The door portion 9 includes a comprehensive decorative plate 9a provided on the front surface of the washing tank 2 and a handle 9b provided on the decorative plate 9a and used to pull the washing tank 2 out. The door portion 9 is fixed to the washing tank 2 through the support portion 9c. Thereby, the door part 9 moves with the washing tank 2. The decorative plate 9a is made of the same material and the same material as the door sheet or drawer of the system kitchen K in which the dishwasher is stored, and is installed on the entire front surface of the door 9. Furthermore, the handle 9b is used when a user pulls the washing tank 2 out of the casing 1 and grasps it or catches his fingers. Moreover, the handle 9b is also composed of the same material and the same material as the door or drawer of the system kitchen K.

However, in the door part of the conventional dishwasher, most of the comprehensive door part will be equipped with the same decorative plate as the system kitchen door sheet, but in general, the style of the handle will be different. Specifically, as described above, the unlocking operation lever is built into the conventional door portion. Furthermore, an operation switch, a running light, etc. are arrange | positioned in a door part.

However, the dishwasher of this embodiment is not provided with an operation lever, an operation switch, a running light, or the like in the door portion. Therefore, the overall pattern of the door portion 9 and the same pattern as the system kitchen K can be configured including the handle 9b. As a result, the dishwasher was not easily recognized at first glance, and the dishwasher was housed in the system kitchen, thereby realizing a dishwasher having a structure with excellent uniformity.

Moreover, the middle cover 10 is provided in the upper part of the inside of the casing 1, and closes the opening on the upper surface of the washing tank 2. The middle cover 10 is provided with a cushion material 10 a on a surface facing the opening of the washing tank 2, and is arranged to freely move up and down by a link mechanism 10 b including a pair of front and rear links. In addition, the middle cover 10 moves up and down through the link mechanism 10b in response to the movement in the front and rear directions of the cleaning tank 2. For example, when the cleaning tank 2 is fully pushed into the inside of the casing 1, the upper surface of the cleaning tank 2 The opening is blocked.

The control device 11 is disposed between the washing tank 2 and the door 9 and controls and executes a series of washing operations such as a washing step, a flushing step, and a drying step of the dishwasher.

The operation unit 12 is provided above the control device 11 so that the user can perform a series of operation settings and the like.

The first air supply device 13 constituting the air supply device is provided outside the bottom surface of the washing tank 2, and blows outside air into the washing tank 2. At this time, the first delivery The wind device 13 supplies external air into the washing tank 2 through a ventilation hole 14 provided at a lower portion of the front surface of the washing tank 2. Then, the air supplied to the cleaning tank 2 is discharged to the exhaust path 16 through a discharge hole 15 provided in the upper part of the front surface of the cleaning tank 2.

In addition, the exhaust path 16 is formed in a U-shape in which a buckling portion is disposed below in a front-rear direction, and is disposed between the door portion 9 and the washing tank 2. At this time, one end of the exhaust path 16 communicates with a discharge hole 15 provided in the washing tank 2. On the other hand, the other end of the exhaust path 16 has an exhaust port 17 provided so as to be in contact with the upper end surface 9 d of the decorative plate 9 a of the door portion 9. Then, the air in the washing tank 2 is exhausted through the exhaust port 17 of the exhaust path 16.

In addition, as shown in FIG. 1, the ventilation path 18 is provided in front of the exhaust path 16 (between the door portion 9), and at least a portion thereof is in surface contact with the exhaust path 16. In addition, one end of the air supply path 18 is arranged to merge with the exhaust path 16 before reaching the exhaust port 17. On the other hand, the other end of the air blowing path 18 is provided so as to communicate with the second air blowing device 19. As a result, the air exhausted from the cleaning tank 2 by the first air supply device 13 through the exhaust holes 15 and the exhaust path 16 and the air outside the cleaning tank 2 aired by the second air supply device 19 are in the air supply path. One of 18 is mixed side by side. Moreover, the mixed air is discharged from the exhaust port 17 of the exhaust path 16 to the outside of the dishwasher machine.

Hereinafter, the structure of the exhaust port 17 of the dishwasher of this embodiment is demonstrated in detail.

As shown in FIGS. 1 to 3, the exhaust port 17 is provided at least rearward (at the side of the washing tank 2) from the front surface of the decorative plate 9 a and abuts along the outer side of the upper end surface 9 d of the decorative plate 9 a. Furthermore, the exhaust port 17 in the exhaust path 16 provided between the decorative plate 9a provided in the door portion 9 and the kitchen fluid table 20 is configured to remove the The air is exhausted forward. Thereby, on the front surface of all the door portions 9, a decorative plate 9a of the same style as the door panel or drawer of the system kitchen K to be accommodated can be installed. As a result, the design of the system kitchen K will be improved.

As shown in FIG. 2, the exhaust path 16 facing the exhaust port 17 near the exhaust port 17 and at the upper portion of the decorative plate 9 a has a lateral direction (a direction orthogonal to the front-rear direction) shown in FIG. 3. The portion of the long lower surface 16d is formed by the upper end surface 9d of the decorative plate 9a. That is, the wall surface that was originally the long surface 16d of the lower portion of the exhaust path 16 is constituted by the upper end surface 9d of the decorative plate 9a. Thereby, the wall surface of the long surface 16d of the lower part of the exhaust path 16 can be omitted.

That is, as shown in FIG. 3, the upper long surface 16 a which is longer in the lateral direction, and the left and right short surfaces 16 b which are shorter in the vertical direction (vertical direction) and other parts of the exhaust path 16 formed by the exhaust hole 15 The wall surface is molded in one piece. In addition, the lower end 16b1 of the left and right short surfaces 16b and the end surface 9d of the upper portion of the decorative plate 9a directly contact each other. Thereby, for example, an elongated rectangular exhaust port 17 can be formed by using three wall surfaces formed by the upper long surface 16a and the left and right short surfaces 16b of the exhaust path 16 and the upper end surface 9d of the decorative plate 9a. At this time, a rib 16c may be provided on the long surface 16a of the upper portion of the appropriate position constituting the exhaust port 17, at least at one point parallel to the short surface 16b, and in contact with the end surface 9d of the upper portion of the decorative plate 9a . Thereby, when the lower end 16b1 of the left and right short surfaces 16b1 and the lower end 16c1 of the rib portion 16c are fixed to the supporting portion 9c, the decorative plate 9a abuts against the upper end surface 9d of the decorative plate 9a. As a result, the short surface 16b and the rib 16c near the exhaust port 17 of the exhaust path 16 can be used to restrict the mounting position in the upper direction of the decorative panel 9a, thereby preventing positional displacement.

The temperature sensor 21 is provided outside the bottom surface of the washing tank 2. And The temperature sensor 21 can detect the ambient temperature immediately after the washing tank 2 is operated without washing water. In addition, the temperature sensor 21 detects the temperature of the washing water in the washing step and the flushing step after the washing water is supplied. Furthermore, in the drying step, the temperature sensor 21 detects the temperature of the air in the washing tank 2. In addition, the control device 11 controls a washing step, a flushing step, and a drying step according to a temperature signal detected by the temperature sensor 21 to perform a washing operation.

The control device 11 controls the operation time of the first air supply device 13 and the second air supply device 19.

That is, in the drying step, the control device 11 controls the combination of the operation time of the first air supply device 13 and the second air supply device 19 based on the ambient temperature detected immediately after the start of the operation. Specifically, the mixing ratio of the high-temperature and high-humidity air discharged from the cleaning tank 2 through the exhaust path 16 and the external air supplied through the ventilation path 18 is adjusted. This reduces the temperature and humidity of the air discharged from the exhaust port 17. As a result, it is possible to prevent dew condensation around the dishwasher and the like, and to suppress unpleasantness of the user.

Hereinafter, a specific operation and effect of adjusting the temperature and humidity of the air discharged from the exhaust port 17 by the control device 11 will be described.

Generally, at the beginning of the drying step, high-temperature and high-humidity air, which contains a large amount of water, heated by the heater 8 is discharged from the discharge hole 15 of the washing tank 2. At this time, when the high-temperature and high-humidity air is directly discharged from the exhaust port 17 through the exhaust path 16, it will concentrate on the gap between the decorative plate 9a and the kitchen fluidizer 20. Therefore, high-temperature and high-humidity air becomes susceptible to condensation around the exhaust port 17. Therefore, in order to prevent dew condensation, the control device 11 intermittently operates the first blower device 13 that discharges high-temperature and high-humidity air toward the exhaust path 16. Reduce air volume. Further, the control device 11 continuously operates the second air blowing device 19 to increase the amount of air in the air outside the washing tank 2 supplied to the air blowing path 18. That is, the amount of air mixed with high-temperature and high-humidity air is increased. This reduces the temperature and humidity of the air discharged from the exhaust port 17. As a result, the occurrence of dew condensation around the exhaust port 17 can be prevented. In addition, as a method of changing the air volume of an individual air supply device, for example, the time for intermittent operation can be adjusted, and the number of rotations for continuous operation can be adjusted.

At this time, when the ambient temperature of the dishwasher detected by the temperature sensor 21 is low, usually, because the surface temperature of the decorative plate 9a or the kitchen fluid table 20 is also low, the dew point temperature is low and condensation is easy to occur produce. At this time, the control device 11 is changed to reduce the operation time of the intermittent operation of the first blower device 13 and reduces the discharge amount of high-temperature and high-humidity air from the washing tank 2. Thereby, the ratio of the discharge amount of the high-temperature and high-humidity air to the air volume of the air supplied from the outside of the washing tank 2 by the second air supply device 19 is reduced. At the same time, in order to maintain the drying performance, the control device 11 extends the operation time of the drying step.

That is, the control device 11 first uses the temperature sensor 21 to detect the ambient temperature at the start of operation to estimate the surface temperature of the decorative plate 9a or the kitchen fluidizer 20. At this time, when the detected ambient temperature is high, the operation of the first air supply device 13 is not suppressed, and dew condensation to the surroundings can be prevented, and the drying step can be performed efficiently for a short time. On the other hand, when the detected ambient temperature is low, the time of the drying step is prolonged, and the dew condensation in the surrounding area is suppressed in advance. Thereby, the most suitable drying operation according to the ambient temperature can be performed.

As described above, the tableware washing opportunity of this embodiment is adjusted from The temperature and humidity of the air discharged from the exhaust port 17.

The operation and effect of the dishwasher configured as described above will be described below.

First, the user grasps the handle 9b provided on the door portion 9 and pulls the washing tank 2 out of the casing 1. Next, the dirty tableware 4 is placed in the tableware basket 5 arrange | positioned in the washing tank 2, and a lotion is put. After that, the user selects an operation program using a program selection button located in the operation section 12, and depresses the operation start button.

Then, the washing tank 2 is pushed into the storage position in the casing 1. At this time, the middle cover 10 is moved backward and downward by the link mechanism 10b, and the opening of the washing tank 2 is closed. At the same time, a micro switch (not shown) is used to detect the situation where the cleaning tank 2 is located in the storage position that is completely pushed in. And, the detection signal detected by the micro switch is sent to the control device 11. As a result, the control device 11 starts the washing operation of the dishwasher.

Next, when the washing operation is started, the control device 11 opens a water supply valve (not shown), and supplies tap water serving as washing water into the washing tank 2. Furthermore, the control device 11 is energized with the heater 8 arranged in the washing tank 2 to heat the washing water, and controls the washing pump 6 a to press the washing water toward the washing nozzle 7. The pressurized washing water is sprayed from the washing nozzle 7 toward the dishes 4. Thereby, the washing process which makes the dirt of the tableware 4 fall off is performed for a predetermined time, and it moves to a flushing process.

Next, in the flushing step, the washing water is replaced several times to perform flushing for a predetermined time. After that, the newly supplied washing water is heated to about 80 ° C. and flushed with a heater 8 for heating and flushing for a predetermined time. Water steps.

Next, after the heating and flushing step is completed, the control device 11 discharges the washing water from the washing tank 2. In addition, the control device 11 heats the air in the washing tank 2 with a heater 8 and uses the first air supply device 13 to exhaust high-temperature air containing a large amount of moisture from the exhaust hole 15 through the exhaust port 17 of the exhaust path 16 to the outside . Thereby, the drying process which dries the inside of the tableware 4 and the washing tank 2 is performed. After that, the control device 11 stops the operation of the dishwasher when a predetermined time elapses or reaches a predetermined temperature in the washing tank 2, and ends.

As described above, the operation of the dishwasher of this embodiment is executed.

The effects of the dishwasher of this embodiment will be described below.

Generally, when the dishwasher is installed in the system kitchen K, the gap between the kitchen fluidizer 20 and the upper end of the door 9 is, for example, narrow, about several millimeters. Therefore, when the exhaust path 16 and the exhaust port 17 are provided in a narrow gap, and the dried air and the like are discharged to the outside of the machine, the height dimension of the exhaust port 17 must be made smaller. At this time, when the upper surface 16 a of the upper part of the exhaust path 16 and the lower end surface 16 d formed by the upper end surface 9 d of the decorative plate 9 a opposite to the upper main surface 16 a are used individually, the exhaust port 17 is formed in the gap In this case, the height dimension of the exhaust port 17 becomes smaller. Therefore, there is a possibility that the air in the cleaning tank 2 cannot be exhausted sufficiently, and the drying performance may be lowered.

Therefore, the dishwashing mechanism according to the present embodiment is a portion corresponding to the long surface 16d of the lower portion of the exhaust path 16 by using the upper end surface 9d of the decorative plate 9a as both. Thereby, the exhaust path 16 and the exhaust gas can be ensured in a narrow gap. The opening area of the port 17 is maximized. As a result, the air volume required for drying can be ensured, and deterioration in drying performance can be prevented.

Moreover, according to this embodiment, the exhaust port 17 is arrange | positioned behind the front surface of the upper end surface 9d of the decoration board 9a. Therefore, in a state where the dishwasher is stored in the system kitchen K, it is difficult to see the exhaust port 17 from the viewpoint of the user. In particular, when a user stands near the kitchen counter 20, it is even harder to see. Thereby, the pattern of the door portion 9 can be matched with the pattern of other door plates and the like of the system kitchen K. As a result, it is possible to realize a dishwasher capable of suppressing a reduction in the design of the system kitchen K to be stored.

In addition, in general, the decorative panel 9a mounted on the door portion 9 can be adjusted slightly in cooperation with the upper and lower positions of the door K or the drawer of the system kitchen adjacent to the door portion 9. At this time, when the decorative panel 9a is attached in an offset manner, there is a possibility that the exhaust port 17 may be blocked and the discharge may be blocked. However, according to this embodiment, the upper end surface 9d of the decorative plate 9a contacts the lower end 16b1 of the short surface 16b near the exhaust port 17 constituting the exhaust path 16 and the lower end 16c1 of the rib 16c, and restricts the upward mounting position. Therefore, the use of the decorative plate 9 a does not hinder the discharge from the exhaust port 17. Furthermore, when fixing the decorative plate 9a toward the support portion 9c of the door portion 9, the decorative plate 9a can be positioned by matching the lower end 16b1 of the short surface 16b and the lower end 16c1 of the rib portion 16c. Therefore, workability such as installation of the decorative plate 9a is improved.

In addition, in the present embodiment, when the decorative plate 9a of the door portion 9 is mounted on the support portion 9c, a configuration in which the vertical position of the decorative plate 9a relative to the door piece or drawer of the system kitchen K is slightly adjusted may be provided. Specifically, the exhaust port 17 provided in the gap may be configured to expand and contract longitudinally to the exhaust path 16 within a range that does not hinder the access of the washing tank 2. Furthermore, it can also be constructed in a fixed row In the state of the position of the exhaust port 17 of the air path 16, the fine adjustment is performed by the expansion and contraction of the foot 22 provided under the casing 1 shown in FIG. This makes it possible to securely attach the decorative plate 9 a at an appropriate position regardless of the dimensional accuracy of the constituent members and the like. As a result, a dishwasher excellent in workability and productivity can be provided.

However, in the present embodiment, the configuration in which the exhaust port 17 is provided on the end surface 9d of the upper portion of the decorative plate 9a and is arranged in the gap between the decorative plate 9a and the kitchen fluidizer 20 is described as an example, but it is not limited thereto. For example, the exhaust port 17 may be provided along the outer side of any one of the left and right end surfaces of the decorative panel 9a, and may be disposed in a gap between the decorative panel 9a and the door panel of the system kitchen K. Furthermore, it is good also as a structure provided in the end surface of the lower part of the decorative board 9a. At this time, similarly to the above-mentioned embodiment, it is preferable that the installation position of the decorative plate 9a is restricted by the exhaust port 17 for each direction provided.

In this embodiment, the configuration of the upper end surface 9d of the decorative plate 9a and the long surface 16d of the lower portion of the exhaust path 16 near the exhaust port 17 is used as an example, but it is not limited to this. For example, when it is possible to obtain the opening area of the exhaust port 17 that is not obstructed for discharging, it is not necessary to use both the upper end surface 9d and the like of the decorative plate 9a. That is, the entire surface of the surrounding wall surface forming the exhaust path 16 may be formed by individual members, and the exhaust port 17 may be formed.

In the present embodiment, the cross-sectional shape of the exhaust path 16 or the opening shape of the exhaust port 17 is described as an example, but it is not limited thereto. For example, it may be a combination of rectangular shapes or a shape having a curved surface portion. As a result, the freedom of design will be improved, and the design will be further improved.

In addition, in the present embodiment, the first The configuration of the blower device 13 and the second blower device 19 that merges the air outside the cleaning tank 2 on the way of the exhaust path 16 is described as an example, but it is not limited to this. For example, it is good also as a structure which does not provide the 2nd ventilation device 19. At this time, instead, the air supply from the first air supply device 13 is divided into a flow path flowing into the washing tank 2 and a non-flowing air flow path 18, and for example, a flow distribution device (not shown) is provided. Accordingly, the air flowing into the cleaning tank 2 and discharged from the air supply path 18 can be configured to merge with each other on the way of the exhaust path 16. At this time, the control device 11 is preferably controlled in such a manner that the ratio of the air volume from the washing tank 2 to the air volume from outside the washing tank 2 is adjusted by a shunting device. Thereby, the same effect as that of the configuration of two air blowing devices can be achieved with one air blowing device.

As described above, the dishwasher of the present invention includes a cabinet with an open front surface, a washing tank provided in the cabinet so as to be freely accessible, a front of the washing tank, and covering when the washing tank is housed in the cabinet The door on the front surface of the cabinet, a washing device for washing tableware stored in the washing tank, a blower for exhausting the air in the washing tank to the exhaust path, and a series of controls to perform a washing operation Device. In addition, the door portion includes a decorative plate provided in front of the washing tank, and a handle provided on the front surface of the decorative plate to pull out the washing tank, and the exhaust path includes exhausting the air in the washing tank forward and along the An exhaust port provided on the outside of the end face of the decorative plate.

With this configuration, a decorative plate having the same specifications as the door plates or drawers of the housed system kitchen is attached to the front surfaces of all the door portions. As a result, the design of the system kitchen can be improved.

In addition, the dishwasher of the present invention may have an exhaust port configured to restrict the installation position of the decorative plate. Thereby, the exhaust port can be prevented from being decorated by the panel Occlusion and obstruction. As a result, the opening area of the exhaust port can be secured. Furthermore, when fixing the decorative plate, it can be positioned using an exhaust port. As a result, the workability of installing the decorative board is improved.

In addition, the exhaust path of the dishwasher of the present invention is configured to be retractable and to slightly adjust the installation position of the decorative plate restricted by the exhaust port. Thereby, the position of the decorative plate of the system kitchen can be easily adjusted in accordance with the position of the door or drawer of the system kitchen adjacent to the door of the dishwasher.

In addition, the dishwasher of the present invention can be constructed by using the end surface of the decorative plate as a part of the exhaust path wall surface near the exhaust port and the exhaust port. This can ensure that the opening area of the exhaust port and the exhaust path is maximized. As a result, the air volume required for exhaustion can be sufficiently ensured, and deterioration in drying performance can be prevented.

In the dishwasher of the present invention, the exhaust port can be arranged further behind than the front surface of the decorative plate. With this, when the dishwasher is stored in the system kitchen, the exhaust port can be hardly seen from the user's perspective. In particular, it is harder for users to stand near the kitchen counter. Therefore, the pattern of the door can be easily matched with the pattern of the system kitchen door and the like. As a result, it is possible to provide a design dishwasher that does not damage the stored system kitchen.

Moreover, the dishwasher of this invention may have a ventilation path which merges the air outside a washing tank in the middle of an exhaust path. Thereby, the temperature and humidity of the air discharged from the exhaust port can be reduced by mixing the air outside the cleaning tank with the high temperature and high humidity air from the cleaning tank. As a result, it is possible to prevent dew condensation toward the periphery of the system kitchen and to suppress user discomfort.

In addition, the dishwasher of the present invention may have a temperature sensor that detects the ambient temperature. When the ambient temperature is low, the control device is controlled relative to the supply from the exhaust path at least in the initial stage of the drying step of the washing operation. The air volume of the air outside the cleaning tank makes the ratio of the air volume of the air from the cleaning tank smaller. Therefore, when the temperature corresponding to the dew point around the surroundings is low, the air inside and outside the washing tank can be properly mixed to reduce the temperature and humidity of the exhaust air. As a result, it is possible to effectively suppress the occurrence of dew condensation even in a situation where dew condensation is likely to occur, and to perform a more appropriate drying operation in accordance with the ambient temperature.

In addition, the dishwasher of the present invention can also have retractable feet in the casing and can slightly adjust the installation position of the decorative plate restricted by the exhaust port. Thereby, in accordance with the position of the door or drawer of the system kitchen adjacent to the door of the dishwasher, the position of the decorative plate can be adjusted slightly.
