Description

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

This invention will be described below with reference to 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 retaining 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.

Reference numeral 9 designates a handle that is integrally formed on the upper part of both cases 2 and 3 and is completed when the two are combined, and reference numeral 10 represents 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. ,
Two are the air mat storage parts 12 in the rectangular parallelepiped space located at the bottom of this hose storage part, and three are the hose storage parts 11.
This is a vertical cord storage section 13 whose upper space extends to the right end surface of the cord storage section 13.

The wall forming the lower right half of the hose storage section 11, the right side of the air mattress 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 section 11 has a semicircular cross section, but the center of curvature is offset by one dimension in the middle.

In other words, the center of the deviation forms a step 15 at the deviation part.

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

During such storage, the ridges of the bellows part 18 of the hose 16 fit into the step 15, which helps to keep the entire hose in place, and since the step 15 is formed on the opposite side, the winding of the bellows part 18 of the hose is prevented. It matches the direction of rotation and is given extremely convenient consideration.

A half-ring-shaped barrier 19 is provided protrudingly between the right end of the hose storage section 11 and the cord storage section 13, and the end surface of the one end connecting section 17 of the hose 16 hits this barrier, allowing the cord storage. It is prevented from protruding toward the portion 13 side.

The protruding width of this partition wall is set to such a size that it blocks the end face of the hose connecting portion 17, but hardly blocks the cylindrical space.

For this reason, the cords 20 appropriately bundled in the cord storage section 13
When the cord 20 is stored, 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, which improves the ability to hold the cord and prevents stress from being placed on the cord. This cord storage section 13 can be made as small as possible.

The cords 30 are led out from the lower part of the cord storage part 13, so that the cords in the bundled state are placed in a position where the upper and lower portions of the cords receive a holding force, so that they can be properly placed.

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

These ribs are provided in opposing protrusions from the upper and lower walls of the hose storage section in two pairs on the left and right in correspondence with the hose connection parts 17, and when one or both of the connection parts 17 are firmly held between the ribs 21, When 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 rib 21, a part of the connecting portion 17 is made to avoid the claw portion 7 of the front case 3. It is set so as to face the claw portion 7 position of No. 3.

As a result, if the hose 16 is not stored properly,
The retaining piece 8 of the front cover 4 is blocked between the lower edge of the claw part 7 of the front case 3 and the outer surface of the hose connection part 17, and the claw part 8A of the front cover 4 and the claw part 7 of the front case 3 are held together. Since the front cover 4 is not attached to the front case 3 until the hose 16 is re-stored in its normal position, the proper storage is always performed.
This eliminates strain on each part.

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 extended position so that the end thereof is folded back. A free end, and a claw portion 8A on the midway upper surface of the folded portion.
When the retaining piece 8 is compressed, the claw part 8A escapes to the free end side, and the free end is stopped on the extended base of the engaging piece 8, creating tension and engaging operation. is against.

When the hose 16 is properly accommodated and maintained 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 its longitudinal direction, causing elastic recovery of the bellows portion. The force acts to help hold the hose 16 in a more secure direction.

Reference numeral 22 denotes a hot air generator, which is separated from the motor M, the blower 23, the heater 24, and the wind cylinder 26 for forming a series of air passages 25 between them.

The wind body 26 is constructed by joining a synthetic resin blower case 27 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 remainder 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, since this storage part is semicircular, there is a sufficient gap 3 between the flat plate member 30 and the back surface of the hose storage part.
1 is formed.

This gap has the effect of reducing heat transfer from the heater case 27 to the hose housing part 11, and has the effect of protecting the hose housing part 11, etc., which is integrally molded from synthetic resin, from the adverse effects of heat. On the contrary, it allows the two to be placed close together, making a compact design possible.

Moreover, for the hose storage section 11 having a relatively long length,
The convenient arrangement of the heater case 28 having a similar length contributes to the realization of the above-mentioned compact design. This is sufficiently eliminated by the gap 31 that is largely formed by the semicircular cross section that matches the semicircle.

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,
It is integrally formed to fit into a space formed outside the circular bulge of the blower case 27 and the lower surface of the wind barrel 26.

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, air mats are made of a flexible, thin cloth-like material.
Therefore, since it can be folded freely and is generally folded regularly into a substantially rectangular shape, the width of the air mattress storage section 12 is not required to be large.
The dimensions limited by the bulge of the case are sufficient;
In this way, consideration of the function of each part and the required size of storage space, as well as careful consideration of the positional relationship, greatly contributes to the compact overall structure.

The air mat 32 is inserted between the comforter 33 and the mattress 34, is connected to the other end of the hose 16 connected to the end of the air path 25 of the hot air generator 22, and is inflated into a predetermined shape by introducing warm air. It also has the ability to blow air 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.

A hose connecting portion 17 is in charge of connecting the air mat to the end of the air passage 22.

Therefore, a cylindrical air outlet 35 is provided on the end surface of the heater case 28.
A connection part 17 of the hose fits into this outlet, and an introduction port 36 is formed in a part of the air mat 32, and the other connection part 17 of the hose 16 fits into this introduction port 36.
This configuration is connected to the air mattress 32, thereby introducing warm air into the air mattress 32.

This warm air is generated by heat exchange by the heater 24, and the air flow is caused by the outside air flowing into the main body from outside the main body 1 and the motor M or the blower case 2.
Enters the blower 23 from the 7 side, passes through the air path 25, and reaches the air outlet 3.
5.

An air intake hole 36 is provided in the front cover 4 to introduce outside air, and its position corresponds to the back wall 37 of the motor housing 14. An air introduction hole 38 is provided for guiding outside air taken in from the intake hole 36 to the blower 23.

Further, another air intake hole 39 is provided in the rear case 2 in correspondence with the air mattress storage section 12, and serves as an aid when the air intake hole 36 is accidentally blocked.

A rectangular closed 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 closed by a box-shaped cover 41 made of synthetic resin, and therefore a notch 42 and a raised part 43 are formed on the opposite edges of the opening 40, and the cover 41 has a notch 42 and a raised part 43 on the lower surface of the notch 42. Engaging protrusion 44 and cut-and-raised portion 4
The mounting hole 46 corresponds to the screw hole 45 formed in the horizontal part of 3.
A mounting screw 47 inserted through this mounting hole is screwed into the tapped hole 45 to form a closed connection.

The cover 41 has a predetermined depth so that the opening 4
0 is closed, a chamber 48 is formed on the side of the air passage 25 that communicates with this air passage, and a reset type thermal controller 49 and an overtemperature rise preventer 50 are installed on this room side.

The overtemperature rise preventer 50 is supported by inserting lead wires at both ends 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 and the cylindrical stator 53.
The stator is inserted and held in the hollow of the boss 51.

That is, the connection is made by crushing the stator 53, and the boss 51 is formed with an insertion hole 54 for the connection wire 52 and a holding hole 55 with a larger diameter than the insertion hole 54, into which the fixing device 53 is inserted. It is held and fixed by being stopped by a step formed at the boundary with the small-diameter insertion hole 54.

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 such that it is positioned within the recess so that it is not operated unnecessarily.

This reset button position is near the air intake hole 39, and it always tends to cool under the influence of air flow, so it does not overheat, and the outer surface of the cover 41 is similarly cooled, and the synthetic resin The cover is protected from heat.

The cover 41 is also attached to the side wall of the heater case 27, and the heat sensitive controller 49 and the overtemperature rise preventer 50 are attached to the heater case 27.
It is set at a position where it is affected by temperature in the lateral direction relative to 4, 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 operates quickly, and when placed on the bottom surface, the effect of heat is small and the operation is delayed, which is dangerous. In this case, the operating point becomes 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.

This arrangement inevitably causes the reset button 56 to protrude from the side of the main body, which has the advantage of further improving its operability compared to the conventional button 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 air path 2 are
The position in relation to the heater 24 within the heater 24 is always determined in a desired manner, there is no assembly variation, the operating point is stable, and a homogeneous product can be obtained.

The temperature overrise preventer 50 is allowed to fall into the 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 thermal atmosphere as possible to ensure its operation is sensitive and stable.Moreover, the notch 61 is formed between the heater wires 59, and is evenly spaced from the heater wires on both sides. Set in a heat-affected position to further ensure its operation.

The heater is divided into two parts as a unit of heat generation and connected in series, and switches S1. By operating S2, the energization of one heat generating unit and both heat generating units is switched.
It is possible to switch the wattage.

The heat generating unit that is energized with high wattage is arranged on the downstream side of the air flow, and is arranged so as to thermally protect the blower case 27 on the upstream side, and the heat-sensitive control unit on the downstream side. This position corresponds to the device 49 and the overheat prevention device 50, and it also 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, the hose storage section has a step formed by offsetting the axis in the middle thereof, and a rib extending perpendicularly to the axis direction is provided on the opposite wall. The hose is held securely by the ribs, and the hose itself bends slightly in the longitudinal direction in the stored state, so that it can be held more reliably by the restoring force of the hose itself.
