An electrical control panel for connector terminals, an electrical control cabinet, and an air conditioner, including: a motherboard body; a connector terminal body, the connector terminal body disposed on the motherboard body, at least one connector terminal body, a plurality of connection ports and control switches corresponding to the connection ports disposed on the connector terminal body, the connection ports connected to the components of the motherboard body through conducting wires, and the control switches act to compress or loosen the conducting wires. A connector terminal body is disposed on the motherboard body and the control switch can compress or loosen the conducting wire inserted into the connection port, reducing the number of hard connections, reducing the volume of the electrical control cabinet, lowering material costs, simplifying wiring, saving time, and reducing the cost of labor.

The present disclosure describes an apparatus including an air purifier having a housing. In some examples, the air purifier includes an intake and an outlet. According to some examples, the intake and the outlet are connected by an air passage. The air purifier may include a filtration system comprising a plurality of filters. In some examples, the filtration system is configured such that an airflow enters the air passage through the intake, passes through each one of the plurality of filters subsequent to entering the intake, and exits the air passage through the outlet subsequent to passing through the plurality of filters. According to some examples, the plurality of filters comprises a chemical adsorption filter.

A portable air purifier may include a housing having an accommodation space formed therein and including an inlet through which air is suctioned and an outlet through which air is discharged, a filter installed at an inside of the housing that faces the inlet, a fan module installed at the inside of the housing that faces the outlet, a filter case in which the filter is detachably installed and which is disposed between the filter and the fan module and configured to guide movement of air from the filter to the fan module, and a sanitizing portion mounted on the filter case and configured to irradiate sanitizing light toward the filter.

A laundry treating apparatus is disclosed. The laundry treating apparatus includes a cabinet configured to define a receiving space for receiving laundry, the cabinet having an open surface, a door hingedly provided at the cabinet for opening and closing the open surface of the cabinet, a laundry support unit provided in the receiving space for supporting laundry, and a machinery compartment provided in the cabinet for defining a space that is separate from the receiving space, the machinery compartment being provided therein with an air supply unit for dehumidifying or heating air in the receiving space and supplying the dehumidified or heated air into the receiving space. The air supply unit dehumidifies air in a room that communicates with the receiving space in the state in which the door is open.

A heat exchange unit performs at least one of a cooling and a heating of a liquid medium that is sent to a utilization side equipment. The heat exchanging unit includes: a heat exchanger that exchanges heat between a flammable refrigerant and the liquid medium; a casing that accommodates the heat exchanger; a drain pan with a bottom plate and a side wall that extends upward from the bottom plate; and a first gas detection sensor that detects presence or absence of a gas of the refrigerant in an internal space of the drain pan. The internal space is a space within the drain pan that is surrounded by the bottom plate, the side wall, and a virtual plane passing through an upper end part of the side wall. The drain pan is disposed below the heat exchanger in a lower part of the casing.

An air-conditioning apparatus includes: a housing having a first space and a second space that are adjacent to each other; a fan provided in the first space and to suck air into the housing; a heat exchanger provided in the first space and cause heat exchange with the air sucked by the fan to be performed; a refrigerant sensor provided in the second space and to detect refrigerant; and a partition plate provided to partition off the first space and the second space and having an air inlet port and an air outlet port.

An outdoor unit includes a housing that includes a front panel and a back panel facing the front panel. The outdoor unit further includes a bell mouth provided on the front panel and a heat dissipator that dissipates heat generated by electric components. A windward end surface and a leeward end surface of the heat dissipator are, when viewed from above, placed in a region between a virtual surface and the back panel, the virtual surface being a virtual surface that is in contact with an end of the bell mouth on a side of the back panel and is parallel to an inner surface of the front panel.

A layered control panel for a heating, ventilation, air conditioning, and refrigeration (HVACR) unit includes an outer layer on which low-voltage components are placed, and an inner layer on which high-voltage components are placed. The outer layer is capable of taking a closed position where it blocks access to the inner layer, and an open position where the outer layer does not block access to the inner layer. The outer layer can include a lock to keep the outer layer in the closed position. The outer layer can be one or two or more panels mounted on hinges that allow the outer layer to swing between closed and open positions.

A thermostat assembly powered by line voltage and capable of wireless communication with a heat source, comprising a first portion and a second portion separated by a barrier. The first portion receives power via internal housing wiring at a first high voltage level and converts the power from the first high voltage level to a second low voltage level. The second portion is removably connected to the first portions to receive power at the second low voltage level, which powers at least a temperature sensor that measures an ambient temperature of an outside environment and a communication chip for wireless communication with a primary heat source. The barrier inhibits dissipation of heat between the first and second portions to reduce an effect of a temperature of the first portion on the temperature sensor, and prevents a user from contacting any high voltage components when the second portion is removed.

A heating, ventilation, and air conditioning (HVAC) door assembly includes a first HVAC door rotating about a first axis, a second HVAC door rotating about a second axis that is nonparallel with the first axis, an actuator, a mode cam. The mode cam is engaged with the actuator and controls movement of the first HVAC door and the second HVAC door.
