It should be noted that the structure of the steam guide 3 is not particularly limited in the present invention, and as a specific example, as shown in fig. 1, the steam guide 3 has a rod-like structure, but the steam guide 3 may have another structure as long as it can deliver steam into the inner container 2.

Preferably, as shown in fig. 1, the steam guide 3 is disposed in a region near a center line of the inner container 2, so that the food in the inner container 2 is heated more uniformly.

The steam heating unit and the auxiliary heating unit 4 can operate simultaneously, the steam heating unit heats food in the inner container 2, and simultaneously the auxiliary heating unit 4 heats the outer side of the inner container 2 synchronously, so that the temperature of the bottom wall and the outer side of the side wall of the inner container 2 is improved, the temperature difference of each area in the inner container 2 is reduced, the food in each area in the inner container 2 is heated uniformly, the cooking effect is improved, the probability of steam liquefaction in the inner container 2 can be reduced, the generation of condensed water is reduced, the taste of the food is improved, and further the user experience is improved.

The heat insulation gap 43 is arranged between the heating plate 41 and the bottom wall of the cooking cavity 11, so that the heat transferred from the heating plate 41 to the bottom wall of the cooking cavity 11 can be reduced, and the temperature rise of the pot body 1 is reduced. The mounting column 413 is connected with the bottom wall of the cooking cavity 11 in a matched mode, so that the mounting column 413 is closer to the bottom wall of the cooking cavity 11, the heat insulation piece 6 is sleeved on the periphery of the mounting column 413, a certain blocking effect is achieved on heat diffusion of the mounting column 413, a blocking effect on radiation of the heat of the mounting column 413 can be achieved, the mounting column 413 can be prevented from being in direct contact with the bottom wall of the cooking cavity 11, and therefore heat transmitted to the bottom wall of the cooking cavity 11 is reduced, and the pot body 1 is kept at a lower temperature.

Preferably, as shown in fig. 4, the auxiliary heating unit 4 further includes a heating member 42 fixedly connected to the heating plate 41, the heating member 42 is used for generating heat and transferring the heat to the heating plate 41, and the heating member 42 may be a heating tube, a PTC, a heating membrane, a ceramic sheet, or the like, as long as a certain heating power can be achieved. Preferably, the heat generating plate 41 is made of a material with good heat conductivity, such as metal.

Preferably, the heat insulating member 6 has a structure made of a material having a poor heat conductivity, and the heat insulating member 6 has a good heat resistance, such as silica gel, to prevent the heat insulating member 6 from being deformed or damaged at a high temperature.

It should be noted that, the heating manner of the auxiliary heating unit 4 is not specifically limited in the present invention, and the auxiliary heating unit 4 can heat the inner container 2 in a contact heat transfer manner, that is, the heating plate 41 abuts against the inner container 2 to transfer heat to the inner container 2. The auxiliary heating unit 4 may heat the inner container 2 by heat radiation, that is, the heating plate 41 is not in contact with the inner container 2, and the hot air heated by the heating plate 41 flows into the inner container 2 to heat the inner container 2.

As a preferred embodiment of the present invention, as shown in fig. 2, the bottom wall of the cooking cavity 11 is provided with a mounting hole 15 for the mounting post 413 to pass through, and at least a partial region of the heat insulating member 6 extends into the mounting hole 15 to avoid the mounting post 413 contacting with the mounting hole 15.

Because the heat transfer efficiency is high in a contact heat transfer mode, the heat insulation piece 6 is positioned between the mounting column 413 and the mounting hole 15, the mounting column 413 is prevented from being in direct contact with the bottom wall of the cooking cavity 11, and heat is prevented from being transferred to the bottom wall of the cooking cavity 11 in a contact heat transfer mode.

In the present embodiment, the connection manner of the mounting post 413 and the mounting hole 15 is not particularly limited, and the mounting post 413 may be fastened and connected to the mounting hole 15 so as to maintain the relative position between the heating plate 41 and the bottom wall of the cooking cavity 11, and preferably, the mounting post 413 passes through the mounting hole 15 and can move up and down along the mounting hole 15 so as to allow the heating plate 41 to float up and down, thereby improving the adhesion degree between the heating plate 41 and the inner container 2.

As a preferred embodiment of the present invention, as shown in fig. 4, the bottom wall of the cooking cavity 11 has a relief portion 12 recessed toward a direction away from the cooking cavity 11 to increase the heat insulation gap 43.

The arrangement of the avoiding portion 12 increases the thermal insulation gap 43, accelerates the circulation of air in the thermal insulation gap 43, accelerates the dissipation of heat, and as for the movable manner of the heating plate 41 shown in fig. 4, the avoiding portion 12 leaves a space for the up-and-down floating of the heating plate 41, increases the floating range of the heating plate 41, and prevents the heating plate 41 from contacting the bottom wall of the cooking cavity 11 when moving down.

Further, as shown in fig. 2, the heat insulating material 6 has a stopper portion 61, and the stopper portion 61 is placed against the upper end surface of the escape portion 12 so that the upper end surface of the stopper portion 61 is higher than the upper end surface of the escape portion 12.

The upper end face of the limiting portion 61 is higher than the upper end face of the avoiding portion 12, and limits the movement of the heating plate 41, for example, when more food is contained in the inner container 2, the inner container 2 is heavier in weight, when the inner container 2 is arranged on the heating plate 41, the heating plate 41 is pressed to deform or move, at the moment, the heating plate 41 can abut against the upper end face of the limiting portion 61 and cannot move downwards or deform continuously, so that the heating plate 41 cannot contact with the bottom wall of the cooking cavity 11, and the heating plate 41 is prevented from directly contacting with the avoiding portion 12 to transfer heat. For another example, when the heating plate 41 can float up and down, the heating plate 41 can not move downward when it sinks to contact with the upper end surface of the limiting portion 61, and thus cannot contact with the pot body 1.

As a preferred embodiment of the present invention, as shown in fig. 2 to 4, an elastic member 5 is provided between the heat generating plate 41 and the bottom wall of the cooking cavity 11, so that the heat generating plate 41 can float up and down to abut against the inner container 2.

Moreover, when the steam cooking appliance is a visual steam cooking appliance with an inner container made of glass, the height of the inner container made of glass has large difference due to the fact that the glass material is difficult to process and the processing error is large, and the opening of the inner container 2 is difficult to be matched with the pot cover in a sealing mode. The heating plate 41 can float up and down, so that when the height of the inner container 2 is higher, the inner container 2 presses the heating plate 41 to move downwards, the normal matching of the opening part of the inner container 2 and the pot cover is ensured, and the sealing between the opening part and the pot cover is kept effective. The error of the inner container 2 and the pot body 1 in the height direction is made up, and the requirement of installation precision is lowered.

In the present embodiment, the position of the elastic member 5 is not particularly limited, and includes but is not limited to the following examples:

example 1: in this embodiment, the elastic member 5 is disposed outside the heat insulating member 6.

The heat transmitted to the elastic piece 5 by the mounting column 413 is reduced, so that the elastic piece 5 works in a lower temperature environment, the service life and the reliability are improved, and the elastic piece 5 is prevented from being deformed or damaged at high temperature.

In the present embodiment, the elastic member 5 may be disposed at a position above, below, or the like the heat insulating member 6, and is not particularly limited herein, as a preferred example, as shown in fig. 3, the elastic member 5 is sleeved on the outer circumference of the heat insulating member 6 to reduce the overall height of the installation of the auxiliary heating unit 4, and has a simple structure, which facilitates the assembly of the heat insulating member 6 and the elastic member 5.

Example 2: in this embodiment, as shown in fig. 2, a deformation space 62 is provided between the thermal insulation member 6 and the mounting post 413, and the elastic member 5 is disposed in the deformation space 62.

The setting in deformation space 62 makes the deformation of elastic component 5 only can be followed the extending direction in deformation space 62 goes on, has improved right the limiting displacement of elastic component 5 makes elastic component 5 only can follow vertical direction deformation from top to bottom, and then guarantees generate heat dish 41 with the unsteady stability of inner bag 2 is avoided elastic component 5 takes place the slope.

Preferably, as shown in fig. 2, the bottom wall of the cooking cavity 11 is provided with a mounting hole 15 for the mounting column 413 to pass through, the steam cooking appliance further includes a limiting member 7 fixedly connected to the mounting column 413, an outer diameter of at least a partial region of the limiting member 7 is larger than an aperture of the mounting hole 15, and when the heat generating plate 41 floats upwards for a large distance, the limiting member 7 abuts against the bottom wall of the cooking cavity 11 to limit the movement of the heat generating plate 41.

As shown in fig. 2, the stopper 7 may be a screw, and the outer diameter of the screw head is larger than the diameter of the mounting hole 15, so that the mounting post 413 is prevented from being removed from the mounting hole 15. Of course, the limiting member 7 may have other structures as long as the outer diameter of at least a partial region of the limiting member 7 is larger than the bore diameter of the mounting hole 15, and is not particularly limited herein.
