Description

Technical Field

[0001] This utility model relates to the field of heating unit technology, and in particular to an electrical control installation structure and a three-generation heating unit. Background Technology

[0002] A tri-generation heating and cooling unit is a highly integrated, multi-functional heat pump system that combines air conditioning, underfloor heating, and domestic hot water supply into one unit. A single system can comprehensively meet users' heating, cooling, and hot water needs in different seasons and scenarios. In both tri-generation heating and air conditioning units, the electrical control system plays a crucial role, precisely coordinating the operation of all components within the unit to ensure continuous, efficient, and stable operation.

[0003] In existing tri-generation heating and air conditioning units, the electrical control system mainly includes an electrical control box and indoor unit boards, outdoor unit boards, and drive boards assembled within the control box. For example, Chinese patent document CN202410477846.8 discloses an electrical control structure including a first electrical control box and a second electrical control box. The first electrical control box houses the drive board, and the second electrical control box houses the indoor unit board. Typically, the wiring between the indoor unit board and the drive board is pre-installed at the manufacturing plant, while the wiring of the indoor unit board needs to be done during user installation of the unit.

[0004] However, the electrical control box used to install the indoor unit board is equipped with a cover, and the electrical control box is installed inside the unit's enclosure. Before wiring the indoor unit board, the user needs to open the side panel and cover of the enclosure in sequence, making the wiring operation relatively complicated.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0034] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0035] Please see Figures 1 to 3The first aspect of this utility model provides an electrical control installation structure, including an electrical control box 1, an inner unit board 5 mounting plate 2, an outer unit board 3, a drive board 4, and an inner unit board 5.

[0036] Specifically, the mounting plate 2 for the indoor unit board 5 is used to install the indoor unit board 5, and the mounting plate 2 is vertically fixed on one side of the electrical control box 1. The indoor unit board 5 is installed on the side of the mounting plate 2 facing away from the electrical control box 1. The indoor unit board 5 can be electrically connected to the water flow sensor and inlet / outlet water temperature sensor of the three-generation heating unit (e.g., a three-generation heating unit) for water circuit monitoring. The outdoor unit board 3 and the drive board 4 are installed inside the electrical control box 1. The outdoor unit board 3 can be electrically connected to the high and low pressure switches, electronic expansion valve, and refrigerant leakage sensor of the three-generation heating unit for refrigerant circuit monitoring. The drive board 4 is used to control the motor, compressor motor, etc. of the three-generation heating unit.

[0037] Furthermore, the electrical control installation structure also includes a side panel 6, a cover plate 7, and a terminal block 8. Specifically, the side panel 6 is part of the tri-generation heating unit housing, participating in the assembly of the tri-generation heating unit housing. The side panel 6 has a wiring port 61 located on the front side of the inner unit board 5. When the electrical control box 1 is installed inside the unit (i.e., the unit housing), the inner unit board 5 is located within the wiring port 61. The cover plate 7 is located on the outside of the side panel 6 and covers the wiring port 61. When the cover plate 7 covers the wiring port 61, it provides waterproofing and dustproofing. When the cover plate 7 is removed from the wiring port 61, it allows for wiring of the inner unit board 5. The terminal block 8 is installed on the inner unit board 5 for connecting external cables.

[0038] As can be seen, this utility model, by opening a wiring port 61 on the side panel 6 of the enclosure and providing a cover plate 7 at the wiring port 61, allows the indoor unit board 5 to be directly protected by the cover plate 7 on the side panel 6 after it is placed in the wiring port 61, thus eliminating the need for a cover inside the enclosure to protect the indoor unit board 5. Before wiring the indoor unit board 5, the user only needs to open the cover plate 7 on the side panel 6 of the enclosure to connect the wiring, making wiring more convenient.

[0039] like Figure 2 and Figure 3 As shown, in an optional embodiment, the cover plate 7 is connected to the outer side of the housing side plate 6 by screws, thereby facilitating the installation and removal of the cover plate 7. A handle 9 is provided on the cover plate 7. The handle 9 can be vertically positioned on the outer side of the cover plate 7, but is not limited to this arrangement. The handle 9 can be a strip-shaped grip groove on the outer side of the cover plate 7, or it can be a U-shaped handle. After the screws are removed from the cover plate 7, the user can easily move the cover plate 7 by gripping the handle 9, thereby improving the ease of maintenance of the unit.

[0040] like Figure 2 As shown, in an optional embodiment, the cover plate 7 includes a covering portion 71 and a mounting portion 72 surrounding the covering portion 71. The mounting portion 72 may be annular and is connected to the outer side of the housing side plate 6 by screws. The lower part of the mounting portion 72 protrudes outward from the housing side plate 6 to form a cable limiting groove 721. The opening of the cable limiting groove 721 faces the indoor unit panel 5. After the cable is connected to the terminal block 8, the cable is led downward through the cable limiting groove 721 to the outside of the unit housing, and then connected to the user's power supply. The cable limiting groove 721 can restrain the cable, ensuring a reliable connection between the cable and the terminal block 8, and enabling the three-phase heating unit to operate normally.

[0041] like Figure 1 As shown, in an optional embodiment, the electrical control mounting structure further includes a filter board 10; the filter board 10 is mounted on the drive board 4. Compared to the method of installing the filter board 10 separately in the electrical control box 1, mounting the filter board 10 on the drive board 4 can reduce the volume of the electrical control box 1, which helps to reduce the volume of the unit. In order to achieve normal power supply to the external unit board 3, the filter board 10, and the drive board 4, and to ensure that the filter board 10 can suppress electromagnetic interference and protect sensitive devices, specifically, the external unit board 3 is electrically connected to the internal unit board 5, the filter board 10 is electrically connected to the terminal block 8, and the drive board 4 is electrically connected to the filter board 10.

[0042] like Figure 2 , Figure 4 as well as Figure 5 As shown, in an optional embodiment, a first elastic retaining member 11 is fixedly provided on the side of the mounting plate 2 of the indoor unit board 5 away from the electrical control box 1; the four corners of the indoor unit board 5 are provided with locking holes 51 that cooperate with the first elastic retaining member 11. It can be understood that the number of first elastic retaining members 118 is the same as the number of locking holes 5151.

[0043] Specifically, the first elastic retaining member 11 includes a first limiting part 111 arranged parallel to the mounting plate 2 of the interior panel 5, an insertion part 112 arranged perpendicular to and connected to the first limiting part 111, and two inclined elastic pressing blocks 113 mirror-imagely disposed at the head end of the insertion part 112. The first limiting part 111 is located on the back side of the interior panel 5; the insertion part 112 is horizontally inserted through the card hole 51; the two inclined elastic pressing blocks 113 form a V-shape and are located on the front side of the interior panel 5. When the two inclined elastic pressing blocks 113 are not pressed, the inclined elastic pressing blocks 113 can cooperate with the first limiting part 111 to limit the interior panel 5, so that the interior panel 5 cannot move back and forth in the horizontal direction due to the limitation of the multiple first elastic retaining members 11.

[0044] When it is necessary to remove the indoor unit board 5 from the first elastic retaining member 11, the maintenance personnel can press the two inclined elastic blocks 113 with two fingers, so that the two inclined elastic blocks 113 close towards the insertion part 112. The inclined elastic blocks 113 can pass through the locking hole 51, thereby ensuring that the indoor unit board 5 can be smoothly removed from the insertion part 112.

[0045] like Figure 4 and Figure 5 As shown, in an optional embodiment, a structural reinforcing seat 114 is formed on the side of the first limiting part 111 opposite to the indoor unit plate 5; the structural reinforcing seat 114 includes a first reinforcing part 1141, a second reinforcing part 1142, and a third reinforcing part 1143; the first reinforcing part 1141 is parallel to the mounting plate 2 of the indoor unit plate 5 and is fixedly mounted on the mounting plate 2 of the indoor unit plate 5; the second reinforcing part 1142 is vertically mounted on the first reinforcing part 1141 and is connected to the first limiting part 111; the third reinforcing part 1143 is symmetrically arranged on both sides of the second reinforcing part 1142 and is connected to the first limiting part 111. Since the indoor unit plate 5 and the electrical components mounted on the indoor unit plate 5 have a certain weight, when the indoor unit plate 5 is vertically mounted on the electrical control mounting plate and held and supported by the first elastic retaining member 11, the first elastic retaining member 11 is required to have high structural strength. In order to achieve the above objectives, this embodiment provides a structural reinforcement seat 114 on the back side of the first limiting part 111, thereby improving the structural strength and mechanical properties of the first elastic retaining member 11, so that the first elastic retaining member 11 is not easily damaged or broken during long-term use.

[0046] like Figure 4 and Figure 5 As shown, in an optional embodiment, the first elastic retaining member 11 further includes a second limiting part 115 horizontally arranged and connected to the first reinforcing part 1141, a third limiting part 116 vertically arranged and connected to the second limiting part 115, and an elastic pulling part 117 horizontally arranged and connected to the third limiting part 116; the third limiting part 116 is an elastic limiting part; the second limiting part 115 is used to limit the top and bottom of the interior panel 5; the third limiting part 116 abuts against the front side of the interior panel 5 (the front side refers to the side of the interior panel 5 away from the mounting plate 2 of the interior panel 5), and can cooperate with the first limiting part 111 to strengthen the limiting effect on the interior panel 5 in the horizontal direction. The elastic pulling part 117 can be pulled towards the front side of the interior panel 5, which can release the limiting effect of the third limiting part 116 on the interior panel 5, making it convenient for maintenance personnel to remove the interior panel 5.

[0047] It is understood that the various parts of the first elastic retaining member 11 can be integrally formed, and the first elastic retaining member 11 is a plastic elastic part.

[0048] like Figure 4 and Figure 5 As shown, in an optional embodiment, a second elastic retaining member 12 is fixed on the side of the mounting plate 2 of the indoor unit board 5 away from the electrical control box 1. The second elastic retaining member 12 is located between the upper and lower first elastic retaining members 11, and specifically includes an I-shaped limiting seat 121 and a retaining structure 122 connected to the I-shaped limiting seat 121.

[0049] The retaining structure 122 includes a stepped elastic block 1221 and a pressing block 1222 connected to the elastic block 1221. The pressing block 1222 presses against one side of the indoor unit plate 5 at an angle, and the elastic block 1221 is connected to the I-shaped limiting seat 121. Through the joint limiting of the elastic block 1221 and the I-shaped limiting seat 121, the indoor unit plate 5 is further prevented from moving back and forth, so that the indoor unit plate 5 can be firmly installed on the indoor unit plate 5 mounting plate 2, avoiding the indoor unit plate 5 from falling down and damaging the core components of the tri-generation heating unit such as the compressor and liquid storage tank, while reducing safety hazards.

[0050] like Figures 1 to 3 As shown, a second aspect of this utility model also provides a tri-generation heating and cooling unit, including the aforementioned electrical control installation structure. In the electrical control installation structure, the bottom of the electrical control box 1 is fixedly installed on the top of the fan bracket inside the unit housing. Compared with existing tri-generation heating and cooling units, the heating and cooling unit provided by this utility model has the advantage of simple user wiring.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
