Description

Technical Field

[0001] The present invention relates to the technical field of water supply devices, and in particular to a heating method for a water supply device and a water supply device. Background Art

[0002] Water supply devices such as water dispensers, water purifiers, and water heaters usually use water tanks to heat the water inside to a set hot water temperature. This set hot water temperature is the water use temperature, and then enters the insulation state. Because the high-temperature water tank has heat exchange with the environment, some heat will be dissipated into the environment, causing the water temperature in the tank to drop. The higher the water temperature in the water tank, the more severe the heat exchange with the environment, and the more severe the heat loss of the water tank. When the water temperature in the water tank drops to a certain value, in order to ensure that the water outlet temperature of the water tank meets the temperature specified by national standards, the heating device in the water tank will restart heating until the hot water temperature reaches the set temperature. In this way, the water tank heating device will be repeatedly heated, and the water tank will repeatedly dissipate heat at high temperature and be reheated, resulting in large heat loss and waste of resources. In winter, when the ambient temperature is low, the heat loss will be even greater.

[0003] Therefore, there is an urgent need to design a heating method and a water supply device for a water supply device to reduce the heat exchange between the water tank and the environment, reduce the heating frequency of the water tank, and reduce energy consumption. Summary of the Invention

[0004] The purpose of the present invention is to provide a heating method for a water supply device and a water supply device, so as to reduce the heat exchange between the water tank and the environment, reduce the heating frequency of the water tank, and reduce energy consumption.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] The present invention provides a heating method for a water supply device, comprising the following steps:

[0007] According to the user's water consumption information, obtain the starting heating temperature of the water tank;

[0008] When the water temperature in the water tank drops to the starting heating temperature, the water is heated to a first preset temperature.

[0009] The water outputted from the water tank is subjected to secondary heating and heated to a water use temperature, wherein the water use temperature is higher than the first preset temperature.

[0010] The heating method of the water supply device obtains the starting heating temperature of the water tank according to the user's water usage information, performs primary heating when the water temperature in the water tank drops to the starting heating temperature, and heats it to the first preset temperature, and performs secondary heating on the water output by the water tank and heats it to the water use temperature, wherein the water use temperature is higher than the first preset temperature, that is, the water tank is heated to the first preset temperature (insulation temperature) in the primary heating and is lower than the water use temperature, which reduces the temperature difference between the water tank and the ambient temperature, reduces the heat exchange between the water tank and the environment, thereby slowing down the temperature drop speed of the water tank, reducing the frequency of insulation heating, and achieving the purpose of reducing the energy consumption of the water tank; and the starting heating temperature can be obtained according to the user's water usage information, so as to timely adjust the heating of the water tank according to different needs to avoid wasting resources.

[0011] As a preferred solution of the heating method for the water supply device, the water use information includes the water use suspension time or water use amount.

[0012] The starting heating temperature of the water tank is obtained according to the water suspension time or water consumption, and the corresponding starting heating temperature can be obtained according to the water demand, thereby reducing the energy consumption of the water tank.

[0013] As a preferred solution of the heating method of the above-mentioned water supply device, the user's water suspension time is detected. If the water suspension time exceeds a first preset time, the water temperature in the water tank drops to a first temperature, and the first-level heating is performed; wherein, the first temperature is the starting heating temperature.

[0014] By detecting the user's water suspension time, when the user does not use water for a long time, that is, the water suspension time exceeds the first preset time, the first-level heating will be performed only when the water temperature in the water tank drops to the first preset time to avoid high-frequency repeated heating of the water tank.

[0015] As a preferred solution of the heating method of the water supply device, the water consumption of the user is detected, and the starting heating temperature is obtained according to the water consumption.

[0016] By detecting the user's water usage, the starting heating temperature is obtained, and the starting heating temperature of the water tank is obtained according to different water usage requirements, avoiding high-frequency repeated heating of the water tank.

[0017] As a preferred solution of the heating method of the water supply device, the water supply device is set with at least two water volume intervals, and different water volume intervals correspond to different starting heating temperatures;

[0018] The water consumption of the user is detected, and the water consumption interval to which the water consumption belongs is determined, so as to obtain the corresponding starting heating temperature according to the water consumption interval to which the water consumption belongs.

[0019] By setting at least two water volume intervals, different water volume intervals correspond to different starting heating temperatures, so that the corresponding starting heating temperature can be obtained according to the different water consumption of users, and the heating control of the water tank can be achieved more accurately to avoid wasting resources.

[0020] As a preferred solution of the heating method of the above-mentioned water supply device, the user's water consumption is detected. If the water consumption falls within a water consumption range less than a first preset water consumption, the starting heating temperature is a second temperature, which is higher than the first temperature. When the water temperature in the water tank drops to the second temperature, the first-level heating is started;

[0021] If the water consumption belongs to a water consumption range greater than the first preset water consumption, the starting heating temperature is a third temperature, and the third temperature is higher than the second temperature. When the water temperature in the water tank drops to the third temperature, the first-level heating is started.

[0022] Two water volume intervals are set. The water volume interval to which the user's water consumption belongs is determined by judging the size of the water volume compared with the first preset water volume, which avoids waste of resources to a certain extent and the judgment procedure is relatively simple.

[0023] As a preferred solution of the heating method of the water supply device, the water temperature is obtained, and the first preset temperature is obtained according to the water temperature.

[0024] The first preset temperature is obtained according to the user's water temperature, so that the corresponding first preset temperature is obtained according to different water temperatures, and the water tank is heated accordingly according to different water temperatures, thereby reducing the waste of resources caused by heating the water in the water tank.

[0025] The present invention also provides a water supply device, which is heated using the above-mentioned heating method for the water supply device. The water supply device includes a water tank, a first-level heating module is provided in the water tank, and a second-level heating module is provided on the water outlet pipe of the water tank.

[0026] The water supply device heats the water in the water tank through the primary heating module and heats it to a first preset temperature, and performs secondary heating on the water output from the water tank through the secondary heating module and heats it to the water use temperature. The water use temperature is higher than the first preset temperature, so that the insulation temperature of the water tank is lower than the water use temperature, thereby reducing the temperature difference between the water tank and the ambient temperature, reducing the heat exchange between the water tank and the environment, and reducing energy consumption.

[0027] As a preferred solution of the above-mentioned water supply device, a pressure boosting device is provided on the water outlet pipe.

[0028] A pressure booster is provided on the water outlet pipe of the water tank to ensure that the water in the water tank can be smoothly discharged through the water outlet pipe.

[0029] As a preferred solution of the above-mentioned water supply device, a heat-insulating layer is provided inside and / or outside the water tank.

[0030] The inside and / or outside of the water tank are provided with a heat-insulating layer, which can achieve a better heat-insulating effect on the water tank, thereby achieving the purpose of reducing energy consumption.

[0031] Beneficial effects of the present invention:

[0032] The heating method of the water supply device proposed in the present invention obtains the starting heating temperature of the water tank according to the user's water usage information, performs primary heating when the water temperature in the water tank drops to the starting heating temperature, and heats it to the first preset temperature, and performs secondary heating on the water output from the water tank and heats it to the water use temperature, wherein the water use temperature is higher than the first preset temperature, that is, the water tank is heated to the first preset temperature (insulation temperature) in the primary heating, which is lower than the water use temperature, reducing the temperature difference between the water tank and the ambient temperature, reducing the heat exchange between the water tank and the environment, thereby slowing down the temperature drop time of the water tank, reducing the frequency of insulation heating, and achieving the purpose of reducing the energy consumption of the water tank; and the starting heating temperature can be obtained according to the user's water usage information, so as to timely adjust the heating of the water tank according to different needs to avoid wasting resources.

[0033] The water supply device proposed in the present invention heats the water in the water tank through a primary heating module and heats it to a first preset temperature, and performs secondary heating on the water output from the water tank through a secondary heating module and heats it to a water use temperature. The water use temperature is higher than the first preset temperature, so that the insulation temperature of the water tank is lower than the water use temperature, thereby reducing the temperature difference between the water tank and the ambient temperature, reducing the heat exchange between the water tank and the environment, and reducing energy consumption.

[0044] Example 1:

[0045] Water supply devices typically use a water tank to heat the water inside to a set hot water temperature. This set hot water temperature is the water use temperature, and then enters a heat preservation state. Because the high-temperature water tank exchanges heat with the environment, some heat will be dissipated into the environment, causing the water temperature in the tank to drop. The higher the water temperature in the water tank, the more severe the heat exchange between the water tank and the environment, and the more severe the heat loss of the water tank. When the water temperature in the water tank drops to a certain value, in order to ensure that the water outlet temperature of the water tank meets the temperature specified by national standards, the heating device in the water tank will restart heating until the hot water temperature reaches the set temperature. This will cause the water tank heating device to heat repeatedly, and the water tank to repeatedly dissipate heat at high temperatures and then reheat, resulting in large heat loss and waste of resources. In winter, when the ambient temperature is low, the heat loss will be even greater.

[0046] To solve the above problems, Figure 1 As shown, this embodiment provides a water supply device, including a water tank 1, the water tank 1 is connected to a water inlet pipe and a water outlet pipe, and a first-level heating module 2 is provided in the water tank 1, and the first-level heating module 2 is used to perform a first-level heating on the water in the water tank 1, and heat it to a first preset temperature (insulation temperature). A second-level heating module 3 is provided on the outlet pipe of the water tank 1, and the second-level heating module 3 is an instant heating module, and the second-level heating module 3 is used to perform a second-level heating on the water output from the outlet pipe, and heat it to the water use temperature. The water use temperature is higher than the first preset temperature, so that the insulation temperature of the water tank 1 is lower than the water use temperature, thereby reducing the temperature difference between the water tank 1 and the ambient temperature, reducing the heat exchange between the water tank 1 and the environment, and reducing energy consumption. In this embodiment, the water supply device can be a water dispenser, a water purifier, a water heater, etc.

[0047] Optionally, a switch valve 5 is provided at the outlet end of the water outlet pipe, and the switch valve 5 is used to control the outlet pipe to open or close the water outlet to control the outflow of water. Preferably, a booster device 4 is provided on the water outlet pipe, and the booster device 4 can be a booster pump. The booster device 4 is provided on the water outlet pipe connecting the secondary heating module 3 and the water tank 1. The booster device 4 ensures that the water in the water tank 1 has sufficient pressure for output.

[0048] To reduce energy consumption of water tank 1, an insulation layer is provided inside and / or outside of water tank 1. The insulation layer is made of a material with good thermal insulation properties. This insulation layer effectively insulates water tank 1, thereby reducing energy consumption. The insulation layer can be provided inside or outside of water tank 1, or both inside and outside of water tank 1 to achieve a better insulation effect. The specific structure of the insulation layer is known in the art and will not be described in detail here.

[0049] Optionally, the water supply device also includes an intelligent control system, which includes a data collection module, a data storage module, an intelligent analysis module and a control module, wherein the data collection module, the data storage module and the intelligent analysis module are electrically connected to the control module respectively, and the water usage information of the water supply device is collected by the data collection module and stored in the data storage module. The user's water usage habits are analyzed by the intelligent analysis module, and the heating of the water supply device can be controlled according to the user's water usage habits.

[0050] Example 2:

[0051] This embodiment provides a heating method for a water supply device, which is applied to the water supply device in the first embodiment, that is, it can be applied to the heating process of a water dispenser, a water purifier, and a water heater. Figure 2 As shown, the following steps are included:

[0052] The starting heating temperature of the water tank 1 is obtained according to the user's water usage information.

[0053] When the water temperature in the water tank 1 drops to the starting heating temperature, the first stage of heating is performed and heated to the first preset temperature.

[0054] The water outputted from the water tank 1 is subjected to secondary heating and is heated to a water use temperature, wherein the water use temperature is higher than a first preset temperature.

[0055] The heating method of the water supply device obtains the starting heating temperature of the water tank 1 according to the user's water usage information, performs primary heating when the water temperature in the water tank 1 drops to the starting heating temperature, and heats it to the first preset temperature, and performs secondary heating on the water output by the water tank 1 and heats it to the water use temperature, wherein the water use temperature is higher than the first preset temperature, that is, the water tank 1 is heated to the first preset temperature (insulation temperature) lower than the water use temperature in the primary heating, thereby reducing the temperature difference between the water tank 1 and the ambient temperature, reducing the heat exchange between the water tank 1 and the environment, thereby slowing down the temperature drop speed of the water tank 1, reducing the frequency of insulation heating, and achieving the purpose of reducing the energy consumption of the water tank 1; and the starting heating temperature can be obtained according to the user's water usage information, so as to timely adjust the heating situation of the water tank 1 according to different needs to avoid wasting resources.

[0056] Example 3:

[0057] like Figure 3 As shown, this embodiment provides a method for heating a water supply device. This embodiment is an improvement made on the basis of the second embodiment. First, it is necessary to detect whether the water supply device is in a working state. If the water supply device is in a non-working state, the following steps are performed:

[0058] S11. Obtain the user's water suspension time.

[0059] S12: Determine whether the water use suspension time exceeds a first preset time.

[0060] S13: If the water use suspension time exceeds the first preset time, the water temperature in the water tank is detected.

[0061] S14: Determine whether the water temperature in the water tank 1 drops to a first temperature.

[0062] The starting heating temperature of the water tank 1 is obtained according to the water suspension time, and the corresponding starting heating temperature can be obtained according to the water demand, thereby reducing the energy consumption of the water tank 1. At this time, the first temperature is the starting heating temperature.

[0063] S15: If yes, perform primary heating and heat to the first preset temperature.

[0064] The first preset temperature can be determined according to the water temperature, so that the corresponding first preset temperature can be obtained according to different water temperatures, so as to heat the water in the water tank 1 accordingly according to different water temperatures, thereby reducing the waste of resources caused by heating the water in the water tank 1.

[0065] Specifically, when the water temperature is low, a lower first preset temperature can be set; when the water temperature is high, the first preset temperature can be appropriately increased. The relationship between the first preset temperature and the water temperature can be linear or nonlinear. For example, the first preset temperature is 80% of the water temperature.

[0066] When the water in the water tank 1 is heated to the first preset temperature, it starts to be kept warm. If the water use is suspended for more than the first preset time and the water temperature in the water tank 1 drops to the first temperature, the water tank 1 is reheated to maintain the water in the water tank 1 within a certain temperature range, thereby avoiding high-frequency repeated heating of the water tank 1.

[0067] S16: Perform secondary heating on the water output from the water tank 1 and heat it to the water use temperature.

[0068] When water is used, the water transported in the water outlet pipe of the water tank 1 is heated to the water temperature by the secondary heating module 3 so as to meet the user's needs.

[0069] The intelligent control system intelligently monitors the water usage of on-site devices, collects and uploads data, and stores and analyzes this data. This allows different heating logics to be used for different devices during extended periods of nighttime water inactivity, with heating starting at different times. The devices remain dormant at other times of the night. This ensures water availability for users while also minimizing ineffective heating by employing different heating logics for different device usage scenarios, ultimately achieving energy savings.

[0070] Example 4:

[0071] like Figure 4 As shown, this embodiment provides a method for heating a water supply device. This embodiment is an improvement made on the basis of the second embodiment. First, it should be detected whether the water supply device is in a working state. If the water supply device is in a working state, the following steps are performed:

[0072] S21. Obtain the user's water consumption.

[0073] The starting heating temperature of the water tank 1 is obtained according to the water consumption of the user, and the corresponding starting heating temperature can be obtained according to the water demand, thereby reducing the energy consumption of the water tank 1.

[0074] S22: Determine whether the water consumption is less than a first preset water consumption.

[0075] S231. If the water consumption is less than the first preset water consumption, the starting heating temperature is the second temperature, which is higher than the first temperature. When the water in the water tank 1 drops to the second temperature, the first-level heating is started.

[0076] The user's water consumption is detected, and the water consumption interval to which the water consumption belongs is determined, so as to obtain the corresponding starting heating temperature according to the water consumption interval to which the water consumption belongs.

[0077] S232: If the water consumption belongs to a water consumption range not less than the first preset water consumption, the starting heating temperature is the third temperature, which is higher than the second temperature. When the water in the water tank 1 drops to the third temperature, the first-level heating is started.

[0078] The water supply device is configured with at least two water volume intervals, each corresponding to a different starting heating temperature. The starting heating temperature is determined by detecting the user's water usage, thereby determining the starting heating temperature of the water tank 1 based on different water usage requirements, thereby avoiding frequent repeated heating of the water tank 1.

[0079] In this embodiment, two water volume intervals are provided. By comparing the difference between the water volume and the first preset water volume, the water volume interval to which the user's water consumption belongs is determined. This avoids waste of resources to a certain extent, and the determination process is relatively simple. Of course, the water volume intervals are not limited to two, and can be divided into three, four, or more. Different water volume intervals correspond to different starting heating temperatures, so that the corresponding starting heating temperature is obtained according to the different water consumption of the user, and the heating control of the water tank 1 is more accurately achieved, avoiding waste of resources.

[0080] S24: Perform secondary heating on the water output from the water tank 1 and heat it to the water use temperature.

[0081] When water is used, the water transported in the water outlet pipe of the water tank 1 is heated to the water temperature through the secondary heating module to meet the user's needs.

[0082] The intelligent control system intelligently monitors the water usage of on-site devices, collects and uploads data, and stores and analyzes this data. This allows different heating logics to be used for different devices during extended periods of nighttime water inactivity, with heating starting at different times. The devices remain dormant at other times of the night. This ensures water availability for users while also minimizing ineffective heating by employing different heating logics for different device usage scenarios, ultimately achieving energy savings.

[0083] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
