Abstract

The utility model discloses an electronic door lock on an electric steamer, which comprises an electric steamer box, a return spring, a lock rack, an electromagnet, a lock hook and a steamer door. The 'L'-shaped lock rack is made of metal and fixedly mounted at a proper position of the electric steamer box, the electromagnet is fixedly mounted on the upper side of the lock rack, the lock hook is made of iron, an open groove is arranged on the head of the lock hook, the lock hook is mounted on the upper side of the electromagnet, a proper distance is maintained between the lock hook and the electromagnet, the rear side of the lock hook is embedded in a groove of the lock rack so as to guarantee that the lock hook can move vertically on the lock rack, and the return spring is connected between the lock hook and the lock rack. A square slotted hole is arranged on the steamer door, the width and the length of the square slotted hole are slightly larger that the size of the section of the lock hook, and the square slotted hole is disposed at such a position that the lock hook can be guaranteed to be rightly inserted into the steamer door when the steamer door is closed. The electronic door lock with the structure can conveniently lock or unlock the steamer door of the electric steamer by changing the electrification state of the electromagnet.

Description

Electronic lock on the electric steam furnace

Technical field

The utility model relates to the cooking apparatus safety device, specifically refers to a kind of electronic lock that is contained on the electric steam furnace.

Background technology

The modern kitchen device category is maked rapid progress, novel kitchen electrical equipment is also accepted by increasing consumer, I invented the box electric steam furnace of a kind of normal pressure (200820137718.5) in 2008, because of liking of its delicious consumers in general of firmly getting of food nutrition that cook out.But do not adorn locking device on the electric steam furnace, fire door just can arbitrarily be opened when machine works like this, though the machine intimate maximum temperature has only 100 degree, the steam of inside can outwards be gone out when opening, might to the user particularly children cause scald.In view of the foregoing, a kind of locking device being installed on electric steam furnace seems by being necessity.

Summary of the invention

The objective of the invention is: a kind of simple, suitable, safe electric steam furnace door lock is set on electric steam furnace.

The scheme of technical solution problem of the present invention is: a kind of electronic lock of electric steam furnace, comprise the electric steam furnace casing, back-moving spring, lock frame, electromagnet, latch hook and fire door, the lock frame is made " L " type by metal material, it is fixedly mounted on electric steam furnace casing appropriate location, in the upper fixed of locking frame electromagnet is installed.Latch hook is made by iron material, head has the top that open trough is installed in electromagnet, and keeps suitable distance, the rear of latch hook to be embedded in the groove of lock frame, guarantee that latch hook can move up and down by lever type on the lock frame, the back-moving spring two ends are connected between latch hook and the lock frame.Have its length and width size of square slotted eye on the fire door and be slightly larger than the latch hook sectional dimension, the position of square slotted eye guarantees that lock hook just inserts wherein when fire door is closed.It is a kind of simple in structure, with low cost, safe and reliable electric steam furnace door locking device.

Description of drawings

Fig. 1 is that the present invention is located at the location drawing in the casing;

Fig. 2 is the enlarged drawing of circle part among Fig. 1

Each several part title and mark among the figure: 1. electric steam furnace casing, 2. back-moving spring, 3. electromagnet, 4. lock frame, 5. latch hook, 6. fire door.

The specific embodiment

As depicted in figs. 1 and 2, " L " type support that lock frame (4) is made by sheet metal, it is installed in described electric steam furnace casing (1) appropriate location, adopts the engage thread fixed connection.Described magnetic valve (3) is fixedly mounted on the top of described lock frame (4), described latch hook (4) is made by iron material, its head has open trough, be arranged on the top of electromagnet (3) and keep suitable distance, the rear of latch hook is embedded in the recessed groove of lock frame (4), guarantee that latch hook (5) can move up and down by lever type on lock frame (4), the two ends of described back-moving spring (2) are installed in (between latch hook (5) and the lock frame (4).

When electric steam furnace was not worked, described electromagnet (3) was not charged, and following upwards steeves latch hook (5) in the pulling force effect of back-moving spring (2), and the head of at this moment closing fire door (6) latch hook (5) just is inserted in the square groove of fire door (6).The charged generation magnetic of electromagnet (3) when electric steam furnace is worked, because latch hook (3) made by iron material, it moves down under the effect of electromagnet (3) magnetic, and at this moment the open trough of latch hook (3) head just is stuck in the square groove on the fire door (6), be buckling state, fire door 6 is locked.Electromagnet when electric steam furnace quits work (3) is charged and lost magnetic, and latch hook (5) returns original position under the pulling force effect of back-moving spring (2), be the opening-wide state fire door and can freely open again.

Claims

1. the electronic lock on the electric steam furnace, comprise electric steam furnace casing (1), back-moving spring (2), electromagnet (3), lock frame (4), latch hook (5) and fire door (6), it is characterized in that locking frame (4) and make " L " type by sheet metal, it is fixedly connected by engage thread and electric steam furnace casing 1, electromagnet (3) is fixedly mounted on lock frame (4) top, latch hook (5) is made by the metallic iron material, its head has uncovered square groove, be installed in the top of electromagnet (3), and keep suitable distance, the rear of latch hook (5) is embedded in the groove of lock frame (4), guarantee that latch hook (5) can move up and down by lever type on lock frame (4), the two ends of back-moving spring (2) are connected between latch hook (5) and the lock frame (4).
