Detailed description of the invention
Embodiment one:
The present embodiment provides a kind of washing machine, including casing, casing top is provided with control seat, control seat is provided with control system, steel ladle it is provided with in casing, connecting drain assembly bottom steel ladle, be provided with the data obtaining module for obtaining temperature, rh value in described casing, data obtaining module electrically connects with controlling system.In the present embodiment, data obtaining module is temperature sensor and relative humidity sensor, generally arranging the outside of steel ladle, relatively costly even can be arranged in steel ladle, it would however also be possible to employ the relatively costly sensor that can simultaneously detect temperature and relative humidity.
Additionally, data obtaining module can also adopt Wi-Fi module, Wi-Fi module to be arranged in casing the outside being positioned at steel ladle, and Wi-Fi module is used for from the Internet download local temperature, rh value.
Embodiment two:
How the washing machine just specifically describing the present invention below realizes detection bacterial reproduction amount.Illustrate for data obtaining module for temperature sensor and relative humidity sensor.
nullA kind of method of use in washing machine detection bacterial reproduction amount,Washing machine described in embodiment one performs,Data obtaining module is temperature sensor and relative humidity sensor,Washing machine is upper after once washing procedure terminates,The control system t at set intervals of washing machine just obtains once real-time temperature by temperature sensor and relative humidity sensor、Rh value,And save,After T time,Control system obtains n times temperature altogether、Rh value,Control system is by n times temperature、The temperature of the appropriate bacterial breeding prestored in rh value and control system、Rh value compares,If n times temperature、Rh value has at least the number of times of K% to simultaneously fall in the temperature prestored、Within the scope of rh value,And T is more than the setting value T1 in control system,Then start sterilization procedure or remind user need degerming and be confirmed whether to start sterilization procedure by user.
The temperature of the appropriate bacterial breeding prestored in control system, rh value scope is with the fungus growth condition that harm is maximum for standard, temperature range is 25~30 DEG C, RH range is 65%~90%, and T1 is the time entering exponential phase in the fungus growth cycle, T1=6~8 hour.
Time t is 0.5~1 hour, control system obtain temperature, rh value interval t time secondary equal, namely control system and obtain temperature, a rh value every the identical time, or have at least twice interval t not etc., namely the time having at least two minor ticks different obtains temperature, a rh value, increases the feasibility of stochastic sampling.
K% value is set by the user according to user's request or is provided multiple fixed value to be selected by user by manufacturer, such as some user is higher to degerming demand, can K% value be set a little bit smaller, it is high that degerming demand is not as, can K% value be set greatly a bit, 0≤K%≤100%, when user sets or selects K% as 0, bacterial reproduction amount need not be detected, to start sterilization procedure every time, when K% is 100%, only all temperature, rh value all simultaneously falls in the temperature prestored, just start sterilization procedure within the scope of rh value or remind user need degerming and be confirmed whether to start sterilization procedure by user.
nullSuch as,T=1 hour,K%=50%,N=8,Then the control system of washing machine was just detected once real-time temperature by temperature sensor and relative humidity sensor every 1 hour、Rh value,And save,The control system of washing machine have recorded 8 temperature altogether、After rh value,Assume there are 6 temperature、Rh value drops on the temperature of the suitable mycete breeding prestored、Within the scope of rh value,Namely there is the temperature of 75% number、Rh value drops on the temperature of the suitable mycete breeding prestored、Within the scope of rh value,More than 50%,And the time of 8 hours have also exceeded the time entering exponential phase in the fungus growth cycle,Therefore the environment appropriate bacterial growth that system judges in steel ladle is controlled,Through the breeding of 8 hours,Reach to need degerming standard,Therefore,Start sterilization procedure,Or remind user to need degerming.
When same, if the control system of washing machine have recorded 8 temperature, rh values altogether, only 3 temperature, rh value drop on prestore the temperature of suitable mycete breeding, within the scope of rh value, namely only have the temperature of 37.5% number, rh value drop on prestore the temperature of suitable mycete breeding, within the scope of rh value, less than 50%, then control system and judge to start sterilization procedure.
When temperature sensor and relative humidity sensor detection, it is necessary to power supply, owing to the time of temperature sensor and relative humidity sensor detection real time temperature, rh value is longer, generally require that washing machine is in holding state.Washing machine is in holding state, and after referring to that washing machine completes washing procedure, washing machine still connects external power source or to arrange accumulator in washing machine be that control system, temperature sensor and relative humidity sensor are powered.And have 24 hours standby types and can not standby type in the market, 24 hours therein standby types, control system not power-off due to washing machine, within round-the-clock 24 hours, remain able to carry out the read-write of data, transmission, it is easy to receive temperature that temperature sensor and relative humidity sensor detect, relative humidity information and saves, so in this type, it is all feasible that the detection work of bacterial reproduction amount, sterilization procedure are set between before starting after last washing procedure terminates random time section to washing procedure next time.
For can not for standby type, dialog box can also be shown on guidance panel, ask the user whether to carry out the detection work of bacterial reproduction amount, if user selects needs, then washing machine continued power after completing washing procedure, control system, temperature sensor and relative humidity sensor continuous firing, otherwise washing machine automatic shutdown power-off after completing washing procedure.Thus do not require that washing machine is 24 hours standby types, it is possible to when control system be judged to need not degerming or automatic shutdown power-off after sterilization procedure terminates.And in this case, can while user chooses whether to need to carry out the detection work of bacterial reproduction amount, if just allowing user select control system judges whether start sterilization procedure when needing degerming, avoid needing again user again to carry out selecting operation after the detection work of bacterial reproduction amount, it is not necessary to user waits or again returns to washing machine place.Certainly, generally, user selects to carry out the detection work of bacterial reproduction amount, it is simply that want to carry out degerming.Before starting shooting at washing machine, control system cannot work, so the detection work of bacterial reproduction amount, sterilization procedure are generally set in after washing procedure terminates.
Embodiment three:
The present embodiment and embodiment two are distinctive in that, data obtaining module is Wi-Fi module, and for whether washing machine is standby type, Wi-Fi module has different occupation modes.
For 24 hours standby types, Wi-Fi module has two kinds of occupation modes: the first is that the control system of washing machine is by the disposable historical record downloading local temperature, rh value from the Internet of Wi-Fi module, each temperature, rh value historical record between interval time t, be usually and download when user selects to carry out the detection work of bacterial reproduction amount;The control system that the second is washing machine just downloads once local real-time temperature, rh value by Wi-Fi module per interval t from the Internet.In this type, detection work, the sterilization procedure of bacterial reproduction amount are set in after washing procedure terminates or washing procedure start before be all feasible.
For can not for standby type, Wi-Fi module has two kinds of occupation modes equally: the first is that the control system of washing machine is by the disposable historical record downloading local temperature, rh value from the Internet of Wi-Fi module, each temperature, rh value historical record between interval time t, be usually and download when user selects to carry out the detection work of bacterial reproduction amount;The second is when user selects the detection work carrying out bacterial reproduction amount, and washing machine continued power, the control system of washing machine just downloads once local real-time temperature, rh value by Wi-Fi module per interval t from the Internet.In this type, the detection work of bacterial reproduction amount, sterilization procedure are generally set in after washing procedure terminates.
It is referred to embodiment two as other parameter aspect.Therefore repeat no more.In embodiment two and embodiment three, it is all using the growth cycle of mycete as reference standard, because the investigation of specialty health organ finds, washing machine antibacterial exceeding standard rate is up to 81.3%, wherein mycete recall rate 60.2%, total coli group recall rate is up to 100%, and mycete is maximum to harm.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can be variously modified according to the present invention and deform, and without departing from the spirit of the present invention, all should belong to scope defined in claims of the present invention.
