Definitions
- the present invention relates to air conditioners.
- the operation of an air conditioner is controlled so that indoor temperature reaches a preset temperature.
- the air conditioner includes an indoor temperature detector for measuring the temperature of indoor air.
- an indoor temperature detector is disposed in the airway of indoor air taken into an indoor heat exchanger to measure the temperature of the indoor air taken into the indoor heat exchanger.
- the indoor temperature detector is disposed in the airway of the indoor air in this way, it can accurately measure the temperature of the indoor air, although it obstructs the flow of the intake air taken into the indoor heat exchanger, thus causing pressure loss of the intake air and decreasing air-conditioning efficiency.
- the indoor temperature detector is disposed in front of or near the indoor heat exchanger, it cannot accurately detect the indoor temperature because of the effect of radiant heat from the indoor heat exchanger.
- an air conditioner including an insulating member surrounding an indoor temperature detector disposed to the side of an indoor heat exchanger to block radiant heat from the radiant heat source has been proposed.
- the indoor temperature detector surrounded by the insulating member is so bulky that it obstructs the flow of the intake air, thus causing pressure loss of the intake air and decreasing air-conditioning efficiency.
- an object of the present invention is to provide an air conditioner including an indoor temperature detector that can accurately detect indoor temperature without obstructing an airway, thus preventing a decrease in air-conditioning efficiency.
- an air conditioner of the present invention employs the following solutions.
- an aspect of the present invention is an air conditioner including a base equipped with an indoor heat exchanger, a front panel detachably attached to the front of the base and having an opening for taking in indoor air in a front surface thereof, a cover member attached to the base so as to cover one side of the indoor heat exchanger to prevent scattering of condensed water occurring on the indoor heat exchanger, and an indoor temperature detector attached to the base on the side of the cover member facing away from the indoor heat exchanger.
- the indoor air is taken in through the opening of the front panel to flow into the indoor heat exchanger.
- the airway of the indoor air is formed so as to extend from the outside of the front panel, that is, from around the edges of the opening, to the indoor heat exchanger through the opening.
- the cover member is attached to the base so as to cover one side of the indoor heat exchanger, and the indoor temperature detector is attached on the side of the cover member facing away from the indoor heat exchanger.
- the indoor temperature detector is disposed inside the front panel and is located to the side of the indoor heat exchanger. This means that the indoor temperature detector is not located in the airway.
- the indoor temperature detector is not located in the airway of the intake air, it does not obstruct the flow of the intake air. This prevents pressure loss of the intake air, thus preventing a decrease in air-conditioning efficiency due to pressure loss.
- the cover member which prevents scattering of condensed water occurring on the indoor heat exchanger, at the same time blocks radiant heat radiated from the indoor heat exchanger. Because the indoor temperature detector is attached on the side of the cover member facing away from the indoor heat exchanger, the cover member can prevent the radiant heat from the indoor heat exchanger from reaching the indoor temperature detector. Thus, if the indoor temperature detector is insulated from the radiant heat from the indoor heat exchanger, it can directly detect the temperature of the indoor air, so that it can accurately measure the temperature of the indoor air. This allows operation control based on the accurate temperature of the indoor air, thus improving air-conditioning efficiency and the conditioned air feeling.
- the front panel preferably has a through-hole formed near the indoor temperature detector so as to penetrate the front panel.
- the indoor air flows in through the through-hole, and the indoor temperature detector measures the temperature of the indoor air flowing in. This allows the indoor temperature detector to more accurately measure the temperature of the indoor air.
- the indoor temperature detector may be attached to a front surface of a control box attached to the base and containing components for controlling operation.
- control box contains or is equipped with a controller for controlling the operation of the air conditioner based on various signals from, for example, the indoor temperature detector, signal wiring can be easily installed.
- control box is often disposed to the side of the indoor heat exchanger and is firmly attached to the base, the control box is appropriate as the attachment position of the indoor temperature detector, in other words, complies with the installation conditions of the indoor temperature detector.
- the indoor temperature detector is attached on the side of the cover member, attached to the base so as to cover one side of the indoor heat exchanger, facing away from the indoor heat exchanger, the indoor temperature detector does not obstruct the flow of the intake air. This prevents a decrease in air-conditioning efficiency due to pressure loss.
- the cover member insulates the indoor temperature detector from the radiant heat from the indoor heat exchanger, it can accurately measure the temperature of the indoor air.
