[0003] For built-in home appliances, such as dishwashers, which are basically grounded and installed at a height below waist level, it is inconvenient for users to exert force when unlocking or opening the door, whether they bend over or squat down, which affects the user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a household appliance with a door lock to facilitate opening the door, in light of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a household appliance with a door lock, comprising:

[0006] The main body of the electrical appliance has an open chamber inside, and the direction of the open chamber is defined as forward.

[0007] An electrical door is provided at the opening of the electrical body to close the opening, and the electrical door is arranged to rotate about a first axis extending to the left and right or adjacent to the lower edge to open the opening.

[0008] A handle extending to the left and right is located on the front side of the electrical appliance door;

[0009] A lock body is located at the opening of the electrical appliance body and has a lock opening;

[0010] The latch is connected to the electrical door body, and the first end of the latch is inserted into the lock mouth to restrict the rotation of the electrical door body;

[0011] Its features are:

[0012] A through hole penetrating the wall thickness of the electric appliance door body is provided, and a transmission rod is inserted into the through hole. The middle of the transmission rod is supported on the lower edge of the through hole and takes the supporting part as a fulcrum. The first end of the transmission rod is located on the front side of the electric appliance door body and is connected to the above-mentioned handle, so that the handle can rotate up and down around the above-mentioned fulcrum. The second end of the transmission rod is located on the rear side of the electric appliance door body and acts on the lock tongue to convert the upward rotation power of the handle into the movement of the lock tongue relative to moving away from the lock opening and getting out of the restraint of the lock opening.

[0013] In this way, when unlocking is required, pulling the handle upward can make the lock tongue move relative to moving away from the lock opening and get out of the restraint of the lock opening. Then, applying force to the handle can open the electric appliance door body forward, which is convenient for opening the door.

[0014] Preferably, the lock tongue is arranged in the mounting seat on the rear side of the electric appliance door body in a manner that can move up and down, and the first end portion of the lock tongue faces upward and is inserted into the lock opening of the lock body from bottom to top.

[0015] The transmission rod is arranged to convert the upward rotation power of the handle into the downward movement of the lock tongue.

[0016] Further, the second end of the transmission rod is folded backward to form a rotating shaft extending left and right, and a jack for inserting the rotating shaft is provided in the lock tongue. Thus, the upward rotation power of the handle can drive the lock tongue to move downward through the transmission rod.

[0017] To improve the structural stability, further, there are at least two transmission rods, which are arranged at intervals in the left - right direction. The number of through holes on the electric appliance door body and the number of jacks on the lock tongue match the number of transmission rods.

[0018] Preferably, the upper end surface of the first end portion of the lock tongue has a downward inclination from front to back. So as to facilitate the first end portion of the lock tongue to extend into the lock opening.

[0019] In the above - mentioned various solutions, the lock tongue can move relative to moving closer to the lock opening and extend into the lock catch under the drive of the downward - rotating handle. The handle can rotate downward under the external force of the user or under its own gravity. Preferably, an elastic member is further included, which acts on the lock tongue to make the lock tongue always have a tendency to move relative to moving closer to the lock opening and make the handle rotate downward to the initial position.

[0020] To improve the stability of the overall structure, preferably, the lock tongue is in an "I" shape as a whole, having an intermediate part that cooperates with the second end of the transmission rod, a first strip - shaped part extending upward from the center of the upper end surface of the intermediate part, and a second strip - shaped part extending downward from the center of the lower end surface of the intermediate part. The upper end part of the first strip - shaped part is the first end portion of the lock tongue.

[0021] The elastic element is a spring, which is circumferentially sleeved on the outer periphery of the second strip portion, with the upper end of the spring acting on the lower end face of the middle portion and the lower end of the spring supported on the bottom surface of the mounting base.

[0022] Preferably, the shape of the mounting base matches the shape of the locking tongue.

[0023] Preferably, the fulcrum is relatively close to the first end of the transmission rod and relatively far from the second end of the transmission rod. This allows the locking tongue to move with only a small rotation of the handle.

[0024] In the above solutions, the household appliance can be a steamer, oven, disinfection cabinet, etc. Preferably, the household appliance is a washing machine that can wash dishes and chopsticks, and the cavity of the main body of the appliance is provided with a spray mechanism that can spray water.

[0025] It also includes a micro switch and a controller electrically connected to the micro switch. The output of the controller is electrically connected to the spray mechanism. The micro switch is located on the movement path of the locking tongue and is triggered after the locking tongue disengages from the lock. Thus, the spray mechanism can be controlled to stop working after the locking tongue disengages from the lock.

[0026] Compared with the prior art, the advantages of this utility model are as follows: by setting a through hole in the electrical door body, and inserting a transmission rod through the through hole, the middle part of the transmission rod is supported on the lower edge of the through hole and uses the support part as a fulcrum. The first end of the transmission rod is located on the front side of the electrical door body and is connected to the handle, and the second end of the transmission rod is located on the rear side of the electrical door body and acts on the lock tongue. When it is necessary to unlock, pulling the handle upward will cause the lock tongue to move away from the lock opening and break free from the lock opening constraint. Then, force is applied to the handle to open the electrical door body forward, making it easy to open the door. Attached Figure Description

[0031] Figure 5 This is a schematic diagram of the structure of the electrical appliance body according to an embodiment of the present utility model. Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-5 As shown, this is a preferred embodiment of a household appliance with a door lock according to the present invention. The household appliance is a washing machine that can wash dishes and chopsticks, and includes an appliance body 1, an appliance door 2, a handle 3, a lock body 4, a lock tongue 5, a mounting base 6, an elastic element 7, a micro switch 8, and a controller.

[0034] Among them, such as Figure 5 As shown, the main body of the electrical appliance 1 has a chamber with an opening 10 on the front. A water spraying mechanism 11 is installed inside the chamber. The spraying mechanism 11 is prior art and will not be described in detail here.

[0035] The aforementioned electrical door 2 is located at the opening 10 of the electrical body 1 to close the opening 10. The electrical door 2 is arranged to rotate around a first axis extending to the left and right or adjacent to its lower edge to open the opening 10. The electrical door 2 has two through holes 20 penetrating its own wall thickness, spaced apart on the left and right. A transmission rod 21 passes through each through hole 20. The middle part of each transmission rod 21 is supported on the lower edge of the through hole 20, with the support portion serving as a fulcrum 210. The first end of each transmission rod 21 is located on the front side of the electrical door 2, and the second end is located on the rear side of the electrical door 2, with the second end folded back to form a left-right extending pivot 211. In this embodiment, the fulcrum 210 is relatively closer to the first end of the transmission rod 21 and relatively farther away from the second end of the transmission rod 21.

[0036] The handle 3 extends to the left and right and is located on the front side of the electrical door 2, connected to the first end of the two transmission rods 21, so that the handle 3 can rotate up and down around the fulcrum 210.

[0037] The aforementioned lock body 4 is located at the upper edge of the opening 10 of the electrical appliance body 1, and has a lock opening 40 that runs vertically through the body.

[0038] The above-mentioned locking tongue 5 is arranged in the mounting seat 6 at the rear side of the electrical appliance door body 2 in a manner that it can move up and down. The first end portion 51 of the locking tongue 5 faces upward and is inserted into the locking port 40 of the lock body 4 from bottom to top to restrict the rotation of the electrical appliance door body 2. In this embodiment, the upper end surface 511 of the first end portion 51 of the locking tongue 5 is inclined downward from front to back. At the same time, the locking tongue 5 is generally in the shape of a Chinese character 'zhong', having an intermediate portion 5a, a first strip portion 5b extending upward from the center of the upper end surface 511 of the intermediate portion 5a, and a second strip portion 5c extending downward from the center of the lower end surface of the intermediate portion 5a. The upper end portion of the first strip portion 5b is the first end portion 51 of the locking tongue 5. The intermediate portion 5a is provided with insertion holes 52 for the rotation shafts 211 on the two transmission rods 21 to be inserted, so that the transmission rod 21 can convert the upward rotation power of the handle 3 into the downward movement of the locking tongue 5 to release the constraint of the locking port 40. The shape of the mounting seat 6 matches the shape of the locking tongue 5.

[0039] The above-mentioned elastic member 7 acts on the locking tongue 5 so that the locking tongue 5 always has a tendency to move upward, causing the handle 3 to rotate downward to the initial position. In this embodiment, the elastic member 7 is a spring, which is sleeved around the outer circumference of the second strip portion 5c in the circumferential direction. The upper end of the spring acts on the lower end surface of the intermediate portion 5a, and the lower end of the spring is supported on the bottom surface of the mounting seat 6.

[0040] When unlocking is required, pulling up the handle 3 can make the locking tongue 5 move downward to release the constraint of the locking port 40. Then, applying force to the handle can open the electrical appliance door body 2 forward, facilitating door opening. After the electrical appliance door body 2 is closed, the locking tongue 5 moves upward under the action of the elastic member 7 and is inserted into the locking port 40.

[0041] The cleaning machine in this embodiment is installed in an embedded manner and grounded. The height of the cleaning machine is lower than the waist of the human body. In this embodiment, since pulling up the handle 3 can unlock, there is no need for the user to squat or bend over excessively, which is a labor-saving operation.

[0042] As Figure 3 、 4 shown, the above-mentioned microswitch 8 is supported on the bottom surface of the mounting seat 6 and is located below the locking tongue 5 (i.e., on the moving path of the locking tongue 5) and is triggered after the locking tongue 5 disengages from the locking port 40. The above-mentioned controller is electrically connected to the microswitch 8 and is also electrically connected to the spraying mechanism 11 to control the operation of the spraying mechanism 11. Specifically, when the locking tongue 5 disengages from the locking port 40, the controller controls the spraying mechanism 11 to stop working. When the locking tongue 5 is inserted into the locking port 40, the controller can control the spraying mechanism to work.
