Description

一种洗碗机及其交流洗涤电泵调速控制方法和系统 A dishwasher washing pump and AC speed control system and method

技术领域 FIELD

[0001] 本发明属于洗碗机控制技术领域,尤其涉及一种洗碗机及其交流洗涤电泵调速控制方法和系统。 [0001] The present invention belongs to the technical field control the dishwasher, and in particular to a dishwasher washing pump AC speed control system and method.

背景技术 Background technique

[0002]目前,洗碗机作为一种餐具洗涤设备被广泛用于餐厅、饭店、家庭等需要使用各类餐具的场所,以对餐具进行批量洗涤,提高了餐具洗涤效率,并且还可清除餐具上的细菌,有益于人们的身体健康。 [0002] Currently, as a dishwasher dishwashing equipment is widely used in restaurants, hotels, home and other places need to use all kinds of dishes to wash batch of tableware, cutlery improved washing efficiency, and can also clearing dishes bacteria, good for people's health.

[0003] 现有的洗碗机通常是采用交流单速电泵技术,洗涤电泵的转速被设计成单高速运行,为了提高洗涤电泵的效率,在50Hz交流供电时,洗涤电泵的转速被设计在2800r/m (转/分钟)以上,而在60Hz交流供电时,洗涤电泵的转速被设计在3200r/m以上。 [0003] The dishwasher is typically a conventional single speed AC pump technology, the pump rotational speed is washed designed as a single high-speed operation, to improve the efficiency of the washing pump, at 50Hz AC power supply, the washing pump speed It is designed in 2800r / m (revolutions / min) or more, and in the 60Hz AC power supply, the washing pump rotational speed is designed in 3200r / m or greater. 洗涤电泵在单纯按照高速进行运转时,其水流压力大且水流量大,容易产生振动且噪音大。 In accordance with a simple washing pump is operated at high speed, which large water flow and water pressure, and a large noise is prone to vibration. 如果是在控制洗涤水量的情况下,由于洗涤电泵处于高速运转,所以在水量较少时会因水回流不及时而处于空载或半空载状态,从而导致洗涤电泵的运行状态不稳定且振动噪音更大,并有可能产生刺耳的异常声响;同时,在洗碗机执行洗涤操作的过程中,洗涤电泵中的电机的功率一直处于大功率状态,进而导致能耗增加,能效较低。 If in the case of the control of the amount of washing water, since the washing pump at high speed, so that when water due to low water reflux untimely or the air in the unloaded state of the carrier, resulting in an unstable operating state of the washing pump noisier and vibration, and may produce abnormal noise harsh; while performing a washing operation in the dishwasher, a washing pump in the power of the motor has been in a power state, leading to increased power consumption, more energy efficiency low.

[0004] 针对上述洗涤电泵在单高速运转时所存在的噪音大问题,现有技术通过在洗碗机的内胆和底部加贴大量沥青阻尼,并在洗碗机的外面包裹隔音和吸音棉材料,以达到降噪的目的。 [0004] For the wash pump noise is a big problem when the presence of a single high-speed operation, the large number of prior art pitch damping by affixing the liner and the bottom of the dishwasher, and wrapped in insulation and sound absorbing outside of the dishwasher cotton material, to achieve the purpose of noise reduction. 但这种方式不仅增加了洗碗机整机成本,而且由于沥青阻尼会大量吸热,所以会造成整机能耗增加,同时也会降低具备自然干燥功能的洗碗机对餐具的干燥效果。 However, this approach not only increases the overall cost of a dishwasher, and because a large number of heat-absorbing asphalt damping will be, it will cause an increase in overall energy consumption, but also reduce the drying effect with natural drying function dishwasher for cutlery.

[0005] 为了同时解决洗涤电泵在单高速运转时所存在的噪音大和能耗高的问题,现有技术在洗涤电泵中采用无刷直流电机,并通过直流变频调速系统控制该无刷直流电机,洗涤电泵中的无刷直流电机可以根据预先设定的程序进行调速设计,可在合理的转速范围内使洗碗机在运行过程中保持小噪音和低能耗,但由于直流变频调速系统较为复杂且成本高,所以其无法在低成本的前提下使洗涤电泵的噪音减小和能耗降低。 [0005] In order to simultaneously solve large noise and high energy consumption in the single washing pump in the presence of high-speed operation, the prior art brushless DC motor in the washing pump, and controlling the variable speed system by a DC brushless DC motor, the washing pump brushless DC motor speed can be designed according to a preset program, so that the dishwasher can be within a reasonable range of speeds and low power consumption remains low noise during operation, but the DC inverter speed control system more complex and costly, so it can not enable the washing pump noise reduction and reduced power consumption under the premise of low cost.
