Abstract

According to one embodiment, an outdoor unit is provided with a housing, an outdoor heat exchanger, and a communication unit. The housing has a ventilation opening and contains the outdoor heat exchanger. The communication unit is disposed within the housing at a position facing the ventilation opening and performs contactless data communication with a nearby information terminal.

First claim

What is claimed is:

1. An outdoor unit for a refrigeration cycle apparatus comprising:
a housing comprising a ventilation opening;
an outdoor heat exchanger housed in the housing;
a communication unit which is provided in the housing at a position facing the ventilation opening, and performs contactless data communication with a nearby information terminal;
an electrical component box housed in the housing;
a main control unit which is provided in the electrical component box and connected to the communication unit via a signal line, and which sets data necessary to operate the outdoor unit and diagnoses a state of the outdoor unit based on data communication with the information terminal via the communication unit; and
an outside air temperature sensor which detects outside air temperature;
wherein the communication unit comprises:
a data communication unit which performs the contactless data communication with the information terminal;
a nonmagnetic base portion which holds the data communication unit and the outside air temperature sensor, and comprises a first ventilation opening at a position facing the outside air temperature sensor; and
a nonmagnetic cover portion which covers the data communication unit and the outside air temperature sensor on the nonmagnetic base portion, and comprises a second ventilation opening at a position facing the outside air temperature sensor.

2. The outdoor unit for the refrigeration cycle apparatus of claim 1 , wherein
the communication unit is removably attached to a position facing the ventilation opening in the outdoor heat exchanger.

3. The outdoor unit for the refrigeration cycle apparatus of claim 1 , wherein the communication unit comprises:
a data communication unit which is connected to the main control unit via the signal line, and which operates with electricity generated by electromagnetic induction due to a radio wave transmitted from the information terminal, and performs contactless data communication with the information terminal by a near-field communication technology;
a nonmagnetic base portion which holds the data communication unit; and
a nonmagnetic cover portion which is openably and closably provided in the nonmagnetic base portion, and covers the data communication unit.

4. The outdoor unit for the refrigeration cycle apparatus of claim 3 , wherein the nonmagnetic base portion comprises a groove portion for extending a signal line of the outside air temperature sensor and the signal line from the data communication unit, and the cover portion comprises a signal line cover for covering the groove portion and partially covering the signal lines extending from the groove portion.

5. The outdoor unit for the refrigeration cycle apparatus of claim 3 , wherein the nonmagnetic base portion includes a first holding portion which holds the data communication unit, a second holding portion which holds the outside air temperature sensor, a first ventilation opening formed in the second holding portion, and a frame member formed along a peripheral border of the first holding portion.
