Description

Technical Field

[0001] This invention belongs to the technical field of countertop water purifiers, specifically relating to countertop water purifiers and their control methods. Background Technology

[0002] Water purifiers, as water treatment devices that can deeply filter and purify water according to user requirements, are gaining increasing recognition and favor among consumers. Currently, countertop water purifiers on the market allow users to simultaneously obtain both room temperature purified water and hot water by directly connecting to the tap and filtering and heating the raw water, gradually replacing older models with only water purification functions. However, existing countertop water purifiers must be placed in locations with taps, preventing flexible placement based on user space needs, leading to inconvenience. Furthermore, current countertop water purifiers only offer room temperature and hot water functions, lacking ice water and ice-making capabilities, thus failing to meet diverse user needs. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a countertop water purifier and its control method that completely eliminates the dependence on the installation location of the faucet, allows the water purifier to be flexibly placed in any location for use, and has ice-making and ice water functions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The countertop water purifier includes a main body, a human-computer interaction module, a water heating device, an ice water production mechanism, an ice making and de-icing module, and an ice dispensing mechanism.

[0006] The machine body is equipped with a clean water tank and a raw water tank, a water purification system and a control module. The water purification system is used to purify the raw water in the raw water tank and then deliver it to the clean water tank. The machine body has a water outlet on the front side.

[0007] The human-computer interaction module is located on the front of the machine and is operated by the user to release heated water, ice water or room temperature water of the selected temperature and volume from the water outlet. Alternatively, the user can operate the ice outlet of the machine to release ice blocks, including cotton-feel ice or transparent ice.

[0008] The water heating device includes a heater and a hot water pump connected to a clean water tank and the heater respectively. The control module controls the working flow rate of the hot water pump and the working power of the heater to discharge hot water at the required temperature from the outlet.

[0009] The ice water production mechanism includes an inlet pump, a chilled water pump, an ice water tank, a water level controller, and a chiller for cooling the liquid in the ice water tank. The water level controller is used to control the water level in the ice water tank at a preset height. The inlet pump is connected to both the clean water tank and the ice water tank to replenish the ice water tank with pure water. The chilled water pump is connected to both the ice water tank and the outlet to discharge ice water through the outlet.

[0010] The ice-making and de-icing module includes an ice-making evaporator, a compressor, a condenser, a circulation pump, and an ice-making box located on top of the ice water tank. The ice-making evaporator is located on the top of the ice-making box, and several downward-extending ice-making columns are provided at the bottom of the ice-making evaporator. The ice-making columns extend into the liquid surface of the ice-making box. The ice-making evaporator, compressor, and condenser form a refrigeration circulation pipeline through capillary copper tubes. A water spray nozzle is provided at the top of the ice water tank. The circulation pump is connected to the water spray nozzle and the ice water in the ice water tank through pipes to selectively generate water flow into the ice-making box, so that the ice-making columns produce cotton-feel ice with bubbles or completely transparent ice. A de-icing pipeline is also connected in parallel on the capillary copper tube between the compressor and the ice-making evaporator in the refrigeration circulation pipeline. A de-icing solenoid valve is provided on the de-icing pipeline. The de-icing solenoid valve is used to allow the refrigerant in the compressor to enter the ice-making evaporator through the de-icing pipeline to release heat, thereby melting the ice at the point of contact with the ice-making columns and detaching it.

[0011] The ice dispensing mechanism includes a dispensing driver, a screw rod, and an ice basket. The ice basket is located inside the ice water tank below the ice-making box and is used to receive ice cubes produced by the ice-making box. A feeding chamber with its bottom inclined upward is provided on one side of the inner cavity of the ice basket. The upper end of the feeding chamber forms an ice outlet located on the front side of the machine body. The screw rod is correspondingly inclined and arranged in the feeding chamber and at the bottom. The dispensing driver is used to drive the screw rod to rotate relative to each other, so that the ice cubes in the ice basket are discharged through the ice outlet along the spiral guidance of the screw rod.

[0012] Compared with existing technologies, the countertop water purifier of this invention integrates a raw water tank, a purified water tank, a water purification system, and an independent ice water production mechanism, ice making and de-icing modules. This enables self-sufficiency in water supply without the need for an external faucet and meets the demand for drinking water at various temperatures. The countertop water purifier can be flexibly placed in any location within the user's space according to their needs. Its ice making and de-icing modules utilize circulating water flow and parallel de-icing pipelines to produce cotton-feel ice containing bubbles or completely transparent ice on the same ice-making column as needed. The de-icing solenoid valve controls heat release to achieve rapid and gentle ice removal. Combined with the spiral rod ejection mechanism in the inclined push chamber, it achieves a fully automatic and efficient process from ice selection and ice making to ice dispensing. At the same time, through the coordinated control of the hot water pump and the heating furnace, it accurately outputs hot water at the required temperature and volume. Thus, it integrates the functions of producing room temperature purified water, hot water at various temperatures, ice water, and multiple types of ice cubes in a single countertop unit, significantly improving the convenience of use, space adaptability, and multi-functional satisfaction.

[0013] Furthermore, the ice-making and de-icing module also includes an ice-receiving box located at the bottom of the ice-making box. The feeding chamber is located below one side of the ice-making box. The two sides of the ice-making box are rotatably connected to the upper part of the ice water tank via rotating shafts. The ice-making box is equipped with an ice-pushing drive motor that drives its relative rotation. An ice-pushing plate is rotatably connected to the side of the ice-making box near the feeding chamber. The ice-pushing plate is equipped with a first torsion spring that keeps it parallel or slightly inclined downwards, so that after the ice-pushing drive motor drives the ice-making box to rotate in the forward direction and pours the ice into the ice-receiving box, the ice-pushing drive motor then drives the ice-receiving box in the reverse direction. The ice-making box rotates, causing the ice pusher to push the ice blocks out of the ice-receiving box and drop them into the ice basket. With this configuration, by setting up a rotatable ice-making box and an ice pusher with a torsion spring, the ice-pushing drive motor drives the ice making, pouring, and pushing of ice in a continuous and automatic manner: when the ice-making box rotates forward, it can smoothly pour the ice blocks into the ice-receiving box below; when it rotates in reverse, the ice pusher immediately pushes the ice blocks in the ice-receiving box into the ice basket. This not only avoids jamming or accumulation of ice blocks during the transfer process, but also simplifies the transmission path of ice blocks from production to collection, and improves the smoothness and reliability of ice dispensing.

[0014] Furthermore, the ice-making and de-icing module also includes a first micro switch and a second micro switch arranged at a certain angle on the outside of the ice water tank. A trigger is configured on the rotating shaft on one side of the ice-making box. When the ice-pushing drive motor drives the ice-making box to rotate in the forward direction until the ice cubes inside are poured into the ice-receiving box, the trigger activates the first micro switch, thereby sending a signal to the ice-pushing drive motor to drive the ice-making box to rotate in the reverse direction, causing the ice-pushing plate to push the ice cubes out of the ice-receiving box and trigger the second micro switch. The second micro switch then sends a signal to the ice-pushing drive motor to stop operating. By configuring the ice maker with a trigger and two microswitches arranged at an angle, the key positions of the ice maker's forward and reverse rotation can be precisely detected and controlled: when the trigger activates the first microswitch, it indicates that ice has been poured into the ice receiving box, and the system immediately drives the ice maker to rotate in the reverse direction to push the ice; when the second microswitch is triggered, it indicates that the ice pushing action is completed, and the system stops driving, thus realizing the automatic switching and precise stopping of the two processes of pouring and pushing ice, avoiding motor over-rotation or incomplete action, and improving the automation level and operational reliability of the ice making and discharging cycle.

[0015] Furthermore, the outer end of the ice pusher is provided with at least one guide wheel for engaging with the bottom wall of the ice receiving box. By providing at least one guide wheel at the outer end of the ice pusher, when it contacts and slides with the bottom wall of the ice receiving box, the sliding friction can be converted into rolling friction. This not only effectively reduces the frictional resistance and wear during the movement of the ice pusher, but also ensures that the ice pusher moves smoothly and is not prone to jamming when pushing ice blocks, thereby improving the smoothness of the ice pushing action and the service life of the mechanism.

[0016] Furthermore, the ice basket is equipped with a drain hole connected to the ice water tank, and also includes an ice outlet baffle that is rotatably connected to the upper end of the ice outlet. The ice outlet baffle is used to keep the ice outlet closed after ice is dispensed. With this configuration, the residual water attached to the ice can flow back to the ice water tank by providing a drain hole in the ice basket, reducing ice sticking and waste. At the same time, by providing an ice outlet baffle that can rotatably close the ice outlet, heat exchange between the ice basket and the outside environment is effectively isolated when ice is not being dispensed. This prevents the ice from melting or the refrigeration efficiency from being reduced due to cold air leakage and external heat intrusion, and also avoids the entry of external contaminants. Thus, while improving the preservation quality and hygiene safety of the ice, the energy-saving effect of the equipment is enhanced.

[0017] Furthermore, the purified water tank and the raw water tank are detachably installed on the side of the machine body. The water purification system includes a pre-filter module, an RO filter module, a post-filter module, and a booster pump. The booster pump is used to make the raw water in the raw water tank flow sequentially through the pre-filter module, the RO filter module, and the post-filter module to form purified water entering the purified water tank. By designing the purified water tank and the raw water tank to be detachably installed on the side of the machine body, it is not only convenient for users to clean, maintain, or replace them independently, improving the convenience and hygiene of equipment maintenance, but also allows the purified water tank after deep purification to be directly removed as an independent water container, which is convenient for users to use in kitchen cooking scenarios such as making soup and cooking rice, greatly expanding the multi-functionality of the equipment for home use. At the same time, its water purification system adopts a multi-stage filtration module including a pre-filter, an RO filter, and a post-filter, driven by a booster pump, to ensure the high purity and excellent taste of the produced purified water, ensuring the healthy quality of drinking and cooking water from the source.

[0018] Furthermore, the raw water tank is equipped with a raw water chamber and a wastewater chamber arranged separately, and the raw water chamber and wastewater chamber are interconnected at the top. The water purification system also includes a wastewater valve, which is used to transport the wastewater generated by the RO filter module to the wastewater chamber. With this configuration, by setting up interconnected raw water chambers and wastewater chambers in the raw water tank, and using the wastewater valve to directly recover the wastewater generated by the RO filter module to the wastewater chamber, centralized storage and isolation of wastewater are achieved inside the raw water tank, avoiding the space occupation of additional independent wastewater tanks, making the overall structure more compact. At the same time, the top-connected design allows the raw water chamber to be supplemented from the wastewater chamber when the water volume is insufficient, optimizing the raw water utilization efficiency, reducing the frequency of water addition, and improving user convenience and the integration level of the equipment.

[0019] A control method for a countertop water purifier, comprising the countertop water purifier, wherein the human-machine interaction module includes a human-machine interaction interface, and the human-machine interaction interface is provided with a temperature selection area, a water output selection area, a water dispensing button, and an ice dispensing button.

[0020] The temperature selection area includes ice water button, room temperature button, warm water button, hot water button, and boiling water button.

[0021] The water dispensing selection area includes buttons for small cup, medium cup, large cup, and continuous dispensing.

[0022] After selecting the desired drinking water temperature in the temperature selection area and the desired drinking water volume in the water dispensing volume selection area, you can obtain drinking water of the corresponding temperature and volume by pressing the water dispensing button.

[0023] You can obtain a set number of ice cubes by pressing the ice dispensing button.

[0024] The countertop water purifier control method of the present invention clearly divides the temperature selection area and the water volume selection area on the integrated human-computer interaction interface, allowing users to obtain drinking water with precise temperature and volume with a simple button combination, such as first selecting the temperature and cup volume, and then pressing the water dispensing button. Alternatively, the ice dispensing function can be operated independently with a single button. This greatly simplifies the operation process from selection to execution, reduces the user's learning cost, and realizes one-button quick access to room temperature, ice water, multiple levels of hot water, and a fixed amount of ice cubes, improving the intuitiveness of human-computer interaction and the convenience of using the whole machine.

[0025] Furthermore, the human-computer interaction module is configured with at least one custom module. This custom module includes a custom button on the human-computer interaction interface. When the custom button is selected, the human-computer interaction interface displays a custom temperature selection area with an adjustment precision of 1°C. After the user selects a custom water temperature value in the custom temperature selection area and a custom water volume in the water volume selection area, the custom water temperature value and the custom water volume are saved in the custom module. This allows the user to obtain drinking water with the corresponding temperature and volume saved in the custom module by subsequently touching the custom button and the water dispensing button. By setting at least one custom module supporting 1°C precision adjustment in the human-computer interaction interface, users can accurately set and store their own unique combination of water temperature and volume according to their preferences. Afterwards, simply triggering the corresponding custom button and the water dispensing button will reproduce this personalized setting with one click, eliminating the tedious process of repeatedly performing multiple adjustments each time. This achieves highly personalized drinking water customization and significantly improves the operational efficiency and convenience for high-frequency or fixed drinking water needs.

[0026] Furthermore, the ice basket is equipped with an ice block height detector for detecting the stacking height of ice blocks. The human-machine interface also includes a quick refrigeration setting button. Clicking the quick refrigeration setting button allows the human-machine interface to enter the quick setting interface for ice water and ice blocks. The quick setting interface for ice water and ice blocks includes an ice water switch button, an ice block switch button, an ice-making mode selection area, and an ice-making progress display bar. The ice-making mode selection area includes a cotton-feel ice button and a transparent ice button. The ice-making progress display bar displays the detection information fed back by the ice block height detector. With this setup, by setting an ice block height detector in the ice basket and combining it with the dedicated quick refrigeration setting interface on the human-machine interface, users can directly access and intuitively control the ice water and ice block functions with one click: the ice water switch and ice block switch buttons are managed independently, and users can quickly switch between cotton-feel ice and transparent ice modes. At the same time, the ice-making progress display bar reflects the stacking height of ice blocks in real time, realizing centralized monitoring and convenient management of ice water supply and ice block production. This not only meets users' personalized choices for ice feel types but also improves the visualization of ice storage and the controllability of the ice-making process, optimizing the user experience.

[0027] Furthermore, the human-machine interface also includes a device settings button. Clicking the device settings button allows the human-machine interface to enter the device settings interface. The device settings interface includes a settings selection area on one side and an operation display area on the other side corresponding to the settings selection area. The settings selection area includes at least an energy-saving settings button. When the energy-saving settings button is selected, the operation display area enters the energy-saving settings operation display area. The energy-saving settings operation display area includes an ice cube timer switch button and an ice water timer switch button. By sequentially touching the ice cube timer switch button or the ice water timer switch button, the ice cube timer function or the ice water timer function can be turned on or off. When the ice cube timer function or the ice water timer function is on... In this state, the energy-saving setting operation display area shows the ice cube start / stop time operation area or the ice water start / stop time operation area that can be operated by the user. Through this setting, by setting a clear hierarchy of equipment setting menus in the human-machine interface, and including a dedicated energy-saving setting option, users can independently start the timer function of ice cubes or ice water, and customize specific start / stop time periods. This allows users to accurately plan the operation period of the refrigeration equipment, such as pausing ice making at night. This not only effectively avoids energy waste during periods of no use or low demand, but also significantly reduces the noise generated during ice making at night, creating a quiet resting environment. Thus, while improving the intelligent management and operational efficiency of the equipment, it also optimizes the user's living comfort. Attached Figure Description

Detailed Implementation

[0046] The specific embodiments of the present invention are described below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the present invention.

[0047] Example 1:

[0048] See Figures 1 to 17 The tabletop water purifier of the present invention includes a body 1, a human-computer interaction module 2, a water heating device 3, an ice water making mechanism 4, an ice making and de-icing module 5, and an ice block ejection mechanism 6.

[0049] The main body 1 is equipped with a clean water tank 11 and a raw water tank 12, a water purification system and a control module (not shown). The water purification system is used to purify the raw water in the raw water tank 12 and then deliver it to the clean water tank 11. The front of the main body 1 is provided with a water outlet 13 and an ice outlet 64.

[0050] The human-computer interaction module 2 is located on the front side of the body 1. It is operated by the user to release heated water of the selected temperature and volume, ice water or room temperature water from the water outlet, or to release ice from the ice outlet 64 of the body. The ice includes cotton-feel ice or transparent ice.

[0051] The water heating device 3 includes a heating furnace 31 and a hot water pump 32 connected to the clean water tank 11 and the heating furnace 31 respectively. The control module controls the working flow rate of the hot water pump 32 and the working power of the heating furnace 31 to discharge hot water at the required temperature from the outlet 13.

[0052] The ice water production mechanism 4 includes an inlet pump 41, a cold water pump 42, an ice water tank 43, a water level controller 44, and a chiller 45 for cooling the liquid in the ice water tank 43. The water level controller 44 controls the water level in the ice water tank 43 at a preset height. The inlet pump 41 is connected to both the purified water tank 11 and the ice water tank 43 to replenish the ice water tank 43 with purified water. The cold water pump 42 is connected to both the ice water tank and the outlet 13 and is controlled to discharge ice water to the outlet 13. The ice water is preferably drinking water cooled to 5°C.

[0053] The ice-making and de-icing module 5 includes an ice-making evaporator 51, a compressor 52, a condenser 53, a circulation pump 54, and an ice-making box 55 located on top of the ice water tank 43. The ice-making evaporator 51 is located on the upper side of the ice-making box 55, and several downward-extending ice-making columns 511 are provided at the bottom of the ice-making evaporator 51. The ice-making columns 511 extend into the liquid surface of the ice-making box 55. The ice-making evaporator 51, compressor 52, and condenser 53 form a refrigeration circulation pipeline through capillary copper tubes. A water spray nozzle 551 is provided on the upper part of the ice water tank 43. The circulation pump 54 is connected to the water spray nozzle 551 and the ice water tank 43 through pipes. The ice-water connection within 3 is used to selectively generate an ice-water flow into the ice-making container 55, causing the ice-making column 511 to produce cotton-like ice with air bubbles or completely transparent ice. Furthermore, when the ice-water flow passes over the ice-making column 511, the water flow can carry away air bubbles on the ice-making column 511 or those newly formed on the ice, or affect the residence of air bubbles on the ice-making column 511 or on the surface of the ice. This minimizes the influence of air bubbles during the entire ice-forming process, resulting in ice with a crystal-clear appearance, thus creating a... Figure 10 The transparent ice shown, produced by the ice-making process of the ice-making column 511 without the intervention of ice water flow, results in ice blocks with a large number of air bubbles inside, thus forming... Figure 11 The cotton-like ice shown has a de-icing pipeline (not shown) connected in parallel on the capillary copper tube between the compressor 52 and the ice-making evaporator 51 in the refrigeration cycle pipeline. The de-icing pipeline is equipped with a de-icing solenoid valve (not shown). The de-icing solenoid valve is used to allow the refrigerant in the compressor 52 to enter the ice-making evaporator 51 through the de-icing pipeline to release heat, thereby melting the ice at the point of contact with the ice-making column 511 and detaching it.

[0054] The spray nozzle 551 is also used to replenish the ice container 55 with drinking water for use in making ice.

[0055] The ice ejection mechanism 6 includes an ejection driver 61, a spiral rod (not shown), and an ice basket 62. The ejection driver 61 is preferably a motor. The ice basket 62 is located inside the ice water tank 43 below the ice-making box 55 and is used to receive ice cubes made by the ice-making box 55. A pushing chamber 63 with its bottom inclined upward is provided on one side of the inner cavity of the ice basket 62. The upper end of the pushing chamber 63 forms an ice outlet 64 located on the front side of the machine body 1. The spiral rod is correspondingly inclined and arranged inside the pushing chamber 63 and at the bottom. The ejection driver 61 is used to drive the spiral rod to rotate relative to each other so that the ice cubes in the ice basket 62 are discharged through the ice outlet 64 along the spiral guide of the spiral rod.

[0056] The cooler 45 can be a semiconductor cooler 45 or an evaporator connected to the refrigeration cycle pipeline.

[0057] Compared with existing technologies, the countertop water purifier of the present invention integrates a raw water tank 12, a purified water tank 11, a water purification system, and an independent ice water manufacturing mechanism 4, ice making and de-icing module 5. This enables the self-sufficiency of water supply without the need for an external faucet and meets the demand for drinking water at various temperatures. The countertop water purifier can be flexibly placed in any location within the space according to the user's space requirements. Its ice making and de-icing module 5 utilizes circulating water flow and parallel de-icing pipelines to produce cotton-feel ice containing bubbles or completely transparent ice on the same ice making column 511 as needed. The de-icing solenoid valve controls the heat release to achieve rapid and gentle ice removal. Combined with the spiral rod ejection mechanism in the inclined push chamber 63, it realizes a fully automatic and efficient process from ice selection, ice making to ice dispensing. At the same time, through the coordinated control of the hot water pump 32 and the heating furnace 31, it accurately outputs hot water of the required temperature and volume. Thus, it integrates the functions of room temperature purified water, hot water at various temperatures, ice water, and multiple types of ice making within a single countertop unit 1, significantly improving the convenience of use, space adaptability, and multi-functional satisfaction.

[0058] See Figures 1 to 5In one embodiment, the ice-making and de-icing module 5 further includes an ice-receiving box 56 located at the bottom of the ice-making box 55. The feeding chamber 63 is located below one side of the ice-making box 55. The ice-making box 55 is rotatably connected to the upper part of the ice water tank 43 via rotating shafts on both sides. The ice-making box 55 is equipped with an ice-pushing drive motor 57 that drives its relative rotation. An ice-pushing plate 58 is rotatably connected to the side of the ice-making box 55 near the feeding chamber 63. The ice-pushing plate 58 is equipped with a first torsion spring (not shown) that keeps it parallel or slightly inclined downwards, so that after the ice-pushing drive motor 57 drives the ice-making box 55 to rotate in the forward direction and pours the ice inside into the ice-receiving box 56, the ice-pushing drive motor... The machine 57 drives the ice-making box 55 to rotate in the reverse direction, causing the ice pusher 58 to push the ice blocks in the ice receiving box 56 out of the ice receiving box 56 and drop them into the ice basket 62. With this configuration, by setting up a rotatable ice-making box 55 and an ice pusher 58 with a torsion spring, the ice pushing drive motor 57 drives the ice making, pouring and pushing of ice in a continuous automatic action: when the ice-making box 55 rotates in the forward direction, it can smoothly pour the ice blocks into the ice receiving box 56 below. When it rotates in the reverse direction, the ice pusher 58 pushes the ice blocks in the ice receiving box 56 into the ice basket 62. This not only avoids the ice blocks getting stuck or piling up during the transfer process, but also simplifies the transmission path of the ice blocks from making to collecting, and improves the smoothness and reliability of ice dispensing.

[0059] See Figures 1 to 5 In one embodiment, the ice-making and de-icing module 5 further includes a first micro switch 591 and a second micro switch 592 arranged at a certain angle outside the ice water tank 43. A trigger element 593 is configured on the rotating shaft on one side of the ice-making box 55. After the ice-pushing drive motor 57 drives the ice-making box 55 to rotate in the forward direction until the ice inside is poured into the ice-receiving box 56, the trigger element 593 triggers the first micro switch 591, thereby feeding back a signal to the ice-pushing drive motor 57 to drive the ice-making box 55 to rotate in the reverse direction, causing the ice-pushing plate 58 to push the ice in the ice-receiving box 56 out of the ice-receiving box 56 and trigger the second micro switch 592. Then, the second micro switch 592 feeds back a signal to the ice-pushing plate 592. The drive motor 57 stops working. With this setting, by setting a trigger 593 and a first micro switch 591 and a second micro switch 592 arranged at an angle, the key positions of the ice-making box 55 in forward and reverse rotation can be accurately detected and controlled: when the trigger 593 triggers the first micro switch 591, it indicates that the ice has been poured into the ice receiving box 56, and the system then drives the ice-making box 55 to rotate in the reverse direction to push the ice; when the second micro switch 592 is triggered, it indicates that the ice pushing action is completed, and the system stops driving, thereby realizing the automatic switching and precise stopping of the two processes of pouring and pushing ice, avoiding over-rotation of the motor or incomplete action, and improving the automation level and operational reliability of the ice-making and ice-discharging cycle.

[0060] See Figures 1 to 5In one embodiment, the outer end of the ice-pushing plate 58 is provided with at least one guide wheel 581 for cooperating with the bottom wall of the inner cavity of the ice-receiving box 56. By setting at least one guide wheel 581 at the outer end of the ice-pushing plate 58, when it contacts and slides with the bottom wall of the inner cavity of the ice-receiving box 56, the sliding friction can be converted into rolling friction. This not only effectively reduces the frictional resistance and wear of the ice-pushing plate 58 during its movement, but also ensures that the ice-pushing plate 58 moves smoothly and is not prone to jamming when pushing ice blocks, thereby improving the smoothness of the ice-pushing action and the service life of the mechanism.

[0061] See Figures 1 to 5 In one embodiment, the ice basket 62 is provided with a drain hole 622 communicating with the ice water tank 43, and also includes an ice outlet baffle 66 rotatably connected to the upper end of the ice outlet 64. The ice outlet baffle 66 is used to keep the ice outlet 64 closed after ice is discharged. With this configuration, the residual water attached to the ice can flow back to the ice water tank 43 by providing a drain hole 622 in the ice basket 62, reducing the sticking and waste of ice. At the same time, by providing an ice outlet baffle 66 that can rotatably close the ice outlet 64, the heat exchange between the ice basket 62 and the outside is effectively isolated when ice is not being discharged. This prevents the ice from melting or the refrigeration efficiency from being reduced due to cold air leakage and external heat intrusion, and also avoids the entry of external pollutants. Thus, while improving the preservation quality and hygiene safety of ice, the energy-saving effect of the equipment is enhanced.

[0062] See Figures 1 to 8 In one embodiment, the purified water tank 11 and the raw water tank 12 are detachably installed on the side of the body 1. The water purification system includes a pre-filter module, an RO filter module 72, a post-filter module, and a booster pump 73. Preferably, the pre-filter module and the post-filter module are integrated into a composite filter structure 71. The booster pump 73 is used to make the raw water in the raw water tank 12 flow sequentially through the pre-filter module, the RO filter module 72, and the post-filter module to form purified water entering the purified water tank 11. With this configuration, the purified water tank 11 and the raw water tank 12 are designed to be detachable. The detachable installation on the side of the unit 1 not only facilitates independent cleaning, maintenance, or replacement by users, improving the convenience and hygiene of equipment maintenance, but also allows the deeply purified water tank 11 to be directly removed as an independent water container, making it convenient for users to use in kitchen cooking scenarios such as making soup and cooking rice, greatly expanding the multi-functionality of the equipment for home use; at the same time, its water purification system adopts a multi-stage filtration module including a pre-filter, an RO filter, and a post-filter, driven by a booster pump 73, ensuring the high purity and excellent taste of the produced purified water, and guaranteeing the healthy quality of drinking and cooking water from the source.

[0063] See Figures 1 to 8In one embodiment, the raw water tank 12 is provided with a raw water chamber 121 and a wastewater chamber 122 arranged separately, and the raw water chamber 121 and the wastewater chamber 122 are interconnected at the top. The water purification system also includes a wastewater valve (not shown in the figure), which is used to transport the wastewater generated by the RO filter module 72 to the wastewater chamber 122. With this configuration, by setting the raw water chamber 121 and the wastewater chamber 122 interconnected in the raw water tank 12, and using the wastewater valve to directly recover the wastewater generated by the RO filter module 72 to the wastewater chamber 122, the wastewater is centrally stored and isolated inside the raw water tank 12, avoiding the space occupation of an additional independent wastewater tank, making the overall structure more compact. At the same time, the design of the top connection allows the raw water chamber 121 to be supplemented from the wastewater chamber 122 when the water volume is insufficient, optimizing the raw water utilization efficiency, reducing the number of times water is added, and improving the user convenience and the integration level of the equipment.

[0064] See Figures 1 to 6 In one embodiment, the body 1 is equipped with a water outlet solenoid valve 15 controlled by a control module. The water outlet 13 is connected to the cold water pump 42 and the hot water pump 32 respectively through the water outlet solenoid valve 15. By setting up the water outlet solenoid valve 15, which is uniformly controlled by the control module, and using it as a common path switching node for the cold water pump 42 and the hot water pump 32 to drain water to the water outlet 13, centralized, fast and reliable path management for multiple water temperature output modes is achieved. The control module can control the opening and closing of the solenoid valve in real time and accurately according to the instructions. This not only ensures that the required temperature of water is output instantly from a single water outlet 13 with a fast response speed, but also quickly cuts off the water flow when water is taken out, effectively avoiding the delayed dripping of residual water in the pipeline due to siphon or gravity. Thus, while improving the accuracy of water output response and the user's immediate experience, it also enhances the cleanliness and safety of use.

[0065] See Figures 1 to 6 In a further embodiment, a cup holder 16 is provided on the rear side below the water outlet 13 of the body 1. The upper end of the cup holder 16 is connected to the body 1 via an inverted U-shaped elastic element 17. The inner side of the inverted U-shaped elastic element 17 is provided with a touch switch 18 electrically connected to the water outlet solenoid valve 15. The touch switch 18 is preferably a micro switch. When the cup holder 16 is pushed backward into place, one of the elastic arms of the inverted U-shaped elastic element 17 abuts against the touch switch 18, thereby activating the water outlet solenoid valve 15 to continuously release drinking water of the currently selected temperature from the water outlet 13. When the cup holder 16 is released and reset, the elastic arm of the inverted U-shaped elastic element 17 simultaneously resets elastically and pushes against the touch switch 18, causing the water outlet solenoid valve to stop discharging water.

[0066] Example 2:

[0067] See Figures 1 to 16 The control method for the countertop water purifier in this embodiment includes the countertop water purifier of Embodiment 1. The human-machine interaction module 2 includes a human-machine interaction interface. The human-machine interaction interface, as the main interface, has a temperature selection area, a water output selection area, a water dispensing button, an ice dispensing button, and displays the TDS value of the water in the purified water tank 11 and the TDS value of the water in the raw water tank 12, such as... Figure 12 As shown.

[0068] The temperature selection area includes ice water, room temperature, warm water, hot water, and boiling water buttons. The specific temperatures for the room temperature, warm water, hot water, and boiling water buttons can be preset in the human-computer interaction module 2. This preset setting can be achieved using existing technologies. For example, the temperature of the warm water button can be set to 45℃, the hot water button to 75℃, and the boiling water button to 98℃.

[0069] The water dispensing selection area includes buttons for small cup, medium cup, large cup, and continuous dispensing.

[0070] After selecting the desired drinking water temperature in the temperature selection area and the desired drinking water volume in the water dispensing volume selection area, you can obtain drinking water of the corresponding temperature and volume by pressing the water dispensing button.

[0071] You can obtain a set number of ice cubes by pressing the ice dispensing button.

[0072] The aforementioned control method for the countertop water purifier clearly divides the temperature selection area and the water volume selection area on the integrated human-machine interface. This allows users to obtain drinking water with precise temperature and volume with a simple button combination, such as first selecting the temperature and cup volume, and then pressing the water dispensing button. Alternatively, the ice dispensing function can be operated independently with a single button. This greatly simplifies the operation process from selection to execution, reduces the user's learning cost, and enables one-button quick access to room temperature, ice water, multiple levels of hot water, and a fixed amount of ice cubes. This enhances the intuitiveness of the human-machine interface and the overall convenience of using the machine.

[0073] See Figure 13In one embodiment, the human-computer interaction module 2 is configured with at least one custom module. The custom module includes a custom button configured on the human-computer interaction interface. When the custom button is selected, the human-computer interaction interface displays a custom temperature selection area with an adjustment accuracy of 1°C. After the user selects a custom water temperature value in the custom temperature selection area and a custom water volume in the water volume selection area, the custom water temperature value and the custom water volume are saved in the custom module. This allows the user to obtain drinking water with the corresponding temperature and volume saved in the custom module by touching the custom button and the water dispensing button. By setting at least one custom module that supports 1°C precision adjustment in the human-computer interaction interface, users can accurately set and store their own exclusive combination of water temperature and volume according to their personal preferences. Afterwards, they only need to trigger the corresponding custom button and the water dispensing button to reproduce the personalized settings with one click, eliminating the tediousness of repeatedly performing multiple steps of adjustment each time. This not only achieves highly personalized drinking water customization, but also significantly improves the operational efficiency and convenience of high-frequency or fixed drinking water needs.

[0074] See Figure 14 In one embodiment, the ice basket 62 is equipped with an ice block height detector (not shown) for detecting the stacking height of ice blocks. The human-machine interface also includes a quick refrigeration setting button. Clicking the quick refrigeration setting button allows the human-machine interface to enter the quick setting interface for ice water and ice blocks. The quick setting interface for ice water and ice blocks includes an ice water switch button, an ice block switch button, a return to main interface button, an ice-making mode selection area, and an ice-making progress display bar. The ice-making mode selection area includes a cotton-feel ice button and a transparent ice button. The ice-making progress display bar is used to display the detection information fed back by the ice block height detector. By installing an ice height detector inside the ice basket 62 and using a dedicated refrigeration quick settings interface on the human-machine interface, users can easily access and intuitively control the ice water and ice cube functions with a single click. Independent management of the ice water and ice cube switches, along with quick switching between cotton-feel ice and transparent ice modes, and a real-time display bar showing the ice stack height, allows for centralized monitoring and convenient management of ice water supply and ice production capacity. This not only satisfies users' personalized choices of ice feel types but also enhances the visualization of ice storage and the controllability of the ice-making process, thus optimizing the user experience.

[0075] When the ice block height detector detects that the stack height of the prepared ice blocks has reached the preset height, the ice-making progress display bar shows 100%. When the ice block height detector detects that the stack height of the prepared ice blocks has reached half of the preset height, the ice-making progress display bar shows 50%. The detection of the stack height of the ice blocks by the ice block height detector can be achieved by existing technical means.

[0076] In one embodiment, the quick setting interface for ice water and ice cubes also includes an ice hopper emptying button. When the ice hopper emptying button is activated by touch, the ice cube ejection mechanism 6 works continuously until the ice cubes in the ice basket 62 are completely emptied and then stops working.

[0077] See Figures 15 to 17 In one embodiment, the human-computer interaction interface further includes a device settings button. Clicking the device settings button allows the human-computer interaction interface to enter the device settings interface. The device settings interface includes a settings selection area on one side and an operation display area on the other side corresponding to the settings selection area. The settings selection area includes at least an energy-saving settings button. When the energy-saving settings button is selected, the operation display area enters the energy-saving settings operation display area. The energy-saving settings operation display area includes an ice cube timer switch button and an ice water timer switch button. By sequentially touching the ice cube timer switch button or the ice water timer switch button, the ice cube timer function or the ice water timer function can be turned on or off. When the ice cube timer function or the ice water timer function is on, the energy-saving settings operation display area displays the ice cube start / stop function that can be operated by the user. The stop timer operation area or the ice water start / stop timer operation area allows users to access the ice cube or ice water start / stop timer settings interface via the human-machine interface. This setup, with its clearly hierarchical device settings menu and dedicated energy-saving options, allows users to independently activate the timer function for ice cubes or ice water, and customize specific start / stop time periods. This enables users to precisely plan the operation of the refrigeration equipment, such as pausing ice making at night. This not only effectively avoids energy waste during periods of low usage or demand but also significantly reduces noise generated during nighttime ice making, creating a quiet resting environment. Thus, while improving the intelligent management and operational efficiency of the equipment, it also optimizes the user's comfort.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
