Description

Technical Field

[0001] This invention relates to the field of household ice makers, and specifically to a household ice maker. Background Technology

[0002] Currently, when people want to drink beverages like milk tea, they can make them themselves using equipment such as ice makers, a healthy and economical method. Typically, an ice maker is a device that produces ice by cooling supplied ice-making water. A traditional ice maker consists of a main body and an ice-making unit. The main body includes an ice storage device that stores the ice produced in the ice-making unit. The ice-making unit includes an ice-making plate, a cooling plate, and evaporator tubes. Ice-making water fills the ice-making plate, and multiple cooling protrusions immersed in the ice-making water are mounted on the lower surface of the cooling plate. Evaporator tubes are mounted on the upper surface of the cooling plate and connected to the refrigeration system. Refrigerant flows in the evaporator tubes and cooling plate, and the cooling protrusions are cooled through heat exchange with the refrigerant. The internal heat dissipation efficiency also affects the refrigeration efficiency. Current household refrigeration machines, due to size and cost limitations, have not effectively adjusted the heat dissipation fan speed, resulting in poor heat dissipation efficiency. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a household ice maker that solves the shortcomings of existing household refrigerators, which, due to size and cost limitations, cannot effectively adjust the cooling fan speed and have poor cooling efficiency.

[0004] The technical solution adopted in this invention is as follows: A household ice maker includes: a body with a storage cavity inside; an air inlet grille below the storage cavity; an exhaust fan below the air inlet grille; a drive motor mounted on the exhaust fan; blades mounted on the outer side of the drive motor; a fixed cylinder mounted on the inner side of the drive motor near the housing; a movable rod inserted into the fixed cylinder; a parapet on the movable rod; a first spring between the end of the movable rod and the bottom wall of the fixed cylinder; a first piston plate mounted in the middle of the first spring; a resistor plate on each of the upper and lower sides of the fixed cylinder; a conductive ring at the bottom of the movable rod; a resistor plate on the upper part of the fixed cylinder connected in series with the drive motor; the drive motor being connected to one pole of an external power supply; and another resistor plate on the lower part of the fixed cylinder being connected to the other pole of an external power supply. A damping grease, which is gel-like at room temperature, is filled between the first piston plate and the bottom of the fixed cylinder. The damping grease melts into a liquid between 30-40°C. Multiple grease reservoirs are located at the bottom of the fixed cylinder, with a second piston plate at the bottom of each reservoir. A second spring is located between the second piston plate and the bottom wall of the grease reservoir.

[0005] In this invention, the exhaust fan guides the airflow from the intake grille through the heating element and then out through the exhaust end of the exhaust fan. The airflow at the intake end of the exhaust fan drives the umbrella wing and movable rod to move inward towards the inside of the fixed cylinder. When the gas temperature at the intake end of the exhaust fan exceeds the melting temperature of the damping grease, the damping grease melts into a liquid, reducing the resistance of the first piston plate and allowing the exhaust fan's wind speed to reach its initial rated value. This allows the first piston plate to move further inward, causing the conductive ring to move to the side of the conductive plate closer to the exhaust end of the exhaust fan. At this time, because a resistor located on the upper part of the fixed cylinder is connected in series with a drive motor, and the drive motor is connected to one pole of an external power supply, and another resistor located on the lower part of the fixed cylinder is connected to the other pole of an external power supply, the resistance value in the power supply decreases, thereby increasing the output power of the exhaust fan, increasing the wind speed, and improving the heat dissipation efficiency. This allows the exhaust fan power to be automatically adjusted according to the temperature of the air outlet and the preset wind speed. The structure is simple and the cost is low. This invention solves the problem that existing household refrigerators, due to size and cost limitations, cannot effectively adjust the cooling fan speed and have poor cooling efficiency.

[0006] Optionally, the air intake grille is equipped with a hollow rotating shaft, and the rotating shaft is equipped with grille blades.

[0007] Optionally, the housing is provided with a water storage tank, and the water storage tank is connected to an outlet pipe and a return pipe. A water pump is installed on the outlet pipe.

[0008] Optionally, the first spring is hollow.

[0009] Optionally, the outlet pipe is connected to the first spring and the rotating shaft in series via a flexible hose and then to the return pipe.

[0010] Optionally, the return pipe is configured to flow through the heating element within the machine body.

[0011] Optionally, the movable rod is provided with a sliding groove, and the fixed cylinder is provided with a limiting block that inserts into the sliding groove. The present invention includes a water storage tank inside the housing, with an outlet pipe and a return pipe connected to the outside of the water storage tank. A water pump is installed on the outlet pipe. The outlet pipe is connected to the first spring and the rotating shaft via a flexible hose and then to the return pipe. The return pipe is configured to flow through the heating parts inside the machine body. Due to the higher specific heat capacity of water, the heat from the heating parts is quickly carried away through the rotating shaft and the spring. The water flow also rapidly conducts heat from the heat dissipation components to the damping grease, causing the damping grease to melt more quickly. Furthermore, the circulating water flow further improves the heat dissipation efficiency.

[0012] (III) Beneficial Effects 1. In this invention, the exhaust fan guides the airflow from the intake grille through the heating element and then out through the exhaust end of the exhaust fan. The airflow at the intake end of the exhaust fan drives the umbrella wing and movable rod to move inward toward the inside of the fixed cylinder. When the gas temperature at the intake end of the exhaust fan exceeds the melting temperature of the damping grease, the damping grease melts into a liquid, reducing the moving resistance of the first piston plate and allowing the exhaust fan's wind speed to reach its initial rated value. This allows the first piston plate to move further inward, causing the conductive ring to move to the side of the conductive plate closer to the exhaust end of the exhaust fan. At this time, because a resistor located on the upper part of the fixed cylinder is connected in series with a drive motor, and the drive motor is connected to one pole of an external power supply, and another resistor located on the lower part of the fixed cylinder is connected to the other pole of an external power supply, the resistance value in the power supply becomes smaller, thereby increasing the output power of the exhaust fan, increasing the wind speed, and improving the heat dissipation efficiency. This allows the exhaust fan power to be automatically adjusted according to the temperature of the air outlet and the preset wind speed. The structure is simple and the cost is low.

[0013] 2. This invention includes a water storage tank inside the casing, with an outlet pipe and a return pipe connected to the outside of the tank. A water pump is installed on the outlet pipe. The outlet pipe is connected to a first spring and a rotating shaft via a flexible hose and then to the return pipe. The return pipe is configured to flow through the heating parts inside the machine body. Due to the higher specific heat capacity of water, the heat from the heating parts is quickly carried away through the rotating shaft and spring. The water flow also rapidly conducts the heat from the heat dissipation components to the damping grease, causing the damping grease to melt more quickly. Furthermore, the circulating water flow further improves the heat dissipation efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] Example 1

[0019] The technical solution adopted in this invention is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this invention discloses a household ice maker, comprising: a body 1, a storage cavity 2 within the body, an air inlet grille 3 located below the storage cavity, an exhaust fan 4 located below the air inlet grille, a drive motor 5 mounted on the exhaust fan, blades 6 mounted on the outer side of the drive motor, a fixed cylinder 7 mounted on the inner side of the drive motor near the housing, a movable rod 8 inserted into the fixed cylinder, a parapet 9 mounted on the movable rod, a first spring 10 mounted between the end of the movable rod and the bottom wall of the fixed cylinder, a first piston plate 11 mounted in the middle of the first spring, and the upper and lower sides of the fixed cylinder... Each component is equipped with a resistor 12. A conductive ring 13 is located at the bottom of the movable rod. One resistor located on the upper part of the fixed cylinder is connected in series with a drive motor, which is connected to one pole of an external power supply. Another resistor located on the lower part of the fixed cylinder is connected to the other pole of an external power supply. The space between the first piston plate and the bottom of the fixed cylinder is filled with damping grease, which is gel-like at room temperature and melts into a liquid between 30-40°C. The bottom of the fixed cylinder has multiple grease reservoirs 14, and a second piston plate 15 is located at the bottom of each reservoir. A second spring 16 is located between the second piston plate and the bottom wall of the reservoir. The outer side of the first piston plate is covered with a sealing block to increase resistance and sealing.

[0020] The air intake grille is equipped with a hollow rotating shaft 17, and grille blades 18 are mounted on the rotating shaft. A water storage tank 19 is located inside the housing, and an outlet pipe 20 and a return pipe 21 are connected to the outside of the water storage tank. A water pump 22 is mounted on the outlet pipe. The first spring is hollow. The outlet pipe is connected to the first spring and the rotating shaft in series via a flexible hose 23 and is connected to the return pipe. The return pipe is configured to flow through the heating components inside the machine body. The movable rod is provided with a sliding groove 24, and the fixed cylinder is provided with a limiting block 25 that inserts into the sliding groove.

[0021] In this embodiment, the exhaust fan guides the airflow from the intake grille through the heating element and then out through the exhaust end of the exhaust fan. The airflow at the intake end of the exhaust fan drives the umbrella wing and movable rod to move inward towards the inside of the fixed cylinder. When the gas temperature at the intake end of the exhaust fan exceeds the melting temperature of the damping grease, the damping grease melts into a liquid, reducing the moving resistance of the first piston plate and allowing the exhaust fan's wind speed to reach its initial rated value. This allows the first piston plate to move further inward, causing the conductive ring to move to the side of the conductive plate closer to the exhaust end of the exhaust fan. At this time, because a resistor located on the upper part of the fixed cylinder is connected in series with a drive motor, and the drive motor is connected to one pole of an external power supply, and another resistor located on the lower part of the fixed cylinder is connected to the other pole of an external power supply, the resistance value in the power supply becomes smaller, thereby increasing the output power of the exhaust fan, increasing the wind speed, and improving the heat dissipation efficiency. This allows the exhaust fan power to be automatically adjusted according to the temperature of the air outlet and the preset wind speed.

[0022] The water outlet pipe is connected to the first spring and the rotating shaft via a flexible hose and then to the return pipe. The return pipe is configured to flow through the heating parts inside the machine. Because water has a higher specific heat capacity, the heat from the heating parts passes through the rotating shaft and the spring, quickly carrying away the heat. The water flow also quickly conducts the heat from the heat dissipation components to the damping grease, causing the damping grease to melt more quickly. Furthermore, the circulating water flow further improves the heat dissipation efficiency.

[0023] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
