TECHNICAL FIELD OF THE INVENTION
The present invention provides a cleaning operation for cleaning an object to be cleaned in a cleaning space with a cleaning liquid, a rinsing operation of rinsing the object to be cleaned with rinsing water stored in a rinsing water storage unit and heated by a heating unit, A drain operation for draining the rinse water stored in the rinse water storage unit, and a drying operation for supplying drying air into the washing space by the ventilation means for drying and discharging gas in the washing space to the outside of the machine. Washing and drying means for controlling the operation of the washing and drying means, wherein the control means performs the washing and drying in the order of the washing operation, the rinsing operation, the drainage operation, and the drying operation. A dishwasher configured to operate the means.
[0002]
[Prior art]
The dishwasher as described above, in the rinsing operation after performing the washing operation, by rinsing the object to be washed with rinsing water heated by the heating means, while making the rinse water easy to evaporate, The drainage operation and the drying operation are sequentially performed, and the object to be cleaned is washed and dried while efficiently drying the object to be cleaned.
[0003]
In this type of dishwasher, the control means includes an operation course for performing all of the cleaning operation, the rinsing operation, the drainage operation, and the drying operation, an operation course for performing only the rinsing operation, or an operation course for performing only the drying operation. The driving course is configured to execute any one of a plurality of driving courses, and the user selects a driving course with a switch or the like, thereby performing a driving course according to the use of the user.
[0004]
In a conventional dishwasher, as disclosed in Japanese Patent Application Laid-Open No. 1-158927, in order to prevent a large amount of gas in the washing space from being discharged as steam, the control means performs a rinsing operation and a drainage operation. When the cleaning and drying unit is operated in the order of the operation and the drying operation, the discharge amount of the gas from the cleaning space is smaller than the discharge amount for the drying operation until a predetermined time elapses from the start of the drying operation. In addition, an exhaust fan as a ventilation means for drying is operated.
Then, the control means operates an exhaust fan as a drying ventilation means so that, when a predetermined time has elapsed from the start of the drying operation, the amount of gas discharged from the cleaning space becomes the amount of drying operation. .
[0005]
To add an explanation, in the rinsing operation, the object to be cleaned is rinsed with the rinsing water heated by the heating means, so after the rinsing operation, the inside of the cleaning space is in a high-temperature and high-humidity state. .
Therefore, after performing the draining operation, from the start of the drying operation, when the drying ventilation means is operated such that the amount of gas discharged from the cleaning space becomes the amount for the drying operation, the gas in the cleaning space becomes steam. Large amounts will be emitted.
Therefore, in the conventional dishwasher, the amount of gas discharged from the washing space is set to be smaller than the amount for the drying operation for a period from the start of the drying operation until a predetermined time elapses. Thus, the amount of gas discharged from the cleaning space is prevented from being discharged in large quantities as steam.
[0006]
By the way, if a large amount of gas in the washing space is discharged as steam, the large amount of steam is directly applied to the user, causing discomfort to the user or the large amount of steam applied to the wall around the dishwasher. However, inconvenience such as dew condensation on the wall surface occurs.
[0007]
[Problems to be solved by the invention]
However, in the above-mentioned conventional dishwasher, the control unit controls the discharge amount of gas from the cleaning space to be smaller than the discharge amount for the drying operation until a predetermined time has elapsed from the start of the drying operation. Since the drying ventilation means is operated, a desired drying effect cannot be expected until a predetermined time elapses from the start of the drying operation, and a problem arises in that the drying time of the object to be cleaned is prolonged.
[0008]
The present invention has been made in view of such a point, and its object is to eliminate the inconvenience of giving a user discomfort and to prevent inconvenience such as dew condensation on a wall surface around a dishwasher, and to eliminate the problem. An object of the present invention is to provide a dishwasher capable of shortening a drying time of a washed product.
[0009]
[Means for Solving the Problems]
In order to achieve this object, according to the first aspect of the present invention, a cleaning operation for cleaning an object to be cleaned in a cleaning space with a cleaning liquid, which is stored in a rinse water storage section and heated by a heating means. A rinsing operation for rinsing the object to be washed with rinsing water, a draining operation for draining the rinsing water stored in the rinsing water storage unit, and supplying drying air into the cleaning space by a ventilation means for drying. Cleaning and drying means for performing a drying operation for discharging gas in the cleaning space out of the apparatus; and control means for controlling the operation of the cleaning and drying means, wherein the control means includes the cleaning operation and the rinsing operation. In the dishwasher configured to operate the washing and drying unit in the order of the drainage operation and the drying operation,
The control means, when operating the washing and drying means in the order of the rinsing operation, the drain operation, and the drying operation, during the drain operation, the discharge amount of gas from the cleaning space is smaller than the discharge amount for the drying operation. The drying ventilation means is configured to be operated so as to have a small emission amount for the preceding operation.
[0010]
That is, the control means, when operating the washing and drying means in the order of the rinsing operation, the draining operation, and the drying operation, the drying ventilation so that the amount of gas discharged from the washing space during the draining operation becomes the amount of the preceding operation. By activating the means, the gas in the washing space which has become hot and humid after the rinsing operation can be gradually discharged before the drying operation is started.
Therefore, since the gas in the washing space which has become hot and humid is gradually discharged during the draining operation, the control means performs the drying when the washing and drying means is operated in the order of the rinsing operation, the draining operation, and the drying operation. From the start to the end of the operation, even if the drying ventilation means is operated so that the amount of gas discharged from the washing space is equal to the amount for drying operation, a large amount of gas in the washing space is discharged as steam. Can be prevented.
[0011]
From the above, when operating the washing and drying unit in the order of the rinsing operation, the draining operation, and the drying operation, the control unit controls the discharge amount of gas from the cleaning space to be the discharge amount for the preceding operation during the drainage operation. By operating the drying ventilation means, and by operating the drying ventilation means so that the amount of gas discharged from the cleaning space is equal to the drying operation discharge amount from the start to the end of the drying operation, the gas in the cleaning space is reduced. A desired drying effect can be expected from the start to the end of the drying operation while preventing a large amount of steam from being discharged.
Therefore, there is provided a dishwasher capable of shortening the drying time of an object to be washed while eliminating inconveniences such as discomfort to a user and dew formation on a wall around the dishwasher. I can do it.
[0012]
According to the invention as set forth in claim 2, a rinse water temperature setting means for changing and setting a rinse water temperature of the rinse water heated by the heating means is provided, and the control means is heated by the heating means. The heating unit is operated so that the temperature of the rinse water is the rinse water temperature set by the rinse water temperature setting unit, and the rinse water temperature set by the rinse water temperature setting unit is high. The emission amount for the preceding operation is configured to be changed and set such that the emission amount for the preceding operation becomes smaller as the amount of the preceding operation decreases.
[0013]
That is, the control means, when operating the washing and drying means in the order of rinsing operation, drainage operation, drying operation, as the rinse water temperature set by the rinse water temperature setting means is higher, during drainage operation, from the washing space, The drying ventilation means can be operated so as to reduce the amount of gas discharged.
Therefore, the rinsing water temperature set by the rinsing water temperature setting means is increased, so that after the rinsing operation is completed, the gas in the hot and humidified washing space can be discharged little by little during the drain operation. As a result, inconveniences such as discomfort to the user and dew condensation on the wall surface around the dishwasher can be eliminated exactly.
[0014]
According to the invention as set forth in claim 3, the control means is configured to control the cleaning and drying means so that the higher the rinse water temperature set by the rinse water temperature setting means, the longer the operation time of the drainage operation is. Is configured to control the operation of the vehicle.
[0015]
That is, the control means, when operating the washing and drying means in the order of the rinsing operation, the drain operation, and the drying operation, the higher the rinsing water temperature set by the rinsing water temperature setting means, the more the cleaning operation is performed prior to the start of the drying operation. The time for gradually discharging the gas in the space can be lengthened.
Therefore, when the rinsing water temperature set by the rinsing water temperature setting means is increased by the cooperative action with the second aspect, when the inside of the washing space becomes hotter and humid after the rinsing operation, drying is performed. Prior to the start of the operation, while the gas in the cleaning space is discharged little by little, the gas can be surely discharged before the drying operation is started.
As described above, inconveniences such as giving the user discomfort and dew condensation on the wall surface around the dishwasher can be accurately and reliably eliminated.
