Through carrying out research discovery to the dish washer structure among the prior art, the steam generator 4 of current dish washer is equipped with only a temperature controller and controls the heating temperature of steam generator 4 in the course of the work, but, the steam generator 4 all is powerful heating pipe that all adopts in the heating process at present, in case this only temperature controller is invalid, then causes the problem of steam generator 4 dry combustion method very easily, and this will bring huge hidden danger. Moreover, the heating operation of the steam generator 4 is controlled by a single temperature controller, and the steam temperature cannot be accurately adjusted.

For the above defects, the present application provides the following technical solutions.

As shown in fig. 1 and 2, the present embodiment provides a steam generator 4 including a housing 41; the steam generator 4 further comprises a heat generating component 42, the heat generating component 42 being disposed within the housing 41; the steam generator 4 further comprises a first temperature controller 43 and a second temperature controller 44, and both the first temperature controller 43 and the second temperature controller 44 are in control connection with the heat generating component 42; wherein, the trip temperature of the first temperature controller 43 is lower than the trip temperature of the second temperature controller 44. Therefore, during the operation of the steam generator 4, the first temperature controller 43 and the second temperature controller 44 are connected to the heat generating component 42 for temperature control, and when the first temperature controller 43 fails, the second temperature controller 44 still can control the temperature of the heat generating component 42, so that the steam generator 4 has dual temperature control guarantees during the operation.

In one embodiment, the first thermostat 43 is a recoverable thermostat. Meanwhile, the second thermostat 44 may be selected as an unrecoverable thermostat.

This enables the temperature of the steam generator 4 to be effectively controlled so that the steam generator 4 does not suffer from a drop in the temperature generated by the steam generator 4 due to component degradation.

The utility model also provides a dish washer, include steam generator 4. Since the detailed structure, functional principle and technical effect of the steam generator 4 are described in detail in the foregoing, detailed description thereof is omitted. Reference is made to the above description for any technical content relating to the steam generator 4.

In the disinfection system in the dish washer in the prior art, only a water softener, a steam generator and a water cup are assembled and matched with each other, in the using process, the water softener is firstly connected into a tap water pipeline to soften supplied tap water, then the softened water is directly conveyed into the water cup, one part of water in the water cup can be used for supplying a liner of the dish washer, and dish washing work is carried out through the liner. Meanwhile, the other part of moisture in the water cup can be supplied to the steam generator, and after the steam generator acquires the other part of moisture from the water cup, the acquired other part of moisture can be used for generating high-temperature steam to sterilize the inner container.

Therefore, in the existing dish washing machine, the steam generator can only take water from the water cup to generate high-temperature steam, but the water in the water cup can be supplied to the inner container and is communicated with the inner container, and the water cup is generally positioned at the bottom of the inner container, so that the water in the water cup can be polluted and become turbid after the dish washing operation of the dish washing machine is carried out, if the water in the water cup is supplied to the steam generator without filtering, the steam generator is easy to generate a dirty and blockage problem due to impure water, or the water in the water cup is supplied to the steam generator after being filtered, the water is not filtered completely, the steam generator is easy to generate a dirty and blockage condition, and the reason is that the steam generator is easy to be blocked after long use.

In order to solve the above technical problem, the present application provides the following technical solutions.

Referring to fig. 3 to 11, the present embodiment provides a sterilization system of a dishwasher, including a water softener 1; the disinfection system also comprises a water tank 2, wherein the water tank 2 is provided with an inlet 2111, a first outlet 2112 and a second outlet 2121, and the inlet 2111 is connected with the water softener 1; the disinfection system further comprises a water cup 3, the water cup 3 being connected with the first outlet 2112; the sterilization system further comprises a steam generator 4, the steam generator 4 being connected to the second outlet 2121.

Wherein, the water tank 2 is added in the supply system of the dishwasher first, and the water tank 2 has three connection ports of an inlet 2111, a first outlet 2112 and a second outlet 2121 in structure, according to the inlet 2111, the first outlet 2112 and the second outlet 2121, in the assembly connection structure of the water tank 2 with the water softener 1, the water cup 3 and the steam generator 4, the inlet 2111 of the water tank 2 is connected with the water softener 1, the first outlet 2112 of the water tank 2 is connected with the water cup 3, and the second outlet 2121 of the water tank 2 is connected with the steam generator 4.

According to the assembly and connection structure of the water softener 1, the water tank 2, the water cup 3 and the steam generator 4, after running water enters the dish washer, the running water firstly passes through the water softener 1, the water softener 1 can soften the running water, and moisture after softening treatment can firstly enter the water tank 2 instead of directly entering the water cup 3. In this process, the height of the first outlet 2112 in the water tank 2 may be set so that after a certain amount of water is stored in the water tank 2, the water is further transferred to the water cup 3 to supply water to the water cup 3. Therefore, the water tank 2 can be additionally provided with the water softener 1 to supply water to the water cup 3, and the water tank 2 can retain moisture, at the moment, the steam generator 4 is connected with the second outlet 2121 of the water tank 2, so that softened moisture can be directly obtained from the water tank 2, and the water does not need to be obtained from the water cup 3, even if the moisture in the water cup 3 is polluted, the steam generator 4 can also obtain relatively cleaner moisture from the water tank 2 to form high-temperature steam, and the problem of blockage cannot be caused because the moisture used by the steam generator 4 is cleaner.

Meanwhile, the water tank 2 provided in this embodiment may include a tank body 21, where the tank body 21 has a first accommodating cavity 211 and a second accommodating cavity 212, and at least one overflow port 2131 is opened between the first accommodating cavity 211 and the second accommodating cavity 212; the box body 21 is further provided with an inlet 2111 and a first outlet 2112 which are communicated with the first accommodating cavity 211, and a second outlet 2121 which is communicated with the second accommodating cavity 212; the first outlet 2112 is lower than the overflow 2131. The water tank 2 has three connection ports, namely an inlet 2111, a first outlet 2112 and a second outlet 2121, the inlet 2111 of the water tank 2 can be connected with the water softener 1, the first outlet 2112 of the water tank 2 can be connected with the water cup 3, and the second outlet 2121 of the water tank 2 can be connected with the steam generator 4.

The water tank 2 may further include a structure for preventing a reverse flow in the water tank 2 through the first and second receiving chambers 211 and 212 and the overflow port 2131 communicating between the first and second receiving chambers 211 and 212. After the water softener 1 softens the tap water, the tap water enters the first accommodating cavity 211 along the inlet 2111 of the water tank 2, and when the moisture entering the first accommodating cavity 211 reaches the water level of the first outlet 2112 of the water tank 2, the moisture can enter the water cup 3 along the first outlet 2112. Since the first outlet 2112 is lower than the overflow port 2131, the water level in the first receiving chamber 211 does not exceed the first outlet 2112 and thus does not enter the second receiving chamber 212 along the overflow port 2131 until the water cup 3 is filled with water, and only can enter the water cup 3 along the first outlet 2112.

Until the water cup 3 is filled with water, the water level in the first accommodating cavity 211 is gradually increased, and after the water level reaches the overflow port 2131, the water in the first accommodating cavity 211 gradually enters the second accommodating cavity 212 along the overflow port 2131. At this time, the steam generator 4 is connected to the second outlet 2121 of the water tank 2, and can directly receive the softened water from the second receiving chamber 212 of the water tank 2. The second outlet 2121 may be communicated with the bottom of the second receiving cavity 212, so that after a part of water enters the second receiving cavity 212 of the water tank 2, the steam generator 4 may obtain the water from the second receiving cavity 212 of the water tank 2. Meanwhile, a person skilled in the art may set the second outlet 2121 to communicate with the second receiving chamber 212 at a height as required to allow the steam generator 4 to take moisture from the second receiving chamber 212 after the moisture in the second receiving chamber 212 reaches a suitable level.

In this process, only after the water cup 3 is filled with moisture and the moisture in the first accommodating cavity 211 further reaches the water level of the overflow port 2131, the moisture can enter the second accommodating cavity 212 from the first accommodating cavity 211 along the overflow port 2131, so that after the water in the water cup 3 is polluted, if the water is not continuously supplied into the first accommodating cavity 211, the water level in the first accommodating cavity 211 is increased, the moisture in the first accommodating cavity 211 cannot enter the second accommodating cavity 212 along the overflow port 2131, at this time, the polluted water in the water cup 3 cannot flow back to the second accommodating cavity 212, it is ensured that the water in the second accommodating cavity 212 is clean, and the steam generator 4 can obtain the moisture in the second accommodating cavity 212, so that the steam generator 4 cannot be blocked.

The inlet 2111 may be higher than the first outlet 2112, and at this time, the water in the first accommodating chamber 211 may reach the water level height at which the first outlet 2112 is located, so that the water softened by the softener may reach the water level of the first outlet 2112 after entering the first accommodating chamber 211 of the water tank 2 through the inlet 2111, and then enter the water cup 3 through the first outlet 2112. Meanwhile, the volume of the first receiving cavity 211 may be smaller than that of the second receiving cavity 212, because the first receiving cavity 211 is only configured to allow moisture to flow through the water cup 3, and the second receiving cavity 212 is configured to store water, the second receiving cavity 212 needs to store enough moisture to supply the steam generator 4 to generate high-temperature steam, so the volume of the second receiving cavity 212 needs to be larger.

In one embodiment, the water tank 2 further includes a flow restriction plate 213, and the flow restriction plate 213 is disposed in an inner cavity of the tank body 21 to divide the inner cavity into the first receiving cavity 211 and the second receiving cavity 212. In this case, the restrictor plate 213 may be integrally formed with the inner cavity of the case 21, or the restrictor plate 213 may be detachably mounted to the inner cavity of the case 21 so that the restrictor plate 213 can be replaced. The top end of the restrictor plate 213 is provided with a notch, and the notch forms the overflow port 2131, so that the overflow port 2131 can be formed by the inner wall (specifically, the top wall) of the tank body 21 through the restrictor plate 213, and the overflow port 2131 can be arranged at the highest position in the inner cavity of the tank body 21.

As shown in fig. 6 to 9, the water tank 2 further includes a tank cover 22, and the tank cover 22 is installed in cooperation with the tank body 21; a cover opening 221 is formed in the case cover 22, a cylindrical connecting portion 222 protrudes from the cover opening 221, and a first sealing ring 223, a fixing ring 224, a second sealing ring 225 and a screw cover 226 are sequentially sleeved on the connecting portion 222 from the bottom to the top; the retainer ring 224 is in sealing abutment with the first seal 223 and the second seal 225 is in sealing abutment between the connector barrel and the cap 226.

Therefore, after the second sealing ring 225 and the screw cap 226 are screwed and assembled on the connecting portion 222, the cap opening 221 of the cap body is sealed, and in cooperation with the second sealing ring 225 and the screw cap 226, the assembly of the first sealing ring 223 and the fixing ring 224 can further seal the cap opening 221 by screwing and assembling, so that the cap opening 221 has a good sealing effect after the first sealing ring 223, the fixing ring 224, the second sealing ring 225 and the screw cap 226 are assembled and sealed.

In another embodiment, as shown in fig. 12 and 13, the water tank 2 further includes a one-way flow blocking member 214, and the one-way flow blocking member 214 is disposed at the first outlet 2112 to allow fluid to flow out of the first outlet 2112 and prevent fluid from flowing in from the first outlet 2112. The one-way flow blocker 214 can block water flow in one direction and allow water flow in the opposite direction. Through the control of the one-way choke 214 on the water flow, the water flow can only flow from the first accommodating cavity 211 to the water cup 3, but cannot flow from the water cup 3 to the first accommodating cavity 211, so that the dirty water in the water cup 3 is prevented from flowing back to the first accommodating cavity 211, and the moisture acquired by the steam generator 4 is further prevented from being polluted by the sewage in the water cup 3.

The one-way flow blocking element 214 may be a one-way valve, and in addition, the one-way flow blocking element 214 further includes a flow blocking cylinder 2141 and a blocking flap 2142, and is formed by the flow blocking cylinder 2141 and the blocking flap 2142. One side of the blocking piece 2142 is rotatably mounted in the flow blocking tube 2141, for example, one side of the blocking piece 2142 may be rotatably mounted at a port of the flow blocking tube 2141 through a rotating shaft, while the other side of the blocking piece 2142 is in a release state, and the inner cavity of the flow blocking tube 2141 may be opened or closed by rotating along the rotating shaft, so as to form a movable shield for the inner cavity of the flow blocking tube 2141.

Meanwhile, a limiting step 2143 is further disposed in the choke cylinder 2141 to limit the inward rotation of the check piece 2142. Therefore, when the water in the first receiving cavity 211 flows to the cup 3 along the first outlet 2112, the flowing power of the water will flush the stopper 2142, so that the stopper 2142 rotates along the rotation axis, and the inner cavity of the flow blocking barrel 2141 is opened, allowing the water to flow to the cup 3. If the moisture in the water cup 3 is expected to flow to the first receiving cavity 211 along the first outlet 2112, the flowing power of the moisture is applied to the retaining piece 2142, and the retaining piece 2142 is limited and abutted by the limiting step 2143 after rotating in the opposite direction along the rotating shaft, so that the water cannot continuously rotate in the flow blocking barrel 2141, and can only abut against the limiting step 2143 to block the inner cavity of the flow blocking barrel 2141, thereby forming a flow blocking effect.

With continued reference to fig. 1, the sterilization system further comprises a drain pump 5, the drain pump 5 being connected to the water cup 3; the disinfection system also comprises a controller, the controller is in control connection with the draining pump 5, and the draining pump 5 is started to change water for the water cup 3 before the steam generator 4 is started. The controller can control the operation of the drainage pump 5 according to a preset operation program, for example, the steam generator 4 of the dishwasher applies high-temperature steam to the inner container when high-temperature steam sterilization is carried out, the controller can firstly control the drainage pump 5 to start, the drainage pump 5 can form drainage power to drain the water in the water cup 3, meanwhile, the tap water can also have power to supply water to the softener, the water tank 2 and the water cup 3, so that continuous water inlet and drainage actions can be formed in the water cup 3, and water changing operation is carried out on the water in the water cup 3.

Above-mentioned controller control drain pump 5 starts before the high temperature steam disinfection, the reason of carrying out the water change operation to the moisture in drinking cup 3 is, though can remain relatively cleaner moisture in the water tank 2, can supply to steam generator 4 than the more cleaner moisture after polluting in drinking cup 3, slow down steam generator 4's the jam condition, however, drinking cup 3 and water tank 2 are the intercommunication, the moisture in drinking cup 3 is polluted the back, also has the possibility of backward flow to in the water tank 2, and then forms a little pollution to the clean moisture in the water tank 2. Therefore, before the steam generator 4 is sterilized by high-temperature steam, the controller can be used for controlling the drain pump 5 to drain the water in the water cup 3 according to a preset running program, and the water changing operation of continuous water inlet and water outlet is formed on the water cup 3, so that the water in the water cup 3 can be ensured to be cleaner, even the water without any impurity as far as possible, the water in the water tank 2 can be ensured to be very clean, and the steam generator 4 can not have any risk of generating filth and blockage when acquiring the water in the water tank 2.

The disinfection system further comprises a pH value detector for acquiring pH value information in the steam generator 2; the water suction pump 6 of the disinfection system is connected between the water tank 2 and the steam generator 4, and the water suction pump 6 is connected between the water tank 2 and the steam generator 4; the controller is electrically connected with the pH value detector and the water pump 6, and the water pump 6 is controlled to operate according to the pH value information. At this time, the ph detector may determine whether a detergent is added to the water tank 2 by acquiring ph information of the steam generator 2, and the detergent may be used to remove scale formed in the water pipe of the steam generator 4 after the steam generator 4 has been used for a long time.

Because the water line of the steam generator 4 is easily scaled when the dishwasher is used for a long time. In this case, it is necessary to add a detergent with a suitable ph value into the water tank 2, so that the detergent enters the water pipe of the steam generator 4 along with the water flow to remove scale formed in the water pipe of the steam generator 4, for example, citric acid may be used as the detergent. In the specific removing process, the user may actively put the detergent into the water tank 2, or an automatic putting device may be used to put the detergent into the water tank 2 periodically, regularly or quantitatively, which may be set by those skilled in the art according to the requirement.

No matter automatically put in detergent or actively put in detergent, once the detergent is put in the water tank 2, the pH value detector can detect the pH value change of water in the water tank 2, when the pH value information reaches a preset range, a proper amount of detergent can be identified to be put in the water tank 2, and for the identification range of the pH value information, a person skilled in the art can set the pH value according to the factors such as the capacity of the water tank 2 of the dishwasher, the type of the adopted detergent, the interval time of regular cleaning and the like, and the limitation is not made herein.

Therefore, when the pH value detector identifies that the pH value information reaches a preset range, namely after a proper amount of detergent is put into the water tank 2, the operation of the water suction pump 6 can be controlled by utilizing the controller according to a preset operation program, the water suction power of the water suction pump 6 is utilized, the water in the water tank 2 is pumped into the steam generator 4, the water in the water tank 2 is mixed liquid with the detergent, after the water mixed with the detergent is pumped into the steam generator 4 by the water suction pump 6, the water pipeline of the steam generator 4 can be flushed, and the scale formed in the water pipeline of the steam generator 4 is removed by utilizing the detergent, the service life of the steam generator 4 is prolonged, and the effect of high-temperature steam is ensured.

Wherein the sterilization system further comprises a temperature sensor for acquiring temperature information of the steam generator 4; the disinfection system further comprises an annunciator, wherein the annunciator is in data connection with the temperature sensor and generates a prompt signal according to the temperature information. After the temperature sensor acquires the temperature information of the steam generator 4, whether the water pipeline of the steam generator 4 is scaled or not can be judged, and because the generation of scale can cause the temperature of the steam generator 4 to rise, the temperature information of the temperature rise of the steam generator 4 can be acquired through the temperature sensor, for example, the temperature rise speed of the steam generator 4 or the real-time temperature of the steam generator 4 and the like, and whether the water pipeline of the steam generator 4 is scaled or not can be judged. Of course, one skilled in the art may set different temperature ranges for different materials or structures of the water tubes of the steam generator 4 to indicate the scaling problem of the water tubes of the steam generator 4, and the setting is not limited herein.

In addition, the water cup 3 is communicated with the water tank 2, and after the water in the water cup 3 is polluted, the water also has the possibility of flowing back to the water tank 2, so that a little pollution is caused to clean water in the water tank 2. Therefore, before the steam generator 4 is sterilized by high-temperature steam, the water cup 3 can be cleaned firstly, so that the water in the water cup 3 is ensured to be cleaner, even the water without any impurities is ensured to be as far as possible, the water in the water tank 2 is ensured to be very clean, and the steam generator 4 can not generate any risk of dirty blockage when obtaining the water in the water tank 2.

In one embodiment, cleaning the cup 3 comprises: and opening the drainage pump 5 to change water for the water cup 3, and cleaning the water cup 3 by changing water. Specifically, before the steam generator 4 is sterilized by high-temperature steam, the drainage pump 5 can be controlled to be started to drain the moisture in the water cup 3, the drainage pump 5 can form drainage power to drain the moisture in the water cup 3, and meanwhile, the tap water can also have power to supply water to the softener, the water tank 2 and the water cup 3, so that continuous water inlet and drainage actions can be formed in the water cup 3, and water changing operation can be carried out on the moisture in the water cup 3.

In the disinfection method, when the pH value information reaches a preset range, the water pump 6 is started to supply water to the water tank 2, and a water pipeline of the steam generator 4 is cleaned by water flow. This is because the water pipe of the steam generator 4 is likely to form scale after the dishwasher is used for a long time, and at this time, it is necessary to remove the scale formed in the water pipe of the steam generator 4 by putting a detergent with a suitable ph into the water tank 2 so that the detergent enters the water pipe of the steam generator 4 along with the water flow.

When the detergent is put into the water tank 2, the pH value detector can detect the pH value change of the water in the water tank 2, and when the pH value information reaches a preset range, the detergent with a proper amount is put into the water tank 2.
