Description

Technical Field

[0001] The invention relates to the technical field of drinking water equipment control, and in particular to a hot water output control method of a multifunctional water dispenser. Background Art

[0002] The hot water output technology of water dispensers mainly involves heating elements, temperature control systems and water outlet systems. When existing water dispensers are manufactured, water is heated by heating elements and temperature sensors. However, in general, the boiling temperature of water decreases with changes in altitude, affecting the outlet temperature of hot water. This not only affects the stability of the water dispenser, but also seriously affects the user experience.

[0003] Prior art 1, application number: CN 202410926794.8 discloses a water dispenser and its temperature control method, device and storage medium, the method comprising: obtaining the water outlet time of the water dispenser, and when the water outlet time of the water dispenser reaches the preset time threshold, obtaining the target hot water outlet flow rate and the actual hot water outlet flow rate of the water dispenser; obtaining the control parameters of the hot water pump according to the target hot water outlet flow rate and the actual hot water outlet flow rate; controlling the hot water pump according to the control parameters, so that the water dispenser works in a constant temperature water outlet mode. Although the water outlet flow rate of the hot water pump is continuously corrected by adjusting the control parameters of the hot water pump according to the target hot water outlet flow rate and the actual hot water outlet flow rate to reduce the difference between the target hot water inlet flow rate and the actual hot water inlet flow rate, so that the actual water outlet temperature of the water dispenser is constantly close to the target water temperature, the purpose of precise temperature control is achieved, and the water outlet of the water dispenser is ensured to be constant temperature. However, its control accuracy is low, and there is no adaptive adjustment of the temperature according to different altitudes, resulting in the need for further improvement of the intelligence of the water dispenser.

[0004] Prior art 2, application number: CN 202410274154.3 discloses a wall-mounted water dispenser, which includes a water tank, a heating mechanism, a sterilization mechanism and a diversion mechanism. The water tank is used to store filtered water, the heating mechanism is connected to the water tank, the heating mechanism is used to heat the filtered water, the sterilization mechanism is connected to the water tank and the heating mechanism, the sterilization mechanism is used to sterilize the filtered water, the diversion mechanism is connected to the water tank, the heating mechanism and the sterilization mechanism, and the diversion mechanism is used to divert the filtered water flowing out of the water tank. Although it has the effect of improving the problem that the wall-mounted water dispenser cannot sterilize both normal temperature water and hot water at the same time. However, there is no control and adjustment of the hot water output, which affects the user experience of the water dispenser.

[0005] Prior art three, application number: CN 202410703010.5 discloses a serious water dispenser and its control method, the water dispenser includes: a water purification module, a heat storage module, a heating module, a pumping member and a control module; the water inlet end of the water purification module is used to communicate with the water supply system; the water inlet end of the heat storage module is connected to the water outlet end of the water purification module; the water inlet end of the heating module is connected to the water outlet end of the heat storage module, and the water outlet end of the heating module can be selectively connected to the water outlet of the heat storage module or the water dispenser through the valve control; the pumping member is used to drive the water flow through the heat storage module to the heating module; the control module is respectively connected to the water purification module, the valve control, the heating module and the pumping member. Although it can provide users with a large flow of high-temperature clean water in a customized manner, it meets the user's instant drinking needs for hot water and ensures healthy drinking water. However, the hot water control method is relatively simple, and it does not match the environment, resulting in the need to further improve its temperature regulation accuracy.

[0006] At present, the existing technologies 1, 2 and 3 have the problem that the hot water control method of the water dispenser is relatively simple, the function is relatively simple, and the matching and adaptation with the geographical location of use are not achieved.

[0035] Based on the climate data of the user's geographical location, the changing trend of the ambient temperature in the future period is evaluated in real time, the changing trend is identified, and the initial heating power is adjusted;

[0036] According to the predicted temperature drop in the changing trend, an adjustment value is calculated, and the adjustment value is based on the temperature drop amplitude and rate; the initial heating power is added to the adjustment value to obtain the final initial heating power; according to the predicted temperature rise amplitude, an adjustment value is calculated, and the adjustment value is based on the temperature rise amplitude and rate; the initial heating power is subtracted from the adjustment value to obtain the final initial heating power.
