Description

  The present invention relates to a dishwasher, and more particularly to prevention of condensation at an exhaust port and noise reduction.

  In the conventional dishwasher, in the washing and rinsing process, the washing water stored in the washing tank installed in the main body is heated by a water heater, pressure is given by a washing pump, and the nozzle is used. Sprinkles on tableware stored in the tableware basket.

  In this cleaning and rinsing process, high-temperature humid air leaking from the exhaust port causes condensation around the exhaust port, causing discoloration of the equipment, deterioration of the material of the sink countertop, and dripping condensation on the kitchen. There were problems such as imposing extra effort such as cleaning up on the user due to stains on the floor.

Thus, improvements have been made such as installing an on-off valve in an exhaust duct connecting the exhaust port and the cleaning tank (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 4-135264

  However, in the conventional dishwasher described in Patent Document 1, since the sealing structure of the on-off valve (shutter) is ambiguous, high-temperature humid air leaks out from the exhaust port in the cleaning and rinsing process, or suddenly due to the outside air. In some cases, it was cooled down to form water droplets and adhered to the exhaust port, which wetted the user's clothing. In addition, water droplets caused rusting of the equipment.

  The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a dishwasher that prevents high-temperature humid air from being discharged from an exhaust port during a washing and rinsing process. Objective.

The dishwasher according to the present invention is
A washing tank constituting a container for washing and drying tableware;
A heating element for heating the washing water;
A cleaning pump for pressurizing the cleaning water;
A nozzle for injecting pressurized washing water into the washing tank;
A cleaning tank exhaust port for discharging hot humid air generated in the cleaning tank;
An external exhaust port communicating with the cleaning tank exhaust port and discharging hot humid air generated inside the cleaning tank to the outside of the device;
An exhaust duct disposed between the cleaning tank exhaust port and an external exhaust port;
A shutter formed in the exhaust duct so as to be freely opened and closed;
And a guide body formed integrally with the outer wall of the cleaning tank in the exhaust duct and abutting on the surface of the shutter on the cleaning tank side.

  According to the dishwasher according to the present invention, the guide body formed on the outer wall of the cleaning tank in the exhaust duct is in contact with the shutter, thereby obtaining a high sealing function. Further, since the guide body is provided integrally with the cleaning tank, it is not necessary to provide a seal member between the guide body and the cleaning tank, and thus the structure can be simplified. .

Embodiment 1 FIG.
1 is a longitudinal sectional view of a dishwasher according to Embodiment 1 of the present invention, FIG. 2 is a front view of the dishwasher, and FIG. 3 is a state in which the door of the dishwasher is pulled forward. FIG. 4 is a longitudinal sectional view of the main part of the exhaust unit of the first embodiment, FIG. 5A is a perspective view of the main part of an example of the exhaust unit of the first embodiment, and FIG. These are the principal part perspective views of the other example of the exhaust unit of Embodiment 1. FIG.

  As shown in FIG. 1, the dishwasher 1 has an opening 2 a in the front, is disposed inside the casing 2, which corresponds to the outer shell, and inside the casing 2, and has an opening 3 f formed in the upper part. A cleaning tank 3 constituting a container for cleaning and drying the container, a lid (opening / closing lid) 4 for closing the opening 3f of the cleaning tank 3 and a front part of the cleaning tank 3 It is a device composed of a door (door) 5 that opens and closes the opening 2a of the housing 2 and many other functional parts. A link mechanism 4a is attached to the lid body 4. The link mechanism 4a opens and closes the opening 3f of the cleaning tank 3 by moving the lid body 4 in the vertical direction. As shown in FIG. 2, the door 5 includes an operation unit 7 (including an operation switch 8), and the door 5 and the cleaning tank 3 are connected to each other. It is slidably supported with respect to the bottom of the body 2. For this reason, by pulling out the door 5, the washing tank 3 is pulled out as shown in FIG. Thereby, the tableware 91 can be taken in and out.

  Further, as shown in FIG. 1, a tank blowing port 3 a for supplying hot air necessary for drying the dishes 91 is formed behind the cleaning tank 3 that plays a central role in the dishwasher 1. Outside, a drying unit 21 for generating warm air is attached. The drying unit 21 includes a drying blower 22 for supplying air, a drying heater 23 for heating the air, and a casing 24 in which they are built. The casing 24 is provided with an opening 24a for the drying blower 22 to suck in air.

  Further, a tank exhaust port (water tank exhaust port) 3b for discharging high-temperature wet air generated inside the cleaning tank 3 is provided in front of the cleaning tank 3, and the high-temperature wet air is provided above the door 5 in the device. An external exhaust port 5a for discharging to the outside is formed, and an exhaust unit 41 for connecting them is attached between them. As shown in FIG. 4, the exhaust unit 41 includes a shutter 43 and an exhaust duct 44 incorporating the shutter 43, and includes an eave surface A44a, an inclined surface 44b, and an eave surface B44c. Thus, the labyrinth structure is formed so that the cleaning water sprayed from the nozzle 14 in the cleaning tank 3 is not easily scattered from the external exhaust port 5a (however, the eave surface A44a is integrated with the outer wall of the cleaning tank 3). Is formed.) In addition, each surface of the exhaust duct 44 is configured so that all surfaces are inclined downward so that the condensed water can be easily returned to the cleaning tank 3. It is returned to the cleaning tank 3 from the lowermost tank exhaust port 3b that is transmitted and collected. Note that both ends of the exhaust unit 41 are attached to the inner wall side of the external exhaust port 5a and the outer wall of the cleaning tank 3, respectively, and for the attachment, for example, a packing 50 is interposed to form an airtight structure.

  In addition, a guide body (tank seal rib) 3c for rectifying the flow of air in the exhaust duct 44 is formed on the outer wall of the cleaning tank 3 in order to eliminate high temperature wet air leakage to the upper gap of the shutter 43. A tank seal surface 3d is formed on the tip surface of the guide body (tank seal rib) 3c so as to be in close contact with the surface of the shutter 43 on the cleaning tank side without any gap. Yes. In the example of FIG. 5A, the shape of the guide body (tank seal rib) 3c is substantially U-shaped, but the guide body (tank seal rib) 3c has, for example, a substantially U-shape as shown in FIG. If the lower side of the four sides of the rib is open and the tip end surface is in close contact with the shutter 43 without any gap, there is no functional problem. Further, a sealing member (not shown) such as rubber packing may be provided on the tank sealing surface 3d. In such a case, the sealing performance is further improved, and it is possible to more reliably prevent leakage of high-temperature humid air generated in the cleaning tank 3. The same applies to the embodiments described later. This sealing member may be provided not on the tank seal surface 3d side but on the surface of the shutter 43 on the cleaning tank 3 side.

  Further, in order to prevent the condensed water or the like due to the above action from stagnation in the exhaust duct 44, the inner wall eave surface A44a, the inclined surface 44b, and the eave surface B44c are inclined, for example, the shutter 43 is also inclined. The inside of the exhaust duct 44 can be kept hygienic without condensate water being stagnated. The above-mentioned inner wall eave surface A44a corresponds to a bypass wall of the present invention. By providing such an inner wall eave surface A44a in the exhaust duct 44, air from the tank exhaust port 3b to the external exhaust port 5a is provided. It is possible to lengthen the air path, and during the drying process, the high-temperature humid air generated in the cleaning tank 3 is reduced in humidity to make water vapor into water droplets and returned to the cleaning tank 3, and the external exhaust port 5a. It becomes possible to lower the temperature of the exhaust from the engine. Further, the inner wall eave surface A44a is formed integrally with the outer wall of the cleaning tank 3, whereby the structure of the exhaust unit 41 (exhaust duct 44) is simplified. Further, a step 44f for receiving the lower side of the shutter 43 is formed on the inclined surface 44b, and when the step 44f contacts the lower side of the shutter 43, the sealing performance of the shutter 43 is further improved.

  6 (A) and 6 (B) are views with the exhaust unit 41 of FIG. 1 removed, (A) is a perspective view as seen from the external exhaust port 5c side, and (B) is as seen from the cleaning tank 3 side. FIG. When the exhaust unit 41 is attached, the inner wall eave surface A44a is inserted into the lower space 44g, and the guide body 3c is inserted into the upper space 44h. In the cleaning and rinsing process, the shutter 43 whose one end is rotatably supported by the exhaust unit 41 abuts on the guide body 3c, and the hot and humid air in the cleaning tank 3 is not discharged from the external exhaust port 5a. It is like that. The exhaust duct 44 is made of a material having better heat dissipation than the cleaning tank 3, for example, a metal material. For this reason, the cooling performance of the high-temperature humid air passing through the exhaust duct 44 is improved, and the external duct This is useful for lowering the temperature of the air exhausted from the exhaust port 5a.

Next, the operation in the case of cleaning and drying dishes with the dishwasher according to the first embodiment will be described.
First, as shown in FIG. 3, the door 5 is pulled to the labor side, the tableware 91 to be cleaned and dried is stored in the tableware basket 6, an appropriate amount of detergent is put in the vicinity thereof, and the door 5 is closed.
Next, the operation switch 8 provided in the operation unit 7 is pressed to start the operation of the device. The operation is controlled by the control device 9, and each functional component is operated in accordance with the command, and the cleaning process, the rinsing process, the heating rinsing process, and the drying process are performed in this order.

  When the cleaning process is started, first, the water supply valve 10 is opened to supply water into the cleaning tank 3. At this time, the water level in the cleaning tank 3 is monitored by the water level detection device 11, and when it is detected that the water level has reached a predetermined level, the water supply valve 10 is closed. Next, the hot water heater 12 is energized to heat the stored washing water, and the washing pump 13 is energized to apply pressure to the washing water, and the nozzle 14 is used to spray the dishes 91. The cleaning is performed while circulating the stored cleaning water. The cleaning water that has dropped to the bottom of the cleaning tank 3 is collected, pressure is applied again by the cleaning pump 13, and the nozzle 14 is used to spray the cleaning water 91. It repeats that. Further, the cleaning water temperature is monitored by the water temperature detecting element 15, and when detecting that the temperature has reached a predetermined temperature, energization of the water heater 12 is stopped.

  When the cleaning process is started and a predetermined time elapses, energization of the water heater 12 and the cleaning pump 13 is stopped, and the drainage pump 16 is energized to drain the cleaning water stored in the cleaning tank 3 to the outside. Thereby, the cleaning process is completed.

Here, the operation of the exhaust unit 41 and the effect thereof will be described.
The shutter 43 is attached to a bearing 44d (see FIG. 4) formed in the exhaust duct 44, and is normally closed by the action of its own weight. The exhaust duct is generated by a sealing action with the tank seal surface 3d of the guide body 3c integrally formed on the outer wall side of the cleaning tank 3 so that the injection sound of the cleaning water generated in the rinsing process is not leaked from the external exhaust port 5a. 44 has the function of blocking. However, at the time of a drying process, it opens by the force of the warm air which generate | occur | produces from the drying unit 21, and is comprised so that smooth exhaustion may be performed.

  The washing is performed while heating the washing water by the water heater 12, and the washing water temperature is usually set to a temperature at which the ability of the detergent can be maximized, and is set to about 60 ° C. Therefore, the air inside the cleaning tank 3 is in a high temperature and humid state filled with a lot of steam, and further, due to the expansion of air due to heating and the action of the upward airflow, the high temperature humid air passes through the tank exhaust port 3b and becomes the exhaust port. It tries to leak from 5a.

  Since the exhaust duct 44 can be shut off by the sealing action described earlier and the exhaust of the high temperature humid air can be shut off, the high temperature humid air is not discharged from the external exhaust port 5a, and the periphery of the exhaust port is condensed. There is no. In addition, since the splashing sound of the water in the cleaning tank 3 and the leaking sound of the pump operating sound from the exhaust port 5a can be blocked, the quietness of the apparatus can be enhanced. Although the performance of blocking the exhaust duct 44 is inferior to that of an electric shutter or the like, the structure is simple, it is not affected by temperature, humidity or water, and the pressure inside the cleaning tank 3 is easy. There are also merits such as coming out.

Next, the rinsing process is started, but the basic operation is almost the same as the cleaning process. First, the water supply valve 10 is opened, water is supplied into the cleaning tank 3, and a predetermined water level is detected by the water level detection device 11. Is reached and the water supply valve 10 is closed.
Next, the washing pump 13 is energized, pressure is applied to the rinse water, and the nozzle 14 is used to spray the dishes 91. When a predetermined time elapses, the energization of the cleaning pump 13 is stopped and the drainage pump 16 is energized to drain the rinse water stored in the cleaning tank 3 to the outside. Such a rinsing process is repeated several times.

  Next, the heating and rinsing process is started. The basic operation is the same as that of the cleaning process, and heating of the rinsing water by the water heater 12 is added to the above-described rinsing process. The rinse water temperature is usually higher than the wash water temperature in order to improve the end of washing and the drying performance, and is generally set to be higher than 70 ° C. Therefore, the state of the air inside the cleaning tank 3 becomes higher than that during the cleaning process, and the degree of high-temperature wet air leaking increases. Wet air is not exhausted.

When the washing and rinsing steps as described above are completed, the drying step, which is the last step, is started.
FIG. 7 is an explanatory diagram showing the flow of air taken from the outside in the drying process. First, the drying fan 22 is energized, pressure is applied to the air, and the drying heater 23 is energized. The suction port of the drying blower has a door 5 on the upstream side of the exhaust duct or a space 5b between the door and the cleaning tank, and a portion of the door 5, for example, an upstream side of the exhaust duct 44 (lower side of the door) 5c. The outside air that is formed through the suction port cools the outer wall of the control device 10, the exhaust duct 44 and the cleaning tank 3, enters the inlet of the drying fan 22, and heats the air by the drying heater 23 to heat the air. It changes into wind and sprays on the tableware 91 from the tank ventilation opening 3a.

  Next, the warm air sent from the tank blower port 3a passes through the inside of the cleaning tank 3, enters the exhaust duct 44 from the tank exhaust port 3b, the shutter 43 is opened by the force of the warm air, and the device is connected to the external exhaust port 5a. Will be discharged to the outside. The state of the gas discharged for a while after the start of the drying process is the high-temperature humid air described so far. This is because the air in the cleaning tank 3 is the air dried by the drying fan 22. Since it is a short time only during the sequential replacement, the external exhaust port 5a does not reach condensation.

  Thus, since the air from the outside cools the control device 9, the exhaust duct 44, and the cleaning tank 3, it is useful for lowering the temperature of the high temperature member and lowering the heat capacity of the drying heater 23 by increasing the temperature of the air. Energy saving effect can be improved. Further, the air that has entered from the outside uses the cooling air passage on the upper surface side of the lid body 4, so that the upper portion of the housing 2 can be cooled as well as the lid body 4 that reaches a high temperature. For this reason, when the dishwasher 1 is incorporated in the sink, it is possible to prevent the sink from becoming hot.

  As described above, in the first embodiment, the cleaning tank 3 and the external exhaust port are provided by the shutter 43 provided in the exhaust duct 44 and the guide body 3c formed of a substantially U-shaped (or substantially U-shaped) rib. 5a can be shielded from the high-temperature humid air, so that the high-temperature humid air is not discharged from the external exhaust port 5a and the surroundings of the external exhaust port 5a are dewed except when the wind pressure from the drying fan 22 is supplied. There is nothing to do. For this reason, the clothes of the user are not wetted by condensation, and rust is not generated by condensation. In addition, since the sound can also be cut off, a situation in which water splash sound or pump operation sound in the cleaning tank 3 leaks from the external exhaust port 5a does not occur, and the quietness of the apparatus can be improved. .

Embodiment 2. FIG.
FIG. 8 is a longitudinal sectional view of the main part of the exhaust unit according to the second embodiment of the present invention, and FIG. 9 is a perspective view of the duct body according to the second embodiment.

A guide body (duct guide) 42 for rectifying the flow of the water is installed. The guide body 42 is formed of a member different from the cleaning tank 3, and a shutter 43 is rotated on the guide body 42. It is different from Embodiment 1 described above that it is supported freely.

  The guide body (duct guide) 42 is for rectifying the air in the exhaust duct 44 in order to eliminate high-temperature wet air leakage into the upper gap of the shutter 43, and is provided on the contact surface of the duct guide 42 on the shutter 43 side. Is formed with a duct guide seal surface 42a that is in close contact with the surface of the shutter 43 on the cleaning tank side without any gap. The duct guide seal surface 42a has a shape in which the lower side of the four sides of the rib is open, and the tip surface is devised such as increasing the surface width in order to improve the sealing performance.

  In the second embodiment, the guide body (duct guide) 42 is a separate body from the cleaning tank 3, and it is assumed that the cleaning tank 3 is usually made by molding an industrial mold such as plastic resin. However, since it is not molded integrally with the washing tub 3, there is no restriction on the shape, and it is possible to avoid damage due to, for example, a collision during transportation by transporting in an unassembled state during transportation. And transportability is improved. The seal surface 42a of the guide body (duct guide) 42 can secure a sufficient seal surface width, and the effects similar to those of the first embodiment can be further improved. The same effect can be obtained if the seal surface 42a of the guide body (duct guide) 42 is not only substantially U-shaped as shown in FIG. 9 but also substantially U-shaped (FIG. 5B).

  In addition, since the shutter 43 is movably supported by the guide body 42, the sealing state of the shutter 43 and the guide body 42 can be confirmed before the exhaust unit 41 is attached. improves.

FIG. 10 is a longitudinal sectional view of a main part of the exhaust unit according to the third embodiment of the present invention, and FIG. 11 is a perspective view of the shutter according to the third embodiment. In this third embodiment, the system is the same as that of the first and second embodiments, but the shutter 43 in the exhaust duct 44 is provided with a shutter rib 43b that inhibits the flow of hot humid air. Thus, the configuration is such that the four sides of the shutter seal surface 43a are enclosed, which is different from the first and second embodiments.

  In the third embodiment, the shutter 43 is configured to surround the four sides of the shutter seal surface 43a with the shutter rib 43b, so that a gap for opening the shutter 43 is provided between the lower portion of the shutter 43 and the exhaust duct 44. Is closed, and the gap below the shutter 43 can be compensated by the effect of obstructing the flow of high-temperature wet air in the shutter rib 43b, and the same effects as those of the first and second embodiments are further improved. Can be made.
