Further, it has a drain pump (not shown) for discharging the cleaning water out of the apparatus, a blower 64 for feeding outside air to the cleaning tank 63, and an exhaust port 65 for exhausting moisture inside the cleaning tank 63.

Further, a heater 66 for heating cleaning water or outside air is used.
A cleaning pump 62, a heater 66, a drainage pump,
The operation is controlled by a control device 67 that controls the blower 64 and the like. Further, the control device 67 allows selection of several operation methods in which the cleaning time and the cleaning or rinsing temperature are changed. The lid 68 having the exhaust port 65 on the front surface has a convex portion 69 on the outer periphery. Further, a seal portion 70 is formed on the outer peripheral portion of the opening 71 on the front surface of the cleaning tank 63, and the end face of the opening 71 is on a substantially vertical plane. The convex portion 69 and the seal portion 70 are substantially U-shaped, including the upper edge portion and the left and right outer peripheral portions, and the lower end portion is sealed with another member.

[0004] Handles, switches, locking members, and the like are provided as locking devices 72 and 73 on the upper edge portion of the lid 68 and the upper portion 63a of the main body. Hereinafter, the actual driving method will be described. In such a dishwasher / dryer, first, the lid 68 is opened, the tableware basket 60 is pulled out forward, and the tableware to be washed is stored in the tableware basket 60. This situation is shown in FIG. Then, the tableware basket 60 containing the object to be washed is pushed into a predetermined position of the washing tank 63, the detergent is introduced, and the operation is started.

When the operation is started, first, the cleaning pump 62
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 is performed. Following the water supply step, while being pressurized by the cleaning pump 62 and heated to the first predetermined temperature by the heater 66,
The main washing step is performed in which the washing water is sprayed from the spray nozzle 61 together with the detergent. The cleaning water is sprayed vertically or obliquely upward from the spray nozzle 61. Further, the cleaning nozzle 61 is rotated substantially horizontally by the jet reaction force. The dishes are washed by the action of the collision force, detergent, heat, etc. of the washing water jetted from the rotating washing nozzle 61 in this manner.

After the temperature of the washing water rises to a predetermined temperature, and after a main washing step for a predetermined time, the washing water containing dirt washed off from the dishes and the like is discharged to the outside of the machine by a drain pump. . Subsequently, a water supply step of newly supplying cleaning water, a rinsing step of jetting cleaning water from the cleaning nozzle 61 to rinse dishes washed with detergent or garbage (the dirt attached to the dishes is also called garbage), The draining step is repeated four times consecutively, and the cleaning step is completed.

In order to perform the subsequent drying step in a short time, the final rinsing step is a heating rinsing step in which the cleaning water is heated by the heater 66 to a second predetermined temperature. Here, generally, the first predetermined temperature is often lower than or equal to the second predetermined temperature. Now, following the washing step, a drying step of operating the blower 64 and the heater 66 to discharge the moisture in the washing tank 63 and heating and evaporating the water droplets of the washing water attached to the tableware is performed.

In this drying step, the air inside the cleaning tank 63 is exhausted from the exhaust port 65 by sending air outside the apparatus into the cleaning tank 63 by the blower 64. At the same time, a necessary drying performance is obtained by operating the heater 66 appropriately to make the outside air warm air and to dry water droplets on the object to be cleaned.

It is discharged from 5. That is, the energy efficiency in this step is low. Therefore, the high-temperature warm air and its heat energy are discharged from the exhaust port 65 to the outside of the machine.

[0010] Second, even for objects to be cleaned that are lightly soiled and can be easily washed with tap water, they are stored in the dish basket 60 in the same manner as other objects to be cleaned that are strongly soiled. Then, cleaning is performed by the same operation method. Therefore, by accommodating the tableware for which the drying effect can be obtained as described above, the capacity of the object to be cleaned that can be stored in the tableware basket 60 is limited.

Thirdly, the exhaust port 65 is disposed on the front surface of the lid 68, so that the noise inside the cleaning tank 63 generated in the cleaning step is easily leaked to the outside of the machine. It is. In order to reduce the cleaning noise, it is necessary to provide an opening / closing means for the exhaust port 65 so as to be hermetically sealed in the cleaning step and exhaust the air in the drying step. In order to solve the second problem, Japanese Patent Application Laid-Open No. Hei 7-329 discloses a method in which a large amount of tableware is collectively washed by dividing a washing tank into upper and lower chambers and opening and closing a boundary wall thereof. It has been proposed that water can be saved by only one room with a small amount of tableware. However, this proposal does not utilize heat energy dropped for washing dishes or hot air energy for drying more effectively.

The present invention solves the above-mentioned problems of the conventional dishwasher / dryer. In particular, an object of the present invention is to provide a dishwasher capable of effectively utilizing energy and mechanical components in a drying process and solving a problem relating to noise during a washing operation.

The convex portion 10 and the seal portion 11 abut to open and close the opening 9 of the cleaning tank 2. It is. A handle, a switch, a locking member, and the like are provided as a locking device on the upper edge portion and the upper portion of the main body of the lid 8.

A drying cabinet 12 for storing tableware, cooking utensils and the like is arranged above the washing tank 2. Drying cabinet 12
The drying cabinet 12 is placed on the upper part separately from the washing tank 2 and the main body. 13 is a washing tank 2
Is an exhaust duct connecting the exhaust port 7 and the drying cabinet 12 of
The exhaust duct 13 is detachable from the exhaust port 7. 14 is a drawer for storing tableware and the like, 15 is a second exhaust port, and 16 is a handle of the drawer 14. The drawer 14 can be smoothly inserted into and removed from the drying cabinet 12 by the side guide rails 14a (detailed drawings are omitted).

Reference numeral 17 denotes a heater for heating the cleaning water in the cleaning step, and heats the air in the drying step. Reference numeral 18 denotes a control device that controls operations of the cleaning pump 4, the blower 6, the heater 17, and the like. Next, the operation as the dishwasher of the first embodiment will be described. However, the operation method of the cleaning pump 4, the drain pump 5, the blower 6, the heater 17 and the like in the cleaning step and the drying step is basically almost the same as the conventional one, and therefore, the characteristic operation will be mainly described. .

First, among the objects to be washed such as tableware and cooking utensils, those to which light dirt is attached and which can be easily washed with warm water or tap water and a detergent are washed by hand and then drained. , And is stored in the drying cabinet 12. On the other hand, objects to be cleaned to which ordinary strong dirt has adhered can be arranged in the tableware basket 2 and stored in the cleaning tank 2.
Thereafter, the detergent is put into the cleaning tank 2 and the cleaning process is operated in accordance with a command from the control device 18. During cleaning, pressurized cleaning water is injected into the cleaning tank by the cleaning means including the cleaning pump 4 and the cleaning nozzle 3, and is one of the main sound sources of cleaning noise. In this embodiment, the cleaning tank 2
The noise inside the device passes through the drying cabinet 12 from the exhaust port 7 through the exhaust duct 13 and leaks out of the machine through the second exhaust port 15. However, the noise level is attenuated and reduced in the middle route as compared with the level at the exhaust port 7.

Finally, after the washing step, a drying step is performed. In this step, the heater 17 is energized and the blower 6 is operated, so that warm air is sent into the cleaning tank 2 from outside the machine.
The hot air evaporates water droplets on the object to be cleaned, and most of the hot air is sent from the exhaust port 7 to the drying cabinet 12 through the exhaust duct 13 at a high temperature. The hot air dries the dishes in the drawer 15 and the exhaust gas is discharged from the second exhaust port 15 to the outside of the machine.

From the above operation, the following characteristic effects can be obtained. First, a tableware that needs to have a drying effect and a tableware that needs to be washed and dried are stored in a drying cabinet 12 and a washing tank 2.
And can be stored separately. Therefore, the number of items to be washed stored in the tableware basket 1 is reduced with respect to the same amount of tableware, making it easier to put the items into the tableware basket 1, thereby improving usability. In addition, since the number of objects to be cleaned is small, the heat energy required for heating together with the cleaning water in the cleaning step can be reduced, and the electricity bill can be saved. Of course, since the time for heating can be shortened, the operation time is shortened.

Secondly, the operation noise during the washing process is reduced when the washing nozzle 3 has the same injection pressure.
Therefore, it is possible to increase the injection pressure to increase the cleaning power, and at the same time, reduce the cleaning noise to the same level or less as before. Third, the warm air blown by the heater 17 and the blower 6 is used not only for drying the object to be cleaned in the cleaning tank 2 but also for drying the dishes in the drying cabinet 12. Therefore, the hot air acts on the dishes in both the washing tank 2 and the drying cabinet 12, so that the heat energy of the hot air is sufficiently given to each tableware. For this reason, the temperature of the exhaust gas from the second exhaust port 15 is low. That is, the use efficiency of heat energy in this step is high.

Of course, a large amount of cleaning water adheres to the cleaning tank 2 as water droplets other than the cleaning object in the cleaning step. Since the cleaning tank 2 requires a larger amount of heat energy for drying than the drying cabinet 12, the heat energy of the heater 17 is used efficiently, and energy can be saved. In this embodiment, the exhaust duct 13 can be removed from the exhaust port 7 as shown in FIG. In this way, when the washing / drying operation is repeated in the washing tank 2 thereafter, it is possible to prevent the drying chamber 12 from being affected by the exhaust gas.

As another embodiment, as shown in FIG.
At least one or more openings 14b in the bottom of drawer 14a
Is provided, and one end of the exhaust duct 13 can be formed at substantially the same height as the bottom surface 12b of the drying cabinet 12a. At this time, the drying cabinet 12a, that is, the drawer 1
The water drops dropped on 4a can be collected into the cleaning tank 2 through the exhaust duct 13. If the amount of the water droplet is large, it is used by being mixed with the washing water in the washing step.

It is not necessary that the exhaust duct 13 and the exhaust port 7 are separate bodies, and one end of the exhaust duct 13 may be the exhaust port 7 itself. (Embodiment 2) This embodiment has a tableware basket 1, a washing tank 2, a washing nozzle 3, a washing pump 4, a blower 6, and the like, as in the first embodiment. Description is omitted.

As shown in FIG. 4, the lid 20 and the cleaning tank 2
There is a convex portion 22 and a seal portion 23 with respect to the opening 21, and an exhaust port 24 is arranged at the upper edge of the lid 20.
Further, the second embodiment is different from the first embodiment in that an exhaust duct 25 for guiding exhaust is disposed opposite to the exhaust port 24. 26 is an elastic bellows-like connecting member, 27 is tableware,
A drying cabinet for storing cooking utensils and the like, 28 is a drawer provided inside the drying cabinet 27, and 29 is a second exhaust port provided on the front surface of the drawer 28. Reference numeral 30 denotes a control device that controls operations of the cleaning pump 4, the blower 6, the heater 14, and the like.

The characteristics of the second embodiment are as follows.
This is to prevent dripping of cleaning water due to opening and closing of the lid during the cleaning step and the drying step, and to improve usability. In the cleaning step, particularly in the heating rinsing step, the rinsing temperature is controlled to about 60 ° C. (about 80 ° C. depending on the selection of the operation course) under the control of the control device 30. At this point, the inside of the cleaning tank 2 is filled with high-temperature and humid air and the injected cleaning water.
At 4, high-temperature water droplets that have entered and water droplets that have condensed from moisture are attached. In the drying step, the blower 6 blows air outside the machine into the cleaning tank 2 and controls the heater 14 as appropriate to discharge high-temperature, humid air inside the cleaning tank 2 from the exhaust port 7. At the same time, the hot air is used to evaporate water droplets attached to the object to be cleaned.

First, a lid 2 is provided above the top surface of the washing tank 2.
Since the exhaust port 24 is disposed at the upper part of the exhaust port 24, the exhaust port 24 faces upward when the lid 20 is opened as shown in FIG. Can be prevented. Second, the connection can be reliably established in conjunction with the opening and closing of the lid 20 and the operation of the locking device. In the second embodiment, the exhaust port 24 and both ends of the exhaust duct 26 are in contact with each other.
It can be further fitted.

Thirdly, as shown in FIG. 5, since the opening 21 is inclined, the space distance L1 between the tableware and the opening 21 of the washing tank 2 is large, so that the storage and removal of the object to be washed is performed. , Excellent usability. Moreover, by storing tableware of various shapes and sizes separately in the washing tank 2 and the drying cabinet 27, a large amount of tableware can be dried at one time. That is, usability is improved mainly in the storage operation.

Although the exhaust duct 25 and the connecting member 26 are detachable, it goes without saying that they may be integrated. (Embodiment 3) In this embodiment, the basic configuration of a tableware basket 1, a cleaning tank 2, a cleaning nozzle 3, a heater 14, and the like is the same as that of the second embodiment, and a description of the basic configuration will be omitted.

As shown in FIG. 6, the exhaust port 31, this exhaust port 3

3 are provided. In the present embodiment, the exhaust duct 32 or the second
The second embodiment differs from the first and second embodiments in that a passage switching means 35 for selecting a passage to exhaust air from at least one of the exhaust ducts 33 is provided.

FIG. 7 shows an operation method by the passage switching means 35 in the third embodiment. The control of the actual operation is performed by the control device 36 that controls the operation of the cleaning means, the blower 6, and the like. First, in the cleaning step, the exhaust duct 32 is closed by the passage switching means 35, and the second exhaust duct is opened. The noise generated in the cleaning tank 2 during the cleaning and the noise caused by the injection of the cleaning water are discharged from the second exhaust duct 33.

Next, in the drying step, the exhaust duct 32 is opened by the passage switching means 35, and the second exhaust duct 33 is also opened. The hot air generated by the air blower 6 and the energization of the heater 14 is sent to the drying cabinet 27. Exhaust is performed by the operation method controlled in this manner from the second exhaust duct 33 and the second exhaust port 29 so that the moisture generated in the cleaning tank in the cleaning step is not sent to the drying chamber 27, but is required in the drying step. Accordingly, the object to be cleaned in the cleaning tank 2 can be dried with warm air.

Next, the characteristics of the operation of the dishwasher of the third embodiment as an operating method will be supplemented. First, the passage switching means 35 can select whether or not to send exhaust gas from the main body to the drying cabinet 27. In other words, as described above, in order to exhaust air from the second exhaust duct 33 to the outside of the machine in the washing process and send hot air to the drying cabinet 27 for drying,
The passage switching means 35 can blow air from the exhaust duct 32.

Secondly, since the exhaust air after the washing operation is humid, the second exhaust duct 33 can be used even during the subsequent drying operation.
Discharge for a more predetermined time. As a result, only the hot air having a particularly low humidity is supplied from the exhaust duct 32 to the drying chamber 27.
The feature is that it can be sent to The second exhaust duct 33 is open during the drying process, but may be closed. In this case, the whole hot air is discharged from the second exhaust port 27.

Therefore, as another embodiment, the control device 3
In 6, the passage switching means 35 performs an operation method in which exhaust gas is not exhausted to the drying cabinet 27 for a predetermined time immediately after the washing step of injecting washing water. As a result, it is possible to supply only the hot air to the drying cabinet 27 and dry it, if necessary, without sending the moisture generated in the cleaning tank 2 in the cleaning step to the drying cabinet 27. Of course, depending on the size of the washing tank 2 and the washing temperature, the above-mentioned predetermined time for discharging moisture is almost constant.

In the third embodiment, one exhaust port and one exhaust duct are provided.
Although it is assumed that each of them has a plurality of exhaust ports, it is only necessary to close the exhaust ports to the exhaust duct connected to the drying cabinet at least. In the second and third embodiments, the shapes of the lid and the opening may be substantially vertical as in the related art. In short, any structure may be used as long as it can be connected to the drying cabinet by an exhaust duct that can be reliably connected to the exhaust port when the lid is opened and closed.

Another operation method is to store dishes, cooking utensils, and the like in the drying cabinet 27 so that they can be dried by the drying operation of the main part of the dishwasher below. is there. As described above in each of Embodiments 1 to 3, the drying function as a drying cabinet can be exhibited by effectively utilizing the heater 14 and the blower 6. In addition, the energy used can be more effectively utilized.

Even if no special operation instruction is given, it is normally brought into contact with high-temperature and high-humidity air of about 60 ° C. or higher, and then dried with warm air, so that a sanitary condition can be maintained. In such a case, the exhaust duct 13 of the first embodiment need not be detachable.

Needless to say, a dedicated heater may be provided for drying in the drying cabinet 12 and used in combination. In addition, as in each of Examples 1 to 3 described above, if there are the drying cabinets 12 and 27 at the top,
When the lids 8 and 20 of the lower washing tank 2 are opened, the drying cabinet 1 is opened.
Water dropped from the drawers 2 and 27 can be easily collected in the lids 8 and 20. Except for such a point, it goes without saying that the washing tank 2 and the drying cabinets 12 and 27 may be arranged on the left and right even in an upside down arrangement.
