Description

Technical Field

[0001] This invention relates to an ice maker that can be used to make both smoothies and ice cubes. Background Technology

[0002] Currently, most ice makers on the market suffer from limited functionality. Most can only produce one type of ice, whether it's the common cube ice or cylindrical ice, limiting them to a single form. However, different users have vastly different usage scenarios and preferences. For example, cafes need crushed ice to make iced coffee to enhance its flavor; hot pot restaurants prefer large blocks of ice for preserving food; and families may prefer small, granular ice for easy consumption. The limited ice-producing capabilities of existing ice makers clearly cannot meet these diverse and personalized needs, requiring technological improvements and breakthroughs. Summary of the Invention

[0003] To address the shortcomings mentioned above, this invention provides an ice maker that can simultaneously make smoothies and ice cubes.

[0004] To achieve the above objectives, the present invention provides an ice maker that can be used to make both smoothies and ice cubes, comprising a compressor, a condenser, a first evaporator for making ice cubes, a second evaporator for making smoothies, a plurality of dryer filters and a plurality of three-position three-way solenoid valves provided on the refrigerant pipes, the first evaporator being connected to the output end of the compressor via a hot gas delivery pipe, the hot gas delivery pipe being provided with a hot gas valve for flow control, and the second evaporator including a rotatable scraper on its surface.

[0005] Furthermore, the hot gas delivery pipe is connected to the refrigerant pipe disposed between the compressor and the condenser via a tee connector.

[0006] Furthermore, the scraper is driven to rotate by a motor to scrape off the ice crystals formed on the surface of the second evaporator in a timely manner, thus obtaining shaved ice.

[0007] Furthermore, there are two of each of the drying filter and the three-position three-way solenoid valve.

[0008] Furthermore, the three-position three-way solenoid valve includes a valve body, a valve core placed inside the valve body, a connecting hole formed in the middle of the valve core, iron cores and springs provided on both sides of the valve core, three connectors formed on the valve body, and coils formed on both sides of the valve body.

[0009] The advantages of this invention over the prior art are as follows:

[0010] By controlling two three-position three-way solenoid valves, the ice maker can make the first evaporator and the second evaporator work independently or simultaneously. That is, the ice maker has three modes: making ice cubes alone, making ice smoothies alone, and making ice cubes and ice smoothies simultaneously, to meet the needs of actual use scenarios.

[0016] like Figures 1-4 As shown, an ice maker according to an embodiment of the present invention, which can be used to make both smoothies and ice cubes, includes a compressor 2, a condenser 4, a first evaporator 8 for making ice cubes, a second evaporator 9 for making smoothies, a plurality of dryer filters 10 and a plurality of three-position three-way solenoid valves 3 connected by a refrigerant pipe 1. The first evaporator 8 is connected to the output end of the compressor 2 through a hot gas delivery pipe 7, and a hot gas valve 6 for flow control is provided on the hot gas delivery pipe 7. The second evaporator 9 includes a rotatable scraper on its surface; the hot gas delivery pipe 7 is connected by a refrigerant pipe 1. A three-way connector 5 is connected to the refrigerant pipe 1 configured between the compressor 2 and the condenser 4; the scraper is driven by a motor to rotate, so as to scrape off the ice crystals formed on the surface of the second evaporator 9 in time to obtain ice sand; there are two dryer filters 10 and two three-position three-way solenoid valves 3; the three-position three-way solenoid valve 3 includes a valve body 31 and a valve core 32 placed in the valve body 31. A connecting hole 321 is formed in the middle of the valve core 32. Iron cores 322 and springs 323 are provided on both sides of the valve core 32. Three connectors 311 are formed on the valve body 31. Coils 312 are formed on both sides of the valve body 31.

[0017] By controlling two three-position three-way solenoid valves, the ice maker can make the first evaporator and the second evaporator work independently or simultaneously. That is, the ice maker has three modes: making ice cubes alone, making ice smoothies alone, and making ice cubes and ice smoothies simultaneously, to meet the needs of actual use scenarios.

[0018] In practical use, the invention will be described in conjunction with the accompanying drawings for ease of understanding;

[0019] like Figure 2 As shown, at this time, neither of the two coils 312 is energized, the valve core 32 of the three-position three-way solenoid valve 3 is in the middle position, and the three connectors 311 are connected to each other, corresponding to the ice maker mode of simultaneously making ice cubes and shaved ice; at the second evaporator 9, the ice crystals formed on the surface of the second evaporator 9 are scraped off in time by the scraper driven by the motor to obtain shaved ice; at the first evaporator 8, when ice cubes such as bullet ice or block ice are formed, the hot gas valve 6 automatically opens, so that the high temperature gas of the compressor 2 flows into the first evaporator 8 to achieve rapid de-icing. After de-icing is completed, the hot gas valve 6 automatically closes.

[0020] like Figure 3 As shown, at this time, the coil 312 on the right is energized, the valve core 32 moves to the right, and two of the three connectors 311 are connected. Corresponding to the ice maker, at the three-position three-way solenoid valve 3, along the flow direction of the refrigerant, one pipe is in a flowing state, and the other pipe is in a closed state. In this way, only one of the first evaporator 8 and the second evaporator 9 works normally, that is, the ice maker is in the single ice cube making mode or the single ice slush making mode.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
