  A conventional dishwasher will be described with reference to FIG. As a configuration for cleaning and drying the tableware, the table includes a tableware basket 60 for storing the tableware to be cleaned, a cleaning nozzle 61 for injecting cleaning water, a cleaning pump 62 for pressurizing the cleaning water, and a cleaning tank 63. Yes. In addition, it has a drain pump 64 that discharges cleaning water to the outside of the machine, a blower 65 that sends outside air to the cleaning tank 63, and an exhaust port 66 that exhausts moisture inside the cleaning tank 63.
[0003]
  Further, a heater 67 for heating the cleaning water and the outside air is provided, and the operation is controlled by a control device 68 that controls the cleaning pump 62, the heater 67, the drainage pump 64, the blower 65, and the like. Furthermore, this control device allows selection of several operating methods in which the cleaning time and the cleaning or rinsing temperature are changed.
[0004]
  In such a dishwasher, the dish to be cleaned is stored in the dish basket 60, and the detergent is put in to start the operation. When the operation is started, first, a water supply step of supplying a predetermined amount of cleaning water to the cleaning tank 63 for stabilizing the operation of pressurizing the cleaning water by the cleaning pump 62 is executed. Subsequent to the water supply process, a main cleaning process is performed in which the cleaning water is sprayed from the spray nozzle of the cleaning nozzle 61 together with the detergent while being pressurized by the cleaning pump 62 and heated to the first predetermined temperature by the heater 67.
[0005]
  The washing water is jetted vertically or obliquely upward from the jet nozzle of the washing nozzle 61. Further, the cleaning nozzle 61 is rotated substantially horizontally by the jet reaction force. The tableware is washed by the action of the collision force, detergent, heat, etc. of the washing water sprayed from the washing nozzle 61 rotating in this way.
[0006]
  When the cleaning water rises to a predetermined temperature and passes through a main cleaning process for a predetermined time, the process enters a draining process in which cleaning water containing dirt washed off from tableware and the like is discharged to the outside by a drain pump. Subsequently, a water supply process for newly supplying cleaning water, a rinsing process for spraying cleaning water from the cleaning nozzle 89 in order to rinse the dishes contaminated with detergent and residual vegetables (soils attached to the dishes are also referred to as residual vegetables), The draining step is continuously repeated four times to complete the cleaning step.

  In addition, in order to perform the drying process of the next process in a short time, the final rinsing process is a heating rinsing process performed while heating the cleaning water to the second predetermined temperature by the heater 67. In general, the first predetermined temperature is often equal to or lower than the second predetermined temperature.
[0008]
  Subsequent to the cleaning process, the blower 65 and the heater 67 are operated to discharge moisture in the cleaning tank 63, and a drying process for heating and evaporating water droplets of the cleaning water adhering to the tableware is performed.
[0009]
[Problems to be solved by the invention]
  The above-described dishwasher having the conventional configuration has the following problems with respect to the drying process following the cleaning process. First, in the cleaning process, particularly in the heating and rinsing process, the cleaning water is heated to a high temperature of about 60 ° C. to 80 ° C. Therefore, the cleaning tank 63 is filled with high-temperature and humid air at the same temperature. Yes. With the start of the drying process, this is discharged from the exhaust port 66 to the outside by the blower 65. There has been a problem that the device may be damaged due to moisture condensation due to the moisture being released toward the device close to the exhaust port 66 and indoors. Of course, the comfort is reduced by increasing the humidity in the room where the device is installed.
[0010]
  As a drying method for solving this problem, a dehumidifying method has been proposed in JP-A-63-318925 and JP-A-3-236823, but the structure of the drying mechanism is complicated and expensive. It becomes. As another conventional technique, Japanese Patent Laid-Open No. 8-52103 prevents moisture from coming into contact with a sink in which equipment is installed by simultaneously blowing indoor air located above the exhaust from the cleaning tank. Although a blower mechanism is shown, a new blower path is required.
[0011]
  Secondly, in the drying process, the moisture in the washing tank is exhausted as it is to the outside of the machine. Therefore, if the operation method at a higher rinsing temperature is performed, the exhaust at a higher temperature will be discharged. This is likely to cause more damage. As a solution to this problem, Japanese Patent Application Laid-Open No. 9-29931 discloses that the exhaust gas from the dishwasher / dryer is discharged to the water distribution pipe, but requires a new air passage connection.
[0012]
  This invention solves the subject which the above conventional dishwashers have. In particular, it is an object of the present invention to provide a dishwasher that can reduce the temperature and humidity of exhaust gas by providing exhaust assisting means for mixing outside air to the exhaust means having a blower and an exhaust port.

[0030]
【Example】
  Embodiments of the present invention will be described below with reference to the drawings.
[0031]
  Example 1
  In FIG. 1, 1 is a tableware basket for storing objects to be cleaned such as tableware and cooking utensils, 2 is a cleaning tank, 3 is a cleaning nozzle that jets cleaning water and rotates substantially horizontally, and 4 is a cleaning that pressurizes the cleaning water. It is a pump. 5 is a drainage pump for discharging the washing water to the outside of the machine, and 6 is a blower for exhausting moisture from the washing tank 2. Reference numeral 7 denotes an exhaust port for exhausting moisture from the cleaning tank. The blower 6 and the exhaust port 7 are the main exhaust means.
[0032]
  Further, 8 is an exhaust passage connecting the inside of the cleaning tank 2 and the exhaust port, 9 is an outside air intake port communicating with the exhaust passage, and 10 is a mixed exhaust passage through which the exhaust from the cleaning tank 2 and the outside air are mixed. These are called exhaust assisting means 11. A heater 12 mainly heats cleaning water in the cleaning process, and heats air in the drying process. A control device 15 controls the operation of the cleaning pump 6, the blower 6, the heater 12, and the like.
[0033]
  Next, the operation of the dishwasher of this embodiment will be described. Since the operation method of the cleaning process is basically the same as the conventional one, the description thereof is omitted. What is characteristic in the present embodiment is the operation of the exhaust assisting means 11 in the drying process.
[0034]
  In the cleaning process, particularly in the heating and rinsing process, the rinsing temperature is heated to about 60 ° C. (about 80 ° C. depending on the selection of the operation course) as controlled by the controller 15. When the set temperature is reached, the rinsing process is terminated, the washing water is discharged out of the apparatus by the drain pump 5 and the process proceeds to the drying process.
[0035]
  In the drying process, the blower 6 blows air outside the machine into the cleaning tank 2, so that high-temperature and humid air inside the cleaning tank 2 is sent into the ventilation path 8. In the exhaust assisting means 11, the passage area is reduced at the tip of the ventilation path 8, and the flow of air is increased. In the mixed exhaust passage 10 opposed to the front end outlet, air from the outside air intake port 9 is mixed with the exhaust gas and is discharged to the exhaust port 7. That is, the temperature and humidity of the exhaust can be reduced by the amount of outside air mixed therein.
[0036]
  In addition, since the wind power of the blower 6 is used as a driving source, it is a configuration that automatically mixes the necessary amount again when necessary according to the wind power, that is, in conjunction with the operation of discharging moisture. It can be set as the dishwasher which the effect is acquired reliably.
[0037]
  As another exhaust assisting means, an exhaust that communicates with the outside of the machine is provided in an exhaust passage that connects the inside of the cleaning tank and the exhaust port, and exhaust that reduces and expands the passage area of the exhaust passage relative to the opening. Even if it has a passage adjusting means, that is, a duct that sucks in outside air, there is no rotation mechanism portion, and an excellent effect can be obtained with a simple configuration.
[0038]
  In any case, the exhaust assisting means using the wind power of the exhaust as such as the driving source is completely interlocked with the operation of the exhaust, and an effect can be obtained when necessary.
[0039]
  (Example 2)
  In the present embodiment, the basic configuration is similar to that of the first embodiment, and includes a tableware basket 1, a cleaning tank 2, a cleaning nozzle 3, a cleaning pump 4, and a drainage pump 5, and description of the basic configuration is omitted.
[0040]
  As shown in FIG. 3, the blower 20 and the exhaust port 21 are the main exhaust means, but differ from the first embodiment in the following points. First, the exhaust passage 22 communicates with the first impeller 23. Moreover, it has the 2nd impeller 24, and the exhaust assistance means 28 is formed by these.
[0041]
  As shown in FIG. 4, the exhaust assisting means 28 includes a first casing 23 a that houses a first impeller 23 that rotates with the air in the cleaning tank 2 from the exhaust passage 22. It has an outlet 25. A second impeller 24 is attached to the rotating shaft of the first impeller 23, and there is a second casing 24 a that houses the second impeller 24, and a second air discharge port 26 is provided. have. Reference numeral 27 denotes an outside air intake for guiding air outside the machine to the second impeller 24.
[0042]
  In the present embodiment, the first casing 23a is substantially circular as shown in FIG. 5, and the second casing 24a is also the same.
[0043]
  The features of the operation of the dishwasher of this embodiment are as follows. In the drying process, the blower 20 blows air outside the machine into the cleaning tank 2, so that high-temperature and humid air inside the cleaning tank 2 is sent to the ventilation path 22. At this time, the exhaust assisting means 28 causes the air in the ventilation path 22 to reach the first impeller 23, rotate it, and be discharged from the first air outlet 25. And the 1st impeller 23 rotates by ventilation, and the 2nd impeller 24 arrange | positioned at the same rotating shaft rotates. Due to the rotation of the second impeller 24 and the action of the second casing 24 a, outside air is sucked from the outside air inlet 27 and discharged from the second air outlet 26.
[0044]
  Then, the moisture from the first air discharge port 25 and the outside air from the second air discharge port 26 are mixed and discharged from the exhaust port 21. In this way, the temperature and humidity of the air exhausted from the exhaust port 21 are both reduced from the state of the air inside the cleaning tank 2, so that the air to the peripheral equipment in the room where the present embodiment is installed can be reduced. Damage is reduced.
[0045]
  As another embodiment of the present invention, as shown in FIG. 6 and FIG. 7, the first casing 23c and the second casing 24c with respect to the first impeller 23b and the second impeller 24b. Thus, it goes without saying that the first air discharge port 25d and the second air discharge port 26d can be formed efficiently by forming the discharge portion in the tangential direction at the outer peripheral portion. Of course, various types can be selected for the positional relationship and arrangement between the impeller and the casing.
[0046]
  In other words, regardless of the form of the impeller and the casing, it is sufficient if outside air is mixed using wind power as a driving source.
[0047]
  (Example 3)
  In this embodiment, the basic configuration of the tableware basket 1, the washing tank 2, the heater 12, and the like is the same as that of the third embodiment, and the description of the basic configuration is omitted. The exhaust assisting means 38 shown in FIG. 8 is different in that it is configured to be detachable.
[0048]
  The exhaust assisting means 38 includes an exhaust passage 32 that communicates with the cleaning tank 2, a first impeller 33, a second impeller 34, and a first air discharge port 35 that discharges air with each impeller. A second air discharge port 36 and an outside air intake port 37 are provided. This configuration and operation are basically the same as those in the second embodiment. Also, the effect of the operation is the same.
[0049]
  In this embodiment, as shown particularly in FIG. 9, the main body 39 of the exhaust auxiliary means 38 is detachably attached to the mounting portion 40 of the exhaust passage 32, and can be removed and cleaned easily at the end of operation. It is. In this embodiment, the main body 39 and the mounting portion 40 are fitted by the difference between the outer diameter and the inner diameter, but of course, a configuration such as bayonet coupling or magnet fixing is also possible.
[0050]
  Furthermore, the exhaust temperature reducing effect can be selected by cooling the exhaust assist means 38 in advance with a refrigerator or the like. Of course, the exhaust port 31 may have a rib 31d, a mesh structure, or a louver shape similar to the conventional one.
[0051]
  Example 4
  In this embodiment, the basic configuration of the tableware basket 1, the washing tank 2, the heater 12, and the like is the same as that of the third embodiment, and the description of the basic configuration is omitted. The exhaust assisting means 38 is the same as that of the third embodiment, and the effect by its operation is also the same.
[0052]
  In this embodiment, as shown in FIG. 10, the difference is that a cold insulating member 45 for lowering the exhaust temperature is detachably provided. Of course, it may be integrated. The cold insulating member 45 is made of a material having a large heat capacity, and has a rib 45a, so-called radiating fin shape, for effectively performing heat exchange, as is apparent from FIG. The exhaust is exhausted from the space 45b formed by the exhaust port 31 and the rib 45a.
[0053]
  The feature of the configuration of the present embodiment is that the effect of further reducing the exhaust temperature can be obtained in the drying process by storing the cold insulation member 45 in a refrigerator. That is, the exhaust gas is mixed with the outside air by the exhaust assisting means 38, and the temperature and humidity are reduced, and the temperature is further lowered by the low temperature rib 45a.
[0054]
  (Example 5)
  In this embodiment, the basic configuration of the tableware basket 1, the washing tank 2, the heater 12, and the like is the same as that of the third embodiment, and the description of the basic configuration is omitted. The exhaust assisting means 38 is the same as that of the third embodiment, and the effect by its operation is also the same.
[0055]
  In the present embodiment, as shown in FIG. 11, the detecting means 49 for detecting the attachment of the exhaust assist means 38 has a magnet 50 and a Hall element 51 as an element for detecting the magnet. The control device is different in that the driving method is controlled in conjunction with the detection signal. Of course, a microswitch or the like can be considered as the detection means.
[0056]
  The structural feature of this embodiment is that the operation method of the drying process is switched when the exhaust assisting means 38 is not mounted as shown in FIG. 31a is a second exhaust port, 31c is a rib provided in the second exhaust port 31a, and is the same rib provided in the conventional exhaust port 66.
[0057]
  First, the moisture in the cleaning tank 2 is naturally exhausted from the second exhaust port 31a without operating the blower 30 for a certain time from the start of the drying process. By this, moisture is discharged little by little and the influence on the peripheral equipment is reduced.
[0058]
  In addition, an operation method is performed in which the blowing capacity of the blower 30 is reduced from the normal state, the amount of exhaust per unit time is reduced, and the influence on peripheral devices is reduced. In addition, the required drying performance can be obtained by changing the operation time. Furthermore, the control device can be operated when the exhaust assisting means 38 is not attached, with the cleaning temperature or the heating rinse temperature being reduced compared to when the exhaust assisting means 38 is attached.
[0059]
  In this way, when the exhaust assisting means 38 is not attached, the temperature of the moisture exhausted in the drying process is reduced by reducing the heating temperature in the cleaning process and the heating rinse process to reduce the temperature of the air inside the cleaning tank 2. It is possible to realize an operation method with reduced noise. Still further, when the exhaust assisting means 38 is not attached and an operation method including a high temperature cleaning or rinsing operation temperature at which the operation temperature is equal to or higher than the predetermined temperature is selected, the control device starts the operation and starts the operation. It can also be stopped at times or in the middle. This prevents the high temperature and humidity from being discharged.
[0060]
  In any case, it is possible to obtain an operation method for reducing or preventing moisture discharged into the room according to the wearing state. Further, in the present embodiment, the rib 31c and the rib 31d are provided in each of the second exhaust port 31a connected to the exhaust assist means 38 from the exhaust passage 32 and the exhaust port 31 exhausted to the outside of the machine. And these ribs 31c and 31d are the shape which partitions each exhaust port finely, Comprising: Since a some opening is formed, it is called a filter part. If the pressure loss of the exhaust gas is small, a fine fiber filter may be used. As a result, the exhaust passes through the filter portion having a plurality of apertures formed by the ribs 31c or 31d regardless of the exhaust auxiliary means 38 being mounted, so that a large amount of exhaust is ejected vigorously. The effect of preventing this is obtained.
[0061]
  This effect can be obtained regardless of the configuration of the exhaust assisting means, specifically, the action of mixing outside air, etc., and the exhaust is at least one of which has a plurality of apertures. Since it passes through, it prevents the exhaust of a large air volume from being ejected vigorously.
[0062]
  Of course, in addition to this, the exhaust assisting means mixes the outside air with the exhaust wind using the wind power of the exhaust as a driving source. Therefore, in the normally mounted state, as shown in other embodiments, the temperature of the exhaust And has the effect of reducing humidity. And the influence on the peripheral device is further reduced.
[0063]
  In each of the above embodiments, a general dishwasher is assumed to be provided with a heater for heating washing water, but it is connected to a water heater so that the necessary hot water temperature can be obtained. It goes without saying that a similar dishwasher / dryer can achieve the same effect without a heater.
[0064]
