Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, and in particular to a thermostat for a central air conditioning system for a water system. Background Technology

[0002] The water system central air conditioning thermostat is the core control device used to control the operation status of the water system central air conditioning and regulate the indoor temperature. It is generally installed and fixed on the wall surface.

[0003] Chinese Patent Publication No. CN218645735U discloses a wireless air conditioner thermostat, including a thermostat with a display screen on the front. Limiting posts are symmetrically arranged on the front of the thermostat and on the upper and lower sides of the display screen. The protective plate can be removed and replaced through the protective frame, avoiding the need for complete disassembly, making maintenance more convenient, time-saving and labor-saving. The overall device has a simple structure, is easy to operate and has higher practicality.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When using this device, manual adjustment is generally required through the buttons below the display screen. The protective plate only covers the display screen area, so it cannot protect the button area, which can easily cause accidental button presses. Furthermore, since there are gaps between the buttons and the thermostat, dust can easily accumulate in the gaps if there is no protection for a long time. Therefore, there is room for improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to protect the buttons on the thermostat from dust and accidental touch. To this end, we propose a water system central air conditioning thermostat.

[0006] To achieve the above objectives, this application adopts the following technical solution: a water system central air conditioning thermostat, comprising: a waste heat recovery tower, the bottom end of which is connected to the hot water inlet of an acetylene hydrochlorination reactor via a steam pipe; the hot water outlet of the acetylene hydrochlorination reactor is connected to the steam inlet in the middle of the waste heat recovery tower via a steam pipe; the steam pipe is configured as an upwardly inclined structure with a slope of not less than 5°; a gas-liquid separator is installed on the side of the steam pipe near the waste heat recovery tower; the bottom end of the gas-liquid separator is connected to the bottom end of the waste heat recovery tower via a water return pipe; the bottom end of the waste heat recovery tower is connected to the hot water inlet of a lithium bromide unit via hot water pipe A; and the hot water outlet of the lithium bromide unit is connected to the hot water return pipe via a water return pipe. The pipe is connected to the return main pipe, one end of which is connected to the hot water return port in the middle of the waste heat recovery tower. Circulation pump A is installed on hot water pipe A, hot water pipe B, and the return main pipe. Temperature sensors are installed on the pipes connected to the waste heat recovery tower, the acetylene hydrochlorination reactor, and the lithium bromide unit. The temperature sensor on hot water pipe B is located upstream of circulation pump A on hot water pipe B. Circulation pump A on the steam pipe is installed at a low position. Vibration damping supports are installed at equal intervals on hot water pipe A, hot water pipe B, hot water return pipe, and the return main pipe. Corrugated compensators are installed at equal intervals on hot water pipe A, hot water pipe B, hot water return pipe, and the return main pipe. Vibration damping supports and corrugated compensators are installed alternately.

[0007] Preferably, the steam pipe is equipped with a self-regulating pressure regulating valve, and the steam pipe is made of 80mm thick aluminum silicate fiber felt + aluminum sheet protective layer, and the outer surface temperature after insulation is ≤50℃.

[0008] Preferably, the top of the waste heat recovery tower is connected to an empty vent pipe, one end of which is equipped with a condenser. The bottom end of the condenser is connected to the liquid inlet in the middle of the waste heat recovery tower through a liquid replenishment pipe, and a circulation pump C is installed on the liquid replenishment pipe.

[0009] Preferably, one end of the lithium bromide generator is connected to a low-temperature water drain pipe, and one end of the low-temperature water drain pipe is connected to multiple branch pipes, one end of each branch pipe being connected to the low-temperature water inlet of the production equipment.

[0010] Preferably, the high-temperature water outlets of the production equipment are all connected to the return pipe through pipelines. One end of the return pipe is connected to the return port of the lithium bromide unit, and the other side of the return pipe is diverted to the interior of the main return pipe.

[0011] Preferably, a circulating pump B is installed on both the low-temperature water drain pipe and the return pipe, and an electromagnetic flow meter and an electric flow regulating valve are installed on the return pipe.

[0012] The technical effects and advantages of this utility model are as follows: In this utility model, the protective plate B is used to cover the front of the button, thereby preventing accidental button touch when the thermostat body is idle. It also provides a certain dust protection effect. In addition, the protective plate B can be flipped and adjusted by the groove through the cooperation of the connecting plate and the connecting shaft, so as not to affect the normal use of the button. Furthermore, by utilizing the magnetic attraction of the lower and upper magnetic blocks, the protective plate B can be automatically fixed when flipped to the front by simply moving the groove, thereby improving the convenience of daily use of the protective plate B.

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] Reference Figures 1-3As shown, this utility model provides a technical solution: a water system central air conditioning thermostat, including: a thermostat body 1, a display screen 7 and a button 8 on the front of the thermostat body 1, the button 8 being located below the display screen 7, a protective component A2 on the front of the thermostat body 1 covering the front of the display screen 7, a protective component B4 at the bottom of the protective component A2, the protective component B4 including connecting plates 43 fixed to the bottom of both sides of the protective component A2, connecting shafts 44 fixed to the bottom of the connecting plates 43 near the inner side of the thermostat body 1, the two connecting shafts 44 being connected to the protective plate B41, a groove 42 on the front of the protective plate B41, a lower magnetic block 5 fixed to the top of the protective plate B41, and an upper magnetic block 6 fixed to the bottom of the protective component A2. When the lower magnetic block 5 and the upper magnetic block 6 are magnetically fixed, the protective plate B41 is located in front of the button 8.

[0018] The protective plate B41 is used to cover the button 8 for daily use. The connecting shaft 44 enables the protective plate B41 to rotate without affecting the normal use of the button 8. The magnetic fixing effect between the lower magnetic block 5 and the upper magnetic block 6 can be used to quickly fix the protective plate B41. That is, during operation, the position of the protective plate B41 can be quickly adjusted by moving the groove 42. The protective plate B41 effectively prevents the button 8 from being accidentally pressed and improves the dust protection effect.

[0019] Reference Figure 2 , Figure 3 As shown in this embodiment: the protective component A2 includes a protective plate A22, and the inner walls of the two opposite sides of the protective plate A22 are fixed with slide bars 23. The thermostat body 1 has slide grooves 21 on both opposite sides. The slide grooves 21 are far away from the display screen 7, and the slide bars 23 slide along the slide grooves 21.

[0020] The sliding groove 21 and the sliding strip 23 are used together to achieve the up-and-down sliding installation of the protective plate A22, which is convenient to operate.

[0021] Both protective plate A22 and protective plate B41 have a U-shaped cross-section when viewed from above. There is a gap between the inner wall of protective plate A22 and the front of the thermostat body 1. Protective plate B41 is rotatably connected by connecting holes on both sides and connecting shaft 44.

[0022] The U-shaped structure expands the protection range, and the U-shaped corners of the protective plates A22 and B41 are rounded, which provides anti-collision protection. The gap between the protective plate A22 and the thermostat body 1 is used to reduce the direct impact of the protective plate A22 on the display screen when it is hit, thus providing a certain buffer space.

[0023] The top view of the slide 21 and the protective plate A22 are both right trapezoidal. The length of the slide 21 is less than the width of the thermostat body 1. The protective plate A22 is transparent. The slide 21 and the adjacent protective plate A22 are both connected to a fixing component 3.

[0024] The sliding groove 21 restricts the movement distance of the protective plate A22 and limits its mobility, thereby achieving the effect of impact protection. After the protective plate A22 has finished sliding, it can be supported.

[0025] Reference Figure 4 , Figure 5 As shown in this embodiment: the fixing component 3 includes a fixing groove 31 opened on the inclined surface of the slide 21, and a through hole 32 is opened on the side of the protective plate A22 near the fixing groove 31. A fixing member 33 is provided inside the through hole 32, and one end of the fixing member 33 extends synchronously into the interior of the slide 21 and the fixing groove 31.

[0026] By using the fastener 33 to connect the fixing groove 31 and the sliding groove 21, the upward sliding of the protective plate A22 is hindered, thereby achieving the effect of fixing the position of the protective plate A22.

[0027] The fastener 33 includes an irregularly shaped spring sheet 331, which has a W-shaped cross-section when viewed from above. One end of the irregularly shaped spring sheet 331 is fixed with a fixed plate 332, and the other end of the irregularly shaped spring sheet 331 is fixed with a movable plate 333. The fixed plate 332 is fixedly connected to one side of the through hole 32, and the movable plate 333 is slidably connected to one side of the through hole 32. The movable plate 333 is located on the side of the through hole 32 near the fixed groove 31.

[0028] By utilizing the elastic characteristics of the irregularly shaped spring sheet 331, the irregularly shaped spring sheet 331 can be compressed by pushing the movable plate 333, so that the irregularly shaped spring sheet 331 only occupies the space of the slide groove 21, thereby realizing the vertical sliding of the protective plate A22.

[0029] Working principle: The user first pushes the movable plates 333 on both sides outward to further compress the irregular spring sheet 331, then stands the protective plate A22 upright, slides the slider 23 along the slide groove 21 to the bottom, and then releases the movable plates 333 to reset the irregular spring sheet 331, so that one end of the irregular spring sheet 331 is simultaneously inserted into the slide groove 21 and the fixing groove 31, thereby realizing the synchronous installation and fixing of the protective plate A22 and the protective component B4; when the button 8 needs to be used, by pushing the groove 42 downward, the protective plate B41 is flipped downward along the connecting shaft 44, separating the lower magnetic block 5 and the upper magnetic block 6, thereby exposing the button 8. Then, pushing the groove 42 upward, the protective plate B41 is flipped, and as the lower magnetic block 5 and the upper magnetic block 6 gradually approach each other, the lower magnetic block 5 and the upper magnetic block 6 are magnetically attracted and fixed to each other, thereby keeping the protective plate B41 in a state of blocking the button 8.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
