DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher for washing dishes by injecting washing water into dishes stored in a washing tank.

[0002]

2. Description of the Related Art In recent years, while a cleaning pump is operating in a cleaning process or a rinsing process, a program sequence is interrupted by, for example, temporarily stopping, a door is opened and closed, and tableware is added to a cleaning tank. There has been proposed a dishwasher in which the washing pump is operated intermittently when the program sequence is restarted, and after the cold outside air flowing into the washing tank when the door is opened is gradually warmed, the program sequence is restarted.

Conventionally, a dishwasher of this type has been configured as shown in FIG. Hereinafter, the configuration will be described.

[0004] As shown in the figure, a washing tank 1 stores tableware 2 therein and stores washing water at the bottom. Cleaning nozzle 3
Is rotatably supported in the washing tank 1 and jets washing water toward the tableware 2. The cleaning pump 4 sends cleaning water to the cleaning nozzle 3, and the cleaning pump 4
Driven by The water level sensor 6 detects the water level in the cleaning tank 1 and outputs it as an electric signal. The heater 7 is provided at the bottom of the cleaning tank 1 and heats cleaning water. The thermistor (water temperature detecting means) 8 is attached to the bottom of the cleaning tank 1 so as to be in close contact with the outside, and detects the temperature of the cleaning water. The blower fan 9 sends out steam in the washing tank 1 and is discharged from the exhaust port 10 to the outside of the machine. The tableware basket 11 arranges the tableware 2. The water supply valve 12 supplies tap water into the cleaning tank 1, and the drain pump 13 drains the cleaning water in the cleaning tank 1 out of the machine. The door 14 holds the tableware 2 in the washing tank 1
It is provided to be able to open and close freely to put in and out. The control means 15 controls a series of program sequences of the washing, rinsing and drying steps of the dishes 2.

The operation of the above arrangement will be described. When the user places the dishes 2 in the dish basket 11 and stores it in the washing tank 1 and starts the operation after putting the detergent therein, first, the water level is set at the bottom of the washing tank 1. A predetermined amount of tap water is supplied by the water supply valve 12 until the sensor 6 detects a predetermined water level. Then, the motor 5 and the heater 7 are energized, and the cleaning water is spouted from the cleaning nozzle 3 toward the tableware 2 by the cleaning pump 4 while being heated. At this time, the temperature of the washing water is detected by the thermistor 8, and the control means 15 keeps track of the temperature of the washing water. When the temperature of the cleaning water reaches the predetermined temperature and a predetermined time has elapsed from the start of the cleaning, the control unit 15 ends the cleaning process and drains the cleaning water by the drain pump 13 once.

Next, tap water is newly supplied, and the same operation as in the above-described washing process is performed for several minutes to drain water. After repeating this rinsing step several times, the same operation as the washing step called a heating rinsing step is performed, and when the temperature reaches a predetermined temperature, the operation is finished and drained. Lastly, the blower fan 9 is operated to discharge the steam in the cleaning tank 1 to the outside of the apparatus, and at the same time, the heater 7 is intermittently energized to heat the tableware 2 to dry the attached water droplets.

Here, during the operation of the cleaning pump 13, the program sequence is interrupted by, for example, temporarily stopping, and after opening and closing the door 14, the process of intermittently operating the cleaning pump 4 when resuming the program sequence. Will be described with reference to FIG.

In this type of dishwasher, the door 14 can be opened without pressing the pause button to interrupt the program sequence when the cleaning pump 4 is operating during the cleaning process. At this time, the cleaning pump 4
It stops as if a pause button was pressed, but this is because it is configured to generate an electrical signal of the pause in conjunction with the operation of opening the door 14, and in the following description, The above-described handling of the temporary stop due to the opening of the door 14 is treated as the opening of the door 14 after the temporary stop button is pressed, and the restart of the program sequence due to the closing of the door 14 is similarly performed. Is handled as pressing the restart button after closing the door 14.

If the cleaning pump 4 is temporarily stopped during the cleaning or rinsing process during operation, step 19 in FIG.
In step 20, the number of times the door 14 is opened and closed is initialized, and in step 20, the door 14 is restarted without being opened or closed. Resume.

On the other hand, if it is found in steps 20 and 21 that the door 14 was opened and closed during the temporary stop, the number of opening and closing is added in step 22 and it is found that the door 14 has been restarted in step 23. When it is determined that the door has been opened and closed during the temporary stop, the cleaning pump 4 is intermittently operated in step 25, and then the interrupted sequence is restarted.

As a result, the cold outside air flowing into the cleaning tank 1 when the door 14 is opened is gradually warmed, and then the program sequence is restarted, whereby the above-mentioned cold outside air is rapidly heated and expanded. The blowing of high-temperature steam from the exhaust port 10 can be suppressed.

[0012]

However, in the above-mentioned conventional dishwasher, when the door 14 is opened and closed during the temporary stop in step 24 of FIG. 10, the washing pump is uniquely operated intermittently. For this reason, for example, when the user opens and closes the door 14 to add the tableware 2 to the washing tank 1 shortly after the washing process is started, the water temperature in the washing tank 1 at this time is generally However, since the intermittent operation of the washing pump 4 is performed unconditionally, the time required for the operation to be completed is unnecessarily extended, and a troublesome noise is generated.

The present invention solves the above-mentioned problem, and in the case where the temperature of the cleaning water in the cleaning tank is high when the program sequence is interrupted during the operation of the cleaning pump, the door is opened and closed, and restarted. It is a first object of the present invention to prevent the outside air that has flowed into the cleaning tank when the door is opened from rapidly expanding.

Further, when the program sequence is interrupted during the operation of the cleaning pump, the door is opened and closed for a short time, and small dishes are added to the cleaning tank, that is, the outside air does not flow much into the cleaning tank. In such a case, a second object is to prevent the intermittent operation of the cleaning pump from being restarted.

Further, even when the program sequence is interrupted during the operation of the cleaning pump, the door is opened and closed for a short time and small dishes are added to the cleaning tank, if this is repeated several times, Since the outside air flows into the cleaning tank, the third measure is to prevent the outside air that has flowed into the cleaning tank when the door is opened from suddenly expanding when the door is opened again.
The purpose is.

If the temperature of the cleaning water in the cleaning tank is high when the cleaning pump is in operation, the program sequence is interrupted, the door is opened and closed, and restarted, the cleaning pump flows into the cleaning tank when the door is opened. A fourth object of the present invention is to prevent the flowing outside air from rapidly expanding when the temperature of the outside air is low.

Further, when the cleaning pump is operating, the program sequence is interrupted, the door is opened and closed, and when restarting, the temperature of the cleaning water in the cleaning tank is used to determine the temperature of the outside air flowing into the cleaning tank when the door is opened. A fifth object is to find out what temperature the outside air expands rapidly, and to prevent the outside air from expanding rapidly appropriately according to the temperature of the outside air.

Furthermore, when the dishwasher is installed in a room where the ambient temperature is obviously high, the temperature of the outside air flowing into the washing tank is high even when the door is opened and closed, so that the above-mentioned washing is performed without making various judgments. A sixth object is to prevent the intermittent operation of the pump from being performed.

[0019]

SUMMARY OF THE INVENTION In order to achieve the first object, the present invention provides a washing tank for accommodating dishes, and a door provided to open and close so that the dishes can be taken in and out of the washing tank.

Control means for controlling a series of program sequences of a drying process, wherein the control means interrupts the program sequence during the operation of the cleaning pump, and opens and closes the door before restarting the program sequence; and When the temperature of the washing water exceeds a predetermined temperature, a program sequence is restarted after intermittent operation of the washing pump .
It shall be.

[0020] In order to achieve the second object, the control means interrupts the program sequence during the washing pump operation, opens and closes the door until resuming this,
A second problem-solving means is that the program sequence is restarted without intermittently operating the cleaning pump when the time during which the door is opened is less than a predetermined time set in advance.

In order to achieve the third object, the control means interrupts the program sequence during the operation of the cleaning pump, and opens and closes the door until the program sequence is restarted. The third problem-solving means is that when the number of times of opening / closing exceeds a preset number of times, the program sequence is restarted after the cleaning pump is intermittently operated.

Further, in order to achieve the fourth object,
In addition to the first means , a temperature detecting means for detecting an atmospheric temperature in an installation environment of the dishwasher is provided, and the control means interrupts the program sequence during the operation of the washing pump and sets a door until the program sequence is restarted. Opening and closing, and if the temperature of the cleaning water at this time exceeds a predetermined temperature, and if the ambient temperature at this time is less than the predetermined temperature, the program sequence is performed after the cleaning pump is intermittently operated. The resumption is defined as a fourth problem solving means.

Also, in order to achieve the fifth object,
In addition to the first means , a temperature detecting means for detecting an atmospheric temperature in an installation environment of the dishwasher is provided, and the control means interrupts the program sequence during the operation of the washing pump and sets a door until the program sequence is restarted. And if the ambient temperature at this time is lower than the temperature obtained based on the temperature of the washing water at this time, the program sequence is restarted after intermittent operation of the washing pump.
Means to solve the problem.

Further, in order to achieve the sixth object, in addition to the above-mentioned first means , there is provided an air temperature detecting means for detecting an atmospheric temperature in an installation environment of the dishwasher. The program sequence is interrupted, and the door is opened and closed before the program sequence is restarted.If the ambient temperature at this time exceeds a predetermined temperature, the program sequence is restarted without intermittent operation of the cleaning pump. This is referred to as a sixth problem solving means.

[0025]

First means noted above [action] is washing pump in the cleaning step or rinsing step interrupts the program sequence during operation, performs the opening and closing of the door, the washing water in the washing tank upon re-start The water temperature is detected, and when the water temperature is high, the cleaning pump is intermittently operated to gradually warm the outside air flowing into the cleaning tank when the door is opened, so that it is possible to prevent the outside air from rapidly expanding.

[0026] Then, the second means for solving problems, the washing pump is interrupted program sequence during operation, when the opening and closing of doors, advance measures the time that opened the door, this time is short In other words, if outside air does not flow into the cleaning tank much, the doors must be opened and closed for a short period of time to restart the program sequence without intermittent operation of the cleaning pump following a restart. Is added in the cleaning tank, the program sequence can be restarted without performing useless operation, and it is possible to prevent the time required for terminating the operation from being unnecessarily extended.

According to the third means for solving the problem, when the program sequence is interrupted during the operation of the cleaning pump and the door is opened and closed, the number of times the door is opened and closed is counted. Even when opening and closing and adding small tableware to the washing tank, if this is repeated several times, outside air flows into the washing tank, so when the washing pump is restarted, the washing pump is turned off. The intermittent operation gradually warms the outside air flowing into the cleaning tank when the door is opened, so that it is possible to prevent the outside air from rapidly expanding.

Further, according to the fourth means for solving the problem, the program sequence is interrupted while the cleaning pump is operating, the door is opened and closed, and the temperature of the cleaning water is detected when the cleaning pump is restarted. Detects the ambient temperature in the environment where the dishwasher is installed, and if the ambient temperature is low, the cleaning pump intermittently operates to gradually warm the outside air flowing into the cleaning tank when the door is opened. Inflation can be prevented.

According to the fifth means for solving the problem, the program sequence is interrupted while the cleaning pump is operating, the door is opened and closed, and when the cleaning pump is restarted, the temperature of the cleaning water in the cleaning tank is used to determine when the door is opened. If the temperature of the outside air that has flowed into the cleaning tank is less than or equal to the value, determine whether the outside air expands rapidly.If the temperature of the outside air at this time is lower than this calculated temperature, perform appropriate cleaning. Since the pump intermittently operates to gradually warm the outside air flowing into the cleaning tank when the door is opened, it is possible to prevent the outside air from rapidly expanding.

Further, according to the sixth means for solving the problems, when the dishwasher is installed in a room where the ambient temperature is obviously high, the temperature of the outside air flowing into the washing tank is high even if the door is opened and closed. The program sequence can be restarted without performing the intermittent operation of the cleaning pump accompanying the restart, and the time required until the operation is completed can be prevented from being unnecessarily extended.

[0031]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A reference example according to the present invention will be described with reference to FIG. The same components as those in the above-described conventional example are denoted by the same reference numerals, and description thereof is omitted.

As shown in the figure, the control means 16 controls a series of program sequences of the washing, rinsing and drying steps of the dishes 2 and executes the program sequence during the washing step or the rinsing step while the washing pump 4 is operating. Suspended, door 1
The temperature of the cleaning water in the cleaning tank 1 is detected by a thermistor (water temperature detecting means) 8 when the cleaning tank 4 is opened and closed, and when the water temperature exceeds a predetermined temperature, the cleaning pump 4 is opened. After the intermittent operation, the program sequence is restarted.

The operation of the above configuration will be described with reference to FIG. Note that the control of a series of program sequences of the washing, rinsing, and drying processes of the tableware 2 by the control means 16 is the same as that of the conventional example, so that the description is omitted.
The means for performing the intermittent operation of the cleaning pump 4 with the opening and closing of the door 14 will be described.

When the cleaning pump 4 is temporarily stopped during the cleaning process or the rinsing process, the number of times the door 14 is opened and closed is initialized in step 19 in FIG. If the program is restarted without any error, it is determined in step 24 that the door was not opened or closed during the suspension, and the interrupted program sequence is restarted.

On the other hand, when it is detected in step 20 and step 21 that the door 14 is opened and closed during the temporary stop,
In step 22, the number of times of opening and closing is added. In step 23, it is determined that the door 14 has been opened and closed. Wash water temperature is 40
Temperature (predetermined temperature), and if the water temperature is 40
If the temperature is equal to or higher than the predetermined temperature, the interrupted sequence is restarted after the cleaning pump 4 is intermittently operated in step 25. Resume.

Thus, when the temperature of the washing water in the washing tank 1 is high, the cold outside air flowing into the washing tank 1 when the door is opened is gradually warmed up, and then the program sequence is restarted, whereby the above-mentioned cold sequence is resumed. It is possible to suppress the blowing of high-temperature steam from the exhaust port 10 which is generated by the external air being rapidly heated and expanded.

In the above embodiment, the timing for counting the number of times the door 14 is opened and closed and the temperature for judging the high temperature of the cleaning water in the cleaning tank 1 are specifically shown. The method for performing the intermittent operation is not limited.

Next, a second embodiment of the present invention will be described.

The control means 16 in FIG. 1 interrupts the program sequence while the cleaning pump 4 is operating, and
When the door is opened and closed, the time during which the door 14 is opened is measured. If this time is less than the predetermined time, it is determined that the outside air does not flow much into the cleaning tank 1, and the operation is repeated. The program sequence is restarted without performing the intermittent operation of the cleaning pump 4 at the start. Other configurations are the same as those of the above-mentioned reference example .

The operation of the above configuration will be described with reference to FIG. Steps 19 to 25 in FIG. 3 are the same as those in the above-described reference example, and thus description thereof is omitted.

After adding the number of times the door is opened and closed in step 22, timer measurement for measuring the time during which the door 14 is open is started in step 27, and when it is found in step 28 that the door 14 is closed. In step 29, the timer measurement time t is known. In step 30, only when the time t is within 5 seconds (predetermined time), the door 1
Initialize the number of times of opening and closing of 4.

Thus, when the door 14 is opened and closed for a short time and small dishes are added to the washing tank 1, the program sequence can be restarted without performing useless operation, and the time required for the end of the operation is changed. Can be prevented from stretching.

Next, a third embodiment of the present invention will be described.

The control means 16 in FIG. 1 interrupts the program sequence while the cleaning pump 4 is operating, and
When the door 14 is opened and closed, the number of times that the door 14 is opened and closed is counted. Therefore, even if the door 14 is opened and closed for a short time, the number of times that the door 14 is opened and closed within a predetermined time exceeds a predetermined number of times. In such a case, since outside air flows into the cleaning tank 1, the cleaning pump 4
Is to operate intermittently. The other configuration is the same as the above reference example .

The operation of the above configuration will be described with reference to FIG. Steps 19 to 22 in FIG. 4 are the same as those in the above-described reference example, and thus description thereof is omitted.

After adding the number of times of opening and closing the door in step 22, it is found that the door 14 is closed in step 32.
Until the restart at step 33, the door 14
When the number of times the door is opened and closed is counted and restarted, the program sequence interrupted without intermittently operating the cleaning pump 4 is restarted if the number of times the door is opened and closed is less than three times (predetermined number) in step 34, If the number of times of opening and closing the door 14 is three or more, the cleaning pump 4
After intermittently operating, the interrupted sequence is restarted.

Thus, even when the door 14 is opened and closed a predetermined number of times or more, the cleaning pump 4 is intermittently operated when restarting, so that the cleaning tank 1 is opened when the door is opened.
Since the outside air flowing into the inside is gradually warmed, it is possible to prevent the outside air from rapidly expanding.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The same components as those in the above reference example are denoted by the same reference numerals, and description thereof is omitted.

As shown in the figure, the temperature detecting means 17 detects the atmospheric temperature in the environment where the dishwasher is installed, and the control means 18 controls a series of program sequences of washing, rinsing and drying steps of the dishes 2. Then, the program sequence is interrupted while the cleaning pump 4 is operating, the door 14 is opened and closed, and when the restart, the temperature of the cleaning water is detected by the thermistor 8 and the water temperature is higher than a predetermined temperature. , The ambient temperature in the installation environment of the dishwasher is detected by the air temperature detecting means 17, and when the ambient temperature is lower than a predetermined temperature, the cleaning pump 4 is operated intermittently.

The operation of the above configuration will be described with reference to FIG. Steps 19 to 25 in FIG. 6 are the same as those in the above-described reference example, and thus description thereof is omitted.

When it is determined in step 24 that the door 14 has been opened and closed during the suspension, the temperature of the cleaning water in the cleaning tank 1 detected by the thermistor 8 in step 36 is 40 ° C.
When the temperature is not less than (predetermined temperature) and the ambient temperature detected by the air temperature detecting means 17 in step 37 is not more than 15 degrees (predetermined temperature), the sequence in which the cleaning pump 4 is intermittently operated in step 25 and then interrupted. Resume.

Thus, when the cleaning pump 4 is operating, the program sequence is interrupted, the door 14 is opened and closed, and when the temperature of the cleaning water in the cleaning tank 1 is high when the cleaning pump 4 is restarted, the door 14 is closed. When the temperature of the outside air flowing into the cleaning tank 1 during opening is low, the outside air flowing into the cleaning tank 1 is gradually warmed by appropriately operating the cleaning pump 4 intermittently. Can be prevented from expanding.

Next, a fifth embodiment of the present invention will be described.

The control means 18 in FIG. 5 interrupts the program sequence while the cleaning pump 4 is operating, and
If the temperature of the outside air that flows into the washing tank 1 when the door is opened from the temperature of the washing water in the washing tank 1 when opening and closing is restarted, the outside air expands rapidly. If the outside air temperature at this time is lower than the obtained temperature, the cleaning pump 4 is appropriately operated intermittently. Other configurations are the same as those of the fourth embodiment.

The operation of the above configuration will be described with reference to FIG. Steps 19 to 25 in FIG. 7 are the same as those in the above-described reference example, and thus description thereof is omitted.

When it is determined in step 24 that the door 14 has been opened and closed during the suspension, the temperature of the cleaning water in the cleaning tank 1 is determined to be 70 ° C. or more in step 38, and in step 39, If the temperature of the outside air flowing into the cleaning tank 1 when the door is opened is a value of 25 degrees or less, it is known that this outside air expands rapidly. After the cleaning pump 4 is operated intermittently, the interrupted sequence is restarted.

Similarly, if it is determined in step 40 that the temperature of the washing water in the washing tank is not less than 60 degrees and less than 70 degrees, in step 41 the temperature of the outside air flowing into the washing tank 1 when the door is opened. Is less than 20 degrees, it is known that this outside air expands rapidly, and the temperature of the outside air at this time is 20 degrees.
When the temperature is equal to or less than the degree, after the cleaning pump 4 is intermittently operated in step 25, the interrupted sequence is restarted.

Similarly, if it is determined in step 42 that the temperature of the washing water in the washing tank 1 is not less than 40 degrees and less than 60 degrees, in step 43, the outside air flowing into the washing tank 1 when the door is opened is determined. If the temperature is 15 degrees or less, it is known that the outside air expands rapidly, and the temperature of the outside air at this time is 1
If it is not more than 5 degrees, after the cleaning pump 4 is operated intermittently in step 25, the interrupted sequence is restarted.

By this, if the temperature of the outside air flowing into the washing tank 1 when the door is opened is lower than the temperature of the washing water in the washing tank 1, the outside air is rapidly expanded. The cleaning pump 4 is appropriately operated intermittently according to the temperature of the outside air flowing into the cleaning tank 1 when the door is opened, and the outside air flowing into the cleaning tank 1 when the door is opened is gradually warmed. It is possible to prevent the outside air from expanding rapidly.

Next, a sixth embodiment of the present invention will be described.

When the ambient temperature detected by the air temperature detecting means 17 is clearly higher than a predetermined temperature, the control means 18 in FIG. 5 controls the outside air flowing into the cleaning tank 1 even when the door 14 is opened and closed. Since the temperature is high, when it is determined that the outside air does not expand, the program sequence is restarted without performing the intermittent operation of the cleaning pump 4 accompanying the restart. Other configurations are the same as those of the fourth embodiment.

The operation of the above configuration will be described with reference to FIG. Steps 19 to 25 in FIG. 8 are the same as those in the above-described reference example, and thus description thereof will be omitted.

When it is determined in step 24 that the door 14 has been opened and closed during the temporary stop, if the ambient temperature is equal to or higher than 25 degrees (predetermined temperature) in step 44, the cleaning pump 4 is stopped without intermittent operation. When the ambient temperature is less than 25 degrees, the cleaning pump 4 is intermittently operated in step 25, and then the interrupted sequence is restarted.

Thus, when the dishwasher is installed in a room where the ambient temperature is obviously high, the temperature of the outside air flowing into the washing tank 1 is high even if the door 14 is opened and closed. In addition, the program sequence can be restarted without intermittent operation of the cleaning pump 4 upon restart, and it is possible to prevent the time required until the operation ends from being unnecessarily extended.

[0065]

As is clear from the above embodiments, the present invention
According to the control means , the control unit interrupts the program sequence during the operation of the cleaning pump, opens and closes the door before restarting the program sequence, and when the time during which the door is open is less than a predetermined time, Since the program sequence was restarted without intermittent operation of the cleaning pump, the program sequence was interrupted while the cleaning pump was operating, and when the door was opened and closed, the time during which the door was opened was measured. If this time is short, that is, if the outside air does not flow much into the cleaning tank, the program sequence is restarted without intermittent operation of the cleaning pump following restart, so the door must be opened and closed for a short time. When small tableware is added to the washing tank, the program sequence can be restarted without unnecessary operation, and it is necessary until the operation is completed. While it is possible to prevent the stretch unnecessarily the.

Interrupted the program sequence while the cleaning pump was operating, open and close the door,
When restarting, the temperature of the washing water is detected.If the temperature is high, the ambient temperature of the dishwasher installation environment is detected.If the ambient temperature is low, the cleaning pump is intermittently operated and the door is opened. Since the outside air flowing into the cleaning tank is gradually warmed, it is possible to prevent the outside air from rapidly expanding.

Further, the apparatus is provided with air temperature detecting means for detecting the atmospheric temperature in the environment where the dishwasher is installed. The control means interrupts the program sequence during the operation of the washing pump, and opens and closes the door until the program sequence is restarted. If the ambient temperature at this time is lower than the temperature obtained based on the water temperature of the cleaning water at this time, the program sequence is restarted after intermittent operation of the cleaning pump, so that the cleaning pump is operated during the operation. If the program sequence is interrupted, the door is opened and closed, and restarted, if the temperature of the outside air flowing into the washing tank when the door is opened is less than or equal to the temperature of the washing water in the washing tank, It is determined whether the outside air expands rapidly.If the temperature of the outside air at this time is lower than the obtained temperature, the cleaning pump is appropriately operated intermittently, and when the door is opened, the cleaning pump flows into the cleaning tank.
