Description

Technical Field

[0001] The present invention and the technical field of dishwashers particularly relate to a method for placing cleaning consumables in a dishwasher and a dishwasher. Background Art

[0002] As a kind of household appliance that frees up manpower, a dishwasher can wash dishes on behalf of users. People only need to place the dishes to be washed into the washing cavity of the dishwasher, and add cleaning consumables such as detergent or rinse agent into the dishwasher, and the dishwasher can automatically complete the washing process.

[0003] In the prior art dishwasher, the user needs to decide the amount of cleaning consumables to be added according to the degree of dirtiness of the dishes. In actual operation, the amount of cleaning consumables added is often incorrect, resulting in excessive amount of cleaning consumables causing residues, or too little amount of cleaning consumables causing incomplete cleaning. More importantly, the amount of cleaning consumables added in this dishwasher needs to be determined by the user, which greatly reduces the user experience.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a method for dispensing cleaning consumables into a dishwasher and a dishwasher to solve the shortcomings of the prior art. Summary of the invention

[0005] The first object of the present invention is to avoid the shortcomings of the prior art and provide a method for adding cleaning consumables to a dishwasher. The method can automatically obtain the amount of cleaning consumables added, thereby greatly improving the intelligence of the dishwasher.

[0006] The above-mentioned purpose of the present invention is achieved by the following technical measures:

[0007] A method for feeding cleaning consumables into a dishwasher is provided, which obtains dirtiness parameters of tableware inside the dishwasher, and controls a cleaning consumable feeding module to add cleaning consumables according to the dirtiness parameters. The feeding method can automatically obtain the amount of cleaning consumables added, thereby greatly improving the intelligence of the dishwasher.

[0008] Included are:

[0009] Step 1: After adding tableware, washing water is introduced and the washing water is tested to obtain initial dirtiness parameters;

[0010] Step 2: The cleaning consumables feeding module feeds the cleaning consumables for the first time to obtain an intermediate dirtiness parameter, and the initial dirtiness parameter obtained in step 1 and the intermediate dirtiness parameter obtained in step 2 are processed to obtain a replenishment amount of the cleaning consumables;

[0011] Step 3: The cleaning consumables feeding module adds cleaning consumables according to the cleaning consumables replenishment amount obtained in step 2, and starts dishwashing.

[0012] Preferably, the above step 2 includes:

[0013] Step 2.1, the cleaning consumables injection module injects an initial amount of cleaning consumables into the cleaning water and starts timing;

[0014] Step 2.2, after the time reaches the set time, detect the intermediate dirtiness parameter of the cleaning water;

[0015] Step 2.3, processing the initial dirtiness parameter obtained in step 1 and the intermediate dirtiness parameter obtained in step 2 to obtain a dirtiness variation coefficient;

[0016] Step 2.4: Compare the dirt variation coefficient obtained in step 2.3 with the cleaning consumables replenishment curve to obtain the cleaning consumables replenishment amount.

[0017] The role of the above step 2 is to finally obtain the amount of cleaning consumables to be added by processing the initial dirtiness parameters and the intermediate dirtiness parameters.

[0018] Preferably, the above step 2.1 specifically includes the cleaning consumables injection module injecting an initial amount of cleaning consumables into the cleaning water, and starting the timing, while spraying the tableware through the spray arm of the dishwasher. In step 2.1, spraying the tableware through the spray arm of the dishwasher can increase the speed of releasing dirt from the tableware, thereby obtaining a more accurate intermediate dirt parameter.

[0019] Preferably, in step 2.3 above, the dirt variation coefficient θ is obtained by formula (I),

[0020] θ=(α-β) / t Formula (I),

[0021] Wherein, α is the intermediate dirt parameter, β is the initial dirt parameter, t is the set time, and t>0 seconds. The release rate of dirt is obtained by formula (I), thereby confirming the degree of dirt on the surface of the tableware.

[0022] Preferably, the above step one is specifically to add the tableware, introduce cleaning water, then heat it to temperature T, spray the tableware for Q minutes through the spray arm, and then detect the cleaning water to obtain the initial dirtiness parameter, and Q>0, T≥35°C. The effect of spraying accelerates the release rate of tableware dirt, thereby obtaining a more accurate initial dirtiness parameter.

[0023] The dishwasher cleaning consumables feeding method of the present invention pre-establishes a corresponding relationship between the cleaning consumables replenishment amount and the dirt variation coefficient, obtains a cleaning consumables replenishment curve, and can accurately obtain the cleaning consumables replenishment amount from the dirt variation coefficient through the cleaning consumables replenishment curve.

The quantitative dispensing of cleaning consumables is achieved through the specific structure of the cleaning consumables dispensing module.

[0026] Preferably, the liquid level detector is provided with a float and a Hall switch that move according to the liquid level of the cleaning consumables, the float and the Hall switch are magnetically connected, and the float is movably assembled inside the accommodating chamber. The liquid level of the cleaning consumables inside the accommodating chamber is measured by the float and the Hall switch, which has the advantage of high reliability.

[0045] The technical solution of the present invention is further described in conjunction with the following embodiments.

[0046] Example 1.

[0047] A method for placing dishwasher cleaning consumables, such as Figure 1 As shown, the dirt parameters of the tableware inside the dishwasher are obtained, and the cleaning consumables feeding module is controlled to add cleaning consumables according to the dirt parameters.

[0048] The method for placing dishwasher cleaning consumables of the present invention comprises:

[0049] Step 1: After adding tableware, washing water is introduced and the washing water is tested to obtain initial dirtiness parameters;

[0050] Step 2: The cleaning consumables feeding module feeds the cleaning consumables for the first time to obtain an intermediate dirtiness parameter, and the initial dirtiness parameter obtained in step 1 and the intermediate dirtiness parameter obtained in step 2 are processed to obtain a replenishment amount of the cleaning consumables;

[0051] Step 3: The cleaning consumables feeding module adds cleaning consumables according to the cleaning consumables replenishment amount obtained in step 2, and starts dishwashing.

[0052] Step 2 includes:

[0053] Step 2.1, the cleaning consumables injection module injects an initial amount of cleaning consumables into the cleaning water and starts timing;

[0054] Step 2.2, after the time reaches the set time, detect the intermediate dirtiness parameter of the cleaning water;

[0055] Step 2.3, processing the initial dirtiness parameter obtained in step 1 and the intermediate dirtiness parameter obtained in step 2 to obtain a dirtiness variation coefficient;

[0056] Step 2.4: Compare the dirt variation coefficient obtained in step 2.3 with the cleaning consumables replenishment curve to obtain the cleaning consumables replenishment amount.

[0057] It should be noted that the amount of cleaning consumables to be added in the present invention is confirmed based on the initial dirtiness parameters and the intermediate dirtiness parameters. In fact, a small amount of initial cleaning consumables is added at the beginning. These initial cleaning consumables are usually only 5% to 10% of the total amount of cleaning consumables when the tableware is normally cleaned. After the initial amount is added, because the washing water is in a clean state, the tableware dirt during this period will be quickly released into the washing water. This release rate is proportional to the degree of dirtiness on the surface of the tableware. Therefore, the present invention indirectly confirms the degree of dirtiness on the surface of the tableware through the speed at which the dirt is released into the washing water.

[0058] Experiments have shown that if the initial amount of cleaning consumables is not added, but only the degree of dirtiness of the cleaning water is directly detected after the cleaning water is added, and the total amount of cleaning consumables added is obtained based on the dirtiness parameters of the cleaning water, it will cause the defect of misjudgment. Because most of the dirt is grease, it is difficult to release from the surface of tableware, and the cleaning water is also easily saturated with grease. For example, the dirtiness parameters of the cleaning water are often the same when a small amount of dirt is attached to the surface of the tableware compared to a large amount of dirt. Therefore, the method of adding cleaning consumables to the dishwasher of the present invention can greatly improve the accuracy of judging the degree of dirtiness.

[0059] Among them, step 2.1 specifically includes that the cleaning consumables feeding module will feed an initial amount of cleaning consumables into the cleaning water, and start timing, while spraying the tableware through the spray arm of the dishwasher.

[0060] In step 2.3 of the present invention, the dirt variation coefficient θ is obtained by formula (I),

[0061] θ=(α-β) / t Formula (I),

[0062] Among them, α is the intermediate dirt parameter, β is the initial dirt parameter, t is the set time, and t>0 seconds. In the actual operation process, the value range of t is 5 seconds to 60 seconds.

[0063] Step 1 of the present invention is to add tableware, introduce washing water, and then heat it to temperature T, spray the tableware for Q minutes through the spray arm, and then detect the washing water to obtain initial dirt parameters, and Q>0, T≥35°C. In this embodiment, Q is specifically 2 minutes and T is 40°C.

[0064] It should be noted that the purpose of the present invention of heating the washing water to T is to ensure the accuracy of the initial dirt parameter even at different air temperatures, and the spraying effect accelerates the release rate of tableware dirt, thereby obtaining a more accurate initial dirt parameter.

[0065] The present invention pre-establishes a corresponding relationship between the amount of cleaning consumables added and the dirt variation coefficient to obtain a cleaning consumables addition curve.

[0066] The dirt parameter of the present invention is turbidity value, absorbance or conductivity. In this embodiment, the dirt parameter is specifically turbidity value.

[0067] It should be noted that the turbidity value of the present invention can be obtained by installing a turbidity meter, an absorbance detector or a conductivity meter inside the dishwasher to detect the dirtiness parameter. The testing methods of these turbidity meters, absorbance detectors or conductivity meters are common knowledge, and those skilled in the art should know them, so they will not be described one by one here.

[0068] A method for adding cleaning consumables to a dishwasher can automatically detect dirt parameters of tableware and obtain the required amount of cleaning consumables according to the dirt parameters. The user does not need to manually add cleaning consumables based on experience, so that the cleaning consumables can be added accurately, ensuring the cleaning effect of the tableware while avoiding cleaning consumable residues, and greatly improving the intelligence of the dishwasher.

[0069] Example 2.

[0070] A method for placing dishwasher cleaning consumables, such as Figures 2 to 8 As shown, the cleaning consumables feeding module is provided with a chamber 110 for accommodating cleaning consumables, a quantitative feeder 200 for automatically and quantitatively extracting the cleaning consumables from the chamber 110 and feeding the cleaning consumables, and a liquid level detector 300 for indicating the height of the cleaning consumables liquid level. The chamber 110 is connected to the quantitative feeder 200, and the liquid level detector 300 is arranged in the chamber.

[0071] It should be noted that the quantitative dispenser 200 of the present invention can automatically and quantitatively extract the cleaning consumables from the accommodating chamber 110, based on the control of the external controller to start the quantitative dispenser 200 at the corresponding time of cleaning, so as to extract the cleaning consumables from the accommodating chamber 110. The quantitative extraction principle of the quantitative dispenser 200 means that the quantitative dispenser 200 can accurately control the amount of cleaning consumables extracted, thereby achieving quantitative control. The quantitative dispenser 200 of the present invention is a peristaltic pump, and the quantitative dispenser 200 can also be a metering pump or a gear pump. These pump bodies can realize the precise extraction of fluids, so that they can be used as the quantitative dispenser 200 of the present invention.

[0072] It should be noted that the present invention may also have one or more accommodating chambers 110. When there are multiple accommodating chambers 110, there may be multiple corresponding quantitative dispensers 200, or there may be only one quantitative dispenser 200. When there are multiple quantitative dispensers 200 and accommodating chambers 110, the accommodating chambers 110 and the quantitative dispensers 200 are connected one by one. When there is only one quantitative dispenser 200, the quantitative dispenser 200 is composed of a pump body and a switch for switching the passage between the accommodating chamber and the pump body, and the multiple accommodating chambers 110 are connected to the switcher pipeline, and the switcher is connected to the pump body pipeline. The switcher is an electronic phase-changing valve, a solenoid valve or a switching valve.

[0073] In this embodiment, only one containing chamber 110 and one quantitative dispensing device 200 are provided. The quantitative dispensing device 200 of this embodiment is specifically a peristaltic pump.

[0074] The liquid level detector 300 is provided with a float 310 and a Hall switch (not shown in the figure) that move according to the liquid level of the cleaning consumables. The float 310 and the Hall switch are magnetically connected, and the float 310 is movably assembled inside the accommodation chamber 110. The density of the float 310 is less than the density of the cleaning consumables, so that the float 310 can float on the liquid surface.

[0075] It should be noted that the working principle of the liquid level detector 300 is that the float 310 moves up and down with the liquid level of the cleaning consumables. When the cleaning consumables in the containing chamber 110 are basically used up, the magnetic block in the float 310 corresponds to the position of the detection end of the Hall switch, so that the magnetic force generated by the Hall switch and the magnetic block will trigger the Hall switch and generate an action signal. Then, the external controller receives the action signal and generates a warning signal to prompt the user to add cleaning consumables.

[0076] It should be noted that the position correspondence of the present invention means that when the float 310 moves to the position of the detection end of the Hall switch along with the detection of the liquid level of the cleaning consumables, and the magnetic field generated by the float 310 can trigger the detection end to open or close, it is called position correspondence.

[0077] The liquid level detector 300 of the present invention is composed of a float 310 and a Hall switch. Multiple experimental results have shown that the liquid level detector 300 of the present invention is more reliable and has a longer service life than other types of liquid level detectors 300 in the prior art.

[0078] The cleaning consumables dispensing device for a dishwasher is also provided with a housing 100, the space inside the housing 100 constitutes a accommodating chamber 110 and a fixed cavity 120 for accommodating a quantitative dispenser 200, and the accommodating chamber 110 is connected to the quantitative dispenser 200 through a pipeline. The housing 100 is used to seal the accommodating chamber 110 and provide a fixed basis for the quantitative dispenser 200. The Hall switch is embedded on the outside of the housing 100, and the quantitative dispenser 200 is fixedly assembled in the fixed cavity 120, so that the Hall switch does not contact the inside of the housing, and the isolation of the Hall switch from the cleaning consumables is achieved.

[0079] The housing 100 is provided with a positioning groove 140 for limiting the movement area of ​​the floating block 310 and an assembly cavity 130 matching the Hall switch, and the assembly cavity 130 is not connected to the accommodating chamber 110, the floating block 310 is movably assembled inside the positioning groove 140, the assembly cavity 130 is recessed in the accommodating chamber 110, and the Hall switch is assembled in the assembly cavity, such as Figures 3 to 5 .

[0080] It should be noted that the function of the positioning groove 140 of the present invention is to limit the movement area of ​​the float 310, prevent the float 310 from shifting, and improve the reliability of the liquid level detector 300, while the function of the assembly cavity 130 is to assemble the Hall switch, and make the Hall switch sense with the float 310, and ensure that the Hall switch will not contact with the cleaning consumables, thereby extending the life of the Hall switch.

[0081] When the automatic dispensing device is installed on the dishwasher and the dishwasher is in operation, the horizontal plane is defined as the bottom.

[0082] A first stop bar 141 is disposed above the positioning groove 140 to prevent the floating block 310 from being separated. The top and bottom of the positioning groove 140 are both connected to the accommodation chamber 110. The distance between the bottom of the positioning groove 140 and the bottom of the accommodation chamber 110 is less than or equal to 50% of the length of the floating block 310. The first stop bar 141 and the distance between the bottom of the positioning groove 140 and the bottom of the accommodation chamber 110 ensure that the pressure in the positioning groove 140 and the accommodation chamber 110 is equal, thereby maintaining the same height of the cleaning consumable liquid level in the positioning groove 140 and the accommodation chamber 110. At the same time, the first stop bar 141 can also prevent the floating block 310 from being separated.

[0083] It should be noted that the distance between the bottom of the positioning groove 140 and the bottom of the accommodating chamber 110 is less than or equal to 50% of the length of the floating block 310 , which can prevent the floating block 310 from moving out of the positioning groove 140 after the cleaning consumables are used up.

[0084] The float 310 is provided with a magnet and a housing 320 for driving the magnet to move up and down following the level of the cleaning consumables, and the magnet is sealed and assembled inside the housing 320. When the float 310 is located at the lowest point of the accommodation chamber 110, the position of the magnet corresponds to the detection end of the Hall switch.

[0085] It should be noted that the function of the housing 320 of the present invention is to protect the magnetic block and drive the magnetic block to float.

[0086] The surface of the housing 320 of the present invention is provided with abutting ribs 330 for reducing friction with the positioning groove 140. The housing 320 is also provided with a protrusion 340 for preventing tilting, and the protrusion 340 is integrally connected to the lower end of the abutting rib 330. The upper bottom surface of the protrusion 340 is provided with a transition structure surface 341.

[0087] When the float 310 moves up and down inside the positioning groove 140, the protrusion 340 can reduce the gap between the float 310 and the positioning groove 140, thereby preventing the float 310 from being seriously tilted inside the positioning groove 140, thereby avoiding unsmooth up and down movement. When the liquid level of the cleaning consumables is too low, and the liquid level of the cleaning consumables is lower than the lower bottom surface of the positioning groove 140, the lower end of the protrusion 340 moves to the outside of the positioning groove 140, and the protrusion 340 is located outside the positioning groove 140. At this time, the function of the transition structure surface 341 is to prevent the protrusion 340 and the positioning groove 140 from colliding with each other during the upward movement of the float 310 after the cleaning consumables are added again, so as to ensure that the float 310 as a whole smoothly enters the interior of the positioning groove 140.

[0088] The method of using the automatic dispensing device of the present invention is as follows: the user adds the cleaning consumables into the accommodating chamber 110 through the liquid filling port provided in the housing 100, and then seals the liquid filling port. When the dishwasher needs to add cleaning consumables, the quantitative dispenser 200 automatically and quantitatively extracts the corresponding amount of cleaning consumables from the accommodating chamber 110 according to the amount required each time. When the cleaning consumables in the accommodating chamber 110 are less than the alarm liquid level, the liquid level detector 300 sends a warning signal and prompts the user.

[0089] The liquid level detection structure can detect the liquid level of the cleaning consumables through the float 200 and the Hall switch, and the Hall switch does not contact the cleaning consumables, so the liquid level detection structure of the present invention has high reliability and long service life.

[0090] The method for dispensing cleaning consumables for a dishwasher of the present invention ensures quantitative dispensing of cleaning consumables through a cleaning consumable dispensing module.

[0091] Example 3.

[0092] A dishwasher adopts the method for placing dishwasher cleaning consumables as in embodiment 1 or 2. The method for placing dishwasher cleaning consumables is fixedly mounted on the door of the dishwasher.

[0093] The dishwasher can automatically detect the dirt parameters of tableware and obtain the required amount of cleaning consumables based on the dirt parameters. There is no need for users to manually add cleaning consumables based on experience. Cleaning consumables can be added accurately to ensure the cleaning effect of the tableware while avoiding residual cleaning consumables. It can also greatly improve the intelligence of the dishwasher.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
