Description

The drum-type clothes washer-dryer
Technical field
The utility model relate to a kind ofly do washing successively in the drum in rotation, the drum-type clothes washer-dryer of each strokes such as rinsing, dehydration, drying.
Background technology
The formation of existing this drum-type clothes washer-dryer as shown in figure 11.Below its structure is described.
As shown in Figure 11, casing 1 inside supports steel ladle 4 by a plurality of vibration-damped components 2 and damped part 3, and the peristome of steel ladle 4 is opened or closed by door 5.Be provided with in the steel ladle 4 rotating shaft be on the incline direction roughly, can rotate rotation drum 6 freely, be provided with many limberss 7 and plate washer 8 in this rotation drum 6.
Be provided with laundry water intaking valve (water feed apparatus) 9 and drying water intaking valve 10 in the casing 1, the water discharge outlet 11 that is located in the steel ladle 4 is connected by drainage channel 13 and draining pump (drainage arrangement) 12.Air blast 15 is by blowing mouth 14 air blast in steel ladle 4, and air blast 15 is connected with heater 16, and the heat exchanger 17 by being connected with steel ladle 4 inside and air blast 15 constitutes a series of drying circulation canal.Water supply hose 18 is used for from the 17 interior water fillings of drying water intaking valve 10 heat exchanger.
The following describes the laundry in the said apparatus, the operation in the drying stroke.Drop into washings in rotation drum 6, when starting the laundry stroke, at first open laundry water intaking valve 9, water filling in steel ladle 4 enters till the water level of regulation.Next, drive rotation drum 6 with about 50 rev/mins rotating speed, the clothing that is dropped into is put on repeatedly, is thrown by plate washer 8, and the impulsive force when utilizing lotion water and falling the water surface is cleaned clothing.
When the laundry stroke finished, draining pump 12 was driven, by the drainage channel 13 water discharge of will do washing.After draining finishes, rotation drum 6 is rotated with about 1000 rev/mins rotating speed at a high speed, dewater.After the dehydration stroke finishes, carry out the drying stroke.
In the drying stroke, the same rotation drum 6 that drives with the laundry stroke, on one side the washings in the rotation drum 6 is stirred, on hot blast after will being heated by air blast 15 and heater 16 on one side blows to clothing in the rotation drum 6 from blowing mouth 14, make in the clothing in contained moisture be heated, evaporate.
And the air that contains steam high temperature is admitted in the heat exchanger 17, and the cooling water that infeeds in the heat exchanger 17 with drying water intaking valve 10 mixes, and heat exchange takes place, thereby carry out cooling and dehumidifying.And the air that has been dehumidified is heated once more by heater 16, and the clothing of putting into rotation drum 6 is carried out drying.Like this, just form a series of drying circulation.
In such existing apparatus; when in the casing 1 that size is restricted, wanting to form a series of drying circulation canal; because must guarantee the gap of casing 1 and steel ladle 4, thereby can not form the heat exchanger 17 with sufficient sectional area, this is disadvantageous to the drying performance.
And, thereby this heat exchanger 17 adopts is to rely on the blast of circulated air that cooling water is dispersed in heat exchanger 17 very equably to carry out the mode of heat exchange.When at will increasing air circulation in order to improve the drying performance, the heat exchanger 17 interior blast that section configuration is very little will too rise, disequilibrium between the hydraulic pressure of the cooling water that can and disperse, and cooling water can be blown up, arrive heater 16, exist the problem that the drying performance significantly descends.
And when the long clothing of dry foot and the clothing etc. that is stained with the hair of pet were carried out drying, these maos might be piled up in the inside of heat exchanger 17, the initiating device fault.
