technical field

The utility model relates to an accessory mechanism of a household appliance, in particular to an embedded supporting device of the household appliance.

Background technique

Usually, larger household appliances such as microwave ovens and ovens are placed on the desktop or other horizontal platforms when in use; and when not in use, they are either stored in the cabinet or still placed on the horizontal platform. If it is stored in the cabinet, it needs to be taken in and out frequently, which not only brings certain troubles to the user, but also affects the service life of the household appliance; if it is still placed on the horizontal platform, it will occupy a larger space , affect people to carry out other activities, and even have the possibility of accidentally knocking over the electrical appliance.

Utility model content

The utility model provides an embedded support device for household appliances. The main purpose of the utility model is to overcome the disadvantages of inconvenient storage and space occupation of existing household appliances placed on desktops or other horizontal platforms.

The utility model adopts the following technical scheme: the embedded supporting device of the household appliance includes a table for supporting the household appliance, and an opening for the household appliance to be embedded under the table is formed on the table, and the table corresponds to the opening below the opening. The position forms a space for accommodating household appliances, and a lifting mechanism is provided in the space, and a supporting platform for supporting household appliances that can rise and fall with the lifting mechanism is provided on the top of the lifting mechanism, and the supporting platform rises to the highest level. Fitting in the opening of the table top when in position. When the lifting mechanism is lowered to the lowest position, the household appliances on the supporting platen will descend with the supporting platen and be embedded under the tabletop. Conversely, when the lifting mechanism rises to the highest position, the supporting platen will rise to be flush with the tabletop. Located above the countertop.

The above-mentioned embedded supporting device for household appliances, its lifting mechanism includes at least two pairs of cross folding rods juxtaposed front and back; two support rods extending downward to the left and right sides are pivotally connected to the pivot shafts of the two rod bodies of each pair of cross folding rods, The lower end of each support rod is respectively pivotally connected to a sliding rod extending forward and backward, and the two sliding rods are respectively slidably arranged in a chute extending left and right, and each sliding rod is pivotally connected to a connecting rod, each The connecting rods respectively extend outwards and upwards, and are respectively connected with the lower ends of the above-mentioned two rod bodies; the two sliding rods are respectively provided with driving devices for driving them to slide in the corresponding chute. When the driving device makes the two slide bars slide in the direction away from each other in the respective chute, the lower ends of the two rod bodies of each pair of cross-folding rods also move in the direction away from each other, so the height of the cross-folding rods becomes smaller, The supporting table is lowered, so that the household appliances placed on the supporting table can be embedded into the space below the table; otherwise, when the driving device makes the two slide bars face to When sliding in one direction, the supporting platen rises, and the household appliances rise to the top of the table.

A pair of extended cross-folded rods are respectively connected above each pair of cross-folded rods, and the lower ends of the two rod bodies of each pair of extended cross-folded rods are respectively pivotally connected with the upper ends of the two rod bodies of the cross-folded rods below each pair. The upper ends of the two rods of the cross folding rods are connected with a W-shaped folding rod group. The two ends of the folding rod group can be slidably connected to the bottom of the table. The middle top corner is pivotally connected to the bottom of the table. The two parts are respectively pivotally connected with the upper ends of the two rod bodies extending the cross folding rod. The extended cross folding rod and the W-shaped folding rod group can increase the lifting height range of the support frame, so as to ensure that the household appliances on the table can be completely retracted below the table.

The driving device includes a reduction motor arranged on the connecting rod, a gear connected to the output shaft of the reduction motor, a rack parallel to the corresponding chute and meshed with the aforementioned gear, and a control for controlling the forward and reverse rotation of the motor. The circuit board and the power switch connected with the circuit board, and the two ends of the chute are respectively provided with limit switches connected with the control circuit board. When the power switch is turned on, the control circuit board controls the motor to rotate forward or reverse, and the lifting device descends or ascends. When the descending or ascending reaches the limit position, the limit switch is touched to stop the ascending or descending.

Further, the geared motor is connected to the connecting rod through a bracket, the bracket is U-shaped, the geared motor is fixed on both sides of the U-shaped bracket, and the bottom of the U-shaped bracket is fixed on the connecting rod. On the rod, the gear is located between the motor and the connecting rod.

The lifting mechanism of the above-mentioned embedded support device for household appliances can also be the following structure, including: rails arranged on both sides of the space for accommodating household appliances and rails arranged on both sides of the support table that can correspond to the two rails.

When the user turns on the power switch, the control circuit board drives the motor to rotate, which drives the screw rod at the bottom of the thread sleeve screw rod assembly to rotate. Since the support table is limited by the track, it can only move up and down but cannot rotate. When the rod rotates, the wire sleeve moves up and down relative to the screw rod, and the support plate moves up and down accordingly. When it touches the limit switch, the control circuit board cuts off the power supply of the motor to make it stop working.

The sliding device is a set of rollers.

The thread sleeve screw assembly includes an upper section, a middle section and a lower section. A cavity that can accommodate the middle section is formed inside the upper section, a thread sleeve is formed at the lower end of the cavity, and a screw rod matched with the thread sleeve is formed on the outer peripheral surface of the middle section. A cavity capable of accommodating the lower section is formed inside the middle section, a thread sleeve is formed at the lower end of the cavity, and a screw rod matched with the thread sleeve is formed on the outer peripheral surface of the lower section. The three-stage structure can make the lifting range of the supporting table larger.

From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: automatic lifting can be realized, and when the household appliance is to be used, the lifting mechanism is raised, and the supporting platform rises to the level of the table surface.
