In this embodiment, food processor can be cooking machine, for example broken wall cooking machine, and at this moment, reducing mechanism can be the blade. The food processor may be a juice extractor, in which case the comminution means may be a screw. The food processor may be a pasta machine, in which case the comminuting device may be a blender.

The food processor provided by this embodiment may, but is not limited to, include a food processor, a juice extractor, and a pasta machine, and this embodiment is not limited and described herein. The following embodiments of the present invention are mainly described by taking the food processing machine as a food processor as an example, and the cleaning principle of the remaining food processing machines including the wheaten food machine and the juice extractor is the same as the cleaning principle of the wheaten food machine, and the description of the embodiments is omitted.

The main control chip may be a single chip microcomputer (MCU for short), and is used to execute a cleaning and maintenance method of the food processor.

Based on the food processor provided in the foregoing embodiments, this embodiment provides a cleaning and maintenance method for a food processor, fig. 1 is a flowchart of a cleaning and maintenance method for a food processor according to an exemplary embodiment of the present invention, an execution main body of an embodiment of the present invention may be a main control chip, as shown in fig. 1, and the cleaning and maintenance method for a food processor according to this embodiment may include:

s101: before the food processor prepares the slurry, the main control chip detects the use condition of the food processor, and the use condition is used for expressing at least one of the use frequency and the use frequency of the food processor.

In practical application, some food processors do not have a self-cleaning function, and the food processors with the self-cleaning function only clean the crushing cavity formed by matching the cup body and the cup cover after pulping is finished, however, when the food processors are frequently used or not used for a long time, the crushing cavity formed by matching the cup body and the cup cover is easy to breed bacteria and dust, so that bacteria and dust exist in pulping solution, and the pulping quality is reduced.

In this embodiment, before the food processor prepares the slurry, the main control chip detects the usage of the food processor to determine the frequency and the number of times of use of the food processor, and determines whether the food processor needs to be cleaned and maintained according to the frequency and the number of times of use of the food processor.

S102: and when the service condition of the food processor meets the preset condition, sending out cleaning and maintenance prompt information, wherein the cleaning and maintenance prompt information is used for requesting the cleaning and maintenance of the crushing cavity.

In the present embodiment, the cleaning maintenance can be applied to a food processor having no self-cleaning function, and can also be applied to a food processor having a self-cleaning function. For the food processor without the self-cleaning function, when the service condition of the food processor meets the preset condition, a cleaning and maintenance prompt message is sent to a user, and the cleaning agent and the cleaning fluid (such as cleaning water) are added into the crushing cavity by the user and are fused to form washing water, so that the cleaning and maintenance of the food processor are realized.

For the food processor with the self-cleaning function, when the service condition of the food processor meets the preset condition, cleaning and maintenance prompt information is sent to a user, and the cleaning and maintenance prompt information is used for instructing the user to add cleaning agent while requesting cleaning and maintenance of the crushing cavity. After receiving an instruction of determining cleaning and maintenance by a user and adding a cleaning agent into the crushing cavity by the user, the main control chip controls the water pump to automatically clean fluid (such as cleaning water) into the crushing cavity, so that the cleaning and maintenance of the food processor are realized. The cleaning agent is matched during cleaning and maintenance, so that hard stains can be removed, and the maintenance and cleaning effects are improved.

In one example, when cleaning and maintaining the crushing cavity, the method can further comprise the following steps: the main control chip controls the crushing device to stir so as to enable washing water for cleaning and maintenance to soak the crushing cavity and enable cleaning agents contained in the washing water to be effectively dissolved.

In this embodiment, after the cleaner was put into to the cup and wasing water, main control chip control reducing mechanism stirred, firstly the stirring can make the cleaner effectively and dissolve fast, guarantees the cleaning performance. Secondly, the washing water formed by the fusion of the cleaning agent and the cleaning water can generate foam by stirring and infiltrate all parts of the cup body and the cup cover, thereby ensuring that the adhered substances on the cup wall are softened, removing the strong-adhesion stains and improving the maintenance and cleaning effects. Wherein, reducing mechanism accessible motor control realizes rotating the stirring.

In one example, the main control chip controls the crushing device to stir, and may include: the main control chip controls the crushing device to perform variable speed stirring at a second preset rotating speed and then at a third preset rotating speed, and the variable speed stirring is used for enabling the washing water to soak the whole crushing cavity. In this embodiment, the washing water may be mixed at a variable speed to wet the entire pulverization chamber. Optionally, the second preset rotating speed is smaller than the third preset rotating speed, and the washing water can be effectively ensured to be full at any position of the cup body by adopting high-low variable speed stirring, so that no cleaning dead angle is formed, and the cleaning effect is ensured.

The cleaning and maintaining method of the food processor provided by the embodiment of the invention can prompt a user whether to clean and maintain according to the use frequency or use times of the food processor before pulping, can effectively clean the inside of the cup body, kill bacteria, remove strongly adhesive stains and improve the maintenance and cleaning effects.

In an exemplary embodiment of the present invention, when the usage condition of the food processor satisfies a preset condition, the cleaning and maintenance of the grinding cavity may include the following two implementation manners:

the first implementation mode comprises the following steps: when the using times of the food processor exceed the preset value, the crushing cavity is cleaned and maintained so as to sterilize the crushing cavity. Because the cup body of the food processor is easy to breed bacteria when being processed for a plurality of times continuously, in the embodiment, the main control core can record the use times of the food processor, and the food processor is cleaned and maintained after being used for a plurality of times continuously, so that the effects of cleaning the cup body, sterilizing and storing the food processor are achieved. The preset value is a preset fixed value and can be set by a user or set by an operator when the operator leaves a factory.

The second implementation mode comprises the following steps: when the food processor is not used within the preset time, the crushing cavity is cleaned and maintained so as to sterilize and decontaminate the crushing cavity. Because the cup body of the food processor is easy to breed bacteria and dust when the cup body of the food processor is not used for a long time, in the embodiment, the main control core can record the use frequency of the food processor, namely the time interval between every two uses, and after the food processor is not used for a long time, the cup body is cleaned and maintained, so that the effects of sterilizing, preserving and decontaminating are achieved. The preset time is a preset fixed value and can be set by a user or set by an operator when the operator leaves a factory.

In an example embodiment of the present invention, performing cleaning maintenance on the pulverizing chamber may include: and (5) a sterilization stage.

In an example, the cleaning service may comprise a sterilization phase to sterilize the comminution chamber when the number of uses of the food processor exceeds a preset value, i.e. when the food processor is used several times in succession.

The sterilization phase may include: when the washing water is filled into the crushing cavity, the main control chip controls the heating device to heat the temperature in the cup body to a first temperature, and the first temperature is used for enabling the washing water to generate foam with a preset amount when the crushing device stirs so as to sterilize.

In this embodiment, after the washing water is filled into the crushing cavity, a heating process of a continuous stirring belt, that is, a hot water and stirring manner, may be adopted to perform sterilization, where the hot water is the washing water with the water temperature of the first temperature. The first temperature is the best temperature that the cleaner can effectively dissolve, can make the washing water produce a large amount of foams when reducing mechanism stirring through the mode of hot water + stirring, improves maintenance and clean effect. When the foam is generated by hot water and stirring, the rotation speed of the crushing device does not exceed 2000RPM, for example, the stirring can be carried out at 1000RPM to 2000 RPM.

In one example, the first temperature may be greater than or equal to 80 ℃ and temperatures above 80 ℃ are temperatures at which the cleaning agent is effectively dissolved.

In an example, the value range of first temperature is 80 ~ 87 ℃, because when the temperature is higher than 87 ℃, the detergent foaming can appear spilling over unusually, and the setting of this embodiment first temperature can ensure that the detergent effectively dissolves between 80 ~ 87 ℃, and the washing water produces a large amount of foams and can not spill over the cup during the stirring.

In an example, the value of the first temperature can be 85 ℃, and a 3 ℃ allowance is reserved, so that the phenomenon that the foam overflow is abnormal due to the fact that the temperature detection is delayed and the actual temperature is too high is prevented.

In an exemplary embodiment of the invention, cleaning and servicing the pulverization chamber comprises: a sterilization stage and a decontamination stage.

In one example, the cleaning and maintenance may comprise a sterilization phase and a decontamination phase for sterilizing and decontaminating the comminution chamber when the food processor is not in use for a preset time, i.e. when the food processor is not in use for a long time.

In this embodiment, the sterilization stage may be followed by a decontamination stage to achieve sterilization and decontamination of the pulverization chamber. The sterilization phase is the same as that of the above embodiments, and the description of this embodiment is omitted.

The decontamination phase may include: the main control chip controls the heating device to heat, the first temperature is maintained for a preset time, and the preset time is used for softening stains in the crushing cavity.

Wherein the predetermined time may be greater than or equal to 4 minutes.

In this embodiment, after the cup body is heated to the first temperature, the first temperature of the cup body is controlled to be maintained for more than 4 minutes, so that the dirt is softened and sterilized.

In an exemplary embodiment of the present invention, the main control chip controls the heating device to heat, and when the temperature of the cup body is increased to a first temperature, the main control chip may control the heating device to heat at a first preset interval, where the first preset interval is used to avoid overflow of washing foam caused by temperature overshoot of the continuous heating crushing chamber.

The value range of the first preset interval can be 3-10S, and optionally, the first preset interval can be 5S.

In practical application, after the heating device stops heating, the temperature in the cup body rises. In this embodiment, when adopting hot water + stirring mode sterilization, through heating device intermittent heating to first temperature, can avoid heating the temperature after stopping temperature uprush too high for the foam that uprush process stirring washing water produced overflows the cup.

In an exemplary embodiment of the present invention, the main control chip controls the crushing device to stir at a second preset interval, and the second preset interval is used for avoiding overflow of washing foam due to continuous stirring.

The value range of the second preset interval can be 20-40S.

In practical use, the temperature of the washing water may be continuously increased during heating of the continuous stirring belt. In this embodiment, when adopting hot water + stirring mode sterilization, can be through reducing mechanism intermittent type stirring, give the broken bubble process of foam when reaching the radiating, the foam that the continuous stirring area heating of prevention leads to spills over.

In an exemplary embodiment of the present invention, the sterilization phase of the above embodiment may be executed in a cycle, or the sterilization phase and the decontamination phase of the above embodiment may be executed in a cycle, so as to ensure that the continuous temperature is maintained at the first temperature (for example, above 80 ℃) for 15min, and ensure that the hot water flushing time is above 15min, thereby ensuring the sterilization effect. According to pasteurization, the temperature is maintained at 80 ℃ for more than 20min, various growth pathogenic bacteria can be killed, and the sterilization efficiency can reach 97.3% -99.9%. In order to guarantee the timeliness, the scheme is circulated for 3 times in total, so that the temperature of the cup body is maintained for more than 20 minutes at more than 80 ℃. In addition, the compound is matched with an acidic or alkaline cleaning agent to effectively kill bacteria. Meanwhile, the acidic or alkaline cleaning agent effectively soaks attachments on the cup wall and the cup cover in an environment with the temperature of more than 20min and 80 ℃, softens hard stains, and effectively cleans the cup body, a crushing device (such as a crushing blade), the cup cover and the like.

In an exemplary embodiment of the present invention, the cleaning and maintaining the pulverization chamber may further include:

a drainage stage: and discharging the washing water, controlling the crushing device to rotate at a first preset rotating speed while discharging the washing water, and rotating to generate airflow to blow the foam at the bottom of the crushing cavity so as to discharge the foam at the bottom of the crushing cavity.

In the present embodiment, after the sterilization stage and the decontamination stage of the above-described embodiments are performed, a drain stage, that is, a drain valve is opened to drain the washing water and the bubbles in the cup body, is performed.

Because a large amount of foam exists in the cup body, particularly at the bottom of the cup body, during actual water drainage, the foam at the bottom of the cup body cannot be removed. In the embodiment, when the drainage valve is opened, the crushing device is controlled to stir and rotate, and the air flow generated by rotation of the crushing device is utilized to discharge the foam in the cup body, particularly the bottom of the cup body, so that the foam is prevented from remaining at the bottom of the cup body, and the foam in the cup body of the food processor can be effectively removed.

In this embodiment, when the washing water is drained, the crushing device is controlled to rotate at the first preset rotating speed, table 1 is a relation table between the rotating speed of the crushing device and the drainage time, as shown in table 1, the value range of the first preset rotating speed may be 3000RPM to 5000RPM, the drainage time may be shortened, that is, the drainage speed may be accelerated by adopting a stirring and drainage mode. Optionally, the value range of the first preset rotating speed can be 3000RPM, so that the noise is reduced while the quick water drainage is ensured.

TABLE 1

Rotational speed	300mL drainage time
		0	13S
1000RPM	12S
		2000RPM	12S
3000RPM	8S
		4000RPM	6S
5000RPM	6S

In one example, when the crushing device is controlled to rotate at the first preset rotation speed, the method may further include:

injecting a first preset amount of cleaning fluid into the crushing cavity at preset intervals, wherein the cleaning fluid comprises cleaning water so as to attach foams in the crushing cavity to the surface of the cleaning water; injecting cleaning water while the crushing device rotates for the air flow generated by the rotation of the crushing device to drive the cleaning water and the foam attached to the surface of the cleaning water to rotate together so as to discharge the foam in the crushing cavity.

In practical application, after the washing water is drained, a large amount of foam still exists on the cup body, particularly on the bottom of the cup body, for example, due to the heat function of soybean milk or rice paste, a large amount of foam can not be directly drained after the washing water is drained, and the cup cannot be effectively cleaned.

In this embodiment, after the washing water is drained, the washing fluid is injected into the cup body, and the crushing device is controlled to rotate at the same time, so that the crushing knife rotates to generate air flow to blow the washing fluid and the foam to reduce the foam.

Specifically, in the foam reducing stage of pumping water (injecting cleaning water), stirring and draining, the cleaning water and the foam are mutually interacted by injecting the cleaning water into the cup body, namely the foam in the cup body is attached to the surface of the cleaning water under the conditions of gravity, density and other factors. Under the action of the air flow generated by the rotation of the crushing device, the cleaning water and the foam attached to the surface of the cleaning water rotate together, and the cleaning water and the foam can be discharged out of the cup body together in the state that the discharge port of the cup body is opened.

In addition, when water pumping (water injection), stirring and water draining are adopted, the washing water can directly impact on the crushing device (such as the crushing blade) under the stirring rotation of the crushing device, and the effect of cleaning the crushing device can be achieved.

In one example, the first preset amount may be greater than or equal to 40ml, i.e., the weight of injected washing water (which may be referred to as the water amount) is greater than or equal to 40 ml. Table 2 shows the relationship between the amount of water injected and the foam rinsing effect (i.e., the amount of foam remaining in the cup body), and as shown in table 2, the foam in the cup can be reduced when the amount of water injected is 40ml or more. Optionally, the first preset amount can be 50ml, so that the flushing purpose can be achieved, and water can be effectively saved.

In an exemplary embodiment of the present invention, after the draining stage, the method may further include:

and injecting a second preset amount of cleaning fluid into the crushing cavity, wherein the second preset amount of cleaning fluid is used for carrying out secondary washing on the foam in the crushing cavity.

Because the foam can not be ensured to be completely removed after the drainage stage, in the embodiment, after the drainage stage, namely the drainage valve is closed, a second preset amount of cleaning water is injected into the crushing cavity so as to carry out secondary washing on the foam in the crushing cavity, ensure that the washing water of the cup cover and the cup body is cleaned, and ensure the cleaning effect.

In one example, the crushing device is controlled to stir while water cleaning water is added, the stirring can enable the added cleaning water to wet the cup wall, and the phenomenon that after the water is drained and the cup wall is dried, partial foam adhered to the cup wall is dried and condensed on the cup wall, and scaling is easy to occur is avoided.

In one example, when the washing water is heated for the second washing, the washing water may be added for a plurality of times, for example, the washing water is washed with hot water at a preset temperature (above 80 ℃) and then with normal temperature water, so as to ensure that the foam in the cup body is completely discharged and ensure the washing effect. Wherein, continuous hot water cleaning is used to ensure that the washing water of the cup cover and the cup body is completely cleaned. After the hot water is used, cold water is used for cleaning once, so that the cleaning effect is ensured.

In the embodiment of the present invention, when the washing water is used for the second rinsing, the washing manner is the same as the washing manner of the washing water used in the above embodiment, for example, the washing water is stirred while being heated, the washing water is intermittently stirred, or the washing water is stirred at a variable speed, and details of this embodiment are not repeated.
