Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of intelligent kitchen appliances, and in particular to an intelligent kitchen appliance and a heat exchange control method thereof. BACKGROUND

[0002] With the improvement of people's living quality and the popularization of Internet, big data, artificial intelligence, voice interaction and other technologies, more and more traditional lifestyles are gradually changing, and the use of kitchen appliances has gradually moved towards intelligentization. While bringing more convenience to users, the functions of various kitchen appliances tend to be diversified. For example, the function of traditional water purification equipment is no longer limited to providing pure drinking water, but is combined with ice making function to produce a water purification and ice making all-in-one machine that can directly produce ice cubes, providing great convenience to users.

[0003] While bringing convenience, the water purification and ice making all-in-one machine also introduces new technical challenges, the core of which is the waste heat emission problem generated during the operation of its ice making component. Taking the existing ice maker based on compressor refrigeration cycle as an example, there are two ways to dissipate the heat of high-temperature gaseous refrigerant in the condenser: one is water cooling, which removes the high temperature of the refrigerant through cooling water, and absorbs heat through the flow of cooling water in the condensing pipe. The second is air cooling, which blows away the high temperature of the refrigerant through a fan, relying on air flow to dissipate heat. Among them, the water cooling method needs to use cooling water continuously, resulting in a large waste of water resources. The air cooling method is greatly affected by the environment temperature, and the heat dissipation efficiency will decrease in high temperature environment, affecting the ice making efficiency, and the work of the fan will also produce high noise.

[0046] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0047] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0048] The smart kitchen appliance disclosed in this embodiment has an ice-making function, specifically including a water purification component and an ice-making component. The ice-making component includes a hot water exchange tank and a cold water tank. The water purification component pressurizes raw water through a booster pump to produce purified water and wastewater. The wastewater flows into the hot water exchange tank for heat exchange with the heat-generating end of the ice-making component; the purified water flows into the cold water tank to serve as the ice-making water source. In some examples, the smart kitchen appliance may also include a heating component for heating the purified water to provide hot water to the user.

[0049] In some examples, the ice-making assembly includes a thermoelectric cooler, and the heat-dissipating end of the ice-making assembly is the hot end of the thermoelectric cooler. In this example, when the thermoelectric cooler is powered on, its cold end absorbs heat for ice making, while the hot end simultaneously generates and accumulates heat far exceeding the amount absorbed by the cold end.

[0050] In other examples, the ice-making assembly includes a condenser, with the heat-dissipating end of the ice-making assembly being the condenser. In practical applications, the ice-making assembly also includes other components for ice making, such as a compressor, evaporator, ice maker, and water pump.

[0051] Specifically, the kitchen appliances mentioned can be water purification equipment, direct drinking water equipment, water purification and ice making integrated machines, ice and water integrated machines, etc. Figure 1 This is a schematic diagram illustrating the water circuit structure of a water purification device. Figure 1 In the example shown, the water purification equipment can meet users' needs for room temperature water, hot water, and ice, specifically including a water purification component, a heating component, and an ice-making component. The water outlet of the water purification component is connected to the water inlet of the heating component and the water inlet of the ice-making component. The water purification component includes a pre-filter, a pressure reducing valve, a booster pump, a nanofiltration membrane filter, and a post-filter, etc. The heating component includes a negative pressure valve, a hot water pump, and a thick-film heating element, etc. The ice-making component includes a cold water tank, a compressor, an evaporator, a condenser, a hot water exchange tank, an inlet pump, a rotary ice maker, and a refrigerator, etc.

[0052] like Figure 1As shown, when raw water, i.e., tap water, enters through the inlet electric valve 10, it passes sequentially through the pre-filter 11, pressure reducing valve 12, booster pump 13, nanofiltration membrane filter 14, and post-filter 15 to produce purified water and wastewater. The purified water is controlled by the ambient temperature water solenoid valve 16 to directly output ambient temperature water, or it passes through the negative pressure valve 17, hot water pump 18, and thick-film heating element 19 to obtain hot water at different levels, or it is controlled by the inlet solenoid valve 20 to enter the cold water tank 21. When the ice-making function is activated, the inlet pump 22 draws water from the cold water tank into the rotating ice-making tank 23, where ice is made under the combined action of the compressor, evaporator, and condenser. After the ice is made, it is temporarily stored in the refrigerator 24, and when the user wants to retrieve the ice, it is discharged from the ice outlet 25. The wastewater is controlled by the wastewater switch valve 26 and the wastewater proportional valve 27 to enter the hot water exchange tank 28 for heat exchange with the condenser.

[0053] This disclosure provides a heat exchange control method for a smart kitchen appliance. During the ice-making process, wastewater generated by the water purification component is used to exchange heat with the heat-releasing end of the ice-making component. The target flow rate of the wastewater is determined based on the principle that the heat required for heat exchange is the same as the heat required for ice making. Based on this, the operation of the booster pump is controlled so that the actual flow rate of the wastewater reaches the target flow rate, thereby achieving the effect of energy-saving heat exchange.

[0054] In this embodiment of the disclosure, the smart kitchen appliance equipped with a water purification component and an ice-making component has a heat exchange control device. The heat exchange control device includes an acquisition module, a determination module, and a control module. The acquisition module responds to the user's ice-making needs by acquiring the current water temperature of the hot water tank and the current water temperature of the cold water tank. The determination module determines the target flow rate of the generated wastewater. The control module controls the operation of the booster pump, thereby realizing intelligent regulation of the booster pump and improving the user experience of using the smart kitchen appliance.

[0055] Example 1

[0056] Figure 2 This is a flowchart illustrating a heat exchange control method for a smart kitchen appliance provided in this embodiment. This heat exchange control method can be executed by a heat exchange control device, which can be implemented through software and / or hardware. The heat exchange control device can be part or all of the smart kitchen appliance. The following description uses the smart kitchen appliance as the executing entity to illustrate the heat exchange control method provided in this embodiment.

[0057] like Figure 2 As shown, the heat exchange control method provided in this embodiment may include the following steps S11~S13:

[0058] Step S11: In response to the ice-making demand, obtain the current water temperature of the hot water tank and the current water temperature of the cold water tank, respectively. The ice-making demand includes the amount of ice to be made, which can be the mass or volume of ice blocks. In some examples, the ice-making demand also includes the ice-making time.

[0059] In practical applications, users typically initiate ice-making requests. This can be done by inputting the required amount of ice or the desired ice-making time through the smart kitchen appliance's interface, or via voice commands; the specific method is not limited. In some examples, the user inputs the number of ice cubes. In this case, the required ice mass needs to be determined based on the preset mass of each ice cube and the quantity of ice cubes. The mass of each ice cube can be preset to a fixed value or selected by the user. In specific implementations, temperature sensors can be installed in both the hot water tank and the cold water tank to detect the water temperature.

[0060] It should be noted that in some examples, the aforementioned cold water tank is also referred to as a normal temperature water tank, water tank, etc.

[0061] Step S12: Determine the target flow rate of the wastewater based on the current water temperature of the hot water tank, the current water temperature of the cold water tank, and the ice-making requirement.

[0062] In this embodiment of the disclosure, during the ice-making process, wastewater from the hot water exchange tank exchanges heat with the heat-generating end of the ice-making component. To achieve energy-saving heat exchange, according to the principle of energy conservation, the heat required for heat exchange is equal to the heat required for ice making. Specifically:

[0063] The heat required for heat exchange = temperature difference between the hot water tank and the hot water tank × mass flow rate of wastewater × specific heat capacity of water;

[0064] The amount of heat required to make ice = temperature difference in the cold water tank × mass flow rate of ice × specific heat capacity of water;

[0065] Since the heat exchange time and the ice-making time are the same, the following equation can be obtained:

[0066] Temperature difference in hot water tank × required wastewater mass = temperature difference in cold water tank × required ice production capacity.

[0067] The temperature difference in the hot water tank is the difference between the water temperature after ice making and the current water temperature, while the temperature difference in the cold water tank is the difference between the water temperature after ice making and the current water temperature. The water temperature in the hot water tank after ice making can be set according to actual conditions. In some examples, if the water temperature in the hot water tank exceeds the preset temperature, it will affect the heat exchange efficiency, requiring the wastewater in the hot water tank to be replaced. In this case, the water temperature in the hot water tank after ice making can be set to the preset temperature, for example, 40℃. The water temperature in the cold water tank after ice making is usually 0℃.

[0068] Step S13: Control the operation of the booster pump according to the target flow rate. In specific implementation, the speed and power of the booster pump can be controlled according to the target flow rate so that the actual flow rate of the wastewater reaches the target flow rate, thereby achieving the effect of energy-saving heat exchange.

[0069] In one alternative implementation, such as Figure 3 As shown, step S13 specifically includes:

[0070] Step S131a: Obtain the set temperature corresponding to the target flow rate. In specific implementations, the correspondence between the wastewater flow rate and the set temperature of the hot water exchange tank needs to be determined in advance. Based on this correspondence, the set temperature corresponding to the target flow rate can be obtained.

[0071] In practical applications, the relationship between wastewater flow rate and the set temperature of the hot water exchange tank varies under different ambient temperatures. To improve accuracy, the set temperature corresponding to the target flow rate can be obtained based on the ambient temperature.

[0072] Step S131b: Determine the control flow rate based on the set temperature and the current water temperature of the hot water exchange tank. In specific implementation, the difference between the set temperature and the current water temperature of the hot water exchange tank can be input into the controller to obtain the corresponding control quantity, i.e., the control flow rate. The controller may employ a PI control algorithm, PID control algorithm, fuzzy control algorithm, etc.

[0073] In an example where the controller uses the PID control algorithm:

[0074] η= Kp1×e(t) + Ki1×Σe(t) + Kd1×( e(t) - e(t-1)).

[0075] Where e(t) is the difference between the set temperature at time t and the water temperature in the hot water tank, e(t-1) is the difference between the set temperature at time t-1 and the water temperature in the hot water tank, Kp1, Ki1, and Kd1 are the system parameters of the controller, and η is the output of the controller, i.e., the control flow rate.

[0076] Step S131c: Control the operation of the booster pump according to the operating parameters corresponding to the controlled flow rate; wherein, the operating parameters are the operating parameters of the booster pump, such as speed, power, etc. In specific implementation, the correspondence between the wastewater flow rate and the booster pump operating parameters needs to be determined in advance. Based on this correspondence, the operating parameters corresponding to the controlled flow rate can be obtained, and the operation of the booster pump can be controlled according to these operating parameters.

[0077] This implementation method does not require a flow meter for detecting wastewater flow. Instead, it uses closed-loop control of the booster pump based on the temperature deviation between the set temperature of the hot water tank and the current water temperature, so that the actual flow rate of the wastewater can reach the target flow rate.

[0078] In another alternative implementation, such as Figure 4 As shown, step S13 specifically includes:

[0079] Step S132a: Obtain the actual flow rate of the wastewater. In specific implementations, a flow meter can be installed in the pipeline to detect the actual flow rate of the wastewater.

[0080] Step S132b: Adjust the operating parameters of the booster pump according to the flow deviation between the target flow rate and the actual flow rate. In a specific implementation, the flow deviation between the target flow rate and the actual flow rate can be input into the controller to obtain the corresponding control quantity, i.e., the operating parameters of the booster pump, and the operation of the booster pump can be directly controlled according to these operating parameters.

[0081] In this embodiment, the operation of the booster pump is controlled in a closed loop based on the flow deviation between the actual flow rate and the target flow rate of the wastewater, so that the actual flow rate of the wastewater can reach the target flow rate.

[0082] In some examples, a circulation pump is connected between the inlet and outlet of the hot water exchange tank. To improve the heat exchange efficiency at the heat dissipation end, the circulation pump can be activated to agitate the hot water exchange tank.

[0083] In one optional embodiment, the outlet of the hot water exchange tank is connected to a drain pipe via a drain valve. The heat exchange control method further includes: in response to the water temperature of the hot water exchange tank exceeding a preset temperature, controlling the drain valve to open for a preset duration; wherein the preset temperature is related to the heat exchange efficiency of the condenser, and the preset duration is determined based on the volume of the hot water exchange tank.

[0084] In practice, different heat-generating ends may have different heat exchange efficiencies due to differences in structure, materials, etc. In a specific example, the heat-generating end of the ice-making component is a condenser, and 30℃~45℃ is the optimal heat dissipation temperature of the condenser, that is, the heat exchange efficiency of the condenser can reach its optimal level at this temperature. Therefore, the preset temperature can be set to any temperature within this range, such as 40℃.

[0085] In practice, a flow meter can be installed in the drain pipe to detect the water flow rate during drainage. Then, the preset opening time T of the drain valve can be calculated based on the volume V of the hot water tank and the corresponding water flow rate Q. Specifically, T = V / Q.

[0086] In this embodiment, when the water temperature in the hot water exchange tank exceeds the preset temperature, if the wastewater in the hot water exchange tank continues to be used for heat exchange with the heat release end, it will affect the heat exchange efficiency of the heat release end. By replacing the wastewater in the hot water exchange tank, the heat exchange efficiency of the heat release end can be improved, thereby improving the ice-making efficiency.

[0087] This embodiment also provides a heat exchange control device for intelligent kitchen appliances, such as... Figure 5 As shown, the system includes an acquisition module 71, a determination module 72, and a control module 73. The acquisition module 71 acquires the current water temperature of the hot water tank and the current water temperature of the cold water tank in response to ice-making demand; wherein the ice-making demand includes the amount of ice to be made. The determination module 72 determines the target flow rate of the wastewater based on the current water temperature of the hot water tank, the current water temperature of the cold water tank, and the ice-making demand. The control module 73 controls the operation of the booster pump based on the target flow rate.

[0088] In one optional implementation, the control module is specifically used to acquire a set temperature corresponding to the target flow rate; determine a control flow rate based on the set temperature and the current water temperature of the hot water exchange tank; and control the operation of the booster pump based on the operating parameters corresponding to the control flow rate; wherein the operating parameters are the operating parameters of the booster pump.

[0089] In one optional implementation, the control module is specifically used to obtain a set temperature corresponding to the target flow rate based on the ambient temperature.

[0090] In one optional implementation, the control module is specifically used to acquire the actual flow rate of the wastewater; and to adjust the operating parameters of the booster pump according to the flow deviation between the target flow rate and the actual flow rate.

[0091] In one optional embodiment, a circulation pump is connected between the inlet and outlet of the hot water tank; the control module is also used to control the circulation pump to start in response to ice-making demand.

[0092] In one optional embodiment, the outlet of the hot water exchange tank is connected to a drain pipe via a drain valve, and the control module is further configured to control the drain valve to open for a preset duration in response to the water temperature of the hot water exchange tank exceeding a preset temperature; wherein, the preset temperature is related to the heat exchange efficiency of the heat-releasing end of the ice-making component, and the preset duration is determined according to the volume of the hot water exchange tank.

[0093] It should be noted that the heat exchange control device in this embodiment can be a separate chip, chip module, or smart kitchen appliance, or it can be a chip or chip module integrated into a smart kitchen appliance.
