A piece of temperature tunable clapboard

Technical Field

The invention relates to a kind of temperature controllable baffle, in particular to a can be used in refrigerator, freezer, such as in household appliances, can be to the the isolation of the upper and lower compartments of the temperature of the baffle.

Background Art

In the prior refrigerator, Figure 1 shows a household refrigerator, the refrigerator equipped with a refrigerating chamber, the freezing chamber is arranged on the vertical distance of the drawer for storing frozen articles, heat insulation door is installed on the heat-insulating housing, heat-insulating housing and is in a closed state of the door of the freezing chamber together with the external thermal insulation. The freezer does not have the function of rapid temperature, and the frozen goods, temperature control is not convenient, in addition a single freezing chamber, the user is not met the needs of the different temperature of the frozen goods.

However, in the refrigerator of the prior art, there is no disclosure of use of plug-in spacer and the internal compartment of the refrigerator, at the same time, also to the divided chamber and the temperature of the literature.

Content of the invention

The invention aims to solve the technical problem of overcoming to the prior art, provides a can be used in refrigerator, freezer, such as in household appliances, can be to the the isolation of the upper and lower compartments of the temperature of the baffle.

In order to solve the above technical problem, the invention adopts the technical proposal, the basic idea is:a kind of temperature controllable baffle, including: a baffle, which is mainly characterized in that, in the on the baffle of the cover is provided with at least one, is arranged in the ventilation ports a plurality of blades, the blade can be opened and closed is formed in order to open and close ventilation ports.

By means of the vane on the formed shaft can rotate the blades to rotate the opening and closing of the vent.

The vanes on the vane is inserted into the ventilation ports rotating shaft in the shaft hole on the side wall, and can be rotated.

The opening and closing of the vanes of the screw-type driving mechanism,

The screw-type driving mechanism comprises a screw rod, the screw rod and a blade, the blade rings is meshed with the outside of the rotating shaft, and is connected with the output shaft of the stepping motor, when the step-by-step when the motor is rotated, the rotation of the screw, so as to drive the rings rotate, the external fixed ring rotating shaft of the blades, so as to drive the rotating shaft to rotate the blade, blade rotating shaft drives the blade to about 90 degrees of movement.

The blades of the driving connecting rod driving mechanism.

The connecting rod driving mechanism comprises a connecting rod, the connecting rod on the blade on the blade shaft and is connected with the upright post, the blade column can rotate in the shaft hole.

The connecting rod and the electromagnetic driver is connected.

The electromagnetic driver can be used for two-way mobile, thus can control rotation of the vane, through the rotation of the vane, for opening and closing the ventilation ports, in order to regulate the temperature to the refrigerating capacity of a chamber below the clapboard.

The cover is on and/or under protective joists.

Combining the Figure below Mode of execution of this invention for further detailed description.

Mode of execution

Embodiment 1

This embodiment of the adjustable temperature baffle 7 structure, as shown in Figure 2, the invention the adjustable temperature separator 7 includes: a partition plate, the partition board is provided at least one of the cover 23, the cover 23 provided with a plurality of vanes in 14, blade 14 with the help of the blades of the rotation shaft 15 can be spin-forming cover 23 opening and closing.

Embodiment 2

This embodiment and other embodiment 1 the same, however, this embodiment adopts a screw-type driving mechanism, as shown in Figure 3, the invention has the advantages of the screw-type driving mechanism comprises a screw rod 17, screw 17 and the blade 14 is, sleeved on the vanes to rotate shaft 15 passing outside the 18 engaged, the screw 17 and the stepping motor 16 is connected with the output shaft, when the stepping motor 16 rotates, the screw 17 to rotate, so as to drive the rings 18 to rotate, rings 18 is sleeved and fixed on the blade rotating shaft 15 is, so as to drive the the vanes to rotate shaft 15 rotating, vane rotating shaft 15 drives the blade 14 as 90 degrees of movement.

Through the vane 14 rotating, the air outlet 23 opening and closing, in order to regulate the to can be baffle 7 the lower part of the refrigerating capacity of a chamber (see Figure 5).

Embodiment 3

This embodiment and other embodiment 1 the same, however, this embodiment adopts the connecting rod driving mechanism, as shown in Figure 4, the invention of the connecting rod driving mechanism comprises a connecting rod 19, connecting rod 19 and the shaft hole of the blade 14 on the blade column 20 is sleeved, blade column 20 can be rotated in the shaft hole.

The connecting rod 19 and the electromagnetic driver 21 is connected.

Blade 14 blade on the rotating shaft 15 is inserted in the cover 23 in the shaft hole on the side wall, and can be rotated.

Since the electromagnetic driver 21 can be used for two-way mobile, to control the blade 14 rotating, through the vane 14 rotating, the air outlet 23 opening and closing, in order to regulate the to can be baffle 7 of the lower part of the refrigerating chamber.

Other to make the connecting rod 19 to move back and forth mechanism can also be applied to this embodiment.

Embodiment 4

The same as other and the aforesaid embodiment, different is that, in order to prevent the articles are placed in the can be baffle 7 obstructs or damaged on the opening-closing structure, as shown in Figure 5, the cover 23 is provided with a protective joists 22, and the negative second surface can also be provided with a protective joists 22.
