In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1-3, in one embodiment, a steam generating device 10 is provided that includes an atomizing assembly 14 and a steam delivery channel 111. The atomizing assembly 14 is used for producing steam, and the steam delivery channel 111 is used for delivering the steam produced by the atomizing assembly 14 to a target chamber. Specifically, the steam generating device 10 may be applied to a dishwasher 20 or a steam-and-bake all-in-one machine. As shown in fig. 8 to 10, when the steam generating device 10 is applied to the dishwasher 20, the target chamber is a washing chamber 211 surrounded by the inner container 21. When the steam generating device 10 is applied to a steaming and baking all-in-one machine, the target cavity is a cooking cavity in the steaming and baking all-in-one machine.

Further, as shown in fig. 3, a heating member 12 is provided in the steam delivery passage 111, and the steam in the steam delivery passage 111 can be heat-exchanged through the heating member 12.

According to the steam generating device 10 provided by the scheme, the heating element 12 is arranged in the steam conveying channel 111, so that steam produced by the atomizing component 14 can be converted into high-temperature steam, the temperature of the steam conveyed into a target chamber through the steam conveying channel 111 is guaranteed to be high, and the sterilization effect is further improved. Also, the heating member 12 is directly disposed in the steam delivery passage 111, and the steam can directly contact the heating member 12 when flowing through the heating member 12, thereby improving the efficiency of heat exchange between the heating member 12 and the steam.

Specifically, as shown in fig. 3, 6 and 7, in one embodiment, the heating element 12 includes a heat generating tube 121 and a plurality of fins 122, which are both located in the steam delivery channel 111, the plurality of fins 122 are sequentially stacked, and the heat generating tube 121 is inserted into the plurality of fins 122.

The heat generated by the heat generating tube 121 can be transferred to the plurality of fins 122, and then when the steam passes through the heating member 12, the area of heat exchange with the heating member 12 is large, thereby further improving the heat exchange efficiency. And gaps are formed between the laminated fins 122 to allow steam to smoothly pass through the heating member 12. Then, the heat exchange area can be increased without obstructing the normal circulation of the steam by arranging more fins 122 in the steam conveying channel 111.

Alternatively, the heating element 12 may be another element capable of heating to provide heat.

Further, a plurality of the heating members 12 may be disposed in the vapor delivery passage 111. As shown in fig. 3 and 6, the plurality of heating members 12 may be electrically connected in series.

Further specifically, the vapor delivery passage 111 may be a passage dug directly in a housing enclosing the target chamber. Alternatively, as shown in fig. 1 to 3, the steam generating device 10 further includes a conveying pipe section 11, and the conveying pipe section 11 encloses the steam conveying channel 111. The heating element 12 is arranged in the conveyor pipe section 11.

Further, in one embodiment, the delivery pipe section 11 is provided with a terminal 1132, and the terminal 1132 is electrically connected to the heating element 12. The terminals 1132 may be connected to an external power source so that the heating member 12 can be energized to generate heat.

Further, in one embodiment, as shown in fig. 1 and 2, the conveying pipe section 11 comprises a first pipe section 112 and a second pipe section 113 which are sequentially communicated in the steam flow direction, and the first pipe section 112 and the second pipe section 113 are arranged at an included angle. The heating element 12 is disposed in each of the first pipe section 112 and the second pipe section 113. The temperature of the steam heated by the two heating members 12 is high. And the first pipe section 112 and the second pipe section 113 which are arranged at an included angle have low space occupation rate.

Further, in one embodiment, as shown in fig. 1 to 3, the steam generating device 10 further includes a water tank 13, and the atomizing assembly 14 is disposed in the water tank 13 for atomizing water in the water tank 13 into steam. The delivery tube segment 11 is in communication with the water tank 13 for delivering the steam to the target chamber. Specifically, the first pipe segment 112 communicates with the water tank 13.

The atomizing assembly 14 may be an assembly that includes atomizing plates and atomizes water into steam using high frequency oscillation, or other assembly capable of atomizing water into steam.

Further, when the first pipe section 112 and the second pipe section 113 are arranged at an included angle, as shown in fig. 1 to 3 and fig. 8 to 10, steam meets the pipe wall of the second pipe section and is partially condensed, the formed condensed water is deposited in the second pipe section 113, and the condensed water deposited in the second pipe section 113 is not easy to flow from the first pipe section 112 to the water tank 13. Therefore, as shown in fig. 1 to 3, in one embodiment, the steam generator 10 further includes a return pipe section 15, a condensed water return hole 1131 is formed in a position of the second pipe section 113 away from the first pipe section 112, one end of the return pipe section 15 is communicated with the condensed water return hole 1131, and the other end of the return pipe section 15 is communicated with the water tank 13. So that the condensed water in the second pipe section 113 can directly flow from the condensed water return hole 1131 to the water tank 13 through the return pipe section 15. The condensed water on the portion of the second pipe segment 113 close to the first pipe segment 112 can also flow from the first pipe segment 112 to the water tank 13, so that the condensed water return hole 1131 is disposed at a position far away from the first pipe segment 112, which can improve the return effect of the condensed water in the second pipe segment 113.

Further, as shown in fig. 3, in one embodiment, the included angle between the first pipe segment 112 and the second pipe segment 113 is less than 90 °. The first pipe section 112 is arranged along the longitudinal direction, and during the use process, the end of the second pipe section 113 far away from the first pipe section 112 has the tendency of inclining downwards. In this case, the condensed water returning hole 1131 is disposed on the second pipe section 113 at a position far from the first pipe section 112, which is more advantageous for recovering condensed water.

Further, in one embodiment, the end of the return pipe section 15 communicating with the water tank 13 is inserted below the water level in the water tank 13. Thereby preventing steam in the second pipe section 113 from flowing into the water tank 13 through the return pipe section 15.

And then when high-temperature steam flows out from the air outlet nozzle 1141, the flow rate is higher, so that the high-temperature steam can uniformly fill the whole target cavity.

Specifically, as shown in fig. 1 to 3, the outlet nozzle 1141 is an outlet of the output pipe segment 114.

More specifically, in one embodiment, as shown in fig. 2 and 3, the heating element 12 in the first tube segment 112 and the heating element 12 in the second tube segment 113 are electrically connected, and the terminal 1132 is disposed on the second tube segment 113. Further, as shown in fig. 2 and 3, the terminal 1132 may be located at a corner where the second pipe segment 113 is connected to the output pipe segment 114.

Further, in one embodiment, as shown in fig. 4 and 5, the water tank 13 is provided with a water inlet 132, and the position of the water tank 13 communicated with the conveying pipe section 11 is a water mist outlet 131.
