[0057] As Figures 1 to 15 shown, in the solution of this embodiment, a cabinet - door supporting device is provided, including:

[0058] A supporting mechanism 1, including a supporting part 11 arranged on the cabinet 2 and an abutting part 12 arranged on the cabinet door 3. The abutting part 12 can move to the supporting part 11 as the cabinet door 3 closes, so as to support the cabinet door 3 through the supporting part 11;

[0059] A locking mechanism 4, including a first mating part 41 arranged on the supporting part 11 and a second mating part 42 arranged on the cabinet door 3. The second mating part 42 can form a locking connection with the first mating part 41 as the cabinet door 3 closes.

[0060] In some embodiments, the chassis 2 can be understood to include, but not limited to, the chassis of devices such as refrigerators, induction cookers, baking ovens, dryers, etc. The cabinet door 3 can be installed on the chassis 2 through connecting members such as hinges and hinges, so that the cabinet door 3 has two application states of opening and closing on the chassis 2.

[0061] In some embodiments, the chassis 2 has a rectangular body structure, and an inner cavity for placing food or items is provided therein; the shape of the cabinet door 3 is adapted to the inner cavity. Wherein, when the cabinet door 3 is closed, it fits on the front side 21 of the chassis 2, and the cabinet door 3 does not occupy the internal space of the inner cavity.

[0062] In some embodiments, the first engaging portion 41 and the second engaging portion 42 are engaged with each other to form the locking connection. Wherein, the manner of the herein referred to engagement includes, but not limited to, the engagement relationship formed by the insertion of a bolt and a hole groove through insertion and fitting.

[0063] In some embodiments, the first engaging portion 41 and the second engaging portion 42 are attracted to each other to form the locking connection; for example, the first engaging portion 41 and the second engaging portion are arranged in a magnetic attraction form.

[0064] By providing the supporting mechanism 1, the cabinet door 3 can obtain the support of the supporting portion 11 at least in the closed state, so as to facilitate reducing the application fatigue and wear at the connection between the cabinet door 3 and the chassis 2, extending the service life of the connection between the cabinet door 3 and the chassis 2, and avoiding the phenomenon that the cabinet door 3 prematurely appears corner dropping or sagging during use.

[0065] And by providing the locking mechanism 4, it can facilitate improving the stability of the cabinet door 3 in the closed state, avoiding the cabinet door 3 accidentally disengaging from the support of the supporting portion 11, so that the user can have a better use experience.

[0066] As an application example thereof, one end of the supporting portion 11 is connected to the chassis 2, and the other end protrudes toward the front side of the chassis 2.

[0067] In some embodiments, the protruding length of the supporting portion 11 is adapted to the thickness of the cabinet door 3, so that when the cabinet door 3 is in the closed state, the supporting portion falls within the coverage range of the cabinet door 3 in the vertical direction, so that the cabinet door 3 can have a better external appearance in the closed state.

[0068] In some embodiments, when there is a gap between the cabinet door 3 in the closed state and the front side of the chassis 2, the protruding length of the supporting portion 11 is greater than the width of the gap and less than the sum of the width of the gap and the thickness of the cabinet door 3.

[0069] By arranging the supporting portion 11 to protrude towards the front side 21 of the chassis 2, it can better fit the application state of the cabinet door 3 on the chassis 2, so that the cabinet door 3 can be supported and carried by the supporting portion 11.

[0070] As an application example, as Figures 1 to 4 shown, the supporting portion 11 is arranged at the bottom of the chassis 2, and the abutting portion 12 is the bottom end face of the cabinet door 3.

[0071] In some embodiments, the supporting portion 11 is arranged on the bottom end face of the chassis 2. For example, the supporting portion 11 is arranged as a flat plate member. At this time, one end of the supporting portion 11 is connected to the bottom end face of the chassis 2, and the other end extends towards the front side 21 of the chassis 2 for supporting and carrying the cabinet door 3. In this application form, the bottom end face of the cabinet door 3 and the bottom edge of the front side 21 of the chassis 2 can be set to be flush, as Figure 2 shown.

[0072] In some embodiments, the supporting portion 11 is arranged at the bottom of the front side of the chassis 2. For example, the bottom end face of the cabinet door 3 is set to be higher than the bottom edge of the front side of the chassis 2, so as to leave a space between the bottom end face of the cabinet door 3 and the bottom edge of the front side of the chassis 2 to facilitate the installation of the supporting portion 11, as Figure 6 shown.

[0073] In some embodiments, a notch 31 is arranged on the bottom end face of the cabinet door 3, and the supporting portion 11 is arranged on the front side of the chassis 2 corresponding to the position of the notch 31. At this time, the bottom end face of the cabinet door 3 and the bottom edge of the front side of the chassis 2 can also be set to be flush, as Figure 5 shown.

[0074] By setting the abutting portion 12 as the bottom end face of the cabinet door 3, there is no need for additional structural design of the cabinet door 3, and the overall structure is simpler, which can facilitate reducing the structural complexity of the cabinet door and the design cost.

[0075] As an application example, at least two inner chambers are arranged in the chassis 2, and the number of the cabinet doors 3 corresponds to the number of the inner chambers one by one;

[0076] The cabinet doors 3 of two adjacent inner chambers share one support portion 11.

[0077] In some embodiments, there are two inner chambers, and the two inner chambers are arranged side by side in the horizontal direction. The cabinet doors 3 are correspondingly provided with two doors, and the installation connection parts of the two cabinet doors 3 and the chassis 2 are respectively located on the left and right sides of the chassis 2, so that the closing ends of the two cabinet doors 3 are both located in the middle of the chassis 2. At this time, the support portion 11 can be set to one, such as Figure 1 , Figure 2 as shown.

[0078] In some embodiments, the number of the inner chambers is an integer multiple of 2. For example, the number of the inner chambers is set to 4, 6, etc. Here, the case where the number of the inner chambers is set to 4 is taken as an example for illustration. At this time, the 4 inner chambers can be arranged side by side in the horizontal direction, or can be arranged in a matrix-like stacked manner, and one support portion 11 is shared between every two inner chambers, such as Figure 7 as shown.

[0079] In some embodiments, the length of the support portion 11 is adapted to the length of the front side of the chassis 2; in this structural form, the support area of the support portion 11 for the bottom end face of the cabinet door 3 can be increased, and the support stability can be improved; moreover, when the bottom end face of the cabinet door 3 is higher than the bottom edge of the front side of the chassis 2, it can also achieve a neat and beautiful effect, such as Figure 6 as shown.

[0080] By setting the cabinet doors 3 of two adjacent inner chambers to share one support portion 11, it is convenient to reduce the application quantity of the support portion 11, reduce the application cost, and make the assembly or processing simpler.

[0081] As an application example, the number of the support portions 11 corresponds to the number of the cabinet doors 3 one by one. Here, the case where the number of the inner chambers is set to two is continued as an example for illustration. At this time, the number of the cabinet doors 3 is set to two, and the number of the support portions 11 is also set to two.

[0082] In some embodiments, the two inner chambers are arranged side by side in the horizontal direction, and the closing ends of the two cabinet doors 3 are set to be located in the middle of the chassis 2. At this time, the two support portions 11 are arranged in the middle of the chassis 2.

[0083] In some embodiments, the two inner chambers are arranged side by side in the horizontal direction, and the closing ends of the two cabinet doors 3 are set to be respectively located on both sides of the chassis 2. At this time, the two support portions 11 are respectively arranged on both sides of the chassis 2, such asFigure 4 shown.

[0084] In some embodiments, the two inner chambers are arranged side by side in the horizontal direction, and the closed ends of the two cabinet doors 3 are arranged to be located at the side and the middle of the chassis 2 respectively. At this time, the two supporting parts 11 are also arranged at the side and the middle of the chassis 2 respectively. Figure 3 shown.

[0085] In some embodiments, the two inner chambers are stacked in the vertical direction, and the closed ends of the two cabinet doors 3 are arranged to be located on the same side of the chassis 2. At this time, the two supporting portions 11 are also arranged on the same side of the chassis 2. Figure 7 , Figure 11 shown.

[0086] In some embodiments, the two inner chambers are stacked in the vertical direction, and the closed ends of the two cabinet doors 3 are respectively located on both sides of the chassis 2 . At this time, the two supporting portions 11 are also respectively located on both sides of the chassis 2 .

[0087] By setting the number of the supporting portions 11 to correspond to the number of the cabinet doors 3 on a one-to-one basis, the flexibility of the cabinet doors 3 during installation and application can be improved.

[0088] As an example of one application, Figures 8 to 10 As shown, the first matching portion 41 is a locking groove 111 provided on the supporting portion 11, and the second matching portion 42 is a locking pin 32 provided on the cabinet door 3, and the locking pin 32 can move to extend into the locking groove 111;

[0089] Alternatively, the first matching portion 41 is a locking pin disposed on the supporting portion 11 , and the second matching portion 42 is a locking groove disposed on the cabinet door 3 , and the locking pin can move to extend into the locking groove.

[0090] The snap connection between the locking pin 32 and the locking groove 111 can facilitate the maintenance of the locked state of the cabinet door 3 after closing, avoiding accidental touching and causing the cabinet door 3 to be separated from the support of the supporting part 11, thereby improving the reliability of the dryer during use.

[0091] As an application example, the locking mechanism further includes an elastic member 43 , which is connected to the locking pin 32 and is used to provide a pre-tightening force to the locking pin 32 .

[0092] In some embodiments, the end of the lock pin 32 is extended out of the cabinet door 3, and the body of the lock pin 32 is slidably disposed in the cabinet door 3. The elastic member 43 is connected to the body of the lock pin 32 and is disposed inside the cabinet door 3. Figure 8 , Figure 9 shown.

[0093] In some embodiments, the elastic member 43 is a spring, and the spring is sleeved on the body of the locking pin 32 .

[0094] By setting the elastic member 43, a certain pre-tightening force can be provided to the lock pin 32, so that the lock pin 32 can have the performance of automatic reset, which is convenient for improving the flexibility of the lock pin 32 when in use and can improve the clamping reliability between the lock pin 32 and the locking groove 111.

[0095] As an example of one application, Figure 9 , Figure 10 As shown, the end 321 of the locking pin 32 is configured to be spherical, and the inner wall surface 1111 of the locking groove 111 is configured to be an arc surface.

[0096] In some embodiments, the body of the locking pin 32 is configured as a cylinder, and the end 321 of the locking pin 32 is configured as a spherical shape. The spherical setting of the end 321 and the use of the elastic member can improve the contact smoothness between the locking pin 32 and the supporting portion 11.

[0097] In some embodiments, at least one inner wall surface 1111 of the locking groove 111 is set to be an arc surface, and the arc surface is located in the escape direction of the lock pin 32. When the cabinet door 3 is opened from the closed state, the ball of the end 321 contacts the arc surface of the locking groove 111, which can reduce the force required by the user to open the cabinet door 3.

[0098] By designing the shape of the end of the locking pin 32 and the inner wall surface of the locking groove 111 , the convenience for the user when opening the cabinet door 3 can be improved.

[0099] As one application example, the supporting portion 11 is detachably connected to the chassis 2;

[0100] Alternatively, the supporting portion 11 and the chassis 2 are an integrated structure.

[0101] In some embodiments, the supporting portion 11 and the chassis 2 are arranged to be detachably connected; for example, the supporting portion 11 is mounted and fixed on the chassis 2 by fasteners such as bolts.

[0102] In some embodiments, the supporting portion 11 and the chassis 2 are of an integral structure; for example, the supporting portion 11 is welded and fixed to the chassis 2; or, the supporting portion 11 and the front side surface of the chassis 2 are formed by stamping.

[0103] As an application example, an inclined guiding surface 112 is provided at the front end of the supporting portion 11.

[0104] In some embodiments, the inclined guiding surface 112 is provided on the top end surface of the supporting portion 11, and the lower end of the inclined guiding surface 112 is connected to the front side surface of the supporting portion 11.

[0105] By providing the inclined guiding surface 112, it can play a guiding role when the cabinet door 3 is closed, and improve the smoothness of the cabinet door 3 during the closing operation.

[0106] As an application example, as Figure 12 , Figure 13 shown, the abutting portion 12 is a groove provided on the rear side surface of the cabinet door 3, and the supporting portion 11 can extend into the abutting portion 12 as the cabinet door 3 is closed.

[0107] In some embodiments, the abutting portion 12 can be set in the form of a groove, so that after the cabinet door 3 is closed, the supporting portion 11 can extend into the abutting portion 12, thereby forming a supporting effect on the cabinet door 3.

[0108] As an application example, as Figure 14 , Figure 15 shown, one end of the abutting portion 12 is connected to the cabinet door 3, and the other end protrudes towards the rear side of the cabinet door 3;

[0109] The supporting portion 11 is a groove provided on the front side surface of the chassis 2, and the abutting portion 12 can extend into the supporting portion 11 as the cabinet door 3 is closed.

[0110] In some embodiments, the supporting portion 11 can be set in the form of a groove, so that after the cabinet door 3 is closed, the abutting portion 12 can extend into the supporting portion 11, thereby forming a supporting effect on the cabinet door 3.

[0111] In addition, as Figure 1 , Figure 11 shown, in this embodiment, a dryer is also provided. The dryer can be used for drying food, medicinal materials or items. The dryer includes the chassis 2 and the cabinet door 3, and the above-mentioned cabinet door supporting device is provided on the dryer.

[0112] In the solution of this embodiment, by applying the cabinet door supporting device as described above to the dryer, the cabinet door 3 of the dryer can obtain a supporting effect through the cooperation between the supporting portion 11 and the abutting portion 12 when it is closed, avoiding the situation that the cabinet door 3 prematurely shows corner chipping or sagging during use, which is convenient for extending the service life of the dryer; and the provided locking mechanism can facilitate improving the stability of the cabinet door 3 in the closed state, thus facilitating improving the user experience when the user uses the dryer.
