Describe the structure of so above-mentioned safety device 110 below in detail.
Said temperature is regulated control part 140 and is used for by user's operation the heating wire 22 that is incorporated into above-mentioned hot water pipe 20 inside being switched on/being cut off the power supply, and is the common control part that can regulate temperature.And, carry out the following setting of appending: make said temperature regulate control part 140 and be electrically connected, when unusual (short circuit) action takes place safety device 110, detect this abnormal operation, with whole dump with above-mentioned safety device 110.
Fig. 5 is the schematic diagram that the related safety device of the preferred embodiments of the present invention is shown.
With reference to accompanying drawing, safety device 110 of the present invention constitutes substantially and comprises: attaching parts 112; Main body 118, it is connected with above-mentioned attaching parts 112; And detecting unit 120, it is arranged at the inside of aforementioned body 118.
Above-mentioned attaching parts 112 are a kind of flexible pipes that pressure accommodation apparatus 40 and main body are connected with each other.Herein, the connection of above-mentioned attaching parts 112 can adopt multiple mode to realize, but preferably connects by general pipe joint.
Above-mentioned detecting unit 120 constitutes and comprises: support bar 122; Buoyancy member 130, itself so that the mode that above-mentioned support bar 122 inserts wherein be provided with; And electric wire 129, it is electrically connected with adjustment control part 140, and above-mentioned support bar 122 is formed with spire, top card hanging platform 125 and the bottom card hanging platform 126 that screws togather with nut N successively, and has lead-in wire 128 in above-mentioned support bar 122 inside.And above-mentioned buoyancy member 130 is arranged between top card hanging platform 125 and the bottom card hanging platform 126 under the situation that above-mentioned support bar 122 is inserted wherein, and is formed with banded magnet 132 at above-mentioned buoyancy member 130 inner surfaces.And above-mentioned buoyancy member 130 had obtained the insertion of support bar 122 before the bottom card hanging platform 126 that forms support bar 122.In addition, said wires 129 is electrically connected the lead-in wire 128 and the adjustment control part 140 of above-mentioned support bar 122.
Consequently, the support bar 122 that buoyancy member 130 accompanies is introduced in main body 118 inside, and is outstanding from the combined hole 116 that is formed at lid, utilizes nut N to fix firmly.Certainly, the electric wire 129 of connection lead-in wire 128 and adjustment control part 140 can prolong.
Fig. 6 (a) and (b) are work sheets of the related safety device of the preferred embodiments of the present invention.
At first, with reference to Fig. 6 (a), though it is not shown herein, attaching parts 112 are connected with a side of pressure accommodation apparatus 40, said temperature is regulated control part 140 and is provided with as follows: when with safety device 110 that adjustment control part 140 is electrically connected on when being short-circuited, with whole device outage, before the manager checks laggard horizontal reset, do not make power connection (ON).
And the main body 118 of safety device 110 is interconnected by attaching parts 112 and pressure accommodation apparatus 40, possesses detecting unit 120 in main body 118 inside.Promptly, possesses support bar 122 in main body 118 inside, this support bar 122 is clamped by buoyancy member 130, and the top of support bar 122 is outstanding and fix with nut N from combined hole 116, prolongs and is electrically connected with adjustment control part 140 to top with lead-in wire 128 wire connecting 129.At this moment, above-mentioned support bar 122 comes support fixation by top card hanging platform 125 and nut N, so can firmly fix.
Herein, with reference to the partial enlarged drawing shown in the side as can be known, the terminal part of lead-in wire 128 and the magnet 132 of buoyancy member 130 are positioned at same horizontal line, so can switch on.Certainly, said temperature adjusting control part 140 is arranged to this state recognition to being in the regular event.
Herein, with reference to Fig. 6 (b), show owing to accommodate the situation that pleated tube 46 breakages of pressure cause leaking from pressure accommodation apparatus 40 water that heats.And the heating water of leakage is accommodated in the main body 118 by attaching parts 112 inflows of safety device 110, and by this heating buoyancy of water of accommodating, buoyancy member 130 rises on the top of support bar 122.
At this moment, different with the situation of above-mentioned Fig. 6 (a) with reference to the partial enlarged drawing shown in the side, because the rising of buoyancy member 130, the terminal part of lead-in wire 128 and the magnet 132 of buoyancy member 130 are not positioned at same horizontal line.Like this, lead-in wire 128 and magnet 132 short circuits, the adjustment control part 140 of Dian Lianjieing detects short circuit with it, to whole device outage.
The user cuts off whole power supply by this way, so can know the misoperation of hot water pipe 20 at an easy rate.Thus, change after the pleated tube 46 of pressure accommodation apparatus 40, the heating water of accommodating in the main body 118 with safety device 110 empties, and then, adjustment control part 140 is resetted, and reverts to original state, restarts.
In addition, the structure 100 of the hot water pipe that safety arrangement in accordance with the present invention possessed, when from pressure accommodation apparatus 40 leakage heating water, the detecting unit 120 of safety device 110 detects this leakage situation rapidly, make the adjustment control part 140 that is electrically connected with safety device 110 cut off whole power supply immediately, improve security, and, when taking place to leak, cut off whole power supply, the manager can know immediately leaks, so can keep in repair rapidly, safeguards easily.
In addition, can prevent to improve security because of heating water leaks the electrification cause etc. second, accident for the third time.
In order to understand the claim scope of aftermentioned invention more easily, what disclose feature of the present invention and technological merit in a wide range in the above-mentioned content.The supplementary features and the advantage that constitute claim scope of the present invention will be narrated below.Those skilled in the art should understand, and disclosed design of the present invention and specific embodiment can be used as to be used to carry out with other structure Design of the similar purpose of the present invention or the basis of modification and use.
In addition, the design of invention disclosed and embodiment are for realizing that identical purpose of the present invention revises or be designed to the basis of other structure among the present invention, under the invention thought that those skilled in the art can put down in writing and the situation of scope, the present invention is carried out multiple modifications and changes in not breaking away from claim scope of the present invention.
