This application is a U.S. national stage application of PCT/JP2017/027074 filed on Jul. 26, 2017, the contents of which are incorporated herein by reference.
The present invention relates to an outdoor unit of an air-conditioning apparatus provided with a holder that accommodates a temperature-measurement unit that measures the outside air temperature.
There is known some outdoor unit of an air-conditioning apparatus provided with a holder that accommodates a temperature-measurement unit that measures the outside air temperature. For example, Patent Literature 1 discloses a holder mounted onto a heat exchanger that has a single-row structure or a multi-row structure and that is disposed inside a housing that forms an outline of an outdoor unit and the holder extends along an end portion at the rear surface of the housing. This holder includes a main body portion that accommodates a thermistor that is the temperature-measurement unit and a cover portion that is pivotally hinged to the main body portion. The main body portion includes a hook unit that engages the heat exchanger by sandwiching an upper end portion of the heat exchanger in a front-rear direction.
Patent Literature 1: Japanese Unexamined Patent Application Publication No. 2007-147205
In a configuration, such as the configuration of the holder disclosed in Patent Literature 1, in which a hook unit engages a heat exchanger by sandwiching an upper end portion of the heat exchanger in the front-rear direction, the dimensions of the hook unit are specified in accordance with the width dimension of the heat exchanger, and thus, the hook unit cannot be mounted on a heat exchanger having a different width dimension. In other words, in some outdoor units of air-conditioning apparatuses, for example, a holder used for an outdoor unit of an air-conditioning apparatus that includes a heat exchanger having a two-row structure cannot be applied to another outdoor unit of an air-conditioning apparatus that includes a heat exchanger having a single-row structure, and consequently, it is necessary to manufacture a holder for each outdoor unit in such a manner that the dimensions of the holder correspond to the width dimension of a heat exchanger included in the outdoor unit. Thus, for some outdoor units of air-conditioning apparatuses, it is necessary to prepare a manufacturing mold for each holder shape, and the manufacturing costs may increase. In addition, it is burdensome to manage different types of holders by classifying the holders by their types, and this management operation is a heavy burden for an operator.
The present invention has been made to solve such problems described above, and it is an object of the present invention to provide an outdoor unit of an air-conditioning apparatus capable of using a holder that is the same as a holder used for another outdoor unit that includes a heat exchanger having a width dimension different from the width dimension of a heat exchanger included in the outdoor unit.
An outdoor unit of an air-conditioning apparatus according to an embodiment of the present invention includes a housing forming an outline of the outdoor unit, a partition plate extending from a front surface of the housing toward a rear surface of the housing and partitioning an interior of the housing into an air-sending device chamber and a machine chamber, a heat exchanger disposed in the air-sending device chamber and along an end portion located at the rear surface of the housing, and a holder mounted on the heat exchanger and accommodating a temperature-measurement unit configured to measure an outside air temperature. The partition plate includes a first flat portion disposed with a space between a rear surface of the first flat portion and the heat exchanger and extending in a longitudinal direction of the heat exchanger, and a second flat portion projecting from a side edge portion of the first flat portion toward the heat exchanger. The holder includes an accommodating unit holding the temperature-measurement unit, and a hook unit formed continuous with the accommodating unit, the hook unit extending across a top surface of the heat exchanger and being hooked to the first flat portion.
According to an embodiment of the present invention, a partition plate may be formed through adjusting the length of a second flat portion, so that the space between a first flat portion and a heat exchanger can fit the shape of a holder, and thus, an outdoor unit can use a holder the same as a holder that is used for another outdoor unit including a heat exchanger whose width dimension is different from the width dimension of a heat exchanger included in the outdoor unit.
An embodiment of the present invention will be described below with reference to the drawings. Note that, in the drawings, portions that are the same as each other or that correspond to each other are denoted by the same reference sign, and descriptions of the portions will be suitably omitted or simplified. In addition, shape, size, arrangement, and other characteristics in the configurations illustrated in the drawings can be suitably changed within the scope of the present invention.
An outdoor unit of an air-conditioning apparatus according to the embodiment of the present invention is configured to be capable of using a holder the same as the holder of a temperature-measurement unit that is used for another outdoor unit including a heat exchanger whose width dimension is different from the width dimension of a heat exchanger included in the outdoor unit according to the present embodiment. For this reason, in the present embodiment, a case will be described as an example in which a holder that is the same as the holder used for an outdoor unit 110 of an air-conditioning apparatus that includes a heat exchanger having a two-row structure is used for an outdoor unit 100 of an air-conditioning apparatus that includes a heat exchanger having a single-row structure.

Note that, in the embodiment illustrated in the drawings, although a case has been described as an example in which the holder 5 that is the same as the holder 5 used for the outdoor unit 110 of an air-conditioning apparatus, which includes the heat exchanger 30 having a two-row structure, can be used for the outdoor unit 100 of an air-conditioning apparatus, which includes the heat exchanger 31 having a single-row structure, the configuration is not limited to this case. In the outdoor unit 100 of an air-conditioning apparatus according to the present embodiment, the partition plate 9 may be formed through adjusting the length of the second flat portion 91, so that a holder that is the same as a holder used for one outdoor unit of an air-conditioning apparatus that includes a heat exchanger having a three-row structure can also be used for another outdoor unit of an air-conditioning apparatus that includes a heat exchanger having a single-row structure. In addition, a holder that is the same as a holder used for one outdoor unit of an air-conditioning apparatus that includes a heat exchanger having a single-row structure can be used for another outdoor unit of an air-conditioning apparatus that includes a heat exchanger having a single-row structure and having a width dimension different from that of the heat exchanger included in the one outdoor unit.
As described above, with the outdoor unit 100 of an air-conditioning apparatus of the present embodiment, the housing 1 that forms the outline of the outdoor unit 100, the partition plate 9 that extends from the front surface toward the rear surface of the housing 1 and that partitions the interior of the housing 1 into the air-sending device chamber 3 and the machine chamber 4, the heat exchanger 31 that is disposed in the air-sending device chamber 3 and along the end portion located at the rear surface of the housing 1, and the holder 5 that is mounted on the heat exchanger 31 and that accommodates the temperature-measurement unit 8 configured to measure the outside air temperature. The partition plate 9 includes the first flat portion 90 that is disposed with the space S provided between the rear surface of the first flat portion 90 and the heat exchanger 31 and that extends in the longitudinal direction of the heat exchanger 31, and the second flat portion 91 that projects from the side edge portion of the first flat portion 90 toward the heat exchanger 31. The holder 5 includes the accommodating unit 6 that accommodates the temperature-measurement unit 8, and the hook unit 7 that is formed continuous with the accommodating unit 6 and that extends across the top surface of the heat exchanger 31 and is hooked to the first flat portion 90.
Consequently, the partition plate 9 may be formed through adjusting the length of the second flat portion 91, so that the space S between the first flat portion 90 and the heat exchanger 31 can fit the shape of the holder 5, and thus, the outdoor unit 100 of an air-conditioning apparatus according to the present embodiment can use the holder 5 that is the same as the holder 5 used for the outdoor unit 110, which includes the heat exchanger 30 having a width dimension different from the width dimension of the heat exchanger 31. With the outdoor unit 100 of an air-conditioning apparatus according to the present embodiment, when the holders 5 are manufactured, only a few manufacturing molds therefore need to be prepared for the shapes of the holders 5, and the manufacturing costs can be kept low. In addition, the burden of managing different types of the holders 5 by classifying the holders 5 by their types can be reduced.
The partition plate 9 further includes the third flat portion 92 that projects from the side edge portion of the second flat portion 91 in the longitudinal direction of the heat exchanger 31. Thus, in the outdoor unit 100 of an air-conditioning apparatus according to the present embodiment, the partition plate 9 can be fixed in place by bringing the third flat portion 92 into contact with the heat exchanger 31 and joining the third flat portion 92 and the heat exchanger 31 to each other by using a fastening part, such as a screw.
The hook unit 7 of the holder 5 includes the extended-surface portion 70 that extends from the accommodating unit 6 and that is in contact with the rear surface of the heat exchanger 31, the top-surface portion 71 that extends and is bent from the end portion of the extended-surface portion 70 and is placed on the top surface of the heat exchanger 31, and the hook portion 72 that extends and is bent from the end portion of the top-surface portion 71 and hooked to the first flat portion 90. The hook portion 72 has the end portion 72a, which is inclined outward. Thus, in the outdoor unit 100 of an air-conditioning apparatus according to the present embodiment, the end portion 72a of the hook portion 72 is used as a guide portion that guides the holder 5 toward the first flat portion 90 when the holder 5 is mounted onto the heat exchanger 31, and this configuration facilitates an operation of mounting the holder 5, so that the operational efficiency can be improved.
Although the present invention has been described above with reference to the embodiment, the present invention is not limited to the configuration according to the above-described embodiment. For example, each of the configurations of the outdoor units of air-conditioning apparatuses that are illustrated in the drawings is an example, and the configuration is not limited to the above-described contents.
