Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, and particularly provides a water purification and drinking equipment and a control method thereof. BACKGROUND

[0002] With the improvement of people's living standards, people's demand for drinking water is also getting higher and higher. Water purification and drinking equipment such as water purifiers and pipeline machines gradually become essential drinking water facilities in people's daily life.

[0003] In the installation-free water purification and drinking machine, a water purification tank is usually arranged to store purified water. In order to facilitate the smooth discharge of purified water, an exhaust port is usually arranged on the water purification tank to allow air to enter. The arrangement of the exhaust port will cause external air to enter the water purification tank, and dust, bacteria and other substances in the air will cause secondary pollution of the water purification tank, resulting in a large number of bacteria breeding in the water purification tank. Since the water purification tank is generally placed inside the water purification and drinking machine, and many probes are also installed on the water purification tank, it is generally forbidden to disassemble, so that the cleaning of the water purification tank is very difficult.

[0004] At the same time, for the water purifier with a cold tank, the water tank cold tank in the water purification tank is replenished with water, and the bacteria breeding in the water purification tank will also affect the water quality in the cold tank. Although the existing water purification and drinking equipment can sterilize the water purification tank by high-temperature sterilization, it still cannot effectively sterilize the cold tank, resulting in poor water quality in the cold tank and affecting the user's experience. SUMMARY

[0005] The present application aims to at least partially solve the above technical problems, i.e., at least partially solve the problem that the existing water purification and drinking equipment cannot effectively sterilize the water purification tank and the cold tank, thereby affecting the user's experience.

[0006] In a first aspect, the present application provides a water purification and drinking equipment having a water storage cavity and a cold water cavity, the water purification and drinking equipment comprising a heating member and a pump assembly, a first circulation loop being formed between the water storage cavity and the heating member, a second circulation loop being formed between the water storage cavity and the cold water cavity, the heating member being capable of heating water in the first circulation loop when the water purification and drinking equipment executes a sterilization mode, the pump assembly being arranged to enable the water in the water storage cavity to circulate in the first circulation loop to sterilize the first circulation loop, and the pump assembly being further arranged to enable the hot water in the water storage cavity to circulate in the second circulation loop to sterilize the second circulation loop.

[0007] In the preferred technical scheme of the above-mentioned pure drinking device, the pure drinking device comprises a first pipeline, a second pipeline, a third pipeline and a water outlet member, the first pipeline is used for connecting the water storage cavity and the water inlet end of the heating member, the second pipeline is used for connecting the water storage cavity and the water inlet end of the cold water cavity, the water outlet end of the cold water cavity and the water outlet end of the heating member are both connected with the first end of the third pipeline, and the second end of the third pipeline can selectively communicate with the water storage cavity or the water outlet member; wherein the water storage cavity, the first pipeline, the heating member and the third pipeline are sequentially connected to form the first circulation loop, and the water storage cavity, the second pipeline, the cold water cavity and the third pipeline are sequentially connected to form the second circulation loop.

[0008] In the preferred technical scheme of the above-mentioned pure drinking device, the pure drinking device further comprises a reversing valve, the first interface of the reversing valve is connected with the second end of the third pipeline, the second interface of the reversing valve is connected with the water outlet member, and the third interface of the reversing valve is connected with the water storage cavity, and the first interface can selectively communicate with the second interface or the third interface.

[0009] In the preferred technical scheme of the above-mentioned pure drinking device, the pump assembly comprises a first pump body and a second pump body, the first pump body is arranged on the first circulation loop and is used for circulating the water in the water storage cavity in the first circulation loop, and the second pump body is arranged on the second circulation loop and is used for circulating the water in the water storage cavity in the second circulation loop.

[0010] In the preferred technical scheme of the above-mentioned pure drinking device, the pure drinking device further comprises a water inlet control valve and a cold water outlet pipeline, the water inlet control valve is arranged on the second pipeline and is used for controlling the opening and closing of the second pipeline, the cold water outlet pipeline is used for connecting the water outlet end of the cold water cavity and the first end of the third pipeline, and the second pump body is arranged on the cold water outlet pipeline.

[0011] In the second aspect, the application further provides a control method for a pure drinking device, wherein the pure drinking device is any one of the above-mentioned pure drinking devices, and the control method comprises the following steps: detecting whether there is water in the cold water cavity; in the case that there is water in the cold water cavity, obtaining the water level L in the water storage cavity; and selectively emptying the water in the cold water cavity according to the water level L.

[0012] In the preferred technical scheme of the above-mentioned control method for a pure drinking device, the step of "selectively emptying the water in the cold water cavity according to the water level L" specifically comprises: judging whether the water level L reaches a preset water level L0; and selectively emptying the water in the cold water cavity according to the judgment result.

[0013] In the preferred technical solution of the control method for the water purification and drinking device, the step of selectively emptying the water in the cold water cavity according to the judgment result specifically comprises: if the judgment result is yes, the water in the cold water cavity is emptied; and / or if the judgment result is no, the water in the cold water cavity is not emptied.

[0014] In the preferred technical solution of the control method for the water purification and drinking device, in the case where the judgment result is no, the control method further comprises: delivering the water in the cold water cavity into the water storage cavity.

[0015] In the preferred technical solution of the control method for the water purification and drinking device, the step of delivering the water in the cold water cavity into the water storage cavity specifically comprises: obtaining the water amount Q in the cold water cavity; determining a target water delivery amount Q0 according to the water amount Q, the water level L and the preset water level L0; and delivering the water in the cold water cavity into the water storage cavity according to the target water delivery amount Q0.

[0016] In the case of adopting the preferred technical solution, by forming the first circulation loop between the water storage cavity and the heating member, the water in the water storage cavity can be heated by the heating member and the hot water can circulate in the first circulation loop, thereby facilitating high-temperature sterilization of the first circulation loop. By forming the second circulation loop between the water storage cavity and the cold water cavity, the hot water in the water storage cavity can circulate in the second circulation loop, thereby facilitating high-temperature sterilization of the second circulation loop. In this way, full-pipeline sterilization of the water purification and drinking device can be achieved, greatly improving the user's experience.

[0017] Further, by setting the water purification and drinking device such that the water storage cavity, the first pipeline, the heating member and the third pipeline are sequentially communicated to form the first circulation loop, and the water storage cavity, the second pipeline, the cold water cavity and the third pipeline are sequentially communicated to form the second circulation loop, the first circulation loop and the second circulation loop can share the third pipeline, simplifying the pipeline connection. By setting the second end of the third pipeline to be selectively communicated with the water storage cavity or the water outlet member, the water purification and drinking device can be conveniently switched between the water taking mode and the sterilization mode, further improving the user's experience.

[0018] Still further, compared with the way of setting the first control valve and the second control valve on the water outlet pipe and the return pipe, the form of setting the reversing valve can further simplify the connection of the pipeline, and facilitate convenient switching of the water purification and drinking device between the sterilization mode and the water outlet mode, further improving the user's experience.

[0019] Further, the water storage cavity can be replenished with water by the water inlet control valve, and the first pump body is arranged on the cold water outlet pipeline, so that the water in the cold water cavity can be easily pumped out to achieve cold water outlet. In this way, the cold water in the cold water cavity can be completely used up before the water inlet electromagnetic valve is started to replenish the cold water cavity with water, thereby solving the problem of mixing water caused by directly replenishing the cold water cavity with water after the cold water is taken out in the prior art, and the problem of large temperature deviation of the water in the cold water cavity.

[0020] In addition, the control method for the water purification device is provided on the basis of the above-mentioned water purification device. By detecting whether there is water in the cold water cavity, if there is water in the cold water cavity, the water level L in the water storage cavity is obtained. Whether the water in the water storage cavity has sufficient water for sterilization can be determined according to the water level L. On the one hand, if there is sufficient water in the water storage cavity for sterilization, the water in the cold water cavity can be emptied to avoid the problems of energy waste and long sterilization time caused by the need to heat the excess cold water in the cold water cavity. On the other hand, if there is not enough water in the water storage cavity for sterilization, the water in the cold water cavity is not emptied, which can avoid the problem of poor sterilization effect caused by insufficient sterilization water, and further improve the user experience.

[0021] Further, compared with the form of first calculating the difference between the water level L and the preset water level, and then comparing the difference with the preset value, and selectively emptying the water in the cold water cavity according to the comparison result, the way of judging whether the water level L reaches the preset water level L0 can more intuitively determine whether the water level L meets the water level height for sterilization, so that whether the water in the cold water cavity needs to be emptied can be more intuitively and accurately determined.

[0022] Further, if the judgment result is "yes", it means that the water level in the water storage cavity can reach the preset water level L0, that is, there is sufficient sterilization water in the water storage cavity. At this time, the water in the cold water cavity is emptied to avoid the problems of energy waste and long sterilization time caused by the need to heat the excess cold water in the cold water cavity during sterilization, and to avoid affecting the user experience. If the judgment result is "no", it means that the water level L in the water storage cavity has not reached the preset water level L0, that is, there is not enough sterilization water in the water storage cavity. At this time, the water in the cold water cavity is not emptied to avoid the problem of insufficient sterilization water caused by insufficient water in the water storage cavity, thereby avoiding the influence of the sterilization effect caused by insufficient water.

[0023] Further, if the judgment result is "no", it means that the water in the water storage cavity does not meet the sterilization water amount. At this time, the water in the cold water cavity is transported to the water storage cavity, so that there is sufficient sterilization water in the water storage cavity, which can facilitate the implementation of first starting the first pump body to sterilize the first circulation loop, thereby avoiding the influence of the sterilization effect of the first circulation loop caused by insufficient water in the water storage cavity.

[0024] Further, by the water level in the water storage cavity, the preset water level and the water amount information in the cold water cavity, the target water delivery amount from the cold water cavity to the water storage cavity can be determined more accurately. On the one hand, the water amount delivered from the cold water cavity to the water storage cavity can be prevented from being too small to meet the water amount for sterilization, thereby avoiding affecting the sterilization effect. On the other hand, the water amount delivered from the cold water cavity to the water storage cavity can be prevented from being too large to cause excessive water amount in the water storage cavity, thereby avoiding problems such as energy waste and long sterilization time due to excessive water amount for sterilization.

[0079] It should be noted that the present application does not make any limitation on the specific detection method for detecting whether there is water in the cold water cavity 20, as long as it can detect whether there is water in the cold water cavity 20. For example, the water level in the cold water cavity 20 can be detected, and whether there is water in the cold water cavity 20 can be detected according to the water level, or the actual water amount in the cold water cavity 20 can be detected, and whether there is water in the cold water cavity 20 can be detected according to the actual water amount, or the image in the cold water cavity 20 can be photographed, and the image in the cold water cavity 20 can be compared with the target image, and whether there is water in the cold water cavity 20 can be detected according to the comparison result, and the like. The adjustment and change of the specific detection method for detecting whether there is water in the cold water cavity 20 do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0080] Preferably, the step of "detecting whether there is water in the cold water cavity 20" specifically comprises:

[0081] Obtaining the actual water amount in the cold water cavity 20;

[0082] If the actual water amount is greater than or equal to the preset water amount, it indicates that there is water in the cold water cavity 20;

[0083] If the actual water amount is less than the preset water amount, it indicates that there is no water in the cold water cavity 20.

[0084] It should be noted that the actual water amount in the cold water cavity 20 can be obtained by reading the scale on the side wall of the cold water cavity, or a water level detection member can be arranged in the cold water cavity 20, the water level in the cold water cavity 20 can be detected by the water level detection member, and the actual water amount in the cold water cavity 20 can be calculated according to the water level, and the like. The adjustment and change of the specific acquisition method of the actual water amount in the cold water cavity 20 do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0085] Exemplarily, the actual water amount in the cold water cavity 20 is obtained by reading the scale on the side wall of the cold water cavity 20.

[0086] It should be noted that the specific value of the preset water amount can be determined by experience or experiment by those skilled in the art.

[0087] Exemplarily, the preset water amount is 0.

[0088] It should be noted that, the actual water amount is not limited to be compared with the preset water amount, and whether there is water in the cold water cavity 20 is detected according to the comparison result, for example, the difference between the actual water amount and the preset water amount can be calculated, and then the difference is compared with a preset value, if the difference is greater than the preset value, it indicates that there is water in the cold water cavity 20, if the difference is less than the preset value, it indicates that there is no water in the cold water cavity 20, and the like, such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application. Of course, preferably, the actual water amount is compared with the preset water amount, and whether there is water in the cold water cavity 20 is detected according to the comparison result.

[0089] It should be noted that, in actual application, a water level detection member can be arranged in the water storage cavity 10, the water level L in the water storage cavity 10 is obtained through the detection value of the water level detection member, or a scale can be arranged on the side wall of the water storage cavity 10, the water level L in the water storage cavity 10 is obtained according to the scale, or a communication pipe in communication with the water storage cavity 10 can be arranged, the water level L in the water storage cavity 10 is obtained by detecting the water level in the communication pipe, and the like, such adjustment and change of the specific obtaining mode of the water level L in the water storage cavity 10 does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0090] Preferably, the pure drinking device of the present application further comprises a water level detection member (not shown in the figure) arranged in the water storage cavity 10,

[0091] The step of "obtaining the water level L in the water storage cavity 10" specifically comprises:

[0092] The water level L in the water storage cavity 10 is obtained according to the detection value of the water level detection member.

[0093] It should be noted that, in actual application, the water in the cold water cavity 20 can be selectively emptied according to the water level L and combined with experience, or whether the water level L reaches a preset water level L0 can be judged, and the water in the cold water cavity 20 is selectively emptied according to the judgment result, and the like, such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0094] Preferably, as Figure 5 shown, the step of "selectively emptying the water in the cold water cavity 20 according to the water level L" specifically comprises:

[0095] S31: judging whether the water level L reaches a preset water level L0;

[0096] S32: selectively emptying the water in the cold water cavity 20 according to the judgment result.

[0097] Through such a setting, it can be more intuitive to determine whether the water level L meets the water level height for sterilization, so that it can be more intuitive and more accurate to determine whether the water in the cold water cavity 20 needs to be emptied.

[0098] It should be noted that it is not limited to determining whether the water level L reaches the preset water level L0, and selectively emptying the water in the cold water cavity 20 according to the determination result, or the difference between the water level L and the preset water level L0 can be calculated first, and then the difference is compared with the preset value, and according to the comparison result, the water in the cold water cavity 20 is selectively emptied, or the ratio of the water level L and the preset water level L0 can be calculated first, and then the ratio is compared with the preset value, and according to the comparison result, the water in the cold water cavity 20 is selectively emptied, and so on. Such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application. Of course, preferably, whether the water level L reaches the preset water level L0 is determined, and the water in the cold water cavity 20 is selectively emptied according to the determination result.

[0099] Next, refer to Figure 5 , Figure 5 is a flow chart of an embodiment of the control method for the net drinking device of the present application.

[0100] Preferably, as Figure 5 indicated, the step of "selectively emptying the water in the cold water cavity 20 according to the determination result" specifically includes:

[0101] S321: If the determination result is "yes", the water in the cold water cavity 20 is emptied.

[0102] Through such a setting, in the case where the determination result is "yes", it indicates that the water level in the water storage cavity 10 can reach the preset water level L0, that is, there is sufficient water for sterilization in the water storage cavity 10, at this time, the water in the cold water cavity 20 is emptied, which can avoid the problems of energy waste and too long sterilization time caused by the need to heat the excess cold water in the cold water cavity 20 during sterilization, and avoid affecting the user's experience.

[0103] Preferably, as Figure 5 indicated, the step of "selectively emptying the water in the cold water cavity 20 according to the determination result" specifically includes:

[0104] S322: If the determination result is "no", the water in the cold water cavity 20 is not emptied.

[0105] Through such a setting, in the case where the determination result is "no", it indicates that the water level L in the water storage cavity 10 has not reached the preset water level L0, that is, there is not enough water for sterilization in the water storage cavity 10, at this time, the water in the cold water cavity 20 is not emptied, which can avoid the problem of affecting the sterilization effect caused by the insufficient water in the water storage cavity 10 during sterilization.

[0106] It should be noted that when the water purification device performs the sterilization mode, the first pump body 41 can be started first, so that the water in the water storage cavity 10 circulates in the first circulation loop and the water in the first circulation loop is heated by the heating member 3, that is, the first circulation loop is sterilized first, and then the second pump body 42 is started, so that the water in the water storage cavity 10 circulates in the second circulation loop, thereby sterilizing the second circulation loop, or the first pump body 41 and the second pump body 42 can be started at the same time, so that the water in the water storage cavity 10 circulates in the first circulation loop and the second circulation loop at the same time, that is, the first circulation loop and the second circulation loop are sterilized at the same time, and the like. The adjustment and change of the specific mode of sterilizing the first circulation loop and the second circulation loop do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0107] Preferably, when the water purification device performs the sterilization mode, the control method of the present application further comprises:

[0108] The first pump body 41 is started first, so that the water in the water storage cavity 10 circulates in the first circulation loop and the water in the first circulation loop is heated by the heating member 3, and when the circulation time reaches the preset time, the second pump body 42 is started, so that the water in the water storage cavity 10 circulates in the second circulation loop.

[0109] Through such a setting, the first pump body 41 can be started first, so that the water temperature in the first circulation loop rapidly rises to the sterilization water temperature, thereby improving the sterilization efficiency, reducing the sterilization time, and further reducing the waiting time of the user, and improving the user's use experience.

[0110] Preferably, as shown in Figure 5 When the judgment result is "no", the control method of the present application further comprises the following steps:

[0111] S4: Delivering the water in the cold water cavity 20 to the water storage cavity 10.

[0112] Through such a setting, when the judgment result is "no", it means that the water in the water storage cavity 10 does not meet the sterilization water amount, at this time, the water in the cold water cavity 20 is delivered to the water storage cavity 10, so that there is sufficient water for sterilization in the water storage cavity 10, which can facilitate the first pump body 41 to be started first to sterilize the first circulation loop, thereby avoiding the influence of the sterilization effect of the first circulation loop due to the insufficient water amount in the water storage cavity 10.

[0113] It should be noted that in actual application, the water in the cold water cavity 20 can be transported into the water storage cavity 10 according to experience of the person skilled in the art, or the water amount in the cold water cavity 20 can be obtained first, and then the target water transport amount Q0 is determined according to the water amount, the water level L in the water storage cavity 10 and the preset water level L0, and the water in the cold water cavity 20 is transported into the water storage cavity 10 according to the target water transport amount Q0, and so on.

On the one hand, it can avoid that the water amount transported from the cold water cavity 20 to the water storage cavity 10 is too small to cause that the water amount in the water storage cavity 10 cannot meet the water amount for sterilization, thereby avoiding affecting the sterilization effect. On the other hand, it can also avoid that the water amount transported from the cold water cavity 20 to the water storage cavity 10 is too large to cause that the water amount in the water storage cavity 10 is too much, thereby avoiding the problems of energy waste and long sterilization time caused by too much sterilization water amount.

[0119] Preferably, the step of "determining the target water transport amount Q0 of the cold water cavity 20 to the water storage cavity 10 according to the water level L, the preset water level L0 and the water amount Q" specifically comprises:

[0121] comparing the water amount difference AQ with the water amount Q;

[0122] determining the target water transport amount Q0 according to the comparison result.

[0123] Through such a setting, that is, by comparing the water amount difference AQ in the water storage cavity 10 with the water amount Q, and determining the target water transport amount Q0 according to the comparison result, the target water transport amount Q0 can be more accurately determined.

[0124] It should be noted that in actual application, the corresponding relationship between the difference AL between the water level L and the preset water level L0 and the target water delivery amount Q0 can be established first, and then the water amount difference AQ can be calculated according to the water level L and the preset water level L0 through table lookup, or the water amount difference AQ can be calculated according to the cross-sectional area S of the water storage cavity and the water level L and the preset water level L0, and the like. The adjustment and change of the calculation method of the water amount difference AQ do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0125] Preferably, the step of calculating the water amount difference AQ according to the water level L and the preset water level L0 specifically comprises:

[0126] calculating the water level difference AL = L - L0;

[0127] calculating AQ by the following formula:

[0128] AQ = (L - L0) * S

[0129] wherein S is the cross-sectional area of the water storage cavity.

[0130] Preferably, the step of determining the target water delivery amount Q0 according to the comparison result specifically comprises:

[0131] if AQ ≤ Q, then the target water delivery amount Q0 is AQ.

[0132] Through such a setting, in the case of AQ ≤ Q, it is indicated that the water amount difference AQ does not exceed the actual water amount Q in the cold water cavity 20, and in this case, only part of the water in the cold water cavity 20 needs to be delivered to the water storage cavity 10 to make the water storage cavity 10 have sufficient water for sterilization, that is, the water amount of the target water delivery amount AQ can make the water storage cavity 10 have sufficient water for sterilization.

[0133] Preferably, the step of determining the target water delivery amount Q0 according to the comparison result specifically comprises:

[0134] if AQ > Q, then the target water delivery amount Q0 is Q.

[0135] Through such a setting, in the case of AQ > Q, it is indicated that the water amount difference AQ exceeds the actual water amount Q in the cold water cavity 20, and in this case, delivering all the water in the cold water cavity 20 to the cold water cavity 20 still cannot make the water storage cavity 10 have sufficient water for sterilization, that is, setting the target water delivery amount as Q can deliver as much water as possible in the cold water cavity 20 to the water storage cavity 10 for sterilization.

[0136] It should be noted that the water in the cold water cavity 20 can be delivered to the water storage cavity 10 by sending a reminder to the user, or the water in the cold water cavity 20 can be delivered to the water storage cavity 10 by starting the second pump body 42, and the like. The adjustment and change of the specific delivery mode of the water in the cold water cavity 20 to the water storage cavity 10 do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0137] Preferably, the water in the cold water cavity 20 is delivered to the water storage cavity 10 by starting the second pump body 42.

[0138] Preferably, the pure drinking device of the present application further comprises a flow detection member 551, which is arranged on the cold water outlet pipe 55.

[0144] Preferably, as shown in ​ The step of "selectively reminding the user according to the determination result" specifically comprises:

[0145] S61: if the determination result is "yes", the user is not reminded.

[0146] Through such an arrangement, in the case where the determination result is "yes", it indicates that the current water level in the water storage cavity 10 has reached the preset water level, and at this time, there is sufficient water for sterilization in the water storage cavity 10, so there is no need to remind the user.

[0147] Preferably, as shown in ​ The step of "selectively reminding the user according to the determination result" specifically comprises:

[0148] S62: if the determination result is "no", the user is reminded.

[0149] By such an arrangement, in the case where the determination result is "No", it indicates that the water amount in the water storage cavity 10 has not yet reached the preset water level, at which time a reminder is issued to the user, so that the user can be timely reminded to add water to the water storage cavity 10, thereby avoiding the problem of affecting the sterilization effect due to insufficient water amount in the water storage cavity 10.

[0153] By such an arrangement, after the water in the cold water cavity 20 is delivered to the water storage cavity 10, it is further determined whether there is water in the cold water cavity 20, and then in the case where there is water in the cold water cavity 20, the water in the cold water cavity 20 is discharged, thereby avoiding the problems of energy waste and excessive sterilization time due to the need to heat the cold water in the cold water cavity 20 during sterilization, and further improving the user's experience.

[0154] It should be noted that the step of detecting whether there is water in the cold water cavity 20 is the same as the aforementioned detection step, which will not be described here.

[0155] It should be noted that the present application does not make any limitation on the specific emptying method for emptying the water in the cold water cavity 20, as long as the water in the cold water cavity 20 can be emptied. For example, the water dispenser can be provided with a drainage assembly, which is started to empty the water in the cold water cavity 20, or the water dispenser can be provided with a reminder device, which issues a reminder to the user to prompt the user to empty the water in the cold water cavity 20, etc. Such adjustments and changes to the specific emptying method for emptying the water in the cold water cavity 20 do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0162] By such an arrangement, compared with arranging the drain assembly in the form comprising the drain pipe 71 and the drain pump, arranging the drain assembly in the form comprising the drain pipe 71 and the drain electromagnetic valve 72 can avoid using the drain pump, thereby reducing the cost of the drain assembly, and further reducing the cost of the purified drinking equipment.
