[0039] In order to solve the problem that the control panel on the heat pump water heater is easily disturbed by water in rain or mist, resulting in that the heat pump water heater cannot continuously and normally operate, the utility model provides an electric control box and heat pump water heater.

[0040] The embodiments of the utility model will be described below in combination with Figures 1 to 10 .

[0041] On the one hand, as shown in Figure 2 , Figure 3 and Figure 9 , the electric control box of the embodiments of the utility model is installed on the heat pump water heater, and the electric control box comprises a protective cover plate 1 and a box body 2.

[0042] Specifically, one side of the protective cover plate 1 facing the box body 2 is provided with an annular baffle 101, and one side of the box body 2 facing the protective cover plate 1 is provided with a control panel 201 and a recess around the periphery of the control panel 201, when the annular baffle 101 is covered on the control panel 201, the end of the annular baffle 101 abuts against the bottom surface of the recess.

[0043] In the embodiments, the annular baffle 101 matched with the recess around the periphery of the control panel 201 is arranged on the protective cover plate 1, so that the protective cover plate 1 can be covered on the outer surface of the control panel 201 to form a protection structure for the control panel 201. In addition, the end of the annular baffle 101 abuts against the bottom surface of the recess, which can isolate the control panel 201 from the external environment, so that the control panel 201 is in a relatively closed space, preventing water vapor from directly contacting the control panel 201 through the protective cover plate 1, reducing the possibility of control panel 201 failure caused by environmental factors, and ensuring the stable operation of the electric control system of the heat pump water heater.

[0044] It should be noted that the control panel 201 in the embodiments can be a physical button or a touch screen, or a combination of a physical button and a touch screen. The utility model does not make specific limitation thereon. It can be understood that when the control panel 201 is provided with a touch screen, the touch screen will display the operating parameters of the heat pump water heater. Therefore, in order to facilitate the operator to observe the related information on the screen, such as Figure 8As shown, a visible window corresponding to the screen can be arranged on the protective cover plate 1, or the protective cover plate 1 is made of transparent material. As an example, the visible window is arranged on the protective cover plate 1, and the annular baffle 101 surrounds the periphery of the visible window.

[0045] Further, as shown, Figures 3 to 6 The recess is a groove or a first lap step 202, and the annular baffle 101 abuts against the bottom of the groove or the first lap step 202. Specifically, when the recess is a groove, the abutting position of the annular baffle 101 is lower than the surface of the control panel 201, so that even if the water vapor breaks through the initial defense line of the annular baffle 101, the water vapor will not directly contact the control panel 201, but will accumulate in the groove.

[0046] When the recess is the first lap step 202, it can be located at the edge of the shell, so that an L-shaped corner is formed at the edge of the shell, and the horizontal surface of the L-shaped corner, i.e., the first lap step 202, is lower than the surface of the control panel 201. Therefore, after the end of the annular baffle 101 abuts against the first lap step 202, the annular baffle 101 can not only block the water vapor, but also the vertical surface of the L-shaped corner can block the water vapor that breaks through the defense line of the annular baffle 101, so that the control panel 201 can stably operate in a relatively clean and dry environment.

[0047] In addition, whether the recess is a groove or a first lap step 202, as long as the recess is arranged on the periphery of the control panel 201, the placement position of the annular baffle 101 on the box body 2 can be determined, so that the operator can complete the matching positioning operation of the annular baffle 101 and the recess in a short time, and reduce the time consumed in debugging.

[0048] It can be understood that in the subsequent use process, there are cases that the protective cover plate 1 needs to be opened to maintain the control panel 201 or change the working state of the heat pump water heater by using the control panel 201. Therefore, in order to improve the convenience of opening the protective cover plate 1, one side of the protective cover plate 1 can be hinged to the box body 2, so that it can be flexibly rotated around the hinge point. Similarly, when the protective cover plate 1 is connected to the box body 2 in a hinged manner, the operator can easily restore the protective cover plate 1 in the opened state to the original closed state.

[0049] Further, to ensure that the protective cover plate 1 can effectively resist the invasion of water vapor to the control panel 201 in the closed state, the side of the protective cover plate 1 away from the hinge of the protective cover plate 1 can be clamped with the box body 2. In this way, the protective cover plate 1 can be stably covered on the box body 2, reducing the possibility of accidental opening due to accidental vibration, shaking or other external force interference. At the same time, it also reduces the difficulty of the operator to open the protective cover plate 1, so that the operator can complete the maintenance work of the control panel 201 in a short time.

[0050] As shown in the examples, Figure 2 The hinge of the protective cover plate 1 and the shell 5 is located on the left side of the shell 5, and the clamping of the protective cover plate and the shell 5 is located on the right side of the shell 5. When the protective cover plate 1 needs to be opened, the operator applies force in the counterclockwise direction, and with the help of the rotation of the hinge point, the protective cover plate 1 can be smoothly opened. After the corresponding work is completed, the protective cover plate 1 is pushed in the clockwise direction to make it abut and clamp with the clamping on the right side of the shell 5, so that the closing of the protective cover plate 1 can be realized. This operation process conforms to the principle of ergonomics, which can effectively reduce the learning cost of the operator and enable him to operate more quickly.

[0051] In one embodiment, as shown in Figure 3 , Figure 5 and Figure 6 The hinge side of the box body 2 is provided with a second lap step 203, one of the second lap step 203 and the protective cover plate 1 is provided with a hinge shaft 3, and the other is provided with an arc-shaped buckle 4 which is hingedly connected with the hinge shaft 3. The cooperation mode of the hinge shaft 3 and the arc-shaped buckle 4 can realize flexible rotary connection while reducing the difficulty of structure assembly and disassembly of the hinge of the box body 2 and the protective cover plate 1.

[0052] Specifically, the side of the arc-shaped buckle 4 facing the hinge shaft 3 is provided with an opening suitable for the hinge shaft 3. Therefore, during assembly, only the opening of the arc-shaped buckle 4 needs to be aligned with the hinge shaft 3, and the two can be easily clamped together without complex operation steps or the help of special tools, effectively improving the assembly efficiency and shortening the assembly time. When the protective cover plate 1 needs to be disassembled, the hinge shaft 3 can also be conveniently removed from the opening to quickly separate the protective cover plate 1 from the box body 2. Preferably, the arc-shaped buckle 4 is shaped as a 3 / 4 circular arc and is made of a material with a certain elastic deformation.

[0053] In one embodiment, as shown in Figure 9As shown, the side of the protective cover plate 1 facing the box body 2 is also provided with a ring-shaped flange 102 surrounding the ring-shaped baffle 101, and a space for mounting the arc-shaped buckle 4 is formed between the ring-shaped flange 102 and the ring-shaped baffle 101; the ring-shaped flange 102 is provided with a relief gap 1021 at a position corresponding to the hinge shaft 3. By providing the ring-shaped flange 102 on the protective cover plate 1, the structural strength of the protective cover plate 1 can be increased, and the possibility of deformation or damage of the protective cover plate 1 can be reduced.

[0054] Further, the ring-shaped flange 102 is provided with a relief gap 1021 at a position corresponding to the hinge shaft 3, which ensures that the hinge shaft 3 can be normally installed and smoothly play its rotating function, so that the opening and closing action of the protective cover plate 1 can be smoothly performed, and the overall structural layout is more reasonable and orderly, avoiding mutual interference between components.

[0055] In one embodiment, as shown in Figure 6 and Figure 10 , the arc-shaped buckle 4 is provided with a gap 401, and the central angle corresponding to the gap 401 is less than 180 degrees, and the hinge shaft 3 is clamped to the arc-shaped buckle 4 through the gap 401. By providing the gap 401 on the arc-shaped buckle 4, the difficulty of installation and disassembly of the hinge shaft 3 and the arc-shaped buckle 4 can be reduced, and the convenience of operation can be improved. Further, the central angle corresponding to the gap 401 is less than 180 degrees, which can prevent the connection from being unstable due to the size of the gap 401 being too large, and can also prevent the hinge shaft 3 from being unable to smoothly enter and exit the arc-shaped buckle 4 due to the size of the gap 401 being too small. Preferably, the central angle corresponding to the gap 401 is 90 degrees.

[0056] In one embodiment, as shown in Figure 9 , the number of arc-shaped buckles 4 is multiple pairs, and the multiple pairs of arc-shaped buckles 4 are arranged at intervals along the length direction of the protective cover plate 1, and each hinge shaft 3 is correspondingly provided with a pair of arc-shaped buckles 4. The multiple pairs of arc-shaped buckles 4 are arranged at intervals along the length direction of the protective cover plate 1, so that the connection of the protective cover plate 1 and the box body 2 at the hinge is more stable and uniform. Compared with the case of a single or small number of arc-shaped buckles 4, the multiple pairs of arc-shaped buckles 4 can share the force generated during the opening and closing process of the protective cover plate 1 from different positions, effectively disperse stress, avoid problems such as loose connection and deformation due to excessive local stress, and greatly enhance the stability of the protective cover plate 1 during rotation, ensuring that it can realize the opening and closing action smoothly and for a long time.

[0057] In one embodiment, as shown in Figure 5 and Figure 7As shown, the annular baffle 101 is provided with a clamping portion 1011, one of the side walls of the clamping side of the box body 2 is provided with a groove portion 1012, and the other is provided with a protrusion portion 204 matched with the groove portion 1012. Through the clamping matching of the groove portion 1012 and the protrusion portion 204, the connection tightness of the protective cover plate 1 and the box body 2 in the closed state can be further enhanced. When the protective cover plate 1 is covered on the box body 2, the protrusion portion 204 is accurately embedded in the corresponding groove portion 1012, so that the protective cover plate 1 cannot be easily opened accidentally due to external interference factors such as vibration and shaking, effectively resisting the invasion of external water vapor, dust and other adverse factors on the control panel 201.

[0058] Further, as shown in the drawings, Figure 7 The annular baffle 101 is provided with a clamping portion 1011, one of the side walls of the clamping side of the box body 2 is provided with a groove portion 1012, and the other is provided with a protrusion portion 204 matched with the groove portion 1012. Through the clamping matching of the groove portion 1012 and the protrusion portion 204, the connection tightness of the protective cover plate 1 and the box body 2 in the closed state can be further enhanced. When the protective cover plate 1 is covered on the box body 2, the protrusion portion 204 is accurately embedded in the corresponding groove portion 1012, so that the protective cover plate 1 cannot be easily opened accidentally due to external interference factors such as vibration and shaking, effectively resisting the invasion of external water vapor, dust and other adverse factors on the control panel 201.

[0059] According to the embodiments of the utility model, on the other hand, as shown in the drawings, Figure 1 And Figure 2 As shown, the utility model further provides a heat pump water heater, which comprises a shell 5 and the above-mentioned electric control box.

[0060] Specifically, the shell 5 is provided with a mounting groove 502; the electric control box is mounted in the mounting groove 502, and a gap is left between the side wall of the opening side of the protective cover plate 1 and the groove wall of the mounting groove 502.

[0061] Compared with the existing heat pump water heater, the heat pump water heater provided with the above-mentioned electric control box can be beneficial to realize long-time stable operation. Specifically, by arranging the annular baffle 101 matched with the recessed portion of the control panel 201 on the protective cover plate 1, the protective cover plate 1 can be arranged on the outer surface of the control panel 201 to form a protection structure for the control panel 201. In addition, the end of the annular baffle 101 abuts against the bottom surface of the recessed portion, which can isolate the control panel 201 from the external environment, so that the control panel 201 is in a relatively closed space, preventing water vapor from directly contacting the control panel 201 through the protective cover plate 1, reducing the possibility of control panel 201 failure caused by environmental factors, and ensuring the stable operation of the electric control system of the heat pump water heater.

[0062] Further, after the end of the annular baffle 101 of the protective cover plate 1 abuts against the bottom surface of the groove portion 1012 located at the side of the control panel 201, the smaller size dust can also be effectively prevented from breaking through the protection of the protective cover plate 1 and contacting the control panel 201. Thus, by installing the above-mentioned electric control box, the failure rate of the heat pump water heater in the subsequent use process can be effectively reduced, and the long-term stable operation of the electric control system of the heat pump water heater is ensured.

[0063] In one embodiment, as shown in Figure 1 The outer surface profile of the protective cover plate 1 is adapted to the outer surface profile of the installation side 501. Such a setting makes the protective cover plate 1 and the shell 5 better integrated in appearance, and the integrity of the product side appearance is maintained.

[0064] In the specific content of the above specific embodiments, each technical feature can be combined arbitrarily without contradiction. In order to make the description simple, all possible combinations of the above technical features are not described, but as long as the combination of the technical features does not exist contradiction, it should be considered as the scope of the description.

[0065] The specific content of the above specific embodiments only expresses several embodiments of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the utility model. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
