Description

[Detailed description of the invention] This invention relates to a dryer with a built-in hot air generator, and its purpose is to effectively store accessory parts.

This invention will be explained below based on illustrated embodiments.

In the figure, reference numeral 1 denotes a dryer main body, which is integrated by joining a rear case 2 and a front case 3, which are vertically divided into two parts.

The front face of the front case 3 is open, and this open face can be opened and closed by attaching and detaching the front cover 4.

Such attachment/detachment is achieved by engaging a pair of left and right engagement holes 5 recessed in the lower part of the front case 3 with a pair of left and right engagement pieces 6 protruding from the lower part of the front cover 4, and opening the upper part of the front case 3. This is done by engaging a claw 8A of an elastic engagement piece 8 protruding from the center of the upper surface of the front lid 4 with a claw 7 formed at the center of the edge.

9 is integrally formed on the upper part of both cases 2 and 3,
The handle 10 that is completed when the parts are combined is a control knob provided on the upper inclined surface of the front case.

The front case 3 is provided with a plurality of storage sections recessed deep from the open surface thereof, one of which is a hose storage section 11 with a semicircular cross section having a predetermined length in the horizontal direction. , 2 is the air mat storage part 1 in the rectangular parallelepiped space located at the bottom of this hose storage part.
2, and 3 is a vertical cord storage part 1 whose upper space extends to the right end surface of the hose storage part 11.
It is 3.

The wall surface forming the lower right half of the hose storage section 11, the right side of the air mat storage section 12, and the left side of the lower half of the cord storage section 13 is a motor storage section recessed from the back side of the front case 3. 14, and these are recessed from the front and rear of the front case 3 by integral molding.

The hose storage portion 11 has a semicircular cross section, but the center of curvature is offset by a dimension (l) in the middle.

That is, the center of this deviation forms a step 15 at the deviation part.

The hose 16 stored in the hose storage section 11 is
It has a cylindrical connecting portion 17 at both ends, and the connecting portions are connected by a telescopic bellows portion 18, which is stored in the hose storage portion 11 in a contracted state.

At the time of such storage, the hose 16 is connected to the step 15.
The ridges of the bellows part 18 of the hose bite into the hose, which helps to keep the entire hose in place, and since the step 15 is formed on the opposite side, it matches the winding direction of the bellows part 18 of the hose, giving an extremely convenient consideration. It is being done.

The right end of the hose storage section 11 and the cord storage section 13
A half-ring-shaped barrier wall 19 is provided protrudingly between the hose 16 and the hose 16, and the end face of the one end connecting portion 17 of the hose 16 is abutted against the barrier wall to prevent the hose 16 from protruding toward the cord storage portion 13 side.

The protruding width of this barrier wall is set to such a size that it blocks the end face of the connection portion 17 of the hose, but does not substantially block the cylindrical space.

Therefore, when the appropriately bundled cord 20 is stored in the cord storage part 13, a part of the cord 20 that tends to spread due to elasticity is allowed in the cylindrical space of the hose connection part 17, and therefore the cord This improves the ability to hold down the cord, prevents strain on the cord, and conversely allows the cord storage section 13 to be made as small as possible.

The cords 20 are led out from the lower part of the cord storage part 13, so that the bundled cords are placed in a position where the upper and lower portions of the cords receive a holding force, and are well placed.

The hose storage section is also provided with a protruding rib 21 for firmly holding the connection section 17 of the hose.

These ribs protrude from the upper and lower walls of the hose storage portion in two pairs on the left and right, corresponding to the hose connecting portions 17, and one or both of the connecting portions 17 are connected to the ribs 2.
1, one of the connecting portions 17 is made to avoid the claw portion 7 of the front case 3, and both of the connecting portions 17 are released from being held by the ribs 21. When in use, a portion of the connecting portion 17 is set to face the position of the claw portion 7 of the front case 3.

As a result, when the hose 16 is not stored properly, the engagement piece 8 of the front cover 4
There is a collision between the lower edge and the outer surface of the hose connecting portion 17, and the hook portion 8A of the front cover 4 and the hook portion 7 of the front case 3 are not engaged, so that the hose 16 is not placed in the normal position. Since the front cover 4 is attached to the front case 3 only after it is re-stored, correct storage is always performed and strain on various parts is eliminated.

In order to reliably provide such an effect, in the illustrated embodiment, the engaging piece 8 is horizontally extended from the upper edge of the front cover 4, and is folded back from a predetermined extending position so that the end thereof is folded back. The engagement piece 8 has a free end, and a claw portion 8A is formed on the midway upper surface of the folded portion.
When is compressed, the claw portion 8A escapes to the free end side,
In addition, the free end is blocked on the extending base of the engagement piece 8, creating tension and resisting the engagement operation.

When the hose 16 is correctly stored and held between the ribs 21, the center of curvature of the hose storage portion 11 is offset, so that the bellows portion 18 bends slightly in the longitudinal direction, and the elastic restoring force of the bellows portion is acts to assist in holding the hose 16 in a more reliable direction.

22 is a hot air generator, which includes a motor M and a blower 2.
3. Heater 24 and a series of air passages 25 between them
It consists of a wind barrel 26 for forming a wind turbine.

The wind body 26 is a blower case 27 made of synthetic resin.
and a metal heater case 28, and the heater case has a relatively long rectangular tube shape.

The heater case 28 is installed correspondingly to the back surface of the hose storage section 11, and the blower case 27 is installed correspondingly from the remaining part of the hose storage section to the motor storage section 14.

The heater case 28 is composed of a member 29 having a U-shaped cross section and a flat plate member 30 that closes the open surface of the U-shape. Therefore, a sufficient gap 31 is formed between the flat plate member 30 and the back surface of the hose storage section because the storage section is semicircular.

This gap acts so that the heat transfer from the heater case 27 to the hose storage part 11 becomes worse, and the hose storage part 1 is made of integrally molded synthetic resin.
1 and the like from the adverse effects of heat, and conversely allows the two to be placed close to each other, allowing for a compact design.

Furthermore, by conveniently arranging the heater case 28, which has a similar length, to the hose storage section 11, which has a relatively long length, it contributes to the realization of the above-mentioned compact design. The heat effect on the hose storage section 11
This can be sufficiently eliminated by the large gap formed by the semicircular cross section that matches the semicircular shape of the hose 16.

On the other hand, the air mat storage section 12 is recessed to approximately match the overlapped depth distance of the hose storage section 11 and the wind barrel 26, and is formed outside the circular bulge of the blower case 27 and the lower surface of the wind barrel 26. It is integrally formed to fit into the space in which it is placed.

The depth of the air mat storage section is long enough to cover the hose storage section 11 and the wind barrel 26, and the width thereof is slightly limited by the circular bulge of the blower case 27.

However, since the air mat is made of a flexible and thin cloth-like material, it can be folded freely and is generally folded regularly into a substantially rectangular shape, so the width of the air mat storage section 12 is not required to be large. The dimensions limited by the bulging part of the blower case are sufficient, and the consideration of the function of each part and the required storage space, as well as the ingenuity of the positional relationship, have greatly contributed to the compact overall structure. It is contributing.

The air mat 32 is inserted between the comforter 33 and the mattress 34, and is connected to the air path 25 of the hot air generator 22.
connected to the other end of the hose 16 connected to the terminal end,
It has the function of introducing hot air, inflating it into a predetermined shape, and blowing it uniformly from the entire surface toward the futon.

For this purpose, the air mat 32 is made of a woven fabric such as nylon taffeta, and has a mesh suitable for pressure loss.

The connection to the terminal end of the air mat air passage 22 is provided by a hose connection portion 17.

Therefore, a cylindrical outlet 35 is provided on the end face of the heater case 28, and the hose connecting portion 17 is fitted into this outlet, and an inlet 36 is formed in a part of the air mat 32. The other connecting portion 17 is connected to this inlet 36, and warm air is thereby introduced into the air mat 32.

This warm air is generated by heat exchange by the heater 24, and the air flow is such that outside air that has flowed into the main body from outside the main body 1 enters the blower 23 from the motor M or the blower case 27 side, The air passes through the air passage 25 and reaches the air outlet 35 .

There is an air intake hole 3 in the front cover 4 to introduce outside air.
6 is provided, and its position is in the motor storage part 1.
4, and in the back wall 37 of this motor housing section, there is an air introduction hole 38 for guiding the outside air taken in from the air intake hole 36 to the blower 23.
is provided.

Further, another air intake hole 39 is provided in the rear case 2 in correspondence with the air mat storage section 12.
It acts as an aid when the air intake hole 36 is unintentionally closed.

A rectangular opening 40 is formed in the side wall of the heater case 28 facing the rear case 2, and the position of this opening is directly above the air intake hole 39 of the rear case 2.

The opening 40 is covered with a box-shaped cover 41 made of synthetic resin.
For this reason, a notch 42 and a cut-and-raised portion 43 are formed on the opposing edges of the opening 40,
A mounting hole 46 is formed in the cover 41 in correspondence with a protrusion 44 that engages with the lower surface of the notch 42 and a screw hole 45 formed in the horizontal part of the cut-and-raised part 43. A screw 47 is screwed into the screw hole 45 for a closed connection. The cover 41 has a predetermined depth, so when the opening 40 is closed, a chamber 48 is formed on the side of the air passage 25 that communicates with the air passage, and a reset type thermal control is performed on this room side. A device 49 and an overtemperature rise preventer 50 are attached.

The overtemperature rise preventer 50 is supported by inserting lead wires at both ends thereof into a pair of hollow bosses 51 that are raised from the cover 41 .

The end of this lead wire is connected to another connecting wire 52 in a cylindrical stator 53, and this stator is inserted and held in the hollow of the boss 51. That is,
Connection is made by crushing the stator 53,
Further, the boss 51 is formed with an insertion hole 54 for the connecting wire 52 and a holding hole 55 with a larger diameter than this, and the stator 53 is inserted and held in this holding hole.
It is blocked by the step created at the border with 4 and placed in place. A reset button 56 of the heat-sensitive controller 49 protrudes from the outer surface of the cover 41, and a recess 57 is formed in the rear case 2 to correspond to the button 56 so that the button can be reset from outside the main body. At the same time, a through hole 58 is formed at the bottom of the recess to allow the button 56 to protrude, and the top of the button is set at a height within the recess so that it will not be operated unnecessarily.

This reset button position is near the air intake hole 39, and is always cooled under the influence of air flow, preventing overheating, and the cover 41
The outer surface of the device is similarly cooled, and a synthetic resin cover protects it from the heat.

The cover 41 is also attached to the side wall of the heater case 27 and has a heat sensitive controller 49 and a temperature overrise preventer 5.
0 is set at a position that is affected by temperature in the lateral direction with respect to the heater 24, and is designed to provide the most suitable operation. In other words, when placed on the top surface of the heater 24, the heat is focused upwards and the operation is performed quickly, while when placed on the bottom surface, the effect of heat is small and the operation is delayed, which is dangerous. If these are arranged, the operating point will be stable and reliable at these average positions.

At this time, since the inside of the cover 41 constitutes a room 48, heat is sufficiently accumulated and not diffused, so that the operation is performed by sensing an appropriate atmosphere.

And, this arrangement inevitably requires the reset button 5.
6 protrudes from the side of the main body, which has the advantage that the operability is further improved compared to the conventional one that protrudes from the bottom of the main body.

Since the heat sensitive controller 49 and the overtemperature rise preventer 50 are fixed in place on the cover 41 in advance, the position between them and the position in relation to the heater 24 in the air passage 24 is always determined in a desired manner, making it easy to assemble. There is no variation, the operating point is stable, and a homogeneous product can be obtained.

The center of the overtemperature rise preventer 50 is allowed to fall into a notch 61 recessed in the cross-shaped heater bobbin 60 around which the heater wire 59 is wound. The notch 61 is located as close to the center of the hot atmosphere as possible to ensure its operation is sensitive and stable, and the notch 61 is formed between the heater wires 59 and is evenly spaced from the heater wires on both sides. is set in a heat-affected position to further ensure its operation.

The heater is divided into two heat generating units and connected in series, and by operating switches _S1 and _S2 , the energization of one heat generating unit and both heat generating units can be switched, and the wattage can be changed. ing.

The heat generating unit that is energized with high wattage is arranged on the downstream side of the airflow so as to thermally protect the blower case 27 and the like on the upstream side, and the heat-sensitive controller is arranged on the downstream side. 49
It also corresponds to the overheat prevention device 50 and serves as a position to improve the thermal influence of the high wattage part and ensure its operation.

As explained above, according to this invention, when the hose is stored in the hose storage part, one end of the opening is exposed to the cord storage part, so that the cord stored in a bundle can be stored inside the hose opening. This has the effect that it can be partially expanded, making it easier to store it, and making effective use of a small space.
