Description

  TECHNICAL FIELD The present invention relates to a steam sprayer that wrinkles and stretches clothes and the like.

  In a conventional steam sprayer, water stored in a water tank is sent to a vaporization chamber by a pump device, and vaporized steam is sprayed. By using a pump device for water supply to the vaporization chamber, it is possible to eliminate the restriction due to gravity in the water supply direction. Thereby, the user can eject the steam by directing the steam ejector in any direction to the clothes etc. in a state of being hung on the hanger. If water is supplied when the vaporization chamber is not heated to a temperature at which the water can be vaporized, the non-vaporized water spouts out together with the steam, causing a problem of wetting clothes and the like. For this reason, the water supplied to the vaporization chamber needs to be vaporized instantly.

  In order to solve such a problem, there is a steam jet that makes it possible to drive an electric pump when the vaporization chamber is heated to the temperature at which water can be vaporized. By using an electric pump for supplying water to the vaporization chamber, a manual operation at the time of spouting steam can be simplified and usability can be improved (see, for example, Patent Document 1).

  In addition, there is a steam iron configured to control the water supply device by selecting each state of steam, increase steam, and steam stop, each time the steam selection button configured by the switch is pressed. Since the setting of the steam state is performed by the same operation of pressing the steam selection button, the LED is displayed so that the state of the set steam can be known. In addition to a plurality of displays provided corresponding to the state of steam to be set, when it is performed with one display, it is normally lit during steam, blinks during increased steam, and extinguished when steam is stopped ( See, for example, Patent Document 2).

  In addition, there is a steam iron configured such that the amount of steam can be varied by duty control of an electric pump that supplies water of a water tank to a vaporization chamber (see, for example, Patent Document 3).

The electric pump is driven based on the above, and the first signal and the second signal are outputted by one of the operation parts, and the second signal is manually operated different from the operation of outputting the first signal. Is output Those configured to.

  As a result, a steam ejector equipped with a steam increasing mechanism can be realized without losing convenience due to an increase in the size or weight of the shape, and a steam effect such as wrinkle extension by the increased steam can be enhanced. .

  The steam sprayer of the present invention can enhance the wrinkle straightening effect of the additional steam without losing the usability.

The amount of water stored in the water tank 20 is configured to be visible by a transparent display window 23 formed elongated in the vertical direction.

An electric pump 24 for supplying water in the water tank 20 to the vaporization chamber 1 is disposed adjacent to the rear of the water tank 20 and is attached to a pump support 25 formed on the heat insulator 16. The pump support 25 is provided above the heat insulator 16. The heat insulation space formed between the upper surface of the heat insulator 16 and the pump support 25 prevents the electric pump 24 from overheating.

The reciprocation of the plunger mechanism of the electric pump 24 sucks the water in the water tank 20 through the water absorption pipe 26, and the water is discharged to the vaporization chamber 1 through the water transmission pipe 29.

  The control unit 30 has a control circuit configured on a printed circuit board and is provided in the handle unit 18. The control unit 30 controls the temperature of the vaporization chamber 1 in the vicinity of the inner side of the curved portion 2a of the heater 2 to a predetermined temperature at which water can be vaporized (for example, , 150 ° C.). At the front of the lower surface of the handle portion 18, a pump switch 31 is provided as an operating portion for manually operating the drive of the electric pump 24. The control unit 30 is configured to drive the electric pump 24 based on a signal output by manual operation of the pump switch 31.

  When the pump switch 31 is not pressed, it is in the off state, and the electric pump 24 is not driven. The first signal for supplying the amount of water for generating steady steam to the vaporization chamber 1 by the on (pressing) operation of the pump switch 31 is output, and the control unit 30 drives the electric pump 24 based on the input first signal. And the amount of water set as steady steam (for example, 0.2 g / sec) is supplied. Steady-state steam can be used at any time by turning on the pump switch 31, and can be continuously jetted by keeping it pressed. The pump switch 31 may be configured to lock in a pressed state. In this case, since the pressed state is held until the lock is released, the burden on the finger pressing the pump switch 31 is reduced. be able to.

  In addition, it is possible to increase the amount of steam more than steady steam. The manual operation of the pump switch 31 outputs a second signal for supplying the amount of water for temporarily generating the increase steam to the vaporization chamber 1. The control unit 30 drives the electric pump 24 based on the input second signal, and the water amount (for example, 0.6 g / sec) set to about three times the steady state steam is supplied. The second signal is output by a manual operation different from the operation of outputting the first signal. For example, while the first signal is output when the pump switch 31 is turned on, the second signal is output when switched on several times (for example, twice pressed). That is, one pump switch 31 is configured to be able to selectively output different signals (a first signal for steady steam generation and a second signal for increase steam generation).

Since a large amount of water is temporarily supplied to the vaporization chamber 1 as the increase steam, when the second signal for generating the increase steam is output, the control unit 30 sets the electric pump 24 for a short time (for example, 1 second) B) driving and stopping, suppressing a rapid temperature drop of the vaporization chamber 1 to maintain a temperature at which steady steam can be generated. If the output signal of the temperature sensing unit 11 is input to the control unit 30 that the vaporization chamber 1 is heated to the settable temperature of water when the pump switch 31 is turned on during use. The electric pump 24 is driven to send a set amount of water to the vaporization chamber 1 to eject steam.

  The control unit 30 sets the amount of water supplied to the vaporization chamber 1 by the electric pump 24 to be equal to or less than the vaporization capacity of the vaporization chamber 1, and the amount of water supplied to the vaporization chamber 1 is equal to or less than the vaporization capacity of the vaporization chamber 1 24 is configured to drive. The vaporization capacity is a state in which the water supplied to the vaporization chamber 1 can be vaporized instantly, and the supplied water is vaporized instantly and spouted from the steam jet port 9. The vaporization capacity is determined by the temperature of the vaporization chamber 1, the surface area in contact with the supplied water, the amount of heat, and the like, and the vaporization capacity can be prevented by exceeding the amount of water supply.

  The control unit 30 duty controls, for example, the drive of the electric pump 24 so that the amount of water set for each of the steady steam and the additional steam is supplied to the vaporization chamber 1. When the control unit 30 detects that the vaporization chamber 1 is not heated to the set temperature by the temperature sensing unit 11, the control unit 30 does not drive the electric pump 24 even when the pump switch 31 is turned on. As a result, the control unit 30 can prevent water supply to the low temperature vaporization chamber 1 and prevent the water from leaking out from the steam jet nozzle 9 without being vaporized.

  With these configurations, the user grips the handle portion 18 and moves the housing 17 with respect to clothes etc., while the manual operation of the pump switch 31 increases the amount of steam in addition to the spouting and stopping of steady steam. It is easy to operate the steam. The state of steam set by the pump switch 31 is displayed by the display units 34 and 35 configured by LEDs. The display portions 34 and 35 are provided on the front of the upper surface of the handle portion 18 which can be viewed in a state in which the handle portion 18 is gripped by hand.

  In addition to the vaporization body 3 in which the vaporization chamber 1 was formed, the water tank 20, and the electric pump 24, the power switch 32 is provided in the inside of the housing | casing 17. As shown in FIG. The power switch 32 is attached to a support (not shown) provided on the heat insulator 16. The power switch 32 is configured as a slide switch, and the power switch 32 is turned on / off by manual operation of the switch button 33 provided on the outer surface of the housing 17.

  When power is turned on by the power switch 32, the display unit 34 (LED 1) blinks in red, and when the vaporization chamber 1 rises to a predetermined temperature T1 (for example, 120 ° C.), it lights in red and steady steam can be used Show that there is. When the display unit 34 (LED 1) is lit, steady-state steam can be ejected by turning on the pump switch 31 at any time. The display unit 35 (LED 2) lights up in red when the vaporizing chamber 1 rises to a predetermined temperature T2 (for example, 150 ° C.), and indicates that use of the increased steam is possible.

  Commercial power is supplied to the heater 2 from a power cord 36 drawn rearward from the rear of the housing 17. The power cord 36 is protected at the exit from the housing 17 by a flexible protector 37 formed of a flexible tube. The steam ejector according to the present embodiment is configured to be mounted on the stand 38 with the press surface 4c of the base 4 facing downward when not in use and when not in use.

  The operation and operation of the steam jet apparatus configured as described above will be described below.

  The user places a predetermined amount of water in the water tank 20 and places it on the stand 38, and operates the switch button 33 to turn on the power switch 32. As a result, the heater 2 is energized, and the display unit 34 (LED 1) blinks in red to indicate that the temperature of the vaporization chamber 1 is rising. When the vaporization chamber 1 is heated by the heater 2, the temperature sensing unit 11 senses the temperature of the vaporization body 3, and the output signal thereof is input to the control unit 30.

  When a predetermined time t1 (for example, about 30 seconds) elapses after the start of energization of the heater 2, the vaporization chamber 1 reaches a predetermined temperature T1 (for example, about 120 ° C.) (D part in FIG. 9). Then, the display unit 34 (LED 1) changes from blinking to lighting to indicate that steady steam can be used. Here, when the user turns on (presses) the pump switch 31, a first signal for supplying the amount of water for generating steady-state steam to the vaporization chamber 1 is output, and the control unit 30 outputs the first signal. The electric pump 24 is driven based on the set amount of water (for example, 0.2 g / second) to be supplied.

  The steady-state steam can be used as needed by turning on the pump switch 31 when the display unit 34 (LED 1) is lit, and can be continuously jetted by keeping it pressed. The temperature of the vaporization chamber 1 rises while using steady steam, and when the steady steam is used for a predetermined time t2 (for example, about 10 seconds) from the time when the predetermined time t1 elapses, the vaporization chamber 1 has a predetermined temperature T2 (for example, It reaches about 150 ° C. (E part in FIG. 9). Then, in addition to the lighting state of the display unit 34 (LED 1), the display unit 35 (LED 2) also lights in red, indicating that the use of the increase steam is possible.

  Here, if the user performs a plurality of intermittent on (for example, twice pressing) operations different from the manual operation at the time of steady steam, the user supplies the amount of water for generating the increased steam to the vaporization chamber 1 Signal is output. The plurality of intermittent ON operations is that the plurality of ON operations are intermittently performed within several seconds (for example, 2 to 3 seconds). In this way, the second signal is identified by a manual operation different from the on operation where the first signal is output. The control unit 30 drives the electric pump 24 based on the input second signal. Then, a water amount (for example, 0.6 g / second) set to about three times the steady-state steam is supplied.

  The additional steam temporarily supplies a larger amount of water to the vaporization chamber 1 than the steady steam. For this reason, when the second signal for generating the increase steam is output, the control unit 30 drives the electric pump 24 for a short time (for example, 1 second) and stops it, thereby suppressing the rapid temperature drop of the vaporization chamber 1 And maintain the temperature at which steady steam can be generated. When the increase steam is used, the display unit 35 (LED 2) is turned off and lights up again after a predetermined time t3 (for example, 10 seconds) for the temperature of the vaporization chamber 1 to recover, indicating that use of the increase steam is possible. Do. The relighting of the display unit 35 (LED 2) may be performed based on the output signal of the temperature sensing unit 11. The display unit 34 (LED 1) temporarily turns off after the increase steam is used, and lights up to indicate that steady steam can be used.

  When the user turns on the power switch 32 in order to use the steam jet, in most cases, the water pipe 29 from the water tank 20 to the vaporization chamber 1 is empty. For this reason, in the first water supply which is used every time, the electric pump 24 supplies water to the vaporization chamber 1 after the water supply pipe 29 is filled with water. That is, water is not supplied to the vaporizing chamber 1 immediately after the pump switch 31 is turned on, and steam is not generated in the initial short time. After the second on-operation, steam is generated immediately after the on-operation of the pump switch 31 since water is supplied immediately to the vaporization chamber 1.

  Because of this, even if a plurality of intermittent ON operations are performed at the beginning of use and the second signal for generating the additional steam is output and the electric pump 24 is driven for a short time (for example, 1 second) The steam is not generated only by filling the water pipe 29 with water. For this reason, the control unit 30 can drive the electric pump 24 based on the second signal to be the increase steam after driving the electric pump 24 for a predetermined time (t2) based on the first signal to be the steady steam. It is configured. Thereby, since water is filled in the water pipe 29 for transferring water from the water tank 20 to the vaporization chamber 1 by use of the steady steam, it is possible to prevent the problem that the steam is not spouted when using the additional steam.

  The control unit 30 controls on / off of the heater 2 based on the output signal from the temperature sensing unit 11 so that the portion where the water is supplied to the vaporization chamber 1 is maintained at a predetermined temperature. When steam is not used, there is no water supply to the vaporization chamber 1, and no heat is lost to vaporization of water, so the temperature is controlled to a set temperature with a predetermined width (F in FIG. 9). During this time, when the second signal is output by the pump switch 31 when the heater 2 is in the off state, the heater 2 is in the energized state to suppress the temperature drop (part G in FIG. 9).

  The control unit 30 controls the driving of the electric pump 24 based on the output signal of the temperature sensing unit 11. Then, when the vaporization chamber 1 is not heated to a predetermined temperature, the electric pump 24 is not driven. As a result, even when the pump switch 31 is operated when the vaporization chamber 1 is not heated to the temperature at which water can be vaporized at the start of use, the electric pump 24 is not driven and the evaporation chamber 1 is Water supply can be prevented.

  A water supply port 10 is provided opposite to the inner vicinity of the curved portion 2 a of the heater 2. The water supplied from the water supply port 10 is vaporized in the portion of the vaporization chamber 1 which is heated to the earliest predetermined temperature. Further, the temperature sensing portion 11 is provided in proximity to the outside of the curved portion 2 a of the heater 2 having the fastest temperature rise. As a result, the temperature sensing unit 11 can quickly and accurately detect the temperature of the portion where the water is supplied to the vaporization chamber 1, and can detect that the temperature has reached a predetermined temperature. Therefore, the waiting time until the temperature reaches the predetermined usable temperature at the start of use is reduced, and the work can be started quickly.

  In addition, when the electric pump 24 is driven based on the first signal or the second signal output by the manual operation of the pump switch 31 and a predetermined amount of water is supplied to the vaporization chamber 1, The portion to which water is supplied, that is, the vicinity of the inside of the curved portion 2a of the heater 2 loses heat due to the vaporization of the water and the temperature drops. At this time, the temperature sensing unit 11 senses temperature drop with high sensitivity and outputs a signal. The control unit 30 can quickly energize the heater 2 in response to the output signal of the temperature sensing unit 11, maintain the set temperature, and stabilize the jet of steam.

  And when the temperature sensing part 11 is provided in the hollow part 13 provided so that it might surround with the rib 14 in the outer side of the curved part 2a, the sensitivity which detects the temperature fall of the vaporization chamber 1 can be raised further. When the hollow portion 13 is provided outside the curved portion 2a, the heat capacity of the portion where the curved portion 2a of the vaporizer 3 is embedded is reduced, and the temperature decrease is accelerated. For this reason, the control unit 30 can quickly detect the temperature decrease by the temperature sensing unit 11 and can maintain the temperature of the vaporization chamber 1 with high accuracy by energizing the heater 2. Also, when the rib 14 is formed on the outside of the hollow portion 13 toward the rear end 4b of the base 4, the rear end 4b is used by providing a heat transfer function to the rear end 4b when used as an iron. Can improve the wrinkles straightening effect.

  The steam generated in the vaporization chamber 1 fills the steam passage 5 through the bent passage 8 and the communication portion 7 formed on the heater 2, and spouts from the steam jet port 9. The steam in the steam passage 5 is also in contact with the lower cavity 15 recessed on the base 4 side of the vaporizer 3. Therefore, in the portion where the curved portion 2 a of the heater 2 of the vaporizing body 3 is embedded, the hollow portion 13 formed on the upper surface side of the vaporizing body 3 and the lower hollow portion 15 formed on the lower surface side of the vaporizing body 3 The heat capacity is reduced at both. Thereby, the control unit 30 can detect the temperature decrease due to the vaporization of the water with high sensitivity in the temperature sensing unit 11.

  Further, since the amount of water supplied to the vaporization chamber 1 by the electric pump 24 is set equal to or less than the vaporization capacity of the vaporization chamber 1, water is not excessively supplied to the vaporization chamber 1 and the steam is stably ejected. It can be done. As a result, it is possible to prevent the interruption of work due to the temperature decrease of the vaporization chamber 1.

  When the user stretches the wrinkles of clothes etc. hung on the hanger, as shown in FIG. 10, the press surface 4c of the base 4 is substantially vertical (substantially vertical) toward the object H for stretching the wrinkles of clothes etc. The press surface 4c jets steam from a position away from the clothes or the like. By supplying the steam in this manner, the steam effect can be exhibited by steaming without pressurizing the clothes or the like, and wrinkles can be straightened and deodorized. When used as a steamer, steam is supplied while moving a wide range of clothes and the like. For this reason, the attitude | position at the time of holding | gripping with the handle part 18 always changes, and the water in the water tank 20 also moves by gravity simultaneously. The water absorption pipe 26 connected to the electric pump 24 is displaceable in the direction of gravity along with the movement of the water in the water tank 20 according to the change of the posture at the time of use, when the water in the water tank 20 becomes small. However, the submerged condition is maintained and steam can be jetted.

  The electric pump 24 may be a centrifugal pump or the like, as long as it is electrically driven and can set the water supply amount.

  As described above, the steam jet apparatus according to the present embodiment includes the vaporization chamber 1 for steam generation, the heater 2 for heating the vaporization chamber 1, and the water tank 20 for storing water supplied to the vaporization chamber 1. An electric pump 24 for supplying water in the water tank 20 to the vaporization chamber 1, an operation unit (pump switch 31) for outputting a drive signal of the electric pump 24, and the electric pump 24 are driven based on an output signal of the operation unit The control unit 30 is provided with a first signal for supplying an amount of water for generating steady state steam to the vaporization chamber 1 and an amount of water for temporarily generating an increased amount of steam larger than the steady state steam to the vaporization chamber 1 The electric pump 24 is driven based on the second signal to output the first signal and the second signal by one operation unit, and the second operation is performed by a manual operation different from the operation of outputting the first signal. A signal is output Those composed urchin.

  According to this configuration, it is possible to realize a steam ejector equipped with a steam increase mechanism, without impairing the usability due to the enlargement of the main body shape and the weight increase. As a result, it is possible to enhance the steam effect such as wrinkle extension by the increased steam. In particular, different signals can be output by one operation unit, and the increase steam can be generated by the manual operation different from the steady steam, so that the steady steam and the increase steam can be reliably and easily operated.

  The operation unit is configured to output the first signal in the on operation, and output the second signal in the plurality of intermittent on operations. Thus, the increase steam can be generated by a manual operation different from the steady steam, and different signals can be reliably and easily output by one operation unit.

  The control unit 30 is configured to be able to drive the electric pump 24 based on the second signal after a predetermined time (t3) has elapsed after driving the electric pump 24 for a short time based on the second signal. . As a result, it is possible to quickly recover the temperature of the vaporization chamber 1 by suppressing the temperature drop when generating the additional steam, and it is possible to enhance the steam effect by using the additional steam at predetermined intervals.

  The control unit 30 is configured to be able to drive the electric pump 24 based on the second signal after driving the electric pump 24 for a predetermined time (t2) based on the first signal. Thereby, since water is filled in the water pipe 29 for transferring water from the water tank 20 to the vaporization chamber 1 by use of the steady steam, it is possible to prevent the problem that the steam is not spouted when using the additional steam.

  Moreover, the control part 30 is comprised so that the heater 2 may be in an energized state, if a 2nd signal is output from an operation part. As a result, when the second signal is output from the operation unit, even if the heater 2 is in the OFF state, it is energized before the temperature decrease is detected, so the temperature decrease when the increase steam is generated Can be suppressed.

  As described above, the steam ejector according to the present invention is useful as a steam ejector because the steam effect by the additional steam can be enhanced without impairing the usability.
