The water is injected into the water inlet pipe 711 at a certain initial pressure, and the communication state between a clean water source and the water inlet pipe 711 can be changed through the control valve 715, so that whether clean water is injected into the flushing mixing assembly 72 of the liquid medicine mixing assembly 71 is controlled; the end of the water outlet pipe 712b, which is used for communicating with the input clear water, is connected with a clear water source so that the clear water can be injected into the end of the water outlet pipe 712b at a certain initial pressure, and the communicating state of the clear water source and the end of the water outlet pipe 712b can be changed through a valve between the clear water source and the end of the water outlet pipe 712 b; the end of the water outlet pipe 712b for outputting the cleaning water is communicated with the main washing mechanism 6 of the door lifting type dish washer, so that the main washing mechanism 6 can output the cleaning water formed by mixing clean water with solid machine washing liquid.

When the intelligent distributor 7 is required to output cleaning water formed by mixing the cleaning water and the solid machine cleaning liquid, a valve between a clean water source and the water outlet pipe 712b is opened so that the clean water is injected into one end of the water outlet pipe 712b at a certain initial pressure; the control valve 715 is opened, clear water is injected into the water inlet pipe 711 at a certain initial pressure, flows through the control valve 715 and the connecting pipe 716 in sequence, and is flushed towards solid machine washing liquid in the material box 722 after being subjected to reducing and boosting through the flushing pipe 7212, so that the end part of the water outlet pipe 712b, which is communicated with the water outlet 724, outputs high-concentration cleaning water formed by mixing clear water with the solid machine washing liquid, and in the process, the filter screen 7213 can receive the blocky solid machine washing liquid which falls due to flushing, so that the solid machine washing liquid is prevented from falling into the water outlet 724, blocking the water outlet 724 and affecting the normal water outlet of the water outlet 724; the high-concentration cleaning water is mixed with the clean water so that the other end of the water outlet pipe 712b can output the cleaning water for cleaning the tableware, and the amount of the high-concentration cleaning water added to the clean water in unit time of the liquid medicine mixing assembly 71 can be changed by adjusting the opening time of the control valve 715 in unit time, so that the mixing ratio of the clean water and the solid machine washing liquid in the cleaning water for cleaning the tableware is changed.

In the application of the intelligent dispenser 7 to a dish washing process, it is generally required that the intelligent dispenser 7 comprises two liquid medicine mixing components 71 for mixing a machine washing liquid and a clean water, a drier and clean water, and since the machine washing liquid comprises two solid machine washing liquid and liquid machine washing liquid, the drier is liquid, the intelligent dispenser 7 can be provided with two liquid medicine mixing components 71 for mixing the clean water and the liquid machine washing liquid/drier, or one liquid medicine mixing component 71 for mixing the clean water and the solid machine washing liquid, considering different application situations. The setting and installation of the plurality of liquid medicine mixing components 71 are simple superposition of setting and installation of the single liquid medicine mixing component 71, the working principle and the process are completely consistent, and the unfolding introduction is not performed.

It can be understood that the clean water source connected by the liquid medicine mixing component 71 can be directly connected with the clean water source through a pipeline, or the clean water pumped by the corresponding main washing pump 522 or the spraying pump 532 after the cleaning water in the main washing tank 52 or the spraying water tank 53 is processed, the output clean water can be connected with the main washing mechanism 6 or the spraying mechanism 8, after understanding the working principle of the intelligent distributor 7, a person skilled in the art can set a pipeline connection structure according to the requirements of water inlet and water outlet of the intelligent distributor 7, so that details are not repeated herein, but only the mixing points of the two liquid medicine mixing components 71 of the intelligent distributor 7 are pointed out.

Referring to fig. 5 and 6, the liquid medicine concentration detection assembly 74 is configured to collect collected concentration information of the cleaning water, the collected concentration information including machine washing liquid concentration information and dryer concentration information. The liquid medicine concentration detection assembly 74 comprises two concentration acquisition sensors for respectively acquiring the concentration of the washing liquid in water and the concentration of the drier, wherein the concentration acquisition sensors are used for acquiring the concentration of the washing liquid in water and the concentration of the drier in the washing liquid in the water, which are the prior art, and are not described in a developing way.

During installation, the two concentration acquisition sensors are respectively arranged at the bottom of the main water tank 52, specifically, a mounting hole matched with the concentration acquisition sensors is drilled at the bottom of the main water tank 52, the position of the mounting hole is far away from a cleaning water inlet and a cleaning water outlet of the main water tank 52 so as to reduce the influence of water flow in the main water tank 52 on the concentration acquisition results acquired by the concentration acquisition sensors, meanwhile, a heat source is generally arranged in the door lifting type dish washer, the position of the mounting hole is far away from the heat source so as to reduce the influence of the heat source on the concentration results acquired by the concentration acquisition sensors, the acquisition probes of the concentration acquisition sensors penetrate through the mounting hole from outside to inside, rubber rings are respectively sleeved on the mounting hole from two ends of the concentration acquisition sensors, and the fixing of the concentration acquisition sensors relative to the mounting hole and the sealing of gaps between the concentration acquisition sensors and the mounting hole can be realized through the rubber rings.

The control component 73 is coupled to the liquid medicine concentration detection component 74 to obtain the collected concentration information, and is coupled to the peristaltic pumping device 713 and the control valve 715 to control the pumping power of the peristaltic pumping device 713 and the opening duration of the control valve 715 in a unit duration, so as to control the working power of the peristaltic pumping device 713 and the opening duration of the control valve 715 according to the collected concentration information.

The control unit 73 is preferably a single-chip microcomputer controller, and control logic built in the single-chip microcomputer controller will be described below by taking control of adding a machine washing liquid as an example.

The concentration information of the washing liquid of the preset machine can be factory set according to national standard or industry standard, and can also be set by the staff. The process that the staff set up and predetermine quick-witted lotion concentration information is generally realized through the main control unit of dish washer, simply speaking, after this intelligent distributor 7 installs in the dish washer, singlechip controller and dish washer's main control unit signal connection can be to singlechip controller input predetermine quick-witted lotion concentration information through main control unit, and singlechip controller and main control unit's signal connection and the mode of controlling singlechip controller through main control unit are ripe prior art, and details are omitted.

When the concentration information of the machine washing liquid in the collected concentration information is smaller than the preset machine washing liquid concentration information, the singlechip controller controls the peristaltic pump to increase the working time in unit time or controls the electromagnetic valve to increase the opening time in unit time, so that the concentration of the machine washing liquid in the washing water can be increased.

The liquid medicine concentration detection module 74 detects the concentration of the machine washing liquid in the washing water after the tableware is actually washed, and the adding amount of the machine washing liquid is controlled by the value of the concentration of the machine washing liquid in the actual washing water, so that the control mode with the result as the guidance can better ensure that the concentration of the machine washing liquid in the washing water is the concentration of the preset machine washing liquid concentration information.

The adding control logic of the drier can control the operation time in the unit time of the peristaltic pump by referring to the mode of controlling the operation time in the unit time, and the description is omitted.

The peristaltic pump is controlled by the singlechip controller to change the working time in unit time and the opening time in unit time of the electromagnetic valve to be the mature technical means in the prior art, so that the development and introduction are not performed. It can be understood that the single-chip microcomputer controller can control the working power of the peristaltic pump to change the adding amount of the machine washing liquid/drier by controlling the working time in the unit time of the peristaltic pump, can control the opening degree of the electromagnetic valve to change the adding amount of the machine washing liquid by controlling the opening time in the unit time of the electromagnetic valve, and has a plurality of modes for changing the adding amount of the machine washing liquid/drier, which are not described in a one-to-one way.

Similarly, when the intelligent dispenser 7 includes a plurality of liquid medicine mixing components 71, pumping power of a plurality of peristaltic pumps and/or opening time of electromagnetic valves in unit time are/is controlled, it should be understood that on the basis of explicit control logic for controlling a single peristaltic pump and/or electromagnetic valve, control for controlling a plurality of peristaltic pumps and/or electromagnetic valves is simply superposition of single control logic, and a person skilled in the art can set a plurality of control logic which do not interfere with each other by himself after knowing the single control logic, so as to ensure brevity of the specification, a process of forming a plurality of control logic by the single control logic is not described.

In the process of actually applying the intelligent distributor 7, the single-chip microcomputer controller of the intelligent distributor 7 is in signal connection with a main controller, namely a processor, of a dish washer, a water outlet pipe 712 for mixing solid machine washing liquid and clear water is connected with the end part of a clear water source and the end part for outputting washing water is communicated with a main washing water inlet pipe, or a water inlet pipe 711 and a water outlet pipe 712 for mixing liquid machine washing liquid and clear water are communicated with the main washing water inlet pipe, so that quantitative addition of machine washing liquid in the main washing water is realized, and the dish washing efficiency and the washing effect are improved; the liquid medicine mixing component 71 water inlet pipe 711 and water outlet pipe 712 for mixing clear water and drier are communicated and arranged on the rinsing water supply pipe, so that the drier is quantitatively added into the rinsing water for rinsing, and the tableware cleaning efficiency and cleaning effect are improved.

In the working process of the door lifting type dish washing machine with the intelligent distributor 7, the working process of the intelligent distributor 7 is as follows: the control component 73 controls the medicament adding amount of the medicament mixing component 71 according to the acquired concentration information of the medicament in the acquired actual cleaning water, and can better ensure that the medicament concentration in the actual cleaning water accords with the preset medicament concentration, so that the possibility that the result of the added medicament amount in the clean water deviates from the expected medicament adding amount due to the structural accuracy limitation of the mixer or the operation accuracy limitation of staff is reduced, and further the possibility that the cleaning efficiency and the cleaning result are inconsistent with the expected result is reduced.

Embodiment two:

the present embodiment differs from the first embodiment in that:

referring to fig. 2 and 4, the liquid medicine mixing assembly 71 for mixing clean water and solid machine washing liquid further includes an anti-clogging mechanism 725, the anti-clogging mechanism 725 includes a circulation pipe 7252, a circulation pump 7251 and an electric control three-way valve 7253, the electric control three-way valve 7253 has a portion of which two ends are communicated with each other and arranged at a water outlet 724 of the water outlet pipe 712, the other end is communicated with one end of the circulation pipe 7252, the other end of the circulation pipe 7252 is communicated with a placing cavity 7211 and the communicating position is located above the filter screen 7213, and the circulation pump 7251 is communicated with the circulation pipe 7252 and provides water flow power from the end of the communicating placing cavity 7211 to one end of the electric control three-way valve 7253 for the circulation pipe 7252. The circulating pump 7251 and the electric control three-way valve 7253 are connected and controlled by the control component 73, namely a singlechip controller.

The singlechip controller also comprises the following control logic: normally, the electric control three-way valve 7253 is communicated with two ends of the water outlet pipe 712, and is not communicated with the other end, and the water outlet pipe 712 normally passes through high-concentration cleaning water; when the control component 73 controls the opening degree of the electromagnetic valve and the opening time in unit time to reach the maximum value, and the concentration information of the machine washing liquid in the collected concentration information is still smaller than the concentration information of the preset machine washing liquid in the preset concentration information, which indicates that the filter screen 7213 may be blocked by the washing dropped blocky solid machine washing liquid, at the moment, the singlechip controller drives the anti-blocking mechanism 725 to perform blocking cleaning work, namely, controls the electric control three-way valve 7253 to change the connection state until the end part of the connection water outlet 724 is communicated with the end part of the connection circulating pipe 7252 and the other end is not communicated, and drives the circulating pump 7251 to start, high-concentration washing water in the water outlet pipe 712 is reversely sprayed and washed to the filter screen 7213, so that the meshes blocked by the top-down filter screen 7213 are washed through.

The single chip microcomputer controller drives the plugging mechanism to stop and enable the plugging mechanism 725 to return to normal state after plugging cleaning work for a preset period of time. Of course, the built-in logic of the singlechip controller can also be other control logics such as working time for controlling blockage cleaning work according to the difference value of the concentration information of the machine washing liquid in the concentration information and the concentration information of the preset machine washing liquid in the preset concentration information when the opening time of the electromagnetic valve in unit time reaches the maximum value, and the built-in logic is not developed one by one.

Further, since the filter screen 7213 is embedded into the clamping groove 7214 from top to bottom, when the anti-blocking mechanism 725 performs blocking cleaning, the filter screen 7213 is subjected to a bottom-up flushing force, and is easily separated from the clamping groove 7214 from bottom to top under the flushing force, so that the subsequent filtering work of normally receiving the block solid-state machine washing liquid is affected. Therefore, three annular clamping blocks 72131 are arranged on the edge of the filter screen 7213, the outer edges of the three clamping blocks 72131 are circular arcs matched with the inner edges of the clamping grooves 7214, the top of the clamping groove 7214 is provided with an annular clamping edge 7215 matched with the outer edges of the filter screen 7213, three yielding grooves 72151 corresponding to the clamping blocks 72131 one by one are formed in the clamping edge 7215, when the filter screen 7213 is installed in the clamping groove 7214, the clamping blocks 72131 are aligned with the yielding grooves 72151 so that the filter screen 7213 is embedded into the clamping groove 7214, then the filter screen 7213 is horizontally rotated so that the clamping blocks 72131 are staggered with the yielding grooves 72151, and therefore the clamping edge 7215 and the clamping grooves 7214 form a limiting structure for the vertical direction of the clamping blocks 72131, and the filter screen 7213 is prevented from being separated from the clamping groove 7214 from the scouring force from bottom to top so as to influence the subsequent filtering work of normally carrying the block-shaped solid machine washing liquid.

The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
