In the description of the present disclosure, the term "a plurality of' means two or more unless otherwise specified.
A ducted air conditioner in the present disclosure performs a refrigeration cycle of the ducted air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and a process of supplying refrigerant to air that has been conditioned and heat-exchanged.
The compressor compresses refrigerant gas in a state of high temperature and high pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to a surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant that is condensed in the condenser and is in the state of high temperature and high pressure into a liquid-phase refrigerant that is in a state of low pressure. The evaporator evaporates the refrigerant expanded in the expansion valve, and makes refrigerant gas in a state of low temperature and low pressure return to the compressor. The evaporator may achieve a refrigeration effect through heat exchange between latent heat of evaporation of the refrigerant and a material to be cooled. Throughout the cycle, the ducted air conditioner may regulate a temperature of an indoor space.
An outdoor unit of the ducted air conditioner refers to a part of the refrigeration cycle which includes the compressor and an outdoor heat exchanger. An indoor unit of the ducted air conditioner includes an indoor heat exchanger, and the expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger are used as the condensers or the evaporators. In a case where the indoor heat exchanger is used as the condenser, the ducted air conditioner is used as a heater in a heating mode. In a case where the indoor heat exchanger is used as the evaporator, the ducted air conditioner is used as a cooler in a refrigeration mode.
In an embodiment of the present disclosure, functional components of the ducted air conditioner include a fan system and a heat exchange system, which are arranged in separate spaces. The fan system makes air flow having a pressure enter a space where the heat exchange system is located, and after being heat exchanged by the heat exchange system, the air flow enters the air duct. Then, the air flow having the pressure enters each room through the air duct for refrigeration or heating.
Referring to FIGS. 1 and 2, the ducted air conditioner of the present disclosure includes a housing 1, a heat-retaining and drainage device 2, a heat exchange system 3 and a fan system 4.
The housing 1 includes a box body with an opening facing downward and a lower cover plate 15. The lower cover plate 15 matches the opening of the box body, and is connected with the opening of the box body.
The box body includes a first side plate 12, a second side plate 13, a base plate 11 and a front panel 14. The second side plate 13 and the first side plate 12 constitute a left side wall and a right side wall of the housing 1 respectively. The base plate 11 constitutes an upper wall of the housing 1. The front panel 14 constitutes a front wall of the housing 1.
Referring to FIGS. 2, 3 and 4, the heat-retaining and drainage device 2 includes an upper heat-retaining member 21 and a drain pan 22. The upper heat-retaining member 21 is used for heat isolation of the housing 1. The drain pan 22 is used for receiving condensed water when the ducted air conditioner is used for refrigeration, and may also have a function of heat isolation.
The upper heat-retaining member 21 is connected with the drain pan 22 to separate a cavity of the housing 1, so that the housing includes a first cavity and a second cavity that are separate. The heat exchange system 3 is fixedly installed in the first cavity, and is between the upper heat-retaining member 21 and the drain pan 22. The fan system 4 is fixedly installed in the second cavity.
The heat-retaining and drainage device 2 has functions of retaining heat, receiving condensed water, and isolating the fan system 3 and the heat exchange system 4, which saves a partition plate in traditional components, reduces the components of the ducted air conditioner and saves the cost. Moreover, the number of screws used for connection is reduced, which improves the assembly efficiency.
Referring to FIGS. 1, 2 and 4, the ducted air conditioner further includes an electrical control box 5, which is fixedly installed at an end of the first cavity and includes a metal electric box 51. The metal electric box 51 is connected with the first side plate 12, so as to jointly form a side wall at an end portion of the housing 1. The metal electric box 51 is connected with the lower cover plate 15, so as to jointly form a lower wall of the housing 1.
Referring to FIGS. 2 and 4, the metal electric box 51 includes a front side plate 511. A distance between the front side plate 511 and the front panel 14 matches a dimension of the heat-retaining and drainage device 2. That is, the heat-retaining and drainage device 2 is installed in the cavity of the housing 1, is located between the metal electric box 51 and the front panel 14, and is connected with the front side plate 511.
The metal electrical control box 51 and the front panel 14 play a role of positioning and restricting the heat-retaining and drainage device 2 during installation. As a result, the heat-retaining and drainage device 2 may be fixedly installed without using screws. Thus, the number of screws used for connection is reduced.
In some embodiments of the present disclosure, a notch whose dimension is less than that of the front side plate 511 is provided at a portion where the heat-retaining and drainage device 2 is connected with the metal electric box 51, so as to save materials and reduce the material cost.
Referring to FIGS. 2 and 3, the upper heat-retaining member 21 includes a first inner side plate 211 and a first base plate 212. The first inner side plate 211 is vertically connected with a side of the first base plate 212.
The drain pan 22 includes a second inner plate 221 and a second base plate 222. The second inner plate 221 is vertically connected with a side of the second base plate 222. The first inner side plate 211 is connected with the second inner side plate 221, which divides the cavity of the housing 1 into the separate first cavity and second cavity.
In some embodiments of the present disclosure, a lower end of the first inner side plate 211 is connected with an upper end of the second inner side plate 221 in an abutting manner, rather than being fixedly connected with each other through screws, which reduces the number of screws used, reduces the labor consumption and a weight of the ducted air conditioner, and reduces the cost and facilitates a transportation of the ducted air conditioner.
For structures and a connection method of the first inner side plate 211 and the second inner side plate 221, descriptions will be made in detail below.
Referring to FIGS. 2 and 5, the heat exchange system 3 is installed in the first cavity through a connection between a slideway 311 and a slide rail 321.

Finally, the heat exchanger 34 and the box body are fixedly connected together through a fixed connection between the second fixing member 33 of the heat exchanger and the front panel 14, and a fixed connection between the slideway 311 and the slide rail 321. The piping 35 and the piping mounting hole 124 also have a function of positioning, which simplifies a design structure and facilitates the installation, reduces the cost and improves the installation efficiency.
Referring to FIGS. 2, 3 and 4, the box body further includes a fan installation device, which includes a motor mounting frame 18. The motor mounting frame 18 is fixedly connected with the base plate 11.
The fan system 4 includes a motor 41 and a volute 42. The motor 41 is fixedly installed on the motor mounting frame 18. The volute 42 is fixedly connected with the box body in a clamping manner.
In some embodiments of the present disclosure, the box body further includes a mounting plate 17, which is fixedly connected with the base plate 11 and includes a groove. The groove includes a groove opening and a groove bottom. The groove opening faces the base plate. A plurality of bayonets 171 are provided on the groove bottom.
In some embodiments of the present disclosure, the mounting plate 17 and the base plate 11 are fixedly connected in a riveting manner, so that a connection operation of the mounting plate 17 and the base plate 11 may be centralized in batches, thereby improving an operation efficiency.
A fastener connected with and matching each bayonet 171 is provided at a position corresponding to each bayonet 171 on the volute 42. Each fastener matches a corresponding bayonet 171, so that the volute 42 is fixedly connected with the mounting plate 17, and thus connected with the base plate 11.
Correspondingly, the motor mounting frame 18 is fixedly connected with the mounting plate 17 and the base plate 11. Description will be made in detail below.
Of course, the volute 42 may be directly connected with the base plate 11 in the clamping manner. That is, the bayonets are provided on the base plate 11. Each fastener is connected with a corresponding bayonet in the clamping manner. By providing the mounting plate 17, an appearance of the ducted air conditioner is more aesthetically pleasing.

A connection of the buckle 312 and the clamping groove 322 limits the position of the heat exchanger 34 in an up direction and a down direction on the basis of the above. In this way, the assembly efficiency is improved.
The second fixing member 33 of the heat exchanger is fixedly connected with the box body. Preferably, the heat exchanger 34 is a V-shaped heat exchanger, and the second fixing member 33 of the heat exchanger is fixedly connected with the front panel 14 through screws.
The assembly method is as follows. An end of the heat exchanger 34 on which the second fixing member 33 of the heat exchanger is fixed is placed on an end of the box body 1 and is connected with the front panel 14, so that the piping 35 is located in the piping mounting hole 124. Then, the slide rail 321 of the first fixing member 32 of the heat exchanger slides into the slideway 311. In a case where the slide rail 321 slides into a bottom end of the slideway 311, the buckle 312 is clamped with the clamping groove 322.
The connection between the slide rail 311 and the slideway 321 enables the installation and positioning of the heat exchanger 34 to be accurate and quickly fixed, thereby improving the assembly efficiency. The connection may also be assisted through screws, which may improve the installation quality and reliability.
In some embodiments of the present disclosure, the fixing member 31 at the end portion of the housing, the first fixing member 32 of the heat exchanger, and the second fixing member 33 of the heat exchanger are all made of plastic rubber or plastic materials, so that only a small amount of heat on the heat exchanger 34 is transferred to the housing, thereby reducing the heat loss. During refrigeration, generation of condensed water on the housing is reduced, thereby improving the user experience.
