Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ironing device for removing wrinkles from clothing.

2. Description of the Related Art Conventionally, this type of ironing device has been disclosed, for example, in Japanese Patent Application Laid-Open No. 58-2
The structure was as shown in Japanese Patent No. 9498, and specifically, the structure was as shown in FIG.

That is, a stand 1 is provided with a water tank 2 and a mounting section 3,
Water was supplied into the iron body 4 by placing the iron body 4 on the above-mentioned placement part 3.

Problems to be Solved by the Invention However, with such a structure, the iron body 4 and the water tank 2 are connected to each other, and the water head pressure of the water tank 2 is used to supply water to the iron body. 4, there was a problem that the time required to supply a predetermined amount of water was not constant.

In other words, as the water level in the water tank 2 changes, the water head pressure also changes, and as a result, the water supply rate also changes.

In addition, as a means to solve such problems, a method of forcibly supplying water using a water supply device such as a pump device can be considered, but when the tank of the iron main body 4 becomes full of water,
There was a problem in that water leaked from the connection between the water inlet 5 of the iron main body 4 and the water inlet 6 projected onto the placement part 3 of the stand 1.

Moreover, if the water supply device continues to operate even when the water supply device is full of water, not only will the water supply device be overloaded, but there is also a risk of damage to the connection parts, seals, etc.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an ironing device that is easy to use and can prevent water from leaking from the water supply port and can supply water to the iron body in a simple manner.

Means for Solving the Problems And in order to achieve the above object, the present invention provides a water amount detection means for detecting the water amount in the tank of the iron body, and also detects the amount of water in the tank of the iron body by this water amount detection means. When the amount of water in the tank is less than a predetermined amount, the water supply device is actuated to supply water up to the predetermined amount of water in the tank.

Function: With the above configuration, the ironing device of the present invention is configured such that when the water level in the tank inside the iron body decreases during use, the water level detection means detects this and can supply water up to a specified amount when placed on the stand. At the same time, the water supply can be stopped when the tank becomes full.

In other words, each time the iron body is placed on the stand during a short break during ironing, the amount of water consumed during ironing is replenished each time.

Therefore, since the amount of water in the tank is always constant, a stable amount of steam is emitted, making ironing work smoother.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 10 denotes an iron body, a base 13 forming a vaporization chamber 12 covered with a lid 11, a heater 14 for heating the base 13, and temperature detection means such as a thermistor for detecting the temperature of the base 13. 15, the vaporization chamber 1

Water amount detection means 19 and temperature detection means 15 provided in 7.
Temperature signal processing means 2 constituted by a plurality of electronic components that processes the output signal of and outputs it to a signal terminal (not shown).
1. It has a power supply bin 22 connected to the heater 14.

Reference numeral 23 denotes a stand, which includes a plurality of power supply terminals 24 each connected to the signal terminal of the iron body 10 and the power supply bottle 22, a water supply valve device 25, a water storage tank 26 for storing water, and the water stored in the water storage tank 26 is transferred to the tank. a water supply device 27 composed of a pump or the like, for supplying water to the heater 14; Control means 28 constituted by parts;
3, a temperature setting means 29 for setting the iron body 10 to a desired temperature, a set temperature display means 30 for displaying the set temperature state with an LED or the like, and a mounting device for tilting the iron main body 10 with the base 13 facing downward. It has a section 31.

Next, the operation of the configuration of this embodiment will be explained. First, when ironing, place the iron main body 10 on the placement part 31 of the stand 23, turn on the power, and operate the temperature setting means 29 of the stand 23 to set the base 13 to a desired temperature. In response to the output of the temperature detection means 15, the temperature signal processing means 21 outputs a signal to the control means 28 via the signal terminal. In response to this signal, heater 1
4 is supplied with power to the power supply bin 22.4. This is done via the power supply terminal 24, and the base 13 rises to the set temperature. Further, when the power is turned on, the control means 28 starts operating, and the water supply device 27 is driven at the same time. When the iron main body 10 is placed on the stand 23 as described above, water in the water storage tank 26 is sent to the tank 17 through the inlet 18 by the water supply device 27.

Here, when the iron main body 10 is removed from the mounting part 31 and ironing is performed, the water in the tank 17 is drained from the water conduit 16.
It is sent to the vaporization chamber 12 through the vaporization chamber 12, vaporized in the vaporization chamber 12, and ejected from the bottom surface of the base 13 as steam.

Next, when the iron main body 10 is placed on the inclined mounting portion 31, the signal terminal and power supply bottle 22 are connected to the power supply terminal 24, and the heater 14 is energized.

In FIG. 2, the water amount detection means 19 is provided with a photo-sobber 19a placed opposite the specified full water position of the tank 17, and inside the tank 17 there is a ball 1 floating on the water surface.
9b is the insert. If the water in the tank 17 is less than the specified amount as shown in A, the ball 19b is connected to the photocoupler 1.
Since the light from the LED 9a is not blocked, the control means 28 determines that the amount of water is low and drives the water supply means 27 to supply water. Then, when the hole 19b rises due to water supply and the LED light is blocked by facing the photocoupler 19a as shown in B, it is detected that the water is full and the drive of the water supply device 27 is stopped, and a predetermined amount of water is Water can be supplied.

In addition, in the above embodiment, water is supplied by detecting that the amount of water in the tank 17 has fallen below a predetermined amount;
A water amount detection means may be provided at the bottom of the tank to detect when the water in the tank has run out. In this case, a predetermined amount of water can be supplied into the tank by driving the water supply device for a certain period of time after the water amount detection means is activated.

In addition, we used a photocoupler to detect the amount of water, but we also used electrodes and capacitance.

It is also possible to use a piezoelectric element or the like. In short, any device that can control the water supply device by detecting changes in the amount of water in the tank within the iron body is sufficient.

Effects of the Invention As described above, the present invention detects the amount of water in the tank of the iron body, and when the amount of water in the tank is less than a predetermined amount, drives the water supply device to supply water to the specified amount in the tank. By supplying water, the amount of water consumed during ironing can be replenished each time the iron body is placed on the stand during a short break during ironing work.

Therefore, by reducing the capacity of the tank, the weight and size of the iron body can be reduced, and the amount of water in the tank can always be kept constant to eject stable steam.

Moreover, it is possible to obtain an ironing device that is safe and easy to use by preventing overloading of the water supply device and improving its durability, and also preventing water leakage from the connecting portion.
