Description

Technical Field

[0001] This disclosure relates to the field of water purification equipment, and in particular to a water purifier and a kitchen appliance including the water purifier. Background Technology

[0002] Current water purifiers generally use heat exchangers to produce warm water, regulating water temperature through heat exchange between hot and cold media. However, this existing solution has significant drawbacks: 1) Long-term water retention in the heat exchanger chamber easily breeds bacteria, leading to substandard effluent hygiene; 2) When the heat exchange area and flow rate are mismatched, the water temperature response is delayed, and the initial stage of room temperature water cannot be avoided; 3) When seasonal temperature differences cause fluctuations in raw water temperature (such as low temperatures in winter / high temperatures in summer), multi-stage heating compensation is required, resulting in poor system temperature control stability and high energy consumption. These problems cause drinking water safety hazards, a decline in user experience, and energy waste, urgently requiring a temperature-controlled water supply solution that can dynamically control temperature, eliminate water retention, and adapt to the environment. Utility Model Content

[0003] The technical problem to be solved by this disclosure is to overcome the shortcomings of existing water purifiers that rely on heat exchangers to mix hot and cold water, which leads to the growth of bacteria in the pipes, and the complex heat exchange structure and sluggish temperature response, making it impossible to achieve instant mixing and dynamic temperature control. The disclosure provides a water purifier and a kitchen device including the water purifier.

[0004] This disclosure solves the above-mentioned technical problems through the following technical solution:

[0005] This disclosure provides a water purifier, which includes a water purification system and a water outlet system;

[0006] The water purification system includes a purified water output pipeline; the water purification system is used to purify the water to be treated in the tap water pipeline to form purified water, and to provide the purified water to the water outlet system through the purified water output pipeline;

[0011] Optionally, the input end of the jet injector includes a first input port;

[0012] The first input port is connected to the purified water input port via a first solenoid valve; the first solenoid valve is used to control the flow rate of purified water flowing into the jet injector.

[0025] This disclosure also provides a kitchen appliance that includes a water purifier as described above.

[0026] The positive advancements of this disclosure are as follows: By replacing the traditional heat exchanger with an ejector, the hot water and purified water in the tank are directly mixed instantly using the Venturi effect, eliminating water stagnation in the pipeline and preventing bacterial growth at the source; the fluid dynamics design of the ejector with dual hot and cold inlets simplifies the system structure and reduces the risk of leakage, while the dynamic balance of the hot and cold ratio is achieved by adjusting the two input pressures or flow rates, improving mixing efficiency and water temperature response speed; in addition, the collaboration between the independent water tank and the ejector provides a basic framework for subsequent expansion of temperature control modules (such as temperature sensing and electric heating compensation), which can further adapt to seasonal temperature differences and ensure stable output of mixed water temperature.

[0139] III. Functions and Effects of Connection Methods

[0140] 1. No water retention design

[0141] Ejector replaces heat exchanger: Mixed water is discharged immediately, preventing bacterial growth.

[0142] The third drain outlet 217 is used for regular drainage: the stagnant water in the hot water tank is circulated and discharged to prevent long-term stagnation (such as automatic drainage when not in use).

[0143] 2. Dynamic temperature control logic

[0144] Flow regulation: The first solenoid valve 203 adjusts the purified water flow rate according to the feedback from the flow meter 110 to maintain the mixing ratio (e.g., increase the flow rate in summer and decrease the flow rate in winter).

[0145] Multi-heating module collaboration:

[0146] Ejector mixes base water temperature → Second heating module 205 undergoes secondary calibration → Hot water tank temperature compensation (monitored by third temperature sensor 215).

[0147] Effect: Adapts to changes in raw water temperature in winter and summer, ensuring a constant mixed water temperature (e.g., raw water 10℃ in winter → mixed water temperature 40℃, raw water 25℃ in summer → mixed water temperature 40℃).

[0148] 3. Hygiene and safety redundancy

[0149] UV sterilization is applied throughout the entire process:

[0150] Sterilization device 111 sterilizes purified water → UV sterilizer performs secondary sterilization on mixed water.

[0151] Effect: The entire process from purification to water output is sterile, avoiding secondary pollution.

[0152] IV. Examples of Specific Use Cases

[0153] Scenario 1: Mixing warm water in winter (target temperature 40℃)

[0154] 1. Environmental conditions: raw water temperature 10℃, hot water tank preset temperature 70℃.

[0155] 2. Operating Procedures:

[0156] When the user turns on the warm water tap, the inlet solenoid valve, diaphragm pump, and UV sterilizer start.

[0157] The jet injector mixes clean water and hot water in a 1:1 ratio, resulting in a mixed water temperature of 40℃ (monitored by the second temperature sensor 206).

[0158] The second heating module 205 is turned off (no need for supplemental heating), and warm water flows out through the warm water solenoid valve.

[0159] 3. Hygiene Guarantee: The sterilization device sterilizes the entire process, and the hot water tank is regularly emptied through the third drain outlet.

[0160] Scenario 2: Mixing warm water in summer (target temperature 40℃)

[0161] 1. Environmental conditions: raw water temperature 25℃, hot water tank preset temperature 50℃.

[0162] 2. Operating Procedures:

[0163] When a user turns on the warm water tap, the system detects that the raw water temperature is high and reduces the hot water heating power.

[0164] The jet injector mixes clean water and hot water in a 3:1 ratio → the mixed water temperature is 41℃ (the second temperature sensor 206 detects that the temperature is too high).

[0165] The second heating module 205 starts to replenish heat by 1°C to 40°C, and then flows out after reaching the target temperature.

[0166] 3. Energy saving effect: Avoids overheating and reduces energy consumption.

[0167] Scenario 3: Device restarts after being idle

[0168] 1. Self-inspection process:

[0169] The third drain outlet 217 opens automatically to drain the water remaining in the hot water tank.

[0170] Sterilization device 111 runs for 30 seconds for UV sterilization and flushing of pipelines.

[0171] 2. Restore normal water supply:

[0172] The water tank is refilled, and the first heating module 209 starts heating to the preset temperature.

[0173] When a user draws water, the system dynamically adjusts the mixing ratio according to the current water temperature.

[0174] Scenario 4: Emergency Drainage Needs

[0175] 1. Operation method:

[0176] Open the ambient temperature water solenoid valve 202 → purified water is discharged directly from the purified water inlet 223.

[0177] Open wastewater switch valve 115 → nanofiltration membrane wastewater is discharged at full speed (if the filter element fails, flush the pipeline).

[0178] 2. Effect: Quickly removes residual water or contaminants from pipes, ensuring hygiene and safety.

[0179] Example 1 systematically solves the problems of water storage hygiene, temperature control lag, and structural complexity of traditional water purifiers by replacing the heat exchanger with jet mixing, multi-stage heating and dynamic adjustment, and full-process UV sterilization. Its core advantages are:

[0180] 1. Hygiene: Eliminates the risk of bacterial growth from the source of the water;

[0181] 2. Efficiency: Real-time matching of hot and cold air flows improves response speed;

[0182] 3. Adaptability: It responds to seasonal temperature differences and changes in user needs through multi-module collaboration.
