[0026] The application will be further described in detail below in combination with the drawings and specific embodiments.

[0027] The present invention discloses a dishwasher, including a motor 3 disposed at the bottom of an inner tank 1 and a water tank 2 connected to the drain outlet at the bottom of the inner tank 1. The motor 3 is sealed outside by a volute, and a water outlet 5 is opened on the volute. The water outlet 5 is inclined downward and connected to the water outlet of the water tank 2 through a connecting piece 4. The center line of the water outlet 5 has an angle with the horizontal plane where the top of the volute is located.

[0028] Inside the dishwasher, the motor 3 is fixed in the space below the bottom of the inner tub 1, above the base 7, and on the side of the sink 2, as shown below. Figure 1 As shown, the bottom surface of the inner tank 1 is not flat, but rather high around the edges and low in the middle, gradually sloping downwards from the edges towards the center (not necessarily the center point of the bottom of the inner tank 1) where it connects with the water tank 2. At the bottom of the inner tank 1, the motor 3 is fixed to the base 7 via the mounting bracket 6. The motor 3 has a volute casing on its exterior, with an inlet (not shown in the figure) and an outlet 5 on the volute casing. To minimize the distance between the motor 3 and the bottom of the inner tank 1 and improve the space utilization of the bottom of the inner tank 1, in the embodiment provided by this invention, the inclined space at the bottom of the inner tank 1 is fully utilized, and the fixed position of the motor 3 is moved upwards. At the same time, due to the upward movement of the motor 3, the outlet 5 of the motor 3 and the outlet of the water tank 2 are not on the same horizontal plane. Therefore, in the embodiment provided by this invention, after the fixed position of the motor 3 is moved upwards, the outlet 5 is tilted downwards, so that the center line and the horizontal surface where the top of the volute casing is located have a certain angle. The size of the angle can be calculated based on the size of the motor, the size of the volute casing, the size of the outlet, and combined with fluid dynamics calculations. Generally, it can be controlled between 15° and 30°, such as setting the angle to 19°. The center line of outlet 5 is in the same direction as the water outlet direction of motor 3. A vent hole (not shown in the figure) is provided on the top of the volute, which allows air bubbles generated during water flow to enter the cavity at the top of motor 3 and be discharged from the vent hole when motor 3 is running, thus avoiding air accumulation in the volute and reducing the working efficiency of motor 3.

[0029] like Figure 1As shown, the water outlet 5 and the water outlet of the sink 2 are communicated through the communicating piece 4, so that the washing water enters the sink 2 at a set flow rate and pressure under the action of the motor 3, and then is sprayed through the sprayer, thereby realizing the dish washing operation. The middle part of the communicating piece 4 is bent, so that the overall structure is generally V-shaped, the included angle formed between the two sides of the V-shaped structure is obtuse, and the connection part of the two sides is rounded, so that the two sides are smoothly connected, the obtuse angle is arranged, and the two details basically do not affect the flow rate, pressure and other flow factors of the washing water flow of the communicating piece 4. The communicating piece 4 is placed obliquely, one end is communicated with the water outlet 5, the other end is communicated with the sink 2, and the side wall of the communicating piece 4 on the side communicated with the sink 2 is horizontally arranged. The connection parts of the communicating piece 4, the water outlet 5 and the sink 2 are all provided with sealing rings to avoid water leakage. The connection mode of the communicating piece 4 with the sink 2 and the water outlet 5 adopts the existing fixing mode, such as plug-in connection, clamping connection and the like, and the connection part is fastened and sealed, which is not required and limited herein. On the outer side of the wall of the communicating piece 4, a plurality of reinforcing ribs are arranged in the circumferential direction. Generally, the reinforcing ribs are arranged along the circumferential direction of the outer wall of the communicating piece 4 to strengthen the strength of the outer wall of the communicating piece 4.

[0030] The motor 3 is fixed on the base 7 through the mounting seat 6. In order to further improve the space utilization rate, reduce the overall height of the dishwasher, reduce the operation noise of the motor and reduce the resonance between the motor and the shell, two embodiments of the mounting seat are provided in the application.

[0031] Embodiment one: one end of the mounting seat 6 is fixed with the base 7, and the other end is fixed with the side part of the motor 3, so that the bottom of the motor 3 can be directly placed on the base 7, or there is a minimum distance between the motor 3 and the base 7, so as to avoid transmitting the vibration of the motor 3 to the base 7 and causing the vibration of the dishwasher shell. A resilient pad can be arranged between the motor 3 and the base 7 to absorb the vibration during the operation of the motor 3 and reduce the noise.

[0032] As shown in Figure 2 and Figure 3 , one end of the mounting seat 6 is fixed with the base 7, and the other end is fixed with the side part of the motor 3. The mounting seat 6 can have multiple, respectively fixed with the side part of the motor 3 in different directions. It is recommended that each mounting seat 6 is symmetrically distributed around the motor 3. Of course, when the mounting seat 6 is arranged, other elements should be avoided, so that the motor 3 can work stably.

[0033] The mounting seat 6 includes a support piece 61, an elastic piece 62 and a fixing piece 63 connected in sequence. The support piece 61 can be fixed with the base 7 by screws or other ways, or can be integrally formed with the base 7. The fixing piece 63 is fixed with the side part of the shell (or volute) of the motor 3 by bolts. In actual application, the fixing piece 63 can be integrally formed with the shell / volute of the motor 3 and has a structure capable of being fixed with the elastic piece 62. One end of the elastic piece 62 is connected with the fixing piece 63, and the other end is fixed with the support piece 61.

[0034] As shown in Figure 3 , there is a step on the base 7, the support 61 is fixed on the step, the step can increase the height of the support 61, the height of the support 61 can be adjusted through the step, and when the support 61 is fixed on the base 7 through screws, the support 61 can be fixed on the step through screws, the base 7 is integrally formed with the step, and the base 7 is not provided with screw holes, so that when water leaks in the tank, the water leaks out of the tank from the screw holes. In actual application, when sufficient consideration is given to water leakage treatment, or when the support 61 is integrally formed with the base and the height is sufficient, the step can also not be provided. The fixing member 63 is fixed on the side of the motor 3 housing / volute through a bolt, or is integrally formed with the side of the motor 3 housing / volute. As shown in Figure 4 , the elastic member 62 is generally V-shaped, each end has an installation hole 64, which is used to be fitted with the fixing member 63 and the support 61 respectively, and the opening direction and position of the installation hole 64 are related to the fitting position of the fixing member 63 and the support 61. The fixing member 63 and the support 61 are each provided with a fitting part matched with the installation hole 64, and the fitting part and the installation hole 64 are in interference fit. The elastic member 62 can be a rubber member to reduce the vibration of the motor 3 during operation and reduce the operating noise. The two side edges of the V-shaped elastic member 62 are obtuse angles, and the specific angle can be determined according to the relative position and height difference between the fixing member 63 and the support 61. It should be noted that the motor 3 can be fixed on the base 7 through a plurality of mounting seats 6, and because other elements are arranged at the bottom of the inner container 1, the height of the support 61 of each mounting seat 6, the structure of the elastic member 62, the opening position and direction may be different, and need to be set according to the specific situation.

[0035] Embodiment two: as shown in Figure 5 , the mounting seat 6 is supported at the bottom of the motor 3, the mounting seat 6 is fixed on the base 7 through the support column 13, the support column 13 is integrally formed with the base 7, and the mounting seat 6 is made of a material with certain elasticity, such as elastic rubber, as shown in Figure 6As shown, the mounting base 6 is integrally formed with the support portion 11 and the bottom portion 12. The top surface of the support portion 11 has an arc-shaped surface matching the shape of the bottom of the motor 3. The arc length is 1 / 2 of the circumference, or less than 1 / 2 of the circumference but greater than 1 / 4 of the circumference. The bottom portion 12 is generally U-shaped. The bottom of the U-shaped structure is a horizontal surface, which is used to support the motor 3 when the motor 3 is seated on the base 7. The two side edges of the U-shaped structure are outwardly inclined and have multiple continuous bends, forming multiple steps. The top of the two side edges of the bottom portion 12 is outwardly bent. The two ends of the support portion 11 are also outwardly bent, forming the mounting portion 14. The mounting portion 14, the support portion 11 and the bottom portion 12 are integrally formed, fixing the position of the motor 3 and securing the motor 3 to the base 7.

[0036] In this embodiment, the mounting base 6 is in the form of a strip. Each end of the strip has a mounting portion 14. The mounting portion 14 on each side has a fixing hole 10. The base 7 has a support column 13. The fixing hole 10 is sleeved on the support column 13. The fixing hole 10 is in interference fit with the support column 13, preventing the mounting base 6 from being separated from the support column 13. In this embodiment, the diameter of the two ends of the support column 13 is smaller than the diameter of the middle portion, and the transition is smooth. The diameter of the inside of the fixing hole 10 is the same as the diameter of the two ends of the support column 13, and is consistent from top to bottom. When the fixing hole 10 is sleeved on the support column 13, the middle portion of the fixing hole 10 is expanded, achieving interference fit. The support column 13 can be integrally formed with the base 7, or as described in the first embodiment, the base 7 has a step, and the support column 13 is arranged on the step. The base 7, the support column 13 and the step are integrally formed. The mounting base 6 can be fixed to the base 7 through the cooperation of the fixing hole 10 and the support column 13, or can be directly fixed to the base 7 or the step of the base 7 by bolts.

[0037] The motor 3 is directly seated on the support portion 11 and is supported and fixed by the mounting base 6. The support portion 11 has sufficient width. The top surface of the support portion 11 has the same shape as the bottom of the motor 3, which is generally arc-shaped. The support portion 11 has a clearance area 15 for mounting other auxiliary structures on the housing of the motor 3. The clearance area 15 can form a limiting structure to prevent the motor 3 from moving on the support surface 11. In this embodiment, the mounting base 6 is in the form of a strip. The width of the strip can be determined according to the positions of other components arranged on the base 7, and can also be adapted to the shape of the bottom of the motor.

[0038] The two ends of the mounting base 6 are fixed to the support column 13. The bottom portion 12 is directly seated on the base 7 or has a certain space from the base 7, preventing the vibration generated by the motor 3 during operation from being transmitted to the base 7 through the mounting base 6 and causing resonance with the base 7. The body of the mounting base 6 between the bottom portion 12 and the support portion 11 has multiple damping holes 9 for reducing the vibration and noise generated by the motor 7 and reducing the overall weight of the mounting base 6. There are no damping holes 9 between the lowest end of the support portion 11 and the horizontal surface of the bottom portion 12, so as to reduce the installation height of the motor 3.

[0039] In the present application, the position of the motor 3 is raised, and the water outlet 5 is inclined downward to make full use of the inclined space at the bottom of the inner container 1, and the structure of the communication member 4 is adaptively improved, and further to improve the space utilization, the fixing mode of the motor 3 is improved to form the structure of the mounting seat 6, in actual application, for the existing machine type, the space utilization in the box can be improved by raising the position of the motor 3 and improving the structure of the communication member 4, and the improvement cost is low.

[0040] In summary, the present application provides a kind of dish washer, compared with prior art, motor 3 water outlet 5 downwardly inclined, the installation position of motor 3 is moved up, make full use of the space at the bottom of the inner container 1, improve space utilization, and can make the position of the base 7 move up, reduce the overall height of the dish washer;Mounting seat 6 is fixed with the side of motor 3, rather than fixed at the bottom, further improve the space utilization inside the dish washer.
