The cleaning machine can be a dish washer for cleaning objects to be cleaned such as tableware, kitchen ware and the like, wherein the tableware can comprise bowls, plates, dishes, chopsticks and the like, and the kitchen ware can comprise a pot, a basin and the like. In addition to this, the washing machine may also be used for washing other kinds of articles, for example, when the washing machine is used for washing laundry, it may correspond to a washing machine. In the embodiments of the present disclosure, the washing machine is mainly described by way of example with reference to a dishwasher, and other similar application scenarios may be referred to in the present disclosure, which is not described in detail herein.

For the washing machine, the washing machine is provided with a water inlet through which externally supplied water is supplied into the washing machine, thereby supplying washing water to the washing machine. In general, the washing machine is further provided with a water cup 3, a washing chamber 9, a washing pump, a shower arm, a drain pump 4, a drain outlet, and the like. The washer generally includes a plurality of wash modes, such as: pre-wash mode, power wash mode, energy saving wash mode, etc. When the cleaning machine enters a certain washing mode, water with a preset water quantity can be supplied into the water cup 3 through the water inlet; and starting a washing pump, wherein the washing pump drives water in the water cup 3 into the spray arm, and the water is sprayed to the object to be washed by the spray arm, so that the object to be washed is washed. The cleaned water is collected into the water cup 3 again under the action of gravity, so that the water is reused. When one of the washing modes is completed, the drain pump 4 may be activated to drain the water from the cup 3 and finally through the drain.

The bottom of the cup 3 is provided with an opening 30. The opening 30 may be used to connect a water sweep assembly. Specifically, the bottom of the water cup 3 is provided with a lowest position, and the opening 30 is provided at the lowest position of the water cup 3. When the opening 30 is provided at the lowest position of the water cup 3, it is advantageous to ensure a more reliable and efficient draining of the residual water in the water cup 3.

In embodiments provided herein, the water sweep assembly of the washer may include: a drainage culvert having opposed inlets and outlets, the inlets being connected to the openings 30; a first valve 6 disposed in said drain line adjacent said inlet; a second valve 7 disposed in the drain residue line near the outlet; the heating mechanism 2 is used for intermittently heating the residual water discharge pipeline; when the heating mechanism 2 is started, the second valve 7 is in a conducting state, and residual water in the residual water discharging pipeline can flow through the second valve 7 and then be discharged outwards; when the heating mechanism 2 is turned off, the first valve 6 is in a conducting state, and residual water in the water cup 3 can flow through the first valve 6 and then enter the residual water discharging pipeline.

In this embodiment, the water residue removing assembly mainly includes: a drain residue line, a first valve 6, a second valve 7 and a heating mechanism 2 arranged in the drain residue line. Wherein the first valve 6 is located at an upstream position near the inlet and the second valve 7 is located at a downstream position near the outlet.

When the heating mechanism 2 is started, the heating mechanism 2 heats the residual water discharging pipeline, air in the residual water discharging pipeline is heated and expanded, at the moment, the second valve 7 is automatically in a conducting state or is controlled to be in a conducting state by the controller, and the air is discharged outwards after flowing through the second valve 7; after the heating mechanism 2 is closed, air in the residual water draining pipeline is cooled and contracted to generate negative pressure, at the moment, the first valve 6 is automatically in a conducting state or is controlled by the controller to be in a conducting state, residual water in the water cup 3 flows through the first valve 6 and is pumped into the residual water draining pipeline, and residual water at the bottom of the water cup 3 is drained.

The heating mechanism 2 is started and shut down once each as one evacuation, and the number of evacuation times may be related to the volume of the residual water in the water cup 3, the volume of the residual water draining pipeline, the heating temperature of the heating mechanism 2, the current environmental temperature, and other factors, which are not limited herein.

In one embodiment, the cleaning machine may further include a drain pipe 8 communicating with the cup 3 and a drain pump 4 provided on the drain pipe 8, and an outlet of the drain residual water pipe is connected to the drain pipe 8 and located downstream of the drain pump 4.

It may be provided with a drain pipe 8 and a drain pump 4 for the washing machine. In general, the drain pump 4 may be disposed on a drain pipe 8, the drain pipe 8 being in communication with the water cup 3, and when the drain pump 4 is activated, a large portion of water in the water cup 3 may be discharged to the outside through the drain pipe 8.

In this embodiment, the outlet of the residual water discharging pipe may be connected to the water discharging pipe 8, and the water flowing out of the residual water discharging pipe may be discharged to the outside through the water discharging pipe 8. The outlet of the drain residue line may be located downstream of the drain pump 4. In general, the drain pump 4 is a centrifugal pump, and its principle of operation is to drain water by centrifugal action of an impeller. When air enters the impeller, the centrifugal effect is weakened or even eliminated. Generally, the drain pump 4 is disposed at the bottom of the water cup 3, and when water is discharged to the inlet of the drain pump 4, the pump cavity of the drain pump 4 will enter air, and the water in the pump housing of the drain pump 4 will not be discharged, which is a main reason that the water in the water cup 3 cannot be completely discharged. Because the centrifugal pump has the defects during drainage, in the embodiment of the application, the outlet of the drainage residual water pipeline is arranged at the downstream of the centrifugal pump, so that the drainage residual water pipeline and the drainage pump 4 are mutually independent and mutually non-interfering and mutually matched during drainage. Most of the water in the water cup 3 is discharged by the drainage pump 4, and the residual water in the water cup 3 is thoroughly drained by the residual water discharge pipeline.

In one embodiment, an intermediate chamber 10 having a predetermined volume is provided in the drain line, the intermediate chamber 10 being provided between the first valve 6 and the second valve 7. When the heating mechanism 2 is turned off, residual water in the water cup 3 can flow through the first valve 6 and then enter the middle cavity 10; when the heating mechanism 2 is activated, the residual water in the intermediate chamber 10 can flow through the second valve 7 and be discharged through the drain pipe 8.

In this embodiment, an intermediate chamber 10 having a certain volume may be provided in the drainage residual water pipe, the cross-sectional dimension of the intermediate chamber 10 may be larger than the cross-sectional dimension of the pipe at other positions in the drainage residual water pipe, and the intermediate chamber 10 may be provided between the first valve 6 and the second valve 7 to serve as a transition chamber during drainage of residual water. In particular, the intermediate chamber 10 may be in a closed box shape, and of course, the intermediate chamber 10 may also be in other shapes and configurations, which are not particularly limited herein.

When the water cup 3 is used for discharging residual water, the heating mechanism 2 can be started, the heating mechanism 2 is used for heating a residual water discharging pipeline, and air in the pipeline (mainly the middle cavity 10) is heated to expand so as to discharge water through the second valve 7; the heating mechanism 2 is closed, air in the pipeline (mainly the middle cavity 10) is cooled and contracted to generate negative pressure, and residual water in the water cup 3 is pumped into the middle cavity 10 through the first valve 6. After the water cup 3 is emptied once, the emptying operation can be circularly performed according to actual needs until the residual water in the water cup 3 is completely drained.

Further, the intermediate chamber 10 has a first port 101 and a second port 102, the residual water discharge line includes a first pipe section 103 connected between the opening 30 of the water cup 3 and the first port 101, and a second pipe section 104 connected between the second port 102 and the water discharge pipe 8, and the first port 101 is located higher than the second port 102 and spaced apart from the top of the intermediate chamber 10.

In this embodiment, the intermediate chamber 10 may be located in a drainage culvert, which divides the drainage culvert into a first pipe section 103 and a second pipe section 104. A first port 101 and a second port 102 are provided in the intermediate chamber 10. The first port 101 serves as an inlet of the intermediate chamber 10, and the second port 102 serves as an outlet of the intermediate chamber 10. Wherein a first pipe section 103 is connected between the opening 30 of the water cup 3 and the first joint 101 and a second pipe section 104 is connected between the second joint 102 and the drain pipe 8.

In order to ensure that as much water as possible can be drained from the intermediate chamber 10, the first port 101 may be located at a higher level than the second port 102. In addition, the first interface 101 is spaced a certain distance from the top of the middle cavity 10, the liquid level in the middle cavity 10 reaches a certain position poem, the pressure in the middle cavity 10 is equal to the pressure in the water cup 3, and water cannot continuously flow into the middle cavity 10, so that a certain amount of air can be ensured to be always arranged on the upper portion of the middle cavity 10. And the heating mechanism 2 is used for carrying out heat expansion and cold contraction by intermittently heating the part of air, so that the residual water in the water cup 3 is discharged outwards from the middle cavity 10 and is pumped into the middle cavity 10. The distance between the first interface 101 and the top is not specifically limited herein.

In one embodiment, the heating mechanism 2 includes a heating element and a controller electrically connected to the heating element, the controller controlling the activation and deactivation of the heating element.

In this embodiment, the heating mechanism 2 may include a heating member and a controller electrically connected to the heating member, and the activation and the deactivation of the heating member is controlled by the controller. The controller may be provided separately for the heating mechanism 2 or may be integrated into the controller of the washing machine. Specifically, the form of the controller is not specifically limited herein. The controller may store the operating mode of the heating element therein, for example, the controller may store a first time period from activation to deactivation of the heating element, and a second time period from activation to deactivation. The first duration and the second duration are used as a unit of duration for emptying. The specific time of the first time period and the second time period may be different according to the volume of the water cup 3, the volume of the intermediate cavity 10, the power of the heating element, and other parameters, which are not specifically limited herein.

Wherein, the specific form of heating piece includes any one or its combination of following: PTC heaters, other electrical heating elements.

In a specific embodiment, the heating element is a PTC heater, which is arranged outside the intermediate chamber 10.

The PTC heater is an electric heater based on a semiconductor material, and its operating principle is to heat by using the characteristics of a PTC (positive temperature coefficient) material. PTC materials are special semiconductor materials whose electrical resistance increases with increasing temperature, i.e. have a positive temperature coefficient characteristic. When the PTC heater is energized, a large amount of heat is generated when a current passes through the PTC material because the resistance of the PTC material increases with an increase in temperature, thereby increasing the temperature of the PTC material and the surrounding environment. When the temperature rises to a certain degree, the resistance value of the PTC material increases sharply, thereby restricting the flow of current, so that the heating power decreases, and a self-stabilized state is achieved.

That is, when the heating member is a PTC heater, it reaches a state where the temperature is constant after being raised to a predetermined temperature, and it is not necessary to monitor the highest temperature of heating. When the heating element is a PTC heater, the controller can control the water draining action time only by heating time (such as heating for 1 minute and cooling for 2 minutes for water pumping and draining). The PTC heater can ensure that the heating element can accurately reach the set temperature after being started, and control is simplified; in addition, the PTC heater is arranged to prevent the heating element from being overtemperature, so that the PTC heater is safe and reliable to apply to the cleaning machine.

In another specific embodiment, the heating element may be an electric heating rod, and the residual water removing assembly further includes a temperature sensor for detecting the temperature of the intermediate chamber 10, and the temperature sensor is electrically connected to the controller.

In this embodiment, the heating element may be in the form of an electric heating rod, and when the heating element is in the form of an electric heating rod, a temperature sensor may be provided in order to obtain a heating temperature after the heating element is started, so as to reach a preset heating temperature. The temperature sensor is electrically connected with the controller, when the heating element is started, the temperature of the middle cavity 10 can be obtained by using the temperature sensor, and when the temperature of the middle cavity 10 reaches the preset temperature, the controller can adaptively control the working parameters or the working state of the heating element.

In one embodiment, the first valve 6, the second valve 7 may comprise the following forms: a one-way valve and an electric control valve.

In this embodiment, the first valve 6 and the second valve 7 are matched to realize the on-off of different positions in different stages in the residual water draining pipeline. Wherein, when the residual water is discharged outwards, the second valve 7 positioned at the downstream is opened, and the first valve 6 positioned at the upstream is closed; when the residual water in the cup 3 is led out, the first valve 6 located upstream is opened and the second valve 7 located downstream is closed. The first valve 6 and the second valve 7 may be any one or a combination of a check valve and an electrically controlled valve.

Of course, the specific arrangement of the first valve 6 and the second valve 7 may be other ways, and is not limited to the above description, and other modifications are possible to those skilled in the art in light of the technical spirit of the present application, but all the functions and effects implemented by the present application are included in the protection scope of the present application as long as they are the same as or similar to the present application.

In a specific embodiment, the first valve 6 is a first one-way valve, the second valve 7 is a second one-way valve, the first one-way valve is in one-way communication with the intermediate chamber 10 from the opening 30, and the second one-way valve is in one-way communication with the drain pipe 8 from the intermediate chamber 10.

In the present embodiment, the first valve 6 and the second valve 7 may be check valves. When the first valve 6 is a one-way valve, it is in one-way communication from the opening 30 to the intermediate chamber 10. When the second valve 7 is a one-way valve, it is in one-way communication from the intermediate chamber 10 to the drain pipe 8. When the first valve 6 is a one-way valve and the second valve 7 is a one-way valve, no additional control is needed, the air in the middle cavity 10 is intermittently heated only through the heating mechanism 2, the one-way valve is automatically operated by utilizing the pressure difference generated by expansion caused by heat and contraction caused by cold, and the first valve 6 and the second valve 7 can reliably ensure that residual water flowing out of the water cup 3 cannot flow back in the discharging process.

When the first valve 6 and the second valve 7 are both check valves, the residual water removal assembly works as follows:

when the heating mechanism 2 is started to heat the middle cavity 10, air in the middle cavity 10 expands, the second valve 7 serving as a one-way valve is automatically opened when a certain pressure is reached, and then water in the middle cavity 10 is discharged outwards; when the heating mechanism 2 stops heating, the air in the middle cavity 10 can be cooled and contracted, the pressure at the water cup 3 is larger than the pressure in the middle cavity 10, and the first valve 6 serving as a one-way valve is automatically opened, so that residual water in the water cup 3 is pumped into the middle cavity 10. At this time, since the second valve 7 is a one-way valve, it is connected in one direction from the intermediate chamber 10 to the drain pipe 8, and the discharged water does not flow back into the intermediate chamber 10.

In another specific embodiment, the first valve 6 is an electric control valve, the second valve 7 is an electric control valve, the first valve 6 and the second valve 7 are respectively and electrically connected with the controller, and when the heating element is started, the first valve 6 is in a closed state; the second valve 7 is in an open state; when the heating element is turned off, the first valve 6 is in an open state and the second valve 7 is in a closed state.

In this embodiment, the first valve 6 and the second valve 7 may be electrically controlled valves, and when the first valve 6 and the second valve 7 are electrically controlled valves, they may be electrically connected to a controller, respectively, and the working states of the first valve 6 and the second valve 7 may be controlled by the controller electrically connected to the heating element. Specifically, when the heating element is started, the controller may control the first valve 6 to be in a closed state, and the second valve 7 to be in an open state, so that the air in the intermediate chamber 10 expands due to heat, and the residual water in the intermediate chamber 10 is discharged outwards through the second valve 7, but cannot flow to the water cup 3 through the first valve 6. When the heating element is turned off, the controller can control the first valve 6 to be in an open state, the second valve 7 to be in a closed state, air in the middle cavity 10 is cooled and contracted, and certain negative pressure can be generated at the position of the opening 30 connected with the water cup 3 under the condition that the second valve 7 is in the closed state, so that residual water in the water cup 3 is sucked into the middle cavity 10.

In one embodiment, the heating element is disposed outside the intermediate chamber 10 and is at least partially disposed in contact with the intermediate chamber 10.

In this embodiment, the heating member may be disposed outside the intermediate chamber 10. When the heating element is arranged outside the intermediate chamber 10, it may be arranged at least partly in abutment with the intermediate chamber 10. The air in the intermediate chamber 10 can be efficiently heated when the heating member is activated.

In another embodiment, the heating element is arranged inside the intermediate chamber 10.

In the present embodiment, the heating element may be provided inside the intermediate chamber 10. When the heating member is disposed inside the intermediate chamber 10, a specific position of the intermediate chamber 10 is set according to a specific form of the heating member or the like. When the heating element is arranged above the first interface 101 (at the middle upper part of the middle cavity 10), the heating element is at least partially attached to the inner wall of the middle cavity 10, or the heating element can be suspended in the middle cavity 10; alternatively, the heating element may be located in the lower portion of the intermediate chamber 10.

As shown in fig. 1, in one embodiment, the cleaning machine further includes: the fan is used for supplying air to the drying air duct 5, and at least part of the heating piece is arranged on the drying air duct 5.

In this embodiment, the cleaning machine may include a blower and a drying duct 5, and after the blower is started, the blower supplies air to the drying duct 5. For the cleaning machine, the drying duct 5 may flow through the washing chamber 9 for drying the inner wall of the washing chamber 9.

At least part of the heating member is disposed on the drying duct 5. When at least part of the heating element is positioned on the drying air duct 5, the hot air blown by the fan can be heated and raised when flowing through the heating element, so that hot air is formed, the washing cavity 9 is dried efficiently, and meanwhile, the air in the middle cavity 10 can be heated.

Specifically, the heating element may have opposite upper and lower surfaces, at least a portion of which may be disposed in contact with the cup 3, and at least a portion of which may be disposed in contact with the intermediate chamber 10, such that heat can be transferred to both the cup 3 and the intermediate chamber 10 when the heating element is activated.

As shown in fig. 2, the heating member may be further disposed outside the intermediate chamber 10 and spaced apart from the intermediate chamber 10, and the intermediate chamber 10 is disposed on the drying duct 5.
