The dishwasher that has the degerming disinfection function of selling on the existing market, this degerming disinfection function only realizes the degerming disinfection through heating the washing water to certain high temperature. Because the high-temperature sterilization is influenced by the temperature resistance of the tableware, the temperature is not particularly high in the actual high-temperature sterilization process, so that the effect of killing part of viruses with high temperature resistance is not ideal.

The water outlet valve 13 is arranged on the body 1, one end of the water outlet valve 13 is connected with the electrolysis device 5, and the other end is communicated with the inner container 3.

Therefore, the water inlet valve 6, the breather 14, the flow meter 15, the water softener 7 and the three-way valve 12 are sequentially communicated in series. When the inner container 3 needs to be filled with water, the water inlet valve 6, the respirator 14, the flow meter 15 and the water softener 7 are communicated with the three-way valve 12, the first water outlet of the three-way valve 12 is opened, and the second water outlet is closed, so that a first water inlet pipeline is formed.

Example 2

As shown in fig. 3, an embodiment of the present invention provides a sterilization control method applied to the dishwasher of any one of the above embodiments, the sterilization control method including:

s1, when the electrolysis device 5 is started, the concentration of harmful gas in the inner container 3 is obtained;

and S2, controlling the exhaust device to start when the current concentration of the harmful gas reaches a preset concentration.

In this embodiment, the concentration of the harmful gas in the inner container is obtained when the electrolysis apparatus is started. Because the electrolysis device generates a small amount of harmful gases such as hydrogen and chlorine during electrolysis, the content of the hydrogen and the chlorine in the dishwasher is increased after long-time electrolysis, so that the air pressure in the dishwasher is increased. And if the current concentration of the harmful gas reaches the preset concentration, controlling the exhaust device to start. After the air exhaust device is opened, the air exhaust device can discharge harmful gas in the dish washer outwards, so that the balance of air pressure in the dish washer and outside air pressure is ensured, and the dish washer can work normally. And the exhaust device can exhaust the gas with higher temperature in the inner container, thereby improving the cooling rate of the inner container of the dish washer.

S3, when the washing stage is finished, acquiring the temperature of the inner container 3/the electrolysis device 5;

the washing stage comprises a main washing stage and the cold bleaching stage. After the dishwasher completes washing the dishes 11, it is necessary to sterilize the dishes 11. The chemical property of sodium hypochlorite in the disinfectant is unstable and is greatly influenced by temperature. When the dishwasher washes the tableware 11, the temperature of the inner container 3 in the main washing stage is between 45 ℃ and 70 ℃ because the temperature of the washing water heated by the heater 10 is higher in the main washing stage. Because the arrangement position of the electrolytic device 5 is relatively close to the inner container 3, the higher temperature of the inner container 3 can be transferred to the electrolytic device 5 through heat transfer, and the temperature of the electrolytic device 5 is also higher. Since sodium hypochlorite in the disinfectant is stable in chemical properties at a temperature below 25 ℃, the disinfectant is not suitable for preparing the sodium hypochlorite disinfectant by the electrolysis device 5 at a temperature of 45-70 ℃.

Therefore, after the washing stage is finished, in order to ensure the stability of the chemical property of the sodium hypochlorite in the disinfectant, the dishwasher needs to be cooled down by cold rinsing to reduce the temperature of the inner container 3 to below 25 ℃. Since the temperature of the electrolytic device 5 can be lowered only by heat transfer of the inner container 3, cold bleaching can be performed many times in order to prevent the temperature of the inner container 3 and the temperature of the electrolytic device 5 from rebounding. At the end of the washing phase of the dishwasher, the temperature of the dishwasher liner 3 needs to be taken. I.e. at the end of the main wash phase and likewise at the end of the cold rinse phase.

S4, judging whether the temperature of the inner container 3/the electrolysis device 5 is lower than a preset temperature or not;

after the temperature of the inner container 3 of the dish washing machine or the temperature of the electrolytic device 5 is obtained, whether the temperature is higher than the preset temperature or not is judged, namely whether the temperature is higher than the stable temperature of sodium hypochlorite by 40 ℃.

And S5, when the temperature of the inner container 3 is lower than or equal to a preset temperature, controlling the electrolytic device 5 of the dish washing machine to start.

When the dishwasher detects that the temperature of the inner container 3 is equal to or lower than the preset temperature, the electrolytic device 5 of the dishwasher is controlled to start working, electrolyte is electrolyzed, and sterilized water is generated.

S6, when the temperature of the inner container 3 is higher than the preset temperature, controlling the dish-washing machine to enter a cold bleaching stage;

and when the temperature of the inner container 3 is higher than the preset temperature, controlling the dishwasher to enter a cold bleaching stage. In the cold bleaching stage, the dishwasher washes the dishes 11 in the inner tub 3 with cold water, while cooling the inner tub 3 with cold water.

Of course, if the temperature of the inner container 3 is obtained to be equal to or lower than the preset temperature due to natural cooling or low temperature of the washing water, the electrolytic device 5 of the dishwasher is directly controlled to start. The dishwasher is not required to be subjected to cold bleaching, namely, the steps S1, S2 and S3 are only required.

So set up, can be with inner bag 3/electrolytic device 5's temperature control below presetting the temperature, then produce sodium hypochlorite disinfectant through electrolytic device 5 electrolysis again to guarantee that sodium hypochlorite has comparatively stable chemical property under lower temperature, thereby promoted disinfectant's disinfection efficiency, promoted user's use and experienced.

Optionally, in some embodiments of the present invention, the above-mentioned cold bleaching stage may comprise a plurality of cold bleaching stages. Specifically, when the current cold bleaching stage is finished, whether the temperature of the inner container 3 is equal to or lower than a preset temperature is judged, and when the temperature of the inner container 3 is equal to or lower than the preset temperature, the electrolytic device 5 is controlled to be started. And when the detected temperature of the inner container 3 is still higher than the preset temperature, controlling the dishwasher to enter the next cold bleaching stage, continuously detecting the temperature of the inner container 3 when the cold bleaching stage is finished, controlling the electrolytic device 5 to start if the temperature is equal to or lower than the preset temperature, and repeating the steps if the temperature is still the preset temperature until the temperature of the inner container 3 is equal to or lower than the preset temperature.

According to the embodiment of the invention, the plurality of cold bleaching stages are arranged, so that the temperature rebound of the inner container 3 can be prevented after the inner container 3 is subjected to cold bleaching, the inner container 3 can be ensured to be stabilized at a lower temperature stage, and the stability of the chemical property of sodium hypochlorite is facilitated. Also, the number of times of cold bleaching is preferably not more than three, and after more than three times, the total time is long and water is wasted.

Optionally, in some embodiments of the invention, the main wash stage comprises:

s7, communicating a first water inlet pipeline between an external water source and the water inlet of the inner container 3, and feeding water into the inner container 3;

s8, when the water inflow of the inner container 3 reaches a first preset threshold value, starting the spraying device 4 to perform a main washing program; in the main washing process, the water introduced into the spray device 4 needs to be heated.

In the main washing stage, after the first water inlet pipeline is connected as described in embodiment 1, water may be introduced into the inner container 3. And when the water inflow of the inner container 3 reaches a first preset threshold value, starting the spraying device 4 to carry out a main washing program. At this time, as described in the above embodiment, after the heater 10 heats the water introduced into the shower unit 4, the shower unit 4 sprays hot water to wash the dishes 11 to be washed in the inner tub 3.

Optionally, in some embodiments of the invention, the cold bleaching stage comprises:

s9, when the main washing program is finished, discharging water in the inner container 3;

s10, after the water is drained, water is fed into the inner container 3; when the water inflow reaches a second preset threshold value, starting the spraying device 4 to carry out a cold bleaching procedure; when the cold bleaching procedure is carried out, cold water is directly introduced into the spraying device 4.

At the end of the main washing process, the washing water in the tub 3 is drained by the drain pump 8. After the washing water is discharged, water is again introduced into the inner tub 3 through the first water inlet pipe. And when the water inflow reaches a second preset threshold value, starting the spraying device 4 to carry out a cold bleaching procedure. As described in the above embodiments, when performing the cold bleaching, after the water enters the inner container 3, the washing pump 9 directly delivers the water to the spraying device 4 without heating by the heater 10, thereby achieving the purpose of the cold bleaching and reducing the temperature in the inner container 3 of the dishwasher.

Optionally, in some embodiments of the present invention, before the step of controlling the activation of the electrolyzer 5 of the dishwasher, the method further comprises:

as in the previous embodiment, the second water inlet line is connected to supply water to the electrolysis device 5.

In the embodiment of the invention, after the electrolysis device 5 for controlling the dishwasher is started, the method comprises the following steps:

s11, obtaining the electrolysis time of the electrolysis device 5;

s12, judging whether the electrolysis time reaches a preset time or not;

s13, controlling a dish-washing machine to introduce the sterilized water generated by the electrolysis device 5 into the inner container 3 after the electrolysis time reaches the preset time.

After the electrolysis device 5 is started, the electrolysis device 5 starts electrolysis of the electrolyte to generate sterilized water. The concentration of the sterilized water is higher as the electrolysis time of the electrolysis means 5 is longer, and therefore, the concentration of the sterilized water can be controlled by controlling the electrolysis time of the electrolysis means 5. Since the concentration of the sterilizing water is different in the different modes of the dishwasher, different electrolysis times are previously set.

After the electrolysis time is obtained, whether the electrolysis time reaches the preset time is judged, the preset time is the preset electrolysis time, and after the electrolysis time reaches the preset time, the concentration of the disinfectant water is indicated to reach the requirement on the concentration of the disinfectant water in the mode, so that the dishwasher can be controlled to introduce the disinfectant water generated by the electrolysis device 5 into the inner container 3.

The electrolysis time can be controlled between 10min and 40 min. Can furthest guarantee that the electrolyte in the electrolytic device 5 can be completely electrolyzed, thereby improving the concentration of the sterilized water and further improving the sterilization efficiency of the sterilized water.

Optionally, in some embodiments of the present invention, after step S11, the method may further include:

s14, controlling the dish washing machine to enter a disinfection stage;

s15, acquiring the disinfection time of the disinfection stage;

s16, judging whether the disinfection time reaches a preset disinfection time or not;

s17, controlling the dish washer to stop disinfecting after the disinfecting time reaches the preset disinfecting time.

And after controlling the dish-washing machine to introduce the sterilizing water generated by the electrolysis device 5 into the inner container 3, controlling the dish-washing machine to enter a sterilizing stage. The dishwasher introduces the sterilizing water into a washing system of the dishwasher, and the washing system sprays the sterilizing water to sterilize and wash the tableware 11 in the inner container 3.

Because the disinfection stage is preset with certain disinfection time, the disinfection time consumed in the disinfection stage needs to be acquired, whether the disinfection time reaches the preset disinfection time or not is judged, and the dish-washing machine is controlled to stop disinfection after the preset disinfection time is reached.

The disinfection time can be controlled between 20min and 60min, thus ensuring that the viruses possibly existing in the inner container 3 are completely killed, and ensuring the use safety of users.

After the dishwasher stops sterilizing, the sterilization control method further includes: controlling the dishwasher to enter a hot bleaching stage and a drying stage in sequence.
