Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly provides an indoor air conditioner. Background Art

[0002] Traditional household air conditioners include an indoor unit and an outdoor unit. When the air conditioner is working, it can usually only guide the indoor air circulation and cannot introduce fresh outdoor air. After running for a period of time, the indoor air quality will decline. To solve the above problems, a fresh air module is generally set in the existing indoor air conditioner to improve the air quality of the indoor environment, refresh the indoor air, and effectively improve the customer experience.

[0003] In the existing floor-standing air conditioner indoor unit, the air outlet of the air conditioner is usually designed at the upper part, and the fresh air module is set at the lower part. To save the internal space of the floor-standing air conditioner indoor unit and make the internal structure more compact, the electrical box of the floor-standing air conditioner indoor unit is usually installed on the fresh air module, such as directly below the air outlet frame. When the cold air is output from the air outlet of the air conditioner, the cold air will reduce the temperature of the air outlet frame. When the warm and humid indoor air contacts the relatively low-temperature air outlet frame, the water vapor in the air will condense into water droplets and adhere to the inner side surface of the air outlet frame, thus forming a small amount of condensed water on the inner side surface of the air outlet frame. The condensed water will drip downward under the action of gravity, so there is a risk that the condensed water will fall into the electrical box directly below, which is likely to cause a short circuit of the electronic components in the electrical box and make the air conditioner malfunction or be damaged.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a cabinet-type air conditioner indoor unit. The cabinet-type air conditioner indoor unit includes a front panel frame 1, a rear panel frame 2, a base 3, an electrical box 4, a fresh air module 5, etc. Specifically, the front panel frame 1 and the rear panel frame 2 are sequentially arranged on the base 3 from front to back along the front-rear direction of the cabinet-type air conditioner indoor unit. After the front panel frame 1 and the rear panel frame 2 are enclosed, the internal space of the cabinet-type air conditioner indoor unit is constructed, and the electrical box 4, the fresh air module 5, etc. are all arranged in the internal space of the cabinet-type air conditioner indoor unit.

[0035] As Figure 2 and Figure 3As shown in the figure, an air outlet frame structure 11 and a water receiving tray 12 are provided on the front panel frame 1. The water receiving tray 12 is located below the air outlet frame structure 11, and the electrical box 4 is located below the water receiving tray 12. The fresh air module 5 includes a fresh air inlet component 52, a fan component 53, and a fresh air outlet component 51. The fresh air inlet component 52 and the fan component 53 are arranged on the base 3. A fan device is arranged in the fan component 53. The fresh air outlet component 51 includes a fresh air outlet pipe 511, and the fresh air outlet pipe 511 is arranged on the fan component 53. The inlet of the fresh air inlet component 52 is communicated with the outside, the outlet of the fresh air inlet component 52 is communicated with the inlet of the fan component 53, and the outlet of the fan component 53 is communicated with the inlet of the fresh air outlet pipe 511, thereby forming a path for fresh air to flow. Outdoor fresh air can enter the fresh air inlet component 52 driven by the fan device and finally enter the room from the fresh air outlet pipe 511.

[0036] As Figure 4 shown in the figure, a water collecting part 111 is constructed at the bottom of the air outlet frame structure 11. The condensed water in the air outlet frame structure 11 can gather downward under the action of gravity in the water collecting part 111 at its bottom. A second water outlet 1111 is arranged at the bottom of the water collecting part 111. The second water outlet 1111 is correspondingly arranged with the water receiving tray 12, so that the condensed water received by the water collecting part 111 can drip into the water receiving tray 12 through the second water outlet 1111. A first water outlet 121 is arranged at the bottom of the water receiving tray 12. An outward extending rib 5113 is arranged on the outer surface of the fresh air outlet pipe 511. The rib 5113 encloses to form a water guiding structure. The water guiding structure is correspondingly arranged with the first water outlet 121 of the water receiving tray 12. The water guiding structure has a water collecting function. The condensed water received by the water receiving tray 12 can drip into the water guiding structure through the first water outlet 121. The water guiding structure is arranged to guide the condensed water received by it to drip downward from a position avoiding the electrical box 4, that is, directly drip on the base 3. It should be noted that during the refrigeration process of the cabinet-type air conditioner indoor unit, a small amount of condensed water will be formed on the inner side surface of the air outlet frame structure 11. This small amount of condensed water finally dripping on the base 3 will not affect the normal operation of the cabinet-type air conditioner indoor unit, and the small amount of condensed water dripping on the base 3 will naturally evaporate after a period of time and will not remain on the base 3 all the time.

[0037] The cabinet-type air conditioner indoor unit provided by the embodiment of the present invention, by arranging the water receiving tray 12 below the air outlet frame structure 11, enables the water receiving tray 12 to receive the condensed water in the air outlet frame structure 11. At the same time, by arranging a water guiding structure on the fresh air outlet pipe 511, after the condensed water in the water receiving tray 12 drips into the water guiding structure, the water guiding structure can guide the condensed water inside it to drip downward from a position avoiding the electrical box 4, thereby avoiding the condensed water from dripping on the electrical box 4, and further reducing the probability of the electronic components in the electrical box 4 touching water and causing air conditioner failures or damages.

[0038] Further, continue to refer to Figure 4 , the water guiding structure extends from the top surface of the fresh air outlet duct 511 to the side surface of the fresh air outlet duct 511. Through the above arrangement, the water guiding structure can guide the condensed water it bears to flow along a predetermined path from the top surface to the side surface of the fresh air outlet duct 511, avoiding the accumulation of condensed water on the top surface of the fresh air outlet duct 511, thereby preventing waterlogging on the top surface of the fresh air outlet duct 511.

[0039] Further, continue to refer to Figure 4 , the area surrounded by the part of the water guiding structure located on the side surface of the fresh air outlet duct 511 gradually narrows from top to bottom. Through the above arrangement, the rib 5113 of the part of the water guiding structure located on the side surface of the fresh air outlet duct 511 has a certain inclination angle, which is beneficial to the flow of condensed water along the preset path, reducing the time for condensed water to stay on the side surface of the fresh air outlet duct 511, and further preventing waterlogging on the side surface of the fresh air outlet duct 511.

[0040] As Figure 5 shown, the fresh air inlet assembly 52 includes a fresh air inlet housing 521, the fan assembly 53 includes a fan housing 531, the fan device is arranged in the fan housing 531, the fresh air inlet housing 521 and the fan housing 531 are arranged in sequence from back to front along the front-back direction of the cabinet-type air conditioner indoor unit, and the air outlet end of the fresh air inlet housing 521 is connected to the air inlet end of the fan housing 531. The fresh air outlet duct 511 includes a first fresh air outlet duct 5111 and a second fresh air outlet duct 5112. The opening of the air outlet end of the first fresh air outlet duct 5111 faces backward, the air inlet end of the first fresh air outlet duct 5111 is bent downward and connected to the air outlet end of the fan housing 531, the opening of the air outlet end of the second fresh air outlet duct 5112 faces forward, the second fresh air outlet duct 5112 is a branch duct formed on the first fresh air outlet duct 5111, and the rib 5113 is arranged on the second fresh air outlet duct 5112.

[0041] Further, continue to refer to Figure 5 , the electrical box 4 is arranged on the fan housing 531 through fasteners, and the water guiding structure is arranged to be able to guide the condensed water it receives to drip downward from the rear position of the electrical box 4, thereby preventing the condensed water from dripping on the electrical box 4, and further reducing the probability of the electronic components in the electrical box 4 being touched by water, resulting in air conditioner failure or damage.

[0042] In some specific embodiments, the electrical box 4 is arranged on the fresh air inlet housing 521 through fasteners, and the water guiding structure is arranged to be able to guide the condensed water it receives to drip downward from the front position of the electrical box 4, thereby preventing the condensed water from dripping on the electrical box 4, and further reducing the probability of the electronic components in the electrical box 4 being touched by water, resulting in air conditioner failure or damage.

[0043] AsFigure 6 and Figure 7 As shown in Figure 7 , the fresh air outlet duct 511 includes a first fresh air duct housing 511a and a second fresh air duct housing 511b that are snap-connected to each other to form an integral structure. The rib 5113 is only provided on the outer surface of the first fresh air duct housing 511a or the outer surface of the second fresh air duct housing 511b. In this embodiment, the rib 5113 is only provided on the outer surface of the first fresh air duct housing 511a and encloses a water guiding structure that extends from the top surface of the first fresh air duct housing 511a to the outer side surface of the first fresh air duct housing 511a. It should be noted that since the fresh air outlet duct 511 is formed by snap-connecting the first fresh air duct housing 511a and the second fresh air duct housing 511b, there is a joint line between the first fresh air duct housing 511a and the second fresh air duct housing 511b. In order to prevent condensed water from flowing into the fresh air outlet duct 511 through the gap of the joint line, in the embodiment of the present invention, by only providing the rib 5113 on the outer surface of the first fresh air duct housing 511a or the outer surface of the second fresh air duct housing 511b, the joint line is not within the enclosed area of the water guiding structure formed by enclosing the rib 5113, thereby preventing condensed water from flowing into the fresh air outlet duct 511 between the first fresh air duct housing 511a and the second fresh air duct housing 511b.

[0044] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
