In the present embodiment, both the upper end and the lower end of the cover 70 form the opening O. In the present embodiment, the opening O is formed between the cover 70 and the back panel 5. The opening O constitutes a flow path for guiding the water vapor in the cleaning chamber 3 to the exhaust port 2H.

  Subsequently, the operation of the dishwasher 1 will be described. As shown in FIG. 2, when the power switch is turned on, the dishwasher 1 sprays the hot water in the hot water storage tank 28 into the washing chamber 3 by the rinse pump 34, whereby the hot water is introduced into the washing water tank 15. Supplied. The temperature of the hot water in the hot water storage tank 28 is set, for example, to about 80 ° C. Thus, initial hot water supply is performed. Then, the amount of detergent suitable for the initial hot-water supply amount is supplied into the cleaning water tank 15, and the detergent concentration of the cleaning water in the cleaning water tank 15 becomes a predetermined concentration.

  After the initial hot water supply, when the user racks the tableware P and closes the door 7, the door switch (not shown) detects that the door is closed and the operation start signal is a microcomputer (not shown). Input to When the operation start signal is input to the microcomputer, the cleaning of the dishes is started. The washing of the dishes is performed by spraying the washing water in the washing water tank 15 toward the dishes P in the washing chamber 3. The temperature of the wash water in the wash water tank 15 is set to, for example, 60 ° C. to 70 ° C.

  When the cleaning pump 23 is started, the cleaning water stored in the cleaning water tank 15 is pressure-fed to the upper cleaning nozzle 12A and the lower cleaning nozzle 12B through the cleaning water discharge pipe 24 etc., and the upper cleaning nozzle 12A And it is jetted toward the dishes P in the washing room 3 from the lower side washing nozzle 12B. At this time, since the upper cleaning nozzle 12A and the lower cleaning nozzle 12B continue to rotate due to the reaction force of the jet force, the cleaning water is evenly applied to the tableware P, and the stains of the tableware P are efficiently washed out.

  The washing water jetted into the washing chamber 3 is collected in the washing water tank 15 while residual vegetables and the like washed from the dishes P are removed by the first filter 14. Furthermore, after fine residual vegetables are removed by the filter 18, it is circulated and supplied again into the washing chamber 3 by the washing pump 23.

  Next, when the rinse pump 34 is started, the rinse water stored in the hot water storage tank 28 is pressure-fed to the upper and lower rinse nozzles 13A and 13B through the rinse water discharge pipe 36 etc. 13A and 13B are jetted toward the tableware P. The temperature of the rinse water pressure-fed from the hot water storage tank 28 is set, for example, to about 80.degree. At this time, since the rinse nozzles 13A and 13B also continue to rotate by the reaction force of the injection force, the rinse water is uniformly applied to the tableware P, and the rinse of the tableware P is efficiently performed.

  The rinse water jetted to the tableware P is collected in the wash water tank 15 through the first filter 14 and mixed with the wash water, and is used as wash water in the next washing step. When rinse water is jetted into the cleaning chamber 3 and collected in the wash water tank 15, excess wash water exceeding a certain water level is drained from an overflow (not shown).

  When the rinse water is sprayed from the upper and lower rinse nozzles 13A and 13B to the tableware P, water vapor is generated in the cleaning chamber 3. In the dishwasher 1 of the present embodiment, when the rinsing process is started, the exhaust fan 68 starts operation, and the water vapor generated in the cleaning chamber 3 is discharged by the exhaust fan 68. The operation start timing of the exhaust fan 68 is not limited to this timing, and may be started from the cleaning step in which water is jetted from the upper cleaning nozzle 12A and the lower cleaning nozzle 12B.

  When the water vapor is discharged from the cleaning chamber 3 by the exhaust fan 68, the water vapor is sent out to the heat exchanger 64 of the heat exchange unit 60 through the exhaust port 2H. Specifically, the water vapor in the cleaning chamber 3 rises above the cleaning chamber 3, passes through the opening O between the cover 70 and the back panel 5 and / or the penetrating portion 72, and passes through the exhaust port 2H. Flows into the heat exchange unit 60. The water vapor flows through the flow path in which the heat exchanger 64 is disposed. In the heat exchanger 64, heat exchange is performed between the “water vapor” flowing in the flow path and the “water” flowing in the heat exchanger 64.

  When the recovery of water vapor in the cleaning chamber 3 is performed for a predetermined time by the operation of the exhaust fan 68, the operation of the exhaust fan 68 is stopped. When the operation of the exhaust fan 68 is stopped, the flow of water vapor to the heat exchanger 64 is stopped. At this time, almost no water vapor (vapor) is present in the cleaning chamber 3.

  Then, the effect of the dish washer 1 of this embodiment is demonstrated. A seal portion 42 and a seal portion 44 are provided in the washing machine body 2 of the dishwasher 1 in order to prevent the water vapor in the washing chamber 3 from leaking between the door 7 and the back panel 5 to the outside. There is. The seal portion 42 and the seal portion 44 are disposed on the upper side and the rear side of the washing machine body 2. In this configuration, the exhaust port 2H for exhausting the water vapor in the cleaning chamber 3 to the heat exchange unit 60 is disposed below the seal portion 42 and the seal portion 44. By its nature, the water vapor rises in the washing chamber 3 and accumulates in the upper part of the washing chamber 3. Further, when the exhaust fan 68 is turned on, the outside air is sucked into the cleaning chamber 3 from the clearance around the lower end of the door 7, and a flow from the lower end of the door 7 to the exhaust port 2H is formed. Therefore, the flow of water vapor formed in the cleaning chamber 3 by the exhaust fan 68 is unlikely to be formed above the cleaning chamber 3. Therefore, the water vapor in the upper part of the cleaning chamber 3 does not easily reach the exhaust port 2H.

  In the dishwasher 1 according to the present embodiment, the washer body 2 has a cover 70. At least the upper end portion of the cover 70 forms an opening O communicating the cleaning chamber 3 with the exhaust port 2H. That is, at least the upper end portion of the cover 70 constitutes a part of a flow path of water vapor from the cleaning chamber 3 to the exhaust port 2H. In this configuration, the water vapor reaches at least the exhaust port 2H through the opening O formed at the upper end of the cover 70. Therefore, the accumulated water vapor above the cleaning chamber 3 can be guided to the exhaust port 2H. Therefore, the water vapor in the cleaning chamber 3 can be efficiently discharged to the heat exchange unit 60. As a result, the dishwasher 1 can efficiently recover the water vapor.

  Further, in the dishwasher 1, the cover 70 is disposed at a position overlapping at least a part of the exhaust port 2H as viewed from the front of the exhaust port 2H. Thereby, the cover 70 can prevent the cleaning water in the cleaning chamber 3 from entering the heat exchange unit 60. Further, the cover 70 can prevent the operator's hand from entering the heat exchange unit 60 at the time of maintenance or the like.

  In the dishwasher 1 according to the present embodiment, the cover 70 is a plate member. The cover 70 is disposed such that one main surface 70a faces the exhaust port 2H, and the cover 70 is spaced apart from the exhaust port 2H by a predetermined distance. In this configuration, an opening O is formed at the upper end and the lower end of the cover 70 and both ends. Therefore, the water vapor passes from the opening O formed around the cover 70 to the exhaust port 2H. Therefore, the steam can be recovered more efficiently. Further, since the opening O is also formed at the lower end portion of the cover 70, drain water (water generated by condensation of water vapor in the heat exchanger 64) or cleaning water etc. discharged from the heat exchange unit 60 Can be discharged into the cleaning chamber 3 through the

  In the dish washer 1 according to the present embodiment, the cover 70 is provided with a penetrating portion 72 penetrating between the one main surface 70a and the other main surface 70b opposed to the one main surface 70a. There is. In this configuration, the water vapor passes from the cleaning chamber 3 to the exhaust port 2H through the penetration portion 72. Therefore, the water vapor in the cleaning chamber 3 can be more efficiently discharged to the heat exchange unit 60.

Second Embodiment
