Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.

As shown in fig. 1 and 2, the present invention provides a compartment of a refrigerator, a space in the compartment 2 is divided into a first section 201 and a second section 202, wherein the first section 201 is communicated with a cold air duct 203, that is, the first section 201 is a freezing chamber, and a heating device 204 (or no heating device is provided, and the second section 202 is a normal temperature thawing section) is provided on an inner wall of a top of the second section 202, and can heat food materials to be used as a thawing chamber. Still be equipped with the matter storage lattice in the compartment 2, the position of matter storage lattice can switch between first interval 201 and the interval 202 of second, and when food need unfreeze, can switch the matter storage lattice from first interval 201 to the interval 202 of second and unfreeze, realizes the function of unfreezing in the refrigerator, does not influence the refrigeration simultaneously again.

In a specific embodiment, a rotatable circular tray 402 is arranged in the compartment, a heat-insulating partition plate 406 which divides the tray 402 into two parts is arranged in the middle of the tray, meanwhile, the heat-insulating partition plate 406 also divides the space in the compartment 2 into a first section 201 and a second section 202, the storage compartment 401 is placed on the tray 402 and is positioned on one side of the partition plate 406, and the storage compartment 401 is semicircular, so that the space of the tray can be utilized to the maximum extent.

The tray 402 is driven by the driving device 403 to rotate around the center of the tray 402, the driving device 403 may be a driving motor installed at the bottom of the tray, the tray is driven to rotate by a rotating shaft of the driving motor, and the specific connection mode may be a gear or a mode directly connecting with the axis, which is not particularly limited.

In order to improve the user experience, the invention also comprises: the controller can acquire the manual preset thawing starting time set by the refrigerator, when the preset thawing starting time is reached, the controller controls the driving device to switch the storage compartment 401 from the first interval 201 to the second interval 202, and the heating device 204 and the blowing device 205 are started to thaw the food materials in the storage compartment 401. The user can set the thawing time in advance, and the user experience is improved.

Specifically, first interval and second interval set up side by side, and all adjacent with compartment door, convenience of customers takes, also can set to first interval and be close to compartment door, and the second interval is kept away from compartment door, perhaps other forms.

The pressure sensor 404 is arranged on a supporting surface of the tray 402 supporting the storage grid 401, and is used for weighing the weight value of the food material and sending a food material weight signal to the controller, and the controller acquires the weight of the food material through the food material weight signal and calculates the thawing duration according to the weight of the food material. Avoid unfreezing incompletely or unfreeze excessive and lead to eating material scorching and influence taste. There are various calculation schemes for the thawing duration, which can be based on a heat formula as illustrated in detail

Calculating the heat quantity required by the unfreezing of the frozen food; wherein c is the specific heat capacity of the unfrozen food (the type of the food material to be unfrozen can be selected by a user before unfreezing, and the controller obtains the preset specific heat capacity corresponding to the food material), Δ t is the temperature difference (the temperature difference between the food material before heating and the food material after heating), m is the weight of the unfrozen food, the heat required for unfreezing is calculated through the heat formula, and then the unfreezing time required by the whole unfreezing process can be calculated according to the heating power of the heating device. The thawing duration may also be calculated by other manners, for example, dividing the weight of the food material into a plurality of ranges, and setting a first thawing duration corresponding to each range.

In order to avoid uneven unfreezing, the blowing device 205 is arranged at the corner between the top and the side wall of the second section 202 and is turned on and off along with the heating device 204, and hot air in the unfreezing cavity (the second section 202) is subjected to circulation interference through a fan of the blowing device 205 during heating, so that even unfreezing of food materials is guaranteed.

The heating device 204 may be an electric heating device or a microwave heating device, and it is within the scope of the present invention to heat the food.

When the thawing completion time is reached, the controller closes the heating device 204 and the blowing device 205, and determines whether the corresponding weight value of the weight signal of the food material changes more than a preset change rate within a preset time (the preset change rate can be set to 70% to 90%), if not, most or all of the food materials are not taken out, and a user may forget to take out the food material, at this time, the controller drives the driving device 403 to switch the storage compartment 401 from the second interval 202 to the first interval 201, that is, to switch the storage compartment from the thawing chamber back to the freezing chamber, so as to re-freeze the food material, thereby preventing the food material from going bad.

As shown in fig. 3, for easy understanding, the specific flow of the embodiment of the present invention is as follows:

after food materials are put into the freezing cavity (the first interval), the pressure sensor sends a food material weight signal to a main control board (namely a controller); the main control board calculates the thawing duration required by thawing and acquires the preset thawing starting time set by a user;

when the preset thawing starting time is reached, driving a sensor (namely a sensor for timing) to generate a signal to a main control board, controlling a motor of a driving device to drive a tray to rotate by the main control board, switching the storage compartment to the freezing cavity, and controlling a heating device and a blowing device to start for thawing;

when the calculated thawing time, namely the thawing completion time, is reached, the main control board closes the heating device and the blowing device, and displays a prompt signal on a display screen of the refrigerator to remind a user of thawing completion;

judging whether the weight value corresponding to the weight signal of the food material changes more than a preset change rate within a preset time (namely whether the pressure value is greatly reduced), wherein the preset time can be specifically set to be half an hour or longer; if so, the food materials are taken out, the cold air duct of the chamber is closed, and the operation is completely stopped; if not, the food material is not taken out, the driving sensor is driven to send a signal to the main control board after the preset time is reached, the main control board controls the driving device to work, the storage grid is rotated to the first interval from the second interval, and freezing and refreshing are carried out again.

The invention also provides a refrigerator comprising the compartment. As shown in fig. 4, the compartment is provided between the refrigerating compartment and the freezing compartment of the refrigerator, and does not affect the temperatures of the refrigerating compartment and the refrigerating compartment.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
