BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described in detail with reference to the accompanying drawings. FIG. 1 is a right side sectional view showing an internal configuration of a dishwasher according to an embodiment of the present invention. FIG. 2 shows a state in which the opening / closing door 6 is opened in order to explain the configuration inside the cleaning chamber 3.
It is a perspective view which partially cuts out and shows a dishwasher.

Referring to FIG. 2 while referring to FIG. 1, the dishwasher 1 includes a box-shaped washing room 3 having an open front surface for taking in and out of the dishes 2, an upper surface and both sides of the washing room 3. It has a cover 4 for covering the surface, a rear panel 5 attached to the rear of the cover 4 to form a rear surface of the dishwasher 1, and an openable and closable door 6 capable of closing the front opening of the washing room 3. I have. The tableware 2 as an object to be cleaned is set in a tableware basket 7 and stored in the cleaning room 3 through the front opening of the cleaning room 3.

An arm 8 for spraying water onto the tableware 2 in the tableware basket 7 is rotatably supported below the tableware basket 7 and substantially at the center of the bottom of the washing chamber 3. A plurality of nozzles 22 are formed on the upper surface of the arm 8, and water spouted upward from these nozzles 22 is sprayed on the tableware 2 to remove dirt attached to the tableware 2. In addition, the arm 8 is rotated by the reaction force of the water spouted from the nozzle 22 so that the fountain flow is evenly sprayed on the tableware 2 in the tableware basket 7.

As shown in FIG. 2, a heater 9 is provided on the right side of the arm 8 when viewed from the front. Specifically, the heater 9 is constituted by, for example, a sheath heater 9 formed in a substantially U-shape, and is disposed in a relatively narrow portion along the right side surface of the cleaning chamber 3. By arranging the heater 9 in the cleaning chamber 3 in such a manner, the following effects can be obtained.

For example, when small tableware such as a spoon falls through the grid of the tableware basket 7 and falls on the heater 9, the heater 9 may be damaged or the tableware may be discolored by the heat generated by the heater 9. . To prevent this,
It is conceivable that the grid of the portion of the tableware basket 7 located on the heater 9 is made fine so that even small tableware does not fall from the tableware basket 7. However, when the grid of the tableware basket 7 is made finer, the water flow spouted from the arm 8 (nozzle 22) is obstructed, and there is a possibility that the cleaning ability in that part is reduced. According to this embodiment, since the heater 9 is disposed in a relatively narrow portion in the cleaning chamber 3, compared with a case where the heater 9 is disposed so as to surround the base of the arm 8, for example, The portion that makes the grid fine can be reduced. Therefore, if tableware such as a large dish, which is relatively easy to remove, is set on a fine portion of the grid, washing of the table will not be uneven.

The heater 9 is not limited to the above-described substantially U-shaped sheathed heater 9, but may be, for example, a substantially W-shaped sheathed heater 9. In addition to the sheath heater 9, a heater may be provided outside the cleaning chamber 3, and the heater 9 may be formed of a member that conducts heat from the heater.
A water supply port 10 is formed on the rear surface of the cleaning chamber 3. A water supply pipe 11 is connected to the water supply port 10, and water sent from the unshown water supply or the like through the water supply pipe 11 is supplied into the cleaning chamber 3 through the water supply port 10. The water supplied into the cleaning chamber 3 is stored at the bottom of the cleaning chamber 3 and is heated by the heater 9 to become hot water. A water supply valve 12 that controls the supply of water to the cleaning chamber 3 is provided in the middle of the water supply pipe 11.

On the other hand, below the cleaning chamber 3, a pump device 1 is provided.
3 are provided. The pump device 13 includes a pump casing 16 that partitions the first pump chamber 14 and the second pump chamber 15 therein, a cleaning impeller 17 rotatably provided in the first pump chamber 14, and a second pump chamber. The pump 15 includes a drain impeller 18 rotatably provided in the pump 15, and a pump motor 19 for driving the cleaning impeller 17 and the drain impeller 18.

At the bottom of the washing chamber 3, a water collecting part 20 for collecting water in the washing chamber 3 is formed. The water collecting unit 20
The first pump chamber 14 is connected to the first pump chamber 14 via the connection pipe 21. At the time of washing and rinsing, the pump motor 19 is driven to rotate in a predetermined direction, and the washing impeller 17 provided in the first pump chamber 14 is rotated. Sent to The water sent to the arm 8 is jetted from the nozzle 22 formed on the upper surface of the arm 8 and sprayed on the tableware 2 as described above.

The water collecting section 20 is also connected to the second pump chamber 15 via a connecting pipe 23. When the washing or rinsing is completed, the motor is driven to rotate in the direction opposite to the predetermined direction, and the drainage impeller 18 provided in the second pump chamber 15 is rotated, so that the water is collected in the water collecting section 20. The water is discharged outside the machine through the drain pipe 24. In addition, when the water in the washing room 3 is collected in the water collecting part 20, residual vegetables and the like dropped from the tableware 2 at the time of washing are captured by the filter 25 provided above the water collecting part 20.

The dishwasher 1 has a function of drying the dishes 2 after washing, and a blower fan 26 for blowing air into the washing chamber 3 between the washing chamber 3 and the rear panel 5. Is provided. When the blower fan 26 is driven, external air is mainly taken into the intake air passage 28 from the first intake port 27 formed in the rear panel 5, and the air in the intake air passage 28 is forcibly introduced into the intake air passage 28. It is sent out to the road 29. Then, the air sent to the introduction air passage 29 is blown into the cleaning chamber 3 from an air outlet 30 formed on the rear surface of the cleaning chamber 3.

The outlet 30 is formed at the lower part of the rear surface of the washing chamber 3 and slightly to the right of the center when viewed from the front. The outlet 30 has a horizontally long rectangular shape including a lower side, left and right sides, and an upper side when viewed from the front. The heater 9 is disposed obliquely below the outlet 30. In this embodiment, the heater 9 is blown out from the outlet 30 into the cleaning chamber 3 by a wind direction adjusting mechanism (described later) provided in the introduction air passage 29. The blown air is mainly blown to the heater 9 as shown by a white arrow in FIG. Thereby, the air sent into the cleaning chamber 3 is efficiently heated by the heater 9.

The air heated by the heater 9 passes through the washing chamber 3 while drying the tableware 2 and is discharged from an exhaust port 31 (see FIG. 2) formed in the door 6. Therefore, in this embodiment, the washing room 3 accommodating the tableware 2 as the object to be dried, and the heater 9 disposed in the washing room 3
It can be said that the drying device is constituted by the blower fan 26 and the blower 26.

FIG. 3 is an enlarged sectional view showing the vicinity of the blower fan 26 provided at the rear of the cleaning chamber 3. Also,
FIG. 4 is a perspective view of the dishwasher 1 as viewed obliquely from the rear, and shows a state in which the rear panel 5 has been removed. Hereinafter, the configuration of the blower fan 26 will be described in detail with reference to FIGS. 3 and 4. The blower fan 26 has a spiral casing 3 attached to the rear surface of the washing chamber 3.
2, a blower impeller 33 rotatably provided in the spiral casing 32, and a fan motor 34 for rotating the blower impeller 33. The lower end of the spiral casing 32 extends to the outlet 30, and an inlet air passage 29 is formed by the spiral casing 32 and the rear surface of the cleaning chamber 3. Also, on the rear surface of the spiral casing 32,
Partition peripheral wall 35 until the leading edge contacts rear panel 5
The intake air passage 28 is formed by the peripheral wall 35 and the rear panel 5. Further, on the rear surface of the spiral casing 32, a communication port 36 that connects the upper part of the intake air path 28 and the introduction air path 29 is formed. Through the communication port 36, the intake air path 28 and the introduction air path are connected. Air can freely enter and exit between the air conditioner and the air conditioner.

The partition peripheral wall 35 includes a curved wall portion 37 having a substantially inverted U-shape when viewed from the rear of the cleaning chamber 3, and a connecting wall portion 38 connecting both lower ends of the curved wall portion 37. I have. Specifically, as shown in FIG. 4, the curved wall portion 37 includes an arc wall portion 60 formed in a semi-arc shape and straight wall portions extending downward from both lower ends of the arc wall portion 60, respectively. 61, 62, and the lower end of the straight wall portion 61 and the lower end of the straight wall portion 62 are connected by the connecting wall portion 38. In the connecting wall portion 38,
A second intake port 39 is formed, and in the intake air passage 28,
Air flows in from the second intake port 39 in addition to the first intake port 27 formed in the rear panel 5.

The fan motor 34 is arranged in a space surrounded by the partition peripheral wall 35 and below the communication port 36. The rotating shaft 40 of the fan motor 34 extends into the spiral casing 32, and the blower impeller 33 is mounted inside the spiral casing 32. Blast impeller 3
Reference numeral 3 denotes a rotary impeller having curved blades, which can push air taken in the direction of the rotary shaft 40 in the radial direction by the blades.

On the other hand, outside air can be taken into the intake air passage 28 located below the fan motor 34 from the first intake port 27 formed in the rear panel 5.
Therefore, the blower impeller 3 is
3 is rotated, the external air taken into the intake air passage 28 from the first intake port 27 and the air supplementarily taken in from the second intake port 39 are indicated by the outline arrows. After passing through the fan motor 34, it is sucked into the spiral casing 32 from the communication port 36. The air sucked into the spiral casing 32 is supplied to the blower impeller 3.
3, the air is sent out to the introduction air passage 29, and is blown out from the outlet 30 into the cleaning chamber 3.

As described above, the fan motor 34 is disposed in the intake air passage 28, and the air taken in from the first intake port 27 and the second intake port 39 is supplied to the fan motor 34.
Pass through. Therefore, the heat generated when driving the fan motor 34 is
Fan motor 3
There is no risk of abnormal heating of 4. Conversely, intake air path 2
The air flowing in the inside 8 is heated by removing the heat generated by the fan motor 34, so that the output of the heater 9 (see FIG. 2) disposed in the cleaning chamber 3 can be reduced. Therefore, the power consumption of the dishwasher 1 can be reduced.

Further, since the second air inlet 39 is formed in addition to the first air inlet 27, even if the first air inlet 27 is clogged with dust or the like, air can be sucked from the second air inlet 39. it can. Therefore, it is possible to eliminate the possibility that the fan motor 34 generates abnormal heat due to no intake. Further, even if the moisture contained in the air is condensed in the intake air passage 28, the condensed water flows from the second intake port 39 to the intake air passage 28.
Since the water is dropped outside, there is no possibility that the condensed water adversely affects the fan motor 34.

In this embodiment, the second intake port 39 is formed by cutting the connecting wall 38 into a comb-like shape. Thereby, the strength of the partition peripheral wall 35 can be increased as compared with a case where the connecting wall portion 38 is not provided or a case where a large opening is formed in the connecting wall portion 38. In addition, since the flow rate of the air taken into the intake air passage 28 from the second intake port 39 is increased, the fan motor 34 can be efficiently cooled.

Furthermore, since the fan motor 34 is located above the outlet 30 formed on the rear surface of the cleaning chamber 3, the water in the cleaning chamber 3 flows back through the introduction air passage 29 by any chance. However, water does not reach the fan motor 34. Referring to FIGS. 3 and 4 again, a first ventilation port 41 is formed in the rear panel 5 at a position facing the communication port 36. The first ventilation port 41 is provided mainly for the purpose of releasing the air in the intake air passage 28 to the outside when the blower fan 26 is stopped.

More specifically, since the washing and rinsing of the dishes is performed with warm water, the washing room 3 is filled with steam at the time of washing and rinsing. On the other hand, at the time of washing and rinsing, since the blower fan 26 is not driven, the steam filled in the washing chamber 3 may flow backward from the outlet 30 through the introduction air passage 29 and further flow into the intake air passage 28. Since the high-temperature and high-humidity air has an adverse effect on the fan motor 34 and the like, it is preferable that the steam flowing into the intake air passage 28 be released to the outside. Therefore, in this embodiment, the first ventilation port 41 is formed in the rear panel 5 so that the steam flowing from the cleaning chamber 3 into the intake air passage 28 can be released to the outside.

The reason why the first ventilation port 41 is provided at a position facing the communication port 36 is that the steam flowing from the introduction air path 29 into the intake air path 28 via the communication port 36 is immediately sent to the outside. This is for exhaust. Therefore, considering that the warm air flows upward, the first vent 41
Is not limited to the position facing the communication port 36,
What is necessary is just to be formed so that it may be located above.

The rear panel 5 further includes a first ventilation port 41.
A second ventilation port 42 is formed above. The second ventilation port 42 is mainly provided to allow air in a space sandwiched between the cleaning room 3 and the rear panel 5 to escape to the outside.
Therefore, it is possible to prevent the temperature in the space between the cleaning room 3 and the rear panel 5 from excessively rising. By the way, the drain pipe 24 connected to the second pump chamber 15 (see FIG. 1) of the pump device 13 extends toward the rear of the cleaning chamber 3, and is bent in an inverted U shape behind the cleaning chamber 3. And extending further out of the plane. Specifically, the drain pipe 24
Is bent upward at the rear part of the cleaning chamber 3, bent along the upper surface of the circular arc wall portion 60 of the partition peripheral wall 35 formed in the spiral casing 32, and extends downward. Therefore, since the water passing through the drain pipe 24 does not flow until it passes over the uppermost part of the drain pipe 24, there is no need to arrange a drain valve or the like in the middle of the drain pipe 24. Also, once the drain impeller 18 is rotated and the water in the drain pipe 24 once passes over the top of the drain pipe 24, it can be drained by a siphon action thereafter.

When the drainage pipe 24 is formed of a flexible straight pipe such as rubber, when hot water flows through the drainage pipe 24, the heat of the hot water softens the drainage pipe 24 and causes the inverted U.
There is a possibility that it will be bent at the character-shaped bent portion. However, in this embodiment, since the drain pipe 24 extends along the curved wall portion 37 (the arc wall portion 60) of the partition peripheral wall 35, the drain pipe 24 does not bend even if hot water is passed through the drain pipe 24. Also,
If the drainage pipe 24 is formed of a straight pipe, the drainage can be circulated more smoothly than a case where the drainage pipe 24 is formed of a bellows-shaped pipe.

Further, the heat of the hot water passing through the drain pipe 24 can be released to the outside from the second ventilation port 42 formed in the rear panel 5. Therefore, the space between the cleaning room 3 and the rear panel 5 does not become hot due to the heat of the hot water passing through the drain pipe 24. FIG. 5 is a rear view of the dishwasher 1, showing a state in which the rear panel 5 and the spiral casing 32 have been removed. The wind direction adjusting mechanism will be described with reference to FIG.

In this embodiment, the wind direction adjusting mechanism comprises:
It is provided in the introduction air passage 29, and includes a short rib 43 for distribution, a middle rib 44 for distribution, and a long rib 45 for distribution, which are provided upright on the rear surface of the cleaning chamber 3. 3 split ribs 4
3 to 45 extend substantially parallel to each other along the introduction air passage 29. The positions of the upper ends of the three dividing ribs 43 to 45 are
It is almost the same position. Three split ribs 43-4
5 have different lengths in the air flow direction, and are arranged so as to be longer in order from left to right in FIG. The longest diversion long rib 45 extends to the vicinity of the outlet 30.

When the blower impeller 33 is rotated clockwise in FIG. 5, air is sent from the intake air passage 28 (see FIG. 3) to the introduction air passage 29, and the air flows through the introduction air passage 29 to the outlet 30. Flow toward Then, the air flowing in the introduction air passage 29 is divided into four air passages by three dividing ribs on the way. That is, the spiral casing 32
(See FIG. 4), a first air passage 47 divided by a short rib 43 for diversion, a second air passage 48 divided by the short rib 43 for diversion and a middle rib 44 for diversion, and a middle rib for diversion. The air is diverted to a third air passage 49 defined by 44 and the long rib 45 for diversion, and to a fourth air passage 50 divided by the long rib 45 for diversion and the side surface of the spiral casing 32.

Of the divided air, the air flowing through the first air passage 47 and the air flowing through the second air passage 48 first merge below the short rib 43 for distribution. The distance between the side surface of the spiral casing 32 and the dividing rib 44 is determined by the first air passage 4.
7 is wider than the sum of the widths of the second air passage 48 and the width of the second air passage 48 by the thickness of the short rib 43, so that the flow velocity of the merged air is equal to the air flowing through the first air passage 47 and the second air passage. It is slower than the flow velocity of the air flowing through 48.

Next, the merged air and the air flowing through the third air passage 49 are merged below the dividing rib 44. For the same reason as described above, the flow velocity is also reduced when the air flowing through the third air passage 49 joins. Therefore,
The flow velocity of the air that merges from the first air path 47, the second air path 48, and the third air path 49 to the outlet 30 is lower than the flow velocity of the air that flows from the fourth air path 50 to the outlet 30. I have.
Therefore, the direction of the air blown from the outlet 30 is bent to the left in FIG. 5 by the force of the air from the fourth air passage 50.

Thus, as described above with reference to FIG. 2, the air blown out of the outlet 30 into the cleaning chamber 3
It is mainly blown to the heater 9 to be efficiently heated. Even without such a wind direction adjusting mechanism, it is conceivable that the air blown out from the air outlet 30 is blown to the heater 9 by forming the air outlet 30 immediately behind the heater 9. However, in this configuration, the outlet 30 is formed at a position extremely deviated toward the heater 9, and almost no air flows on the opposite side of the heater 9. As a result, drying unevenness of the tableware occurs, and this configuration is not preferable. In this embodiment, since the outlet 30 is formed slightly closer to the heater 9 than the center of the rear surface of the cleaning chamber 3, air is blown from the outlet 30 to the heater 9 by the above-described airflow direction adjusting mechanism. Since air is blown out to the opposite side of the heater 9,
There is no risk of drying unevenness.

FIG. 6 is an illustrative view showing another example of the structure of the wind direction adjusting mechanism, and its characteristic portion is shown. In the above-described wind direction adjusting mechanism, three split ribs 4
3 to 45 are provided, but in the wind direction adjusting mechanism shown in FIG. 6, one shift rib 51 is provided in the introduction air passage 29. Referring to FIG. 6, speed change rib 51 is formed to extend in a direction obliquely intersecting with the flow direction of air in introduction air passage 29, and the lower end thereof is located near air outlet 30. doing. Therefore, the inside of the introduction air passage 29 is divided into two air passages by the shifting ribs 51, and the air flowing through each air passage is joined at the outlet 30.

In FIG. 6, the air path on the left side of the shifting rib 51 is formed so that the downstream side gradually widens, and the air path on the right side of the shifting rib 51 is formed so that the downstream side gradually narrows. Have been. Accordingly, the flow velocity of the air flowing into the outlet 30 from the air path on the right side of the shifting rib 51 becomes faster than the flow velocity of the air flowing from the air path on the left side of the shifting rib 51 to the outlet 30. As a result, Outlet 3
Air is blown from 0 to the left side (the heater 9 side) in FIG.

In this configuration, the same operation and effect as those of the wind direction adjusting mechanism shown in FIG. 5 can be obtained. FIG.
FIG. 9 is an illustrative view showing still another example of the wind direction adjusting mechanism, and shows a characteristic portion thereof. In the above-described wind direction adjusting mechanism, the dividing ribs 43 to 45 or the shifting rib 51 are provided in the introduction wind path 29. However, in the wind direction adjusting mechanism shown in FIG. 7, the shape of the outlet is changed.

Referring to FIG. 7, the outlet 63 formed on the rear surface of the cleaning chamber 3 is formed so that the right side is narrower than the left side when viewed from the rear of the cleaning chamber 3.
That is, the outlet 63 is formed so that the side of the heater 9 (see FIG. 2) disposed in the cleaning chamber 3 is wide and the side opposite to the heater 9 is narrow. As a result, the flow rate of the air blown from the right side is higher than the flow rate of the air blown out from the left side of the blow-out port 63 in FIG. Air is blown toward.

Therefore, according to this configuration, the first
The same operation and effect as those of the second wind direction adjusting mechanism can be obtained. FIG. 8 shows the spiral casing 32 and the outlet 30.
FIG. 5 is an enlarged perspective view showing a connection portion with the cleaning chamber 3 when viewed from the inside of the cleaning chamber 3. First, referring to FIG.
At the lower end of the spiral casing 32, a fitting groove 55 opened toward the cleaning chamber 3 is formed so as to extend substantially horizontally along the lower edge of the spiral casing 32. A bar-shaped elastic packing 56 extending horizontally is fitted in the fitting groove 55.

Referring to FIGS. 3 and 8, as described above, the outlet 30 is formed in a horizontally long rectangular shape including a lower side, left and right sides, and an upper side when viewed from the front. On the lower side, a first flange portion 52 for contact extends toward the rear of the cleaning chamber 3 (the rear side in FIG. 8). The leading edge of the first flange portion 52 is in contact with the lower edge of the spiral casing 32. The inner surface of the spiral casing 32 and the upper surface of the first flange portion 52 are substantially flush with each other, and the air flowing through the introduction air passage 29 receives the air from the outlet 3.
It is designed to exhaust smoothly from zero.

A second flange 53 is formed below the first flange 52 from the rear surface of the cleaning chamber 3 toward the rear. The second flange portion 53 is fitted in the fitting groove 55, and the leading edge thereof is in contact with the elastic packing 56. Therefore, water does not leak from between the spiral casing 32 and the outlet 30. Further, the vicinity of the center of the first flange portion 52 is cut out, and the second
The rear surface of the cleaning chamber 3 is cut out to the upper surface of the flange portion 53 to form a water return portion 54. This return section 54
It is formed to return the water that has entered downward from the gap between the first flange portion 52 and the lower end edge of the spiral casing 32 to the cleaning chamber 3.

More specifically, water spouted from the arm 8 (see FIG. 1) during washing and rinsing is applied to the washing chamber 3
Since the light is reflected in various directions by the inner surface and the tableware (see FIG. 1), it may enter the introduction air passage 29 from the outlet 30. As shown by the black arrows in FIG. 8, most of the water that has entered the introduction air passage 29 is first discharged from the inner surface of the spiral casing 32.
Although it flows to the upper surface of the flange portion 52 and returns to the inside of the cleaning chamber 3, a part thereof invades downward from a gap between the first flange portion 52 and the lower edge of the spiral casing 32. Then, since the leading edge of the second flange portion 53 is in contact with the elastic packing 56, there is a possibility that water that has entered through the gap may accumulate on the second flange portion 53. In particular, water containing dirt reflected on the tableware and adhered to the tableware is the second.
If it accumulates on the flange portion 53, an unpleasant odor may be generated.

Therefore, in this embodiment, the return section 5
4 is formed, and water that has penetrated downward from a gap between the first flange portion 52 and the lower end edge of the spiral casing 32 is returned to the cleaning chamber 3 from the return portion 54. Thus, the above-described problem does not occur. Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the case where the drying device according to the present invention is applied to a dishwasher has been described as an example.
In addition to the dishwasher, the present invention is also applicable to a dish dryer having only a function of drying dishes and a clothes dryer for drying clothes after washing.

In addition, various changes can be made within the scope described in the claims.

[0052]

According to the first to third aspects of the present invention, the air blown out of the outlet into the housing chamber by the airflow direction adjusting mechanism is mainly blown to the heater. Thereby, the air sent into the accommodation room is efficiently heated by the heater. According to the invention described in claim 4,
Water does not leak from between the introduction wind path and the outlet.

According to the fifth aspect of the present invention, it is possible to prevent the generation of unpleasant odor due to the accumulation of dirt-containing water on the tableware on the second flange portion.
