Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a washing machine for cleaning tableware. Background Technology

[0002] Dishwashers are now widely used in home kitchens. Before or during the washing process, dishwashers typically heat the wash water, and after washing, they usually blow hot air into the washing chamber to dry the dishes.

[0003] For example, CN202221869592.7, "An Auxiliary Drying Device for a Cleaning Machine and a Cleaning Machine", discloses a solution that includes a water cup body, a housing, and a fan assembly located at the bottom of the cleaning machine cavity. The air inlet of the fan assembly is connected to the bottom space of the cleaning machine cavity, the air outlet of the fan assembly is connected to the air inlet of the housing, the air outlet of the housing is connected to the air inlet of the water cup body, and the air outlet of the water cup body is connected to the inside of the cleaning machine cavity. A heating plate and a water pump motor assembly are installed at the bottom of the water cup body, and the fan assembly is adjacent to the heating plate.

[0004] Although the aforementioned cleaning machine improves the drying effect through the combination of heating plate and fan assembly, both the heating plate and fan assembly modules require a large installation space, and the efficiency is low when the two modules operate independently. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cleaning machine that occupies less installation space and has high efficiency in heating washing water and drying after washing, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A washing machine includes an inner tank, at least the bottom wall of which is made of metal. The bottom wall of the inner tank is provided with spaced heating wires for heating the washing water or for drying after washing. The side wall of the inner tank is provided with an air inlet and an air outlet, and the air inlet is provided with an air guide structure that can blow air toward the bottom wall of the inner tank.

[0008] By adopting the above structure, the bottom wall of the metal inner tank is used as a heat transfer element to transfer heat, which greatly increases the heating surface of the water and helps to improve the heating efficiency of the washing water. When drying is required, the heating wire works and blows air through the air inlet and air guide structure to the bottom wall of the inner tank, which can quickly diffuse heat to the entire washing chamber, thereby achieving efficient drying of tableware. In addition, the bottom wall of the inner tank, as the heating surface, completely eliminates the problem of residual water at the bottom of the inner tank.

[0009] Preferably, the central portion of the bottom wall of the inner tank is the installation area for the water return assembly, and the bottom wall of the inner tank gradually slopes downward from the edge towards the installation area to form a guide surface, with the heating wire located below this guide surface. This structure facilitates improved water return efficiency during washing, and the guide surface can also guide the airflow during drying to achieve multi-directional air dispersion, thus improving the drying effect on the tableware.

[0010] Preferably, the air inlet is provided with multiple partitions arranged at intervals, and these partitions are gradually inclined towards the bottom wall of the inner liner from top to bottom. This result helps to improve the directional guidance effect of the air in the blowing liner, thereby improving the drying effect.

[0011] Preferably, the air inlet is located on the first side wall of the inner liner, and the air outlet is located on the second side wall of the inner liner opposite to the first side wall. The extension line of the partition is arranged near the edge of the mounting area close to the second side wall. This structure can further improve the dispersion effect of the air.

[0012] As an improvement, the two ends of the partition are rotatably positioned at the front and rear edges of the air inlet. This structure allows for adjustment of the airflow direction at the air inlet as needed, further enhancing the drying effect.

[0013] Preferably, the inner surface of the air inlet is provided with circumferentially arranged ribs, which are multiple and spaced apart along the axial direction of the air inlet. Each end of the partition has a clamping opening capable of holding the ribs within it. With this structure, the user can manually adjust the tilt direction of the partition as needed to control the airflow direction of the air inlet and enhance the drying effect in specific areas.

[0014] Preferably, the heating wire is spirally wound around the bottom wall of the inner liner. A control component connected to the heating wire and used to control its power is also provided at the bottom of the inner liner, and this control component is further equipped with a temperature sensor for detecting the temperature of the bottom wall of the inner liner. This distribution of the heating wire facilitates installation and allows for extensive coverage of the bottom wall of the inner liner, improving heating efficiency. The temperature sensor and control component facilitate real-time control of the heating process as needed.

[0015] Preferably, the inner liner is provided with an air guide pipe connected to the air inlet and a fan for blowing external air through the air guide pipe toward the air inlet. This utility model simplifies the air intake structure, eliminating the need for a heating element to heat the air; external air can simply be blown directly into the inner liner, thus reducing production costs.

[0016] Compared with the prior art, the advantages of this utility model are as follows: The bottom wall of the inner tank of this utility model is provided with a heating wire, and the metal bottom wall of the inner tank is used as a heat transfer element to transfer heat, which greatly increases the heating surface of the water and helps to improve the heating efficiency of the washing water; when drying is required, the heating wire works and blows air through the air inlet and the air guide structure to the bottom wall of the inner tank, which can quickly diffuse heat to the entire washing chamber, thereby achieving efficient drying of tableware. In addition, the bottom wall of the inner tank serves as the heating surface, completely eliminating the problem of residual water at the bottom of the inner tank. Attached Figure Description

[0022] Example 1:

[0023] like Figures 1-3 As shown, the washing machine of this embodiment includes an inner tank 1. The bottom wall of the inner tank 1 is made of metal. The bottom wall of the inner tank 1 is provided with heating wires 2 distributed at intervals. The heating wires 2 are used to heat the washing water or to heat the water for drying after washing. The side wall of the inner tank 1 is provided with an air inlet 11 and an air outlet 12. The air inlet 11 is provided with an air guide structure that can blow air toward the bottom wall of the inner tank 1.

[0024] By adopting the above structure, the bottom wall of the metal inner tank 1 is used as a heat transfer element to transfer heat, which greatly increases the heating surface of the water and helps to improve the heating efficiency of the washing water. When drying is required, the heating wire 2 works and blows air through the air inlet 11 and the air guide structure to the bottom wall of the inner tank 1, which can quickly diffuse heat to the entire washing chamber, thereby achieving efficient drying of tableware. In addition, the bottom wall of the inner tank 1 serves as the heating surface, completely eliminating the problem of residual water at the bottom of the inner tank 1.

[0025] The central part of the bottom wall of the inner tank 1 is the installation area 13 for the water return component. The bottom wall of the inner tank 1 gradually slopes downward from the edge towards the installation area 13 to form a guide surface 10, and the heating wire 2 is located below this guide surface 10. This structure facilitates improved water return efficiency during washing, and the guide surface 10 can guide the airflow during drying to achieve multi-directional airflow dispersion, thereby improving the drying effect on the tableware.

[0026] Multiple partitions 3 are arranged vertically at intervals at the air inlet 11, and these partitions 3 are gradually inclined towards the bottom wall of the inner liner 1 from top to bottom.

[0027] An air inlet 11 is located on the first side wall of the inner liner 1, and an air outlet 12 is located on the second side wall of the inner liner 1 opposite to the first side wall. The extension line of the partition 3 is arranged corresponding to the edge of the mounting area 13 near the second side wall. This structure can further improve the dispersion effect of the air.

[0028] The heating wire 2 is spirally wound around the bottom wall of the inner liner 1. A control component 4, connected to the heating wire 2 and used to control its power, is also located at the bottom of the inner liner 1. This control component 4 also includes a temperature sensor for detecting the temperature of the bottom wall of the inner liner 1. This distribution of the heating wire 2 facilitates installation and allows for extensive coverage of the bottom wall of the inner liner 1, improving heating efficiency. The temperature sensor and control component 4 facilitate real-time control of the heating process as needed.

[0029] The inner liner 1 is provided with an air guide pipe 5 connected to the air inlet 11 and a fan 6 for blowing external air through the air guide pipe 5 toward the air inlet 11. This embodiment simplifies the air intake structure, eliminating the need for heating elements to heat the air; external air can simply be blown directly into the inner liner 1, thus reducing production costs.

[0030] In this embodiment, a heating wire 2 is provided on the bottom wall of the inner tank 1, and the bottom wall of the metal inner tank 1 is used as a heat transfer element to transfer heat, which greatly increases the heating surface of the water and helps to improve the heating efficiency of the washing water.

In addition, the bottom wall of the inner tank 1 serves as the heating surface, completely eliminating the problem of residual water at the bottom of the inner tank 1.

[0031] Example 2:

[0032] The difference between this embodiment and Embodiment 1 is that:

[0033] like Figure 4As shown, in this embodiment, the two ends of the partition 3 are rotatably disposed at the front and rear edges of the air inlet 11. This structure allows for adjustment of the airflow direction at the air inlet as needed to further improve the drying effect.

[0034] Specifically, the inner surface of the air inlet 11 is provided with circumferentially arranged ribs 111. Multiple ribs 111 are spaced apart axially along the air inlet 11. The two ends of the partition 3 are respectively provided with clamping openings 31 that can movably hold the ribs 111.
