Description

TECHNICAL FIELD

[0001] The present application relates to a stepless temperature-adjustable water purification output device and a control method thereof. BACKGROUND

[0002] Currently, in order to facilitate water taking, users of household water purifiers often use a set of water purification output devices in cooperation with the water purifiers. The water purification output devices generally consist of a faucet and a heating tank. The purified water output by the water purifier is input into the faucet and the heating tank, and the heated purified water in the heating tank is also input into the faucet. The faucet mixes the normal-temperature purified water and the heated purified water in different proportions according to the user's operation, so that the purified water output by the faucet can be steplessly temperature-adjusted for the user to take conveniently.

[0003] Due to the characteristics of high pressure and low flow rate of the purified water output by the household water purifier, in order to avoid the heating tank from bearing the water outlet pressure at all times, the output device often needs to be equipped with an electric control valve at the water inlet of the heating tank to limit the waterway on-off and thus protect the heating tank. In the case of needing to install an electric control valve in front of the heating tank, in order to achieve stepless temperature adjustment of the purified water output, an electric control valve with controllable opening degree needs to be arranged at the normal-temperature water inlet and the hot water inlet of the faucet respectively. Therefore, the knob / handle on the faucet of the output device often does not directly control the opening degree of each water inlet. The knob / handle is actually an electronic knob. The rotation of the knob / handle causes the change of voltage / current, and the control circuit controls the opening degree of the valves at the two water inlets according to the change of voltage / current, so as to mix the normal-temperature purified water and the heated purified water in different proportions to achieve stepless temperature adjustment of the purified water output.

[0004] However, the above-mentioned stepless temperature adjustment technology needs to use electric control valves with adjustable opening degree at the two water inlets of the faucet, and the knob / handle of the faucet also needs to be made into an electronic knob, so the cost is extremely high. In addition, due to the need to design and arrange the control circuit, the structure of the faucet also becomes more complex.

[0046] The net water output device directly controls the opening degree of the first water inlet 2 and the second water inlet 3 through the cooperation of the knob 7 and the valve core 6, so as to realize the mixing of normal temperature net water and hot net water. The opening and closing of the electromagnetic valve 5 is controlled through the cooperation of the control switch 8 and the trigger structure. When the rotating core of the valve core 6 and the knob 7 are rotated to a specified position range, that is, the opening degree of the first water inlet 2 and the second water inlet 3 reaches a specified condition, the trigger structure is also rotated to a specified position to trigger the control switch 8, so that the electromagnetic valve 5 can be controlled to be opened, and the normal temperature net water can enter the hot tank 4, and the hot net water in the hot tank 4 is delivered to the faucet.

[0047] As described above, the net water output device can control the electromagnetic valve 5 by setting the trigger structure on the rotating core of the valve core 6 or the knob 7 to cooperate with the control switch 8, and then control whether to input net water into the hot tank 4 for heating and storage. The valve core 6 and the knob 7 can realize the input and mixing of normal temperature net water and hot net water in different proportions, so as to realize stepless temperature adjustment. The present application does not need to use expensive electric control valves that can control the opening degree, does not need to change the faucet knob / handle into an electronic knob, and does not need to set a complex control circuit. Only by setting the trigger structure and the control switch 8 to cooperate with the traditional faucet structure, the stepless temperature adjustment net water output can be realized. Therefore, the technical scheme of the present application can greatly save the cost of parts compared with the prior art, and can simplify the product structure, thereby effectively improving the competitiveness of the product.

[0048] As Figures 2 to 3 shown, preferably, the trigger structure includes a rotating piece 9 fixed on the rotating core of the valve core 6 or the knob 7 and synchronously rotated.

[0050] As described above, the control switch 8 can be a contact switch. When the contact switch is used, the side surface of the rotating piece 9 is correspondingly set in a cam shape 91. When the rotating piece 9 is rotated with the rotating core or the knob 7, the cam structure can trigger the contact switch at a specified position to control the electromagnetic valve 5.

[0051] Preferably, the control switch 8 can also be a Hall switch, and the side surface of the rotating piece 9 is circumferentially provided with a magnet.

[0052] As described above, the control switch 8 can also be a Hall switch. When the Hall switch is used, a magnet is correspondingly arranged on the side surface of the rotating piece 9. When the rotating piece 9 is rotated with the rotating core or the knob 7 to a specified position, the magnet on the side surface of the rotating piece 9 can trigger the Hall switch to control the electromagnetic valve 5.

[0053] AsFigures 2 to 4 As shown in the figure, preferably, the faucet 1 is provided with a first temperature sensor 10 for detecting the temperature of the water outlet, and the faucet 1 is also provided with a display module 11 for displaying the temperature of the water outlet. In this way, the user can intuitively and accurately know the temperature of the water outlet of the faucet by detecting the temperature of the water outlet through the first temperature sensor 10 and displaying the temperature of the water outlet through the display module 11, thereby avoiding the user being scalded by the hot water flow or the temperature of the water outlet not meeting the user's requirements when the user does not know the temperature of the water outlet.

[0054] As shown in the figure, Figures 5 to 6 As shown in the figure, preferably, the hot tank 4 includes a tank body 41, the wall surface of the tank body 41 is provided with a heat insulation layer 42 for heat insulation and heat preservation, the tank body 41 is provided with a heating pipe 43 for heating the purified water, the tank body 41 is provided with a second mechanical temperature controller 44 for preventing dry burning, and the tank body 41 is also provided with a third mechanical temperature controller 45 or a fourth temperature sensor 48 for water temperature control.

[0055] As described above, the purified water input through the electromagnetic valve 5 enters the tank body 41, the purified water in the tank body 41 can be heated through the heating pipe 43, the third mechanical temperature controller 45 or the fourth temperature sensor 48 can more effectively control the start and stop of the heating pipe 43 according to the temperature of the purified water in the tank body 41, and the heat insulation layer 42 can avoid the rapid loss of heat in the tank body 41 to cause the heating pipe 43 to work frequently and increase energy consumption. In addition, the second mechanical temperature controller 44 can control the heating pipe 43 to stop working in time when dry burning occurs in the tank body 41.

[0056] As shown in the figure, Figures 5 to 6 As shown in the figure, preferably, the heat insulation layer 42 is filled with heat insulation material or the heat insulation layer 42 is a vacuum layer.

[0057] As shown in the figure, Figures 5 to 6 As shown in the figure, preferably, the heating pipe 43 and the second mechanical temperature controller 44 are arranged at the bottom of the tank body 41. In this way, when the water in the tank body 41 is less and the heating pipe 43 starts to dry, the heat generated by the heating pipe 43 can be quickly transmitted to the second mechanical temperature controller 44 to trigger the second mechanical temperature controller 44 to stop the heating pipe 43 from working.

[0058] As shown in the figure, Figure 5 As shown in the figure, preferably, the height position of the fourth temperature sensor 48 in the tank body 41 is consistent with the water level alarm water level of the tank body 41.

[0059] As mentioned above, when the water in the tank 41 gradually decreases due to heating and exceeds the alarm water level, the temperature detected by the fourth temperature sensor 48 will change, specifically, the temperature will suddenly drop, thus, the change of the temperature detected by the fourth temperature sensor 48 can be used to determine whether the water in the tank 41 is too little and below the alarm water level, so the fourth temperature sensor 48 also functions as a water level detector.

[0060] As shown in Figure 1 , Figure 5 , preferably, the top of the tank 41 is provided with an exhaust pipe 46, and the exhaust pipe 46 is provided with a pressure relief valve 47.

[0061] As shown in Figure 5 , preferably, the exhaust pipe 46 is a branch of the water path between the water outlet of the tank 41 and the second water inlet 3.

[0062] As mentioned above, when the heating pipe 43 heats the water in the tank 41, the air pressure in the tank 41 will also increase, and by setting the exhaust pipe 46 or the exhaust branch 48 in combination with the pressure relief valve 47, water vapor can be discharged through the pressure relief valve 47 when the pressure is too high, avoiding damage to the tank 41 due to excessive air pressure in the tank 41.

[0063] As shown in Figures 2 to 4 , preferably, the faucet 1 is provided with a fixed connecting seat 12, the fixed connecting seat 12 is provided with a containing cavity 121 with an opening upward for the valve core 6 to be inserted therein, the bottom of the containing cavity 121 is provided with two first through holes 122 for exposing the water inlet of the valve core 6 to form the first water inlet 2 and the second water inlet 3, the side wall of the containing cavity 121 is provided with a water outlet passage 123 in communication with the water outlet of the faucet 1, and the mouth of the containing cavity 121 is threadedly connected with a plug element 124 for plugging the valve core 6 in the containing cavity 121, the rotating core of the valve core 6 is exposed outside through the plug element 124 and is connected with the knob 7 for synchronous rotation, and the control switch 8 is fixedly arranged on the fixed connecting seat 12.

[0064] As mentioned above, the fixed connecting seat 12 can fix the valve core 6 through the containing cavity 121 and the plug element 124, and at the same time realize the communication of the first water inlet 2, the second water inlet 3 and the water outlet of the faucet 1. In addition, the control switch 8 is also fixedly arranged on the fixed connecting seat 12, so that the control switch 8 can be fixed near the rotating core of the valve core 6 and the knob 7, which can not only facilitate the triggering of the control switch 8, but also make the structure of the faucet 1 more compact.

[0065] As shown in Figures 2 to 4 , preferably, the first temperature sensor 10 is arranged at the water outlet passage 123, so that the first temperature sensor 10 can accurately detect the water outlet temperature of the faucet 1.

[0066] The control method of the stepless temperature-adjusting water output device comprises the opening and closing control of the electromagnetic valve 5 and the start and stop control of the heating tube 43.

[0067] The opening and closing control of the electromagnetic valve 5 comprises:

[0068] The electromagnetic valve 5 is opened when the opening degree of the second water inlet 3 is greater than or equal to A%, and the electromagnetic valve 5 is closed when the opening degree of the second water inlet 3 is less than A%, wherein A% is the pressure balance opening degree of the second water inlet 3.

[0069] Specifically, the pressure balance opening degree A% of the second water inlet 3 refers to that, in the case that the electromagnetic valve 5 is opened, the opening degree of the second water inlet 3 gradually increases from 0%, and when the opening degree of the second water inlet 3 is equal to A%, the water inlet and outlet pressure of the tank 41 reaches balance, and the water pressure in the tank 41 does not change.

[0070] Preferably, the pressure balance opening degree of the second water inlet 3 is one value in the range of 30% to 80%.

[0071] Preferably, when the tank 41 is provided with a third mechanical temperature controller 45, the start and stop control of the heating tube 43 comprises:

[0072] The set trigger temperature of the third mechanical temperature controller 45 is B, and when the water temperature is lower than the set temperature B, the third mechanical temperature controller 45 controls the heating tube 43 to work at full power, and when the water temperature is higher than or equal to the set temperature B, the third mechanical temperature controller 45 controls the heating tube 43 to stop working.

[0073] Preferably, when the tank 41 is provided with a fourth temperature sensor 48, the start and stop control of the heating tube 43 comprises:

[0074] When the temperature detected by the fourth temperature sensor 48 is lower than the set temperature B, the heating tube 43 is controlled to work at full power, and when the temperature detected by the fourth temperature sensor 48 is higher than or equal to the set temperature B, the heating tube 43 is controlled to work at 10% to 30% of the full power.

[0075] Preferably, the start and stop control of the heating tube 43 further comprises:

[0076] When the temperature of the tank 41 is higher than or equal to the set temperature C, the second mechanical temperature controller 44 controls the heating tube 43 to stop working, and when the heating tube 43 stops working due to the disconnection of the second mechanical temperature controller 44, the second mechanical temperature controller 44 needs to be reset manually so that the heating tube 43 can be started again.

[0077] Preferably, the set temperature B = 90℃.

[0078] Preferably, the set temperature C = 95℃.

[0079] As described above, the control method of the present application only triggers the control switch 8 to control the electromagnetic valve 5 to open when the opening degree of the second water inlet 3 reaches a certain degree. In addition, the third mechanical temperature controller 45 or the fourth temperature sensor 48, in cooperation with the second mechanical temperature controller 44, can complete the control of the water temperature in the tank 41 and the dry burning protection.

[0080] The control scheme of the prior art generally synchronizes the opening and closing of the electromagnetic valve 5 with the opening and closing of the second water inlet 3, that is, as long as the opening degree of the second water inlet 3 is greater than 0%, the electromagnetic valve 5 is also opened synchronously. This will cause the water inlet and outlet pressure of the tank 41 to be unbalanced when the opening degree of the second water inlet 3 is small, and the tank 41 will bear more pressure, thereby affecting the service life and structural safety of the tank 41. In addition, in order to realize the function of dry burning protection, the prior art needs to set a water level sensor in the tank 41, which detects the water level in the tank 41 to ensure that the heating pipe 43 does not start to cause dry burning at low water level. This will cause the product to need to invest more cost to equip the water level sensor, and also need to set the corresponding installation structure and circuit structure for the water level sensor.

[0081] As described above, the control method of the present application can effectively avoid the tank 41 bearing additional pressure by controlling the opening and closing of the electromagnetic valve 5 based on the pressure balance opening degree of the second water inlet 3, thereby increasing the service life and structural reliability of the tank 41, and also reducing the pressure design requirements of the tank 41 to reduce costs. In addition, the control method of the present application can stop the heating pipe 43 from working when there is no water dry burning through the second mechanical temperature controller 44, thereby realizing the function of dry burning protection. This can effectively save the cost of setting a water level sensor, and also reduce the complexity of the product structure.

[0082] Preferably, when the tank 41 is provided with a fourth temperature sensor 48, a low water level detection alarm is further included, the low water level detection alarm comprising:

[0083] When the temperature detected by the fourth temperature sensor 48 decreases by more than 10% within a time range T, a water level alarm of the hot tank 4 is triggered.

[0084] Preferably, the time range T is 2s.

[0085] As described above, when the tank 41 of the present application is provided with a fourth temperature sensor 48, the temperature change reflected by the water level drop can be used to realize the function of water level alarm by using the fourth temperature sensor 48 as a water level sensor.

[0086] Preferably, the knob 7 is fixedly connected with the rotating core of the valve core 6 to rotate synchronously to control the opening of the first water inlet 2 and the second water inlet 3, when the knob 7 rotates in one direction, the opening of the two water inlets will experience the following three stages of changes in turn:

[0087] Stage one: the opening of the water inlet A gradually increases from 0% to 100%, and the opening of the water inlet B maintains at 0%;

[0088] Stage two: the opening of the water inlet A gradually decreases from 100% to 0%, and the opening of the water inlet B gradually increases from 0% to 100% synchronously, during which the sum of the opening of the water inlet A and the water inlet B maintains at 100%;

[0089] Stage three: the opening of the water inlet A maintains at 0%, and the opening of the water inlet B gradually decreases from 100% to 0%;

[0090] If the knob 7 rotates in the opposite direction, the above three stages and the opening change of the water inlets will occur in reverse;

[0091] If the first water inlet 2 is the water inlet A, then the second water inlet 3 is the water inlet B, and vice versa.

[0092] As described above, the present application protects a stepless temperature-adjusting water purification output device and a control method thereof, all technical solutions same or similar to the present application shall be considered to fall within the protection scope of the present application.
