Description

Technical field

The present invention relates to a combination washing machine, and more particularly, to a combination washing machine including an auxiliary washing machine that is capable of being used as a stand for a main laundry treating machine, such as a washing machine or dryer, and to perform a washing operation.

Disclosure Prerequisites

Typically, laundry machines are household appliances that are capable of washing and / or drying laundry. Specifically, each laundry machine performs a washing operation, a drying operation, or a washing and drying operation. Recently, a laundry machine containing a steam generator that is capable of performing a recovery operation to remove wrinkles, odors and static electricity from the laundry is being used more and more.

Based on the direction in which the laundry is removed, known washing machines can be divided into a front loading laundry machine and a top loading laundry machine. Based on the method of washing clothes, on the other hand, known washing machines can be divided into a machine for processing laundry with a vertical shaft in which the pulsator or the inner tank rotates, and a horizontal machine in which the horizontally located drum rotates. An illustrative example of a horizontal laundry machine is a drum type washing machine or a drum type drying machine.

The size of laundry machines is gradually increasing to meet the requirements of consumers. Specifically, the outer dimensions of laundry machines for home use are gradually increasing.

Typically, a large volume washing machine is installed in every home. Therefore, when the user sorts the laundry by type and separately erases the sorted laundry items, it is necessary for the user to turn on the washing machine several times. For example, when a user wants to wash separately one type of laundry, such as adult clothes, and another type of laundry, such as underwear or children's clothes, the washing machine is turned on for washing clothes for adults, and after washing the clothes for adults, the washing machine is turned on again for washing underwear or children's clothing. As a result, the washing time is increased, and in addition, the energy consumption is increased.

In addition, the use of the known large-sized washing machine for washing relatively small amounts of laundry is not preferable in terms of energy saving. The washing mode of a large washing machine is usually set based on a large amount of laundry, resulting in a large amount of water being consumed. In addition, it is necessary to rotate the drum or the inner tank of a large size, as a result of which the energy consumption is significant. In addition, the washing mode is set based on a large amount of laundry, as a result of which the washing time is relatively long.

On the other hand, the washing mode of the large washing machine is usually set for ordinary clothes. As a result, the washing mode of the large washing machine is not suitable for washing thin clothes such as underwear or baby clothes.

In addition, the large washing machine is not suitable for frequent washing of small amounts of laundry. Typically, consumers collect laundry for several days or more to wash all the laundry at the same time.

However, it is impractical to leave underwear or baby clothes washed for a long time. When the laundry is left washed for a long time, dirt adheres to the laundry, making it difficult to wash the laundry.

For this reason, there is a need for a small-sized washing machine to have a volume much smaller than a large-sized washing machine.

However, installing two washing machines side by side in the same house is not preferable, even if the size of the washing machines is small, taking into account the use of space or design.

1 is a perspective view illustrating a known laundry machine.

As shown in FIG. 1, a known laundry treating machine 1 includes a main body 10 defining an appearance of a laundry treating machine and a control panel mounted in front or on top of the main body 10. The control panel may include a control device for controlling the operation of the machine for processing linen. Therefore, it is possible for the user to control the control panel so that the laundry machine performs a washing operation or a drying operation.

The laundry machine may be a washing machine, a dryer, or a washing and drying machine.

On the other hand, a known laundry machine may further include a stand 20 for supporting the main body 10 on the floor. The main body 10 is mounted on a stand 20.

However, the stand is only used to support a known washing machine or known drying machine, but is not used for other purposes.

The best embodiment of the invention

Reference will be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

As shown in FIGS. 2 and 3, the auxiliary washing machine 100 in accordance with the present invention comprises a cabinet 110 defining the appearance of the auxiliary washing machine.

The cabinet 110 comprises a cabinet body 130 and a drawer 120. The drawer 120 has a structure according to which the drawer 120 can be pulled outward from the front side of the cabinet 120 and inserted back into the cabinet 120.

The cabinet 130 of the cabinet has a size suitable for the known washing machine mounted on it. In addition, the housing 130 of the cabinet has structural strength. An outer tank 140 is fixedly mounted in the drawer 120.

On the drawer 120, there is an upper frame 121 for closing the upper part of the drawer 120. The outer tank 140 is integrally formed with the upper frame 121.

At the top opening of the outer tank 140, a tank door 141 is installed. A frame 142 is formed on the inner wall of the outer tank 140, such that the door frame 142 protrudes in a circumferential direction. An element 144 for sealing the door is mounted on the tank door 141. Therefore, when the tank door 141 is closed, the door sealing member 144 comes into contact with the door frame 142 to seal the top of the outer tank 140.

In addition, a hook 143 is formed on the tank door 141. A hook 143 is inserted into a hook groove (not shown) formed on the inner wall of the outer tank 140. The hook 143 is supported by a spring (not shown) installed in the hook groove. The end of the hook 143 is rounded, and therefore, when a corresponding force is applied to the door 141 to open or close the door 141, the hook 143 is easily detached from or inserted into the hook groove.

The hook may take the forms commonly used in other known hooks. Instead of a hook, another possible locking device may be used.

The auxiliary washing machine 100 has a relatively small height, as a result of which washing water can spill out of the outer tub 140. However, splashing of the washing water is prevented by installing the tub door 141.

In the outer tank 140, an inner tank 150 is installed. The inner tank 150 is provided with a plurality of through holes through which washing water enters and exits. In another embodiment, the inner tank 150 may be a pulsator.

The outer tank 140 has an opening in the center of its bottom plate. A bearing housing 192 is mounted in the hole. A flexible sealing element is mounted between the bearing housing 192 and the bottom plate of the outer tank 140, i.e. gasket 122.

In the bearing housing 192, the stator of the electric motor 190 is fixedly mounted. The electric motor 190 is an electric motor with an external rotor. The rotating motor shaft 191 is supported by a bearing housing 192. The rotary shaft 191 of the electric motor is directly connected to the lower part of the inner tank 150.

In addition, the electric motor 190 has a compact design. The diameter of the electric motor 190 is greater than the height of the electric motor 190.

Shock absorbers 160 and 162 are connected to bearing housing 192 to support bearing housing 192.

A drain pipe 170 is connected to the bottom of the outer tank 140 to drain the water. One end of the drain pipe 170 is attached to the cabinet body 130, so that one end of the drain pipe 170 is connected to the outside, and the other end of the drain pipe 170 is connected to the lower part of the outer tank 140. A drain pump 172 is connected to the drain pipe 170.

Part of the drain pipe 170 is made of a bellows pipe 171, which can be stretched and compressed in its longitudinal direction. Therefore, when the drawer 120 extends outward, the bellows pipe 171 is stretched.

Instead of a bellows pipe, a telescopic design can be used.

One end of the water supply pipe 180 is connected to the top of the outer tank 140. The other end of the water supply pipe 180 is connected to a water supply valve 182. The water supply pipe 180 also includes a bellows pipe 181.

In addition, a steam generator 185 is installed to supply steam to the external tank 140. The steam generator 185 has a structure in which a water supply pipe 186 of the steam generator 185 is connected to a water supply valve 182 so that water is supplied to the steam generator 185. The steam is supplied to the external tank 140 through steam supply pipe 187.

The steam supply pipe 187 for supplying steam has a variable length design, such as a bellows pipe.

The steam supply pipe 187 has a steam outlet that is located above the inner tank 150, so that steam can be supplied to the inner tank 150.

The steam generator may be of the same construction as the steam generator used in a known washing machine.

Preferably, the steam generator is located in the upper corner of the stand 110.

4 illustrates an electric motor with an internal rotor. The rotating shaft 191 of the electric motor is connected to the inner tank 150. An bracket 193 is mounted on the outer circumference of the electric motor. Shock absorbers 160 and 162 are connected to the bracket 193.

A front panel 123 of the control panel 123 is installed.

Below, with reference to FIG. 5, a control block diagram of an auxiliary washing machine in accordance with the present invention will be described.

The auxiliary washing machine in accordance with the present invention includes a control panel 123 that is independent of the main washing machine. The control panel 123 is preferably mounted in front of the drawer 120. The control panel 123 is configured to control and control only the auxiliary washing machine 100, regardless of the main washing machine.

The control panel 123 includes various buttons and a handle as the main input device 30 for the user to enter a washing command such as a washing mode. The control panel 123 also includes a window on a liquid crystal display (LCD) screen and an LED lamp as a display device 60 for displaying washing information. In addition, the control panel 123 includes an audio output device 70 for generating an alarm or a speech signal, if necessary, depending on the operating state of the auxiliary washing machine 100.

In addition, the control panel 123 includes a control device 80 for controlling the load 50 for washing, such as an electric motor 190, a steam generator 185, a water supply valve 182, and a sump pump 172 configured to control the auxiliary washing machine 100.

The control panel 123 further includes a detector 40 for determining a washing mode and an operating condition related to the washing operation of the auxiliary washing machine 100. The signal registered by the detector 40 is transmitted to the control device 80.

The detector includes various sensors necessary for control, such as a water level sensor for measuring a washing water level in an external tank 140, a water temperature sensor for measuring a washing water temperature in an external tank 140, a speed sensor for measuring a rotation speed of an electric motor 190 and a door opener for detecting opening and closing of a door 141.

Therefore, when a signal output from the main input device 30 or the detector 40 is transmitted to the control device 80, the control device 80 controls the operation of the washing load 50, the display device 60, and the audio output device 70.

In addition, a locking device (not shown) may be further included to hold the drawer 120 inserted into the cabinet 130. Preferably, the locking device is an electronic locking device that can be controlled by the control device 80.

Therefore, the control device 80 controls the locking device so that the drawer 120 cannot be pulled out of the cabinet 130 when the inner tank 150 rotates during washing. If the drawer 120 is pulled out while rotating the inner tank 150, strong vibration may occur. Therefore, the control device 80 controls the locking device by determining the rotation state of the inner tank 150. The electronic locking device may be selected from electronic locking devices used in known electronic household devices.

The state of rotation of the inner tank 150 can be determined by the state of rotation of the electric motor 190.

The user may want to extend the drawer 120 during washing. Then, the control device 80 preferably stops the operation of the inner tank, and then releases the locking device. In this case, the control device 80 can control the display device 60 to display the point in time when the drawer 120 can be pulled out after the operation of the inner tank 150 is stopped.

The control panel 123 may include a mode button for determining whether the drawer 120 can be pulled out. Alternatively, it can be determined when the drawer 120 can be pulled out using a sensor, such as a force sensor. For example, when a user applies forces to extend the drawer 120, the force is measured by a force sensor, and the control device 80 compares the measured force with a reference value. When the measured force exceeds the reference value, the control device 80 determines that the user wants to extend the drawer 120.

The force sensor can be installed in the locking groove, in which the locking device formed on the cabinet body is engaged. Therefore, when the user pulls the drawer 120 to extend the drawer 120 from the cabinet body, a force is applied to the force sensor installed in the locking groove, and a signal measured by the force sensor is transmitted to the control device 80.

Below, a method of using the auxiliary washing machine 100 shown in FIG. 3 will be described with reference to FIG. 6.

First, the user pulls out the drawer 120 while holding the grip 124, opens the tub door 141, and loads the laundry into the drawer 120.

After loading the laundry into the drawer 120, the user inserts the drawer 120 into the cabinet 130 and selects a washing related option, such as the washing mode, on the control panel 123 (S10).

When the user presses the start button to control the start of the washing operation, the control device 80 controls the respective elements to execute the washing mode in accordance with the steps of FIG. 5.

First, the control device 80 opens the water supply valve 182 for supplying washing water (S11).

After the water supply is completed, the control device 80 controls the electric motor 190 to rotate the inner tank 150, so that washing is performed (S12).

After washing, the water is rinsed again to rinse the laundry (S13).

At the same time, the control device 80 determines that a washing mode is selected in which the drying step during fast rotation is excluded (S30). When a washing mode is selected in which the drying step during rapid rotation is excluded, the washing mode ends after the rinsing step is completed. On the other hand, when a washing mode is selected in which the drying step during rapid rotation is not excluded, the inner tub 150 rotates at high speed after completing the rinsing step to perform drying (S14) during rapid rotation, and then the washing mode is completed.

The auxiliary washing machine 100 in accordance with this embodiment can be used to wash toys in addition to laundry. In this case, the drying step during rapid rotation can be omitted.

To this end, the main input device 30 of the control panel 123 may include a device for the user to select a washing mode that excludes the drying step during rapid rotation. For example, a washing mode including a drying step in a fast rotation may be selected, or a washing mode excluding a drying step in a fast rotation may be selected. 6 shows that the control panel 123 includes a button for excluding a drying step during rapid rotation. Therefore, when the user selects the washing mode and presses the button for excluding the drying step during rapid rotation, the drying step during rapid rotation is excluded from the washing mode.

In addition, the washing mode may include the step of supplying steam.

A device for activating the steam supply step in the washing mode may be included in the control panel 123. For example, the control panel 123 may include a steam supply button. In this case, when the user selects the washing mode and presses the steam supply button, as shown in FIG. 6, the steam supply step is included in the washing mode (S20).

The steam supply step may be performed to soak the laundry before the start of the washing step. Alternatively, the steam supplying step may be performed during the washing step to enhance the washing effect.

The steam supply step can be used to sterilize the laundry. Moreover, a predetermined quantity of steam is supplied and held for a predetermined period of time, so that a sterilization effect is achieved.

Preferably, steam sterilization is performed after completing the rinsing step or after completing the drying step with rapid rotation.

A device for the user to select a time point for steam supply may be included in the control panel 123. For example, the steam supply button can be made in the form of a round handle, so that the options, for example, before washing, during washing and after washing can be further selected by turning the handle. The control device 80 determines the point in time when steam should be supplied depending on the user's choice (S21).

In the washing step, the rotation direction of the inner tub 150 changes so that the laundry is turned over.

Alternatively, the inner tub 150 rotates, so that the wash water forms V in the washing step. In this case, the inner tank 150 rotates at a higher speed than in the previously considered example.

Alternatively, the washing step may be performed such that centrifugal washing is possible. In this case, the inner tank 150 rotates at a higher speed. The washing water in the inner tub 150 passes through the laundry by centrifugal force and exits the inner tub 150 through the through holes of the inner tub 150.

7-9 illustrate an auxiliary washing machine in accordance with another embodiment of the present invention.

Elements of the auxiliary washing machine in accordance with this embodiment, which are identical to those of the auxiliary washing machine in accordance with the previous embodiment, will be denoted by the same reference numerals, and their description will be omitted.

As shown in FIGS. 7 and 8, the outer tank 140 is mounted in the drawer 120 with the possibility of fixing. At least one support device can be used to support the outer tank 140, connected at one end to the top or bottom of the drawer and the other end to the outer tank 140. FIG. 8 shows an embodiment of the invention when there are four support devices — the first a support device 200, a second support device 202, a third support device 201 and a fourth support device 203 located at the four corners of the cabinet 110.

The supporting devices may be of the same construction as the supporting device for supporting the outer tub 140 in a known washing machine with a vertical shaft.

In Fig. 8, one end of each support device is connected to a corresponding angle of the upper frame 121 covering the upper part of the drawer 120. Alternatively, one end of the support devices can be connected to the corresponding lower corner of the drawer. The other end of each support device is connected to the side wall of the outer tank 140.

The upper part of the outer tank 140 is connected to the upper frame 121 through a flexible sealing element, i.e. the gasket 125. The upper frame 121 and the gasket 125 prevent the penetration of foreign matter, including water, through the gap formed between the outer tank 140 and the drawer 120.

The gasket 125 is flexible, and therefore, the vibration generated by the outer tank 140 is not transmitted to the upper frame 121.

A tank door 141 is mounted on the upper opening of the outer tank 140. The door frame 142 is formed on the inner wall of the outer tank 140, so that the door frame 142 projects in a circumferential direction. Door seal member 144 is mounted on tank door 141. Therefore, when the tank door 141 is closed, the door sealing member 144 comes into contact with the door frame 142 to seal the top of the outer tank 140.

The auxiliary washing machine 100 has a relatively small height, as a result of which washing water can spill out of the outer tub 140. However, splashing of the washing water is prevented by installing the tub door 141.

A pulsator is mounted in the outer tank 140, as shown in FIG. The pulsator is mounted with the possibility of oscillation.

As shown in FIG. 9, the outer tank 140 includes a concave guide 145. The pulsator shaft 156 is connected to the pulsator using a bearing. The end of the pulsator 156 is inserted into the groove 196 formed in the protruding portion 195, which is located on the rotating shaft 191 of the electric motor 190. The groove 196 is located at a predetermined distance from the center of the protruding part 195, so that the groove 196 is eccentric.

Therefore, when the electric motor 190 rotates, the pulsator 155 oscillates in the range of angle 9, while the end of the pulsator 155 is in contact with the guide 145.

The electric motor 190 is fixedly mounted on the outer lower part of the outer tank 140. The electric motor 190 is an electric motor with an external rotor. The stator of the electric motor 190 is fixedly mounted on the outer lower part of the outer tank 140. The rotor rotor shaft 191 is directly connected to the lower part of the pulsator 155 through the lower part of the outer tank 140.

A bearing is mounted on the bottom of the tank 140 to support the rotating shaft 191.

In addition, the electric motor 190 has a compact design. The diameter of the electric motor 190 is greater than the height of the electric motor 190.

The steam generator may be of the same construction as the steam generator used in a known washing machine.
