Description

Steam occurrence is swift and Steam squirt pressure is improved Steam Cleaner}

The present invention relates to a steam cleaner, and more particularly, to an improved steam cleaner to promote rapid steam generation and to eject steam at a high steam ejection pressure, thereby greatly improving steam cleaning efficiency.

In general, it is already known that a steam cleaner has a structure that generates steam by heating water by a heater.

However, the steam cleaner system that heats water by the heater is not only structurally difficult to generate steam quickly, but also difficult to cause steam to be ejected at a relatively high steam ejection pressure. In addition, since the steam ejection pressure is low, only a steam cleaner mainly for home use is being released.

In the prior art, a steam cleaner such as Korean Patent No. 10-0734568 has been disclosed. However, since only a heater is used, there is a disadvantage in that a lot of battery energy is consumed for heating water and steam is not generated at an early stage of operation.

In addition, in the case of a steam cleaner, such as the Republic of Korea Patent Registration No. 10-0779187, since the steam module is to generate steam in the boiler, it takes a long time to adjust the steam temperature and thereby causes a lot of electrical energy consumption. It is becoming.

In addition, the steam cleaner, such as the Republic of Korea Patent No. 10-0920029 has a disadvantage that the steam generating unit is made of only the heater and the pipe, so that the steam generating space is narrow, so that a large amount of steam is difficult to be generated, which reduces the steam cleaning efficiency.

And in the instantaneous heating steam cleaner, such as the Republic of Korea Patent No. 10-0727526, some of the first generated steam is stored in the water tank to immediately clean the steam without preheating, but the structure is complicated and some steam is separated into the water tank Since the remaining steam is supplied and the remaining steam is ejected, the steam ejection pressure is lowered, and the steam cleaning efficiency is lowered.

Therefore, the above-mentioned prior arts have a problem in that the steam generation is not rapid and the steam ejection pressure is lowered. Therefore, the above-mentioned prior arts have a limited problem in use, which can only be used in household steam cleaners.

Therefore, for example, steam cleaners such as the prior art, which have slow steam generation and low steam ejection pressure, are difficult to clean and clean dirt or dust, such as dust or dirt, that are difficult to clean. This falling problem is caused.

This led to the study of a multi-purpose steam cleaner that can be used not only for home use but also for special purposes such as cleaning the inside of an air conditioner.

When the present invention is described in more detail based on the accompanying preferred embodiments as follows.

1 to 3, the present invention includes an inner bucket 2 provided inside the case 1 and an outer bucket 3 provided outside, and the inner and outer buckets 2 and 3. Are respectively connected to the water supply module 10 by the internal connection hose 4 and the external connection hose 5, respectively.

Referring to FIG. 3, the water supply module 10 includes a first connector 11 and a second connector 12, respectively.

Therefore, when supplying the water (W) water supply module 10 of the inner bucket (2), as shown in (a) of FIG. 3, the first and second connectors 11 and 12 are connected to the inner hose 4. To be.

However, when the water (W) of the outer bucket (3) is to be supplied to the water supply module 10, the inner connecting hose (4) is separated from the first and second connecting parts (11, 12) and then (b) of FIG. As described above, the external connection hose 5 is connected to the second connection part 12.

In the case of using the inner bucket (2) is to be used when the cleaning is possible only with a small amount of steam (S) at the time of steam cleaning, it is preferable to move the steam cleaning at home mainly because it is convenient to move.

And when using the external bucket (3) is to use when a large amount of steam (S) is required, because it is used when the use time of the steam cleaner is long or insufficient water (W) of the inner bucket (2) It is desirable when special purpose steam cleaning is needed.

On the other hand, in the connection of the internal and external connection hoses 4 and 5 and the first and second connection parts 11 and 12 of the water supply module 10, there are check valves (not shown). When the internal and external connection hoses 4 and 5 are connected to the first and second connection parts 11 and 12, the connection ports (not shown) of the first and second connection parts 11 and 12 are automatically opened.

In addition, when the internal and external connection hoses 4 and 5 are pulled out from the connection ports of the first and second connection parts 11 and 12, the connection ports of the first and second connection parts 11 and 12 are automatically closed. It is not only prevented to flow into the connection port of the first and second connection parts 11 and 12, but also the connection port of the first connection part 11 even when the internal connection hose 4 is separated as shown in the solid line of FIG. Water (W) does not leak out of it.

As described above, since the connection openings of the first and second connection parts 11 and 12 are automatically opened and closed, detailed drawings and descriptions thereof will be omitted. Reference numeral 7 represents a water hose connecting the inner bucket 2 and the first connector 11.

Therefore, the present invention includes a plunger pump 20 for forcibly transferring the water W transferred from the second connector 12 of the water supply module 10 through the water hose 7 '.

4, the plunger pump 20 has a magnetic plunger having a pressurized check valve 24 when power is applied to the induction coil 23 wound on the bobbin 22 installed outside the core 21. 25) is designed to reciprocate.

And both sides of the elastic member (27, 27) inserted into the tube hole (26a) of the rear extension tube portion 26 is formed so that the long trailing tube portion 26 penetrating in close contact with the inner surface of the core inner hole (21a). ') The magnetic plunger 25 having the check valve 24 is installed reciprocally so that water (W) introduced through the inlet nozzle member 28 is discharge nozzle member having the check valve 29 built therein. Is discharged through the 30, the entire body portion 31 except the leading end of the inlet nozzle member 28 and the discharge nozzle member 30 is injection molded to be molded to be covered with a plastic molding member (32) have. Reference numeral 33 denotes a power supply line.

Therefore, in the present invention, when the magnetic plunger 25 moves toward the inlet nozzle member 28, the pressurized check valve 24 opens and water W is ejected to the front, and the magnetic plunger 25 is discharged again. When moving forward in the direction of the nozzle member 30, the pressurized check valve 25 is retracted, forcibly pushing water (W) toward the discharge nozzle member 30 to be discharged, and the magnetic plunger 25 as described above. ) Is continuously reciprocated so that the water (W) is forced to the steam control means 40 through the water hose (7 ").

The plunger pump 20 is molded so that the entire body part 31 except the front end portions of the inlet nozzle member 28 and the discharge nozzle member 30 is insert injection molded to be completely covered with the plastic molding member 32. Safety is ensured because it is not affected by moisture or moisture and no short phenomenon occurs inside.

Therefore, the plunger pump 20 is installed inside the case 1 so as to be supported by each support member 34 on both sides, and between the support member 34 and the case 1, a dustproof rubber member made of silicon ( 35) is placed to reduce the vibration and noise generated by the magnetic plunger 25 reciprocating. Reference numeral 36 denotes a fixed screw.

Referring to Figure 5, the water (W) forcibly transported through the water hose (7 ") by the plunger pump 20 is the copper pipe 42 wound on the heating body 41 of the steam control means 40 After being transferred through, it is intended to flow into the heating body 41.

As shown in FIG. 2, the heating body 41 has a long length in the shape of a rod, and the heating body 41 has a steam generating hole 43 in the longitudinal direction.

In addition, as shown in Figure 6 and 7 is provided with a heater hole 44 is formed toward the upper portion of the steam generating hole 43, the heater hole 44 is to be coupled to the rod heater 45 is fitted. . The heater hole 44 and the rod heater 45 may be provided individually, but it is preferable to be provided in a U-shape as shown in FIG.

In addition, water (W) is introduced into the steam generating hole (43) from the copper pipe (42) through the inlet (43a) as shown in FIG. Reference numeral 43b denotes a connecting nipple.

Therefore, when electrical energy is supplied to the rod heater 45 by the command of the power supply unit control unit 50, the entire heating body 41 is heated by the heat energy generated from the rod heater 45, and thus steam Steam (S) is generated as the water (W) introduced into the generating hole 43 is heated, and the steam generation will be described in more detail later.

Therefore, the present invention can adjust the temperature of the heating body 41 is heated because the temperature of the rod heater 45 can be adjusted in the power supply unit control unit 50.

And the present invention is heated as shown in Figure 9 is wound around the copper pipe 42 is wound around the outer circumferential surface of the heating main body 41 is heat energy is stored heat (W) passing through the copper pipe 42 The heat energy of the main body 41 is received to be in a state of being preheated. The code | symbol K shows the soldering part which shows the part which soldered so that the copper pipe 42 wound by the heating main body 41 could not rotate.

In addition, the temperature sensor 46 is provided in the heating body 41 to be in contact with the rod heater 45 as shown in FIG. 10, when the rod heater 45 generates excessive heat, the temperature sensor 46 detects this. The detection signal is applied to the power supply unit control unit 50, and thus the power supply unit control unit 50 blocks the electric energy supplied to the rod heater 45.

The rod heater 45 is already known as the outer shell is made of a metal body and the heater coil is built therein, so detailed drawings and description thereof will be omitted.

Therefore, the rod heater 45 is always heated to a constant temperature to generate a constant heat energy, but the heating body 41 made of a metal body such as aluminum is heat storage, so if the operation of the heating body 41 for a long time is more It can be raised and the heat energy of the elevated temperature is transferred to the metal shell of the rod heater 45, the shell temperature of the rod heater 45 is raised.

Therefore, when the temperature of the heating body 41 rises higher than the heating temperature set in advance by the power supply control unit 50, the temperature sensor 46 detects this and applies the power supply control unit 50 to the rod heater. When the power supplied to the (45) is cut off, and the temperature sensor 46 senses a temperature lower than the heating temperature set in advance in the power supply control unit 50 is applied to the power supply control unit 50 The power is supplied again to the rod heater 45 so that the heating body 41 can maintain a constant temperature.

And the present invention is configured to have a bimetal 47 on one side of the heating body 41 as shown in Figure 11 in case the temperature sensor 46 is broken.

That is, when the temperature sensor 46 loses its function, the temperature of the heating body 41 is raised to a high temperature because the power supply unit control unit 50 cannot cut off the power supplied to the rod heater 45.

At this time, the bimetal 47 is operated to cut off the power supplied to the rod heater 45 automatically by receiving the high temperature heat energy of the heating body 41, thereby preventing the heating body 41 temperature from rising to a high temperature. . Since the bimetal 47 to cut off power by receiving heat as described above is already known, detailed drawings and descriptions thereof will be omitted.

1 and 2, a discharge nozzle 48 through which steam S is ejected is provided in front of the steam generating hole 43 of the heating body 41, and the discharge nozzle 48 has a steam hose. 60 is connected to the steam hose 60 is configured to have a steam cleaning device 70 having a handle 71 and the injection nozzle 72.

In some cases, the injection nozzle 72 may be equipped with a nozzle (unsigned) having a sole, as shown in FIG. 1, so that the steam S may be sprayed and cleaned using a brush.

Therefore, the present invention, as shown in Figure 12, when the use time of the steam cleaner is short or can be cleaned with only a relatively small amount of steam, the internal connection hose to use the water (W) of the inner container (2) ( 4) the water supply module 10 is to be connected to be supplied by using, in this case, because the inner bucket (2) is mounted to the case (1) is convenient to move to use as a home steam cleaner It is desirable.

And as shown in FIG. 13, the present invention separates the internal connection hose 4 from the water supply module 10 and connects the external connection hose 5 to the second connection part 12. Can be supplied, so that when the use time of the steam cleaner is long or the amount of water in the inner bucket 2 is insufficient, it is possible to supply the water (W) of the outer bucket 3 having a large capacity. It is convenient to use for special purposes such as when cleaning the air conditioner filter, etc., so the steam cleaner according to the present invention selectively selects the water (W) of the inner bucket (2) or the outer bucket (3) according to the object or purpose of steam cleaning. Since it can be used, it is preferable for multipurpose use.

In addition, the present invention is provided with a steam generating hole 43 in the longitudinal direction in the rod-shaped heating body 41, as shown in Figure 2 and the water (W) by the plunger pump 20 (W) 43) since the steam (S) is generated quickly and the steam blowing pressure is increased.

That is, the present invention is to move the magnetic plunger 25 in the direction of the discharge nozzle member 30 because the magnetic plunger 25 of the plunger pump 20 is reciprocated to transport the water (W) forcibly supplied. Every time it moves, the water W is in a state of being pressurized.

Therefore, whenever the magnetic plunger 25 of the plunger pump 20 moves forward to the discharge nozzle member 30 toward the steam generating hole 43 of the heating main body 41, the water (W) flows into the steam generating hole 43. ) Will flow.

Therefore, a constant amount of water (W) is instantaneously and repeatedly introduced into the steam generating hole (43), and the water (W) thus introduced is one side of the steam generating hole (43) of a slightly longer shape. It flows in the other direction and flows in the other direction, and receives the heat energy of the heating body 41. Of course, the water (W) flowing into the steam generating hole 43 is the water (W) already preheated in the copper pipe 42 is introduced.

Accordingly, the water (W) introduced into the steam generating hole 43 flows from the left to the right in FIG. 2, where a large amount does not flow, but a certain amount of pressure that is momentarily pushed whenever the magnetic plunger 25 reciprocates. Since water (W) flows, the heat energy of the heating main body (41) becomes heat transfer more quickly, and thus changes to steam (S) while flowing to the middle portion of the steam generating hole (43) shown in FIG.

That is, the magnetic plunger 25 is received because the amount of heat energy received in a large amount of water and the amount of heat energy received in a small amount of water are transmitted more quickly and in a condition where the heating temperature and the heating time are the same to help the present invention. Every time the reciprocating motion is instantaneously pumped to a certain amount of water (W) flowing into the steam generating hole 43 is to be quickly converted to steam (S).

The converted steam S receives heat energy of the heating body 41 while staying in the steam generating hole 43 from the middle of the steam generating hole 43 to the boundary with the discharge nozzle 48. Steam (S) temperature is raised.

Therefore, since the steam pressure is increased as the steam temperature is increased by receiving more heat energy in the limited space of the steam S, the heat energy of the heating body 41 is maintained while the steam S stays in the steam generating hole 43. The steam temperature is increased and the steam ejection pressure is increased.

Therefore, the steam S discharged to the discharge nozzle 48 is not only discharged at a high blowing pressure in a state having a higher temperature, but also a discharge nozzle 48 having a narrower steam passage cross-sectional area than the cross-sectional area of the steam generating hole 43. The steam (S) is ejected through) so that the steam ejection speed is also rapidly increased to be ejected, so that it is possible to perform a superior steam cleaning and the steam cleaning efficiency is greatly improved.

And the present invention is to operate the power supply unit control unit 50 to complete the steam (S) cleaning the power supply to the rod heater 45 by the power supply unit control unit 50 command is cut off steam to the steam generating hole 43 (S) As the discharge is completed, only the plunger pump 20 is further operated.

Therefore, when only the plunger pump 20 is operated, the cold water is supplied to the steam generating hole 43, so that the heating body 41 is cooled, and after the cooling operation is performed for an entire time, the plunger pump 20 is operated. Will be stopped.

Therefore, since the steam control means 40, which is in a high temperature state for a while after cleaning with steam S, cools down quickly by cold water, it is not only able to be used in a more secure state, but also of the steam control means 40. By preventing aging in advance, the life of the steam cleaner is increased.

In addition, according to the present invention, when the plunger pump 20 is operated in a state in which the heating temperature of the heating body 41 is at a medium temperature, the water W passing through the steam generating hole 43 does not change into steam S. By receiving only thermal energy it may be in a state of being discharged to the injection nozzle 72 of the steam cleaning tool 70 in the hot water (W) state.

In this case, for example, when cleaning an air conditioner filter that is stuck with steam, the air conditioner filter is immersed in hot water for a while. To facilitate simple and easy cleaning.

On the other hand, since the control circuit of the power supply unit and the control unit 50 to be operated as described above is a known circuit, detailed drawings and descriptions thereof will be omitted.

And the present invention is an alarm sounds and the power lamp (not shown) when the steam control means 40 is raised to a high temperature in the absence of water (W) of the inner bucket (2) or the outer bucket (3) during the steam (S) cleaning ) May have a variety of functions, such as switching off from the lit state to the flashing state (emergency light state), but the power is also cut off, but these functions and control circuits are already known, so detailed drawings and descriptions will be omitted.

Accordingly, the present invention, although illustrated and described by one embodiment, is not limited thereto and may be modified in various forms by those of ordinary skill in the art to which the present invention pertains without departing from the scope of the claims. Unless it is widely protected, it is self-evident.
