Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jar pot, particularly a jar pot having a safety device built in a power plug.

[0002]

[Prior Art]

 As a conventional jar pot, for example, as shown in FIG. 8, a very general power plug 25 is used. Further, the main body side is not subjected to a watertight treatment to prevent water from entering, and the plug receiver 15 is not structured so that water is unlikely to adhere and drainage is easy. Therefore, when supplying water to the container 2 of the main body 1, it is often the case that the main body 1 is poured directly under the faucet of the tap water, and splashed water or overflowed water may adhere to the plug receiver 15. Also, during drainage, water may adhere to the plug receiver 15 depending on the direction of drainage. Furthermore, when washing water stains stuck to the container 2, hold the main body 1 in the sink and wash it by tilting the main body 1 to spill the water in the container 2 or the water collected in the sink adheres to the plug receiver 15. I have something to do.

[0003]

[Problems to be solved by the device]

 As mentioned above, if the magnet plug is inserted and current is applied without wiping off the water that has adhered to the plug receiver, there is a risk of electric shock or a fire accident due to short-circuiting and abnormal overcurrent that continues to generate heat.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and when the water is poured into or drained from the jar pot, the bottom surface of the plug holder is inclined so that water does not accumulate and accumulate on the plug holder. The power plug is equipped with an overcurrent breaker that instantly opens the power circuit even if water adheres or accumulates and short-circuits.

[0005]

[Action]

 With the above configuration, even if water is attached to the plug receiver or if a short circuit occurs, the overcurrent breaker operates and opens the power supply circuit, so it is possible to prevent electric shock, abnormal heat generation, or fire accident. A pot can be provided.

Reference numeral 13 denotes a control means, which is mounted in a substrate case 14 provided in the lower center of the main body 1. Reference numeral 15 denotes a plug receiver fixed to the rear side surface of the bottom frame 16 at the bottom of the main body 1, and an inclined portion 15a inclined outward is provided in the lower inside portion. The bottom surface of the bottom frame 16 is formed without holes. Reference numeral 17 denotes an operation panel which operably blocks operation keys and indicator lamp holes (not shown) provided on the front side surface of the bottom frame 16. A ring-shaped container packing 18 is inserted and fixed between the collar portion 3 of the container 2 and the main body ring 8. A seal packing (1) 19 is inserted and fixed between the outer periphery of the main body ring 8 and the upper portion of the main body 1. Reference numeral 20 denotes a seal packing (2), which is inserted and fixed between the spout main body 9 and the main body 1. A seal packing (3) 21 is inserted and fixed between the body ring 8 and the sprue body 9. 22 is a seal packing (4) which is inserted and fixed between the outer periphery of the upper portion of the bottom frame 16 and the curl portion of the lower portion of the main body 1. Reference numeral 23 denotes a seal packing (5), which is inserted and fixed between the periphery of the mounting hole of the plug receiver 15 provided on the rear side surface of the bottom frame 16 and the plug receiver 15. Reference numeral 24 is a magnet plug, 25 is a power plug, and the magnet plug 24 and the power plug 25 are connected by a cord 27. 26 is a plug blade. Reference numeral 28 is an overcurrent breaker, which is composed of a coil 29 built in the power plug 25, a double-sided switch 30, and a manual return button (not shown). Reference numeral 31 is a terminal to which the magnet plug 24 is connected.

Next, the operation of this embodiment having the above configuration will be described.

Pinch the open / close lever 5 to unlock the lid 4, open the lid 4, fill the container 2 with water, close the lid 4, connect the magnet plug 24 to the plug receiver 15, and connect the power plug. When the plug blade 26 of 25 is inserted into an outlet (not shown) and energized, the heating element 11 and the second main heater 12 are energized, and the information from the temperature detecting means 10 is transmitted to the control means 13 and the control means The function of 13 heats the water and keeps it warm.

When the main body 1 is placed in a place wet with water or the like and the lid 4 is once removed and the main body 1 is turned upside down to discard the residual hot water in a sink or the like, or when the water is made to overflow when supplying water. Even when cleaning the inside of the container 2, a container packing 18 is provided between the collar 3 of the container 2 and the main body ring 8, and a seal packing (1) 19 is provided between the outer peripheral part of the main body ring 8 and the upper part of the main body 1. , The seal packing (2) 20 between the spout body 9 and the body 1, the seal packing (3) 21 between the spout body ring 8 and the sprue body 9, the outer periphery of the upper portion of the bottom frame 16 and the curl portion of the lower portion of the body 1. The seal packing (4) 22 and the seal packing (5) 23 are inserted and fixed between the periphery of the plug receiving hole 15 provided on the rear side surface of the bottom frame 16 and the plug receiving 15 to improve the sealing performance. Since it is kept, it can be used as a mating part of parts It prevents water from entering through the gaps, there is no hole in the bottom frame 16, and an operation nameplate (not shown) is attached to the holes on the operation panel 17 part, and all gaps except the spout 9a are closed. Therefore, the invasion of water into the main body 1 is prevented. Further, since the slanted portion 15a inclined outward is provided at the lower inside of the plug receiver 15, water drops that have entered the plug receiver 15 easily flow, and water drops do not easily accumulate.

However, if water droplets are accumulated and the magnet plug 24 is connected to the plug receiver 15 and electricity is applied, a short circuit occurs between the terminals 31 and an overcurrent flows. At this moment, an overcurrent flows through the coil 29 of the overcurrent breaker 28, and the switch 30 is switched from the a side to the b side in an interlocked manner to instantly open the circuit, and the current after that is cut off. Therefore, the magnet plug 24 And wipe the water drops on the plug receiver 15 cleanly, then press the manual return button (not shown) to switch the switch 30 from the side b to the side b and connect the magnet plug 24 to the plug receiver 15 again to use electricity. You can Since the switch 30 is cut into both sides, even if there is welding of the contacts, the circuit is always opened so that safety is further enhanced.

[0012]

[Effect of the device]

 As described above, according to the present invention, when water is drained from a container, when cleaning, or during use, water drops adhere to the plug receiver, and if water drops are collected, connect the magnet plug to the plug receiver and connect the power supply. When the plug is plugged into a power outlet and energized, a short circuit occurs between the terminals, causing an overcurrent to flow, but the overcurrent breaker operates and the circuit is opened by a double-sided switch in the power plug, which cuts off the current flow and electric shock It is possible to prevent abnormal heat generation and fire accidents. If you want to turn the power on again, you can reuse it by pressing the manual return button.

In this way, it is possible to provide a highly safe jar pot that takes into consideration an emergency.
