Description

  The present invention relates to a gas dryer suitable for carrying.

General hair dryers are assumed to be used in homes where a commercial AC power supply (AC100-120VAC 200-240V) is supplied, or in hotels, hair salons, and beauty salons. Cannot be used at all. (Patent Document 1)
For this reason, portable dryers have been proposed. The biggest problem with portable dryers is that hot air with a low air temperature and a large air volume cannot be taken out. There is a correlation between the reason why the air temperature cannot be increased and the reason why the air volume cannot be increased.

  For example, even if the calorific value (gas burner combustion amount) is increased and the air temperature is increased, if the air flow is small, it is not suitable for drying hair, and conversely the battery voltage (increasing the number of batteries) is increased to increase the motor speed. Even if the air volume is increased and the air temperature is increased, it is not suitable for drying as the air temperature is low.

  That is, in the case of carrying, the weight cannot be increased and the size of the dryer body cannot be increased. As a result, the number of batteries cannot be increased spilloverly, the number of rotations of the fan cannot be increased, and the air volume is reduced.

  If a battery having a high battery voltage is used to increase the rotational speed of the fan, the battery capacity is reduced and the usage time is shortened. Furthermore, when the usage time is increased, the battery capacity may be increased, but the weight and size of the battery increase, which is not suitable for carrying.

  Similarly, it is possible to increase the heat generation amount (combustion amount) and increase the air temperature by increasing the gas consumption in the burner. However, since the combustion time is shortened, it is necessary to increase the internal capacity of the gas cylinder. is there. Increasing the internal capacity of the gas cylinder in this way increases the size of the gas cylinder and is not suitable for carrying.

For the above-described reasons, there is a so-called pistol type hair dryer in which a gas cylinder is stored using a hollow portion in a handle. (Patent Document 2)
JP-A-5-137612 JP-A-6-133816

  However, in the case of the above-described prior art, it is not necessary to separately provide a gas cylinder storage portion by storing the gas cylinder in the handle, but since the battery is also stored in the same handle, the thickness of the handle is small. There is a drawback that it becomes large and difficult to grasp. If the handle is made thinner, it will be easier to grip, but the gas cylinder will be smaller in size, the combustion amount (gas consumption) will be lower, the air temperature will be lower, the combustion time will be shorter, and at the same time the battery size will be smaller and the continuous use time will be shorter.

  In particular, detachably storing the gas cylinder in the handle means that the gas hose connecting the gas cylinder and the burner, the open / close valve provided in a part of the gas hose, the motor power switch, and the positional relationship with each functional part of the ignition device Must be fully considered.

  In detail, the overall vibration, impact, and mechanical movement of the gas cylinder that occur when the gas cylinder is attached / detached touches the opening / closing valve, causing the valve to open unexpectedly, or the gas hose to be crushed and damaged. This may cause a failure of the power switch or the ignition device.

  The present invention makes it possible to increase the size of the gas cylinder by storing the gas cylinder stored in the handle and the functional parts such as the device for opening / closing and igniting the gas and the power switch in a completely separated space. This prevents malfunction of functional parts.

  The present invention relates to a cylindrical casing having an air discharge part on the front side and an intake part on the rear side, a burner, an igniter, a fan and a motor arranged in the cylindrical casing, and connected to the cylindrical casing. A hollow cylinder length handle, a gas flow path opening / closing means to the burner disposed in the handle, an electric path opening / closing means for applying a high voltage to the igniter and disconnecting the motor, and the motor A battery for supplying a driving power to the battery, and the battery is housed in a space accommodating portion formed in a lower portion of the cylindrical casing.

  Further, the cylindrical casing has a circular or elliptical cross-sectional shape in the vertical direction, and the space storage portion is formed in an arc shape along the outer wall surface shape of the cylindrical casing.

  The space storage portion is provided with a detachable boat bottom cover.

  Further, a bulging portion is formed in the lower portion of the cylindrical casing, the upper portion of the handle is pivotally supported by the bulging portion, and the handle is configured to be rotatable. The outer dimensions are set so as to fit within a gap formed between the lower outer wall surface of the cylindrical casing formed by the bulging portion when bent.

  Furthermore, a slide knob for operating the gas flow path opening / closing means and / or the electric circuit opening / closing means is provided on the front wall of the handle. The slide knob has an operation projection and a recess in the cover. When the handle is bent, the slide knob is closed by the gas passage opening / closing means and / or the gas passage is closed by the electric path opening / closing means and / or the power supply to the motor or igniter is shut off. The operation protrusion is positioned in the recess.

  The handle is partitioned into two spaces by a partition plate, a gas flow path opening / closing means to the burner is disposed in one space, and a gas cylinder is detachably mounted in the other space. The movable range of the slide knob is the side wall of the handle excluding the space for installing the gas cylinder.

  According to the present invention, since the battery that supplies the driving power to the motor is housed in the space storage portion at the bottom of the cylindrical casing, this space storage portion is used when the main body is carried or used. It becomes a position where it is hard to hit an instrument or an object, so that there is no poor contact of the battery, and the space storage part is protected from an impact from the outside.

  Since the longitudinal cross-sectional shape of the cylindrical casing is circular or elliptical, the space storage portion of the battery is formed in an arc shape along the outer wall surface shape of the cylindrical casing. The part can be integrated with the external shape of the cylindrical casing, and the image of the strange overhanging part can be removed.

  In addition, since the space storage part is detachably provided with a detachable boat bottom-shaped cover, the inside of the cover in the shape of the boat bottom is the battery storage part, and the boat bottom shape is the appearance of the cylindrical casing Match the shape.

  Further, a handle is pivotally supported on a bulging portion provided at a lower portion of the cylindrical casing, and the space storage portion is positioned in a gap between the handle formed by the bulging portion and the cylindrical casing when the handle is bent. Therefore, even when the handle is folded, the handle does not hit the space storage portion, and the bulging portion of the cylindrical casing necessary for making the handle foldable is used to make the space storage portion An arrangement area (space) can be secured.

  Further, an operating projection is provided on a slide knob for operating the gas flow path opening / closing means and / or the electric circuit opening / closing means provided on the front wall of the handle, and when the handle is bent, the gas flow opening / closing means and the electric circuit opening / closing means can When the road is closed and / or when the power is cut off, the operation projection is positioned in a recess provided in the cover of the space storage unit, so that the slide knob may be accidentally moved when the handle is folded when being carried. Thus, the gas flow path is not opened, the motor rotates, and the igniter does not perform an ignition operation.

  Since the movable range of the slide knob is the side wall of the handle on the upper space side excluding the lower space in which the gas cylinder is stored, no external force is applied to the gas cylinder when the slide knob is operated. Of course, it is important to take out the gas cylinder from the lower space of the handle when carrying it, but it is also necessary to assume that the user has neglected to take out the gas cylinder. .
