Description

Steam generation unit and steam cleaner

The present invention relates to a steam generating unit and a steam cleaner that provides a heat sink to the electronic pump to release the heat or the surrounding heat generated from the electronic pump satisfactorily to suppress the irregular operation of the electronic pump according to the heat deformation.

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, which hinders the regular movement of the pump due to thermal deformation. .

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 5. 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. 8, 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, 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, as shown in FIG. 5, the housing 310 may be provided with handle rod mounting portions 510A and 510B on which the handle rod 510 is mounted.

Each of the handle bar mounting groove 510A and the handle bar mounting groove 510B has a concave arc-shaped locking jaw 511 to which the lower end of the handle bar 510 is formed. 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, protruding ribs 513 are formed on the inner circumferential surface of the handle bar mounting groove 510A and the handle bar mounting groove 510B to discharge heat to the outside through the handle bar mounting parts 510A and 510B.

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.

In addition, the rear housing 330 is preferably formed with a drawing hole 410 for drawing the power cable 400. The outlet hole 410 may also function as a passage for extracting heat emitted from the heat sink 370 to the outside.

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).

FIG. 8 is a perspective view illustrating an instantaneous heated steam boiler according to the present invention, and FIGS. 9 and 10 are perspective views in which main parts of the instantaneous heated steam boiler of FIG. 8 are separated and combined.

As shown in FIGS. 8 to 10, the instantaneous heating steam boiler 350 includes a U-shaped electric heater 353, a first flow passage 355 and a second disposed on the bottom and top 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. 11 to 13 may be used in various forms.

The flow path tube 355A or 357A of FIG. 11 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. 12 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. 13, 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 some cross-sections of FIG. 13, since the vortex phenomenon occurs in the stepped portion S whose inner diameter changes, the stagnation is prevented from immediately exiting, and thus, time may be lengthened, thereby greatly contributing to vaporization or steaming.

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

The electrical circuit of the steam boiler 350, the electronic pump 360 and the power cable 400 will be described.

The terminal P1 of the specific temperature maintaining bimetal 352 of the steam boiler 350 is connected to the terminal P1 of the electric heater 353 by an electric wire (not shown), and the specific temperature maintaining bimetal of the steam boiler 350 is connected.

In addition, the power cable 400 is connected to the PCB (385).

Referring to the operation principle of the steam cleaner of the present embodiment constituting such an electric circuit as follows.

When the power button 381 is pressed after the cord of the power cable 400 is connected to an outlet, power is applied to the bimetal 352 and the bimetal 352 'through the circuit of the PCB 385.

The bimetal 352 'to which power is applied serves only as a switch for starting the electronic pump 360, and the started electronic pump 360 sucks water from the water tank 380 and continues to supply the steam boiler 350. .

The supplied water flows through the first flow passage 355 and the first steam comes out, and the first steam flows through the second tube 357 through the connection tube 356. A second steam is supplied to the steam sprayer (not shown).

On the other hand, the bimetal 352 'to which power is applied serves as a switch so as to be within a specific temperature range while sensing the temperature of the electric heater 353.
