[Technical background of the invention and its problems]

A boiling water pot is a device that can be used to pour hot water that has been heated to a boiling point as needed.A boiling heater is attached to a cylindrical tank with a bottom, and the tank is housed in a case. An inner stopper is attached to the opening at the top end to seal the tank, a ventilation hole is formed in the inner stopper, a rotatable top cover is provided at the top end of the case, and an air pump mechanism is assembled inside the top cover. It gets crowded. Then, water is stored in the tank and heated to a boiling point with a boiling heater to bring it to a high temperature. In this state, the air pump mechanism is operated and compressed air is passed through the inner stopper. The hot water is forced into the tank through the pores, pressurizes the surface of the hot water, and pours out the hot water.

The pressure inside the tank is high due to steam from boiling water, so a steam release path is provided in the top lid, and the steam inside the tank is allowed to flow out little by little from the vent hole in the inner stopper to the outside through this steam release path. Prevents abnormally high pressure.

However, when refilling water in the tank,
When the top cover is rotated to stand up, the steam escape path becomes vertical or nearly vertical.
As a result, there has been a problem in that the condensed water of the steam remaining in the steam escape passage flows out of the upper cover through the steam escape passage, drips onto the floor, and wets the floor.

[Purpose of the invention]

This invention was made with attention to these points, and its purpose is to provide a water boiling pot that prevents steam condensed water from accidentally flowing out and dripping from the steam escape path. It's about doing.

[Summary of the invention]

That is, this invention has a top lid rotatably attached to the upper end of a case housing a water boiling tank,
The upper lid is provided with a steam escape passage for allowing the steam in the tank to flow out to the outside, and the tip of the steam relief passage is made to face near the pivoting part of the upper lid, and the upper lid is attached to the tip. When the steam condensed water in the steam relief path flows toward the pivot part of the upper lid when the steam condensed water is rotated to a state where it is almost upright, a receiving part having a certain depth is provided to receive and store the condensed water. This is how it was done.

An operating body 25 is provided in the recess 9 of the upper lid 8 so as to be movable up and down, and this operating body 25 is connected to the upper end of the shaft 24 via a spring 26. A sealing collar 27 is provided to airtightly seal the intake hole 23 as the body 25 descends.

Inside the relay body 14, as shown in detail in FIG. A sealing valve 32 is provided so that ventilation is always possible. This sealing valve 32 consists of a cylindrical part 33 and a flange part 34, and the cylindrical part 33 is loosely inserted into the discharge port 21 of the bellows 20.
The flange portion 34 is arranged so as to come into contact with the periphery of the discharge port 21. An opening/closing hole 35 is formed in the center of the upper wall of the shutoff valve 30, and a screw 36 is loosely inserted into the opening/closing hole 35 from the inside of the shutoff valve 30, and then the shutoff valve 30 is inserted into the opening/closing hole 35.

The upper lid 8 is provided with a steam pipe 40, and the steam pipe 40 is made of a metal material, for example, stainless steel, and has an arc-shaped cross section and a gutter-like shape as a whole, and has a collar 41 on the side edge. ,41
It is constructed by forming a pair of divided parts 42, 42 which integrally have the parts 42, 42, and butting the flanges 41, 41 of these divided parts 42, 42 against each other. On the upper side of this steam pipe 40 is a substrate 10 of the upper lid 8.
A fixing plate 44 attached to the upper lid 8 is disposed on the lower side, and a recess 45 and a flange 41 having an arcuate cross section corresponding to the outer circumferential curved shape of the steam pipe 40 are disposed on the base plate 10 and the fixing plate 44. , 41 is formed with a groove 46 corresponding to the shape of the abutted portion. Then, the recess 45 of the base plate 10 is tightly fitted to the upper circumferential surface of the steam pipe 40, the flanges 41, 41 of that part are tightly fitted to the groove 46, and the recess 45 of the fixed plate 44 is also fitted tightly to the upper peripheral surface of the steam pipe 40. It fits closely to the lower circumferential surface of the pipe 40, and the flanges 41, 41 of that part fit tightly into the groove 46, so that both the divided parts 42, 42 are firmly connected and integrally formed. It is assembled as a steam pipe 40. The base end of the steam pipe 40 is connected to the connection port 15 of the relay body 14 as an inflow port 47, and the tip end is connected to the connection port 15 of the relay body 14 as an outflow port 48. A cylindrical water receiving member 49 made of rubber or plastic is connected, and the outlet 48 is connected to a steam port 50 on the wall of the top cover 8 through the water receiving member 49, thereby connecting the ventilation hole 16 to the top cover. A steam escape path 51 communicating with the outside of 8 is configured. A bag-shaped receiving portion 52 having a certain depth is integrally formed in a part of the peripheral wall of the water receiving member 49. Further, a branch passage 53 is formed in the middle of the steam pipe 40, and a boiling control thermosensor 54 is provided on the end face of this branch passage 53.

On the other hand, a thermosensor 55 for sensing hot water temperature and a limiter 56 for sensing abnormal temperature are provided at the middle of the outer periphery of the tank 2, and a thermosensor 57 for controlling heat retention is provided at the outer bottom of the tank 2, respectively. Note that 58 is a lock mechanism that seals the top cover 8 to the case 1, 59 is an operation button for releasing the lock mechanism, and 60 is a plug holder.

However, when the lock mechanism 58 is removed and the top cover 8 is rotated upward about the hinge pin 7, the inner stopper 11, which is integral with the top cover 8, is separated from the opening at the top end of the tank 2, and the opening is opened. In this state, water is stored in the tank 2, and then the top lid 8 is closed again and a boil button (not shown) is operated. In response to this, the boiling heater 3 and the heat-retaining heater 4 are energized, and the water in the tank 2 is heated, and the water is brought to a boiling state. Then, the steam from this hot water passes through the steam escape path 51 from the vent hole 16 and flows out little by little from the steam port 50 to the outside, thereby preventing abnormally high pressure inside the tank 2, and part of the steam is branched out. Based on this, the boiling control thermosensor 54 detects the boiling state of the water in the tank 2, and in response to this detection, the boiling heater 3 is de-energized, and only the heat-retaining heater 4 is turned off. Thereafter, the thermosensor 57 for heat retention control controls the energization of the heat retention heater 4, and the hot water in the tank 2 is kept at a high temperature close to a boiling state.

Here, when the operating body 25 is pressed, the cutoff valve 30 comes into contact with the surface around the ventilation hole 16, as described above, and therefore the ventilation hole 16 and the steam escape passage 5 are brought into contact with each other.
1 is cut off, and in this state, the compressed air in the bellows 20 is sent into the tank 2, the liquid level of the hot water is pressurized, and the hot water flows into the spout passage 5.
The liquid is poured out through the spout 6. In this way, the high temperature hot water in the tank 2 can be taken out in appropriate amounts at a time.

In addition, when the above-mentioned boiling button is operated again, the boiling heater 3 is energized again via the boiling control thermosensor 54 as described above, and the hot water in the tank 2 is temporarily brought to a boiling state. By operating the operating body 25 under this condition, the boiling water can be taken out.

Under such conditions, in order to replenish water into the tank 2, etc., the top cover 8 is rotated upward about the hinge pin 7 to almost stand up, as shown by the chain line in FIG. And, along with this, the steam escape path 51
The condensed water remaining inside flows to the pivoting side of the upper lid 8. However, a bag-shaped receiving part 52 is provided at the tip of the steam escape passage 51, and therefore, the condensed water flows into this receiving part 52 and is stored. This prevents the inconvenience of dripping and getting the floor wet.

In addition, in the above embodiment, the steam pipe 40
Although the water receiving member 49 is connected to the water receiving member 41 and the condensed water receiving portion 52 is formed in the water receiving member 41, the structure is not limited to this. There is no problem with integrally forming a receiving part that allows the upper lid to stand up when the upper lid is rotated to an almost erect position. What is necessary is to provide a receiving portion having a certain depth that can receive and store condensed water in the steam escape passage.

〔Effect of the invention〕

As explained above, according to the present invention, since a receiving part capable of storing condensed water is provided at the tip of the steam escape passage, when the top cover is rotated to almost stand up, condensed water remains in the steam escape passage. The condensed water flowing through the steam vent can flow into the receiving part and be stored therein, which eliminates the inconvenience of condensed water dripping from the steam escape passage and wetting the floor, improving usability. play.
