water retaining structure 20, and the water above the heating element 40 will be gradually dried until the heating element 40 enters the dry-fire state and triggers the protection action, and before the heating element 40 triggers the protection action, at least a part of water in the water tank 10 is not dried, so that the dry-fire state of the water tank 10 can be avoided.

In some embodiments, the mounting hole 11 is a circular through hole, and the water blocking structure 20 is provided in a ring shape.

Particularly, mounting hole 11 has been seted up at the center of the bottom surface of water tank 10, mounting hole 11 is circular shape through-hole manger plate structure 20 structure and is the annular structure, it encircles mounting hole 11 setting, heating member 40 can be by the opening part of water tank 10 packing into water tank 10, and fix in installation department 23, heating member 40 is to the water heating in the water tank 10, the inner circle of manger plate structure 20 encircles the outside at heating member 40, thus, through setting up mounting hole 11, set up manger plate structure 20 along 11 circumferences of mounting hole, be convenient for fixed heating member 40, and it is simpler to set up the structure like this, manger plate structure 20 can block the water of lower liquid level in the water tank 10, improve the effect of dividing water.

Specifically, the heating member 40 is a heating plate. The kind of heating member 40 has the multiple, in this embodiment, heating member 40 adopts the heating plate, the heating plate is placed in mounting hole 11, the setting is in the bottom of water tank 10, it is fixed in installation department 23, the quotation of heating plate and the water direct contact in the water bath space, directly heat water, set up heating member 40 into the heating plate, the installation of being convenient for more, and the heating plate occupation space is little on the direction of height, the heating plate is big with the area of contact of water, can be to the water rapid heating in the water tank 10.

In some embodiments, the pan face is flush with the highest point of the dam 20, or the pan face is slightly below the highest point of the dam 20.
