[0040] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of the present disclosure.

[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0042] In the description of the present disclosure, it is necessary to understand that the orientation or positional relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0043] In the description of the present disclosure, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present disclosure.

[0044] In addition, the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0045] Figure 1-Figure 8 The water tank and the wire fixing device thereof of the present disclosure are exemplarily shown.

[0046] In electrical equipment such as water heaters and air conditioners, a temperature sensing package is usually installed to detect the temperature of the temperature-measured parts such as water tanks or evaporators.

[0047] Take air-energy water heater as an example.

[0048] An air-energy water heater is a water heater that heats water by absorbing heat from the air. Compared with electric water heaters, solar water heaters and gas water heaters, air-energy water heaters are safer and more efficient. When working, the outdoor unit of the air-energy water heater acts as a heat exchanger to absorb heat from the outdoor air, heat the refrigerant (low-boiling-point working fluid) and evaporate it. The refrigerant vapor is compressed and heated by the compressor and enters the water tank, transferring heat to the water in the water tank to increase the water temperature. The liquid refrigerant after heat release and condensation is then throttled and cooled, and then returns to the outdoor heat exchanger to enter the next cycle.

[0049] The housing 10 of the water tank 100 is usually provided with a temperature sensing package (not shown in the figure) to detect the water temperature. The number of temperature sensing packages is usually two or more. Different temperature sensing packages are arranged at different positions to detect the water temperature at different positions.

[0050] The temperature sensing package is a wired component, which has a wire 20 and is connected to the controller signal through the wire 20 to transmit the detection result to the controller, so that the controller can implement various control actions such as start and stop control according to the water temperature detection result. The wire 20 is usually a UL (Underwriters Laboratories Inc.) sheathed wire. The UL sheathed wire can be divided into different specifications such as 2-core, 4-core or 8-core.

[0051] The wire 20 of the temperature sensing package is generally fixed by a wire fixing device 30. The wire fixing device 30 is arranged on the housing 10 to install and fix the wire 20. The wire fixing device 30 is provided with a wire hole, and the wire 20 passes through the wire hole and is fixed by the wire fixing device 30. Since the water tank 100 is mostly installed in an outdoor environment, the wire hole needs to be sealed and waterproof to prevent external water from entering the housing 10 and affecting normal operation.

[0052] In the related art, the wire fixing device 30 is a locking joint type wire fixing device, which includes a rubber cover and a locking joint. The rubber cover is roughly in the shape of a whole disk. The locking joint is arranged at the center of the rubber cover. The wire passing hole is arranged at the center of the locking joint. When in use, the rubber cover is connected to the housing 10, and the wire 20 is directly passed through the wire passing hole.

[0053] The locking connector type wire fixing device has a specific wire fixing diameter range. If the locking connector is selected to be larger, the diameter of the wire hole is larger than the diameter of the wire 20, it is difficult to achieve a waterproof sealing effect, and it may even be impossible to effectively fix the wire 20. Therefore, the locking connector is generally selected to be smaller, so that the diameter of the wire hole is smaller than the diameter of the wire 20, so as to reliably fix the wire 20 and achieve a better waterproof sealing effect.

[0054] However, since the wire fixing device 30 in the related art adopts the method of allowing the wire 20 to pass directly through the wire hole, when the diameter of the wire hole is smaller than the diameter of the wire 20, it is more difficult to pass the wire 20 directly through the closed wire hole with a smaller aperture, and the wire fixing is more difficult, which makes it difficult to meet the requirements of different temperature sensing packages and wire fixing.

[0055] The combined routing of different temperature-sensing packages means that different temperature-sensing packages no longer use separate sheathed wires, but share one sheathed wire. For example, if a single temperature-sensing package uses a 2-core sheathed wire, then when two temperature-sensing packages are combined, the two temperature-sensing packages can use a 4-core sheathed wire, and the terminals of this 4-core sheathed wire are separately connected to the two temperature-sensing packages. When the routing is combined, the diameter of the wire 20 is relatively large. Therefore, when a locking joint type wire fixing device is used, it is more difficult to pass the wire 20 directly through a closed wire hole with a smaller aperture. Therefore, in the related art, the locking joint type wire fixing device is difficult to meet the needs of combining the routing of different temperature-sensing packages, and each temperature-sensing package can only be fixed using one locking joint type wire fixing device.

[0056] At the same time, in the related art, plug-in terminals cannot be used on wire 20. The plug-in terminal is a plug-in plastic shell connector, which is a terminal connector used for plug-in connection between various load terminals and lead wires. The plug-in terminal is sleeved on the outside of wire 20, and its outer dimensions are larger than the outer diameter of wire 20. If a plug-in terminal is used, the locking connector needs to be selected according to the plug-in terminal so that the plug-in terminal can pass smoothly. However, in this case, the diameter of the wire hole is larger than the outer diameter of wire 20, and there is a gap between the wire hole and wire 20, making it difficult to achieve a reliable sealing and fixing effect, and there is a risk of water ingress. Therefore, when a locking connector type wire fixing device is used, it is difficult to use the plug-in terminal.

[0057] In view of the above situation, the embodiment of the present disclosure improves the structure of the wire fixing device 30 .

[0058] Figure 2-8 The structure of the wire fixing device 30 of the present disclosure is exemplarily shown. Figure 2-8 The wire fixing device 30 provided in the embodiment of the present disclosure includes a main body 40. A wire passing hole 23 is provided on the main body 40. And the main body 40 has a first end 25 and a second end 26. The first end 25 and the second end 26 are detachably connected. When the first end 25 and the second end 26 are separated, an opening 24 is formed between the first end 25 and the second end 26, and the opening 24 is located on one radial side of the wire passing hole 23 and is connected to the wire passing hole 23, so that the wire 20 can enter the wire passing hole 23 through the opening 24. When the first end 25 and the second end 26 are combined, the opening 24 is closed, and the main body 40 fixes the wire 20 passing through the wire passing hole 23.

[0059] Based on the above arrangement, when the wire 20 is fixed by using the wire fixing device 30, the wire 20 can be placed into the wire passing hole 23 through the opening 24 when the first end 25 and the second end 26 are separated from each other, and then the first end 25 and the second end 26 are brought together to close the opening 24 and the wire passing hole 23, thereby fixing the wire 20.

[0060] Since the wire 20 no longer needs to pass directly through the wire hole 23, but can enter the wire hole 23 through the opening 24 located on the radial side of the wire hole 23, even if the diameter of the wire hole 23 is smaller than the diameter of the wire 20, the wire 20 can be easily installed and fixed without the problem of difficulty in inserting the wire 20 due to the diameter of the wire hole 23 being smaller than the diameter of the wire 20.

[0061] It can be seen that the wire fixing device 30 provided in the embodiment of the present disclosure can effectively reduce the difficulty of wire fixing and improve the wire fixing efficiency while achieving a better sealing and waterproofing effect.

[0062] When different temperature sensing packages need to be routed together, the thicker wire 20 can be placed into the wire hole 23 through the opening 24, and then the opening 24 is closed to complete the assembly of the wire 20 on the wire fixing device 30, and the wire fixing device 30 fixes the wire 20. For example, if two temperature sensing packages are routed together, and the terminals of a 4-core sheathed wire are separately connected to the two temperature sensing packages, then the 1 4-core sheathed wire can enter the wire hole 23 through the opening 24, and then the opening 24 and the wire hole 23 are closed to achieve the installation and fixation of the corresponding sheathed wire.

[0063] It can be seen that the wiring fixing device 30 provided in the embodiment of the present disclosure can meet the demand for merging the wiring of different temperature sensing packages, effectively solve the long-standing problem that two or more temperature sensing packages cannot be merged and fixed, and save costs.

[0064] At the same time, since the wire fixing device 30 provided in the embodiment of the present disclosure can reduce the dependence of the wire fixing sealing effect on the diameter size of the wire hole 23, it can also solve the problem that the plug-in terminal cannot be used in the related art. Based on the wire fixing device 30 of the embodiment of the present disclosure, when the plug-in terminal is needed, the diameter of the wire hole 23 of the wire fixing device 30 can still be selected according to the outer diameter of the wire 20, without having to be selected according to the size of the plug-in terminal. In this case, on the one hand, the diameter of the wire hole 23 is smaller than the outer diameter of the wire 20, which can achieve an effective sealing and fixing effect. On the other hand, the larger part due to the provision of the plug-in terminal can be conveniently passed through the opening 24, and it will not be difficult to pass through because the diameter of the wire hole 23 is smaller than the outer size of the plug-in terminal. Therefore, the use of the wire fixing device 30 provided in the embodiment of the present disclosure can make the use of the plug-in terminal possible without affecting the sealing effect, which is conducive to meeting the universal design requirements of the temperature sensing package.

[0065] It can be seen that by providing a detachably combined first end 25 and second end 26 on one side of the wire hole 23 of the main body 40, an openable and closable opening 24 is formed on one side of the wire hole 23, so that the wire fixing device 30 can reliably fix the wire and effectively seal, and the difficulty of fixing the wire is relatively low, which is conducive to reducing costs and improving efficiency.

[0066] The detachable connection between the first end 25 and the second end 26 may be a snap fit. Figure 6 In some embodiments, one of the first end 25 and the second end 26 is provided with a convex portion 28, and the other is provided with a concave portion 29, and the convex portion 28 and the concave portion 29 are engaged. In this way, the detachable connection between the first end 25 and the second end 26 can be conveniently achieved by engaging the convex portion 28 and the concave portion 29. Moreover, after the wire 20 is inserted into the wire hole 23, the convex portion 28 and the concave portion 29 are engaged, which can achieve a good sealing effect and effectively prevent water from entering.

[0067] In addition, in order to improve the sealing and waterproofing effect, in some embodiments, the diameter of the wire hole 23 is 1-2 mm smaller than the diameter of the wire 20. When the wire 20 is placed into the wire hole 23 from the opening 24 and the opening 24 is closed, the wire hole 23 is closed to become a closed circular hole with a diameter smaller than the diameter of the wire 20. Since the diameter of the wire hole 23 is 1-2 mm smaller than the diameter of the wire 20, the closed circular wire hole 23 can fit tightly with the circular wire 20 to effectively seal and waterproof.

[0068] Next, the structure of the main body 40 is further introduced.

[0069] See also Figure 2-7 In some embodiments, the main body 40 includes a base 1 and a wire fixing member 2 .

[0070] The base 1 is generally in the shape of a disk, and is used to connect with the housing 10 to achieve the connection between the wire fixing device 30 and the water tank 100. Figure 4 and Figure 5 In some embodiments, a buckle 4 is provided on the base 1, and the base 1 is buckled and connected to the housing 10 via the buckle 4. Figure 4 and Figure 5 In some embodiments, a connecting hole 13 is provided on the base 1, and the base 1 is connected to the shell 10 through the connecting hole 13. Threaded connectors such as screws pass through the connecting hole 13 and the corresponding holes on the shell 10 to fasten the base 1 and the shell 10 together. Specifically, in some embodiments, connecting holes 13 are provided on both sides of the width direction of the opening 24, and the connecting holes 13 on both sides of the opening 24 are symmetrically arranged, so that a more stable and firm connection between the base 1 and the shell 10 can be achieved. When the buckle 4 and the connecting hole 13 are provided on the base 1 at the same time, the buckle 4 and the connecting hole 13 can be located on the upper and lower sides of the wire hole 23. For example, the buckle 4 is located on the upper side of the wire hole 23, and the connecting hole 13 is located on the lower side of the wire hole 23, so that the upper and lower parts of the base 1 can be connected to the shell 10 through the buckle 4 and the connecting hole 13 respectively, so that the base 1 can be reliably fixed on the shell 10. During installation, refer to Figure 1 The upper buckle 4 can be inserted into the upper part of the shell 10, and the lower part can be screwed through the connecting hole 13 to fix the base 1 on the shell 10.

[0071] The wire fixing member 2 is arranged on the base 1. The wire hole 23, the first end 25 and the second end 26 are located on the wire fixing member 2. When the convex portion 28 and the concave portion 29 are provided on the main body 40, the convex portion 28 and the concave portion 29 are also located on the wire fixing member 2. At this time, the wire hole 23 and the opening 24 are both located on the wire fixing member 2. When fixing the wire, the opening or closing of the opening 24 can be controlled by moving the two ends of the wire fixing member 2 (i.e., the first end 25 and the second end 26) closer to or farther from each other, thereby facilitating the wire 20 to enter the wire hole 23 through the opening 24, and facilitating the wire 20 to be sealed and fixed by the wire fixing member 2 after entering the wire hole 23 by combining the two ends of the wire fixing member 2.

[0072] Among them, the wire fixing member 2 and the base 1 can be a split structure, so that the wire fixing member 2 and the base 1 are made of different materials. For example, in some embodiments, the wire fixing member 2 is an elastic member made of an elastic material (such as rubber); the base 1 is an injection molded part made of plastic. The wire fixing member 2 is set as an elastic member such as a rubber member, so that the elastic deformation characteristics of the wire fixing member 2 can be utilized to conveniently realize the opening and closing of the opening 24, as well as the sealing and waterproof effect after the opening 24 is closed. The base 1 is set as an injection molded part, so that the main body 40 has a certain hardness, which is conducive to improving the overall hardness of the wire fixing device 30 and facilitating the connection between the base 1 and the shell 10. When the wire fixing member 2 is an elastic member and the base 1 is an injection molded part, the base 1 can play a certain supporting role for the wire fixing member 2 with a smaller hardness, which is convenient for separating and retracting the first end 25 and the second end 26, so as to conveniently control the opening or closing of the opening 24.

[0073] When the base body 1 and the wire fixing member 2 adopt a split structure, the two need to be connected. As an exemplary connection method between the base body 1 and the wire fixing member 2, the base body 1 and the wire fixing member 2 are embedded with each other and bonded with glue.

[0074] See also Figure 2-7 The base 1 is provided with a fitting hole 11 and a fitting opening 12. The fitting hole 11 is located at the center of the base 1 and is roughly circular. The fitting opening 12 extends from the fitting hole 11 to the outer edge of the base 1, forming a long strip-shaped gap with an open end on the base 1. At this time, the fitting opening 12 is located on one radial side of the fitting hole 11 and communicates with the fitting hole 11.

[0075] The wire fixing member 2 includes a head 21 and an arm 22 connected to each other. The head 21 is roughly annular, and a wire hole 23 is provided in the center thereof, so that the wire hole 23 is arranged on the head 21. The wire hole 23 is roughly circular. The arm 22 extends outward from the head 21 to form a long arm-like structure. The middle of the arm 22 is divided into two, forming a first end 25 and a second end 26 that can approach and move away from each other, so that the first end 25 and the second end 26 are located on the arm 22, and the opening 24 that can be opened and closed is located on the arm 22. The opening 24 extends from one end of the arm 22 close to the wire hole 23 to the other end of the arm 22 away from the wire hole 23, so that the opening 24 forms a long strip opening located on the arm 22.

[0076] When mated with the base 1, the head 21 is inserted into the fitting hole 11, and the arm 22 is inserted into the fitting opening 12. Figure 7 and Figure 2 It can be known that, in some embodiments, the periphery of the head 21 and the arm 22 is provided with a groove 27, and the head 21 and the arm 22 are engaged with the base 1 through the groove 27. In this way, the base 1 and the wire fixing member 2 are engaged with each other.

[0077] During assembly, the wire fixing member 2 can be placed in the fitting hole 11 and the fitting opening 12 of the base 1, so that the head 21 is located in the fitting hole 11, the arm 22 is located in the fitting opening 12, and the wall of the base 1 located in the fitting hole 11 and the fitting opening 12 along the thickness direction is embedded in the groove 27 of the wire fixing member 2, so that the base 1 and the wire fixing member 2 are fitted with each other. It can be understood that the thickness direction of the base 1 is also the direction of the base 1 from the side surface close to the housing 10 to the side surface away from the housing 10.

[0078] After the base body 1 and the wire fixing member 2 are fitted together, strong glue can be injected into the fitting portion of the two to stick the wire fixing member 2 onto the base body 1 , thereby achieving an adhesive connection between the base body 1 and the wire fixing member 2 .

[0079] By gluing the base 1 and the wire fixing member 2 together, a relatively firm connection between the two can be achieved, and the gap between the two can be sealed to prevent water from entering the joint between the two, thus playing a certain waterproof sealing role.

[0080] In addition, in order to improve the sealing and waterproof effect of the wire fixing device 30, see Figure 2-3 as well as Figure 8 In some embodiments, the wire fixing device 30 includes a sealing ring 5, which is sleeved on the outer ring of the main body 40. In this way, the outer ring of the main body 40 and the housing 10 can be sealed by the sealing ring 5, so that a tighter seal between the wire fixing device 30 and the housing 10 is achieved.

[0081] Specifically, when the main body 40 includes the base 1 and the wire fixing member 2, the sealing ring 5 can be sleeved on the outer ring of the base 1 to form a sealing fit between the outer ring of the base 1 and the shell 10 to prevent water from entering the gap between the outer ring of the base 1 and the shell 10.

[0082] The sealing ring 5 may be a rubber ring, and the outer ring profile thereof may be an arc shape that fits the outer shape of the housing 10 to achieve a better sealing effect.

[0083] When in use, the line 20 can be inserted into the line hole 23, and after the opening 24 is closed, the sealing ring 5 can be sleeved on the outer ring of the main body 40 to make the sealing ring 5 fit with the shell 10 to form a seal. This can prevent the sealing ring 5 from affecting the expansion and contraction between the first end 25 and the second end 26, making it easier for the opening 24 to open and close.

[0084] Also, see Figure 3 In some embodiments, the main body 40 is provided with a lug 3, which protrudes from the surface of the main body 40 facing the housing 10 toward one side of the housing 10, and the wire clamping groove 31 is provided on the lug 3. Specifically, the lug 3 is provided on the base 1, and is specifically located on the surface of the base 1 facing the housing 10. The surface of the base 1 provided with the lug 3 is recessed toward the side away from the housing 10 relative to the other parts of the surface of the base 1 facing the housing 10, which is conducive to reducing the size of the wire fixing device 30 along the thickness direction of the base 1 due to the provision of the lug 3, so that the overall structure of the wire fixing device 30 is more flat and compact.

[0085] The main body 40 is provided with a wire clamping groove 31, and the wire 20 is clamped into the wire clamping groove 31. The wire clamping groove 31 has a restraining effect on the wire 20 on the basis of the wire through hole 23, so that the wire 20 can be more reliably fixed and the wire fixing effect can be further improved. During the wire fixing process, the wire 20 can first pass through the wire clamping groove 31 and then pass through the wire through hole 23. At this time, the wire clamping groove 31 is located upstream of the wire through hole 23 along the wiring direction.

[0086] Among them, Figure 3 As shown, in some embodiments, the length direction of the wire clamping groove 31 is arranged at an angle to the axial direction of the wire through hole 23. For example, in some embodiments, the length direction of the wire clamping groove 31 is perpendicular to the axial direction of the wire through hole 23. It can be understood that the length direction of the wire clamping groove 31 is the extension direction of the wire clamping groove 31, and is also the direction in which the wire 20 passes through the wire clamping groove 31.

[0087] Since the length direction of the wire clamping groove 31 is not parallel to the axial direction of the wire passing hole 23 but has an angle thereto, the wire 20 needs to turn when extending from the wire clamping groove 31 to the wire passing hole 23. For example, when the length direction of the wire clamping groove 31 is perpendicular to the axial direction of the wire passing hole 23, the wire 20 will turn 90° after passing through the lateral constraint of the wire clamping groove 31 and then pass through the wire passing hole 23. In this way, a certain anti-pulling effect can be played to prevent the wire fixing member 2 from loosening when the wire 20 is pulled by an external force.

[0088] In summary, the wire fixing device 30 provided in the embodiment of the present disclosure can achieve a reliable wire fixing and sealing effect based on a relatively simple and compact structure, and the wire fixing difficulty is relatively low. It can conveniently realize the integrated and combined routing of two or more temperature sensing packages, thereby reducing costs and improving efficiency.

[0089] Of course, the wire fixing device 30 provided in the embodiment of the present disclosure can be used not only in the water heater to install and fix the wire 20 of the temperature sensing package on the water tank 100, but also in other electrical equipment, for example, it can also be used to install and fix the wire 20 of the temperature sensing package in the air conditioner, and even the wire 20 fixed by the wire fixing device 30 is not limited to the wire of the temperature sensing package, but can also be the wire of other wired components. In fact, the wire fixing device 30 provided in the embodiment of the present disclosure is suitable for various occasions with similar sealing and fixing requirements as the temperature sensing package of the water tank of the water heater.

[0090] The above description is only an exemplary embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
