Abstract: A washer includes: a supply-water storage section configured to store supply water; a wastewater storage section configured to temporarily store wastewater and a wastewater heat recovery device including a water supply channel through which the supply water is supplied to the supply-water storage section and a drain channel through which the wastewater is drained from the wastewater storage section, and configured to exchange heat between the wastewater flowing in the drain channel and the supply water flowing in the water supply channel. the wastewater heat recovery device is disposed below the washing chamber, and is provided in a machine chamber in which a pump configured to deliver the supply water from the supply-water storage section to the washing chamber is disposed, and the drain channel is connected to a drain hole of the wastewater storage section.

Abstract: A washer that enables efficient heat exchange and can prevent a decrease in flexibility in installation of the washer is provided. A washer 1 includes: a supply-water storage section 28 configured to store supply water W2 to be used for washing and rinsing an object P to be washed accommodated in a washing chamber 3; a wastewater storage section configured to temporarily store wastewater W1 that has been used for washing and rinsing the object to be washed; and a wastewater heat recovery device 450 including a water supply channel 52 through which the supply water is supplied to the supply-water storage section and a drain channel 51 through which the wastewater is drained from the wastewater storage section 15, and configured to exchange heat between the wastewater flowing in the drain channel and the supply water flowing in the water supply channel.

Abstract: This dishwasher utilizes a rod 58 whose upper end is linked to the proximal end of a rotary arm 10, and compression springs 53 and 54 linked to the proximal end of the rotary arm 10 via the rod 58. Thus, even if the compression springs 53 and 54 break, the elastic force of the compression springs 53 and 54 themselves is maintained, and furthermore, the compression springs 53 and 54 continue to be supported by the lower end of the rod 58 in a state of being positionally restricted with respect to a dishwasher main body 2. This prevents a door 7 in an open state from suddenly falling.

Abstract: The present invention provides a dishwasher which permits cost reductions while enabling increased strength. A reinforcement member is mounted between pillars, which are erected in the corners of a machine chamber, and a functional part for executing washing and rinsing is fixed to the reinforcement member. Here, an example of the functional part is a washing pump for delivering washing water. Furthermore, another example for the functional part is a connecting part for connecting electrical wiring between a control box and a detergent supply device or a booster or the like.

Abstract: A dishwashing machine executes a washing or rinsing step of jetting hot water accumulated in a tank into a washing room. The dishwashing machine includes a heater for heating the hot water in the tank, a temperature sensor for measuring the temperature of the hot water in the tank, and a heater control unit for controlling the heater so that the hot-water temperature in the tank becomes a set temperature, based on the measured value of the temperature sensor. The heater control unit is capable of controlling the heater so that the hot-water temperature in the tank becomes a waiting temperature that is lower than the set temperature, in a quiescent operating state in which the washing or rinsing step is not executed.

Abstract: In this dishwasher 1, a spring 33 utilized for moving a door 7 up and down is accommodated within a column 6 of a washer body 2, so as to be confined within the column 6, whereby the appearance becomes better while the spring 33 is protected against water. Also, the space between left and right columns 6, 6 can be utilized as a washing chamber 3, thus making it possible to expand the washing chamber 3, whereby the dishwasher can be made smaller while keeping the capacity of the washing chamber 3.

Abstract: In the dishwasher, a washing water distribution pipe on which washing nozzles are installed is arranged within a washing chamber, and is connected removably to a first connecting pipe that communicates with the outlet side of a washing pump. In the same way, a rinsing water distribution pipe on which rinsing nozzles are installed is arranged within the washing chamber, and is connected removably to a second connecting pipe that communicates with the outlet side of a rinsing pump. These connections are made within a washing water tank in the bottom of the washing chamber, therefore the washing water distribution pipe and the rinsing water distribution pipe can be easily installed and removed from the washing chamber. Moreover, the washing water distribution pipe and the rinsing water distribution pipe are unitized, so handling is extremely easy.

Abstract: A dishwasher is a type in which a part of wash water contained in a wash water tank is replaced with rinse water every washing cycle. The dishwasher determines whether a present washing cycle is in timing of executing a detergent increase supply processing or in timing of executing a detergent normal supply processing (S304). Based on this determination result, by the execution of the detergent increase supply processing, a supply amount of the detergent is increased (S309). Consequently, in the dishwasher, the detergent concentration in the wash water is properly adjusted.

Abstract: To provide a dishwasher for which the washing water distribution pipe provided with the washing nozzles and the rinsing water distribution pipe provided with the rinsing nozzles can be easily installed and removed from the washing chamber. In the dishwasher 1, a washing water distribution pipe 21 on which washing nozzles 12, 14 are installed is arranged within a washing chamber 3, and is connected removably to a first connecting pipe 31 that communicates with the outlet side of a washing pump 19. In the same way, a rinsing water distribution pipe 27 on which rinsing nozzles 13, 15 are installed is arranged within the washing chamber 3, and is connected removably to a second connecting pipe 33 that communicates with the outlet side of a rinsing pump 24. These connections are made within a washing water tank 17 in the bottom of the washing chamber 3, therefore the washing water distribution pipe 21 and the rinsing water distribution pipe 27 can be easily installed and removed from the washing chamber.
