In an embodiment of the present invention, as shown in fig. 1 to 8, the dishwasher 1 includes: the device comprises a case 20, a slag-isolating oil filter 10, a pipeline and a drain valve, wherein the case 20 is provided with a water pump 21 and a bowl washing groove 22 with an open top; the slag-separating oil filter 10 is arranged at the bottom of the case 20, the slag-separating oil filter 10 comprises a case body 100, an oil collecting box 200 and a slag frame 800, the case body 100 is provided with a water inlet 110 and a water outlet 120, and the slag frame 800 is arranged corresponding to the water inlet 110; the oil collecting box 200 is arranged in the box body 100, the top of the oil collecting box 200 is provided with an oil inlet 250 for grease to flow in, the oil collecting box 200 is provided with an oil drain valve 260, the water inlet flow of the water inlet 110 is larger than the water outlet flow of the water outlet 120, so that the liquid level in the box body 100 rises, and the grease on the upper layer of the liquid level flows into the oil collecting box 200; a tank 100 in communication with the bowl washer 22, the water pump 21 and the residue-proof oil filter 10; the drain valve is located on the pipeline between the bowl washing tank 22 and the box body 100, and the drain valve is used for controlling the dish washing water in the bowl washing tank 22 to flow into the box body 100, and when the drain valve is opened, the dish washing water can flow into the box body 100 from the bowl washing tank 22.

The dishwasher 1 provided by the invention can filter food residues in the dishwashing water and retain grease in the dishwashing water in the oil collecting box 200, so that the filtered dishwashing water is conveyed to the dishwashing tank 22 through the water pump 21 for dishwashing again. Wherein, the structure of the machine case 20 is similar to that of the dishwasher 1, and the main function is to provide a dish washing groove 22 for washing dishes; the residue-separating oil filter 10 has the function of filtering food residues and grease; the water pump 21 functions to pump the dishwashing water filtered by the residue-proof oil filter 10 into the dishwashing tank 22.

In particular, the operation of the dishwasher 1 of the present invention will now be described.

Step 1: and (4) washing dishes by ultrasonic waves. Firstly, water is injected into the dish washing groove 22 of the machine case 20, the machine case 20 operates the dish washing function, and dishes, chopsticks and other tableware in the dish washing groove 22 are cleaned;

step 2: and (5) filtering the residue of the dishwashing liquid to remove oil. (1) The ultrasonic dish washing function is closed, the drain valve is opened, the wastewater in the dish washing groove 22 flows into the tank body through the pipeline, and then flows into the slag frame 800 of the slag separation oil filter 10 from the water inlet 110 of the slag separation oil filter 10, the food residues are remained in the slag frame 800, and the filtered dish washing water flows into the tank body 100 of the slag separation oil filter 10; (2) because the water inlet flow of the water inlet 110 is larger than the water outlet flow of the water outlet, the liquid level in the box body 100 rises continuously, and because the density of the grease is lower than that of water, the grease floats on the upper layer of the liquid level, and the grease on the upper layer of the liquid level flows into the oil collecting box 200; (3) when the liquid level of the grease rises to be higher than the side wall of the oil collecting box 200, the upper layer of grease flows into the oil collecting box 200 of the slag-separating oil filter 10, the grease on the upper layer of the water surface continuously flows into the oil collecting box 200 along with the continuous rising of the water surface in the box body 100, the liquid level of the grease in the oil collecting box 200 gradually rises, and when the grease amount in the oil collecting box 200 reaches a certain degree, a worker discharges the grease in the oil collecting box 200;

and step 3: pumping the dishwashing water after removing the oil from the filter residues to the dishwashing tank 22. The dish washing water after filtering food residues and grease through the residue separation oil filter 10 can flow back to the dish washing groove 22 for washing dishes through the pumping action of the water pump 21, so that the recycling of the dish washing water can be realized, the water consumption of the dish washing machine 1 is reduced, and the utilization efficiency of the dish washing water is improved.

It should be emphasized here that when the liquid level of the grease layer is higher than the oil inlet 250 of the oil collecting box 200, the grease flows into the oil collecting box 200 through the oil inlet 250, and considering that a small amount of water is mixed in the grease flowing into the oil collecting box 200, the grease mixed with the small amount of water can be still and separated again in the oil collecting box 200, so that the separation degree of the grease and the water can be improved, the separated water layer automatically flows out through the water outlet 120, and the separated grease layer is discharged through the oil discharge valve 260 by the worker, so that the working time of the worker in the oil discharging process can be saved, and the working efficiency of the worker can be improved.

Further, in order to make the staff can conveniently open water pump 21, realize the recycle of the water that washes the dishes, in this embodiment, dish washer still includes control panel 30, control panel 30 locates on quick-witted case 20, is equipped with water cyclic utilization key 31 on control panel 30, and water cyclic utilization key 31 is arranged in controlling water pump 21 to pump the water that washes the dishes that delivery port 120 flows to bowl washing groove 22, the drain valve is closed.

It should be noted that when the recycling key 31 is pressed by the operator, the drain valve is in a closed state, so that the dishwashing water in the dishwashing tub is prevented from flowing into the water tank. Specifically, if the drain valve is already in the closed state when the worker presses the recycling key 31, the drain valve remains closed; if the operator presses the recycle key 31, the drain valve is in an open state, and the drain valve is switched to a closed state.

Further, referring to fig. 4 and 5, in consideration of the risk that the worker cannot observe the thickness of the grease layer in the oil collecting box 200 in time, in this embodiment, the slag and oil separator 10 further includes an oil layer thickness sensor 300 and a prompting device, the oil layer thickness sensor 300 is used for detecting the thickness of the grease layer in the oil collecting box 200, and the prompting device is activated when the grease layer reaches a preset thickness. Specifically, the oil-out prompting signal includes an audio prompting signal or a light prompting signal, and accordingly, the prompting device can be the alarm lamp 330, the buzzer, or a combination thereof. Thus, after the oil layer thickness sensor 300 detects that the grease in the oil collecting box 200 reaches a certain thickness, that is, the grease amount in the oil collecting box 200 can reach a certain amount, the reminding device informs the staff to clean the oil collecting box 200. In this way, the grease in the oil collecting box 200 can be prevented from being accumulated too much, so that the grease flows out from the second drainage pipe 600 or flows into the box body 100; frequent cleaning of the oil collection box 200 to avoid excessive grease build up due to unknown grease levels in the oil collection box 200 can also be avoided.

Further, in order to facilitate that the worker can timely remove the oil drainage alarm of the reminding device when finishing the oil drainage work, in this embodiment, the control panel 30 is further provided with an oil drainage alarm removing key 32 for closing the reminding device, and the oil drainage alarm removing key 32 is in signal connection with the reminding device.

Specifically, the structure and operation of the reservoir thickness sensor 300 will now be described in detail. The oil layer thickness sensor 300 comprises a floating ball device 310 and a conductive sensor 320, wherein the floating ball device 310 is used for detecting the upper liquid level of the oil layer, and the conductive sensor 320 is used for detecting the lower liquid level of the oil layer. Because the density of the floating ball is less than that of the grease, the floating ball device 310 can float on the grease layer, and the upper liquid level of the grease layer can be detected through the floating ball device 310; because the grease in the oil collecting box 200 contains a small amount of water, the water is at the bottom layer initially, the grease is at the upper layer, and the grease layer is firstly contacted with the conductive sensor 320 along with the rising of the grease liquid level in the oil collecting box 200, and at the moment, the conductive sensor 320 is not conductive. However, the height of the liquid level in the oil collecting box is smaller, and the floating ball device does not detect that the liquid in the oil collecting box reaches the preset liquid level, so that the thickness of the grease in the collecting box is judged to be not larger than the preset thickness. In this embodiment, the floating ball device 310 detects whether the liquid level in the oil collecting box 200 reaches a predetermined thickness, which is the highest liquid level thickness of the oil collecting box 200, and when the liquid level in the oil collecting box 200 is higher than the liquid level thickness, the liquid at the bottom of the oil collecting box 200 is drained through the second drainage pipe 600. As the liquid such as grease and the like continuously flows into the oil collecting box 300, the liquid level in the oil collecting box 300 continuously rises, the floating ball device 310 detects that the liquid level in the oil collecting box 300 reaches the preset liquid level, that is, the liquid level of the upper layer of the grease layer reaches the preset height, but at this time, the liquid level of the lower layer of the grease layer may be located above the conductive sensor 320, and the thickness of the grease in the oil collecting box 200 becomes thicker and thicker as more and more grease in the box 100 enters the oil collecting box 200. Due to the second drain pipe 600, the liquid level in the oil collecting box 200 reaches the preset height and cannot rise continuously, that is, the liquid level of the upper layer of the grease layer cannot rise, and the liquid level of the lower layer of the grease layer can move downwards. The lower level of the layer of grease reaches the conductive sensor 320, and the conductive sensor 320 is located in the grease, and the conductive sensor 320 detects that the liquid at its location is not conductive. That is, it means that the grease layer reaches a predetermined thickness by both the floating ball device 310 and the conductive sensor 320. In this way, when the floating ball device 310 detects that the liquid level of the liquid in the oil collecting box 320 is at the preset height and the conductive sensor 320 detects that the liquid is not conductive, the reminding device is started.

Further, with continued reference to fig. 4, the installation structure of the floating ball device 310 will now be described. In this embodiment, the floating ball device 310 includes a floating ball 311 and a guide rod 312 extending upward from the top of the floating ball 311, the top of the inner wall of the oil collecting box 200 is fixedly provided with a limiting member 270, the limiting member 270 is provided with a limiting hole penetrating in the up-down direction, and the guide rod 312 penetrates through the limiting hole.

Thus, when the floating ball 311 floats up and down along with the change of the liquid level in the oil collecting box 200, the floating ball 311 drives the guide rod 312 to move up and down, and the limiting part 270 has a limiting effect on the guide rod 312, so that the floating ball 311 device 310 can be ensured to keep stable movement in the up-and-down direction, and the accuracy of detecting the liquid level of the grease by the floating ball 311 device 310 can be ensured.

It should be noted that, because the guide rod 312 is fixedly arranged at the top of the floating ball 311, the bottom of the floating ball 311 can contact with the bottom of the oil collecting tank, and therefore the floating ball 311 can measure the level of the grease with a lower height; in addition, when the floating ball 311 moves upward to abut against the stopper 270, the grease in the oil collecting box 200 reaches the maximum level.

Further, referring to fig. 4 and 5, in order to avoid the solidification of the grease in the oil collecting box 200 and ensure the fluidity of the grease in the oil collecting box 200, in this embodiment, the slag trap 10 further includes a first heating device 400, the first heating device 400 is in signal connection with the floating ball device 400, and when the liquid level in the oil collecting box 200 reaches a preset liquid level, the first heating device 400 is activated. In this embodiment, the first heating device 400 is an electric heating pipe disposed in the oil collecting box 200, so that when the liquid level in the oil collecting box 200 reaches a preset liquid level, the first heating device 400 starts heating, and the grease in the oil collecting box 200 is prevented from solidifying, which results in that the liquid (including water, grease, etc.) in the box body 100 cannot enter the oil collecting box 200. Meanwhile, the grease is ensured to have better fluidity, so that the grease can be conveniently discharged by workers.

Preferably, referring to fig. 1, fig. 2, fig. 4 and fig. 5, in order to enable a worker to actively heat grease in the oil collecting box 200 according to actual needs, in this embodiment, an oil temperature control key 33 is further disposed on the control panel 30, and the oil temperature control key 33 is used for controlling the first heating device 400 to be turned on or turned off. Like this, when the oil reservoir thickness does not reach preset thickness, but the mobility of the interior grease of oil collecting box 200 is relatively poor, the staff can open first heating device 400 through oil temperature control key 33, and then can heat the grease layer in oil collecting box 200, improves the mobility of grease layer. Meanwhile, when the oil in the oil collecting box 200 reaches a predetermined amount and needs to be cleaned, the worker may turn off the first heating device 400 which is working at this time. The oil temperature control key 33 can also control the power of the first heating device 400, so that the temperature of the oil in the oil collecting box 200 can be controlled.

Further, referring to fig. 1 and 2, a power switch key 23 is arranged on the case, and when the power switch key 23 is turned on, the drain valve is closed. Specifically, the power switch 23 is used to control the dishwasher 1 to start or close, and when the power switch 23 is turned on, the dishwasher is to be operated, so as to prevent the washing water in the tub from flowing away, and therefore the drain valve needs to be kept in a closed state. It should be noted that, if the power switch 23 is turned on, and the drain valve is already in the closed state, the drain valve remains closed; if the power switch key 23 is turned on, the drain valve is in an open state, and the drain valve is switched to a closed state. The dishwasher 1 is to be operated, which means that when the water circulation utilization key 31, the oil temperature control key 22 and the like are started, the dishwasher 1 can enter corresponding functions.

Specifically, after the worker goes to work, the worker turns on the power switch button 23, and the dishwasher 1 automatically injects water into the bowl washing tub 22 up to a required amount of water. Further, a structure of the dishwasher 1 is now described, in this embodiment, the dishwasher 1 is an ultrasonic dishwasher, the control panel 30 is further provided with an ultrasonic cleaning key 34 and a drain key 35 for turning on or off an ultrasonic dish washing function, and when a worker turns on the ultrasonic cleaning key 34, the dishwasher 1 operates the ultrasonic dish washing function; the bowl washing groove 22 is communicated with a drain valve, the drain key 35 is used for controlling the drain valve to drain water, and when the drain key 35 is opened by a worker, the bowl washing water in the bowl washing groove 22 is drained by the bowl washing machine 1, so that the bowl washing water enters the box body 100.

Further, in order to control the dish washing water in the bowl washing tank 22 to flow to the tank 100 when the drain valve is damaged, considering that the drain valve may be damaged, in this embodiment, a drain hole (not shown) is disposed at the bottom of the bowl washing tank 22, and a drain plug (not shown) for opening or closing the drain hole is disposed on the drain hole. Thus, when the drain valve is damaged and cannot be opened, the worker can pull out the drain plug and open the drain hole to drain, so that the dish washing water in the dish washing groove 22 can flow into the box body 100.

As a preferable mode, the control panel 30 is further provided with a water temperature control key 36, and the second heating device is used for heating the dishwashing water in the dishwashing tank so as to better remove oil stains on the tableware; dishwasher 1 further includes a second heating device, and water temperature control key 36 is used for controlling the opening or closing of the second heating device, and the second heating device is used for controlling the water temperature in bowl washing trough 22, so that the temperature of the water washed in bowl washing trough 22 can be conveniently maintained, and the dish washing effect can be improved. The water temperature control key 36 is capable of controlling the power of the second heating means in order to regulate the temperature of the water in the bowl washing tub 22.

In particular, the operating steps of the dishwasher 1 are as follows, step 1: turning on a power switch key 23, and starting to inject water into the bowl washing groove 22; step 2: after the required water amount is reached, the ultrasonic cleaning key 34 is opened to start the ultrasonic cleaning of the tableware such as bowls, dishes, chopsticks and the like in the bowl washing groove 22; and step 3: after the ultrasonic cleaning is finished, the drainage key 35 is opened, so that the dish washing water in the dish washing groove 22 enters the box body 100 of the residue-isolating oil filter 10, and the dish washing water is subjected to oil-water separation and residue filtration in the box body 100. And 4, step 4: the water recycling key 31 is opened, and the dish washing water of the box body 100 after oil removal and residue filtration flows back to the dish washing groove 22 through the water pump 21 for recycling, so that water resources can be saved, and the water consumption cost are reduced.

Further, as shown in fig. 6 and 7, in order to increase the amount of the recyclable dishwashing water, in the present embodiment, the oil collection box 200 has a volume greater than that of the box body 100, and thus, the box body 100 has a volume greater than that of the oil collection tank 200, and thus, the box body 100 has a volume large enough to increase the amount of the recyclable dishwashing water. In fig. 7, the oil collecting box 200 is arranged across the box 100, and the oil collecting box 200 is designed in the way of fig. 6, so that the water stored in the box 100 is obviously increased.

Specifically, in the present embodiment, the ratio of the volumes of the tank 100 and the oil sump 200 ranges from 3: 1 to 6: 1. in this way, the tank 100 has a larger volume than the sump 200, and thus, a larger amount of water can be stored, and the amount of the collected dishwashing water can be increased.

Further, referring to fig. 3 to 5, in order to facilitate the grease in the box 100 to flow into the oil collecting box 200, in this embodiment, the top of the box 100 has a grease gathering area which is contracted from bottom to top, and the oil inlet 250 of the oil collecting box 200 extends into the grease gathering area. When the liquid level in the box body 100 rises continuously and reaches the grease gathering area, the grease gathering area is arranged in a shrinkage shape from bottom to top, and the density of the grease is smaller than that of water, so that the thickness of the grease on the water can be increased. Thus, the more the liquid level of the grease moves upwards, the thicker the grease layer produced by the grease with the same volume is, so that the grease can conveniently flow into the oil collecting box 200 from the grease gathering area when the liquid level of the grease is higher than the oil inlet 250 of the oil collecting box 200.

Further, referring to fig. 3 and 4, the grease accumulation area will now be described in detail. The box 100 includes the diapire, from the lateral wall that the diapire periphery upwards extends and from the oil guide cover plate 130 of the top slope of lateral wall upwards extension, and the diapire and the lateral wall of box 100 enclose and close the water storage tank that forms splendid attire dish washing water, and the below of oil guide cover plate 130 forms grease and gathers the district.

A first drain pipe 500 is communicated with the inside of the box body 100, a second drain pipe 600 is communicated with the inside of the oil collecting box 200, and one end of the first drain pipe 500 and one end of the second drain pipe 600 are both communicated with the water outlet 120; the other end of the first drain pipe 500 faces the bottom of the tank 100, and the other end of the second drain pipe 600 faces the bottom of the tank 100; the first and second drain pipes 500 and 600 are lower than the oil inlet 250, and both the first and second drain pipes 500 and 600 are communicated with the outside atmosphere.

Wherein, it should be understood that one end of the first drain pipe 500 is used for liquid outflow and the other end of the first drain pipe 500 is used for liquid inflow; similarly, one end of the second drainage pipe 600 is used for liquid outflow, and the other end of the second drainage pipe 600 is used for liquid inflow. Thus, the liquid in the tank 100 can be left to the water outlet through the first drain pipe 500 and flow out of the tank 100, and the liquid in the oil collection box 200 can be left to the water outlet through the second drain pipe 600 and flow out of the oil collection box 200.

Meanwhile, it should be understood that the liquid entering the first drain pipe 500 is the liquid at the bottom of the middle tank 100, and specifically, when the liquid level of the tank 100 reaches the highest point of the first drain pipe 500, the liquid at the bottom of the tank 100 will flow upward along the first drain pipe 500 to the water outlet and flow out of the tank 100. Similarly, the liquid entering the second drainage pipe 600 is the liquid at the bottom of the oil collecting box 200, and specifically, when the liquid level of the oil collecting box 200 reaches the highest point of the second drainage pipe 600, the liquid at the bottom of the oil collecting box 200 will flow upward along the second drainage pipe 600 to the water outlet and flow out of the oil collecting box 200.

The operation of the lower slag trap 10 will now be explained in detail. After once washing the dishes, when not having water in box 100, the water that washes the dishes gets into box 100, and the water that washes the dishes like this gathers in will box 100, and box 100's liquid level rises, and the water that washes the dishes simultaneously carries out oil water separating in box 100 in step, and the grease floats on the upper strata of the water that washes the dishes, and the bottom of box 100 is the water after the separation grease, and the juncture between grease and water is oil water mixture certainly. It will also be appreciated that the grease floating above the water surface is relatively thin. As the bowl continues to fill, the liquid level in the tank 100 will continue to rise.

When the amount of the dish washing water is less, the liquid level in the box body 100 rises to a certain degree and does not rise, and the liquid level of the box body 100 does not reach the height of the first drain pipe 500 at the moment, so that the first drain pipe 500 cannot discharge the water at the bottom of the box body 100. The next time the dishwashing water is introduced into the tub 100, the liquid level in the tub 100 is then raised. When the amount of the dishwashing water is large, the liquid level in the cabinet 100 exceeds the height of the first drain pipe 500, so that the water at the bottom of the cabinet 100 flows out of the cabinet 100 through the outlet along the first drain pipe 500. However, since the flow rate from the water outlet 120 is less than the flow rate from the water inlet 110, the liquid level in the tank 100 will continue to rise until the liquid level in the tank 100 rises to the oil inlet 250, so that the grease can flow into the oil collecting box 200 from the oil inlet 250. As the water level in the tank 100 continues to rise, water in the tank 100 also enters the oil collecting box 200, and at this time, the oil collecting box 200 contains not only oil but also water, which has a density greater than that of the oil, and the water is located in the lower layer in the oil collecting box 200. At this time, it should be understood that the first drain pipe 500 is lower than the oil inlet 250, so that a large amount of water in the tank 100 is prevented from entering the oil collecting box 200. When the water in the oil collecting box 100 continuously enters the oil collecting box 200, the liquid level in the oil collecting box 200 continuously rises until the liquid level in the oil collecting box 200 is higher than the second water discharging pipe 600, so that the water at the bottom of the oil collecting box 200 can be discharged out of the oil collecting box 200 from the water outlet 120 through the second water discharging pipe 600, the liquid level in the oil collecting box 200 can be prevented from rising to the oil inlet 250, and the grease in the oil collecting box 200 can flow into the box 100 from the oil inlet 250. Of course, when the dishwashing water enters the water tank 100 next time, grease of the dishwashing water enters the oil collecting box 200 in the above-mentioned flow.

When the water in the tank body 100 enters the oil collecting box 200, the liquid level in the oil collecting box 200 is not higher than that in the second drain pipe 600, at this time, the second drain pipe 600 cannot discharge the liquid in the oil collecting box 200 outwards, and after the next dishwashing water enters the tank body 100, grease in the dishwashing water enters the oil collecting box 200.

At this time, it should be understood that the oil trap 200 can collect grease in the dishwashing water several times.

Wherein, the first drain pipe 500 and the second drain pipe 600 are both communicated with the outside atmosphere. In this embodiment, the slag trap 10 further includes a communicating pipe 700, the communicating pipe 700 has a first port, a second port and a third port, the first port is communicated with the first drain pipe 500, the second port is communicated with the second drain pipe 600, and the third port is communicated with the external atmosphere, so that the air pressure in the tank 100 is balanced with the external atmosphere. This prevents the first drain pipe 500 and the second drain pipe 600 from generating a siphon phenomenon to drain the liquid in the tank 100 and the liquid in the sump case 200.

The first drainage pipe 500 is 1mm to 10mm lower than the oil inlet 250; the second drain pipe 600 is 1mm to 10mm lower than the oil inlet 250. Thus, both the first drain pipe 500 and the second drain pipe 600 are just slightly lower than the oil inlet 250. Therefore, the collection of the dish washing water in the box body 100 is facilitated, the oil-water separation is sufficient, and the grease can enter the oil collecting box 200 more conveniently; and also contributes to the stratification of grease and water in the oil collecting box 200, and prevents the water discharged from the second water discharging pipe 600 from containing grease. Wherein, the first drain pipe 500 is lower than 2mm of the oil inlet 250, and the second drain pipe 600 is lower than 2mm of the oil inlet 250.

The first drain pipe 500 and the second drain pipe 600 are both disposed in an inverted U shape. Specifically, the first drainage pipe 500 includes a first connection section extending transversely, and a first water inlet section and a first water outlet section extending downwardly from two ends of the first connection section, respectively; the second water discharging pipe 600 includes a second connection section extending in a transverse direction, and a second water inlet section and a second water outlet section extending downward from both ends of the second connection section, respectively. It will be appreciated that water at the bottom of the housing 100 enters from the first water inlet section, flows up the first water inlet section, then flows along the first connecting section towards the first water outlet section, and finally flows down the first water outlet section to the water outlet 120. Similarly, the second drainage pipe 600 flows in the same manner.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
