TECHNICAL FIELD The present invention relates to a steamer that blows steam onto a textile product such as clothing and presses the fabric of the textile product to smooth out wrinkles.

Conventionally, many steamers of this type have been reported. and a steam ejection hole for discharging steam has been reported (for example, Patent Document 1).

JP 2017-042554 A

In the steam iron of Patent Document 1, the steam hits the hanging surface member when the steam blows out, and the temperature of the hanging surface member rises. It was troublesome because it was necessary to adjust the temperature of the hanging surface of the hanging surface member. In addition, the base with the vaporization chamber and the hanging surface member are in close contact with each other, and both are made of members with good thermal conductivity. Since the temperature rises, the maximum temperature of the vaporization chamber is limited to 200°C, and the duration of steam, which is the time during which steam can be generated, cannot be maintained longer than this duration from 200°C.

SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a steamer capable of suppressing the temperature rise of the hanging surface.

A second object of the present invention is to provide a steamer capable of keeping the duration of steam longer.

A steamer according to the present invention comprises a steamer body having steam ejection holes for ejecting steam, and a power supply device for supplying a power supply voltage to the steamer body. The steamer body has a metal plate fixed to the bottom surface of the cover, and the steamer body includes a steam generator for vaporizing a liquid, and a steam joint provided between the steam generator and the metal plate and having the steam ejection hole. Further, the metal plate has a steam hole with an inner diameter larger than the diameter of the steam ejection hole, and the heat shield cover has an insertion hole through which the steam joint can be inserted. The steam joint protrudes from the bottom surface of the heat shield cover when the steam joint is inserted into the heat shield cover, and the steam joint elastically contacts the metal plate when the metal plate is fixed to the heat shield cover. and the steamer main body is provided with the metal plate so that the corresponding steam holes are positioned around the steam ejection holes.

According to the invention of claim 1, the steam does not hit the metal plate when the steam is ejected, so that the temperature rise of the metal plate can be suppressed. Therefore, even with textiles having different melting temperatures, wrinkles can be smoothed by pressing the cloth of the textile product after steaming with the metal plate hanging surface without adjusting the temperature of the metal plate hanging surface.

According to the invention of claim 2, wrinkles can be smoothed out cordlessly by pressing with the hanging surface of the metal plate after steaming.

According to the invention of claim 3, it is possible to suppress the heat of the steam generator from being transmitted to the metal plate, thereby suppressing the release of heat from the metal plate to the outside air. Furthermore, even if the temperature of the steam generator is raised, the temperature of the metal plate does not rise, and the temperature of the steam generator can be set higher, and the temperature at the beginning of using steam can be started from a higher temperature. The duration of steam, which is the time during which steam can be generated, can be kept longer, and the durability of steam generation in a cordless steamer can be increased.

A sheathed heater 7 serving as a heating means is bent and embedded in the substrate 8 in a substantially U shape when viewed from above. A vaporization chamber 9 for generating steam is formed near the sheathed heater 7 on the upper surface of the base 8, and a fitting groove 18 for fitting a steam joint 38, which will be described later, is formed on the lower surface of the base 8. be done. The fitting hole portion 18 has a step portion 18a that contacts the upper edge portion of the steam joint 38, and is configured so that the steam joint 38 does not come into contact with the bottom surface 18b of the fitting groove portion 18, so that the steam joint 38 is fitted. A steam chamber 19 surrounded by the fitting groove portion 18 and the upper surface of the steam joint 38 is formed when the fitting groove portion 18 is fitted. The vaporization chamber 9 and the fitting groove 18 communicate with each other through the hole 20 so that the steam generated in the vaporization chamber 9 flows through the hole 20 into the steam chamber 19 . The substrate 8 is also provided with a metal plate-like vaporization chamber lid 44 attached and fixed to the substrate 8 , and the vaporization chamber lid 44 forms the upper surface of the vaporization chamber 9 .

Reference numeral 39 denotes a stainless steel plate-like hanging surface member fixed to the bottom surface of the lower heat shield cover 12, that is, the bottom surface of the steamer main body 1. An opening 41 is formed in this hanging surface member 39 . The steam hole 41 is formed in a truncated cone shape in which the diameter of the lower surface of the hanging surface member 39 is larger than the diameter of the upper surface of the hanging surface member 39 .

In this embodiment, a steam joint 38 as a silicone packing is sandwiched between the base 8 and the hanging surface member 39 . Silicone rubber generally has a low thermal conductivity, and the heat of the substrate 8 is not directly transmitted to the hanging surface member 39 because the vaporization chamber 9 and the hanging surface member 39 pass through the steam joint 38 . In addition, the base body 8 and the lower heat shield cover 12 are not in contact with each other, and in the space surrounded by the upper heat shield cover 11 and the lower heat shield cover 12, especially between the entire upper surface of the lower heat shield cover 12 and the base body 8, A space 54, which is an air layer, is formed between the two to suppress the heat of the vaporization chamber 9, that is, the heat of the substrate 8 from being transferred to the lower heat shield cover 12 and the hanging surface member 39. As described above, the upper heat shield cover 11 and the lower heat shield cover 12 are made of heat-resistant plastic, and plastic generally has low thermal conductivity. It suppresses transmission to the hanging surface member 39 via the under cover 12. - 特許庁With such a configuration, the heat of the vaporization chamber 9 is suppressed from being transferred to the hanging surface member 39, so that the hanging surface member 39 can be kept at a low temperature, and further, the release of heat from the hanging surface member 39 to the outside air is suppressed. By doing so, the steam generation time, which is the time during which steam can be generated, is increased, and the steam generation durability of the cordless steamer main body 1 is enhanced.

Next, the structures of the base body 8 and the lower heat shield cover 12 will be described in more detail with reference to FIGS. 4(A) to 4(C). Here, FIG. 4 shows an exploded perspective view of the steamer main body 1 from below, FIG. 4A is an exploded perspective view with the hanging surface member 39 removed, and FIG. FIG. 4C shows an exploded perspective view with the lower heat cover 12 removed, and FIG. 4C shows an exploded perspective view with the hanging surface member 39, the lower heat shield cover 12 and the steam joint 38 removed.

As shown in FIG. 4(C), the fitting groove portion 18 of the present embodiment is formed to have substantially the same cross-sectional shape as the steam joint 38 up to the stepped portion 18a, and the cross section is one size smaller from the stepped portion 18a to the bottom surface 18b. formed. Therefore, when the steam joint 38 is inserted into the fitting groove portion 18, the upper edge of the steam joint 38 contacts the stepped portion 18a and does not go any further. A steam chamber 19 surrounded by the upper surface is formed.

As shown in FIG. 4B, the steam joint 38 has a contact surface 38a that comes into contact with the hanging surface member 39, and a through hole 38b formed in the contact surface 38a and through which the steam from the steam chamber 19 is ejected. is doing. The through holes 38b of this embodiment are formed in the same number as the steam holes 41, and the steam chamber 19 and the steam holes 41 are configured to communicate with each other through the through holes 38b. The diameter of the through-hole 38b is formed smaller than the inner diameter of the steam hole 41, and when the hanging surface member 39 is installed under the heat shield cover 12, the steam hole 41 is arranged around the through-hole 38b. be done. As described above, the space 54, which is an air layer, is formed between the entire upper surface of the lower heat shield cover 12 and the substrate 8, and is interposed between the two, so that the heat of the vaporization chamber 9, that is, the heat of the substrate 8 is dissipated. This suppresses the transmission of heat to the lower heat shield cover 12 and the hanging surface member 39, and suppresses the release of heat from the hanging surface member 39 to the outside air.

As shown in FIG. 4(A), the lower heat shield cover 12 has a bottom surface 12a and an insertion hole 12b having a cross section substantially the same shape as the steam joint 38, which is formed in the bottom surface 12a. When the steam joint 38 is attached to the base 8, the lower heat shield cover 12 is placed on the upper heat shield cover 11, and the steam joint 38 is inserted into the insertion hole 12b, the contact surface 38a becomes slightly higher than the bottom surface 12a. configured as Therefore, when the hanging surface member 39 is installed under the heat shield cover 12 , the contact surface 38 a first contacts the hanging surface member 39 , and then the bottom surface 12 a contacts against the elastic force of the steam joint 38 . A steam hole 41 is positioned around the through hole 38b, and the steam chamber 19 and the steam hole 41 communicate with each other through the through hole 38b. Therefore, the substrate 8 does not come into contact with the steam hole 41 , that is, the hanging surface member 39 , and the heat of the substrate 8 provided with the vaporization chamber 9 is not directly transmitted to the hanging surface member 39 through the steam pipe 10 . Therefore, even if the temperature of the vaporization chamber 9 is raised, the temperature of the hanging surface member 39 does not rise, and the temperature of the vaporization chamber 9 can be set higher, and the temperature at the beginning of steam use can be started from a higher temperature. Because you can, you can keep the steam duration longer. In addition, since the temperature of the hanging surface member 39 is always low when the steamer main body 1 is in use, wrinkles of various fabrics with different heat resistance temperatures and melting temperatures can be smoothed without adjusting the temperature of the hanging surface of the steamer main body 1. After use, it can be placed directly on a table with the hanging surface member 39 facing downward, eliminating the need for a heat-resistant table.

Next, in the above construction, the operation of the steam function will be described. Subsequently, the steamer main body 1 is placed on the mounting table 2, and a power plug (not shown) of the mounting table 2 is inserted into an outlet, thereby supplying power supply voltage to the steamer main body 1. FIG. When the power switch 33 is pressed in this state of power supply, the temperature control device 35 controls the temperature of the substrate 8 inside the steamer body 1 so that the temperature of the substrate 8 detected by a thermistor (not shown) as temperature detecting means reaches a predetermined temperature. controls the energization of the sheathed heater 7 to heat the substrate 8 including the vaporization chamber 9, causing the energization lamp 34 to blink. On the other hand, when the temperature control device 35 detects that the temperature of the substrate 8 has reached a predetermined temperature, the temperature control device 35 causes the energization lamp 34 to light up. Therefore, the user can understand at a glance whether the steamer main body 1 can be used or not. When the power switch 33 is pressed while the steamer main body 1 is in use, the temperature control device 35 controls the power supply to the sheathed heater 7 so that the temperature of the substrate 8 detected by the thermistor reaches a predetermined temperature. Alternatively, the substrate 8 including the vaporization chamber 9 may be heated to cause the energization lamp 34 to blink.

Next, the action of using the steamer main body 1 will be described. Grasping the grip portion 25, the steamer main body 1 is separated from the mounting table 2, and the hanging surface member 39 is directed toward the cloth to be steam-spouted, and the steam lever is pressed. 30 is pulled up, the valve 43 of the drip port 42 in the water tank 14 is opened, and water drips into the vaporization chamber 9 at a constant speed. At this time, if the temperature of the substrate 8 has reached a predetermined temperature, the water is vaporized in the heated vaporization chamber 9 to generate steam, and as indicated by the arrow in FIG. The steam passes through the steam chamber 19 and passes through the through hole 38b communicating with the steam chamber 19, so that a predetermined amount of steam can be jetted onto the fabric. Therefore, the base body 8 having the vaporization chamber 9 and the sheathed heater 7 functions as a steam generator for vaporizing liquid water.

On the other hand, as described above, in the steamer main body 1, since the heat of the vaporization chamber 9, that is, the base body 8 is suppressed from being transferred to the hanging surface member 39, the hanging surface member 39 can be kept at a low temperature, and the melting temperature can be lowered. Even if a different textile product is used, wrinkles can be smoothed out by pressing the fabric of the textile product without adjusting the temperature of the hanging surface of the hanging surface member 39.例文帳に追加After the steamer body 1 is used, it can be placed directly on a table with the hanging surface member 39 facing downward. Furthermore, even if the temperature of the vaporization chamber 9 is raised, the temperature of the hanging surface member 39 does not rise, and the temperature of the vaporization chamber 9 can be set higher, and the predetermined temperature as the temperature at which steam is first used can be set higher. Since it can be started from , the steam duration can be kept longer.

As described above, the steamer of this embodiment includes the steamer main body 1 having the through holes 38b as steam ejection holes for ejecting steam, and the mounting table 2 as a power supply device for supplying power supply voltage to the steamer main body 1. In addition, the steamer body 1 further has a hanging surface member 39 as a metal plate on the bottom surface. , and the steamer body 1 is provided with a hanging surface member 39 so that the corresponding steam holes are positioned around the steam ejection holes, and the steam hits the hanging surface member 39 when the steam is ejected. Therefore, the temperature rise of the hanging surface member 39 can be suppressed. Therefore, even for textile products having different melting temperatures, wrinkles can be smoothed by pressing the cloth of the textile product with the hanging surface member 39 after steaming without adjusting the temperature of the hanging surface of the hanging surface member 39. - 特許庁

The steamer main body 1 of this embodiment further includes a base body 8 as a steam generating device having a vaporization chamber 9 and a sheathed heater 7 to vaporize liquid water. It is detached and steam is ejected in a state in which power supply to the base body 8 is cut off, and it is cordless and can be pressed by the hanging surface member 39 after steaming to smooth out wrinkles.

Further, the steamer of this embodiment has a structure in which a space 54 for suppressing the release of heat to the outside air is formed between the lower heat insulating cover 12 having the hanging surface member 39 and the base body 8 . Therefore, it is possible to suppress the heat of the base body 8 from being transmitted to the lower heat shield cover 12 and the hanging surface member 39, and to suppress the release of heat from the hanging surface member 39 to the outside air. Furthermore, even if the temperature of the vaporizing chamber 9 of the substrate 8 is raised, the temperature of the hanging surface member 39 does not rise, and the hanging surface member 39 can be kept at a low temperature, so that the temperature of the vaporizing chamber 9 can be set higher. To increase the durability of steam generation in a cordless steamer main body 1 by starting the temperature at the beginning of using steam from a higher temperature to keep the duration of steam, which is the time during which steam can be generated, longer. can be done.

Figures 6-8 show a steamer according to a second embodiment of the invention. In addition, the same code|symbol is attached|subjected to the structure which is common in the steamer of 1st Example, and the same description is abbreviate|omitted as much as possible in order to avoid duplication.

FIG. 6 shows a longitudinal sectional view of the steamer main body ^1II of this embodiment. In this embodiment, a base portion corresponding to the substrate 8 of the first embodiment is composed of a PTC heater 71. As shown in FIG.

Conventionally, in the steam structure of steamers and steam irons, the amount of steam that can be generated was determined in proportion to the temperature of the surface to be applied. Therefore, when the application surface needs to be supplied with water at a low temperature, first, the water in the water tank is sprayed directly on the textile products such as clothing without vaporizing with mist or the like to promote the swelling of the fibers, and then the application surface is cooled. A method has been proposed for smoothing out the wrinkles of the textile product by blowing a small amount of steam onto the textile product.

However, the conventional structure in which water is directly sprayed with a mist or the like and low-temperature steam is jetted out is insufficient in the amount of moisture given to the textile product, and is inconvenient for the user. In addition, the mainstream of the conventional structure is that a sheathed heater as a heating means is embedded in the inside of the base portion. The shape of the base part of the size was increased, and the capacity of the base part was increased. Therefore, in this embodiment, a PTC heater is employed as the heating means so that the thickness of the base portion can be suppressed and the temperature control can be finely set.

The structure of this embodiment will be explained with reference to FIG. 6. 1 ^II is an iron body corresponding to the main body of a steamer ^. prepared for. Reference numeral 72 denotes a thermistor as temperature detecting means, and the temperature control device 35 turns on the PTC heater 71 so that the temperature of the PTC heater 71 detected by the thermistor 72 becomes the set temperature set by the iron temperature control mechanism 75. It's electrically controlled. With this configuration, the thickness of the base portion is only the thickness of the mounted PTC heater 71, so the thickness of the base portion can be reduced, and the base capacitance can be suppressed accordingly. . In addition, since the PTC heater 71 also serves as the base portion, the temperature difference between the PTC heater 71, which is the heat source, and the PTC heater 71 as the base portion, which has approximately the same temperature as the hanging surface, can be eliminated when performing temperature control. Therefore, the temperature differential of the PTC heater 71 with respect to the set temperature can be reduced, and the temperature difference at the time of stability can be reduced. Therefore, it becomes possible to set a plurality of set temperatures.

A boiler type tank 73 is provided above the PTC heater 71 and serves as a tank for storing liquid and a steam generator. Reference numeral 74 denotes a boiler heater, which is a heat source different from the PTC heater 71 and is provided in the lower part of the boiler tank 73, and is ON/OFF controlled by the temperature control device 35 to control the inside of the boiler tank 73. evaporating the liquid. The vaporized steam is jetted through the steam hole 41 as it is after passing through the steam pipe 10'. By configuring in this way, the PTC heater 71 and the boiler heater 74 can be operated independently.

FIG. 7 shows a method of controlling ON/OFF switching of the PTC heater 71 and the boiler heater 74 as an example of this embodiment. As shown in the figure, when one heater is ON, the temperature control device 35 controls the other heater to be OFF, alternately energizing the two heaters. Therefore, the power consumed by the heater in the OFF state can be supplied to the heater in the ON state, and by repeating ON/OFF one by one, the maximum power consumption that can be supplied to one heater is increased and the load due to power consumption is reduced. can be made

FIG. 8 is a graph showing the relationship between the steam amount and the application surface temperature of the conventional steam iron and the iron body ^1II of the present embodiment. Referring to FIG. 1, conventionally, the hanging surface member 39 is in close contact with the base portion provided with the vaporization chamber. Was. Therefore, when the temperature of the hanging surface member 39 of the conventional steam iron is 225°C, the amount of steam is as large as 50 ml because the vaporization chamber is also at a high temperature. When the temperature of the hanging surface member 39 is 150°C, the amount of steam is 20 ml, and the amount of steam decreases in proportion to the temperature of the hanging surface member 39. The temperature in the vaporization chamber reached around 100°C, and the water could not be vaporized, and steam could not be generated.

On the other hand, in the iron body 1 ^II of this embodiment, since the PTC heater 71 as a heat source for raising the temperature of the hanging surface member 39 and the boiler heater 74 as a heat source for generating steam are provided separately, It is constructed so that a large amount of steam can be generated without being affected by the temperature of 39. Therefore, even if the temperature of the hanging surface member 39 varies from 0°C to 225°C, the amount of steam ejected does not change and is 50 ml. can be done. Therefore, even when the hanging surface member 39 is in a low temperature state, a large amount of high-pressure steam can be ejected.

As described above, in the iron main body 1 ^II corresponding to the main body of the steamer of this embodiment, the base portion is composed of the PTC heater 71, and the thickness of the base portion can be thinner than that of the steam iron employing the sheathed heater. . Therefore, the differential of the temperature of the PTC heater 71 with respect to the set temperature can be reduced, and the temperature difference at the time of stability can be reduced. Therefore, it becomes possible to set a plurality of set temperatures.

The iron main body 1 ^II of this embodiment is equipped with a boiler type tank 73 as a steam generating device, and is composed of a boiler heater 74 as a heat source separate from the PTC heater 71 as a base portion. Therefore, by separately providing a PTC heater 71 as a heat source for raising the temperature of the hanging surface member 39 and a boiler heater 74 as a heat source for generating steam, a large amount of high pressure steam can be generated regardless of the temperature of the hanging surface member 39. Allows for ejection.

Further, in the iron body 1 ^II of the present embodiment, when one of the PTC heater 71 and the boiler heater 74 is ON, the other heater can be controlled to be OFF. Therefore, by repeating ON/OFF one by one, the maximum power consumption that can be supplied to one heater can be increased, and the load due to the power consumption can be reduced.

A steamer according to a third embodiment of the present invention will now be described with reference to FIGS. 9-12. It should be noted that the same reference numerals are given to the structures common to the above embodiment, and the same descriptions are omitted as much as possible to avoid duplication.

Conventionally, in a steamer with a power cord, the power cord is wound on a cord reel, and a configuration has been proposed in which the cord reel is operated by pressing a cord reel winding button to wind the power cord. However, winding with this cord reel is possible even when the steamer main body is energized, and if the cord reel winding button is touched by mistake, the power cord will be wound up, and there is a danger that the use of the steamer will be in a dangerous state. was there. Therefore, in this embodiment, the cord reel winding button is locked when the steamer main body is energized, and the winding operation is disabled to improve safety.

FIG. 9 shows a top view of the iron of this embodiment, and FIG. 10 shows a vertical sectional view of the iron of this embodiment. 1 ^III is an iron main body corresponding to the main body of a steamer, and 76 is a cord for winding a power cord that directly supplies a power supply voltage to the iron main body 1 ^III . is the reel. The cord reel 76 is arranged from the rear side of the grip portion 25 to the rear side of the outer cover 17 ′, and the internal power cord is electrically connected to the sheathed heater 7 .
