Abstract: CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a National Phase Application under 35 U.S.C. § 371 of International Application No. PCT/KR2020/017380, filed on Dec. 1, 2020, which claims priority to Korean Application No. 10-2019-0159187, filed on Dec. 3, 2019. The disclosures of the prior applications are incorporated by reference in their entirety.
A vacuum cleaner includes a main body and a suction nozzle. The suction nozzle includes a housing and a rotating brush. The rotating brush includes a first rotating brush, a second rotating brush, and a coupler. The coupler couples the first rotating brush and the second rotating brush so that a rotation axis of the first rotating brush and a rotation axis of the second rotating brush are positioned on the same line.-

Abstract: A vacuum cleaner includes a main body and a suction nozzle. The suction nozzle includes a connector that defines a passage configured to guide the dust in a first direction to the main body, and a housing that rotatably connects to the connector and defines an inlet configured to transfer the dust to the passage. The connector includes an insertion portion that has a cylindrical shape and is configured to insert into the inlet, a first connection portion spaced apart from the inlet in the first direction, and a coupling part disposed at an outer surface of the insertion portion. The coupling part and the first connection portion are configured to restrict movement of the housing in the first direction, and the inlet is configured to restrict deformation of at least one of the insertion portion or the coupling part.

Abstract: The present invention relates to an air conditioner capable of performing heat exchange of refrigerant and cooling and heating operations. According to the invention, a dual-tube heat exchanger is disposed at the entrance of a compressor and a means for switching a cooling cycle is installed between an outdoor heat exchanger including a condenser and an indoor heat exchanger including an evaporator so that in an air conditioning mode, heat change between mid-temperature, high-pressure liquid refrigerant at the exit of the condenser and low-temperature, low-pressure superheated refrigerant at the exit of the evaporator is performed more effectively and as a result of this, super heating of the liquid refrigerant at the exit of the condenser is increased, refrigerant flow characteristics of an expansion unit are improved, and enthalpy at the entrance side of the evaporator is reduced, causing a greater enthalpy difference at the entrance and exit of the evaporator and improving air conditioning capacity overall. Moreover, the heat exchanger of the present invention has a dual tube structure and uses a counter flow or parallel flow for performing heat exchange. In the dual tube structure, a tube and a core of the heat exchanger form a line or surface contact and heating capacity is therefore enhanced.
Abstract translation: 本发明涉及能够进行制冷剂的热交换和制冷加热运转的空调机。 根据本发明，在压缩机的入口处设置双管热交换器，并且在包括冷凝器的室外热交换器和包括蒸发器的室内热交换器之间设置用于切换冷却循环的装置，使得在空气中 在冷凝器出口处的中温，高压液体制冷剂和蒸发器出口处的低温，低压过热制冷剂之间的热变化更有效地进行，因此，超加热 在冷凝器出口处的液体制冷剂增加，膨胀单元的制冷剂流动特性得到改善，并且蒸发器入口侧的焓减小，从而在蒸发器的入口和出口处产生较大的焓差，并且改善了 整体空调能力。 此外，本发明的热交换器具有双管结构，并且使用逆流或并联流来进行热交换。 在双管结构中，热交换器的管和芯形成线或表面接触，因此加热能力增强。
