The liquid enters the vaporizing chamber 10a from the inlet 10c and falls into the guide channel 70a between the heat conducting body 711 and the second heat conducting body 73, the guide channel 70a formed between the heat conducting body 711 and the second heat conducting body 73 divides the liquid entering the vaporizing chamber 10a from the inlet 10c into two, and the unvaporized liquid and the vaporized gas need to flow through the guide channel 70a before flowing along the side wall of the heat conducting body 711 away from the first heat conducting groove 71a to the outlet 10d, so that the arrangement increases the flow path of the liquid and improves the heating efficiency.
In combination with the above, the first heat conductor 71 may further include a connection portion 713 and a bending portion 715, where the bending portion 715 is connected to an end portion of the heat conductive body 711 by the connection portion 713 and extends into the first heat conductive groove 73a through the second opening.
The liquid enters the vaporizing chamber 10a from the inlet 10c and falls into the guide channel 70a between the heat conductive body 711 and the second heat conductive body 73, the liquid which is not vaporized and the gas generated by vaporization are divided into two by the guide channel 70a, and flow through the guide channel 70a, then flow to the extension channel formed by the connection portion 713 and the side wall of the bending portion 715 facing the second heat conductive body 73 and the side wall of the second heat conductive body 73 facing the first heat conductive groove 73a, then flow to the side wall of the heat conductive body 711 away from the first heat conductive groove 71a along the side wall of the bending portion 715 away from the extension channel, and finally flow to the outlet 10d. The connection part 713 and the bending part 715 are additionally arranged on the first heat conductor 71, so that the length of the heat conduction channel is prolonged, the flow path of liquid is prolonged, the heating efficiency is improved, the heating speed is uniform, and the energy utilization rate is high.
A plurality of baffle plates 95 may be further provided at intervals on the heat conduction path, the height of the baffle plates 95 being lower than the heights of the first heat conductor 71 and the second heat conductor 73. The baffle plate 95 may be disposed in the guide passage 70a, the extension passage, and the flow path defined by the heat conductive body 711 and the inner wall of the vaporization chamber 10a at intervals.
The baffle plate 95 can prevent the liquid which is not completely vaporized from flowing from the inlet 10c to the outlet 10d, so that the vaporization completion rate of the liquid is ensured. The steam generator 100 can be used for producing steam appliances such as garment steamer, ironing machine and the like, and can avoid the phenomenon that the sprayed liquid wets clothes. Meanwhile, the baffle plate 95 can also reduce the width of the heat conducting channel, so that the liquid can be uniformly and finely sprayed out of the outlet 10d after being vaporized.
To further enhance the heat transfer efficiency within the vaporization chamber 10a, referring to fig. 5, the vaporization chamber 10a may be configured to: the inner wall of the vaporization chamber 10a adjacent to the heat generating member 30 (which may be the lower chamber wall of the vaporization chamber 10a in fig. 5) is convexly provided with a heat conduction protrusion 91. The heat conduction protrusions 91 are provided in plural, and the heat conduction protrusions 91 may be provided specifically on the inner wall surface of the vaporization chamber 10a near the heat storage chamber 10b. The provision of the heat conduction protrusions 91 increases the heat transfer area of the steam generator 100, increases the contact area of the liquid with the heat transfer portion inside the case 10, and improves the heating efficiency of the steam generator 100 and the vaporization efficiency of the liquid.
In order to improve the heating efficiency and the vaporization efficiency of the liquid, heat conducting ribs 93 may be further protruding on the surface of the heat conducting channel where the heat conducting plate 70 is located. The heat conducting ribs 93 are also provided so that they increase the contact area of the liquid with the heat transfer portion within the housing 10. The heat conductive ribs 93 may be provided on one side or both sides of the heat conductive plate 70, and may also be provided on the chamber inner side wall of the vaporization chamber 10a.
In providing the case 10 of the steam generator 100 of the present application, referring to fig. 2 and 3, the following embodiment may be employed: the housing 10 includes a housing main body 11 and a partition plate 13, a receiving chamber is formed in the housing main body 11, and an inlet 10c and an outlet 10d are provided in the housing main body 11 and communicate with the receiving chamber. The partition plate 13 is disposed in the accommodating chamber, and divides the accommodating chamber into a heat storage chamber 10b and a vaporization chamber 10a, and the heating element 30 is connected to the partition plate 13.
The partition plate 13 is provided to divide the accommodating chamber into the heat storage chamber 10b and the vaporization chamber 10a reasonably, so that the heat generating member 30 for generating heat energy can be firmly connected with the case body 11 through the partition plate 13. Meanwhile, the heating element 30 is connected with the partition plate 13 which divides the accommodating cavity into the heat storage cavity 10b and the vaporization cavity 10a, and the heat energy generated by the heating element 30 can be efficiently and rapidly transferred to the heat storage cavity 10b and the vaporization cavity 10a at two sides of the partition plate 13, so that the steam generator 100 is ensured to obtain enough heat energy to rapidly and efficiently vaporize the liquid entering the shell 10 of the steam generator 100 no matter the steam generator 100 is used in a charging mode or a power-off mode. Furthermore, the partition plate 13 is arranged so that the heat energy generated by the heating element 30 in the charging mode or the heat energy generated by the heat storage element in the power-off mode can be uniformly transferred to the vaporizing chamber 10a, so that the vaporized gas can be uniformly ejected from the outlet 10d.

When the steam generator 100 is provided with the partition plate 13, the heat conducting fins 50 can be abutted between the partition plate 13 and the inner wall of the heat storage cavity 10b, and the arrangement enables the heat generating element 30 to better transfer the heat generated by the heat generating element into the heat storage cavity 10b and absorb and store the heat by the heat storage element during the process of generating heat by energizing. When the heat storage member releases heat energy, the heat energy can be better transferred to the vaporization chamber 10a through the heat conduction fins 50 and the partition plate 13, and the heat transfer effect of the steam generator 100 and the vaporization efficiency in the vaporization chamber 10a can be improved.
