Abstract

PURPOSE:To eliminate the case in which both air blasts that are blown out from a blast circuit on the indoor side of an air conditioner and blast circuit of a ventilation fan hit a human body at the same time and make it possible to hold pleasantness by the constitution that the blast circuit on the indoor side of the air conditioner is sucked from the front face and blown out from the floor face and the blast circuit from the ventilation face is sucked from the front face and blows out from the upper face. CONSTITUTION:The air for room-cooling and room-heating is sucked from the upper section of the front face of the main body 1 of an indoor machine and blown out from the lower section of the front face. And, the exhaust blast is sucked from the front face and supply air is blown out from the upper face. Here, the air that is sucked from a suction port 2 exchanges heat in an indoor heat exchanger 6 and blown out from a diffuser 3 by a cross-flow fan 7. The exhaust air from the indoor is sucked from the suction port 4 of a ventilation fan by a sirocco fan 9 and passes through a total heat exchange element 8, and then exchanges heat with the outdoor air and then is discharged to the outside of the room. And, the suction air from the outdoor is sucked from the outdoor by a sirocco fan 10 and passes through the total heat exchange element 8 and exchanges heat with the indoor air, and then is supplied into the room from the diffuser 5 of the ventilation fan. Since in this arrangement the directions of the two diffusers 3 and 6 are different, no unpleasantness is felt by the human body.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a separate air conditioner.

BACKGROUND ART Conventionally, this type of air conditioner equipped with a ventilation fan had a structure as shown in FIG.

That is, the air conditioner's suction port 2 is located at the front of the indoor unit main body 1, the air outlet 3 is located at the lower front or bottom surface, and the ventilation fan's suction port 4 and air outlet 5 are located at the front of the main body 1. ing.

Problems to be Solved by the Invention However, with this type of structure, the air blown from the ventilation fan may reach the space where people are living, and the temperature difference between the air and the air blown from the air conditioner can be felt to be large. It causes an unpleasant sensation to the human body.

Furthermore, if the room temperature control sensor of the air conditioner is located at the air intake port 2 of the air conditioner, the air blown out from the ventilation fan is likely to be sucked into the air conditioner, and the room temperature control sensor may not detect the room temperature but erroneously detect the outside temperature. This was causing the problem to occur.

Therefore, the purpose of the present invention is to accurately detect the room temperature even when the ventilation fan is in operation, so that the wind from the air conditioner and the wind from the ventilation fan do not hit the human body at the same time and cause discomfort. It is.

A means for solving the problems and a technical means of the present invention for solving the above-mentioned problems is that the suction port of the ventilation fan is arranged in the front of the indoor main body, and the outlet is arranged in the upper surface.

For production The effect of this technical means is as follows.

In other words, the indoor wind circuit of an air conditioner sucks in from the front and blows out from the bottom, and the wind circuit of a ventilation fan sucks in from the front and blows out from the top, so the air blown from both sides does not mix, creating a comfortable environment. You can maintain your sexuality.

Furthermore, because the ventilation fan's outlet and the air conditioner's inlet are far apart, the sensor for room temperature control will not falsely detect the outside temperature.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIG. 1 is a perspective view of a separate air conditioner according to an embodiment of the present invention.

In FIG. 1, 1 is the indoor unit main body constituting the air conditioner, 2 is the intake port of the indoor unit main body 1, 3 is the same outlet,
Number 4 is the inlet of the ventilation fan, number 5 is the outlet, and the arrows indicate the flow of each wind.

Here, air for heating and cooling is sucked in from the upper front of the indoor unit main body 1 and blown out from the lower front. Also, exhaust air is sucked in from the front, and supply air is blown out from the top.

FIG. 2 is a side sectional view of a heating and cooling section of a separate air conditioner according to an embodiment of the present invention, where 6 is an indoor heat exchanger and 7 is a cross flow fan. Here, the air sucked in from the suction port 2 undergoes heat exchange with the indoor heat exchanger 6, and is blown out from the air outlet 3 by the cross flow fan 7.

Furthermore, FIG. 3 is a plan sectional view of a ventilation fan portion of a separate air conditioner according to an embodiment of the present invention, in which 8 is a total heat exchange element, 9 and IC1t sirocco fan, 11 is sirocco fan 9.10t-driving fan It's a motor. Furthermore, solid line arrows indicate the flow of air from indoors to outdoors, and dashed line arrows indicate air flows from outdoors to indoors. Here, the exhaust air from the room is sucked in by the sirocco fan 9 from the suction port 4 of the ventilation fan, passes through the residual heat exchange element 8, exchanges heat with the outside air, and then is exhausted to the outside. In addition, air from outside is drawn in from the outside by the sirocco fan 10, passes through the residual heat exchange element 8, exchanges heat with inside air, and then is supplied into the room from the ventilation fan outlet 5.

Effects of the Invention As is clear from the above embodiments, the present invention has the advantage that the air blown out from the ventilation fan may directly hit the human body, and the directions of the two air outlets are different, so two types of air with different temperatures can be generated. are not mixed. Therefore, air conditioning can be performed without causing discomfort to the human body.

Furthermore, since the outlet of the ventilation fan and the intake of the air conditioner for heating and cooling are separated, there is no need to worry about the suction sensor for controlling air temperature erroneously detecting the temperature of the outside air blown out by the ventilation fan.

Furthermore, by providing the ventilation fan with a total heat exchange element, the heat of the exhaust air can be recovered, resulting in an energy saving effect.
