Description

Technical Field

[0001] This utility model belongs to the field of temperature sensor technology, specifically relating to a waterproof temperature sensor device for dehumidifiers. Background Technology

[0002] Dehumidifiers, also known as moisture extractors, dryers, or dehumidifiers, are generally divided into two main categories: residential dehumidifiers and industrial dehumidifiers, and are a common component in air-conditioned homes. Typically, a dehumidifier consists of a compressor, heat exchanger, fan, water tank, casing, and controller. Its working principle is as follows: the fan draws humid air into the machine, where the heat exchanger cools the air, condensing water molecules into water droplets. The treated, dry air is then expelled from the machine, and this cycle continues to maintain a suitable relative humidity level indoors.

[0003] During the cooling process, the dehumidifier draws humid air into the radiator, where it is dried by cooling. During this process, water in the air condenses into droplets on the radiator surface. To determine if the dehumidifier is functioning properly, its cooling performance needs to be monitored, requiring a temperature sensor to monitor the radiator temperature. Existing temperature sensors typically have direct contact with the radiator, with epoxy resin encapsulating the sensor and its wires. Because the sensor is constantly exposed to the radiator's cooling range, thermal expansion and contraction can cause gaps to form between the epoxy resin and the sensor housing. When water comes into contact with this epoxy resin-encapsulated connection, it can seep into the interior of the epoxy resin encapsulation, specifically the connection between the sensor and its wires, potentially causing the sensor to malfunction. Therefore, a waterproof device for the temperature sensor is needed, and this invention addresses this technical problem. Utility Model Content

[0004] This invention provides a waterproof device for a temperature sensor in a dehumidifier, which can prevent the temperature sensor body and the part connected to the wires from coming into contact with water on the radiator, thereby preventing water on the radiator from affecting the operation of the temperature sensor.

[0005] A waterproof temperature sensor device for a dehumidifier includes a radiator and an opening slot formed on the radiator. One end of the temperature sensor body is connected to the opening slot, and the other end of the temperature sensor body is away from the radiator.

[0006] The temperature sensor body is connected to a waterproof mechanism, which includes an inner liner fitted on one end of the temperature sensor body, a first outer shell fitted on the outside of the inner liner, a connecting assembly connected to the first outer shell, and a second outer shell connected to the connecting assembly. The second outer shell is connected to a wire. The inner liner is used for waterproofing, and the first outer shell is used for draining water. The other end of the temperature sensor is connected to a heat sink.

[0007] Furthermore, the inner liner includes a sleeve fitted onto the temperature sensor body, a connector connected to one end of the sleeve, and an annular gasket connected to the other end of the sleeve. The connector and the annular gasket are respectively connected to both ends of the outer shell.

[0008] Furthermore, the outer shell is truncated cone-shaped with an inwardly concave arc shape on the side. Several drainage grooves are provided on the side of the outer shell, and a through groove is provided inside the outer shell. The through groove is connected to the sleeve. The connector abuts against the small end face of the outer shell, and the annular gasket abuts against the large end face of the outer shell. The large end face of the outer shell is connected to the connecting assembly.

[0009] Furthermore, the connector is frustum-shaped and communicates internally with the sleeve, with the large end face of the connector abutting against the small end face of the outer casing.

[0010] Furthermore, the connecting assembly includes an internally threaded sleeve connected to the large end face of the first housing and an externally threaded sleeve connected to the internally threaded sleeve, the externally threaded sleeve being connected to the second housing.

[0011] Furthermore, the outer shell 2 includes a hollow connecting shell, a through hole formed on the connecting shell, a plurality of sliding grooves formed on the connecting shell, a slider connected inside the sliding groove, and a plurality of movable plates connected inside the connecting shell. The plurality of movable plates are respectively connected to the plurality of sliders. The side of the movable plate is provided with a groove. The plurality of grooves form a connecting hole, and the wire is connected in the connecting hole.

[0012] Furthermore, the slider is connected to the connecting block, the connecting block has a threaded groove, and adjacent connecting blocks are connected by bolts.

[0013] The technical effects of this utility model are as follows:

[0014] (1) The heat sink in this solution has an opening slot, which facilitates the connection between the temperature sensor body and the heat sink. Moreover, the part where the temperature sensor body and the wire are connected does not contact the heat sink and is far away from the heat sink, thereby preventing the water on the heat sink from contacting the part where the temperature sensor body and the wire are connected, so that the temperature sensor body can work normally.

[0015] (2) The inner liner in this solution is installed on the body of the temperature sensor, which can prevent water on the radiator from flowing along the body of the temperature sensor to the location where it is connected to the wire. Moreover, the outer shell has a drainage function. After the water blocked by the inner liner comes into contact with the outer shell, it can flow along the outer shell to other directions. The second outer shell can prevent water from entering the wire. In addition, the combined action of the first outer shell, the connecting component and the second outer shell can protect the connection between the body of the temperature sensor and the wire, thus effectively achieving the waterproof function.

[0016] (3) The connector in this solution is truncated cone-shaped, which can guide water to a small end face of the outer shell. Moreover, several drainage grooves are opened on the side of the outer shell. So after the water comes into contact with the outer shell, it will flow into the drainage grooves, thus realizing the drainage function.

[0017] (4) The movable plate in this solution is located inside the connecting shell. When it is necessary to waterproof the wire part, the slider can be moved by the connecting block, and then the movable plate can be moved into the through hole. The movable plate will block the through hole, and the grooves on several movable plates will be combined to form a connecting hole. The connecting hole is connected to the wire, so the waterproof function is achieved by the movable plate and the connecting shell together. Attached Figure Description

[0028] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments and accompanying drawings.

[0029] Example 1

[0030] See Figures 1-2 A waterproof temperature sensor device for a dehumidifier includes a radiator 19 and an opening slot 20 formed on the radiator 19. One end of the temperature sensor body 1 is connected to the opening slot 20, and the other end of the temperature sensor body 1, i.e. the end connected to the wire 7, is away from the radiator 19.

[0031] The working process of this embodiment is as follows:

[0032] First, one end of the temperature sensor body 1 needs to be inserted into the opening slot 20. Then, the other end of the temperature sensor body 1, that is, the end connected to the wire 7, should be moved away from the heat sink 19 to prevent water on the heat sink 19 from contacting the other end of the temperature sensor body 1, so that the temperature sensor body 1 can work normally.

[0033] Example 2

[0034] See Figures 3-7 Based on Embodiment 1, this application also provides another embodiment, the specific contents of which are as follows: the temperature sensor body 1 is connected to a waterproof mechanism, the waterproof mechanism includes an inner liner fitted on one end of the temperature sensor body 1, an outer shell 3 fitted on the outside of the inner liner, a connecting component connected to the outer shell 3, and an outer shell 2 connected to the connecting component. The outer shell 2 is connected to the wire 7. The inner liner is used for waterproofing, the outer shell 3 is used for draining water, and the other end of the temperature sensor is connected to the heat sink 19.

[0035] Furthermore, the liner includes a sleeve 8 fitted onto the temperature sensor body 1, a connector 2 connected to one end of the sleeve 8, and an annular gasket 9 connected to the other end of the sleeve 8. The connector 2 and the annular gasket 9 are respectively connected to both ends of the outer shell 3. In this embodiment, the liner is made of rubber.

[0036] Furthermore, the outer shell 3 is frustum-shaped with inwardly concave arc sides. Several drainage grooves 4 are formed on the sides of the outer shell 3, and a through groove 10 is formed inside the outer shell 3. The through groove 10 connects to the sleeve 8. The connector 2 abuts against the small end face of the outer shell 3, and the annular gasket 9 abuts against the large end face of the outer shell 3. The large end face of the outer shell 3 connects to the connecting assembly. The connector 2 and the annular gasket 9 are respectively connected to both ends of the outer shell 3, thereby achieving the connection between the inner liner and the outer shell 3 and preventing the inner liner from falling out of the outer shell 3.

[0037] Furthermore, connector 2 is frustum shaped and its interior is connected to the sleeve, with the large end face of connector 2 abutting against the small end face of outer shell 3.

[0038] Furthermore, the connecting assembly includes an internally threaded sleeve 5 connected to the large end face of the outer casing 3, and an externally threaded sleeve 12 connected to the internally threaded sleeve 5, with the externally threaded sleeve 12 connected to the outer casing 2.

[0039] Furthermore, the outer shell 2 includes a hollow connecting shell 6, a through hole 11 formed on the connecting shell 6, a plurality of sliding grooves 14 formed on the connecting shell 6, a slider 13 connected inside the sliding groove 14, and a plurality of movable plates 17 connected inside the connecting shell 6. The plurality of movable plates 17 are respectively connected to the plurality of sliders 13. The side of the movable plate 17 is provided with a groove 18, and the plurality of grooves 18 form a connecting hole, in which the wire 7 is connected. In this embodiment, there are two movable plates 17, two sliders 13, and two sliding grooves 14.

[0040] Since the connecting shell 6 needs to be positioned where the wire 7 is located, and one end of the wire 7 is connected to the temperature sensor body 1 and the other end is connected to other devices, a through hole 11 is provided on the connecting shell 6 in this solution for easy installation. This allows the temperature sensor body 1 to pass through the through hole 11 and move the connecting shell 6 to the position where the wire 7 is located.

[0041] Furthermore, the slider 13 is connected to the connecting block 15, and the connecting block 15 has a threaded groove 16. Adjacent connecting blocks 15 are connected by bolts. The bolts are connected within the two threaded grooves 16.

[0042] In this embodiment, the external threaded sleeve 12 is fixed on the connecting shell 6, and the internal threaded sleeve 5 is fixed on the outer shell 3.

[0043] The working process of this embodiment is as follows:

[0044] First, pass the end of the temperature sensor body 1 through the through hole 11 of the connecting shell 6, so that the connecting shell 6 is located at the position of the wire 7. Then, pass the end of the temperature sensor body 1 through the inner sleeve. Then, move the outer shell 3 so that the outer shell 3 drives the inner liner to move on the temperature sensor body 1 until it is close to the position of the wire 7. Then, rotate the connecting shell 6 so that it drives the outer threaded sleeve 12 to rotate, so that the inner threaded sleeve 5 is connected to the outer threaded sleeve 12.

[0045] Next, the moving connecting block 15 is moved so that it drives the slider 13 to move in the slide groove 14. The slider 13 will drive the moving plate 17 to move into the through hole 11. When the two moving plates 17 move into the through hole 11, they will block the through hole 11. The connecting hole formed by the two grooves 18 can accommodate the wire 7. At this time, the distance between the two connecting shells 6 is relatively close. They can be connected to the two connecting blocks 15 by bolts to fix their position and prevent the two moving plates 17 from separating.

[0046] In this design, the connector 2 is shaped like a frustum. When there is water on the surface of the radiator 19 and the water flows along the temperature sensor body 1 to the connector 2, the connector 2 can guide the water to the small end face of the outer shell 3. Moreover, the side of the outer shell 3 is provided with several drainage grooves 4, so after the water comes into contact with the outer shell 3, it will flow into the drainage grooves 4 and flow out of the outer shell 3 along the drainage grooves 4, thereby further realizing the waterproof function.

[0047] The technical features not described in detail in this solution are based on the conventional operation and general understanding of those skilled in the art and are derived from existing technologies, and will not be elaborated further here.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
