4 is a block diagram showing the configuration of a system for controlling the water level inside the steam generator in the dishwasher according to the spirit of the present invention.

Referring to FIG. 4, the dishwasher 10 according to the present invention includes a control unit 300 and a water level sensor 130 connected to the control unit 300 and detecting a level of the washing water stored in the steam chamber 101. ), A driving unit 310 whose operation is adjusted according to the level detected by the water level detection sensor 130, a water supply valve 160 connected to the control unit 300, and controlling the supply of washing water, and the control unit 300. A drain valve 150 is included to allow the remaining washing water in the steam chamber 101 to drain.

In detail, the water level sensor 130 includes a first sensor 131, a second sensor 132, and a third sensor 133 as mentioned above. In addition, the driving unit 310 is connected to the control unit 300, the drive is controlled by the control unit 300. More specifically, the driving unit 310 is driven by a heater 120 for heating the washing water in the steam chamber 101, and a washing motor 320 for pumping the washing water stored in the sump 200 to the injection nozzle.

By the above configuration, when the water supply valve 160 is opened and the washing water is supplied, the washing water is stored in the steam chamber 101. In addition, the level of the washing water stored in the steam chamber 101 is controlled by the water level sensor 130. The control unit 300 controls the operation of the heater 120 and the water supply valve 160 according to the washing water level in the steam chamber 101. Then, when the steam supply process is completed, the washing water introduced into the steam chamber 101 flows to the sump 200. Then, when the wash water flows into the sump 200 by the set quantity, the supply of the wash water is stopped. Then, the washing motor 320 is operated to pump the washing water.

5 is a flowchart illustrating a process of adjusting the level of water inside the steam chamber of the dishwasher according to the spirit of the present invention.

Referring to FIG. 5, the water level detection sensor 130 is used in order to maintain the constant water level in the steam chamber 101 of the dishwasher 10 according to the present invention.

In detail, when the operation button of the dishwasher 10 is pressed (S110). Then, the washing water is supplied from the water supply source and stored in the steam chamber 101 in the air brake 100. In addition, in the process of washing water being stored in the steam chamber 101, the controller 300 determines whether the first sensor 131 of the water level sensor 130 is ON (S111). If it is determined that the first sensor 131 is turned on, the heater 120 is driven (S112). Here, the driving time of the heater 120 may be set to the instant when the first sensor 131 is turned on. Alternatively, the driving time of the heater 120 may be driven when the second sensor 132 and / or the third sensor 133 are turned on. It should be noted that various methods can be suggested, such as.

On the other hand, if the wash water is continuously introduced into the steam chamber 101, the control unit 300 determines whether the second sensor 132 and the third sensor 133 is turned on (S113). When the second sensor 132 and the third sensor 133 are turned on, the water supply valve 160 is closed (S114) so that the supply of the washing water is stopped. When a predetermined time elapses, steam is generated in the steam chamber 101, and the generated steam is supplied into the tub 11 through the steam discharge passage 101a. At the same time, the water level inside the steam chamber 101 is gradually reduced.

In detail, the water level sensor 130 determines whether the second sensor 132 is turned off in the steam supply process (S116). If it is determined that the second sensor 132 is off, it is determined whether the first sensor 131 is off (S117). In more detail, when it is determined that the first sensor 131 is turned off, driving of the heater is stopped (S118) and the water supply valve 160 is opened (S119). In addition, when the first sensor 131 maintains the on state, only the water supply valve 160 is opened (S119).

In addition, it is determined whether a predetermined time has elapsed in a state where the water supply valve 160 is opened (S120). Here, the predetermined time may be calculated from the moment when the water supply valve 160 is first opened, or may be calculated from the time when the driving of the heater 120 starts. This is to set a predetermined time for steam supply so that a sufficient amount of steam is supplied into the tub. Therefore, the set time may be appropriately set at the time of product shipment or by a user's input.

In detail, when a predetermined time has not elapsed while the water supply valve 160 is open, a process of determining whether the second sensor 132 and the third sensor 133 are turned on is repeatedly performed. This causes the level of the washing water stored in the steam chamber 101 to be constantly maintained between the second sensor 132 and the third sensor 133 so that the heater 120 in the steam chamber 101 is overheated. This is to prevent.

On the other hand, if it is determined that the predetermined time has elapsed, the driving of the heater 120 is stopped (S121). Then, the drain valve 150 is opened (S122) and the washing water stored in the steam chamber 101 flows into the sump 200. In addition, since the water supply valve 160 is kept open, the washing water supplied through the water supply flow passage 103 is directly supplied to the sump 200 through the sump connection flow passage 107.

Here, determining whether or not the set time has elapsed is performed to determine a time point at which the driving of the heater is stopped and the steam supply stroke ends. In detail, the controller 300 continuously detects whether a predetermined time for supplying steam has elapsed from a time point at which time measurement starts. Therefore, the steam supply stroke may be terminated by reaching the set time during the steam supply process, or the steam supply stroke may be terminated while the washing water is supplied into the steam chamber 101.

More specifically, in addition to allowing the steam supply stroke to be stopped depending on whether or not the set time has elapsed, as another possible embodiment, the first sensor 131, the second sensor 132, and the third sensor 133 are provided. May be determined to determine whether to stop the steam supply stroke. For example, the washing water flow rate may be determined according to the difference between the water level at the moment when the third sensor 133 is turned on and the water level at the moment when the second sensor is turned on. Then, by measuring the number of times the second sensor 132 or the third sensor 133 is turned on or off, the flow rate of the wash water converted to steam will be calculated. Thus, the amount of steam required may be determined according to the capacity of the tub or the amount of dishes, and the number of on / off times of the sensor may be determined according to the determined amount of steam.

On the other hand, the drain valve 150 is opened to start the washing water is supplied to the sump 200, it is determined whether or not the water level inside the sump reaches the set level (S123). Here, the water level inside the sump 200 is detected by the plotter 110.

In addition, when the water level inside the sump 200 reaches the set level, the water supply valve 160 is closed (S124), and at the same time, a next stroke such as pre-cleaning or main washing is performed (S125).

By the above control method, when the steam supply stroke for supplying steam into the dishwasher is performed, the phenomenon in which the heater in the steam chamber 101 is overheated due to lack of washing water is prevented.

By the dishwasher and the control method according to the present invention having the configuration as described above, the water level inside the steam generator is always kept constant while the heater for steam generation is driven, thereby preventing overheating of the heater. At the same time, the fire risk of the dishwasher is prevented.

In addition, since the water level inside the steam generator is kept constant at all times, the on / off cycle of the heater becomes long in the steam generation process, thereby minimizing power consumption.

In addition, since the steam generating stroke is ended and the washing water remaining in the steam generating device is directly introduced into the sump, the water supply time of the washing water is shortened by being used in the next stroke. In addition, since the washing water heated to a high temperature flows into the sump, there is an additional effect of shortening the washing water heating time when the next stroke is a high temperature washing process.
