[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] At present, there are few deodorizing devices for dishwashers, and the effect is not ideal. The deodorizing devices and air purification and sterilization devices inside the dishwasher mostly use ozone and ultraviolet lamps. Ozone devices consume a lot of energy and are not easy to purify completely, which may cause harm to users. The effect of ultraviolet devices is not as expected. Dishwashers will have odors when stored for a long time.

[0029] To facilitate understanding of this embodiment, the first article conveying device disclosed in the embodiment of the utility model is first introduced in detail.

[0030] See also Figure 1 As shown, an embodiment of the utility model provides a dishwasher, comprising: a dishwasher body 1 and a hydroxyl ion purification device; the hydroxyl ion purification device is arranged in the shell of the dishwasher body 1; the hydroxyl ion purification device comprises: a control unit 21 and a hydroxyl ion generator 22; wherein the hydroxyl ion generator 22 is arranged at the top of the shell of the dishwasher body 1; the control unit 21 is used to control the hydroxyl ion generator 22 to start or shut down; the hydroxyl ion generator 22 is used to generate hydroxyl ions after starting to decompose odor molecules and bacteria in the air in the shell.

[0031] In practical applications, a hydroxyl ion purification device for deodorization and sterilization can be arranged in the space inside the outer shell of the dishwasher body 1. The hydroxyl ion purification device includes a control unit 21 and a hydroxyl ion generator 22 controlled by the control unit 21; wherein the hydroxyl ion generator 22 can be arranged at the top of the outer shell, the control unit 21 can be arranged on the inner wall of the outer shell, and the operating end face 212 of the control unit 21 can be arranged on the outer wall of the outer shell; the hydroxyl ion generator 22 is used to transport hydroxyl ions to the air inside the outer shell.

[0032] See also Figure 2 As shown, the hydroxyl ion generator 22 includes a collecting device 221 and an emitting needle 222; the collecting device 221 is used to collect water molecules in the air in the housing; the emitting needle 222 is used to emit a high voltage current to ionize the water molecules to generate hydroxyl ions.

[0033] The hydroxyl ion generator 22 can specifically adopt a nanoe generator, such as a nanoe generator or a nanoeX generator; in the nanoe generator, the moisture in the air can be cooled and condensed, and then high voltage electricity is applied to decompose the water into nano-scale charged water-purifying ions (i.e., hydroxyl ions, also known as nanoe) containing a large number of OH free radicals. In actual implementation, the collection device 221 can collect the moisture in the air and concentrate it inside the generator (specifically, the moisture in the air can be cooled and condensed), and then the emission needle 222 is used to emit a high voltage current to ionize the moisture to produce a large number of hydroxyl ions. Hydroxyl ions can eliminate many bacteria and viruses, inhibit a variety of floating molds and attached bacteria, decompose a variety of harmful substances in PM2.5, inhibit the activity of a variety of allergens and pollen in the air, and also have the effect of purifying and deodorizing. Therefore, the use of the nanoe generator can better deodorize and inhibit bacteria in the space inside the dishwasher shell, thereby achieving the purpose of purifying the odor inside the dishwasher and sterilizing.

[0034] In the specific implementation process, when the air humidity is high, the hydroxyl ion generator 22 has a higher working efficiency and can work more frequently to achieve air purification. When the dishwasher enters the drying stage after washing, the internal air humidity is high, the air flow is large, and the odor molecules are active. At this time, the hydroxyl ion generator 22 is started to ionize the water molecules in the air, generate hydroxyl ions, react with the odor molecules in the air, decompose the odor molecules and bacteria in the air, and achieve the effect of odor removal and disinfection.

[0035] The utility model provides a dishwasher, comprising a dishwasher body and a hydroxyl ion purification device; the hydroxyl ion purification device is arranged in the shell of the dishwasher body; the hydroxyl ion purification device comprises: a control unit and a hydroxyl ion generator; wherein the hydroxyl ion generator is arranged at the top of the shell of the dishwasher body; the control unit is used to control the start or shut down of the hydroxyl ion generator; the hydroxyl ion generator is used to generate hydroxyl ions after starting to decompose odor molecules and bacteria in the air in the shell. The dishwasher can generate hydroxyl ions by starting the hydroxyl ion generator, react with odor molecules and bacteria in the air inside the dishwasher, decompose the odor molecules and bacteria, achieve the effect of odor removal and disinfection, thereby effectively purifying the air inside the dishwasher and improving the user experience.

[0036] For further information, see Figure 3 As shown, the hydroxyl ion purification device further includes a temperature and humidity sensor 23 for detecting the air temperature and air humidity in the housing.

[0037] The temperature and humidity sensor 23 may also be disposed on the inner wall of the housing to detect sensing data, such as the air temperature and air humidity in the housing.

[0038] In this embodiment, the position setting of the temperature and humidity sensor 23 can be changed, and is not limited to the spatial arrangement form in the embodiment.

[0039] In actual implementation, the control unit 21 can control the working state of the hydroxyl ion generator 22 according to the sensing data of the temperature and humidity sensor. Specifically, when the dishwasher runs to the drying stage, the temperature and humidity sensor 23 can detect the temperature and humidity in the cavity (equivalent to the inside of the dishwasher shell) at this time, and record the temperature and humidity at this time as T0 and H0 respectively. At this time, the hydroxyl ion generator 22 works alone to prevent the air moisture from condensing too quickly. Thereafter, the temperature and humidity sensor 23 can collect the humidity (represented by H) and temperature (represented by T) in the dishwasher in real time. When the humidity H is lower than the first preset threshold (represented by H1), or the temperature T is lower than the second preset threshold (represented by T1), or H is lower than the first preset threshold and the temperature T is lower than the second preset threshold, when any of these three situations occurs, the control unit 21 can control the increase of the operating voltage of the hydroxyl ion generator 22 during the next start-up cycle of the hydroxyl ion generator 22, so that the hydroxyl ion generator 22 can ionize water molecules more efficiently, thereby achieving a higher purification efficiency.

[0040] For further information, see Figure 4 As shown, the hydroxyl ion purification device further includes a heating module 24 and an air driving device; the heating module 24 is used to heat the air in the housing; and the air driving device is used to form air circulation in the housing.

[0041] The heating module 24 and the air driving device can be arranged on the inner wall of the housing and controlled by the control unit 21 .

[0042] The heating module 24 may be a heating wire heater, a heat pump heater, or may be miniaturized according to the volume of the shell to occupy a smaller volume.

[0043] The air driving device may be a fan 25, a circulating fan, a micro air pump, etc.

[0044] Preferably, the air driving device adopts a fan 25. When the fan 25 is adopted as the air driving device, the number of the fans 25 is preferably two, and the installation positions of the two fans 25 in the housing correspond to each other.

[0045] Specifically, the two fans 25 may be respectively arranged at the upper left and lower right of the outer shell (equivalent to the cavity, also called the inner tank of the dishwasher).

[0046] In this embodiment, the positions of the heating module 24 and the fan 25 can be changed, and are not limited to the spatial arrangement in the embodiment. For example, the two fans 25 can also be respectively arranged at the upper right and lower left of the housing, or at the front and rear of the housing, etc. In short, the installation positions of the two fans 25 in the housing correspond to each other.

[0047] In addition, in order to ensure that air circulation can be formed in the casing, the directions of the two fans 25 must be opposite. For example, one of the fans 25 is an exhaust fan and the other fan 25 is a supply fan. The supply fan and the exhaust fan are the same fans, but the installation directions are different. Among them, the direction of the exhaust fan is left-handed (also called clockwise), and the motor blows air toward the fan blades; the direction of the supply fan is right-handed (also called counterclockwise), and the motor blows air toward the other side of the fan blades.

[0048] In actual implementation, assuming that the supply fan is installed in the lower right corner of the cavity and the exhaust fan is installed in the upper left corner, the air can be driven to blow out from the supply port and then drawn out from the exhaust port, thereby realizing air circulation in the shell.

[0049] In the specific implementation process, the control unit 21 can also control the working state of the heating module 24 and the fan 25 according to the sensing data of the temperature and humidity sensor 23. Specifically, when the temperature and humidity sensor 23 detects that the temperature in the cavity is T<T1 or the humidity in the cavity is H

[0050] Furthermore, during the operation of the fan 25 and the heating module 24, the temperature and humidity sensor 23 can still detect the temperature T and humidity H in the cavity in real time. Before detecting that T>T0 or H>H0, the fan 25 and the heating module 24 need to be started until T>T0 or H>H0 is detected. The control unit 21 can then control the fan 25 and the heating module 24 to be turned off at this time, and only the hydroxyl ion generator is operated.

[0051] For details, please refer to Figure 5 ​A control flow chart of a control unit is shown, and the control unit 21 can intelligently adjust the working states of the hydroxyl ion generator 22, the fan 25 and the heating module 24 according to environmental changes. First, the control unit 21 can obtain the cavity temperature T0 and humidity H0 detected by the temperature and humidity sensor 23 when the dishwasher runs to the drying stage, and then control the hydroxyl ion generator 22 to work alone. At this time, the fan 25 and the heating module 24 do not work. The hydroxyl ion generator 22 working alone can prevent the air moisture from condensing too quickly. Thereafter, the control unit 21 obtains the humidity H and temperature T in the dishwasher collected in real time by the temperature and humidity sensor 23. When the control unit 21 obtains the cavity temperature T<T1 or the cavity humidity HT0 or H>H0 collected in real time by the temperature and humidity sensor 23, then the fan 25 and the heating module 24 are turned off, and only the hydroxyl ion generator 22 is operated.<h1>

[0052] For further information, see Figure 6 As shown, the dishwasher further includes a power module 2; the power module 2 is arranged in the housing and is used to supply power to the hydroxyl ion purification device.

[0053] In actual implementation, a power module 2 for powering the hydroxyl ion purification device is also provided in the outer shell of the dishwasher body 1. Specifically, it can power electrical components such as the heating module 24, the fan 25, the hydroxyl ion generator 22, the control unit 21, and the temperature and humidity sensor 23. The power supply can be a rechargeable power supply fixed in the outer shell, or it can be a plug-in rechargeable mobile power supply.
