Description

  The present invention relates to a technical field of a cooler, and more particularly, to a power transmission structure of a drainage device of a cooler.

  Cooling air conditioners, i.e., coolers, are now home appliances that need to be deployed in homes and offices, and as a result, air conditioners that meet a variety of different environments and requirements have evolved, such as window-mounted coolers, separate coolers and There is a mobile cooler. However, in any cooler, the effect of cold air delivery is achieved by the heat exchange principle between the cooling pipe and the heat exhaust pipe. In such a use process, the cooling pipe constantly in agglomerated water, whatever the cooler for this it is necessary to also design the cooling water discharge.

  Among them, with regard to the separation type cooler, the drainage device of the traditional separation type indoor air conditioner is supposed to discharge the wastewater directly through the drain pipe, but since the water flows downward, the indoor air conditioner is attached. At times, the height of the indoor air conditioner must be taken into account so that the drain can smoothly drain the drainage down. For this reason, the installation of the indoor air conditioner is subject to considerable restrictions, and further affects the interior design of the room, and the drain pipe is not properly disposed, which adversely affects the appearance. In order to solve such a problem, the present applicant has provided a cold water built-in automatic drain device of a separation type cooler in Patent Document 1, which is a water storage connected to a drain pipe on one side of an indoor air conditioner. A box is installed, a water extraction motor and a water level detector are installed in the water storage box, and a water pipe is connected to the water storage box so that drainage is discharged to the outside by the water pipe. Such a design solves the problem that the cooling groove cannot be discharged unless the drain pipe is inclined downward, but it creates noise and aesthetic problems.

  According to the well-known technology, since the extraction motor is installed in the indoor air conditioner, some noise is generated when the motor is operated (especially at night). One of the disadvantages in use is formed, and since the water extraction motor is installed in the indoor air conditioner, when the drain pipe cannot be pulled out, a water collection tank must be installed indoors. Worsens and creates inconvenience in the placement of the conduit. There is a so-called separation type cooler in which a water bleeder is provided outside and the condensed water discharged from the indoor unit by the operation of the water traction motor is extracted and discharged to the outside. Otherwise, the drainage operation cannot be performed, and the space for installing such a water extractor and the cost of assembling production and energy use increase, which is not the best design structure.

  Next, in response to the rise of environmental protection consciousness and legal restrictions, another so-called “non-drop water” structure, for example, a non-drop water separation type air conditioner of Patent Document 2 and a non-drop water separation type of Patent Document 3 A cooler is provided. The technical means used in Patent Documents 2 and 3 use a water conduit, discharge the condensed water generated by the indoor unit into the outdoor unit, store it, and send the condensed water to the cooling end by blowing air from the fan to evaporate. This eliminates the need to discharge condensed water to the outside of the room, thus solving the problem of condensed water discharge.

  However, in the techniques of these two patent documents, in order to smoothly send condensed water to the outdoor unit, it is necessary to install the indoor unit above the outdoor unit for assembly, so that the condensed water passes from the top to the bottom through the water pipe. When the water drops in the water collection tank and the condensed water in the water collection tank reaches a certain height, the fan rotates to repel water and sends it to the cooling end by blowing air. These two known patents achieve the purpose of drip-free water in use, but they must be installed above the outdoor unit for installation of the indoor unit. Even if the machine is installed at a suitable place in the room, the transportation of condensed water is further inconvenient when it is located on a different plane from the position of the outdoor unit.
