[0026] The utility model is described below with reference to the preferred embodiments and the accompanying drawings.

[0027] In the embodiments, the prefix words such as "first" and "second" are used only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of ordinal words and other prefix words to distinguish the description objects in the embodiments does not limit the described objects, and the description of the described objects should be seen in the context of the claims or embodiments, and should not be limited by the use of such prefix words. In addition, in the description of the embodiments, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0028] The utility model embodiment provides a kind of heat and water purifying integrated machine, referring to Figure 1 And Figure 2 The heat and water purifying integrated machine comprises a water inlet channel 11, a filter channel 12, a water storage device 13 and a pressure regulating assembly 14. The water inlet channel 11 and the filter channel 12 are both connected to the water storage device 13, and the water inlet channel 11 is also in communication with the filter channel 12.

[0029] Because the sudden rise or drop of water pressure in the pipeline will affect the normal use of the heat and water purifying integrated machine, and even damage the heat and water purifying integrated machine, for example, excessive water pressure may cause the filter element or other components of the heat and water purifying integrated machine to be damaged due to inability to withstand pressure, thereby affecting the water purification effect and service life of the heat and water purifying integrated machine, therefore the heat and water purifying integrated machine is provided with a pressure regulating assembly 14.

[0030] The pressure regulating assembly 14 divides the water storage device 13 into a first storage area 16 and a second storage area 17, and the water inlet channel 11 and the filter channel 12 are both in communication with the first storage area 16, and the second storage area 17 is away from the water inlet channel 11 and the filter channel 12. The first storage area 16 is used for storing water, and the second storage area 17 is used for storing inert gas.

[0031] The inert gas includes but is not limited to nitrogen, and can be set according to actual conditions, which is not particularly limited here. The pressure regulating assembly 14 includes but is not limited to a membrane, and can be set according to actual conditions, which is not particularly limited here.

[0032] In the embodiment, the water in the water storage device 13 is separated from the inert gas by the pressure regulating assembly 14. When the water pressure rises, the water in the water storage device 13 presses the inert gas, so that the pressure regulating assembly 14 deforms to reduce the pressure of the internal water system of the water purifier. When the water pressure drops, the inert gas presses the water in the water storage device 13 to increase the pressure of the internal water system, so that the pressure in the water purifier is kept within a stable range, realizing automatic pressure regulation, avoiding damage of the components of the water purifier due to excessive pressure, and thus affecting the water purification effect, improving the service life and water purification effect of the water purifier.

[0033] In one embodiment, the pressure regulating assembly 14 includes a membrane. The membrane separates the water storage device 13 into a first storage area 16 and a second storage area 17.

[0034] In the embodiment, the water in the water storage device 13 is separated from the inert gas by the membrane. The membrane has high elasticity and flexibility. When the water pressure rises, the water in the water storage device 13 presses the inert gas, so that the membrane deforms to reduce the pressure of the internal water system of the water purifier. When the water pressure drops, the inert gas presses the water in the water storage device 13 to increase the pressure of the internal water system, so that the pressure in the water purifier is kept within a stable range, realizing automatic pressure regulation, avoiding damage of the components of the water purifier due to excessive pressure, and thus affecting the water purification effect, improving the service life and water purification effect of the water purifier, and having a simple structure, easy to manufacture and maintain.

[0035] In one embodiment, the water storage device 13 is located at the top of the water purifier, i.e., above the water inlet channel 11 and the filter channel 12.

[0036] The position of the water storage device 13 can be set according to actual conditions. The water storage device 13 includes but is not limited to a water storage tank, which is not particularly limited here.

[0037] In the embodiment, the water storage device 13 is located at the top of the water purifier, and the water below the temperature threshold is released by gravity. No water pump needs to be provided in the water storage device 13, which can effectively save energy and reduce costs.

[0038] In one embodiment, the bottom of the water storage device 13 is provided with a water outlet, and the water inlet of the filter channel 12 is located below the water outlet.

[0039] In the embodiment, the water outlet is located at the bottom of the water storage device 13, and the water below the temperature threshold is released from the water outlet by gravity. No water pump needs to be provided in the water storage device, which can effectively save energy and reduce costs.

[0040] In one embodiment, the net heat all-in-one machine further comprises a three-way valve 18 and a controller. The three-way valve 18 comprises a first water inlet end, a second water inlet end and a water outlet end. The first water inlet end is connected with the water inlet channel 11, the second water inlet end is connected with the water storage device 13, the water outlet end is connected with the filter channel 12, and the three-way valve is electrically connected with the controller. The controller is used to adjust the opening degree of the three-way valve, and plays a role of temperature protection for the reverse osmosis membrane.

[0041] Since the hot water generated when the net heat all-in-one machine is heated will flow into the filter channel 12 through the water inlet channel 11, and then flow into the first filter of the net heat all-in-one machine, the reverse osmosis membrane in the first filter is easy to be damaged at high temperature, thereby affecting the water purification effect and service life of the net heat all-in-one machine.

[0042] Referring to Figure 3 , if the water purifier 312 and the water heater 311 are used, the pipelines of the water purifier 312 and the water heater 311 are connected. After the circulation function of the water heater 311 is turned on, the cold water pipeline is heated, and the water heater 311 needs to use cold water to return water in order to form a circulation loop, but when the water returns through the water purifier 312, the water heated by the water heater 311 may transmit heat to the water purifier 312 through heat conduction, and using the water purifier 312 at this time will cause hot water to enter the water purifier 312 through the water inlet channel 11, thereby causing the reverse osmosis membrane in the water purifier 312 to be damaged.

[0043] In this embodiment, the three-way valve 18 is connected with the water inlet channel 11, the water storage device 13 and the filter channel 12, so that the hot water is mixed with the water in the water storage device 13 through the water inlet channel 11, avoiding the hot water flowing directly to the filter channel 12 through the water inlet channel 11, thereby avoiding the hot water directly entering the first filter, ensuring that the water temperature in the first filter is within a safe temperature range, avoiding damage to the reverse osmosis membrane, and improving the service life and water purification effect of the net heat all-in-one machine.

[0044] In one embodiment, a temperature sensor is arranged in the water inlet channel 11, and the net heat all-in-one machine further comprises an alarm, and the temperature sensor is electrically connected with the alarm.

[0045] The temperature sensor sends the obtained water inlet temperature to the alarm, and the alarm will alarm if the water inlet temperature is greater than a temperature threshold. The temperature threshold can be set according to the temperature resistance of the reverse osmosis membrane, and is specifically set according to the actual situation, which is not particularly limited here.

[0046] In this embodiment, the temperature sensor is electrically connected with the alarm, and an alarm is given when the water inlet temperature exceeds the temperature threshold, thereby avoiding damage to the reverse osmosis membrane and improving the service life and water purification effect of the net heat all-in-one machine.

[0047] In one embodiment, the water inlet channel 11 is provided with a temperature sensor and a controller, and the temperature sensor and the controller are electrically connected. The temperature sensor is used to detect the temperature of the water in the water inlet channel 11 and send the temperature of the water to the controller, and the controller adjusts the opening of the three-way valve 18. If the temperature of the water is greater than the temperature threshold, the opening of the three-way valve 18 is adjusted so that the water inlet channel 11, the water storage device 13 and the filtration channel 12 are communicated, and the hot water mixes with the water in the water storage device 13 through the water inlet channel 11, so as to realize water mixing and achieve the purpose of temperature protection of the reverse osmosis membrane.

[0048] In one embodiment, the water purification and heating all-in-one machine further comprises a first filter. The first filter is arranged in the filtration channel 12, and the filter element of the first filter comprises a reverse osmosis membrane.

[0049] The filter element of the first filter can also comprise a post-activated carbon, which can be arranged according to actual conditions and is not particularly limited here.

[0050] The first storage area 16 stores water with a temperature lower than the temperature threshold. In the case where the water inlet channel 11, the water storage device 13 and the filtration channel 12 are communicated, the water in the water inlet channel 11 and the water storage device 13 mixes and then enters the filtration channel 12. The water obtained by mixing the high-temperature water in the water inlet channel 11 and the water in the water storage device 13 enters the filtration channel 12, and the temperature of the water in the filtration channel 12 is within the safe temperature range, so as to avoid damage to the reverse osmosis membrane due to high temperature. It should be noted that the temperature threshold can be obtained according to experimental data, and the value of the temperature threshold is related to many factors, such as the temperature resistance of the filtering material in the first filter, the range of water flow in the water inlet channel 11 and the unit time water output of the filtration channel 12 of the water purification and heating all-in-one machine, etc. The temperature threshold can be arranged according to actual conditions and is not particularly limited here.

[0051] Specifically, an electric three-way valve can be used to communicate the water inlet channel 11, the water storage device 13 and the filtration channel 12 to realize the water mixing function. The arrangement can be made according to actual conditions and is not particularly limited here.

[0052] Considering the temperature resistance of the reverse osmosis membrane, the safe temperature range can be set to below 45℃, and to ensure the service life and water purification effect of the reverse osmosis membrane, the safe temperature range is preferably set to below 35℃. The arrangement can be made according to actual conditions and is not particularly limited here.

[0053] In this embodiment, the water in the water inlet channel 11 and the water storage device 13 flows to the filtration channel 12, so that the hot water mixes with the water in the water storage device 13 through the water inlet channel 11, avoiding the hot water flowing directly to the filtration channel 12 through the water inlet channel 11, and further avoiding the hot water directly entering the filter, so as to ensure that the water temperature in the first filter is within the safe temperature range, avoid damage to the reverse osmosis membrane, and improve the service life and water purification effect of the water purification and heating all-in-one machine.

[0054] In one embodiment, the net heat all-in-one machine further comprises a second filter. The water filtered through the second filter flows into the water storage device 13.

[0055] It can be understood that the second filter is used to preliminarily filter the water in the water inlet channel 11.

[0056] In this embodiment, the water in the water storage device 13 is water filtered through the second filter. Through the filtration of the second filter, the water quality of the water flowing into the water storage device 13 is effectively improved, which helps to improve the safety and health of drinking water and protect human health.

[0057] In one embodiment, the filter element in the second filter comprises PP cotton.

[0058] In this embodiment, the filter element in the second filter comprises PP cotton, which can effectively remove suspended solids in water and play a pretreatment role in water. Before the water enters the first filter, the large-particle impurities in the water are filtered out, protecting the subsequent filter element, prolonging its service life, and improving the water purification effect of the net heat all-in-one machine.

[0059] In one embodiment, the filter element in the second filter further comprises a pre-activated carbon.

[0060] In this embodiment, the filter element of the second filter comprises a pre-activated carbon. The activated carbon has strong adsorption capacity and can effectively remove odors and odor substances in water. The pre-activated carbon can also play a role in protecting the subsequent filter element, reducing the impact of pollutants on the subsequent filter element, prolonging the service life of the subsequent filter element, and reducing maintenance costs.

[0061] In one embodiment, the water storage device 13 is provided with a sterilization device.

[0062] In this embodiment, the water storage device 13 is provided with a sterilization device, which effectively improves the water quality of the water flowing into the water storage device 13, helps to improve the safety and health of drinking water, and protects human health.

[0063] In one embodiment, the water storage device 13 is further provided with a liquid level sensor.

[0064] The water storage level of the water storage device 13 is obtained. When the water storage level is less than the water level threshold, it indicates that the water storage device 13 needs to be replenished. The water inlet channel 11 and the water storage device 13 are connected, so that the water in the water inlet channel 11 can flow into the water storage device 13. The replenishment can avoid the user's usual time and the time when the user is using.

[0065] The water level threshold can be set according to actual conditions, which is not particularly limited here. The water storage level can be obtained by the liquid level sensor, which can be set according to actual conditions, which is not particularly limited here.

[0066] Specifically, the water inlet channel 11 and the water storage device 13 can be connected through an electric one-way valve, which can be set according to actual conditions and is not particularly limited here.

[0067] The electric one-way valve and the liquid level sensor are electrically connected with the controller. According to the water level obtained by the liquid level sensor, the opening of the electric one-way valve is adjusted, so that the water inlet channel 11 and the water storage device 13 are connected, thereby realizing water replenishment of the water storage device 13.

[0068] In this embodiment, the liquid level sensor is used to obtain the water level of the water storage device 13, and the water storage device 13 is replenished through the water inlet channel 11, so as to avoid insufficient water storage of the water storage device 13 and to avoid affecting the normal use of the heat and water integrated machine, thereby improving the user experience.

[0069] In one embodiment, the heat and water integrated machine further comprises a valve and a wastewater storage device 15. The wastewater storage device 15 is connected with the water storage device 13 through the valve.

[0070] After the storage time of the water in the water storage device 13 exceeds the preset time, the water in the water storage device 13 is discharged into the wastewater storage device 15. The wastewater storage device 15 includes but is not limited to a wastewater box, and can be set according to actual conditions. The preset time can be set according to actual conditions and is not particularly limited here.

[0071] Specifically, the valve includes but is not limited to an electric three-way valve or an electric one-way valve. If the electric three-way valve is used, the water outlet end of the electric three-way valve is connected with the wastewater storage device 15, the third water inlet end of the electric three-way valve is connected with the water storage device 13, and the fourth water inlet end of the electric three-way valve can be connected with the filter channel 12, so as to discharge the water in the filter channel 12 into the wastewater storage device 15 when the water quality in the filter channel 12 is poor.

[0072] In this embodiment, after the storage time of the water in the water storage device 13 exceeds the preset time, the water in the water storage device 13 can be discharged into the wastewater storage device 15, thereby ensuring that the water quality meets the standard and helping to improve the safety and health of drinking water and protect human health.

[0073] Figure 4 The flowchart of the control method of the heat and water integrated machine provided in one embodiment of the utility model, the heat and water integrated machine includes a temperature control valve. The temperature control valve can be located at the water inlet of the heat and water integrated machine, that is, the water inlet channel 11 is close to one end of the outside of the heat and water integrated machine, and can be set according to actual conditions and is not particularly limited here.

[0074] The temperature control valve has a plastic interface at one end close to the water inlet channel 11. Since the water inlet channel 11 is used to connect the external water pipe and the heat purification integrated machine, the plastic has poor thermal conductivity, so as to avoid the influence of the temperature rise of the hot water in the external water pipe on the heat purification integrated machine. It should be noted that the material with poor thermal conductivity includes but is not limited to plastic, and the interface of the temperature control valve can also be made of other materials with poor thermal conductivity, which is not particularly limited here. The temperature control valve has a metal interface at one end away from the water inlet channel 11, because the metal has good thermal conductivity, and a temperature sensing element is arranged at the metal interface, so that the temperature sensing element can accurately and timely obtain the change of the water temperature. The material with good thermal conductivity includes but is not limited to metal, and the interface of the temperature control valve can also be made of other materials with good thermal conductivity, which is not particularly limited here.

[0075] The control method of the heat purification integrated machine includes:

[0076] In step S101, the water inlet temperature in the water inlet channel is obtained in response to a pure water acquisition request.

[0077] The heat purification integrated machine has a pure water outlet 19 and a purified water outlet 20. The water filtered by the first filter flows out through the pure water outlet 19, and the water filtered by the second filter flows out through the purified water outlet 20. Both the pure water outlet 19 and the purified water outlet 20 can flow out water. The water flowing out of the pure water outlet 19 is filtered by the first filter, and the water flowing out of the purified water outlet 20 is filtered by the second filter.

[0078] When the pure water acquisition request is received, it indicates that the heat purification integrated machine needs to flow out the pure water filtered by the first filter. Since the reverse osmosis membrane is arranged in the first filter, the water inlet temperature needs to be obtained for subsequent adjustment to avoid damage to the reverse osmosis membrane.

[0079] In step S102, when the water inlet temperature is greater than the temperature threshold, the opening degree of the three-way valve 18 is adjusted to make the water inlet channel 11, the water storage device 13 and the filter channel 12 communicate.

[0080] In this embodiment, whether the water inlet channel 11, the water storage device 13 and the filter channel 12 need to be communicated is determined by judging the water inlet temperature, so that the hot water is mixed with the water in the water storage device 13 through the water inlet channel 11, avoiding the hot water flowing directly to the filter channel 12 through the water inlet channel 11, and further avoiding the hot water directly entering the filter, ensuring that the water temperature in the first filter is within a safe temperature range, avoiding damage to the reverse osmosis membrane, and improving the service life and water purification effect of the heat purification integrated machine.

[0081] In one embodiment, the second water inlet end of the three-way valve 18 is connected with the water supplement channel of the water storage device. The opening degree of the first water inlet end of the three-way valve 18 is positively correlated with the target water flow, the opening degree of the first water inlet end is positively correlated with the first difference, and the opening degree of the first water inlet end is negatively correlated with the second difference.

[0082] wherein the first difference is the difference between the filtered water temperature in the filtering channel 12 and the stored water temperature in the stored water device 13, and the second difference is the difference between the inlet water temperature and the stored water temperature.

[0083] Specifically, according to the thermodynamic formula v3T3c3=v1T1c1+v2T2c2 and v1+v2=v3, the calculation formula of v1 and v2 can be obtained:

[0084] v1=v3*(t3-t2) / (t1-t2)

[0085] wherein v1 represents the water flow of the inlet water channel 11, i.e. the water flow of the first inlet end of the three-way valve 18, T1 represents the inlet water temperature, c1 represents the specific heat of water at T1, v2 represents the water flow of the replenishment water channel, i.e. the water flow of the second inlet end of the three-way valve 18, T2 represents the stored water temperature in the stored water device 13, c2 represents the specific heat of water at T2, v3 represents the water flow of the filtering channel 12, i.e. the target water flow, T3 represents the filtered water temperature in the filtering channel 12, and c3 represents the specific heat of water at T3.

[0086] wherein T1, T2, T3 and v3 are known quantities, T1 and T2 are real-time detected data, and T3 and v3 are determined according to user requirements.

[0087] The opening degree of the first inlet end is directly related to the water flow v1 of the inlet water channel 11, and there is a functional relationship between the opening degree of the first inlet end and the water flow v1 of the inlet water channel 11. The specific functional relationship and the actual valve control mode adopted are related, and the function can be a linear function, a quadratic function, an exponential function and a power function. More ideally, the relationship between the opening degree of the first inlet end and the water flow v1 of the inlet water channel 11 is a linear function.

[0088] In this embodiment, the opening degree of the first inlet end is calculated according to the target water flow, the filtered water temperature in the filtering channel 12, the stored water temperature in the stored water device 13 and the inlet water temperature, the water flow of the inlet water channel 11 is determined, and the water temperature after mixing of the inlet water channel 11 and the replenishment water channel is ensured to be within a safe temperature range, thereby avoiding damage to the reverse osmosis membrane.

[0089] In one embodiment, the opening degree of the second inlet end of the three-way valve 18 is positively correlated with the target water flow, the opening degree of the second inlet end is positively correlated with the third difference, and the opening degree of the second inlet end is negatively correlated with the fourth difference.

[0090] wherein the third difference is the difference between the filtered water temperature in the filtering channel 12 and the inlet water temperature, and the fourth difference is the difference between the stored water temperature in the stored water device 13 and the inlet water temperature.

[0091] Specifically, the water flow of the second water inlet end of the three-way valve 18 is calculated according to the following formula:

[0092] v2 = v3 * (t3-t1) / (t2-t1)

[0093] The opening degree of the second water inlet end is directly related to the water flow v2 of the water supplement channel, and there is a functional relationship between the opening degree of the second water inlet end and the water flow v2 of the water supplement channel. The specific functional relationship is related to the actual valve control mode, and the function can be a linear function, a quadratic function, an exponential function, and a power function. It is more ideal that the relationship between the opening degree of the second water inlet end and the water flow v2 of the water supplement channel is a linear function.

[0094] In this embodiment, the opening degree of the second water inlet end is calculated according to the target water flow, the filtered water temperature in the filtering channel 12, the stored water temperature in the water storage device 13, and the water inlet temperature, the water flow of the water supplement channel is determined, and the water temperature after mixing of the water inlet channel 11 and the water supplement channel is ensured to be within the safe temperature range, thereby avoiding damage to the reverse osmosis membrane.

[0095] In one embodiment, when the water inlet temperature is not greater than the temperature threshold, the control method of the heat purification integrated machine further includes adjusting the opening degree of the three-way valve 18 to make the water supplement channel be cut off, and the water inlet channel 11 and the filtering channel 12 be communicated.

[0096] If the water inlet temperature is not greater than the temperature threshold, it indicates that the temperature of the water in the filtering channel 12 will not exceed the safe temperature range after the water in the water inlet channel 11 directly flows to the filtering channel 12, and thus the water in the water supplement channel does not need to be mixed with the water in the water inlet channel 11, and the water supplement channel is cut off.

[0097] In this embodiment, when the water inlet temperature is not greater than the temperature threshold, the opening degree of the three-way valve 18 is adjusted to make the water supplement channel be cut off. Since the water in the filtering channel 12 will not exceed the safe temperature range, damage to the reverse osmosis membrane will not be caused, the service life of the reverse osmosis membrane is improved, and the water purification effect of the heat purification integrated machine is improved.

[0098] In one embodiment, when the water inlet temperature is greater than the temperature threshold, the control method of the heat purification integrated machine further includes reducing the opening degree of the temperature control valve.

[0099] The implementation mode of the temperature control valve includes but is not limited to the temperature control valve, which can be electronic control or pure mechanical structure. If the temperature control valve is realized by an electronic control mode, the specific implementation mode includes but is not limited to a temperature sensor and an electronic control valve.

[0100] If the temperature control valve is realized by a pure mechanical structure, the specific implementation mode includes but is not limited to a temperature sensing spring, which can be specifically set according to actual conditions and is not particularly limited here.

[0101] If the temperature control valve is realized by electronic control, the temperature control valve will reduce the opening degree when the inlet water temperature is greater than the temperature threshold. If the temperature control valve is realized by a pure connection and release structure, the temperature sensing starting point of the temperature sensing spring is the temperature threshold, that is, after the inlet water temperature reaches the temperature threshold, the elasticity of the temperature sensing spring will change with the inlet water temperature.

[0102] After reducing the opening degree of the temperature control valve, the water quantity in the inlet water channel 11 is reduced, and another part of water required by the net heat all-in-one machine is supplemented by the water in the water storage device 13. The water in the water storage device 13 flows out of the water storage device 13 through the water supplement channel, mixes with the water in the inlet water channel 11, and then flows into the filtering channel 12.

[0103] In this embodiment, when the inlet water temperature is greater than the temperature threshold, the opening degree of the temperature control valve is reduced to reduce the water flow rate of the inlet water channel 11 flowing into the filtering channel 12, to avoid that the hot water directly flows to the filtering channel 12 through the inlet water channel 11, and then to avoid that the hot water directly enters the filter, to ensure that the water temperature in the filter is in a safe temperature range, to avoid damage to the reverse osmosis membrane, and to improve the service life and water purification effect of the net heat all-in-one machine.

[0104] In one embodiment, when the inlet water temperature is greater than the temperature threshold, the control method of the net heat all-in-one machine further includes that the opening degree of the temperature control valve is positively correlated with a third difference value, and the opening degree of the temperature control valve is negatively correlated with a fourth difference value.

[0105] The third difference value is the difference between the filtered water temperature in the filtering channel 12 and the storage water temperature in the water storage device 13, and the fourth difference value is the difference between the inlet water temperature and the storage water temperature.

[0106] Specifically, the opening degree of the temperature control valve is calculated according to the following formula:

[0107] v1=v3*(t3-t2) / (t1-t2)

[0108] The opening degree of the temperature control valve is directly related to the water flow rate v1 of the inlet water channel 11, and there is a functional relationship between the opening degree of the temperature control valve and the water flow rate v1 of the inlet water channel 11. The specific functional relationship is related to the actual valve control mode, and the function can be a linear function, a quadratic function, an exponential function, and a power function. It is more ideal that the relationship between the opening degree of the temperature control valve and the water flow rate v1 of the inlet water channel 11 is a linear function.

[0109] In this embodiment, the opening degree of the temperature control valve is calculated according to the target water flow rate, the filtered water temperature in the filtering channel 12, the storage water temperature in the water storage device 13, and the inlet water temperature, to determine the water flow rate of the inlet water channel 11, to avoid that a large amount of water exceeding the temperature threshold enters when the inlet water temperature is too high, to ensure that the water temperature after mixing of the inlet water channel 11 and the water supplement channel is in a safe temperature range, and to avoid damage to the reverse osmosis membrane.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, but these changes and modifications all fall within the protection scope of the present application.
