More specifically, as can be seen from fig. 1, the two liner cups 15 of this embodiment are respectively connected to the outlet of the water softener 11 through one water softener outlet pipe 111, so as to achieve connection with the outlet of the water softener 11.

In addition, in this embodiment, waterway system still includes two on-off control devices that set up on connecting pipe, these two on-off control devices set up with two inner bags 2 one-to-one for through the control with each inner bag 2 correspond connecting pipe's break-make come control waterway system and two inner bag 2's intercommunication condition, can realize like this whether to carry out the control of cleaning work to two inner bags 2, make the dish washer of this embodiment can realize single inner bag cleaning condition and two inner bags cleaning condition, can satisfy more various user demands more nimble.

Moreover, the existing single-liner dish washer has the problems that the storage function of clean tableware and the cleaning function of dirty tableware are difficult to be considered, if the clean tableware is stored in the liner when the tableware is not required to be cleaned, when the tableware is required to be cleaned, the dirty tableware to be cleaned can be put into the liner for cleaning only after the clean tableware is taken out from the liner, the operation is complex, the use is inconvenient and the like, and if the clean tableware is not taken out from the liner, the clean tableware and the dirty tableware are directly cleaned together, and the problems of low cleaning efficiency, energy waste, repeated work and the like are also caused; but this embodiment's two inner bag dish washer can place clean tableware in one of them inner bag 2, only controls and carries out cleaning work in another inner bag 2 for dish washer can realize clean tableware's storage function (be equivalent to cupboard) and dirty tableware's cleaning function simultaneously, and it is more convenient to use, and need not disposable to wash all tableware, can effectively avoid work repeatability, helps improving cleaning efficiency.

Specifically, as shown in fig. 1, in this embodiment, each on-off control device includes a set of first control valves 16, a set of second control valves 17, and a set of third control valves 18, which makes the entire waterway system of this embodiment include two sets of first control valves 16, two sets of second control valves 17, and two sets of third control valves 18 in total, wherein: the first control valve 16 is arranged on a connecting pipeline between the corresponding liner water cup 15 and the inlet of the washing pump 12 and is used for controlling the on-off of the connecting pipeline between the corresponding liner water cup 15 and the inlet of the washing pump 12; the second control valve 17 is arranged on a connecting pipeline between the corresponding inner container 2 and the inlet of the washing pump 12 and is used for controlling the on-off of the connecting pipeline between the corresponding inner container 2 and the inlet of the washing pump 12; the third control valve 18 is disposed on the connecting line between the corresponding liner cup 15 and the inlet of the drain pump 13, and is used for controlling the on-off of the connecting line between the corresponding liner cup 15 and the inlet of the drain pump 13. When the two on-off control devices are opened, the waterway system is communicated with the two inner containers 2, so that washing fluid can be provided for the two inner containers 2 at the same time, and the washing fluid which is washed in the two inner containers 2 can be discharged, so that the two inner containers 2 can be washed; when one of the on-off control devices is closed, the waterway system is only communicated with the inner container 2 corresponding to the other on-off control device which is not closed, so that only the inner container 2 communicated with the waterway system can perform cleaning work.

It can be seen that by setting two sets of the first control valves 16, two sets of the second control valves 17 and two sets of the third control valves 18 corresponding to the two inner containers 2 one by one, this embodiment can control the water path system to be communicated with two or any one of the two inner containers 2, so that the two inner containers 2 can perform dish washing simultaneously, thereby realizing a double-inner-container washing condition, or only one of the inner containers 2 can perform dish washing, thereby realizing a single-inner-container washing condition.

It should be noted that, as shown in fig. 1, in this embodiment, the number of control valves included in each group of the first control valves 16, each group of the second control valves 17, and each group of the third control valves 18 is one, so that control over the cleaning condition can be achieved by using fewer control valves, and cost is saved; it will be appreciated by those skilled in the art that in other embodiments of the present invention, the number of control valves included in each set of first control valves 16, each set of second control valves 17, and each set of third control valves 18 may be two or more.

The arrow direction in fig. 1 is the flow direction of the washing fluid in the waterway system of this embodiment. The operation of the dishwasher of this embodiment will be described with reference to fig. 1:

(1) If the cleaning condition of the double inner containers is to be realized, that is, the left inner container 2 and the right inner container 2 in fig. 1 work, the first control valve 16, the second control valve 17 and the third control valve 18 in the two on-off control devices are opened, at this time, the waterway system is communicated with the two inner containers 2, and the washing fluid can flow into the two inner container water cups 15 for storage through the water inlet, the water inlet valve, the respirator, the water softener 11 and the two water softener outlet pipes 111 respectively; after the storage capacity meets the use requirement, closing the water inlet valve, opening the washing pump 12, and driving the washing fluid stored in the two liner water cups 15 by the washing pump 12 to be sprayed into the two liners 2 to clean tableware in the two liners 2, wherein in the process, the washing fluid circulates in the two liners 2, and the washing fluid after cleaning flows into the two liner water cups 15 for collecting and storing; after the tableware is washed clean, the washing pump 12 is turned off and the drain pump 13 is turned on, and the drain pump 13 drives the dirty washing fluid stored in the two liner cups 15 to flow to the drain pipe 14 and to be discharged through the drain port.

(2) If a single-liner cleaning condition is to be realized, in which only the left liner 2 works, the first control valve 16, the second control valve 17 and the third control valve 18 corresponding to the left liner 2 are opened, and the first control valve 16, the second control valve 17 and the third control valve 18 corresponding to the right liner 2 are closed, so that the waterway system is only communicated with the left liner 2, and therefore, the washing fluid reaching the water softener 11 from the water inlet can only flow into the left liner water cup 15 through the water softener outlet pipe 111 connected with the left liner water cup 15 (namely, the liner water cup 15 corresponding to the left liner 2) for storage; after the storage capacity meets the use requirement, closing a water inlet valve, opening a washing pump 12, and driving washing fluid stored in a left liner water cup 15 by the washing pump 12 to be sprayed into the left liner 2 to clean tableware in the left liner 2, wherein the washing fluid circulates in the left liner 2 in the process, and the washing fluid after cleaning flows into the left liner water cup 15 for collecting water and storing; after the tableware is washed clean, the washing pump 12 is turned off and the drain pump 13 is turned on, so that the drain pump 13 drives the dirty washing fluid stored in the left liner cup 15 to flow to the drain pipe 14 and to be discharged through the drain port.

(3) In order to achieve the single-liner cleaning condition in which only the right liner 2 works, only the first control valve 16, the second control valve 17 and the third control valve 18 corresponding to the right liner 2 are opened, and the first control valve 16, the second control valve 17 and the third control valve 18 corresponding to the left liner 2 are closed, so that the waterway system is only communicated with the right liner 2, and therefore, the washing fluid reaching the water softener 11 from the water inlet can only flow into the right liner cup 15 through the water softener outlet pipe 111 connected with the right liner cup 15 (i.e. the liner cup 15 corresponding to the right liner 2) for storage; after the storage capacity meets the use requirement, closing a water inlet valve, opening a washing pump 12, and driving washing fluid stored in a right-side liner water cup 15 by the washing pump 12 to be sprayed into the right-side liner 2 to clean tableware in the right-side liner 2, wherein in the process, the washing fluid circulates in the right-side liner 2, and the washing fluid after cleaning flows into the right-side liner water cup 15 to be collected and stored; after the tableware is washed clean, the washing pump 12 is turned off and the drain pump 13 is turned on, so that the drain pump 13 drives the dirty washing fluid stored in the right liner cup 15 to flow to the drain pipe 14 and to be discharged through the drain port.

It can be seen that, the dish washer of this first embodiment not only can effectively increase the memory space of tableware, improve cleaning efficiency for current single inner bag dish washer, moreover, because only need a set waterway system, only need set up a wash pump 12, a drain pump 13, a water inlet and a outlet, can supply two inner bags 2 work, consequently, compare in current two single inner bag dish washers, also can reduce the use of wash pump 12 and drain pump 13 etc. and to the occupation of kitchen tap and kitchen sewer line entry etc. simple structure, the cost is lower, it is more convenient to use.

Fig. 2 shows a second embodiment of the invention. As shown in fig. 2, similarly to the first embodiment, in this second embodiment, the dishwasher still includes two liners 2 and a set of waterway system capable of simultaneously supplying the two liners 2, and the water cup device of the waterway system still includes two liner water cups 15 connected between the two liners 2 and the inlet of the drain pump 13, that is, the second embodiment still uses two liner water cups 15 in one-to-one correspondence with the two liners 2 to achieve water collection and storage of the dirty washing fluid.

However, unlike the first embodiment, in this second embodiment, the two liner cups 15 are not connected between the water inlet and the inlet of the washing pump 12, that is, the storage of the washing fluid before entering the washing pump 12 is not realized by the two liner cups 15, but a common cup 19 is added, and the storage of the washing fluid before entering the washing pump 12 is realized by using the common cup 19, so that the water softener 11 is discharged without water diversion, and the washing pump 12 can directly pump water from the common cup 19 for washing, thereby further simplifying the connecting pipeline of the waterway system.

Specifically, as can be seen from fig. 2, in the second embodiment, the common water cup 19 is connected between the inlet and the water inlet of the washing pump 12, so that the washing fluid entering the dishwasher from the water inlet is stored in the common water cup 19 and enters each inner container 2 through the common water cup 19 under the driving action of the washing pump 12, thereby realizing dish washing. More specifically, the common water cup 19 is connected to the water outlet of the water softener 11 through a water softener outlet pipe 111, and the washing pump 12 is provided on the common water cup 19 with an inlet communicating with the common water cup 19, and since the washing pump 12 is directly provided on the common water cup 19, a connection line between the common water cup 19 and the washing pump 12 can be omitted, further simplifying a line structure.

Moreover, as shown in fig. 2, the common water cup 19 of this embodiment is also connected between the two liner water cups 15 and the inlet of the drain pump 13 at the same time, so that the inlet of the drain pump 13 is connected with the two liner water cups 15 through the common water cup 19, thereby enabling the dirty wash fluid stored in the two liner water cups 15 to enter the drain pump 13 through the common water cup 19 to be discharged, that is, the common water cup 19 of this embodiment can collect water for washing as well as water for supply and drainage.

As can be seen from fig. 2, in order to further simplify the piping structure, the drain pump 13 of this embodiment is also directly disposed on the common water cup 19 and the inlet is directly communicated with the common water cup 19, so as to omit the connecting piping between the inlet of the drain pump 13 and the common water cup 19.

Further, in order to more conveniently realize the concentration of the circulating water, the setting position of the common water cup 19 of this embodiment is set to be lower than the setting position of the at least two inner container water cups 15, so that the common water cup 19 is lower than the two inner container water cups 15 in the height direction, and thus the dirty washing fluid stored in the two inner container water cups 15 can conveniently flow into the common water cup 19 only under the action of gravity for the drainage pump 13 to drain.

In addition, as shown in fig. 2, the second embodiment is different from the first embodiment in that two on-off control devices for controlling the switching of the cleaning conditions are not included any more, but only include the second control valve 17 and the third control valve 18, so that the embodiment can achieve flexible switching between the dual-liner cleaning condition and the single-liner cleaning condition with fewer control valves. Also, since the common cup 19 is also connected between the two liner cups 15 and the inlet of the drain pump 13, the third control valve 18 of this embodiment is more specifically provided on the connection line of the liner cups 15 and the common cup 19.

In operation of the dishwasher of the second embodiment, the washing fluid first enters the common water cup 19 through the water inlet, the water inlet valve, the breather and the water softener 11, the washing pump 12 pumps water directly from the common water cup 19 for washing, and the dirty washing fluid sequentially flows into the liner water cup 15 and the common water cup 19 for concentrated circulation and is pumped and discharged by the drain pump 13. When the double-liner cleaning working condition is needed, only the two second control valves 17 and the two third control valves 18 are required to be opened, so that the washing fluid pumped out from the common water cup 19 by the washing pump 12 can be divided into two paths to be sprayed into the two liners 2, and synchronous cleaning is realized; when the cleaning working condition of the single liner is needed, only one second control valve 17 and one third control valve 18 corresponding to the liner 2 needing to be operated are needed to be opened.

It can be seen that, compared with the dishwasher of the first embodiment, the dishwasher of the second embodiment can further simplify the connection lines between the water softener 11 and the water cup device, between the water cup device and the washing pump 12, and between the water cup device and the drain pump 13 by providing the common water cup 19, so that the connection lines of the waterway system are simpler; and the number of the control valves can be reduced, the structure of the waterway system is further simplified, and the cost is saved.

Although the above two embodiments are described by taking the case of providing two inner containers 2 as an example, it should be noted that in other embodiments of the present invention, the number of inner containers 2 of the dishwasher may be three or more, that is, the dishwasher of the present invention may include at least two inner containers 2, correspondingly, the number of inner container cups 15 of the waterway system may be at least two, and the number of on-off control devices of the waterway system may be at least two, which may be only corresponding to the number of inner containers 2 and may be set in one-to-one correspondence with each inner container 2.

In addition, it should be noted that the water cup device of the present invention is not limited to the structure shown in the above two embodiments, for example, in order to implement the washing water collecting function and the draining water collecting function, the water cup device may further include two water cups between the water inlet and the inlet of the washing pump 12 and one common water cup between each liner 2 and the inlet of the draining pump 13; alternatively, the cup device may be provided with a common cup between the water inlet and the inlet of the washing pump 12 and between the respective liner 2 and the inlet of the drain pump 13, all of which are within the scope of the present invention.

In addition, in the embodiments of the invention, the water cup device can be provided with the filtering structure, so that the water cup device can not only play a role in storing and collecting water, but also play a role in filtering, and more thorough tableware cleaning is realized.

The foregoing description of the exemplary embodiments of the invention is not intended to limit the invention to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
