Description

Ultrasonic cleaner

The present invention relates to an ultrasonic cleaner, and more particularly, to an ultrasonic cleaner capable of increasing the convenience and efficiency of work because a washing space is separated by baskets in which washings are placed, so that various kinds of washing can be washed at the same time. it's about

In general, washing fruits and vegetables by diluting an appropriate amount of detergent in water or washing with running water is used.

However, when washing fruits and vegetables by diluting the detergent in water, there is a problem in that the detergent remaining on the surface of the fruits and vegetables is consumed.

In addition, if the washing method under running water is used, there is a problem in that pesticides and impurities remain and ingested in fruits and vegetables.

Intakers who consume these fruits and vegetables have a problem of ingesting residual detergents and pesticides.

In order to solve this problem, Korean Patent Registration No. 10-1754056 (title of invention: ultrasonic cleaner with built-in vibrator control amplifier) (hereinafter referred to as 'prior art') was developed.

1 is a perspective view of the prior art.

As shown in FIG. 1 , the prior art 100 includes a water tank 110 , a vibrating means 120 , and an amplifier module 130 .

The water tank 110 is formed with a coupling hole 111 penetrating through one side of the surface, and the vibration means 120 is installed in the coupling hole 111 .

The vibrating means 120 is installed by being inserted into the coupling hole 111 formed in the water tank 110 .

In addition, the vibration means 120 uses a vibrator utilizing a piezoelectric element that generates vibration when a voltage above a specific level is applied, so that the frequency can be controlled by voltage control.

The vibration means 120 transmits vibration to the water tank 110 to generate ultrasonic waves.

The amplifier module 200 is a controller that controls the frequency by adjusting the voltage supplied to the vibration means 120 , and includes an inverter unit (not shown) and a signal conversion unit (not shown).

The inverter unit converts the voltage of the power supplied from the external power source to the vibration means 120 within the rated voltage range.

The signal conversion unit adjusts the voltage of the power converted by the inverter unit to a set voltage.

The amplifier module 200 adjusts the power supplied from the external power source through the inverter unit and the signal conversion unit to a desired voltage and supplies it to the vibration means 120 .

At this time, since the frequency of the vibration means 120 is changed by the voltage supplied from the outside, the frequency is changed according to the voltage adjusted by the amplifier module 200 .

In the prior art 100 configured as described above, since contaminants adhering to the surface of the washing material are removed by vibration, and there is no need to add detergent during the washing process, the time to remove the detergent is not required, so the washing time is reduced.

Also, in the prior art 100 , the intensity of ultrasonic waves generated into the water tank can be adjusted by changing the frequency of the vibration means 120 by adjusting the voltage of the power supplied from the external power source through the amplifier module 200 .

However, in this prior art 100, the washing space consists of a single water tank 110, and since there is no separate means for separation, when washing various types of washings at the same time, the washings are mixed with each other by vibration, so that the washings are washed after washing. A process of separating water is required, which causes a problem in that the washing time is increased.

In addition, in the prior art 100, since the washing process is performed in one water tank 110, in order to add or separate washing material during washing, the washing unit is added or separated while the vibration means 120 is stopped, and then again There is a problem that the cleaning time increases because it has to be carried out.

In addition, in the prior art 100, the amount of washing is limited because washing is contained in one basket, and thus a large amount of washing cannot be washed.

The present invention is to solve this problem, and the problem to be solved is to prevent the washings from mixing with each other when washing different washings by being configured so that washings are separated by baskets installed in the water tank. To provide an ultrasonic cleaner with

Another object of the present invention is to provide an ultrasonic cleaner in which handles are installed in the baskets, and the ends of the handles are formed to protrude to the outside of the water tank, thereby separating or inserting the baskets into which the laundry is inserted during washing. .

In addition, in the present invention, the baskets further include handles, and when the baskets are installed into the water tank, it is preferable that the ends of the handles are located outside the water tank.

In addition, in the present invention, protrusions protruding upward from the upper surface are formed at the ends of the handles of the basket located second from the upper end of the baskets in the present invention, and the protrusions are formed on the handles of the basket located at the top of the baskets. It is preferable that the inserted protrusion insertion holes are respectively formed.

According to the present invention having the above problems and solutions, the washings are separated by the baskets installed in the water tank, and the different types of washings can be washed by being configured so that the water is movable by the grooves formed in the bottom plate of the baskets. In this case, it is possible to reduce the overall washing time by eliminating the process of separating the washings after washing is completed by preventing the washings from mixing with each other.

In addition, another solution to the present invention is that handles are installed in the baskets, and the ends of the handles are formed to protrude to the outside of the water tank, so that the baskets into which the laundry is inserted can be separated or inserted during washing, so that different washing times can be saved. When washing the washing material having a cleaning time, it is possible to reduce the washing time by replacing the washing material having a relatively short washing time.

At this time, although not shown in the drawing, an electric connector electrically connected to the connection part 112 is installed in the insertion groove 122 .

The insertion protrusions 113 are formed to protrude upward from the upper surface of the power supply unit main body 111 to surround the outer peripheral surface of the connection unit 112, and are formed to be spaced apart from each other at regular intervals.

These insertion protrusions 113 are inserted into the insertion groove 122 formed on the lower surface of the water tank 12 when the water tank 12 is seated on the upper part of the power supply unit main body 111 so that the water tank 12 is subjected to external shock and vibration. to prevent it from being moved by

In the present invention configured as described above, when the water tank 12 is seated on the upper portion of the power unit main body 111, the connection unit 112 is electrically connected to the insertion groove 122 to receive power and the insertion protrusion 113. The movement of the water tank 12 is prevented by these.

As shown in FIG. 3 , the water tank 12 is formed in a cylindrical shape with an open top, and the diaphragm 121 is installed at a position spaced upward from the bottom plate.

When the diaphragm 121 receives power from the outside, it vibrates the water contained in the water tank 12, and due to the vibration of the diaphragm 121, contaminants attached to the surface of the washing water contained in the water tank 12 are removed.

In addition, an insertion groove 122 into which the connection part 112 of the power supply unit 11 and the insertion protrusion 113 are inserted is formed on the outer surface of the bottom plate of the water tank 12 . At this time, the insertion groove 122 receives power from the power supply unit 11 when the water tank 12 is seated on the upper part of the power supply unit 11 by installing an electric connector electrically connected to the connection unit 112 .

Also, between the bottom plate of the water tank 12 and the diaphragm 121 , a control unit 123 for operating the diaphragm 121 by power supplied from the insertion groove 122 is installed.

When the water tank 12 is seated on the upper portion of the power supply unit 11 , the connection unit 112 is inserted into the insertion groove 122 to receive power. At this time, the diaphragm 121 is vibrated by the supplied power to vibrate the water in the water tank 12, thereby separating the contaminants attached to the surface of the washing material by vibration.

In addition, since the handle 124 is installed on the upper part of the water tank 12 , the user can move the water tank 12 easily.

Moreover, the 1st basket 13 and the 2nd basket 14 are provided in the inside of the water tank 12. As shown in FIG.

At this time, although it has been described as an example that two baskets 13 and 14 are installed in the water tank 12, the number of baskets is not limited thereto, and one or three or more baskets may be installed.

4 is a perspective view of the first basket and the second basket of FIG. 2 , and FIG. 5 is a cross-sectional view illustrating the ultrasonic cleaner of FIG. 2 .

The first basket 13 is formed in a cylindrical shape with an open top, and a plurality of water-through holes 131 are formed in the bottom plate.

In addition, the first basket 13 is provided with a first handle 132 on the upper end of the outer peripheral surface.

In addition, the first basket 13 is formed to have an outer diameter equal to or smaller than the inner diameter of the water tank 12 .

In addition, the first basket 13 has a height lower than the washing space formed in the water tank 12 .

The first basket 13 is inserted and installed into the water tank 12 , and the first handle 132 is in contact with the upper surface of the water tank 12 , thereby limiting downward movement, and due to the height difference, the bottom plate is the vibration plate of the water tank 12 . It is installed to be spaced apart from (121).

For this reason, when the first basket 13 is installed in the water tank 12 , the washing material is inserted between the bottom plate of the first basket 13 and the diaphragm 121 of the water tank 12 inside the water tank 12 . A first washing space (A1) that can be formed is formed.

The second basket 14 is formed in a cylindrical shape with an open top, and a plurality of water-through holes 141 are formed in the bottom plate.

In addition, the second basket 14 is provided with a second handle 142 at the upper end of the outer peripheral surface.

In addition, the outer diameter of the second basket 14 is smaller than or equal to the inner diameter of the first basket 13 .

In addition, the height of the second basket 14 is formed lower than the height of the first basket 13 .

The second basket 14 is inserted into the interior of the first basket 13 , and the second handle 142 is in contact with the first handle 132 , thereby limiting downward movement. At this time, the second basket 14 is installed such that the bottom plate is spaced apart from the bottom plate of the first basket 13 due to the height difference.

Due to this, a second washing space A2 in which the washing material can be inserted is formed in the water tank 12 between the bottom plate of the second basket 14 and the bottom plate of the first basket 13 .

In addition, a third washing space (A3) into which the washing material can be inserted is formed in the inside of the water tank 12 between the bottom plate of the second basket 14 and the upper surface of the water tank 12 .

In this case, the ultrasonic cleaner 1 has been described as an example that two baskets 13 and 14 are used for convenience of explanation, but the number of baskets is not limited thereto, and one or three or more baskets may be used. have.

In this way, the water tank 12 is configured such that the inner space is separated into the first, second, and third washing spaces (A1), (A2), (A3) by the baskets (13) and (14). At this time, since water-through holes 131 and 141 are formed in the bottom plate of the first basket 13 and the second basket 14, respectively, water can be moved inside the water tank 12, but movement of the laundry is limited. .

For this reason, even if washing proceeds in a state in which different washings are accommodated in the first washing space A1, the second washing space A2, and the third washing space A3 inside the water tank 12, mixing can be prevented.

In addition, when the size of the washing water inserted into the first washing space A1 is larger than the first washing space A1, the water tank 12 separates the first washing space A1 from the second washing space A2. When the first basket 13 is removed, the first washing space A1 and the second washing space A2 are combined to accommodate a larger amount of laundry.

In the ultrasonic cleaner 1 configured as described above, the movement is not limited because the water tank 12 is connected to the external power source and the power supply unit 11 . Water, washing, etc. may be inserted into the water tank 12 in a state in which it is separated from the power supply unit 11 through 124 .

In addition, in the ultrasonic cleaner 1, since the washing spaces (A1), (A2), (A3) are separated by the baskets (13) and (14), the operator can adjust the size and type of the washing material to the basket (13), ( 14) is inserted or separated, the washing spaces (A1), (A2), (A3) formed in the water tank 12 can be arbitrarily separated or merged.

At this time, the cross-sectional area of the internal space of the water tank 22 is formed to be larger than the lower part at the upper part with the first step 225 as a boundary.

In addition, the second step 226 is formed on the inner wall at a position upwardly spaced apart from the first step 225 in the height direction.

At this time, the cross-sectional area of the water tank 22 is formed to be larger at the upper part than the lower part by the second step 226 as a boundary.

The inner space of the water tank 22 is divided into three spaces having different cross-sectional areas by the steps 225 and 226 as a boundary.

At this time, for convenience of explanation, as shown in FIG. 6 , the inner space of the water tank 12 is a space between the diaphragm 121 and the first stepped 125 , the first space B1 and the first stepped 125 . The space between the and the second step 126 will be described as a second space B2, and the space between the second step 126 and the upper surface of the water tank 12 will be described as a third space B3, for example.

The first space B1, the second space B2, and the third space B3 are spaces into which the laundry is inserted.

At this time, the third basket 23 is installed in the second space B2 , and the fourth basket 24 is installed in the third space B3 .

Figure 7 is a perspective view of the third basket and the fourth basket of Figure 6;

As shown in FIG. 7 , the third basket 23 and the fourth basket 24 are formed in a cylindrical shape with an open top, and a plurality of water-through holes 231 and 241 are formed in the bottom plate, respectively. .

At this time, the cross-sectional area of the 3rd basket 23 is smaller than the cross-sectional area of the 3rd space B3 and the 2nd space B2, and is larger than the cross-sectional area of the 1st space B1.

Due to this, when the third basket 23 is inserted into the water tank 22 , the lower surface is in contact with the first step 225 , thereby limiting the downward movement.

In addition, the cross-sectional area of the fourth basket 24 is smaller than the cross-sectional area of the third space B3, and since it is larger than the second space B2 and the first space B1, when inserted into the water tank 22, the lower surface is Downward movement is limited by being in contact with the second step 225 .

In addition, in the water tank 22, the first space (B1) and the second space (B2) are separated by the bottom plate of the third basket (23), and the second space (B2) and the third space (B3) are the fourth space. It is separated by the bottom plate of the basket (24). At this time, since water-through holes 231 and 241 are formed in the bottom plate of the third basket 23 and the fourth basket 24, respectively, water can be moved inside the water tank 22, but movement of the laundry is limited. .

For this reason, mixing of the washings is prevented even when washing is performed in a state in which different washings are accommodated in the first space (B1), the second space (B2), and the third space (B3) inside the water tank 22 be able to do

In addition, when the size of the washing water inserted into the first space (B1) is larger than the first space (B1) in the water tank 22, when the third basket 23 is removed, the first space (B1) and the second space ( Since the bottom plate of the third basket 23 that separates B2) is removed, it is also possible to wash laundry having a size equal to the space in which the first space B1 and the second space B2 are combined.

The ultrasonic cleaner 2 configured in this way is configured such that the baskets 23 and 24 are seated inside the water tank 22 by the steps 225 and 226 formed on the inner wall of the water tank 22, so that the third When the basket 23 and the fourth basket 24 are inserted into the water tank 22, the downward movement of the baskets 23 and 24 is restricted.

When the third basket 33 is installed in the water tank 32, the first basket handle 332 is configured to protrude to the outside of the water tank 32. It is possible to separate the water from the water tank 32 without putting the water in the hands.

In addition, when the third basket 33 is installed in the water tank 32 , the third basket handle 332 is inserted into the handle insertion groove 37 formed in the water tank 32 , and the fourth basket 34 and the third basket The handle 332 is contacted to prevent movement of the fourth basket 34 from being restricted.

The fourth basket handle 342 is connected to the outside from the outer wall of the fourth basket 34, and a protrusion insertion hole 3421 into which the protrusion 3323 of the third basket handle 332 is inserted is formed.

In addition, the fourth basket handle 342 is formed to be longer than the length of the holder 3322 of the third basket handle 332 .

When the fourth basket handle 342 is installed, the protrusion 3323 formed in the third basket handle 332 is inserted into the protrusion insertion hole 3421 .

Also, since the ultrasonic cleaner 3 is formed to have a longer length than the length of the holder 3322 of the third basket handle 332, as shown in FIG. 9, when the ultrasonic cleaner 3 is installed, the fourth basket handle An end of the 342 is positioned outside the end of the third basket handle 332 .

When the ultrasonic cleaner 3 presses the outer end of the fourth basket handle 342 upward in a state in which the upper end of the protrusion 3323 is pressed downward, the third basket 33 is located in the water tank 32 . In this state, only the fourth basket 34 can be separated from the water tank 32 .

In addition, when the ultrasonic cleaner 3 presses the holder 3323 of the third basket handle 332 upward, the third basket 33 and the fourth basket 34 are coupled by the protrusion 3323 . Therefore, the third basket 33 and the fourth basket 34 can be simultaneously separated from the water tank 32 .

In the ultrasonic cleaner 3 configured in this way, since the basket handles 332 and 342 protrude from the water tank 32 to the outside, the baskets 33, 34 ) can be arbitrarily separated.

For this reason, the ultrasonic cleaner 3 inserts the washing material that requires a long washing time into the space formed between the third basket 33 and the diaphragm 321, and puts it into the third basket 33 and the fourth basket 34. If the washing is performed by inserting the washing material that requires a relatively short washing time, it can be washed by replacing the washing material in the baskets (33) and (34) while the washing material requiring a long washing time is being washed. Therefore, it is possible to wash more types of laundry in the same time.

In addition, since the ultrasonic cleaner 3 can separate the baskets 33 and 34 through the basket handles 332 and 342, the washing is completed and the basket 33 is not soaked in water containing contaminants. ) and (34) can be separated.
