Abstract

PURPOSE:To prevent a water feeder from being erroneously driven by an operator when a base temperature is low by changing display at the time of setting dry and at the time of setting steam, and changing the display, when the base temperature is within the proper temperature for generating the steam at the time of setting the steam, and when the base temperature is out of the proper temperature for generating the steam, on a steam displaying section. CONSTITUTION:When the temperature of a base 1 is out of a proper temperature for generating steam and when a steam button 9 is operated, then by the LED of said steam displaying section 12, lighting and extinction are repeated in a constant period. Accordingly, a worker can visually recognize that the temperature of the base 1 is not a proper temperature for generating the steam. Besides, when the base 1 is heated by a heater 2 and the temperature of the base 1 is heightened to the range of the proper temperature for generating the steam, then the LED of the steam displaying section 12 is changed to be continuously lit. Accordingly, the worker can understand that the temperature of the base 1 is heightened to a temperature for enabling the steam to be generated, and ironing with the steam can be performed. As a result, water can be prevented from leaking out of the base in error, and fibers or the like can be prevented from being stained.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a household steam iron for removing wrinkles from clothing and the like.

Conventional technology Conventionally, this type of steam iron has a water supply device that supplies water in a tank to a vaporizing chamber in a base, a steam button that excites the operation of this water supply device, and a steam display formed by one LED. As shown in FIG. 4, when the steam button is operated and the water supply device is in the driving state, the LED of the steam display section lights up, and the water supply device is in the stopped state. It was common for the lights to go out at certain times.

Problems to be Solved by the Invention However, with this configuration, the water supply device is activated by operating the steam button regardless of the temperature of the pump, and the LED in the steam display section is turned on, making it difficult to work. The operator may be unable to determine whether the pace temperature has reached a temperature suitable for steam generation, and may accidentally operate the water supply device when the pace temperature is too low to generate steam. , there was a problem that water leaked from the base, resulting in stains on the fibers.

Therefore, the present invention uses a steam display to display whether or not the base temperature has reached the appropriate temperature range for steam generation when setting the steam, thereby preventing the operator from accidentally operating the water supply device when the base temperature is low. It is intended to.

Means for Solving the Problems And in order to achieve the above object, the present invention uses a steam display section to change the display depending on when the base temperature is within the appropriate temperature range for steam generation and when it is outside the appropriate temperature range for steam generation when setting the steam. This is how it was done.

Function: Due to the above structure of the steam iron of the present invention, it is clear from the steam display section whether the base temperature is within the appropriate temperature range for steam generation or outside the appropriate temperature range, so if the operator mistakenly causes the base temperature to be low, the water supply can be stopped. Water leakage caused by driving the device can be prevented.

EMBODIMENT MU Below, one embodiment of the present invention will be described based on the accompanying drawings. @1 In the figure, 1 is the base with heater 2 3
4 is a tank for storing water to be supplied to the vaporization chamber 3; and 5 is a water supply device composed of a motor or a renoid for feeding the water in the tank 4 to the vaporization chamber 3. It has a water suction pipe 7 for sucking water 6 in the tank 4 and a discharge pipe 8 for sending it to the vaporization chamber 3.

Reference numeral 9 indicates an automatic return type steam button for starting the water supply device 6, and 1Q indicates the operation of the water supply device 6 and the base 1.
It is a control means that controls the temperature of the base 1 in response to the output of a temperature detection means 11 such as a thermistor attached to the base 1, and is composed of a plurality of electronic components. Reference numeral 12 denotes a steam display section, which is composed of one LED.

To explain the operation in the above configuration, as shown in FIG.
Since the LED is in a blinking state that repeatedly turns on and off at regular intervals, the operator can visually recognize that the temperature of the base 1 is in a temperature range inappropriate for steam generation. Furthermore, when the υ pace 1 is heated by the heater 2 and the temperature of the base 1 rises to within the appropriate temperature range for steam generation, the LED of the steam display section 12 changes to a continuous lighting state. Once the temperature has risen to a level where steam can be generated, ironing with steam can be performed. If the water supply device 5 is driven in this state and ironing is continued while blowing out steam, the temperature of the base 1 may be deprived of heat by the water 6 and fall below the appropriate temperature range for steam generation.

In this case, in the above configuration of the present invention, the LED of the steam display section 12 which has been in a continuously lit state changes to a blinking state, so that the operator can recognize that the temperature of the base 1 has decreased, and the steam button 9 can be operated to stop the water supply device 6, thereby making it possible to prevent water from leaking from the base 1. Further, when the steam button 9 is not operated, that is, when ironing is performed in a dry state without driving the water supply device 6, the steam display section 12
Since the LED remains off, the operator can determine whether the water supply device 6 is stopped (dry setting) or driven (steam setting). As mentioned above, the temperature status of the base 1 can be visually confirmed using the steam display, which prevents water from accidentally leaking from the base 1 and staining the fibers. Become.

FIG. 3 shows another embodiment, in which the base temperature and the water supply device are made responsive. In this case, if you operate the steam button once and set the steam setting, if the base temperature is outside the appropriate temperature range for steam generation, the LED in the steam display will blink as shown in Figure 2, but the water supply device will be in a stopped state. hold.

When the base temperature rises and reaches the appropriate temperature range for steam generation, the water supply device automatically starts driving and the LED of the steam display section becomes continuous.

Furthermore, even if the base temperature falls outside the steam generation appropriate temperature range during ironing, the LED of the steam display changes to a blinking display and at the same time the water supply device stops driving. Therefore, the water supply device automatically operates only when the temperature is suitable for steam generation, which prevents water from leaking from the base, while also eliminating the need to frequently operate the steam button, further improving usability. It is something to do.

Effects of the Invention As described above, in the present invention, since the display is different depending on whether the base temperature is within the appropriate temperature range for steam generation or when it is outside the appropriate temperature range, it is possible to visually determine whether the base temperature is within the appropriate temperature range for steam generation or outside the appropriate temperature range. 9, which can prevent water from accidentally leaking from the base and staining fibers, etc.
