Description

Technical Field

[0001] This utility model belongs to the field of thermostat technology, specifically a thermostat equipped with F-type inlet and outlet water pipes. Background Technology

[0002] Currently, bottom-fill thermostats on the market come in two types of outlet pipes: center outlet and side outlet. When used with a kettle, changing the outlet method requires disassembling the thermostat's metal bracket, inserting the center or side outlet pipe into the thermostat's central cavity, replacing the bracket, and tightening the screws. This method is clearly complex and inefficient. While it's possible to directly use thermostats with center or side outlets, this would require producing multiple models, which would be inconvenient for manufacturers and increase costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to design a thermostat to achieve a quick and convenient way to change the water outlet.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A thermostat with inlet and outlet water pipes includes an upper body, on which a water channel and an electrical circuit are provided. The water channel includes a lower inlet water pipe, a horizontal inlet water pipe, a horizontal return water pipe, and an upper inlet water pipe, wherein the lower inlet water pipe is connected to the horizontal inlet water pipe, and the upper inlet water pipe is connected to the horizontal return water pipe.

[0006] Preferably, a connecting pipe is detachably connected to the transverse inlet pipe and the transverse return pipe to connect the two, and a one-way valve is provided at the outlet of the upper inlet pipe.

[0007] Preferably, the lower water inlet pipe and the upper water inlet pipe are on the same straight line and are separated from each other by a partition in the middle, and the horizontal water inlet pipe and the horizontal return pipe are arranged in parallel.

[0008] Preferably, the inlet portion of the lower water inlet pipe is provided with a silicone seal, and a movable ball is provided inside the lower water inlet pipe, which seals with the silicone seal when in contact with it.

[0009] Preferably, the inner wall of the lower water inlet pipe is provided with several vertically arranged limiting ribs, and a water flow channel is reserved between two adjacent limiting ribs. The several limiting ribs enclose a space with an inner diameter larger than the sphere, and the sphere moves up and down in the space, and the space is placed directly above the silicone seal.

[0010] Preferably, the partition, lower water inlet pipe, horizontal water inlet pipe, horizontal return pipe and upper water inlet pipe are all integral structures, and a spring is provided between the ball and the partition to elastically push the ball towards the silicone seal.

[0011] Preferably, the silicone sealant includes a body with a through channel running vertically through it. The upper and lower ends of the body are respectively provided with an upper sealing part and a lower sealing part. A pressure-reducing groove is provided around the upper sealing part of the body to provide deformation space when the upper part of the body is installed. The bottom surface of the depth of this pressure-reducing groove is lower than the lower plane of the center hole end of the upper sealing part.

[0012] Preferably, the pressure-reducing groove is an annular groove with an opening at the top of the main body.

[0013] Preferably, the upper sealing part protrudes upward and has a conical surface with an upward opening diameter that gradually increases, and the lower sealing part is one or more annular ribs provided on the inner wall of the channel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1-6 The figure shows a thermostat with inlet and outlet water pipes, including an upper body 1. The upper body 1 is provided with a water channel 2 and an electrical circuit. The electrical circuit is prior art and is not related to the technical problem to be solved in this application, so it will not be described in detail here. In this embodiment, it is worth noting that the water channel 2 includes a lower water inlet pipe 21, a horizontal water inlet pipe 22, a horizontal return pipe 23, and an upper water inlet pipe 24. The lower water inlet pipe 21 is connected to the horizontal water inlet pipe 22, and the upper water inlet pipe 24 is connected to the horizontal return pipe 23. In this embodiment, the lower water inlet pipe 21, the horizontal water inlet pipe 22, the horizontal return pipe 23, and the upper water inlet pipe 24 are in an F-shaped structure. A connecting pipe 25 is detachably connected to the horizontal water inlet pipe 22 and the horizontal return pipe 23 to connect the two. The outlet of the upper water inlet pipe 24 is provided with a one-way valve 3. When the water outlet method needs to be changed, if side water outlet is required, simply connect the water inlet end of the kettle to the horizontal water inlet pipe 22; if center water outlet is required, connect the connecting pipe 25 to connect the horizontal return pipe 23 to the horizontal water inlet pipe 22. In this embodiment, the connecting pipe 25 is a U-shaped pipe.

[0026] In this embodiment, the lower water inlet pipe 21 and the upper water inlet pipe 24 are on the same straight line and are separated from each other by a partition 26. The partition 26, the lower water inlet pipe 21, the transverse water inlet pipe 22, the transverse return pipe 23 and the upper water inlet pipe 24 are all integral structures. The transverse water inlet pipe 22 and the transverse return pipe 23 are arranged in parallel. The water pipe is integrally structured, which is convenient for production and has a simple structure. The invention objective of this application can be achieved at low cost. The structural cost is almost no increase compared to the two traditional water inlet methods. It can be shared and does not require the design of two products, reducing many troubles, such as not needing to open two sets of molds or store them separately.

[0027] In this embodiment, a silicone seal 4 is provided at the inlet of the lower water inlet pipe 21, and a movable ball 5 is provided inside the lower water inlet pipe 21. The ball 5 and the silicone seal 4 are in a sealing fit when in contact. The silicone seal 4 includes a main body with a through channel running vertically through it. An upper sealing part 41 and a lower sealing part 42 are respectively provided at the upper and lower ends of the main body. A pressure-reducing groove 43 is provided around the upper sealing part 41 of the main body to provide deformation space when the upper part of the main body is installed. The bottom surface of the pressure-reducing groove 43 is lower than the lower plane of the center hole 44 end of the upper sealing part 41. The pressure-reducing groove 43 is an annular groove with an opening at the upper part of the main body. The pressure-reducing ring groove relieves the pressure when the seal is assembled with the water inlet pipe cavity, ensuring that the sealing port of the silicone seal 4 will not deform, thereby achieving a more reliable sealing effect.

[0028] In a further embodiment, the upper sealing part 41 protrudes upward and has a tapered shape with an upwardly gradually increasing opening diameter. The lower sealing part 42 consists of one or more annular ribs on the inner wall of the channel. The upward protrusion of the upper sealing part 41 ensures that even if the silicone sealing ring undergoes some deformation during installation, it will not affect the upper sealing part 41, further guaranteeing that the upper sealing part 41 will not deform when it contacts and seals with the steel ball.

[0029] In this embodiment, the inner wall of the lower water inlet pipe 21 is provided with several vertically arranged limiting ribs 211. A water flow channel is reserved between two adjacent limiting ribs 211. The limiting ribs 211 enclose a space with an inner diameter larger than that of the sphere 5. The sphere 5 can move up and down in this space without excessive horizontal shaking. This space is located directly above the silicone seal 4. A spring 6 is provided between the sphere 5 and the partition 26 to elastically push the sphere 5 towards the silicone seal 4. The spring 6 is located in the space enclosed by the limiting ribs 211. One end of the spring 6 abuts against the sphere 5, and the other end abuts against the partition 26. In this embodiment, water flows out from the gap formed by the limiting ribs 211. In this embodiment, the upper sealing part 41 of the silicone seal 4 extends into the space enclosed by the limiting ribs 211. Since the sphere 5 can only move up and down, it will fall precisely at the upper sealing part 41 of the silicone seal 4 each time it falls, ensuring that the sphere 5 does not deviate and cause leakage.

[0030] In this embodiment, the one-way valve 3 is umbrella-shaped and includes a connecting part 31 and a sealing part 32. The connecting part 31 is fastened to the water outlet 7 at the upper water inlet pipe 24. The sealing part 32 of the one-way valve 3 is made of flexible material, and in this embodiment, it is made of silicone. In its normal state, the edge of the sealing part 42 is sealed with the water outlet 7. When water is supplied, the water pressure pushes the sealing part 32 to release water. In this embodiment, when the water supply stops, the one-way valve 3 has a certain elasticity, and the water pressure above the one-way valve 3 causes the one-way valve 3 to automatically return to the drooping state of the sealing part 32, thus achieving self-sealing.
