Technical Field

The present invention relates to the field of household appliances, and in particular, to a laundry treating apparatus.

Background

Currently, a plurality of clothes treatment units are included in a clothes treatment device, such as a washing machine with a plurality of washing drums inside and a washing and drying all-in-one machine with one washing drum and one dryer inside, so that the requirements of different treatments on different clothes by one device are met. When a plurality of clothes treating units are provided with heaters, the total power of all loads in the circuit can exceed the total load power of the power line if the plurality of heaters work simultaneously, so that the circuit cannot work normally. Therefore, when designing the circuit, the clothes treating apparatus should be designed to avoid the situation that a load with larger power can be connected to the circuit at the same time.

There is a chinese invention patent that discloses a washing machine, comprising: a box body; the door body is arranged on the box body in a turnover manner; the three-phase motor is arranged in the box body; the three-phase motor braking device comprises a switching circuit which can be switched between a driving state and a braking state, wherein the switching circuit enables the three-phase motor to rotate when in the driving state, and the switching circuit brakes the three-phase motor by short-circuiting the three-phase motor when in the braking state; the rotating speed detection device is used for detecting the rotating speed of the three-phase motor and is arranged in the box body; the door body locking device is arranged on at least one of the door body and the box body; and the controller is communicated with the switching circuit, the rotating speed detection device and the door body locking device so as to control the door body locking device to lock the door body when the switching circuit is in a driving state and the detection value of the rotating speed detection device is greater than a preset value. Although the invention can convert the circuit of the washing machine, the circuit is not reasonably arranged according to the power of the device in the washing machine.

The prior Chinese invention patent provides a multi-load interlocking circuit and a control method thereof, wherein the multi-load interlocking circuit comprises an MCU, N loads and N relays, wherein N is an integer greater than 2; the normally open end of each relay is connected with one load, the control unit of each relay is connected with the MCU, the normally closed end of the ith relay is connected with the normally closed end of the (i + 1) th relay, and i is an integer larger than 0 and smaller than N; the control method comprises the following steps: the MCU detects whether a load control instruction input exists or not; if the load control instruction exists, the MCU provides a high level for the relay correspondingly connected with the load to be controlled pointed by the load control instruction, and outputs a low level to other relays in the N paths of relays. The circuit provided by the invention only has one load to work at any time, thereby ensuring the safety of household appliances and the safety of household electricity. The circuit is not suitable for a clothes processing device containing a plurality of clothes processing units because only one load works.

In summary, there is a need for a clothes treating apparatus, wherein the design of the internal circuit can ensure that the total power of the loads connected to the clothes treating apparatus at each time is less than the total load power of the power line, so as to ensure that the circuit in the clothes treating apparatus can work normally.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes the defect management modes in the embodiments in detail with reference to the drawings in the embodiments of the present invention.

The present invention provides a laundry treating apparatus having a plurality of laundry treating units incorporated therein. For example, a washing unit and a drying unit are arranged in the dry cleaning all-in-one machine; such as a double drum washing machine which can perform classified washing of laundry, includes two washing units and each washing unit can also perform a drying process. Since a plurality of laundry treatment units are included in the laundry treatment apparatus, a relatively large number of loads are connected to the electric circuit of the laundry treatment apparatus, and the relatively large number of loads include some high-power loads, such as a heater for drying and/or caring for laundry. In order to ensure that the total power in the electric circuit of the laundry treatment apparatus does not exceed the total load power of the power cord, it is necessary to control the kind and number of loads that can be connected in the electric circuit each time.

In view of the problem of ensuring the total power in the circuit of the clothes treatment equipment, the invention provides the circuit design of the clothes treatment equipment, so that the circuit of the clothes treatment equipment is communicated with at most one high-power load and one low-power load each time, and further ensures that the total power communicated into the circuit is lower than the total load power of a power line, and further ensures the circuit stability of the clothes treatment equipment.

The high-power load is a device with power exceeding half of the total load power of the circuit, and the low-power load is a device with power lower than the total load power of the circuit.

The present invention provides different circuit connection forms of the following 3 embodiments according to the above circuit design concept to meet the practical requirements. In addition, the connection in the circuit in the invention means that current flows, and the connection with a certain load means that a certain load can run and work when current flows. The positions of the live wire end and the zero wire end in each form of circuit connection diagram can be interchanged, and the contact A and the contact B of each single-pole double-throw switch in the circuit connection diagram can be interchanged in pairs. And the thermal power end in the circuit is the end directly connected with the power supply end, and the zero line end is the end connected with the grounding wire. All loads connected in a circuit have an input and an output in the direction of current flow.

Example 1

As shown in fig. 1 to 4, the laundry treating apparatus, which contains a plurality of high power loads and low power loads, is provided with a first circuit 1 connecting only all the high power loads, a second circuit 2 connecting only all the low power loads, the first circuit and the second circuit being connected in series or in parallel, and control means provided in the first circuit and the second circuit for controlling the laundry treating apparatus to connect at most one high power load and one low power load at a time. When at most one high-power load and one low-power load are connected in the circuit each time, the total load power of the circuit can be ensured to be smaller than the total load power of the power line, and the stability of the circuit is further ensured.
