Description

  The present invention relates to a heat pump apparatus including a terminal block that facilitates connection of connection lines while saving space.

  Conventionally, in this type of equipment, a plurality of indoor units, etc., which are electrical components installed at a location apart from the outdoor heat pump device, are connected by a refrigerant pipe and a connection line consisting of a power line and a signal line. In other words, it was operated and cooled and heated. (For example, Patent Document 1)

Japanese Patent No. 5231383

  By the way, in this conventional one, the refrigerant pipes are arranged vertically, but since a plurality of terminal blocks to which the connection wires are connected are arranged horizontally, the connection work of the connection wires is easily performed. However, the heat pump device itself has a problem of increasing its size.

In order to solve the above-mentioned problems, the present invention exposes the configuration from an opening window formed on one side surface of the housing, and electrically connects the electrical components in the housing and the electrical components in a remote place. Bei example a plurality of the terminal block of the plurality of the terminal block at the ones attached to the mounting plate, with arranged vertically the plurality of the terminal blocks in the vertical, of the plurality of terminal blocks each bottom part of the connection line The terminal hole is inclined with respect to the mounting plate so that the insertion hole faces the opening window. The terminal block is inclined toward the opening window with respect to the mounting plate as the terminal block is positioned below. The inclination angle is widened.

As described above, according to the present invention, a plurality of terminal blocks are arranged vertically in the vertical direction, and each terminal block is further inclined with respect to the mounting plate so that the insertion hole of the connecting wire at the bottom faces the opening window direction. As a result, the installation of the terminal block does not take up much space, saving space and preventing the increase in size of the device, and the insertion hole of the connection wire of the terminal block faces the opening window. easier connection to the base, and no risk of cut without connection line bent extreme, with confidence can be used, also, the terminal block slope, the more the terminal block located below, the opening window relative to the mounting plate Since the inclination angle toward the direction is widened, the connection between the lower terminal block and the connection line becomes easier, and the inclination angle of the upper and lower terminal blocks is different. Easy to route and cut by unreasonable routing It is that there is no distribution.

The external appearance perspective view of the heat pump apparatus which shows embodiment of this invention. The external appearance perspective view of the state which removed the cover body of the heat pump apparatus. The expansion perspective view of the principal part. The enlarged side view of the principal part.

The configuration of the heat pump device according to the embodiment of the present invention will be described in detail with reference to the drawings.
Reference numeral 1 denotes a heat pump device that constitutes a heat source device, and a compressor (not shown) that compresses the refrigerant and a high-temperature refrigerant discharged from the compressor are circulated inside the enclosure 2. A condenser (not shown) for exchanging heat between the refrigerant of the refrigerant and a circulating fluid flowing in a heating circuit (not shown), an expansion valve (not shown) for reducing the pressure of the refrigerant flowing out of the condenser, and an expansion valve And an evaporator (not shown) for exchanging heat between the decompressed low-temperature refrigerant and the heat medium flowing in the underground heat circulation circuit, and these are connected in a ring shape.

  Reference numeral 3 denotes an opening window formed on an upper portion of one side surface of the housing 2, and the fixing metal 5 and 6 are fixed to the opening plate 3 with screws 7 in the opening window 3. The two terminal blocks 8 and 9 are fixed vertically and exposed to the outside. The upper terminal block 8 is connected to the bottom of the upper terminal block 8 by lifting the lower part of the fixing bracket 5. The insertion hole 11 of the wire 10 is inclined with an inclination angle of 20 degrees from the mounting plate 4 so that the insertion hole 11 faces the direction of the opening window 3, while the lower terminal block 9 is bent by the fixing bracket 6 in a dogleg shape. The lower terminal block 9 is inclined at an inclination angle of 45 degrees from the mounting plate 4 so that the insertion hole 13 of the connecting wire 12 at the bottom faces the direction of the opening window 3, and the upper and lower terminal blocks 8, 9, the inclination angle is made different, and the inclination angle becomes wider as it goes downward, so that the lower terminal block 9 and the connection line 12 Of connection is further easier, moreover, from the fact that the inclination angle of the upper and lower terminal block 8 and 9 are different, routing of the connection lines 10 and 12 after the connection is of no concern is to expire at the unreasonable routing becomes easier.

  The terminal blocks 8 and 9 are provided with connection portions 14 and 15 for connecting to electrical components such as a compressor, an expansion valve, and a control board (not shown) in the housing 2 via lead wires. In addition, the connection lines 10 and 12 that are power lines and signal lines are connected to the upper and lower terminal blocks 8 and 9 from the outside through the opening window 3, so that the heat pump apparatus 1 is installed at a place away from the heat pump apparatus 1. It is electrically connected to electrical components of a similar heat pump device (not shown) and can be driven and controlled in conjunction with the control board of the heat pump device 1.

  16 is a safety earth leakage breaker mounted on the other side of the mounting plate 4, which is connected to a single-phase 200 V external power source to obtain a power source, and 17 is one side of the housing 2 below the opening window 3. Reference numeral 19 denotes a pipe connection part to which the refrigerant pipe 18 attached to the pipe is connected, and 19 is a cover body that can simultaneously cover the opening window 3 in which the wiring connection is completed and the pipe connection part 17 in which the refrigerant pipe 18 is connected. is there.

  Next, the wiring connection of the heat pump device 1 according to this embodiment will be described. First, the cover body 19 provided on one side surface of the housing 2 of the heat pump device 1 is removed and exposed from the opening window 3. If the connection wires 10 and 12 are inserted and tightened in the upper and lower terminal blocks 8 and 9 with the insertion holes 11 and 13 directed in the direction, the wiring connection is completed, and the power line is connected to the earth leakage breaker 16 and the pipe connection After connecting the refrigerant pipe 18 to the portion 17 and then covering the connecting portion with the cover body 19, the operation is completed.

  In this way, the plurality of terminal blocks 8 and 9 are vertically arranged vertically, and the terminal blocks 8 and 9 are further inclined so that the insertion holes 11 and 13 of the connecting wires 10 and 12 at the bottom face the direction of the opening window 3. As a result, the installation of the terminal blocks 8 and 9 does not take up much space and space is saved, and the increase in size of the device is prevented, and the insertion holes 11 and 13 of the connection wires 10 and 12 of the terminal blocks 8 and 9 are opened. Since it faces the window 3, it is easy to connect with the terminal blocks 8 and 9 of the connecting wires 10 and 12, and the connecting wires 10 and 12 can be used safely without fear of being bent without being extremely bent. .

  In addition, since the inclination of the terminal blocks 8 and 9 is made wider toward the lower side, the connection between the lower terminal blocks 8 and 9 and the connection wires 10 and 12 is further facilitated. Since the inclination angles of the upper and lower terminal blocks 8 and 9 are different, it is easy to route the connection wires 10 and 12 after the connection, and there is no fear that the connection wires 10 and 12 will be cut by excessive routing.
