An air guide grille is provided, the air guide grille includes a plurality of grid strips, wherein the plurality of grid strips are arranged in a plurality of rows, an air inlet side edge of each of the plurality of grid strips is of a corrugated shape, and an air inlet side edges of two adjacent rows of grid strips in the plurality of grid strips is provided in a staggered manner along a length direction of the corrugation. In order to form a corrugated air inlet between two adjacent rows of gate strips, the each of the plurality of grid strips has an air guide surface inclined toward a first direction along the air guiding direction thereof, and the first direction is parallel to an undulating direction of a corrugation. In addition, an air inlet panel and an air conditioner are also disclosed.

An air conditioner is provided that may include a case in which a heat exchanger is disposed and having an air inlet and an air outlet; a discharge pipe that communicates with the air outlet and extends outside of the case; and a kit having a discharge port in which the discharge pipe is fixed, and configured to be disposed at a window frame. The kit may include a main board in which the discharge port is formed; at least one sub-board configured to be movable up and down with respect to the main board; a rack connected with one of the main board or the at least one sub-board and forming a plurality of grooves spaced apart from each other in an upward-downward direction; and a holder connected with the other one of the main board or the at least one sub-board and having a protrusion inserted into one of the plurality of grooves to restrict upward-downward movement of the at least one sub-board.

A ductless HVAC containment system is provided, wherein the system is intended to conceal traditional wall hung ductless HVAC components, such as mini split system air handlers. The system may be installed in new construction, retrofits, and during renovations of homes, offices, schools, etc. The system provides an ascetic and functional solution to the growing demand of ductless HVAC units. The system features a cabinet and cover combination engineered to be installed directly into the framing of a wall. The cabinet provides a recess for the air handler and other components that are not in the air handler's housing. The removable cover conceals the cabinet and provides a means to access the components. Vents and baffles positioned on the removable cover enable control of airflow.

An air diffuser and air diffusing system is herein disclosed. The air diffuser generally includes a base and a diffuser plate. The base is designed to attach to a surface proximal an air duct and further defines an air-in opening through which air is configured to flow in a first direction. The diffuser plate detachably couples to the base. The diffuser plate and base define a laterally disposed air-out opening that is designed to direct the air in a second direction that is substantially perpendicular to the first direction.

The present disclosure provides a rotary dancing aromatherapy humidifier, which includes a main machine body of the humidifier, a control circuit board arranged inside the main machine body of the humidifier, an atomizing plate sub-assembly and a rotary driving mechanism. The main machine body of the humidifier includes a water tank body, a rotating pattern ring with a grid pattern is located on the outside of the water tank body, a grid tube on the outside of the rotating pattern ring, and also includes a rotating seat for installing the rotating pattern ring; the rotating driving mechanism drives the rotating seat and the rotating pattern ring to rotate axially, and the atomizing plate sub-assembly and the rotating driving mechanism are electrically connected with the control circuit board.

A middle air duct support member and an air conditioner provided. The middle air duct support member has an annular first support portion and an annular second support portion arranged at an axial end of the first support portion. The second support portion and the first support portion are manufactured separately.

A room air purifier has a body with a frame at least partially defining an interior chamber and an opening to the chamber. A purification mechanism in the chamber includes one or more filters and one or more blowers. A panel is configured to removably mount to the body and cover the opening to the chamber. A base mounted to the body, and each leg of a set of legs is mounted to the base. A nonwoven fabric portion covers at least part of the body. The blower when activated generates an inflow through the nonwoven fabric portion and a filter, and an outflow though the body, all while hidden from view in what to an observer looks like an article of furniture.

An outdoor misting assembly for producing a cooling mist during hot day includes a housing that has a fluid reservoir therein that can be filled with water. A misting unit is positioned in the fluid reservoir and the misting unit can be submerged in the water. The misting unit vibrates at a pre-determined frequency when the misting unit is turned on to vibrate the water into a mist. A plurality of tubes is each fluidly coupled to the misting unit to receive the mist. Each of the tubes extends outwardly from the housing to direct the mist toward a plurality of users for cooling the users during a hot day.

An air conditioner includes a housing. The housing includes a panel including an opening. The air conditioner further includes an indicator light arranged at the opening, an air heat exchange duct and an air treatment duct arranged in the housing and not in communication with each other, an air heat exchange device arranged at the air heat exchange duct and configured to conduct heat exchange for air in the air heat exchange duct, and an air treatment device arranged at the air treatment duct and configured to conduct at least one of humidification or purification for air in the air treatment duct.

The present disclosure provides a ventilation and air conditioning system. The ventilation and air conditioning system can include a ventilation and air conditioning body including a ventilation component and an automatic air-output device arranged at a ventilation outlet of the ventilation and air conditioning body and configured to open or close the ventilation outlet according to an operating state of the ventilation component. The automatic air-output device is coupled to a power switch of the ventilation component. When the ventilation component is powered on, the automatic air-output device opens the ventilation outlet of the ventilation component to allow fresh air of the ventilation component to flow indoors. When the ventilation component is powered off, the automatic air-output device closes the ventilation outlet.
