Description
[Technical Field]
[0001] This utility model relates to ice-making technology, and more particularly to an ice-making system and its household ice maker. [Background Technology]
[0002] A household ice maker is a refrigeration device that produces ice by cooling water through an evaporator with a refrigerant in a refrigeration system. It uses a refrigeration system with water as the carrier, and ice is produced by condensing water through an ice-making column connected to the evaporator when the device is powered on.
[0003] However, current household ice makers on the market are complex in structure, large in size, and have limited functions. With the development of technology, there are more and more types of ice-making equipment available, and their functions are no longer limited. Especially in some office or meeting places, different groups of consumers no longer just need to satisfy the single function of ice making. For example, some people need to drink boiled water, some people need drinks with ice, and children are used to filtered room temperature water, etc. There is an urgent need for an ice-making device that can integrate direct drinking, heating, cooling, or ice making, so as to meet the diverse needs of different consumers. [Utility Model Content]
[0004] This utility model provides an ice-making system and its household ice maker, which integrates water heating, room temperature water, cooling water and ice making to meet various consumer needs.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An ice-making system includes a raw water tank, a compressor, an air-cooled condenser, a condensate collection box, a dryer and capillary tube, an evaporator, an ice tray, an ice storage chamber, and a cold water tank. The compressor, condenser, dryer and capillary tube, and evaporator are connected in series via refrigerant pipelines.
[0007] The condensate collection box is installed on the lower side of the condenser and is used to collect the condensate generated during the refrigeration / ice-making process.
[0008] The ice tray is installed at the ice-making column on the lower side of the evaporator;
[0009] The cold water tank and the ice tray are connected by a pipeline to a first self-priming pump that draws water from the cold water tank into the ice tray to make ice. The cold water tank and the ice tray are also connected by a return pipe that returns the ice water in the ice-water mixture after ice making to the cold water tank.
[0010] The bottom of the ice storage chamber is also connected to an emptying pipe for discharging ice water from the chamber into the cold water tank.
[0011] A water supply pipeline for replenishing water to the cold water tank is also provided between the raw water tank and the cold water tank. The water supply pipeline is equipped with a second self-priming pump that pumps pure water out of the raw water tank and a first inlet solenoid valve that controls the opening and closing of the pipeline.
[0012] Preferably, the cold water tank is also connected to a third self-priming pump via a pipeline to supply ice water to the outside.
[0013] Preferably, both the cold water tank and the ice storage cavity are equipped with antibacterial lamps on their top sides to prevent the growth of bacteria inside the cavity.
[0014] Preferably, a spiral cooling pipe extending into the cold water tank for storing ice water for cooling is also connected to the return pipe between the evaporator and the compressor.
[0015] Preferably, the cold water tank is also equipped with a dual-level float switch for detecting the liquid level inside the tank.
[0016] Preferably, the second self-priming pump on the water supply pipeline is further branched off to a branch pipeline that pumps the raw water tank out through the second self-priming pump and supplies room temperature water or hot water to the outside. The branch pipeline is sequentially connected to a second inlet solenoid valve for controlling the on / off of the pipeline and an instant heating pipe for heating the supplied pure water when hot water is needed.
[0017] A household ice maker employs the aforementioned ice-making system. The household ice maker includes a shell, a base, a compressor, an air-cooled condenser, an evaporator, an ice tray, a stepper drive motor, an ice storage chamber, and a cold water tank.
[0018] The ice storage chamber is installed on the upper side of the cold water tank, and the outer walls of both chambers are wrapped with EVA insulation cotton.
[0019] The ice tray rotates on the upper side of the ice storage cavity via a motor bracket. The stepper drive motor is installed at one end of the motor bracket and drives the ice tray to deflect, pouring the prepared ice blocks into the lower ice storage cavity.
[0020] The evaporator is installed on the upper side of the ice tray via a refrigerant pipeline, and the condenser is installed on the lower side of the ice tray. An instant heating pipe for heating the supplied pure water when hot water is needed is also installed at one end of the condenser on the lower side of the ice tray.
[0021] The compressor is installed on the lower side of the cold water tank. A condensate collection box for collecting condensate produced by the condenser is provided next to the compressor. A water circuit board assembly is also installed on the lower side of the condenser next to the compressor.
[0022] Preferably, a cooling fan is installed on the side of the condenser to circulate air and cool it.
[0023] The beneficial effects of this utility model are:
[0024] In this invention, the condenser and compressor are installed on the lower side of the whole machine, and the ice tray, ice storage cavity and cold water tank are installed on the lower side of the evaporator in sequence. After the ice is made, the ice water produced can be directly returned to the cold water tank, and the ice in the ice tray can be directly poured into the ice storage cavity for storage. The overall layout is reasonable and effectively reduces the size of the whole machine.
[0025] Furthermore, the ice-making system incorporates a condensate collection box. The ice-making module directs all the condensate from the module into the collection box. The condensate in the collection box evaporates more quickly due to the condenser's heating, preventing it from dripping onto the outside of the machine. At the same time, the condenser cools down using the condensate in the collection box, increasing its heat dissipation effect. During ice making, the collected condensate helps cool the system. The entire machine integrates heating, cooling, and ice-making functions, supporting both water heating and ice-making processes. [Attached Image Description]

[0033] An ice-making system, such as Figure 1 As shown, the system includes a raw water tank 1, a compressor 2, an air-cooled condenser 3, a condensate collection box 4, a dryer and capillary tube 5, an evaporator 6, an ice tray 7, an ice storage chamber 8, and a cold water tank 9. The compressor 2, condenser 3, dryer and capillary tube 5, and evaporator 6 are connected in series via refrigerant piping. The condensate collection box 4 is installed below the condenser 3 to collect condensate generated during the refrigeration / ice-making process. The ice tray 7 supports the ice-making column installed below the evaporator 6. A piping connection is provided between the cold water tank 9 and the ice tray 7 to draw water from the cold water tank 9 into the ice tray 7 for ice making. A first self-priming pump 10 is connected to the cold water tank 9 and the ice tray 7 via a return pipe 11 that returns the ice water in the ice-water mixture after ice making in the ice tray 7 to the cold water tank 9. A drain pipe 12 for discharging the ice water in the ice storage cavity 8 to the cold water tank 9 is also connected to the bottom side of the ice storage cavity 8. A water supply pipe 13 for replenishing water to the cold water tank 9 is also provided between the raw water tank 1 and the cold water tank 9. A second self-priming pump 14 for pumping pure water out of the raw water tank 1 and a first inlet solenoid valve 15 for controlling the opening and closing of the pipe are installed on the water supply pipe 13. The cold water tank 9 is also connected to a third self-priming pump 16 for supplying ice water to the outside via a pipe.
[0034] Continue as Figure 1 As shown, a branch line 17 is connected to the rear side of the second self-priming pump 14 on the water supply line 13. The second self-priming pump 14 pumps the raw water tank 1 out and supplies room temperature water or hot water to the outside. The branch line 17 is connected in sequence to a second inlet solenoid valve 18 that controls the opening and closing of the pipeline and an instant heating pipe 19 that heats the supplied pure water when hot water is needed. When room temperature water is needed, the second inlet solenoid valve 18 is opened and the instant heating pipe 19 stops working. The branch line 17 can then directly pump the pure water out of the raw water tank 1 for use.
[0035] like Figure 1 As shown, antibacterial lamps 20 are installed on the top side of both the cold water tank 9 and the ice storage chamber 8 to prevent the growth of bacteria in the chamber. A spiral cooling pipe 21 that extends into the cold water tank 9 for storing ice water and cooling is also connected to the return pipe 11 between the evaporator 6 and the compressor 2. A dual liquid level float switch 22 is also installed in the cold water tank 9 to detect the liquid level in the tank.
[0036] The corresponding home ice maker for this ice-making system is, for example... Figure 2 and Figure 3 As shown, the system includes an outer shell (not shown), a base 23, a compressor 2, an air-cooled condenser 3, an evaporator 6, an ice tray 7, a stepper drive motor 24, an ice storage chamber 8, and a cold water tank 9. The ice storage chamber 8 is installed on the upper side of the cold water tank 9, and the outer walls of both chambers are wrapped with EVA insulation cotton 25. The ice tray 7 rotates on the upper side of the ice storage chamber 8 via a motor bracket. The stepper drive motor 24 is installed at one end of the motor bracket and drives the ice tray 7 to deflect, pouring the ice blocks into the lower ice storage chamber 8. The evaporator 6 is installed on the upper side of the ice tray 7 via a refrigerant pipeline, and the condenser 3 is installed on the lower side of the ice tray 7. An instant heating pipe 19 for heating the supplied pure water when hot water is needed is also installed at one end of the condenser 3 on the lower side of the ice tray 7. The compressor 2 is installed on the lower side of the cold water tank 9. A condensate collection box 4 for collecting the condensate produced by the condenser 3 is provided next to the compressor 2. A water circuit board assembly 26 is also installed on the lower side of the condenser 3 next to the compressor 2.
[0037] In this embodiment, the condenser 3 and compressor 2 are installed on the lower side of the entire machine. The ice tray 7, ice storage chamber 8, and cold water tank 9 are installed in a stepped manner below the evaporator 6 from high to low. After the ice is made, the ice water in the ice tray 7 can flow directly back to the cold water tank 9, and the ice in the ice tray 7 can be directly poured into the ice storage chamber 8 for storage. The overall layout is reasonable and effectively reduces the size of the entire machine. Moreover, when ice water is needed, the ice water in the cold water tank 9 can be pumped directly to the outside through the third self-priming pump 16. At the same time, a condensate collection box 4 is added to the ice-making system. The ice-making module guides the condensate on the module to the condensate collection box 4 to prevent the condensate from dripping onto the outside of the machine. The condensate in the condensate collection box 4 is heated by the condenser 3, which accelerates the evaporation of the condensate and increases the heat dissipation effect of the condenser 3, thus cooling the system during ice making. The entire machine integrates heating, cooling, and ice-making functions, realizing multiple uses in one machine and effectively improving the utilization rate of the equipment.
[0038] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any obvious changes made to the shape, structure and principle of this utility model, as well as any other modifications that do not depart from the essence of this utility model, should be covered within the protection scope of this utility model.
