Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner with a built-in heater having residual heat removal functions.

Problems with the configuration of conventional examples Conventionally, in air conditioners, the cooling cycle was basically composed of a J1 compressor, an outdoor heat exchanger, and a reduced Li:r1, +17 inner heat exchanger, while the heating cycle was There are also so-called heater-heating air conditioners on the market that incorporate a heater, exchange electrical energy into thermal energy, and blow air indoors using a fan.

Figures 1 and 2 are a perspective view and a sectional view of an all-white unit of a ceiling-suspended air conditioner, which is an example of a conventional air conditioner, and 1 is an indoor heat exchanger. vessel,
2 is an indoor fan, 3 is a heater, 4 is a water tray, "l 5b
is a heat insulating material, 6 is an inlet, and 7 is an outlet 'C. In order to eliminate residual heat generated by the heater 3 and the indoor heat exchanger 1, the heater 3 and the indoor heat exchanger 1 are installed in the air conditioner with a built-in heater. , for example 2
A method was adopted in which the control circuit configuration was suitable for running for minutes, but when the electric power supply 1 was pulled out from the = -1 current (, t, the power supply to the motor of the indoor horn 2 was In the case of a sheathed heater with a large heat capacity, the area around the heater 3 is overheated due to the amount of heat (residual heat) that the high temperature heater 3 has, and the surrounding area is There was a risk that the insulation U5a, 5b, the water tray 4, etc. would be deformed and damaged.For this reason, it was difficult to increase the capacity of the heater 3.

Purpose of the Invention The present invention solves and overcomes the drawbacks of the prior art.
Directing life 1. The purpose of this company is to provide an air conditioner that can be used in a variety of ways.

Structure of the invention 1 above Therefore, the air conditioner 4 of the present invention is) -1: contraction 1! A refrigeration recycle consisting of an outdoor heat exchanger, a reducing device, and an indoor heat exchanger, a heater, and an energized 11i'i open type inserted between the outdoor heat exchanger and the pressure reducing device N. , a T valve, and a check valve inserted between the outdoor heat exchanger and the compressor No. 11. The liquid refrigerant charged in the outdoor heat exchanger is depressurized by the pressure reducing device when the power is turned off, and is then led out to the indoor heat exchanger.

According to this configuration, when the power to the air conditioner is turned off, the normally closed two-way valve installed on the output side of the outdoor heat exchanger becomes an intermediate valve, and the After the coolant is depressurized by the pressure reducing device, it flows into the indoor heat exchanger, which is heated to a high temperature due to heat radiation from the heater, until the pressure balances. The residual heat around the heater, which is close to , can be divided by υ1.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 33 is a configuration diagram of a refrigeration cycle of an air conditioner according to an embodiment of the present invention, where CM is a compressor, 8[, 1 check valve, 9 is an outdoor heat exchanger, and PS is a pressure swiss f-110
11 is a pressure reducing device, 12 is an indoor heat exchanger, 13 is an accumulator, and 14 is a check valve C.

FIG. 4 is an electrical circuit diagram of an air conditioner according to an embodiment of the present invention, where SWl is a rotary switch, SW2 is a changeover switch that can be switched to position C for cooling and to position 1 for heating by an operation knob, and T1-1. When the room temperature during cooling rises above the set 1st shift, i<l iP<l>
'The room temperature is set during heating. tin J: The sensor operating in the subbl/raining position. Fl is the indoor motor, Vl is the contact V + a. .

1 is an electromagnetic valve that turns on R and b, 1 is a timer that turns on contact -18, V2 is an electromagnetic breaker that turns on contact V2 a, and P S (1 is when the pressure is below the set value. Then 1.- (

Next, I will explain the operation. Switch S to switch to heating operation
When W2 is switched to the 11th position, room! When AA is below the set value, the thermostat switches to the 1st position, and the electromagnetic switch Mg operates to switch to 1*I;'t-I.
Mqa, M<>b is Illt;, for heating) and 9l-
The IC is energized and the indoor fan motor 1-1 is operated.
: A warm breeze can be sent indoors. At this time, the detection pressure horn of the monthly power switch PS installed at the output [1] of the outdoor heat exchanger 9 is set to the setting pressure (for example, 101τylal
G), contact 1) Sa switches to L position,
In the evening when it is closed, the electromagnetic switch R is energized through the contact Ta of the timer T, and the contacts Ra and Rb are closed.

As a result, the electromagnetic switch v2 closes the contact V2a, the outdoor side switch is turned on, the compressor CM starts operating overnight, and the heating operation starts in advance (changeover switch SW2 is set to L).
i (switching to *-F), the outdoor fan motor F2 and compression +jl By operating the CM, the refrigerant can be contained as a supercooled liquid. The reverse l valve 8 is the 7jth one that prevents the backflow of the containment liquid refrigerant.
The amount of refrigerant to be sealed in the outdoor heat exchanger 9 is determined by the set time of the timer 11, which operates in response to the signal of the switch PS (switching to the 1- position of the switch PS). It is determined.

Contact point ``a'' of the Rinawara timer ■ makes a sound as soon as the set time is reached, turns off the 7ti of the electromagnetic switch R that is in the self-holding state, stops the outdoor fan motor F2113 and the compression 43CM, Then, the refrigerant is stopped from being injected into the outdoor heat exchanger 9.If the power plug 15 is suddenly pulled out, the state of the E one-way valve 10, which is closed when energized, becomes 1;11, and the external heat exchanger ηj The refrigerant in the supercooled liquid state that is stored in the container 9 is reduced by 1 in the pressure reducing device 11.
1, then flows into the low pressure indoor heat exchanger 1 Z:12, Iξ3111. '7, the all-inner heat exchanger 12 is heated to a high temperature due to heat radiation from the heater 1] e as latent heat of evaporation.
OJ: It can remove residual heat from the surrounding area.

According to the detailed description of the invention j, sea urchin book 5C, luck nv + fx
