  In FIG. 1, a housing 27 accommodated in the system kitchen is provided with a cleaning tank 29 that accommodates and cleans tableware 28. The washing tank 29 is provided at the lower part thereof so that it can be pulled out in the front-rear direction along a set of rails 30 that are installed substantially horizontally on the inner sides of both sides of the housing 27. A table basket 31 for storing the class 28 is arranged, and a cleaning nozzle 32 is rotatably provided at the bottom of the cleaning tank 29 below the table basket 31. Inside the cleaning tank 29, a heating means 33 such as a heater for heating the stored cleaning water, and a drain port 34 are provided at the bottom of the cleaning tank 29.

  A cleaning pump 35 is disposed outside the bottom of the cleaning tank 29 and pressurizes the cleaning water accumulated in the drain port 34 and sends it to the cleaning nozzle 32. The cleaning water collected in the drain port 34 is pressurized and circulated by the cleaning pump 35 and sprayed into the cleaning tank 29 from the spray hole 48 of the cleaning nozzle 32 to clean the dishes 28.

  The cleaning water stored in the cleaning tank 29 is supplied from a water supply pipe through a water supply hose and a water supply valve (both not shown). When the water level detecting means (not shown) communicating with the cleaning tank 29 detects that the cleaning water has been supplied to the predetermined cleaning water level 47, the control means closes the water supply valve and stops the supply of the cleaning water to the cleaning tank 29. It is configured as follows.

  In addition, a lid 37 for closing the opening 36 of the cleaning tank 29 is movably disposed above the casing 27 and can be moved up and down by a pair of left and right parallel link mechanisms 38 including a pair of front and rear links. A first seal member 39 made of an elastic body such as rubber is supported and sealed to the opening 36 of the cleaning tank 29. When the cleaning tank 29 is pulled out, the first seal member 39 is moved to the cleaning tank 29. It is configured to be displaced upward so as not to interfere with the movement of the front and rear.

  Here, the configuration of the cleaning tank 29 will be described with reference to FIGS. The cleaning tank 29 has an opening 36 on the upper side, and includes a resin cleaning tank member 40 that constitutes a side surface and a resin bottom constituent member 41 that constitutes a bottom part.

  The bottom component member 41 is configured in a bottomed tray shape, and a second seal member 42 made of an elastic body such as rubber is disposed at the outer peripheral upper end portion. The bottom component member 41 is provided with a second seal member 42. A groove 43 opened upward for holding is formed in an annular shape.

  Further, the bottom component member 41 includes a movable rail portion of the rail 30, a washing nozzle 32, a heating means 33, a washing pump 35, a pump motor, a water level detection means, a temperature sensor, and the like electrical components necessary for controlling the operation of the dishwasher. Most of the mechanical parts are mounted and unitized.

  Seal ribs 44 that suppress the second seal member 42 from above and cooperate with the groove portion 43 of the bottom component member 41 to exhibit water tightness are respectively provided at the front, rear, left and right outer peripheral lower ends of the cleaning tank member 40. A shield rib 45 is provided on the inner side. The shielding ribs 45 on both side surfaces of the cleaning tank 29 are provided without any step from the side inner wall 40 a of the cleaning tank member 40.

  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 are joined in the vertical direction, and a seal portion 54 constituted by the groove portion 43, the seal rib 44, and the second seal member 42 is joined to the joint portion. It is provided with a watertight seal. A recovery space 46 is provided between the shielding rib 45 and the groove 43 so as to prevent the cleaning water from being sucked up by capillary action so as to communicate over the entire circumference of the cleaning tank 29, so that the cleaning water reaches the seal portion 54. It is preventing. The tip of the shielding rib 45 is configured such that the gap with the bottom component member 41, that is, the size of the entrance 46 a of the recovery space 46 is smaller than the main space 46 b of the upper recovery space 46.

  Further, the tip of the shielding rib 45 is configured to be positioned above the prescribed cleaning water level 47 and below the injection holes 48 provided in the plurality of cleaning nozzles 32, and the bottom surface portion of the bottom component member 41. It is configured in a position where splashing water from the washing water does not splash. 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. 4 is configured in a substantially identical shape over the entire circumference of the cleaning tank 29 excluding the tableware basket support portion 53.

  As shown in FIG. 3, 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 upper part 53b is opposed to the upper part of the support lower part 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 of the rail receiving portion 50, ribs 50a are extended downward so as to cover the movable rail portion of the rail 30 from above and from the outside, thereby enhancing the mechanical strength of the rail receiving portion 50 and the lid. The cleaning water dropped from the body 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. 4, 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 engages with the convex part 51 provided in the cleaning tank member 40, and the vertical direction is regulated, and the cleaning tank member 40 and the bottom component member 41 are combined and integrated. 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.

Since 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 main space 46b of the upper recovery space 46, the water to the recovery space 46 Infiltration can be reduced. Further, the lower end of the shielding rib 45 has a prescribed cleaning water level 47.
Therefore, foreign matter or oil washed away from the tableware 28 does not accumulate in the recovery space 46, and does not hinder recovery of the cleaning water. 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, the lower end of the shielding rib 45 is configured above the predetermined washing water level 47, so that foreign matter or oil washed away from the tableware 28 does not accumulate in the collection space 46, thereby preventing the washing water from being collected. There is nothing. Moreover, generation | occurrence | production of a strange odor etc. can be suppressed.

  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, like a conventional dishwasher washing tank, if the tableware basket support portion 53 is integrally formed from 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, 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 so that water does not leak from the junction of the washing tub even when the sealing performance of the sealing member is deteriorated due to a drawer operation or long-term use. Therefore, it is useful as a dishwasher or the like for washing dishes by jetting washing water.
