[0036] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Example: Refer to Figure 1-Figure 3 , a steam heating device, comprising:

[0038] The box body 1 defines a control chamber and a heating chamber inside;

[0039] A heating unit is arranged in the heating chamber and is configured to generate a first heat radiation in a turned-on state;

[0040] A pair of functional sheets 2 are arranged at the top / bottom of the heating chamber, and are configured to release / absorb superheated steam in the heating chamber, so as to form a bottom-to-top cyclic heat conduction in the heating chamber;

[0041] The control mechanism includes a first control part electrically connected to the heating unit, and the heating unit has a switchable open / closed state through the first control part. It also includes a second control part, and the control ends of the second control part are respectively connected to a pair of functional sheets 2 to form a pair of functional sheets 2 to generate a second heat radiation in the heating chamber.

[0042] The utility model defines a control chamber and a heating chamber in a box body 1, respectively, arranges a heating unit and a pair of functional sheets 2 in the heating chamber, and uses a control mechanism to control the two separately, so that the heating unit releases a first heat radiation in the heating chamber when in an on state, and in addition, the pair of functional sheets 2 releases superheated steam from bottom to top in the heating chamber to form a cyclic heat conduction, the heating unit is controlled to open and close by a first control unit, and the second control unit controls the pair of functional sheets 2 to generate superheated steam for heating, and controls the second heat radiation to be conducted in a top-to-bottom direction, thereby forming a cyclic alternating heat transfer effect in the heating chamber, ensuring the uniformity of heating in the heating chamber, recovering and heating the cooled superheated steam, maintaining the heating effect, and ultimately achieving the effect of enhancing the steaming and baking efficiency.

[0043] Furthermore, the second control unit includes:

[0044] The absorption box 3 is arranged in the control chamber, and one end of the absorption box 3 is connected to the uppermost functional sheet 2 through a plurality of first connecting pipes 5. When the superheated steam is absorbed in the heating chamber, the superheated steam moves along the uppermost functional sheet 2 to the absorption box 3;

[0045] A release box 4 is arranged in the control chamber, one end of which is connected to the bottom functional sheet 2 through a plurality of second connecting pipes 6. When the superheated steam is released in the heating chamber, the superheated steam moves along the release box 4 to the bottom functional sheet 2.

[0046] The conveying unit is disposed in the control chamber and is configured so that the superheated steam can move along the absorption box 3 to the release box 4 through the conveying unit.

[0047] By arranging an absorption box 3, a release box 4 and a corresponding conveying unit in the control chamber, the absorption box 3 and the first connecting pipe 5 are used to recover the superheated steam from the heating chamber, and the recovered superheated steam is reintroduced into the heating chamber through the release box 4 and the second connecting pipe 6. During the process, the superheated steam is heated to keep the heating effect at all times, thereby achieving sufficient and uniform heating of the heating chamber and improving the heating efficiency.

[0048] Furthermore, the conveying unit comprises:

[0049] A first pump 7 is fixed in the control chamber and connected to the absorption box 3. When the first pump 7 is started, the absorption box 3 can generate a suction effect from the heating chamber to the control chamber;

[0050] The second pump 8 is fixed in the control chamber and connected to the release box 4. When the second pump 8 is started, the release box 4 can produce a release effect from the control chamber to the heating chamber.

[0051] As one of the pair of functional sheets 2 releases the superheated steam into the heating chamber, the steam rises due to the heat and its temperature drops after passing through the heated object. Then, the first pump 7 is started to generate suction force in the absorption box 3, and the superheated steam is recovered by the other functional sheet 2. After repeated heating to provide thermal effect of the superheated steam, the second pump 8 is started to re-introduce the superheated steam into the heating chamber, thereby improving the heating effect of the superheated steam.

[0052] Furthermore, it also includes:

[0053] The steam generator 9 is fixed in the control chamber, and its two ends are connected with the absorption box 3 and the release box 4 through pipelines respectively. The steam generator 9 is used to prepare superheated steam.

[0057] The liquid storage tank 11 is fixed in the control chamber, and the two ends of the liquid storage tank 11 are respectively connected to the cooling tank 10 and the steam generator 9, wherein one end of the liquid storage tank 11 is connected to the outside of the box body 1 through the liquid replenishing pipe 12. When the superheated steam in the heating chamber is absorbed / released, the superheated steam moves from the cooling tank 10 to the liquid storage tank 11.

[0058] Correspondingly, one side of the absorption box 3 is connected to the cooling tank 10 to condense the recovered cooled superheated steam, and then the condensed water is passed into the liquid storage tank 11, and connected to the steam generator 9 through the liquid storage tank 11 to achieve repeated heating of the condensed water to prepare superheated steam, providing a second heat radiation effect, and one end of the liquid storage tank 11 is connected to the outside through the liquid replenishment pipe 12, which is convenient for replenishing water in the liquid storage tank 11 to ensure the steam heating effect.

[0059] Furthermore, it also includes:

[0060] A first solenoid valve 13 is arranged at the communication end between the absorption box 3 and the cooling tank 10;

[0061] The second solenoid valve 14 is arranged at the communication end between the cooling tank 10 and the liquid storage tank 11 .

[0062] The connection between the absorption box 3 and the cooling tank 10 is controlled by the first solenoid valve 13, so that the recovered superheated steam moves from the absorption box 3 to the cooling tank 10. Similarly, a second solenoid valve 14 is set at the connecting end between the cooling tank 10 and the liquid storage tank 11 to realize the connection control thereof, so that the condensed water can be passed into the liquid storage tank 11 for reuse.

[0063] Furthermore, the heating unit comprises:

[0064] A controller 15 is fixed in the control cavity;

The heating coil 16 is controlled by the controller 15 to provide the first heat radiation to the heating cavity, which not only supplements the heating effect in the heating cavity, but also heats the superheated steam, reduces the impact of the reduction of the superheated steam temperature, and further improves the heating effect.

[0066] Furthermore, the functional sheet 2 is an annular structure, a cavity is defined inside the functional sheet 2, a plurality of through holes are axially and evenly spaced on one side of the functional sheet 2 close to the heating cavity, and the cavity is connected with the heating cavity through the through holes.

[0067] By arranging the functional sheet 2 in a ring structure and opening through holes on the functional sheet 2 toward the heating chamber, the steam entering the heating chamber can be evenly diffused to ensure uniform heating, while also increasing the rate of absorbing superheated steam and enhancing the heating effect.

[0068] The working process of this embodiment is as follows:

[0069] The superheated steam is recovered from the heating chamber by using the absorption box 3 and the first connecting pipe 5, and the recovered superheated steam is reintroduced into the heating chamber through the release box 4 and the second connecting pipe 6. As one of the pair of functional sheets 2 releases the superheated steam into the heating chamber, the steam rises due to the heat, and its temperature drops after passing through the heated object. Then the first pump 7 is started to generate a suction force in the absorption box 3, and the superheated steam is recovered by using the other functional sheet 2. After repeated heating to provide the superheated steam thermal effect, the second pump 8 is started to reintroduce the superheated steam into the heating chamber. The recovered cooled superheated steam is condensed, and the condensed water is then passed into the liquid storage tank 11, which is connected to the steam generator 9 through the liquid storage tank 11 to achieve repeated heating of the condensed water to prepare superheated steam and provide a second thermal radiation effect. One end of the liquid storage tank 11 is connected to the outside through the liquid replenishment pipe 12, which is convenient for replenishing water in the liquid storage tank 11 and enhancing the steam heating effect.
