Abstract

【Task】
In the combustion heater, a hole for discharging the burned air is opened in the wall on the back of the combustion heater, but the position is above the combustion heater. The air conditioner has a problem that the condensed water that passes through the drain hose cannot be drained if the hole that passes through the piping, the power cable, and the drain hose that connect the indoor unit and the outdoor unit is located upward. In addition, since piping and drain hoses are routed from the lower side to the upper hole of the indoor unit, a space is required between the indoor unit and the wall, which causes an appearance problem.
[Solution]
In order to solve the above problems, the present invention includes a drain pump in a floor-mounted indoor unit to forcibly drain condensed water. Moreover, it is providing the space which a connection piping and a drain pump can route around in the back surface of an indoor unit.

Description

  The present invention relates to an air conditioner that drains condensed water generated in a heat exchanger in a floor-mounted air conditioner by a drain pump.

  In the conventional floor-mounted air conditioner, the condensed water generated in the heat exchanger is received in a water tray, and the water tray is provided with a drain hose. At the time of installation, a pipe that connects the indoor unit and the outdoor unit, a power supply cable, and a connection pipe hole through which the drain hose passes are provided in the wall. Did not need.

  Air conditioners that use drain pumps are known for ceiling-embedded types and duct types. A drain pump is used to drain the condensate outside the room, ensuring a slope of the drainage. For example, Japanese Patent Application Laid-Open No. 2003-28455 discloses a ceiling-embedded air conditioner.

JP 2003-28455 A

  When replacing a combustion heating device with a heat pump type air conditioner, it is best to install a floor-standing indoor unit using the location of the combustion heater because it is floor-standing. In the combustion heater, a hole for discharging the burned air is opened in the wall on the back of the combustion heater, but the position is above the combustion heater. The air conditioner has a problem that the condensed water passing through the drain hose cannot be drained if the hole through which the pipe connecting the indoor unit and the outdoor unit, the power cable, and the drain hose pass upward.

  In addition, since piping and drain hoses are routed from the lower side to the upper hole of the indoor unit, a space is required between the indoor unit and the wall, which causes an appearance problem.

  In order to solve the above problems, the present invention includes a drain pump in a floor-mounted indoor unit and forcibly drains condensed water. Moreover, it is providing the space which a connection piping and a drain pump can route around in the back surface of an indoor unit.

  Therefore, by using the above-mentioned means, it is possible to use it as a piping hole of an air conditioner using the exhaust port of an existing combustion heating device at the time of replacement, and it can be connected at any position on the back of the indoor unit. Become. As a result, replacement of combustion heating equipment can lead to an increase in demand for air conditioners.

  Moreover, the beauty of the back of the indoor unit is not impaired.

  FIG. 1 is an overview of the floor-mounted indoor unit of the present invention. An embodiment of the present invention will be described with reference to FIG. The floor-mounted air conditioner 4 is placed on the floor on the indoor side 1 and installed on the wall 3 between the outdoor side 2. The floor-mounted air conditioner 4 includes a blower 5, a heat exchanger 6, and a water tray 10 that receives condensed water generated from the heat exchanger 6, and a drain pump 12 for draining the condensed water in the water tray 10. The drain pump 12 attached with is drained to the outside by the drain hose 8.

  At the time of installation, a high pressure valve 11a and a low pressure valve 11b are attached to the pipe extending from the heat exchanger 6, and a high pressure pipe 9a and a low pressure pipe 9b are connected to the high pressure valve 11a and the low pressure valve 11b. Further, the drain hose 8 is connected to the drain pump 12.

  Conventionally, as shown in FIG. 2, when the connection pipe hole 7 is opened in the wall 3, the drain hose 8 is provided below the water receiving tray so as to have a gradient. Therefore, the drain pump 12 was not necessary. However, when a hole has already been provided in the wall due to replacement of the combustion heating equipment or the like, the drain pump 12 is required to be able to drain water because it is not necessarily below the water tray. Therefore, it becomes possible to use it as a piping hole of the air conditioner by using the exhaust port of the existing combustion heating device at the time of replacement, and it can be connected at any position on the back of the indoor unit.

  The drain pump 12 can be set as an option, for example, and can be used or not used depending on the installation state.

  With respect to the position of the connection pipe hole 7, the connection high-pressure pipe 9 a, the connection low-pressure pipe 9 b and the drain hose 8 are pulled out from the outlet 14 and passed through the connection pipe hole 7 from the floor-mounted air conditioner 4. Thus, an installation space 13 is provided. As a result, the floor-mounted air conditioner can be installed without opening a gap in the wall, and the aesthetic appearance is not impaired.

The external view of the floor-mounted indoor unit in the Example of this invention. The principal part explanatory sectional view of the conventional floor-standing indoor unit. The principal part explanatory sectional view of the floor-standing type indoor unit in the example of the present invention.
