Description

Technical Field

[0001] This utility model belongs to the field of fluid regulation equipment technology, and more specifically, it relates to a water circulation structure with a heating and cooling mode. Background Technology

[0002] In the field of HVAC and heating systems for both commercial and residential buildings, water circulation structures with both heating and cooling modes are used to ensure stable and controllable indoor and outdoor temperatures and production environments, thereby supporting the core needs of comfortable living. Existing water circulation structures with both heating and cooling modes generally consist of cold water inlet and outlet, hot water inlet and outlet, mixing valve, and booster pump.

[0003] Based on the above, during the daily operation and maintenance of the water circulation structure, if there is accidental contact by personnel, slight vibration of the equipment, or accidental scraping by surrounding objects, the adjustment handle of the mixing valve is prone to unexpected rotation, which directly changes the opening of the mixing valve or related control valves, thereby breaking the preset mixing ratio of hot and cold water, and ultimately causing the output water temperature to fluctuate suddenly, affecting production and daily life. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a water circulation structure with both hot and cold modes. This solves the problem that during the daily operation and maintenance of existing water circulation structures, if there are situations such as accidental contact by personnel, slight vibration of the equipment, or accidental scraping by surrounding objects, the adjustment handle of the mixing valve is prone to unexpected rotation, which directly changes the opening of the mixing valve or related control valves, thereby breaking the preset mixing ratio of hot and cold water, and ultimately causing sudden fluctuations in the output water temperature, affecting production and daily life.

[0005] The purpose and function of this utility model's water circulation structure with both heating and cooling modes are achieved through the following specific technical means: A water circulation structure with both hot and cold modes includes a water pump, a mixing valve, a hot water inlet, a hot water outlet, a first connecting pipe, a three-way valve, an adjusting handle, a mixing assembly, and an event indicator assembly. The mixing valve is fixedly connected to the left side of the water pump; the hot water inlet is fixedly connected to the left side of the mixing valve; the hot water outlet is fixedly connected to the rear of the hot water inlet; the first connecting pipe is an "L"-shaped mechanism, with its front end fixedly connected to the rear of the mixing valve; the three-way valve is fixedly connected to the right end of the first connecting pipe; the adjusting handle is rotatably connected inside the mixing valve; the mixing assembly is located to the right of the three-way valve and in front of the mixing valve; and the event indicator assembly is located in front of the mixing valve.

[0006] Furthermore, the mixing assembly includes: a cold water inlet, a second connecting pipe, and a mixed water outlet; the left end of the cold water inlet is fixedly connected to the right side of the three-way valve; the rear end of the second connecting pipe is fixedly connected to the front end of the three-way valve; the left end of the mixed water outlet is fixedly connected to the right side of the water pump, and the mixed water outlet is connected to the front end of the second connecting pipe.

[0007] Furthermore, the mixing assembly also includes: a sliding groove, a sliding guide block, and an operating plate; the sliding groove is located at the bottom of the adjusting handle; the sliding guide block is slidably connected inside the sliding groove; and the bottom of the operating plate is fixedly connected to the rear of the sliding guide block.

[0008] Furthermore, the mixing assembly also includes: a limiting post and a reset spring; the limiting post is fixedly connected to the rear top of the operating panel; two reset springs are provided, the front ends of the two reset springs are respectively fixedly connected to the inside of the adjusting handle, and the rear ends of the two reset springs are respectively fixedly connected to the front of the operating panel.

[0009] Furthermore, the mixing assembly also includes: a positioning plate and positioning holes; the positioning plate is fixedly connected to the outside of the mixing valve; multiple positioning holes are provided, and the multiple positioning holes are respectively provided inside the bottom of the positioning plate, with a limiting post inserted into one of the positioning holes.

[0010] Furthermore, the event indication component includes: an indicator needle and a label plate; the indicator needle is fixedly connected to the top of the adjustment handle; multiple labels plate are provided, and the multiple labels plate are respectively fixedly connected to the front of the top of the positioning plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: First, by clearly defining the functional division of hot and cold water inlets and outlets and the mixed water outlet, and coordinating the control of the mixing valve and the three-way valve, the switching process of the three modes of "pure hot water, pure cold water, and mixed water" is simplified. It can quickly adapt to different water demand without complicated debugging. By equipping a mechanical anti-accidental touch structure, it fundamentally avoids the unexpected rotation of the adjustment handle due to accidental touch, vibration, or scratch, ensuring the stability of valve opening and hot and cold water mixing ratio, completely solving the problem of sudden water temperature changes, and ensuring the comfort of domestic water use.

[0012] Secondly, by marking the specific usage scenarios corresponding to different water temperatures on the label, the indicator needle will synchronously move and point to the label corresponding to the scenario when the adjustment handle is turned. This achieves an intuitive correspondence between scenario requirements and water temperature adjustment, greatly reducing the trial-and-error costs of operators repeatedly testing water temperatures. At the same time, this design eliminates the need for operators to memorize the correspondence between handle angle and water temperature, significantly lowering the operating threshold for novice or non-professional maintenance personnel.

[0013] This utility model simplifies the switching process between three modes: "pure hot water, pure cold water, and mixed water". It is also equipped with a mechanical anti-accidental touch structure to prevent the adjustment handle from rotating unexpectedly due to accidental contact, thus solving the problem of sudden water temperature changes. Furthermore, it uses a poster board to mark the scene and link it with the indicator needle to achieve an intuitive correspondence between scene requirements and water temperature adjustment, which can more accurately and efficiently adapt to the diverse water temperature requirements of HVAC systems in commercial buildings.

[0024] The mixing assembly also includes: a limiting post 1201 and a reset spring 1202; the limiting post 1201 is fixedly connected to the rear of the top of the operating plate 12; two reset springs 1202 are provided, the front ends of the two reset springs 1202 are fixedly connected to the inside of the adjusting handle 10, and the rear ends of the two reset springs 1202 are fixedly connected to the front of the operating plate 12.

[0025] The mixing assembly also includes: a positioning plate 13 and a positioning hole 1301; the positioning plate 13 is fixedly connected to the outside of the mixing valve 2; multiple positioning holes 1301 are provided, and multiple positioning holes 1301 are respectively provided inside the bottom of the positioning plate 13, and the limiting post 1201 is inserted into the inside of one positioning hole 1301.

[0026] The specific usage and function of this embodiment are as follows: During use, the hot water inlet 3 is connected to an external hot water pipe, and the cold water inlet 7 is connected to an external cold water pipe. When hot water is needed, it enters through the hot water inlet 3, and the three-way valve 6 is closed, allowing the hot water to flow directly out from the hot water outlet 4 when the switch is open. When cold water is needed, it enters through the cold water inlet 7. The cold water entering the first connecting pipe 5 from the cold water inlet 7 is blocked by the closed three-way valve 6, and the cold water flows out from the mixed water outlet 9 when the switch is open. When mixing hot and cold water is needed, the three-way valve 6 is opened, and the hot water outlet 4 is closed. At this time, cold water enters through the cold water inlet 7, flows through the three-way valve 6 and the first connecting pipe 5, mixes with the hot water entering from the hot water inlet 3, and after being pressurized by the water pump 1, the mixed water flows out from the mixed water outlet when the switch is open. Nine outlets are discharged. When adjusting the opening of the mixing valve 2 by adjusting the handle 10 to adjust the temperature of the mixed water, first, you need to hold the handle 10 with your hand, and then use your fingers to press the operating plate 12. Under the guidance of the sliding groove 1001 and the sliding guide block 11, the operating plate 12 moves forward, so that the limiting post 1201 disengages from the currently inserted positioning hole 1301. After this operation, you can adjust the position of the handle 10 left and right to avoid the temperature fluctuation of the mixed water caused by accidental contact of the handle 10. After adjusting the handle 10 to the appropriate position, release the operating plate 12. Under the rebound action of the two return springs 1202, the limiting post 1201 inserts into the corresponding positioning hole 1301, and the position of the handle 10 is automatically fixed.

[0027] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes an event indicator component, which is located in front of the mixing valve 2.

[0029] The specific usage and function of this embodiment: The surface of multiple labeling plates 1302 can be labeled with the items or functions to be achieved corresponding to the water temperature. When the adjustment handle 10 is adjusted left and right, the position of the indicator needle 1002 changes accordingly, and the labeling plate 1302 indicated by the indicator needle 1002 changes accordingly, so as to facilitate the adjustment of the position of the adjustment handle 10 according to the work to be performed.
