Description

Technical Field

[0001] The present invention belongs to the technical field of liquid treatment, and in particular, relates to a liquid treatment device and a control method thereof, a control device and a readable storage medium. Background Art

[0002] In the prior art, liquid heating devices are generally used to generate steam or heat liquid. During use, scale is easily generated in the pipes of the liquid heating devices. The scale usually adheres to the inner wall of the pipes and is difficult to clean. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a liquid processing device.

[0005] A second aspect of the present invention provides a method for controlling a liquid processing device.

[0006] A third aspect of the present invention provides a control device for a liquid processing device.

[0007] A fourth aspect of the present invention provides a liquid processing device.

[0008] A fifth aspect of the present invention provides a liquid processing device.

[0009] A sixth aspect of the present invention provides a readable storage medium.

[0010] In view of this, according to a first aspect of the present invention, a liquid processing device is proposed, comprising: an infusion component; a heating device, the heating device comprising a heating pipeline and a heating element, the heating pipeline being connected to the infusion component, and the heating element being used to heat the liquid flowing through the heating pipeline; and a refrigeration component connected to the heating pipeline for refrigerating the heating pipeline.

[0011] The liquid handling device provided by the present invention includes an infusion assembly, a heating device, and a refrigeration assembly. The heating device includes a heating pipeline and a heating element. The heating pipeline is connected to the infusion assembly. The infusion assembly can transport liquid into the heating pipeline, and the heating element operates to heat the liquid in the heating pipeline. During the heating operation of the liquid handling device, the infusion assembly operates to transport external liquid into the heating device. After the liquid enters the heating device, it flows within the heating pipeline. The heating element is powered on and operates to heat the heating pipeline. The heat is then transferred through the heating pipeline to the liquid in the heating pipeline, thereby heating the liquid.

[0012] In some embodiments, the heating device is a channel-type heating device for use in a steamer, wherein the heating element is an electric heating element. Upon receiving a start command, the heating device controls the electric heating element to heat the heating pipe. When the heating pipe reaches a preset temperature, the device controls the infusion assembly to deliver water into the heating pipe. The water enters the high-temperature heating pipe and is atomized, and the atomized water vapor is discharged from the heating device.

[0013] During the use of the heating device, scale is easily formed on the inner wall of the heating pipeline. When the heating device stops running, the scale in the heating pipeline can be removed by controlling the operation of the refrigeration component. Specifically, in the process of removing scale, the heating element is first controlled to heat the heating pipeline, and the refrigeration component is controlled to cool the heating pipeline. Since the thermal expansion and contraction coefficients of the heating pipeline and the scale on the pipeline wall are different, the scale on the pipeline wall of the heating pipeline is affected by the thermal expansion and contraction of the objects, causing it to fall off. After the scale falls off, the infusion component is controlled to supply water to the heating device. The water flowing through the heating pipeline can flush the scale out of the heating pipeline, thereby preventing the scale from being discharged from the device along with the heated liquid during normal use of the liquid treatment device, affecting the user experience.

[0014] The present invention incorporates a refrigeration assembly in the liquid handling device for cooling the heating pipeline in the heating device. By alternately heating and cooling the heating pipeline, scale in the heating pipeline can be removed, and then flushed away via the infusion assembly. The refrigeration assembly in the liquid handling device eliminates the need to heat the heating pipeline to excessively high temperatures, ensuring a large temperature differential between hot and cold in the heating pipeline. While achieving the goal of removing scale from the heating pipeline, it also avoids the problem of pipeline aging and damage due to excessively high temperatures.

[0015] It is worth mentioning that in order to improve the descaling effect of the heating device, the steps of heating, cooling and water supplying the heating pipeline can be selected in a cycle.

[0016] In some embodiments, the heating device is selected as a flow channel heating device, the heating element is selected as an electric heating element, and the number of cycles is set to two. The electric heating element is controlled to heat the heating line to 100°C, the refrigeration component is controlled to cool the heating line to -5°C, and the infusion component is controlled to supply water to the heating line to flush out the scale that has fallen off the heating line. The electric heating element is controlled to heat the heating line to 100°C again, the refrigeration component is controlled to cool the heating line to -5°C, and the infusion component is controlled to supply water to the heating line to flush out the scale that has fallen off the heating line.

[0017] In these embodiments, the heating pipeline is heated and cooled multiple times to ensure that most of the scale on the heating pipeline is removed. Between the multiple cooling and heating cycles, the infusion assembly is used to remove the scale from the heating pipeline, thereby achieving the effect of timely removal of the scale and preventing the heating pipeline from being clogged due to excessive scale.

[0018] In addition, the liquid treatment device in the above technical solution provided by the present invention may also have the following additional technical features:

[0019] In one possible design, the refrigeration component includes: a first heat exchange device, connected to the heating pipeline, and capable of storing refrigerant; a first refrigeration device, connected to the first heat exchange device, and used to cool the refrigerant in the heat exchange device.

[0020] In this design, the refrigeration assembly includes a first heat exchanger and a first refrigeration unit. The first heat exchanger is connected to the heating pipeline and stores refrigerant. The first heat exchanger is in communication with the first refrigeration unit, and the first refrigeration unit is capable of cooling the refrigerant in the first heat exchanger. The refrigerant stored in the first heat exchanger is used to exchange heat with the heating pipeline. After the first refrigeration unit cools the refrigerant, the heating pipeline is cooled by heat exchange between the first heat exchanger and the heating pipeline.

[0021] In some embodiments, the method for removing scale from the heating pipe in the heating device using the refrigeration component of the design includes: first controlling the operation of the heating element, continuously detecting the temperature value of the heating pipe through the temperature detection device, and when it is detected that the temperature value of the heating pipe rises to a first set temperature, controlling the first refrigeration device to cool the refrigerant in the first heat exchange device, the refrigerant in the first heat exchange device exchanges heat with the heating pipe, thereby cooling the heating pipe, and the refrigerant in the first heat exchange device drops to a second set temperature under the action of the first refrigeration device. The temperature detection device continuously detects the temperature value of the heating pipe, and when it is detected that the temperature value of the heating pipe reaches a third set temperature, controlling the infusion component to deliver liquid into the heating pipe to flush the scale detached from the heating pipe out of the heating pipe.

[0022] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C. By heating the heating circuit to the first set temperature and the refrigerant in the refrigeration component drops to the second set temperature, it can be ensured that during the descaling process, there is a large temperature difference in the temperature value of the heating circuit, which ensures the descaling effect on the heating circuit. The range of the first set temperature is close to the operating temperature of the heating device, which avoids aging and damage caused by excessive temperature of the heating circuit and the heating element. The range of the third set temperature is between the second set temperature and the first set temperature.

[0023] In one possible design, the refrigeration component includes: a second heat exchange device, connected to the heating pipeline; a refrigerant pipeline, the refrigerant pipeline is connected to the heat exchange device; a second refrigeration device, connected to the refrigerant pipeline, the refrigeration device can store refrigerant and can cool the refrigerant; a first pump body, arranged in the refrigerant pipeline, for inputting the refrigerant in the second refrigeration device into the second heat exchange device.

[0024] In this design, the refrigeration assembly includes a second heat exchange device, a second refrigeration device, and a first pump body. The second refrigeration device can not only cool the refrigerant, but also store the refrigerant. The second heat exchange device is connected to the heating pipeline, and the second heat exchange device can exchange heat with the heating pipeline, thereby cooling and cooling the heating pipeline. The refrigerant pipeline is arranged between the second heat exchange device and the second refrigeration device, and the operation of the first pump body can pump the refrigerant in the second refrigeration device into the second heat exchange device. During the descaling process of the heating pipeline, the second refrigeration device can be controlled to operate first, and the operation of the second refrigeration device can cool and cool the refrigerant stored in the second refrigeration device. The cooled and cooled refrigerant is temporarily stored in the second device. At this time, the heating element is controlled to operate to heat the heating pipeline. After the heating pipeline completes the heating step, the first pump body is controlled to operate to pump the refrigerant in the second refrigeration device into the second heat exchange device, so that the second heat exchange device can exchange heat with the heating pipeline.

[0025] In some embodiments, during the descaling process of the heating pipeline, before the step of controlling the operation of the heating element, the second refrigeration device is operated to cool the refrigerant stored in the second refrigeration device so that the refrigerant temperature drops to a second set temperature.

[0026] In these embodiments, before the heating element heats the heating pipeline, the refrigerant used to cool the heating pipeline is cooled, so that after the heating pipeline is heated to the first set temperature, the refrigerant with a lower temperature is directly transported to the second heat exchange device, so that the second heat exchange device can quickly cool the heating pipeline. After the temperature of the heating pipeline rises, there is no need to reserve cooling time for the refrigerant, thereby improving the efficiency of descaling the heating pipeline.

[0027] In some embodiments, during the descaling process of the heating pipeline, the step of cooling the heating pipeline by the refrigeration component includes: operating the first pump body to transport the refrigerant in the second refrigeration device to the second heat exchange device.

[0028] In these embodiments, before the heating pipeline is heated, the temperature of the refrigerant in the second refrigeration device has dropped to the second set temperature. During the cooling process of the heating pipeline, the refrigerant that has dropped to the second set temperature is directly transported to the second heat exchange device, thereby achieving a rapid drop in the temperature of the heating pipeline and improving the descaling effect on the heating pipeline.

[0029] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0030] In one possible design, the refrigeration assembly includes: a liquid inlet pipeline for supplying liquid to the infusion assembly; a third refrigeration device for cooling the refrigerant; a reversing valve, wherein the first end of the reversing valve is connected to the infusion assembly, the second end of the reversing valve is connected to the third refrigeration device, and the third end of the reversing valve is connected to the liquid inlet pipeline.

[0031] In this design, the refrigeration assembly includes a liquid inlet line, a reversing valve, and a third refrigeration unit. After cooling the refrigerant, the third refrigeration unit delivers the refrigerant to the infusion assembly, which then delivers the refrigerant to the heating line, thereby cooling the heating line. By directly introducing the refrigerant into the heating line to be cooled, the temperature of the heating line can be quickly reduced, improving the efficiency of cooling and descaling the heating line.

[0032] In some embodiments, the third refrigeration device can not only cool the refrigerant, but also store the refrigerant. Before the heating pipeline is heated and heated, the third refrigeration device is controlled to cool the refrigerant stored inside. At this time, the reversing valve connects the liquid inlet pipeline with the infusion component, that is, the third refrigeration device is not connected to the heating pipeline, ensuring that the refrigerant in the third refrigeration device will not flow into the heating pipeline. When the heating pipeline is heated and heated to the first set temperature, the reversing valve is controlled to operate, connecting the third refrigeration device with the infusion component, and the refrigerant in the third refrigeration device flows into the heating pipeline to cool the heating pipeline. Since the refrigerant has reached the second set temperature before the heating pipeline reaches the first set temperature, the refrigerant that has dropped to the second set temperature is directly transported to the heating pipeline, so that the temperature of the heating pipeline is rapidly reduced, thereby improving the descaling effect on the heating pipeline.

[0033] In other embodiments, the heating element is first controlled to heat the heating line. During the heating process, the reversing valve connects the liquid inlet line to the infusion assembly, that is, the third refrigeration unit is disconnected from the heating line, ensuring that the refrigerant in the third refrigeration unit does not flow into the heating line. When the heating line is heated to a first set temperature, the reversing valve is controlled to operate, connecting the third refrigeration unit to the infusion assembly, and the third refrigeration unit begins to operate to cool the refrigerant. When the refrigerant drops to a second temperature, the infusion assembly is controlled to deliver the refrigerant to the heating line to cool the heating line.

[0034] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0035] In any of the above possible designs, the refrigerant can be selected as a refrigerant such as brine to ensure that the refrigerant does not solidify when it reaches the second set temperature, ensure the fluidity of the refrigerant, and avoid refrigerant blockage that causes cooling failure of the heating pipeline.

[0036] Specifically, the refrigerant is selected as edible salt water, which prevents the refrigerant from contaminating the heating pipeline when the refrigerant flows through the heating pipeline.

[0037] In one possible design, the infusion assembly includes: an infusion pipeline, connected to the heating pipeline; a second pump body, arranged in the infusion pipeline, used to pump the liquid in the infusion pipeline to the heating pipeline; and a liquid outlet pipeline, connected to the heating pipeline, used to discharge the liquid in the heating pipeline.

[0038] In this design, the infusion assembly includes an infusion line, an outlet line, and a second pump. Both the infusion line and the outlet line are connected to the heating line in the heating device. The second pump is controlled to pump the liquid in the infusion line into the heating line. As the second pump continues to operate, the liquid in the heating line is discharged through the outlet line. By incorporating the infusion assembly into the liquid handling device, the fluidity of the liquid in the heating line is maintained, ensuring efficient heating of the liquid by the liquid handling device.

[0039] According to a second aspect of the present invention, a control method for a liquid processing device is proposed. The liquid processing device includes an infusion component, a heating device and a refrigeration component. The heating device includes a heating pipeline and a heating element. The heating pipeline is connected to the infusion component, and the refrigeration component is connected to the heating pipeline. The method includes: controlling the operation of the heating element; based on the heating pipeline reaching a first set temperature, controlling the refrigeration component to cool the heating pipeline; and controlling the infusion component to inject liquid into the heating pipeline.

[0040] The control method provided by the present invention is used to control a liquid handling device. The liquid handling device includes an infusion assembly, a heating device, and a refrigeration assembly. The heating device includes a heating pipeline and a heating element. The heating pipeline is connected to the infusion assembly. The infusion assembly can transport liquid into the heating pipeline. The operation of the heating element can heat the liquid in the heating pipeline. During the heating operation of the liquid handling device, the infusion assembly operates to transport external liquid into the heating device. After the liquid enters the heating device, it flows in the heating pipeline. The heating element is powered on and operates to heat the heating pipeline. The heat is transferred through the heating pipeline to the liquid in the heating pipeline, thereby heating the liquid.

[0041] In some embodiments, the heating device is a channel-type heating device for use in a steamer, wherein the heating element is an electric heating element. Upon receiving a start command, the heating device controls the electric heating element to heat the heating pipe. When the heating pipe reaches a preset temperature, the device controls the infusion assembly to deliver water into the heating pipe. The water enters the high-temperature heating pipe and is atomized, and the atomized water vapor is discharged from the heating device.

[0042] During the use of the heating device, scale is easily formed on the inner wall of the heating pipeline. When the heating device stops running, the scale in the heating pipeline can be removed by controlling the operation of the refrigeration component. Specifically, in the process of removing scale, the heating element is first controlled to heat the heating pipeline. When the temperature of the heating pipeline rises to the first set temperature, the refrigeration component is controlled to cool the heating pipeline. Since the thermal expansion and contraction coefficients of the heating pipeline and the scale on the pipeline wall are different, the scale on the pipeline wall of the heating pipeline is affected by the thermal expansion and contraction of the objects, causing it to fall off. After the scale falls off, the infusion component is controlled to supply water to the heating device. The water flowing through the heating pipeline can flush the scale out of the heating pipeline, thereby preventing the scale from being discharged from the device along with the heated liquid during normal use of the liquid treatment device, affecting the user experience.

[0043] The present invention provides a refrigeration component for cooling the heating pipeline in the heating device in the liquid treatment device. By first heating the heating pipeline and then cooling the heating pipeline at a higher temperature, the heating pipeline undergoes a wide temperature change in a short period of time, thereby causing scale in the heating pipeline to fall off. The scale in the heating pipeline is then flushed away by the infusion component. Since the refrigeration component is provided in the liquid treatment device, it is not necessary to heat the heating pipeline to an excessively high temperature, and a large temperature difference between hot and cold in the heating pipeline can be ensured. Under the premise of achieving the removal of scale in the heating pipeline, the problem of pipeline aging and damage caused by excessively high temperature in the heating pipeline is avoided.

[0044] In addition, the control method of the liquid treatment device in the above technical solution provided by the present invention may also have the following additional technical features:

[0045] In one possible design, the refrigeration component includes a first heat exchange device and a first refrigeration device, and controlling the refrigeration component to cool the heating element specifically includes: controlling the operation of the first refrigeration device so that the refrigerant in the first heat exchange device reaches a second set temperature.

[0046] In this design, the refrigeration assembly includes a first heat exchanger and a first refrigeration unit. The first heat exchanger is connected to the heating pipeline and stores refrigerant. The first heat exchanger is in communication with the first refrigeration unit, and the first refrigeration unit is capable of cooling the refrigerant in the first heat exchanger. The refrigerant stored in the first heat exchanger is used to exchange heat with the heating pipeline. After the first refrigeration unit cools the refrigerant, the heating pipeline is cooled by heat exchange between the first heat exchanger and the heating pipeline.

[0047] First, the heating element is controlled to operate, and the temperature detection device continuously detects the temperature of the heating pipeline. When it is detected that the temperature of the heating pipeline has risen to the first set temperature, the first refrigeration device is controlled to cool the refrigerant in the first heat exchange device. The refrigerant in the first heat exchange device exchanges heat with the heating pipeline, thereby cooling the heating pipeline. Under the action of the first refrigeration device, the refrigerant in the first heat exchange device drops to the second set temperature. The temperature detection device continuously detects the temperature of the heating pipeline. When it is detected that the temperature of the heating pipeline has reached the third set temperature, the infusion component is controlled to deliver liquid into the heating pipeline to flush out the scale that has fallen off the heating pipeline.

[0048] It can be understood that the value range of the first set temperature is 100℃ to 120℃, the value range of the second set temperature is -10℃ to -3℃, and the value range of the third set temperature is -5℃ to 0℃. By heating the heating pipeline to the first set temperature and the refrigerant in the refrigeration component drops to the second set temperature, it can be ensured that during the descaling process. There is a large temperature difference in the temperature value of the heating pipeline, which ensures the descaling effect on the heating pipeline. The value range of the first set temperature is close to the operating temperature of the heating device, which avoids aging and damage caused by excessive temperature of the heating pipeline and heating element. The value range of the third set temperature is between the second set temperature and the first set temperature.

[0049] In one possible design, the refrigeration component includes a second heat exchange device, a refrigerant pipeline, a second refrigeration device and a first pump body. The second heat exchange device is connected to the heating pipeline. The second refrigeration device is connected to the second heat exchange device through the refrigerant pipeline. The first pump body is arranged in the refrigerant pipeline. Before controlling the operation of the heating element, it also includes: controlling the operation of the second refrigeration device until the refrigerant in the second refrigeration device reaches the second set temperature.

[0050] In this design, the refrigeration assembly includes a second heat exchange device, a second refrigeration device, and a first pump body. The second refrigeration device can not only cool the refrigerant, but also store the refrigerant. The second heat exchange device is connected to the heating pipeline, and the second heat exchange device can exchange heat with the heating pipeline, thereby cooling and cooling the heating pipeline. The refrigerant pipeline is arranged between the second heat exchange device and the second refrigeration device, and the operation of the first pump body can pump the refrigerant in the second refrigeration device into the second heat exchange device. During the descaling process of the heating pipeline, the second refrigeration device can be controlled to operate first, and the operation of the second refrigeration device can cool and cool the refrigerant stored in the second refrigeration device. The cooled and cooled refrigerant is temporarily stored in the second device. At this time, the heating element is controlled to operate to heat the heating pipeline. After the heating pipeline completes the heating step, the first pump body is controlled to operate to pump the refrigerant in the second refrigeration device into the second heat exchange device, so that the second heat exchange device can exchange heat with the heating pipeline.

[0051] During the descaling process of the heating pipeline, before the step of controlling the operation of the heating element, the second refrigeration device is operated to cool the refrigerant stored in the second refrigeration device, so that the temperature of the refrigerant drops to the second set temperature. Before the heating element heats the heating pipeline, the refrigerant used to cool the heating pipeline is cooled. After the heating pipeline is heated to the first set temperature, the lower temperature refrigerant is directly transported to the second heat exchange device, so that the second heat exchange device can quickly cool the heating pipeline. After the heating pipeline temperature rises, there is no need to reserve cooling time for the refrigerant, thereby improving the efficiency of descaling the heating pipeline.

[0052] In one possible design, controlling the refrigeration component to cool the heating element specifically includes: controlling the operation of the first pump body to allow the refrigerant to enter the second heat exchange device.

[0053] In this design, during the descaling process of the heating pipeline, when the temperature of the heating pipeline rises to the first temperature, the first pump body is operated to transport the refrigerant in the second refrigeration unit to the second heat exchange device. Before the heating pipeline is heated up, the refrigerant temperature in the second refrigeration unit has already dropped to the second set temperature. During the cooling process of the heating pipeline, the refrigerant, which has dropped to the second set temperature, is directly transported to the second heat exchange device, achieving a rapid decrease in the temperature of the heating pipeline and improving the descaling effect on the heating pipeline.

[0054] It can be understood that the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0055] In one possible design, the refrigeration component includes a liquid inlet pipeline, a third refrigeration device and a reversing valve. The third refrigeration device is used to cool the refrigerant. The first end of the reversing valve is connected to the infusion component, the second end of the reversing valve is connected to the third refrigeration device, and the third end of the reversing valve is connected to the liquid inlet pipeline. Controlling the refrigeration component to cool the heating element specifically includes: controlling the operation of the third refrigeration device to make the refrigerant in the third refrigeration device reach the second set temperature; controlling the second end of the reversing valve to be connected to the first end, and controlling the operation of the infusion component to allow the refrigerant to enter the heating pipeline.

[0056] In this design, the refrigeration assembly includes a liquid inlet line, a reversing valve, and a third refrigeration unit. After cooling the refrigerant, the third refrigeration unit delivers the refrigerant to the infusion assembly, which then delivers the refrigerant to the heating line, thereby cooling the heating line. By directly introducing the refrigerant into the heating line to be cooled, the temperature of the heating line can be quickly reduced, improving the efficiency of cooling and descaling the heating line.

[0057] In some embodiments, the third refrigeration device can not only cool the refrigerant, but also store the refrigerant. Before the heating pipeline is heated and heated, the third refrigeration device is controlled to cool the refrigerant stored inside. At this time, the reversing valve connects the liquid inlet pipeline with the infusion component, that is, the third refrigeration device is not connected to the heating pipeline, ensuring that the refrigerant in the third refrigeration device will not flow into the heating pipeline. When the heating pipeline is heated and heated to the first set temperature, the reversing valve is controlled to operate, connecting the third refrigeration device with the infusion component, and the refrigerant in the third refrigeration device flows into the heating pipeline to cool the heating pipeline. Since the refrigerant has reached the second set temperature before the heating pipeline reaches the first set temperature, the refrigerant that has dropped to the second set temperature is directly transported to the heating pipeline, so that the temperature of the heating pipeline is rapidly reduced, thereby improving the descaling effect on the heating pipeline.

[0058] In other embodiments, the heating element is first controlled to heat the heating line. During the heating process, the reversing valve connects the liquid inlet line to the infusion assembly, that is, the third refrigeration unit is disconnected from the heating line, ensuring that the refrigerant in the third refrigeration unit does not flow into the heating line. When the heating line is heated to a first set temperature, the reversing valve is controlled to operate, connecting the third refrigeration unit to the infusion assembly, and the third refrigeration unit begins to operate to cool the refrigerant. When the refrigerant drops to a second temperature, the infusion assembly is controlled to deliver the refrigerant to the heating line to cool the heating line.

[0059] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0060] In any of the above possible designs, the refrigerant can be selected as a refrigerant such as brine to ensure that the refrigerant does not solidify when it reaches the second set temperature, ensure the fluidity of the refrigerant, and avoid refrigerant blockage that causes cooling failure of the heating pipeline.

[0061] Specifically, the refrigerant is selected as edible salt water, which prevents the refrigerant from contaminating the heating pipeline when the refrigerant flows through the heating pipeline.

[0062] In one possible design, the infusion component includes: an infusion pipeline, a second pump body and an outlet pipeline, the infusion pipeline is connected to the heating pipeline, the second pump body is arranged on the infusion pipeline, the outlet pipeline is connected to the heating pipeline, and the infusion component is controlled to inject liquid into the heating pipeline, including: based on the heating pipeline reaching a third set temperature, controlling the second pump body to operate to infuse liquid into the heating pipeline; the third set temperature is lower than the first set temperature.

[0063] In this design, the infusion assembly includes an infusion line, an outlet line, and a second pump. Both the infusion line and the outlet line are connected to the heating line in the heating device. The second pump is controlled to pump the liquid in the infusion line into the heating line. As the second pump continues to operate, the liquid in the heating line is discharged through the outlet line. By incorporating the infusion assembly into the liquid handling device, the fluidity of the liquid in the heating line is maintained, ensuring efficient heating of the liquid by the liquid handling device.

[0064] During the process of the refrigeration component cooling the heating pipeline, the temperature value of the heating pipeline is continuously detected. When it is detected that the temperature value of the heating pipeline drops to the third set temperature, it is determined that most of the scale in the heating pipeline has fallen off at this time, and the second pump body is controlled to operate to input liquid from an external liquid source into the heating pipeline to flush and clean the scale in the heating pipeline, so as to avoid the scale being discharged from the device along with the heated liquid during normal use of the liquid treatment device, affecting the user experience.

[0065] In a possible design, after controlling the infusion component to inject liquid into the heating pipeline, it also includes: obtaining the number of operations of the infusion component; and returning to the step of controlling the operation of the heating element based on the number of operations not reaching the set number.

[0066] In this design, to improve the effectiveness of descaling the heating device, the heating, cooling, and water delivery steps can be cycled through the heating pipeline multiple times. Upon receiving the descaling command, the liquid handling device determines the number of descaling steps required, i.e., the set number of times the infusion assembly has been run. If the infusion assembly has not delivered water to the heating pipeline for the set number of flushes, the system returns to heating the heating pipeline with the heating element. Upon detecting that the set number of flushes has been reached, the descaling process for the liquid handling device is complete, and the device is controlled to stop.

[0067] According to a third aspect of the present invention, a control device for a liquid processing device is proposed. The liquid processing device includes an infusion component, a heating device and a refrigeration component. The heating device includes a heating pipeline and a heating element.

The heating element can heat the liquid in the heating pipeline when it is in operation. During the heating operation of the liquid handling device, the infusion component operates to transport external liquid into the heating device. After the liquid enters the heating device, it flows in the heating pipeline. The heating element is powered on and operates to heat the heating pipeline. The heat is then transferred through the heating pipeline to the liquid in the heating pipeline, thereby heating the liquid.

The water enters the high-temperature heating pipe and is atomized, and the atomized water vapor is discharged from the heating device.

[0070] During the use of the heating device, scale is easily formed on the inner wall of the heating pipeline.

The electric heating element is controlled to heat the heating line to 100°C again, the refrigeration component is controlled to cool the heating line to -5°C, and the infusion component is controlled to supply water to the heating line to flush out the scale that has fallen off the heating line.

[0074] In these embodiments, the heating pipeline is heated and cooled multiple times to ensure that most of the scale on the heating pipeline is removed. Between the multiple cooling and heating cycles, the infusion assembly is used to remove the scale from the heating pipeline, thereby achieving the effect of timely removal of the scale and preventing the heating pipeline from being clogged due to excessive scale.

DETAILED DESCRIPTION

[0093] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0094] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0095] Refer to the following Figures 1 to 11 A liquid processing device, a method for controlling a liquid processing device, a control device for a liquid processing device, and a readable storage medium according to some embodiments of the present invention are described.

[0096] Example 1:

[0097] like Figure 1 As shown, a first embodiment of the present invention provides a liquid processing device 100 , including: an infusion component 120 , a heating device 140 and a refrigeration component 160 .

[0098] The heating device 140 includes a heating element 144 and a heating line 142. The heating line 142 is connected to the infusion assembly 120. The heating element 144 can heat the liquid flowing through the heating line 142.

[0099] The refrigeration component 160 is connected to the heating pipeline 142 , and the refrigeration component 160 can cool the heating pipeline 142 .

[0100] The liquid treatment device 100 provided in an embodiment of the present application includes an infusion component 120, a heating device 140, and a refrigeration component 160. The heating device 140 includes a heating line 142 and a heating element 144. The heating line 142 is connected to the infusion component 120. The infusion component 120 can transport liquid into the heating line 142. The heating element 144 can heat the liquid in the heating line 142 when it is in operation. During the heating operation of the liquid treatment device 100, the infusion component 120 operates to transport external liquid into the heating device 140. After the liquid enters the heating device 140, it flows in the heating line 142. The heating element 144 is powered on and operates to heat the heating line 142. The heat is transferred to the liquid in the heating line 142 through the heating line 142, thereby heating the liquid.

[0101] In some embodiments, heating device 140 is a channel-type heating device 140 for use in a steamer, wherein heating element 144 is an electric heating element. Upon receiving a start instruction, heating device 140 controls the electric heating element to heat heating pipe 142. When heating pipe 142 reaches a preset temperature, infusion assembly 120 is controlled to deliver water into heating pipe 142. The water enters the high-temperature heating pipe 142 and is atomized. The atomized water vapor is then discharged from heating device 140.

[0102] During the use of the heating device 140, scale is easily formed on the inner wall of the heating pipe 142. When the heating device 140 stops running, the scale in the heating pipe 142 can be removed by controlling the operation of the refrigeration component 160. Specifically, in the process of removing scale, the heating element 144 is first controlled to heat the heating pipe 142, and the refrigeration component 160 is controlled to cool the heating pipe 142. Since the thermal expansion and contraction coefficients of the heating pipe 142 and the scale on the pipe wall are different, the scale on the pipe wall of the heating pipe 142 is affected by the thermal expansion and contraction of the objects, causing the scale to fall off. After the scale falls off, the infusion component 120 is controlled to supply water to the heating device 140. The water flowing through the heating pipe 142 can flush the scale out of the heating pipe 142, thereby preventing the scale from being discharged from the device along with the heated liquid during normal use of the liquid treatment device 100, affecting the user's experience.

[0103] The present invention provides a refrigeration assembly 160 in the liquid treatment device 100 for cooling the heating pipe 142 in the heating device 140. By alternately heating and cooling the heating pipe 142, scale in the heating pipe 142 can be removed, and then flushed away via the infusion assembly 120. The provision of the refrigeration assembly 160 in the liquid treatment device 100 eliminates the need to heat the heating pipe 142 to excessively high temperatures, ensuring a large temperature difference between hot and cold in the heating pipe 142. While achieving the goal of removing scale from the heating pipe 142, the problem of pipe aging and damage due to excessively high temperatures in the heating pipe 142 is avoided.

[0104] It is worth noting that, in order to improve the descaling effect of the heating device 140 , the steps of heating, cooling and water supplying the heating pipe 142 can be selected to be cyclically performed.

[0105] In some embodiments, the heating device 140 is selected as a flow channel heating device 140, the heating element 144 is selected as an electric heating element, and the number of cycles is set to two. The electric heating element is controlled to heat the heating line 142 to 100°C, the refrigeration component 160 is controlled to cool the heating line 142 to -5°C, and the infusion component 120 is controlled to supply water to the heating line 142 to flush the scale detached from the heating line 142 out of the heating line 142. The electric heating element is controlled to heat the heating line 142 to 100°C again, the refrigeration component 160 is controlled to cool the heating line 142 to -5°C, and the infusion component 120 is controlled to supply water to the heating line 142 to flush the scale detached from the heating line 142 out of the heating line 142.

[0106] In these embodiments, the heating line 142 is heated and cooled multiple times to ensure that most of the scale on the heating line 142 is removed. Between the multiple cooling and heating cycles, the infusion assembly 120 removes the scale from the heating line 142, thereby promptly removing the scale and preventing the heating line 142 from being clogged due to excessive scale.

[0107] like Figure 1 As shown, in any of the above embodiments, the refrigeration assembly 160 includes: a first heat exchange device 162 and a first refrigeration device 161 .

[0108] The first heat exchange device 162 is connected to the heating pipeline 142. The first heat exchange device 162 can store refrigerant. The refrigerant in the first heat exchange device 162 can exchange heat with the heating pipeline 142 to cool the heating pipeline 142.

[0109] The first refrigeration device 161 is connected to the first heat exchange device 162 , and the first refrigeration device 161 can cool and reduce the temperature of the refrigerant stored in the first heat exchange device 162 .

[0110] In this embodiment, refrigeration assembly 160 includes a first heat exchanger 162 and a first refrigeration unit 161. First heat exchanger 162 is connected to heating line 142 and stores refrigerant. First heat exchanger 162 is in communication with first refrigeration unit 161, and first refrigeration unit 161 is capable of cooling the refrigerant in first heat exchanger 162. The refrigerant stored in first heat exchanger 162 is used to exchange heat with heating line 142. After first refrigeration unit 161 cools the refrigerant, the heating line 142 is cooled by heat exchange between first heat exchanger 162 and heating line 142.

[0111] In some embodiments, the method for removing scale from the heating pipe 142 in the heating device 140 using the refrigeration assembly 160 of this design includes: first controlling the operation of the heating element 144, continuously detecting the temperature of the heating pipe 142 through the temperature detection device, and when it is detected that the temperature of the heating pipe 142 has risen to a first set temperature, controlling the first refrigeration device 161 to cool the refrigerant in the first heat exchange device 162, so that the refrigerant in the first heat exchange device 162 exchanges heat with the heating pipe 142, thereby cooling the heating pipe 142, and the refrigerant in the first heat exchange device 162 drops to a second set temperature under the action of the first refrigeration device 161. The temperature detection device continuously detects the temperature of the heating pipe 142, and when it is detected that the temperature of the heating pipe 142 has reached a third set temperature, controlling the infusion assembly 120 to deliver liquid into the heating pipe 142 to flush the scale removed from the heating pipe 142.

[0112] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C. By heating the heating line 142 to the first set temperature and the refrigerant in the refrigeration assembly 160 drops to the second set temperature, it can be ensured that during the descaling process. There is a large temperature difference in the temperature value of the heating line 142, which ensures the descaling effect on the heating line 142. The value range of the first set temperature is close to the operating temperature of the heating device 140, avoiding aging and damage caused by excessive temperature of the heating line 142 and the heating element 144. The value range of the third set temperature is between the second set temperature and the first set temperature.

[0113] like Figure 2 As shown, in any of the above embodiments, the refrigeration assembly 160 includes a second heat exchange device 164 , a first pump body 165 and a second refrigeration device 163 .

[0114] The second refrigeration device 163 is capable of storing and cooling the refrigerant, and the second refrigeration device 163 is connected to the second heat exchange device 164 through a refrigerant pipeline;

[0115] The first pump body 165 is arranged on the refrigerant pipeline and can pump the refrigerant in the second refrigeration device 163 into the second heat exchange device 164;

[0116] The second heat exchange device 164 is in contact with the heating pipeline 142 and can perform heat exchange and temperature reduction on the heating pipeline 142 .

[0117] In this embodiment, the refrigeration assembly 160 includes a second heat exchange device 164, a second refrigeration device 163, and a first pump body 165. The second refrigeration device 163 is capable of not only cooling the refrigerant but also storing the refrigerant. The second heat exchange device 164 is connected to the heating pipeline 142 and can exchange heat with the heating pipeline 142, thereby cooling and cooling the heating pipeline 142. The refrigerant pipeline is arranged between the second heat exchange device 164 and the second refrigeration device 163. When the first pump body 165 is in operation, the refrigerant in the second refrigeration device 163 can be pumped into the second heat exchange device 164. During the descaling process of the heating pipe 142, the second refrigeration device 163 can be controlled to operate first. The operation of the second refrigeration device 163 can cool and cool the refrigerant stored in the second refrigeration device 163. The cooled and cooled refrigerant is temporarily stored in the second device. At this time, the heating element 144 is controlled to operate to heat the heating pipe 142. After the heating pipe 142 completes the heating step, the first pump body 165 is controlled to operate to pump the refrigerant in the second refrigeration device 163 into the second heat exchange device 164, so that the second heat exchange device 164 can exchange heat with the heating pipe 142.

[0118] In some embodiments, during the descaling process of the heating pipe 142 , before the step of controlling the operation of the heating element 144 , the second refrigeration device 163 is operated to cool the refrigerant stored in the second refrigeration device 163 so that the refrigerant temperature drops to the second set temperature.

[0119] In these embodiments, before the heating element 144 heats the heating pipe 142, the refrigerant used to cool the heating pipe 142 is cooled, so that after the heating pipe 142 is heated to the first set temperature, the refrigerant with a lower temperature is directly transported to the second heat exchange device 164, so that the second heat exchange device 164 can quickly cool the heating pipe 142. After the temperature of the heating pipe 142 rises, there is no need to reserve cooling time for the refrigerant, thereby improving the efficiency of descaling the heating pipe 142.

[0120] In some embodiments, during the descaling process of the heating pipe 142 , the step of cooling the heating pipe 142 by the refrigeration assembly 160 includes: the first pump body 165 operates to transport the refrigerant in the second refrigeration device 163 to the second heat exchange device 164 .

[0121] In these embodiments, before the heating pipe 142 is heated, the temperature of the refrigerant in the second refrigeration device 163 has dropped to the second set temperature. During the cooling process of the heating pipe 142, the refrigerant that has dropped to the second set temperature is directly transported to the second heat exchange device 164, thereby achieving a rapid drop in the temperature of the heating pipe 142 and improving the descaling effect of the heating pipe 142.

[0122] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0123] like Figure 3 As shown, in any of the above embodiments, the refrigeration assembly 160 includes a reversing valve 168 , a liquid inlet pipeline 167 and a third refrigeration device 166 .

[0124] The reversing valve 168 includes a first end, a second end, and a third end. The first end is connected to the infusion assembly 120, the second end is connected to the third refrigeration device 166, and the third end is connected to the liquid inlet pipeline 167;

[0125] The third refrigeration device 166 can cool down the refrigerant, and the infusion component 120 can be supplied with liquid through the liquid inlet pipeline 167.

[0126] In this embodiment, the refrigeration assembly 160 includes a liquid inlet line 167, a reversing valve 168, and a third refrigeration unit 166. After cooling the refrigerant, the third refrigeration unit 166 delivers the refrigerant to the infusion assembly 120. Through the infusion assembly 120, the refrigerant is delivered to the heating line 142, thereby cooling the heating line 142. By directly introducing the refrigerant into the heating line 142 to be cooled, the temperature of the heating line 142 can be rapidly reduced, improving the efficiency of cooling and cooling the heating line 142, and thus enhancing the descaling effect of the heating line 142.

[0127] In some embodiments, the third refrigeration unit 166 is capable of not only cooling the refrigerant but also storing it. Before heating the heating line 142, the third refrigeration unit 166 is controlled to cool the refrigerant stored therein. At this time, the reversing valve 168 connects the inlet line 167 to the infusion assembly 120, thereby disconnecting the third refrigeration unit 166 from the heating line 142, thereby preventing the refrigerant in the third refrigeration unit 166 from flowing into the heating line 142. When the heating pipe 142 is heated to the first set temperature, the reversing valve 168 is controlled to operate, and the third refrigeration device 166 is connected to the infusion component 120. The refrigerant in the third refrigeration device 166 flows into the heating pipe 142 to refrigerate the heating pipe 142. Since the refrigerant has reached the second set temperature before the heating pipe 142 reaches the first set temperature, the refrigerant that has dropped to the second set temperature is directly transported to the heating pipe 142, thereby achieving a rapid drop in the temperature of the heating pipe 142 and improving the descaling effect of the heating pipe 142.

[0128] In some other embodiments, the heating element 144 is first controlled to heat the heating line 142. During the heating process, the reversing valve 168 connects the liquid inlet line 167 with the infusion assembly 120, that is, the third refrigeration unit 166 is disconnected from the heating line 142, ensuring that the refrigerant in the third refrigeration unit 166 does not flow into the heating line 142. When the heating line 142 is heated to a first set temperature, the reversing valve 168 is controlled to operate, connecting the third refrigeration unit 166 with the infusion assembly 120. The third refrigeration unit 166 starts to operate to cool the refrigerant. When the refrigerant drops to a second temperature, the infusion assembly 120 is controlled to transport the refrigerant to the heating line 142 to cool the heating line 142.

[0129] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0130] In any of the above embodiments, the refrigerant can be selected as a refrigerant such as brine to ensure that the refrigerant does not solidify when it reaches the second set temperature, ensure the fluidity of the refrigerant, and avoid refrigerant blockage that causes the cooling of the heating pipe 142 to fail.

[0131] Specifically, the refrigerant is selected as edible salt water, and when the refrigerant flows through the heating pipeline 142 , the refrigerant is prevented from contaminating the heating pipeline 142 .

[0132] like Figure 1 、 Figure 2 and Figure 3 As shown, in any of the above embodiments, the infusion assembly 120 includes an infusion line 122 , a liquid outlet line 126 and a second pump body 124 .

[0133] The infusion line 122 and the discharge line 126 are both connected to the heating line 142;

[0134] The second pump body 124 is disposed on the infusion pipeline 122 . When the second pump body 124 is in operation, the liquid enters the heating pipeline 142 through the infusion pipeline 122 and is discharged from the heating pipeline 142 through the liquid outlet pipeline 126 .

[0135] In this embodiment, the infusion assembly 120 includes an infusion line 122, an outlet line 126, and a second pump 124. Both the infusion line 122 and the outlet line 126 are connected to a heating line 142 in the heating device 140. The second pump 124 is controlled to pump the liquid in the infusion line 122 into the heating line 142. As the second pump 124 continues to operate, the liquid that has entered the heating line 142 is discharged through the outlet line 126. By incorporating the infusion assembly 120 into the liquid treatment device 100, the fluidity of the liquid in the heating line 142 is ensured, thereby ensuring the efficient heating of the liquid by the liquid treatment device 100.

[0136] Example 2:

[0137] like Figure 4 As shown, in the first embodiment of the present invention, a control method for a liquid treatment device is provided for controlling the operation of the liquid treatment device, wherein the liquid treatment device includes: an infusion component, a heating device, and a refrigeration component. The heating device includes a heating element and a heating pipeline, the heating pipeline is connected to the infusion component, and the heating element can heat the liquid flowing through the heating pipeline; the refrigeration component is connected to the heating pipeline, and the refrigeration component can cool the heating pipeline. The control method of the liquid treatment device specifically includes:

[0138] Step 402, in response to the descaling instruction, controlling the heating element to start operating;

[0139] Step 404, detecting the temperature of the heating pipe;

[0140] Step 406, determining whether the temperature of the heating pipe has risen to the first set temperature, if so, executing step 408, otherwise, returning to executing step 404;

[0141] Step 408: Control the refrigeration component to operate so as to cool the heating pipe;

[0142] Step 410: Control the infusion component to operate to flush the heating line.

[0143] The control method provided in an embodiment of the present invention is used to control a liquid handling device. The liquid handling device includes an infusion assembly, a heating device, and a refrigeration assembly. The heating device includes a heating pipeline and a heating element. The heating pipeline is connected to the infusion assembly. The infusion assembly can transport liquid into the heating pipeline. The heating element can heat the liquid in the heating pipeline when it is in operation. During the heating operation of the liquid handling device, the infusion assembly operates to transport external liquid into the heating device. After the liquid enters the heating device, it flows in the heating pipeline. The heating element is powered on and operates to heat the heating pipeline. The heat is then transferred through the heating pipeline to the liquid in the heating pipeline, thereby heating the liquid.

[0144] In some embodiments, the heating device is a channel-type heating device for use in a steamer, wherein the heating element is an electric heating element. Upon receiving a start command, the heating device controls the electric heating element to heat the heating pipe. When the heating pipe reaches a preset temperature, the device controls the infusion assembly to deliver water into the heating pipe. The water enters the high-temperature heating pipe and is atomized, and the atomized water vapor is discharged from the heating device.

[0145] During the use of the heating device, scale is easily formed on the inner wall of the heating pipeline. When the heating device stops running, the scale in the heating pipeline can be removed by controlling the operation of the refrigeration component. Specifically, in the process of removing scale, the heating element is first controlled to heat the heating pipeline. When the temperature of the heating pipeline rises to the first set temperature, the refrigeration component is controlled to cool the heating pipeline. Since the thermal expansion and contraction coefficients of the heating pipeline and the scale on the pipeline wall are different, the scale on the pipeline wall of the heating pipeline is affected by the thermal expansion and contraction of the objects, causing it to fall off. After the scale falls off, the infusion component is controlled to supply water to the heating device. The water flowing through the heating pipeline can flush the scale out of the heating pipeline, thereby preventing the scale from being discharged from the device along with the heated liquid during normal use of the liquid treatment device, affecting the user experience.

[0146] The present invention provides a refrigeration component for cooling the heating pipeline in the heating device in the liquid treatment device. By first heating the heating pipeline and then cooling the heating pipeline at a higher temperature, the heating pipeline undergoes a wide temperature change in a short period of time, thereby causing scale in the heating pipeline to fall off. The scale in the heating pipeline is then flushed away by the infusion component. Since the refrigeration component is provided in the liquid treatment device, it is not necessary to heat the heating pipeline to an excessively high temperature, and a large temperature difference between hot and cold in the heating pipeline can be ensured. Under the premise of achieving the removal of scale in the heating pipeline, the problem of pipeline aging and damage caused by excessively high temperature in the heating pipeline is avoided.

[0147] like Figure 5 As shown, in some embodiments, the refrigeration assembly includes: a first heat exchange device and a first refrigeration device.

[0148] The first heat exchange device is connected to the heating pipeline, and the first heat exchange device can store refrigerant. The refrigerant in the first heat exchange device can exchange heat with the heating pipeline to cool the heating pipeline;

[0149] The first refrigeration device is connected to the first heat exchange device, and the first refrigeration device can cool and reduce the temperature of the refrigerant stored in the first heat exchange device.

[0150] A control method for a liquid processing device, specifically comprising:

[0151] Step 502, in response to the descaling instruction, controlling the heating element to start operation;

[0152] Step 504, detecting the temperature of the heating pipeline;

[0153] Step 506, determining whether the temperature of the heating pipe has risen to the first set temperature, if so, executing step 508, otherwise, returning to executing step 504;

[0154] Step 508: Control the first refrigeration device to cool the refrigerant in the first heat exchange device;

[0155] Step 510, determining whether the refrigerant in the first heat exchange device has dropped to the second set temperature. If yes, proceed to step 512; otherwise, return to step 508;

[0156] Step 512: Control the infusion component to operate to flush the heating line.

[0157] In these embodiments, the refrigeration assembly includes a first heat exchange device and a first refrigeration device. The first heat exchange device is connected to the heating pipeline and stores refrigerant. The first heat exchange device is in communication with the first refrigeration device, and the first refrigeration device is capable of cooling the refrigerant in the first heat exchange device. The refrigerant stored in the first heat exchange device is used to exchange heat with the heating pipeline. After the first refrigeration device cools the refrigerant, the heating pipeline is cooled by heat exchange between the first heat exchange device and the heating pipeline.

[0158] First, the heating element is controlled to operate, and the temperature detection device continuously detects the temperature of the heating pipeline. When it is detected that the temperature of the heating pipeline has risen to the first set temperature, the first refrigeration device is controlled to cool the refrigerant in the first heat exchange device. The refrigerant in the first heat exchange device exchanges heat with the heating pipeline, thereby cooling the heating pipeline. Under the action of the first refrigeration device, the refrigerant in the first heat exchange device drops to the second set temperature. The temperature detection device continuously detects the temperature of the heating pipeline. When it is detected that the temperature of the heating pipeline has reached the third set temperature, the infusion component is controlled to deliver liquid into the heating pipeline to flush out the scale that has fallen off the heating pipeline.

[0159] It can be understood that the value range of the first set temperature is 100℃ to 120℃, the value range of the second set temperature is -10℃ to -3℃, and the value range of the third set temperature is -5℃ to 0℃. By heating the heating pipeline to the first set temperature and the refrigerant in the refrigeration component drops to the second set temperature, it can be ensured that during the descaling process. There is a large temperature difference in the temperature value of the heating pipeline, which ensures the descaling effect on the heating pipeline. The value range of the first set temperature is close to the operating temperature of the heating device, which avoids aging and damage caused by excessive temperature of the heating pipeline and heating element. The value range of the third set temperature is between the second set temperature and the first set temperature.

[0160] like Figure 6 As shown, in some embodiments, the refrigeration assembly includes a second heat exchange device, a first pump body and a second refrigeration device.

[0161] The second refrigeration device is capable of storing and cooling the refrigerant, and the second refrigeration device is connected to the second heat exchange device through a refrigerant pipeline;

[0162] The first pump body is arranged on the refrigerant pipeline and can pump the refrigerant in the second refrigeration device into the second heat exchange device;

[0163] The second heat exchange device is in contact with the heating pipeline and can perform heat exchange and temperature reduction on the heating pipeline.

[0164] A control method for a liquid processing device, specifically comprising:

[0165] Step 602, in response to the descaling instruction, controlling the second refrigeration device to cool the refrigerant;

[0166] Step 604: Determine whether the refrigerant in the second refrigeration device has dropped to the second set temperature. If yes, proceed to step 606; otherwise, return to step 602.

[0167] Step 606, controlling the heating element to start operation;

[0168] Step 608, detecting the temperature of the heating pipe;

[0169] Step 610, determining whether the temperature of the heating pipe has risen to the first set temperature, if so, executing step 612, otherwise, returning to executing step 608;

[0170] Step 612, controlling the first pump to pump the refrigerant in the second refrigeration device to the second heat exchange device;

[0171] Step 614, determining whether the temperature of the heating pipe has dropped to a third set temperature value. If so, proceed to step 616; otherwise, return to step 612.

[0172] Step 616, controlling the infusion component to operate to flush the heating line.

[0173] In this embodiment, the refrigeration assembly includes a second heat exchange device, a second refrigeration device and a first pump body. The second refrigeration device can not only cool the refrigerant, but also store the refrigerant. The second heat exchange device is connected to the heating pipeline, and the second heat exchange device can exchange heat with the heating pipeline, thereby cooling and cooling the heating pipeline. The refrigerant pipeline is arranged between the second heat exchange device and the second refrigeration device, and the operation of the first pump body can pump the refrigerant in the second refrigeration device into the second heat exchange device. During the descaling process of the heating pipeline, the second refrigeration device can be controlled to operate first, and the operation of the second refrigeration device can cool and cool the refrigerant stored in the second refrigeration device. The cooled and cooled refrigerant is temporarily stored in the second device. At this time, the heating element is controlled to operate to heat the heating pipeline. After the heating step of the heating pipeline is completed, the first pump body is controlled to operate to pump the refrigerant in the second refrigeration device into the second heat exchange device, so that the second heat exchange device can exchange heat with the heating pipeline.

[0174] During the descaling process of the heating pipeline, before the step of controlling the operation of the heating element, the second refrigeration device is operated to cool the refrigerant stored in the second refrigeration device, so that the temperature of the refrigerant drops to the second set temperature. Before the heating element heats the heating pipeline, the refrigerant used to cool the heating pipeline is cooled. After the heating pipeline is heated to the first set temperature, the lower temperature refrigerant is directly transported to the second heat exchange device, so that the second heat exchange device can quickly cool the heating pipeline. After the heating pipeline temperature rises, there is no need to reserve cooling time for the refrigerant, thereby improving the efficiency of descaling the heating pipeline.

[0175] During the descaling process of the heating pipeline, when the temperature of the heating pipeline rises to the first temperature, the first pump body is operated to transport the refrigerant in the second refrigeration device to the second heat exchange device. Before the heating pipeline is heated and heated, the refrigerant temperature in the second refrigeration device has already dropped to the second set temperature. During the cooling process of the heating pipeline, the refrigerant that has dropped to the second set temperature is directly transported to the second heat exchange device, thereby rapidly reducing the temperature of the heating pipeline and improving the descaling effect on the heating pipeline.

[0176] It can be understood that the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0177] like Figure 7 As shown, in some embodiments, the refrigeration assembly includes a reversing valve, a liquid inlet pipeline, and a third refrigeration device.

[0178] The reversing valve includes a first end, a second end, and a third end. The first end is connected to the infusion assembly, the second end is connected to the third refrigeration device, and the third end is connected to the liquid inlet pipeline.

[0179] The third refrigeration device can cool down the refrigerant, and the infusion component can be filled with liquid through the liquid inlet pipeline.

[0180] A control method for a liquid processing device, specifically comprising:

[0181] Step 702, in response to the descaling instruction, controlling the heating element to start operation;

[0182] Step 704, detecting the temperature of the heating pipe;

[0183] Step 706, determining whether the temperature of the heating pipe has risen to the first set temperature, if so, executing step 708, otherwise, returning to executing step 704;

[0184] Step 708, controlling the third refrigeration device to cool the refrigerant;

[0185] Step 710, determining whether the refrigerant in the third refrigeration device has dropped to the second set temperature. If yes, proceed to step 712; otherwise, return to step 708;

[0186] Step 712: Control the reversing valve to connect the third refrigeration device to the infusion assembly, and control the infusion assembly to pump the refrigerant into the heating pipeline;

[0187] Step 714, controlling the reversing valve to connect the liquid inlet line to the infusion assembly, and controlling the infusion assembly to operate to flush the heating line.

[0188] In this embodiment, the refrigeration assembly includes a liquid inlet line, a reversing valve, and a third refrigeration device. After cooling the refrigerant, the third refrigeration device delivers the refrigerant to the infusion assembly, which then delivers the refrigerant to the heating line, thereby cooling the heating line. By directly introducing the refrigerant into the heating line to be cooled, the temperature of the heating line can be rapidly reduced, improving the efficiency of cooling and descaling the heating line.

[0189] In some embodiments, the third refrigeration device can not only cool the refrigerant, but also store the refrigerant. Before the heating pipeline is heated and heated, the third refrigeration device is controlled to cool the refrigerant stored inside. At this time, the reversing valve connects the liquid inlet pipeline with the infusion component, that is, the third refrigeration device is not connected to the heating pipeline, ensuring that the refrigerant in the third refrigeration device will not flow into the heating pipeline. When the heating pipeline is heated and heated to the first set temperature, the reversing valve is controlled to operate, connecting the third refrigeration device with the infusion component, and the refrigerant in the third refrigeration device flows into the heating pipeline to cool the heating pipeline. Since the refrigerant has reached the second set temperature before the heating pipeline reaches the first set temperature, the refrigerant that has dropped to the second set temperature is directly transported to the heating pipeline, so that the temperature of the heating pipeline is rapidly reduced, thereby improving the descaling effect on the heating pipeline.

[0190] In other embodiments, the heating element is first controlled to heat the heating line. During the heating process, the reversing valve connects the liquid inlet line to the infusion assembly, that is, the third refrigeration unit is disconnected from the heating line, ensuring that the refrigerant in the third refrigeration unit does not flow into the heating line. When the heating line is heated to a first set temperature, the reversing valve is controlled to operate, connecting the third refrigeration unit to the infusion assembly, and the third refrigeration unit begins to operate to cool the refrigerant. When the refrigerant drops to a second temperature, the infusion assembly is controlled to deliver the refrigerant to the heating line to cool the heating line.

[0191] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0192] In any of the above embodiments, the refrigerant can be selected as a refrigerant such as brine to ensure that the refrigerant does not solidify when it reaches the second set temperature, to ensure the fluidity of the refrigerant, and to avoid refrigerant blockage that causes failure of cooling the heating pipeline.

[0193] Specifically, the refrigerant is selected as edible salt water, which prevents the refrigerant from contaminating the heating pipeline when the refrigerant flows through the heating pipeline.

[0194] like Figure 8As shown, in any of the above embodiments, the infusion assembly includes an infusion pipeline, a liquid outlet pipeline and a second pump body.

[0195] The infusion pipeline and the discharge pipeline are both connected to the heating pipeline;

[0196] The second pump body is arranged on the liquid infusion pipeline. When the second pump body is in operation, the liquid enters the heating pipeline through the liquid infusion pipeline and is discharged from the heating pipeline through the liquid outlet pipeline.

[0197] The steps of controlling the operation of the infusion component to flush the heated tubing include:

[0198] Step 802, detecting the temperature of the heating pipeline;

[0199] Step 804 : When the temperature of the heating pipeline drops to a third set temperature, control the second pump body to infuse liquid into the heating pipeline.

[0200] The third set temperature is lower than the first set temperature.

[0201] In this embodiment, the infusion assembly includes an infusion line, a discharge line, and a second pump. Both the infusion line and the discharge line are connected to the heating line in the heating device. The second pump is controlled to pump the liquid in the infusion line into the heating line. As the second pump continues to operate, the liquid that has entered the heating line is discharged through the discharge line. By incorporating the infusion assembly into the liquid handling device, the fluidity of the liquid in the heating line is guaranteed, ensuring the efficient heating of the liquid by the liquid handling device.

[0202] During the process of the refrigeration component cooling the heating pipeline, the temperature value of the heating pipeline is continuously detected. When it is detected that the temperature value of the heating pipeline drops to the third set temperature, it is determined that most of the scale in the heating pipeline has fallen off at this time, and the second pump body is controlled to operate to input liquid from an external liquid source into the heating pipeline to flush and clean the scale in the heating pipeline, so as to avoid the scale being discharged from the device along with the heated liquid during normal use of the liquid treatment device, affecting the user experience.

[0203] In any of the above embodiments, after the step of controlling the infusion assembly to flush the heating line, the method further includes:

[0204] The number of times the infusion component infuses the heating pipeline is determined. If it is determined that the number of times the infusion component infuses the heating pipeline is less than the set number, the process returns to the step of controlling the heating element to heat the heating pipeline.

[0205] In this embodiment, to improve the effectiveness of descaling the heating device, the heating, cooling, and water delivery steps can be cycled through the heating pipeline multiple times. Upon receiving the descaling instruction, the liquid handling device determines the number of descaling steps required, i.e., the set number of times the infusion assembly has been operated. If the infusion assembly has not delivered water to the heating pipeline for the set number of flushes, the device returns to heating the heating pipeline with the heating element. Upon detecting that the set number of flushes has been reached, the descaling process for the liquid handling device is complete, and the device is controlled to cease operation.

[0206] Example 3:

[0207] like Figure 9 As shown, in the first embodiment of the present invention, a control device 900 for a liquid treatment device is provided for controlling the operation of the liquid treatment device, which includes: an infusion component, a heating device, and a refrigeration component. The heating device includes a heating element and a heating pipeline. The heating pipeline is connected to the infusion component, and the heating element can heat the liquid flowing through the heating pipeline; the refrigeration component is connected to the heating pipeline, and the refrigeration component can cool the heating pipeline. The control device 900 for the liquid treatment device specifically includes:

[0208] The first control module 902 is configured to control the second refrigeration device to cool the refrigerant in response to the descaling instruction;

[0209] The second control module 904 is used to control the refrigeration component to operate when the temperature of the heating pipeline is raised to a first set temperature, so as to cool the heating pipeline;

[0210] The third control module 906 is used to control the operation of the infusion component to flush the heating pipeline.

[0211] The control device provided in an embodiment of the present invention is used to control a liquid handling device. The liquid handling device includes an infusion assembly, a heating device, and a refrigeration assembly. The heating device includes a heating pipeline and a heating element. The heating pipeline is connected to the infusion assembly. The infusion assembly can transport liquid into the heating pipeline. The heating element is operated to heat the liquid in the heating pipeline. During the heating operation of the liquid handling device, the infusion assembly operates to transport external liquid into the heating device. After the liquid enters the heating device, it flows in the heating pipeline. The heating element is powered on and operates to heat the heating pipeline. The heat is then transferred through the heating pipeline to the liquid in the heating pipeline, thereby heating the liquid.

[0212] In some embodiments, the heating device is a channel-type heating device for use in a steamer, wherein the heating element is an electric heating element. Upon receiving a start command, the heating device controls the electric heating element to heat the heating pipe. When the heating pipe reaches a preset temperature, the device controls the infusion assembly to deliver water into the heating pipe. The water enters the high-temperature heating pipe and is atomized, and the atomized water vapor is discharged from the heating device.

[0213] During the use of the heating device, scale is easily formed on the inner wall of the heating pipeline. When the heating device stops running, the scale in the heating pipeline can be removed by controlling the operation of the refrigeration component. Specifically, in the process of removing scale, the heating element is first controlled to heat the heating pipeline. When the temperature of the heating pipeline rises to the first set temperature, the refrigeration component is controlled to cool the heating pipeline. Since the thermal expansion and contraction coefficients of the heating pipeline and the scale on the pipeline wall are different, the scale on the pipeline wall of the heating pipeline is affected by the thermal expansion and contraction of the objects, causing it to fall off. After the scale falls off, the infusion component is controlled to supply water to the heating device. The water flowing through the heating pipeline can flush the scale out of the heating pipeline, thereby preventing the scale from being discharged from the device along with the heated liquid during normal use of the liquid treatment device, affecting the user experience.

[0214] The present invention provides a refrigeration component for cooling the heating pipeline in the heating device in the liquid treatment device. By first heating the heating pipeline and then cooling the heating pipeline at a higher temperature, the heating pipeline undergoes a wide temperature change in a short period of time, thereby causing scale in the heating pipeline to fall off. The scale in the heating pipeline is then flushed away by the infusion component. Since the refrigeration component is provided in the liquid treatment device, it is not necessary to heat the heating pipeline to an excessively high temperature, and a large temperature difference between hot and cold in the heating pipeline can be ensured. Under the premise of achieving the removal of scale in the heating pipeline, the problem of pipeline aging and damage caused by excessively high temperature in the heating pipeline is avoided.

[0215] In some embodiments, the refrigeration assembly includes: a first heat exchange device and a first refrigeration device.

[0216] The second control module 904 is specifically configured to control the first refrigeration device to cool the refrigerant in the first heat exchange device to a second set temperature.

[0217] In this embodiment, the refrigeration assembly includes a first heat exchange device and a first refrigeration device. The first heat exchange device is connected to the heating pipeline and stores refrigerant. The first heat exchange device is in communication with the first refrigeration device, and the first refrigeration device is capable of cooling the refrigerant in the first heat exchange device. The refrigerant stored in the first heat exchange device is used to exchange heat with the heating pipeline. After the first refrigeration device cools the refrigerant, the heating pipeline is cooled by heat exchange between the first heat exchange device and the heating pipeline.

[0218] First, the heating element is controlled to operate, and the temperature detection device continuously detects the temperature of the heating pipeline. When it is detected that the temperature of the heating pipeline has risen to the first set temperature, the first refrigeration device is controlled to cool the refrigerant in the first heat exchange device. The refrigerant in the first heat exchange device exchanges heat with the heating pipeline, thereby cooling the heating pipeline. Under the action of the first refrigeration device, the refrigerant in the first heat exchange device drops to the second set temperature. The temperature detection device continuously detects the temperature of the heating pipeline. When it is detected that the temperature of the heating pipeline has reached the third set temperature, the infusion component is controlled to deliver liquid into the heating pipeline to flush out the scale that has fallen off the heating pipeline.

[0219] It can be understood that the value range of the first set temperature is 100℃ to 120℃, the value range of the second set temperature is -10℃ to -3℃, and the value range of the third set temperature is -5℃ to 0℃. By heating the heating pipeline to the first set temperature and the refrigerant in the refrigeration component drops to the second set temperature, it can be ensured that during the descaling process. There is a large temperature difference in the temperature value of the heating pipeline, which ensures the descaling effect on the heating pipeline. The value range of the first set temperature is close to the operating temperature of the heating device, which avoids aging and damage caused by excessive temperature of the heating pipeline and heating element. The value range of the third set temperature is between the second set temperature and the first set temperature.

[0220] In any of the above embodiments, the refrigeration assembly includes a second heat exchange device, a first pump body and a second refrigeration device.

[0221] The second refrigeration device is capable of storing and cooling the refrigerant, and the second refrigeration device is connected to the second heat exchange device through a refrigerant pipeline;

[0224] The second control module 904 is specifically used to control the second refrigeration device to cool the refrigerant temperature in the second refrigeration device to the second set temperature. When the heating pipeline is heated to the first set temperature, the first pump body is controlled to pump the refrigerant in the second refrigeration device into the second heat exchange device.

[0225] In this embodiment, the refrigeration assembly includes a second heat exchange device, a second refrigeration device and a first pump body. The second refrigeration device can not only cool the refrigerant, but also store the refrigerant. The second heat exchange device is connected to the heating pipeline, and the second heat exchange device can exchange heat with the heating pipeline, thereby cooling and cooling the heating pipeline. The refrigerant pipeline is arranged between the second heat exchange device and the second refrigeration device, and the operation of the first pump body can pump the refrigerant in the second refrigeration device into the second heat exchange device. During the descaling process of the heating pipeline, the second refrigeration device can be controlled to operate first, and the operation of the second refrigeration device can cool and cool the refrigerant stored in the second refrigeration device. The cooled and cooled refrigerant is temporarily stored in the second device. At this time, the heating element is controlled to operate to heat the heating pipeline. After the heating step of the heating pipeline is completed, the first pump body is controlled to operate to pump the refrigerant in the second refrigeration device into the second heat exchange device, so that the second heat exchange device can exchange heat with the heating pipeline.

[0226] During the descaling process of the heating pipeline, before the step of controlling the operation of the heating element, the second refrigeration device is operated to cool the refrigerant stored in the second refrigeration device, so that the temperature of the refrigerant drops to the second set temperature. Before the heating element heats the heating pipeline, the refrigerant used to cool the heating pipeline is cooled. After the heating pipeline is heated to the first set temperature, the lower temperature refrigerant is directly transported to the second heat exchange device, so that the second heat exchange device can quickly cool the heating pipeline. After the heating pipeline temperature rises, there is no need to reserve cooling time for the refrigerant, thereby improving the efficiency of descaling the heating pipeline.

Before the heating pipeline is heated and heated, the refrigerant temperature in the second refrigeration device has already dropped to the second set temperature. During the cooling process of the heating pipeline, the refrigerant that has dropped to the second set temperature is directly transported to the second heat exchange device, thereby rapidly reducing the temperature of the heating pipeline and improving the descaling effect on the heating pipeline.

[0228] It can be understood that the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0229] In some embodiments, the refrigeration assembly includes a reversing valve, a liquid inlet pipeline, and a third refrigeration device.

[0231] The third refrigeration device can cool down the refrigerant, and the infusion component can be filled with liquid through the liquid inlet pipeline.

[0232] The second control module 904 is specifically configured to control the third refrigeration device to cool the refrigerant. When the refrigerant in the third refrigeration device drops to a second set temperature, the second control module 904 controls the reversing valve to connect the third refrigeration device to the infusion assembly, controls the infusion assembly to pump the refrigerant into the heating pipeline, and controls the reversing valve to connect the liquid inlet pipeline to the infusion assembly.

[0233] The third control module 906 is specifically used to control the operation of the infusion component to flush the heating pipeline.

[0234] In this embodiment, the refrigeration assembly includes a liquid inlet line, a reversing valve, and a third refrigeration device.

[0237] In these embodiments, the first set temperature ranges from 100°C to 120°C, the second set temperature ranges from -10°C to -3°C, and the third set temperature ranges from -5°C to 0°C.

[0238] In any of the above embodiments, the refrigerant can be selected as a refrigerant such as brine to ensure that the refrigerant does not solidify when it reaches the second set temperature, to ensure the fluidity of the refrigerant, and to avoid refrigerant blockage that causes failure of cooling the heating pipeline.
