Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning equipment, and in particular to an installation structure for an electric heating component of a cabinet air conditioner. Background Technology

[0002] The indoor unit of a cabinet air conditioner is typically equipped with an electric heating element to assist in heating in low-temperature environments, thereby improving the overall heating capacity and efficiency of the unit. An air duct is formed inside the indoor unit casing, within which the evaporator and electric heating element are sequentially arranged. Indoor air enters through the air duct inlet, flows through the evaporator and electric heating element for heat exchange, and then exits through the air duct outlet.

[0003] Currently, the common installation and fixing structure is as follows: an upper water tray is installed at the top of the evaporator to collect condensate generated by the condensate pipes in the air duct; a lower water tray is installed at the bottom of the evaporator to collect condensate flowing down from the upper water tray and the evaporator surface, and discharges the condensate to the outside through a drain outlet. The electric heating element is installed between the upper and lower water trays, with its top end fixedly connected to the upper water tray and its bottom end fixedly connected to the lower water tray. This method of fixing at both ends provides support for the electric heating element, preventing it from tilting or shifting due to airflow or vibration during operation, thus ensuring the reliability of the product to a certain extent.

[0004] However, as market demands for air conditioning performance continue to rise, increasing heat exchange efficiency and air volume requires enlarging the air inlet area of ​​the duct. This is typically achieved by lengthening the air inlet and correspondingly increasing the length of the evaporator, inevitably increasing the installation distance between the upper and lower water trays. With existing mounting methods, electric heating components of matching length must be replaced simultaneously; existing or other length electric heating components are incompatible. This not only increases material costs but also prevents the electric heating components from being universally compatible. Utility Model Content

[0005] To address the technical problem of poor versatility of electric heating components in existing installation structures, this utility model provides an installation structure for electric heating components in cabinet air conditioners.

[0006] The technical solution adopted by this utility model to solve its technical problem is: An installation structure for an electric heating component of a cabinet air conditioner includes a housing. Inside the housing, an upper water tray, an evaporator, and a lower water tray are arranged vertically in sequence. The electric heating component and the evaporator are arranged side-by-side at intervals in the front-to-back direction. A support assembly is provided inside the housing. The support assembly includes a support member and a support beam. Along the width direction of the evaporator, the support member is located on both sides of the evaporator. Multiple mounting positions are spaced apart along the length direction of the evaporator on the support member. The support beam is detachably mounted on the mounting positions and can be switched between multiple mounting positions. A mounting part is provided on either the upper or lower water tray. The electric heating component has a first end and a second end arranged opposite to each other. The first end of the electric heating component is connected to the mounting part, and the second end of the electric heating component is connected to the support beam.

[0007] Furthermore, the upper water receiving pan has a clearance opening that extends through the upper and lower surfaces of the upper water receiving pan. The second end of the electric heating component can be inserted into the housing through the clearance opening and detachably connected to the support beam. The first end of the electric heating component is detachably connected to the mounting part of the upper water receiving pan.

[0008] Furthermore, the support component is provided with multiple threaded holes at intervals along the length of the evaporator, and the end of the support beam is provided with a corresponding mating hole. The threaded holes and the mating holes are aligned and fastening screws are inserted through them. The tail of the fastening screw is threaded into the threaded hole, and the head of the fastening screw presses against the end of the support beam.

[0009] Furthermore, the support member has a rearwardly extending straight portion, the distal end of which is bent toward the side closer to the evaporator to form a bent portion, and the evaporator is at least partially overlapped on the bent portion.

[0010] Furthermore, the inner wall of the housing is provided with mounting steps, the bent part overlaps the mounting steps, and is connected by screws or bolts.

[0011] Furthermore, a plug hole is provided in the middle of the support beam, and a positioning pin is provided at the second end of the electric heating component. The positioning pin is inserted into the plug hole, and the first end of the electric heating component is connected to the mounting part by screws or bolts.

[0012] Furthermore, the lower end face of the upper water receiving tray is provided with a first mounting hole and a downwardly extending first positioning rib. The first mounting hole penetrates the lower end face and the upper end face of the upper water receiving tray. The support member is provided with a second mounting hole and a first positioning hole. The first positioning rib is inserted into the first positioning hole. The first mounting hole and the second mounting hole are aligned. The second mounting hole is a threaded hole and also includes a first screw. The tail of the first screw passes through the first mounting hole and is threadedly connected to the second mounting hole. The head of the first screw presses against the upper end face of the upper water receiving tray.

[0013] Furthermore, the upper water receiving tray has multiple drainage holes that penetrate the upper and lower surfaces of the upper water receiving tray.

[0014] Furthermore, the upper surface of the lower water receiving tray is provided with an upwardly extending second positioning rib, and the support member is provided with a corresponding second positioning hole. The lower water receiving tray is provided with a third mounting hole on both the left and right sides, and the support member is provided with a corresponding fourth mounting hole on both the left and right sides. The second positioning rib is inserted into the second positioning hole, and the third mounting hole is aligned with the fourth mounting hole. The fourth mounting hole is a threaded hole and also includes a second screw. The tail of the second screw passes through the third mounting hole and is threadedly connected to the fourth mounting hole. The head of the second screw presses against the side of the lower water receiving tray.

[0015] Furthermore, it also includes fixing screws and at least one connecting block, one side of which is connected to the support member by fixing screws, and the other side of which is connected to the evaporator by fixing screws.

[0016] The beneficial effects of this utility model are: 1. This utility model, by setting support members on both sides of the evaporator and opening multiple installation positions on the support members at intervals along the length of the evaporator, allows the support beam to flexibly select and fix the installation position according to the actual size of the electric heating component. This structure changes the traditional installation method, separating the installation structure of the electric heating component from the upper and lower water receiving trays. The lower water receiving tray only needs to perform its inherent water receiving and drainage functions, and the installation distance between the upper and lower water receiving trays is no longer related to the length of the electric heating component. This eliminates the need to replace the electric heating component with a specially made extended type when increasing the size of the evaporator or lengthening the air duct to improve performance, greatly improving design flexibility and significantly reducing material and cost expenses caused by model changes.

[0017] 2. By creating a clearance opening through the upper and lower surfaces of the upper water receiving pan, the second end of the electric heating element can be inserted into the housing through the clearance opening and detachably connected to the support beam. The first end of the electric heating element is detachably connected to the mounting part of the upper water receiving pan. This design eliminates the need to disassemble the upper water receiving pan when replacing or removing the electric heating element. Simply disconnect the electric heating element from the mounting part and from the support beam to pull it out. This saves time and effort during installation and removal, improving efficiency.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0020] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1 to 7 This utility model provides an installation structure for the electric heating component of a cabinet air conditioner.

[0023] The electric heating element 5 is generally rectangular, strip-shaped, or metal tubular. The electric heating element 5 has a first end and a second end that are arranged opposite to each other. Taking the rectangular shape as an example, it is usually composed of many PTC ceramic heating elements and aluminum heat dissipation fins that are alternately stacked and assembled in a metal frame. Current passes through the PTC ceramic elements to make them heat up, and the heat is quickly conducted to the aluminum fins that are in close contact. The air blown by the fan flows through these dense fin gaps and is thus heated efficiently.

[0024] like Figures 1 to 3 As shown, in some embodiments, an installation structure for an electric heating component of a cabinet air conditioner is provided, including a housing 1. An upper water tray 2, an evaporator 3, and a lower water tray 4 are sequentially arranged vertically inside the housing 1. An electric heating component 5 is arranged parallel to the evaporator 3 at intervals along the front-to-back direction. A support assembly is provided inside the housing 1, including a support member 6 and a support beam 7. Along the width direction of the evaporator 3, the support member 6 is disposed on both sides of the evaporator 3. Multiple mounting positions 8 are spaced apart along the length direction of the evaporator 3 on the support member 6. The support beam 7 is detachably mounted on the mounting positions 8 and can switch positions among the multiple mounting positions 8. A mounting portion is provided on either the upper water tray 2 or the lower water tray 4. The electric heating component 5 has a first end and a second end arranged opposite to each other. The first end of the electric heating component 5 is connected to the mounting portion, and the second end of the electric heating component 5 is connected to the support beam 7.

[0025] The first end of the electric heating component 5 is connected to the mounting part, and the second end of the electric heating component 5 is connected to the support beam 7. This connection can be a direct connection or an indirect connection. As for the connection form, it can be a fixed connection or a detachable connection, such as welding, screws, bolts or clips.

[0026] The support member 6 can be a long, straight support shell plate, one located on the left side of the evaporator 3 and the other on the right side of the evaporator 3. The support member 6 is generally connected to the inner wall of the shell 1 with screws, or it can be fixed with bolts or welding. In addition, the support member 6 can also be a support frame, support frame or support block, etc. The shape of the support member 6 is not particularly limited here, as long as the support member 6 has multiple mounting positions 8 spaced apart along the length of the evaporator 3 for the installation of the support beam 7, and the support member 6 can be fixed inside the shell 1.

[0027] like Figures 1 to 4As shown, the support member 6 is used to support and fix the evaporator 3. Regarding how the support member 6 fixes the evaporator 3, the evaporator 3 can be directly fixed to the support member 6 with screws, or it can be indirectly fixed to the support member 6. For example, it also includes fixing screws and at least one connecting block 24. One side of the connecting block 24 is connected to the support member 6 by fixing screws, and the opposite side of the connecting block 24 is connected to the evaporator 3 by fixing screws. In addition, a bent portion 11 can be provided on the support member 6, which serves two purposes: supporting the evaporator 3 and acting as a mounting ear for fixed connection with the housing 1. Specifically, the support member 6 has a rearwardly extending straight portion 10, and the distal end of the straight portion 10 is bent towards the side close to the evaporator 3 to form the bent portion 11. The evaporator 3 at least partially overlaps the bent portion 11. An installation step 12 is provided on the inner wall of the housing 1, and the bent portion 11 overlaps the installation step 12 and is connected by screws or bolts. The proximal extension of the straight portion 10 may be provided with a flange that bends toward one side of the housing 1. The flange may overlap the housing 1 and may be fixed by welding, screws or bolts.

[0028] like Figures 1 to 3 As shown, the support member 6 is also used to support and fix the support beam 7. Regarding how the support member 6 provides multiple mounting positions 8 for installing the support beam 7, optionally, multiple mounting holes are provided at intervals along the length of the evaporator 3 on the support member 6, and corresponding mating holes are provided at the ends of the support beam 7. The two are aligned and can be detachably connected by screws or bolts. Alternatively, multiple slots can be provided at intervals along the length of the evaporator 3 on the support member 6, and corresponding protrusions can be provided at the ends of the support beam 7, with the protrusions engaging with the slots. Alternatively, multiple mounting positions 8 can be provided at intervals along the length of the evaporator 3 on the support member 6, and the support beam 7 and the support member 6 can be fixed by external connectors, such as clamps or cable ties.

[0029] A mounting part is provided on either the upper water tray 2 or the lower water tray 4, and the first end of the electric heating component 5 is connected to the mounting part. The mounting part can have screw holes opened on the upper water tray 2 or the lower water tray 4, and a through hole opened on the first end of the electric heating component 5. The through hole is aligned with the screw holes, and screws are passed through for fixation. Alternatively, the mounting part can use an existing clamping mechanism, such as two clamping blocks. By tightening the nuts of the bolts, the two clamping blocks are brought closer together to clamp and fix the first end of the electric heating component 5. Alternatively, a slot can be opened on the upper water tray 2 or the lower water tray 4, and a corresponding locking block is provided on the first end of the electric heating component 5. The locking block engages with the slot.

[0030] The configuration described above allows the support beam 7 to be flexibly positioned and fixed according to the actual size of the electric heating component 5. This structure changes the traditional installation method, separating the installation structure of the electric heating component 5 from the upper water tray 2 and the lower water tray 4. The lower water tray 4 only needs to perform its inherent water inlet and outlet functions, and the installation distance between the upper water tray 2 and the lower water tray 4 is no longer related to the length of the electric heating component 5. This eliminates the need to replace the electric heating component 5 with a specially made extended type when increasing the size of the evaporator 3 or lengthening the air duct 25 to improve performance, greatly improving design flexibility and significantly reducing material and cost expenses caused by model changes.

[0031] like Figures 4 to 5 As shown, to further improve the efficiency and convenience of assembling and disassembling the electric heating component 5, this embodiment provides a clearance opening 9 through the upper and lower surfaces of the upper water receiving pan 2. The second end of the electric heating component 5 can be inserted into the housing 1 through the clearance opening 9 and detachably connected to the support beam 7. The first end of the electric heating component 5 is detachably connected to the mounting part of the upper water receiving pan 2. The clearance opening 9 can be located in the middle of the upper water receiving pan 2 or at the edge. For the mounting part, threaded holes can be provided around the clearance opening 9, and a through hole can be provided at the first end of the electric heating component 5. The two can be detachably connected by screws. Alternatively, an additional mounting structure can be provided on the upper water receiving pan 2, such as a mounting bracket or mounting protrusion, with corresponding threaded holes, and detachably connected by screws. In addition, the mounting part can be a slot provided on the upper water receiving pan 2, and a locking protrusion provided at the first end of the electric heating component 5, which can be detachably engaged. The second end of the electric heating element 5 can be inserted into the housing 1 through the clearance opening 9 and detachably connected to the support beam 7. One method involves an insertion hole 13 in the middle of the support beam 7, with a corresponding positioning pin 14 at the second end of the electric heating element 5. The positioning pin 14 is inserted into the insertion hole 13, and the first end of the electric heating element 5 is connected to the mounting part by screws or bolts, achieving positioning and detachable connection. Alternatively, a positioning groove can be opened on the support beam 7, with the second end of the electric heating element 5 abutting against the groove, or other feasible detachable connection methods can be used. The detachable connection of both the first and second ends of the electric heating element 5 is designed for quick assembly and disassembly.

[0032] like Figure 1 As shown, in some embodiments, the support member 6 is provided with a plurality of threaded holes at intervals along the length of the evaporator 3, and the end of the support beam 7 is provided with a corresponding mating hole. The threaded holes and the mating holes are aligned and fastening screws are inserted through them. The tail of the fastening screw is threadedly engaged with the threaded hole, and the head of the fastening screw presses against the end of the support beam 7.

[0033] like Figure 1As shown, in some embodiments, the upper water receiving tray 2 can be fixed by directly screwing or snapping it onto the inner wall of the housing 1, or it can be fixed onto the support member 6. For example, a first mounting hole 15 and a downwardly extending first positioning rib 16 are provided on the lower end face of the upper water receiving tray 2. The first mounting hole 15 penetrates the lower end face and the upper end face of the upper water receiving tray 2. The support member 6 is provided with a second mounting hole 17 and a first positioning hole 18. The first positioning rib 16 is inserted into the first positioning hole 18. The first mounting hole 15 and the second mounting hole 17 are aligned. The second mounting hole 17 is a threaded hole and also includes a first screw. The tail of the first screw passes through the first mounting hole 15 and is threadedly connected to the second mounting hole 17. The head of the first screw presses against the upper end face of the upper water receiving tray 2. The first mounting hole 15 is set on the end face, which makes it easier for installers to install screws from top to bottom and provides a more suitable installation angle. In addition, the first positioning rib 16 is inserted into the first positioning hole 18 for pre-positioning the water tray 2, which conveniently aligns the first mounting hole 15 with the second mounting hole 17, making it easier to install screws.

[0034] like Figure 5 As shown, in some embodiments, the upper water receiving tray 2 has multiple drainage holes 19 penetrating the upper and lower surfaces of the upper water receiving tray 2. The multiple drainage holes 19 can be evenly distributed on the upper water receiving tray 2, or they can be arranged at intervals along the left-right direction. The drainage holes 19 are used to collect condensate from the air duct 25 and to cool the evaporator 3.

[0035] like Figure 1 and Figure 6 As shown, the lower water tray 4 can be fixed by screwing or snapping it directly onto the inner wall of the housing 1, or it can be fixed to the support member 6. For example, the upper end face of the lower water tray 4 has an upwardly extending second positioning rib 20, and the support member 6 has a corresponding second positioning hole 21. The lower water tray 4 has third mounting holes 22 on both the left and right sides, and the support member 6 has corresponding fourth mounting holes 23 on both the left and right sides. The second positioning rib 20 is inserted into the second positioning hole 21. The third mounting hole 22 and the fourth mounting hole 23 are aligned. The fourth mounting hole 23 is a threaded hole and also includes a second screw. The tail of the second screw passes through the third mounting hole 22 and is threaded into the fourth mounting hole 23. The head of the second screw presses against the side of the lower water tray 4. Here, the fourth mounting hole 23 is set on the left and right sides of the support member 6 to facilitate the installation of the lower water tray 4. If the fourth mounting hole 23 were set on the lower end face of the lower water tray 4, the installer would need to squat down and face upwards to install the screw, making the installation more difficult. The second positioning rib 20 is inserted into the second positioning hole 21 for pre-positioning the lower water tray 4, and the third mounting hole 22 and the fourth mounting hole 23 are aligned to facilitate the installation of screws.

[0036] Reference Figure 7 As shown, this utility model includes two centrifugal fans 26 and two air ducts 25 inside the cabinet air conditioner. One air duct 25 guides air through the evaporator 3 and the electric heating component 5 for heat exchange, and then the air is discharged from the top of the cabinet air conditioner and enters the room. The other air duct 25 guides air through the evaporator 3 and the electric heating component 5 for heat exchange, and then the air is discharged from the bottom of the cabinet air conditioner and enters the room. This top-and-bottom air outlet mode can make the indoor temperature change more uniform. For example, in heating mode, hot air can be evenly distributed in the room by the upper air duct 25 and the lower air duct 25, avoiding the problems of traditional top air outlets, namely, cold air is denser than hot air, hot air is suspended at the top of the room and cold air sinks to the bottom of the room, causing children or users' feet to get cold, and hot air cannot quickly sink to the bottom of the room, resulting in a poor user experience.
