[0034] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0035] As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , in one embodiment, a heat-generating and heat-exchanging device 10 is provided, comprising a temperature regulating component 100, a heat exchanger 200, a heating element 300 and a self-priming pump 410. The temperature regulating component 100 is provided with a first cooked water inlet, a second cooked water inlet and a cooked water outlet which are interconnected. The ratio of the flow rate of the first cooked water inlet to the flow rate of the second cooked water inlet is adjustable. The heat exchanger 200 is provided with a cold water inlet 210, a cold water outlet 220, a hot water inlet 230 and a hot water outlet 240. The hot water outlet 240 is connected to the first cooked water inlet. The heating element 300 is provided with a first water inlet and a first water outlet, the first water inlet is connected to the cold water outlet 220, and the first water outlet is connected to both the second cooked water inlet and the hot water inlet 230. The self-priming pump 410 is provided with a water inlet end and a water outlet end, and the water outlet end is connected to both the first water inlet and the cold water inlet 210.

[0036] When the heating and heat exchange device 10 in the above embodiment is used, the self-priming pump 410 is connected to the water purifier, and the self-priming pump 410 pumps part of the pure water provided by the water purifier to the cold water inlet 210, and is discharged from the cold water outlet 220 after heat exchange, and is combined with another part of the pure water provided by the water purifier and then transported to the heating element 300. The heating element 300 heats the pure water to a boiling state and forms hot water. At this time, the hot water discharged from the first water outlet of the heating element 300 is divided, and part of the hot water is directly transported to the second cooked water inlet, and the other part of the hot water is transported to the hot water inlet 230, and is heat exchanged with the pure water in the heat exchanger 200 to form low-temperature cooked water after cooling. The low-temperature cooked water is discharged from the hot water outlet 240 to the first cooked water inlet, and the low-temperature cooked water and the hot water are mixed in proportion in the temperature adjustment component 100 to form the target temperature cooked water, and are discharged from the cooked water outlet for user use. The heating element 300 in the present application can provide hot water for the temperature adjustment component 100, and the heat exchanger 200 can provide low-temperature cooked water for the temperature adjustment component 100. When the user needs to take the target temperature cooked water, the temperature adjustment component 100 is controlled to adjust the flow rate of the first cooked water inlet and the flow rate of the second cooked water inlet to the corresponding ratio, and the low-temperature cooked water and hot water of the corresponding ratio are mixed in the cooked water outlet to the target temperature cooked water, without waiting for a long time, and the flow rate at the cooked water outlet is large, which improves the user's experience. At the same time, the cold water outlet 220 and the hot water inlet 230 are indirectly connected in series, that is, the cold water channel in the heat exchanger 200 and the hot water channel in the heat exchanger 200 are connected at intervals, and the cooked water outlet is located on the same water flow path, ensuring that when the heat exchange device 10 is first introduced with pure water, the air in the heat exchange device 10 can be discharged from the cooked water outlet along the water flow path, thereby ensuring that the pure water and hot water in the heat exchanger 200 can fully exchange heat, thereby ensuring the temperature accuracy of the cooked water discharged from the cooked water outlet. In addition, the heating and heat exchange device 10 is designed as a separate module, which can adapt to different water purifier models. There is no need to change or redesign the water purifier, which reduces the upgrade cost and improves the practicality of the heating and heat exchange device 10.

[0037] It should be noted that the temperature regulating component 100 can be set to any valve structure in the prior art that can adjust the flow ratio of the two water inlets. Specifically in this embodiment, the ratio of the flow rate of the first cooked water inlet and the flow rate of the second cooked water inlet is adjustable, and can be adjusted by a regulating valve, for example, by moving the position of the valve body in the regulating valve, so that the flow rate of one of the first cooked water inlet and the second cooked water inlet increases while the flow rate of the other decreases accordingly. In other embodiments, the ratio of the flow rate of the first cooked water inlet and the flow rate of the second cooked water inlet is adjustable, and can also be adjusted by two regulating valves, for example, by using two regulating valves to respectively adjust the flow rate of the first cooked water inlet and the flow rate of the second cooked water inlet.

[0038] As shown in Fig. 5 and Fig. 6, the temperature adjustment component 100 further includes a two-inlet-one-outlet solenoid valve 110 and a first waterway plate 120 provided with a first cooked water inlet, a second cooked water inlet and a cooked water outlet. The two-inlet-one-outlet solenoid valve 110 is installed on the first waterway plate 120, and connects the first cooked water inlet, the second cooked water inlet and the cooked water outlet accordingly. The two-inlet-one-outlet solenoid valve 110 is used to adjust the ratio of the flow rate of the first cooked water inlet to the flow rate of the second cooked water inlet.

[0039] As shown in FIG. 5 , optionally, a first auxiliary flow channel 250 is provided on the heat exchanger 200 , one end of the first auxiliary flow channel 250 is communicated with the hot water outlet 240 , and the other end of the first auxiliary flow channel 250 is communicated with the first cooked water inlet.

[0040] Specifically in this embodiment, the heating and heat exchange device 10 further includes a transfer waterway plate 510, which is mounted on the heat exchanger 200 and connects the hot water outlet 240 and the end of the first auxiliary flow channel 250 away from the first waterway plate 120. In this way, the transfer waterway plate 510 and the first auxiliary flow channel 250 can replace the connecting pipes, making the layout of the heating and heat exchange device 10 more compact, while also reducing the use of connecting pipes, thereby reducing the production cost of the heating and heat exchange device 10.

[0041] As shown in FIG. 1 and FIG. 5 , in one embodiment, there are at least two heat exchangers 200, and each heat exchanger 200 is connected in series. Thus, by connecting multiple heat exchangers 200 in series, the heat exchange path length between pure water and hot water is increased, thereby being able to obtain cooked water with a lower temperature, and the temperature adjustment component 100 has a larger adjustment range for the cooked water temperature, thereby improving the practicality of the heat exchange device 10.

[0042] As shown in FIG. 1 and FIG. 5 , optionally, each heat exchanger 200 is provided with at least one second auxiliary flow channel 260. The heat exchanging device 10 further includes at least one second waterway plate 520. The cold water outlet 220 of the heat exchanger 200 is connected to the cold water inlet 210 of the adjacent heat exchanger 200, and the hot water outlet 240 of the heat exchanger 200 is connected to the hot water inlet 230 of the adjacent heat exchanger 200 through the second waterway plate 520 and the second waterway plate 520.

[0043] Specifically in this embodiment, each heat exchanger 200 is arranged along the first direction. Each heat exchanger 200 is provided with auxiliary flow channels on both sides along the first direction. One of the two outermost auxiliary flow channels is used to connect the outermost hot water outlet 240 with the first cooked water inlet, and the other is used to connect the outermost cold water outlet 220 with the first water inlet. The first water inlet is connected to the corresponding auxiliary flow channel through a connecting pipe. The first water outlet is also connected to the hot water inlet 230 through a connecting pipe. The two auxiliary flow channels on the sides of two adjacent heat exchangers 200 close to each other cooperate with at least one second waterway plate 520 to connect the cold water channels in the two adjacent heat exchangers 200 in series, and the hot water channels in the two adjacent heat exchangers 200 in series.

[0044] It should be noted that the first direction may be set as the width direction of the heat exchanger 200. When there are multiple second waterway plates 520, the shapes and internal structures of different second waterway plates 520 may be different.

[0045] As shown in FIG. 5 and FIG. 7 , in one embodiment, the heating and heat exchange device 10 further includes a one-inlet and two-outlet solenoid valve 420, the water inlet of the one-inlet and two-outlet solenoid valve 420 is connected to the hot water outlet 240, and the two water outlets of the one-inlet and two-outlet solenoid valve 420 are respectively connected to the first cooked water inlet and the water inlet end. In this way, the flow rate in the heat exchanger 200 can be set to be relatively large. When the user needs to take cooked water with a relatively low temperature, the heat exchanger 200 can provide sufficient low-temperature cooked water to reduce the user's waiting time; when the user needs to take cooked water with a relatively high temperature, the excess low-temperature cooked water can be returned to the water inlet end through the one-inlet and two-outlet solenoid valve 420 to be reheated and heat exchanged, thereby improving the practicality of the heating and heat exchange device 10.

[0046] As shown in Figures 5 and 7, in one embodiment, the heat exchange device 10 also includes a one-inlet and two-outlet solenoid valve 2 430, the water inlet of the one-inlet and two-outlet solenoid valve 2 430 is connected to the water outlet, and the two water outlets of the one-inlet and two-outlet solenoid valve 2 430 are respectively connected to the cold water inlet 210 and the first water inlet.

[0047] As shown in FIG. 5 and FIG. 7 , optionally, the heat exchanging device 10 further includes a third waterway plate 440. The self-priming pump 410 and the one-inlet and two-outlet solenoid valve 2 430 are both mounted on the third waterway plate 440. The third waterway plate 440 connects the water outlet with the water inlet of the one-inlet and two-outlet solenoid valve 2 430. In this way, the self-priming pump 410 and the one-inlet and two-outlet solenoid valve 2 430 are connected through the third waterway plate 440, which reduces the number of connecting pipes and is also conducive to the compact layout of the heat exchanging device 10, thereby improving the practicality of the heat exchanging device 10.

[0048] Specifically in this embodiment, the self-priming pump 410, the one-inlet and two-outlet solenoid valve 1 420 and the one-inlet and two-outlet solenoid valve 2 430 are all installed on the third waterway plate 440, and cooperate with the third waterway plate 440 to form a control waterway assembly.

[0049] As shown in FIG. 5 and FIG. 8 , in one embodiment, the heating and heat exchange device 10 further includes a flow meter 610, a zero pressure valve 620, and a fourth waterway plate 630 provided with a water inlet channel 631. The flow meter 610 and the zero pressure valve 620 are both installed on the fourth waterway plate 630. The flow meter 610 is used to detect the flow of the water inlet channel 631. The zero pressure valve 620 connects the water inlet channel 631 with the water inlet end. In this way, the self-priming pump 410 is connected to the pure water outlet of the water purifier through the zero pressure valve 620 and the fourth waterway plate 630, which reduces the number of connecting pipelines and is also conducive to the compact layout of the heating and heat exchange device 10, thereby improving the practicality of the heating and heat exchange device 10.

[0050] Specifically in this embodiment, the flow meter 610, the zero-pressure valve 620 and the fourth waterway plate 630 can cooperate to form a water inlet waterway assembly.

[0051] In one embodiment, a water purification device is provided, including a water purifier and the heating and heat exchanging device 10 in any of the above embodiments, the water purifier is connected to the heating and heat exchanging device 10, and is used to provide pure water to the heating and heat exchanging device 10. In this way, the water purification device includes the heating and heat exchanging device 10, so the water purification device has the technical effects of the heating and heat exchanging device 10, which will not be repeated here.
