Description

Technical Field

[0001] This utility model relates to the field of hot water supply equipment technology, and in particular to a control module and a heat pump water heater. Background Technology

[0002] Heat pump water heaters work on a principle very similar to air conditioners. They use a small amount of electricity to drive a compressor, which compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous state. The gaseous refrigerant then enters the condenser to release heat and heat the water. The high-pressure liquid refrigerant passes through the expansion valve and absorbs heat in the evaporator to evaporate into a gaseous state, then returns to the compressor. This cycle continues, heating the water to 50°C to 65°C.

[0003] Heat pump water heaters are equipped with a control module to facilitate the control of their operating status. In existing technology, the control module includes a control box, an electronic control board housed within the control box, and a protective cover. The protective cover and control box are hinged together via a hinge shaft, meaning they employ a flip-top design. Due to the presence of the hinge shaft, a sealing strip is required between the protective cover and the control box to improve sealing. However, adding a sealing strip increases assembly steps, thus affecting assembly efficiency. Utility Model Content

[0004] The first technical problem solved by this utility model is to provide a control module that effectively solves the problem that existing control modules with flip-top designs and added sealing strips increase assembly steps and affect assembly efficiency.

[0005] The second technical problem solved by this utility model is to provide a heat pump water heater that effectively solves the problem that the existing control module adopts a flip-top design, and the addition of a sealing strip increases the assembly process and affects assembly efficiency.

[0015] In one embodiment, a first limiting structure is provided on the first connecting portion located on the left and right sides of the control box, and the first limiting structure on the left side and the first limiting structure on the right side are symmetrically arranged.

[0016] The ribs on the left and right sides of the protective cover are provided with second limiting structures, and the second limiting structure on the left side is symmetrically arranged with the second limiting structure on the right side.

[0017] In one embodiment, at least two first limiting structures are provided on the left and right sides along the vertical direction of the control box, wherein at least one first limiting structure is provided near the upper side and at least another first limiting structure is provided near the lower side.

[0018] Along the vertical direction of the protective cover, at least one second limiting structure is provided on the left and right sides respectively, with the second limiting structure located closer to the lower side;

[0022] Alternatively, the first limiting structure and the second limiting structure can be magnetic structures.

[0023] In one embodiment, the outer wall of the protective cover is provided with a handle.

[0024] The second technical problem mentioned above is solved by the following technical solution:

[0047] The following is combined with Figures 1 to 13 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, a control module is provided, including a control box 1 and a protective cover 2. An electronic control board is disposed inside the control box 1. A first connecting part 101 is provided on the outer side wall of the control box 1, extending from the left side of the control box 1, over the upper side of the control box 1, and to the right side of the control box 1. A second connecting part 201 is provided on the inner side wall of the protective cover 2, corresponding to the first connecting part 101, extending from the left side of the protective cover 2, over the upper side of the protective cover 2, and to the right side of the protective cover 2. The control box 1 and the protective cover 2 are slidably connected through the first connecting part 101 and the second connecting part 201. One of the first connecting part 101 and the second connecting part 201 is a groove, and the other is a rib. The rib is inserted into the groove.

[0049] By providing continuous first connecting portions 101 on the left, right, and top sides of the outer wall of the control box 1, and continuous second connecting portions 201 on the left, right, and top sides of the inner wall of the protective cover 2, and by providing a sliding connection between the control box 1 and the protective cover 2 through the first connecting portions 101 and the second connecting portions 201, the protective cover 2 can be opened and closed by sliding the protective cover 2, making the operation simple. At the same time, by setting one of the first connecting portions 101 and the second connecting portions 201 as a groove and the other as a rib, with the rib extending into the groove, the rib and the groove can seal the gap between the control box 1 and the protective cover 2. Therefore, the combination of the rib and the groove can have the dual functions of a slide rail and a seal, so that the structure of the protective cover 2 and the control box 1 can achieve a seal without the need for a separate sealing strip, simplifying the assembly process and improving assembly efficiency.

[0050] like Figure 1 As shown, the protective cover 2 and the control box 1 are in a closed state. In actual operation, the protective cover 2 is installed from top to bottom. The groove serves as an internal slide rail and works with the rib to achieve precise assembly, ensuring the structural stability of the installation of the protective cover 2 and the control box 1.

[0051] like Figure 2 As shown, the protective cover 2 and the control box 1 are in the open state. In actual operation, the protective cover 2 is opened by sliding upwards. The operator only needs to make a simple sliding motion to fully expose the control box 1 and achieve quick operation.

[0052] like Figure 3 and Figure 4 As shown, the first connecting portions 101 located on the left and right sides of the control box 1 both extend from the upper side of the control box 1 to the lower side of the control box 1. This arrangement allows for smoother drainage. As an alternative implementation, the first connecting portions 101 located on the left or right side of the control box 1 may extend from the upper side of the control box 1 to the lower side of the control box 1.

[0053] Specifically, the first connecting portion 101 is a groove, and the second connecting portion 201 is a rib. Of course, in other embodiments, the first connecting portion 101 may be a rib, and the second connecting portion 201 may be a groove.

[0054] like Figure 1 and Figure 2 As shown, the control box 1 has an outward convex design relative to the installation object, with continuous grooves on the left, upper and right sides. The groove depth can be set to 2mm-2.5mm. Of course, in other embodiments, the groove depth can also be set to other specific values, which are not limited here.

[0055] Since the rib and the groove work together to achieve a sealing effect, the length of the rib can be specifically set to 2mm-2.5mm, that is, the length of the rib is matched with the depth of the groove, so that when the rib is inserted into the groove, it can completely seal the groove and improve the sealing effect. Of course, in other embodiments, the length of the rib can also be set to other specific values, which are not limited here.

[0056] In one embodiment, a first transition fillet 2011 is provided on the lower side of the second connecting portion 201 located on the left and right sides of the protective cover 2, specifically as follows: Figure 9 As shown. Since the protective cover 2 will be installed from top to bottom onto the control box 1, the first transition rounded corner 2011 located on the lower side of the protective cover 2 can serve as a guide, facilitating the installation of the protective cover 2.

[0057] Specifically, the size of the first transition fillet 2011 can be set to R5mm-R8mm. Of course, in other embodiments, it can also be adjusted according to actual needs.

[0058] like Figure 3 and Figure 4 As shown, the lower side of the first connecting part 101 located on the left and right sides of the control box 1 is provided with a second transition rounded corner 1012. The second transition rounded corner 1012 is correspondingly set with the first transition rounded corner 2011. In this way, when the protective cover 2 is installed and in the closed state with the control box 1, the lower sides of the first connecting part 101 and the second connecting part 201 can be fully engaged, resulting in a better sealing effect. At the same time, after the protective cover 2 is installed into the control box 1, it needs to slide upward to the open state. Since the second transition rounded corner 1012 is correspondingly set with the first transition rounded corner 2011, it can prevent the mismatch between the lower sides of the control box 1 and the protective cover 2 from causing the protective cover 2 to slide and get stuck, thus ensuring that the protective cover 2 slides smoothly.

[0059] To ensure sealing and aesthetics, a third transition fillet is provided on the upper side of the first connecting part 101 located on the left and right sides of the control box 1. The cooperation between the third transition fillet and the first transition fillet 2011 can also ensure that the protective cover 2 is accurately aligned along the fillet during installation, reducing assembly difficulty.

[0060] Correspondingly, a fourth transition rounded corner is provided on the upper side of the second connecting part 201 located on the left and right sides of the protective cover 2. When the protective cover 2 and the control box 1 are in a closed state, the fourth transition rounded corner matches the third transition rounded corner, which can also make the sealing effect between the protective cover 2 and the control box 1 better, and at the same time improve the aesthetics.

[0061] like Figure 7 and Figure 8As shown, the protective cover 2 includes a cover body 202 and an extension 204. One end of the extension 204 is connected to the cover body 202, and the other end of the extension 204 extends toward the side close to the control box 1 and is connected to one end of the rib. The other end of the rib is embedded in the groove.

[0062] In one embodiment, a first limiting structure 1011 is provided on the first connecting portion 101 located on the left and right sides of the control box 1, and a second limiting structure 2012 is provided on the protruding ribs located on the left and right sides of the protective cover 2. The first limiting structure 1011 and the second limiting structure 2012 are connected in cooperation to limit the sliding position of the protective cover 2 and the control box 1. As an alternative embodiment, the first limiting structure 1011 may be provided on the first connecting portion 101 located on the left or right side of the control box 1, and the second limiting structure 2012 may be provided on the protruding ribs located on the left or right side of the protective cover 2.

[0063] Specifically, the first limiting structure 1011 on the left side of the control box 1 is symmetrically arranged with the first limiting structure 1011 on the right side; the second limiting structure 2012 on the left side of the protective cover 2 is symmetrically arranged with the second limiting structure 2012 on the right side. By symmetrically arranging the first limiting structure 1011 and the second limiting structure 2012 on the left and right sides respectively, the limiting effect when the protective cover 2 is assembled with the control box 1 is better, and it is easier to assemble in place, avoiding the situation where one side may not be able to limit the movement.

[0064] In one embodiment, along the vertical direction of the control box 1, there are two first limiting structures 1011 on the left and right sides respectively, one of which is located near the upper side and the other is located near the lower side.

[0065] Along the vertical direction of the protective cover 2, there is a second limiting structure 2012 on the left and right sides respectively, with the second limiting structure 2012 located near the lower side;

[0066] When the protective cover 2 and the control box 1 are in the open state, the second limiting structure 2012 is connected to the first limiting structure 1011 located near the upper side.

[0067] When the protective cover 2 and the control box 1 are in a closed state, the second limiting structure 2012 is connected to the first limiting structure 1011 located near the lower side.

[0068] Since the protective cover 2 is installed from top to bottom, when the second limiting structure 2012 engages with the first limiting structure 1011 located near the lower side, it indicates that the protective cover 2 is installed in place and the protective cover 2 and control box 1 are in a closed state. At this time, the engagement of the first limiting structure 1011 and the second limiting structure 2012 forms a horizontal limit, ensuring the structural stability in the closed state. At this time, the rib and the groove are fully engaged, improving the sealing performance of the protective cover 2 and control box 1. When it is necessary to operate the control box 1, the protective cover 2 can be slid upward. When the second limiting structure 2012 engages with the first limiting structure 1011 located near the upper side, it indicates that the protective cover 2 is opened in place and the protective cover 2 and control box 1 are in an open state. The engagement of the first limiting structure 1011 and the second limiting structure 2012 forms a horizontal limit, preventing the protective cover 2 from sliding down under gravity or sliding excessively upward.

[0069] As an alternative implementation, the first limiting structure 1011 provided on the left and right sides along the vertical direction of the control box 1 may be three, four or more; and the second limiting structure 2012 provided on the left and right sides along the vertical direction of the protective cover 2 may be two or more.

[0070] like Figure 10 As shown, the first limiting structure 1011 is a mounting hole, and the second limiting structure 2012 is a protrusion. Alternatively, in a different implementation, the first limiting structure 1011 can be a protrusion, and the second limiting structure 2012 can be a mounting hole.

[0071] Of course, in other embodiments, the first limiting structure 1011 and the second limiting structure 2012 can both be magnetic structures. Specifically, the magnetic structure is a magnet, which can be a magnet embedded in the protrusion and groove, and magnetically connected only by the exposed part. Alternatively, the magnet can be combined with the protrusion and the mounting hole, such as one of the magnets being set in the form of a protrusion, and the mounting hole containing a magnet that magnetically attracts the protrusion. No further restrictions are imposed here.

[0072] like Figure 6 and Figure 8 As shown, the outer wall of the protective cover 2 is provided with a handle 203. One end of the handle 203 is connected to the protective cover 2, and the other end extends away from the protective cover 2. Specifically, the handle 203 is located on the front of the protective cover 2 and near the lower side of the protective cover 2, thereby facilitating operation. By providing the handle 203, it is convenient for the operator to slide the protective cover 2 from bottom to top or install the protective cover 2 from top to bottom. As an alternative implementation, the protective cover 2 may not have a handle 203, or the handle 203 may be located in other positions on the protective cover 2.

[0073] In specific settings, the maximum width of the handle 203 extending away from the protective cover 2 can be 15mm-18mm, which makes it easy for the operator to hold and operate the protective cover 2 with one hand. Of course, other values ​​are also possible, and no further restrictions are imposed here.

[0074] The handle 203 and the protective cover 2 are made of one piece with chamfered edges, which ensures operation comfort and avoids potential risks to the operator from sharp edges.

[0075] According to an embodiment of the present invention, another aspect is provided: a heat pump water heater, including a water heater body 3, wherein the aforementioned control module is provided on the casing of the water heater body 3.

[0076] The heat pump water heater has a control module installed on the housing of the water heater body 3. The protective cover 2 is opened by sliding upwards. The operator can fully expose the control box 1 with a simple sliding action, which enables quick operation. When the protective cover 2 is installed on the control box 1, the protective cover 2 can accurately return to its original position along the groove of the control box 1 to ensure structural stability.

[0077] The protective cover 2 has continuous raised ribs on its left, upper and right sides, which serve the dual functions of a slide rail and a sealing strip. When the protective cover 2 and the control box 1 are in a closed state, the raised ribs and the grooves on the control box 1 can fit tightly to form a sealing ring, effectively preventing external intrusion such as rainwater and dust.

[0078] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0079] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
