Description

Housing for steam cleaner {housing for steam cleaner}

The present invention relates to a steam cleaner housing in which a power cord housing is detachably installed at a rear housing.

As a housing for a conventional steam cleaner, for example, the one disclosed in Japanese Patent No. 10-0813537 is proposed. The steam cleaner housing of this publication is composed of a front housing and a rear housing, and the rear housing is integrally formed with a mounting chamber in which a power cord and a water tank detaching device are mounted.

Therefore, in order to secure the fastening space between the rear housing and the front housing, a housing having a wide width direction is formed, which can give a feeling of not slimming as a whole.

In addition, the housing of the above publication is coupled to the front housing and the rear housing, the upper end of the rear housing is provided with a pipe is inserted into the handle rod is installed. Since the pipe is installed on top of the rear housing, it is thicker than the thickness of the front housing, which makes the overall feeling large.

In addition, the water tank detachment device for the vacuum cleaner of the above publication is composed of a coupling protrusion mounted on the bucket and a pusher mounted on the push rod assembly to push the coupling protrusion, wherein the pusher wraps the outside and the inner side of the guide protruding from the push rod assembly. A dome shaped button, a release preventing piece for preventing the release of the button and the pushing piece, and a spring interposed between the release preventing piece and the pushing piece.

By the way, this configuration is a double structure to push the engaging projection to the push portion, the button and the push piece on the small working line should be pressed with a force greater than the elastic force of the spring.

Meanwhile, the conventional steam cleaner is provided with a cord hanger member on the handle and the housing. In particular, the cord hanger member installed in the housing is installed on the side or the back, the appearance is not good when installed on the side, when installed on the back, the lower cord hanger member is likely to be broken first because the housing first touches the floor.

On the other hand, it is proposed as a joint structure of a conventional steam cleaner disclosed in the publication of Korea Patent Utility Model No. 20-0392095. Conventional steam cleaner is composed of a water tank 10 to supply water with the function of the push rod as shown in Figure 28, the heating water tank 40, the cover (not shown) and the bottom plate 60 to form a main body. A handle supporting member (not shown) is formed at an upper portion of the bucket 10, and a fitting cylinder 14 is formed at a lower portion thereof. The handle supporting member 12 is fitted with a handle member so that the handle member and the water bottle 10 together function as a pusher. The cylindrical body 20 is integrally formed with a hinge axis (not shown) to form the same center on both sides, the fitting groove (not shown) to be perpendicular to the center is penetrated, it is coupled to the cylindrical guide (30). And the fitting groove (not shown) is coupled to the outlet guide cylinder 26, the outlet guide cylinder 26, the fitting cylinder 14 of the water bottle 10 is closely fitted, the opposite side to the outlet port (28) is naturally formed.

However, since the fitting cylinder 14 is fitted to the outlet guide cylinder 26, there is a risk of being damaged by receiving the shear force and rotation moment in particular at the boundary between the bucket 10 and the outlet guide cylinder 26 when cleaning. Big.

This phenomenon is likely to break the fitting cylinder 14 in the joint structure as in the prior art because the weight is concentrated on the boundary portion when the steam generating unit is mounted on the side that serves as a pusher and when the housing is separated and coupled. .

On the other hand, since the conventional steam heating steam cleaner is equipped with an electromagnetic pump and the steam heating steam boiler in a housing having a single mounting chamber, the heat generated by the steam boiler affects the electronic pump so that regular movement of the pump is performed according to thermal deformation. Inhibit. Therefore, the water discharge amount of the electronic pump is irregular, so that the durability and steam injection efficiency of the electronic pump are poor.

In order to solve this problem, the one disclosed in Japanese Patent Laid-Open No. 9-192147 is proposed as a conventional steam boiler. That is, as shown in FIG. 29, the sensor 6 which senses the temperature of the steam boiler 5 is controlled by the intermittent operation of the electronic pump 9 through the control circuit 8 (microcomputer) and at the same time U is controlled. The current of the magnetic electric heater 5b is adjusted to control the heat generation thereof.

However, since the additional elements such as the temperature sensor 6 and the control circuit 8 must be provided, the cost is much higher than the mechanical electric steam boiler having only the bimetal for starting the electronic pump and the bimetal for maintaining a specific temperature range of the heater. There is a limit to this (especially the cost of the control circuit is relatively very high).

In addition, as shown in FIG. 29, the steam boiler 5 includes a block 5c, a spiral flow path 5a through which the washing water 3 is supplied, and a spiral flow path. It consists of the U-shaped electric heater 5b located close to the inside of 5a. The water supply pipe 4 and the steam pipe 7 are connected to the water inlet and the steam outlet of the flow path 5a.

However, since the flow path 5a is a spiral shape wound around the outside of the electric heater 5b, the volume of the block 5c is increased by the spiral outer diameter, which is an obstacle to the slim modularization of the steam generating unit, and thus does not contribute to the compactness of the device. can not do it.

On the other hand, as shown in Figure 30, the surface of the bottom plate 15 is formed with a steam injection port 15 protruding upwards, the steam supply tube 16 is connected to the steam injection port (15).

However, since the steam injection port 15 protrudes upward, in order to bend the steam supply tube 16 without bending it (steam sprays well), the inflection point A, which is the highest point of the steam supply tube, as shown in FIG. The position is considerably higher than the upper end of the steam injection port (15). Therefore, the height H up to the surface of the bottom plate 15 and the highest inflection point A of the tube 16 is very high.

This height (H) also significantly increases the overall height of the main body 110, the loss of material is large, it is difficult to insert the main body in a narrow gap, etc., the place for steam cleaning is limited.

The present invention has been made in view of the above-described problem, an object of the present invention is to provide a housing for a steam cleaner that can implement a slimmer product while ensuring a sufficient fastening force of the rear housing and the front housing.

In order to achieve the above object, the housing for a steam cleaner according to claim 1 of the present invention,

The hinge cover 140 is installed on the upper cover 120. Since the installation structure of the hinge member 140 is described in detail in Korean Patent Application Publication No. 10-0793414 filed by the present applicant, detailed description thereof will be omitted.

3 and 7 to 9, the hinge member 140 includes a connecting pipe 141, hinge shafts 142 formed on both sides of the connecting pipe 141, and the connecting pipe 141. Consists of the fitting groove 143 formed on the outer peripheral surface of the.

The connection tube 141 is inserted into the fitting protrusion tube 311 described below, and the fitting groove 143 is fitted to the free end side of the fitting protrusion tube 311 and coupled thereto.

Accordingly, the force applied to the fitting protrusion tube 311 by functioning as a core according to the insertion of the fitting protrusion tube 311 while preventing the rear and front fitting protrusion tubes 311a and 311b from spreading. Durability can be improved by acting with great reaction force against.

8, the insertion length b of the connection pipe 141 is preferably longer than the length a of the fitting protrusion pipe 311.

In this case, when the length is longer (a <b), the connection tube 141 sufficiently supports the boundary between the housing 310 and the fitting protrusion tube 311, thereby significantly reducing the risk of damage to the fitting protrusion tube 311. Can be reduced.

In addition, it is preferable that a stepped portion 313 that is caught by the free end 143a of the fitting groove 143 is formed at the front end side of the fitting protrusion pipe 311. The outer circumferential surfaces of the fitting protrusion pipe 311 and the fitting groove 143 meet in a straight form and are beautiful in appearance, and can prevent the stepped portion 313 from being forcibly inserted into the stopper and being damaged.

In addition, the rear and front housings 330 and 320 are preferably provided with stoppers 315a and 315b to which the free end 141a of the connection pipe 141 is caught.

This rotational force lifts the operating shaft 275 upward and thus the bucket 380 because the locking piece 231a is pulled out of the locking groove 382 when the slider 231 rises in the opposite direction to the elastic force of the elastic part 250. Can be removed.

After removing the water tank 380 and release the push button 211, the locking piece (231a) is out of the hole 291 by the elastic force. When mounting the water container 380, just push it in, while pushing up the inclined surface of the locking piece 231a so that the locking piece 231a is inserted and locked again at the position of the locking groove 382.

By the configuration of the cam portion 270 in this way, the operation is surely performed even when pressed with a small force, so the operation is easy and convenient.

In addition, since only the structure of the locking groove 382 of the bucket 380 may be provided, the structure may be simplified.

On the other hand, the power cord housing 600 is preferably installed detachably to the rear housing (330).

Although the power cord housing 600 may be integrally formed in the rear housing 330, the fastening hole 601 for fastening the rear housing 330 and the front housing 320 should be moved outward from both sides of the position of FIG. 13. As a result, the width of the housing 310 may be increased, thereby increasing the volume of the entire housing 310, thereby providing a factor that hinders slimming.

The power cord housing 600 is provided with a power cord support hole 630 and a power cord accommodation groove 632.

The power cord support hole 630 is a support hole into which the hard power cable 400 is inserted when the wire is inserted from the top to the bottom, and the wire comes out through the power cord accommodation groove 632 into the outlet hole 410. Is connected to the PCB 385.

In particular, the groove 650 is formed in the rear housing 320, and the drawing hole 410 is preferably formed on the groove 650.

The groove 650 is formed at a position corresponding to the power cord accommodation groove 632, and can accommodate the electric wire without deepening the depth of the power cord accommodation groove 632.

In addition, it is preferable that the pressing pieces 654 and 634 are formed in the groove 650 and the power cord accommodation groove 632 so that the wire does not move up and down or left and right. This structure can surely prevent the hard wave wire 400 from falling up.

In addition, a locking hole 636 is formed in the power cord housing 600, and a locking hook 656 is formed in the rear housing 330. The locking hook 656 has a 'b' shape.

Accordingly, the locking hole 636 is pushed to the locking hook 656 and pulled from the top to be stuck.

The power cord receiving groove 632 is firmly fixed to the rear housing 330 through the fastening portions 638 and 658.

The steam boiler 350 and the electronic pump 360 are mounted in the steam boiler mounting chamber 350A and the electronic pump mounting chamber 360A of the rear housing 330 as shown in FIG.

The rear housing 330 is provided with a partition wall 390A for separating the steam boiler mounting chamber 350A and the electronic pump mounting chamber 360A. At this time, it is preferable that the steam boiler mounting chamber 350A is disposed below the partition wall 390A, and the electronic pump mounting chamber 360A is disposed above.

In addition, as shown in FIG. 12, the barrier ribs 390A are preferably provided with passage grooves 391 and 393 through which the suction tube (not shown) and the discharge tube (not shown) of the electron pump 360 pass.

Similarly, it is preferable that the steam boiler mounting cover chamber 350B and the electromagnetic pump mounting cover chamber 360B are formed in the front housing 320 to cover the rear housing 330. Of course, when the partition wall 390A does not protrude, it is preferable that the partition wall 390B corresponding to the partition wall 390A is formed in the front housing 320.

By the configuration of the barrier rib 390A or the barrier ribs 390A and 390B, heat generation of the steam boiler 350 is blocked, and thus the pump can be stably pumped without affecting the electron pump 360.

In the present embodiment, the steam boiler 350 and the electron pump 360 are mounted on the rear housing 330 having the steam boiler mounting chamber 350A, the electronic pump mounting chamber 360A, and the partition wall 390A. It may function as a main housing, and the front housing 320 may serve as a cover of the rear housing 330 to function as an auxiliary housing. If the power button 382 is at the rear of the rear housing 330, on the contrary, the front housing 320 functions as the main housing.

In addition, the heat dissipation hole 331 is preferably formed in the rear housing 330 having the steam boiler mounting chamber 350A, as shown in FIGS. 2 and 12. Since the heat dissipation hole 331 emits heat generated by the steam boiler 350 to the outside, heat transfer to the electron pump 360 may be further blocked.

As such, since the structure capable of maximally suppressing defects due to thermal deformation of the electronic pump 360 is adopted, an inexpensive mechanical steam boiler 350 can be adopted.

As shown in FIG. 20, the mechanical steam boiler 350 is a starting temperature bimetal 352 ′ of the electronic pump 360 and a temperature maintaining bimetal 352 of the steam boiler 350 without using a temperature sensor and a control circuit. It is an instant heated electric boiler (350).

On the other hand, in order to quickly release the heat generated from the electronic pump 360 itself, the heat sink 370 is preferably mounted. As shown in FIGS. 18 and 19, the heat sink 370 includes the bottom base 371, the side wall base 373, and the side wall base 373 to form a space in which the casing 361 of the electron pump 360 is seated. The heat dissipation fin 375 is formed on the outer wall.

The heat sink 370 on which the electron pump 360 is mounted is mounted in the electron pump mounting chamber 360A. That is, the discharge hole 365 of the electron pump 360 is supported by the support hole 334 of the fixing bracket 333 fixed to the rear housing 330, and the suction hole 363 of the electron pump 360 is the rear housing 330. By being supported by the fastening bracket 335 fastened to the), the electronic pump 360 is fixed in the form of pressing the heat sink 370 down.

As shown in FIG. 11, the fastening bracket 335 includes an inlet support piece 337 supporting the inlet 363 and a fastening piece 338 fastened to the fastener 339 formed at the rear housing 330. It is a 'b' shape.

On the other hand, the heat sink 370 is preferably formed with an arrangement groove 377 is disposed protruding fixing bracket 333. In addition, it is preferable that the engaging jaw 335 is applied to the front surface of the heat sink 370 in the electronic pump mounting chamber 360A.

The placement groove 377 and the locking jaw 335 have a function of determining a position when the heat sink 370 is seated, so that assembly efficiency is good.

In addition, the housing 310 is preferably formed with a handle rod mounting portion 316 to which the handle bar 510 is mounted, as shown in FIG. 12.

The handle rod mounting portion 316 is handle mounting pipes 316a and 316b formed inside the housing 310 and handle mounting protrusion pipes 316a 'protruding upward from the upper ends of the handle mounting pipes 316a and 316b. 316b '.

In particular, since the handle-mounted protrusion pipes 316a 'and 316b' protrude integrally from the rear housing 330 and the front housing 320 in a semicircular shape, the overall thickness of the housing 310 can be reduced.

Each of the handle bar mounting pipes 316a and 316b has a concave arc-shaped locking jaw 511 to which the lower end of the handle bar 510 is caught. The concave arc-shaped latching jaw 511 serves as a passage through which heat in the electron pump mounting chamber 360A easily escapes upwards.

In addition, a protruding rib 513 is formed on each inner circumferential surface of each of the handle bar mounting pipes 316a and 316b to allow the handle bar mounting pipe 316 to discharge heat to the outside.

The handle mounting protrusion pipes 316a 'and 316b' are provided with fastening holes 318a and 318b to which push buttons (not shown) of the handle bar 510 are fastened.

In addition, the handle mounting protrusion pipe (316a ') (316b') is preferably provided with a gap preventing member 319.

That is, the gap preventing member 319 can be reliably prevented from spreading with each other by mounting the band-type ring by pressing the band-type ring, so that the handle-mounted protrusion pipes 316a 'and 316b' which are opposed to each other are not fastened.

In addition, it is preferable that the gap preventing member 319 is press-fitted into the stepped portions 317a and 317b formed at the free ends of the handle mounting protrusion pipes 316a 'and 316b'.

Thus, the handle rod mounting protrusion pipes 316a 'and 316b' protruding in a semicircular shape from the rear housing 330 and the front housing 320 are formed, and inserted into the gap preventing member 319 to prevent the housing 310 from being disposed. While reducing the thickness to realize overall slimming, the tightening force between the rear housing 330 and the front housing 320 is strengthened to firmly prevent the opening of the housing 310 even when the handle bar 510 is shaken.

In addition, the handle bar 510 functions as a heat conductor that absorbs heat emitted from the heat sink 370 and releases it to the outside when an aluminum material having excellent heat conductivity is used.

The push rod assembly 500 is composed of a handle bar 510 and a handle 530. In addition, the push rod assembly 500 is provided with the upper and lower cord hook members (540, 550).

In particular, the upper cord hanger member 540 is installed on the handle 530, the lower cord hanger member 550 is installed on the handle bar 510.

The lower cord hanger member 550 is installed on the handle bar 510, which is neat compared to the side cord or the rear surface of the housing 310, and is spaced between the upper cord hanger member 540 and the lower cord hanger member 550. It can be kept constant so that when the cord is wound around the elliptical well, especially when the lower cord hanger member 550 is installed on the back, the lower cord hanger member 550 hits the floor and breaks when the housing 310 collides with the floor. There is concern.

In addition, the upper cord hanger member 540 may be installed on the handle bar 510.

26 and 27, the lower cord hanger member 550 includes a cord hanger 560, a cord hanger support 570 for supporting the cord hanger 560, and a cord hanger support 570. It consists of a positioning member 580 for determining the position of the cord hanger 560 with respect to.

The cord hanger 560 is composed of a cord hanger tube 563 having a through hole 561 and a lever type cord break prevention piece 565 formed on the outer side of the cord hanger tube 563.

The cable is wound around the cord hanger tube 563, and the cord escape prevention piece 565 functions as the coiled cable is pulled out while being superimposed.

Cord hanger support portion 570 is fitted tube 571 to be fitted to the outer circumferential surface with the fastening hole 512 of the handle rod 510, the insertion hole 573 protruding from the fitting tube 571 is inserted into the through hole 561. It consists of).

The fitting pipe 571 is formed with a fastening hole 572 communicating with the fastening hole 512, and a fastening female screw 574 is also formed in the insertion hole 573.

The piece 575 is fastened to the female screw 574 to support the cord hanger support part 570 on the handle bar 510.

The positioning member 580 includes positioning grooves 581a and 583a formed in the fitting pipe 571, positioning protrusions 581b and 583b formed in the cord hanger tube 563, and one end of the cord hanger tube. A spring 585 fitted to the insertion hole 573 while being supported by the seating jaw 562 of the 563, and a fastening piece 587 with a washer fastened to the insertion hole 573 to support the other end of the spring 585. Consists of.

Therefore, since the spring 585 applies the elastic force toward the handle bar 510, the engagement between the positioning members 580 is performed reliably.

In the case where the positioning grooves 581a and the positioning protrusions 581b are engaged with each other, it is a position where the cord can be wound as shown in FIG. 27, and the positioning grooves 581a and the positioning protrusions 583b are engaged with each other. There is a cord departure prevention piece 565 facing upwards can be unwrapped cord.

In this position change, when the cord hanger 560 is pulled and turned to the opposite direction of the elastic force, the engagement between the positioning members 580 is changed at intervals of 180 degrees.

Since the cord hanger member 550 is installed on the handle bar 510 in this way, even if it is collapsed on the floor, the bulky housing touches the first to prevent damage to the cord hanger member 550 and is not installed on the side of the same handle. The cord hanger member 550 is installed on the line of the push rod assembly 500 such as the 530 and the handle bar 510, and the design is excellent.

Electron pump 360 is a pump for pumping by reciprocating the plunger by the electromagnetic force, its operation principle and configuration refer to the publications of Korean Patent Laid-Open No. 2000-73549 and Korean Patent No. 10-747431, detailed description thereof will be omitted. .

The water suction port 363 of the electronic pump 360 is connected to the water tank 380 by a tube (not shown), and the water discharge port 365 of the electronic pump 360 is the water injection hole 355a of the steam boiler 350. Is connected by a tube (not shown).

20 is a perspective view of the instantaneous heating steam boiler according to the present invention, Figures 21 and 22 are perspective views in which the main portion of the instantaneous heating steam boiler of Figure 20 separated and combined.

As shown in FIGS. 20 to 22, the instantaneous heating steam boiler 350 includes a U-shaped electric heater 353, a first flow channel 355 and a second disposed on the lower surface and the upper surface of the electric heater 353. The flow path tube 357 and the block 351 which embed | buried these are comprised.

The first flow pipe 355 is the first water injection pipe (355a), the first steam discharge pipe (355c), the first water injection pipe (355a) and the first connection pipe (355b) connecting the first steam discharge pipe (355c) is It is formed integrally.

Similarly to the first flow pipe 355, the second flow pipe 357 is connected to the first steam discharge pipe 355c by the connecting tube 356, and the second steam discharge pipe 357a and the second steam discharge pipe 357c. In addition, a second connection pipe 357b connecting the second steam injection pipe 357a and the second steam discharge pipe 357c is integrally formed.

The first flow path 355 and the second flow path 357 are arranged on the same plane as the plane (X-Y plane) of the electric heater 353.

Therefore, the two-dimensional flow path pipes 355 and 357 can be made thinner than the surface area of the block 351, compared to the conventional three-dimensional spiral flow pipe, making the steam boiler 350 slimmer. Can be implemented.

Meanwhile, the first connector 355b and the second connector 357b are preferably formed to be bent in a wave form. This is for realizing complete steaming (with little or no liquid) by lengthening the contact time of the electric heater 353 while reducing the volume.

In addition, the flow path tube formed integrally can be be divided into the first flow path pipe 355 and the second flow path pipe 357, but the first flow path pipe 355 and the second flow path pipe 357 into two After dividing and embedding in the block 351 and connecting with the connecting tube 356, the air filled with steam is very finely released from the connection between the connecting tube 356 and the pipes 355c and 357a. Very low noise during injection, regular injection volume and significant contribution to complete steaming.

On the other hand, instead of using two upper and lower flow channels, the single flow tubes shown in Figs. 23 to 25 may be used in various forms.

The flow path tube 355A or 357A of FIG. 23 has the shape bent by inserting the coil-shaped heating body 356A in the tube.

Since the heating element 356A functions as a heat conductor that receives heat from the flow path tube 355A or 357A, the heating body 356A expands the surface area in contact with the water flowing in the flow path tube 355A or 357A to vaporize or steam the water. Play a big role.

The heater 356A may have any shape in addition to the coil shape, as long as the surface area in contact with water is widened.

The flow path tube 355B or 357B in FIG. 24 may form a tread 356B pressed against the connecting tube. Since the depressed mark 356B protrudes into the flow path tube 355B or 357B by the depressed amount, this protruding can interfere with the flow of water and lengthen the stagnation time, thereby greatly contributing to vaporization or steaming.

In the flow path pipe 355C or 357C of FIG. 25, the inner diameter φ 1 of the water injection pipe may be larger than the inner diameter φ 2 of the steam discharge pipe.

As shown in a partial cross section of FIG. 25, since the vortex phenomenon occurs in the stepped portion S in which the inner diameter is changed and stagnates so that it does not immediately exit, the time can be lengthened, thereby greatly contributing to vaporization or steaming.

The difference in the inner diameter is preferably formed through expansion or shaft work.
