3 is a plan view of a lid according to an embodiment in a closed state;

Referring to FIG. 2 , the housing 100 of the dryer 10 according to an exemplary embodiment may include a receiving part 101 . The accommodating part 101 may be formed at the lower front end of the housing 100 , and may accommodate the condenser cover 300 . It may be formed in a shape corresponding to the shape of the condenser cover 300 of the accommodating part 101 . At least two latches provided to be positioned in front of the condenser cover 300 are provided on the inside of the accommodating part 101, so that even if the lead 400 is open, unless the latches are released, the condenser cover 300 is not connected to the accommodating part. It may not deviate from (101).

Also, the lid 400 may include the first part 401 and the second part 402 as described above.

2 and 3 , the first part 401 may include a fixing part 4011 , a fastening part 4012 , and a concave part 4013 .

The fixing part 4011 may be fixedly mounted on the upper end of the receiving part 101 .

The fastening part 4012 is formed on one surface of the fixing part 4011 and may be formed in a shape to accommodate the protrusion 4023 of the second part 402 . For example, the fastening part 4012 may be formed of at least two holes, and each of the fastening parts 4012 may be spaced apart from each other. The protrusions 4023 of the second part 402 may be inserted into each of the fastening parts 4012 to be coupled thereto. In addition, the coupling may be released by the protrusion 4023 . In addition, a fastening member (not shown) that can be engaged with the protrusion 4023 may be provided in the two fastening parts 4012 , respectively. The fastening member may operate to engage or disengage with the protrusion 4023 by pressure.

The concave portion 4013 is a part of the fixing portion 4011 , and may be formed between the two fastening portions 4012 . The concave portion 4013 may be a curved surface that is depressed inwardly so that one surface of the fixing portion 4011 is formed in a concave shape. As shown in FIG. 3 , between the first part 401 and the second part 402 in a closed state by providing such a recess 4013, the existing separation of the first part 401 and the second part 402 It is possible to form a concave space more spaced apart than the distance.

The second part 402 may include an opening/closing part 4021 , a rotating part 4022 , and a protruding part 4023 .

The opening/closing unit 4021 may open or close the condenser cover 300 . The opening/closing part 4021 may be made of an elastic material.

The rotating part 4022 is formed under the opening and closing part 4021 and may be formed in the shape of at least two rings protruding from the inner surface. The rotating unit 4022 is rotatably coupled to the receiving unit 101 so that the opening/closing unit 4021 can rotate around the rotating unit 4022 . The protrusion 4023 is formed on the upper portion of the opening/closing unit 4021 and may protrude from the inner surface of the opening/closing unit 4021 . For example, the protrusion 4023 may include at least two protrusions 4023 , and each of the protrusions 4023 may be spaced apart from each other to correspond to the fastening part 4012 of the first part 401 . The protrusion 4023 may be engaged with the fastening portion 4012 to be coupled. For example, the protrusion 4023 may be fastened to a fastening member provided in the fastening part 4012 . In addition, the protrusion 4023 may advance and press toward the fastening member together with the elastic deformation of the opening/closing part 4021 to transmit the pressure applied to the outer surface of the opening/closing part 4021 to the fastening member. Accordingly, the fastening with the fastening member may be released.

As described above, in the lid 400 according to an embodiment, the opening/closing unit 4021 may rotate around the rotating unit 4022 so that the protrusion 4023 may be accommodated in the fastening unit 4012 . When additional pressure is applied in this contact state, the protrusion 4023 may be fastened to the fastening part 4012 . Accordingly, the first part 401 and the second part 402 may be fixed in a coupled state. That is, the lead 400 may be fixed in a closed state of the condenser cover 300 . In this case, the first part 401 and the second part 402 may be fixed by being spaced apart by a predetermined distance as shown in FIG. 3 .

In addition, the lid 400 in the closed state transfers the pressure applied to one point of the opening and closing part 4021 of the second part 402 to the fastening part 4012 positioned at two points of the first part 401 to open it. state can be disassociated.

For example, the user may open the opening/closing unit 4021 to check the condenser cover 300 accommodated in the housing 100 . In this case, the user may apply pressure to the central portion of the upper portion of the opening/closing unit 4021 .

First, the opening/closing part 4021 may be rotated until it comes into contact with one surface of the fixing part 4011 excluding the concave part 4013 because of the pre-formed separation distance between the first part 401 and the second part 402. . At the same time, the protrusion 4023 formed on the inner surface of the opening/closing unit 4021 may advance to the inside of the fastening unit 4012 .

In such a state, when a greater pressure is applied to the opening/closing unit 4021, a part of the opening/closing unit 4021 opposite to the concave unit 4013 is elastically deformed to the inside of one surface of the fixing unit 4011, that is, the concave part ( 4013 ) and the protrusion 4023 may be further advanced.

Each of the protrusions 4023 may advance to a disengagement point of the fastening part 4012 to press the fastening member, and the coupling between the fastening part 4012 and the protrusion 4023 may be released.

As a result, the lead 400 according to an embodiment transmits the pressure applied to one point of the opening/closing part 4021 to the two fastening parts 4012, respectively, and the fastening part 4012 is connected to the protruding part 4023 by this pressure. The bond can be disconnected. Accordingly, the condenser cover 300 may be exposed to the outside.

In the lid 400 described above, in order for the user to easily open the opening/closing part 4021, the fastening part 4012 and the protruding part 4023 must be disconnected before the opening/closing part 4021 comes into contact with the concave part 4013. .

Hereinafter, with reference to FIGS. 4 and 7 with respect to the correlation between the opening load and the thickness t of the opening and closing part 4021 for facilitating release of the coupling between the fastening part 4012 and the protrusion part 4023, and the moving distance and the opening load. to explain

6 shows the experimental results of measuring the opening load required for the lid according to the thickness (t) of the opening and closing portion 4021.

7 is a graph showing the experimental results of FIG. 6 .

Referring to FIG. 4 , the coupling between the protrusion 4023 and the fastening part 4012 may or may not be released depending on the moving distance of the opening and closing part 4021 that is deformed in the direction of the arrow.

The section A is a section including a distance between the outer surface of the opening and closing part 4021 and the outer surface of the fixing part 4011 . When the moving distance of the opening/closing part 4021 is within the section A, the protrusion 4023 may not reach a point at which the disengagement of the coupling part 4012 may be operated. That is, in order for the disengagement to operate, a greater load is applied to the opening/closing part 4021 and the pressure applied by each of the protrusions 4023 to the fastening part 4012 should increase.

The section B is a section including the distance between the outer surface of the fixing portion 4011 and the maximum inner point of the concave portion 4013 . The opening/closing unit 4021 may enter within the range of section B when a greater load is applied than in the case of section A described above. When the moving distance of the opening/closing part 4021 is within the section B, the protrusion 4023 reaches a point at which the disengagement of the coupling part 4012 is operated, and the coupling of the protrusion 4023 and the coupling part 4012 may be released. there is. This normal operation section B may vary depending on the depth of the recessed part 4013, and in order to design an optimal recessed part 4013, an appropriate thickness t of the opening/closing part 4021 or a suitable material constituting the opening/closing part 4021 needs to be selected.

The section C is a section out of the maximum inner point of the concave portion 4013 , and elasticity of the opening and closing portion 4021 may be lost. That is, when the moving distance of the opening/closing unit 4021 is within the section C, the opening/closing unit 4021 may be permanently deformed. Therefore, section C cannot be applied to ensure product reliability.

After all, the interval for the lead to operate normally can be expressed as follows.

Amm < A+(B x k)

In this case, k may be a deformation amount correction constant of the material constituting the opening/closing part 4021 .

For example, the material of the opening/closing part 4021 may be ABS resin, and k is the deformation amount correction constant of the ABS resin when a load required when the protrusion part 4023 and the fastening part 4012 is normally operated so that the coupling is disengaged. can be

Referring to FIG. 5A , when the opening/closing unit 4021 is made of ABS resin, the deformation of the opening/closing unit 4021 generally has the following relationship.

Travel distance ∝ 1/thickness

That is, the moving distance and the thickness t of the opening and closing part 4021 are inversely proportional as shown in FIG. 5A .

In addition, referring to FIG. 5B , when the opening/closing unit 4021 is made of ABS resin, the deformation of the opening/closing unit 4021 generally has the following relationship.

Travel distance ∝ Operating force

That is, the moving distance and the operating force of the opening/closing unit 4021 are proportional to each other as shown in FIG. 5B .

In this case, the operating force may be an opening load to be applied to the opening and closing part 4021 when the protrusion 4023 and the fastening part 4012 are normally operated so that the coupling is released.

Therefore, the minimum thickness of the opening and closing part 4021 is the minimum distance that the protrusion 4023 can release from the fastening part 4012 before the opening and closing part 4021, which is elastically deformed by an external force, contacts the concave part 4013. It can be set to a thickness that can be used.

Referring to FIG. 6 , samples having different thickness t of the opening/closing part 4021 were prepared, and an experiment was performed to measure the required opening load in each case.

The thickness (t) of the opening/closing part 4021 used in Experiments 1 to 7 was different from 2.25 mm to 3.75 mm, and the following experimental methods were equally applied to each.

1) Prepare push-pull gauge measuring equipment.

2) Press the center of the opening/closing unit 4021 with a push-pull gauge measuring device until the opening/closing unit 4021 is opened.

3) Record the maximum measured value (at this time, measure 3 times and record the average value of each maximum measured value).

Referring to FIG. 7 , it can be seen from the results of Experiments 1 to 7 that the maximum measured value increases as the thickness t of the opening and closing part 4021 increases. That is, as the thickness t of the opening and closing part 4021 increases, the opening load required to separate the protrusion 4023 from the fastening part 4012 increases.

However, in Experiments 1 to 3, the opening/closing portion 4021 came into contact with the concave portion 4013 before the protrusion 4023 was separated from the fastening portion 4012 .

In the cases of Experiments 4 to 7 , the protrusion 4023 was separated from the fastening portion 4012 before the opening/closing portion 4021 came into contact with the concave portion 4013 . Through this, it can be seen that the minimum thickness of the opening and closing part 4021 effective for the lead 400 to operate normally is 3 mm.

However, from Experiment 6 in which the thickness t of the opening and closing part 4021 is 3.5 mm, a large force is required to open the opening and closing part 4021 .

Accordingly, the thickness t of the opening/closing part 4021 may be set to 3 mm to 3.5 mm.

In addition, referring back to FIG. 7 , it can be seen that the slope of the section having the thickness t of 3 mm to 3.25 mm among the sections of Experiments 4 to 7 in which the thickness t of the opening and closing part 4021 is 3 mm to 3.75 mm is the smallest. can Therefore, it can be seen that in order for the user to open the lid 400 by applying an appropriate opening load, that is, pressure, the thickness t of the opening and closing portion 4021 is preferably set to 3.2 mm.
