[0066] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0067] According to an embodiment of the present invention, a control method for drinking water equipment is provided. The method is also used for drinking water equipment. The drinking water equipment can be a drinking machine, a pipeline machine or other drinking water equipment. The drinking water equipment is provided with a temperature measuring device. The temperature measuring device is used to detect the temperature in the area between the water outlet and the receiving base of the water receiving container. Specifically, the control method for the drinking water equipment can be executed by a control device in the drinking water equipment. Figure 1 : is a flow chart of a control method of a drinking water device according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:
[0068] Step S101, after the drinking water device discharges water, determine the temperature distribution in the area between the water outlet and the receiving base.
[0069] The drinking water device is provided with a display control panel. When the user needs to receive water, the drinking water device can be started by operating on the display control panel. After receiving the start signal, the drinking water device starts to discharge water in response to the start signal. Specifically, the corresponding water flow can be released according to the user's needs, such as cold water, warm water, hot water, etc. After starting and discharging water, the temperature in the area between the water outlet and the receiving base of the water receiving container is detected by the temperature measuring device. Specifically, after the water is discharged, the control device can control the temperature measuring device to scan or multi-point temperature measurement in the area between the water outlet and the receiving base of the water receiving container, so as to determine the temperature distribution in the area. After the water is discharged, there may be uneven temperature in the area, such as the highest temperature near the water outlet.
[0070] In some optional embodiments, the temperature measuring device may be disposed on the side wall between the water outlet and the receiving base, and the temperature measuring device may adopt a non-contact temperature measuring sensor, such as an infrared thermopile sensor.
[0071] In some optional implementations, the temperature distribution in the area between the water outlet and the receiving base may be detected after the water outlet of the drinking water device reaches a certain preset time.
[0072] Step S102, determining the position of the bottle mouth of the water receiving container based on the temperature distribution.
[0073] For the temperature distribution of the area between the water outlet and the receiving base, specifically, the area with obvious temperature changes can be determined by analyzing the temperature distribution. The area with obvious temperature changes can indicate the heat exchange boundary between the liquid inside the water receiving container and the external environment to a certain extent. Based on the analysis of the temperature difference, the position of the bottle mouth of the water receiving container can be inferred. After determining the position of the bottle mouth of the water receiving container, the water outlet of the drinking water device can be controlled to stop discharging water after reaching the bottle mouth position. Optionally, after determining the position of the bottle mouth, the angle and position of the water outlet can also be adjusted to ensure that the water flows accurately into the water receiving container to avoid splashing or waste.
[0074] The control method of the drinking water device provided in the embodiment of the present invention is to set a temperature measuring device on the drinking water device. After the drinking water device discharges water, the temperature distribution in the area between the water outlet and the receiving base of the water receiving container is obtained through the temperature measuring device, and then the bottle mouth position of the water receiving container is determined based on the temperature distribution. This method determines the bottle mouth position through the temperature distribution, and then can control the drinking water device to stop discharging water according to the bottle mouth position, thereby reducing the user's operating difficulty. In addition, this method does not need to consider the shape and size of the water receiving container, has higher adaptability, and improves the efficiency of bottle mouth recognition.
[0075] In some optional embodiments, the control method of the drinking water device further includes: dividing the area between the water outlet and the water receiving container receiving base according to a preset height to obtain a plurality of sub-areas. Figure 2 As shown, the preset height represents the distribution height of the sub-area, which can be understood as a division every time a preset height is set, and each sub-area is at a different height, and each sub-area corresponds to a height. For example, the area S between the water outlet and the base of the water receiving container is divided into S1, S2, ..., S m equal area, m represents the number of divisions, S m It represents the sub-area closest to the water outlet. The upper height of each area is H1, H2, ..., H m .
[0076] Furthermore, the above step S101 includes:
[0077] Step S201, determining the temperatures of multiple sub-areas.
[0078] The above step S102 includes:
[0079] Step S202, determining the position of the bottle mouth of the water receiving container according to the temperatures of the multiple sub-areas.
[0080] The area between the water outlet and the receiving base has been divided into multiple sub-areas according to preset heights. After the area between the water outlet and the receiving base is divided into multiple sub-areas, the temperature conditions of each sub-area can be determined by detecting the temperature distribution in the area. By analyzing the temperature data of each sub-area, the areas with obvious temperature changes can be further determined. These areas may indicate the heat exchange boundary between the liquid inside the water receiving container and the external environment. Based on the analysis of temperature differences, combined with the preset judgment method, the bottle mouth position of the water receiving container can be inferred, and specifically the sub-area to which the bottle mouth position belongs can be determined.
[0081] In some optional implementations, the above step S202 includes:
[0082] Step S2021, calculating the temperature difference between each adjacent sub-area at the same time.
[0083] When detecting the temperature, detection may be performed periodically based on a preset time interval, so that the temperature of each sub-area at each temperature detection moment may be determined, based on which the temperature difference between each adjacent sub-area is calculated.
[0084] For example, the temperatures of each sub-region at time t1 are T 11 , T 21 ,…,T m1 , the temperature of each sub-area at time t2 is T 12 , T 22 ,…,T m2 ;…;t n The temperature of each sub-area detected at the moment is T 1n , T 2n ,…,T mn . n For example, the temperature difference between adjacent sub-areas is T 2n -T 1n ,……,T mn -T (m-1)n .
[0085] Step S2022: If the temperature difference satisfies the preset temperature condition, the sub-region close to the receiving base in the adjacent sub-regions corresponding to the temperature difference is determined as the bottle mouth position of the water receiving container.
[0086] The adjacent sub-regions corresponding to the temperature difference include two adjacent sub-regions, that is, the sub-region closer to the receiving base in the two sub-regions corresponding to each temperature difference is the bottle mouth position of the water receiving container.
[0087] Specifically, the preset temperature conditions include two situations. The first is that the preset temperature condition is that the absolute value of the temperature difference is greater than the preset temperature difference threshold; the second is that the absolute value of the temperature difference is greater than the preset temperature difference threshold and the number of times the absolute value of the temperature difference is greater than the preset temperature difference threshold reaches a first preset number, and the first preset number is greater than 1.
[0088] When the preset temperature condition is the first one, when it is detected that the absolute value of the temperature difference corresponding to two adjacent sub-areas is greater than the preset temperature difference threshold, the sub-area closer to the receiving base is determined to be the bottle mouth position.
[0089] When the preset temperature condition is the second one, if it is detected that the absolute value of the temperature difference corresponding to two adjacent sub-areas is greater than the preset temperature difference threshold, and it is detected multiple times, the sub-area closer to the receiving base is determined as the bottle mouth position. The specific first preset number of times can be set according to actual needs.
[0090] The preset temperature difference threshold can be set according to the gear corresponding to the outlet water temperature. For example, if the outlet water gear of the drinking water device can be divided into hot water, warm water and cold water according to the temperature, each temperature has a corresponding preset temperature difference threshold. In addition, it can also be set according to the external environment temperature and the current outlet water temperature.
[0091] For example, taking the second preset temperature condition as an example, if S is detected a times, m With S m-1 The absolute temperature difference of the region|(T mn -T (m-1)n )|> preset temperature difference threshold, then determine S m-1 The area is the bottle mouth of the water receiving container.
[0092] In some optional embodiments, the preset temperature difference threshold is determined as follows: obtain the ambient temperature and the outlet water temperature; obtain the preset temperature difference threshold based on the difference between the ambient temperature and the outlet water temperature, wherein the preset temperature difference threshold is positively correlated with the difference and is smaller than the difference.
[0093] The ambient temperature refers to the external ambient temperature, the outlet water temperature refers to the temperature of the water flowing out of the outlet, and the preset temperature difference threshold is the difference between the ambient temperature and the outlet water temperature multiplied by a correction coefficient less than 1.
[0094] In this embodiment, the preset temperature difference threshold can be adaptively determined according to the difference between the ambient temperature and the outlet water temperature, so as to avoid the situation where the bottom area of a glass cup, a plastic cup or other cup with good thermal conductivity detects that the temperature of the adjacent area is greater than the preset temperature difference threshold when high-temperature water flows to the bottom of the cup.
[0095] In some optional implementations, the above step S202 includes:
[0096] Step S2023, determining the sub-region with the highest temperature among the sub-regions at the same time.
[0097] The temperature of each sub-region at each detection moment is obtained, and the sub-region with the highest temperature among the sub-regions at each detection moment is determined.
[0098] Step S2024: If the number of times that the first sub-region has the highest temperature reaches a second preset number of times, a second sub-region adjacent to the first sub-region is determined as the bottle mouth position of the water receiving container.
[0099] The second sub-area is closer to the receiving base than the first sub-area, and the second preset number is greater than 1.
[0100] If there is a first sub-region that is the sub-region with the highest temperature for multiple times, a second sub-region adjacent to the first sub-region and closer to the receiving base is determined as the bottle mouth position of the water receiving container.
[0101] For example, if the area is divided into 4 sub-areas, the temperature of each sub-area recorded at time t1 is T 11 , T 21 , T 31 , T 41 ; The temperature of each sub-area at time t2 is T 12 , T 22 , T 32 , T 42 ;t n The temperature of each sub-area at the moment T 1n , T 2n , T 3n , T 4n If at t n Within the time, if the temperature of area S4 is detected to be the highest b times, S3 is determined to be the second sub-area, that is, the bottle mouth position of the water receiving container, wherein b times represents the second preset number of times.
[0102] In some optional embodiments, after determining the position of the bottle mouth of the water receiving container, as Figure 3 As shown, the method also includes the following steps:
[0103] Step S301, obtaining the temperature change of the water receiving container, and judging whether the current water level of the water receiving container reaches the bottle mouth position based on the temperature change.
[0104] Since the water receiving container has different materials and characteristics, when water contacts the container, the temperature of the container will change due to the thermal conductivity of water. As water continues to flow out of the water outlet, the water level of the water receiving container rises, and more water contacts the water receiving container, causing the temperature change of the cup wall to become more obvious. By detecting the temperature distribution, the temperature change of the water receiving container can be determined.
[0105] When the temperature change detection starts, the reference temperature is needed as a reference. The reference temperature can be the temperature of the container when it is completely dry (without water). As water is added, the temperature of the container surface will change. When the temperature change reaches a certain preset threshold, which corresponds to the temperature change at the bottle mouth, it can be considered that the current water level has reached the bottle mouth.
[0106] Step S302: When the current water level reaches the bottle mouth, the drinking water device is controlled to stop discharging water.
[0107] When it is determined through temperature changes that the water level in the water receiving container reaches the bottle mouth, the drinking water device is controlled to stop discharging water.
[0108] This step can prevent water from overflowing the water collection container, and automatically stop the water supply when the water level reaches the bottle mouth, thereby improving the user experience.
[0109] In some optional embodiments, step S301 includes: obtaining a first temperature change rate of the sub-area where the bottle mouth is located, and if the first temperature change rate is greater than a first preset temperature change rate threshold, determining that the current water level of the water receiving container has reached the bottle mouth.
[0110] By regularly testing the temperature in the area between the water outlet and the base of the water receiving container, the temperature of each sub-area at each testing moment can be determined, and the temperature change amount and temperature change rate compared with the temperature at the previous testing moment can also be calculated.
[0111] For example, at t n Moment, S m Temperature change rate of the region A mn for:
[0112]
[0113] Among them, Δt n Indicates the temperature change, T m(n-1) Indicates S m Area in T n-1 Temperature at the moment, T mn Indicates S m Area in t n The temperature of the moment.
[0114] The first preset temperature change rate threshold is a preset temperature threshold used to determine whether the temperature change is significant, and needs to be set according to actual conditions (such as container material, ambient temperature, water temperature, etc.). When the first temperature change rate is greater than the preset temperature change rate threshold, it means that the current water level has reached the bottle mouth position.
[0115] In some optional embodiments, step S301 includes: obtaining a second temperature change rate of a sub-area adjacent to the sub-area where the bottle mouth position is located and below the bottle mouth position, and if the second temperature change rate changes from greater than a first preset temperature change rate threshold to less than the first preset temperature change rate threshold, it is determined that the current water level of the water receiving container has reached the bottle mouth position.
[0116] By regularly testing the temperature in the area between the water outlet and the base of the water container, the temperature of each divided sub-area at each testing moment can be determined, and the temperature change and temperature change rate of each testing moment compared with the temperature at the previous testing moment can also be calculated. In the process of water level rising, as the water gradually covers, the temperature of different sub-areas will change. For a sub-area, if the water level does not reach the sub-area and gradually immerses the sub-area, the temperature change rate will change.
[0117] When it is detected that the second temperature change rate changes from being greater than the first preset temperature change rate threshold to being less than the first preset temperature change rate threshold, this means that as the water level rises, the rapid temperature change (i.e., the temperature change rate is large) originally caused by the temperature difference between air and water is weakened after the water level covers the sub-area (because the sub-area is already covered by water at this time, the temperature difference between water and water is small, and the temperature change rate is therefore smaller). This change indicates that the water level has reached or is about to reach the bottle mouth position.
[0118] In some optional implementations, step S301 includes the following steps:
[0119] Step S3011, obtaining a third temperature change rate of the bottom sub-region.
[0120] The bottom sub-area is the sub-area closest to the receiving base. The temperature in the area between the water outlet and the receiving base of the water container is regularly detected to determine the temperature of each divided sub-area at each detection moment, and the temperature change amount and temperature change rate compared with the temperature at each detection moment and the previous detection moment can also be calculated. The third temperature change rate represents the temperature change rate of the bottom sub-area, and the third temperature change rate of the bottom sub-area is calculated at each detection moment.
[0121] As an example, after the water supply of the drinking water device has been turned on for 3 seconds, the third temperature change rate A of the bottom sub-area at time t2 can be calculated. 12 .
[0122] Step S3012: determining the thermal insulation capacity of the water receiving container based on the magnitude relationship between the third temperature change rate and the second preset temperature change rate threshold.
[0123] The second preset temperature change rate threshold is a preset value used to evaluate the thermal insulation performance of the water receiving container.
[0124] Specifically, step S3012 includes: when the third temperature change rate is greater than the second preset temperature change rate threshold, the thermal insulation capacity of the water receiving container is weak; when the third temperature change rate is less than the second preset temperature change rate threshold, the thermal insulation capacity of the water receiving container is strong.
[0125] If the third temperature change rate is greater than the second preset temperature change rate threshold, it means that the heat exchange between the bottom of the water receiving container and the external environment is fast and the heat insulation capacity is weak.
[0126] If the third temperature change rate is less than the second preset temperature change rate threshold, it means that the bottom of the water receiving container can effectively isolate the temperature change of the external environment and has a strong heat insulation ability.
[0127] Step S3013, when the heat insulation capacity of the water receiving container is strong, select to obtain the first temperature change rate of the sub-area where the bottle mouth position is located. If the first temperature change rate is greater than the first preset temperature change rate threshold, it is determined that the current water level of the water receiving container has reached the bottle mouth position.
[0128] The first temperature change rate refers to the change rate of the temperature of the sub-area where the bottle mouth is located. In the case of strong insulation, the temperature inside the water receiving container is less affected by the external environment. Therefore, the temperature change rate at the bottle mouth can be monitored to accurately determine whether the water level has reached the bottle mouth. If the first temperature change rate is greater than the preset temperature change rate threshold (possibly due to the temperature change caused by the rising water level), it is determined that the current water level has reached the bottle mouth.
[0129] Step S3014, when the thermal insulation capacity of the water receiving container is weak, select to obtain the second temperature change rate of the sub-area adjacent to the sub-area where the bottle mouth position is located and below the bottle mouth position. If the second temperature change rate changes from being greater than the first preset temperature change rate threshold to being less than the first preset temperature change rate threshold, it is determined that the current water level of the water receiving container has reached the bottle mouth position.
[0130] The second temperature change rate represents the rate at which the temperature changes over time in the sub-area adjacent to and below the bottle mouth position. When the thermal insulation capacity is weak, the temperature inside the container is easily affected by the external environment, so directly monitoring the temperature change rate at the bottle mouth position may not be accurate enough. At this time, by monitoring the temperature change rate of the sub-area adjacent to and below the bottle mouth position (this area will be covered by water first when the water level rises, resulting in temperature changes), it is possible to more accurately determine whether the water level has reached the bottle mouth. If the second temperature change rate changes from being greater than the first preset temperature change rate threshold to being less than the first preset temperature change rate threshold (indicating that the area is changed from being covered by air to being covered by water, and the temperature change rate is therefore reduced), it is determined that the current water level has reached the bottle mouth position.
[0131] In some optional embodiments, Figure 1In the corresponding control method of the drinking water equipment, after determining the position of the bottle mouth of the water receiving container, the method further includes:
[0132] Step S401, obtaining a first distance between the current water level of the water receiving container and the water outlet;
[0133] The drinking water device of this embodiment is also provided with a distance measuring device, which is arranged beside the water outlet. The distance measuring device can be a distance measuring sensor, specifically an ultrasonic sensor, an infrared sensor, a laser sensor, etc. The distance measuring device can detect the distance between the current water level in the water receiving container and the water outlet, i.e., the first distance.
[0134] Step S402, calculating a second distance between the water outlet and the bottle mouth of the water receiving container.
[0135] After the position of the bottle mouth is determined, the distance between the water outlet and the bottle mouth, that is, the second distance, can be measured by the distance measuring device. Both the first distance and the second distance are vertical distances.
[0136] Step S403, judging whether the current water level of the water receiving container reaches the bottle mouth position according to the first distance and the second distance.
[0137] By comparing the first distance and the second distance, it can be determined whether the current water level has reached the bottle mouth position. If the first distance is less than or equal to the second distance, it can be considered that the current water level has reached the bottle mouth position.
[0138] Step S404, when the current water level reaches the bottle mouth position, control the drinking water device to stop discharging water.
[0139] When it is determined that the current water level has reached the bottle mouth position, the drinking water device is controlled to stop discharging water to prevent water from overflowing the container.
