Referring to fig. 1, 2, 3, 4, 5 and 6, the vertical jet air conditioning unit of the present application includes an indoor unit; the indoor unit comprises a shell 1, a heat exchange assembly 2 and a fan assembly 3; the housing 1 includes a left side plate 11, a right side plate 12, and a front side plate 13; the space in the shell 1 is divided into a heat exchange cavity 16, a fan cavity 15 and a cavity of an air outlet cavity 14 which are separated from bottom to top in sequence. The heat exchange assembly 2 and the fan assembly 3 are respectively and fixedly arranged in the heat exchange cavity 16 and the fan cavity 15; the air outlet cavity 14 is communicated with the heat exchange cavity 16 through the fan assembly 3. At least one air outlet 131 communicating the indoor environment with the air outlet chamber 14 is formed at the upper portion of the front side plate 13; an air return port 132 is formed at the lower part of the front side plate 13, which communicates the indoor environment with the heat exchange chamber 16; the air quantity pumped by the fan assembly 3 from the return air inlet 132 to the heat exchange cavity 16 and discharged into the air outlet cavity 14 enters the indoor environment to be regulated from the air outlet 131, and the temperature of the indoor environment to be regulated is regulated.

The heat exchange component 2 is a water-cooling heat exchanger 23 or a refrigerant heat exchanger 23 and is arranged at the inner side of the return air inlet 132; the refrigerant heat exchanger 23 is a condenser or an evaporator in a refrigeration cycle formed 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 of a refrigerant, and refrigerating or heating an indoor space.

The low-temperature low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas into a high-temperature high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. Throughout the cycle, the heat exchange assembly 2 may regulate the temperature of the indoor space.

The heat exchange assembly 2 comprises a water outlet pipe 22, a water inlet pipe 21 and a heat exchanger 23; the power of the water circulation is a water pump. The medium water in the heat exchange assembly 2 exchanges heat with the indoor environment to adjust the indoor space temperature.

The vertical jet air conditioning unit further comprises an outdoor unit, which refers to a compressor and an evaporator or a condenser of the refrigeration cycle, or comprises the evaporator, the condenser, the compressor and a water heat exchange module of the refrigeration cycle. The expansion valve may be provided in the indoor unit or the outdoor unit.

Because the indoor unit of the vertical jet air conditioning unit is provided with the air outlet 131 at the upper part of the shell 1 and the air return 132 at the lower part of the shell 1, the air channel in the shell 1 is long, and because the air speed needs to be increased, the air outlet effect of the air outlet 131 forms jet, the air return 132 and the air outlet 131 are not at the same height and are positioned at the same side of the shell 1, the air direction is changed for a plurality of times, so that the noise problem of the indoor unit of the vertical jet air conditioning unit is more outstanding, and the use experience of a user is influenced. Of course, the return air inlet 132 and the air outlet 131 are not located at the same height and are located on two opposite sides of the casing 1, which also requires multiple wind direction changes, which causes significant noise problems.

The indoor unit further comprises at least one silencing and guiding assembly 4, which comprises a guiding piece and a silencing piece.

The two side edges of the guide piece in the width direction face the air outlet 131 and the fan cavity 15 respectively, so that the air quantity blown out by the fan cavity 15 is blown to the air outlet 131 through the guide of the guide piece. The two ends of the guide piece in the length direction are fixedly connected with the left side plate 11 and the right side plate 12 respectively. That is, both ends of the silencing and guiding assembly 4 in the longitudinal direction are fixedly connected with the left side plate 11 and the right side plate 12, respectively.

The silencing piece is a sheet structure which is made of silencing materials and is suitable for the size of a cavity, is arranged in the cavity and is used for reducing noise on the air quantity discharged into the air outlet cavity 14 by the fan assembly 3.

Specifically, the air volume discharged into the air outlet cavity 14 by the fan assembly 3 is blown to the silencing guide assembly 4, and is guided by the guide piece to be blown to the air outlet 131; in the process of guiding the air quantity by the guiding piece, noise carried by the air quantity enters the silencing piece through each first through hole 411 and each second through hole 421 and is absorbed by the silencing piece.

According to the vertical jet air conditioning unit, at least one silencing and guiding component 4 with two ends respectively facing the air outlet 131 and the fan cavity 15 is arranged in the air outlet cavity 14, so that the air quantity discharged by the fan component 3 is guided to be blown to the direction of the air outlet 131 and blown out, the air outlet direction is limited, and the air outlet quality and efficiency are improved; the amount of wind is along the in-process that the noise elimination water conservancy diversion subassembly 4 flows, and the noise that its carried is absorbed by the noise elimination spare in a plurality of first through-holes 411 and a plurality of second through-holes 421 entering cavity, noise level when reducing the operation promotes user's use and experiences.

In some specific embodiments, referring to fig. 1, 2, 3, 4, 5, and 6, the number of sound damping baffle assemblies 4 is a plurality.

The fan cavity 15 is separated from the air outlet cavity 14 by a partition plate 17; the partition 17 is transversely and fixedly arranged in the shell 1; the partition 17 is provided with a third through hole 171, which is used for communicating the fan cavity 15 with the air outlet cavity 14, and is used for installing the fan assembly 3, so that an air outlet of the fan assembly 3 is connected with the third through hole 171, the heat exchange cavity 16 is communicated with the air outlet cavity 14 through the fan assembly 3, and the fan cavity 15 is not communicated with the air outlet cavity 14.

Each silencing guide component 4 has different widths; the silencing and guiding components 4 are arranged in parallel from large to small along the directions from top to bottom and from back to front, and are fixedly connected with the left side plate 11 and the right side plate 12 respectively. Then, both ends of each silencing and guiding assembly 4 in the width direction face the air outlet 131 and the third through hole 171, respectively. That is, both ends of each silencing and guiding module 4 in the width direction face the air outlet 131 and the air outlet of the fan module 3.

In the vertical jet air conditioning unit of the embodiment, a plurality of silencing guide assemblies 4 are arranged in the air outlet cavity 14, so that the air quantity discharged by the air outlet of the fan assembly 3 is uniformly blown to the air outlet 131 through the guide of each silencing guide assembly 4, the air quantity of the air outlet 131 is uniform up and down, and the air outlet quality is improved; in addition, the arrangement of the plurality of silencing guide assemblies 4 increases the meeting area and the acting area of the air quantity and the silencing piece, improves the silencing effect and reduces noise.
