Description

Technical Field

[0001] The invention relates to the field related to air conditioner cleaning technology, and in particular to an air conditioner. Background Art

[0002] At present, with the continuous improvement of living standards, people pay more and more attention to air quality. As we all know, the parts of the air conditioner will become dirty during the use of time. As a result, when the air conditioner is turned on, the wind circulates through the air conditioner, which will bring out the unclean dust in the air conditioner. The existing technology evaporator parts already have self-cleaning technology that allows the evaporator to clean itself. However, the bottom shell water channel cannot be cleaned. Since the air conditioning condensed water is discharged to the outside of the air conditioner through the bottom shell water channel, the air conditioner has been running for a long time, and dust will accumulate in the water channel. The dust is easy to breed bacteria or block the water channel in the warm and humid environment of the water channel, resulting in poor drainage and leakage. Summary of the invention

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two, but does not exclude the inclusion of at least one.

[0040] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0041] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0042] At present, when the air conditioner is running, the condensed water of the air conditioner is discharged to the outside through the bottom shell water channel. When the air conditioner is running for a long time, dust will accumulate in the water channel. The dust is easy to breed bacteria in the warm and humid environment of the water channel or block the water channel, resulting in poor drainage and water leakage. Since the air conditioner drainage channel is inside the air conditioner, it is difficult for users to clean it. The present invention designs a mechanism for automatically cleaning the bottom shell water channel to solve this problem.

[0043] To further illustrate the technical solution of the present invention, Figure 1-Figure 5 As shown, the following specific embodiments are provided.

[0044] like Figure 1 , Figure 2 As shown, an air conditioner is provided in one embodiment of the present invention, the air conditioner comprising:

[0045] A housing 1 having a mounting cavity, and a water channel structure 3 is formed on the inner bottom of the housing 1, and the water channel structure 3 is used to receive condensed water generated on the evaporator assembly 4;

[0046] An evaporator assembly 4, which is arranged inside the installation cavity and above the water channel structure 3;

[0047] A cleaning component, which includes: an opening and closing mechanism, which is arranged at the drain outlet of the water channel structure 3 and is used to intercept or clear the condensed water accumulated in the water channel structure 3; and a cleaning wind wheel 2, which is arranged in the water channel structure 3 and is used to stir the condensed water in the water channel structure 3 to clean the inner bottom of the shell 1; and a driving mechanism, which is used to drive the cleaning wind wheel 2 to rotate and drive the opening and closing mechanism to open / close.

[0048] In this embodiment, a cleaning wind wheel 2 is added to the water channel structure 3, which is designed to be on the inner side of the water channel and installed in the middle of the water channel structure 3 of the bottom shell (the inner bottom of the shell). The diameter of the cleaning wind wheel 2 is smaller than the width of the air channel to avoid resonance caused by hitting the two sides of the water channel structure 3 of the bottom shell during operation. At the same time, it also avoids the cleaning wind wheel 2 from affecting the flow of air-conditioning condensed water in the bottom shell water channel when not in use, and does not affect the normal use of the air conditioner.

[0049] Preferably, the water channel structure 3 is arranged along the lower edge of the evaporator assembly 4. Accordingly, the cleaning wind wheel 2 is arranged along the direction of the water channel structure 3. Further, the cleaning wind wheel 2 includes: a plurality of ribs 12, which are arranged along the direction of the water channel structure 3 and are distributed around the same circle at intervals. The plurality of ribs 12 are all arc-shaped plates, and the plate surfaces of the arc-shaped plates are all bent in the same side direction of the circle.

[0050] Specifically: the cleaning wind wheel 2 in this embodiment is composed of dozens of arc-shaped ribs 12 staggered, and its function is to drive the water in the waterway to form a vortex through the arc-shaped ribs 12, so as to achieve a better cleaning effect. Figure 4-Figure 5 shown.

[0051] like Figure 3 As shown, preferably: the cleaning wind wheel 2 in this embodiment is installed on the inner side of the air duct through a motor, and the cleaning wind wheel 2 is driven to rotate by the rotation of the motor. The opening and closing mechanism drives the transmission gear 9 to rotate and control the opening and closing of the opening and closing baffle through the driving mechanism, so as to open and close the drain outlet.

[0052] like Figure 3 As shown, further, the driving mechanism includes: a first driving motor 6, which is fixed on the shell 1 and is used to drive the opening and closing mechanism to open / close through the transmission gear 9; and a second driving motor 5, which is fixed on the shell 1 and is used to drive the cleaning wind wheel 2 to rotate.

[0053] Preferably: in the present embodiment, a drain outlet is designed at one end of the bottom shell water channel structure 3 and an opening and closing mechanism is added, whose function is to receive the condensed water produced by the evaporator when closed, so that there is enough water in the water channel to provide the cleaning wind wheel 2 for rotation, and the opening and closing mechanism of the drain outlet is installed on the left side of the bottom shell, and the opening and closing of the drain outlet is realized by the rotation of the motor to achieve the effect of water storage and drainage.

[0054] like Figure 3As shown, further, the opening and closing mechanism includes: a stop plate. The stop plate includes: a plate body 8 and a rack 7. The plate body 8 is movably arranged at the drain outlet; the rack 7 is arranged on one side of the plate body 8, and is used to engage with the transmission gear 9 to drive the plate body 8 to perform an opening / closing action at the drain outlet through the first drive motor 6. A slot 11 is formed between the rack 7 and the plate body 8, and the slot is used to engage with the fixed plate on the housing 1 so that the plate body 8 can be movably arranged at the drain outlet. 10 is provided on one or both sides of the fixed plate that cooperate with the slot 11, and the guide structure 10 is used to guide the stop plate on its moving path when the opening and closing mechanism is driven to open / close. The second drive motor 5 is fixed to the cleaning wind wheel 2 in the middle of the bottom shell water channel by means of screws. Optionally: the guide structure is a guide bar or guide groove arranged on the housing along the movement direction of the stop plate; in contrast, a guide groove or guide bar is provided on the side of the rack 7 close to the fixed plate, and a guide groove or guide bar is provided on the side of the plate body close to the fixed plate.

[0055] When the drain outlet is located at one end of the waterway structure 3, the stop plate can be movably arranged at the drain outlet in the vertical direction. That is, the first drive motor 6 is used to drive the stop plate to move up and down. In addition, the movement direction of the stop plate can also be changed to horizontal, that is, the first drive motor 6 is used to drive the stop plate to move left and right through the rack 7 to open and close the drain outlet.

[0056] To further illustrate this embodiment, the self-cleaning process of the air conditioner in the embodiment will be described below.

[0057] The combination of the water channel structure 3 and the cleaning wind wheel 2 for cleaning the bottom shell is to use the evaporator of the air conditioner to produce condensed water during operation. An opening and closing mechanism is added to the drain port of the water channel structure 3 of the bottom shell to control it. When the air conditioner is running, evaporation produces condensed water. When the opening and closing mechanism is in a closed state, that is, the drain port is closed, the water channel structure 3 of the bottom shell will be full of condensed water, and the rotation of the cleaning wind wheel 2 drives the water to generate a vortex to clean the bottom shell water channel. The cleaning component for cleaning the bottom shell is divided into a water channel structure 3 and a driving mechanism. The driving mechanism is mainly divided into two parts, including a motor that provides kinetic energy and a cleaning wind wheel 2 for cleaning function. The diameter of the cleaning wind wheel 2 is smaller than the width of the air channel, which avoids the resonance caused by hitting the two sides of the bottom shell water channel during operation, and also avoids the cleaning wind wheel 2 from affecting the flow of the air conditioner condensed water in the bottom shell water channel when not in use, and does not affect the normal use of the air conditioner when not in use. The cleaning wind wheel 2 is composed of dozens of arc-shaped ribs 12 staggered, and its function is to better drive the water in the water channel to form a vortex through the arc-shaped ribs 12 when the cleaning air flow rotates, so as to better achieve the cleaning effect. The opening and closing mechanism at the drain outlet has a driving motor fixed to the bottom shell, connected to the transmission gear 9 to control the lifting of the opening and closing baffle, and the slot 11 (movement slot) formed between the plate body 8 and the rack 7 allows the stop plate to move up and down at the bottom shell. When the transmission gear 9 is rotated by the power provided by the motor, it drives the stop plate to move up and down, thereby controlling the opening and closing of the drain outlet. When the function is running, the opening and closing mechanism is in a closed state, the drain outlet of the bottom shell water channel structure 3 is closed, and the water channel structure of the bottom shell is filled with condensed water generated by the evaporator (the condensed water in the water channel structure reaches the preset water volume), and the cleaning wind wheel 2 rotates in the water through the power provided by the second driving motor 5, and the arc ribs 12 of the cleaning wind wheel 2 drive the water to generate a vortex to clean the bottom shell water channel. After cleaning, the opening and closing mechanism at the drain outlet is opened, that is, the stop plate is opened by the rotation of the transmission gear 9, and the drain outlet of the bottom shell is opened. The water after cleaning the water channel flows out of the air conditioner through the drain outlet to complete the cleaning process.

It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
