Description

  The present invention relates to a hair conditioner, and more particularly to a portable hair dryer of the type designed to be used with an attachment for deflecting the air flow generated from the outer cylinder of the portable dryer. Is.

  Portable dryers used for styling hair are well known and are commonly used by personal and professional hairdressers.

  Such a dryer is not limited to the following, for example, a comb for combing hair when drying, an air flow from the outlet portion of the dryer outer cylinder portion is diffused or dissipated, and A diffuser for reducing the speed of the air flow that exits and diffusing the air flow over a wide area, and / or concentrating the air flow ejected from the outlet of the outer cylinder of the dryer and / or It is common to have a hairdressing accessory such as a concentrator to increase the velocity of the air flow.

  When a user or a beautician wants to adopt an attachment, the attachment is usually pressed against the end of the outer cylinder of the dryer to temporarily frictionally engage or the end of the outer cylinder. It is held by being clipped to.

  US Pat. No. 6,775,922 granted to Langley and the like incorporated as a reference in the present invention is an engagement forming portion provided on the outer cylinder portion and a complementary formation portion provided in the apron portion of the attachment. A fixing mechanism is provided.

  Once the attachment is held on the portable dryer, the dryer is ready for operation, and an air stream flows from the dryer through the attachment and is ejected from the ejection section.

  If the airflow hits an obstacle or is blocked at the spout of the attachment, that is, if the spout is placed close to the scalp, the portable dryer is overheated, thereby causing the motor Will break down.

  The overheating of the dryer occurs when a sufficient air flow is not ejected from the attachment and a back pressure is formed inside the dryer.

  The attachment with a diffuser disclosed in U.S. Pat. No. 4,848,007 granted to Montagnino is heated to blow out the heated air when the diffuser is not moving in order to prevent overheating of the dryer. When moving, an exhaust slot is provided so that cooling air is introduced.

  However, even if the slot is used to prevent overheating of the dryer, the airflow entering and exiting the slot is not used for the purpose of drying the hair. .

  The inflow and outflow of the air stream is concentrated in a small part of the diffuser.

  In other words, the inflow and outflow of the air flow in the slot are not uniform along the side wall, for example, even when the hair is dried, it is not used in the radial direction. It is simply used to introduce cooled air into the heated diffuser or to discharge heated air when the diffuser is not movable.

  In the known air-permeable outer cylinder disclosed in US Pat. No. 6,775,922 to Langley et al., The attachment has a plurality of openings and a closed ejection end. .

  The opening of the breathable outer cylinder allows the air flow to be discharged from the attachment while the dryer is in operation to prevent the dryer from being overheated. On the other hand, the radial air flow ejected from the opening is very strong when the attachment is used with a professional model dryer, for example when it is used to dry hair. Too much.

  Although the said structure provides the said airflow over the length direction of the said attachment, since there is much air quantity ejected from the said opening part, it will disturb a hairstyle severely. .

  Therefore, when the air flow is disturbed at the ejection part, it is possible to prevent overheating of the dryer and to dry the hair at a position along the length of the attachment. There is a demand for attachments used in portable hair dryers.

  Therefore, this invention provides the attachment for hair dryers used with the portable hair dryer which has the outer cylinder part which has an exit part.

  Referring to FIGS. 1-4, the attachment 30 is a substantially hollow body portion provided with a porous side wall portion 52 having a substantially uniform diameter having a row 54 of openings. 50 is shown as a breathable outer cylinder attachment.

  Although the first end portion 38 of the attachment 30 is also shown as the apron portion, it receives the outer cylinder portion 20 and the ejection portion 58 ejects the air flow in the axial direction. It is configured.

  In addition, the attachment 30 is preferably arranged in a plurality of axially spaced apart and projecting radially directions that are integrally formed with or with the side wall 52. An annular collar 60 is provided.

  Preferably, the generally circular opening 54 is preferably provided in the side wall 5 between the annular collars 60.

  Referring to FIG. 2, when the portable dryer 10, for example, does not receive any significant obstacles in the air flow at the ejection portion 58, the air flow is And is converged when it flows into the attachment 30.

  As the air flow enters the convergence area, its velocity increases and the pressure within the convergence area decreases.

  This phenomenon is known as the Venturi effect.

  The local low pressure region in the converging region (ie, the attachment 30) operates to move the ambient air from the high pressure portion toward the low pressure portion, ie, the air flow is The air flows from the outside of the part 52 through the opening 54 and flows into the attachment 30, and the inflow air flow is combined with the air flow from the dryer there and is ejected from the ejection part 58.

  Since an additional air flow is introduced into the system through the side wall 52, the opening 54 is generally on the order of 5 to 10% in volumetric flow than the dryer alone. Many additional airflows ejected from the ejection part 58 are supplied.

  In use, the attachment 30 forms an air flow under the hair and, as an effect, sucks moisture from the hair and introduces it into the attachment.

  The heel portion 60 is configured to separate and separate hair, and the bundle of hair is sucked between the opening portion 54 of the side wall portion 52 and between the ridge portions.

  Furthermore, in addition to the combing operation of the hook-shaped part 60 for dividing the hair, the attachment 30 is intended to be used together with the comb part or the brush part.

  Usually, the entire length of the side wall 52 is used so that the hair is preferably dried from its root to its tip without excessive heating or drying of the scalp. Is hereinafter referred to as radial drying.

  In such radial drying, a moderately compatible method is provided for relatively severely turbulent flow associated with a dryer having a standard outer cylinder set at high heat / fan speed. .

  Furthermore, the radial drying provides another compatible method for drying the hair along with the concentrated air flow at the spout 58, which is hereinafter referred to as axial drying. (refer to FIG. 4).

  The attachment 30 according to the present invention has a configuration for both the axial drying and the radial drying.

  In the attachment according to the present invention, the openings 54 are arranged along the longitudinal direction of the side wall 52, which are preferably circular, and preferably each on the attachment 30. It has different dimensions according to the position.

  Preferably, there are eight annular rows of the openings 54 arranged in a direction orthogonal to the axis of the hollow body portion 50.

  In a preferred embodiment, the openings in the first three rows arranged towards the spout 58 are the smallest openings, and the diameter of the openings 54S is about 3/16 inch (about 0). .48 centimeters), and the openings in the last three rows arranged toward the apron 38 are the largest openings, and the diameter of the openings 54L is about 5/16 inch ( In addition, the openings in the middle two rows have intermediate dimensions, and the diameter of the openings 54M is about 1/4 inch (about 0.63 centimeters). Meter).

  Also preferably, there are eight axial rows for the openings 54.

  However, it will be appreciated that other dimensions, other arrangements, and other shapes are possible.

  Here, referring to FIG. 4, the portable dryer 10 is arranged so that the air flow is obstructed, for example, the ejection part 58 is arranged very close to the scalp. If so, a back pressure is formed in the attachment 30.

  In a conventional portable dryer 10 using an attachment, the increased pressure leads to a situation where the dryer is overheated due to the lack of sufficient airflow.

  In the attachment 30 of the present invention, the opening 54 is configured to eject an air flow when the dryer is operating, and is further uniformly along the length direction of the side wall 52. It is configured to eject an air stream, whereby an air stream that is effectively released with respect to radial drying can be used.

  Also, the attachment 30 is located at a position where the air flow is subject to considerable obstacles at the ejection end 58 such that the ejection end 58 is located close to the scalp, for example. In the case where it is disposed, back pressure is formed in the attachment 30.

  Instead of the air flow spouting from one local area in the side wall 52, the attachment 30 is generally uniform in the air flow for the entire length of the side wall 52 for radial drying. It is comprised so that it may be ejected over.

  In order to ensure that the air flow is uniformly exhausted from within the attachment 30 into the atmosphere along the length of the side wall portion 52, smaller openings 54S are provided in the attachment. The side wall 52 where the back pressure is accumulated is located, and the larger opening 54L is located in the side wall where the smaller amount of back pressure is accumulated within the attachment. .

  On the other hand, the opening 54M having an intermediate dimension is located in the portion of the side wall 52 where an intermediate amount of back pressure is accumulated in the attachment.

  Therefore, the portable dryer-like attachment of the present invention provides a drying capability regardless of whether or not there is an obstacle in the ejection portion of the attachment.

  The direction of the air flow in the opening 54 is whether or not there is a low pressure difference or a high pressure difference in the attachment 30 compared to the atmosphere (that is, the air flow is at the end of the ejection portion 58). Switching between air flow inflow and air flow outflow on the basis of whether or not there is a significant hindrance.

  When there is no obstacle, the air flow is sucked through the opening 54, and when there is the obstacle, the air flow is ejected from the opening.

  Furthermore, radial drying of the hair occurs at the side wall portion regardless of whether the air flow inflow or airflow outflow exists at the opening 54.

Specific examples of attachments for hair dryers in the present invention have already been described above, but in a more expanded manner and within the scope of the appended claims, the present invention Changes and modifications made to the present invention without departing from the scope thereof will be considered by those skilled in the art.
