[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following is for reference. Figures 1-5 An integrated stove 100 according to a first aspect embodiment of the present invention is described.

[0043] like Figure 1 As shown, the integrated stove 100 according to a first aspect embodiment of the present invention includes: an integrated stove body 1 and a heat dissipation assembly 2.

[0044] Specifically, the integrated stove body 1 includes a body 11 and a cooktop panel 12. The cooktop panel 12 is located on top of the body 11, and a heat dissipation component 2 is located on the body 11. The heat dissipation component 2 is used to cool the cooktop panel 12. Since the cooktop panel 12 is usually close to the flame, the temperature of the cooktop panel 12 is high during the long-term use of the integrated stove 100. On the one hand, it is easy for the operator to be burned when accidentally touching the control panel. On the other hand, since the cooktop panel 12 often uses tempered glass, the tempered glass is prone to generating large thermal stress inside when heated, which poses a risk of breakage or explosion. By setting the heat dissipation component 2 for the cooktop panel 12, it is beneficial to dissipate heat from the cooktop panel 12 in a timely manner, reduce the temperature, and thus reduce the risk of accidental burns or breakage of the cooktop panel 12.

[0045] For example, the body 11 can be roughly cube-shaped, and the body 11 can define a receiving cavity with an opening on one side (e.g., the top side). The integrated stove body 1 can also include a stove platform, which is located on top of the receiving cavity. The top of the stove platform can have an mounting opening suitable for mounting the stove panel 12. The stove panel 12 can be embedded in the mounting opening and remain flush with the perimeter of the top wall of the body 11. The stove panel 12 can be tempered glass. The heat dissipation component 2 can be located inside the receiving cavity, or the heat dissipation component 2 can be located on the stove platform and below the stove panel 12, or part of the heat dissipation component 2 can be located in the receiving cavity and the other part can be located on the stove platform and below the stove panel 12. The heat dissipation component 2 can use air cooling, water cooling, or other cooling methods to dissipate heat and cool the stove panel 12. Of course, the present invention is not limited to these, and the specific cooling method of the heat dissipation component 2 can be reasonably selected as needed.

[0046] According to the integrated stove 100 of the present invention, by providing a heat dissipation component 2 for the stove panel 12, the stove panel 12 can dissipate heat in time and reduce the temperature, thereby reducing the risk of burns or breakage of the stove panel 12 due to accidental contact and improving safety.

[0047] Alternatively, the cooktop panel 12 may be a tempered glass panel, or a panel made of stainless steel or other materials.

[0048] In some embodiments, the heat dissipation assembly 2 may include a heat-conducting element 20. Specifically, the heat-conducting element 20 is disposed on the top of the body 11, or on the bottom surface of the cooktop panel 12, and is in contact with the cooktop panel 12. For example, the heat-conducting element 20 may be a heat-conducting metal component, such as an aluminum plate or a copper plate. Heat dissipation fins may be formed on the heat-conducting element 20. The cooktop panel 12 contacts the heat-conducting element 20, allowing the cooktop panel 12 to transfer heat to the heat-conducting element 20 via thermal conduction, which then dissipates the heat to the outside. However, the invention is not limited to this; the heat-conducting element 20 may also dissipate heat from the cooktop panel 12 in other ways.

[0049] Further, refer to Figure 2 and Figure 3 The heat-conducting component 20 can be configured as a heat-conducting plate. A cooling channel 201 can be defined between the heat-conducting component 20 and the cooktop panel 12. The cooling channel 201 can be used for coolant flow, meaning that the heat dissipation component 2 can dissipate heat from the cooktop panel 12 through liquid cooling. Specifically, a cooling channel 201 is formed between the heat-conducting plate and the cooktop panel 12, and coolant is introduced into the cooling channel 201. The flow of coolant along the cooling channel 201 carries away the heat from the cooktop panel 12, thus improving the heat dissipation efficiency of the cooktop panel 12. Understandably, the coolant can circulate between the cooling channel 201 and the external device, thereby dissipating the heat absorbed from the cooktop panel 12 to the outside.

[0050] Furthermore, refer to Figure 3 The heat dissipation assembly 2 may further include: a liquid storage device 21, a coolant pump 23, and a heat exchange device 22. Specifically, the liquid storage device 21 can store coolant, and a liquid storage chamber 211 is defined within the liquid storage device 21. The liquid storage chamber 211 can be connected to the cooling channel 201. For example, the liquid storage chamber 211 and the cooling channel 201 can be configured to form a circulating connection. The liquid storage chamber 211 has an outlet (not shown) and an inlet (not shown), both of which are connected to the liquid storage chamber 211. The outlet of the liquid storage device 21 can be connected to the inlet end of the cooling channel 201, and the inlet of the liquid storage device 21 can be connected to the outlet end of the cooling channel 201. In this way, the liquid storage device 21 and the cooling channel 201 together form a circulating loop for coolant flow. The coolant pump 23 can drive the coolant to circulate between the cooling channel 201 and the liquid storage chamber 211. Optionally, the coolant pump 23 can be located between the inlet end of the cooling channel 201 and the outlet of the storage device 21, or the coolant pump 23 can also be located between the outlet end of the cooling channel 201 and the inlet of the storage device 21.

[0051] The heat exchange device 22 can be used to cool the coolant in the liquid storage chamber 211. For example, the heat exchange device 22 can be a tube-fin heat exchanger, or the heat exchange device 22 can be in the form of an aluminum block or aluminum alloy block wrapped around the heat exchange tube. Alternatively, the heat exchange device 22 can also be a phase change heat exchange device 22. Understandably, the specific form of the heat exchange device 22 can be reasonably selected according to the needs.

[0052] Optionally, one of the heat exchange device 22 and the liquid storage device 21 is located in the inner cavity of the other, and the inner cavity of the heat exchange device 22 and the inner cavity of the liquid storage device 21 are separated. For example, when the heat exchange device 22 is located in the liquid storage cavity 211 of the liquid storage device 21, the inner cavity of the heat exchange device 22 can be filled with a phase change material. In this way, when the coolant flows into the liquid storage cavity 211 of the liquid storage device 21 during the circulation process, it can exchange heat with the phase change material in the heat exchange device 22, thereby removing the heat absorbed by the coolant from the cooktop panel 12.

[0053] In some embodiments, reference Figure 3 A cooling groove is formed on the surface of the heat-conducting plate opposite to the cooktop panel 12. The bottom surface of the cooktop panel 12 and the inner wall of the cooling groove together define a cooling flow channel 201. Figure 3 As shown, a cooling groove is formed on the upper surface of the heat-conducting plate, and the cooktop panel 12 is placed on the heat-conducting plate. The upper side of the cooling groove is open, and the cooktop panel 12 can fit against the upper surface of the heat-conducting plate. In this way, the cooktop panel 12 can seal the cooling groove and also make the contact effect between the cooktop panel 12 and the heat-conducting plate better, thereby improving the heat dissipation effect of the cooktop panel 12.

[0054] Furthermore, the side of the cooktop panel 12 facing the heat-conducting plate can be provided with thermally conductive adhesive. The thermally conductive adhesive can not only improve the connection stability between the heat-conducting plate and the cooktop panel 12, but also help the cooktop panel 12 to better transfer heat to the heat-conducting plate or directly transfer heat to the coolant.

[0055] In some examples, a clearance hole 206 may be formed on the heat-conducting plate. The clearance hole 206 penetrates the heat-conducting plate along the thickness direction and can be used to avoid the burner head. The cooling channel 201 may include a main cooling section 202 distributed on the outer periphery of the clearance hole 206, and at least a portion of the main cooling section 202 is disposed adjacent to the clearance hole 206. When the integrated stove 100 is running, the portion of the stove panel 12 adjacent to the clearance hole 206 is closer to the flame, so the temperature of this portion is higher. And along the radial direction of the clearance hole 206 and from the inside to the outside, the temperature of the stove panel 12 gradually decreases. Therefore, distributing the main cooling section 202 on the outer periphery of the clearance hole 206 and distributing it at least a portion adjacent to the clearance hole 206 can ensure that the position of the stove panel 12 with the highest temperature and the greatest thermal stress is dissipated in time, thereby improving the heat dissipation effect of the stove panel 12, reducing the risk of the stove panel 12 cracking due to high thermal stress, and improving safety.

[0056] Furthermore, the main cooling section 202 can extend spirally around the clearance hole 206, such as... Figure 3 As shown, the main cooling section 202 extends around the clearance hole 206 and is spiral-shaped. The main cooling section 202 includes multiple layers distributed from the inside to the outside. This allows the portion of the cooktop panel 12 located around the clearance hole 206 to dissipate heat evenly, avoiding thermal stress concentration caused by uneven heat dissipation. Moreover, when the coolant flows in the main cooling section 202, it can gradually diffuse from the inlet end to the outlet end along the extension direction of the main cooling section 202. This can prevent the cooktop panel 12 from suddenly bursting due to excessive cold shock effect caused by the large temperature difference between the coolant and the cooktop panel 12 when the coolant suddenly fills the entire cooling channel 201.

[0057] In other embodiments, the main cooling section 202 may include multiple sub-cooling sections and connecting sections. Each sub-cooling section may be formed as an annular shape extending circumferentially along the clearance hole 206. Multiple sub-cooling sections may be arranged at intervals from the inside to the outside along the radial direction of the fire hole. The connecting section may extend radially along the clearance hole 206 and sequentially connect multiple sub-cooling sections. Optionally, each sub-cooling section may be formed as a circle, square, or hexagon. The shape of each sub-cooling section may be reasonably selected according to actual needs.

[0058] Optionally, the cross-section of the cooling channel 201 can be formed as a semi-circle, square, V-shaped, or U-shaped structure, which simplifies the structure and facilitates molding. Understandably, when the cross-section of the cooling channel 201 is formed as a semi-circle or U-shaped structure, sharp corners can be avoided within the cooling channel 201, thereby reducing the fluid resistance within the cooling channel 201 and making the flow efficiency of the coolant more efficient.

[0059] In some embodiments, the distribution density of the main cooling section 202 is reduced in the radial direction along the clearance hole 206 and from the inside out. Since the temperature of the cooktop panel 12 gradually decreases in the radial direction along the clearance hole 206 and from the inside out, gradually reducing the density of the main cooling section 202 makes the arrangement of the main cooling section 202 more reasonable. This can avoid the waste of coolant and simplify the processing technology of the cooling channel 201, reducing the processing difficulty.

[0060] Here, the gradually decreasing distribution density of the main cooling section 202 means that when the main cooling section 202 is formed in a spiral shape, there are multiple intersection points between any radius of the clearance hole 206 and the main cooling section 202 distributed from the inside out. In the radial direction of the clearance hole 206 from the inside out, the distance between two adjacent intersection points gradually increases. However, when the main cooling section 202 is formed to include multiple sub-cooling sections and connecting sections, and the multiple sub-cooling sections are formed in concentric circles, the distance between two adjacent sub-cooling sections gradually increases in the radial direction of the clearance hole 206 from the inside out.

[0061] In some embodiments, the integrated stove 100 may include multiple burners. Correspondingly, the heat-conducting plate may also have multiple clearance holes 206, and each clearance hole 206 corresponds to one burner. The cooling channel 201 may include multiple main cooling sections 202, each corresponding to one clearance hole 206. Each main cooling section 202 may have a coolant outlet 205 at its outlet end. The cooling channel 201 may also include a connecting section 203, one end of which is connected to the inlet end of all main cooling sections 202, and the other end of which may have a coolant inlet 204. In other words, multiple main cooling sections 202 may share the same coolant inlet 204, meaning that the coolant entering multiple main cooling sections 202 all comes from the same coolant inlet 204. The inlet end of each main cooling section 202 is connected to the coolant inlet 204 through the connecting section 203. This helps to save the amount of liquid delivery pipe used to connect the liquid storage device 21 and the cooling channel 201.

[0062] like Figure 3As shown, the integrated stove 100 may include two burners. Both the cooktop panel 12 and the heat-conducting plate have two clearance holes 206. The burners are positioned corresponding to the clearance holes 206. The cooling channel 201 on the heat-conducting plate includes two main cooling sections 202, which are respectively arranged around the two clearance holes 206. Each main cooling section 202 may have a coolant outlet 205 at its outlet end. The cooling channel 201 may also include a connecting section 203, which may be located in the middle of the two clearance holes 206. The connecting section 203 can extend in a direction perpendicular to the line connecting the centers of the two clearance holes 206. One end of the connecting section 203 forms a coolant inlet 204, and the other end of the connecting section 203 is smoothly connected to the inlet ends of the two main cooling sections 202 respectively. This ensures that the distance between the connecting section 203 and the two main cooling sections 202 is the same, the distribution is more reasonable, and it is also conducive to ensuring that the flow distance of the coolant from the coolant inlet 204 to each coolant outlet 205 is equal, thereby ensuring uniform heat dissipation on the stove panel 12.

[0063] In some embodiments, the liquid inlet end of the main cooling section 202 is farther from the center of the clearance hole 206 than the liquid outlet end of the main cooling section 202, such as... Figure 3 As shown, the liquid inlet of the main cooling section 202 can be located at the end of the outermost ring of the main cooling section 202, and the liquid outlet of the main cooling section 202 can be located at the end of the innermost ring of the main cooling section 202. This ensures that the coolant gradually diffuses from the outermost to the innermost side of the main cooling section 202, and also allows the coolant to gradually diffuse from the position of the cooktop panel 12 with the smallest temperature difference to the position with the largest temperature difference. During the diffusion process of the coolant, the temperature of the coolant rises. This can prevent the cooktop panel 12 from suddenly bursting due to an excessive temperature difference between the coolant and the cooktop panel 12 when the coolant suddenly fills the entire cooling channel 201.

[0064] In some embodiments, reference Figure 3 The integrated stove 100 may also include an air conditioning unit and a condensate collection and utilization device 4. The air conditioning unit is located inside the body 11, for example, within the housing cavity of the body 11. The condensate collection and utilization device 4 collects the condensate generated by the air conditioning unit. The condensate can be used directly as a coolant, or it can be used to cool the coolant. In other words, the condensate can be directly introduced into the cooling channel 201 to cool the stove panel 12. The condensate can also be used to exchange heat with the coolant, allowing the coolant to continuously absorb heat from the stove panel 12. This allows for the recovery and utilization of residual cooling from the air conditioning unit, which is beneficial for environmental protection and resource conservation.

[0065] Alternatively, when condensate is used to cool the coolant, the coolant can be a liquid with a cooling rate lower than that of condensate. For example, cooling oil can be selected as the coolant. This can reduce the risk of the cooktop panel 12 suddenly cracking due to excessively rapid temperature drop.

[0066] Furthermore, the air conditioning unit may include components such as evaporator 3, condenser, compressor, and fan. When the evaporator 3 is working, it can absorb heat from the air to cool it. The hot and humid air near the surface of the evaporator 3 is easily cooled and condensation is generated on the evaporator 3. The condensation collection and utilization device 4 can collect the condensation attached to the evaporator 3 and use the cooling capacity carried by the condensation to directly or indirectly dissipate heat from the stove panel 12, thereby realizing the recovery and utilization of the residual cooling of the air conditioning unit, which is beneficial to environmental protection and resource conservation.

[0067] In some embodiments, the condensate constitutes a coolant, meaning that the condensate can flow directly into the cooling channel 201 to cool the cooktop panel 12. The condensate collection and utilization device 4 may include a condensate pump 42 and a condensate collector 41. Specifically, the inner side of the condensate collector 41 defines a collection chamber, and the condensate generated on the evaporator 3 is collected in the collection chamber by the condensate collector 41. For example, the condensate collector 41 may be a drip tray or other containers or devices that can be used to collect condensate. The condensate pump 42 can drive the condensate to circulate between the cooling channel 201 and the collection chamber, so that the cooling capacity of the condensate can be used to cool the cooktop panel 12.

[0068] It should be noted that the condensate collector 41 may be equipped with a drain pipe 43, which can be connected to the household drain pipe. A drain valve 44 may be installed at the drain pipe 43 to control the connection between the drain pipe 43 and the drain pipe. Since the condensate carries a limited amount of cold energy, after the condensate directly absorbs heat from the cooktop panel 12 as a coolant for a period of time, it will no longer have the ability to absorb heat. In addition, since condensate is continuously produced, the drain valve 44 can be opened to drain the condensate when the temperature of the condensate reaches a certain value or when it no longer has the ability to absorb heat.

[0069] For example, two collection chambers can be provided in the condensate collector 41, namely a first collection chamber and a second collection chamber. The first collection chamber is used to directly collect condensate from the evaporator 3. The first and second collection chambers can be connected on and off, that is, a water outlet valve is provided between the first and second collection chambers. The walls of the first and second collection chambers can be made of heat-insulating material. The second collection chamber can form a circulation connection with the cooling channel 201. Furthermore, the second collection chamber can be provided with a drain pipe 43, which is connected to the drain pipe. The drain pipe 43 can be provided with a drain valve 44. During operation, condensate from the evaporator 3 is collected in the first collection chamber, with the outlet valve kept closed. When the condensate collected in the first collection chamber reaches a set amount, the outlet valve is opened to allow the condensate to flow into the second collection chamber, and then the outlet valve is closed. At this time, the condensate is driven by the condensate pump 42 to circulate between the cooling channel 201 and the second collection chamber. During the circulation of condensate in the second collection chamber, the first collection chamber can also simultaneously collect condensate from the evaporator 3, and there is no heat exchange between the condensate in the first and second collection chambers. When the condensate in the second collection chamber reaches a set temperature or is determined to lack heat absorption capacity, the drain valve 44 can be opened to drain all the condensate in the second collection chamber into the drain pipe. After the second collection chamber is emptied, the drain valve 44 is closed and the outlet valve is opened to discharge the condensate collected in the first collection chamber into the second collection chamber. The condensate pump 42 is controlled to drive the new condensate to circulate between the cooling channel 201 and the second collection chamber to absorb the heat of the stove panel 12. By circulating in this way, the stable operation of the stove panel 12 cooling system and the timely discharge of condensate can be achieved.

[0070] In other embodiments, reference is made to... Figure 3 The condensate can be used to cool the coolant, which can be cooling oil. This avoids excessive temperature difference between the condensate and the cooktop panel 12 when the condensate is directly introduced into the cooling channel 201, thus preventing the cooktop panel 12 from cracking due to excessive cold shock. The heat dissipation assembly 2 may also include: a liquid storage device 21, a coolant pump 23, and a heat exchange device 22. The liquid storage device 21 has a liquid storage chamber 211, which is connected to the cooling channel 201. The coolant pump 23 drives the coolant to circulate between the liquid storage chamber 211 and the cooling channel 201.

[0071] The heat exchange device 22 is located within the liquid storage chamber 211, and a heat exchange channel 221 is defined within the heat exchange device 22. The condensate collection and utilization device 4 may include a condensate collector 41 and a condensate pump 42. The condensate collector 41 has a collection chamber for collecting condensate, and the collection chamber and the heat exchange channel 221 are in cyclic communication. The condensate pump 42 is used to drive the condensate to circulate between the heat exchange channel 221 and the collection chamber. Understandably, when the collection chamber and the heat exchange channel 221 are configured to circulate, that is, when the condensate can circulate between the heat exchange channel 221 and the collection chamber, the condensate collector 41 may be provided with a drain pipe 43, which may be connected to a household drain pipe. A drain valve 44 may be provided at the drain pipe 43, and the drain valve 44 is used to control the opening and closing of the drain pipe 43 and the drain pipe. Since the cooling capacity carried by the condensate is limited, after the condensate and coolant exchange heat for a period of time, the condensate will no longer have the ability to absorb heat. In addition, since condensate is continuously produced, the drain valve 44 can be opened to drain the condensate when the temperature of the condensate reaches the set value or when it no longer has the ability to absorb heat.

[0072] For example, the condensate collector 41 can define two collection chambers, namely a first collection chamber and a second collection chamber. The first collection chamber can directly collect the condensate generated on the evaporator 3. The walls of the first and second collection chambers can be made of heat-insulating material. The second collection chamber can form a circulating connection with the heat exchange channel 221. The first and second collection chambers can be connected on and off, that is, a water outlet valve is provided between the first and second collection chambers. Furthermore, the second collection chamber can be provided with a drain pipe 43, which is connected to the drain pipe. The drain pipe 43 can be provided with a drain valve 44. During operation, condensate from the evaporator 3 is collected in the first collecting chamber, with the outlet valve kept closed. When the condensate collected in the first collecting chamber reaches a set amount, the outlet valve is opened to allow the condensate to flow into the second collecting chamber, and then the outlet valve is closed. At this point, the condensate can be circulated between the second collecting chamber and the heat exchange channel 221 by the condensate pump 42. During the circulation of condensate in the second collecting chamber, the first collecting chamber can also simultaneously collect condensate from the evaporator 3, and there is no heat exchange between the condensate in the first and second collecting chambers. When the condensate in the second collecting chamber reaches a set temperature or is determined to lack heat absorption capacity, the drain valve 44 can be opened to drain all the condensate in the second collecting chamber into the drain pipe. After the second collection chamber is emptied, the drain valve 44 is closed and the outlet valve is opened to discharge the condensate collected in the first collection chamber into the second collection chamber. The condensate pump 42 is controlled to drive the new condensate to circulate between the heat exchange channel 221 and the second collection chamber to absorb the heat of the stove panel 12. By circulating in this way, the stable operation of the stove panel 12 cooling system and the timely discharge of condensate can be achieved.

[0073] Or, such as Figure 3 As shown, the collection chamber and the heat exchange channel 221 are connected in one direction. At this time, the condensate pump 42 is used to transport the condensate collected in the collection chamber to the heat exchange channel 221. The condensate collection and utilization device 4 also includes a drain pipe 43, which is adapted to be connected to the heat exchange channel 221. The drain pipe 43 can be connected to the end of the heat exchange channel 221 away from the collection chamber. A drain valve 44 is provided in the drain pipe 43. In this way, when the heat absorption capacity of the condensate is saturated, the drain valve 44 can be opened to drain the condensate that no longer has the heat absorption capacity, so that the new condensate collected later can enter the heat exchange channel 221 and exchange heat with the coolant. Furthermore, it should be noted that when the collection chamber and heat exchange channel 221 are in unidirectional communication, meaning that condensate can only flow from the collection chamber of the condensate collector 41 to the heat exchange channel 221, the condensate pump 42 can be controlled to start periodically. After driving the condensate in the collection chamber into the heat exchange channel 221, the condensate pump 42 is turned off, thereby isolating the connection between the collection chamber and the heat exchange channel 221 and preventing condensate backflow. When the condensate entering the heat exchange channel 221 exchanges heat with the coolant for a period of time and no longer has the ability to absorb heat, the drain valve 44 is opened to discharge the condensate in the heat exchange channel 221 from the drain pipe 43. During this process, the collection chamber can also collect new condensate simultaneously. Then, the drain valve 44 is closed, and the condensate pump 42 is turned on to drive the newly collected condensate in the collection chamber into the heat exchange channel 221. Thus, it can be ensured that the collected condensate can be continuously used to cool the coolant.

[0074] In some embodiments, the integrated stove 100 may further include: a first temperature detection device (not shown), a second temperature detection device (not shown), and a control module (not shown). Specifically, the first temperature detection device may be used to detect the temperature of the stove panel 12, and the first temperature detection device may be located near the clearance hole 206 on the stove panel 12; the second temperature detection device may be used to detect the temperature of the condensate in the heat exchange channel 221, in which case the second temperature detection device is located in the heat exchange channel 221; or, the second temperature detection device may also be used to detect the temperature of the condensate in the condensate collector 41, in which case the second temperature detection device may be located in the collection chamber, and when the condensate collector 41 has a first collection chamber and a second collection chamber, the first collection chamber is used to collect the condensate of the evaporator 3, and the second collection chamber is circulatedly connected to the cooling channel 201 or the heat exchange channel 221, the second temperature detection device is located in the second collection chamber.

[0075] The control module can communicate with the coolant pump 23, the second temperature detection device, the first temperature detection device, the condensate pump 42, and the condensate collector 41 or the drain valve 44 respectively. The control module controls the operating status of the coolant pump 23, the condensate pump 42, the condensate collector 41 or the drain valve 44 according to the detection values ​​of the first temperature detection device and / or the second temperature detection device.

[0076] In a specific example, the heat dissipation component 2 may further include a heat dissipation fan (not shown). For example, the heat dissipation fan may be configured to have its air outlet directly facing the cooktop panel 12 to directly remove heat from the cooktop panel 12; or, the heat dissipation fan may be configured to have its air outlet facing the heat guide plate to cool the coolant in the cooling channel 201. In this way, the heat dissipation and cooling efficiency of the cooktop panel 12 can be further improved.

[0077] The following is combined with Figure 6 and Figure 7 A control method for an integrated stove 100 according to a second aspect embodiment of the present invention is described.

[0078] According to a control method for an integrated stove 100 according to a second aspect of the present invention, the integrated stove 100 may be an integrated stove 100 according to the above-described embodiments of the present invention, wherein a condensate pump 42 is used to drive condensate to circulate between a heat exchange channel 221 and a cooling channel 201.

[0079] The control method includes the following steps: turning on the integrated stove body; collecting the temperature of the stove panel; determining that the temperature of the stove panel is greater than a first temperature setting value; and turning on the coolant pump and the condensate pump.

[0080] Specifically, the integrated stove body 1 is first turned on and started. Then, the first temperature detection device detects the temperature of the position near the clearance hole 206 of the stove panel 12. The first temperature detection device feeds back the detection result (i.e., the real-time temperature value of the stove panel 12) to the control module. The control module compares the detection result of the first temperature detection device with the first temperature set value. When the control module determines that the detection value of the first temperature detection device is greater than the first temperature set value, it means that the temperature of the stove panel 12 is too high and needs to be cooled down. At this time, the control module controls the condensate pump 42 and the coolant pump 23 to start. The coolant pump 23 starts to drive the coolant to circulate between the cooling channel 201 and the storage chamber 211 of the storage device 21. The coolant absorbs the heat of the stove panel 12. At the same time, the condensate pump 42 drives the condensate to circulate between the condensate collector 41 and the heat exchange channel 221 of the heat exchange device 22. The condensate exchanges heat with the coolant at the heat exchange device 22, thereby cooling the coolant. When the control module determines that the detection value of the first temperature detection device is less than or equal to the first temperature setting value, it means that the stove panel 12 does not need to be cooled down at this time, and the coolant pump 23 and condensate pump 42 can be controlled to remain in the off state.

[0081] Here, the first temperature setting value T0 can be in the range of 70℃-90℃. For example, the first temperature setting value T0 can be 70℃, 75℃, 78℃, 80℃, 85℃ or 90℃. This avoids the energy waste caused by turning on the condensate pump 42 and coolant pump 23 when the first temperature setting value T0 is set too low, such as less than 70℃, because the thermal stress inside the stove panel 12 is insufficient to cause the stove panel 12 to crack. It also avoids the thermal stress inside the stove panel 12 becoming too high or even cracking before the stove panel 12 has had time to cool down. As a result, the starting time of the coolant pump 23 and condensate pump 42 is more scientific and reasonable, avoiding the situation of not starting in time or starting too late.

[0082] According to the control method of the integrated stove 100 of the present invention, when the temperature of the stove panel 12 is greater than the first temperature setting value, the coolant pump 23 and the condensate pump 42 are turned on, which can dissipate heat from the stove panel 12 in time and reduce the temperature, thereby reducing the risk of burns or breakage of the stove panel 12 after accidental contact and improving safety.

[0083] Furthermore, the control method also includes: collecting the temperature of the condensate in the collection chamber; determining that the difference between the temperature of the stove panel and the temperature of the condensate is greater than a first set temperature difference; and controlling the speed of the coolant pump to decrease to a set speed.

[0084] Specifically, after the integrated stove body 1 is turned on, the second temperature detection device detects the temperature of the condensate in the collection chamber. The second temperature detection device can feed back the temperature of the condensate to the control module. The control module calculates the temperature difference ΔT between the condensate and the stove panel 12, and compares this difference ΔT with the first set temperature difference T1. When the control module determines that the temperature difference between the stove panel 12 and the condensate is greater than the first set temperature difference, in order to prevent the coolant from causing a cold shock to the stove panel 12, the control module can control the coolant pump 23 to reduce its speed to a set speed, for example, the minimum speed. When the control module determines that the temperature difference between the stove panel 12 and the condensate is less than or equal to the first set temperature difference, the control module can control the coolant pump 23 to maintain its original speed to ensure normal heat dissipation.

[0085] Here, the range of the first set temperature difference T1 can be 40℃-65℃. For example, the value of the first set temperature difference can be 40℃, 45℃, 50℃, 55℃, 60℃, or 65℃. This avoids both setting the first set temperature difference T1 too small, such as less than 40℃, which would cause unnecessary speed reduction of the coolant pump 23 and reduce the heat dissipation efficiency of the cooktop panel 12, and setting the first set temperature difference T1 too high, such as greater than 65℃, which would cause the condensate to form a large cold shock on the cooktop panel 12 through the coolant and cause the cooktop panel 12 to crack. Thus, the speed reduction time of the coolant pump 23 and the condensate pump 42 is more scientific and reasonable, avoiding situations where the speed reduction is not timely or too early. Optionally, when the control module controls the coolant pump 23 to reduce its speed, the control module can also simultaneously control the condensate pump 42 to reduce its speed.

[0086] In some embodiments, the control method may further include: collecting the temperature of the condensate in the collection chamber; determining that the difference between the temperature of the cooktop panel and the temperature of the condensate is less than a second set temperature difference, wherein the second set temperature difference is less than a first set temperature difference; controlling the coolant pump and the condensate pump to stop; and controlling the condensate collector to discharge the condensate.

[0087] Specifically, after the integrated stove body 1 is turned on, the second temperature detection device detects the temperature of the condensate in the collection chamber. The second temperature detection device can feed back the temperature of the condensate to the control module. The control module calculates the temperature difference ΔT between the stove panel 12 and the condensate temperature, and compares this difference ΔT with the second set temperature difference T2. When the control module determines that the temperature difference ΔT between the stove panel 12 and the condensate temperature is less than the second set temperature difference T2, it indicates that the heat absorption capacity of the coolant has been saturated and it can no longer cool the coolant. The control module can then control the coolant pump 23 and the condensate pump 42 to stop, and control the condensate collector 41 to discharge the condensate into the drain pipe. When the control module determines that the temperature difference ΔT between the stove panel 12 and the condensate temperature is greater than or equal to the second set temperature difference T2, it indicates that there is still a temperature difference between the condensate and the stove panel 12, and the condensate can continue to absorb heat. The control module can then control the coolant pump 23 and the condensate pump 42 to maintain their original speeds to ensure normal heat dissipation.

[0088] Here, the range of the second set temperature difference T2 can be 0.5℃-2℃. For example, the value of the second set temperature difference T2 can be 0.5℃, 0.8℃, 1℃, 1.5℃, 1.7℃ or 2℃. This avoids the energy waste caused by the condensate pump 42 and coolant pump 23 continuing to operate when the second set temperature difference T2 is set too small, such as less than 0.5℃, because the heat absorption capacity of the condensate is close to saturation. It also avoids the situation where the condensate pump 42 and coolant pump 23 are stopped too early when the second set temperature difference is set too high, such as greater than 2℃, so that the cooling capacity of the condensate is not fully utilized. Thus, the stopping time of the coolant pump 23 and condensate pump 42 is more scientific and reasonable, avoiding the situation of untimely or premature stopping.

[0089] In some embodiments, the control method further includes: determining that the temperature decay value of the cooktop panel within a preset time period is greater than a set decay value; and controlling the coolant pump to reduce its rotation speed.

[0090] Specifically, after the integrated stove body 1 is turned on, the first temperature detection device detects the temperature of the position near the clearance hole 206 of the stove panel 12. The first temperature detection device feeds back the detection result (i.e., the real-time temperature value of the stove panel 12) to the control module. The control module calculates the temperature decay value of the stove panel 12 within a predetermined time and compares the calculated decay value with the set decay value. If the temperature decay value of the stove panel 12 within the predetermined time is greater than the set decay value, it means that the stove panel 12 is cooling down too fast, which poses a risk of cracking. The control module can control the coolant pump 23 to reduce the speed to reduce the cooling rate of the stove panel 12. If the temperature decay value of the stove panel 12 within the predetermined time is less than or equal to the set decay value, it means that the cooling rate of the stove panel 12 is moderate. At this time, the control module can control the coolant pump 23 to maintain the speed to maintain the cooling rate of the stove panel 12.

[0091] Here, the range of the predetermined duration t can be 5s-20s. For example, the predetermined duration t can be 5s, 10s, 15s or 20s. The range of the set attenuation value can be 10℃-30℃. For example, the set attenuation value can be 10℃, 15℃, 20℃, 25℃ or 30℃.

[0092] The following will refer to Figures 1-7 An integrated stove 100 according to a specific embodiment of the present invention is described.

[0093] Example 1,

[0094] The integrated stove 100 in this embodiment includes: an integrated stove body 1, a heat dissipation component 2, an air conditioning device, a condensate collection and utilization device 4, a first temperature detection device, a second temperature detection device, and a control module.

[0095] The integrated stove body 1 includes a main body 11 and a cooktop. The main body 11 is roughly cubic in shape and defines a receiving cavity with an opening on the upper side. The cooktop is located on top of the receiving cavity, and the top of the cooktop has a mounting opening suitable for mounting the cooktop panel 12. The cooktop panel 12 is inserted into the mounting opening and remains flush with the perimeter of the top wall of the main body 11. The cooktop panel 12 is made of tempered glass. The cooktop has two burners.

[0096] The heat dissipation assembly 2 includes: a heat-conducting element 20, a liquid storage device 21, a coolant pump 23, and a heat exchange device 22. The heat-conducting element 20 can be formed as a heat-conducting plate, which is located on the top of the body 11 and on the bottom surface of the cooktop panel 12. The heat-conducting element 20 is in contact with the cooktop panel 12. A cooling groove is formed on the side of the heat-conducting plate facing the cooktop panel 12. The inner wall of the cooling groove and the bottom surface of the cooktop panel 12 define a cooling flow channel 201. Two clearance holes 206 are formed on the heat-conducting plate, and the two clearance holes 206 correspond one-to-one with the two burners. The cooling channel 201 may include a connecting section 203 and two main cooling sections 202 respectively distributed on the outer periphery of the two clearance holes 206. The main cooling sections 202 extend around the clearance holes 206 and are formed in a spiral shape. The main cooling sections 202 include multiple layers distributed from the inside to the outside. In the radial direction from the inside to the outside along the clearance holes 206, the distribution density of the main cooling sections 202 decreases. Each main cooling section 202 has a coolant outlet 205 at its outlet end. One end of the connecting section 203 is connected to the inlet end of both main cooling sections 202, and the other end of the connecting section 203 has a coolant inlet 204.

[0097] A liquid storage device 21 is used to store coolant. A storage chamber 211 is defined within the liquid storage device 21, which has an inlet and an outlet, both of which are connected to the storage chamber 211. The coolant inlet 204 of the cooling channel 201 can be connected to the outlet of the liquid storage device 21, and the coolant outlet 205 of the cooling channel 201 is connected to the inlet of the liquid storage device 21. A coolant pump 23 is located between the coolant inlet 204 of the cooling channel 201 and the outlet of the liquid storage device 21, and can be used to drive the coolant to circulate between the storage chamber 211 and the cooling channel 201. A heat exchange device 22 is located within the storage chamber 211, and a heat exchange channel 221 is defined within the heat exchange device 22.

[0098] The air conditioning unit can be installed in the housing cavity of the unit 11. The air conditioning unit includes components such as evaporator 3, condenser, compressor, and fan. When the evaporator 3 is working, the evaporator 3 can absorb heat from the air to cool it. The humid and hot air near the surface of the evaporator 3 is easily cooled and condensed on the evaporator 3.

[0099] The condensate collection and utilization device 4 includes a condensate collector 41 and a condensate pump 42. The condensate collector 41 and the heat exchange channel 221 are connected in a loop. The condensate pump 42 is located between the condensate collector 41 and the heat exchange device 22. The condensate collector 41 has two collection chambers, namely a first collection chamber and a second collection chamber. The first collection chamber is used to directly collect condensate from the evaporator 3. A drain valve is provided between the first collection chamber and the second collection chamber. The walls of the first collection chamber and the second collection chamber are made of heat-insulating material. The second collection chamber can be connected in a loop with the heat exchange channel 221. The second collection chamber is provided with a drain pipe 43, which is connected to a drain pipe. The drain pipe 43 can be provided with a drain valve 44. During operation, condensate from the evaporator 3 is collected in the first collection chamber, with the outlet valve kept closed. When the condensate collected in the first collection chamber reaches a set amount, the outlet valve is opened to allow the condensate to flow into the second collection chamber, and then the outlet valve is closed. At this time, the condensate is driven by the condensate pump 42 to circulate between the heat exchange channel 221 and the second collection chamber. During the circulation of condensate in the second collection chamber, the first collection chamber can also simultaneously collect condensate from the evaporator 3, and there is no heat exchange between the condensate in the first and second collection chambers. When the condensate in the second collection chamber reaches a set temperature or is determined to lack heat absorption capacity, the drain valve 44 can be opened to drain all the condensate in the second collection chamber into the drain pipe. After the second collection chamber is emptied, the drain valve 44 is closed and the outlet valve is opened to discharge the condensate collected in the first collection chamber into the second collection chamber. The condensate pump 42 is controlled to drive the new condensate to circulate between the heat exchange channel 221 and the second collection chamber to absorb the heat of the stove panel 12. By circulating in this way, the stable operation of the stove panel 12 cooling system and the timely discharge of condensate can be achieved.

[0100] The first temperature detection device is used to detect the temperature of the cooktop panel 12, and the first temperature detection device is located near the clearance hole 206 on the cooktop panel 12; the second temperature detection device is used to detect the temperature of the condensate in the heat exchange channel 221, and the second temperature detection device is located in the heat exchange channel 221; the control module communicates with the first temperature detection device, the second temperature detection device, the coolant pump 23, the condensate pump 42, and the condensate collector 41 or the drain valve 44 respectively, and the control module controls the operating status of the coolant pump 23, the condensate pump 42, the condensate collector 41 or the drain valve 44 according to the detection values ​​of the first temperature detection device and the second temperature detection device.

[0101] The control method of the integrated stove 100 in this embodiment is as follows:

[0102] First, control the integrated cooker body 1 to start running. Then, the first temperature detection device detects the temperature at the position of the adjacent avoidance hole 206 on the cooker panel 12. The first temperature detection device feeds back the detection result (i.e., the real-time temperature value of the cooker panel 12) to the control module. The control module compares the detected value of the first temperature detection device with the first temperature setting value. When the control module determines that the detected value of the first temperature detection device is greater than the first temperature setting value, it indicates that the temperature of the cooker panel 12 is relatively high at this time and heat dissipation and cooling are required. At this time, the control module controls the coolant pump 23 and the condensate pump 42 to start. The coolant pump 23 starts to drive the coolant to circulate between the liquid storage device 21 and the cooling channel 201, and the coolant absorbs the heat of the cooker panel 12. At the same time, the condensate pump 42 drives the condensate to circulate between the condensate collector 41 and the heat exchange channel 221 of the heat exchange device 22, and the condensate exchanges heat with the coolant at the heat exchange device 22, thereby cooling the coolant. When the control module determines that the detected value of the first temperature detection device is less than or equal to the first temperature setting value, it indicates that the cooker panel 12 does not need to be cooled at this time, and the control module can control the coolant pump 23 and the condensate pump 42 to maintain the closed state.

[0103] During the operation of the integrated cooker 100, the second temperature detection device continuously detects the temperature of the condensate water in the collection chamber. The second temperature detection device can feed back the temperature of the condensate water to the control module. The control module calculates the temperature difference ΔT between the cooker panel 12 and the condensate water temperature and compares this difference ΔT with the first set temperature difference T1. The first set temperature difference is 50 °C. When the control module determines that the temperature difference ΔT between the cooker panel 12 and the condensate water temperature is greater than T1, to prevent the coolant from causing a cold shock to the cooker panel 12, the control module can control the coolant pump 23 to reduce the rotational speed to the lowest rotational speed. When the control module determines that the temperature difference T2 ≤ ΔT ≤ T1 between the cooker panel 12 and the condensate water temperature, where T2 is the second set temperature difference and T2 is 1 °C, the control module can control the coolant pump 23 to maintain the original rotational speed to ensure normal heat dissipation. When the control module determines that the temperature difference ΔT between the cooker panel 12 and the condensate water temperature is less than T2, the control module can control the coolant pump 23 and the condensate pump 42 to stop and control the condensate collector 41 to drain the condensate water into the sewer pipe.

[0104] Furthermore, during the operation of the coolant pump 23 and the condensate pump 42, the control module calculates the temperature decay value of the cooktop panel 12 within a predetermined time period and compares the calculated decay value with the set decay value. If the temperature decay value of the cooktop panel 12 within the predetermined time period is greater than the set decay value, it indicates that the cooktop panel 12 is cooling down too fast, which poses a risk of cracking. In this case, the control module can control the coolant pump 23 to reduce its speed to reduce the cooling rate of the cooktop panel 12. If the temperature decay value of the cooktop panel 12 within the predetermined time period is less than or equal to the set decay value, it indicates that the cooling rate of the cooktop panel 12 is moderate. In this case, the control module can control the coolant pump 23 to maintain its speed to maintain the cooling rate of the cooktop panel 12.

[0105] Example 2,

[0106] The integrated stove 100 in this embodiment includes: an integrated stove body 1, a heat dissipation component 2, an air conditioning unit, and a condensate collection and utilization device 4.

[0107] The integrated stove body 1 includes a main body 11 and a cooktop. The main body 11 is roughly cubic in shape and defines a receiving cavity with an opening on the upper side. The cooktop is located on top of the receiving cavity, and the top of the cooktop has a mounting opening suitable for mounting the cooktop panel 12. The cooktop panel 12 is inserted into the mounting opening and remains flush with the perimeter of the top wall of the main body 11. The cooktop panel 12 is made of tempered glass. The cooktop has two burners.

[0108] The heat dissipation component 2 includes a heat-conducting element 20 and a heat dissipation fan. The heat-conducting element 20 can be formed as a heat-conducting plate, which is located on the top of the body 11 and on the bottom surface of the cooktop panel 12. The heat-conducting element 20 is in contact with the cooktop panel 12. A cooling groove is formed on the side of the heat-conducting plate facing the cooktop panel 12. The inner wall of the cooling groove and the bottom surface of the cooktop panel 12 define a cooling flow channel 201. Two clearance holes 206 are formed on the heat-conducting plate, each corresponding to one of the two burners. The cooling channel 201 may include a connecting section 203 and two main cooling sections 202 distributed on the outer periphery of the two clearance holes 206. The main cooling sections 202 extend around the clearance holes 206 and are spiral-shaped. The main cooling sections 202 include multiple layers distributed from the inside out. The distribution density of the main cooling sections 202 decreases from the inside out in the radial direction along the clearance holes 206. Each main cooling section 202 has a coolant outlet 205 at its outlet end. One end of the connecting section 203 is connected to the inlet end of both main cooling sections 202, and the other end of the connecting section 203 has a coolant inlet 204. A cooling fan is installed on the body 11, and the air outlet of the cooling fan faces the heat-conducting plate.

[0109] The air conditioning unit can be installed in the housing cavity of the unit 11. The air conditioning unit includes components such as evaporator 3, condenser, compressor, and fan. When the evaporator 3 is working, the evaporator 3 can absorb heat from the air to cool it. The humid and hot air near the surface of the evaporator 3 is easily cooled and condensed on the evaporator 3.

[0110] The condensate collection and utilization device 4 includes a condensate collector 41 and a condensate pump 42. The condensate collector 41 and the cooling channel 201 are connected in a loop. The condensate pump 42 is located between the condensate collector 41 and the heat exchange device 22. The condensate collector 41 has two collection chambers, namely a first collection chamber and a second collection chamber. The first collection chamber is used to directly collect condensate from the evaporator 3. A drain valve is provided between the first collection chamber and the second collection chamber. The walls of the first collection chamber and the second collection chamber are made of heat-insulating material. The second collection chamber can be connected in a loop with the cooling channel 201. The second collection chamber is provided with a drain pipe 43, which is connected to a drain pipe. The drain pipe 43 can be provided with a drain valve 44. During operation, condensate from the evaporator 3 is collected in the first collection chamber, with the outlet valve kept closed. When the condensate collected in the first collection chamber reaches a set amount, the outlet valve is opened to allow the condensate to flow into the second collection chamber, and then the outlet valve is closed. At this time, the condensate is driven by the condensate pump 42 to circulate between the cooling channel 201 and the second collection chamber. During the circulation of condensate in the second collection chamber, the first collection chamber can also simultaneously collect condensate from the evaporator 3, and there is no heat exchange between the condensate in the first and second collection chambers. When the condensate in the second collection chamber reaches a set temperature or is determined to lack heat absorption capacity, the drain valve 44 can be opened to drain all the condensate in the second collection chamber into the drain pipe. After the second collection chamber is emptied, the drain valve 44 is closed and the outlet valve is opened to discharge the condensate collected in the first collection chamber into the second collection chamber. The condensate pump 42 is controlled to drive the new condensate to circulate between the cooling channel 201 and the second collection chamber to absorb the heat of the stove panel 12. By circulating in this way, the stable operation of the stove panel 12 cooling system and the timely discharge of condensate can be achieved.

[0111] Example 3,

[0112] The structure of the integrated stove 100 in this embodiment is largely the same as that of the integrated stove 100 in Embodiment 1, and its control method is also similar. The difference lies in that the main cooling section 202 in this embodiment may include multiple sub-cooling sections and connecting sections. Each sub-cooling section may be formed as a ring extending circumferentially along the clearance hole 206. The multiple sub-cooling sections may be arranged at intervals from the inside to the outside along the radial direction of the fire passage hole. The connecting section may extend radially along the clearance hole 206 and sequentially connect the multiple sub-cooling sections. Here, the heat dissipation component 2 in this embodiment may also include a heat dissipation fan, which is disposed on the body 11, and the air outlet of the heat dissipation fan is disposed towards the heat guide plate.

[0113] Example 4,

[0114] The structure of the integrated stove 100 in this embodiment is roughly the same as that of the integrated stove 100 in Embodiment 2. The difference is that the main cooling section 202 in this embodiment may include multiple sub-cooling sections and connecting sections. Each sub-cooling section may be formed as a ring extending circumferentially along the clearance hole 206. Multiple sub-cooling sections may be arranged at intervals from the inside to the outside along the radial direction of the fire hole.

[0115] Example 5,

[0116] The structure of the integrated stove 100 in this embodiment is roughly the same as that of the integrated stove 100 in Embodiment 1. The difference is that in this embodiment, the collection chamber of the condensate collector 41 and the heat exchange channel 221 of the heat exchange device 22 are connected in one direction. At this time, the condensate pump 42 is used to transport the condensate in the collection chamber to the heat exchange channel 221. The condensate collection and utilization device 4 also includes a drain pipe 43, which is adapted to be connected to the heat exchange channel 221. The drain pipe 43 can be connected to the end of the heat exchange channel 221 away from the collection chamber. A drain valve 44 is provided in the drain pipe 43. In this way, when the heat absorption capacity of the condensate is saturated, the drain valve 44 can be opened to drain the condensate that no longer has the heat absorption capacity, so that the new condensate collected later can enter the heat exchange channel 221 and exchange heat with the coolant. Furthermore, it should be noted that when the collection chamber and heat exchange channel 221 are in unidirectional communication, meaning that condensate can only flow from the collection chamber of the condensate collector 41 to the heat exchange channel 221, the condensate pump 42 can be controlled to start periodically. After driving the condensate in the collection chamber into the heat exchange channel 221, the condensate pump 42 is turned off, thereby isolating the connection between the collection chamber and the heat exchange channel 221 and preventing condensate backflow. When the condensate entering the heat exchange channel 221 exchanges heat with the coolant for a period of time and no longer has the ability to absorb heat, the drain valve 44 is opened to discharge the condensate in the heat exchange channel 221 from the drain pipe 43. During this process, the collection chamber can also collect new condensate simultaneously. Then, the drain valve 44 is closed, and the condensate pump 42 is turned on to drive the newly collected condensate in the collection chamber into the heat exchange channel 221. Thus, it can be ensured that the collected condensate can be continuously used to cool the coolant.

[0118] The structure of the integrated stove 100 in this embodiment is roughly the same as that in the integrated stove 100 in embodiment two. The difference is that in this embodiment, the collection chamber of the condensate collector 41 and the cooling channel 201 of the heat-conducting plate are connected in one direction. At this time, the condensate pump 42 is used to transport the condensate in the collection chamber to the cooling channel 201. The condensate collection and utilization device 4 also includes a drain pipe 43, which is adapted to be connected to the cooling channel 201. The drain pipe 43 can be connected to the end of the cooling channel 201 away from the collection chamber. A drain valve 44 is provided in the drain pipe 43.

Furthermore, it should be noted that when the collection chamber and cooling channel 201 are in one-way communication, meaning that condensate can only flow from the collection chamber of the condensate collector 41 to the cooling channel 201, the condensate pump 42 can be controlled to start periodically. After driving the condensate in the collection chamber into the cooling channel 201, the condensate pump 42 is turned off, thereby isolating the connection between the collection chamber and the cooling channel 201 and preventing condensate backflow.

Then, the drain valve 44 is closed, and the condensate pump 42 is turned on to drive the newly collected condensate in the collection chamber into the cooling channel 201. Thus, it can be ensured that the collected condensate can be continuously used to cool the coolant.
