Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, in particular to an air conditioner. BACKGROUND

[0002] Generally, the cooling of the electric control radiator of the conventional double air pipe mobile air conditioner can only rely on the heat exchange effect generated by the outdoor hot air, the cooling effect is limited, the cooling speed is slow, the electric control components are in high temperature state for a long time, the working stability and the service life are reduced, and the working stability and the service life of the whole machine are affected. INNOVATION CONTENT

[0003] Therefore, it is necessary to provide an air conditioner in view of the poor heat dissipation effect of the electric control radiator of the existing part of the mobile air conditioner, the electric control components are in high temperature state for a long time, the working stability and the service life are reduced, and the working stability and the service life of the whole machine are affected.

[0004] An air conditioner comprises a cabinet, a first air inlet, a second air inlet and a heat dissipation air outlet, a refrigeration system, a control mechanism and a heat dissipation assembly.

[0005] This application provides an air conditioner with a fan assembly installed within the casing cavity. The fan assembly drives air from a first and second air inlet through a heat dissipation duct towards the heat dissipation outlet. During air flow, the air exchanges heat with the condenser to improve the cooling efficiency of the refrigeration system. A heat dissipation component is located within the heat dissipation duct, allowing some air to carry away heat absorbed by the heat dissipation component from the control mechanism, thereby reducing the operating temperature of the electronic control components and improving the air conditioner's efficiency. Specifically, the first air inlet connects to the outside, and the second air inlet connects to the inside. On one hand, the second air inlet works in conjunction with the first air inlet to increase the heat exchange airflow to the condenser, improving the heat exchange efficiency of the refrigeration system. On the other hand, the heat dissipation duct draws in already cooled indoor air, lowering the temperature of the airflow passing through the heat dissipation component and accelerating the cooling speed of the heat dissipation component and control mechanism.

[0006] In one embodiment, the fan assembly includes a negative pressure fan and a duct housing. The duct housing is disposed within the mounting cavity and has an air guide cavity. The air inlet of the air guide cavity is opposite to the condenser, and the air outlet of the air guide cavity is connected to the heat dissipation vent. The negative pressure fan is disposed within the air guide cavity. By adopting this structure, the condenser and the heat dissipation vent are connected through the air guide cavity. When the negative pressure fan starts, a negative pressure environment is formed at the air outlet side of the air guide cavity, which helps to increase the air velocity at the first and second air inlets. This allows the air conditioner to use a lower-power negative pressure fan while achieving the same efficiency, thereby reducing energy consumption and costs, while also reducing operating noise and improving the user experience.

[0007] In one embodiment, the condenser divides the mounting cavity into a first cavity and a second cavity. The heat dissipation assembly is disposed in the first cavity, and the air duct housing is disposed in the second cavity. The first air inlet and the second air inlet are respectively connected to the first cavity. The first cavity, the condenser, the air guide cavity, and the heat dissipation vent are sequentially connected to form the heat dissipation air duct. By adopting the above structure, using the condenser to divide the mounting cavity into a first cavity and a second cavity, it is convenient to rationally arrange the refrigeration system, heat dissipation assembly, and fan assembly, which is beneficial for the heat entering the heat dissipation air duct to better flow through the refrigeration system and heat dissipation assembly to remove heat.

[0008] In one embodiment, the heat dissipation component is located in the first cavity.

[0009] In one embodiment, at least one of the compressor, the evaporator, and the throttling device is disposed in the first cavity.

[0010] In one embodiment, the duct housing includes a duct body and a mounting platform. The duct body is disposed opposite to the condenser and has the air guide cavity. The mounting platform is disposed on the duct body and located above the condenser. The control mechanism is disposed on the side of the mounting platform away from the condenser. By adopting the above structure, the mounting platform facilitates the installation and fixation of the control mechanism and allows for the adjacent placement of the heat dissipation components and the condenser.

[0011] In one embodiment, the mounting platform abuts against the control mechanism and the condenser on both sides, respectively. Specifically, the mounting platform is made of metal. By adopting the above structure and connecting the mounting platform to the control mechanism and the condenser respectively, the gas flowing through the condenser can generate a certain heat exchange effect between the control mechanism and the condenser, thereby reducing the operating temperature of the control mechanism.

[0012] In one embodiment, one of the control mechanism and the mounting platform has a locking block, and the other of the control mechanism and the mounting platform has a locking slot, with the locking block engaging in the locking slot. By providing compatible locking blocks and slots on the control mechanism and the mounting platform respectively, the cooperation between the locking blocks and the slots can limit the installation of the control mechanism, thereby facilitating the rapid positioning and assembly of the control mechanism.

[0013] In one embodiment, the heat dissipation component is located on the side of the condenser away from the air duct body and is disposed adjacent to the condenser.

[0014] In one embodiment, one of the condenser and the duct housing has a mounting port, and the other of the condenser and the duct housing is fitted with the mounting port. The condenser is connected to the air inlet of the air guide cavity through the mounting port. By adopting the above structure, the airtightness at the connection between the condenser and the duct housing can be effectively improved, thereby allowing the airflow generated by the negative pressure fan to fully flow through the condenser and exchange heat with it.

[0015] In one embodiment, the duct housing is a volute duct, and the airflow direction at the air inlet of the air guide cavity forms an angle with the airflow direction at the air outlet of the air guide cavity. By using a volute duct, it is convenient to arrange the first air inlet and / or the second air inlet and the heat dissipation vent on the same side, so that the pipes connecting the first air inlet or the second air inlet and the heat dissipation vent to the outside can be centrally arranged, thereby improving the aesthetics of the air conditioner.

[0016] In one embodiment, the control mechanism includes a mounting housing and control elements. The mounting housing is disposed on the chassis and has a mounting wall. The control elements and heat dissipation components are respectively disposed on opposite sides of the mounting wall. The mounting wall is made of metal, and the control elements and heat dissipation components are respectively disposed on opposite sides of the mounting wall, so that the heat generated by the control elements can be quickly transferred to the heat dissipation components through the mounting wall to improve the cooling rate.

[0017] In one embodiment, the heat dissipation component is disposed opposite to the first air inlet and / or the second air inlet and distributed along the air intake direction of the first air inlet and / or the second air inlet. This allows the airflow entering the heat dissipation duct to make more full contact with the heat dissipation component and remove heat more quickly.

[0018] In one embodiment, the heat dissipation component is a finned heat sink. It is made of a metal material, such as aluminum alloy, and the fins can be flat, corrugated, or concave-convex, etc. Its main function is to increase the surface area of ​​the heat sink and improve heat dissipation.

[0019] In one embodiment, a roller assembly is also included, which is movably disposed at the bottom of the chassis. The roller assembly allows the user to easily move the air conditioner as needed.

[0020] In one embodiment, the heat dissipation vent is connected to the outside via a duct. Attached Figure Description

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0034] The air conditioner according to some embodiments of the present invention is described below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, this embodiment discloses an air conditioner, including: a casing 1, the casing 1 having a mounting cavity 101 and a first air inlet 102, a second air inlet 103, and a heat dissipation vent 104 respectively connected to the mounting cavity 101; the first air inlet 102 being connected to the outside via a pipe, and the second air inlet 103 being connected to the inside; and a refrigeration system 2, at least a portion of which is disposed in the mounting cavity 101. The refrigeration system 2 includes a compressor, a condenser 21, a throttling device, and an evaporator connected end-to-end to form a refrigerant circuit. 04 are connected in sequence to form a heat dissipation duct; control mechanism 3 is installed on the chassis 1 and is electrically connected to the refrigeration system 2; heat dissipation component 4 is located in the heat dissipation duct and is connected to the outer wall of the control mechanism 3 to absorb the heat generated by the control mechanism 3; fan assembly 5 is located at least partly in the mounting cavity 101 and is used to drive outside air to flow through the first air inlet 102 and the second air inlet 103 into the heat dissipation duct and be discharged outward through the heat dissipation outlet 104 to carry away the heat absorbed by the heat dissipation component 4.

[0036] This application provides an air conditioner. A fan assembly 5 is installed within the mounting cavity 101 of the casing 1. The fan assembly 5 drives the gas from the first air inlet 102 and the second air inlet 103 to flow through the heat dissipation duct to the heat dissipation outlet 104. During this gas flow, heat is exchanged with the condenser 21 to improve the cooling efficiency of the refrigeration system 2. The heat dissipation component 4 is located within the heat dissipation duct, thus carrying away some of the heat absorbed by the heat dissipation component 4 from the control mechanism 3, thereby reducing the operating temperature of the electronic control components and improving the air conditioner's efficiency. Specifically, the first air inlet 102 connects to the outside, and the second air inlet 103 connects to the inside. On one hand, the second air inlet 103 works in conjunction with the first air inlet 102 to increase the heat exchange airflow of the condenser 21, which is beneficial for improving the heat exchange efficiency of the refrigeration system 2. On the other hand, the heat dissipation duct draws in already cooled indoor air, which lowers the temperature of the airflow passing through the heat dissipation component 4, thereby accelerating the cooling speed of the heat dissipation component 4 and the control mechanism 3.

[0037] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 5 includes a negative pressure fan 51 and a duct housing 52. The duct housing 52 is disposed in the mounting cavity 101 and has a guide cavity 501. The air inlet of the guide cavity 501 is opposite to the condenser 21, and the air outlet of the guide cavity 501 is connected to the heat dissipation vent 104. The negative pressure fan 51 is disposed in the guide cavity 501. By adopting the above structure, the condenser 21 and the heat dissipation vent 104 are connected through the guide cavity 501. When the negative pressure fan 51 is started, a negative pressure environment is formed on the air outlet side of the guide cavity 501, which is beneficial to increasing the wind speed of the first air inlet 102 and the second air inlet 103. This allows the air conditioner to choose to use a lower power negative pressure fan 51 while achieving the same efficiency, thereby reducing energy consumption and cost, and also reducing operating noise, thereby improving the user experience.

[0038] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the condenser 21 divides the mounting cavity 101 to form a first cavity 1011 and a second cavity 1012; the heat dissipation assembly 4 is disposed in the first cavity 1011; the air duct housing 52 is disposed in the second cavity 1012; the first air inlet 102 and the second air inlet 103 are respectively connected to the first cavity 1011; and the first cavity 1011, the condenser 21, the air guide cavity 501, and the heat dissipation vent 104 are sequentially connected to form a heat dissipation air duct. By adopting the above structure, the mounting cavity 101 is divided by the condenser 21 to form the first cavity 1011 and the second cavity 1012, which facilitates the reasonable arrangement of the refrigeration system 2, the heat dissipation assembly 4, and the fan assembly 5, and helps the heat entering the heat dissipation air duct to flow better through the refrigeration system 2 and the heat dissipation assembly 4 to remove heat.

The control mechanism 3 is disposed on the side of the mounting platform 522 away from the condenser 21.
