The BEST OPTION of carrying out the INVENTION

Next, I'll detail what about the described preferred embodiments of the present invention, shown on the attached drawings.

The principle of the steam generator according to a preferred variant implementation of the present invention will be described with reference to Fig. 6.

Essentially, the steam generator 100 includes a water chamber W for the water content, with the heater 200 mounted therein for heating water and steam chamber S for keeping steam from water heated by the heater 200. That is, steam is generated as the water in the water chamber W is heated by the heater 200, and the steam is retained in the steam chamber S temporarily and is discharged from the steam generator through the release of steam into the steam chamber S.

In Fig. 5 shows the steam generator 50, is known from the prior art, prior art rectangular shape, which has a water chamber W with a horizontal length L2, relatively greater than the vertical length L3. That is, the steam generator 50, is known from the prior art, the heater 55, mounted horizontally, has a vertical length of the water chamber W in thickness of the heater 55. Therefore, the horizontal length is greater to meet the requirements for the capacity of the water. In contrast, the steam generator of the present invention has a vertical length L4 of the water chamber W is relatively greater than the actual horizontal length L5. Rela is estwenno, the heater 200 is also actually installed in a vertical position. As is clear from Fig. 6, even though the vertical length of the water chamber W can be taken as the length L4 plot on which actually mounted the heater 200, the vertical length of the water chamber W can be taken as the vertical length L4, as is preferable that the water filled chamber slightly above the heater 200. Because the difference between L4 and L4 not too large, most of the water in the water chamber W is at level L4. Moreover, for the same reason, the horizontal length L5 of the water chamber W is the width of the site, which occupies a large part of the water chamber W, which actually contains water.

The steam generator of the present invention has the following advantages. Since the horizontal length L5 may be reduced in comparison with steam prior art, when the content of the same quantity of water, preventing impact between the tank 20 and the steam generator 100 may be reduced. From the experiment, the present inventor, it is known that the present invention can reduce the consumption of water and the period of time to generate steam, and the steam is the same that is produced by the device known from the prior art. Accordingly, in General, the present invention can reduce the amount which the steam generator 100.

At the same time, it is preferable that the horizontal length L6 of the steam chamber S was relatively greater than the horizontal length of the water chamber W, because in General steam S camera has a hole for the water supply and the outlet of the steam, and has installed therein a water level sensor and temperature sensor. However, in this case, it is preferable that the horizontal length L6 of the steam chamber S was reduced in comparison with the device known from the prior art. That is, it is preferable that the horizontal length L6 of the steam chamber S was at least the same or less compared with the device known from the prior art.

At the same time, the vertical length L4 of the water chamber W can be made relatively smaller than the horizontal length L5 in various schemes. For example, as shown in Fig. 6-8, the horizontal length of the water chamber W can be fixed in the vertical direction. In cases, as shown in Fig. 8, the water chamber W can be tilted with respect to the steam chamber S under a predefined angle. As shown in Fig. 6 and 7, for reasons of manufacture of the steam generator 100, it is preferable that the water chamber W was not tilted with respect to the steam chamber S. In this case, as shown in Fig. 6, it is preferable that the water chamber W had the camping, essentially in the center of the steam chamber S.

As shown in Fig. 9, the horizontal length of the water chamber W can be reduced down. From the experiment conducted by the inventor, it is known that any steam generator shown in Fig. 6-8, has a lower water consumption compared with the generator shown in Fig. 9, and any steam generator shown in Fig. 6-8, has a shorter period of time of formation of steam than steam generator shown in Fig. 9. This is because the steam generator shown in Fig. 9, contains more water, if you use the heater of the same size.

At the same time, it is preferable that the steam generator 100 includes a lower housing which actually performs the function of the water chamber W, and the upper casing, which is attached to the top of the lower housing and actually performs the function of the steam chamber S. of Course, depending on the position of attachment of the upper casing to the lower casing, a water chamber W and the steam chamber S can divide the functions of the water chamber W or steam chamber S to a certain extent, but the bottom cover mainly performs the function of the water chamber W, and the upper casing mainly performs the function of the steam chamber S.

In this case, since the standard products having a common electrode, the electrode low water level and the electrode of the high water level is typically used as the sensor 300 water level, it is preferable that the General Assembly of the sensor 300 water level was used as is, except that the electrode a high water level Assembly of the water level sensor is not used, but uses a separate electrode 316 high water level. Preferably, the casing 318 electrode of the high level of the odes, for example, cylindrical wall, was additionally equipped to protect the electrode 316 high water level, placed apart from the other electrodes. By doing this, you can prevent false triggering of the sensor 300 water level caused by splashes between the electrode 316 high water level electrode 314 low water level.

At the same time, as described above, the upper casing 120 has an outlet 124 for steam release. The outlet 124 is equipped with a separator 420 to isolate the space, in which steam is blown out, in fact, from another space. While the water heated in the water chamber W, especially at the initial stage of heating, because the water and the bubbles strongly razbrasivayutsya, the separator 420 prevents splashing of water into the drum through the outlet 124.
