Description

  The present invention relates to a built-in type dishwasher that cleans dishes and the like by spraying washing water.

  Conventionally, as shown in FIG. 7, this type of dishwasher is housed in a system kitchen, is provided inside the housing 1, and the washing tub 2 formed integrally with the bottom portion and the side portion is opened upward. 3 is provided, and a tableware basket 5 for storing tableware 4 is arranged inside. A washing nozzle 6 is rotatably provided below the tableware basket 5, and the washing water stored in the washing tank 2 is pressurized and circulated by the washing pump 7 and sprayed from the washing nozzle 6 to wash the tableware 4. . A rail 8 is fixed below the cleaning tank 2 and supported so as to be movable in the front-rear direction. When the tableware 4 is put in and out, the washing tub 2 stored in the housing 1 is pulled forward, and the tableware 4 is accommodated from the opening 3.

  In such a built-in type dishwasher in which the washing tub 2 is pulled forward from the housing 1 and the tableware 4 is taken in and out from the upper opening 3, outside air is fed into the washing tub 2 from the blower opening 62 during the drying process. It is necessary to provide the ventilation path 60 outside the outer wall of the cleaning tank 2 and in a limited space. In addition, since the air passage 60 is naturally airtight and communicates with the air blowing means 61 such as the air blowing fan, water tightness is also required. Further, the washing water in the washing tank 2 is supplied from the air blowing port 62. It is also necessary to prevent intrusion.

  Therefore, as shown in FIG. 7, an intake cover member 59 configured separately from the cleaning tank 2 is disposed outside the outer wall of the cleaning tank 2, and the side wall of the cleaning tank 2 and the intake cover member 59 are separated from each other. The pipe-shaped air flow path 60 is configured in a small size, and air is blown into the cleaning tank 2 from the air blowing port 62 provided in the cleaning tank 2 via the air blowing path 60 by the air blowing means 61. The air intake cover member 59 is fixed to the cleaning tank 2 via a seal member (not shown) made of an elastic body to prevent water leakage and wind leakage (see, for example, Patent Documents). 1).

  As shown in FIG. 7 at the same time, as a configuration for preventing cleaning water falling from above the blower opening 62 from entering the blower passage 60 during and after washing, the washing tank is disposed above the blower opening 62. A dishwasher having a structure in which a blower cover 63 that is separate from 2 is attached has been proposed (see, for example, Patent Document 2).

JP 2002-325714 A JP 2003-180602 A

  In the conventional configuration, since the cleaning tank 2 is formed integrally with the bottom and the side surface, the intake cover member 59 is provided outside the cleaning tank 2 in order to form the duct-shaped air passage 60. become. Further, most of the wash water falling from above by the blower cover 63 does not enter the blower path 60 and is collected at the bottom of the wash tank 2, but a small amount of wash water is from the gap between the wash tank 2 and the blower cover 63 and the like. In order to enter the ventilation path 60, the joint portion 64 between the cleaning tank 2 and the intake cover member 59 needs to be water-sealing. For this reason, the cleaning tank 2 and the intake cover member 59 are fixed to each other via a seal member or welded to be water-sealed.

  In addition, although it is possible to form the washing tank 2 and the blower cover 63 integrally, since the bottom part and the side part of the washing tank 2 are formed integrally, it is very difficult to form a mold.

  Further, even if the blower cover 63 and the cleaning tank 2 are joined in a watertight manner using a sealing member or the like, the cleaning water may enter from below the blower cover 63 due to vibrations when the cleaning tank 2 is pulled out. Therefore, the intake cover member 59 and the cleaning tank 2 need to be joined in a watertight manner.

  However, when considering long-term use, the water tightness of the joint 64 between the cleaning tank 2 and the intake cover member 59 is impaired due to poor welding and deterioration of the material due to heat cycle, detergent, oil, etc. It had the problem that it might lead to. The same applies to the case where the intake cover member 59 is sealed with a sealing member made of an elastic material.

  The present invention solves the above-mentioned conventional problems, in a dishwasher having a dishwasher body having an opening in the front and a washing tub provided so as to be freely drawn out from the opening, even when used for a long time, An object is to provide a dishwasher that does not leak water.

  In order to solve the above-described conventional problems, a dishwasher according to the present invention includes a dishwasher main body having an opening at the front, a washing tub provided so as to be freely drawn out from the opening, and a ventilation path in the washing tub. Air supply means for supplying outside air from the air blowing port, the cleaning tank is configured by engaging a bottom component member constituting the bottom part and a cleaning tank member constituting at least the side surface of the cleaning tank, The air flow path is located outside the outer wall of the cleaning tank, and is configured by engaging a lower divided path formed integrally with the bottom component member and an upper divided path formed integrally with the cleaning tank member. Is.

  As a result, the cleaning water that has entered the air blowing path from the air blowing port does not come into contact with the joint portion such as the welded portion, so that the occurrence of water leakage can be eliminated even when used for a long time.

  The dishwasher of the present invention can realize a dishwasher that does not leak even when used for a long time in a built-in type dishwasher.

Further, the tip of the shielding rib 45 is configured not to be positioned outside the side wall portion 49 of the bottom component member 41 over the entire circumference of the cleaning tank 29.

  In general, in a dishwasher, a dishwasher is dissolved in water to wash the dishes 28, but the wettability of the surface of the washing tub 29 is significantly increased by components such as a surfactant contained in the detergent. When the wettability is increased, the capillary phenomenon is very strongly generated. Therefore, the width of the recovery space 46 (main space 46b) is made wider than that in the case where normal water is used. The recovery space 46 has a shape that is communicated over the entire circumference, that is, the cross-sectional shape shown in FIG. 5 is formed in a substantially identical shape over the entire circumference of the cleaning tank 29 excluding the tableware basket support portion 53.

  Further, when the bottom structuring member 41 and the cleaning tank member 40 are joined to form the cleaning tank 29, the blowing path 56 is formed outside the outer wall on the front side of the cleaning tank 29 by the lower divided path 56 a and the upper divided path 56 b. At the same time, the opening 55a of the blowing means 55 and the opening 58a of the lid body 58 are joined together, and the blowing connection 56 and the blowing means 55 are coupled and connected. Further, the lower divided path 56a is formed in a convex shape in accordance with the shape of the upper divided path 56b, and the cross section of the air blowing path 56 is made to have substantially the same area, so that pressure loss during blowing is reduced.

  When forming the blowing path 56 by the lower divided path 56a and the upper divided path 56b, the outer peripheral part of the lower divided path 56a and the outer peripheral part of the part excluding the part corresponding to the opening 58a of the upper divided path 56b are sealed portions. 54 is formed, and both are joined by engagement between the convex portion 51 and the engagement hole 52a. As shown in FIG. 3, the seal portion 54 has the same configuration as the seal portion 54 formed at the junction between the outer peripheral upper end portion of the bottom component member 41 and the outer peripheral lower end portion of the cleaning tank member 40 described above. Detailed description is omitted here. In addition, the height position of the seal portion 54 in this portion is substantially the same height position as the seal portion 54 between the outer peripheral upper end portion of the bottom component member 41 and the outer peripheral lower end portion of the cleaning tank member 40.

A blower port 57 that blows outside air into the cleaning tank 29 through the blower path 56 is also formed along with the formation of the blower path 56 by joining the lower divided path 56a and the upper divided path 56b. As shown in FIGS. 1 and 3, the air blowing port 57 has a lowermost surface 56 e at the right end portion of the lower divided path 56 a formed at the right lower side of the front view and a right end portion of the upper divided path 56 b formed at the right lower side of the front view. It is formed by the upper surface 56f and the left and right side surfaces 56g and 56h of the umbrella-shaped portion 56c. Here, the sealing portion 54 that is the upper end of the bottom component 41 is positioned above the air blowing port 57, and even if the cleaning water enters from the air blowing port 57, the cleaning water touches the sealing portion 54 that is the joint portion. There is no configuration.

  Further, the bottom component member 41 and the seal portion 54 of the cleaning tank member 40 are disposed inside the opening 55 a of the blower means 55. Further, the upper end portion 56d in the air passage 56 is configured at a position higher than the air outlet 57, and even when a large amount of foam is generated due to misuse of the general detergent for kitchen, the foam is prevented from leaking to the air blowing means 55 side. It can be configured.

  As shown in FIG. 4, in the vicinity of the left and right side walls of the bottom in the washing tank 29, there are provided a plurality of left and right tableware basket support portions 53 for placing and supporting the tableware basket 31. The tableware basket support portion 53 is divided into a support portion lower portion 53 a provided on the bottom component member 41 and a support portion upper portion 53 b provided on the cleaning tank member 40. Then, as will be described later, the cleaning tank member 40 and the bottom component member 41 are joined to each other so that the support portion upper portion 53b is opposed to the upper portion of the support portion lower portion 53a as shown in FIG. A portion 53 is formed. Further, the height position of the lower surface 53c of the support portion upper portion 53b, which is the divided surface, is substantially the same height as the lower end of the shielding rib 45 of the cleaning tank member 40.

  Further, rail receiving portions 50 that support the weight of the cleaning tank 29 are formed on both side surfaces of the bottom component member 41 outside the side wall portion 49 and almost directly below the groove portion 43. At the outer end portion of the rail receiving portion 50, a rib 50a is extended downward so as to cover the movable rail portion of the rail 30 from above and from the outside, and the mechanical strength of the rail receiving portion 50 is enhanced. The cleaning water dropped from the lid 37 onto the outer wall of the cleaning tank member 40 is prevented from entering the rail 30.

  An engaging portion 52 extends downward in a rib shape on the outer side of the seal rib 44 provided at the lower ends of the front, rear, left and right outer peripheral portions of the cleaning tank member 40. Several convex portions 51 are provided on the outer periphery of the groove portion 43 of the bottom component member 41, and an engaging hole 52 a is formed at a position corresponding to the convex portion 51 in the engaging portion 52 of the cleaning tank member 40. By inserting the member 40 from above the bottom component member 41, the engaging portion 52 is elastically deformed, the convex portion 51 is engaged with the engagement hole 52a, and the cleaning tank member 40 and the bottom component member 41 are joined. It is assumed to be configured. In the joined state, the lower ends of the engaging portions 52 on both the left and right side surface portions are configured to abut on the upper surface of the rail receiving portion 50. By configuring the joint between the cleaning tank member 40 and the bottom component member 41 as described above, both can be joined with a simple configuration, and the cleaning water dropped from the lid 37 onto the outer wall of the cleaning tank member 40 Intrusion into the second seal member 42 can be prevented.

  As shown in FIG. 5, the cross-sectional shape of the fixed rail portion of the rail 30 is formed such that a raised portion 30b is provided on the outer side of the movable mechanism portion 30a, and the outer side thereof is a groove 30c that is one step lower. And the lower end outer side of the rib 50a provided in the outer end part of the rail receiving part 50 of the bottom part constituting member 41 is positioned directly above or outside the raised part 30b, and passes through the outer wall of the cleaning tank member 40 from the lid body 37. The cleaning water dripped to the outside of the lower end of the rib 50a is guided to the groove 30c and prevented from entering the movable mechanism 30a of the rail 30. Further, although not shown, a through-hole is provided in the rear part of either the movable mechanism part 30a or the groove part 30c, and the wash water introduced and dropped is dropped on the inner bottom part of the casing 27 and disposed in the vicinity thereof. It is made to detect with the installed water leak detection sensor.

About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. In the cleaning tank 29, the engaging tank 52 is temporarily deformed by its own elasticity by inserting the cleaning tank member 40 from above the bottom component member 41 on which the second seal member 42 is set. The joint hole 52a is engaged with the convex portion 51 provided in the bottom component member 41, the vertical direction is restricted, and the cleaning tank member 40 and the bottom component member 41 are combined and integrally formed. At that time, the seal rib 44 of the cleaning tank member 40 presses the second seal member 42 from above to deform it to a specified tightening position, and seals the joint. By integrating the cleaning tank 29, the recovery space 46 is configured by the shielding rib 45 provided in the cleaning tank member 40 and the groove 43 of the bottom component member 41. Here, the second seal member 42 is configured as an elastic body, but can be water-sealed with a silicon adhesive or the like.

  By combining and integrating the cleaning tank member 40 and the bottom component member 41, the lower divided path 56a and the upper divided path 56b are also combined and integrated to form the air blowing path 56 and the seal portion 54 around the air blowing path 56. Formation of the air blowing port 57 and coupling connection between the air blowing path 56 and the air blowing means 55 are performed.

  The shielding rib 45 provided on the inner side of the groove 43 is arranged so that the size of the entrance 46a of the recovery space 46 is smaller than the width of the main space 46b of the upper recovery space 46. Can reduce the infiltration of water. Further, since the lower end of the shielding rib 45 is located above the prescribed washing water level 47, foreign matter or oil washed away from the tableware 28 does not accumulate in the collection space 46, and the washing water can be collected. There is no hindrance. Moreover, generation | occurrence | production of a strange odor etc. can be suppressed.

  Furthermore, since the lower end of the shielding rib 45 is positioned below the ejection hole 48 of the cleaning nozzle 32, the cleaning water ejected from the ejection hole 48 is reliably blocked by the shielding rib 45. Only the cleaning water having a low momentum falling from above the cleaning tank 29 comes into contact with the inlet 46a of the cleaning tank 29, so that the water flow having pressure does not reach the groove 43.

  The cleaning water sprayed from the spray hole 48 hits the tableware 28 and falls as it is, or flows down along the side surface of the cleaning tank member 40 and flows to the lower end of the shielding rib 45. At this time, the tip of the shielding rib 45 is configured not to be positioned outside the side wall portion 49 of the bottom component member 41 over the entire circumference of the cleaning tank 29, so that the cleaning water flowing down along the shielding rib 45 from above is Then, it is recovered to the bottom surface of the bottom component member 41 without entering the recovery space 46.

  Further, since the shielding ribs 45 on both side surfaces of the cleaning tank 29 are provided without any step from the inner wall 40a of the cleaning tank member 40, there is no unnecessary step, the cleaning water recovery speed is not reduced, and the design is also good. Be improved.

  In addition, since the sealing portion 54 and the recovery space 46 for sealing the joint portion are formed simultaneously with the joining of the bottom component member 41 and the cleaning tank member 40, the joining operation and the formation of the sealing portion 54 and the recovery space 46 are easy. Thus, the assembly workability can be improved.

  Even in such a configuration, if the clearance of the recovery space 46 (main space 46b) is formed, the cleaning water that has touched the inlet 46a of the recovery space 46 is sucked up by capillary action and reaches the groove 43. End up. According to the present invention, since the recovery space 46 between the shielding rib 45 and the groove 43 is provided with a gap that does not allow the cleaning water to be sucked up by capillary action, even if the cleaning water comes into contact with the inlet 46a of the recovery space 46, The washing water is not sucked up into the groove 43.

As described above, according to the present invention, the cleaning water sprayed from the cleaning nozzle 32 does not reach the groove portion 43, and even if the second seal member 42 is not provided, water does not leak from the joint portion. However, when the cleaning water is heated, steam is generated, so that condensation occurs near the groove 43 and a small amount of water may leak out of the cleaning tank 29. For this purpose, in the present invention, the second seal member 42 is disposed on the outer upper side of the recovery space 46. Further, since water is not leaked even without the second seal member 42, the seal is caused by the deterioration of the second seal member 42 due to long-term use, and the vibration and force due to the pulling operation repeatedly applied to the groove 43. Even if the performance drops, water leakage does not occur.

  Further, since the recovery space 46 is configured to communicate with the entire circumference of the cleaning tank 29, when the cleaning tank 29 is pulled out and operated, the cleaning water reaches above the specified cleaning water level 47 and enters the recovery space 46. Even if the cleaning water permeates, there is a space for the cleaning water to escape in the lateral direction due to the communication recovery space 46, so that the cleaning water reaching the groove 43 can be greatly reduced. Of course, even when the cleaning water reaches the groove portion 43, the second sealing member 42 seals the water, so that no water leaks.

  As described above, in the present embodiment, the seal portion 54 for water-sealing the joint portion constituted by the upper end portion of the bottom portion constituting member 41 and the lower end portion of the cleaning tank member 40 is configured, and the seal portion 54 is A second sealing member 42 for sealing, and the cleaning tank member 40 is provided with a shielding rib 45 on the inner side of the sealing portion 54. Between the sealing portion 54 and the shielding rib 45, the cleaning water becomes a capillary phenomenon. By providing the recovery space 46 that prevents the water from rising and reaching the seal portion 54, the cleaning water does not reach the seal portion 54 in normal use, and the second time during the drawer operation or long-term use. Even when the sealing performance of the sealing member 42 is deteriorated, water leakage can be prevented.

  Further, as in the case of a washing tank of a conventional dishwasher, if the tableware basket support portion 53 is formed integrally with the bottom component member 41 and rises upward, it can be easily analogized if applied to FIG. A gap opened upward is formed between the tableware basket support part 53 and the shielding rib 45, and the sprayed cleaning water easily enters the recovery space 46 from the gap through the inlet 46a. In this embodiment, the tableware basket support portion 53 is divided into a support portion lower portion 53a provided on the bottom component member 41 and a support portion upper portion 53b provided on the cleaning tank member 40 so as to face the upper portion of the support portion lower portion 53a. In addition, the height position of the dividing surface is set to be substantially the same as the lower end of the shielding rib 45 of the cleaning tank member 40, so that the support lower part 53 a provided in the bottom component member 41 and the cleaning tank member 40 are provided. Since the gap between the holding portion upper portion 53b is formed in a substantially horizontal direction, it is difficult for the cleaning water sprayed into the gap to enter, and it is expected that the entering cleaning water will drop and return to the cleaning tank 29 side. The washing water can be prevented from flowing into the collection space 46 from the tableware basket support part 53.

  Further, by combining and integrating the cleaning tank member 40 and the bottom component member 41, the lower divided path 56a formed integrally with the bottom component member 41 and the upper divided path 56b formed integrally with the cleaning tank member 40 are also combined and integrated. Since the air passage 56 is thereby formed, the cleaning water that has entered the air passage 56 is collected in the cleaning tank 29 without contacting the welded portion or the joint portion. It is possible to prevent the cleaning water that enters 56 from leaking out of the cleaning tank 29.

  In addition, since the air blowing port 57 is also formed by engaging the lower divided path 56a and the upper divided path 56b, the joint between the air blowing port 57 and the air blowing path 56 can be eliminated, and cleaning from there Leakage of water out of the washing tank 29 can be prevented.

Further, the air outlet 57 of the air passage 56 formed by joining the cleaning tank member 40 and the bottom component member 41 is configured to blow air toward the heating means 33 (see FIG. 1), thereby heating the outside air. Since the tableware 28 can be dried, drying performance can be improved. At this time, since the outside air sent from the blowing means 55 is sent to the heating means 33 in a rectified state by the umbrella-shaped portion 56c, the outside air can be efficiently heated. The lower divided path 56a, the upper divided path 56b, and the umbrella-shaped portion 56c are matched to the flow of the outside air flowing in the air blowing path 56
Needless to say, if a structure such as a rib is provided to adjust the flow to the heating means 33, it can be heated more efficiently. Further, since the umbrella-shaped portion 56 c is formed integrally with the cleaning tank member 40, there is no gap, and there is no fear that the cleaning water falling from above the cleaning tank 29 enters the ventilation path 56.

  Moreover, since the upper end of the bottom part component 41 is comprised above the ventilation opening 57, the washing water which permeated from the ventilation opening 57 does not touch a junction part directly, and eliminates a water leak also in long-term use. Can do.

  Moreover, since the seal | sticker part 54 of the bottom part structural member 41 and the washing tank member 40 is located outside the ventilation path 56, when a bubble generate | occur | produces in the washing tank 29 with a foodstuff or detergent, a bubble permeates from the ventilation port 57. Even if it does, water leak can be prevented. On the other hand, since the bottom component member 41 and the seal portion 54 of the cleaning tank member 40 are disposed inside the opening 55 a of the air blowing means 55, the cleaning water does not enter the air blowing means 55.

  In addition, by configuring the upper end portion 56d in the air blowing path 56 at a position higher than the air blowing port 57, even when a large amount of foam is generated due to misuse of the general detergent for kitchen, the foam leaks to the air blowing means 55 side. Can be prevented.

  Further, in the present embodiment, the rail receiving portions 50 that support the weight of the cleaning tank 29 are configured on both side surfaces of the bottom component member 41 that is the lower member of the cleaning tank 29 that is configured as a vertically bonded structure, thereby cleaning. The weight of the tank 29 and other parts is not applied in the direction in which the seal portion 54 is pulled away, and the sealing performance of the second seal member 42 can be maintained for a long time.

  Further, in the present embodiment, the bottom component member 41 is unitized by mounting most of the electrical components and mechanical components, thereby making the portion above the seal portion 54 of the cleaning tank member 40 larger and smaller. Even if a single bottom component 41 is used, it is possible to obtain washing tanks with different capacities, so that it is possible to easily cope with the production of dishwashers with different washing tank capacities, and to improve manufacturing efficiency. Can be made.

  In the present embodiment, it has been described that only the rotatable cleaning nozzle 32 is provided at the inner bottom of the cleaning tank 29. However, for example, another cleaning nozzle is provided inside the cleaning tank 29. However, the effect by this invention can be acquired and it is not excluded from this invention.

  As described above, the dishwasher according to the present invention is a built-in type dishwasher, and even when used for a long period of time, even if washing water enters the blowing path, water leakage from the blowing path can be prevented. It is useful as a dishwasher that cleans dishes by jetting water.
