Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Example 1
The embodiment provides a cold and hot separated glass door display cabinet, as shown in fig. 1 and 2, which comprises a glass door display cabinet body, wherein a main condenser 6, a compressor 4, a gas-liquid separator 1 and a temperature controller are arranged on the outer side of the glass door display cabinet body. The inside of the glass door display cabinet body is provided with a foaming layer clapboard 14, and the inside of the glass door display cabinet body is divided into a heating chamber 10 and a refrigerating chamber 11 by the foaming layer clapboard 14.
The top of the heating chamber 10 is provided with an auxiliary condenser 5, an auxiliary condensing fan 13 and a first temperature probe. The top of the refrigeration chamber is provided with an evaporator 2, an evaporation fan 12 and a second temperature probe; the temperature controller is connected with the compressor 4 in a control way.
One end of the auxiliary condenser 5 is connected to the compressor 4 through a normally open solenoid valve 8. One end of the main condenser 6 is connected to the compressor 4 through a second normally closed solenoid valve 9; the secondary condenser 5 and the main condenser 6 form two parallel condensation paths.
The other end of the auxiliary condenser 5 and the other end of the main condenser 6 are both connected with one end of a throttling element 3, the other end of the throttling element 3 is connected with one end of the evaporator 2, and the other end of the evaporator 2 is connected with the gas-liquid separator 1 in series and then is communicated with the compressor 4.
The gas-liquid separator 1 is also directly communicated with the other end of the auxiliary condenser 5 and the other end of the main condenser 6 through a first normally closed electromagnetic valve 7.
The glass door display cabinet is characterized in that a fixed support plate for fixing the evaporator 2 and the auxiliary condenser 5 is further arranged inside the glass door display cabinet body.
The glass door display cabinet body is also provided with two split doors, and one of the two split doors is respectively arranged corresponding to the heating chamber 10 and the refrigerating chamber 11.
Specifically, the working process of the cold-hot separated glass door display cabinet is as follows:
the first stage is as follows:
when the glass door display cabinet normally starts to work, the first normally closed electromagnetic valve and the second normally closed electromagnetic valve are both in a closed state, and the corresponding system branch is in an open circuit.
At this time, the refrigerant passes through the auxiliary condenser and the evaporator, and the evaporator is positioned in the refrigerating chamber because the auxiliary condenser is positioned in the heating chamber; when the refrigerant flows through the auxiliary condenser, the heat is radiated by the auxiliary condensing fan, and the hot air blown out by the auxiliary condensing fan uniformly raises the temperature of the heating chamber, so that the food is heated.
Meanwhile, when the refrigerant flows through the evaporator of the refrigerating chamber, the refrigerating function of the refrigerating chamber can be realized through the evaporation fan.
And a second stage:
since the heating chamber and the cooling chamber need to be controlled separately, a single or both of them may meet the temperature condition, and thus, it is necessary to control them in different cases. The following three cases are shown:
(1) when the temperature probe in the heating chamber detects that the temperature reaches a set value, on the premise that the temperature in the refrigerating chamber does not reach the standard, the heating in the heating chamber needs to be stopped in time, and meanwhile, the refrigerating chamber needs to continue to refrigerate. The specific operation process is as follows:
the method comprises the steps that firstly, a temperature controller is used for controlling a normally open electromagnetic valve connected with an auxiliary condenser in series to be closed, and meanwhile, a second normally closed electromagnetic valve connected with a main condenser in series is opened, so that a refrigerant flows through the main condenser and an evaporator outside a cabinet body, heating is stopped at the moment, and refrigeration is continued.
(2) When the temperature probe in the refrigerating chamber detects that the temperature reaches a set value, the heating chamber needs to be stopped in time and the heating chamber needs to be continuously heated on the premise that the temperature of the heating chamber does not reach the standard. The specific operation process is as follows:
the temperature controller controls the first normally closed electromagnetic valve to be opened, so that little refrigerant can continuously flow through the evaporator due to the existence of the throttling element, namely the refrigeration function is disconnected, and the heating function is continued.
(3) When the temperatures of the refrigerating chamber and the heating chamber reach the standard, the temperature controller controls the compressor to stop.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
