Description

Technical Field

[0001] The present application relates to the field of water treatment, and particularly to a water temperature regulating device, a hot water device, and a heating system. Background Art

[0002] In the prior art, some water heating mechanisms can be provided with a water temperature regulating device to make the temperature of the water output therefrom meet the preset requirements.

[0003] The water temperature regulating device includes a cold water path, a hot water path, and a mixing path. Among them, the cold water path and the hot water path are respectively communicated with the mixing path, so that cold water and hot water can be respectively guided into the mixing path. At present, some water temperature regulating devices can adjust the opening degree of the cold water path or the hot water path, so as to adjust the water temperature of the mixing path. However, since such a water temperature regulating device only adjusts the opening degree of one of them, the adjustment range of the water temperature regulating device will be limited. For example, the flow rate of the hot water path of the water temperature regulating device is 1.5 L / min, the adjustable range of the flow rate of the cold water path is between 0 and 1.75 L / min, and the preset temperature of the water temperature regulating device is 45 °C. If the temperature in the hot water path is 80 °C and the temperature in the cold water path is 18 °C, even when the flow rate of the cold water path is adjusted to the maximum value (i.e., 1.75 L / min), the temperature of the outlet water cannot meet the preset requirements. At present, some other water temperature regulating devices can simultaneously adjust the flow rates of the hot water path and the cold water path. In this case, it is necessary to provide an element in the hot water path that can adjust the opening degree of the hot water path. However, since the water temperature in the hot water path is relatively high, scale is likely to be generated in the element in the hot water path, resulting in inaccurate outlet water temperature of the water temperature regulating device, and even the failure of temperature adjustment due to the blockage of the hot water regulating opening caused by the accumulation of scale.

Detailed implementation manners

[0053] Combined with the description of the specific implementation manners of the present application and the drawings, the details of the present application can be more clearly understood. However, the specific implementation manners of the present application described herein are only for the purpose of explaining the present application and cannot be understood in any way as a limitation to the present application. Under the teaching of the present application, those skilled in the art can conceive any possible deformation based on the present application, and these should be regarded as belonging to the scope of the present application.

[0054] Referring to Figure 1 As shown, an embodiment of the present application discloses a water temperature adjusting device 36, including a valve body 17, including a hot water path 10, a cold water inlet path 11, and a mixing water path 12; the mixing water path 12 can be communicated with the hot water path 10; a temperature sensing and adjusting mechanism, including a temperature sensing element 13 and an adjusting part 14, the temperature sensing element 13 senses the temperature change and deforms itself to drive the adjusting part 14 to move, dividing the water outlet end of the cold water inlet path 11 into a first cold water path 15 that can be communicated with the mixing water path 12 and a second cold water path 16 that can be communicated with the outside of the valve body 17.

[0055] With the above structure, the temperature change is sensed by the temperature sensing element 13 to divide the water outlet end of the cold water inlet path 11, forming a first cold water path 15 and a second cold water path 16. Since the flow rate in the second cold water path 16 corresponds to the flow rate in the hot water path 10 (for example, the flow rate in the second cold water path 16 and the flow rate in the hot water path 10 can be in a positive correlation or an equal relationship), the flow rates in the first cold water path 15 and the second cold water path 16 are adjusted, that is, the flow rates and proportions of the cold water and hot water entering the mixing path 12 are adjusted simultaneously. Therefore, the adjusting part 14 can adjust the water temperature in the mixing path 12 by forming the first cold water path 15 and the second cold water path 16. Since the hot water and cold water entering the mixing path 12 are adjusted simultaneously, the temperature adjustment range of the water temperature adjusting device 36 is relatively wide.

[0056] Moreover, the adjusting part 14 is arranged in the cold water inlet path 11, so there is no problem of scale formation in the adjusting part 14. In addition, the water temperature adjusting device 36 adopts a mechanical structure, that is, a temperature sensing element 13 based on its own deformation is arranged to control the position of the adjusting part 14. Correspondingly, the water temperature adjusting device 36 does not need to be additionally provided with other sensing elements or electric control mechanisms, so the structure and control principle of the water temperature adjusting device 36 are simple.

[0057] Specifically, the valve body 17 is provided with a hot water inlet 20, a mixing water outlet 21, a cold water inlet 22, and a cold water outlet 23; the water inlet end of the cold water inlet path 11 is communicated with the cold water inlet 22; the water outlet end of the second cold water path 16 is communicated with the cold water outlet 23; the water inlet end of the hot water path 10 is communicated with the hot water inlet 20; the water outlet end of the mixing path 12 is communicated with the mixing water outlet 21.

[0058] In order to enable the temperature sensing element 13 to drive the adjusting part 14 to move, the adjusting part 14 is formed by the temperature sensing element 13 or a part thereof; or is connected to the temperature sensing element 13.

[0059] In an alternative embodiment, the temperature sensing element 13 is disposed in the mixing water path 12. When the water temperature in the mixing water path 12 exceeds the preset temperature, the temperature sensing element 13 may undergo a corresponding deformation (e.g., shortening), thereby expanding the first cold water path 15 and reducing the second cold water path 16, increasing the amount of cold water entering the mixing water path 12 and reducing the amount of hot water entering the mixing water path 12, so as to adjust the water temperature in the mixing water path 12 to the preset temperature. On the contrary, when the water temperature in the mixing water path 12 is lower than the preset temperature, the temperature sensing element 13 may undergo a corresponding deformation (e.g., elongation), reducing the first cold water path 15 and expanding the second cold water path 16. In another alternative embodiment, the temperature sensing element 13 may also be disposed in the hot water path 10. Correspondingly, the temperature sensing element 13 also deforms based on the water temperature in the hot water path 10 to adjust the water temperature in the mixing water path 12.

[0060] Specifically, the present application discloses a water temperature regulating device 36, the valve body 17 of which includes a first pipe body 30 and a second pipe body 31 disposed outside the first pipe body 30. A mixing water path 12 is provided in the first pipe body 30. The lower end of the first pipe body 30 has a mixing water outlet 21 communicating with the mixing water path 12. The second pipe body 31 extends out of the upper end of the first pipe body 30, and the part of the second pipe body 31 extending out of the first pipe body 30 forms a hot water inlet 20 and at least part of the hot water path 10. A cold water inlet path 11 is formed between the first pipe body 30 and the second pipe body 31. A temperature sensing element 13 is disposed in the first pipe body 30, and the adjusting portion 14 is cooperatively installed with the first pipe body 30 and can move in the up and down direction.

[0061] In this embodiment, referring to Figure 1 as shown, a cold water inlet 32 is formed on the side wall of the first pipe body 30. The adjusting portion 14 can adjust the opening degree of the cold water inlet 32 during the up and down movement. The adjusting portion 14 and the inner side wall of the second pipe body 31 form a cold water outlet 23. The adjusting portion 14 can adjust the opening degree of the cold water outlet 23 during the up and down movement. It should be noted that the opening degrees of the cold water inlet 32 and the cold water outlet 23 should change in the opposite direction. That is, when the opening degree of the cold water inlet 32 becomes larger, the opening degree of the cold water outlet 23 should become smaller. Or, when the opening degree of the cold water inlet 32 becomes smaller, the opening degree of the cold water outlet 23 should become larger. Thus, it is ensured that the sum of the flow rates of the first cold water path 15 and the second cold water path 16 is equal to the flow rate of the cold water inlet path 11.

[0062] Among them, the second pipe body 31 has an extension part extending downward. The upper end of the adjusting part 14 is sleeved on the extension part. The lower end of the adjusting part 14 is connected to the upper end of the temperature sensing element 13 (such as a thermal spring). The lower end of the temperature sensing element 13 is connected to the first pipe body 30. A return spring 37 is arranged between the upper end of the adjusting part 14 and the second pipe body 31.

[0063] Referring to Figure 2 and 3 As shown, a cold water inlet 32 is formed between the upper end of the first pipe body 30 and the adjusting part 14. The cold water outlet 23 is arranged on the side wall of the second pipe body 31. The adjusting part 14 is cooperatively installed with the cold water outlet 23 to adjust the opening degree of the cold water outlet 23.

[0064] Referring to Figure 4 and 5 As shown, a cold water inlet 32 is formed between the upper end of the first pipe body 30 and the adjusting part 14. The cold water outlet 23 is formed between the inner side wall of the second pipe body 31 and the adjusting part 14.

[0065] In another alternative embodiment, the cold water outlet 23 is formed between the first pipe body 30 and the adjusting part 14. The second cold water path 16 further includes an opening provided on the side wall of the second pipe body 31 and a channel provided on the first pipe body 30 and used for communicating the cold water outlet 23 and the opening.

[0066] Referring to Figure 1 As shown, in another preferred embodiment, one end of the adjusting part 14 is cooperatively installed with the first pipe body 30; the other end of the adjusting part 14 extends out of the first pipe body 30. The adjusting part 14 includes a sealing part 34 that is hermetically sealed with the inner wall of the second pipe. The sealing part 34 is used to isolate the hot water path 10 and the second cold water path 16.

[0067] Of course, in other alternative embodiments, the temperature sensing element 13 may further include other devices such as a thermosensitive metal or a paraffin package that can change shape based on temperature.

[0068] Referring to Figure 6As shown, the embodiment of the present application also discloses a hot water device, including the water temperature adjustment device 36 as described above. The hot water outlet part of the heating device is connected to the hot water inlet 20 of the water temperature adjustment device 36, and the cold water inlet part 43 of the heating device is connected to the cold water outlet 23 of the water temperature adjustment device 36.

Preferably, the temperature sensing element 13 can be arranged in the mixing path 12 of the water temperature adjustment mechanism, or in the outlet part of the heating device, or in the hot water path 10 of the water temperature adjustment mechanism.

[0069] In this embodiment, the heating device is a storage water heater including an inner tank 35. The lower ends of the first pipe body 30 and the second pipe body 31 are both located in the inner tank 35. The first pipe body 30 and the second pipe body 31 extend upward and extend into the inner tank 35. The hot water inlet 20 of the water temperature adjustment device 36 is communicated with the upper part of the inner tank 35, so that hot water can be obtained from the inner tank 35. The cold water outlet 23 of the water temperature adjustment device 36 is communicated with the lower part of the inner tank 35, so that cold water can be input into the inner tank 35.

[0070] In a preferred embodiment, the water temperature adjustment device further includes a knob (not shown in the figure) capable of driving the first pipe body 30 to move relative to the second pipe body 31, so as to adjust the deformation amount of the induction deformation element, so as to adaptively adjust the preset temperature of each hot water device. For example, an external thread is provided on the second pipe body 31, and a matching internal thread is provided on the inner tank 35.
