Description

The present invention relates to a stand-alone air conditioner.

A stand-alone air conditioner is an air conditioner that does not have an outdoor unit and uses only the air conditioner itself for heating and cooling. In a normal single-unit air conditioner, drain water is always generated from one of the cooling radiators when cooling and heating. The drain water is supposed to flow to the lower part of the air conditioner and be discharged from the drain port, but the installation location of the stand-alone air conditioner is limited because drainage may not be possible depending on the installation location.

The stand-alone air conditioner, also called a floor-standing type, does not have an outdoor unit, and usually has two radiators for heat exchange in the same body. The compressor type air conditioner used in the stand-alone air conditioner generates drain water during both heating and cooling.
Therefore, in a stand-alone air conditioner, drain water that is always generated during operation regardless of heating or cooling flows to the lower part of the machine and collects in a tray or the like inside the machine. If it accumulates too much inside, it will malfunction. Therefore, it is necessary to take some measures such as removing the tray and draining the drain water manually, or draining it to the outside of the machine using a hose or the like. However, manual drainage is time-consuming, and if you forget it, it will overflow from the tray and flow out into the cabin, causing trouble. Draining to the outside of the machine with a hose may be difficult depending on the installation status of the stand-alone air conditioner, and even if it is possible, problems may occur in the installation of windows and hoses for draining to the outside. be.
Due to these problems, there are many cases where the advantage of a stand-alone air conditioner, which can be easily installed anywhere, cannot be fully utilized.

However, the air conditioner of Patent Document 1 is premised on draining drainage outdoors, and the above problem cannot be solved.

In view of the above problems, it is an object of the present invention to provide an air conditioner capable of easily and surely draining drainage of a stand-alone air conditioner.

In order to solve the above problems, the invention of claim 1 is an air conditioner, which is an ultrasonic evaporator that evaporates drain water generated from a radiator for heat exchange, and a water level of drain water accumulated in the air conditioner machine.

According to the present invention, a stand-alone air conditioner capable of automatically and surely draining drain water even under conditions where an outdoor unit cannot be installed is provided.

It is a schematic diagram which shows the 1st Embodiment of the stand-alone air conditioner of this invention. It is a schematic diagram which shows the 2nd Embodiment of the stand-alone air conditioner of this invention.

Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. First, the configuration of this embodiment will be described.

As shown in FIG. 1, the stand-alone air conditioner 10 of the present embodiment has an ultrasonic evaporator 4 that evaporates the drain water 3 generated from the radiators 1a and 2a for heat exchange, and the drain water 3 that has accumulated in the main body 10. It is provided with a water level sensor 5 for detecting the water level of the water level and fans 1b and 2b for discharging the evaporated water 6. The radiators 1a and 2a are for cooling and heating, respectively, and the fans 1b and 2b are fans for blowing the radiators 1a and 2a, respectively.
The power source (not shown) of the ultrasonic evaporator 3 is the same as the power source (not shown) of the fans 1b and 2b.

Next, the function of the stand-alone air conditioner of the present embodiment will be described.
Drain water regardless of whether the radiator 1a and the fan 1b are operating during the operation of the stand-alone air conditioner 10, that is, during cooling, or when the radiator 2a and the fan 2b are operating during heating. 3 is accumulated in the tray 7 in the machine. In either case of cooling or heating, the radiator 1a and the radiator 2a are in operation and are in a cooled and heated state. Only the fan 1b is used during cooling and the fan 2b is used during heating. By operating only, cold air is supplied to the room during cooling and warm air is supplied during heating.
The drain water 3 collected in the tray 7 is detected by a water level sensor 5 such as a float switch (buoyancy switch), and when a predetermined water level is reached, the ultrasonic evaporator 4 operates according to the information of the water level sensor 5, and the drain water 3 As shown in FIG. 1, the evaporated water 6 is discharged to the outside of the machine by the fan 1b during cooling, and is discharged to the outside of the machine by the fan 2b during heating.
The ultrasonic evaporator 4 and the fan 1b or 2b are interlocked with each other, and the fan 1b (during cooling) or 2b (during heating) is set to operate whenever the ultrasonic evaporator 4 operates. As a result, the evaporated water 6 is surely discharged to the outside of the machine.

Next, a second embodiment of the present invention will be described.
First, the configuration of this embodiment will be described.
The air conditioner of the present embodiment is called a water-cooled air conditioner, and as shown in FIG. 2, it is provided with only a radiator 1a and a fan 1b, and only cools the air conditioner.
The function is the same as that of the first embodiment, and the drain water 3 collected in the tray 7 is detected by a water level sensor 5 such as a float switch (buoyancy switch), and when a predetermined water level is reached, the water level sensor 5 is used to detect the drain water 3. The sonic evaporator 4 operates to evaporate the drain water 3, and the evaporated water 6 is discharged to the outside of the machine by the fan 1b.
Further, in the first or second embodiment, as a means for evaporating the drain water 3, a method of atomizing with a spray nozzle by the pressure of a pump (not shown) or stirring with a motor (not shown) to make fine water droplets is formed. Other means, such as methods, may be used.

In any of the embodiments, conventionally, if neither the drain water collected in the tray can be manually discharged or the drain water hose can be discharged, the installation of the stand-alone air conditioner itself has to be abandoned. However, for example, even in places where drainage from walls and windows is difficult, and even under conditions where manual drainage is difficult, if a stand-alone air conditioner can be installed, we would like to install it and perform air conditioning without the burden of installation work. There is a need. That is, the discharge of drain water is a major constraint when installing an air conditioner.

As described above, the present invention realizes an air conditioner having no drainage restriction, that is, a so-called non-drainage air conditioner, by converting drain water from a liquid into water mist or vapor and discharging it into the air.
As a concrete measure, a tray for collecting drain water is installed inside the air conditioner, an ultrasonic evaporator is installed, and in conjunction with the float switch in the tray, ultrasonic evaporation occurs when the predetermined water level is reached. The mechanism is such that the ultrasonic evaporator is stopped when the drain water level drops to a predetermined position due to evaporation by operating the vessel.

In an air conditioner, when air conditioning is performed, a fan is moved to exchange heat to generate wind that passes through a radiator, so that an air flow is formed inside the air conditioner. The fog generated by the evaporation of drain water is discharged to the outside of the air conditioner by utilizing the air flow during heating and cooling. Due to the configuration of the air conditioner, the fan is the device with the longest operating time, and the fan is supposed to operate for most operations such as cooling, heating, dehumidification, ventilation, etc. By linking with the power supply and configuring the fan to operate whenever the ultrasonic evaporator operates, drainage efficiency can be maximized and drain water can be reliably distributed to the outside of the machine. can.
INDUSTRIAL APPLICABILITY The present invention provides a stand-alone air conditioner that solves the above-mentioned problems and can be easily installed without being restricted by the installation location.
