Description

Technical Field

[0001] This utility model relates to the field of booster water return device technology, and in particular to a circulating booster water return device. Background Technology

[0002] A circulating booster water return device is a device used in hot water circulation systems. Its core working principle is to send cold water in the hot water pipes back to the heating tank for heating through forced circulation and temperature control, so as to achieve the effect of "instant hot water".

[0003] In the working process of the circulating booster water return device, a temperature sensor is installed at the end of the hot water pipe to monitor the water temperature in the hot water pipe in real time. When the water temperature is lower than the preset value on the thermostat, the PLC preset in the thermostat will control the start of the booster pump. After the booster pump starts, the cold water that is stuck in the hot water pipe is pumped back to the heating tank through the return water pipe. The heating tank reheats the returned cold water to the preset temperature of hot water (existing technology) through pipeline gas. Then, it is transported back to the inner cavity of the end pipe through the hot water pipe to form a closed loop. When the water temperature in the inner cavity of the end of the hot water pipe reaches the set preset value, the booster pump stops running and waits for the next trigger.

[0004] Currently, existing circulating booster water return systems typically have a control panel pre-installed on the heating tank. This control panel includes a display screen and buttons. Users can input the desired preset heating temperature value through the buttons, and the display screen shows the preset temperature value. However, during daily use, people's skin or sharp objects may directly bump into or touch the display screen and buttons, causing scratches on the display screen and accidental button inputs. This significantly reduces the daily protection of the display screen and buttons on the control panel of the circulating booster water return system.

[0005] Therefore, we designed a circulating booster water return device to meet the needs of practical applications. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a circulating booster water return device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Design a circulating booster water return device, including a heating box, a wall at the back of the heating box, a screw groove on the heating box, a guide rail and a control panel on the heating box, a display screen and buttons on the control panel, a water-using device on the right side of the heating box, a cold water pipe and a hot water pipe connected to the water-using device, a return water pipe connected to the hot water pipe, a cold water supply pipe connected to the cold water pipe, a sliding plate slidably connected inside the guide rail, a sliding cover on the sliding plate, a fixed plate and a rib plate on the sliding cover, and a screw pin threaded on the fixed plate; The screw is provided with a pin shank disc and a spring post, and the pin shank disc is provided with a finger groove and a spring washer is provided in the finger groove. The guide rail is provided with a stop block, the stop block is provided with a slot, and the rib plate is provided with a post.

[0008] In detail, the return water pipe is connected to the heating box, the cold water pipe and the hot water pipe are respectively connected to the heating box, the cold water supply pipe is equipped with a valve, and the return water pipe is equipped with a one-way valve.

[0009] In detail, the guide rail has an L-shaped cross-section when viewed from above and is slidably engaged with the slide plate. The slide cover is provided with ball bearings, and two-thirds of the ball bearings are rotatably engaged in the slide cover and roll in contact with the outer wall of the heating box.

[0010] In detail, the sliding cover has a U-shaped cross-section when viewed from above, and the entire sliding cover is made of transparent PVC.

[0011] In detail, the stop block is disposed on the lower end surface of the guide rail, and the spring column has an overall cylindrical structure.

[0012] In detail, the ribs are in two symmetrical sets, with two symmetrical ribs in each set. The ribs are triangular in shape and are located between the slide plate and the cover.

[0013] In detail, the finger groove is an arc-shaped groove structure with six arranged in a circle, and the spring pads are evenly distributed along the groove surface of the finger groove.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model symmetrically arranges guide rails with blocks on the outer wall of the heating box, and sets up a sliding cover with a sliding plate. The sliding cover is equipped with a threaded snap-fit ​​positioning structure. After the temperature value is preset by the buttons on the control panel, the sliding cover can be slid upward to position and cover the display screen and buttons on the control panel. This prevents people's skin or sharp objects from directly colliding or touching the display screen and buttons during daily use, thus effectively preventing scratches on the display screen and accidental button input. Overall, it improves the daily protection of the display screen and buttons on the control panel of the circulating booster water return device.

[0015] 2. This utility model provides four ball bearings on the sliding cover. When the sliding cover moves up and down, the ball bearings roll along the outer wall of the heating box, thus avoiding scratches on the outer wall of the heating box.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5A circulating booster water return device includes a heating box 1, a wall 11 at the back end of the heating box 1, a screw groove 12 on the heating box 1, a guide rail 13 and a control panel 6 on the heating box 1, a display screen 61 and buttons 62 on the control panel 6, a water-using device 2 on the right side of the heating box 1, a cold water pipe 21 and a hot water pipe 22 connected to the water-using device 2, a return water pipe 4 connected to the hot water pipe 22, a cold water supply pipe 3 connected to the cold water pipe 21, a sliding plate 53 slidably connected inside the guide rail 13, a sliding cover 5 on the sliding plate 53, a fixed plate 8 and a rib plate 51 on the sliding cover 5, and a screw pin 811 threaded on the fixed plate 8; The screw pin 811 is provided with a pin handle plate 9 and a spring post 82. The pin handle plate 9 is provided with a finger groove 91 and a spring washer 92 is provided in the finger groove 91. A stop 7 is provided on the guide rail 13, and a slot 71 is provided on the stop 7. A post 52 is provided on the rib plate 51. The heating box 1 is a commonly used circulating booster water return device, which is equipped with a waterproof booster pump and a waterproof thermostat. Meanwhile, the water-using equipment 2, the one-way valve 41, the control panel 6, the display screen 61, and the button 62 are all existing technologies. A temperature sensor is pre-installed between the end of the hot water pipe 22 and the water-using equipment 2. This is also existing technology. The related functions of the undrawn structures are also existing technologies and need not be described in detail.

[0021] The heating box 1 is installed and fixed to the wall 11 by expansion bolts, which is the existing technology.

[0022] The screw groove 12 is not through to prevent water leakage.

[0023] It should be further explained that the return water pipe 4 is connected to the heating box 1, the cold water pipe 21 and the hot water pipe 22 are respectively connected to the heating box 1, and the cold water supply pipe 3 is equipped with a valve 31. The left end of the cold water supply pipe 3 is connected to the main tap water pipe. By opening the manual valve 31, cold tap water can be delivered to the cold water pipe 21 and the heating box 1, which is the existing technology.

[0024] The return water pipe 4 is equipped with a one-way valve 41, which can only be drawn into the heating box 1 by the booster pump in one direction.

[0025] It should be further noted that the top view of the guide rail 13 is an L-shaped structure and it is matched and slidably engaged with the slide plate 53, thereby realizing the guiding vertical sliding effect of the slide cover 5.

[0026] The sliding cover 5 is equipped with a ball bearing 50. Two-thirds of the ball bearing 50 is rotated and engaged in the sliding cover 5 and rolls in contact with the outer wall of the heating box 1. The ball bearing 50 is made of aluminum alloy, which is durable and lightweight, and at the same time prevents it from slipping out of the sliding cover 5.

[0027] It should be further noted that the sliding cover 5 has a U-shaped cross-section when viewed from above. The sliding cover 5 is made of transparent PVC, which is impact-resistant and durable. It completely covers the control panel 6, while the display content of the display screen 61 can be viewed in real time through the sliding cover 5.

[0028] It should be further explained that the stop 7 is set on the lower end face of the guide rail 13. The spring post 82 has an overall cylindrical structure and is made of high elastic silicone material. When the screw pin 81 is threaded into the screw groove 12, the spring post 82 will be squeezed and generate a rebound force. This rebound force acts on the screw pin 81, realizing the anti-loosening effect of the screw pin 81.

[0029] When the sliding cover 5 is slid down, and the insert 52 is inserted into the slot 71, the control panel 6 is fully exposed, making it convenient to use the control panel 6.

[0030] It should be further explained that the ribs 51 are two sets that are symmetrical from left to right, with two symmetrical ribs in each set. The ribs 51 are triangular in shape and are located between the slide plate 53 and the cover 5. The ribs 51 are made of aluminum alloy, which is lightweight, strong, durable, and has high stability due to their triangular shape.

[0031] It should be further noted that the finger groove 91 is an arc-shaped groove structure with six arranged in a circle, which makes it easy to insert fingers and directly rotate the screw pin 81, which is very convenient.

[0032] The spring pads 92 are evenly arranged along the groove surface of the finger groove 91. The spring pads 92 are made of polyurethane rubber pad material, which has high elasticity and wear resistance, and improves the comfort when the fingers press the finger groove 91.

[0033] Operating method: In actual use, a temperature sensor is installed at the end of the hot water pipe 22 to monitor the water temperature in the hot water pipe 22 in real time (not shown, existing technology). When the water temperature is lower than the preset value on the thermostat (preset in the heating box 1, existing technology), the PLC preset in the thermostat will control the start of the booster pump (preset in the heating box 1, existing technology). After the booster pump starts, the cold water that is stuck in the hot water pipe 22 is pumped back to the heating box 1 through the return water pipe 4. The heating box 1 reheats the returned cold water to the preset temperature of hot water through pipeline gas (existing technology), and then delivers it to the inner cavity of the end pipe of the hot water pipe 22 again to form a closed loop for use by the backup water device 2 for hot and cold water. When the water temperature in the inner cavity of the end of the hot water pipe 22 reaches the set preset value, the booster pump stops running and waits for the next trigger.

[0034] See Figure 1When the temperature value is preset via button 62 on control panel 6, the preset temperature value will be displayed on display panel 61. Then, move the sliding cover 5 upward, causing the slide plate 53 to slide steadily upward along guide rail 13. When the screw pin 811 is aligned with the screw groove 12, the sliding cover 5 has completely covered and protected the display screen 61 and button 62 on control panel 6. Next, insert your finger into the finger groove 91 and rotate it clockwise, causing the pin handle plate 9 and screw pin 811 to rotate clockwise. Through the threaded transmission with the fixed plate 8, the screw pin 811 is threadedly locked with the screw groove 12, thus locking the sliding cover 5 in place. This prevents people's skin or sharp objects from directly colliding or touching the display screen 61 and button 62 during daily use, effectively preventing scratches on the display screen 61 and mis-input of the button 62. Overall, this improves the daily protection of the display screen 61 and button 62 on control panel 6 of the circulating booster water return device.

[0035] Furthermore, when the sliding cover 5 slides up and down, the ball bearing 50 rolls along the outer wall of the heating box 1, thus avoiding scratches on the outer wall of the heating box 1.

[0036] In addition, by setting a triangular rib plate 51 structure between the slide plate 53 and the slide cover 5, the structural stability between the slide plate 53 and the slide cover 5 is further improved, thereby ensuring the guiding stability of the slide plate 53 sliding in the guide rail 13.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
