Benefits of technology

This patent describes a freezer with a clapboard to adjust temperature, a fast cooling chamber, and air return openings that can be opened and closed. The freezer also has a control method and a top board with a pad for easy wine pouring. The pad has skid-proof raised dots for easy handling of items. The fast cooling chamber has an air outlet pipe and the air return openings can be opened or closed to adjust the temperature. The freezer also has a control panel with temperature display screen and control keys for adjusting temperature. The invention allows for separate control of the clapboard and air return openings, keeping the fast cooling chamber and upper and lower chambers at different temperatures. The top of the freezer has a bar for placing wine cups and bottles, which can be easily accessed without opening the freezer door. This reduces energy waste and saves time.

Problems solved by technology

The freezer does not have the function of fast temperature changing in addition to the inconvenience of temperature control during putting in and taking out the frozen items.
Besides, the single freezing chamber can not meet the demands on different temperatures for the user to keep frozen items.

embodiment 1

[0031]As shown in FIG. 2, groove 16 is set on the top board 14. The said pad 15 for placing wine cups and bottles and for easy wine pouring is set in groove 16. As shown in FIGS. 3, 4, and 5, one side of pad 15 is decorated surface 19 and the other side is divided into two parts. One part is pressed step shaped groove 17 and the other is flat plate 18. The surface of the said flat plate 18 is flat for easy taking out and putting in pad 15. At least one handle slot 20 is set at one side of said pad 15. The best position is the opposite side of step shaped groove 17 on flat plate 18. Water guiding groove 22 is set at the periphery of flat plate 18. (See FIG. 3).

[0032]As shown in FIG. 3, holed-clapboard 21 is set on the said step shaped groove 23, on which users can place wine cup and pour wine, with the spilled wine flowing into stepped groove 17 through the holes. Water guiding groove 22 at the periphery of the said flat plate 18, integrated with stepped groove 17. Wine spattered on ...

embodiment 2

[0034]The structure of clapboard to adjust temperature 7 explained in this embodiment is shown in FIG. 6. The clapboard to adjust temperature 7 includes a board with front and back sealed with tape 13 (only front sealing tape is shown), making the front part joint glass door body 27 (see FIG. 2) and the back joint the internal wall of the chamber to separate the upper and lower spaces for constant temperatures in the two temperature zones (see FIG. 7). Clapboard 7 can be adjusted between the upper and lower ribs, realizing the changing of the upper and lower spaces. When different amounts of red wine and wine are kept, the spaces can be adjusted freely, realizing the division of different temperature zones. Air return openings are set in the upper and lower temperature zones, for one each, so the temperatures of the upper and lower spaces can be controlled independently, without interfering each other.

embodiment

[0035]This embodiment is a kind of fast cooling chamber of freezer.

[0036]The freezer mentioned in this invention is a air cooling one, on which normally has one ventilation opening. Fan 11 is set as shown in FIG. 7. Air return opening 8 is placed at a proper position in the freezer. Cold air is blown out by fan 11 from air return opening 8 and enters freezing zone through air return opening 8. Air contacts the evaporator in the freezing zone to have the circulating air temperature decreased.

[0037]Fast cooling chamber 10 mentioned in this invention is set optimally on the top of the freezer according to the common place of the ventilation opening.

[0038]The said fast cooling chamber 10 includes air outlet pipe 12. Pipe 12 is fixed on the wall of the freezer, just wrapping the air outlet as shown in the figures. The rear end of outlet pipe 12 in U shape for obtaining enough strength is fixed on the rear wall of the freezer, with the upper side fixed on the upper part inside the freezer...

Abstract

This invention disclosed a freezer; and it's control method. The freezer includes the casing and the top board, on which a pad for placing wine cups and bottles and for easy wine pouring is equipped. There is a fast cooling chamber at the ventilation opening of the freezer, and a clapboard to adjust temperature is placed in the freezer, dividing the freezer into two chambers vertically. Air return openings are equipped above and beneath the clapboard. The said fast cooling chamber includes an air outlet pipe. The pipe is fixed on the wall of the freezer, just wrapping the ventilation opening. The said clapboard to adjust temperature includes a board, sealed with tapes at both front and back, making the front part joint the glass door and the back part joint the internal wall of the freezer. At the same time, the air return opening can be open or closed dependent on need to form different temperature control of the fast cooling chamber and the two chambers.

Description

BACKGROUND OF THE INVENTION[0001]This invention disclosed a freezer, including a casing with a top board, an internal box, and a heat insulation case with heat insulation layer between the two. In the freezer, there is a freezer chamber sealed by a heat insulation door. The temperature of the freezing chamber is detected by a temperature sensor.[0002]In particular, on the said top board, there is a pad for placing wine cups and bottles and easy wine pouring. In the said freezer, there are a clapboard to adjust temperature, fast cooling chamber, and the air return opening that can be open and closed. Temperatures in the upper and lower chambers, and the fast cooling chamber can be adjusted respectively to meet the different temperature needs.PRIOR ART[0003]According to the prior art, FIG. 1 shows a household freezer, equipped with a freezing chamber. Drawers are set vertically in the freezing chamber for frozen items. The heat insulation door is installed on the heat insulation case....
