Characterized in that it comprises a.

The present invention as described above has the effect that the user can put the food in the refrigerator and know when the food will be cooled to cool in advance to use the timely extraction of chilled or frozen food.

In addition, the present invention indicates the time to be cooled, but if the user wants faster cooling without waiting until that time, the cooling time expected in normal operation by setting the cooling time or by selecting the rapid cooling mode by the user's selection It has the effect of cooling faster.

Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to the cooling time display and cooling rate control apparatus and method according to the present invention. 1 is a block diagram of a cooling time display and a cooling rate adjusting device of a first embodiment according to the present invention.

As shown in Figure 1, the cooling time display and the cooling rate adjusting device 10 according to the present invention is a sensing unit 20 for detecting the air volume and temperature, calculating the cooling time based on the detection value of the sensing unit Cooling time calculation unit 30, the display unit 40 for displaying the calculated cooling time, the cooling time setting unit 50 for setting the desired cooling time, the user controls the respective parts and set when the user sets the cooling time It is provided with a control unit 60 for adjusting the operation rate of the compressor to achieve cooling in time.

 The detector 20 detects a change in air volume and temperature in the refrigerated store when food is added. When food is put in the freezer or refrigerator compartment of the refrigerator, the temperature in the refrigerator rises due to the heat of the food and the air volume changes. The sensor detects these changes in height.

The sensing time detected by the sensing unit 20 is transferred to the cooling time calculator 30, and the cooling time of the food is calculated based on the sensing value. When the refrigerator is in normal operation, the temperature discharged from the EVA (evaporator) into the freezer compartment (F chamber), the temperature introduced from the freezer compartment (F chamber), the temperature discharged from the refrigerator compartment (R chamber), and flows into the refrigerator compartment (R chamber). The temperature is constant because the temperature is in equilibrium. At this time, when the temperature and the air flow changes due to the food input, the cooling time calculation unit calculates the time to reach the equilibrium state based on the detection value transmitted from the detection unit.

The display unit 40 displays the calculated cooling time. In addition, a message is sent to guide you to set the cooling time.

 The cooling time setting unit 50 is configured to set the desired cooling time when the user wants to cool more quickly without cooling the refrigeration time of the food put in by the normal operation. When the user desires faster cooling by looking at the expected cooling time displayed on the display unit, the cooling time is set through the cooling time setting unit. If the user is not interested in fast cooling, the cooling time will not be set separately. In this case, cooling is performed by normal operation.

When the user sets a desired cooling time, the controller 60 controls the operation rate of the compressor to be increased within the set time so that the cooling is performed within the set time.

2 is a block diagram of a cooling time display and a cooling rate adjusting device according to a second embodiment of the present invention. As shown in FIG. 2, the second embodiment has the same configuration as that of the first embodiment, and replaces only the cooling time setting unit 50 with the rapid mode selection unit 70. As shown in FIG.

The rapid mode selection unit 70 is to allow the user who wants faster cooling after selecting the expected cooling time of the food to be selected, rather than setting the desired time. When the rapid mode is selected, the controller controls the operation rate of the compressor so that the rapid mode is performed.

3 is a flowchart of a cooling time display and a cooling speed adjusting method of the first embodiment according to the present invention. As shown in Figure 3, the cooling time display and the cooling rate control method according to the present invention measures the air flow rate and the internal temperature when the food is put into the refrigerator (S310). It is to measure the temperature and air volume changed by the food input.

Next, the cooling time of the food is calculated on the basis of the measured air volume and the internal temperature (S320). Calculate the time it takes for a change in temperature, etc., to reach equilibrium.

Next, the calculated cooling time is displayed and allows the user to select whether to set a desired cooling time (S330). It calculates the time it takes for food to cool and displays it to the user, and allows the user to select whether to set a desired cooling time for faster cooling.

Next, if the user does not set the cooling time is a normal operation, if the cooling time is set to control to increase the operation rate of the compressor to achieve cooling within the set time (S340). Users who do not need particularly fast cooling need only reference the expected cooling time and do not need to set a cooling time otherwise. Therefore, if no time is set, the food will be cooled by normal operation. However, when the user sets the desired cooling time, the control unit increases the operation rate of the compressor and controls the cooling to be performed within the set time.

4 is a flowchart of a cooling time display and a cooling speed adjusting method of a second embodiment according to the present invention. As shown in Figure 4, the cooling time display and the cooling rate adjustment method according to the present invention is the same as most of the first embodiment, but if the user wants to cool the food faster it is to set the desired time It only differs in that it allows cooling by selecting the rapid mode.

The cooling time display and cooling rate control apparatus and method of the present invention having such a configuration calculates and reports the cooling time when the user puts food so that the user does not wonder when the cooling will be timely and timely The food can be extracted and used, and if the user wants faster cooling, the user can set the desired cooling time or select the rapid mode to cool the food faster.

The present invention relates to a cooling time display and a cooling rate control device and method, and calculates and displays the cooling time of the food put into the refrigerator, it is possible to select faster cooling for users who can not wait for the expected cooling time Useful at
