Description

[Technical field]

[0001] The invention relates to ice making technology, and in particular to ice making equipment and a control system thereof, and an ice water and ice cube preparation control method. [Background technology]

[0002] An ice maker is a refrigeration device that passes water through an evaporator and is cooled by the refrigerant in the refrigeration system to generate ice. The existing ice maker mostly makes ice in the following way: the ice column of the evaporator is immersed in an ice water box. After the ice water box is filled with water, the ice evaporator starts to refrigerate, and the water cools and solidifies on the surface of the ice column in the ice water box to form ice cubes. When enough ice is condensed, the compressor is turned off to stop the refrigerant circulation. Then, the ice column is heated by an electric heater or by controlling the reverse flow of the refrigerant in the compressor to increase its temperature. The ice cubes attached to the ice column are melted by the heat and then separated from the ice column, completing the water discharge and ice removal.

[0003] Traditional ice machines have a single function and can only meet basic ice-making needs. They cannot achieve the function of preparing ice cubes and ice water at the same time. For many practical use scenarios, they can only mix room temperature water with ice cubes to obtain ice water, which is extremely inconvenient. Moreover, in existing ice machines, the size of ice particles produced in the initial rounds is greatly affected by the water temperature. When the water temperature is high, the ice particles produced are small and not full, making the ice cubes easy to melt when used and not durable. At the same time, the existing ice-making system is not convenient for defrosting, and the energy generated by the compressor during defrosting cannot be effectively utilized and is wasted. [Summary of the invention]

[0004] The present invention provides an ice-making device and a control system thereof and a method for controlling the preparation of ice water and ice cubes. By adjusting the pipeline connection, water temperature pre-cooling control is achieved, the energy generated in the process of ice making or ice-removing is effectively utilized, energy is saved, the fullness of ice particles made is effectively improved, and ice cubes and ice water are output at the same time.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is:

[0006] An ice-making device, comprising a base, a compressor, an ice-making body, a condenser, an evaporator, a main control box, a shell and a top cover, wherein the ice-making body is an L-shaped inverted bucket structure, the bottom side of the ice-making body is fixed to one side of the base, the compressor is installed on the other side of the base, and the condenser and the main control box are installed in the internal cavity of the lower side of the ice-making body beside the compressor;

[0007] The evaporator is correspondingly installed on the top side of the refrigerator body;

[0008] The internal cavity at the lower side of the refrigerator body is also equipped with a main control box for controlling the whole machine, a bypass valve for controlling the bypass of the pipeline section corresponding to the condenser, and a three-way valve for controlling the refrigerant flowing out of the evaporator to directly flow back into the compressor or into the water tank coil arranged at the bottom of the refrigerator body;

[0009] The lower end of the shell abuts against the base along the circumferential direction, and circumferentially surrounds and covers the refrigerator body and the compressor and condenser installed on the base;

[0010] The top cover is installed on the top of the shell and seals the evaporator cover installed on the top of the refrigerator body.

[0011] Preferably, a water box for making ice through multiple ice-making columns on the lower side of the evaporator after water is injected is installed on the top of the refrigerator body corresponding to the lower side of the evaporator. The water box has a semicircular opening groove and is rotatably installed on the front and rear side walls of the refrigerator body at both ends along the axial direction. A deflection drive motor for driving the water box to deflect and obliquely discharge the ice cubes made in the water box is also installed on one side wall of the refrigerator body; a water pump is also installed at the bottom of the refrigerator body to pump the refrigerated water in the refrigerator body into the water box through a water pipe.

[0012] Preferably, the inner edge of the water box along the axial direction is also hingedly connected with a water filter guide plate for obliquely guiding out ice cubes in the water box or filtering the ice-water mixture obliquely poured out of the water box.

[0013] Preferably, the water box is also provided with a drain valve for draining the remaining water into the ice making ice box after ice is formed in the water box.

[0014] Preferably, a drainage pump is installed next to the side wall of the refrigerator body to pump out the remaining water in the water box after ice formation into the refrigerator body through a pumping pipe.

[0015] The control system of the ice-making equipment mentioned above comprises a compressor, a condenser, a capillary tube, an evaporator, a three-way valve and a water tank in the ice-making body, wherein the compressor, the condenser, the capillary tube and the evaporator are connected in sequence through pipelines, and the output pipeline of the evaporator is connected to the port a of the three-way valve as the input port;

[0016] The port b of the three-way valve as an output port is connected to a water tank coil provided in the water tank for cooling the stored water through a pipeline, and the water tank coil in the water tank is directly connected to the input port of the compressor through a pipeline;

[0017] The C port of the three-way valve as the output port is also directly connected to the input port of the compressor through a pipeline;

[0018] The pipelines corresponding to the condenser and the capillary tube are also connected in a bypass manner to pass the refrigerant discharged from the compressor directly to the evaporator for heating and deicing the ice-making column connected to the evaporator. A bypass valve for controlling the on-off of the pipeline is arranged on the bypass pipeline.

[0019] The ice water and ice cube preparation control method of the ice making equipment control system as described above comprises the following steps:

[0020] Step S1, the compressor is turned on, and the high-temperature exhaust gas generated by the compressor is cooled by the condenser to become a liquid refrigerant, and then throttled and depressurized by the capillary tube to absorb heat in the evaporator, so that the ice column of the evaporator is cooled to produce ice cubes;

[0021] Step S2, then, the temperature sensor detects whether the water temperature in the water tank is higher than the set temperature value T1+3°C;

[0022] Step S3, when the water temperature of the water tank is higher than the set temperature value T1+3°C, the port a of the three-way valve is controlled to be connected with the port b, and the refrigerant passing through the evaporator flows through the water tank coil in the water tank, and the water tank coil absorbs the heat of the water to cool the water in the water tank, so that the temperature of the water tank is lowered to produce ice water, and at this time, the ice cubes on the ice-making column and the ice water in the water tank are running at the same time;

[0023] Step S4, then, after working for a period of time and the water in the water tank cools down, the temperature sensor detects again whether the water temperature in the water tank is lower than the set temperature value T1;

[0024] At the same time, when the temperature sensor detects in step S2 that the water temperature in the water tank is lower than the set temperature value T1+3°C, further detect whether the water temperature in the water tank is lower than the set temperature value T1;

[0025] Step S5, when the water temperature in the water tank is greater than the set temperature T1, the port a of the three-way valve continues to be connected with the port b, the ice cubes on the ice-making column and the ice-making water in the water tank are operated simultaneously, and the refrigerant flows through the water tank coil and then flows back to the compressor. This operation mode can increase the ice-making speed and the fullness of the ice particles produced due to the pre-cooling of the water;

[0026] Step S6, when the water temperature in the water tank is not greater than the set temperature T1, since the ice water produced in the water tank meets the set temperature T1 requirement, the port a of the three-way valve is controlled to be connected with the port c, the refrigerant does not flow through the water tank coil, the ice water production at the water tank is stopped, and the refrigerant directly flows back to the compressor at the three-way valve;

[0027] Step S7, when de-icing is in progress,

[0028] The high-temperature exhaust gas generated by the compressor does not pass through the condenser, but directly enters the evaporator after passing through the bypass valve. The high-temperature gas increases the temperature of the ice-making column connected to the evaporator, thereby melting the inner layer of the ice-making column for making ice cubes, and directly separates from the ice-making column to make ice cubes;

[0029] Step S8, then, the temperature sensor detects whether the water temperature in the water tank is greater than the set temperature T1;

[0030] Step S9, when the water temperature in the water tank is greater than the set temperature T1, the port a of the three-way valve is connected to the port b, and the refrigerant passing through the evaporator flows through the water tank coil in the water tank, and the water tank coil absorbs the heat of the water to cool the water in the water tank, thereby reducing the temperature of the water tank and producing ice water;

[0031] Step S10, when the water temperature in the water tank is not greater than the set temperature T1, port a of the three-way valve is connected to port c, and the refrigerant does not flow through the water tank coil, but directly flows back to the compressor at the three-way valve.

[0032] The beneficial effects of the present invention are:

[0033] The three-way valve port b connected to the evaporator is connected to the water tank coil in the water tank at the bottom of the ice making body through a pipeline. When working, the water tank coil cools and cools the water stored in the water tank. In this way, before the water is pumped into the water box to make ice, the water can be cooled in advance to achieve the purpose of making ice water. In addition to the basic ice making function, the ice making device of the present invention also has an ice water making function. The corresponding ice making machine can directly output ice cubes and ice water. Moreover, by pre-cooling the water in the water tank, the speed of ice making and the fullness of ice particles can also be effectively improved.

[0034] Moreover, compared with the existing method of defrosting the ice on the ice column by using a heating device, a bypass pipeline is connected through the corresponding pipeline bypass of the condenser and the capillary tube, so that the refrigerant discharged from the compressor can be directly passed to the evaporator. Before the discharged refrigerant returns to the suction port of the compressor, the switching of the three-way valve port a, port b and port c can be controlled according to the water temperature in the water tank. The refrigerant absorbs the heat of the water through the water tank coil, and the water in the water tank is pre-cooled. Not only does it make the exhaust temperature higher, but it also allows the ice column to be heated and defrosted faster, effectively shortening the defrosting time.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] An ice making device, such as Figures 1 to 3 As shown, the refrigerator body 3 includes a base 1, a compressor 2, a refrigerator body 3, a condenser 4, an evaporator 5, a main control box 6, a shell 7 and a top cover 8. The refrigerator body 3 is an L-shaped inverted bucket structure. The bottom side of the refrigerator body 3 is fixed to one side of the base 1, the compressor 2 is installed on the other side of the base 1, and the condenser 4 and the main control box 6 are installed in the internal cavity of the lower side of the refrigerator body 3 next to the compressor 2; the evaporator 5 is correspondingly installed on the top side of the refrigerator body 3, and a main control box 6 for cooling the refrigerator body 3 is also installed in the internal cavity of the lower side of the refrigerator body 3. A main control box 6 for controlling the whole machine, a bypass valve 9 for controlling the bypass of the pipeline section corresponding to the condenser 4, and a three-way valve 10 for controlling the refrigerant flowing out of the evaporator 5 to directly flow back into the compressor 2 or into the water tank coil arranged at the bottom of the refrigerator body 3; the lower end of the outer shell 7 is circumferentially abutted against the base 1, and circumferentially surrounds and covers the refrigerator body 3 and the compressor 2 and condenser 4 installed on the base 1; the top cover 8 is installed at the top of the outer shell 7, and seals the evaporator 5 installed on the top of the refrigerator body 3.

[0046] Continue as Figures 1 to 3As shown, a water box 11 for making ice by filling water and passing through a plurality of ice-making columns on the lower side of the evaporator 5 is installed at the top of the refrigerator body 3 corresponding to the lower side of the evaporator 5. The water box 11 has a semicircular opening groove and is rotatably installed on the front and rear side walls of the refrigerator body 3 at both ends along the axial direction. A deflection drive motor 12 for driving the water box 11 to deflect and obliquely discharge the ice cubes made in the water box 11 is also installed on one side wall of the refrigerator body 3; a water pump 14 for pumping the refrigerated water in the refrigerator body 3 into the water box 11 through a water pipe 13 is also installed at the bottom of the refrigerator body 3; a water filter guide plate 15 for obliquely discharging the ice cubes in the water box 11 or filtering the ice-water mixture obliquely poured out of the water box 11 is also hingedly connected to the inner side edge of the water box 11 along the axial direction.

[0047] Of course, in order to better refrigerate the ice cubes on the ice making column, a drain valve (not shown in the figure) is also installed on the bottom side of the water box 11 for draining the remaining water after the water box 11 is frozen into the ice making refrigerator body 3. In this way, the ice cubes on the ice making column that are no longer growing can be cooled for a second time, effectively reducing the temperature of the ice cubes on the ice making column and improving the quality of the ice cubes. Of course, different from this embodiment, a drainage pump can also be installed beside the side wall of the ice making refrigerator body 3 to pump out the remaining water in the water box 11 after the ice is frozen into the ice making refrigerator body 3 through a pumping pipe, without draining water through a drain valve, and directly pumping out water through a drainage pump.

[0048] The control system corresponding to the ice making equipment, such as 4 to Figure 6 As shown, the control system includes a compressor 2, a condenser 4, a capillary tube 16, an evaporator 5, a three-way valve 10 and a water tank 17 in the refrigerator body. The compressor 2, the condenser 4, the capillary tube 16 and the evaporator 5 are connected in sequence through pipelines. The output pipeline of the evaporator 5 is connected to the port a of the three-way valve 10 as the input port; the port b of the three-way valve 10 as the output port is connected to the water tank coil (not shown in the figure) set in the water tank 17 for cooling the stored water through a pipeline, and the water tank coil in the water tank 17 is directly connected to the input port of the compressor 2 through a pipeline; the port C of the three-way valve 10 as the output port is also directly connected to the input port of the compressor 2 through a pipeline. The pipelines corresponding to the condenser 4 and the capillary tube 16 are also bypassed and connected to a bypass pipeline 18 for directly passing the refrigerant discharged from the compressor 2 to the evaporator 5 for heating and deicing the ice column connected to the evaporator 5, and a bypass valve 9 for controlling the on-off of the pipeline is set on the bypass pipeline 18.

[0049] As shown in Figure 4, when the ice making operation is performed alone, the high-temperature exhaust gas generated by the compressor 2 is cooled by the condenser 4 and becomes a liquid refrigerant, and then is throttled and reduced in pressure by the capillary 16 to the evaporator 5 to absorb heat, so that the ice column at the lower end of the evaporator 5 is cooled to make ice cubes; at this time, the a port of the three-way valve 10 is connected to the c port, and the refrigerant passing through the evaporator 5 directly flows back to the compressor 2.

[0050] As shown in Figure 5, when ice making and ice water making are running at the same time, the high-temperature exhaust gas generated by the compressor 2 is cooled by the condenser 4 and becomes a liquid refrigerant, and then throttled and reduced in pressure by the capillary 16 before absorbing heat in the evaporator 5, so that the ice column of the evaporator 5 is cooled to make ice cubes; at this time, the a port of the three-way valve 10 is connected with the b port, and the refrigerant passing through the evaporator 5 flows through the water tank coil, absorbs the heat of the water to cool the water in the water tank, and reduces the temperature of the water tank 17 to make ice water; then, the refrigerant flows through the water tank coil and flows back to the compressor 2. In this operating mode, before the water is pumped into the water box for ice making, the water tank coil pre-cools the water stored in the water tank in advance during operation, which can increase the ice making speed and increase the fullness of the ice particles made. At the same time, in addition to the basic ice making function, the ice making equipment also has the ice water making function, and the corresponding ice making machine can directly output ice cubes and ice water.

[0051] As shown in Figure 6, when entering the defrosting procedure, the bypass valve 9 is connected, and the high-temperature exhaust gas generated by the compressor 2 passes through the bypass valve 9 to the evaporator 5, heating the ice column to make the ice cubes fall off; at this time, the a port and the b port of the three-way valve 10 are connected, and the refrigerant passing through the evaporator 5 flows through the water tank coil, absorbing the heat of the water to cool the water in the water tank 17; at the same time, the temperature of the refrigerant returning to the compressor 2 increases, so that the exhaust gas temperature of the compressor 2 also increases, so that the defrosting temperature of the evaporator 5 increases, and the defrosting speed is faster. Since this defrosting mode uses the refrigerant to absorb the heat of the water in the water tank for heating the evaporator 5, the defrosting time can be shortened.

[0052] The control system corresponds to the ice water ice cube preparation control method, such as Figure 4 , Figure 5 and Figure 8 As shown, the following steps are included:

[0053] Step S1, the compressor is turned on, and the high-temperature exhaust gas generated by the compressor is cooled by the condenser to become a liquid refrigerant, and then throttled and depressurized by the capillary tube to absorb heat in the evaporator, so that the ice column of the evaporator is cooled to produce ice cubes;

[0054] Step S2, then, the temperature sensor detects whether the water temperature in the water tank is higher than the set temperature value T1+3°C;

[0055] Step S3, when the water temperature of the water tank is higher than the set temperature value T1+3°C, the port a of the three-way valve is controlled to be connected with the port b, and the refrigerant passing through the evaporator flows through the water tank coil in the water tank, and the water tank coil absorbs the heat of the water to cool the water in the water tank, so that the temperature of the water tank is lowered to produce ice water, and at this time, the ice cubes on the ice-making column and the ice water in the water tank are running at the same time;

[0056] Step S4, then, after working for a period of time and the water in the water tank cools down, the temperature sensor detects again whether the water temperature in the water tank is lower than the set temperature value T1;

[0057] At the same time, when the temperature sensor detects in step S2 that the water temperature in the water tank is lower than the set temperature value T1+3°C, further detect whether the water temperature in the water tank is lower than the set temperature value T1;

[0058] Step S5, when the water temperature in the water tank is greater than the set temperature T1, the port a of the three-way valve continues to be connected with the port b, the ice cubes on the ice-making column and the ice-making water in the water tank are operated simultaneously, and the refrigerant flows through the water tank coil and then flows back to the compressor. This operation mode can increase the ice-making speed and the fullness of the ice particles produced due to the pre-cooling of the water;

[0059] Step S6, when the water temperature in the water tank is not greater than the set temperature T1, since the ice water produced in the water tank meets the set temperature T1 requirement, the port a of the three-way valve is controlled to be connected with the port c, the refrigerant does not flow through the water tank coil, the ice water production at the water tank is stopped, and the refrigerant directly flows back to the compressor at the three-way valve;

[0060] Step S7, when de-icing is in progress, Figure 6 , Figure 7 and Fig. 9 As shown,

[0061] The high-temperature exhaust gas generated by the compressor does not pass through the condenser, but directly enters the evaporator after passing through the bypass valve. The high-temperature gas increases the temperature of the ice-making column connected to the evaporator, thereby melting the inner layer of the ice-making column for making ice cubes, and directly separates from the ice-making column to make ice cubes;

[0062] Step S8, then, the temperature sensor detects whether the water temperature in the water tank is greater than the set temperature T1;

[0063] Step S9, when the water temperature in the water tank is greater than the set temperature T1, the port a of the three-way valve is connected to the port b, and the refrigerant passing through the evaporator flows through the water tank coil in the water tank, and the water tank coil absorbs the heat of the water to cool the water in the water tank, thereby reducing the temperature of the water tank and producing ice water;

[0064] Step S10, when the water temperature in the water tank is not greater than the set temperature T1, port a of the three-way valve is connected to port c, and the refrigerant does not flow through the water tank coil, but directly flows back to the compressor at the three-way valve.

[0065] Compared with the existing method of defrosting ice cubes on ice-making columns by using a heating device, this control method has a bypass pipeline connected through the corresponding pipeline bypass of the condenser and the capillary tube, so that the refrigerant discharged from the compressor can be directly passed to the evaporator. Before the discharged refrigerant returns to the suction port of the compressor, the switching of the three-way valve port a, port b and port c can be controlled according to the water temperature in the water tank. The refrigerant absorbs the heat of the water through the water tank coil, and the water in the water tank is pre-cooled. Not only does it make the exhaust temperature higher, but it also allows the ice-making column to be heated and defrosted faster, effectively shortening the defrosting time.

[0066] In this embodiment, since the b port of the three-way valve 10 connected to the evaporator 5 is connected to the water tank coil for cooling the stored water arranged in the water tank at the bottom side of the ice making body 3 through a pipeline, the water can be cooled in advance before being pumped into the water box 11 to make ice, so as to achieve the purpose of making ice water. In addition to the basic ice making function, the ice making equipment also has an ice water making function, and the corresponding ice maker can directly output ice cubes and ice water.

[0067] The above-described embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes made based on the shape, structure and principle of the present invention should be included in the protection scope of the present invention.

The high-temperature gas increases the temperature of the ice-making column connected to the evaporator, thereby melting the inner layer of the ice-making column for making ice cubes, and directly separates from the ice-making column to make ice cubes; Step S8, then, the temperature sensor detects whether the water temperature in the water tank is greater than the set temperature T1; Step S9, when the water temperature in the water tank is greater than the set temperature T1, the port a of the three-way valve is connected to the port b, and the refrigerant passing through the evaporator flows through the water tank coil in the water tank, and the water tank coil absorbs the heat of the water to cool the water in the water tank, thereby reducing the temperature of the water tank and producing ice water; Step S10, when the water temperature in the water tank is not greater than the set temperature T1, port a of the three-way valve is connected to port c, and the refrigerant does not flow through the water tank coil, but directly flows back to the compressor at the three-way valve.
