Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, and in particular to an automatic circulating thermostat for bathtubs. Background Technology

[0002] In recent years, with the improvement of living standards, automatic circulating thermostats for bathtubs have gradually become an important part of bathroom equipment. They mainly use a water pump to drive water circulation and combine with a heating device to maintain a constant water temperature. The existing automatic circulating thermostats for bathtubs can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] Most commercially available automatic circulating thermostats for bathtubs employ a unidirectional jet design, resulting in low water circulation efficiency and temperature stratification in certain areas, leading to a poor user experience. Furthermore, the filter element, a key component in the circulating thermostat for filtering impurities in the water, needs to be replaced regularly. However, existing devices often use a fixed installation structure, making disassembly cumbersome and requiring tools, thus inconvenient to operate. Therefore, we propose an automatic circulating thermostat for bathtubs to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic circulating thermostat for bathtubs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic circulating thermostat for bathtubs, comprising a bathtub body, a headrest mounted on the top of the bathtub body, and a bottom cavity mounted on the bottom of the bathtub body. A thermostat water tank is disposed inside the bottom cavity. A first spray plate and a second spray plate are respectively installed on both sides of the inner wall of the bathtub body. Both the first and second spray plates are connected to the thermostat water tank via connecting pipes. A thermostat control box and a water pump are installed outside the thermostat water tank. A water inlet pipe is connected to the side of the thermostat water tank via a pipe. The water inlet pipe is installed on the inner wall of the bathtub body and communicates with the interior of the bathtub body. A filter element is disposed inside the water inlet pipe. An external thread is provided at the end of the water inlet pipe away from the thermostat water tank, and a filter cover is connected to the external thread of the external thread. An ejector assembly is disposed inside the water inlet pipe.

[0006] As an improved technical solution, the ejection assembly includes positioning side rods, positioning grooves, guide slide grooves, guide slide holes, push rods, and return springs. Positioning side rods are fixed on both sides of the outer wall of the filter element, and positioning grooves are opened on both sides of the inner wall of the water inlet pipe. The two sets of positioning side rods on the filter element can be inserted into the two sets of positioning grooves on the water inlet pipe. Guide slide grooves are opened at the ends of the two sets of positioning grooves facing the constant temperature water tank. Guide slide holes are provided in the two sets of guide slide grooves. Push rods are installed at the ends of the two sets of guide slide holes facing the positioning grooves. Return springs are provided inside the two sets of guide slide grooves.

[0007] As an improved technical solution, a signal box is installed on the outside of the bathtub body. The signal box contains a wireless communication module and forms a telecommunication connection with the thermostat control box.

[0008] As an improved technical solution, the first spray plate and the second spray plate are symmetrically placed inside the bathtub body, and multiple sets of nozzles are installed on both the first spray plate and the second spray plate.

[0009] As an improved technical solution, multiple sets of protruding plates are installed at equal intervals along the axis of the filter cover on the outer wall of the filter cover, and the outer side of each set of protruding plates is provided with anti-slip texture.

[0010] As an improved technical solution, the two ends of the return spring are respectively connected to the outer wall of the guide slide hole and the inner wall of the guide slide groove, and the guide slide hole is elastically connected to the inner wall of the guide slide groove through the return spring.

[0011] As an improved technical solution, the outer diameter of the guide sliding hole is the same as the inner diameter of the guide sliding groove, and the guide sliding hole and the guide sliding groove are slidably connected.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] I. This utility model features a first spray plate and a second spray plate installed on both sides of a constant-temperature water tank. These spray plates can spray water in opposite directions into the bathtub, thereby accelerating water circulation within the bathtub and preventing excessive temperature differences between different areas. This significantly improves heating uniformity and efficiency. Furthermore, a removable filter element is installed inside the water inlet pipe, and a filter cover is installed outside the water inlet pipe. The filter cover first filters the water entering the water inlet pipe to prevent larger impurities from entering. Then, the filter element inside the water inlet pipe further filters the water, ensuring the cleanliness of the water entering the constant-temperature water tank.

[0014] II. This utility model has two sets of movable guide sliders installed inside the water inlet pipe. After the filter cover is removed, the two sets of reset springs release their elasticity and push the two sets of guide sliders toward the positioning groove. The two sets of top rods on the two sets of guide sliders can apply force to the positioning rods on both sides of the filter element, so that the two sets of positioning rods drive the filter element to move outward from inside the water inlet pipe. This makes it easier to quickly remove the filter element from the water inlet pipe and improves the convenience of filter element replacement. Attached Figure Description

[0027] Figures 1 to 6 As shown, this embodiment provides an automatic circulating thermostat for a bathtub, including a bathtub body 1, a headrest 2 set at the top of the bathtub body 1, and a bottom cavity 3 set at the bottom of the bathtub body 1. A thermostat water tank 4 is set inside the bottom cavity 3. A first spray plate 5 and a second spray plate 6 are respectively installed on both sides of the inner wall of the bathtub body 1. The first spray plate 5 and the second spray plate 6 are both connected to the thermostat water tank 4 through connecting pipes 7. A thermostat control box 8 and a water pump 9 are installed outside the thermostat water tank 4. A water inlet pipe 10 is connected to the side of the thermostat water tank 4 through a pipe. The water inlet pipe 10 is installed on the inner wall of the bathtub body 1 and communicates with the inside of the bathtub body 1. A filter element 11 is set inside the water inlet pipe 10. An external thread 12 is set at the end of the water inlet pipe 10 away from the thermostat water tank 4. A filter cover 13 is connected to the external thread of the external thread 12. An ejector assembly is set inside the water inlet pipe 10.

[0028] By installing a first spray plate 5 and a second spray plate 6 on both sides of the constant temperature water tank 4, the first spray plate 5 and the second spray plate 6 can spray water in opposite directions into the bathtub body 1, thereby accelerating the water circulation inside the bathtub body 1 and preventing excessive temperature differences in different areas of the bathtub body 1, thus significantly improving heating uniformity and efficiency. Furthermore, by installing a removable filter element 11 inside the water inlet pipe 10 and installing a filter cover 13 outside the water inlet pipe 10, the filter cover 13 first filters the water entering the water inlet pipe 10 to prevent larger impurities from entering the water inlet pipe 10. Then, the filter element 11 inside the water inlet pipe 10 further filters the water passing through the water inlet pipe 10, thereby ensuring the cleanliness of the water entering the constant temperature water tank 4.

[0029] In other embodiments, the ejection assembly includes positioning side rods 15, positioning grooves 16, guide slides 17, guide sliders 18, push rods 19, and return springs 20. Positioning side rods 15 are fixed on both sides of the outer wall of the filter element 11, and positioning grooves 16 are opened on both sides of the inner wall of the water inlet pipe 10. The two sets of positioning side rods 15 on the filter element 11 can be inserted into the two sets of positioning grooves 16 on the water inlet pipe 10. Guide slides 17 are opened at the ends of the two sets of positioning grooves 16 that face the constant temperature water tank 4. Guide sliders 18 are provided in the two sets of guide slides 17. Push rods 19 are installed at the ends of the two sets of guide sliders 18 that face the positioning grooves 16. Return springs 20 are provided inside the two sets of guide slides 17.

[0030] By installing two sets of movable guide sliders 18 inside the water inlet pipe 10, after the filter cover 13 is removed, the two sets of reset springs 20 can release their elastic force to push the two sets of guide sliders 18 toward the positioning groove 16. This allows the two sets of push rods 19 on the two sets of guide sliders 18 to apply force to the positioning side rods 15 on both sides of the filter element 11, causing the two sets of positioning side rods 15 to move the filter element 11 from inside the water inlet pipe 10 outwards. This facilitates the quick removal of the filter element 11 from the water inlet pipe 10 and improves the convenience of replacing the filter element 11.

[0031] In other embodiments, a signal box 21 is installed on the outside of the bathtub body 1. The signal box 21 contains a wireless communication module and forms a telecommunication connection with the thermostat control box 8.

[0032] This design enables remote control of the signal box 21, allowing the thermostat control box 8 to adjust the water temperature and circulation mode, thus improving the user experience.

[0033] In other embodiments, the first spray plate 5 and the second spray plate 6 are symmetrically placed inside the bathtub body 1, and multiple sets of nozzles are installed on both the first spray plate 5 and the second spray plate 6.

[0034] This design allows multiple sets of nozzles on the first spray plate 5 and the second spray plate 6 to spray water in opposite directions, accelerating water circulation and heating the bathtub body 1 evenly.

[0035] In other embodiments, multiple sets of protruding plates 14 are installed at equal intervals along the axis of the filter cover 13 on the outer wall of the filter cover 13, and the outer side of each set of protruding plates 14 is provided with anti-slip texture.

[0036] With this design, when the filter cover 13 needs to be rotated, multiple sets of protrusions 14 can increase the friction between the hand and the surface of the filter cover 13, thereby facilitating the quick disassembly of the filter cover 13.

[0037] In other embodiments, the two ends of the return spring 20 are respectively connected to the outer wall of the guide slider 18 and the inner wall of the guide groove 17, and the guide slider 18 is elastically connected to the inner wall of the guide groove 17 through the return spring 20;

[0038] This design allows the return spring 20 to continuously apply a spring force toward the positioning groove 16 to the guide slider 18, so that the guide slider 18 can drive the push rod 19 to be quickly pushed out of the guide groove 17 under the action of the return spring 20.

[0039] In other embodiments, the outer diameter of the guide slider 18 is the same as the inner diameter of the guide groove 17, and the guide slider 18 and the guide groove 17 are slidably connected.

[0040] With this design, when the guide slider 18 moves laterally along the inside of the guide groove 17, it can effectively prevent the guide slider 18 from shaking during the movement, ensuring that the guide slider 18 can drive the push rod 19 to move smoothly.

[0041] This utility model provides an automatic circulating thermostat for bathtubs, the specific working principle of which is as follows:

[0042] When the thermostatic control box 8 detects that the water temperature is lower than the set value, it starts the water pump 9 to pump the heated water in the thermostatic water tank 4 into the first spray plate 5 and the second spray plate 6 through the connecting pipe 7. The symmetrically distributed nozzles form opposing water flows, which accelerates water circulation and heats the water evenly. The thermostatic water tank 4 draws water from the bathtub body 1 through the water inlet pipe 10 to achieve water circulation and heating. The user can remotely set the water temperature or switch the circulation mode through the signal box 21. The thermostatic control box 8 responds to the command in real time and adjusts the heating and water pump 9 operation status.

[0043] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
