the lower cover 8 is connected with the lower side of the heating main body 1 to form a second cavity 9, a third flow passage 10 and a fourth flow passage 11 which are mutually independent are arranged in the second cavity 9, one end of the third flow passage 10 is communicated with the first flow passage 6 through a first through hole 12 arranged on the heating main body 1, the other end of the third flow passage 10 is communicated with one end of the second flow passage 7 through a second through hole 13 arranged on the heating main body 1, the other end of the second flow passage 7 is communicated with the fourth flow passage 11 through a third through hole 14 arranged on the heating main body 1, and the fourth flow passage 11 is communicated with the outlet 3;
a heating element 15 provided on the heating body 1;
the power module 16 is electrically connected to the heating element 15.
The double-layer cavity type steam generator of the embodiment adopts a double-layer cavity design, so that when fluid circulates in two cavities, the fluid in a target state is heated favorably, the heat exchange efficiency is best, and the steam generation efficiency is improved. Simultaneously, each cavity is internally provided with two mutually independent flow passages, and four flow passages form a fluid circulation route from top to bottom and from bottom to top to bottom, thereby being beneficial to dry-wet separation of steam and improving the dryness of outlet steam.
With continued reference to fig. 1 and with further reference to fig. 7, in a specific embodiment, the dual-cavity steam generator further includes a temperature control device, where the temperature control device includes a temperature control switch 17, and the temperature control switch 17 is connected in series with the heating element 15. It should be noted that, heating element and temperature control switch are directly established ties in the circuit, and temperature control switch self has an off-temperature and a reset temperature, and when the temperature of heating main part is too high, reaches the off-temperature, temperature control switch just opens, and power module no longer supplies power to the heating element, and steam generator stops working, and when heating main part temperature drops, reaches the reset temperature, temperature control switch just recloses, and power module continues to supply power to the heating element, and steam generator continues to work. The steam generator is enabled to work stably through the temperature control switch, and faults of the steam generator due to overhigh temperature are prevented. In this embodiment, the temperature control switch is an existing temperature control switch in the market.
With continued reference to fig. 1, in one embodiment, the temperature-controlled switch 17 is disposed on the upper cover 4.
In another specific embodiment, the temperature control switch is arranged on the lower cover.
With continued reference to fig. 1 and 7, in a specific embodiment, the temperature control device further includes a controller 18 and a temperature sensor 19 communicatively connected to the controller 18, where the temperature sensor 19 is mounted on the upper cover 4 by a fixing member 20 and is located at the outlet 3; the temperature control switch 17 is electrically connected with the controller 18, and when the outlet steam temperature measured by the temperature sensor 19 exceeds the set temperature, the controller 18 controls the temperature control switch 17 to be opened so as to disconnect the circuit between the power supply module and the heating element. The temperature sensor detects the temperature of the sprayed steam and sends the detected temperature to the controller, and when the temperature of the steam sprayed from the outlet is higher than a set value, the controller controls the temperature control switch to be turned off, the power supply is directly cut off, and the steam generator stops working. The steam is prevented from being excessively high, and the temperature of the generated steam is unstable. In this embodiment, the temperature sensor is a commercially available temperature sensor.
With continued reference to fig. 1-6, in particular, in one embodiment, the inlet and the outlet are provided at the same end of the heating body.
Specifically, in another embodiment, the inlet is provided at one end of the heating body and the outlet is provided at the other end of the heating body.
Specifically, in one embodiment, the length of the first flow channel is smaller than the length of the second flow channel, and the length of the fourth flow channel is smaller than the length of the third flow channel. The fluid firstly enters the first flow passage from the inlet, then sequentially enters the third flow passage and the second flow passage, finally enters the fourth flow passage, and the generated steam flows out from the outlet. Because the first runner inlet is communicated, the fourth runner is communicated with the outlet, and when the fluid circulates, the lengths of the second runner and the third runner are designed to be longer than those of the first runner and the fourth runner, so that the fluid is heated uniformly, and the heat exchange efficiency and the dryness of the outlet steam are improved.
Specifically, with continued reference to fig. 1 and 3 to 5, threaded holes 21 are formed on both sides of the end portion and both sides of the middle portion of the heating body 1, and the upper cover 4 and the lower cover 8 are fixedly mounted on both sides of the heating body 1 through the threaded holes 21 and screws (not shown in the drawings), respectively.
The working principle of the double-layer cavity outlet type steam generator is as follows:
referring to fig. 3 to 5, when the steam generator is in operation, the power module supplies power to the heating element, the heating element starts to operate, fluid enters the first flow channel of the first cavity from the inlet and contacts the heating layer of the heating main body to generate steam, the steam and unvaporized fluid enter the third flow channel of the second cavity from the first through hole at the tail end of the first flow channel, the unvaporized fluid continuously vaporizes the generated steam in the third flow channel, the steam enters the second flow channel of the first cavity from the second through hole at the tail end of the third flow channel, enters the fourth flow channel from the third through hole at the tail end of the second flow channel, and finally flows out from the fourth flow channel through the outlet.
Referring to fig. 6, when the fluid circulates in the first chamber, the fluid is located under the steam under the influence of gravity, i.e., above the heating layer of the heating body, so that the fluid is continuously evaporated by heat; correspondingly, when the fluid circulates in the second cavity, the steam is contacted with the heating layer, so that the steam is further heated and vaporized, the vaporized steam enters the second flow passage of the first cavity from the third flow passage of the second cavity, then enters the fourth flow passage of the second cavity from the second flow passage, and finally flows out from the outlet, and the steam flows out from the lower to the upper and then downward circulation paths, so that the dry and wet separation of the steam is facilitated, and the steam flowing out from the outlet is further dried.
The fluid in this embodiment is not limited to water, and may be a mixed solution of a cleaning solution and a person.
The above-described embodiments are intended to illustrate the present utility model, not to limit it, and any modifications and variations made thereto are within the spirit of the utility model and the scope of the appended claims.
