no. 1 Embodiment

[0037] figure 1 It is a sectional view schematically showing the dishwasher 10 of the first embodiment. Inside the housing 14 of the dishwasher 10 is provided a washing tank 4 for washing and drying various kinds of dishes stored in the dish basket 54 . The cleaning tank 4 has a box shape having an opening at the top, and a door 40 is provided on the front surface. The cleaning tank 4 can be pulled out from the casing 14, and then various tableware can be taken out from the upper opening of the cleaning tank 4.

[0038]Inside the casing 14 is provided an upper cover 6 that seals the upper opening of the cleaning tank 4 . The range of movement of the upper cover 6 is limited by a guide member not shown in the figure. After the cleaning tank 4 is pulled out from the casing 14, the upper cover 6 is obliquely upward relative to the cleaning tank 4 ( figure 1 upper left in ) and then stops inside the housing 14. After the cleaning tank 4 is pushed into the shell 14, the upper c...

no. 2 Embodiment

[0065] Description of the same parts as those in the first embodiment will be omitted. The dishwasher 10 of this embodiment has the same structure as that of the first embodiment, but the content of the operation is different.

[0066] The following combination Figure 5 The operation content of the dishwasher 10 of this embodiment will be described.

[0067] After the dishwasher 10 starts to operate in step S32, the washing tank 4 drives the drain pump 36 in step S34 to discharge the water stored in the bottom of the washing tank 4 from the washing tank 4.

[0068] In step S36, it is judged whether the minimum water level switch 32 is closed, and if the minimum water level switch 32 is connected (no situation in step S36), the controller 45 makes the judgment of unfinished drainage, and enters step S38 . In step S38, it is determined whether or not the elapsed drainage time from the start of drainage has reached 3 minutes. If the drainage has not been completed and 3 minu...

no. 3 Embodiment

[0081] Below, combine Figure 6 to Figure 8 Another dishwasher 100 of the present invention will be described.

[0082] The same reference numerals are assigned to the same parts as those of the dishwasher 10 in the first and second embodiments, and description thereof will be omitted.

[0083] Figure 6 It is a sectional view schematically showing the dishwasher 100 of this embodiment. The structure of the dishwasher 100 is basically the same as that of the dishwasher 10. The dishwasher 100 does not have the pressure sensor 7, but has a displacement gauge 9 (equivalent to a detection mechanism for detecting pressure fluctuations) instead. The displacement gauge 9 is a contact displacement gauge. , which is arranged outside the center of the upper cover 6 . Displacement meter 9 has measured loam cake 6 in the direction perpendicular to upper surface ( Figure 6 The displacement in the up and down direction) and output the measured result to the controller 45.

Abstract

PROBLEM TO BE SOLVED: To provide a technique to prevent water leakage by watching the sealed state of a washing tub with a simple device structure and suspending the operation when the sealed state is not retained.

SOLUTION: The dishwasher comprises the washing tub with an opening for storing dishes to be washed, a lid for closing the opening of the washing tub, a means of varying the pressure inside the washing tub, a means of detecting the variation of the pressure inside the washing tub, and a means of determining the sealed state of the opening based on the detected variation of the pressure inside the washing tub. The dishwasher changes the operation state when it is determined that the opening is not sealed.

Description

technical field [0001] The invention relates to a dish washing machine. Background technique [0002] The dishwasher has a washing tank in which dishes and the like are accommodated and washed. In the washing tank, dishes and the like are washed using a washing liquid. At this time, if the cleaning solution leaks from the cleaning tank, it will have a bad influence on the electrical system equipped in the dishwasher, or enzymatic changes will occur on the parts where the cleaning components contained in the cleaning solution are attached. In order to prevent the rinsing fluid from leaking out of the rinsing tank, the dishwasher also has a cover that seals the rinsing tank together with the rinsing tank. [0003] If the sealing of the cover is insufficient, the sealing performance of the cleaning tank cannot be ensured, and the cleaning liquid leaks out of the cleaning tank. In order to prevent the above-mentioned leakage of the washing liquid, various technical proposals ...
