Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a steam cleaning device that is mainly used for dental techniques, such as the production of porcelain teeth used as dental prostheses.

(B) Prior Art In the steam cleaner manufactured by Shofu Co., Ltd., which precedes the present invention, as shown in Fig. 5, water from a water storage tank 1 is sucked into a water supply pump 3 through a water softener 2, and the intake water is passed through the water supply pump. 3, the superheated steam generated in the boiler 4 is supplied to the boiler 4 through the solenoid valve 5.
The steam is ejected from the nozzle 8 of the hand piece 7 via the steam hose 6 and the like.

However, with this type of steam cleaner,
Since the water storage tank 1 is disposed outside the main body case 9, this water storage tank 1 may become an obstacle or spoil the aesthetic appearance, and the water softener 2 is housed in the water storage tank 1. water softener 2
When inspecting the water softener 2, there is a drawback that the water softener 2 with water stains must be touched and removed.

(c) Problems to be solved by the invention The present invention solves the above-mentioned drawbacks, integrates the entire device without making the water storage tank an obstacle, and makes it possible to inspect the water softener cleanly and easily. It is something to do.

(d) Means for Solving the Problems The present invention uses a water supply pump to supply water from a water storage tank to a boiler through a water softener, and blows out superheated steam generated in the boiler from a handpiece. and a device in which parts such as the boiler are housed in a main body case, wherein the water softener and the water storage tank are independently housed in the main body case, and the water storage tank can be pulled out forward to the bottom of the main body case. It was placed in

(e) Effects According to the present invention, the water tank is integrally stored in the main body case without becoming an obstacle, and even if it is stored, it can be easily inspected by pulling it forward from the main body case. Also, the water softener can be taken out directly from the main case without any water stains.

(f) Examples Next, one embodiment of the present invention will be described.

In Figure 1, 10 is a water storage tank that stores tap water, etc., and 11 is a water softener that softens tap water, etc. It is filled with ion exchange resin and removes calcium from tap water, etc. to supply water with calcium. This prevents the conduit 12 from closing. The water softener 11 requires periodic inspection to replace the ion exchange resin, etc. A water supply pump 13 sucks water from the water storage tank 10 through the water softener 11 and discharges it to the check valve 14 side. A boiler 15 is supplied with water by the water pump 13, and is equipped with an electric heater (not shown). Reference numeral 16 denotes a pressure switch connected to the steam pipe line 17, which maintains the superheated steam pressure constant by turning on and off the electric heater of the boiler 15 based on the detection result. 18 is a safety valve, 19 is a manually operated electromagnetic valve, 20 is a steam hose, and 21 is a hand piece, which has a steam jet nozzle 22.

In FIG. 2, 23 is a main body case of the steam cleaning device, which includes the water supply pump 13 and the boiler 1.
It stores 5th grade. The main body case 23 has side parts 24, 25 and a top part 26 integrally molded, and can be assembled by removing a plurality of assembly screws (not shown).
The side portions 24, 25 and the upper surface portion 26 are configured to be integrally separated from the front surface portion 27 and removed upwardly. Further, the front part 27 includes an opening/closing lid 2 for inserting and removing the water storage tank 10.
8 is provided. The opening/closing lid 28 is opened by rotating outward as shown by the arrow by loosening an operating screw 29 provided at its upper end.

Therefore, the water softener 11 and the water storage tank 1
0 are housed independently in the main body case 23, as shown in FIGS. 3 and 4. Further, the water storage tank 10 is disposed at the bottom of the main body case 23 in such a manner that it can be pulled out forward. Specifically, the water softener 11 is set on the upper part of the partition plate 30 of the main body case 23, and can be easily attached and detached from the main body case 23 by removing the main body case parts 24, 25, 26, etc. There is. The water storage tank 10 is adapted to be pulled out by smoothly sliding along rail portions 35, 36 of side frames 33, 34 to which support legs 31, 32 are attached.

In the steam cleaning apparatus, when the power switch (not shown) is turned on, the water supply pump 13 and the electric heater of the boiler 15 are energized, and the boiler 15 is turned on.
Superheated steam with a pressure of about 7 kg/cm ² is generated at a temperature of about 170°C, and this superheated steam passes through the open electromagnetic valve 19 and flows from the steam hose 20 to the handpiece 2.
1 and ejects from the nozzle 22.

Moreover, the water softener 11 and the water storage tank 10 can be easily attached to and detached from the main body case 23 by opening the case parts 24, 25, 26 and the opening/closing lid 28, respectively.

(g) Effects of the invention Since the invention is constructed as described above, by storing the water storage tank in the main body case, the entire device can be made compact without the water storage tank becoming an obstacle outside the main body case, and the water softener can be softened. It is possible to inspect the vessel in a clean state without adhesion of water stains without requiring the work of taking it out from the water storage tank as in the conventional example, and it is therefore possible to provide a compact and easy-to-use steam cleaning device.
